    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    Uterine cervical cancer is globally the third most common cancer among women, and shows high mortality with invasive cervical carcinoma. Early detection of the disease, its correct staging, and treatment are therefore of great importance. The staging system updated in 2009 by the International Federation of Gynecology and Obstetrics (FIGO), is commonly used for planning the treatment. However, there are significant inaccuracies in the FIGO staging system. Accurate tumor staging is very important to decide the treatment strategy. Although not included in the staging system, magnetic resonance (MR) imaging is a valuable tool for local staging of the disease, and is useful in assessing the spread of the tumor and metastatic lymph nodes, thereby becoming a more accurate substitute for clinical staging of cervical carcinoma. In addition, it is capable of assessing the disease response to surgery or chemoradiation. This review briefly describes the role of MR imaging and the basic MR scanning protocol in evaluating cervical carcinoma. The MR findings with staging, and MR evaluation of treatment response, are further addressed.

    In patients with cervical carcinoma the selection of the optimal therapy depends on the precise preoperative assessment of the extent of disease. Currently, decisions regarding the management of these patients are made on the basis of clinical (FIGO) staging that has 50% mean error rate. To investigate the value of MR imaging in staging patients with invasive cervical cancer, we performed 25 MR examinations on 23 patients with histologic diagnosis of cervical cancer. All patients were clinically considered as having stage IB or IIB disease and underwent radical hysterectomy, providing specimens for pathologic correlation. The overall accuracy of MR imaging in staging cervical carcinoma (stage IB-IIB) was 78.1%. MR imaging seems to be the most reliable preoperative modality for staging invasive cervical cancer

    To evaluate the significance of vaginal air seen on CT scan in preoperative staging of uterine cervical carcinoma. A comparison was made between CT findings of vaginal fir and true vaginal involvement status in 85 patients with uterine cervical carcinoma. CT findings were analyzed in terms of the presence or absence of vaginal air, number of CT slices in which vaginal air was seen, shape of vaginal air, and relation of vaginal air to cervical mass. Vaginal air was present in 35 patients and was absent in 50. Although the mere presence of vaginal air or multiplicity of CT slices showing vaginal air did not signify the presence of vaginal involvement, vaginal air with irregular margin or vaginal air adjacent to uterine cervical mass was suggestive of vaginal involvement. These observation of vaginal air in interpreting CT may be helpful in the preoperative staging of uterine cervical carcinoma

    Full Text Available Background & objectives: Staging of cervical carcinoma is done clinically using International Federation of Obstetrics and Gynecology (FIGO guidelines. It is based on physical examination findings and also includes results of biopsy, endoscopy and conventional radiological tests like chest radiograph, intravenous urography and barium enema. These conventional radiological investigations have largely been replaced by computed tomography (CT and magnetic resonance imaging (MRI at present. FIGO staging system does not consider CT and MRI mandatory; however, use of these modalities are encouraged. This prospective study was conducted to determine the role of CT in staging work up in women diagnosed with cervical carcinoma. Methods: Fifty three women diagnosed with cervical carcinoma were evaluated with contrast enhanced CT scan of abdomen and pelvis. CT scan images were especially evaluated to determine tumour size, invasion of parmetrium, pelvic walls, rectum, urinary bladder and ureters, pelvic or retroperitoneal lymphadenopathy and distant metastases. CT findings were associated with clinical findings and staging, including findings from cystoscopy and sigmoidoscopy. Results: There was a poor agreement between clinical and CT staging of cervical carcinoma. Primary tumour was demonstrated on CT in 36 (70% of 53 patients. CT underestimated the parametrial, vaginal and pelvic wall invasion when compared with physical examination. CT overestimated the urinary bladder and rectal invasion when compared with cysto-sigmoidoscopy, however, CT had 100 per cent negative predictive value (NPV to exclude bladder and rectal involvement. CT detection of lymph node enlargement and lung metastases influenced the management. Interpretation & conclusions: Our findings show that CT scan does not reliably correlate with clinical FIGO staging of cervical cancer. However, it can detect urinary obstruction as well as nodal or distant metastases and thus improves the

    Objective: To evaluate the overall complications, major as well as minor, in patients treated for early-stage cervical carcinoma as related to treatment parameters. Methods: In this retrospective study, 167 consecutive patients with early-stage cervical carcinoma treated with preoperative radiotherapy and radical hysterectomy were investigated. Clinical data were collected from the medical files. Results: Transient or permanent complications appeared in up to half of all patients. Seven percent exhibited intraoperative complications and 35% suffered from early postoperative urinary tract problems; most frequently urinary tract infection. After one year, the urinary tract complications dominated; voidance difficulties and incontinence being most common. Gastrointestinal complications occurred in 15% of patients. Lymphedema appeared during the first year in 21% of the patients but several of the mild or moderate cases improved after the first year. The relative risk of lymphedema was increased with shorter duration of surgery, extensive preoperative irradiation to the bladder and after external postoperative irradiation. Some form of late sequelae remained in every fifth patient, and every fourth patient, aged 23-44 years, periodically suffered from vasomotor symptoms despite estrogen replacement therapy. Conclusion: The complications after radiotherapy and radical hysterectomy in early stage cervical carcinoma suggest that attempts should be made to evaluate effective treatments designed to minimize risk to the patients.

    The vaginal smear specimens of the patients who received operative therapy, irradiation or chemotherapy for cervical carcinoma were examined. Long-term follow-up vaginal cytology following treatment of cervical carcinoma is effective for the detection of local recurrence in an early stage. Serial cytology is also useful in evaluation of the effects of irradiation and chemotherapy for cervical carcinoma. Radiosensitive and prognostic significance of vaginal smears before and after radiation therapy was discussed. (author)

    The present study revealed that irradiation-induced changes of repopulation and redistribution played an important role in radiosensitivity and cure process of human uterine cervical carcinoma. DNA measurements by a microspectrophotometer were made on Feulgen stained biopsy specimens obtained from 20 patients. On the other hand, flow-microfluorometric measurements with Fried's computed cell cycle analysis were made on transplanted human cervical carcinomas. The mean nuclear DNA amount of human cervical carcinoma cells increased according as the irradiation doses increase until 2,000 rad. Moreover, as regards with the mean nuclear diameter of cancer cells the same phenomenon was recognized, and there was an interrelation between the increase of mean nuclear DNA amount and that of mean nuclear diameter. This phenomenon was proved in nuclear DNA analysis by flow-microfluorometric measurements on transplanted human cervical carcinoma in nude mice. Computed cell cycle analysis of F.M.F. data demonstrated that this phenomenon was due to irradiation-induced changes of repopulation and redistribution. That is to say, irradiation induces the increase of cycling cells and then partial synchronization to G2-M stage. Examination of the interrelation between this phenomenon at 500 rad and 5 years survival rate demonstrated that there was more increase of nuclear DNA amount in the good prognosis group than in the poor prognosis group. Estimation of residual cells near the G1 stage at 2,000 rad demonstrated that there were more residual cells near the G1 stage in the poor prognosis group than in the good prognosis group. (author)

    To demonstrate the benefits of magnetic resonance imaging (MRI) for the staging of endometrial carcinoma and to compare the results of the spin echo (SE) sequence in T2 with the results of the pos gadolinium intravenous study. We have studied 51 women diagnosed with endometrial carcinoma by means of a D and C and confirmed surgically using T1 equipment. All of them have had SE T1 axial sequences, SE in protonic density (PD) and T'' on an axial and sagittal plane carried out on them and 32 cases were studied after the administration of gadolinium intravenously (i. V.). We have valued the depth of the myometrial infiltration and the cervical invasion. The positive predictive value (PPV) and the negative predictive value (VPV) of the MRI to value the deep infiltration of the endometrium were 87.9% and 77.8% respectively. In the 32 cases where we administered gadolinium we obtained a PPV of 90% and a NPV of 83.8%, in both the SE T2 study and the contrast study. In the diagnosis of the cervical invasion we have obtained PPV and NPV values of 75% and 88.1% respectively. In the group of the 32 cases that had the contrast agent administered, we have obtained the same results in both the series: PPV of 80% and NPV of 85.2%. We have found a high correlation index between the staging using MRI and pathological anatomy, especially in stages I and II of the IFGO (International Federation of Gynecology and Obstretics) classification. The use of gadolinium has not varied the results obtained with the SE T2 series. (Author) 18 refs

    The objective of this study was to evaluate the efficacy of transvaginal contrast for local staging of cervical carcinoma. Fifty patients diagnosed with cervical carcinoma prospectively underwent magnetic resonance (MR) imaging before and after vaginal opacification (VO) with a mixture of 25 ml saline and 25 ml barium. T2-weighted (T2W) TSE images in axial and sagittal planes were compared before and after vaginal opacification. Dynamic T1W images in sagittal and fat-suppressed T1W images in transverse planes were also evaluated after intravenous contrast administration. Involvement of vaginal wall, lumen, and fornices; parametrium; rectum; and bladder were noted. Changes in local tumor staging and in treatment planning were also assessed after vaginal opacification. MR results were later compared with surgical pathological findings. Twenty-eight patients who went through surgical staging were included in the study. VO did not change any of the MR interpretations in 14 patients (50%). Correct staging was achieved with T2W TSE images with and without VO (in sagittal and transverse planes) in 78.5% and 50% of the patients, respectively. VO correctly lowered staging in seven and increased it in three patients compared with sagittal standard T2W images. Treatment planning was also changed in four (14%) of these patients. When overall accuracy of MR staging to indicate the appropriate treatment was evaluated, patients would have received the proper treatment in 90% and 79% of the cases when only T2W sagittal images with and without VO were evaluated, respectively. Dynamic gradient-echo images in sagittal planes and postcontrast T1W images in transverse planes evaluated with T2W series after VO, accomplished correct staging in 23 (82%) of the patients. MRI staging in early cervical cancer may be difficult and overestimated, especially if the tumor is slightly extended into the proximal vagina. Use of vaginal contrast medium is an easy, well-tolerated, and effective

    A heterologous antiserum for human cervical squamous cell carcinoma was prepared and specificity determined by Ouchterlony immunodiffusion and immunofluorescence studies. With this antiserum, a tumor antigen was purified from human cervical squamous cell carcinoma tissue. The specificities of the antigen and the antiserum were then re-examined by a radioimmunoassay method using 125 I-labeled purified antigen. Although normal cervical tissue extract showed a moderate cross-reactivity in the radioimmunoassay, the circulating antigen activity could not be detected in normal women or in several patients with other carcinomas, whereas 27 of 35 patients with cervical squamous cell carcinoma showed detectable serum antigen activity. All patients with advanced stages of cervical squamous cell carcinoma showed detectable antigen levels. These results indicate that there is a quantitative abnormality, at least, of this tumor antigen in patients with cervical squamous cell carcinoma and that the radioimmunoassay for the antigen is a potentially useful tool in clinical care

    Recently, magnetic resonance imaging (MRI) and transrectal or transvaginal ultrasound (TRUS, TVUS) had an important place in imaging techniques of cervical carcinomas and raise the question of modifying the imaging strategies. For the diagnosis of primitive tumor, those techniques cannot take the place of clinical examination and gross examination. In the assessment of parametrial involvement, TRUS which has better accuracy than clinical examination, and MRI which is considered as the most accurate technique, have an important role to play. In the follow-up and the detection of recurrences, MRI is actually considered as the best imaging technique. The authors, according to recent data in literature and their own experience, present basic concepts of imaging strategies for staging and follow-up of cervical carcinomas [fr

    A group of patients with clinical stage I or II squamous cell cervical carcinoma have been examined using a 1.5-T magnet. Of these, six have had radical hysterectomy (by April 1986), providing specimens for pathologic correlation. In this preliminary group of patients, MR imaging gave a more accurate assessment of primary tumor extent than did clinical staging. In three of six patients, the disease was underestimated clinically at examination under anesthesia. These patients would have been managed with preoperative radiation rather than surgery alone if the investigative MR imaging information had been used in treatment planning. CT examinations of these patients did not contribute useful information for patient management. Preoperative MR imaging has the potential to alter patient treatment in early cervical carcinoma

    Eighty-nine patients with previously untreated invasive carcinoma of the cervical stump were seen at Yale-New Haven Hospital from 1953 through 1977. This represented 9.4% of the carcinomas of the cervix seen during this time period. Eighty-five of the 89 patients (95.5%) had ''true'' cancers of the cervical stump diagnosed 2 years or more after subtotal hysterectomy, while 4 of the 89 patients (4.5%) had ''coincident'' cancers diagnosed within 2 years of the subtotal hysterectomy. All cervical cancers were staged by the F.I.G.O. classification. Patient characteristics, methods of management, failure sites and survival of patients with carcinoma of the cervical stump were compared to those patients with carcinoma in the intact uterus. Patients with cervical stump cancers were treated in a similar manner to those with carcinomas of the intact uterus, using a combination of external beam irradiation and intracavitary radium. The stump cancer patients had a similar stage distribution to the patients with cancers of the intact uterus but, on the average, they were older and received less irradiation. The patterns of failure were similar on a stage for stage basis, but the survival and disease-free survival for stump cancer patients were superior to those of the patients with carcinoma of the intact uterus

    Forty-nine patients aged {le} 45 years, with cervical carcinoma stage IB ({le} 3 cm) were treated with either primary radical surgery (n = 26), or intracavitary irradiation followed by radical surgery (n = 23). With primary surgery, ovarian function had been preserved in 15 of the 25 patients, who were alive and well. Seven of the primary surgery patients were irradiated postoperatively and 2 others with a central recurrence were cured by irradiation. One other patient, who was not irradiated postoperatively, had an intestinal metastasis and died of the disease. If any of the adverse prognostic factors (as reported in the literature) had been considered as an indication for postoperative irradiation, 17 patients instead of 7 would have been irradiated after primary radical surgery. In the comparable group of 23 patients treated by intracavitary irradiation and radical surgery (and in 4 cases postoperative irradiation as well) there was no recurrence. There was no significant statistical difference between the treatment results in the cesium + surgery group and those who underwent primary radical surgery. Young patients with early cervical carcinoma without prognostic indicators for postoperative irradiation can benefit from primary radical surgery, because their ovarian function can be preserved.

    To compare three-dimensional (3D) T2-weighted turbo spin-echo (TSE) with multiplanar two-dimensional (2D) T2-weighted TSE for the evaluation of invasive cervical carcinoma. Seventy-five patients with cervical carcinoma underwent MRI of the pelvis at 3.0 T, using both 5-mm-thick multiplanar 2D (total acquisition time = 12 min 25 s) and 1-mm-thick coronal 3D T2-weighted TSE sequences (7 min 20 s). Quantitative analysis of signal-to-noise ratio (SNR) and qualitative analysis of image quality were performed. Local-regional staging was performed in 45 patients who underwent radical hysterectomy. The estimated SNR of cervical carcinoma and the relative tumour contrast were significantly higher on 3D imaging (P < 0.0001). Tumour conspicuity was better with the 3D sequence, but the sharpness of tumour margin was better with the 2D sequence. No significant difference in overall image quality was noted between the two sequences (P = 0.38). There were no significant differences in terms of the diagnostic accuracy, sensitivity, and specificity of parametrial invasion, vaginal invasion, and lymph node metastases. Multiplanar reconstruction 3D T2-weighted imaging is largely equivalent to 2D T2-weighted imaging for overall image quality and staging accuracy of cervical carcinoma with a shorter MR data acquisition, but has limitations with regard to the sharpness of the tumour margin. circle 3D T2-weighted MR sequence is equivalent to 2D for cervical carcinoma staging.

    Full Text Available Background: Pelvic lymph node metastasis (LNM is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs, unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People′s Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI, depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases. Pelvic LNM (P = 0.00 was significantly correlated with recurrence. Pelvic LNM (P = 0.00, the number of positive pelvic LNs (P = 0.04 and a single group versus multiple groups of pelvic LNM (P = 0.03 had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00, depth of cervical stromal invasion (P = 0.00 and parametrial invasion (P = 0.03 were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma.

    In uterine cervical canal carcinoma, the current clinical FIGO criteria often fail not only to differentiate stage IA2 from stage IB but also to demonstrate possible parametrial involvement. Moreover, the analysis of tumor volume and of the depth of neoplastic stromal invasion is not very reliable. The authors investigated MR accuracy in the definition of such variables: to this purpose, 24 patients with histologically confirmed endocervical adenocarcinoma were submitted to MRI, which was performed with an 0.5-T superconductive magnet. Sagittal and oblique transverse or sometimes coronal SE images, oriented so as to be perpendicular to longitudinal cervical major axis were obtained with T2 weighting (TR 1800 ms, TE 25-90 ms). MR data were correlated with pathologic findings. MR accuracy in demonstrating parametrial involvement was 92%, its sensitivity was 86% and specificity 97%. Volumetric MR data showed a high correlation (r = 0.970) with those derived from pathologic findings. In 92% of cases stromal invasion exceeded 5 mm. MRI, thanks to its high accuracy, should be included in diagnostic pretreatment protocols, even though FIGO criteria do not require it yet, especially in the presence of an endocervical adenocarcinoma. Moreover, the accurate definition of tumor volume can allow less extensive surgery with the same survival rates and fewer complications, which are frequently observed after radical hysterectomy.

    To determine MR imaging features and staging accuracy of neuroendocrine carcinomas (NECs) of the uterine cervix with pathological correlations. Twenty-six patients with histologically proven NECs, 60 patients with squamous cell carcinomas (SCCs), and 30 patients with adenocarcinomas of the uterine cervix were included. The clinical data, pathological findings, and MRI findings were reviewed retrospectively. MRI features of cervical NECs, SCCs, and adenocarcinomas were compared, and MRI staging of cervical NECs was compared with the pathological staging. Cervical NECs showed a higher tendency toward a homogeneous signal intensity on T2-weighted imaging and a homogeneous enhancement pattern, as well as a lower ADC value of tumour and a higher incidence of lymphadenopathy, compared with SCCs and adenocarcinomas (P < 0.05). An ADC value cutoff of 0.90 x 10{sup -3} mm{sup 2}/s was robust for differentiation between cervical NECs and other cervical cancers, with a sensitivity of 63.3 % and a specificity of 95 %. In 21 patients who underwent radical hysterectomy and lymphadenectomy, the overall accuracy of tumour staging by MR imaging was 85.7 % with reference to pathology staging. Homogeneous lesion texture and low ADC value are likely suggestive features of cervical NECs and MR imaging is reliable for the staging of cervical NECs. (orig.)

    Full Text Available A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP and the American Society for Clinical Pathology (ASCP in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG. The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV testing, as well as possible future screening strategies.

    Biopsy is the technique of choice for the definitive diagnosis of endometrial carcinoma. Since lymphatic tumor spread has been demonstrated to depend on the degree of myometrial involvement, the definition of the latter with imaging techniques may significantly affect both pfognosis and therapy. We investigated, by means of MR imaging at 0.5 T, 14 patients with endometrial carcinoma, to assess both tumor stage and myometrial involvement. FIGO staging system was employed, and M parameter evaluated (M0= no myometrial involvement; M1involvement confined to the inner third; M2= Involvement confined to the middle third; M3= involvement of the whole myometrium). Another parameter was the characteristic high signal of the tumor on PD and T2W images. The patients were then operated and MR information was correlated with surgical findings. Overall diagnostic accuracy of MR imaging was 85.7% in tumor staging, and 92.2% in defining M parameter. Tumor spread into adnexa and into cervical canal was poorly demonstrated by MR imaging

    An accurate preoperative assessment of cervical lymph node status is a prerequisite for individually tailored cancer therapies in patients with oral squamous cell carcinoma. The detection of malignant spread and its treatment crucially influence the prognosis. The aim of the present study was to analyze the different staging modalities used among patients with a diagnosis of primary oral squamous cell carcinoma between 2008 and 2015. An analysis of preoperative staging findings, collected by clinical palpation, ultrasound, and computed tomography (CT), was performed. The results obtained were compared with the results of the final histopathological findings of the neck dissection specimens. A statistical analysis using McNemar's test was performed. The sensitivity of CT for the detection of malignant cervical tumor spread was 74.5%. The ultrasound obtained a sensitivity of 60.8%. Both CT and ultrasound demonstrated significantly enhanced sensitivity compared to the clinical palpation with a sensitivity of 37.1%. No significant difference was observed between CT and ultrasound. A combination of different staging modalities increased the sensitivity significantly compared with ultrasound staging alone. No significant difference in sensitivity was found between the combined use of different staging modalities and CT staging alone. The highest sensitivity, of 80.0%, was obtained by a combination of all three staging modalities: clinical palpation, ultrasound and CT. The present study indicates that CT has an essential role in the preoperative staging of patients with oral squamous cell carcinoma. Its use not only significantly increases the sensitivity of cervical lymph node metastasis detection but also offers a preoperative assessment of local tumor spread and resection borders. An additional non-invasive cervical lymph node examination increases the sensitivity of the tumor staging process and reduces the risk of occult metastasis. Copyright © 2016 European

    To evaluate if preoperative radiotherapy influences course of operation (radical hysterectomy and lymphadenectomy) and postoperative period in series of stage IB-IIA cervical carcinomas. Retrospective comparative study was performed. During the study we analyzed 101 case histories of patients who underwent radical type II hysterectomy with lymphadenectomy in Kaunas University of Medicine Hospital and Kaunas Hospital of Oncology between 1995 and 2002. Mean operation time was shorter, hemoglobin and hematocrit values after operation were better, stay in hospital was longer, demand for narcotic analgetics was bigger, function of ovaries was maintained more rarely (p 0.05). In our study, preoperative radiotherapy did not seem to complicate course of radical hysterectomy. (author)

  15. Large Conization and Laparoendoscopic Single-Port Pelvic Lymphadenectomy in Early-Stage Cervical Cancer for Fertility Preservation

    2013-01-01

    Full Text Available Fertility preservation in early-stage cervical cancer is a hot topic in gynecologic oncology. Although radical vaginal trachelectomy (RVT is suggested as a fertility preserving approach, there are some serious concerns like cervical stenosis, second trimester loss, preterm delivery in survivors, and lack of residual tumor in the majority of the surgical specimens. Therefore, less radical surgical operations have been proposed in early-stage cervical carcinomas. On the other hand, single-incision laparoscopic surgery (SILS is an evolving endoscopic approach for minimal access surgery. In this report, we present a case with early-stage cervical cancer who wishes to preserve fertility. We successfully performed single-port pelvic lymphadenectomy and large conization to preserve fertility potential of the patient. We think that combination of less radical approach like conization and single-port pelvic lymphadenectomy might be less minimally invasive and is still an effective surgical approach in well-selected cases with cervical carcinomas. Incorporation of single-port laparoscopy into the minimally invasive fertility sparing management of the cervical cancer will improve patients outcome with less complications and better cosmesis. Further studies are needed to reach a clear conclusion.

    We retrospectively evaluated 41 patients with metastatic cervical tumors from unknown primary sites at the Hyogo College of Medicine between 1997 and 2007. The N stage classification of cervical lymph nodes was: N1 in 3 cases, N2a in 10 cases, N2b in 10 cases, N2c in 4 cases, and N3 in 14 cases. The histopathological diagnoses of cervical lymph node were: squamous cell carcinoma in 33 cases, adenocarcinoma in 5 cases, undifferentiated carcinoma in 2 cases, and papillary carcinoma in 1 cases. Primary tumor sites were: tonsil in 5 cases, esophaguses in 2 cases, hypopharynxies in 2 cases, and thyroid, oral floor, submandibular gland, lung, gastric and colon in 1 case each. The useful tests were gastric endoscope, positron emission tomography-computed tomography (PET-CT), and blind biopsy of tonsil. We treated 24 of the 41 patients. Therapies were: neck dissection with postoperative radiation therapy in 11 cases, neck dissection alone in 1 case, only radiation or chemoradiation therapy alone in 8 cases, and chemotherapy alone in 4 cases. The 5-year survival rate was 40.1% in all cases and 81.5% in cases who underwent neck dissection. (author)

    Possible deep (more than an inner third of the uterine wall) myometrial invasion and cervical extension of endometrial carcinoma were evaluated prospectively using magnetic resonance (MR) and transabdominal real-time sonography (US) in 20 and 10 patients, respectively. The data obtained from these examinations were compared with hysterosalpingography (HSG) and clinical modalities including hysteroscopy, sounding and histopathologic findings after surgery. The concordance of outlining cervical extension was between MR and hysteroscopy 85 per cent, and between US and hysteroscopy 50 per cent. Deep myometrial tumor invasion was suggested in 4/10 patients by US and in 6/20 by MR, and was confirmed in all but one in each group at histologic examination of the resected uterus. There were no false negative US or MR examinations. Transabdominal US did not prove accurate in defining local endometrial carcinoma (distinguishing between stages I and II), but it may be used as an additional tool in revealing myometrial invasion. MR, however, seems to refine the delineation of uterine tumor growth. (orig.)

    Suppressor of fused is essential for the maximal activation of Sonic Hedgehog signaling in development and tumorigenesis. However, the role of Sufu in cervical carcinoma remains unknown. Here, we report new findings of Sufu in regulating the epithelial-to-mesenchymal transition through the FoxM1 transcriptional modulation by 14-3-3ζ protein in cervical carcinoma. Sufu is overexpressed in cervical squamous cell carcinoma and its level in clinical tumor tissues is positively correlated with 14-3-3ζ. Functionanlly, siSufu remarkably prevents the cancer cell migration and invasion. We further demonstrate that the transcriptional activity of Sufu is increased by FoxM1, of which stability is promoted by 14-3-3ζ. Knockdown FoxM1 decreases the invasion of SiHa cells and reconstitution of Sufu rescues the invasion of these cells.Finally, overexpression of Sufu is significantly associated with differentiation grade, FIGO stage, Depth of stromal invasion and vascular cancer embolus. Our findings highlight a novel role for Sufu in cervical carcinogenesis. PMID:29371981

    2005-01-01

    Full Text Available Purpose: In clinical practice, radiation therapy often fails in cervical carcinoma stage IIIB and there is a need to develop a predictive assay for prognosis of radiation treatment outcome in cancer patient. We have attempted to evaluate the relevance of changes in Membrane Fluidity (MF and associated apoptotic cell death in cervical cancer cells after first fractionated dose of radiation therapy to treatment outcome of stage IIIB cervical carcinoma patients. Materials and Methods: Biopsies of 15 patients with histologically proven cervix cancer were collected from the patients before and 24 h after first fractionated radiation dose of 2 grays (Gy. Cell suspension made in Dulbecco′s Modified Eagle′s Medium (DMEM were used for further investigations and cell suspension of cervix cancer patient were used to measure MF by fluorescence polarization method and apoptotic index (AI was determined by Tdt dUTP Nucleotide End Labeling (TUNEL assay. Results: A substantial increase in MF and AI was observed in cervical cancer cells irradiated ex vivo . A significant correlation ( P < 0.001 was found between the changes in AI after first fractionated dose of radiotherapy and treatment outcome of patients. No significant correlation ( P > 0.1 was detected between changes in MF and treatment outcome of patients. Conclusion: Preliminary results showed significant change in MF and a marked increase in percentage apoptosis of cervix cancer cells irradiated ex vivo . The changes in AI after first fractionated dose of radiotherapy in cervical carcinoma patients may provide a predictor of prognosis for radiotherapy in uterine cervical carcinoma patients.

    Radiotherapy in cervical carcinoma patients is frequently followed by severe intestinal injuries which serve as prerequisites for the penetration of endotoxins of intestinal microflora into the systemic circulation. Peculiarities of possible development of endotoxemia were studied in 45 women with cervical carcinoma (Stages 2, 3). Radiotherapy was performed by routine methods (long-focus irradiation with subsequent intracavitary irradiation, or simultaneous long-focus and intracavitary irradiation). The presence of bacterial endotoxins in the patients blood was revealed by the testing of the lethal effect after intraperitoneal administration of the examined blood (0.1 ml) to random-bred albino mice simultaneously with actinomycin D(10 ..mu..g/mouse) that sharply increases the sensitivity of animals to a toxic effect of endotoxins. It has been established that involvement of the intestine in irradiation is followed by endotoxemia regardless of radiotherapeutic methods. The degree of severity of endotoxemia developing in the first half of a radiotherapeutic course depends on a radiation dose. On reaching a certain level, endotoxemia preserves its severity up to the end of irradiation and at early time after its completion.

    The aim of this study was to analyze the relationship between serum squamous cell carcinoma antigen (SCC-Ag) and the clinicopathological features of cervical squamous cell carcinoma. The value of SCC-Ag and computed tomography (CT) for predicting lymph node metastasis (LNM) was evaluated. A total of 197 patients with International Federation of Gynecology and Obstetrics stages IB to IIA cervical squamous cell carcinoma who underwent radical surgery were enrolled in this study. The SCC-Ag was measured, and CT scans were used for the preoperative assessment of lymph node status. Increased preoperative SCC-Ag levels were associated with International Federation of Gynecology and Obstetrics stage (P = 0.001), tumor diameter of greater than 4 cm (P 4 cm (P = 0.001, OR = 4.019), and greater than one half stromal infiltration (P = 0.002, OR = 3.680) as independent factors affecting SCC-Ag greater than or equal to 2.35 ng/mL. In the analysis of LNM, SCC-Ag greater than or equal to 2.35 ng/mL (P < 0.001, OR = 4.825) was an independent factor for LNM. The area under the receiver operator characteristic curve (AUC) of SCC-Ag was 0.763 for all patients, and 0.805 and 0.530 for IB1 + IIA1 and IB2 + IIA2 patients, respectively; 2.35 ng/mL was the optimum cutoff for predicting LNM. The combination of CT and SCC-Ag showed a sensitivity and specificity of 82.9% and 66% in parallel tests, and 29.8% and 93.3% in serial tests, respectively. The increase of SCC-Ag level in the preoperative phase means that there may be a pathological risk factor for postoperative outcomes. The SCC-Ag (≥2.35 ng/mL) may be a useful marker for predicting LNM of cervical cancer, especially in stages IB1 and IIA1, and the combination of SCC-Ag and CT may help identify patients with LNM to provide them with the most appropriate therapeutic approach.

    The methods and results of treatment for cancer of the cervical esophagus differ from those for cancer of the thoracic esophagus. Our objective was to retrospectively review the outcome for cervical esophageal cancer patients treated with radiotherapy. Twenty-seven patients with carcinoma of the cervical esophagus treated with definitive radiotherapy from 1988 to 2002 were enrolled in the study. Clinical stage (UICC 1997) was stage I in five, II in six, III in 12 and IV in four. Concurrent head and neck malignancy was found in six patients (22%). The mean radiation dose was 66 Gy. Concurrent chemotherapy (cisplatin and 5-fluorouracil) was performed in 23 patients. The actuarial overall survival rates at 1, 3 and 5 years were 55.6%, 37.9% and 37.9%, respectively, with a median survival of 13.9 months. In the patients with stage I, the 3-year and 5-year survival rates were 75% and 75%, respectively. With univariate analysis, only two of the possible prognostic factors were found to actually influence survival: performance status (p<0.01) and tumor length (p<0.01). The survival of patients with cervical esophageal cancer remains poor. It is thought that organ preservation is possible by definitive chemoradiation for early cancer

    Squamous cell carcinoma antigen (SCC-A) in serum was serially measured during follow-up of 96 squamous cell carcinoma patients (75 head and neck cancers and 21 uterine cervical cancers), treated with radiotherapy. In 27 of the patients with head and neck cancer and in 12 of those with cervical cancer SCC-A had also been measured before radiotherapy. In this head and neck carcinoma group, the median level of SCC-A was 1.3 (95% CI: 1.2-1.9) ng/ml before radiotherapy and 1.4 (CI: 1.1-1.5) ng/ml after radiotherapy. In the cervical carcinoma group, the median SCC-A decreased significantly (p<0.001) from a pretreatment value of 7.5 (CI: 3.8-26.3) ng/ml to a posttreatment value of 0.9 (CI:<0.5-1.8) ng/ml. In the total group of 75 head and neck cancers 21 relapses occurred and in 4 of these the relapse was detected at a clinically silent stage by an elevation of serum SCC-A. The same was true for 4 of the 9 relapses that occurred in the total group of uterine cervical cancer. The study suggests that serum SCC-A may be useful for posttreatment monitoring of patients with uterine cervix cancer while its value in head and neck cancer probably is more marginal. (orig.)

    To date, cervical carcinoma complicated with Cushing's syndrome were all diagnosed as small cell carcinoma histo- logically, but not adenosquamous carcinoma. Here the authors present the diagnosis, management, and prognosis of a case of melanocytic cervical adenosquamous carcinoma complicated with Cushing's syndrome. A 28-year-old woman was admitted with the chief complaint of post-coital bleeding for one month. Gynecological examination revealed a nodular yellowish-pigmented vegetation (6x5 cm) on the cervix. Laboratory findings proved the diagnosis of Cushing's syndrome. Histopathological diagnosis showed the adenosquamous carcinoma with melanoma differentiation. Immunohistochemical stainings for melanoma A and anti- adrenocorticotropic hormone (ACTH) were positive in the majority of the tumor cells, which indicated that this melanocytic cervical carcinoma lesion was the source of ectopic ACTH production resulting in Cushing's syndrome. This is a unique case of a rare type of cervical carcinoma.

    , ionizing radiation did not stimulate p53 accumulation or apoptosis in these cells. Cervical epithelial cells containing the intact HPV 16 genome also exhibited hypoxia induced apoptosis. Hypoxia stimulated p53 induction but not apoptosis in cell lines derived from human cervical squamous cell carcinomas, indicating that these cell lines have acquired further genetic alterations independent of p53 which reduced their apoptotic sensitivity to hypoxia. Furthermore, E6 and E7 infected cervical epithelial cells subjected to multiple rounds of hypoxia followed by aerobic recovery achieved resistance to hypoxia induced apoptosis, indicating that hypoxia could directly select for cells with diminished apoptotic sensitivity. In situ, hypoxia and apoptosis were found to co-localize in tumors of patients with advanced clinical stage. Conclusion: Expression of viral oncoproteins in human cervical epithelial cells can increase their sensitivity to hypoxia-induced apoptosis. Hypoxia can select for variants that have lost their apoptotic potential and hypoxia correlates spatially with apoptosis in human cervical carcinoma biopsies. Therefore, these results implicate a role for hypoxia-mediated selection in human tumor progression and can in part explain the aggressiveness of cervical carcinomas with low p0 2 values

    Purpose: High-dose-rate (HDR) brachytherapy is in wide use for curative treatment of cervical cancer. The American Brachytherapy Society has recommended that the individual fraction size be <7.5 Gy and the range of fractions should be four to eight; however, many fractionation schedules, varying from institution to institution, are in use. We use 9 Gy/fraction of HDR in two to five fractions in patients with carcinoma of the uterine cervix. We found that our results and toxicity were comparable to those reported in the literature and hereby present our experience with this fractionation schedule. Methods and Materials: A total of 121 patients with Stage I-III carcinoma of the uterine cervix were treated with HDR brachytherapy between 1996 and 2000. The total number of patients analyzed was 113. The median patient age was 53 years, and the histopathologic type was squamous cell carcinoma in 93% of patients. The patients were subdivided into Groups 1 and 2. In Group 1, 18 patients with Stage Ib-IIb disease, tumor size <4 cm, and preserved cervical anatomy underwent simultaneous external beam radiotherapy to the pelvis to a dose of 40 Gy in 20 fractions within 4 weeks with central shielding and HDR brachytherapy of 9 Gy/fraction, given weekly, and interdigitated with external beam radiotherapy. The 95 patients in Group 2, who had Stage IIb-IIIb disease underwent external beam radiotherapy to the pelvis to a dose of 46 Gy in 23 fractions within 4.5 weeks followed by two sessions of HDR intracavitary brachytherapy of 9 Gy each given 1 week apart. The follow-up range was 3-7 years (median, 36.4 months). Late toxicity was graded according to the Radiation Therapy Oncology Group criteria. Results: The 5-year actuarial local control and disease-free survival rate was 74.5% and 62.0%, respectively. The actuarial local control rate at 5 years was 100% for Stage I, 80% for Stage II, and 67.2% for Stage III patients. The 5-year actuarial disease-free survival rate was 88.8% for

    Human papillomavirus (HPV)-associated cervical carcinoma is preceded by stages of cervical intra-epithelial neoplasia (CIN) that can variably progress to malignancy. Understanding the different molecular processes involved in the progression of pre-malignant CIN is critical to the development of improved predictive and interventional capabilities. We tested the role of regulators of transcription in both the development and the progression of HPV-associated CIN, performing the most comprehensive genomic survey to date of DNA methylation in HPV-associated cervical neoplasia, testing ~2 million loci throughout the human genome in biopsies from 78 HPV+ women, identifying changes starting in early CIN and maintained through carcinogenesis. We identified loci at which DNA methylation is consistently altered, beginning early in the course of neoplastic disease and progressing with disease advancement. While the loss of DNA methylation occurs mostly at intergenic regions, acquisition of DNA methylation is at sites involved in transcriptional regulation, with strong enrichment for targets of polycomb repression. Using an independent cohort from The Cancer Genome Atlas, we validated the loci with increased DNA methylation and found that these regulatory changes were associated with locally decreased gene expression. Secondary validation using immunohistochemistry showed that the progression of neoplasia was associated with increasing polycomb protein expression specifically in the cervical epithelium. We find that perturbations of genomic regulatory processes occur early and persist in cervical carcinoma. The results indicate a polycomb-mediated epigenetic field defect in cervical neoplasia that may represent a target for early, topical interventions using polycomb inhibitors. PMID:27557505

    The standard treatment for women with early-stage cervical cancer (IA2-IB1) remains radical hysterectomy with pelvic lymphadenectomy. In select patients interested in future fertility, the option of radical trachelectomy with pelvic lymphadenectomy is also considered a viable option. The possibility of less radical surgery may be appropriate not only for patients desiring to preserve fertility but also for all patients with low-risk early-stage cervical cancer. Recently, a number of studies have explored less radical surgical options for early-stage cervical cancer, including simple hysterectomy, simple trachelectomy, and cervical conization with or without sentinel lymph node biopsy and pelvic lymph node dissection. Such options may be available for patients with low-risk early-stage cervical cancer. Criteria that define this low-risk group include: squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma, tumor size <2 cm, stromal invasion <10mm, and no lymph-vascular space invasion. In this report, we provide a review of the existing literature on the conservative management of cervical cancer and describe ongoing multi-institutional trials evaluating the role of conservative surgery in selected patients with early-stage cervical cancer.

    The aim of diagnostic imaging is not so much the detection of cervical carcinoma, but the evaluation of its stage. In view of this the aim of this study included: 1) comparison of MR results with the results of histological examinations after operations with reference to the dimensions of cervical carcinoma; 2) assessment of the sensitivity and specificity of MRl in the evaluation of parametrium infiltration; 3) analysis of the sensitivity and specificity of MRI in the evaluation of infiltration of the vagina and uterus; 4) assessment of the usefulness of this method in the detection of metastases to lymph nodes.The material consisted of pelvic MRI, obtained with 2T Elscint unit in 15 patients with cervical carcinoma, aged 37 to 73 years. All patients underwent surgical treatment within 30 days after MR. During the MR examination the following sequences were performed: SE (spin echo) T1 (longitudinal relaxation time) in axial projection before administration of gadolinium (Gd-DTPA); SE T1 in axial, frontal and sagittal projections after contrast injection and FSE (fast spin echo) T2 (transversal relaxation time) in axial, frontal and sagittal projections.1) in the assessment of cervical carcinoma dimensions MRI results are highly concordant with the results of postoperative histological examination (p = 0. 9389); 2) in the assessment of parametrium infiltration sensitivity and specificity of MRI are 75% and 100%, respectively; 3) in the assessment of the infiltration of the vagina and uterine corpus the sensitivity and specificity of MRI imaging were respectively 100% and 85%; 100% and 100%; 4) in the detection of lymph node metastases MRI sensitivity was 67% and its specificity 100%. In patients with cervical carcinoma MRI is a valuable method for the assessment of tumour dimensions, parametrium infiltration, infiltration of the vagina and uterine corpus.(author)

    The authors evaluated the feasibility of a laparoscopic sentinel lymph node (SN) procedure with combined radioisotopic and patent blue labeling in patients with cervical carcinoma. Thirteen women (median age, 52.5 years) with cervical carcinoma (Stage Ia2 in 1 patient, Stage Ib1 in 10 patients, Stage Ib2 in 1 patient, and Stage IIa in 1 patient) underwent a laparoscopic SN procedure using an endoscopic gamma probe after both radioactive isotope and patent blue injections. After the procedure, all patients underwent complete laparoscopic pelvic lymphadenectomy and either laparoscopic radical hysterectomy (eight patients) or the Schauta-Amreich operation (five patients). SNs (mean, 1.7 SNs per patient; range, 1-3 SNs per patient) were identified in 12 of 13 patients. A median of 10.5 pelvic lymph nodes per patient (range, 4-17 pelvic lymph nodes per patient) were removed. No lymph node involvement was detected in SNs with hematoxylin and eosin staining. Immunohistochemical studies identified four metastatic SNs in two patients, with micrometastases in two SNs from the first patient and isolated tumor cells in two SNs from the second patient. No false-negative SN results were obtained. The results of this study suggest that SN detection with a combination of radiocolloid and patent blue is feasible in patients with cervical carcinoma. The combination of laparoscopy and the SN procedure permitted minimally invasive management of early-stage disease. Copyright 2003 American Cancer Society.

    Metalloproteinase activities of a disintegrin and metalloproteinase 17 (ADAM17), amphiregulin (AREG), extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinases (MMPs) are involved in tumor biology. In patients with uterine cervical carcinoma, the expression and prognostic significance of ADAM17 remain to be fully elucidated. The expression of ADAM17, AREG, EMMPRIN, phospho-epidermal growth factor receptor (p-EGFR), phospho-extracellular signal-regulated kinase (p-ERK), MMP-2, and MMP-9 was assessed by immunohistochemistry and/or Western blotting from cervical carcinoma cell lines, SiHa and HeLa cells, and cervical carcinoma tissues. AREG activity was measured by ELISA assay. The correlation of ADAM17, AREG, EMMPRIN, and MMP-9 expression with patients' survival rates was assessed by Kaplan-Meier and Cox regression analyses. RNA interference (RNAi) experiment was performed using small interfering mRNA to ADAM17 and EMMPRIN. ADAM17, EMMPRIN, and MMP-9 protein content was overexpressed in cervical carcinoma tissues compared with normal cervical tissues (P EMMPRIN, and MMP-9 was significantly associated with stages, lymph node metastasis, differentiation, and parametrium invasion (P EMMPRIN, and MMP-9 was significantly correlated with short progression-free survival and overall survival (P EMMPRIN, p-EGFR, p-ERK, MMP-2, and MMP-9 proteins in SiHa and HeLa cells. ELISA assay revealed that AREG activity was stimulated by ADAM17 and was reversed by ADAM17 RNAi in SiHa and HeLa cells. Our data suggest that the increased expression of ADAM17 in cervical cancer is significantly associated with aggressive progression and poor prognosis. ADAM17 may be a molecular marker for predicting the progression and prognosis in cervical cancer.

    We examined a large series of biopsy-proven invasive cervical cancers with surgical staging and HPV re-testing to estimate the relevance of HPV-negative cervical cancers in a Caucasian population. We prospectively collected smears from 371 patients with a biopsy-proven diagnosis of cervical cancer for HC2 testing of high-risk HPV (HR-HPV). In HC2-negative cases, smears and paraffin embedded tissue blocks underwent additional HPV genotyping. HC2 tests showed 31/371 cases (8.8%) had negative findings. Surgical staging showed that 21/31 HC2-negative cases (68%) were not cervical cancer. Overall, 340/350 cases of primary cervical cancer confirmed by surgical staging tested HC2 positive (97.2%). Non-high-risk HPV subtypes were detected in five cases (one HPV-53, one HPV-70, and three HPV-73) and high-risk subtypes in four patients with HC2-negative cervical cancer (two HPV 16 and two HPV-18). The remaining case, a primary undifferentiated carcinoma of the uterine cervix, tested negative for HPV-DNA with all tests. The main explanation for HPV-negative cervical cancer was a false diagnosis, followed by cancers associated with non-HR-HPV types, and false-negative HR-HPV results. Truly HPV negative seem to be very rare in Caucasian populations. Retrospective analyses without surgical staging may overestimate the proportion of HPV negative cervical cancers.

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate. Of 172 post-operative cases, 20.8% (11/53) of those with lymph node metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymph node metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.).

    The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 55-year-old postmenopausal woman, gravida 5 para 5, with past medical history significant for hypertension, presented to the emergency department with profuse vaginal bleeding and a hemoglobin level of 9 g/dL. The biopsy from an irregular 6-cm cervical mass was consistent with moderately differentiated cervical squamous cell carcinoma. The physical examination did not reveal vaginal or parametrial extension of the tumor. Pelvic magnetic resonance imaging disclosed the known carcinoma, as well as a 9.2 × 7.7 × 6.7 cm anterior uterine fibroid (Fig 1). A staging positron emission tomography scan was negative for metastatic disease. After blood transfusion and vaginal packing, the patient was referred to discuss the immediate management of her newly diagnosed bleeding bulky cervical cancer. In the absence of parametrial or vaginal extension and in the absence of lymph node metastasis (both on clinical examination and imaging), she was classified as having International Federation of Gynecology and Obstetrics stage IB2 disease.

    Purpose: To provide longitudinal data on urologic morbidity after radiotherapy and brachytherapy for cervical carcinoma. Methods and Materials: Five-year longitudinal urologic morbidity data were recorded from 177 consecutive patients of median age 59 years (range: 22-86 years) with cervical carcinoma receiving radiotherapy with curative intent at the Copenhagen University Hospital, Denmark. FIGO stages (%) were as follows: Stage I (15), Stage II (30), Stage III (54), and Stage IV (1). Late morbidity was calculated as cumulative incidence based on actuarial estimates. Results: The 5-year cumulative incidence based on actuarial estimates of urologic morbidity Grades 1 + 2 + 3, Grades 2 + 3, and Grade 3 were 62%, 32%, and 5%, respectively. Frequencies of urologic morbidity in the 54 recurrence-free survivors at the end of follow-up indicated some reversibility in the case of Grades 1 and 2 morbidity. Conclusion: With the longitudinal design used in the present study, a rate of mild and moderate morbidity higher than that found in most of the previously reported literature was observed, giving cause for concern and underlining the importance of further longitudinal studies on this subject, specifically studies that relate to the background urologic morbidity in the female population, as well as to the fact that urologic morbidity might regress

    The prognostic factors of thoracic esophageal squamous carcinoma with cervical lymph nodal metastasis (CLNM) have not been specifically investigated. This study was performed to analyze the efficacy and prognostic factors of chemoradiotherapy for thoracic esophageal carcinoma with CLNM alone. From 2002 to 2011, 139 patients with inoperable esophageal cancer who underwent chemoradiotherapy at the Sun Yat-Sen University were retrospectively analyzed. Median radiation doses were 60 Gy (range: 50–68 Gy). Univariate and multivariate analyses were performed to compare overall survival (OS) and progression-free survival (PFS). The 1- and 3-year OS rates were 68.2% and 27.9%, respectively. The 1- and 3-year PFS rates were 51.9% and 20.1%, respectively. The multivariate analysis demonstrated that response to treatment, T stage, pathological grade, and laterality of cervical lymph nodal metastases were independent prognostic factors for thoracic esophageal carcinoma with CLNM. Concurrent chemoradiotherapy is an important and hopeful treatment option for patients with esophageal cancer with CLNM alone. Our study has revealed that response to treatment, T stage, pathological grade and laterality of cervical lymph nodal metastases are significant prognostic factors for long-term survival

    A patient with carcinoma of the cervical esophagus who visited a hospital with a complaint of difficulty in swallowing was reported. This patient was a 50 year old woman. It was 32 years since she had had external irradiation with x- ray over the neck for Basedow's disease at the age of 18. From the age of 30, she had had hypothyroidism and had used thyroid. She became aware of difficulty in swallowing in October, 1976. Then this symptom progressed gradually, and she also had hoarseness. She visited a hospital in August, 1977. At the first medical examination, pigmentation and atrophic changes in the neck induced by radiation were observed, and some lymphnodes with the size of a red bean were palpated. Esophageal roentogenography revealed circular and spiral type lesion in the cervical esophagus, which was 4 cm in length and had a clear boundary. Endoscopic examination revealed circular stenotic lesion. This lesion was diagnosed as squamous cell carcinoma by biopsy. Total of 3,000 rad of Linac x-ray was irradiated over the neck and the clavicle before operation. Operation findings revealed fibrosis, atrophy, and hardening of the thyroid gland caused by radiation. Carcinoma with the size 35 mm x 18 mm was limited to the cervical esophagus, and the degree of the progress was A/sub 2/, N/sub 2/, M/sub 0/ (Pl/sub 0/). Histological findings revealed moderately differentiated squamous cell carcinoma and its metastases to the right supraclaviclar lymphnodes. This carcinoma was diagnosed as radiation-induced carcinoma of the cervical esophagus, because this patient had had irradiation over the neck, locally marked atrophic changes and scar remained, and carcinoma occurred in the area which had been irradiated with x-ray.

    OBJECTIVE: To investigate the clinicopathological significance of podoplanin expression in the intratumoral stroma and neoplastic cells of early stage uterine cervical cancer. MATERIALS AND METHODS: A total of 143 patients with clinical stage I and IIA uterine cervical carcinomas underwent surgery between 2000 and 2007. Clinicopathological data and slides associated with these cases were retrospectively reviewed. Immunodetection of podoplanin expression in histologic sections of tissue microarray blocks was performed using the monoclonal antibody D2‐40. RESULTS: Expression of podoplanin was detected in neoplastic cells in 31/143 (21.6%) cases, with 29/31 (93.5%) of these cases diagnosed as squamous carcinoma. For all of the cases examined, the strongest signal for podoplanin expression was observed at the proliferating edge of the tumor nests. The rate of positive podoplanin expression for node‐positive cases was lower than that of node‐negative (18.9% vs. 22.6%, respectively). Furthermore, the rate of positive podoplanin expression in fatal cases was 10.5% vs. 21.6%, respectively. In 27/143 (18.8%) cases, podoplanin expression was detected in fibroblasts of the intratumoral stroma, and this expression did not correlate with patient age, clinical stage, tumor size, histologic type, depth of infiltration, or vascular involvement. Moreover, expression of podoplanin in intratumoral stroma fibroblasts was only negatively associated with nodal metastasis. A greater number of fatal cases was observed among negative intratumoral stroma fibroblasts (15.5% vs. 3.7%, respectively), although this difference was not significant. CONCLUSIONS: These preliminary results suggest that podoplanin may have a role in host‐tumor interactions and, as a result, may represent a favorable prognostic factor for squamous cervical carcinomas.

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objective is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomo-pathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%. For the dynamic GE sequence with intravenous gadolinium the sensitivity was 86.6%, the specificity 86.6%, the positive predictive value 86.6%, the negative predictive value 86.6% and the reliability 86.6%.

    The Feulgen DNA content in cells of uterine cervical carcinoma and that of its adjacent vaginal epithelium were measured by microfluorophotometry. The Feulgen DNA content in cells of uterine cervical carcinoma was increased and showed a greater variation of its DNA values compared with diploid cells. The Feulgen DNA content in cells of normal vaginal epithelium adjacent to cervical carcinoma was also increased compared with diploid cells in 6 out of 8 cases. The relativity between the cellular DNA content of cervical carcinoma and that of its adjacent normal vaginal epithelium was found. In 10 out of 14 cases of uterine cervical carcinoma, the mean value of cellular DNA content was increased after by therapuetic irradiation with 10 Gy. Radiation effects on the DNA content of vaginal epithelial cells were similar to those on the DNA content of carcinoma cells. (author)

    The evaluation of 5-year results obtained through 2 radiochemotherapy (RCT) regimens: cisplatin (CDDP), 20 mg/m × 5 days every 21 days; and CDDP, 40 mg/m per week in locally advanced cervical carcinoma. In this single-institution prospective randomized phase 3 study, 326 patients with stage IIB to IIIB squamous cell cervical carcinoma treated from March 2003 to March 2005 were included. One hundred sixty patients (49%) had stage IIB cervical carcinoma, 103 patients (31.5%) had stage IIIA cervical carcinoma, and 63 patients (19.5%) had stage IIIB cervical carcinoma. The patients were randomly assigned to 2 therapeutic arms: 164 patients in arm A (5 days) concurrent RCT with CDDP, 20 mg/m per day, days 1 to 5 every 21 days; and 162 patients in arm B (weekly), concurrent RCT with CDDP, 40 mg/m per day weekly. All patients were treated with external beam radiotherapy on the abdominopelvic region using 15-MV x-rays and a cervical boost using the x-rays arch technique or medium-dose-rate intracavitary brachytherapy. The 5-year survival rate obtained through the 2 RCT regimens are not statistically different, even if a tendency of superiority can be observed in the 5-day arm as far as overall survival (78% in arm A vs 72% in arm B; p = 0.14) and disease-free survival (73% in arm A and 69% in arm B; p = 0.09) are concerned. Five-year local relapse-free survival was significantly superior in the 5-day CDDP arm (87%) in comparison with the weekly CDDP arm (77%); p < 0.01. In the 5-day arm, local relapse rate was twice lower, 21/164 (13%), compared with the weekly arm, 40/162 (25%); p < 0.01). Distance failures were identical in the 2 therapeutic groups: 22/164 (13%) and 21/162 (13%), respectively, which shows the superiority of arm A regarding local control. The results of our study demonstrate that RCT with cisplatin, 20 mg/m × 5 days every 21 days, is superior regarding local efficacy and is less toxic compared with the weekly chemotherapy regimen.

    Aim Evidence supporting the recommendation to include chest radiography in the work-up of all cervical cancer patients is limited. We investigated the diagnostic value of routine chest radiography in cervical cancer staging. Methods All consecutive cervical cancer patients who presented at our tertiary referral center in the Netherlands (January 2006 – September 2013), and for whom ≥6 months follow-up was available, were included. As part of the staging procedure, patients underwent a routine two-directional digital chest radiograph. Findings were compared to a composite reference standard consisting of all imaging studies and histology obtained during the 6 months following radiography. Results Of the 402 women who presented with cervical cancer, 288 (71.6%) underwent chest radiography and had ≥6 months follow-up. Early clinical stage (I/II) cervical cancer was present in 244/288 (84.7%) women, while 44 (15.3%) presented with advanced disease (stage III/IV). The chest radiograph of 1 woman – with advanced pre-radiograph stage (IVA) disease – showed findings consistent with pulmonary metastases. Radiographs of 7 other women – 4 early, 3 advanced stage disease – were suspicious for pulmonary metastases which was confirmed by additional imaging in only 1 woman (with pre-radiograph advanced stage (IIIB) disease) and excluded in 6 cases, including all women with early stage disease. In none of the 288 women were thoracic skeletal metastases identified on imaging or during 6 months follow up. Radiography was unremarkable in 76.4% of the study population, and showed findings unrelated to the cervical carcinoma in 21.2%. Conclusion Routine chest radiography was of no value for any of the early stage cervical cancer patients presenting at our tertiary center over a period of 7.7 years. PMID:26135733

Materials and methods: Retrospective analysis of consecutive patients undergoing FDG PET-CT for staging of LACC in a single tertiary referral centre, between April 2008 and August 2011. Comparison was made between MRI and PET-CT findings and any subsequent impact on treatment intent or radiotherapy planning was evaluated. Results: Sixty-three patients underwent FDG PET-CT for initial staging of LACC. Major impact on management was found in 20 patients (32%), a minor impact in five (8%), and no impact in 38 (60%). In those patients where PET-CT had a major impact, 12 had more extensive local nodal involvement, five had occult metastatic disease, two had synchronous tumours, and one patient had equivocal lymph nodes on MRI characterized as negative. PET-positive nodal status at diagnosis was found to be a statistically significant predictor of relapse-free survival (p < 0.05). Conclusion: Staging FDG PET-CT has a major impact on the initial management of approximately one-third of patients with LACC by altering treatment intent and/or radiotherapy planning. PET-defined nodal status is a poor prognostic indicator. - Highlights: • Cervical carcinoma is one of the commonest cancers in women worldwide. • Locally advanced cervical carcinoma is usually treated with chemo-radiotherapy. • FDG PET-CT can have a major impact on management in up to one-third of patients. • It may alter treatment intent or radiotherapy-planning by detecting occult disease. • PET nodal status at diagnosis is an important predictor of relapse-free survival

    In carrying out bone scintigraphy in 224 cases over the 5 years from June, 1978 to May, 1983 as a part of the post-treatment management of cervical carcinoma. Bone metastases were seen in 12.5% (28 cases) of the subjects, about 6% of the total post-treatment cases of cervical carcinoma in the corresponding period (466 cases). Bone metastases were seen in 9.3% (16/172) of post-operative cases, compared with 23.1% (12/52) of non-operative cases. Bone metastases were not seen in clinical stages Ia through IIa (49 cases) but were seen in IIb or higher stages. Bone metastasis rates by histological type, according to WHO classification, were 12.8% (26/203) in squamous cell carcinoma, 5.9% (1/17) in adenocarcinoma, and 25% (1/4) in adenosquamous carcinoma. Among the squamous cell carcinoma cases, small cell non-keratinizing type had the highest bone metastasis rate (p<0.05). Of 172 post-operative cases, 20.8% (11/53) of those with lymphnode metastasis exhibited bone metastasis, higher than the 4.2% (5/119) in cases without lymphnode metastasis. As to CPL classification, bone metastasis was seen more often in L type (18.8%) than C(0.0%) or P types (6.6%). Our risk classification of 168 cases demonstrated that bone metastasis was not seen in risk I group (74 cases), but was seen in 6.7% (1/17) of risk II group and in 19.0% (15/79) of risk III group. Twenty-eight cases with bone metastasis included 11 cases with local recurrence, 8 with pulmonary metastases, 4 with hepatic metastases and 4 with Virchow's lymphnode metastases. The 28 bone metastasis cases included 10 cases with multiple bone metastases and 5 with only a single bone metastasis. Most bone metastases were seen in the lumbar vertebrae and the pelvic bone. Post-operative cases had more distant metastases than non-operative cases. On diagnosis of bone metastases and 17 of the 28 patients had pain, 6 of the remaining 11 patients developing pain thereafter. (J.P.N.)

    The treatment of uterine cervical carcinoma is largely dependent on the tumor stage. Despite significant inaccuracies in the clinical examination, uterine cervical cancer remains the only gynecological form of cancer still largely staged according to clinical findings. Although imaging is still not included in the staging the recently published revised FIGO (Federation International de Gynecologie et d'Obstetrique) system encourages the use of modern cross-sectional imaging (magnetic resonance imaging MRI and computed tomography CT). Due to its high soft tissue contrast MRI allows excellent non-invasive assessment of the cervix with direct tumor delineation as well as assessment of the prognosis based on morphological factors. Studies in the literature report an accuracy of 93% for MRI in the preoperative assessment of tumor size and in the differentiation of operable from advanced cervical cancer. Therefore MRI is considered to be the optimal modality for diagnostic evaluation starting from FIGO stage IB1, for radiation therapy planning, and for exclusion of recurrence in follow-up. In this paper we give an overview of the role of magnetic resonance imaging in preoperative staging of uterine cervical cancer. (orig.) [German] Die Therapieplanung beim Zervixkarzinom ist weitgehend von der Stadieneinteilung nach FIGO (Federation International de Gynecologie et d'Obstetrique) abhaengig, die trotz erheblicher Ungenauigkeiten bei der klinischen Stadieneinteilung weiterhin aufgrund klinischer Untersuchungsbefunde erfolgt. Obwohl bildgebende Verfahren nach wie vor fuer die Stadieneinteilung nicht vorgesehen sind, wird im kuerzlich erschienen revidierten Stagingsystem der FIGO zum ersten Mal die Verwendung moderner Schnittbilddiagnostik (MRT und CT) befuerwortet. Die MRT ermoeglicht dank ihres hohen Weichteilkontrasts ein ausgezeichnetes nichtinvasives Staging des Zervixkarzinoms mit direkter Tumordarstellung sowie einer Prognoseabschaetzung anhand

    In 117 patients with cervical carcinoma and 57 healthy women of the same age a radioimmunologic investigation of the systems hypophysis-adrenal glands and hypophysis-ovaries was carried out. Functional disorders in these systems were detected already before irradiation (hyperfunction of adrenal glands, diminished production of estradiol). The function of the systems hypophysis-adrenal glands and hypophysis-ovaries was diminished in patients with cervical carcinoma under radiotherapy. (author)

    Purpose: To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer. Methods and Materials: The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log–rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

    To evaluate the growth pattern depicted by MR imaging and used to differentiate between uterine cervical and endometrial carcinoma where the mass involves both the uterine corpus and cervix. The tumor growth pattern observed on MR images obtained between November 1989 and January in 1999 in 37 of 784 cervical carcinomas and 9 of 47 endometrial carcinomas in which the tumor involved both the uterine corpus and cervix was analysed. The histologic type was squamous (n=29), adenocarcinomatous (n=6) or adenosquamous (n=2) in cervical carcinoma, and carcinomatous (n=8) or adenosquamous (n=1) in endometrial carcinoma. A 1.5-T (Magnetom Vision, Siemens, Germany) and a 2.0-T unit (Spectro-20000, Goldstar, Korea) were used to obtain T1-and T2-weighted axial, T2-weighted sagittal and Gd-enhanced images. Tumor involvement of the uterine cervix was classified as Cp-n, Cp-x, or Cp-b according to involvement of the endocervix, exocervix or both. Tumors of the uterine corpus were classified as involving the mucosa(U-mu), myometrium(U-my) or serosa(U-se). In 37 cases of cervical carcinoma, all three involving the endocervix(Cp-n) invaded the endometrium(U-mu), three involving both the endo- and exocervix(Cp-b) invaded the endometrium(U-mu, 1 case), myometrium(U-my, 1 case), or serosa(U-se, 1 case), and 31 involving the full-thickness of the uterine cervix(Ct) invaded the endometrium (U-mu, 6 cases) or serosa(U-se, 25 cases). In nine cases of endometrial carcinoma, three involving the endometrium(U-mu) and five involving the myometrium(U-my) invaded the endocervix(Cp-n), and one involving the serosa(U-se) invaded the full-thickness of the uterine cervix(Ct). Cervical carcinoma tended to involve the entire cervix and the full thickness of the uterine corpus, but endometrial carcinoma tended to involve the endometrium or myometrium of the uterine corpus and endocervix

    To report the results of combined chemoradiation (CCRT) with cisplatin versus carboplatin in locally advanced cervical carcinoma. From 2009 to 2013, 255 patients with stage IIB-IVA cervical carcinoma, according to FIGO staging were prospectively assigned to be treated with pelvic radiotherapy followed by brachytherapy given concurrently with cisplatin or carboplatin in the treatment of locally advanced cervical cancer. Treatment outcomes and toxicitiy were evaluated. Two-hundred and thirteen patients could be evaluated. At a median follow-up time of 43 months (6–69 months), the 3-year local control, disease-free survival, metastasis-free survival and overall survival rates were 93, 80.8, 85.0 and 87.3 %, respectively. No statistical difference in terms of local control, disease-free survival, metastasis-free survival and overall survival rates between cisplatin and carboplatin treatments was observed in this study. Eighty-six percents of the patients in the carboplatin group could receive more than 4 cycles, while there were only 72 % in the cisplatin group who completed more than 4 cycles (p = 0. 02). In terms of acute toxicity, cisplatin caused significantly more anemia (p = 0.026), neutropenia (p = 0. 044) and nephrotoxicity (p = 0. 031) than carboplatin. No difference in late toxicity was observed in this study. Carboplatin yielded comparable results to cisplatin in concurrent chemo-radiation for locally advanced cervical cancer. In addition, carboplatin was associated with a better compliance rate and was associated with less of anemia, neutropenia and nephrotoxicity

    Forty MR imaging examinations in 38 patients with newly diagnosed or recurrent squamous cell carcinoma of the cervix were retrospectively evaluated and compared with clinical and surgical findings for staging. There was poor correlation between loss of fat planes and extension of tumor into the rectum or bladder, and it was impossible to differentiate bladder edema from direct invasion. MR imaging underestimated parametrial and pelvic sidewall extension when compared with physical exam under anesthesia. MR imaging was useful in the direct demonstration of a cervical mass and in detecting enlarged pelvic nodes

    Full Text Available Introduction : The aim of the present study was to evaluate the profile of VEGF-C gene expression in particular stages of cervical cancer (IB-IIIB and to estimate the correlation between VEGF-C mRNA quantity profile and clinical stage. Material and methods : Material for molecular analysis consisted of cervical cancer tissue specimens collected from 38 women (10, 15, 13 cases were classified as IB, IIB and IIIB, respectively. The control group was composed of normal cervical tissues collected from 10 women who underwent hysterectomy for non-oncological reasons. The number of VEGF-C mRNA copies in particular groups was estimated by the reverse transcription quantitative polymerase chain reaction (RT-qPCR method. Results: In the control group the average number of mRNA copies was 134 ± 36 (median: 106, in a group with stage IB it was 16 077 ± 7090 (median: 580, for stage IIB – 35 019 ± 8945 (median: 40 870. The highest number of mRNA VEGF-C copies was derived in a group of patients with cervical cancer of stage IIIB. The average quantity was 56 155 ± 12 470, whereas median 55 981. A statistically significantly higher level of VEGF-C gene expression was disclosed in cervical cancer specimens with stage IIB and IIIB than in the control group. In stage IIIB, the VEGF-C gene expression was significantly higher than in specimens derived from individuals in stage IB. Conclusions : In squamous cell carcinoma of the uterine cervix of stage IB-IIIB genes involved in lymphangio­genesis, especially VEGF-C , are expressed, which expression increases as the clinical stage of cervical cancer is higher.

    Objective: To investigate the proteomics differences between the high-sensitivity(HS) and the low-sensitivity(LS) groups of cervical carcinoma treated by concurrent chemoradiotherapy, and to confirm the sensitivity associated proteins in intermediate stage and advanced cervical carcinoma. Methods: Fresh carcinoma tissues were collected from 10 untreated cervical carcinoma patients. According to the response to concurrent chemoradiotherapy, the tissues were classified into HS group and LS group. In the first part of our experiment, protein separation was performed using two-dimensional gel electrophoresis (2-DE) with Amersham 18 cm linear pH 3-10 immobilized pH gradient(IPG) strips. The images of the gels were analyzed by PD-quest 7.0 software to find the differentially expressed protein-spots in each group. Then the differentially expressed protein-spots were incised from the gels and digested by trypsin. The peptide mass fingerprintings (PMF) was acquired by matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The proteins were identified by data searched in the Mascot-database. Two differentially expressed proteins were assayed by western blot and immunohistochemical methods. Results: Most of the gels were clear and successfully analyzed by PD-quest 7.0 software. Most of the protein-spots concentrated on the area of 20-100 KDa(Mw) and pH4-8. The average number of the protein-spots was 781 ± 74 in HS group and 766 ± 52 in LS group. The match rate was 87.6% between the two groups. Eight proteins highly in HS group but lowly expressed in LS group included hemoglobin subunit beta, caspase-14 precursor, calmodulindike, S100-A9 protein(MRP-14), galectin-7, HSKERC4, keratin 19 and actin. Ten proteins highly in LS group but lowly expression in HS group included anti HBs antibody light-chain Fab, lamin-B1, WARS protein, flavin reductase, glutamate dehydrogenase 1, nuclear matrix protein 238, retinal dehydrogenase 1, AF165172

    MINI: A 3D printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma. The personalized porous implant printed in Ti6AL4V provided excellent physicochemical properties and biological performance, including biocompatibility, osteogenic activity, and bone ingrowth effect. A unique case report. A three-dimensional (3D) printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma in a middle-age female patient. Papillary thyroid carcinoma is a malignant neoplasm with a relatively favorable prognosis. A metastatic lesion in multilevel cervical spine (C2-C4) destroys neurological functions and causes local instability. Radical excision of the metastasis and reconstruction of the cervical vertebrae sequence conforms with therapeutic principles, whereas the special-shaped multilevel upper-cervical spine requires personalized implants. 3D printing is an additive manufacturing technology that produces personalized products by accurately layering material under digital model control via a computer. Reporting of this recent technology for reconstructing multilevel cervical spine (C2-C4) is rare in the literature. Anterior-posterior surgery was performed in one stage. Radical resection of the metastatic lesion (C2-C4) and thyroid gland, along with insertion of a personalized implant manufactured by 3D printing technology, were performed to rebuild the cervical spine sequences. The porous implant was printed in Ti6AL4V with perfect physicochemical properties and biological performance, such as biocompatibility and osteogenic activity. Finally, lateral mass screw fixation was performed via a posterior approach. Patient neurological function gradually improved after the surgery. The patient received 11/17 on the Japanese Orthopedic Association scale and ambulated with a personalized skull-neck-thorax orthosis on

    AIM: This study evaluates the use of neck ultrasound in staging squamous oesophageal carcinoma. MATERIALS AND METHODS: A prospective analysis of the clinical, neck ultrasound (US) and thoraco-abdominal computed tomography (CT) findings in 121 patients with squamous oesophageal carcinoma at presentation was performed. The relationship between malignant neck nodes, mediastinal and abdominal adenopathy, location and size of the primary tumour was analysed. RESULTS: Ten of 121 patients (8%) had clinically palpable neck nodes which were deemed malignant in six (5%) following US and fine-needle aspiration for cytology. Of those 111 patients with no palpable neck nodes, 31 (28%) had malignant nodes shown on US. The more cephalad the location of the primary tumour, the higher the frequency of malignant neck nodes which were found in 80%, 52%, 29% and 9% of cervical, upper thoracic, mid-thoracic and lower thoracic oesophageal tumours, respectively. Eleven (29%) of the 38 patients with malignant neck nodes shown on US had no CT evidence of additional adenopathy in the mediastinum or upper abdomen. Neck US altered TNM staging in 22/121 (18%) patients at presentation. CONCLUSION: Neck US frequently detects clinically impalpable metastatic nodes leading to altered TNM staging in patients with squamous oesophageal carcinoma. We advocate its routine use when staging squamous oesophageal carcinoma. Griffith, J.F. 2000

    Background and purpose: High tumor interstitial fluid pressure (IFP) is associated with poor outcome in locally advanced carcinoma of the uterine cervix. We have recently developed a noninvasive assay of the IFP of tumors, and in this assay, the outward interstitial fluid flow velocity at the tumor surface (v 0 ) is measured by Gd-DTPA-based DCE-MRI and used as a parameter for IFP. Here, we investigated the independent prognostic significance of v 0 in cervical cancer patients given cisplatin-based concurrent chemoradiotherapy with curative intent. Patients: The study involved 62 evaluable patients from a cohort of 74 consecutive patients (Stage IB through IIIB) with a median follow-up of 5.5 years. Results: The actuarial disease-free survival (DFS) and overall survival (OS) at 5 years were 67% and 76%, respectively. Significant associations were found between v 0 dichotomized about the median value and DFS and OS, both in the total patient cohort and a subcohort of 40 Stage IIB patients. Multivariate analysis involving stage, tumor volume, lymph node status, and v 0 revealed that only v 0 provided independent prognostic information about DFS and OS. Conclusion: This investigation demonstrates a strong, independent prognostic impact of the pretreatment peritumoral fluid flow velocity in cervical cancer

    Purpose: To define the influence of the tumor size measured by computed tomography (CT) and lymph node involvement detected by CT in patients treated with radiation therapy for Stage IIB-IVA carcinoma of intact uterine cervix. Methods and Materials: This was a retrospective analysis of 233 patients with uterine cervical cancer managed with both external irradiation and high-dose-rate intracavitary brachytherapy (HDR-ICR) at Kanagawa Cancer Center. The results were analyzed for the end points of absolute survival (AS), disease-free survival (DFS), pelvic control (PC), and central control (CC). The parameters of stage, CT-measured anterior-posterior (AP) cervix size, and CT-detected lymph node metastases were evaluated using univariate and multivariate analysis. Results: The stage, AP cervix size, and lymph node involvement were significant pretreatment factors in univariate analysis with respect to AS, DFS, PC, and CC. Multivariate analysis confirmed that significant risk was associated with certain prognostic parameters. Those in terms of AS, in order of decreasing significance, were lymph node involvement, AP cervix size, age, and total HDR-ICR dose. When DFS was studied, lymph node involvement and AP cervix size were demonstrated to have a significant effect. Stage and lymph node involvement significantly affected PC. Conclusion: Because the International Federation of Gynecological Obstetrics staging system fails to incorporate important prognostic information about tumor volume and lymph node involvement, CT-detected lymph node metastases as well as CT-measured cervix size should be determined as complementary additional prognostic measures

    To evaluate usefulness of MR in assessment of tumor response to the chemotherapy, we prospectively studied cases of cervical carcinoma with more than 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were performed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherapy and MR amination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. The results were following. 1) All tumors dectrased in volume (m = 80.5%). 2) Five tumors (38.5%) reduced in stage, IB → CIS (1); IIA → CIS (1), IIA → IB (2), IIB → IB (1). 3) Depth of stromal invasion in MRI correlated well with that of histopathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessment of tumor response to chemotherapy

    Background: comprehensive literature on cervical cancer demonstrates, even today, the need for optimization of the timing of external-beam radiotherapy (EBRT) and high-dose-rate brachytherapy (HDR-BT) in the treatment of stage IIA/B-IIIB cervical carcinoma. Patients and methods: 210 patients with carcinoma of the cervix were treated in the Municipal Center of Oncoradiology between January 1991 and December 1996 (FIGO IIA: n = 10, FIGO IIB: n = 113, and FIGO IIIB: n = 87). Two regimens were compared: sequential radiation therapy (SRT) with 4 x 8 Gy HDR-BT to point A followed by EBRT, and continuous radiation therapy (CRT) in which 5 x 6 Gy HDR-BT to point A, one session per week, was integrated into the EBRT. A total dose of 68-70 Gy to point A and 52-54 Gy to point B was given in EBRT with SRT, five fractions per week were applied. Four fractions per week were applied in CRT, i.e., no EBRT was performed on the day of HDR-BT. Total doses to points A and B were identical in both regimens. Overall treatment time (OTT) amounted to 56 days for SRT and 35 days for CRT. Median follow-up time was 3.4 (2.5-4.2) years. Results: progression-free 5-year-survival (PFS) was 71% in the CRT and 56% in the SRT group. Nevertheless, this difference was not statistically significant (p = 1.00), and the same was found in a subgroup analysis of the different tumor stages, showing, however, an unequivocal trend. Late bladder and rectal injuries occurred in 13% and 25%, respectively. Late rectal injuries were significantly more frequent with SRT than CRT (35 patients in the SRT and 18 patients in the CRT group; p = 0.037). This was due to the higher doses per fraction of HDR-BT in the SRT group. No difference was found regarding late bladder injuries (p = 0.837). Conclusion: for the patients included in this study, no advantage has been found so far in using CRT, i.e., shortening the OTT by weekly integration of HDR-BT into EBRT. Nevertheless, an obvious trend exists. The dose of 8 Gy per

    MicroRNA (miRNA)-related single nucleotide polymorphisms (SNPs) may compromise miRNA binding affinity and modify mRNA expression levels of the target genes, thus leading to cancer susceptibility. However, few studies have investigated roles of miRNA-related SNPs in the etiology of cervical carcinoma. In this case–control study of 1,584 cervical cancer cases and 1,394 cancer-free female controls, we investigated associations between two miR-218-related SNPs involved in the LAMB3-miR-218 pathway and the risk of cervical carcinoma in Eastern Chinese women. We found that the pri-miR-218 rs11134527 variant GG genotype was significantly associated with a decreased risk of cervical carcinoma compared with AA/AG genotypes (adjusted OR=0.77, 95% CI=0.63-0.95, P=0.015). However, this association was not observed for the miR-218 binding site SNP (rs2566) on LAMB3. Using the multifactor dimensionality reduction analysis, we observed some evidence of interactions of these two SNPs with other risk factors, especially age at primiparity and menopausal status, in the risk of cervical carcinoma. The pri-miR-218 rs11134527 SNP was significantly associated with the risk of cervical carcinoma in Eastern Chinese women. Larger, independent studies are warranted to validate our findings

    The infiltration of the parametrium represents one of the most important factors that determine the prediction and treatment of cervical carcinoma. Our objetive is to evaluate the utility of magnetic resonance imaging (MRI) in the staging of cervical carcinomas, to establish the reliability of this technique and to carry out a comparative study of the sequences used to demonstrate the parametrial invasion. We have carried out a retrospective study on 44 patients diagnosed with cervix neoplasia, using clinical exploration and performing a biopsy. the MRI studies have been carried out using a 1 Tesla magnet and the sequences used have been SE T1, Se proton density (PD) and T2 and dynamic GRE after administering gadolinium intravenously in the axial and sagital projections. The stages determined by MRI have been compared to the anatomopathological stages of the surgical specimens in cases where surgery was carried out and with the clinical stage in cases where no radical surgery was carried out. A diagnosis value of MRI has been determined to demonstrate the parametrial invasion, comparing the SE T2 sequence with the dynamic GE sequence with gadolinium. We calculate the volume of the tumour in the MRI studies to evaluate the difference of the volume between patients with tumoral stages that are clinically surgical and not surgical. MRI determines the invasion of the parametrium with a sensitivity of 88.8%, a specificity of 80% a positive value of 76.1%, a negative predictive value of 90.9% and a reliability of 83.7%. For the SE T2 sequences the sensitivity was 86.6%, the specifity 80%, the posistive predictive value 81.25%, the negative predictive value 85.7% and the reliability 83.3%. For the dynamic GE sequence with intravenous gadolinium the sensitivity was 86.6%, the specifity 86.6%, the posistive predictive value 86.6%, the negative predictive value 86.6% and the reliability 86.6%. The use of the dynamic GE sequence after the intravenous administration of

    We created a new clinical staging system for end-stage gastrointestinal (GI) carcinoma to clarify the therapeutic goals for these patients. Data were obtained from a retrospective review of medical charts. Based on daily clinical observation of 144 patients with end-stage GI carcinoma, we classified the terminal stages as A, B, C, and D. The mean durations of terminal stages A, B, C, and D were 19, 16.6, 6.6, and 1.8 days, respectively, in patients with end-stage gastric cancer and 28.5, 9.1, 5.4, and 1.9 days, respectively, in patients with colorectal cancer. Moreover, 88.0% of patients with gastric carcinoma and 82.6% of patients with colorectal carcinoma passed through terminal stages A, B, C, and D sequentially. The patients in terminal stage B experienced temporary relief of symptoms, but those in terminal stage C did not (P terminal stages can easily be judged by clinical observation and may be an effective new tool with which to manage patients with end-stage GI carcinoma and their families.

    Age may affect the treatment choice and subsequent outcome in elderly patients with cervical cancer. Given the potential for cure with either surgery or chemoradiation in early stage disease, we aimed to determine whether a patient's age influenced treatment received and the ensuing outcome. We identified 303 patients with stages IB1-IIB cervical carcinoma treated at our institution between 2000 and 2010, who were divided into two groups based on age at time of diagnosis: stage at presentation, and grade. Women ≥ 65 years of age were less likely to receive primary surgical management (p=0.03). Age did not influence disease-specific or all-cause mortality. However, women over 65 years who underwent primary surgery were at significantly increased risk of all-cause mortality compared to younger women (HR 6.53, 95% CI: 2.57-16.6). Age appears to influence treatment received by patients with stages IB1-IIB cervical cancer. Although there was no difference in cancer-specific mortality stratified by type of treatment received, surgery was associated with a 6.5-fold increased risk of all-cause mortality among women 65 years or over. © 2013.

    The treatment for papillary thyroid carcinoma (PTC) without cervical lymph node metastasis (cN0) is controversial. This study was to explore a suitable method to dissect cervical lymph nodes for stage cN0 PTC patients. Eighty-four stage cN0 PTC patients, diagnosed by B ultrasound or cervical MRI from 2005--2006, were randomly divided into two groups. Thyroidectomy and ipsilateral central lymph node dissection were performed in Group A, while only thyroidectomy was performed in Group B. Each group contained 42 patients. Both groups took thyroxin tablets after operation. An average of 3 lymph nodes were found in each case of Group A, and the lymph node metastasis rate was 47.62%. The occurrence rates of complications were not significantly different between the two groups (P<0.05). Thyroidectomy plus ipsilateral central lymph node dissection is recommended for the treatment of stage cN0 PTC. It can also avoid damage of recurrent laryngeal nerve in re-dissection.

    Cervical cancer is the second most frequently occurring type of cancer in women worldwide. A persistent infection with high-risk human papillomavirus (HPV) is a necessary causal factor in cervical carcinogenesis. The distribution of HPV types in populations has been studied worldwide. In Indonesia, however, few data are available describing the prevalence of HPV. Cervical carcinoma is the most common female cancer in Indonesia and causes high morbidity and mortality figures. With HPV vaccination studies in progress, it is important to map the HPV status of a population that would benefit greatly from future prevention programs. We tested 74 cervical cancer specimens from consecutive, newly diagnosed cervical cancer patients in the outpatient clinic of the Dr. Cipto Mangunkusumo Hospital, Jakarta. After additional staining, the formalin-fixed, paraffin-embedded tissue samples were histologically classified. HPV presence and genotype distribution were determined by SPF10 polymerase chain reaction and line probe assay. HPV DNA of 12 different HPV types was detected in 96% of the specimens. The three most common types were 16 (44%), 18 (39%) and 52 (14%). In 14% of the specimens, multiple HPV types were present. The multiple HPV types were significantly more prevalent among adenosquamous carcinomas in comparison with squamous cell carcinoma or adenocarcinoma (P = 0.014). Distribution of HPV types in Indonesia with a more prominent role for HPV 18 is slightly different from that in other parts of the world. The high amount of multiple HPV infections found in adenosquamous carcinomas may prompt further research on the pathogenesis of this type of cervical tumours.

    Integration of human papillomavirus (HPV) DNA into the host genome can be a driver mutation in cervical carcinoma. Identification of HPV integration at base resolution has been a longstanding technical challenge, largely due to sensitivity masking by HPV in episomes or concatenated forms. The aim was to enhance the understanding of the precise localization of HPV integration sites using an innovative strategy. Using HPV capture technology combined with next generation sequencing, HPV prevalence and the exact integration sites of the HPV DNA in 47 primary cervical cancer samples and 2 cell lines were investigated. A total of 117 unique HPV integration sites were identified, including HPV16 (n = 101), HPV18 (n = 7), and HPV58 (n = 9). We observed that the HPV16 integration sites were broadly located across the whole viral genome. In addition, either single or multiple integration events could occur frequently for HPV16, ranging from 1 to 19 per sample. The viral integration sites were distributed across almost all the chromosomes, except chromosome 22. All the cervical cancer cases harboring more than four HPV16 integration sites showed clinical diagnosis of stage III carcinoma. A significant enrichment of overlapping nucleotides shared between the human genome and HPV genome at integration breakpoints was observed, indicating that it may play an important role in the HPV integration process. The results expand on knowledge from previous findings on HPV16 and HPV18 integration sites and allow a better understanding of the molecular basis of the pathogenesis of cervical carcinoma.

    Full Text Available Aims: (1 To map the extent of disease in women with stage I and II carcinoma cervix by multislice spiral computed tomography (CT, magnetic resonance imaging (MRI and sentinel nodes. (2 To assess accuracy of each modality individually and in conjunction with FIGO clinical staging. Design and Setting: Prospective, single-blind study. Departments of Obstetrics and Gynaecology, Radiodiagnosis, and Pathology, UCMS and GTBH and Division of Radiological Imaging and Bioinformatics, INMAS, Delhi. Material and Method: The study was conducted on 25 women with cervical cancer FIGO stage I and II. Each woman underwent clinical staging, multislice spiral CT and MRI which was compared to the gold-standard histopathology/cytology. The overall accuracy of each modality and improvement of clinical staging by CT/MRI were noted. Sentinel nodes were evaluated by intracervical Patent Blue V dye injection. Statistical Analysis: Sensitivity, specificity, positive and negative predictive values were calculated by 2Χ2 contingency tables. Results: The accuracy of staging by FIGO, CT and MRI was 68%, 52% and 80%, respectively. MRI and CT improved the overall accuracy of FIGO staging to 96% and 80%, respectively. Sentinel nodes were identified in 89% of patients with 91% accuracy. Conclusion: MRI emerges as the most valuable stand-alone modality improving accuracy of FIGO staging to 96%. Sentinel lymph-node evaluation appears promising in evaluating spread beyond cervix.

    Objective: To validate a combined technique in the detection of sentinel nodes in early cervix and vulvar cancer patients. Material and Methods: Seventy patients, 24 to 63 years old (average 40 years), with cervical cancer stages IA2, IB1 and IIA, and fourteen patients, 28 to 80 years old (median 68 years) with vulval neoplasm, stage I and II, had sentinel node (SN) detection using lymphoscintigraphy and a gamma probe in the surgical room, after injection of Tc 99m dextran and patent blue dye. Sentinel nodes were seen between 20 and 135 minutes after injection, in cervical cancer, and between one and sixty minutes in vulvar neoplasms. In patients with cervical tumors, 99 sentinel nodes were localized in the obturator region, 28 were interiliac, nine were located in the external iliac region, three in the common iliac region and one was found in perineum. In patients with a vulvar neoplasm, all sentinel nodes were located in the superficial inguinal region. The detection rate was 98,8% for cervical cancer and 100% for vulvar neoplasms, with bilateral drainage in 46% and 29% respectively. Metastases were found in 10,4% (7/65) of IB1 stage cervical cancer patients (6 squamous cell carcinomas - non keratinizing: 5, keratinizing: 1 and one adenocarcionoma) and none in four patients with IA2 stage (with non keratinizing squamous cell carcinoma). The patients with IIA stage cervical cancer (keratinizing squamous cell carcinoma) had metastases in the SN. Three out of 14 patients with vulvar cancer showed metastases in the sentinel node. Two of them had epidermoid carcinoma and one, malignant melanoma. There were no metastases in non-sentinel nodes when sentinel nodes were negative for metastases, both in cervical or vulvar cancer. Conclusion: It is feasible to localize sentinel nodes in cervical and vulvar cancer, using a combined technique with Tc 99m Dextran and 'patent blue'. (author)

    Uterine serous carcinoma (USC) is an aggressive type 2 endometrial cancer. Data on prognostic factors for patients with early-stage USC without adjuvant therapy are limited. This study aims to assess the baseline recurrence risk of early-stage USC patients without adjuvant treatment and to identify prognostic factors and patients who need adjuvant therapy. Sixty-eight patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II USC between 1997 and 2016 were included. All the cases did not undergo adjuvant treatment as institutional practice. Clinicopathological features, recurrence patterns, and survival outcomes were analyzed to determine prognostic factors. FIGO stages IA, IB, and II were observed in 42, 7, and 19 cases, respectively. Median follow-up time was 60 months. Five-year disease-free survival (DFS) and overall survival (OS) rates for all cases were 73.9% and 78.0%, respectively. On multivariate analysis, cervical stromal involvement and positive pelvic cytology were significant predictors of DFS and OS, and ≥1/2 myometrial invasion was also a significant predictor of OS. Of 68 patients, 38 patients had no cervical stromal invasion or positive pelvic cytology and showed 88.8% 5-year DFS and 93.6% 5-year OS. Cervical stromal invasion and positive pelvic cytology are prognostic factors for stage I-II USC. Patients with stage IA or IB USC showing negative pelvic cytology may have an extremely favorable prognosis and need not receive any adjuvant therapies. Copyright © 2018.

    The survival rates of 36 patients with early cervical carcinoma who had undergone total hysterectomy and bilateral salpingoophorectomy (THBSO) were compared to the survival rates of 41 patients who were subjected to the radical operation. As an integral part of their therapy both groups postoperatively received adequate doses of external beam supervoltage irradiation. Satisfactory results were obtained in both groups of patients. According to these results THBSO followed by postoperative radiotherapy is adequate treatment for early cervical carcinoma. In comparison to the radical operation or curietherapy alone this type of treatment has the advantage of requiring less surgical or radiotherapeutic expertise; it probably is associated with less morbidity

    To investigate the value of diffusion-weighted imaging (DWI) in evaluating parametrial invasion (PMI) in stage IA2-IIA cervical cancer. A total of 117 patients with stage IA2-IIA cervical cancer who underwent preoperative MRI and radical hysterectomy were included in this study. Preoperative clinical variables and MRI variables were analysed and compared between the groups with and without pathologically proven PMI. All variables except age were significantly different between patients with and without pathologic PMI (P < 0.05). All variables except squamous cell carcinoma (SCC) antigen were also significantly correlated with pathologic PMI on univariate analysis (P < 0.05). Multivariate analysis indicated that PMI on MRI (P < 0.001) and tumour apparent diffusion coefficient (ADC) (P = 0.029) were independent predictors of pathologic PMI. Area under the curve of PMI on MRI increased significantly from 0.793 to 0.872 when combined with tumour ADC (P = 0.002). When PMI on MRI was further stratified by tumour ADC, the false negative rate was 2.0 % (1/49). In stage IA2-IIA cervical cancer, tumour ADC and PMI on MRI seem to be independent predictors of pathologic PMI. Combining the two predictors improved the diagnostic performance of identifying patients at low risk of pathologic PMI. (orig.)

    Full Text Available Abstract Background Merkel cell polyomavirus (MCPyV was identified originally in Merkel cell carcinoma (MCC, a rare form of human skin neuroendocrine carcinoma. Evidence of MCPyV existence in other forms of malignancy such as cutaneous squamous cell carcinomas (SCCs is growing. Cervical cancers became the focus of our interest in searching for potentially MCPyV-related tumors because: (i the major histological type of cervical cancer is the SCC; (ii the uterine cervix is a common site of neuroendocrine carcinomas histologically similar to MCCs; and (iii MCPyV might be transmitted during sexual interaction as demonstrated for human papillomavirus (HPV. In this study, we aimed to clarify the possible presence of MCPyV in cervical SCCs from Japanese patients. Cervical adenocarcinomas (ACs were also studied. Results Formalin-fixed paraffin-embedded tissue samples from 48 cervical SCCs and 16 cervical ACs were examined for the presence of the MCPyV genome by polymerase chain reaction (PCR and sequencing analyses. PCR analysis revealed that 9/48 cervical SCCs (19% and 4/16 cervical ACs (25% were positive for MCPyV DNA. MCPyV-specific PCR products were sequenced to compare them with reference sequences. The nucleotide sequences in the MCPyV large T (LT-sequenced region were the same among MCPyV-positive cervical SCCs and AC. Conversely, in the MCPyV viral protein 1 (VP1-sequenced region, two cervical SCCs and three cervical ACs showed several nucleotide substitutions, of which three caused amino acid substitutions. These sequencing results suggested that three MCPyV variants of the VP1 were identified in our cases. Immunohistochemistry showed that the LT antigen was expressed in tumor cells in MCPyV-positive samples. Genotyping of human HPV in the MCPyV-positive samples revealed that infected HPVs were HPV types 16, 31 and 58 for SCCs and HPV types 16 and 18 for ACs. Conclusions This study provides the first observation that MCPyV coexists in a subset

    Cervical carcinoma is the second most common cancer and is an important cause of death in women worldwide. CCAAT/enhancer binding proteins (C/EBPs) are a family of transcription factors that regulate cellular differentiation and proliferation in a variety of tissues. However, the role of C/EBPα gene in cervical cancer is still not clear. We investigated the expression of C/EBPα gene in cervical squamous cell carcinoma. C/EBPα mRNA level was measured by real-time quantitative RT-PCR in cervical cancer tissues and their adjacent normal tissues. C/EBPα protein level was measured by immunohistochemistry. Methylation in the promoter of C/EBPα gene was detected by MALDI TOF MassARRAY. We transfected HeLa cells with C/EBPα expression vector. C/EBPα expression in HeLa cells was examined and HeLa cell proliferation was measured by MTT assay and HeLa cells migration was analyzed by matrigel-coated transwell migration assays. There were significant difference in C/EBPα protein expression between chronic cervicitis and cervical carcinoma (P < 0.001). CEBPα mRNA level was significantly lower in cervical cancer tissues than in normal cervical tissues (P < 0.01). Methylation of the promoter of CEBPα gene in CpG 5, CpG-14.15, CpG-19.20 were significantly higher in cervical cancer than in normal cervical tissues (P < 0.05, P < 0.01, P < 0.05, respectively). CEBPα pcDNA3.1 construct transfected into HeLa cells inhibited cell proliferation and decreased cell migration. Our results indicate that reduced C/EBPα gene expression may play a role in the development of cervical squamous cell carcinoma

    Purpose: To prove the superiority of concurrent radiochemotherapy (RTCT) over radiotherapy (RT) alone in locally advanced cervical carcinoma. Patients and Methods: In this randomized monocentric phase III study, 566 patients with squamous cell carcinoma of the cervix were included: 284 in arm A (RT) and 282 in arm B (concurrent RTCT with cisplatin 20 mg/m{sup 2} x 5 days). 238 patients (42%) were in stage IIB, 209 (37%) in stage IIIA, and 119 (21%) in stage IIIB. The median follow-up was 62.8 months. RT to the pelvis was delivered to a dose of 46 Gy/23 fractions. A cervical boost was given using the X-ray arch technique or high-dose-rate intracavitary brachytherapy at a dose of 10 Gy. Thereafter, patients were evaluated: those with good response optionally underwent surgery and the others continued RT until 64 Gy/pelvis (with or without CT according to randomization) and 14 Gy/central tumor volume. Results: The 5-year survival rate was statistically significantly superior in the concurrent RTCT group (74%) versus the RT group (64%; p < 0.05). In patients undergoing surgery after RT or RTCT, superior results were obtained, compared to the nonoperated patients: 5-year survival rate 86% versus 53% (p < 0.01). 192 failures were recorded: 109 (38%) after RT alone versus 83 (29%) after concurrent RTCT (p < 0.01). Conclusion: The results of this study prove the obvious superiority of concurrent RTCT with 5-day cisplatin compared to RT alone in patients with locally advanced cervical carcinoma, regarding local control (78% vs. 67%) and 5-year survival rates (74% vs. 64%).

    The purpose of this study was to evaluate the efficacy and toxicity of docetaxel as single-agent neoadjuvant chemotherapy in locoregionally advanced cervical carcinoma. Between April 1998 and August 2000, 38 untreated patients with International Federation of Gynecology and Obstetrics stages IIB to IVA were entered onto this study. The median age was 44 years (range: 25-66 years). Stages: IIB 22 patients, IIIB 15 patients, and IVA 1 pt. Treatment consisted of docetaxel 100 mg/m2 IV infusion during 1 hour. Standard premedication with dexamethasone, diphenhydramine, and ranitidine was used. Cycles were repeated every 3 weeks for three courses, followed by radical surgery when it was judged appropriate, or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. 106 cycles of therapy were administered; all patients were evaluable for TX, whereas 35 were evaluable for response (3 patients refused further treatment after the first cycle of therapy). Complete response (CR): 1 patient (3%); partial response: 11 patients (31%), for an overall objective response rate of 34% (95% CI: 15-53%); no change (NC): 16 patients (46%); and progressive disease: 7 patients (20%). Six patients (17%) underwent surgery and a pathologic CR was confirmed in 1 of them. The median time to treatment failure and the median survival have not been reached yet. The limiting toxicity was leukopenia in 25 patients (69%) (G1-G2: 14 patients, G3: 10 patients, and G4: 1 patient). Neutropenia: 28 patients (78%) (G1-G2: 10 patients, G3: 8 and G4: 10). Myalgias: 17 patients (47%) (G1-G2: 15 patients and G3: 2 patients). Emesis: 21 patients (55%) (G1-G2: 19 patients and G3: 2 patients). Alopecia G3: 13 patients (36%); rash cutaneous 26 patients (68%) (G1-G2: 22 patients and G3: 4 patients). There were no hypersensitivity reactions or fluid-retention syndrome. The received dose intensity was 91% of that projected. Docetaxel is an active drug against advanced

    We sought to review outcomes in patients with stage IVB carcinoma of the cervix treated with irradiation in combination with chemotherapy. We report outcomes of 24 consecutive patients with good performance status treated from 1998 to 2005. Most of these patients underwent concurrent irradiation with platinum-based chemotherapy. Some patients received subsequent systemic chemotherapy. All patients underwent external beam radiotherapy; 7 patients (29%) had additional high-dose-rate and 12 (50%) low-dose-rate brachytherapy. Two patients (8%) received an intensity modulated radiation therapy (IMRT) boost instead of brachytherapy. The mean dose to point A was variable (73.9±19.2 Gy). Twenty patients (83%) received radio-sensitizing platinum-based chemotherapy, and the remaining had radiotherapy alone. Seven patients (29%) had further combination chemotherapy. Therapy was well tolerated. The overall survival was 44% at 36 months and 22% at 5 years. Patients with stage IVB cervical cancer have mostly been treated with palliative intent. With the advent of concurrent chemoradiation, we have treated many of these cases with aggressive combination therapy. In this series, the use of radiotherapy and multiagent chemotherapy in patients with stage IVB cervical carcinoma and good performance status was well tolerated and resulted in higher survival rates than previously reported.

    Radiological demonstration of lymph vessels and lymph nodes may be achieved only by direct lymphography, which is performed by injecting contrast material directly into the lymph vessels, lymph nodes, or occasionally into lymph cysts. Clinical lymphography is performed essentially according to the direct technique of Kinmonth (1952 and 1954). Lymphography has become a routine procedure in patients with carcinoma of the uterine cervix. Thorough assessment of the extent of carcinoma of the uterine cervix is necessary to the intelligent management of any patient with uterine carcinoma. This presentation is to outline the technique of lymphangio-adenography (lymphography), lymphographic finding and diagnostic criteria of the cervical carcinoma, and evaluation of the accuracy of lymphographic diagnosis in cervical carcinoma. A retrospective review of the lymphograms of 145 patients with carcinoma of the uterine cervix was undertaken. All lymphograms were performed at Kang Nam St. Mary's and St. Mary's Hospitals, Catholic Medical College from 1975 to 1982. Of these patients 87 were got radical hysterectomy and lymphographic diagnosis was compared with tissue pathology of the lymph nodes removed, and determined the diagnostic accuracy of lymphography. Lymphography can make a significant contribution in the pretreatment assessment of patients with carcinoma of the uterine cervix. Strick adherence to rigid criteria will yield excellent pathologic correlation in the event of a positive radiographic diagnosis of metastatic carcinoma. Once a positive diagnosis is made, it should influence the management of the cancer patients. The results were as follow: 1. The accuracy of lymphography in diagnosing lymph node matastasis of carcinoma of the uterine cervix was 85.1%, 82.4% in sensitivity and 86.8% in specificity. 2. Metastic lymph nodes were moderately to markedly enlarged and irregular in shape and shown motheaten marginal filling defects in 92.7%. These were ranged from 3mm

    To evaluate the efficacy and toxicity of vinorelbine (VNB) as single-agent neoadjuvant chemotherapy in advanced cervical carcinoma (ACC). Between December 1993 and October 1995, 43 untreated patients with stages IIB to IVA squamous cell cervical cancer were entered onto this study. Forty-two patients are assessable for response and 43 for toxicity. The median age was 46 years (range, 28 to 65). Distribution by stages (International Federation of Gynecology and Obstetrics [FIGO]) was as follows: IIB, 18 patients; IIIA, one; IIIB, 19; and IVA, five. Therapy consisted of VNB 30 mg/m2 by 20-minute intravenous (IV) infusion repeated weekly for 12 injections and followed by radical surgery if feasible or definitive radiotherapy. Both staging and response assessment were performed by a multidisciplinary team. One patient was considered not assessable for response. A total of 493 cycles of therapy were administered and objective remissions were observed in 19 of 42 patients (45%; 95% confidence interval, 30% to 60%). Two patients (5%) had a complete response (CR) and 17 (40%) a partial response (PR); no change (NC) was observed in 16 (38%) and progressive disease (PD) in seven (17%). Six of 19 patients (32%) who achieved objective responses (ORs) underwent surgery. The median time to failure and median survival time have not been reached yet. There were no therapy-related deaths. The dose-limiting toxicity was myelosuppression. Leukopenia occurred in 35 patients (81%) and was grade 3 or 4 in seven (17%). Twelve patients (28%) developed peripheral neuropathy, while myalgias occurred in 10 (23%). Constipation was observed in nine patients (21%), one with a prolonged ileum. Phlebitis was recorded in 18 patients (41%). In contrast, emesis and mucositis were rarely observed. No patient developed alopecia grade 3. By the end of the twelfth course of treatment, the average received dose-intensity was 85.4% of that projected. VNB is an active drug against ACC with moderate

    To assess the diagnostic accuracy of magnetic resonance imaging in local staging of endometrial carcinoma, and to review the results and pitfalls described in the literature. Thirty women with a histological diagnosis of endometrial carcinoma underwent magnetic resonance imaging. Unenhanced T2-weighted and dynamic contrast-enhanced Ti-weighted sequences were obtained. Hysterectomy and salpingo-oophorectomy was performed in all patients. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for the detection of deep myometrial and cervical infiltration. For deep myometrial infiltration T2-weighted sequences reached a sensitivity of 85%, specificity of 76%, PPV of 73%, NVP of 87%, and accuracy of 80%, while contrast-enhanced scans reached a sensitivity of 90%, specificity of 80%, PPV of 82%, NPV of 89%, and accuracy of 85%. For cervical infiltration T2-weighted sequences reached a sensitivity of 75%, specificity of 88%, PPV of 50%, NPV of 96%, and accuracy of 87%, while contrast-enhanced scans reached a sensitivity of 100%, specificity of 94%, PPV of 75%, NPV of 100%, and accuracy of 95%. Unenhanced and dynamic gadolinium-enhanced magnetic resonance allows accurate assessment of myometrial and cervical infiltration. Information provided by magnetic resonance imaging can define prognosis and management.

    Purpose: Blood perfusion in tumors is spatially and temporally heterogeneous, resulting in local fluctuations in tissue oxygen tension (pO 2 ) and tissue regions showing cycling hypoxia. In this study, we investigated whether the pO 2 fluctuation pattern and the extent of cycling hypoxia differ between tumor types showing high (e.g., cervical carcinoma xenograft) and low (e.g., melanoma xenograft) fractions of connective tissue-associated blood vessels. Methods and Materials: Two cervical carcinoma lines (CK-160 and TS-415) and two melanoma lines (A-07 and R-18) transplanted into BALB/c nu/nu mice were included in the study. Tissue pO 2 was measured simultaneously in two positions in each tumor by using a two-channel OxyLite fiber-optic oxygen-sensing device. The extent of acute and chronic hypoxia was assessed by combining a radiobiological and a pimonidazole-based immunohistochemical assay of tumor hypoxia. Results: The proportion of tumor regions showing pO 2 fluctuations, the pO 2 fluctuation frequency in these regions, and the relative amplitude of the pO 2 fluctuations were significantly higher in the melanoma xenografts than in the cervical carcinoma xenografts. Cervical carcinoma and melanoma xenografts did not differ significantly in the fraction of acutely hypoxic cells or the fraction of chronically hypoxic cells. However, the ratio between fraction of acutely hypoxic cells and fraction of chronically hypoxic cells was significantly higher in melanoma than in cervical carcinoma xenografts. Conclusions: Temporal heterogeneity in blood flow and tissue pO 2 in tumors may depend on tumor histology. Connective tissue surrounding microvessels may stabilize blood flow and pO 2 and, thus, protect tumor tissue from cycling hypoxia.

    Twenty patients with Stage IIB carcinoma of the cervix who did not undergo pretherapy para-aortic lymphadenectomy, but who had negative preradiation therapy lymphangiograms, were treated with pelvic radiation plus hydroxyurea. Patients received a median of 5020 rads of pelvic radiation plus 4000 rads of radium to point A. During radiation therapy and for a total of 12 weeks, patients received hydroxyurea administered at a dose of 80 mg/kg of body weight every 3 days if the white blood cell count was greater than or equal to 2,500/mm3 and platelets were greater than or equal to 75,000/mm3. The median follow-up time was 28 months (6 to 83 months). The estimated 5-year survival rate was 92%. Seventeen patients are alive with no evidence of disease (median, 28 months); one died of intercurrent disease with no evidence of disease (17 months); one is alive with no evidence of disease after recurrence (18 months); and one died of cervical cancer (22 months). The survival rate of patients with nonsurgically staged negative pretherapy lymphangiograms who had Stage IIB cervical cancer treated by pelvic radiation therapy plus hydroxyurea approximated the improved survival rate reported for patients with negative pretherapy para-aortic lymphadenectomy who were treated with pelvic radiation therapy plus hydroxyurea. Both studies would suggest that pelvic radiation plus hydroxyurea improves the rate of survival in patients with Stage IIB cervical cancer

    To study the process of cell death in cervical squamous cell carcinoma (SCC) after radiation, an ultrastructural and immunohistochemical study was performed. Paraffin-embedded tissue blocks of biopsy samples pre- and post-radiation stage III SCC (n=15) were collected. Irradiation caused varying ultrastructural changes including nuclear and cytoplasmic disorganization suggesting cell necrosis. Immunohistochemically, the pre-radiation specimens showed no positive reaction for tumor necrosis factor-alpha (TNF-α), tumor necrosis factor-receptor (TNF-γ) or Fas. C-fos, p53 and bcl-2 showed positive reactions in only a few non-irradiated specimens. All of the irradiated specimens showed a positive reaction for TNF-α, and variable positive reactions were observed for TNF-γ, Fas, p53, c-fos and bcl-2. These results suggest that TNF-α, TNF-γ, and c-fos are responsible for radiation induced cell death in cervical SCC. (author)

    Carcinoembryonic antigen (CEA) has been studied in the field of gynecologic malignancy to determine whether it can be used as a tumor marker for early detection of recurrence or evaluation of therapeutic results. From January 1985 through December 1989, a total of 239 cervical cancer patients were entered for an analysis of plasma CEA level in the group with cervical cancer compared to the control group consisting of 65 normal healthy women and 18 women with benign gynecologic disease. Plasma CEA levels appear to be directly related with the tumor extension and as stages advance, the incidence of patients with abnormal plasma CEA levels is increased. Also, there seems to be a little higher incidence of abnormal CEA levels in patients with adenocarcinomas or adenosquamous carcinoma but not statistically significant because of small number of patients. When the patients developed recurrence, plasma CEA levels are markedly elevated in the majority, particularly in patients with hepatic metastases. In conclusion, serial plasma CEA checks could be used to detect recurrence during follow-up after treatment of cervical cancer.

    Pregnancy and cervical carcinoma occurring concomitantly causes therapeutic and ethical dilemmas. The management for this situation will depend on the gestational age at the time of diagnosis, disease staging, size of the lesion and the patient’s wish to maintain pregnancy and fertility. Review of the literature suggest that pregnancy does not seem to influence the prognosis of cervical cancer. (author)

    Cervical carcinoma is one of the leading causes of cancer-related death for female worldwide. Eukaryotic initiation factor 5A2 belongs to the eukaryotic initiation factor 5A family and is proposed to be a key factor involved in the development of diverse cancers. In the current study, a series of in vivo and in vitro investigations were performed to characterize the role of eukaryotic initiation factor 5A2 in oncogenesis and metastasis of cervical carcinoma. The expression status of eukaryotic initiation factor 5A2 in 15 cervical carcinoma patients was quantified. Then, the effect of eukaryotic initiation factor 5A2 knockdown on in vivo tumorigenicity ability, cell proliferation, cell cycle distribution, and cell mobility of HeLa cells was measured. To uncover the mechanism driving the function of eukaryotic initiation factor 5A2 in cervical carcinoma, expression of members within RhoA/ROCK pathway was detected, and the results were further verified with an RhoA overexpression modification. The level of eukaryotic initiation factor 5A2 in cervical carcinoma samples was significantly higher than that in paired paratumor tissues ( P cycle arrest ( P ROCK I, and ROCK II were downregulated. The above-mentioned changes in eukaryotic initiation factor 5A2 knockdown cells were alleviated by the overexpression of RhoA. The major findings outlined in the current study confirmed the potential of eukaryotic initiation factor 5A2 as a promising prognosis predictor and therapeutic target for cervical carcinoma treatment. Also, our data inferred that eukaryotic initiation factor 5A2 might function in carcinogenesis of cervical carcinoma through an RhoA/ROCK-dependent manner.

    Carcinomas of the mesopharynx, hypopharynx, and larynx with early-stage primary tumor and with cervical lymph node metastasis, were treated by neck dissection for cervical metastasis and definitive irradiation of the primary tumor. In this study, the primary sites of the 16 cases were the mesopharynx (10), the hypopharynx (3), and the larynx (3). Twelve cases of early T stages (T1 or T2) and 15 cases of advanced N stages (N2 or N3) were chosen for this treatment concept. Neck lesions were controlled in all cases and all the primary tumors showed complete response at the end of the initial treatment. One case of mesopharyngeal cancer died due to recurrence of the primary tumor and one case of hypopharyngeal cancer died due to complicated lung cancer. The treatment modality for cases of early primary cancer and advanced cervical lymph node metastasis requires well-balanced strategies for both lesions. In these cases, optimal prognosis was obtained because of careful patient selection. The treatment strategy described in this paper should be considered for cases of early T tumors and advanced N tumors. (author)

    Neoadjuvant chemotherapy followed by surgery is a promising approach in locally advanced cervical carcinoma. The aim of this study was to evaluate the feasibility, technical aspects, and clinical results of surgery after induction chemotherapy in this patient population. Forty-one untreated cervical carcinoma patients staged as IB2 to IIIB received three 21-day courses of cisplatin 100mg/m2 on day 1 and gemcitabine 1000 mg/m2 on days 1 and 8 followed by surgery or concomitant chemoradiation. The response to chemotherapy, operability, surgical/pathological findings, disease-free period, and survival of the surgically treated patients were evaluated. All 41 patients were evaluated for toxicity and 40 were evaluated for response. The overall objective response rate was 95% (95% confidence interval 88%-100%), and was complete in three patients (7.5%) and partial in 35 (87.5%). Granulocytopenia grades 3/4 occurred in 13.8% and 3.4% of the courses, respectively, whereas nonhematological toxicity was mild. Twenty-three patients underwent type III radical hysterectomy. Mean duration of surgery was 3.8 h (range 2:30-5:20), median estimated blood loss was 670 ml and median hospital stay was 5.2 days. Intraoperative complications occurred in one case (venous injury). In all but one case the resection margins were negative. Four patients (17%) had positive nodes (one node each); six (26%) had complete pathologic response, three (13%) had microscopic; and 14 (60%) macroscopic residual disease. At 24 months of maximum follow-up (median 20), the disease-free and overall survival rates were 59% and 91%, respectively. Induction chemotherapy with cisplatin/gemcitabine produced a high response rate and did not increase the difficulty of surgery. Operating time, blood loss, intraoperative complications, and hospital stay were all within the range observed for type III hysterectomy in early stage patients. We therefore conclude that type III radical hysterectomy is feasible in locally

    An appraisal of the dosimetry of a modified brachytherapy approach is presented for improving the local control of extensive vaginal involvement from carcinoma of the cervix. This approach incorporates radium needles implant to the vaginal disease in conjunction with the usual routine intracavitary radium application. The aim of the interstitial implant is specifically to supplement the dose to the vaginal disease from the intracavitary application. Our procedure for accomplishing this boost in the dose to the vagina depends on the location, extent and thickness of the vaginal lesion following external beam irradiation of the whole pelvis. An increase of greater than 50% in the dose to the vaginal disease is gained by this combination intracavitary/implant approach which has been used in a variety of cases covering virtually all pertinent stages of cervical carcinoma. Discussion of the dosimetry of example cases is presented to demonstrate the value of combining interstitial and intracavitary therapy for this specific clinical application. (orig.)

    Hydronephrosis is frequently encountered in advanced stage cervical cancers, and may be associated with mortality. In the present study, we aimed to demonstrate the effect of hydronephrosis on survival in patients with inoperable advanced stage cervical cancer. The study data were acquired by retrospective analysis of the patient records belonging to 165 women with FIGO (International Federation of Gynecology and Obstetrics) stage-IIIB or more advanced cervical cancer, which were not surgical candidates. Parameters including patient age, pathological diagnosis, disease stage, pelvic sidewall extension, presence of hydronephrosis and administration of chemoradiation were analyzed. Further, the effects of these variables on survival were assessed. P values less than 0.05 were considered statistically significant. The distribution of the study patients according to disease stage was as follows: 131 (79.4%) had stage-IIIB, 18 (10.9%) had stage-IVB and 16 (% 9.7) patients had stage-IVA disease. Hydronephrosis was not evident in 91 (55.2%) of these patients, whereas 41 (24.8%) had unilateral and 33 (20%) patients had bilateral hydronephrosis. When compared to mean survival in patients who did not have hydronephrosis, survival was significantly shortened in patients who had bilateral and unilateral hydronephrosis (phydronephrosis (p>0.05). Although patient age, pathological type, pelvic involvement, and chemotherapy treatment rates were similar (p>0.05), radiotherapy requirement rate and disease stage were significantly different among the study groups (pHydronephrosis was found to be a significant predictor of poor survival in patients with advanced stage cervical cancer, irrespective of unilateral or bilateral involvement.While waiting for future studies with larger sample sizes, we believe that the FIGO stages in advanced cervical cancer could further be stratified into subgroups according to presence or absence of hydronephrosis.

    The aim of this study was to survey gynecologic oncologists and fellows-in-training regarding the role of radical trachelectomy (RT) and conservative surgery in patients with early-stage cervical cancer. From June 2012 to September 2012, the Society of Gynecologic Oncology member practitioners (n = 1353) and gynecologic oncology fellows (n = 156) were sent group-specific surveys investigating current practice, training, and the future of RT for early-stage cervical cancer management. Twenty-two percent of practitioners (n = 303) and 24.4% of fellows (n = 38) completed the surveys. Of the practitioners, 50% (n = 148) report performing RT, 98% (n = 269) support RT as treatment for squamous carcinoma, and 71% (n = 195) confirm the use of RT for adenocarcinoma. Most practitioners offer RT treatment for stages IA2 to IB1 smaller than 2 cm (n = 209, 76.8%) regardless of grade (77.7%) or lymph vascular space invasion (n = 211, 79.3%). Only 8% (n = 23) of practitioners feel that RT is appropriate for stage IBI larger than 2 cm. Respectively, both practitioners and fellows most frequently perform robotic-assisted (47.0%, n = 101 and 59.1%, n = 13) and abdominal (40.5%, n = 87 and 68.2%, n = 15) RT approaches. After training, fellows project the use of robotic-assisted (71%, n = 22) or abdominal methods (58.1%, n = 18). Overall, 75% (n = 227) of practitioners and 60% (n = 23) of fellows speculate that over the next 5 years, less radical procedures will be used to manage early-stage cervical cancer. Our findings suggest that practitioners and fellows believe RT remains an option for early-stage cervical cancer patients. However, a significant proportion of all respondents believe that less radical surgery may be a future consideration for patients with low-risk early-stage cervical cancer.

    Cervical cancer is the second most common cancer among women in Sudan, with more than two-thirds of all women with invasive cervical cancer being diagnosed at an advanced stage (stages III and IV). The lack of a screening program for cervical cancer in Sudan may contribute to the late presentation...... of this cancer, but other factors potentially associated with advanced stages of cervical cancer at diagnosis are unknown. The purpose of this research was to investigate the relationship between age, marital status, ethnicity, health insurance coverage, residence in an urban vs a rural setting, and stage (at...... diagnosis) of cervical cancer in Sudan....

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

    Eighty-four biopsies derived from cervical tissues were analyzed for the presence of human papillomavirus (HPV) DNA types 6, 16 and 18 using Southern blot hybridization. HPV 6 was found in none of the cervical biopsies, and HPV types 16 and 18 were found in 44% of them. The rate of HPV 16/18 positive samples increased proportionally to the severity of the lesion. In normal tissue there were no positive samples, in mild and moderate dysplasia HPV 16/18 was present in 20% and in severe dysplasia and invasive carcinomas in 37 and 50%, respectively. In biopsies from 13 cases with squamous cell carcinoma of the uterine cervix and CIN III lesions HPV 16 was integrated within the host genome. It was concluded that the virus could be integrated at variable, presumably randomly selected chromosomal loci and with different number of copies. Transcription of HPV 16 and 18 was detected in one cervical cancer in HeLa cells, respectively. These results imply that HPV types 16 and 18 play an etiological role in the carcinogenesis of human cervical epithelial cells. (author)

    Squamous cell carcinoma (SCC) of the uterine cervix and oral cavity are most common cancers in India. Telomerase reverse transcriptase (TERT) overexpression is one of the hallmarks for cancer, and activation through promoter mutation C228T and C250T has been reported in variety of tumors and often shown to be associated with aggressive tumors. In the present study, we analyzed these two hot spot mutations in 181 primary tumors of the uterine cervix and oral cavity by direct DNA sequencing and correlated with patient's clinicopathological characteristics. We found relatively high frequency of TERT hot spot mutations in both cervical [21.4 % (30/140)] and oral [31.7 % (13/41)] squamous cell carcinomas. In cervical cancer, TERT promoter mutations were more prevalent (25 %) in human papilloma virus (HPV)-negative cases compared to HPV-positive cases (20.6 %), and both TERT promoter mutation and HPV infection were more commonly observed in advanced stage tumors (77 %). Similarly, the poor and moderately differentiated tumors of the uterine cervix had both the TERT hot spot mutations and HPV (16 and 18) at higher frequency (95.7 %). Interestingly, we observed eight homozygous mutations (six 228TT and two 250TT) only in cervical tumors, and all of them were found to be positive for high-risk HPV. To the best of our knowledge, this is the first study from India reporting high prevalence of TERT promoter mutations in primary tumors of the uterine cervix and oral cavity. Our results suggest that TERT reactivation through promoter mutation either alone or in association with the HPV oncogenes (E6 and E7) could play an important role in the carcinogenesis of cervical and oral cancers.

    This study aimed to investigate the value of diffusion-weighted imaging (DWI) in combination with conventional magnetic resonance imaging (MRI) for improving tumor detection in young patients treated with fertility-sparing surgery because of early cervical carcinoma. Fifty-four patients with stage Ia or Ib1 cervical carcinoma were enrolled into this study. Magnetic resonance examinations were performed for these patients using conventional MRI (including T1-weighted imaging, T2-weighted imaging, and dynamic contrast-enhanced MRI) and DWI. The apparent diffusion coefficient (ADC) values of cervical carcinoma were analyzed quantitatively and compared with that of adjacent epithelium. Sensitivity, positive predictive value, and accuracy of 2 sets of MRI sequences were calculated on the basis of histologic results, and the diagnostic ability of conventional MRI/DWI combinations was compared with that of conventional MRI. The mean ADC value from cervical carcinoma (mean, 786 × 10 mm/s ± 100) was significantly lower than that from adjacent epithelium (mean, 1352 × 10 mm/s ± 147) (P = 0.01). When the threshold ADC value set as 1010 × 10 mm/s, the sensitivity and specificity for differentiating cervical carcinoma from nontumor epithelium were 78.2% and 67.2%, respectively. The sensitivity and accuracy of conventional MRI for tumor detection were 76.0% and 70.4%, whereas the sensitivity and accuracy of conventional MRI/DWI combinations were 91.7% and 90.7%, respectively. Conventional MRI/DWI combinations revealed a positive predictive value of 97.8% and only 4 false-negative findings. The addition of DWI to conventional MRI considerably improves the sensitivity and accuracy of tumor detection in young patients treated with fertility-sparing surgery, which supports the inclusion quantitative analysis of ADC value in routine MRI protocol before fertility-sparing surgery.

    Objective: To evaluate the value of lymphoscintigraphy for cervical sentinel lymph node (SLN) detection in patients with oral squamous cell carcinoma. Methods: Twenty-one patients with clinically N 0 oral squamous carcinoma underwent preoperative lymphoscintigraphy and intraoperative methylene blue location. The results were compared with pathological findings. Results: 1) The sensitivity of lymphoscintigraphy for detecting SLN was 100%(21/21), and methylene blue was 85% (17/20). 2)Both SLN biopsy and cervical ablative dissection confirmed that 33.3% (7/21) patients were with cervical lymph node metastasis. Fourteen non-metastatic SLNs comfirmed by biopsy were also proved with the findings of neck dissection, and the specificity was 100%. Conclusion: Lymphoscintigraphy can detect the cervical SLN and accurately predict cervical lymph node metastasis in patients with oral squamous cell carcinoma.(authors)

    This study was aimed to investigate the reliability of a computer application for assessment of the stages of cervical vertebra maturation in order to determine the stage of skeletal maturity. For this study, digital lateral cephalograms of 99 subjects (52 females and 47 males) were examined. The following selection criteria were used during the sample composition: age between 9 and 16 years, absence of anomalies of the vertebrae, good general health, no history of trauma at the cervical region. Subjects with lateral cephalograms of low quality were excluded from the study. For the purpose of this study a computer application Cephalometar HF V1 was developed. This application was used to mark the contours of the second, third and fourth cervical vertebrae on the digital lateral cephalograms, which enabled a computer to determine the stage of cervical vertebral maturation. The assessment of the stages of cervical vertebral maturation was carried out by an experienced orthodontist. The assessment was conducted according to the principles of the method proposed by authors Hassel and Farman. The degree of the agreement between the computer application and the researcher was analyzed using by statistical Cohen Kappa test. The results of this study showed the agreement between the computer assessment and the researcher assessment of the cervical vertebral maturation stages, where the value of the Cohen Kappa coefficient was 0.985. The computer application Cephalometar HF V1 proved to be a reliable method for assessing the stages of cervical vertebral maturation. This program could help the orthodontists to identify the stage of cervical vertebral maturation when planning the orthodontic treatment for the patients with skeletal disharmonies.

    Full Text Available INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16 by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC, six cases were Keratinized Squamous Cell Carcinoma (KSCC and four cases were Adenocarcinoma (ADC. Immunohistochemistry study showed positivity in eleven cases (55%; seven cases (35% were non-keratinized squamous cell carcinoma; three cases (15% were keratinized squamous cell carcinoma and one case (5% belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC. The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinomas

    Extensive debulking is accepted as the primary method of operative management for carcinoma of the ovary. However, there is no consensus regarding the role of appendectomy in primary surgical treatment. The aim of this study was to assess the role of appendectomy in the surgical staging and cytoreduction of ovarian carcinoma. The study was a retrospective review of 90 primary malignant ovarian carcinoma patients who had an appendectomy in addition to primary cytoreductive surgery. Out of 90 patients, 10 (11.1%) had metastasis to the appendix. The rate of metastasis to the appendix was 11.5% (9/78) in malignant epithelial ovarian carcinomas and 8.3% (1/12) in non-epithelial ovarian tumors. Of the patients with metastasis in the appendix, malignant epithelial ovarian tumors were identified in 90% (serous: 70%; clear cell: 20%), and non-epithelial malignant ovarian tumor were disclosed in 10% (granulosa cell carcinoma). There were no metastases to the appendix in the other histological types. Although metastasis to the appendix was not observed in early stage ovarian carcinomas, it was detected in 21.4% (9/42) of stage III and 50% (1/2) of stage IV. Macroscopic tumor metastasis in the abdomen was noted in all patients with metastasis to the appendix. Appendectomy for stage I and II patients was not beneficial and did not affect final staging. As a result, for the proper staging of ovarian carcinoma there is no advantage to the addition of routine appendectomy to primary cytoreductive surgery in early stage (stage I and II) malignant epithelial ovarian tumors. Appendectomy would contribute to the cytoreduction of advanced stage disease if it is macroscopically involved.

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    36 patients with advanced cervical carcinoma stage III (24 patients) and stage IV (12 patients) entered a feasibility study of a radiotherapy and chemotherapy combination. The first three chemotherapy courses consisted of cis-platinum alone and were interdigitated with radiotherapy. Six more courses composed of an association of cis-platinum and cyclophosphamide were given after the completion of radiotherapy. Radiotherapy was delivered in two courses of 25 Gy separated by a gap of 2 weeks. The overall 4-year survival rate, cumulative loco-regional failure rate, and cumulative meatstasis rate were respectively 44%, 56% and 30% in stage III and 28%, 83% and 74% in stage IV. The incidence of immediate and late complications was low: no patient had her radiotherapy stopped because of an intolerance and two patients had their chemotherapy stopped because of an haematological intolerance. Only one patient presented a severe late clinical complication (small bowel injury). 29 refs.; 2 figs.; 4 tabs

    Purpose: To evaluate toxicity, local tumor control, and survival after preoperative chemoradiation for operable bulky cervical carcinoma. Methods and Materials: Between December 1991 and July 2006, 92 patients with operable bulky stage IB2, IIA, and IIB cervical carcinoma without pelvic or para-aortic nodes on pretreatment imaging were treated. Treatment consisted of preoperative external beam pelvic radiation therapy (EBRT) and concomitant chemotherapy (CT) during the first and fourth weeks of radiation combining 5-fluorouracil and cisplatin. The pelvic radiation dose was 40.5 Gy over 4.5 weeks. EBRT was followed by low-dose rate uterovaginal brachytherapy with a total dose of 20 Gy in 62 patients. After a median rest period of 44 days, all patients underwent Class II modified radical hysterectomy with bilateral pelvic lymphadenectomy. Thirty patients who had not received preoperative uterovaginal brachytherapy underwent postoperative low-dose-rate vaginal brachytherapy at a dose of 20 Gy. The mean follow-up was 46 months. Results: Pathologic residual tumor was observed in 43 patients. After multivariate analysis, additional preoperative uterovaginal brachytherapy was the single significant predictive factor for pathologic complete response rate (p = 0.019). The 2- and 5-year disease-free survival (DFS) rates were 80.4% and 72.2%, respectively. Pathologic residual cervical tumor was the single independent factor decreasing the probability of DFS (p = 0.020). Acute toxicities were moderate. Two severe ureteral complications requiring surgical intervention were observed. Conclusions: Concomitant chemoradiation followed by surgery for operable bulky stage I-II cervical carcinoma without clinical lymph node involvement can be used with acceptable toxicity. Pathologic complete response increases the probability of DFS

    The AIM of this retrospective study is to analyse the indications and the results of treatment of endometrial carcinomas by preoperative radiotherapy. MATERIAL: From 1976 to 1995, 183 patients FIGO stage I or II were treated by preoperative radiotherapy consisting in 95 cases of external radiotherapy (XRT) and brachytherapy (BT) followed by surgery (S) and, in 88 cases of BT alone before surgery, XRT was indicated in cases of grade 2 or 3 and/or cervical involvement. METHODS: XRT was delivered with a 4-fields technique to 40 Gy in 20 fractions with a medial shielding at 30 Gy. BT was done with low dose rate Cs137 and Fletcher-Suit-Delclos applicators with two intra-uterine tubes and vaginal ovoieds. Complications were scored using the French-Italian syllabus. RESULTS: Five-year actuarial survival rates per stage are: Ia=91%, Ib=83%, II=71%, and per grade: G1=80%, G2=79%, G3=90%. Failures were pelvic in 5/183 (2.7%), vaginal in 4 cases (2%) and nodal in 2 cases (1%). Twelve patients developed metastases (6.5%). Complications were analysed during the radiotherapy, after the surgery and with unlimited follow-up. After BT/S, 12 grade 1, 1 grade 2 and 1 grade 3 complications were observed. In the group of patients treated by RT/BT/S, 22 grade 1, 11 grade 2, 4 grade 3 occurred. There is no statistical correlation between complications and parameters of treatment (XRT, hwt, HWT, reference dose to the bladder and rectum, dose rate of brachytherapy). SUMMARY: Preoperative irradiation is an effective and safe treatment of high risk stage I/II endometrial carcinomas. Results seem independent of the pathology grade

    Purpose: Blood perfusion in tumors is spatially and temporally heterogeneous, resulting in local fluctuations in tissue oxygen tension (pO{sub 2}) and tissue regions showing cycling hypoxia. In this study, we investigated whether the pO{sub 2} fluctuation pattern and the extent of cycling hypoxia differ between tumor types showing high (e.g., cervical carcinoma xenograft) and low (e.g., melanoma xenograft) fractions of connective tissue-associated blood vessels. Methods and Materials: Two cervical carcinoma lines (CK-160 and TS-415) and two melanoma lines (A-07 and R-18) transplanted into BALB/c nu/nu mice were included in the study. Tissue pO{sub 2} was measured simultaneously in two positions in each tumor by using a two-channel OxyLite fiber-optic oxygen-sensing device. The extent of acute and chronic hypoxia was assessed by combining a radiobiological and a pimonidazole-based immunohistochemical assay of tumor hypoxia. Results: The proportion of tumor regions showing pO{sub 2} fluctuations, the pO{sub 2} fluctuation frequency in these regions, and the relative amplitude of the pO{sub 2} fluctuations were significantly higher in the melanoma xenografts than in the cervical carcinoma xenografts. Cervical carcinoma and melanoma xenografts did not differ significantly in the fraction of acutely hypoxic cells or the fraction of chronically hypoxic cells. However, the ratio between fraction of acutely hypoxic cells and fraction of chronically hypoxic cells was significantly higher in melanoma than in cervical carcinoma xenografts. Conclusions: Temporal heterogeneity in blood flow and tissue pO{sub 2} in tumors may depend on tumor histology. Connective tissue surrounding microvessels may stabilize blood flow and pO{sub 2} and, thus, protect tumor tissue from cycling hypoxia.

    Objective: To analyze the results of neck dissection in patients who failed in cervical lymph nodes after radiotherapy for nasopharyngeal carcinoma. Methods: Eighty-three patients who received neck dissection due to lymph node persistence or recurrence after definitive radiotherapy were analyzed retrospectively according to the following relevant factors: age, sex, the interval between completion of radiotherapy and surgery, rN stage, postoperative radiotherapy given or not, the adjacent tissues involved or not and the number of positive nodes. Kaplan-Meier method, Log-rank method and Cox method were used in the statistical analysis. Results: The 1-, 3- and 5-year overall survival rates were 80.7%, 47.1% and 34.9%. The interval between completion of radiotherapy and surgery, postoperative radiotherapy given or not, the adjacent tissues involved or not were significantly prognostic factors in statistic analysis. Conclusions: Neck dissection can be applied in the management of cervical lymph node failure in nasopharyngeal carcinoma after radiotherapy. Postoperative radiotherapy should be considered in patients with capsular invasion and/or adjacent tissue involvement

    Highlights: Black-Right-Pointing-Pointer Upregulation of Skp2 by IL-6 or Stat3 activation. Black-Right-Pointing-Pointer Stat3 activates Skp2 expression through bound to its promoter region. Black-Right-Pointing-Pointer Stat3 activates Skp2 expression through recruitment of P300. Black-Right-Pointing-Pointer Stat3 activation decreases the P27 stability. -- Abstract: Dysregulated Skp2 function promotes cell proliferation, which is consistent with observations of Skp2 over-expression in many types of human cancers, including cervical carcinoma (CC). However, the molecular mechanisms underlying elevated Skp2 expression have not been fully explored. Interleukin-6 (IL-6) induced Stat3 activation is viewed as crucial for multiple tumor growth and metastasis. Here, we demonstrate that Skp2 is a direct transcriptional target of Stat3 in the human cervical carcinoma cells. Our data show that IL-6 administration or transfection of a constitutively activated Stat3 in HeLa cells activates Skp2 mRNA transcription. Using luciferase reporter and ChIP assays, we show that Stat3 binds to the promoter region of Skp2 and promotes its activity through recruiting P300. As a result of the increase of Skp2 expression, endogenous p27 protein levels are markedly decreased. Thus, our results suggest a previously unknown Stat3-Skp2 molecular network controlling cervical carcinoma development.

Patients and methods: The study period was from June 2002 to March 2014. The subjects were 28 patients with a stage II bulky mass in the NAC group and 17 such patients in the Ope group. The chi-square test was used to compare operative time, volume of intraoperative blood loss, use of blood transfusion, and time from surgery to discharge between the two groups. Moreover, the log-rank test using the Kaplan–Meier method was performed to compare disease-free survival (DFS and overall survival (OS between the groups. Results: There were no statistically significant differences between the two groups in operative time, volume of intraoperative blood loss, or use of blood transfusion. However, the time from surgery to discharge was 18 days (14–25 days in the NAC group and 25 days (21–34 days in the Ope group; the patients in the NAC group were discharged earlier (P=0.032. The hazard ratio for DFS in the NAC group as compared with that in the Ope group was 0.36 (95% CI 0.08–0.91, and the 3-year DFS rates were 81.2% and 41.0%, respectively (P=0.028. Moreover, the hazard ratio for OS was 0.39 (95% CI 0.11–1.24, and the 3-year OS rates were 82.3% and 66.4%, respectively (P=0.101. Conclusion: NAC with cisplatin and irinotecan was confirmed to prolong DFS as compared with RH alone. The results of this study suggest that NAC might be a useful adjunct to surgery in the treatment of stage II squamous

    Carcinoma cervix accounts for 86-90% of all genital cancers in Indian women. This is presented with prolonged infection and impairment of immune response even after completing the radiation therapy protocol. Increase in expression of IL-6 gene in invasive cervical carcinoma was observed against CIN and normal cervix. Evaluation of infiltrating lymphocytes TIL showed considerable CD3 + and CD4 + expression which predicted better prognosis and improved survival that was negated by increased IL-6. (author)

    Squamous cell carcinoma (SCC) of the oral tongue and floor of mouth are the most common head and neck cancers. Regional metastasis of SCC is most likely found at the cervical lymph node. Size and characteristics of pathologically suspicious lymph nodes are related to the aggressiveness of the primary tumor: The objective of this study is to analyze the conrrelation between sizes of cervical node and metastasis in SCC of oral tongue and floor of mouth. Retrospective review was conducted firom the patient's charts between January 2008 and December 2012. Clinical, histopathology and surgical records were reviewed. Cervical lymph nodes ofSCC of oral tongue and floor of mouth were reviewed and divided into four groups depending on their size (1-5 mm, 6-9 mm, 10-30 mm and more than 30 am,). A p-value oral cavity were recorded. Sixteen patients ofSCC of the oral tongue and 15patients of SCC of the floor of mouth underwent neck dissection (641 cervical nodes). Most ofthe patients were diagnosed with stage 3 (41.94%). Extracapsular extension was found in 72.15% of SCC of oral tongue and 73.33 % of SCC ofthe floor of mouth. Size of cervical lymph nodes less than 10 mm was found to be metastasis at 9.27% and 10.82% of SCC of oral tongue and floor of mouth, respectively. Cervical node metastasis can be found in SCC of the oral tongue and floor ofmouth with clinlically negative node andsize of cervical node less than 10 mm. Here in, size of cervical node less than 10 mm was still important due to the chance for metastasis especially high grade tumors, advanced stage cancer and lymphovascular invasion.

    Sixty-two patients with cervical carcinoma were treated in 1966 to 1968. Thirty-two patients who were alive in 1982 were reevaluated concerning intestinal function. An initial low folate value associated with the disease did not correlate with prognosis. A late low folate value indicated malabsorption and not recurrence of the carcinoma. Malabsorption was found in 5/23 patients (22%) and 3 of these (13%) had vitamin B 12 deficiency. Intestinal damage in tumour free patients occurred in 2/62 (3%) patients. It is suggested that late silent complications such as malabsorption should be looked for in the preventive care of these patients. (Auth.)

    Two recurrent mutations (-124 G > A and -146 G > A) in the core promoter region of the human telomerase reverse transcriptase (TERT) gene create consensus binding sites for ETS transcription factors and cause increased TERT expression in several tumour types. We analyzed TERT promoter mutations and TERT mRNA levels in head and neck cancer, cervical carcinoma and cervical intraepithelial neoplasia (CIN) as well as in C-4I, CaSki, HeLa and SiHa cervical cell lines. Nucleotide sequence analysis of TERT promoter region showed that 33.3% of oral squamous cell carcinoma (SCC) and 16.8% of cervical SCC harboured mutually exclusive G to A transitions at nucleotide position -124 or -146. TERT promoter was mutated at nucleotide -146 (G > A) in SiHa cell line. Other nucleotide changes creating in some cases putative ETS binding sites were more frequent in oral SCC (26.7%) than in cervical carcinoma (4.8%). The frequency of mutations was independent of human papillomavirus (HPV) tumour status in both cervical and oral cancer. Expression of TERT gene was significantly higher in TERT promoter mutated (-124G > A or -146G > A) cervical SCC compared to not mutated SCC irrespective of HPV16 E6 and E7 levels. Such hot spot changes were not detected in oropharyngeal SCC, cervical adenocarcinoma and CIN lesions. Our results suggest that TERT promoter mutations play a relevant role in oral SCC as well as in cervical SCC, besides the already known effect of HPV16 E6 protein on TERT expression. © 2018 UICC.

    Polarization imaging has been recognized as a potentially powerful technique for probing the microstructural information and optical properties of complex biological specimens. Recently, we have reported a Mueller matrix microscope by adding the polarization state generator and analyzer (PSG and PSA) to a commercial transmission-light microscope, and applied it to differentiate human liver and cervical cancerous tissues with fibrosis. In this paper, we apply the Mueller matrix microscope for quantitative detection of human breast ductal carcinoma samples at different stages. The Mueller matrix polar decomposition and transformation parameters of the breast ductal tissues in different regions and at different stages are calculated and analyzed. For more quantitative comparisons, several widely-used image texture feature parameters are also calculated to characterize the difference in the polarimetric images. The experimental results indicate that the Mueller matrix microscope and the polarization parameters can facilitate the quantitative detection of breast ductal carcinoma tissues at different stages.

    Background: Human papillomavirus (HPV) types 16 and 18 are associated with cervical carcinogenesis. This is possibly achieved through an interaction between HPV oncogenic proteins and some cell cycle regulatory genes. However, the exact pathogenetic mechanisms are not well defined yet. Methods: We investigated 110 subjects (43 invasive squamous cell carcinoma [ISCC], 38 CIN Ill, II CIN II, 18 CIN I) confirmed to be positive for HPV 16 and/or 18 as well as 20 normal cervical tissue (NCT) samples for abnormal expression of cyclin DJ, cyclin E, CDK4, cyclin inhibitors (p2Jwa/; p27, pI6/NK4A) and Ki-67 using immunohistochemistry and differential PCR techniques. Results: There was a significant increase in the expression of Ki-67, cyclin E, CDK4, pJ6/NK4A (p=0003, 0.001,0.001) and a significant decrease in p27K1P/ from NCT to ISCC (p=0.003). There was a significant correlation between altered expression of p27K1P I and p 161NK4A (p KIpl (ρ=0.011) in all studied groups In ISCC, there was significant relationship between standard clinico-pathological prognostic factors and high Ki-67 index, increased cyclin D J and cyclin E, reduced p2 7Kip / and p21 waf Conclusion: I) Aberrations involving p27K/P 1, cyclin E, CDK4 and pJ6/NK4A are considered early events in HPV 16 and IS-associated cervical carcinogenesis (CINI and lI), whereas cyclin DI aberrations are late events (CINIII and ISCC). 2) immunohistochemical tests for pJ61NK4A and cyclin E could help in early diagnosis of cervical carcinoma. 3) Only FIGO stage, cyclin DI, p27K1P1 and Ki-67 are independent prognostic factors that might help in predicting outcome of cervical cancer palients

    Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

    Objective: To determine the value and limitation of water enema spiral CT (WESCT) in staging of colorectal carcinoma. Methods: Forty-eight patients with histologically proven rectum or colon carcinoma were included in this study. All of them were examined by SCT, and the preoperative staging of TNM and Duke were used based on the findings of SCT. The results of WESCT were compared with those of surgical and pathological examination in all cases. Results: All lesions in the 47 cases were demonstrated clearly by WESCT and the sensitivity was 97.9%; 39 cases of 48 patients were correctly staged with TNM and 42 cases with Duke, the accuracy was 81.3% and 87.5% respectively, which were higher than the overall 50 % accuracy reported by references; (3) The accuracy of WESCT was 89.6% (43/48) in T stage and 81.3% (39/48) in N stage. Three cases in M stage were all diagnosed correctly; Conclusion: WESCT scan is a better method of depicting the colorectal carcinoma. It allows for accurate depiction and staging of colorectal carcinoma, especially detecting the invasion of adjacent tissues and distant metastasis. It is the best imaging method for staging the colorectal carcinoma . However the value of WESCT for early T staging in colorectal carcinoma and minute metastasis of lymph nodes or liver is limited

    Full Text Available Matrix metalloproteinases (MMPs, a family of proteolytic enzymes produced by both stromal and tumor cells, appear to have a key role in the events leading to local invasion and metastasis by malignant neoplasms. In the present study, we evaluated the role of MMP-2, squamous cell carcinoma antigen (SCCA, and tissue polypeptide – specific antigen (TPS in cervical neoplasia. Using Western blotting and enzyme immunoassay (EIA, we analyzed 50 patients with cervical carcinoma (CC and 25 normal controls for expression of MMP-2 in tissue cell lysates. We also quantified SCCA and TPS with microparticle immunoassay and EIA, respectively. The results were correlated with human papilloma virus (HPV infection, clinicopathological findings, and disease outcome. The cutoff point for each marker was estimated from receiver operating characteristic curves. Logistic regression analysis was performed to estimate the odds ratio (OR and 95% confidence interval (CI for each marker. MMP-2, SCCA, and TPS protein expression were significantly higher in patients with CC than in normal controls. While TPS was the best marker for discriminating between patients and controls, MMP-2 was associated with an advanced tumor stage (OR, 13.9 [95% CI, 1.4-133.9] and poor histological grade (OR, 10.2 [95% CI, 1.7-60.5]. Moreover, independent of the effect of an advanced CC stage and grade, the patients' age, and the presence of HPV infection, MMP-2 was considered a strong predictor for CC recurrence (OR, 8.1 [95% CI, 1.3- 49.1]. Tissue markers may be used to select high-risk patients for early detection of and adjuvant therapy for recurrence. Our MMP-2 findings are particularly relevant to the development of protease inhibitors as a new cancer therapy approach.

    Advanced-stage diagnosis is among the primary causes of mortality among cervical cancer patients. With the wide use of Pap smear screening, cervical cancer advanced-stage diagnosis rates have decreased. However, disparities of advanced-stage diagnosis persist among different population groups. A challenging task in cervical cancer disparity reduction is to identify where underserved population groups are. Based on cervical cancer incidence data between 1995 and 2008, this study investigated advanced-stage cervical cancer disparities in Texas from three social domains: Race/ethnicity, socioeconomic status (SES), and geographic location. Effects of individual and contextual factors, including age, tumor grade, race/ethnicity, as well as contextual SES, spatial access to health care, sociocultural factors, percentage of African Americans, and insurance expenditures, on these disparities were examined using multilevel logistic regressions. Significant variations by race/ethnicity and SES were found in cervical cancer advanced-stage diagnosis. We also found a decline in racial/ethnic disparities of advanced cervical cancer diagnosis rate from 1995 to 2008. However, the progress was slower among African Americans than Hispanics. Geographic disparities could be explained by age, race/ethnicity, SES, and the percentage of African Americans in a census tract. Our findings have important implications for developing effective cervical cancer screening and control programs. We identified the location of underserved populations who need the most assistance with cervical cancer screening. Cervical cancer intervention programs should target Hispanics and African Americans, as well as individuals from communities with lower SES in geographic areas where higher advanced-stage diagnosis rates were identified in this study.

    Human Papillomavirus (HPV) genotype distribution and co-infection occurrence was studied in cervical specimens from the city of Madrid (Spain), as a contribution to the knowledge of Human Papillomavirus genotype distribution and prevalence of carcinogenic HPV types in cervical lesions in Spain. A total of 533 abnormal specimens, from the Hospital General Universitario “Gregorio Marañón” of Madrid, were studied. These included 19 benign lesions, 349 cervical intraepithelial neoplasias 1 (CIN1), 158 CIN2-3 and 7 invasive cervical carcinomas (ICC). HPV genotyping was performed using PCR and tube array hybridization. We detected 20 different HPV types: 13 carcinogenic high-risk HPV types (HR-HPVs), 2 probably carcinogenic high-risk HPV types (PHR-HPVs) and 5 carcinogenic low-risk HPV types (LR-HPVs). The most frequent HPV genotypes found in all specimens were HPV16 (26.0%), 31 (10.7%) and 58 (8.0%). HPV 18 was only detected in 5.0%. Co-infections were found in 30.7% of CIN 1 and 18.4% cases of CIN2-3. The highest percentage of HR HPVs was found in those specimens with a CIN2-3 lesion (93.7%). As our study shows the current tetravalent vaccine could be effective in our geographical area for preventing all the invasive cervical carcinomas. In addition, upon the estimates of the important presence of other HR-HPV types – such as 31, 58, 33 and 52 – in different preneoplasic lesions the effectiveness of HPV vaccination in our geographical area, and others with similar genotype distribution, should be limited

    In a prospective study by the Gynecologic Oncology Group (GOG), 104 evaluable patients with cervical squamous cell carcinoma Stages IIIB and IVA were randomly assigned to treatment with hydroxyurea or placebo in combination with radiation. There were no deaths resulting from the treatment. Hematologic toxicity was more common and more severe in patients who received hydroxyurea. Response was evaluated in terms of complete tumor regression, duration of progression-free interval, and survival probability. By all those parameters the response was significantly better in the groups of patients receiving hydroxyurea

    PMS2 expression loss was reported in a variety of human. However, its importance has not been fully understood in cervical carcinoma. The aim of this study was to determine the expression of PMS2 in cervical carcinoma and evaluate the significance of mismatch repair gene PMS2 regulated by glycogen synthase kinase 3beta (GSK-3beta) in chemosensitivity. We examined PMS2 and phosphorylated GSK-3beta(s9) expression in cervical carcinoma tissues using immunohistochemical staining. Furthermore, we detected PMS2 expression in HeLa cells and evaluate the interaction with GSK-3beta after transfection with GSK-3beta by small interference RNA (siRNA), co-immunoprecipitation and immunoblotting. We also evaluated the effect of PMS2 transfection on HeLa cells' chemosensitivity to cisplatin treatment. We found significant downregulation of PMS2 in cervical carcinoma, which was negatively associated with phosphorylated GSK-3beta (s9). Furthermore, we demonstrated GSK-3beta transfection was able to interact with PMS2 and enhance PMS2 production in HeLa cells, and increased PMS2 production was responsible for enhanced chemosensitivity. Our results provide the evidence that stabilization of PMS2 production by GSK-3beta was important to improve chemosensitization, indicating the significance of GSK-3beta-related PMS2 downregulation in the development of cervical carcinoma and in developing a potential strategy for chemotherapy.

    Purpose:We evaluated the effects of intra-arterial infusion therapy by comparing the results obtained with a combination of intra-arterial anticancer drugs with and without transcatheter arterial embolization (TAE) in patients with cervical cancer.Methods:Between April 1999 and March 2003, intra-arterial therapy was administered to 45 patients (mean age 49 years) with cervical cancer. Of these, 18 had stage IIb , 4 had stage IIIa, 19 had stage IIIb, and 4 had stage IVb cancer; the histopathologic types were squamous cell carcinoma (n = 35), adenocarcinoma (n = 8), and adenosquamous carcinoma (n = 2). A total of 45 patients gave their informed consent and were randomized on a continuous basis into one of three groups according to the therapeutic protocols: group A consisted of 15 patients who received cisplatin, group B consisted of 17 patients who received cisplatin, mitomycin, doxorubicin hydrochloride, and 5-fluorouracil, and group C consisted of 13 patients who received cisplatin and TAE. Each protocol was administered twice with a 3 week interval between treatments. The efficacy of treatment was evaluated on the basis of the tumor reduction ratio (%) using MR imaging and the side effects were analyzed.Results:In groups A, B, and C, the tumor reduction ratio was 54%, 84%, and 86%, respectively; it was significantly greater in groups B and C than in group A (p < 0.01). The difference between groups B and C was not statistically significant. Although all group C patients developed severe pain after TAE, the pain was controlled with analgesics. Thrombocytopenia occurred in 6 of 17 (35%) group B patients.Conclusion:Group B and C patients had better tumor reduction than those in group A. Fewer hematologic complications occurred in group C patients compared with group B

    Bmi-1, a putative proto-oncogene, is a core member of the polycomb gene family, which is expressed in many human tumors. The p16 protein negatively regulated cell proliferation, whereas CD44v6 is associated with proliferation as an important protein. Additionally, CD44v6 is an important nuclear antigen closely correlated to tumor metastasis. The present study aims to investigate the expression and significance of Bmi-1, p16, and CD44v6 in uterine cervical carcinoma (UCC). A total of 62 UCC, 30 cervical neoplasic, and 20 normal cervical mucosal tissues were used in the current study. The expression of Bmi-1, p16, and CD44v6 in these tissues was determined using immunohistochemical assay. The relationships among the expression of these indices, the clinicopathologic features of UCC, and the survival rate of UCC patients were also discussed. The correlation between Bmi-1 protein expression and p16 or CD44v6 protein in UCC was analyzed. The expression of Bmi-1, p16, and CD44v6 was significantly high in cervical carcinoma compared with that in the cervical neoplasia and normal colorectal mucosa (P<0.05). The over-expression of Bmi-1 protein in UCC was apparently related to the distant metastasis (P<0.01) and the tumor, nodes and metastasis-classification, i.e. the TNM staging, World Health Organization (P<0.05). Nevertheless, the positive expression of p16 protein in UCC was not significantly associated with the clinicopathologic features (P>0.05). The Kaplan–Meier survival analysis showed that the over-expression of Bmi-1 significantly decreased the survival rate of UCC patients (P<0.05). A strong correlation indicated that there was statistical significance between the expression of Bmi-1 and CD44V6 proteins in UCC (r=0.419, P=0.001). The over-expression of Bmi-1 and CD44v6 protein closely correlate to the tumorigenesis, metastasis, and prognosis of UCC. Bmi-1 and CD44v6 may be used to predict the prognosis of cervical carcinoma. Bmi-1 may indirectly regulate the

    Currently cervical cancer represents approximately 4 % of all cancer diagnoses, being the seventh most common cancer (1, 2). The standard management of patients with early cervical carcinoma is surgical treatment. Chemo radiation therapy is accepted as a standard of care for locally advanced disease (>= II B). Concurrent chemotherapy (usually cisplatin based) produced significantly improved survival and local relapse rates. The future development will be based on the improvement of sexual education, prevention and therapeutical modalities. (author)

    Background and purpose: The management of lymphatic metastasis of early-stage oral tongue carcinoma patients is crucial for its prognosis. The purpose of this study was to evaluate the predictive ability of lymphatic metastasis after brachytherapy (BRT) for early-stage tongue carcinoma based on gene expression profiling. Patients and methods: Pre-therapeutic biopsies from 39 patients with T1 or T2 tongue cancer were analyzed for gene expression signatures using Codelink Uniset Human 20K Bioarray. All patients were treated with low dose-rate BRT for their primary lesions and underwent strict follow-up under a wait-and-see policy for cervical lymphatic metastasis. Candidate genes were selected for predicting lymph-node status in the reference group by the permutation test. Predictive accuracy was further evaluated by the prediction strength (PS) scoring system using an independent validation group. Results: We selected a set of 19 genes whose expression differed significantly between classes with or without lymphatic metastasis in the reference group. The lymph-node status in the validation group was predicted by the PS scoring system with an accuracy of 76%. Conclusions: Gene expression profiling using 19 genes in primary tumor tissues may allow prediction of lymphatic metastasis after BRT for early-stage oral tongue carcinoma

    Introduction: The objective of this trial is to investigate the diagnostic value of magnetic resonance imaging (MRI) with an endorectal surface coil for precise local staging of patients with histologically proven cervical cancer by comparing the radiological, clinical, and histological results. Materials and methods: Women with cervical cancer were recruited for this trial between February 2007, and September 2010. All the patients were clinically staged according to the FIGO classification and underwent radiological staging by MRI that employed an endorectal surface coil. The staging results after surgery were compared to histopathology in all the operable patients. Results: A total of 74 consecutive patients were included in the trial. Forty-four (59.5%) patients underwent primary surgery, whereas 30 (40.5%) patients were inoperable according to FIGO and underwent primary radiochemotherapy. The mean age of the patients was 50.6 years. In 11 out of the 44 patients concordant staging results were obtained by all three staging modalities. Thirty-two of the 44 patients were concordantly staged by FIGO and histopathological examination, while only 16 were concordantly staged by eMRI and histopathological examination. eMRI overstaged tumors in 14 cases and understaged them in 7 cases. Conclusions: eMRI is applicable in patients with cervical cancer, yet of no benefit than staging with FIGO or standard pelvic MRI. The most precise preoperative staging procedure still appears to be the clinical examination

    Full Text Available Evaluation of skeletal age and determination of growth status had important and special roie in orthodontic treatment planning (such as functional orthopedic treatment and orthognatic surgery and also in stability of it. There were several biologic indicators for the detection of the peak in mandibular growth. Due to the limitations of biological indicators application, idea of new indicators was seemed importantly. Cervical vertebral maturation (CVM method is one of them. At first the detection of the peak in mandibular growth was based on the analysis of the second through sixth cervical vertebrae in six developmental stages. But a few improvements of the original CVM analysis were still needed. In this method, the peak in mandibular growth was determined based on the analysis of the second through fourth cervical vertebrae in five developmental stages. This method is easy, applicable and more valid than hand-wrist analysis method.

    A phase II trial was performed to evaluate the efficacy and toxicity of a combination of cisplatin (CDDP) and ifosfamide (IFX) as neoadjuvant chemotherapy in advanced cervical carcinoma (ACC). Between August 1991 and September 1993, 57 untreated patients with stages IIB to IVA were entered into this study. Median age was 44 years (range, 25 to 74 years). The distribution by stages (International Federation of Gynecology and Obstetrics) was as follows: IIB, 31 patients; IIIB, 21 patients; and IVA, 5 patients. Therapy consisted of IFX 2000 mg/m(2) 1-h i.v. infusion days 1 to 3; mesna 400 mg/m(2) i.v. bolus at hours 0 and 4, and 800 mg p.o. at hour 8; and CDDP 100 mg/m(2) on day 3. Cycles were repeated every 28 days for a total of three courses. Both staging and response assessment were performed by a multidisciplinary team. An objective response was observed in 30 of 56 patients (54%; 95% confidence interval, 41 to 67%). Four patients (7%) had a complete response (CR) and 26(46%) had a partial response (PR). Patients with CR or operable PR underwent surgery, otherwise received definitive radiotherapy. Toxicity was mild to moderate. There were no toxicity related deaths. These results indicate that IFX/CDDP is an active combination for ACC with mild toxicity. The results of phase III studies that evaluate the real impact of neoadjuvant chemotherapy are awaited.

    Proteasomal degradation of p53 by human papilloma virus (HPV) E6 oncoprotein plays a pivotal role in the survival of cervical carcinoma cells. Abrogation of HPV-E6-dependent p53 destruction can therefore be a good strategy to combat cervical carcinomas. Here, we show that a small-molecule reactivation of p53 and induction of tumor cell apoptosis (RITA) is able to induce the accumulation of p53 and rescue its tumor suppressor function in cells containing high-risk HPV16 and HPV18 by inhibiting HPV-E6-mediated proteasomal degradation. RITA blocks p53 ubiquitination by preventing p53 interaction with E6-associated protein, required for HPV-E6-mediated degradation. RITA activates the transcription of proapoptotic p53 targets Noxa, PUMA, and BAX, and repressed the expression of pro-proliferative factors CyclinB1, CDC2, and CDC25C, resulting in p53-dependent apoptosis and cell cycle arrest. Importantly, RITA showed substantial suppression of cervical carcinoma xenografts in vivo. These results provide a proof of principle for the treatment of cervical cancer in a p53-dependent manner by using small molecules that target p53. (c)2010 AACR.

    Full Text Available Abstract Background PMS2 expression loss was reported in a variety of human. However, its importance has not been fully understood in cervical carcinoma. The aim of this study was to determine the expression of PMS2 in cervical carcinoma and evaluate the significance of mismatch repair gene PMS2 regulated by glycogen synthase kinase 3β (GSK-3β in chemosensitivity. Methods We examined PMS2 and phosphorylated GSK-3β(s9 expression in cervical carcinoma tissues using immunohistochemical staining. Furthermore, we detected PMS2 expression in HeLa cells and evaluate the interaction with GSK-3β after transfection with GSK-3β by small interference RNA (siRNA, co-immunoprecipitation and immunoblotting. We also evaluated the effect of PMS2 transfection on HeLa cells' chemosensitivity to cisplatin treatment. Results We found significant downregulation of PMS2 in cervical carcinoma, which was negatively associated with phosphorylated GSK-3β (s9. Furthermore, we demonstrated GSK-3β transfection was able to interact with PMS2 and enhance PMS2 production in HeLa cells, and increased PMS2 production was responsible for enhanced chemosensitivity. Conclusions Our results provide the evidence that stabilization of PMS2 production by GSK-3β was important to improve chemosensitization, indicating the significance of GSK-3β-related PMS2 downregulation in the development of cervical carcinoma and in developing a potential strategy for chemotherapy.

    Purpose: Radiotherapy is a curative option in the treatment of early stage cervical carcinoma and radioresistant tumors limit local control and survival. Therefore, it is important to understand mechanisms by which cells evade death after irradiation. Of these, the process of apoptosis offers a useful model system to study. Tumors of the cervix offer a unique opportunity in that most contain an HPV genome expressing the E6 and E7 gene products under the control of a glucocorticoid responsive promoter. The HPV E6 and E7 proteins target p53 and/or Rb, both of which are involved in cell cycle control and in the apoptotic process. It was previously determined that treatment with the corticosteroid dexamethasone increased transcription of E6 and E7 and decreased p53 protein levels which corresponded with increased radioresistance and decreased apoptosis in C4-1 cervical carcinoma cells. The goal of this study is to demonstrate pharmacological manipulation of apoptosis within an HPV +ve cervical cell line. Methods: The HPV 18 +ve and p53 wildtype human cervical cell line C4-1 was used in this study. Apoptosis was induced by exposure to 6 Gy of gamma radiation and the ability of cells to undergo apoptosis was determined by morphology and the ability to form internucleosomal fragments using a DNA laddering technique. Cells were exposed to 0.01 to 1 μM dexamethasone in the presence or absence of 1 μM Mifepristone (RU486), a steroid antagonist and analyzed using the DNA laddering assay. In addition, cells that were irradiated in the presence of dexamethasone and/or Mifepristone were collected and p53 protein levels determined by FACS analysis. Results: Apoptosis was observed at a low level in control cells and was increased by irradiation with 6 Gy as determined by DNA laddering and morphology. The presence of 0.01 to 1 μM dexamethasone reduced both the radiation induced DNA laddering and also that seen in control cells. Addition of 1 μM Mifepristone to dexamethasone

    Full Text Available Background: Treatment effectiveness and clinical outcome of patients with cervical carcinoma FIGO stage IA1 and IA2 are analyzed in three different time period at the Department of Obstetrics and Gynecology Rijeka, Croatia. Method: Retrospective analysis of the hospital chart of all cervical cancer patients between 1991 and 2005 was conducted with five-year follow up. Results: Data on cervical cancer distribution by stage and five-year survival are presented. Separately analyzed age, histology type and treatment modalities in stage FIGO IA1 and IA2 during three consecutive five-year periods are presented. Conclusions: Conservative surgical approach – conization alone in stage IA1 of the squamous cell car- cinoma is reasonable and safe treatment option for reproductive active women. During observed periods conization became the most used surgical technique applied in almost two third of FIGO IA1 cervical cancer patients. Lymph vascular space invasion in stage IA1 lead to adjunct pelvic lymphadenectomy with unclear clinical benefit. In cervical cancer patients stage IA2 simple hysterectomy and pelvic lymphadenectomy could be accepted as a standard treatment. In these patients further studies are recommended to evaluate other less radical surgical techniques – simple and radical trachelectomy with or without pelvic lymphadenectomy. Radical hysterectomy in both stages IA1 and IA2, based on personal experience and literature data represents a surgical overtreatment and should be abandoned.

    Full Text Available To determine the prognostic significance of unilateral cervical lymph nodal metastasis (CLNM in patients with inoperable thoracic esophageal squamous cell carcinoma (SCC and to identify significant prognostic factors in these patients.This retrospective study involved 395 patients with inoperable esophageal SCC treated with concurrent chemoradiotherapy. The patients were classified into three groups according to their cervical lymph node status: group A, no evidence of CLNM; group B, unilateral CLNM; group C, other distant metastases. Overall survival (OS and progression-free survival (PFS were calculated. Significant prognostic factors were identified using univariate and multivariate analyses.The 3-year OS rates in groups A, B and C were 46.7%, 33.5% and 8.3%, respectively (p<0.001, log-rank test. The corresponding PFS rates were 40.7%, 26.4% and 4.7% (p<0.001, log-rank test. Group B had a similar prognosis to that of group A and better 3-year OS (p = 0.009 and PFS (p = 0.006 rates than those of group C. Multivariate analysis demonstrated that T stage, chemotherapy regimen and cervical lymph node involvement were independent prognostic factors affecting OS and PFS.Compared to other distant metastases, unilateral CLNM is associated with longer OS in esophageal SCC and should be regarded as a regional disease. Sex, T stage, concurrent chemotherapy modality and cervical lymph node involvement are independent predictors of survival in esophageal SCC.

    To evaluate MR capacity in assessing deep myometrial and cervical infiltrations in cases of endometrial carcinoma. A series of 30 consecutively diagnosed endometrial cancer patients was pre-surgically evaluated by means of magnetic resonance (MR). TSE-T2 sequences with fat saturation and dynamic FFe sequence were used after gadolinium administration. A correlation with post-surgical histological stating was made. There were then determined sensitivity (S), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) for the deep myometrial infiltration and cervical invasion. Cases of overestimation and underestimation were analyzed. Values obtained for myometrium and cervix were, respectively, S of 67% and 63%, SP of 89% and 91%, PPV of 80% and 71% and NPV of 80% and 87%. Two cases each were over valued for myometrial infiltration and cervix: four cases and 3 cases, respectively, were undervalues. MR stating in cases of endometrial carcinoma is a highly reliable diagnostic technique, but it does present certain limitations. (Author) 19 refs

    2012-11-01

    Full Text Available Abstract Background High interstitial fluid pressure (IFP in the primary tumor is associated with poor disease-free survival in locally advanced cervical carcinoma. A noninvasive assay is needed to identify cervical cancer patients with highly elevated tumor IFP because these patients may benefit from particularly aggressive treatment. It has been suggested that dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI with gadolinium diethylene-triamine penta-acetic acid (Gd-DTPA as contrast agent may provide useful information on the IFP of cervical carcinomas. In this preclinical study, we investigated whether DCE-MRI with contrast agents with higher molecular weights (MW than Gd-DTPA would be superior to Gd-DTPA-based DCE-MRI. Methods CK-160 human cervical carcinoma xenografts were subjected to DCE-MRI with Gd-DTPA (MW of 0.55 kDa or gadomelitol (MW of 6.5 kDa as contrast agent before tumor IFP was measured invasively with a Millar SPC 320 catheter. The DCE-MRI was carried out at a spatial resolution of 0.23 × 0.23 × 2.0 mm3 and a time resolution of 14 s by using a 1.5-T whole-body scanner and a slotted tube resonator transceiver coil constructed for mice. Parametric images were derived from the DCE-MRI recordings by using the Tofts iso-directional transport model and the Patlak uni-directional transport model. Results When gadomelitol was used as contrast agent, significant positive correlations were found between the parameters of both pharmacokinetic models and tumor IFP. On the other hand, significant correlations between DCE-MRI-derived parameters and IFP could not be detected with Gd-DTPA as contrast agent. Conclusion Gadomelitol is a superior contrast agent to Gd-DTPA in DCE-MRI of the IFP of CK-160 cervical carcinoma xenografts. Clinical studies attempting to develop DCE-MRI-based assays of the IFP of cervical carcinomas should involve contrast agents with higher MW than Gd-DTPA.

    Cervical carcinoma is the second most common malignancy of the female genital tract in India. The highest incidence occurs at Chennai. This study was conducted on 30 women with biopsy-proved squamous cell carcinoma of the cervix of stage IIb. The neutrophil count increased significantly in cancer patients compared to control subjects. Total protein, glycogen and total lipid increased in neutrophils of cervical cancer patients. The level of cholestrol, triglycerides and fatty acids increased significantly in neutrophils of such patients compared to control subjects. The activity of alkaline phosphatase increased significantly in cervical cancer patients. Upon treatment with cobalt-60, these changes were brought to near-normal levels. This study highlights the impairment in the neutrophil function in cervical cancer patients, which may lead to reduced immune status. (author)

    Accurate staging as well as diagnosis of cervix carcinoma is of paramount importance in planning treatment. Cervical smear cytologic studies have increased the detection rate of cervix carcinoma, but current radiologic techniques are limited in staging cervix carcinoma and precise visualization of lymphnodal metastasis. The CT scan can display the precise transaxial anatomical structures, permitting us not only to know the tumor size, shape and its extent but also lymphnodal enlargement in the pelvic cavity and around the abdominal aorta and secondary changes of the kidney. The authors have tested the usefulness of CT in staging cervix carcinoma and detecting lymphatic involvement by analysis of 24 cases diagnosed by CT and confirmed histologically at St. Mary's hospital during the period from October 1982 to May 1984. The conclusions are as follows: 1. The accuracy of CT in staging of cervix carcinoma was 79%. 2. The accuracy of CT diagnosis of lymphatic involvement was 87.5%, sensitivity was 85.7%, and specificity was 88.2%

    To assess cancers diagnosed and the stage of cancer at the time of diagnosis among low-income, under-insured, or uninsured women who received services through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Using the NBCCEDP database, we examined the number and percent of women diagnosed during 2009-2011 with in situ breast cancer, invasive breast cancer, and invasive cervical cancer by demographic and clinical characteristics, including age, race and ethnicity, test indication (screening or diagnostic), symptoms (for breast cancer), and screening history (for cervical cancer). We examined these characteristics by stage at diagnosis, a new variable included in the database obtained by linking with state-based central cancer registries. There were 11,569 women diagnosed with invasive breast cancer, 1,988 with in situ breast cancer, and 583 with invasive cervical cancer through the NBCCEDP. Women who reported breast symptoms or who had diagnostic mammography were more likely to be diagnosed with breast cancer, and at a later stage, than those who did not have symptoms or who had screening mammography. Women who had been rarely or never screened for cervical cancer were more likely to be diagnosed with cervical cancer, and at a later stage, than women who received regular screenings. Women served through the NBCCEDP who have not had prior screening or who have symptoms were more often diagnosed with late-stage disease.

    Cervical cancer is one of the most common malignant tumours of the female reproductive system, ranking second only to breast cancer in morbidity worldwide. Essential features of the progression of cervical cancer are invasion and metastasis, which are closely related to disease prognosis and mortality rate. At the present time there is no effective method to evaluate cancer invasion and metastasis before surgery. Here we report our study on molecular changes in biopsy tissue for the prognostic evaluation of cancer invasion and metastasis. Expression of the epithelial-mesenchymal transition-inducing transcription factors Twist1 and Snail1 was detected by immunohistochemistry in 32 normal, 36 low-grade squamous intraepithelial neoplasia (LSIL), 54 high-grade squamous intraepithelial neoplasia (HSIL) and 320 cervical squamous cell carcinoma (CSCC) samples. The correlation between the expression of Twist1, Snail1 and squamous cell carcinoma antigen (SCCA) in CSCC tissues and clinical pathology results was evaluated. A transwell migration and invasion assay was used to explore the roles of Twist1 and Snail1 in the invasion of cancer cells. Lymph node metastasis and lymphovascular space invasion (LVSI) rates for the following groups were analysed: SCCA(+) group, Twist1(+) group, Snail1(+) group, Twist1(+)Snail1(+)group, Twist1(+)SCCA(+)group, Snail1(+)SCCA(+)group and Twist1(+)Snail1(+)SCCA(+) group. The expression of Twist1 and Snail1 was significantly upregulated in HSIL and CSCC (p  0.05). The expression of SCCA was associated with LVSI, lymph node metastasis, FIGO stage and histological grade (p  0.05). Twist1 was an independent factor contributing to the invasion ability of cervical cancer cells. In addition, the positive rate of lymph node metastasis and LVSI was higher in the Twist1(+)Snail1(+)SCCA(+) group than in the SCCA(+) group, Twist1(+) group and Snail1(+) group, respectively (p < 0.05).

    To investigate the potential of various metrics derived from mono-exponential model (MEM), bi-exponential model (BEM) and stretched exponential model (SEM)-based diffusion-weighted imaging (DWI) in diagnosing and differentiating the pathological subtypes and grades of uterine cervical carcinoma. 71 newly diagnosed patients with cervical carcinoma (50 cases of squamous cell carcinoma [SCC] and 21 cases of adenocarcinoma [AC]) and 32 healthy volunteers received DWI with multiple b values. The apparent diffusion coefficient (ADC), pure molecular diffusion (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), water molecular diffusion heterogeneity index (alpha), and distributed diffusion coefficient (DDC) were calculated and compared between tumour and normal cervix, among different pathological subtypes and grades. All of the parameters were significantly lower in cervical carcinoma than normal cervical stroma except alpha. SCC showed lower ADC, D, f and DDC values and higher D* value than AC; D and DDC values of SCC and ADC and D values of AC were lower in the poorly differentiated group than those in the well-moderately differentiated group. Compared with MEM, diffusion parameters from BEM and SEM may offer additional information in cervical carcinoma diagnosis, predicting pathological tumour subtypes and grades, while f and D showed promising significance.

    Full Text Available We investigated the significance of high- mobility group box1 (HMGB1 and T-cell-mediated immunity and prognostic value in cervical cancer. HMGB1, forkhead/winged helix transcription factor p3 (Foxp3, IL-2, and IL-10 protein expression was analyzed in 100 cervical tissue samples including cervical cancer, cervical intraepithelial neoplasia (CIN, and healthy control samples using immunohistochemistry. Serum squamous cell carcinoma antigen (SCC-Ag was immunoradiometrically measured in 32 serum samples from 37 cases of squamous cervical cancer. HMGB1 and SCC-Ag were then correlated to clinicopathological characteristics. HMGB1 expression tends to increase as cervical cancer progresses and it was found to be significantly correlated to FIGO stage and lymph node metastasis. These findings suggest that HMGB1 may be a useful prognostic indicator of cervical carcinoma. In addition, there were significant positive relationships between HMGB1 and FOXP3 or IL-10 expression (both p < 0.05. In contrast, HMGB1 and IL-2 expression was negatively correlated (p < 0.05. HMGB1 expression may activate Tregs or facilitate Th2 polarization to promote immune evasion of cervical cancer. Elevated HMGB1 protein in cervical carcinoma samples was associated with a high recurrence of HPV infection in univariate analysis (p < 0.05. HMGB1 expression and levels of SCC-Ag were directly correlated in SCC (p < 0.05. Thus, HMGB1 may be a useful biomarker for patient prognosis and cervical cancer prediction and treatment.

    Full Text Available Nasopharyngeal carcinoma (NPC is a carcinoma that arises from the nasopharyngeal mucosa and differs from other head and neck carcinomas by its unique histologic, epidemiologic, and biologic characteristics. NPC is rare in most countries, especially Europe and North America. However, it has a high incidence in several regions of South China. The incidence variability of NPC, among different geographical and ethnic groups, indicates a combination of genetic susceptibility, infection by Epstein-Barr virus and environmental factors. NPC is classified into three histological subtypes according to the 1991 World Health Organization classification: squamous cell carcinoma, nonkeratinizing carcinoma, and basaloid squamous cell carcinoma. The symptoms of patients with NPC are related to the primary tumor site and the degree of dissemination. Therefore, patients can remain asymptomatic during a long period of time. Imaging exams and biopsy of the tumor mass generally are sufficient to establish the diagnosis. NPC is a rare disease among children. The authors report a case of a 12-year-old boy who sought medical attention complaining of a progressive growing tumoral mass on the right side of the neck. The computed tomography images of the head and neck and the histological examination of a cervical lymph node biopsy diagnosed a metastatic NPC.

    Full Text Available "nBackground: Treatment of cervical carcinoma is routinely performed with Low Dose Rate (LDR brachytherapy, but Brachytherapy in our department is done with Medium Dose Rate (MDR due to the technical characteristics of the machine available here. Thus we decided to evaluate the results of this treatment in our department in a prospective study. "nMethods: Between March 2006 and July 2008, 140 patients with histologic diagnosis of cervical carcinoma referred to Tehran Cancer Institute; were treated with external beam radiotherapy (44-64 Gy to whole pelvis and MDR brachytherapy (8-30 Gy to Point A with a dose rate of 2.2±0.3 Gy/h. "nResults: 121 patients were followed up for a median time of 18 months (range: 9-39 m. There were 11%(6/54 local recurrence for surgery and adjuvant radiotherapy group; 25%(16/65 for radical radiotherapy group, and 19%(23/121 for all patients. Rectal and bladder complications incidence for all patients were 10%(12/121 and 13%(16/121 respectively. High grade complication was shown only in one patient in radical radiotherapy group. In this study 3-years disease free survival and overall survival were 73% and 92% respectively, and disease stage (p=0.007 and overall treatment time (p=0.05 were the significant factors affecting disease free survival. "nConclusions: Results of this series suggest that the use of external beam radiotherapy and MDR brachytherapy with about 20% dose reduction in comparison with LDR can be an acceptable technique with regard to local control and complications.

    Squamous cell oesophageal carcinoma is the most common carcinoma of the oesophagus worldwide. The tumour stage as most important prognostic factor determines the clinical management. Aim of this study was to evaluate the value of FDG-PET 1. in imaging the primary tumour and 2. in N- and M-staging of squamous cell oesophogeal carcinoma. Patients, methods: in 20 patients with histological proven squamous cell carcinoma of the upper and middle oesophagus, FDG-PET was performed in standard technique prior to therapy. FDG uptake in the primary was determined by calculation of the SUVmax. NM-staging due to PET findings was performed as designated by the AJCC/UICC group classification and was compared with pathological and clinically based staging. Sensitivities, specificities and accuracies were calculated. Results: in 19 of 20 patients, primary squamous cell oesopohageal carcinoma was detected by FDG-PET findings with a maximum SUV of 12.5 (mean) ± 5.1 (median 11.5; range 4.8-23.8). One carcinoma in situ was missed. The sensitivity of FDG-PET in imaging the primary tumour was 96%. The sensitivities, specificities and accuracies were 20%, 100%, 58% for N-staging, and 60%, 86% and 93% for M-staging. PET findings caused changes of therapy in 5% (1 patient). Conclusions: FDG-PET was excellent in imaging the primary of squamous cell oesophageal carcinoma in stage T1-T4 and was efficient in M-staging. The low sensitivity in N-staging is of inferior clinical importance. The efficacy of FDG-PET seems to be not significantly be influenced by the histological subtype of oesophageal carcinoma. (orig.)

    In vivo dosimetry in bladder and rectum as well as determining doses on suggested reference points following the ICRU report 38 contribute to quality assurance in HDR-brachytherapy of cervical carcinoma, especially to minimize side effects. In order to gain information regarding the radiation exposure at ICRU reference points in rectum, bladder, ureter and regional lymph nodes those were calculated (digitalisation) by means of orthogonal radiographs of 11 applications in patients with cervical carcinoma, who received primary radiotherapy. In addition, the doses at the ICRU rectum reference point was compared to the results of in vivo measurements in the rectum. The in vivo measurements were by factor 1.5 below the doses determined for the ICRU rectum reference point (4.05 +/- 0.68 Gy versus 6.11 +/- 1.63 Gy). Reasons for this were: calibration errors, non-orthogonal radiographs, movement of applicator and probe in the time span between X-ray and application, missing connection of probe and anterior rectal wall. The standard deviation of calculations at ICRU reference points was on average +/- 30%. Possible reasons for the relatively large standard deviation were difficulties in defining the points, identifying them on radiographs and the different locations of the applicators. Although 3 D CT, US or MR based treatment planning using dose volume histogram analysis is more and more established, this simple procedure of marking and digitising the ICRU reference points lengthened treatment planning only by 5 to 10 minutes. The advantages of in vivo dosimetry are easy practicability and the possibility to determine rectum doses during radiation. The advantages of computer-aided planning at ICRU reference points are that calculations are available before radiation and that they can still be taken into account for treatment planning. Both methods should be applied in HDR-brachytherapy of cervical carcinoma.

    Staging of carcinoma of the urinary bladder is important for the choice of therapy and also has prognostic implications. Hitherto the staging has been based upon cystoscopy with biopsy, transurethral resection, and palpation with complementary radiographic examinations such as cystography, urography, lymphangiography, ultrasound and angiography. However, with all these methods, the staging of bladder carcinomas still uncertain and inferior to CT. Authors analyzed CT staging of bladder cancers and compared with pathologic staging of laparotomy results. The results are as following: 1. Overall accuracy of CT staging in bladder carcinoma was 72 percent. 2. Overstaging was 20 percent (5/25) and understaging was 8 percent (2/25). 3. All of CT stage B cancers were proven to be stage B, pathologically. 4. In 6 cases of CT static cancers, only one was correct, 3 were overstaged and 2 were understaged. 5. In 7 cases of CT stage D cancers, 5 were correct and 2 were overstaged. 6. CT detected only 2 cases of pelvic lymph node involvement in 4 of pathologically proven lymphadenopathy

    We conducted this study to evaluate the efficacy and safety of adjuvant chemotherapy using taxane plus carboplatin (CBDCA) for high-risk stage IB-IIB patients with uterine cervical non-squamous cell carcinoma after radical hysterectomy. Thirty-seven patients were eligible. Pelvic lymph node involvement and/or parametrial invasion were defined as high-risk factors. The patients were treated with 6 cycles of paclitaxel (PTX, 175 mg/m(2)) or docetaxel (DTX, 60 mg/m(2)) followed by CBDCA (area under the curve, 6) every 3 weeks. The primary end point was 2-year progression-free survival (PFS) rate, and the secondary end point was the assessment of adverse events. Twenty-two patients received PTX/CBDCA (TC) chemotherapy, and the remaining 15 patients underwent DTX/CBDCA (DC) chemotherapy. The 2-year PFS rate was 62.1% (95% confidence interval, 44.6%-75.5%). Patients receiving DC chemotherapy showed a better 2-year PFS rate compared to those with TC chemotherapy, but the difference was not statistically significant (80.0% vs 50.0%, P = 0.1400). The most common grade 3/4 adverse events were hematologic toxicities, which were generally well tolerable. Nonhematologic toxicity was generally mild. Taxane and CBDCA combination chemotherapy, especially DC chemotherapy, may be one of the useful adjuvant treatments for high-risk stage IB-IIB patients with uterine cervical non-squamous cell carcinoma after radical hysterectomy.

    Background and Purpose: To date, no information is available concerning the impact of spinal anesthesia on the oxygenation status of carcinomas of the uterine cervix. The aim of this study was therefore to determine the influence of spinal anesthesia on the oxygenation status of cervical carcinomas. Patients and Methods: In ten patients with cervical carcinoma who received spinal anesthesia for a first application of brachytherapy, intratumoral pO 2 measurements (pO 2 histography system, Eppendorf-Netheler-Hinz, Hamburg, Germany) were performed. Systemic parameters were documented prior to and during spinal anesthesia. Patients breathed room air spontaneously. For further evaluation, all intratumoral pO 2 values were pooled, and overall median pO 2 values and fractions of hypoxic pO 2 values ≤ 5 mm Hg were calculated. Overall median pO 2 values in the subcutis were also calculated. Results: There were no significant changes of systemic parameters, median subcutaneous pO 2 values, median intratumoral pO 2 values, and the fractions of hypoxic pO 2 values ≤ 5 mm Hg in the tumor upon administration of spinal anesthesia. The variability of measured pO 2 values increased during spinal anesthesia, although substantial changes in the oxygenation status were only seen in individual cases (n = 2). Conclusion: This study shows for the first time that the oxygenation status of cervical carcinomas, in general, is not influenced by spinal anesthesia prior to application of brachytherapy. To conclude, the data presented suggest that reliable pO 2 measurements can be performed under spinal anesthesia. At the same time, since no substantial changes in tumor oxygenation were observed, spinal anesthesia should not affect the O 2 -related efficacy of high-dose-rate brachytherapy. (orig.)

    Full Text Available Fibroblast growth factor receptor 3 (FGFR3 seems to play an inhibitory role in bone development, as activating mutations in the gene underlie disorders such as achondroplasia and thanatophoric dysplasia. Findings from multiple myeloma (MM indicate that FGFR3 also can act as an oncogene, and mutation of codon 249 in the fibroblast growth factor receptor 3 (FGFR3 gene was recently detected in 3/12 primary cervical carcinomas. We have analysed 91 cervical carcinomas for this specific S249C mutation using amplification created restriction site methodology (ACRS, and detected no mutations. Immunohistochemistry was performed on 73 of the tumours. Reduced protein staining was seen in 43 (58.8% samples. Six of the tumours (8.2% revealed increased protein staining compared with normal cervical tissue. These patients had a better prognosis than those with reduced or normal levels, although not statistically significant. This report weakens the hypothesis of FGFR3 as an oncogene of importance in cervical carcinomas.

    To investigate patterns of failure and survival rates of elective irradiation of upper neck in N0 nasopharyngeal carcinoma patients. From February 1996 to November 2002, 97 patients without cervical lymph node involvement were admitted for radiotherapy alone. Before treatment, each patient underwent enhanced CT of nasopharynx and neck. All patients received radiotherapy to the nasopharynx, skull base, and upper neck drainage areas (including levels II, III, and VA). The upper neck was irradiated to a total dose of 50-56 Gy/25-28 fractions/5-5.6 weeks. For the primary tumor, 22 patients used conventional fractionation for a total dose of 70 Gy/35 fractions/7 weeks, and 75 patients used an accelerated hyperfractionationated schedule for a total dose of 78 Gy/60 fractions/6 weeks. The median follow-up of these 97 patients was 7.75 years. 10 patients had recurrences in the nasopharynx, 8 had distant metastasis, and 5 had recurrences in the cervical lymph nodes. Among the cervical lymph node failures, the areas of recurrence were in the II drainage areas in 4 patients who had neck dissections afterwards, and in IA drainage areas in 1 patient who also had recurrence in the nasopharynx. The causes of death were recurrence in the nasopharynx for 8 patients, 1 of these also had recurrence in the neck, distant metastases in 8 patients, and non-neoplastic diseases in 3 patients. The causes of failure of N0 patients with nasopharyngeal carcinoma after radiotherapy alone to the nasopharynx and upper neck were nasopharyngeal recurrence, distant metastasis, and cervical recurrence in order of frequency. Elective irradiation of upper neck (II, III, VA) is advised for stage N0 patients diagnosed by enhanced CT of neck. Cervical recurrence alone is rare, which did not greatly affect the long-term survival after salvage neck dissection

    Full Text Available Background: The aim of the present study was to compare the cervical vertebra maturation stages method and dental maturity using tooth calcification stages. Methods: The current study comprised of 405 subjects selected from orthodontic patients of Saudi origin coming to clinics of the specialized dental centers in western region of Saudi Arabia. Dental age was assessed according to the developmental stages of upper and lower third molars and skeletal maturation according to the cervical vertebrae maturation stage method. Statistical analysis was done using Kruskal-Wallis H, Mann-Whitney U test, Chi-Square test; t-test and Spearman correlation coefficient for inter group comparison. Results: The females were younger than males in all cervical stages. The CS1-CS2 show the period before the peak of growth, during CS3-CS5 it’s the pubertal growth spurt and CS6 is the period after the peak of the growth. The mean age and standard deviation for cervical stages of CS2, CS3 and CS4 were 12.09 ±1.72 years, 13.19 ±1.62 and 14.88 ±1.52 respectively. The Spearman correlation coefficients between cervical vertebrae and dental maturation were between 0.166 and 0.612, 0.243 and 0.832 for both sexes for upper and lower third molars. The significance levels for all coefficients were equal at 0.01 and 0.05. Conclusion: The results of this study showed that the skeletal maturity increased with the increase in dental ages for both genders. An early rate of skeletal maturation stage was observed in females. This study needs further analysis using a larger sample covering the entire dentition.

    Computed Tomography (CT) was found to be highly accurate in predicting tumor size and assessing invasion of the surrounding structures and distant metastasis. Also CT played an important role for determination of operability of esophageal carcinoma. The CT findings with barium esophagogram in 21 patients with histologically proven esophageal carcinoma were reviewed from Feb. 1985 to Feb. 1986 at the department of Radiology, Yonsei University, College of Medicine. The results were as follows: 1. Number of patients in each stages were: 2 in stage 1, 6 in stage 2, 4 in stage 3, and 9 in stage 4. 2. Paek age distribution was in tis 6th decades as 9 patients (42.9%). Overall mean age was 60.8 years. Number of male patients were 19 and 2 of female. 3. Histologic types of esophageal carcinoma were 19 cases of epidermoid (90.5%) and 2 cases of adenocarcinoma (9.5%). 4. The tumor location was 1 case in upper, 14 cases (66.7%) in middle and 6 cases in lower one-third. 5. Various types of esophageal carcinoma were as follows: 3 cases of fungating, 4 cases of infiltrating, 5 cases of ulcerofungating, and 9 cases of ulceroinfiltrating type. 6. Average length of involvement in each stages were 4 cm in stage 1, 5.5 cm in stage 2, 8.8 cm stage 3, and 8.3 cm in stage 4. The involved length was longer in advanced cases. In 11 cases (52.4%), the involved length was between 4 and 8 cm. 7. Angle of periaortic fat plane obliteration of the aortic circumference were as follows: Below 45 (7 cases 33.3%), 45-90 (3 cases 14.3%), over 90 (11 cases, 52.4%). 8. Method of treatment of esophageal carcinoma were as follows: Only radiotherapy in 11 cases (52.4%), radiotherapy with operation in 5 cases, only operation on 1 case, and no treatment in 4 cases. 9. Distant metastatic sites were: brain in 1, pericardium in 5, liver in 5, trachea in 2, bronchus in 9, and distant lymph node in 5 cases.

    Objective: To evaluate the therapeutic effect of intra-arterial chemotherapy with Ddp and 5-Fu via bilateral uterine arteries for advanced uterine cervical cancer. Methods: During the period of Jan. 2006-Jan. 2009, initial intra-arterial chemotherapy by using a combination of Ddp and 5-Fu via bilateral uterine arteries was performed in 72 patients (mean age 42.9 years) with advanced uterine cervical caner. Of 72 patients, stage I b2 cervical cancer was confirmed in 28, stage II a in 12 and stage II b in 32. Pathologically, cervical squamous cell carcinoma was seen in 56 and cervical adenocarcinoma in 16 patients. Ultrasonography and physical examination were conducted both before and after intra-arterial chemotherapy. The therapeutic results,complications,the surgical resection rate and the pathologic findings were observed and statistically analyzed. Results: Fifty-four patients received one treatment course and 18 patients received two treatment courses. The over all response rate was 77.8%. The response rates of patients with I b2, II a and II b cervical cancer were 92.9%, 83.3% and 62.5% respectively, the difference between three groups was statistically significant (P < 0.05). And the response rates of patients with squamous cell carcinoma and adenocarcinoma were 85.7% and 50.0% respectively, the difference between the two was statistically significant (P < 0.05). The most common side-effects included gastrointestinal symptoms and bone marrow suppression. Thirty-four patients received radical hysterectomy,among them, 22 (78.6%) had stage I b2, 8 (66.7%) had stage II a and 4 (12.5%) had stage II b cervical cancer (P < 0.05). Pathologic exam found no vaginal invasion and ovarian metastasis in all 34 patients. The occurrence of metastasis to lymph nodes and para uterine infiltration were 17.6% and 11.8% respectively. Conclusion: Intra-arterial chemotherapy with a combination of DDP and 5-Fu via bilateral uterine arteries can safely and effectively reduce the

    A close relationship exists between immune response and tumor behavior. This study aimed to explore the associations between radiation-induced apoptosis (RIA) in peripheral blood lymphocytes (PBL) and clinical pathological variables. Furthermore, it assessed the role of RIA as a prognostic factor for survival in cervical carcinoma patients. Between February 1998 and October 2003, 58 consecutive patients with nonmetastatic, localized stage I-II cervical carcinoma who had been treated with radiotherapy (RT) ± chemotherapy were included in this study. Follow-up ended in January 2013. PBL subpopulations were isolated and irradiated with 0, 1, 2 and 8 Gy then incubated for 24, 48 and 72 h. Apoptosis was measured by flow cytometry and the ss value, a parameter defining RIA of lymphocytes, was calculated. Mean follow-up duration was 111.92 ± 40.31 months. Patients with lower CD8 T lymphocyte ss values were at a higher risk of local relapse: Exp(B) = 5.137, confidence interval (CI) 95 % = 1.044-25.268, p = 0.044. Similar results were observed for regional relapse: Exp(B) = 8.008, CI 95 % = 1.702-37.679, p = 0.008 and disease relapse: Exp(B) = 6.766, CI 95 % = 1.889-24.238, p = 0.003. In multivariate analysis, only the CD8 T lymphocyte ss values were found to be of prognostic significance for local disease-free survival (LDFS, p = 0.049), regional disease-free survival (RDFS, p = 0.002), metastasis-free survival (MFS, p = 0.042), disease-free survival (DFS, p = 0.001) and cause-specific survival (CSS p = 0.028). For the first time, RIA in CD8 T lymphocytes was demonstrated to be a predictive factor for survival in cervical carcinoma patients. (orig.)

    The skeletal maturation status of a growing patient can influence the selection of orthodontic treatment procedures. Either lateral cephalometric or hand-wrist radiography can be used to assess skeletal development. In this study, we examined the correlation between the maturation stages of cervical vertebrae and hand-wrist bones in Taiwanese individuals. The study group consisted of 330 male and 379 female subjects ranging in age from 8 to 18 years. A total of 709 hand-wrist and 709 lateral cephalometric radiographs were analyzed. Hand-wrist maturation stages were assessed using National Taiwan University Hospital Skeletal Maturation Index (NTUH-SMI). Cervical vertebral maturation stages were determined by the latest Cervical Vertebral Maturation Stage (CVMS) Index. Spearman's rank correlation was used to correlate the respective maturation stages assessed from the hand-wrist bones and the cervical vertebrae. The values of Spearman's rank correlation were 0.910 for males and 0.937 for females, respectively. These data confirmed a strong and significant correlation between CVMS and NTUH-SMI systems (p less than 0.001). After comparison of the mean ages of subjects in different stages of CVMS and NTU-SMI systems, we found that CVMS I corresponded to NTUH-SMI stages 1 and 2, CVMS II to NTUH-SMI stage 3, CVMS III to NTUHSMI stage 4, CVMS IV to NTUH-SMI stage 5, CVMS V to NTUH-SMI stages 6, 7 and 8, and CVMS VI to NTUH-SMI stage 9. Our results indicate that cervical vertebral maturation stages can be used to replace hand-wrist bone maturation stages for evaluation of skeletal maturity in Taiwanese individuals.

    Full Text Available Background Persistent infection of high risk genotypes of human papilloma virus (hrHPV has been established as the etiological cause for cervical cancer, and the most prevalent genotypes that infect the cervical tissue are HPV-16 and HPV-18. However, HPV genotype profile has been shown to differ according to geographical distribution across the globe. The present study aimed to determine the HPV genotype distribution in cervical cancer patients from Bandung, Indonesia. Methods During the period of July – November 2010 viral DNA was extracted from randomly chosen cervical cancer biopsies and subjected to genotype determination using the diagnostic linear array genotyping test (Roche. The distribution of HPV genotypes was explored and the prevalence of HPV genotypes was mapped. Results Of 96 cervical cancer tissue samples, 76 (79.2% were histopathologically classified as squamous cell cervical carcinoma. Due to the high cost of HPV genotyping tests, only twenty-five samples were randomly genotyped. Almost 90% of the cervical cancer patients were multiply infected with HPV-16 in combination with HPV-18, HPV-45, or HPV-52. The HPV-16 genotype had the highest prevalence, all samples being infected with HPV-16. Conclusion The cervical cancer cases were predominantly infected by multiple hrHPVs with HPV-16 as the major genotype among other hrHPVs, supporting the carcinogenic role of this hrHPV. Therefore, screening for hrHPVs in the general population is urgently needed as a means of early detection of cervical cancer.

    Full Text Available Abstract Background High risk type human papilloma viruses (HR-HPV induce carcinomas of the uterine cervix by expressing viral oncogenes E6 and E7. Oncogene E7 of HR-HPV disrupts the pRb/E2F interaction, which negatively regulates the S phase entry. Expression of tumor suppressor p16ink4a drastically increases in majority of HR-HPV associated carcinomas due to removal of pRb repression. The p16ink4a overexpression is an indicator of an aberrant expression of viral oncogenes and may serve as a marker for early diagnostic of cervical cancer. On the other hand, in 25–57% of cervical carcinomas hypermethylation of the p16 INK4a promoter has been demonstrated using a methylation-specific PCR, MSP. To evaluate a potential usage of the p16 INK4a 5' CpG island hypermethylation as an indicator of tumor cell along with p16ink4a overexpression, we analyzed the methylation status of p16 INK4a in cervical carcinomas Methods Methylation status of p16 INK4a was analyzed by MSP and by bisulfite-modified DNA sequencing. The expression of p16ink4a was analyzed by RT-PCR and by immunohistochemical technique. Results The extensive methylation within p16 INK4a 5' CpG island was not detected either in 13 primary cervical carcinomas or in 5 cancer cell lines by bisulfite-modified DNA sequencing (including those that were positive by MSP in our hands. The number and distribution of rare partially methylated CpG sites did not differ considerably in tumors and adjacent normal tissues. The levels of the p16 INK4a mRNA were increased in carcinomas compared to the normal tissues independently of the number of partially methylated CpGs within 5'CpG island. The transcriptional activation of p16 INK4a was accompanied by p16ink4a cytoplasmic immunoreactivity in the majority of tumor cells and presence of a varied number of the p16 positive nuclei in different tumors. Conclusion Hypermethylaion of the p16INK4a 5' CpG island is not a frequent event in HR-HPV-positive cervical

    This paper describes the present state of radiotherapy (RT) of early stage cervical cancer involving the history, outcomes of clinical trials, procedure for each stage, irradiation methods, concurrent chemo-RT (CCRT), late adverse events, and QOL after RT. It has a history of >100 years from the brachytherapy with radium, but is not yet completely established even now. There are many RT trials hitherto. Retrospectively, no significant difference is seen in outcomes of radical RT and surgery: 80-90% efficacy for stage I and 60-80% for II in the former, respectively, and 80-96% and 65-80%, in the latter. Between RT and surgery, there is a report of randomized comparative study in Italy. In Japan, reported are comparative outcomes based on patients' choice for therapy, retrospective studies including authors' one, prospective multi-institutional cooperative trials by Japanese Radiation Oncology Study Group, and Treatment Guidelines for Cervical Cancer (2007). RT procedure depends on the stage defined by FIGO (International Federation of Gynecology and Obstetrics) and at stages I-II, intracavitary RT is major with optimal dose 29 Gy/5 fractions for I, and 23/4 Gy with external total pelvic radiation 50 Gy for II. In external radiation, the planning target volume includes the whole pelvic field with 1.8-2 Gy/5 weeks and optionally, the extended field when metastasis suspicious. Intracavitary RT with application device in the uterine is of significance for the cancer as 50% complete cure even in stage III is reported. CCRT brings about good prognosis, which is shown in a Japanese trial to compare postoperative RT alone and CCRT with CDDP and 5-FU. The late adverse events are seen mainly in the large bowel and studies of QOL, an important factor for choice of treatment, are now in progress. (T.T.)

  7. Cervical Microbiome and Cytokine Profile at Various Stages of Cervical Cancer: A Pilot Study.

    Directory of Open Access Journals (Sweden)

    Astride Audirac-Chalifour

    Full Text Available Cervical cancer (CC is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST. Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL and CC(p = 0.006, p = 0.036.When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006 and the largest distance compared to NCL-HPV negative ones (p<0.00001. The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings.

    BACKGROUND: Small cell carcinoma of the cervix is a rare cancer, comprising less than 3% of all cervical neoplasms. It uniformly has a poor prognosis, and has a high mortality even with early stage disease. It can metastasise rapidly and metastatic sites include lung, liver, brain, bone, pancreas and lymph nodes. CASE: Here, we report the case of a 60-year-old woman with no symptoms of cervical pathology who developed post-renal failure following a laparoscopic cholecystectomy. The cause was bilateral ureteric obstruction from metastatic small cell cervical cancer and metastases were subsequently found on her gallbladder specimen. CONCLUSION: This is an unusual presentation of small cell cervical cancer and demonstrates the aggressive nature of this disease.

    1999-01-01

    Forty-four patients of nasopharyngeal carcinoma, treated in Tsukuba University Hospital between March 1988 and March 1998, were reviewed in order to assess the adequacy of our treatment protocol. Most of the cases except 5 were histologically diagnosed as squamous cell carcinoma including 25 of lymphoepithelioma (poorly-differentiated squamous cell carcinoma). Thirty-two out of 39 squamous cell carcinoma cases have fallen into Stage IV category (UICC, 1987) , and all of the non-squamous cell carcinoma cases were also categorized as Stage IV. The basic protocol for nasopharyngeal squamous cell carcinoma was the combination of full-dose irradiation and chemotherapy using cisplatin/carboplatin and peplomycin. The metastatic cervical lymphnodes in 9 cases, too massive to control by this treatment, were surgically dissected after the treatment. Recurrence was noted in 9 cases who were rehospitalized and salvaged medically and/or surgically. As a consequence, the overall 5-year survival rate was 71.4% for squamous cell carcinoma. On the other hand, only one of the 5 non-squamous cell carcinoma cases died of the disease. (author)

    Full Text Available OBJECTIVE: To determine the relative contribution of known high-risk human papillomavirus (HPV genotypes to the occurrence of cervical cancers in Trinidad. METHODS: The distribution of HPV genotypes in cases of invasive cervical squamous cell carcinoma in Trinidad was investigated. This study was a follow-up to an investigation of HPV genotypes in 310 nonsymptomatic women in Trinidad. The latter study showed that cervical HPV prevalence and heterogeneity of genotypes were high in the study population; notably, the genotypes targeted by the available HPV prophylactic vaccines were not the most common types. RESULTS: The current study of 85 cases of invasive cervical squamous cell carcinomas demonstrated that the previously observed heterogeneity in HPV genotype distribution is lost in cases of invasive cervical cancer, with the vaccine-targeted HPV types HPV 16 and HPV 18 becoming the most prevalent. CONCLUSIONS: HPV 16 and HPV 18 were the primary HPV genotypes associated with cases of invasive squamous cell carcinoma in the current Trinidad study. This strong association leads us to conclude that the HPV vaccines targeting HPV 16 and HPV 18 may contribute to reducing the cervical cancer burden in Trinidad.OBJETIVO: Determinar la contribución relativa de los diferentes genotipos de virus de los papilomas humanos (VPH conocidos como de alto riesgo para la aparición de cáncer cervicouterino en Trinidad. MÉTODOS: Se investigó la distribución de los genotipos de VPH en casos de carcinoma cervicouterino escamocelular invasor en Trinidad. Este estudio fue la continuación de una investigación de los genotipos de VPH presentes en 310 mujeres asintomáticas en Trinidad. Este último estudio reveló altas prevalencia de VPH en el cuello uterino y heterogeneidad de los genotipos en la población del estudio; cabe destacar que los genotipos a los que se dirigen las vacunas preventivas de la infección por VPH disponibles no fueron los tipos m

    Full Text Available Aims and Objective: Over 70% of the cases present in advanced stages of the disease and are associated with poor prognosis and high mortality rates. In many of them, it is difficult to offer definitive treatment as they present in uremia due to associated obstructive uropathy. There are no clear-cut guidelines for performing percutaneous nephrostomy (PCN in patients of advanced cervical cancer. The results are unpredictable in terms of benefits achieved in these cases. Thus, we evaluated our experiences with PCN in the management of cervical cancer patients presenting with obstructive uropathy. Material and Methods: 15 patients of cervical cancer with obstructive uropathy and deranged renal functions were retrospectively evaluated for the role of PCN in their management Results: PCN was done in 15 patients of advanced cervical cancer. The mean age of patients was 44.5 years. Twelve (80% patients presented primarily with advanced cervical carcinoma and obstructive uropathy. Three (20% were already treated. Symptomatic improvement and significant fall of mean serum creatinine value from 7.5 mg% to 0.9 mg% over a period of 1-3 weeks was noted post PCN. Out of 12 patient with primary untreated advanced disease, curative treatment was possible in 3, palliative radiotherapy/chemo-therapy in 7 and only symptomatic treatment in 2 cases, after obstructive uropathy was managed with PCN insertion. Out of 3 already treated patients, 2 were disease free after curative radiotherapy/surgery. PCN was done to prevent permanent kidney damage in them. One patient was defaulter of curative radiotherapy. She had progressive residual disease. Complications like hemorrhage (20%, infection (26%, reinsertion for dislodgment/misplacement (53%, percutaneous leak or perinephric leak (20%, blockage of PCN (33% were noticed. Conclusion: In spite of inherent, albeit manageable complications, PCN is a simple and safe technique. One of the major benefits observed was

    In squamous cell carcinoma, squamous cell carcinoma antigen levels are often elevated. This multi-center study evaluated the technical performance of a new Elecsys ® squamous cell carcinoma assay, which measures serum squamous cell carcinoma antigen 1 and 2 levels in an equimolar manner, and investigated the potential of squamous cell carcinoma antigen for differential diagnosis of cervical, lung, and head and neck squamous cell carcinoma.Assay precision and method comparison experiments were performed across three European sites. Reference ranges for reportedly healthy individuals were determined using samples from banked European and Chinese populations. Differential diagnosis experiments determined whether cervical, lung, or head and neck cancer could be differentiated from apparently healthy, benign, or other malignant cohorts using squamous cell carcinoma antigen levels alone. Squamous cell carcinoma antigen cut-off levels were calculated based on squamous cell carcinoma antigen levels at 95% specificity. Repeatability coefficients of variation across nine analyte concentrations were ≤5.3%, and intermediate precision coefficients of variation were ≤10.3%. Method comparisons showed good correlations with Architect and Kryptor systems (slopes of 1.1 and 1.5, respectively). Reference ranges for 95th percentiles for apparently healthy individuals were 2.3 ng/mL (95% confidence interval: 1.9-3.8; European cohort, n = 153) and 2.7 ng/mL (95% confidence interval: 2.2-3.3; Chinese cohort, n = 146). Strongest differential diagnosis results were observed for cervical squamous cell carcinoma: receiver operating characteristic analysis showed that squamous cell carcinoma antigen levels (2.9 ng/mL cut-off) differentiate cervical squamous cell carcinoma (n = 127) from apparently healthy females (n = 286; area under the curve: 86.2%; 95% confidence interval: 81.8-90.6; sensitivity: 61.4%; specificity: 95.6%), benign diseases (n = 187; area

    Merkel cell carcinoma is a rare lymphophilic skin tumor of neuroendocrine origin with the potential for rapid progression. Small, localized lesions are diagnosed and treated clinically, but advanced tumors often undergo imaging evaluation. Due to its rarity, radiologists are unaware of evocative imaging features and usually do not consider Merkel cell carcinoma in the differential diagnosis of soft tissue tumors. Appropriate staging is important to determine appropriate treatment and has an impact on patient prognosis. Multimodality imaging is usually needed, and there is no consensus on the optimal imaging strategy. The purpose of this article is to review various aspects of Merkel cell carcinoma imaging and look in detail at how optimal multimodality staging should be carried out. (orig.)

    High risk type human papilloma viruses (HR-HPV) induce carcinomas of the uterine cervix by expressing viral oncogenes E6 and E7. Oncogene E7 of HR-HPV disrupts the pRb/E2F interaction, which negatively regulates the S phase entry. Expression of tumor suppressor p16 ink4a drastically increases in majority of HR-HPV associated carcinomas due to removal of pRb repression. The p16 ink4a overexpression is an indicator of an aberrant expression of viral oncogenes and may serve as a marker for early diagnostic of cervical cancer. On the other hand, in 25–57% of cervical carcinomas hypermethylation of the p16 INK4a promoter has been demonstrated using a methylation-specific PCR, MSP. To evaluate a potential usage of the p16 INK4a 5' CpG island hypermethylation as an indicator of tumor cell along with p16 ink4a overexpression, we analyzed the methylation status of p16 INK4a in cervical carcinomas Methylation status of p16 INK4a was analyzed by MSP and by bisulfite-modified DNA sequencing. The expression of p16 ink4a was analyzed by RT-PCR and by immunohistochemical technique. The extensive methylation within p16 INK4a 5' CpG island was not detected either in 13 primary cervical carcinomas or in 5 cancer cell lines by bisulfite-modified DNA sequencing (including those that were positive by MSP in our hands). The number and distribution of rare partially methylated CpG sites did not differ considerably in tumors and adjacent normal tissues. The levels of the p16 INK4a mRNA were increased in carcinomas compared to the normal tissues independently of the number of partially methylated CpGs within 5'CpG island. The transcriptional activation of p16 INK4a was accompanied by p16 ink4a cytoplasmic immunoreactivity in the majority of tumor cells and presence of a varied number of the p16 positive nuclei in different tumors. Hypermethylaion of the p16INK4a 5' CpG island is not a frequent event in HR-HPV-positive cervical carcinomas and cannot be an effective

    Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed. A 36-year-old man presented with a solitary cystic cervical swelling, initially diagnosed as branchial cleft cyst. Fine needle aspiration yielded 18 ml of straw-coloured fluid. During cytological examination no atypical cells were observed. Computed tomography of the neck showed a heterogeneous mass with multiseptation medial to the sternocleidomastoid muscle. Histopathological examination of the mass, post excision, revealed a metastatic lymph node. A suspicious mucosal lesion at the nasopharynx was detected after repeated thorough head and neck examinations and the biopsy result confirmed undifferentiated nasopharyngeal carcinoma. Cystic cervical metastasis may occur in young patients under 40 years. The primary tumour may not be obvious during initial presentation because it mimicks benign branchial cleft cyst clinically. Retrospective review of the computed tomography images revealed features that were not characteristic of simple branchial cleft cyst. The inadequacy of assessment and interpretation had lead to the error in diagnosis and subsequent management. Metastatic head and neck lesion must be considered in a young adult with a cystic neck mass.

    Lymphoepithelioma-like carcinoma occurring in the reproductive organs is a rare variant of squamous cell carcinoma, and this tumor of the uterine cervix accounts for 0.7% of all primary cervical uterine neoplasms. Associations with Epstein-Barr virus (EBV) and human papilloma virus (HPV) have been demonstrated in some studies. Some investigators suggested that EBV has an important role in the initiation of lymphoepitheliomalike carcinoma in Asian women. Here we report the case of a 45-year-old Japanese woman, gravida 2 and parity 2. She was admitted due to severe atypical genital bleeding caused by uterine cervical cancer. A >60-mm tumor was detected at the uterine cervix, and no distal metastasis or swallowing of lymph nodes was revealed by magnetic resonance imaging and a computed tomography scan. The cervical cancer stage FIGO Ib2 was diagnosed, and a radical hysterectomy was performed for this malignant tumor. The in situ hybridization for EBV was negative. HVP infection was strongly suspected because the squamous cell carcinoma was observed macroscopically in the uterine cervix. The prognosis of uterine lymphoepithelioma-like carcinoma is thought to be better than those of other cervical cancer types, but careful follow-up at fixed intervals is recommended. The patient has been followed up for 4 months since her surgery, and no evidence of recurrence has been detected.

    The purpose was to investigate the potential value of apparent diffusion coefficient (ADC) measurement with MRI in the assessment of cervix cancer. Diffusion-weighted MRI was performed in 47 patients with cervical carcinoma undergoing chemoradiation therapy and 26 normal controls on a 1.5-T system with a b-value of 600 s/mm 2 . FIGO stage, tumor volume, nodal status, interstitial fluid pressure (IFP) and oxygen measurements were recorded. Response was defined as no visible tumor 3-6 months following completion of therapy. The average median ADC (mADC) of cervical carcinomas (1.09±0.20 x 10 -3 mm 2 /s) was significantly lower than normal cervix (2.09±0.46 x 10 -3 mm 2 /s) (P -3 mm 2 /s) compared to T2b (1.21 x 10 -3 mm 2 /s) and T3/T4 (1.10 x 10 -3 mm 2 /s) (P<0.001). In patients with squamous carcinomas the 90th percentile of ADC values was lower in responders than non-responders (P<0.05). Median ADC in cervix carcinoma is significantly lower compared to normal cervix. ADC may have predictive value in squamous tumors, but further long-term study will determine the ultimate clinical utility. (orig.)

    Objective: To evaluate the CT manifestations of cephalic and cervical adenoid cystic carcinoma (ACC). Methods: Thirty-three cases of ACC were analyzed retrospectively. Of all cases, 22 cases underwent operation and 11 cases received radiotherapy. The manifestations of CT were evaluated and compared with the clinical and pathologic results. Results: Tumors originated from parotid gland (5 cases), floor of mouth (5 cases), nasal cavity and nasopharynx (5 cases), tongue (4 cases), palate (3 cases), tracheas (3 cases), submandibular gland (2 cases), tonsilla (2 cases), maxillary sinus (2 cases), and cheek (2 cases), respectively. The CT manifestations included: (1)ethmoid density in 21 cases, partial ethmoid density in 5 cases. (2)the morphology of ACC was irregular and the growth of the tumor was amorphous in 17 cases, and the margin of the tumor was vague in 20 cases. (3)ACC often grew along the nerve with infiltration, which caused destruction of the skull base in 5 cases and atrophy of mastication muscles and/or buccinator in 3 cases. Conclusion: (1)The characteristics of cephalic and cervical adenoid cystic carcinoma on CT scans were ethmoid density, infiltrated growth, growing along the nerve with infiltration, and submucous growth. Among them, the most important manifestation, which could lead to the histologic diagnosis on CT, was ethmoid density. (2)The range of ACC was usually underestimated on CT. (3)The manifestation of tumor growth along the nerve could be apparently displayed on MRI

    In developed countries, there has been increased incidental detection of renal cell carcinoma (RCC). The incidence, pathological stage and survival of incidentally detected carcinoma in a developing country in Asia where, from 1990 to 1998, 165 renal cell carcinomas were identified. The clinical presentation, diagnostic-imaging modality employed, pathological staging and patient survival was reviewed. Incidental renal cancers included those that were diagnosed through health screening or detected incidentally through imaging studies for other conditions. The survival between these incidentally detected lesions and their symptomatic counterparts (suspected group) was compared. Sixty-four patients (39%) had their tumours detected incidentally, including 39 who were entirely asymptomatic and 25 who presented with non-specific symptoms, not initially suggestive of RCC. For the entire group, computed tomography provided the definitive diagnosis in 81% of cases. The incidental detection group had significantly smaller size of tumour (5.9 cm c.f. 7.6 cm), lower stage and lower histological grading. In particular, 78% of patients with incidental RCC had stage I or II diseases (TNM stage classification), compared with 57% of patients with suspected tumour (p c.f. 66% at last follow up; p < 0.05; log-rank test) over a mean follow up period of 33 months (range 1-91). Regression analysis showed that stage of disease was the only independent variable predictive of clinical outcome. In conclusion, that significant numbers of RCC were detected incidentally. These tumours were of a lower clinical pathological stage and had a better prognosis.

    Radioresistance often leads to poor survival in concurrent chemoradiotherapy-treated cervical squamous cell carcinoma, and reliable biomarkers can improve prognosis. We compared the prognostic potential of hemoglobin, absolute neutrophil count, and absolute lymphocyte count with that of squamous cell carcinoma antigen in concurrent chemoradiotherapy-treated squamous cell carcinoma. We analyzed 152 patients with concurrent chemoradiotherapy and high-dose-rate intracavitary brachytherapy-treated cervical squamous cell carcinoma. Hemoglobin, absolute neutrophil count, absolute lymphocyte count, and squamous cell carcinoma antigen were quantitated and correlated with survival, using Cox regression, receiver operating characteristic curve analysis, and Kaplan-Meier plots. Both hemoglobin and absolute lymphocyte count in the second week of concurrent chemoradiotherapy (Hb2 and ALC2) and squamous cell carcinoma antigen in the third week of concurrent chemoradiotherapy (mid-squamous cell carcinoma antigen) correlated significantly with disease-specific survival and progression-free survival. The ratio of high-dose-rate intracavitary brachytherapy dose to total dose (high-dose-rate intracavitary brachytherapy ratio) correlated significantly with progression-free survival. Patients with both low Hb2 (≤11 g/dL) and ALC2 (≤639 cells/µL) showed a lower 5-year disease-specific survival rate than those with high Hb2 and/or ALC2, regardless of mid-squamous cell carcinoma antigen (mid-squamous cell carcinoma antigen: ≤4.7 ng/mL; 5-year disease-specific survival rate: 85.5% vs 94.6%, p = 0.0096, and mid-squamous cell carcinoma antigen: >4.7 ng/mL; 5-year disease-specific survival rate: 43.8% vs 66.7%, p = 0.192). When both Hb2 and ALC2 were low, the low high-dose-rate intracavitary brachytherapy ratio (≤0.43) subgroup displayed significantly lower 5-year disease-specific survival rate compared to the subgroup high high-dose-rate intracavitary brachytherapy ratio (>0

    Inactivation of tumor suppressor p53 accompanies the majority of human malignancies. Restoration of p53 function causes death of tumor cells and is potentially suitable for gene therapy of cancer. In cervical carcinoma, human papilloma virus (HPV) E6 facilitates proteasomal degradation of p53. Hence, a possible approach to p53 reactivation is the use of small molecules suppressing the function of viral proteins. HeLa cervical carcinoma cells (HPV-18) with a reporter construct containing the b-galactosidase gene under the control of a p53-responsive promoter were used as a test system to screen a library of small molecules for restoration of the transcriptional activity of p53. The effect of the two most active compounds was studied with cell lines differing in the state of p53-dependent signaling pathways. The compounds each specifically activated p53 in cells expressing HPV-18 and, to a lesser extent, HPV-16 and exerted no effect on control p53-negative cells or cells with the intact p53-dependent pathways. Activation of p53 in cervical carcinoma cells was accompanied by induction of p53-dependent CDKN1 (p21), inhibition of cell proliferation, and induction of apoptosis. In addition, the two compounds dramatically decreased transcription of the HPV genome, which was assumed to cause p53 reactivation. The compounds were low-toxic for normal cells and can be considered as prototypes of new anticancer drugs. PMID:17685229

    We evaluated the feasibility of performing CT volumetry of gastric carcinoma (GC) and its correlation with TNM stage. This institutional review board-approved retrospective study was performed on 153 patients who underwent a staging CT study for histologically confirmed GC. CT volumetry was performed by drawing regions of interest including abnormal thickening of the stomach wall. Reproducibility of tumour volume (Tvol) between two readers was assessed. Correlation between Tvol and TNM/peritoneal staging derived from histology/surgical findings was evaluated using ROC analysis and compared with CT evaluation of TNM/peritoneal staging. Tvol was successfully performed in all patients. Reproducibility among readers was excellent (r = 0.97; P = 0.0001). The median Tvol of GC showed an incremental trend with T-stage (T1 = 27 ml; T2 = 32 ml; T3 = 53 ml and T4 = 121 ml, P volumetry may provide useful adjunct information for preoperative staging of GC. CT volumetry of gastric carcinoma is feasible and reproducible. Tumour volume 95.7 ml predicts metastatic gastric cancer with 87% sensitivity and 78.5% specificity (P = 0.0001). CT volumetry may be a useful adjunct for staging gastric carcinoma.

    Background: To exam the effect of radioactive iodine treatment for thyroid remnant ablation and/or distant metastasis. A total of 134 well-differentiated thyroid cancer patients with cervical lymphnode metastasis at the time of diagnosis were retrospectively reviewed at Chang Gung Medical Center in Taiwan from 1977 to 1995. Methods: Among them, 126 cases were papillary carcinomas and 8 cases were follicular carcinomas. The mean age was 37.0 ± 14.6 years old. After the operation, 127 (95 %) patients received 131 I treatment (mean dose: 146.6 ± 109.5 mCi, range 30 - 550 mCi) and long-term follow-up. The mean follow-up period is 5.9 ± 3.9 yrs. All patients were restage at the end of 1995. Clinical biochemical results were also analyzed. Results: Among 127 cases who received postoperative radioactive iodine treatment, the majority of cases (92.5 % in papillary ca. vs. 57.1 % in follicular ca.) improved to stage I, 11 (8.6 %) cases remained on the same disease and stages. 13 cases (10.2 %, 10 papillary and 3 follicular) deteriorated to stage III or IV. However, in the non-treatment group, only 33.3 % of papillary carcinoma patients improved to stage I and 16.7 % of the patients remained as stage II. There were 5 cases (3.7 %) of mortality. Two cases with stage IV papillary carcinomas died of metastatic or recurrent malignancy, and the other 2 cases with stage I or III papillary carcinomas died of tracheal cancer or valvular heart disease. One patient with stage IV follicular carcinoma died of cerebral vascular accident. Conclusions: Radioactive iodine ( 131 I) treatment plays a significant role in the management of well-differentiated thyroid carcinoma patients with cervical lymphnode metastasis. The effect of postoperative 131 I treatment on papillary carcinoma was better than that on follicular carcinoma. The optimal dosage and frequency of radioactive iodine treatment warrant further study. (author)

    OBJECTIVE To evaluate the role of whole-body {18F} fluro-2-dexoxyglucose (FDG) positron emission tomography (PET) scans in the detection of recurrent cervical cancer.METHODS Between June, 2000 and January, 2006, 25 patients had undergone a PET scan at the Peking Union Medical College Hospital to evaluate possible recurrent cervical cancer. All the PET findings were reviewed and compared to available clinical data to classify each PET scan result as a true positive, true negative, false positive, or false negative.RESULTS A total of 38 PET scans were conducted on the 25patients whose median age was 46 years. The Stage distributions were IA (n = 1), IB (n = 11), IIA (n = 5), IIB (n = 4), IIIB (n = 2), WB (n= 1), and unknown Stage (n = 1). There were 22 cases of squamous cell carcinoma and 3 cases of adenocarcinoma resulting in 9 true positive PET scans, 27 true negatives, 2 false positives and no false negatives. The sensitivity of the FDG PET scans for detecting recurrent cervical cancer was 100%, specificity 93.1%, positive predictive value 81.8%, and negative predictive value 100%.CONCLUSION The whole body FDG PET scans are a sensitive and specific imaging modality for the detection of recurrent cervical cancer. However the cost of PET scans is too high at this time. A large prospective study will determine whether this modality should be used routinely and take the place of other imaging methods in the early detection of recurrent cervical carcinoma

    Forty-four patients affected with thoracic esophageal carcinoma underwent preoperative CT to evaluate the value of this method in both staging and assessing the resectability of esophageal tumors. The authors compared the CTfindings with intraoperative macroscopei ones, pathologic, and bronchoscopic results in mid-high neoplasms. CT staging criteria were drawn from a careful review of literature and from personal experience. thirty-nine patients were submitted to surgery, and esophagectomy was possible in 34 of them. CT diagnostic accuracy was higher in proximal esophageal tumors than in sub-bronchial ones; as for the surgical choice, CT provided fundamental guidelines,especially if the choice was a blunt esophagectomy where it is important to exclude tumoral involvement of the airways (accuracy: 82.6%) or of the aorta (accuracy: 89.7%). CT staging accuracy was limited by the low sensitivity of the method in detecting lymphatic ( local: 66.6%, distant: 64.2%) and hepatic metastates. Combined thoraco-abdominal CT, tracheo-bronchoscopy and liver US, besides MR imgaging and endoscopic US, allow a better preoperative evaluation of esophageal carcinomas

    The aim of this study was to investigate the role of HPV 18 E6 and E7 gene products with respect to radiosensitivity of two cervical carcinoma cell lines. The two cervical carcinoma lines C4-1 and SW 756 were used in which treatment with dexamethasone allows to modulate expression levels of HPV 18 E6 and E7 genes: Upregulation in C4-1, down-regulation in SW 756. Effects of treatment with dexamethasone on plating efficiency and radiosensitivity were assessed using a clonogenic assay. Treatment with dexamethasone increased plating efficiency of the C4-1 cells, but did not affect plating efficiency of SW 756 cells. Treatment with dexamethasone induced enhanced radioresistance in both cell lines. Thus, in C4-1 cells the observed changes in radioresistance correlate to the enhancement in expression of HPV 18 genes E6/E7, whereas in SW 756, a reduced expression correlates negatively with the enhanced radioresistance.

    To assess the expression of MVP in cervix carcinoma patients treated by radiochemotherapy, its relation to clinical and pathologic prognostic factors and its role in predicting clinical outcome. In addition the relation to IGF-1R expression in this cohort of patients will be explored. Sixty consecutive patients suffering from localized cervix carcinoma were prospectively included in this study from July 1999 to December 2003. Follow-up was closed in November 2007. Patients were staged following the TNM classification. All patients received pelvic radiation (45-64.80 Gy in 1.8-2 Gy fractions) followed brachytherapy and concomitant cisplatin at 40 mg/m(2)/week doses. MVP expression was studied by immunohistochemistry in paraffin-embedded tumour tissue. MVP was expressed in 58 patients (96.7%) and no relation was found with clinicopathological variables. High MVP expression was related to high IGF1-R expression (p=0.023). Complete response after treatment was observed in 50 patients (83.3%). Clinical stage of the disease and clinical response to radiochemotherapy were the most important prognostic factors related to survival. High MVP and IGF-1R tumour expression was strongly related to poor local and regional disease-free survival (p=0.006), distant disease-free survival (p=0.050), disease-free survival (p=0.006), and cause-specific survival (p=0.007) in patients achieving a complete response. MVP and IGF-1R expression were related in clinical cervical tumours and confer reduced long-term local control in patients who achieved clinical complete response to radiochemotherapy.

    This study aimed to evaluate the ability of positron emission tomography with contrast-enhanced computed tomography to correctly stage head and neck squamous cell carcinomas, in comparison with pathological staging. Positron emission tomography computed tomography was used to determine the tumour-node-metastasis classification and overall cancer stage in 85 head and neck squamous cell carcinoma patients who underwent pre-operative imaging using this modality and primary surgery between July 2010 and January 2013. Staging by positron emission tomography computed tomography was retrospectively compared with staging using pathological specimens. Agreement between imaging stage and pathological stage was examined by univariate and multivariate analysis both overall and for each primary tumour site. This imaging modality was 87.5 per cent sensitive and 44.8 per cent specific in identifying regional cervical metastases, and had false positive and false negative rates of 18.8 per cent and 8.2 per cent, respectively. The positive predictive and negative predictive values were 75.4 per cent and 65.0 per cent, respectively. Univariate and multivariate analyses revealed a significant agreement between positron emission tomography computed tomography and pathological node classification in older patients and for the oral cavity primary tumour site. There was significant agreement between both methods in the overall classification only for tumours classified as T3 or greater. Positron emission tomography computed tomography should be used with caution for the pre-operative staging of head and neck cancers because of its high false positive and false negative rates.

    Cervical glandular neoplasias (CGN) present a challenge for cervical cancer prevention due to their complex histopathology and difficulties in detecting preinvasive stages with current screening practices. Reports of human papillomavirus (HPV) prevalence and type-distribution in CGN vary, providing...... uncertain evidence to support prophylactic vaccination and HPV screening. This study [108288/108290] assessed HPV prevalence and type-distribution in women diagnosed with cervical adenocarcinoma in situ (AIS, N = 49), adenosquamous carcinoma (ASC, N = 104), and various adenocarcinoma subtypes (ADC, N = 461...... of CGN are HPV16/18/45-positive, the incorporation of prophylactic vaccination and HPV testing in cervical cancer screening are important prevention strategies. Our results suggest that special attention should be given to certain rarer ADC subtypes as most appear to be unrelated to HPV....

    Objective: To assess the usefulness of computerized tomography (CT) in the characterization of renal masses, in order to stage them, determine their prognosis and their appropriate clinical and/or surgical management. Material and Methods: Between 1988 and 2001, we selected 63 patients with renal tumors that had been examined by pathology. Patient's ages ranged from 16 to 88 years (25 women, 38 men). The studies were performed with a sequential helical CT, using 5 mm thickness sections every 5mm evaluating the cortico medullar and nephrographic phases. Renal tumors were characterized and staged without any knowledge about the pathological findings; subsequently the tomographic characteristics were compared to such findings. The following characteristics were evaluated: 1) mixed solid-cystic nature; 2) size; 3) borders; 4) enhancement; 5) necrosis; 6) hemorrhage; 7) central scar; 8) presence of fat; 9) collecting system; 10) capsular invasion; 11) perirenal fat invasion; 12) vessels; 13) Gerota's fascia; 14) lymph nodes; and 15) local and/or distant metastases. Results: Of the 63 tumors, 2 were complicated cysts; of the 61 remaining tumors, 10 were angiomyolipomas, 1 was a renal lymphoma, 1 was a focal xantogranulomatose pyelonephritis, 1 was a metanephric adenoma, 3 papillary renal cell carcinoma (RCC), 4 transitional cell tumors, 4 oncocytomas, 37 clear cell renal carcinoma. The CT could correctly characterize the 2 cystic tumors as such, as well as the 9 angiomyolipomas and the 4 transitional cell tumors. The 48 other tumors (1 angiomyolipoma, 1 lymphoma, 1 focal xantogranulomatose pyelonephritis, 1 metanephric adenoma, 3 papillary RCC, 4 oncocytomas, and 37 cell renal carcinomas) remaining were characterized as renal adenocarcinomas and CT staged. Conclusion: CT is a useful method to characterize renal masses since it determines their solid-cystic or fatty structure; aiding in many cases to define a surgical treatment. For the CT staging of renal tumors, the

    The treatment outcome of advanced stage uterine cervical carcinoma remains unsatisfactory. In order to elaborate a novel trial within The Radiotherapy Cooperative Group (RCG) of the European Organization for Research and Treatment of Cancer (EORTC), we conducted a survey in 1997-1998 to determine the variability of pre-treatment assessment and treatment options. The variability of choosing surgery, defined radiation therapy techniques and chemotherapy are investigated, as well as the center's choices of future treatment strategies. Fifty two of 81 RCG centers from the RCG have participated in the survey. As one would expect, there is a large variation in the techniques used for pretreatment evaluation and treatment options. There is no 'standard' for reporting acute and late side effects. Chemotherapy is used neither systematically nor uniformly, and some centers continue to use neadjuvant chemotherapy modalities. Furthermore, the survey reveals that there is a strong demand for the reduction of overall treatment-time, for clinical investigation of novel combined modality treatment strategies, especially chemo-radiation therapy, and also for the use of new radiation sensitizers. We conclude that a more homogeneous approach to the pretreatment evaluation as well as treatment techniques is required in order to allow adequate quality control in any future trial of the RCG in the EORTC.

    To evaluate MR capacity in assessing deep myometrial and cervical infiltrations in cases of endometrial carcinoma. A series of 30 consecutively diagnosed endometrial cancer patients was pre-surgically evaluated by means of magnetic resonance (MR). TSE-T2 sequences with fat saturation and dynamic FFe sequence were used after gadolinium administration. A correlation with post-surgical histological stating was made. There were then determined sensitivity (S), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) for the deep myometrial infiltration and cervical invasion. Cases of overestimation and underestimation were analyzed. Values obtained for myometrium and cervix were, respectively, S of 67% and 63%, SP of 89% and 91%, PPV of 80% and 71% and NPV of 80% and 87%. Two cases each were over valued for myometrial infiltration and cervix: four cases and 3 cases, respectively, were undervalues. MR stating in cases of endometrial carcinoma is a highly reliable diagnostic technique, but it does present certain limitations. (Author) 19 refs.

    Orton, C.G.

    1998-01-01

    For the brachytherapy component of the r[iation treatment of cervical carcinoma, high dose rate (HDR) is slowly replacing conventional low dose rate (LDR) due primarily to r[iation safety and other physical benefits attributed to the HDR modality. Many r[iation oncologists are reluctant to make this change because of perceived r[iobiological dis[vantages of HDR. However, in clinical practice HDR appears to be as effective as LDR but with a lower risk of late complications, as demonstrated by one randomized clinical trial and two comprehensive literature and practice surveys. The reason for this appears to be that the r[iobiological dis[vantages of HDR are outweighed by the physical [vantages. (orig.)

    Cervical cancer is the most prevalent malignancy in sub-Saharan Africa (SSA) with many women only seeking professional help when they are experiencing symptoms, implying late-stage malignancy and higher mortality rates. This ecological study assesses population-level exposures of SSA women to the numerous risk factors for HPV infection and cervical cancer, against late-stage presentation of cervical cancer. A literature review revealed the relevant risk factors in SSA. Open-access databases were mined for variables closely representing each risk factor. A proxy for late-stage presentation was used (ratio of incidence-to-mortality, IMR), and gathered from IARC's GLOBOCAN 2012 database. Variables showing significant correlation to the IMR were used in stepwise multiple regression to quantify their effect on the IMR. Countries with high cervical cancer mortality rates relative to their incidence have an IMR nearer one, suggesting a larger proportion of late-stage presentation. Western Africa had the lowest median IMR (1.463), followed by Eastern Africa (IMR = 1.595) and Central Africa (IMR = 1.675), whereas Southern Africa had the highest median IMR (1.761). Variables selected for the final model explain 65.2% of changes seen in the IMR. Significant predictors of IMR were GDP (coefficient = 2.189 × 10 -6 , p = 0.064), HIV infection (-1.936 × 10 -3 , p = 0.095), not using a condom (-1.347 × 10 -3 , p = 0.013), high parity (-1.744 × 10 -2 , p = 0.008), and no formal education (-1.311 × 10 -3 , p < 0.001). Using an IMR enables identification of factors predicting late-stage cervical cancer in SSA including: GDP, HIV infection, not using a condom, high parity and no formal education.

    The present study was conducted to clarify the role of carbon-11 choline ( 11 C-choline) positron emission tomography (PET)/computed tomography (CT) in the management of uterine carcinoma. Twenty-two patients who underwent 11 C-choline PET/CT and pelvic MRI were evaluated retrospectively. The images were reviewed by a board-certified radiologist and a nuclear medicine specialist who were unaware of any clinical information, and a consensus was reached. Diagnostic accuracy of PET/CT was evaluated for staging. The reference standard consisted of histological examination (n=17) and follow-up conventional CT (n=5). In five patients with cervical carcinoma, 11 C-choline PET/CT was performed before and after treatment that consisted of cisplatin infusion and subsequent radiotherapy. Standardized uptake value (SUV) was compared with unidimensional and volumetric measurements that were made on magnetic resonance images (MRI) before and after treatment. Based on PET/CT interpretations, the reviewers correctly classified tumor (T) stage in 8 patients (47%), nodes (N) stage in 21 patients (96%), metastasis (M) stage in 20 patients (91%), and tumor, nodes and metastasis (TNM) stage in 15 patients (88%). Tumor size, volume, and SUV decreased after treatment in five patients with cervical carcinoma. Using the Pearson correlation test, a significant correlation was found between the reduction rate of SUV and reduction rate of tumor volume. 11 C-choline PET/CT is an accurate means for the management of patients with uterine carcinoma. The combination of 11 C-choline PET/CT and MRI increases the accuracy of staging in patients with uterine carcinoma. (author)

    It was possible to check the information obtained by CT scanning in 36 patients out of 49 who had been subjected to computerized tomography, in respect of the extension of the primary tumour (T stage), and in 25 patients in respect of the degree of mediastinal lymphatic node involvement (N stage). In all 49 patients, the presence of bronchogenic carcinoma had been safely established. In 97% of the cases, assessment of the extension of the primary tumour was found to be correct. Assessment of the N stage, however, is more problematic, since detection of mediastinal lymphatic nodes by computerized tomography does not necessarily tell us something about their metastatic involvement. If all recognizable lymphatic nodes are interpreted as potential metastases, we have no false negative but 61% false positive results because of the frequency of postinflammatory or anthracotic lymphatic nodes. In case of exclusive assessment of lymphatic node enlargement above 1 cm diameter, the rate of metastatic nodes increases considerably (83%). Computerized tomography is definitely superior to all roentgenological methods in assessing the stage of a bronchogenic carcinoma; hence, it could occupy a key position in determining the diagnostic and therapeutic approach in patients with this disease.

    Full Text Available Background: Urinary bladder cancer is classified as urothelial or non-urothelial. Ninenty percent of bladder cancer are urothelial and has propensity for divergent differentiation. Squamous differentiation is associated with unfavourable prognostic features. The aim of this study is to determine the significance of urothelial carcinoma with divergent differentiation in relation to tumor stage and lymphovascular as well as perineural invasion in radical cystectomy and partial cystectomy specimen.Materials and methods: This prospective study was done among 51 patients who underwent radical cystectomy or partial cystectomy at Bhaktapur Cancer Hospital from 1st August 2013 to 31st December 2015. Received specimen was grossed following standard protocol and histopathological evaluation was done in relation to tumor type, depth of invasion, Lymphovascular and perineural invasion.Results: Pure urothelial carcinoma comprises 47.1% of cases. Among the divergent differentiation, urothelial carcinoma with squamous differentiation was the commonest one (39.2% followed by glandular differentiation (5.9%, sarcomatoid differentiation (3.9%, clear cell variant (2.0% and squamous along with sarcomatoid variant (2.0%. Statistical significant correlation was found between urothelial carcinoma with divergent differentiation and tumor stage (p<0.012. Statistically significant correlation was also found between urothelial carcinoma with divergent differentiation and lymphovascular invasion (p=0.012 as well as perineural invasion (p=0.037.Conclusion:  Most common divergent differentiation was squamous differentiation. Urothelial carcinoma with divergent differentiation was associated with higher stage and lymphovascular as well as perineural invasion. So it is mandatory to search for the divergent differentiation in urothelial carcinoma as this may be associated with unfavourable prognosis.

    To determine the frequency of occult (node negative) cervical lymph node metastasis in primary head and neck squamous cell carcinoma, using contrast enhanced computed tomography (CT). Study Design: Cross sectional descriptive study. Place and Duration of Study: Study was conducted in Department of Radiology, Combined Military Hospital Rawalpindi. Duration of the study was 06 months i.e. from 19th February 2011 to 19th August 2011. Patients and Methods: A total of 141 cases, fulfilling the inclusion criteria, reporting to the radiology department, were included in the study after seeking written informed consent. All patients underwent contrast enhanced CT scan of the neck from base of skull to root of neck using Asteion Whole Body X-ray CT Scanner (Model TSX-021A). Images were evaluated for the presence or absence of cervical lymph node metastasis according to the cervical lymph node metastatic criteria at each level of the neck. Results: Of the 141 patients with clinically no head and neck squamous cell carcinoma, 45.4% were found to have lymph node metastases. Frequency of occult metastases in squamous cell carcinoma of oral cavity was 47.6%, oropharynx 23.5%, larynx 33.3% and hypopharynx 78.6%. Conclusion: In clinically node negative neck, the risk of lymph node metastases is significantly high in patients of head and neck squamous cell carcinoma in our population. All patients presenting with node negative neck should undergo CT scans for early detection of occult metastasis. (author)

    Abstract Background High interstitial fluid pressure (IFP) in the primary tumor is associated with poor disease-free survival in locally advanced cervical carcinoma. A noninvasive assay is needed to identify cervical cancer patients with highly elevated tumor IFP because these patients may benefit from particularly aggressive treatment. It has been suggested that dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with gadolinium diethylene-triamine penta-acetic acid (Gd-DTPA) as c...

    The objective of this study was to evaluate the prognostic value of anemia in uterine cervical carcinoma patients treated with irradiation. A total of 162 patients diagnosed with stage IIA-IIIB cervical carcinoma by the criteria of International Federation of Gynecology and Obstetrics and treated with irradiation were analyzed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. Patients were divided into two groups according to the hemoglobin level before treatment: 10 mm) assessed by computed tomography had impact on overall survival (p=0.008), disease-free survival (p=0.023) and relapse-free survival (p=0.028). Using multivariate analysis, the hemoglobin level before treatment was found to be an independent prognostic factor for overall survival (p=0.001), disease-free survival (p=0.040) and local relapse-free survival (p=0.013); Iymph node status assessed by computed tomography had impact on overall survival (p=0.030) and local relapse-free survival (p=0.038). Hemoglobin level before treatment is a significant prognostic factor for patients with uterine cervical carcinoma treated with irradiation. (author)

    The central objective of this investigation was to focus on the development of the cervical spine observed by lateral cephalometric radiological images of children and adolescents (6-16 years old). A sample of 26 individuals (12 girls and 14 boys) was classified according to stages of cervical spine maturation in two subcategories: group I (initiation phase) and group II (acceleration phase). The morphology of the cervical spine was assessed by lateral cephalometric radiographs obtained in accordance with an innovative method for establishing a standardized head posture. A total of 29 linear variables and 5 angular variables were used to clarify the dimensions of the cervical vertebrae. The results suggest that a few measurements can be used as parameters of vertebral maturation both for males and females. The aforementioned measurements include the inferior depth of C2-C4, the inferior depth of C5, the anterior height of C4-C5, and the posterior height of C5. We propose original morphological parameters that may prove remarkably useful in the determination of bone maturational stages of the cervical spine in children and adolescents.

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

Materials and methods: This article screened the abstract and full-text papers that investigated salivary gland primary ACC of head and neck. Two independent reviewers searched for articles published before October 2017 in three databases (Web of Science, PubMed, and Ovid, having no limits in date and language. Statistical data were analyzed statistically by Review Manager 5.3. Results: In total, 18 studies involving 2993 patients were included in the analysis. Of the 2993 patients, 473 patients had cervical lymph node metastasis, with a merge frequency of 16% (95% CI: 13–19. Among included articles, only 4 involved cervical lymph node occult metastases, with a merge frequency of 14% (95% CI: 9–20. There were 5 articles containing minor salivary glands (MiSGs involving 370 patients of which 92 patients had cervical lymph node metastases and the merge frequency was 25% (95% CI: 11–38. Moreover, there were 4 studies on major salivary glands involving 904 patients of which 158 patients had cervical lymph node metastases and the merge frequency was 17% (95% CI: 15–20. Conclusion: Elective neck dissection is unnecessary for all patients with salivary gland ACC of head and neck. Moreover, compared with major salivary glands, MiSGs have a higher cervical lymph node metastases rate in ACC. The overall cervical lymph node metastases rate of MiSGs is 25%, which is enough to attract our attention. Therefore, we suggest that neck dissection might be

    Coplanar extended-field intensity-modulated radiation therapy (EF-IMRT) targeting the whole-pelvic and para-aortic lymph nodes in patients with advanced cervical cancer results in impaired creatinine clearance. An improvement in renal function cannot be expected unless low-dose (approximately 10 Gy) kidney exposure is reduced. The dosimetric method should be considered during EF-IMRT planning to further reduce low-dose exposure to the kidneys. To assess the usefulness of non-coplanar EF-IMRT with kidney-avoiding beams to spare the kidneys during cervical carcinoma treatment in dosimetric analysis between non-coplanar and coplanar EF-IMRT, we compared the doses of the target organ and organs at risk, including the kidney, in 10 consecutive patients. To estimate the influence of EFRT on renal dysfunction, creatinine clearance values after treatment were also examined in 18 consecutive patients. Of these 18 patients, 10 patients who were included in the dosimetric analysis underwent extended field radiation therapy (EFRT) with concurrent chemotherapy, and eight patients underwent whole-pelvis radiation therapy with concurrent chemotherapy to treat cervical carcinoma between April 2012 and March 2015 at our institution. In the dosimetric analysis, non-coplanar EF-IMRT was effective at reducing low-dose (approximately 10 Gy) exposure to the kidneys, thus maintaining target coverage and sparing other organs at risk, such as the small bowel, rectum, and bladder, compared with coplanar EF-IMRT. Renal function in all 10 patients who underwent EFRT, including coplanar EF-IMRT (with kidney irradiation), was low after treatment, and differed significantly from that of the eight patients who underwent WPRT (no kidney irradiation) 6 months after the first day of treatment (P = 0.005). In conclusion, non-coplanar EF-IMRT should be considered in patients with advanced cervical cancer, particularly in patients with a long life expectancy or with pre-existing renal dysfunction.

    Most cervical cancer patients worldwide receive surgical treatments, and yet the current International Federation of Gynecology and Obstetrics (FIGO) staging system do not consider surgical-pathologic data. We propose a more comprehensive and prognostically valuable surgical-pathologic staging and scoring system (SPSs). Records from 4,220 eligible cervical cancer cases (Cohort 1) were screened for surgical-pathologic risk factors. We constructed a surgical-pathologic staging and SPSs, which was subsequently validated in a prospective study of 1,104 cervical cancer patients (Cohort 2). In Cohort 1, seven independent risk factors were associated with patient outcome: lymph node metastasis (LNM), parametrial involvement, histological type, grade, tumor size, stromal invasion, and lymph-vascular space invasion (LVSI). The FIGO staging system was revised and expanded into a surgical-pathologic staging system by including additional criteria of LNM, stromal invasion, and LVSI. LNM was subdivided into three categories based on number and location of metastases. Inclusion of all seven prognostic risk factors improves practical applicability. Patients were stratified into three SPSs risk categories: zero-, low-, and high-score with scores of 0, 1 to 3, and ≥4 (P=1.08E-45; P=6.15E-55). In Cohort 2, 5-year overall survival (OS) and disease-free survival (DFS) outcomes decreased with increased SPSs scores (P=9.04E-15; P=3.23E-16), validating the approach. Surgical-pathologic staging and SPSs show greater homogeneity and discriminatory utility than FIGO staging. Surgical-pathologic staging and SPSs improve characterization of tumor severity and disease invasion, which may more accurately predict outcome and guide postoperative therapy.

    To determine the diagnostic performance of hematuria as a screening test for urinary bladder infiltration in cervical cancer patients with a prospective study design. Newly diagnosed cervical cancer patients at Srinagarind hospital from 14 June 2011 to 30 April 2012 were enrolled in this study. We collected midstream urine samples for urinalysis from every patient before routine cystoscopic exam for clinical staging. The presence of 3 or more red blood cells (RBCs) per high power field was defined as positive for hematuria. A two-by-two table was used to determine the diagnostic performance of hematuria to detect urinary bladder mucosal infiltration using cystoscopy and biopsy as the gold standard. A total of 130 were patients included, 54 of which (41.5%) had hematuria. Of these, four patients (3.08%) had pathological report from cystoscopic biopsy confirmed metastatic squamous cell carcinoma. The sensitivity, specificity, PPV, NPV, and accuracy of hematuria as a screening test to detect urinary bladder mucosal infiltration of cervical cancer were 100%, 60.3%, 7.4%, 100%, and 61.5%, respectively. There was no single case of urinary bladder mucosal infiltration in patients initially staged less than stage III. Hematuria can be used as a screening test to detect urinary bladder mucosal infiltration of cervical cancer. This can reduce the number of cervical cancer patients who really need to undergo cystoscopy as a staging procedure to less than half and to less than 20% if stage III or more were included without missing a single case of urinary bladder mucosal infiltration.

    Endometrial carcinoma is one of the most common gynecologic malignancies and which is predominant in postmenopausal women. Clinically many patients are hospitalized in early stage due to clinical sign and symptom such as vaginal bleeding and in this case, patient's prognosis is known to be good. However, considerable number of patients with advanced and relapsed disease reveal poor prognosis. Therefore, exact staging work up is essential for proper treatment as is primary lesion detection. 18 F-FDG-PET has been widely used for the evaluation of gynecologic malignancies such as cervical carcinoma and ovarian cancer. In contrast, FDG PET application to endometrial carcinoma is limited until now and there is no sufficient data to validate the usefulness of FDG PET for this disease yet. However, several studies showed promising results that FDG PET is sensitive and specific in detection of recurrent or metastatic lesions. Therefore further active investigation in this field can facilitate the use of FDG PET for endometrial carcinoma

    To design clear guidelines for the staging and follow-up of patients with uterine cervical cancer, and to provide the radiologist with a framework for use in multidisciplinary conferences. Methods: Guidelines for uterine cervical cancer staging and follow-up were defined by the female imaging subcommittee of the ESUR (European Society of Urogenital Radiology) based on the expert consensus of imaging protocols of 11 leading institutions and a critical review of the literature. The results indicated that high field Magnetic Resonance Imaging (MRI) should include at least two T2-weighted sequences in sagittal, axial oblique or coronal oblique orientation (short and long axis of the uterine cervix) of the pelvic content. Axial T1-weighted sequence is useful to detect suspicious pelvic and abdominal lymph nodes, and images from symphysis to the left renal vein are required. The intravenous administration of Gadolinium-chelates is optional but is often required for small lesions (<2 cm) and for follow-up after treatment. Diffusion-weighted sequences are optional but are recommended to help evaluate lymph nodes and to detect a residual lesion after chemoradiotherapy. Expert consensus and literature review lead to an optimized MRI protocol to stage uterine cervical cancer. MRI is the imaging modality of choice for preoperative staging and follow-up in patients with uterine cervical cancer. (orig.)

    The purpose of this study was to investigate the application of histogram analysis of apparent diffusion coefficient (ADC) in characterizing pathologic features of cervical cancer and benign cervical lesions. This prospective study was approved by the institutional review board, and written informed consent was obtained. Seventy-three patients with cervical cancer (33-69 years old; 35 patients with International Federation of Gynecology and Obstetrics stage IB cervical cancer) and 38 patients (38-61 years old) with normal cervix or cervical benign lesions (control group) were enrolled. All patients underwent 3-T diffusion-weighted imaging (DWI) with b values of 0 and 800 s/mm(2). ADC values of the entire tumor in the patient group and the whole cervix volume in the control group were assessed. Mean ADC, median ADC, 25th and 75th percentiles of ADC, skewness, and kurtosis were calculated. Histogram parameters were compared between different pathologic features, as well as between stage IB cervical cancer and control groups. Mean ADC, median ADC, and 25th percentile of ADC were significantly higher for adenocarcinoma (p = 0.021, 0.006, and 0.004, respectively), and skewness was significantly higher for squamous cell carcinoma (p = 0.011). Median ADC was statistically significantly higher for well or moderately differentiated tumors (p = 0.044), and skewness was statistically significantly higher for poorly differentiated tumors (p = 0.004). No statistically significant difference of ADC histogram was observed between lymphovascular space invasion subgroups. All histogram parameters differed significantly between stage IB cervical cancer and control groups (p histogram analysis may help to distinguish early-stage cervical cancer from normal cervix or cervical benign lesions and may be useful for evaluating the different pathologic features of cervical cancer.

    To assess the diagnostic value of integrated PET/MRI for whole-body staging of cervical cancer patients, as well as to investigate a potential association between PET/MRI derived functional parameters and prognostic factors of cervical cancer. The present study was approved by the local institutional review board. Twenty-seven patients with histopathologically confirmed cervical cancer were prospectively enrolled in our study. All patients underwent a whole-body PET/MRI examination after written informed consent was obtained. Two radiologists separately evaluated the PET/MRI data sets regarding the determination of local tumor extent of primary cervical cancer lesions, as well as detection of nodal and distant metastases. Furthermore, SUV and ADC values of primary tumor lesions were analyzed and correlated with dedicated prognostic factors of cervical cancer. Results based on histopathology and cross-sectional imaging follow-up served as the reference standard. PET/MRI enabled the detection of all 27 primary tumor lesions of the uterine cervix and allowed for the correct determination of the T-stage in 23 (85 %) out of the 27 patients. Furthermore, the calculated sensitivity, specificity and diagnostic accuracy for the detection of nodal positive patients (n = 11) were 91 %, 94 % and 93 %, respectively. PET/MRI correctly identified regional metastatic disease (N1-stage) in 8/10 (80 %) patients and non-regional lymph node metastases in 5/5 (100 %) patients. In addition, quantitative analysis of PET and MRI derived functional parameters (SUV; ADC values) revealed a significant correlation with pathological grade and tumor size (p < 0.05). The present study demonstrates the high potential of integrated PET/MRI for the assessment of primary tumor and the detection of lymph node metastases in patients with cervical cancer. Providing additional prognostic information, PET/MRI may serve as a valuable diagnostic tool for cervical cancer patients in a pretreatment setting

    We have previously shown that the HIV protease inhibitor lopinavir has selective toxicity against human papillomavirus (HPV)-positive cervical carcinoma cells via an unknown mechanism. SiHa cervical carcinoma cells were stably transfected with the proteasome sensor vector pZsProSensor-1 to confirm lopinavir inhibits the proteasome in these cells. The Panorama Xpress profiler 725 antibody array was then used to analyse specific changes in protein expression in lopinavir-treated versus control untreated SiHa cells followed by PCR and western blotting. Colorimetric growth assays of lopinavir-treated E6/E7 immortalised versus control human keratinocytes were performed. Targeted small interfering RNA gene silencing followed by growth assay comparison of lopinavir-treated/untreated SiHa cells was also used. Lopinavir induced an increase in the fluorescence of pZsProSensor-1 transfected SiHa cells, indicative of proteasomal inhibition. Ribonuclease L (RNASEL) protein was shown to be up-regulated in lopinavir-treated SiHa cells, which was confirmed by PCR and western blot. Targeted silencing of RNASEL reduced the sensitivity of SiHa cells to lopinavir. Selective toxicity against E6/E7 immortalised keratinocytes versus control cells was also seen with lopinavir and was associated with up-regulated RNASEL expression. These data are consistent with the toxicity of lopinavir against HPV-positive cervical carcinoma cells being related to its ability to block viral proteasome activation and induce an up-regulation of the antiviral protein RNASEL. This is supported by the drug's selective toxicity and up-regulation of RNASEL in E6/E7 immortalised keratinocytes combined with the increased resistance to lopinavir observed in SiHa cells following silencing of RNASEL gene expression.

    Accumulating evidences had demonstrated that the CD97, a member of the epidermal growth factor 7-transmembrane family, and its cellular ligand decay accelerating factor (DAF) both play important roles in tumor dedifferentiation, migration, invasiveness, and metastasis. However, the roles of CD97 and DAF in human cervical squamous cell carcinoma (CSCC) have not been investigated. The purpose of this study was to observe the expression profile of CD97 and DAF in CSCC and evaluate their clinical significance. Immunohistochemistry was used to investigate the expression of CD97 and DAF proteins in 97 patients with CSCC and 53 patients with cervical intraepithelial neoplasia, a precursor lesion of CSCC. CD97 and DAF were absent or only weakly expressed in the normal epithelium of the cervix but were present in 83.5% (81/97) and 90.7% (88/97) of CSCC samples, respectively. Overexpression of CD97 was significantly associated with a high International Federation of Gynecology and Obstetrics stage (P=0.010) and lymph node metastasis (P=0.026). The majority of CSCCs, irrespective of staging/grading classification, displayed strong DAF immunostaining. Kaplan-Meier survival analysis revealed that overexpression of CD97 was associated with a worse prognosis. Multivariate analyses showed that the International Federation of Gynecology and Obstetrics stage (P=0.000), lymph node metastasis (P=0.004), and CD97 expression (P=0.040) were independent risk factors for overall survival. The present study suggested that the expressions of CD97 and DAF were both upregulated in CSCC. The expression level of CD97 in CSCC was associated with the severity of the tumor. Furthermore, CD97 might be an independent poor prognostic factor for CSCC patients.

    In this study, a homogeneous polysaccharide (LEP1) with an average molecular weight of 53kDa was successfully purified from the fruiting bodies of Lentinus edodes and its anticancer efficacy on human cervical carcinoma HeLa cells in vitro and associated possible molecular mechanism were also evaluated. MTT assay showed that LEP1 exhibited a dose-dependent inhibitory effect on the proliferation of HeLa cells and caused apoptotic death. Our present findings provided the first evidence that LEP1 induced the apoptosis of HeLa cells via a mitochondria dependent pathway, as indicated by an increase in Bax/Bcl-2 ratio, a loss of mitochondrial membrane potential (Δym), the release of cytochrome c from the mitochondria to the cytosol, activation of caspase-9 and caspase-3, and cleavage of poly (ADP-ribose) polymerase (PARP) in HeLa cells. These combined results unequivocally indicated that the involvement of mitochondria-mediated signaling pathway in LEP1-induced apoptosis and strongly provided experimental evidence for the use of LEP1 as a potential therapeutic agent in the prevention and treatment of human cervical carcinoma.

    To characterize histopathological status, high-risk human papillomavirus (hr-HPV) infection status, and associated risk factors in patients with atypical squamous cells of undetermined significance (ASCUS). Cervical biopsies obtained from 130 ASCUS patients were subjected to histopathological examination and hr-HPV testing. Associations between advanced lesions and hr-HPV load or age were analyzed, and the confounding factors for high-grade cervical lesions were identified. Cervical biopsies from ASCUS patients had a wide range of pathological states, ranging from normal to invasive cervical carcinoma. High-risk HPV infection was significantly associated with advanced cervical lesions in ASCUS patients; hr-HPV infection and the number of gestations were risk factors for developing advanced cervical disease. A significant portion of ASCUS patients harbor advanced cervical lesions. The number of gestations and hr-HPV infection can increase the risk of developing advanced cervical lesions in ASCUS patients.

    To assess the clinical value of proton ( 1 H) MR spectroscopy in cervical carcinomas, in the prediction of poor prognostic human papillomavirus (HPV) genotypes as well as persistent disease following concurrent chemoradiotherapy (CCRT). 1 H MR spectroscopy using external phase array coil was performed in 52 consecutive cervical cancer patients at 3 Tesla (T). Poor prognostic HPV genotypes (alpha-7 species or absence of HPV infection) and persistent cervical carcinoma after CCRT were recorded. Statistical significance was calculated with the Mann-Whitney two-sided nonparametric test and areas under the receiver operating characteristics curve (AUC) analysis. A 4.3-fold (P = 0.032) increased level of methyl resonance at 0.9 ppm was found in the poor prognostic HPV genotypes, mainly attributed to the presence of HPV18, with a sensitivity of 75%, a specificity of 81%, and an AUC of 0.76. Poor prognostic HPV genotypes were more frequently observed in patients with adeno-/adenosquamous carcinoma (Chi-square, P < 0.0001). In prediction of the four patients with persistent disease after CCRT, elevated methyl resonance demonstrated a sensitivity of 100%, a specificity of 74%, and an AUC of 0.82. 1 H MR spectroscopy at 3T can be used to depict the elevated lipid resonance levels in cervical carcinomas, as well as help to predict the poor prognostic HPV genotypes and persistent disease following CCRT. Further large studies with longer follow up times are warranted to validate our initial findings. 1 J. Magn. Reson.

    Objective: To evaluate the transarterial chemoembotherapy in the treatment of advanced or late staged digestive tract carcinoma. Methods: One hundred fifty-one patients with advanced or late staged digestive tract carcinoma (including 20 cases of esophageal carcinoma, 29 cases of cardia carcinoma, 71 cases of gastric carcinoma and 31 cases of large intestinal carcinoma) underwent super selective transarterial chemoembotherapy. Results: Interventions were successful. Symptoms were apparently improved in all cases. Decreased diameter of tumor was seen in all cases. Half-year survival rate was 95% (144/151); one year survival was 86% (130/150); two year survival rate was 66% (99/151); and three year survival rate was 29% (44/151). Conclusion: The transarterial chemoembotherapy is an effective treatment of advanced or late staged digestive tract carcinoma. In patients with metastases, the intervention is especially valuable for both primary and metastatic lesions

    OBJECTIVE: The aim of this cross sectional study was to assess serum insulin-like growth factor-1 (IGF-1) levels in female and male subjects at various cervical vertebral maturation (CVM) stages. MATERIAL AND METHODS: The study sample consisted of 60 subjects, 30 females and 30 males, in the age range of 8-23 years. For all subjects, serum IGF-1 level was estimated from blood samples by means of chemiluminescence immunoassay (CLIA). CVM was assessed on lateral cephalograms using the method described by Baccetti. Serum IGF-1 level and cervical staging data of 30 female subjects were included and taken from records of a previous study. Data were analyzed by Kruska-Wallis and Mann Whitney test. Bonferroni correction was carried out and alpha value was set at 0.003. RESULTS: Peak value of serum IGF-1 was observed in cervical stages CS3 in females and CS4 in males. Differences between males and females were observed in mean values of IGF-1 at stages CS3, 4 and 5. The highest mean IGF-1 levels in males was observed in CS4 followed by CS5 and third highest in CS3; whereas in females the highest mean IGF-1 levelswas observed in CS3 followed by CS4 and third highest in CS5. Trends of IGF-1 in relation to the cervical stages also differed between males and females. The greatest mean serum IGF-1 value for both sexes was comparable, for females (397 ng/ml) values were slightly higher than in males (394.8 ng/ml). CONCLUSIONS: Males and females showed differences in IGF-1 trends and levels at different cervical stages. PMID:25992990

    This is a retrospective analysis of the results of 24 patients with bulky stage 2 carcinoma of the cervix treated with full course irradiation followed by adjunctive surgery between 1975 and 1980. A review of the surgical specimens following irradiation showed that 12 patients had no residual cancer, five had only microscopic foci of cancer, and five had extensive residual cancer. Two patients had unresectable persistent cancer. Six patients had histological evidence of lymph node metastases prior to irradiation. The surgical-pathological findings following irradiation had important prognostic implications. All five patients with extensive residual cancer in the surgical specimen recurred, 2 of 5 patients with only microscopic foci of residual cancer and, none of the 12 patients with no residual cancer in the resected specimens developed a recurrence. Lymph node involvement was not associated with an increased incidence of recurrence. Most patients with residual cancer following full course irradiation recurred locally. Thus the addition of adjunctive surgery following full course irradiation did not significantly improve the treatment results of patients with bulky stage 2 carcinoma of the cervix.

    Differentiated thyroid carcinoma staging is increasingly important due to the current trends to a less intensive therapy in low-risk patients. The TNM system is most widely used, but other systems based on follow-up of several patient cohorts have been developed. When these systems have been applied to other populations, results have been discordant. Our study evaluates the suitability of several differentiated thyroid carcinoma staging systems in a Spanish population. 729 patients with differentiated thyroid carcinoma and staging data available were enrolled. Mean follow-up time was 10.8 years. The TNM, EORTC, AMES, Clinical class, MACIS, Ohio, NTCTCS, and Spanish systems were applied to all histological types. The Kaplan-Meier survival curves for each system were analyzed, and compared using the proportion of explained variation (PEV). The demographic and clinical characteristics of our population were similar to those of other Spanish and international cohorts reported. The best systems were NTCTCS, with 74.7% PEV, and TNM (68.3%), followed by the Ohio, MACIS, EORTC, and AMES systems with minimal differences between them, while the least adequate were the Spanish (55.2%) and Clinical class (47.1%) systems. The NTCTCS staging system was found to be better than TNM in our population but, because of its simplicity and greater dissemination, the TNM appears to be recommended for staging of patients with differentiated thyroid carcinoma.

    Surgery with staging using FIGO (1988) classification is accepted management for stage III endometrial carcinoma. The delivery of adjuvant therapy is controversial and tends to be individualised. Retrospective review of stage III endometrial carcinoma patients who underwent radical surgery at the Royal Adelaide and Queen Elizabeth Hospitals from 1984 to 2003 was carried out. Medical records were reviewed for details of patient characteristics, surgery, histopathology, adjuvant therapy and recurrence/survival. Sixty-six patients with a median age of 69 (37-97), had a median follow-up of 26 months (1-188 ). For all stage III patients, the actuarial 5-year disease-free and overall survivals were 50 and 43% respectively. Thirty-five patients received pelvic +/- paraaortic radiotherapy, 5 whole abdominal radiotherapy, 14 vaginal brachytherapy boost, 10 chemotherapy and 13 adjuvant hormones. Forty-six percent of patients recurred in a median time of 13 months (0-95). For these patients, the sites of first recurrence were pelvis in 27%, pelvis and abdomen in 23%, abdomen alone in 13%, distant alone in 27%, distant and abdominal in 7% and all three sites in 3%. On univariate analysis disease-free survival was impacted by; age, grade, parametrial involvement, number of extrauterine sites, lymphovascular invasion, adjuvant radiotherapy to the pelvis alone and postoperative macroscopic residual disease. Lymphovascular invasion, post-operative residual disease and adjuvant pelvic radiotherapy remained significant on multivariate analysis. These outcomes for stage III endometrial carcinoma are comparable to the current literature. Ongoing research is required to establish the most appropriate adjuvant therapy in these high risk patients

    Background. Cervical carcinoma is the only gynecological tumor still being staged mainly by clinical examination and only a limited use of diagnostic radiology. Cross sectional imaging is increasingly used as an aid in the staging procedure. We wanted to assess the impact of magnetic resonance imaging (MRI) in addition to the clinical staging of patients with carcinoma of the uterine cervix. Material and methods. A retrospective single-centre analysis of 183 women referred to a tertiary referral centre for gynecological tumors (<= 65 years old) with cervical cancer diagnosed between January 1, 2003 and December 31, 2006 who have undergone an MRI investigation before start of treatment. Patient records were retrospectively reviewed and any change of the planned treatment after the MRI examination was noted. Results. In patients with cervical carcinoma FIGO stage Ia2-IIa treated surgically, the treatment plan was altered due to MRI results in 10/125 patients. In the smaller group of patients with clinically more advanced disease receiving radio-chemotherapy, the treatment plan was altered in 12/58 patients. Reasons for changing the treatment plan after MRI were findings indicating a higher (n = 8) or lower (n = 5) local tumor stage, findings of para aortic nodal disease (n = 4) or difficulty to clinically examine the patient due to obesity (n = 2). MRI was also an aid in deciding whether or not to offer fertility preserving treatment in three cases. Conclusion. The use of MRI affects treatment planning in patients with cancer of the uterine cervix. The impact is more obvious in more advanced stages of disease and in patients who are difficult to examine clinically due to, for example body constitution. The result of MRI is also an aid in deciding whether or not a fertility preserving operation is feasible

    The majority of squamous cell carcinomas of cervix are preceded by visible changes in the cervix, most often detected by cervical smear. As cervical cancer is preceded by long precancerous stages, identification of the high-risk population through detection of DNA ploidy may be of importance in effective management of this disease. Here we attempted to correlate aneuploidy DNA patterns and their influence on biological behavior of flow-cytometry analysis of DNA ploidy which was carried out in cytologically diagnosed cases of mild (79), moderate (36), and severe (12) dysplasia, as well as “atypical squamous cells of unknown significance (ASCUS)” (57) along with controls (69), in order to understand its importance in malignant progression of disease. Cytologically diagnosed dysplasias, which were employed for DNA ploidy studies, 39 mild, 28 moderate, and 11 severe dysplasia cases were found to be aneuploidy. Out of the 69 control subjects, 6 cases showed aneuploidy pattern and the rest 63 subjects were diploid. An aneuploidy pattern was observed in 8 out of 57 cases of cytologically evaluated ASCUS. The results of the followup studies showed that aberrant DNA content reliably predicts the occurrence of squamous cell carcinoma in cervical smear. Flow cytometric analysis of DNA ploidy may provide a strategic diagnostic tool for early detection of carcinoma cervix. Therefore, it is a concept of an HPV screening with reflex cytology in combination with DNA flow cytometry to detect progressive lesions with the greatest possible sensitivity and specificity.

  18. A novel functional site of extracellular matrix metalloproteinase inducer (EMMPRIN) that limits the migration of human uterine cervical carcinoma cells.

    EMMPRIN (extracellular matrix metalloproteinase inducer)/CD147, a membrane-bound glycoprotein with two extracellular loop domains (termed loops I and II), progresses tumor invasion and metastasis by increasing the production of matrix metalloproteinase (MMP) in peritumoral stoma cells. EMMPRIN has also been associated with the control of migration activity in some tumor cells, but little is known about how EMMPRIN regulates tumor cell migration. In the present study, EMMPRIN siRNA suppressed the gene expression and production of EMMPRIN in human uterine cervical carcinoma SKG-II cells. An in vitro scratch wound assay showed enhancement of migration of EMMPRIN-knockdown SKG-II cells. In addition, the SKG-II cell migration was augmented by adding an E. coli-expressed human EMMPRIN mutant with two extracellular loop domains (eEMP-I/II), which bound to the cell surface of SKG-II cells. However, eEMP-I/II suppressed the native EMMPRIN-mediated augmentation of proMMP-1/procollagenase-1 production in a co-culture of the SKG-II cells and human uterine cervical fibroblasts, indicating that the augmentation of SKG-II cell migration resulted from the interference of native EMMPRIN functions by eEMP-I/II on the cell surface. Furthermore, a systematic peptide screening method using nine synthetic EMMPRIN peptides coding the loop I and II domains (termed EM1-9) revealed that EM9 (170HIENLNMEADPGQYR184) facilitated SKG-II cell migration. Moreover, SKG-II cell migration was enhanced by administration of an antibody against EM9, but not EM1 which is a crucial site for the MMP inducible activity of EMMPRIN. Therefore, these results provide novel evidence that EMMPRIN on the cell surface limits the cell migration of human uterine cervical carcinoma cells through 170HIENLNMEADPGQYR184 in the loop II domain. Finally, these results should provide an increased understanding of the functions of EMMPRIN in malignant cervical carcinoma cells, and could contribute to the development of

    Background: The p53 protein is involved in the regulation of initiation of apoptosis. In vitro, p53-deficient cells do not respond to hypoxia with apoptosis as do p53-normal cells, and this may lead to a relative growth advantage of cells without a functioning p53 under hypoxia. On the basis of this hypothesis, a selection of cells with a functionally inactive p53 may occur in hypoxic tumors. The development of uterine cervical carcinomas is closely associated with infections of human papilloma viruses, which may cause a degradation of the tumor suppressor gene p53, resulting in a restriction of apoptosis. Thus, cervical cancers have often a functionally inactive p53. The purpose of our clinical study was therefore to investigate the association between p53, hypoxia, and prognosis in cervical cancers in which the oxygenation status can be determined by clinical methods. Material and Methods: Seventy patients with locally advanced squamous cell cervical cancer Stages IIB (n=14), IIIB (n=49), and IVA (n=7) were investigated in the period from 1996 through 1999. All were treated with definitive radiotherapy with curative intent by a combination of external radiotherapy plus high-dose-rate afterloading. Before therapy, tumor oxygenation was measured with a needle probe polarographically using the Eppendorf histograph. Hypoxic tumors were defined as those with pO 2 measurements below 5 mm Hg (HF5). Pretreatment biopsies were taken and analyzed immunohistologically for p53 protein expression with the DO-7 antibody. The DNA index was measured by flow cytometry. The statistical data analysis was done with SPSS 9.0 for Windows. Results: The 3-year overall survival was 55% for the whole group of patients. Clinical prognostic factors in a multivariate analysis were pretreatment hemoglobin level (3-year survival 62% for patients with a pretreatment hemoglobin ≥11 g/dl vs. 27% for hemoglobin <11 g/dl, p=0.006) and FIGO stage (Stage IIB: 65%; Stage IIIB: 60%; Stage IVA: 29%, p

    Aberrant activation of the Wnt/β-catenin signaling pathway is common in human cervical cancers and has great potential therapeutic value. We show that tigecycline, a FDA-approved antibiotic drug, targets cervical squamous cell carcinoma through inhibiting Wnt/β-catenin signaling pathway. Tigecycline is effective in inducing apoptosis, inhibiting proliferation and anchorage-independent colony formation of Hela cells. The inhibitory effects of tigecycline are further enhanced upon combination with paclitaxel, a most commonly used chemotherapeutic drug for cervical cancer. In a cervical xenograft model, tigecycline inhibits tumor growth as a single agent and its combination with paclitaxel significantly inhibits more tumor growth throughout the duration of treatment. We further show that tigecycline decreases level of both cytoplasmic and nuclear β-catenin and suppressed Wnt/β-catenin-mediated transcription through increasing levels of Axin 1 in Hela cells. In addition, stabilization or overexpression of β-catenin using pharmacological and genetic approaches abolished the effects of tigecycline in inhibiting proliferation and inducing apoptosis of Hela cells. Our study suggests that tigecycline is a useful addition to the treatment armamentarium for cervical cancer and targeting Wnt/β-catenin represents a potential therapeutic strategy in cervical cancer. - Highlights: • We repurposed the antibiotic drug tigecycline for cervical cancer treatment. • Tigecycline is effectively against cervical cancer cells in vitro and in vivo. • Combination of tigecycline and paclitaxel is synergistic in targeting Hela cells. • Tigecycline acts on Hela cells through inhibiting Wnt/β-catenin signaling.

    To evaluate the cephalometric changes in skeletal, dentoalveolar and soft tissue variables induced by Clark's Twin Block (CTB) in Class II, Division 1 malocclusion patients and to compare these changes in different cervical vertebral maturation stages. Pre- and post-treatment/observation lateral cephalograms of 53 Class II, Division 1 malocclusion patients and 60 controls were compared to evaluate skeletal, dentoalveolar and soft tissue changes. Skeletal maturity was assessed according to cervical vertebral maturation stages. Pre- and post-treatment/observation mean changes and differences (T2-T1) were compared by means of Wilcoxon sign rank and Mann-Whitney U-tests, respectively. Intergroup comparisons between different cervical stages were performed by means of Kruskal-Wallis test and Mann-Whitney U-test (p ≤ 0.05) . When compared with controls, there was a significant reduction in ANB angle (p cervical stages (p cervical stages (p cervical stages, significant differences were found for SNA, SNB and UI-SN angles and overjet. . The Twin-Block along with the normal craniofacial growth improves facial esthetics in Class II, Division 1 malocclusion by changes in underlying skeletal and dentoalveolar structures. The favorable mandibular growth occurs during any of the cervical vertebral maturation stages, with more pronounced effect during CS-3 stage.

    We investigated the efficacy of concurrent chemoradiotherapy (CCRT) over radiotherapy (RT) in Chinese patients with locally advanced cervical carcinoma. Between January 2005 and January 2008, 192 patients with squamous cell carcinoma of the cervix were included in the study: 96 in arm A (CCRT with 20 mg/m 2 cisplatin for 5 days) and 96 in arm B (RT). The overall response rate was the primary endpoint. The secondary endpoints included overall survival, progression-free survival, and toxicity. The 5-year overall response rate was 67% and 53% for the CCRT and RT arms, respectively, and the difference was statistically significant, while the median overall survival was 68 months (range 3-85 months) and 61 months (range 4-83 months), respectively (P = 0.009). In addition, the median progression-free survival for CCRT was 62 months (range 3-83 months), whereas it was 51 months (range 4-81 months) for the RT arm (P = 0.025). The toxicity profile, both acute and late, was comparable in both arms. In summary, we demonstrate that CCRT was effective and better tolerated than RT alone in Chinese patients with locally advanced cervical carcinoma.

    Introduction: Cervical cancer in women occupies 3rd place in incidence and 5th as a cause of cancer death in our country. The evolution is mainly determined by the stage, nodal status and histological type. The treatment of these tumors is surgical, radiant and / or systemic, depending on your choice mainly Stadium. Objective: To analyze the characteristics, evolution, treatment and survival of patients carriers of cervical cancer. Patients and Methods: The medical records were retrospectively analyzed for patients with cervical cancer treated at the Department of Oncology the Clinical Hospital in the period 1994-2004. Curves were constructed survival (sv) of total and free enfemedad sv sv by stage and after relapse by the method of Kaplan-Meier. Results: n = 75 patients, median age 45 years (24-90 years). Histological type: Epidermoid carcinomas 93% 5% 2% adenocarcinomas and adenosquamous. stadium (E) Initial: 31% IE, 38% EII, EIII 25%, 6% EIVA. Treatment was according to the stadium, considering that until 1999 was not standard concurrent chemoradiation. The median sv considering all stages was 124 months. The sv to 5 years for EI was 90% (median 188 sv months), for the ISI 65% (95 months) and the median sv CIRTs was 24 months. Followed for 13 months, 12 patients relapsed and the median after sv relapse was 8 months (95% CI 4-13 months) Conclusions: Although cervical cancer is a preventable disease, remains an important cause of morbidity and mortality. Our results are consistent with those reported in the literature, however far from the optimal, so it is necessary to continue clinical trials in this regard

    Histopathology is a cornerstone in the diagnosis of cervical cancer but the prognostic value is controversial. Women under active follow-up for histologically confirmed primary invasive cervical cancer were selected from the United States Surveillance, Epidemiology, and End Results (SEER) 9-registries public use data 1973–2002. Only histologies with at least 100 cases were retained. Registry area, age, marital status, race, year of diagnosis, tumor histology, grade, stage, tumor size, number of positive nodes, number of examined nodes, odds of nodal involvement, extent of surgery, and radiotherapy were evaluated in Cox models by stepwise selection using the Akaike Information Criteria. There were 30,989 records evaluable. From 1973 to 2002, number of cases dropped from 1,100 new cases/year to 900/year, but adenocarcinomas and adenosquamous carcinoma increased from 100/year to 235/year. Median age was 48 years. Statistically significant variables for both overall and cause-specific mortality were: age, year of diagnosis, race, stage, histology, grade, hysterectomy, radiotherapy, tumor size and nodal ratio. The histological types were jointly significant, P < 0.001. Cause-specific mortality hazard ratios by histological type relatively to non-microinvasive squamous cell carcinoma were: microinvasive squamous cell carcinoma 0.28 (95% confidence interval: 0.20–0.39), carcinoma not otherwise specified 0.91 (0.79–1.04), non-mucinous adenocarcinoma 1.06 (0.98–1.15), adenosquamous carcinoma 1.35 (1.20–1.51), mucinous adenocarcinoma 1.52 (1.23–1.88), small cell carcinoma 1.94 (1.58–2.39). Small cell carcinoma and adenocarcinomas were associated with poorer survival. The incidental observation of increasing numbers of adenocarcinomas despite a general decline suggests the inefficiency of conventional screening for these tumors. Increased incidence of adenocarcinomas, their adverse prognosis, and the young age at diagnosis indicate the need to identify women who

    Normal human foreskin keratinocytes cotransfected with the neomycin resistance gene and recombinant human papillomavirus (HPV) DNAs (types 16, 18, 31, and 33) that have a high or moderate association with cervical malignancy acquired immortality and contained integrated and transcriptionally active viral genomes. Only transcripts from the intact E6 and E7 genes were detected in at least one cell line, suggesting that one or both of these genes are responsible for immortalization. Recombinant HPV DNAs with low or no oncogenic potential for cervical cancer (HPV1a, -5, -6b, and -11) induced small G418-resistant colonies that senesced as did the nontransfected cells. These colonies contained only episomal virus DNA; therefore, integration of HPV sequences is important for immortalization of keratinocytes. This study suggests that the virus-encoded immortalization function contributes to the pathogenesis of cervical carcinoma.

    Full Text Available OBJECTIVE: The aim of this cross sectional study was to assess serum insulin-like growth factor-1 (IGF-1 levels in female and male subjects at various cervical vertebral maturation (CVM stages. MATERIAL AND METHODS: The study sample consisted of 60 subjects, 30 females and 30 males, in the age range of 8-23 years. For all subjects, serum IGF-1 level was estimated from blood samples by means of chemiluminescence immunoassay (CLIA. CVM was assessed on lateral cephalograms using the method described by Baccetti. Serum IGF-1 level and cervical staging data of 30 female subjects were included and taken from records of a previous study. Data were analyzed by Kruska-Wallis and Mann Whitney test. Bonferroni correction was carried out and alpha value was set at 0.003. RESULTS: Peak value of serum IGF-1 was observed in cervical stages CS3 in females and CS4 in males. Differences between males and females were observed in mean values of IGF-1 at stages CS3, 4 and 5. The highest mean IGF-1 levels in males was observed in CS4 followed by CS5 and third highest in CS3; whereas in females the highest mean IGF-1 levelswas observed in CS3 followed by CS4 and third highest in CS5. Trends of IGF-1 in relation to the cervical stages also differed between males and females. The greatest mean serum IGF-1 value for both sexes was comparable, for females (397 ng/ml values were slightly higher than in males (394.8 ng/ml. CONCLUSIONS: Males and females showed differences in IGF-1 trends and levels at different cervical stages.

    Critical assessment of head and neck cancer with respect to staging has, on occasion, been disappointingly ineffective. We have attempted to correlate the incidence of measureable uptake of cobalt 57 tagged bleomycin by primary squamous cell carcinoma and metastatic cervical lymph nodes. Forty-six cases have been evaluated with respect to histopathological confirmation of the suspected metastatic disease. We have found that this diagnostic measure increases our acumen in staging of head and neck cancer. The relevance of the Co-Bleo scans as a diagnostic aid is reported in 46 cases. Malignant tumors greater than 2 cm in size appear to demonstrate active uptake of the imaging agent. Small tumor size and excess background radioactivity contribute to the false-negatives (17%). Inflammatory conditions or benign tumors of the salivary apparatus may result in minimal uptake, thus, a false-positive result (10%). An increase in the radioactivity of the Co-Bleo may enhance the benefits of this procedure in the search for an undiagnosed primary, as well as undiagnosed local or distant metastases

    To assess the combined effectiveness of angioinfarction and immunotherapy for improving survival in patients with stage IV renal cell carcinoma. During the past 3 years, 13 patients of stage IV renal cell carcinoma were treated with angioinfarction and immunotherapy. Angioinfarction was performed on these 13 patients using absolute ethanol and occlusive balloon catheter. After angioinfarction, Interferon alpha was used for immunotherapy. For our analysis, 12 control patients of stage IV renal cell carcinoma without treatment were included in the study. Survival has been calculated according to the Kaplan and Meier method. The 1 year survival rate and median survival time in patients treated with angioinfarction and immunotherapy, were 46% and 13 months and in patients without treatment, 16% and 4 months, respectively. The combined treatment of angioinfarction and immunotherapy is of considerable value for improving survival in patients with stage IV renal cell carcinoma

    Objective: To investigate cytotoxic and radiosensitizing effect of Artemisinin on cervical carcinoma cell line HeLa. Methods: In order to measure the optimized effective time, cytotoxic effect of Artemisinin on HeLa cell line was investigated with MTT assay. The radiosensitization effect of different doses and different treatment duration of Artemisinin on HeLa cell line were evaluated by MTT test, the SER is 1.17 and radiosensitizing effect was measured with multi-target single hit model through SER of HeLa cell. Cell cycles in different groups were calculated by flow cytometry. Results: The 50% inhibition concentration of Artemisinin interacted with HeLa cells for 24 h is 600.19 nmol/ml, and for 48 h is 160.71 nmol/ml. The HeLa cells'surival ratio is 93.51%, 91.87%, and 87.28% after adding Atemisinin of 110.69 nmol/ml and 1 Gy radiation exposure. There are three groups: the chemotherapy only group, the radiotherapy only group and the combination group. The result of the cell cycles showed that cells in G 2 /M period decreased in the combination group. Conclusion: Artemisinin has radiosensitization effect on cervical carcinoma HeLa cells, whichshows dose and time dependent. Artemisinin can inhibit the G 2 /M block by ionizing radiation. (authors)

    To explore the differentially expressed proteins in normal cervix, cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) tissues by differential proteomics technique. Cervical tissues (including normal cervix, CIN and CSCC) were collected in Department of Gynecologic Oncology of Beijing Obstetrics and Gynecology Hospital. Two-dimensional fluorescence difference in gel electrophoresis (2-D DIGE) and DeCyder software were used to detect the differentially expressed proteins. Matrix-assisted laser desorption/ionization-time-of-flight tandem mass spectrometry (MALDI-TOF/TOF MS) was used to identify the differentially expressed proteins. Western blot (WB) and immunohistochemistry (IHC) were performed to validate the expressions of selected proteins among normal cervix, CIN and CSCC. 2-D DIGE images with high resolution and good repeatability were obtained. Forty-six differentially expressed proteins (27 up-regulated and 19 down-regulated) were differentially expressed among the normal cervix, CIN and CSCC. 26 proteins were successfully identified by MALDI-TOF/TOF MS. S100A9 (S100 calcium-binding protein A9) was the most significantly up-regulated protein. Eukaryotic elongation factor 1-alpha-1 (eEF1A1) was the most significantly down-regulated protein. Pyruvate kinase isozymes M2 (PKM2) was both up-regulated and down-regulated. The results of WB showed that with the increase in the severity of cervical lesions, the expression of S100A9 protein was significantly increased among the three groups (P = 0.010). The expression of eEF1A1 was reduced but without significant difference (P = 0.861). The expression of PKM2 was significantly reduced (P = 0.000). IHC showed that protein S100A9 was mainly expressed in the cytoplasm, and its positive expression rate was 20.0 % in normal cervix, 70.0 % in CIN and 100.0 % in CSCC, with a significant difference among them (P = 0.006). eEF1A1 was mainly expressed in the cell plasma, and its

    During 1969-1975, 212 new patients with Stage I nasopharyngeal carcinoma (NPC) with a tumor apparently confined to the nasopharynx were treated at Queen Elizabeth Hospital, Kowloon, Hong Kong. The initial histologies of 137 patients were available for review and further studies. The primary tumors were histologically classified into two major types - squamous cell carcinoma (35 patients) and undifferentiated carcinoma (102 patients). The latter was further divided into 4 sub-types: lymphoepithelioma of the Schmincke type, lymphoepithelioma of the Regaud type, spindle cell carcinoma, and undifferentiated carcinoma of the nasopharyngeal type. Such histological typing of the initial tumor was not of value in predicting the clinical outcome, whether in terms of 5-year crude or disease-free survival rate, or the tendency of the tumor to develop recurrence at the primary site, or distance metastases after a standardized course of radiation therapy. There is not significant correlation between the extent of mononuclear infiltration nor fibrosis in the tumor stroma and the survival or tumor control rates

    Full Text Available Introduction: Dosimetric study to compare high dose rate (HDR vaginal vault ovoid brachytherapy plan versus intensity-modulated radiation therapy (IMRT boost plan for doses delivered to target volume and organs at risk (OAR in postoperative patients of cervical carcinoma following whole pelvic radiotherapy (WPRT. Materials and Methods: Fifteen postoperative patients of cervical carcinoma suitable for vaginal ovoid brachytherapy following WPRT of 46 Gy/23 fractions/4.5 weeks were included. All were treated with brachytherapy (two sessions of 8.5 Gy each. The equivalent dose for IMRT was calculated by computing biologically effective dose of brachytherapy by linear quadratic model. Dose of brachytherapy (two sessions of 8.5 Gy was equivalent to IMRT dose of 26 Gy/13 fractions. Doses to target volume and OAR were compared between HDR and IMRT plans. Results: Target volume was well covered with both HDR and IMRT plans, but dose with brachytherapy was much higher (P < 0.05. Mean doses, doses to 0.1, 1, 2, and 5cc, 1/3 rd , 1/2, and 2/3 rd volume of bladder and rectum were significantly lower with HDR plans. Conclusion: In postoperative patients of cervical carcinoma, HDR brachytherapy following WPRT appears to be better than IMRT for tumor coverage and reducing dose to critical organs.

    The study included 26 patients with FIGO stage Ia1–Ib1 cervical cancer who underwent fertility-sparing surgery (transabdominaltrachelectomy). To visualize sentinel lymph nodes, lymphoscintigraphy with injection of 99mTc-labelled nanocolloid was performed the day before surgery. Intraoperative identification of sentinel lymph nodes using hand-held gamma probe was carried out to determine the radioactive counts over the draining lymph node basin. The sentinel lymph node detection in cervical cancer patients contributes to the accurate clinical assessment of the pelvic lymph node status, precise staging of the disease and tailoring of surgical treatment to individual patient.

    Cervical carcinoma is the second most common gynaecological cancer worldwide. Despite substantial advances in screening the pre-invasive forms, the management of women suffering from invasive cervical carcinomas remains problematic. In pre-treatment staging, the evaluation of the loco-regional and distant extent of the disease, according to the international federation of gynecology and obstetrics, has shown to be sub-optimal. After treatment, the routine surveillance protocol, based on a physical examination at the control visits and clinically oriented conventional imaging procedures, most often fails to accurately detect a recurrent disease. Its sensitivity is particularly low for asymptomatic women. On the other hand, the clinical value of positron emission tomography using 18 F-fluorodeoxyglucose in the field of oncology is nowadays firmly established. In many tumour types, including the gynaecological cancers such as breast cancer and ovarian cancer, the metabolic imaging has proved to play a determinant role in both the pre-treatment and post-treatment evaluation. In the present review-article, we analyse in the light of the literature data and our experience, the potential contribution of positron emission tomography using 18 F-fluorodeoxyglucose in the management of cervical cancer.

    Purpose: Because a combination of retinoic acid, interferon-alpha, and radiation therapy demonstrated synergistic action and effectiveness to treat advanced cervical cancers in earlier studies, we designed this randomized phase 2 open-label trial to assess efficacy and safety of interferon alpha-2b (IFN) and 13-cis-retinoic acid (RA) administered concomitantly with radiation therapy (IFN-RA-radiation) to treat stage III cervical cancer. Methods and Materials: Stage III cervical cancer patients were randomized to study and control groups in a 1:1 ratio. All patients were treated with radiation therapy; study arm patients received IFN (3 × 10{sup 6} IU subcutaneously) 3 times a week for 4 weeks and daily RA (40 mg orally) for 30 days starting on day 1 of radiation, whereas control arm patients received weekly cisplatinum (40 mg/m{sup 2}) for 5 weeks during radiation. Patients were followed for 3 years. The primary endpoint was overall survival at 3 years. Results: Patients in the study (n=104) and control (n=105) groups were comparable for clinicopathological characteristics, radiation therapy–related variables and treatment response. Proportions of disease-free patients in the study and control groups were 38.5% and 44.8%, respectively, after median follow-up of 29.2 months. Hazard ratios were 0.67 (95% confidence interval [CI]: 0.44-1.01) and 0.69 (95% CI: 0.44-1.06) for overall and disease-fee survival, respectively, comparing the study group to control, and demonstrated an inferior outcome with RA-IFN-radiation, although differences were statistically nonsignificant. Kaplan-Meier curves of disease-free and overall survival probabilities also showed inferior survival in the study group compared to those in the control. Acute toxicities of chemoradiation were significantly higher with 2 acute toxicity-related deaths. Conclusions: Treatment with RA-IFN-radiation did not demonstrate survival advantage over chemoradiation despite being less toxic. The

    Radiation-induced bowel damage occurred in 4.3% of patients treated primarily by irradiation for uterine carcinoma during the period 1962-1982. There has been a progressive rise in the incidence of radiation damage and radiation-induced rectovaginal fistula during this 20-year period. Radiation from intracavitary sources was a contributory factor in 92% of injured cases. The rising incidence of bowel damage in our patients may be due to an increase in the number of patients receiving a high rectal dose from the intracavitary source. There was a significantly (P<0.01) higher incidence of radiation injury in cases of cervical carcinoma compared to endometrical carcinoma. This was because cervical carcinoma tended to present at a more advanced stage than endometrial carcinoma and was more frequently treated with combined external and intracavitary irradiation. There was no significant increase in the incidence of complications among patients undergoing hysterectomy. (author)

    Eighteen patients with renal neoplasm underwent magnetic resonance imaging (MRI) using a 1.5 Tesla superconducting magnetic system and spin echo images were obtained by quick scan technique under holding breath. MR images were interpreted independently of the computerized tomography (CT) findings. The preoperative stagings of the 18 renal carcinomas, as judged by MRI, were compared with those obtained at laparotomy. The anatomic staging was correctly performed by MRI in 13 patients (72 %). In the patients who had intrarenal small tumor with normal renal contour, MRI demonstrated a solid mass clearly distinguishable from surrounding renal parenchyma using the paramagnetic contrast agent (gadolinium-DTPA). When compared with results of evaluation by CT in staging, MRI appeared to have several advantages in determination of whole mass; the detection of tumor thrombus into renal vein and inferior vena cava; and the evaluation of direct tumor invasion of adjacent organs. MRI should play an important role in the staging of renal cell carcinoma.

    To present our experience of staged correction with multiple cervical hemivertebra resection and thoracic pedicle subtraction osteotomy (PSO) treating a rare and complicated congenital scoliosis. A 14-year-old male presented with progressive torticollis and spine deformity. The malformation developed since birth, and back pain after long-time sitting or exercise arose since 6 months before, which was unsuccessfully treated by physiotherapy. X-ray showed a right cervical curve of 60° and a left compensatory thoracic curve of 90°. Three-dimensional computed tomography (3-D CT) scan revealed three semi-segmented hemivertebrae (C4, C5 and C6) on the right side. Based on our staged strategy, the three consecutive cervical hemivertebrae, as the major pathology causing the deformity, were firstly resected by the combined posterior and anterior approach. Six months later, T6 PSO osteotomy was used to correct the structural compensatory thoracic curve. The cervical curve was reduced to 23° while the thoracic curve to 60° after the first-stage surgery, and the thoracic curve was further reduced to 30° after the second-stage surgery. The radiograph at 5-year follow-up showed that both the coronal and sagittal balance were well restored and stabilized, with the occipital tilt reduced from 12° to 0°. Our strategy may provide an option for similar cases with multiple consecutive cervical hemivertebrae and a large structural compensatory thoracic curve, which proved to achieve excellent correction in both the coronal and sagittal planes with acceptable neurologic risk.

    Purpose/Objective(s): To investigate the factors contributing to the clinical presentation of oropharyngeal squamous cell carcinoma (OPSCC) in the era of risk stratification using human papilloma virus (HPV) and smoking status. Methods and Materials: All patients with OPSCC presenting to our institutional multidisciplinary clinic from January 2009 to June 2015 were reviewed from a prospective database. The patients were grouped as being at low risk, intermediate risk, and high risk in the manner described by Ang et al. Variance in clinical presentation was examined using χ{sup 2}, Kruskal-Wallis, Mann-Whitney, and logistic regression analyses. Results: The rates of HPV/p16 positivity (P<.001), never-smoking (P=.016), and cervical lymph node metastases (P=.023) were significantly higher for patients with OPSCC of the tonsil, base of tongue (BOT), or vallecula subsites when compared with pharyngeal wall or palate subsites. Low-risk patients with tonsil, base of tongue, or vallecula primary tumors presented with nodal stage N2a at a much higher than expected frequency (P=.007), and high-risk patients presented with tumor stage T4 at a much higher than expected frequency (P=.003). Patients with BOT primary tumors who were never-smokers were less likely to have clinically involved ipsilateral neck disease than were former smokers (odds ratio 1.8; P=.038). The distribution of cervical lymph node metastases was not associated with HPV/p16 positivity, risk group, or subsite. When these data were compared with those in historical series, no significant differences were seen in the patterns of cervical lymph node metastases for patients with OPSCC. Conclusions: For patients with OPSCC differences in HPV status, smoking history and anatomic subsite were associated with differences in clinical presentation but not with distribution of cervical lymph node metastases. Historical series describing the patterns of cervical lymph node metastases in patients with OPSCC remain

    To describe the sociodemographic characteristics and clinical profile of women presenting with cervical carcinoma and to identify factors associated with the timing of presentation and prognosis. A record-based descriptive study was carried out from 1 st February to 31 st March 2014 at Tertiary Care Hospitals of Mangalore. The study population included women who were diagnosed with cervical carcinoma from January 1, 2010 to December 31, 2013. A pretested data extraction sheet aimed at collecting information from the inpatient records was used as the study instrument. The collected data were entered and analyzed using SPSS version 16.0. A total of 227 patients were included in the study. Mean (Standard Deviation) age of diagnosis of cervical cancer was found to be 55 ± 11 years. Majority of the women were Hindus (88.5%) and 51.0% of the women had occupational activities out of which manual labor was the most common. Forty-eight percent of the patients presented in the late stages. Squamous cell carcinoma was found to be the most common histological type. It was also observed that a slightly higher proportion of women with an age >49 years presented in late stages of the disease ( n = 70, 48.6%) compared to women <49 years of age ( n = 28, 46.7%); however, the difference was not statistically significant ( P = 0.800). Our study found out a higher proportion of late presentation by the patients. It emphasizes the need for the development and implementation of an efficient screening cum prevention program for cervical cancer and to continue active research in the domains of identifying all possible risk factors and steps to mitigate them.

    The rat parvovirus H-1PV has oncolytic and tumour-suppressive properties potentially exploitable in cancer therapy. This possibility is being explored and results are encouraging, but it is necessary to improve the oncotoxicity of the virus. Here we show that this can be achieved by co-treating cancer cells with H-1PV and histone deacetylase inhibitors (HDACIs) such as valproic acid (VPA). We demonstrate that these agents act synergistically to kill a range of human cervical carcinoma and pancreatic carcinoma cell lines by inducing oxidative stress, DNA damage and apoptosis. Strikingly, in rat and mouse xenograft models, H-1PV/VPA co-treatment strongly inhibits tumour growth promoting complete tumour remission in all co-treated animals. At the molecular level, we found acetylation of the parvovirus nonstructural protein NS1 at residues K85 and K257 to modulate NS1-mediated transcription and cytotoxicity, both of which are enhanced by VPA treatment. These results warrant clinical evaluation of H-1PV/VPA co-treatment against cervical and pancreatic ductal carcinomas. © 2013 The Authors. Published by John Wiley and Sons, Ltd on behalf of EMBO.

    In our center limited centro pelvic invasive carcinomas of the uterine cervix (less than 4 cm) are treated with brachytherapy and surgery. With these therapeutic modalities no residual carcinoma was observed for 80% of the patients. The purpose of this study was to evaluate our results with this treatment, and to evaluate the prognostic value of the pathological status of the cervix. From 1976 to 1987 we have treated 115 patients with these modalities. Staging system used was the FIGO classification modified for Stage II (divided in early Stage II and late Stage II). Patients were Stage IB (70 cases) and early Stage II (45 cases); 60 Gy were delivered with utero vaginal brachytherapy before any treatment. Six weeks later a radical hysterectomy with pelvic lymphadenectomy was performed. Twenty-one patients with positive nodes received a pelvic radiotherapy (45 to 55 Gy). Local control rate was 97% (100% for Stage IB and 93% for early Stage II). Uncorrected 10-year actuarial survival rate was 96% for Stage IB and 80% for early Stage II patients. No treatment failure was observed for Stage IB patients. Ninety-two patients (80%) had no residual carcinoma in the cervix (group 1) and 23 patients (20%) had a residual tumor (group 2). The sterilization rate of the cervix was 87% for Stage IB tumors versus 69% for early Stage II, and was 82% for N- patients versus 68% for N+ patients. Ten year actuarial survival rate was 92% for group 1 and 78% for group 2 (p = 0, 1). Grade 3 complications rate was 6%. We conclude that brachytherapy + surgery is a safe treatment for limited centro pelvic carcinomas of the uterine cervix (especially Stage IB) and that pathological status of the cervix after brachytherapy is not a prognostic factor

    We prospectively compared PET/CT and conventional imaging for initial staging of nasopharyngeal carcinoma (NPC). A total of 111 patients with histologically proven NPC were investigated with PET/CT and conventional imaging (head-and-neck MRI, chest X-ray, abdominal ultrasound, and bone scan) before treatment. The respective findings were reviewed independently and then compared with each other. With regard to T staging, PET/CT showed a discrepancy with head-and-neck MRI in 36 (32.4%) of the study subjects. With regard to N staging, PET/CT showed a discrepancy with head-and-neck MRI in 15 (13.5%) patients. Among the discordant cases, MRI was superior in demonstrating tumor involvement in the parapharyngeal space, skull base, intracranial area, sphenoid sinus, and retropharyngeal nodes while PET/CT was superior in demonstrating neck nodal metastasis. PET/CT disclosed 13 of 16 patients with distant malignancy compared with four patients disclosed by conventional imaging work-up. The false-positive rate of PET/CT was 18.8%. PET/CT correctly modified M staging in eight patients (7.2%) and disclosed a second primary lung malignancy in one patient (0.9%). In NPC patients, MRI appears to be superior to PET/CT for the assessment of locoregional invasion and retropharyngeal nodal metastasis. PET/CT is more accurate than MRI for determining cervical nodal metastasis and should be the better reference for the neck status. PET/CT has an acceptable diagnostic yield and a low false-positive rate for the detection of distant malignancy and can replace conventional work-up to this aim. PET/CT and head-and-neck MRI are suggested for the initial staging of NPC patients. (orig.)

    Using MR imaging with a body coil parametrial invasion was determined prospectively in 169 consecutive patients considered on the basis of clinical examination to have carcinoma confined to the cervix. After radical hysterectomy correlation with histologic examination was performed for the left and right parametrium separately. The criterion for parametrial invasion was a high-signal-intensity lesion with disruption of the full thickness of the cervical stroma combined with areas of abnormal signal intensity within the parametrial region on T2-weighted images. Histologic examination showed that 18 parametria in 13 patients were invaded by tumor. MR had an overall accuracy of 93%, a sensitivity of 89%, and a specificity of 93% in demonstrating parametrial involvement. Positive and negative predictive values were 43% and 99%. The main weakness of MR was 21 false-positive tests. This represents a limitation when MR is performed with a body coil. (orig.)

    Purpose: Worldwide, particularly in developing countries, many women present with advanced stage cervical cancer for which palliative radiotherapy is the treatment of choice or may be the only available treatment. The purpose of this study was to determine from the literature the optimal palliative radiation scheme for the treatment of advanced cervical cancer. Design: A systematic literature review up to January 2010 was performed in Medline, Embase, the Cochrane database, CinHL and Google Scholar using a combination of synonyms for: cervical cancer, palliative treatment and radiation therapy. No limitations were applied for language or study types. For included papers data were extracted and described. Results: Only eight papers were identified and none compared the results of different fractionation schemes. Most used observational retrospective study design with considerable sources of bias. No studies used validated endpoints for symptom relief nor did they include measures of the quality of life. Several papers described the experience with single or multiple monthly 10 Gy doses or with a higher total dose delivered in 2-4 fractions within 48 h to 1 week. Studies report varying amounts of relief from bleeding. The effect on other symptoms such as pain and discharge is not evaluable. Acute and late toxicity is poorly documented. Conclusion: There is a dearth of information in the current literature to guide selection of an optimal palliative radiation schedule for treatment of patients with advanced cervical cancer. Based on this review and information from other solid tumors, there is no evidence to support the common belief that better and longer palliation is achieved with a high dose delivered in multiple smaller fractions. There is a clear need for comparative studies of different radiation fractionation schedules in order to identify an optimal palliative radiation scheme. These studies require the use of validated endpoints to measure specific symptom

  16. Applicability of preoperative nuclear morphometry to evaluating risk for cervical lymph node metastasis in oral squamous cell carcinoma.

    Masaaki Karino

    Full Text Available BACKGROUND: We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study, we evaluated the applicability of this morphometric technique to evaluating the risk for cervical lymph node metastasis in oral squamous cell carcinoma. METHODS: A digital image system was used to measure the mean nuclear area, mean nuclear perimeter, nuclear circular rate, ratio of nuclear length to width (aspect ratio, and nuclear area coefficient of variation (NACV. Relationships between these parameters and nodal status were evaluated by t-test and logistic regression analysis. RESULTS: Eighty-eight cases of squamous cell carcinoma (52 of the tongue, 25 of the gingiva, 4 of the buccal mucosa, and 7 of the mouth floor were included: 46 with positive node classification and 42 with negative node classification. Nuclear area and perimeter were significantly larger in node-positive cases than in node-negative cases; however, there were no significant differences in circular rate, aspect ratio, or NACV. We derived two risk models based on the results of multivariate analysis: Model 1, which identified age and mean nuclear area and Model 2, which identified age and mean nuclear perimeter. It should be noted that primary tumor site was not associated the pN-positive status. There were no significant differences in pathological nodal status by aspect ratio, NACV, or primary tumor site. CONCLUSION: Our method of preoperative nuclear morphometry may contribute valuable information to evaluations of the risk for lymph node metastasis in oral squamous cell carcinoma.

    The purpose of this study was to evaluate the prognosis of breast carcinoma by comparison with X-ray mammographic findings, nuclear and histologic grade, and TNM staging. We retrospectively reviewed 114 cases (113 patients) of breast carcinoma, analysing X-ray mammographic findings of all cases with regard to mass, calcification, and spiculation. In 80 cases of scirrhous invasive ductal breast carcinoma. Black's nuclear and Bloom-Richardson's histologic grade were also evaluated. Mammographic findings and nuclear and histologic grade were compared with TNM staging which might suggest the prognosis of breast carcinoma. X-ray mammographic findings (mass, calcification and spiculation) did not significantly correlate with T staging, but the clinical staging of the spiculation was advanced. These X-ray findings did not significantly correlate with the nuclear grading and the histologic grading. Nuclear grade did not correlate with T and M staging, but correlated significantly with N staging and clinical stage(p < 0.05). Histologic grade did not significantly correlate with TNM staging. The clinical staging of spiculation was advanced and nuclear grade correlated significantly with N stage and clinical staging. X-ray mammographic findings did not directly correlate with nuclear and histologic grading, but combined studies of the evaluation of mammographic findings and nuclear and histologic grade were useful for prognosing breast carcinoma

    While FDG PET/CT for the evaluation of nasopharyngeal carcinoma (NPC) in adult patients has documented advantages and disadvantages compared with conventional imaging, to our knowledge, no studies of FDG PET/CT for the evaluation of NPC in pediatric patients have been performed. In this investigation, we studied the utility of FDG PET/CT in children with NPC. The study group comprised 18 children with biopsy-proven NPC who underwent FDG PET/CT and MRI (total 38 pairs of images). All baseline and follow-up FDG PET/CT and MRI studies were independently reviewed for restaging of disease. The concordance between FDG PET/CT and MRI in T, N, and overall staging was 29%, 64%, and 43%, respectively. Compared with MRI, FDG PET/CT yielded lower T and overall staging and showed less cervical and retropharyngeal lymphadenopathy. The concordance between follow-up FDG PET/CT and MRI was 79% overall and 100% 9 months after therapy. In patients who achieved complete remission, FDG PET/CT showed disease clearance 3-6 months earlier than MRI. There were no false-positive or false-negative FDG PET/CT scans during follow-up. FDG PET/CT may underestimate tumor extent and regional lymphadenopathy compared with MRI at the time of diagnosis, but it helps to detect metastases and clarify ambiguous findings. FDG PET/CT is sensitive and specific for follow-up and enables earlier determination of disease remission. FDG PET/CT is a valuable imaging modality for the evaluation and monitoring of NPC in pediatric patients. (orig.)

    Purpose: Constitutively activated signal transducers and activators of transcription (STAT) factors, in particular STAT1, STAT3, and STAT5, have been detected in a wide variety of human primary tumors and have been demonstrated to directly contribute to oncogenesis. However, the expression pattern of these STATs in cervical carcinoma is still unknown, as is whether or not they have prognostic significance. This study investigated the expression patterns of STAT1, STAT3, and STAT5 in cervical cancer and their associations with clinical outcomes in patients treated with radical radiation therapy. Methods and Materials: A total of 165 consecutive patients with International Federation of Gynecology and Obstetrics (FIGO) Stages IB to IVA cervical cancer underwent radical radiation therapy, including external beam and/or high-dose-rate brachytherapy between 1989 and 2002. Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed. Univariate and multivariate analyses were performed to identify and to evaluate the effects of these factors affecting patient survival. Results: Constitutive activations of STAT1, STAT3, and STAT5 were observed in 11%, 22%, and 61% of the participants, respectively. While STAT5 activation was associated with significantly better metastasis-free survival (p < 0.01) and overall survival (p = 0.04), STAT1 and STAT3 activation were not. Multivariate analyses showed that STAT5 activation, bulky tumor ({>=}4 cm), advanced stage (FIGO Stages III and IV), and brachytherapy (yes vs. no) were independent prognostic factors for cause-specific overall survival. None of the STATs was associated with local relapse. STAT5 activation (odds ratio = 0.29, 95% confidence interval = 0.13-0.63) and advanced stage (odds ratio = 2.54; 95% confidence interval = 1.03-6.26) were independent predictors of distant metastasis. Conclusions: This is the first report to provide the overall expression patterns and prognostic significance of

    To investigate the factors contributing to the clinical presentation of oropharyngeal squamous cell carcinoma (OPSCC) in the era of risk stratification using human papilloma virus (HPV) and smoking status. All patients with OPSCC presenting to our institutional multidisciplinary clinic from January 2009 to June 2015 were reviewed from a prospective database. The patients were grouped as being at low risk, intermediate risk, and high risk in the manner described by Ang et al. Variance in clinical presentation was examined using χ(2), Kruskal-Wallis, Mann-Whitney, and logistic regression analyses. The rates of HPV/p16 positivity (Phigh-risk patients presented with tumor stage T4 at a much higher than expected frequency (P=.003). Patients with BOT primary tumors who were never-smokers were less likely to have clinically involved ipsilateral neck disease than were former smokers (odds ratio 1.8; P=.038). The distribution of cervical lymph node metastases was not associated with HPV/p16 positivity, risk group, or subsite. When these data were compared with those in historical series, no significant differences were seen in the patterns of cervical lymph node metastases for patients with OPSCC. For patients with OPSCC differences in HPV status, smoking history and anatomic subsite were associated with differences in clinical presentation but not with distribution of cervical lymph node metastases. Historical series describing the patterns of cervical lymph node metastases in patients with OPSCC remain clinically relevant. Copyright © 2016 Elsevier Inc. All rights reserved.

    One of the major challenges of modern genetics is to apply recent advances in mutation research to improve the accuracy of the estimates of the genetic risk for humans. Because of the important implications for radiation protection, biological effects of low-dose radiation have been a focus of research in recent years. Previously we have found that human cervical carcinoma HeLa cells irradiated repeatedly with low doses of gamma rays (HeLa1500 cells) became resistant to cisplatin. In this study we examine whether this effect was caused by inhibition of apoptosis. In HeLa and HeLa1500 cells we determined the induction of apoptosis following the treatment with cisplatin (i) by counting apoptotic cells with characteristic morphological changes, (ii) by analysing the expression of apoptotic genes involved in cytochrome c/Apaf-1/caspase-9 and in Fas/FasL pathways by Western blot method, and (iii) by estimating the activities of caspases by commercial caspase detection kits. Our results show that low doses of gamma rays induced alterations in human cervical carcinoma cells that were reflected in inhibition of p53-independent cisplatin-induced apoptosis due to reduced activity of caspase 3.

    Background Borderline ovarian tumors (BOTs) are difficult to differentiate from stage I carcinoma using radiological findings. Little is known about the correlation between CA-125 levels and radiological findings for predicting BOTs or carcinoma. Purpose To assess the role of CA-125, in addition to that of radiological findings, in differentiating BOTs from stage I carcinoma. Material and Methods The study received institutional review board approval, with waiver of informed consent. We evaluated 100 patients (two groups: BOT, 58 patients; stage I carcinoma, 42 patients) using radiological findings, including location and size of each tumor, number and size of septations, papillary projections and vegetations, peritoneal implants, ascites, and preoperative CA-125 levels. The differences in CA-125 levels according to bilateral location, solid components, and thickness of septations between the two groups were evaluated using the McNemar test. Correlations of CA-125 level to size and number of septations were evaluated by the independent sample t test. Results No statistical correlation was found between CA-125 level and location, size, and number of septations between the two groups. Solid components within the tumors were similar in the two groups, but the CA-125 level was significantly higher in stage I carcinoma than in BOTs. The number of septations per tumor was similar in the two groups; thick septations were more frequent in stage I carcinoma than in BOTs, and a significantly higher titer of CA-125 was found in stage I carcinoma. Discriminant analysis of solid components and thickness of septations resulted in accurate diagnosis of 70.6% of the tumors (80.6% of BOTs and 69.7% of stage I carcinomas). Conclusion CA-125 levels for solid components and thickness of septations are lower in BOTs. These may be helpful in predicting the risk of carcinoma, even if BOTs cannot be conclusively differentiated from stage I carcinoma

    The choice of treatment in carcinoma of the cervix is best decided after careful individual appraisal has been carried out. For best results, a long-term view must be agreed upon initially and careful followup by the same team is obligatory. At present, surgery, radiation therapy, and a combination of these two modalities have been employed successfully to manage carcinoma of the cervix. To a great extent, the facilities, the experience, and the interest of the personnel involved influence the type of therapy that will be employed. Generally speaking, the choice of treatment is determined primarily by the stage of the disease process. Radical surgery in the management of patients with Stage I and Stage II-A carcinoma of the cervix must be planned to include within the en bloc dissection the uterus, tubes, ovaries, and regional lymph node drainage from those organs. Therefore, a radical lymphadnectomy is an integral and important part of the overall management program when radical surgery is performed. In most institutions, radiation therapy is used most frequently to treat carcinoma of the cervix in Stages I and II-A. The data from various institutions indicate significant survival potential from radiation therapy treatment programs that are appropriately devised. In Stages I and II-A the complications are minimal in character (primarily proctitis and cystitis); generally, they involve a potential incidence of about six percent

    Molecular biological research on nasopharyngeal carcinoma has been widely practiced, such as VEGF, EGFR, COX-2 expression and so on. MAPK plays a role in cell growth such as proliferation, differentiation, and apoptosis, primarily contributing to gene expression, where p38 MAPK pathway mostly associate with anti-apoptosis and cause cell transformation. The aim of this study is to determine the expression of p38 MAPK in clinical stage of nasopharyngeal carcinoma so that the result can be helpful in prognosis and adjunctive therapy in nasopharyngeal carcinoma. The research design is descriptive. It was done in THT- KL Department of FK USU/RSUP Haji Adam Malik, Medan and Pathology Anatomical Department of FK USU. The study was conducted from December 2011 to May 2012. The Samples are all patients who diagnosed with nasopharyngeal carcinoma in oncology division of Otorhinolaryngology Department. p38 MAPK overexpression was found in 21 samples (70%) from 30 nasopharyngeal carcinoma samples. The elevated of p38 MAPK expression most found on T4 by eight samples (38.1%), N3 lymph node group by nine samples (42.9%), stage IV of clinical staging is as many as 15 samples (71.4%). p38 MAPK most expressed in stage IV clinical staging of patients with nasopharyngeal carcinoma.

    To determine the value of the perfusion parameters in predicting short-term tumour response to synchronous radiochemotherapy for cervical squamous carcinoma. Ninety-three patients with cervical squamous carcinoma later than stage IIB were included in this study. Perfusion CT was performed for all these patients who subsequently received the same synchronous radiochemotherapy. The patients were divided into responders and non-responders according to short-term response to treatment. Baseline perfusion parameters of the two groups were compared. The perfusion parameters that might affect treatment effect were analysed by using a multivariate multi-regression analysis. The responders group had higher baseline permeability-surface area product (PS) and blood volume (BV) values than the non-responders group (P 0.05). At multivariate multi-regression analysis, BV, PS and tumour size were significant factors in the prediction of treatment effect. Small tumours usually had high PS and BV values, and thus had a good treatment response. Perfusion CT can provide some helpful information for the prediction of the short-term effect. Synchronous radiochemotherapy may be more effective in cervical squamous carcinoma with higher baseline PS and BV. (orig.)

    Purpose: The squamous cell carcinoma (SCC) antigen is still considered the most accurate serologic tumor marker in cervical carcinoma. We assessed the contribution of the SCC assay to the detection of recurrences in patients treated with radiotherapy. Methods and Materials: The pattern of recurrence and follow-up data were prospectively recorded for 135 patients. Of the 135 patients, 103 (76.3%) had primary cervical carcinoma and 32 (23.7%) had already experienced disease recurrence that had been successfully treated with surgery (n = 2), surgery plus radiotherapy (n = 2), radiotherapy (n = 5), or concomitant chemoradiotherapy (n = 23). The follow-up evaluations (chest X-ray, abdominopelvic magnetic resonance imaging, gynecologic examination with colposcopy, Papanicolaou smear, and SCC assay) were performed at 6-month intervals; the evaluation was done earlier if recurrent disease was suspected. The median follow-up time was 29 months (range, 6-131). The SCC serum levels were assayed, and a cost analysis was done. Results: A total of 481 SCC determinations were performed. Of the 135 patients, 43 (31.8%) experienced disease recurrence. The SCC levels were higher in those with recurrent disease than in the disease-free patients. Elevation of SCC was documented in 34 (79.1% sensitivity) of 43 recurrences before symptoms appeared. Of the 38 patients with serum SCC elevation, 34 developed a recurrence (positive predictive value, 89.5%). Of the 97 patients with negative SCC serum levels, 88 had negative findings at the clinicoradiologic evaluation (negative predictive value, 90.7%). A simplified approach (SCC plus gynecologic examination) was evaluated. Compared with the complete follow-up program, the rate of missed recurrence was 2.2%. The total projected cost per patient for 5 years of follow-up for the simplified procedure was approximately 12.2-fold lower than the standard approach. Conclusions: Our results have shown that a simplified diagnostic approach, including

    Objective: To determine whether diffusion-weighted imaging (DWI) can be used for quantitatively evaluating severity of acute radiation proctopathy after radiotherapy for cervical carcinoma. Materials and methods: One hundred and twenty-four patients with cervical carcinoma underwent MR examination including DWI before and after radiotherapy. Acute radiation proctopathy was classified into three groups (grade 0, grade I–II and grade III–IV) according to Toxicity Criteria of the Radiation Therapy Oncology Group (RTOG). The pretreatment ADC (ADC{sub pre}), ADC after treatment (ADC{sub post}) and ADC change (ΔADC) were compared among three groups. In addition, acute radiation proctopathy was classified into good-prognosis group and poor-prognosis group. ADC{sub pre}, ADC{sub post} and ΔADC were compared between two groups. For DWI parameter that had significant difference, discriminatory capability of the parameter was determined using receiver operating characteristics (ROC) analysis. Results: ADC{sub post} and ΔADC were higher in grade I–II group than in grade 0 group (p < 0.05), yielding a sensitivity of 79.3% and specificity of 69.4% for ADC{sub post}, and 85.1%, 72.3% for ΔADC for discrimination between two groups. ADC{sub post} and ΔADC were higher in grade III–IV group than in grade I–II group (p < 0.05), yielding a sensitivity of 80.3% and specificity of 72.5% for ADC{sub post}, and 84.1%, 74.5% for ΔADC for discrimination between two groups. ADC{sub post} and ΔADC were higher in poor-prognosis group than in good-prognosis group (p < 0.05), yielding a sensitivity of 79.5% and specificity of 73.4% for ADC{sub post}, and 87.2%, 78.3% for ΔADC for discrimination between two groups. Conclusion: Diffusion-weighted MRI can be used for quantitative stratification of severity of acute radiation proctopathy, which serves as an important basis for appropriate timely adjustment of radiotherapy for cervical carcinoma in order to maximally reduce the

    This study aimed to determine the correlation between the volumetric parameters derived from the images of the second, third, and fourth cervical vertebrae by using cone beam computed tomography with skeletal maturation stages and to propose a new formula for predicting skeletal maturation by using regression analysis. We obtained the estimation of skeletal maturation levels from hand-wrist radiographs and volume parameters derived from the second, third, and fourth cervical vertebrae bodies from 102 Japanese patients (54 women and 48 men, 5-18 years of age). We performed Pearson's correlation coefficient analysis and simple regression analysis. All volume parameters derived from the second, third, and fourth cervical vertebrae exhibited statistically significant correlations (P cervical-vertebra volume as an independent variable with a variance inflation factor less than ten. The explanation power was 81.76%. Volumetric parameters of cervical vertebrae using cone beam computed tomography are useful in regression models. The derived regression model has the potential for clinical application as it enables a simple and quantitative analysis to evaluate skeletal maturation level.

    Only a limited number of studies have evaluated the efficacy of {sup 18}F-FDG PET/CT for recurrent cervical carcinoma, which this study seeks to expand upon. This is a retrospective study of 30 women with cervical carcinoma who had a surveillance PET/CT after initial therapy. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were calculated using a 2 x 2 contingency table with pathology results (76%) or clinical follow-up (24%) as the gold standard. The Wilson score method was used to perform 95% confidence interval estimations. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of PET/CT for the detection of local recurrence at the primary site were 93, 93, 93, 86, and 96%, respectively. The same values for the detection of distant metastases were 96, 95, 95, 96, and 95%, respectively. Seventy-one percent of the scans performed in symptomatic patients showed true-positive findings. In comparison, 44% of scans performed in asymptomatic patients showed true-positive findings. But, all patients subsequently had a change in their management based on the PET/CT findings such that the effect was notable. The maximum standardized uptake value ranged from 5 to 28 (average: 13 {+-} 7) in the primary site and 3 to 23 (average: 8 {+-} 4) in metastases which were significantly different (p = 0.04). This study demonstrates favorable efficacy of {sup 18}F-FDG PET/CT for identification of residual/recurrent cervical cancer, as well as for localization of distant metastases. (orig.)

    Angiogenesis plays a pivotal role in the progression of tumours through the formation of new blood vessels. Vascular endothelial growth factor (VEGF) is a chief factor responsible for inducing and regulating angiogenesis. Additionally, the human epidermal growth factor receptor family of receptors also plays an important role in the pathogenesis of tumours. This study aimed to examine the association between VEGF and Her-2 protein expression and its correlation with clinic-pathological characteristics; in particular, prognosis. A total of 65 cases of cervical carcinoma and 10 samples of inflammatory lesions were evaluated for VEGF and Her-2 protein expression. Expression of VEGF and Her-2 was detected in 63.07% and 43.07% in cervical carcinoma cases respectively whereas control cases did not show any expression. The difference in the expression pattern of both markers comparing cancer and control cases was statistically significant (p 0.05). Comparing different grades of a tumour, expression of Her-2 was detected in 31.8% of well-differentiated tumours, 36.0 % in moderately differentiated tumours and 66.66 % in poorly differentiated cancers. The expression of Her-2 was increased in high-grade tumours, and the difference of expression level between tumour grades was statistically significant (p 0.05). The present study supports earlier findings that over-expression / up-regulation of VEGF and Her - 2 is linked with poor prognosis and may play a vital role in the development and progression of cervical cancer.

    Growth and its prediction are important for the success of many orthodontic treatments. The aim of this study was to determine the reliability of the cervical vertebral maturation (CVM) method for the assessment of mandibular growth. A group of 20 orthodontic clinicians, inexperienced in CVM staging, was trained to use the improved version of the CVM method for the assessment of mandibular growth with a teaching program. They independently assessed 72 consecutive lateral cephalograms, taken at Liverpool University Dental Hospital, on 2 occasions. The cephalograms were presented in 2 different random orders and interspersed with 11 additional images for standardization. The intraobserver and interobserver agreement values were evaluated using the weighted kappa statistic. The intraobserver and interobserver agreement values were substantial (weighted kappa, 0.6-0.8). The overall intraobserver agreement was 0.70 (SE, 0.01), with average agreement of 89%. The interobserver agreement values were 0.68 (SE, 0.03) for phase 1 and 0.66 (SE, 0.03) for phase 2, with average interobserver agreement of 88%. The intraobserver and interobserver agreement values of classifying the vertebral stages with the CVM method were substantial. These findings demonstrate that this method of CVM classification is reproducible and reliable. Copyright © 2016 American Association of Orthodontists. Published by Elsevier Inc.

    Human papillomavirus (HPV) is one of the most widely publicized and researched pathogenic DNA viruses. For decades, HPV research has focused on transforming viral activities in cervical cancer. During the past 15 years, however, HPV has also emerged as a major etiological agent in cancers of the head and neck, in particular squamous cell carcinoma. Even with significant strides achieved towards the screening and treatment of cervical cancer, and preventive vaccines, cervical cancer remains the leading cause of cancer-associated deaths for women in developing countries. Furthermore, routine screens are not available for those at risk of head and neck cancer. The current expectation is that HPV vaccination will prevent not only cervical, but also head and neck cancers. In order to determine if previous cervical cancer models for HPV infection and transformation are directly applicable to head and neck cancer, clinical and molecular disease aspects must be carefully compared. In this review, we briefly discuss the cervical and head and neck cancer literature to highlight clinical and genomic commonalities. Differences in prognosis, staging and treatment, as well as comparisons of mutational profiles, viral integration patterns, and alterations in gene expression will be addressed.

    Introduction: Nodal metastases in cervical cancer have prognostic implications. Imaging is used as an adjunct to clinical staging for evaluation of nodal metastases. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has an advantage of superior resolution of its CT component and detecting nodal disease based on increased glycolytic activity rather than node size. But there are limited studies describing its limitations in early stage cervical cancers. Objective: We have done meta-analysis with an objective to evaluate the efficacy of FDG PET/CT and its current clinical role in early stage and operable cervical cancer. Materials and Methods: Studies in which FDG PET/CT was performed before surgery in patients with early stage cervical cancers were included for analysis. PET findings were confirmed with histopathological diagnosis rather than clinical follow-up. FDG PET/CT showed lower sensitivity and clinically unacceptable negative predictive value in detecting nodal metastases in early stage cervical cancer and therefore, can not replace surgicopathological staging. False negative results in presence of microscopic disease and sub-centimeter diseased nodes are still the area of concern for metabolic imaging. However, these studies are single institutional and performed in a small group of patients. There is enough available evidence of clinical utility of FDG PET/CT in locally advanced cervical cancer. But these results can not be extrapolated for early stage disease. Conclusion: The current data suggest that FDG PET/CT is suboptimal in nodal staging in early stage cervical cancer. PMID:23559711

    Full text: Non-invasive methods of pre-operative staging of non-small cell bronchogenic carcinoma are inaccurate. To determine the clinical role of positron emission tomography (PET) in the mediastinal staging of lung carcinoma, {sup 18}F-fluorodeoxyglucose (FDG) studies were performed in 25 patients with suspected non-small cell bronchogenic carcinoma and correlated with pathology. The patients comprised 20 men and 5 women (mean age 63; range 43-78 y). All patients had proven non-small cell lung carcinoma, except two, one patient with benign inflammatory disease and the other with small cell carcinoma. The FDG PET studies were acquired on a Siemens 951131R body tomography over 2-3 bed positions to include the thorax and mediastinum. The PET images were interpreted for tumour involvement of mediastinal nodes according to the American Thoracic Society classification and scored for confidence of tumour presence on a 5 point scale. The intensity of glucose metabolism was compared to mediastinal blood pool activity and graded on a 4 point scale. FDG PET correctly excluded ipsilateral mediastinal nodal (N2) disease in 16 of 16 patients. Six of nine patients with N2 disease were correctly identified by FDG PET. Of the three patients with N2 nodal involvement not detected by PET, each had single station nodal disease, and in two patients the primary lesions abutted the involved nodal group. A total of 104 nodal stations were sampled or examined at surgery. FDG PET correctly excluded disease in 83/83 (100% specificity) negative nodal stations. FDG PET is a promising non-invasive functional imaging modality for the mediastinal staging of bronchogenic carcinoma.

    Full Text Available ABSTRACT INTRODUCTION: It is well established that cervical lymph node metastasis is the most important prognostic factor in patients with oral squamous cell carcinoma of the upper aerodigestive tract. The definition of parameters and classifications that could separate patients in groups of low, intermediate and high-risk is being attempted for several years. OBJECTIVE: The objective of this study was to determine possible predictive factors related to the occurrence of occult cervical lymph node metastasis through the analysis of histopathological reports of surgical specimens obtained after oral squamous cell carcinoma resection and selective neck dissections of patients initially classified as N0. METHODS: This was a primary, retrospective, observational, case-control study. Histopathological reports were reviewed to determine if some findings were related to the occurrence of occult lymph node metastasis. The events analyzed were oral cavity subsites, pT-stage, muscular infiltration, desmoplasia, vascular emboli, perineural infiltration, tumor thickness and compromised margins. RESULTS: Occult cervical metastasis accounted for 19.10 percent of the cases. Desmoplasia, perineural infiltration, tumor thickness and pT4a stage are predictive factors of occult neck metastasis (p-value = 0.0488, 0.0326, 0.0395, 0.0488, respectively. CONCLUSION: The accurate definition of predictive factors of occult cervical metastasis may guide the selection of patients that should be referred to radiotherapy, avoiding the unnecessary exposure of low-risk patients to radiation and allowing a better regional control of the disease in those of moderate or high risk.

    Full Text Available INTRODUCTION: Transient hypoxia and subsequent reoxygenation are common phenomena in solid tumors that greatly influence the outcome of radiation therapy. This study was designed to determine how varying cycles of hypoxia/reoxygenation affect the response of cervical carcinoma cells irradiated under oxic and hypoxic conditions and whether this could be modulated by proteasome inhibition. MATERIALS AND METHODS: Plateau-phase SiHa cervical carcinoma cells in culture were exposed to varying numbers of 30-minute cycles of hypoxia/reoxygenation directly before irradiation under oxic or hypoxic conditions. 26S Proteasome activity was blocked by addition of MG-132. Clonogenic survival was measured by a colonyforming assay. RESULTS: Under oxic conditions, repeated cycles of hypoxia/reoxygenation decreased the clonogenic survival of SiHa cells. This effect was even more pronounced after the inhibition of 26S proteasome complex. In contrast, under hypoxic conditions, SiHa cells were radioresistant, as expected, but this was increased by proteasome inhibition. CONCLUSIONS: Proteasome inhibition radiosensitizes oxygenated tumor cells but may also protect tumor cells from ionizing radiation under certain hypoxic conditions.

    Full Text Available The association of human papilloma virus (HPV infection and cervical intraepithelial neoplasia (CIN is well recognized. Interaction of HPV oncogenic proteins with cellular regulatory proteins leads to up regulation of p16 INK4A , a CDK inhibitor, which is a biomarker for HPV infection. We investigated p16 expression in CIN and invasive squamous cell carcinoma (SCC which has not been reported in the Indian population previously. Materials and Methods: Retrospective analysis of 100 cases with 20 cases each of histologically normal cervical epithelium, CIN1, 2, 3 and invasive SCC for p16 expression was performed by immunohistochemistry using commercially available mouse monoclonal antibody to p16 (clone 6H12. Statistical Analysis: For differences in expression among groups, statistical analysis was carried out using ANOVA and post hoc test of Scheffe. Results: p16 immunoreactivity was found to be both nuclear and/or cytoplasmic. The normal cervical epithelium was predominantly negative for p16 (18/20. There was a progressive increase of p16 expression with the grade of CIN. In CIN 1, two cases (20% showed nuclear and nucleocytoplasmic positivity respectively. In contrast, diffuse strong nuclear or nucleocytoplasmic expression was observed in 45 and 55% cases of CIN 2 and CIN 3 respectively. All except one squamous cell carcinoma stained strongly positive for p16. The difference in expression between CIN 2/3 and SCC versus normal cervix was found highly significant (p is equal to 0.008 and p less than 0.001. Conclusions: p16 expression correlates excellently with the grade of CIN and is a sensitive marker of cervical intraepithelial neoplasia.

    Objective: To analyse the clinical characteristics of patients with uterus effusion after irradiation for carcinoma of the cervix. Methods: 151 patients with uterus effusion after irradiation for carcinoma of the cervix were retrospectively analyzed. Results: All these 151 patients who had been treated by radiotherapy had FIGO stage IIB or IIIB lesions including 32 adenocarcinomas. The most common symptom was irregular vaginal discharge or drainage (65 patients), followed by irregular vaginal bleeding (32 patients), and abdominal or pelvic mass (27 patients). Twenty-seven patients were entirely asymptomatic. The positive rate of uterus effusion found by B-ultrasound scan was 100%. When uterus effusion was found, 87 patients (57.6%) had malignant tumor, including 62 with residual or recurrent cervical carcinoma and 25 with secondary primary malignant uterus tumor. Sixty-four patients had uterus effusion alone including 8 with pyometra. Of these 64 patients, 17 underwent abdominal hysterectomy with bilateral salpingo-oophorectomy (BSOH), the others were treated with drainage till the fluid disappeared. Of the 62 patients with residual or recurrent cervical carcinoma, 19 underwent BSOH and 43 were treated by palliative irradiation or chemotherapy. Twenty-five patients who had secondary primary malignant uterus tumor were treated by BSOH. The 5-year survival rate of patients with uterus effusion alone, with residual tumor (with recurrent tumor), or with secondary primary malignancy were 54.8%, 0%, 28.7% and 47.5%, respectively. The prognosis of the patients with uterus effusion alone was better than those with secondary primary malignant uterus tumor. Patients with residual or recurrent cervical cancer had the worst prognosis. Conclusions: Patients with uterus effusion after irradiation for carcinoma of the cervix often have tumor including secondary primary, malignant uterus tumor. The prognosis is different, which depends on if the patient has tumor or not. (authors)

    PURPOSE/OBJECTIVE: To evaluate the outcome of patients treated with radiotherapy for carcinoma metastatic to cervical lymph nodes from an unknown primary site. This large retrospective series updates the results of our treatment policy in which patients receive radiation both to the involved neck(s) at risk as well as putative mucosal primary sites along the pharyngeal axis. MATERIALS/METHODS: Between July 1968 and December 1992, 196 patients with carcinoma metastatic to cervical lymph nodes from an unknown primary site were treated with curative intent using megavoltage external beam radiotherapy. One hundred thirty-nine patients received adjuvant radiation following either an excisional biopsy or neck dissection (S+XRT), and 57 received radiation to gross disease following either a diagnostic biopsy or incomplete resection (XRT). A neck dissection was performed following radiation in patients in the XRT group who were medically and technically operable if there were residual masses following radiation. Nodal stage distribution was as follows: N1 - 32 patients, N2a - 65, N2b - 35, N2c - 15, N3 - 36, and NX - 13. Thirty percent of patients in the XRT group had N3 disease vs. 14% in the S+XRT group (p = .008). Similarly, 33% of patients in the XRT group presented with low jugular or supraclavicular adenopathy compared with 16% in the S+XRT group (p = .006). Radiation was delivered to putative mucosal sites in 173 patients. Of these, 172 were treated to the oropharynx, 167 to the nasopharynx, 124 to the larynx and hypopharynx, and 5 to the oral cavity. All but one patient received bilateral treatment when covering putative mucosal primary sites. Treatment was limited to the ipsilateral neck only in 23 patients. Doses ranged from 24 to 90 Gy. The median doses to the sites of nodal involvement were 63 Gy and 68.1 Gy for the S+XRT and XRT groups, respectively. RESULTS: The range of follow-up was 1-267 months with a median follow-up in surviving patients of 87 months

    Background The β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3) encodes a member of the B3GNT family that functions as the backbone structure of dimeric sialyl-Lewis A and is involved in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. B3GNT3 has been implicated as an important element in the development of certain cancers. However, the characteristics of B3GNT3 in the development and progression of cancer remain largely unknown. Thus, our study aimed to investigate the expression pattern and the prognostic value of B3GNT3 in patients with early-stage cervical cancer. Methods The mRNA and protein levels of B3GNT3 expression were examined in eight cervical cancer cell lines and ten paired cervical cancer tumors, using real-time PCR and western blotting, respectively. Immunohistochemistry (IHC) was used to analyze B3GNT3 protein expression in paraffin-embedded tissues from 196 early-stage cervical cancer patients. Statistical analyses were applied to evaluate the association between B3GNT3 expression scores and clinical parameters, as well as patient survival. Results B3GNT3 expression was significantly upregulated in cervical cancer cell lines and lesions compared with normal cells and adjacent noncancerous cervical tissues. In the 196 cases of tested early-stage cervical cancer samples, the B3GNT3 protein level was positively correlated with high risk TYPES of human papillomavirus (HPV) infection (P = 0.026), FIGO stage (P cervical cancer patients. Conclusions Our study demonstrated that elevated B3GNT3 expression is associated with pelvic lymph node metastasis and poor outcome in early-stage cervical cancer patients. B3GNT3 may be a novel prognostic marker and therapeutic target for the treatment of cervical cancer. PMID:26709519

    28 Patients with colon carcinoma (excluding the recto-sigmoid region) underwent preoperative staging with computed tomography (CT). The CT had a sensitivity of 60 and 67 per cent for detection of extramural invasion, 75 per cent sensitivity and specificity for lymph node metastases and a sensitivity of 87 per cent and specificity of 95 per cent for liver metastases. Compared with the modified Dukes classification, CT correctly staged 50 per cent of the patients with Dukes A lesions; 40 per cent with Dukes B, 75 per cent with Dukes C and 85 per cent with Dukes D lesions. The data presented in this study showed that CT has limitations in the sensitivity and accuracy of staging local colonic carcinoma. However, the authors recommend its use for patients who are clinically suspected of having extensive disease. (author). 10 refs.; 4 figs.; 2 tabs

    Purpose: To discuss a variety of technical and clinical issues concerning the management of carcinoma of the uterine cervix. Radiation therapy plays a central role in the management of patients with invasive carcinoma of the uterine cervix. Although survival rates are high for patients with small volume disease, clinicians continue to search for approaches that might improve treatment results for patients who have bulky central disease, evidence of regional dissemination or other factors associated with a high rate of disease recurrence. New technical approaches have contributed to controversy about the best means of optimizing therapeutic ratio. This course will review current approaches to the management of cervical cancer. Technical aspects of intracavitary and external beam treatment will be emphasized. Problems with brachytherapy dose specification will be discussed as will technical factors that may influence the incidence of treatment-related complications. Current understanding of the natural history of disease and of clinical factors that influence the rate of disease recurrence will be reviewed, including the importance of tumor volume, lymph node involvement, and histologic type on natural history and prognosis. The possible role of controversial methods of clinical evaluation such as lymphangiography and surgical staging will be discussed. Some of the more controversial aspects of treatment including the indications of radiation therapy vs. surgical therapy for stage IB disease, the role of extended field therapy, postoperative therapy, adjuvant hysterectomy, and neoadjuvant or concurrent chemotherapy will be discussed. Conclusions from the recent NCI consensus conference on cervical cancer will be reviewed

    Purpose: To investigate the value of diffusion-weighted MR imaging (DWI) in detection of cervical cancer, and to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) values for evaluating cervical cancer before and after chemoradiotherapy. Materials and methods: Thirty-three patients with cervical squamous carcinoma and 20 patients with other pelvic abnormalities underwent diffusion-weighted imaging (DWI) in addition to routine MR imaging. The ADC values of normal cervical tissue, cervical area before and after chemoradiotherapy were measured and compared. Receiver operating characteristic (ROC) analysis was employed to investigate whether ADC values could help in discrimination among normal cervical tissue, cervical cancer before and after therapy, and to obtain the optimal ADC threshold value. Results: Cervical cancer lesion demonstrated obviously hyperintensity on DWI images. The mean ADC value of cervical carcinoma (1.110 ± 0.175 x 10 -3 mm 2 /s) was significantly lower than that of normal cervical tissue (1.593 ± 0.151 x 10 -3 mm 2 /s) (P -3 mm 2 /s) was significantly higher than that before therapy (1.013 ± 0.094 x 10 -3 mm 2 /s) (P -3 mm 2 /s, between cervical area before and after therapy was 1.255 x 10 -3 mm 2 /s, between normal cervical tissue and cervical area after therapy was 1.525 x 10 -3 mm 2 /s. The sensitivity and specificity were 100% and 84.8%, 95.5% and 100%, 70% and 81.8%, respectively. Conclusion: DWI can be applied for the detection of cervical cancer because of its superior disease contrast with normal tissue. The measurement of the ADC values can be a useful tool to monitor the response to therapy for cervical carcinoma.

    Determining the risk factors associated with parametrial involvement (PMI) is of paramount importance to decrease the multimodality treatment in early-stage cervical cancer. We investigated the preoperatively assessable clinical and pathological risk factors associated with PMI in surgically treated stage IB1-IIA2 cervical cancer. A retrospective cohort study of women underwent Querleu-Morrow type C hysterectomy for cervical cancer stage IB1-IIA2 from 2001 to 2015. All patients underwent clinical staging examination under anesthesia by the same gynecological oncologists during the study period. Evaluated variables were age, menopausal status, body mass index, smoking status, FIGO (International Federation of Obstetrics and Gynecology) stage, clinically measured maximal tumor diameter, clinical presentation (exophytic or endophytic tumor), histological type, tumor grade, lymphovascular space invasion, clinical and pathological vaginal invasion, and uterine body involvement. Endophytic clinical presentation was defined for ulcerative tumors and barrel-shaped morphology. Two-dimensional transvaginal ultrasonography was used to measure tumor dimensions. Of 127 eligible women, 37 (29.1%) had PMI. On univariate analysis, endophytic clinical presentation (P = 0.01), larger tumor size (P PMI. In multivariate analysis endophytic clinical presentation (odds ratio, 11.34; 95% confidence interval, 1.34-95.85; P = 0.02) and larger tumor size (odds ratio, 32.31; 95% confidence interval, 2.46-423.83; P = 0.008) were the independent risk factors for PMI. Threshold of 31 mm in tumor size predicted PMI with 71% sensitivity and 75% specificity. We identified 18 patients with tumor size of more than 30 mm and endophytic presentation; 14 (77.7%) of these had PMI. Endophytic clinical presentation and larger clinical tumor size (>3 cm) are independent risk factors for PMI in stage IB-IIA cervical cancer. Approximately 78% of the patients with a tumor size of more than 3 cm and endophytic

    The purpose of this study was to assess the suitability of a percutaneously implantable catheter port system (PIPS)for repeated intraarterial locoregional chemotherapy (ILC) for cervical and endometrial carcinoma. In 30 patients with advanced, recurrent, or high-risk cervical (n 23) or endometrial(n = 7) carcinoma, PIPS for ILC was implanted via a femoral access, the catheter localized in the infrarenal abdominal aorta. Chemotherapy was performed adjuvantly after surgery(n = 14) or neo-adjuvantly to enable surgery, or for palliation (n = 16). Port implantation, catheter placement, and repeated port puncture was uneventful in all patients.Complications included catheter dislocation (n = 1),catheter thrombosis (n = 2), subcutaneous infection(n = 1), port-bed skin atrophy (n = 1),requiring port explantation in 3 patients. At 2 years follow-up,complete remission was observed in 7/14 patients with adjuvant chemotherapy, partial remission in 3/14. Successful down-staging could be achieved in 4/8 patients with neo-adjuvant chemotherapy. The PIPS is suitable for repeated ILC which may be a valuable method for pre- and post-surgical therapy of advanced or high-risk cervical and endometrial cancer, for adjuvant chemotherapy as well as neo-adjuvantly for down-staging, or for palliation

    Currently, a PET-CT is used to assess the need for extended field radiotherapy of para-aortic lymph nodes (PALN) in International Federation of Gynaecology and Obstetrics (FIGO) stage IB2, IIA2-IVA (locally advanced stage) cervical cancer. A small study established a sensitivity and specificity estimate for PALN metastases of 50% (95% CI; 7-93%) and 83% (95% CI; 52-98%), respectively. Surgical staging of PALN may lead to a higher diagnostic accuracy. However, surgical staging of para-aortic lymph nodes in locally advanced stage cervical cancer is not common practice. Therefore, a phase 2 randomised controlled trial is needed to assess its safety and feasibility. In addition to standard imaging (MRI or CT scan) with PET-CT, 30 adult women with FIGO stage IB2, IIA2-IVA cervical cancer will be randomised to receive either surgical staging or usual PET-CT staging. Administering extended field radiotherapy will be based on lymphadenectomy results for the intervention group and on the PET-CT results for the control group. Follow-up visits at 0, 3, 6, 9 and 12 months will assess health-related quality of life and progression-free survival.Primary safety and feasibility outcomes of surgical staging will be assessed by calculating means with 95% confidence intervals for duration of surgery, number of complications, blood loss, nodal yield after para-aortic lymphadenectomy and treatment delay due to surgical staging. Secondary patient-centred outcomes on quality of life and first year survival will be documented and compared between the two groups. Estimates of sensitivity, specificity and negative and positive predictive values of MRI, PET-CT and surgical staging will be presented with 95% CI.. All analysis will be performed according to the intention to treat principle. This study will assess safety and feasibility, expressed as the number and severity of complications, effect on quality of life and the treatment delay due to surgically staging para-aortic lymph nodes in

    Abstarct: Background and purpose: Tumor recurrence after surgery for cervical carcinoma is associated with high fatality and morbidity, forming a major therapeutic challenge. This paper presents our experience with treatment of this patient group by salvage radiotherapy with curative intent. Materials and methods: Thirty-five patients with a pelvic recurrence after hysterectomy received high-dose radiotherapy. A retrospective analysis of long-term outcome and prognostic factors was performed. Results: After a median follow-up period of 12.1 years, actuarial 2-,5- and 10-year overall survival rates were 66%, 43% and 33%; disease-free survival rates were 62%, 45% and 41%, respectively. Pelvic control rates at 2-,5- and 10-years were 77%, 69% and 62%. Unfavorable prognostic factors on univariate analysis for survival were: recurrence extending to the pelvic wall versus central recurrence, early recurrence after surgery, external boost versus brachytherapy boost, low total dose and high age. Only a brachytherapy boost and a long interval between surgery and recurrence were significant on multivariate analysis. Severe complications (≥grade 3) were seen in 6 patients (17%; actuarial after 5 years, 21%). Conclusions: Salvage radiotherapy for recurrent cervical carcinoma following surgery may result in 40-50% long-term disease-free survival and an acceptable risk of severe treatment complications, even in patient with recurrences extending to the pelvic wall

  1. Use of Cetuximab in Combination with Cisplatin and Adjuvant Pelvic Radiation for Stage IIIB Vulvar Carcinoma

    Full Text Available Vulvar cancer is a rare carcinoma constituting only 4% of gynecologic malignancies and 0.6% of female cancers. Most chemotherapy regimens have been created from extrapolation from anal and cervical cancer research. Advanced stages have the worst prognosis and oftentimes invasive surgical procedures are needed to cure disease with high recurrence rates. Case. A 50 yo G2P2 presented for a 2 cm mass in her right labia. The patient underwent a partial radical vulvectomy and bilateral superficial and deep inguinal lymph node dissection. Bilateral inguinal lymph nodes were positive for residual disease. The patient underwent whole pelvic radiation with cisplatin as a radiosensitizer. The primary tumor was epidermal growth factor receptor (EGFR positive and cetuximab, a monoclonal antibody to EGFR, was added. The patient underwent seven cycles of chemotherapy including cisplatin and cetuximab with adjuvant radiation therapy to the pelvis. She currently is without evidence of disease recurrence since completing treatment 4 years ago. Conclusion. One previous case report showed short-term palliative success of five months for recurrent, metastatic vulvar cancer. This case suggests that cetuximab could possibly be used in initial management of patients with advanced stages of vulvar cancer to improve prognosis.

    Lymph node metastasis (LNM) is known to be the most important prognostic factor in cervical cancer. We analyzed the number of positive lymph nodes and other clinicopathological factors as prognostic factors for survival in node-positive patients with cervical cancer. Node-positive cervical cancer patients (n=108) who underwent radical hysterectomy and systematic lymphadenectomy in Hokkaido University Hospital from 1982 to 2002 were enrolled. Clinicopathological data including age, stage, histologic subtype, and the number of LNM sites were collected. The main outcome was the overall survival (OS) rate for Stage Ib-IIb patients treated with surgery and postoperative radiotherapy. The 5-year OS rate of patients with 1 positive node was 93.3%, that for 2 nodes was 77.3%, for 3 nodes it was 33.3%, and for 4 or more it was 13.8%. The OS rate of patients with 1 or 2 LNM sites was significantly better than that for patients with more than 2 LNM sites. The OS rate of patients with adenocarcinoma (Ad) (28.6%) was significantly lower than that for patients with other histologic subtypes (squamous cell carcinoma; 66.7%, adenosquamous carcinoma; 75.0%, p=0.0003). Multivariate analysis revealed that >2 LNM sites and Ad were independent prognostic factors for survival. The 5-year OS rate of patients with 1 or 2 LNM sites was 86.8%, a more favorable prognosis than the OS rates in other reports. More than two LNM sites and adenocarcinoma were independent prognostic factors for node-positive patients with cervical cancer. (author)

    To compare and analyze the dosimetric characteristics of volumetric modulated arc therapy (VMAT) vs step-shoot intensity-modulated radiation therapy (sIMRT) for upper thoracic and cervical esophageal carcinoma. Single-arc VMAT (VMAT1), dual-arc VMAT (VMAT2), and 7-field sIMRT plans were designed for 30 patients with upper thoracic or cervical esophageal carcinoma. Planning target volume (PTV) was prescribed to 50.4 Gy in 28 fractions, and PTV1 was prescribed to 60 Gy in 28 fractions. The parameters evaluated included dose homogeneity and conformality, dose to organs at risk (OARs), and delivery efficiency. (1) In comparison to sIMRT, VMAT provided a systematic improvement in PTV1 coverage. The homogeneity index of VMAT1 was better than that of VMAT2. There were no significant differences among sIMRT, VMAT1, and VMAT2 in PTV coverage. (2) VMAT1 and VMAT2 reduced the maximum dose of spinal cord as compared with sIMRT (p < 0.05). The rest dose-volume characteristics of OARs were similar. (3) Monitor units of VMAT2 and VMAT1 were more than sIMRT. However, the treatment time of VMAT1, VMAT2, and sIMRT was (2.0 ± 0.2), (2.8 ± 0.3), and (9.8 ± 0.8) minutes, respectively. VMAT1 was the fastest, and the difference was statistically significant. In the treatment of upper thoracic and cervical esophageal carcinoma by the AXESSE linac, compared with 7-field sIMRT, VMAT showed better PTV1 coverage and superior spinal cord sparing. Single-arc VMAT had similar target volume coverage and the sparing of OAR to dual-arc VMAT, with shortest treatment time and highest treatment efficiency in the 3 kinds of plans.

    We evaluated the diagnostic performance of FDG-PET for the detection of metastatic cervical lymph nodes in recurrent papillary thyroid carcinoma patients with negative I-131 scan. All patients had total thyroidectomy and following I-131 ablation therapy. In the follow-up period, FDG-PET showed suspected cervical lymph nodes metastases and neck dissection was performed within 3 months after FDG-PET. It had shown for all patients the negative I-131 scan within 3 months before FDG-PET or negative I-131 scan during the period of cervical lymph nodes metastases suspected on the basis of FDG-PET, CT, or ultrasonography until the latest FDG-PET. Preoperative FDG-PET results were compared with the pathologic findings of lymph nodes specimens of 19 papillary thyroid carcinoma patients. Serum Tg, TSH, and Tg antibody levels at the time of latest I-131 scan were reviewed. The size of lymph node was measured by preoperative CT or ultrasonography. In 45 cervical lymph node groups dissected, 31 lymph node groups revealed metastasis. The sensitivity and specificity of FDG-PET for metastasis were 74.2% (23 of 31) and 50.0% (7 of 14), respectively. Except for patients with elevated Tg antibody levels, all patients showed the elevated serum Tg levels than normal limits at the TSH of =30uIU/ml. 8 lesions without suspected metastatic findings on FDG-PET revealed metastasis (false negative), and none of them exceeded 8mm in size (4 to 8mm, median= 6mm). On the other hand, 23 true positive lesions on FDG-PET were variable in size (6 to 17mm, median=9mm). FDG-PET is suitable for the detection of metastatic cervical lymph nodes in patients with recurrent papillary thyroid carcinoma. However, false positive or false negative should be considered according to the size of lymph node

    Hepatocellular carcinoma is the most common primary malignant tumor of the liver, and it is particularly prevalent in East and Southeast Asia. With surgical and/or local interventional treatment methods, survival rates for early-stage hepatocellular cancers have increased. However, it is not yet clear which staging systems are more applicable in hepatocellular carcinoma. Serum albumin level is already being used as a criterion in most staging systems. Albumin is an important serum protein in human bodily functions, but only 5 % of the daily amount needed is synthesized by the liver. The serum albumin level is affected by multifactorial situations, including capillary permeability, drugs, liver insufficiency, inflammation and/or infections, dehydration or overhydration, protein loosing disorders, and decreased nutrition intake in anorexia-malnutrition syndrome and cancer cachexia. Because of this complex situation, serum albumin level may affect many staging systems for hepatocellular carcinoma by leading to false-negative results. In this paper, the statuses of current staging systems are reviewed, and possible negative events regarding the serum albumin levels found in these staging systems are discussed.

    To evaluate the diagnostic accuracy and repeatability of the visual assessment of the cervical vertebral maturation (CVM) stages. Ten operators underwent training sessions in visual assessment of CVM staging. Subsequently, they were asked to stage 72 cases equally divided into the six stages. Such assessment was repeated twice in two sessions (T1 and T2) 4 weeks apart. A reference standard for each case was created according to a cephalometric analysis of both the concavities and shapes of the cervical vertebrae. The overall agreement with the reference standard was about 68% for both sessions and 76.9% for intrarater repeatability. The overall kappa coefficients with the reference standard were up to 0.86 for both sessions, and 0.88 for intrarater repeatability. Overall, disagreements one stage and twp stage apart were 23.5% (T1) and 5.1% (T2), respectively. Sensitivity ranged from 53.3% for CS5 (T1) to 99.9% for CS1 (T2), positive predictive values ranged from 52.4% for CS5 (T2) to 94.3% for CS6 (T1), and accuracy ranged from 83.6% for CS4 (T2) to 94.9% for CS1 (T1). Visual assessment of the CVM stages is accurate and repeatable to a satisfactory level. About one in three cases remain misclassified; disagreement is generally limited to one stage and is mostly seen in stages 4 and 5.

    Fifty patients with carcinoma of the uterine cervix received curative radiotherapy by external irradiation of the whole pelvis and intracavitary radiation at the Department of Therapeutic Radiology, Kangnam St. Mary Hospital from September,1983 to October, 1986. External beam whole pelvic irradiation was done first up to 4500-5940 cGy in 5 weeks to 6.5 weeks, followed by an intracavitary radiation. Total dose of radiation to point A varied from 6500 cGy to l1344 cGy (average 6764 cGy). Of the 50 patients, one patient was lost to follow up and follow up period of the remaining 49 patients ranged from 3 months to 93 months (median 32 months). According to FIGO classification, 6 (12.2%) were in stage I b, 6(12.2%) in stage I a, 25(51%) in stage II b, 7(14%) in stage III, and 5(10.2%) in stage IV. Age of the patients ranged from 33 to 76 years (Median 60 years). Pathologically, forty six(94%) patients had squamous cell carcinoma, 2 (4% had adenocarcinoma, and 1 (2%) had adenosquamous cell carcinoma. Overall response rate was 84%. 5-year survival rate was 49% for entire group (75% for stage I b, 83% for stage II a, 42.5% for stage II b, 25% for stage III, 40% for stage IV). Complications were observed in 11(22.4%) patients, who revealed rectal complications with most common frequency. Others were self limiting trifle ones such as wet desquamation, fatigue, mild leukopenia, etc. The correlation of the survival rate with various factors (age, dose, Hb level, pelvic lymph node status, performance status, local recurrence) was evaluated but showed no statistical significance except the age and local recurrence in this series; survival of patients less than 50 years of age was worse than that of the older, and the presence of local recurrence had worse prognosis(p< 0.05)

    Purpose: The present study presents the experience at the University of Florida with treatment of patients with squamous cell carcinomas (SCC) metastatic to cervical lymph nodes from an unknown head-and-neck mucosal (H and NM) site with radiotherapy (RT) alone or in combination with neck dissection (ND). Methods and Materials: The study included 126 patients treated with curative intent from 1964 to 1997. All patients had follow-up for at least 2 years. No patients were lost to follow-up. Results: Twelve patients (10%) developed SCC in H and NM sites at 0.5 to 10.9 years (median, 1.8 years). The rate of developing carcinomas in H and NM sites at 5 years was 13%. Histologic differentiation significantly affected the rate of developing carcinomas in H and NM sites in multivariate analysis. Sixteen patients (13%) had persistent nodal disease and 12 patients (10%) developed recurrent nodal disease at 0.5 to 10.9 years (median, 1.1 years). The nodal control rate at 5 years was 78%. Nodal size, N stage, and planned ND significantly affected the rate of nodal control in multivariate analysis. Nineteen patients (15%) developed distant metastasis at 0.2-5.1 years (median, 0.9 years). The distant metastases rate at 5 years was 14%. Extracapsular extension and RT dose significantly affected the risk of distant metastases in multivariate analysis. The overall absolute survival rate at 5 years was 47%. Extracapsular extension, N stage, RT dose for H and NM sites, and planned ND significantly affected absolute survival in multivariate analysis. The rate of cause-specific survival at 5 years was 67%. Extracapsular extension, nodal size, N stage, overall treatment time, and planned ND significantly affected cause-specific survival in multivariate analysis. Eight patients (6%) had severe postoperative complications and 6 patients (5%) had severe late complications. Conclusion: The present study supports the effectiveness of RT in lowering the rate of developing carcinomas in the H

    The human cervical cancer oncogene 1 (HCCR-1), a novel human oncoprotein, has been shown to be upregulated in various human tumors and plays a critical role in tumorigenesis and tumor progression. Here, the authors investigated HCCR-1 level in esophageal squamous cell carcinoma (ESCC) tissues and assessed the correlation between HCCR-1 level and prognosis of the patients with ESCC. HCCR-1 levels were investigated by immunohistochemistry, in situ hybridization, real-time quantitative RT-PCR and Western blotting methods; Kaplan-Meier curve was used to evaluate the prognostic value of HCCR-1 level in patients with ESCC using log-rank test. HCCR-1 displayed high levels in ESCC tissues compared to squamous dysplasia tissues and normal esophageal epithelial tissues. No significant correlation was observed between the levels of HCCR-1 mRNA and protein and gender and age (all p>0.05) but obviously related to histological grade, clinical stage, and lymph node metastasis (all p<0.001). Moreover, the survival rate of the patients with low HCCR-1 levels was higher than that of the patients with high HCCR-1 levels (both p<0.05). These data demonstrate that HCCR-1 may be used as a novel predictor for the prognosis of the patients with ESCC.

    Purpose: The present study reviews the experience in treatment of 447 patients with nasopharyngeal carcinomas, analyzing patient, tumor and treatment characteristics determining outcome. Materials and methods: There were 322 males and 125 females, their ages ranging from 7 to 85 years (median, 45 years). Two-hundred and seventy-two patients had World Health Organization (WHO) type 3 carcinomas, 123 patients had T4 tumors and 320 patients had metastatic cervical lymph nodes. Three-hundred and eight patients were treated with radiation therapy alone and 139 patients with chemotherapy in combination with radiation therapy. Cumulative radiation dose to primary tumor ranged from 50 to 76 Gy (median, 70 Gy) and radiation dose to metastatic cervical lymph nodes ranged from 46 to 74 Gy (median, 66 Gy). Results: Follow-up ranged from 0.1 to 19.5 years (mean, 7.6 years). Local complete response was achieved in 357 patients. In multivariate analysis, T-classification, cumulative radiation dose to primary tumor and treatment with chemotherapy in combination with radiation therapy predicted local response. Nodal complete response was achieved in 272 patients. In multivariate analysis, N-classification and radiation dose to metastatic cervical lymph nodes predicted nodal response. Local failure was observed in 70 patients, nodal failure in 35 patients and systemic failure in 114 patients. Overall survival, disease-free survival and disease-specific survival were 33, 32 and 37%, respectively, at 10 years. In multivariate analysis, age, T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted overall survival whereas T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted both disease-free survival and disease-specific survival. Conclusions: Radiation therapy alone appears to be an adequate and viable treatment for patients with early-stage

    A total of 91 cases of uterine cervical cancer, consisting of 38 cases of carcinoma in situ (CIN III) and 53 cases of stage I-IV cervical cancer, were retrospectively and clinicopathologically analyzed. The standard treatment given to these patients consisted of hysterectomy or conization for CIN III; observation of cases of mild to moderate dysplasia; radical hysterectomy plus pelvic lymph node dissection for stage I and II cervical cancer; and radiotherapy for stage III and IV cervical cancer. Postoperative irradiation consisted of irradiation of the whole pelvis with 40-50 Gy. The patients who were not treated surgically underwent 40 Gy external irradiation of the whole pelvis, followed by an additional 20 Gy with shielding and internal irradiation with an RALS. When lymph node metastasis was present, the nodes were irradiated with 40-50 Gy. The mean age of the 38 patients with CIN III was 45.2 years old, and they were para 0-4. In 24 (63.2%) of them the cancer was detected by cytodiagnosis as part of screening. Radical hysterectomy, simple hysterectomy, and conization were performed in 25 patients, 7 patients, and 6 patients, respectively. No recurrences have been detected, and the survival rate is 100%. The mean age of the 53 patients with cervical cancer stage I-IV was 62.4 years old, and they were para 0-10. There were 25 patients with stage I disease, 15 patients with stage II disease, 6 patients with stage III, and 7 patients with stage IV, and their 5-year survival rate was 82.4%, 68.8%, 66.7%, and 42.9%, respectively. Radioenteritis and radiocystitis occurred as adverse radiation effects. Pathologic factors influencing lymph node metastasis were examined by a multivariate analysis based on the data from 25 patients with stage I and II who underwent hysterectomy. The results of the analysis indicated the importance of screening and the choice of appropriate surgical method/technique, as well as the need for further investigation to determine the effective

    Purpose: The importance of human papilloma virus (HPV) infection in the outcome of cervical cancer after radiotherapy remains unknown. Our study explored whether the HPV status of tumors is associated with the outcome of radiotherapy in patients with cervical cancer. Methods and materials: A total of 84 patients with cervical cancer (6 Stage I, 10 Stage II, 49 Stage III, and 19 Stage IV) who underwent definitive radiotherapy between January 1995 and June 2000 were included in this study. Tumor samples were obtained from all patients by punch biopsy before radiotherapy. The presence of HPV and its type were analyzed by polymerase chain reaction (PCR) based assay using the consensus primers for E6 and L1 regions. Actuarial methods were used to calculate overall survival and disease-free survival. Results: A total of 42 patients (50%) had cancer recurrence after radiotherapy. HPV-positive tumors were found in 76.2% (64 cases) of patients. HPV-negative patients survived for significantly shorter time periods compared to the HPV-positive patients in the overall survival (p=0.007) and the disease-free survival (p=0.005). According to multivariate analysis, HPV status is a significant predictor of both overall (p=0.02) and disease-free survival time (p=0.005). Conclusion: The results of this study suggest that HPV-negative patients with cervical carcinoma have a significantly poorer prognosis after radiotherapy, and HPV status may be used as a marker to optimize the treatment of patients with this type of cancer

    Objective: Dose prescription and definition of target volume in brachytherapy of cervical and endometrial cancer are calculated to standard points as Manchester point A or point My(ometrium) in most centers. Calculation of doses to organs at risk mainly relies on ICRU-report 38. But standard dose prescription neglects individual patient anatomy. While MRI and CT had widespread impact on individual planning in external beam radiotherapy, there is still a minor influence on brachytherapy. The impact of individual anatomy on dose distribution in target volume and organs at risk demonstrates the objective of individual brachytherapy planning. Materials and Methods: 8 patients with cervical and 4 patients with endometrial carcinoma underwent MRI of the pelvis with in-situ applicators (ring-tandem applicators for cervical carcinoma and modified Heyman-capsules for endometrial carcinoma). T1w slices were angulated coronal and sagittal to get rectangular reproductions to applicator axis. Orthogonal or isocentric X-ray films for conventional treatment planning were done. MRI-information on target and organs at risk was transformed into coordinates relative to applicator axis and dose calculation on the database of conventional treatment planning was performed by Nucletron Planning System PLATO. Isodoses were projected into MRI slices. Prescribed dose to patients with cervical cancer was 8.5 Gy to point A resp. 10 Gy to point My (2cm below fundal myometrium and 2cm lateral applicator axis) in endometrial cancer. Results: Dose prescription to Manchester point A or point My represented in only 50% of cases uterine serosa. Instead of 2cm lateral of applicator axis, uterine surface ranged from 1.0 cm to 3.9 cm at the level of point A (mean 2.25 cm coronal and 1.77 cm sagittal) and from 1.5 cm to 4.4 cm at the level of point My (mean 2.7 cm coronal and 2.1 cm sagittal). Uterine volume ranged from 69 cc to 277 cc, mean volume was 150cc. Dose-volume histograms of patients with

    The authors previously presented a study of the accuracy of CT in the staging of bronchogenic carcinoma by means of correlative lymph node mapping and sampling in 85 patients. This study has now been extended to include 143 patients. Abnormal nodes (greater than or equal to 1 cm) were localized according to the ATS classification of regional lymph node mapping. One hundred thirty-eight patients underwent mediastinoscopy and 116, thoracotomy. In each case, lymph node groups 2R, 4R, 2L, 4L (paratracheal), 7 (subcarinal), and 5 (aorticopulmonary) underwent biopsy on the appropriate sides. Hilar nodes were resected with the surgical specimen. A total of 554 nodes were sampled. Overall sensitivity of CT for all the lymph node groups was similar to the previous study and was 40.5% with a specificity of 84.2%. Sensitivity was highest for group 5 (83%), and lowest for the subcarinal area (25%) (group 7). Specificity ranged from 71% for 10R hilar nodes to 90% for the subcarinal nodes. The positive predictive value was 34% and the negative predictive value was 87%. This study corroborates the authors' previous results and shows that when careful correlation of individual lymph nodes groups identified on CT is done with those sampled at surgery, the accuracy of CT in staging bronchogenic carcinoma is limited

    Objective: To discuss the clinical therapeutic effect and side reaction of superselective uterine arterial chemoembolization therapy for the treatment of cervical cancer. Methods: Bilateral uterine arterial chemoembolization was performed in 33 patients with pathologically-proved cervical cancer. The infusion drugs included DDP or L-OHP, EADM, MMC and 5-Fu. The Gelfoam particle was employed as embolic agent. The therapeutic effect evaluated by observing the improvement of clinical symptoms and the volume reduction of the tumor. Results: Of the total 33 patients with pathologically-confirmed cervical cancer, squamous cell carcinoma was seen in 29 and adenocarcinoma in 4. Based on FIGO classification (established by Federation International of Gynecology and Obstetrics), 6, 23 and 4 patients were classified in stage Ⅰ, Ⅱ and Ⅲ respectively. The angiography conducted during the procedure showed that the uterine arteries were markedly dilated, and spiral tumor-feeding arteries as well as tumor stain were also observed. Technical success together with perfect chemoembolization was achieved for 57 uterine arteries in 33 patients. Among the 33 patients, the interventional treatment was carried out three times in 2, two times in 2 and single time in 29. One week after the initial interventional procedure the remission rate of the clinical symptoms was 96% for squamous cell carcinoma and 100% for adenocarcinoma. One month after the treatment, the mean tumor volume was decreased by 30%, the tumor volume reduction for squamous cell carcinoma was 27.6% and was 50.0% for adenocarcinoma. Surgical resection after interventional therapy was carried out in 21 cases and additional radiotherapy after surgery or interventional procedure was adopted in 11 cases. The main adverse reactions after interventional procedure included fever, leucocytopenia, nausea, vomiting, abdominal pain, etc. Conclusion: Superselective uterine arterial chemoembolization is one of effective

    The aim of this retrospective study was to evaluate the contribution of 18 F-FDG PET to the clinical management and survival outcome of patients suspected of recurrent cervical carcinoma and in line with the hypothesis that early diagnosis of recurrent cervical cancer may improve overall survival. A total of 40 patients underwent conventional imaging (CI) and FDG PET/CT for suspected cervical cancer. Clinical management decisions were recorded with CI and additional PET/CT. Discordances and concordances between CI and PET/CT results were compared to the final diagnosis as based on histopathology analysis or follow-up considered as the gold standard. The final diagnosis was established pathologically (n=25) or by median clinical follow-up for 48 months after the PET (n=15). The PET/CT was positive in 76% (20/26) of patients compared to 19% (6/26) with CI. Globally PET/CT modified the treatment plan in 55% (22/40) of patients and in 75% (18/24) when the CI was negative prior to PET/CT. These changes led to the use of previously unplanned therapeutic procedures in 37.5% (15/40). When FDG PET was positive for recurrence (>3 foci), the median overall survival was 12 months (2-70) compared to patients with PET findings with ≤1 focus for which the median survival was not attained (p=0.007). A multivariate analysis of prognostic factors demonstrated that abnormal FDG uptake (>3 foci) was the most significant factor (p<0.03) for death from cervical cancer. FDG PET is a valuable tool in the case of suspected recurrence of cervical cancer on account of its impact on treatment planning and especially in predicting patient outcome. (orig.)

    Full Text Available Abstract Background While the association of human papillomavirus (HPV with cervical cancer is well established, the influence of HIV on the risk of this disease in sub-Saharan Africa remains unclear. To assess the risk of invasive cervical carcinoma (ICC associated with HIV and HPV types, a hospital-based case-control study was performed between September 2004 and December 2006 in Kampala, Uganda. Incident cases of histologically-confirmed ICC (N=316 and control women (N=314, who were visitors or care-takers of ICC cases in the hospital, were recruited. Blood samples were obtained for HIV serology and CD4 count, as well as cervical samples for HPV testing. HPV DNA detection and genotyping was performed using the SPF10/DEIA/LiPA25 technique which detects all mucosal HPV types by DEIA and identifies 25 HPV genotypes by LiPA version 1. Samples that tested positive but could not be genotyped were designated HPVX. Odds ratios (OR and 95% confidence intervals (CI were calculated by logistic regression, adjusting for possible confounding factors. Results For both squamous cell carcinoma (SCC and adenocarcinoma of the cervix, statistically significantly increased ORs were found among women infected with HPV, in particular single HPV infections, infections with HPV16-related types and high-risk HPV types, in particular HPV16, 18 and 45. For other HPV types the ORs for both SCC and adenocarcinoma were not statistically significantly elevated. HIV infection and CD4 count were not associated with SCC or adenocarcinoma risk in our study population. Among women infected with high-risk HPV types, no association between HIV and SCC emerged. However, an inverse association with adenocarcinoma was observed, while decrease in CD4 count was not associated with ICC risk. Conclusions The ORs for SCC and adenocarcinoma were increased in women infected with HPV, in particular single HPV infections, infections with HPV16- and 18-related types, and high-risk HPV types

AJCC utilizes a primary tumor, lymph node, metastasis (pTNM cancer staging approach.Objective: We wanted to determine if the AJCC pTNM carcinoma staging system identified patients with highly aggressive carcinoma of the eyelid. We also wanted to determine if there were any unexpected issues in its practical application. Design: We conducted a 15-year, consecutive, retrospective review of all cases of excisional biopsy for carcinoma of the eyelid. We reviewed the original histopathology slides and complete pathology records for each case.Results: Over a 15-year review period, 52 cases of excisional biopsy for carcinoma of the eyelid were identified. The average age of the study population was 72 years. Nodular well-differentiated basal cell carcinoma (BCC was the predominant histology for 85% of cases. Morpheaform/metatypical BCC was the next dominant at 9%. Squamous cell carcinoma and sebaceous carcinoma followed at 4% and 2%, respectively. We were able to assign clear staging to 50 of the 52 cases with the available pathology data. The stage results were as follows: stage 1A 72%, stage 1B 22%, stage II 4%, stage III 2%, with no cases of stage IV metastatic disease.Conclusions: The 7th edition AJCC Carcinoma of the Eyelid chapter proved to be a practical tool for carcinoma staging of the eyelid. The largest tumor dimension remains an effective predictive factor. High-grade pathologic prognostic factors such as tumor necrosis or perineural spread had a 100% association with a final stage of II or greater. Concordance and compliance was 100% for the recommended site

    Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-year overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity

    Purpose: Patients with advanced cervical cancer and highly hypoxic primary tumors show increased frequency of locoregional treatment failure and poor disease-free and overall survival rates. The potential usefulness of gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA)-based dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in assessing tumor hypoxia noninvasively was investigated in the present preclinical study. Methods and Materials: CK-160 and TS-415 human cervical carcinoma xenografts transplanted intramuscularly (i.m.) or subcutaneously (s.c.) in BALB/c nu/nu mice were subjected to DCE-MRI and measurement of fraction of radiobiologically hypoxic cells. Tumor images of K trans (the volume transfer constant of Gd-DTPA) and v e (the extracellular volume fraction of the imaged tissue) were produced by pharmacokinetic analysis of the DCE-MRI data. Fraction of radiobiologically hypoxic cells was measured by using the paired survival curve method. Results: Fraction of radiobiologically hypoxic cells differed significantly among the four tumor groups. The mean values ± SE were determined to be 44% ± 7% (i.m. CK-160), 77% ± 10% (s.c. CK-160), 23% ± 5% (i.m. TS-415), and 52% ± 6% (s.c. TS-415). The four tumor groups differed significantly also in K trans , and there was an unambiguous inverse relationship between K trans and fraction of radiobiologically hypoxic cells. On the other hand, significant differences among the groups in v e could not be detected. Conclusions: The study supports the clinical development of DCE-MRI as a method for assessing the extent of hypoxia in carcinoma of the cervix

    To determine the frequency of tuberculous cervical lymphadenopathy mimicking metastasis from papillary thyroid cancer. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from March 2005 to March 2010. Methodology: All patients above 12 years of age of either gender diagnosed on investigations as papillary thyroid cancer (PTC) were included in the study. Ultrasound and fine needle aspiration cytology (FNAC), neck of solitary thyroid nodules (STN) and cervical lymph nodes were done. Total thyroidectomy and excision biopsy of cervical lymph nodes was performed, histopathological results were recorded and patients were managed accordingly. Results: A total of 55 patients had PTC and 25 had cervical lymphadenopathy. Eighteen patients of PTC with cervical lymphadenopathy were diagnosed after investigations as cases of tuberculous cervical lymphadenopathy (TCL) initially considered as metastasis from PTC; 5 patients had metastasis from PTC. Two patients proved to be of reactive hyperplasia which initially showed tuberculous cervical lymphadenopathy on FNAC. So 80% patients of cervical lymphadenopathy with PTC were due to benign disease and 20% had metastasis in lymph node due to PTC. Conclusion: PTC with cervical lymphadenopathy due to co-existent tuberculosis is common. Metastasis from PTC in lymph nodes were less common than tuberculous lymphodenitis in this study. Tuberculosis should be considered before deciding for neck dissection in cases of PTC. (author)

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 μm. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author)

    Background: in advanced vaginal recurrences of cervical and endometrial carcinomas therapeutic options are rare because of preceding therapy. Patients and methods: 23 patients developing advanced vaginal recurrences of cervical and endometrial carcinomas were included. 15 patients started with external-beam therapy to the pelvis and eight patients after preceding radiotherapy underwent brachytherapy alone. All patients had ultrasound-guided implantation of transvaginal or transperineal interstitial needles for brachytherapy. Median prescribed total dose was 64 Gy. Results: 18 patients (78%) achieved complete remission. Six patients are alive without tumor and one with tumor after a median follow-up of 64 months. 14 patients died of tumor and two of intercurrent disease. 5-year disease-specific survival and local control rate were 43% and 47%, respectively, in patients with complete remission. Univariate analysis found time to relapse > 2 years, initial diameter {<=} 4 cm, initial volume < 15 cm{sup 3}, no extension to the pelvic side wall, volume before brachytherapy < 7.5 cm{sup 3}, brachytherapy coverage index > 0.8, and prescribed total dose > 64 Gy being positive predictors for local control and survival. Conclusion: the use of ultrasound guidance for placement of interstitial needles in template-based brachytherapy of advanced recurrent gynecologic malignancies is a feasible, safe, and cheap method with encouraging results. Today, ultrasound imaging can be also used to some extent for treatment planning which requires further development. Patient- and treatment-related prognostic factors can be defined. (orig.)

    Purpose: To retrospectively investigate whether postoperative low-pelvic radiotherapy (RT) is an appropriate treatment for node-negative, high-risk Stage I-IIA cervical cancer patients. Methods and Materials: A total of 228 Stage I-IIA cervical cancer patients treated by radical surgery and postoperative RT were included in this study. All patients had histopathologically negative pelvic node metastasis, but at least one of the following risk factors: parametrial involvement, positive or close resection margins, invasion depth two-thirds or greater cervical stromal thickness. Seventy-nine patients (35%) received 30-50 Gy (median 44) to whole pelvis and a boost dose to the low pelvis (whole-pelvic RT group); the other 149 patients (65%) received low-pelvic RT only (low-pelvic RT group). For both groups, the total external RT dose to the low pelvis ranged from 40 to 60 Gy (median 50). The potential factors associated with survival, small bowel (gastrointestinal) complications, and leg lymphedema were analyzed, and patients who had a relapse in the upper pelvis were identified. Results: The 5-year overall and disease-specific survival rate was 84% and 86%, respectively. After multivariate analysis, only bulky tumor (≥4 cm) and non-squamous cell carcinoma were significantly associated with survival. Parametrial involvement, lymph-vascular invasion, ≤50.4 Gy to the low pelvis, positive or close margins, and low-pelvic RT alone did not significantly affect survival. Grade I-V small bowel complications occurred in 33 patients (15%). Whole pelvic RT and >50.4 Gy to the low pelvis, but not old age and treatment technique (AP-PA vs. box), were significantly associated with gastrointestinal complications. Three patients (2%) in the low-pelvic RT group and 6 patients (8%) in the whole-pelvic RT group were found to have Grade III or higher small bowel complications (p=0.023). Thirty-one percent of patients developed lymphedema of the leg. A dose to the low pelvis >50.4 Gy

    Full Text Available This study aimed to determine the correlation between the volumetric parameters derived from the images of the second, third, and fourth cervical vertebrae by using cone beam computed tomography with skeletal maturation stages and to propose a new formula for predicting skeletal maturation by using regression analysis. We obtained the estimation of skeletal maturation levels from hand-wrist radiographs and volume parameters derived from the second, third, and fourth cervical vertebrae bodies from 102 Japanese patients (54 women and 48 men, 5–18 years of age. We performed Pearson’s correlation coefficient analysis and simple regression analysis. All volume parameters derived from the second, third, and fourth cervical vertebrae exhibited statistically significant correlations (P<0.05. The simple regression model with the greatest R-square indicated the fourth-cervical-vertebra volume as an independent variable with a variance inflation factor less than ten. The explanation power was 81.76%. Volumetric parameters of cervical vertebrae using cone beam computed tomography are useful in regression models. The derived regression model has the potential for clinical application as it enables a simple and quantitative analysis to evaluate skeletal maturation level.

    The purpose of this study was to determine the clinical value of a semiquantitative measure of human papillomavirus viral load by the hybrid capture 2 assay for stratification of the risk of histologic cervical intraepithelial neoplasia grade 3 or carcinoma. The Atypical Cells of Unknown Significance and Low-Grade Squamous Intraepithelial Lesions Triage Study was a randomized clinical trial of 5060 women with 2 years of follow-up to evaluate treatment strategies for women with equivocal or mildly abnormal cervical cytologic condition. The usefulness of the continuous hybrid capture 2 output relative light units/positive controls that were above the positive threshold (1.0 relative light units/positive controls), which was a surrogate for human papillomavirus viral load, for distinguishing between hybrid capture 2 positive women who were diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma during the study from those who were not diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma was examined with the use of receiver-operator characteristic analyses. Relative light units/positive controls values did not further discriminate between hybrid capture 2 positive women with cervical intraepithelial neoplasia grade 3 or carcinoma from those with less than cervical intraepithelial neoplasia grade 3 or carcinoma. The use of a cervical intraepithelial neoplasia grade 2 or more severe or carcinoma case definition did not alter our findings. Among women with atypical cells of unknown significance or low-grade squamous intraepithelial lesion cervical cytologic findings, the hybrid capture 2 viral load measurement did not improve the detection of 2-year cumulative cases of cervical intraepithelial neoplasia grade 3 or carcinoma significantly.

    Full Text Available Aim: Our aim is to detect the incidence and rate of high risk HPV-DNA in patients with cervical cancer,HGSIL,LGSIL or ASCUS and compare those findings with patients presenting with totally benign servical smears as well as to search for the factors influencing these rates. Materials and Methods: 85 patients with cytologic and histologic proven cervical carcinoma, HGSIL, LGSIL, ASCUS and 178 patients with totally benign (normal or infecton smear results as a control group who attented to Atatürk Training and Research Hospital 3rd Obstetrics and Gynecology Clinics between the dates of January 2006- July 2008 were included to our study. Within these patients age, first sexual intercourse, age, smoking habit, number of sexual partners, age of menarche and contraception methods were recorded. Pap smears and smears for detection of high risk HPV were taken concurrently from cervical transformation zone and external cervical ostium and the incidence of high risk HPV-DNA were examined. Results: High risk HPV DNA rate was detected as 65.2% positive in cervical carcinoma patients in our study. High risk HPV-DNA was positive in 54.8% of patients with HGSIL while it was positive in 25% of patients with LGSIL. High risk HPV-DNA was positive in 5% of patients with benign cervical cytology results. Discussion: The positivity rates of high risk HPV-DNA results in cervical carcinoma, HGSIL, LGSIL patients and in patients with benign cervical cytologies were statistically significant. When the age of menarche and contraception method were considered the HPV-DNA positivity rates’ differences were statistically insignificant.The differences for the age of first sexual intercourse, number of sexual partners, age and smoking habits were statistically significant.

    2016-07-01

    Full Text Available Cervical cancer is the fourth type of women neoplasia, with thousands of new cases annually. It is closely related to human papillomavirus (HPV infection, which has more than 13 oncogenic types, among them HPV 16 and 18 are implicated in 70% of cervical carcinoma cases. Alkaloids are nitrogenated and naturally occurring compounds, showing several uses in medical treatment, including cytotoxic and antineoplastic activities. In this work we aim to evaluate the cytotoxic and chemotherapeutic potential of alkaloids against cervical cancer. In order to accomplish this purpose, we have made a survey of potentially effective alkaloids with cytotoxic activities over HPV-16+ and HPV-18 + cells (HeLa cells. Through a literature review between the years of 1980 and 2015, we described the major alkaloid sources, distribution in nature and also discussed the mechanisms of action for their cytotoxicity. We found that alkaloids showed efficacy as cytotoxic agents, inhibiting cell growth of the HPV-transformed cells in vitro and in vivo by means of activation of intrinsic and extrinsic pathways of apoptosis, which included the clivage of caspases and PARP-1 (Poli-Adenosyl- Ribose Protease 1, increase in p53 expression, release of cytochrome C and increase of cell death receptors expression like Fas, mainly observed in HeLa (HPV- 18 + cell lines. Moreover, these secondary metabolites helped in modulating the MDR (Multi-Drug Resistance against the cell lines studied, which lead us to suggest their possible use as chemotherapeutic agents on the lesions caused by these virusesKeywords: Cervical cancer.

    Purpose: To identify prognostic factors for local and distant relapse and perform risk stratification for patients with advanced cervical cancer treated with radiotherapy (RT) alone. Methods and Materials: A total of 1031 patients with Stage IB-IVA squamous cell carcinoma of the cervix treated with full-course RT but without any chemotherapy were included for analysis. Of these, 311 patients with nonbulky Stage IB-IIA disease were designated the reference group and the other 720 patients were the study group. The associations of stage, squamous cell carcinoma antigen (SCC-ag) level, hemoglobin level, age, cell differentiation, and pelvic lymph node status with treatment failure were evaluated. The independent prognostic factors were identified by multivariate analysis. The study group was further stratified into subgroups using combinations of these risk factors. Results: In the study group, independent risk factors for local relapse were advanced stage and age 2, and positive pelvic lymph nodes. The 5-year distant relapse-free survival rate was 83% for patients with bulky Stage IB-IIA and IIB disease, SCC-ag level 2, and positive lymph nodes. Conclusion: The risk of treatment failure in advanced-stage cervical cancer patients treated by RT alone can be more precisely predicted by risk stratification. A certain subgroup of patients had better control than the others. The benefit of treating these relatively low-risk patients with additional treatment such as concurrent chemotherapy should be further evaluated in prospective studies or meta-analyses

    In the years 1948-1967 8275 patients with cervical carcinoma in various grades of progression were treated at the Institute of Oncology in Warsaw by radiotherapy from external fields. Five-year survival without signs of recurrence was obtained in 4204 cases, 3863 of them were irradiated from external fields with X-rays under conventional conditions, while 341 received Co/sup 60/ radiotherapy. In 43 patients treated with X-rays and radium and regarded as cured radiological evidence of femoral neck fracture was obtained. These patients account for 1.1% of all cured patients. In the group treated with Co/sup 60/ radiation in only 1 case femoral neck fracture was observed (0.3%). In the group of cured patients with femoral neck fracture the method of irradiation from external fields, the age, clinical course, radiological appearance of radiation-induced changes and the method of fracture management were analysed.

    Full Text Available OBJECTIVES: Precancerous and cancerous cells can trigger an immune response that may limit tumor development and can be used as a prognostic marker. The aims of the present study were to quantify the presence of B and T lymphocytes, macrophages and cells expressing inducible nitric oxide synthase (iNOS in the cervical stroma of women with grade III cervical intraepithelial neoplasia (CIN III or in the intratumoral and peritumoral tissue of women with stage I invasive carcinoma. METHODS: Cervical tissue specimens were obtained from 60 women (20 each from control tissues, CIN III and invasive carcinomas. The average ages in the control, CIN III and invasive groups were 43.9 (± 4.3, 35.5 (± 9.5, and 50 (± 11.2 years, respectively. The specimens were immunohistochemically labeled with antibodies to identify T lymphocytes (CD3, cytotoxic lymphocytes (CD8, B lymphocytes (CD20, macrophages (CD68 and iNOS. We evaluated the markers in the stroma above the squamocolumnar junction (control, at the intraepithelial lesion (CIN cases, and in the nfiltrating tumor. Two independent observers performed the immunohistochemical analysis. RESULTS: T lymphocytes, B lymphocytes, macrophages and iNOS were present more frequently (P<0.05 in the stroma of peritumoral invasive tumors compared to the controls and intratumoral invasive cancer samples. CD3+ and CD20+ lymphocytes were present more frequently in CIN III patients compared to samples from patients with intratumoral invasive cancer (P<0.05. CONCLUSION: High numbers of T and B lymphocytes, macrophages and iNOS-expressing cells in the peritumoral stroma of the invasive tumors were observed. Cell migration appeared to be proportional to the progression of the lesion.

    Hydroxyurea was evaluated as a possible radiation sensitizer in 130 evaluable women with Stages IIB and IIIB (International Federation of Gynecology and Obstetrics) carcinoma of the uterine cervix. This was a prospective double-blind randomized study in which hydroxyurea or placebo was compared in conjunction with continuous or split-course radiation therapy. Of all patients with Stage IIB cancer without biopsy proof of aortic node metastasis, a significant improvement in survival (P < 0.01) was achieved in the hydroxyurea group (74.0 per cent) as compared to the patients receiving placebo (43.5 per cent). In women with Stage IIIB cervical cancer there was a trend toward longer survival in those receiving hydroxyurea (52.1 per cent) as compared to those receiving placebo (33.3 per cent). However, there was a statistically significant improvement in survival in those women with Stage IIIB cervical cancer who had staging done at operation, were found to have negative para-aortic nodes, and subsequently received continuous radiation therapy (90.9 per cent) as compared to those receiving split-course therapy (29.4 per cent)

    Full Text Available ABSTRACT Objectives: To evaluate the cephalometric changes in skeletal, dentoalveolar and soft tissue variables induced by Clark's Twin Block (CTB in Class II, Division 1 malocclusion patients and to compare these changes in different cervical vertebral maturation stages. Methods: Pre- and post-treatment/observation lateral cephalograms of 53 Class II, Division 1 malocclusion patients and 60 controls were compared to evaluate skeletal, dentoalveolar and soft tissue changes. Skeletal maturity was assessed according to cervical vertebral maturation stages. Pre- and post-treatment/observation mean changes and differences (T2-T1 were compared by means of Wilcoxon sign rank and Mann-Whitney U-tests, respectively. Intergroup comparisons between different cervical stages were performed by means of Kruskal-Wallis test and Mann-Whitney U-test (p ≤ 0.05 . Results: When compared with controls, there was a significant reduction in ANB angle (p < 0.001, which was due to a change in SNB angle in CS-2 and CS-3 (p < 0.001, and in SNA (p < 0.001 and SNB (p = 0.016 angles in the CS-4 group. There was significant increase in the GoGn-SN angle in CS-2 (p = 0.007 and CS-4 (p = 0.024, and increase in Co-Gn and Go-Gn amongst all cervical stages (p < 0.05. There was significant decrease in U1-SN and increase in IMPA amongst all cervical stages (p < 0.05. There was significant retraction of the upper lip in CS-3 (p = 0.001, protrusion of the lower lip in CS-2 (p = 0.005, increase in nasolabial angle in CS-4 (p = 0.006 and Z-angle in CS-3 (p = 0.016, reduction in H-angle in CS-2 (p = 0.013 and CS-3 (p = 0.002 groups. When pre- and post-treatment mean differences were compared between different cervical stages, significant differences were found for SNA, SNB and UI-SN angles and overjet. . Conclusions: The Twin-Block along with the normal craniofacial growth improves facial esthetics in Class II, Division 1 malocclusion by changes in underlying skeletal and

    FDG-PET/CT imaging has an emerging role in staging and treatment planning of various tumor locations and a number of literature studies show that also the carcinoma of the anal canal may benefit from this diagnostic approach. We analyzed the potential impact of FDG-PET/CT in stage definition and target volume delineation of patients affected by carcinoma of the anal canal and candidates for curative radiotherapy. Twenty seven patients with biopsy proven anal carcinoma were enrolled. Pathology was squamous cell carcinoma in 20 cases, cloacogenic carcinoma in 3, adenocarcinoma in 2, and basal cell carcinoma in 2. Simulation was performed by PET/CT imaging with patient in treatment position. Gross Tumor Volume (GTV) and Clinical Target Volume (CTV) were drawn on CT and on PET/CT fused images. PET-GTV and PET-CTV were respectively compared to CT-GTV and CT-CTV by Wilcoxon rank test for paired data. PET/CT fused images led to change the stage in 5/27 cases (18.5%): 3 cases from N0 to N2 and 2 from M0 to M1 leading to change the treatment intent from curative to palliative in a case. Based on PET/CT imaging, GTV and CTV contours changed in 15/27 (55.6%) and in 10/27 cases (37.0%) respectively. PET-GTV and PET-CTV resulted significantly smaller than CT-GTV (p = 1.2 × 10 -4 ) and CT-CTV (p = 2.9 × 10 -4 ). PET/CT-GTV and PET/CT-CTV, that were used for clinical purposes, were significantly greater than CT-GTV (p = 6 × 10 -5 ) and CT-CTV (p = 6 × 10 -5 ). FDG-PET/CT has a potential relevant impact in staging and target volume delineation of the carcinoma of the anal canal. Clinical stage variation occurred in 18.5% of cases with change of treatment intent in 3.7%. The GTV and the CTV changed in shape and in size based on PET/CT imaging

    The aim of our study was to investigate and evaluate the prognostic value of and correlations between preclinical and clinical factors such as the stage of the disease, blood Hb level before treatment, size of cervix and lymph nodes evaluated by CT, age, dose of irradiation and duration of radiotherapy related to overall survival, disease-free survival, local control and metastases-free survival in cervical cancer patients receiving radiotherapy alone. 162 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIA-IIIB cervical carcinoma treated with irradiation were analysed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. The Hb level before treatment showed significant influence on overall survival (p = 0.001), desease free survival (p = 0.040) and local control (p = 0.038). The lymph node status (>10 mm) assessed on CT had impact on overall survival (p = 0,030) and local control (p = 0,036). The dose at point A had impact on disease free survival (p = 0,028) and local control (p = 0,021) and the radiotherapy duration had showed significant influence on overall survival (p = 0,045), disease free survival (p = 0,006) and local control (p = 0,033). Anemia is a significant and independent prognostic factor of overall survival, disease-free survival and local control in cervical cancer patients treated with irradiation. The size of lymph nodes in CT is an independent prognostic factor for overall survival and local control in cervical cancer patients. The size of cervix uteri evaluated by CT has no prognostic significance in cervical cancer patients treated with radiotherapy. The prognostic value of FIGO stage of cervical cancer is influenced by other factors, analyzed in this study and is not an independent prognostic factor

    Endometrial carcinoma is the most common gynaecologic malignancy in industrialised countries and the incidence is still rising. Primary treatment is based on preoperative risk classification and consists in most cases of hysterectomy with bilateral salpingo-oophorectomy. In patients with serous and clear cell histology a complete surgical staging is mandatory. However, in routine clinical practice final histology regularly does not correspond with the preoperative histological diagnosis. This results in both over and under treatment. The aim of this multicentre, prospective cohort study is to select a panel of prognostic biomarkers to improve preoperative diagnosis of endometrial carcinoma in order to identify those patients that need extended surgery and/or additional treatment. Additionally, we will determine whether incorporation of cervical cytology and comorbidity could improve this preoperative risk classification. All patients treated for endometrial carcinoma in the participating hospitals from September 2011 till December 2013 are included. Patient characteristics, as well as comorbidity are registered. Patients without preoperative histology, history of hysterectomy and/or endometrial carcinoma or no surgical treatment including hysterectomy are excluded. The preoperative histology and final pathology will be reviewed and compared by expert pathologists. Additional immunohistochemical analysis of IMP3, p53, ER, PR, MLH1, PTEN, beta-catenin, p16, Ki-67, stathmin, ARID1A and L1CAM will be performed. Preoperative histology will be compared with the final pathology results. Follow-up will be at least 24 months to determine risk factors for recurrence and outcome. This study is designed to improve surgical treatment of endometrial carcinoma patients. A total of 432 endometrial carcinoma patients were enrolled between 2011 and 2013. Follow-up will be completed in 2015. Preoperative histology will be evaluated systematically and background endometrium will be

    Purpose: To compare the outcome for patients with squamous cell carcinoma of cervical lymph nodes metastatic from an unknown primary site who were irradiated to both sides of the neck and potential mucosal sites with opposed photon beams, and for those irradiated to the ipsilateral side of the neck alone with an electron beam. Methods and Materials: Fifty-two patients with squamous cell carcinoma metastatic to cervical lymph nodes from an unknown primary site were irradiated by two different methods. Thirty-six were irradiated with a bilateral technique (BT), i.e., to both sides of the neck, including the naso-oro-hypopharyngeal mucosa, and 16 were irradiated with an electron beam (EB) to the ipsilateral side of the neck alone. Twenty patients of the BT group and 11 of the EB group had cervical lymph node dissections, and the remaining 21 patients had lymph node biopsies, prior to radiotherapy. Results: Tumor control in the ipsilateral side of the neck did not differ for either radiation technique, but was significantly higher after lymph node dissection than after biopsy (90 vs. 48%; p = 0.0004). Control of subclinical metastases in the contralateral cervical lymph nodes was higher for patients irradiated with BT than for patients irradiated with EB (86 vs. 56%; p 0.03). The occult primary was later discovered in 8% of the patients in the BT group and 44% of the EB group (p = 0.0005). The disease-free survival rate at 5 years for patients who had lymph node dissection prior to irradiation was 61%, and was 37% for those who had biopsy (p = 0.05). Only 20% of patients who subsequently developed an occult primary were salvaged and survived for 5 years after salvage treatment. Conclusion: Bilateral neck and mucosal irradiation is superior to ipsilateral neck irradiation in preventing contralateral cervical lymph node metastases and the subsequent appearance of an occult primary cancer. Both techniques combined with cervical lymph node dissection were equally effective

    The occurrence of skeletal muscle metastases is a very rare event. Only two cases of late skeletal muscle recurrence from cervical cancer have been documented until now. A 38-year old patient, submitted to radical hysterectomy and pelvic lymphadenectomy for a squamous FIGO stage IB1 cervical carcinoma, presented after 76 months with a palpable, and painless swelling on the left hemithorax. MRI showed a nodule located in the context of the intercostal muscles. Pathology revealed the presence of metastasis of squamous cell carcinoma of similar morphology as the primary. On the basis of FDG-PET findings, which excluded other sites of disease, surgical excision of the lesion was performed. The patient was triaged to chemotherapy plus external radiotherapy. A case of skeletal muscle recurrence from cervical cancer after a very long interval from primary diagnosis is reported. Muscular pain or weakness, or just a palpable mass in a patient with a history of cancer has always to raise the suspicion of muscle metastasis

    Purpose: Our aim was to determine the efficacy of consolidation chemotherapy after concurrent chemoradiation (CCRT) using high-dose-rate brachytherapy in patients with locally advanced cervical carcinoma. Methods and Materials: Patients with cervical carcinoma (FIGO stage IB2-IVA) were treated with external beam radiation therapy to the whole pelvis (50.4 Gy) and high-dose-rate brachytherapy (24 Gy to point A). Cisplatin 60 mg/m 2 (Day 1) and 5-fluorouracil 1000 mg/m 2 (Days 1-5) were given every 3 weeks starting concurrently with the radiation and followed by 3 more cycles of consolidation for a total of 6 cycles. Results: Thirty patients (94%) received 3 more cycles of post-CCRT consolidation chemotherapy and were evaluable for the toxicity and efficacy of consolidation. The most common toxicities of Grade 2 or higher were nausea or vomiting (47%) and anemia (33%). Late complications of the rectum and bladder occurred in 13% and 6% of the patients, respectively. The clinical complete response rate was 87% (95% CI, 75%-99%). During a median follow-up of 27 months (range, 6-58 months), 5 patients (17%) had recurrence; the sites of failure were 3 (10%) inside the radiation field and 2 (7%) outside the radiation field. The estimated 3-year progression-free survival rate was 83% (95% CI, 67%-99%) and overall survival rate was 91% (95% CI, 79%-100%). Conclusions: Consolidation chemotherapy after CCRT is well tolerated and effective in patients with locally advanced cervical carcinoma. A prospective randomized trial to compare this treatment strategy with standard CCRT seems to be worthwhile

    Urinary tract complications apparently resulting from radiation therapy for carcinoma of the cervix can occur as long as 30 years after cessation of such treatment. Patients generally present with urinary incontinence and often are treated by standard operative methods that usually are unsuccessful. Incontinence is related to bladder fibrosis, urethral nonfunction and vesicovaginal fistuLa formation, and may be accompanied by bilateral ureteral obstruction. Of 11 patients with late complications of radiotherapy 4 had upper tract deterioration, 4 had vesicovaginal fistulas, 5 had an incompetent urethra aNd 9 had a fibrotic, noncompliant areflexive bladder. Treatment was aimed at providing adequate low pressure storage capacity and consisted of augmentation cystoplasty in 5 patients, repair of the fistula in 4 and correction of urethral dysfunction in 5. Women who complain of incontinence and/or irritable bladder symptoms with a history of radiotherapy for cervical carcinoma should be evaluated for fistuLa formation, urethral incompetence, and detrusor areflexia and fibrosis before treatment is done

    Full Text Available Epstein–Barr virus (EBV belongs to the group of gamma-herpes viruses and was the first recognized human oncovirus. EBV is responsible for infectious mononucleosis and multiple lymphoid and epithelial malignancies including B-cell lymphomas (Burkitt lymphoma, Hodgkin lymphoma, and post-transplant lymphoproliferative disorder, various T-cell/NK lymphoproliferative disorders, nasopharyngeal carcinoma, and gastric carcinoma, respectively. In addition, the presence of EBV has been documented in other cancers including breast, prostate, oral, and salivary gland carcinomas. The presence and role of EBV in cervical cancer and its precursor lesions (CIN have also been described, but the results from the literature are inconsistent, and the causal role of EBV in cervical cancer pathogenesis has not been established yet. In the present review, we briefly surveyed and critically appraised the current literature on EBV in cervical cancer and its variants (lymphoepithelioma-like carcinoma as well as its precursor lesions (CIN. In addition, we discussed the possible interactions between EBV and human papilloma virus as well as between EBV and immune checkpoint regulators (PD-L1. Though further studies are needed, the available data suggest a possible causal relationship between EBV and cervical cancer pathogenesis.

    Background: Significant antitumor activity has been reported with the combined use of 13-cis-retinoic acid (cRA) and interferon-α2a (IFN-α) in the treatment of advanced-stage cervical cancers and skin cancers. Since IFN-α has been shown to be a modest radiation enhancer for selected malignant tumor cells and the cytotoxic activity is more enhanced by combining cRA and IFN-α, we hypothesized that the exposure of selected human carcinoma cells to combined cRA and IFN-α would render the cells highly radiosensitive. Methods and Materials: Two human cervical carcinoma cell lines, ME-180 and HeLa-S3, were chosen for the present study because of the different characteristics of the retinoic acid receptor status of the cell lines. To demonstrate the effects of combined cRA and IFN-α treatment on radiation response, we exposed the cells to cRA, IFN-α, or a combination of the drugs for 72 h before radiation. Experiments were carried out at minimally cytotoxic concentrations of the drug for radiation studies. End points of the study were cell growth inhibition and clonogenic ability of the single-plated cells. Effects of cRA and IFN-α on radiation response were quantitatively analyzed by constructing the radiation cell survival curves of ME-180 and HeLa cells. Results: ME-180 cells exhibited varying degrees of cytotoxicity with cRA and IFN-α, while HeLa cells showed no toxic effects with the same treatment. Combined treatment of cRA and IFN-α produced an additive cytotoxic effect in ME-180 cells. Radiosensitization was minimal when ME-180 cells were treated with either cRA or IFN-α before radiation. When ME-180 cells were exposed to 10 μM cRA for 48 h and 1000 U/ml IFN-α for 24 h prior to radiation, there was a significant enhancement in radiation-induced cell killing; the dose modification factor was 2.1 ± 0.9 at the 1% cell-survival level. On the other hand, HeLa-S3 cells exhibited no increased cytotoxicity or radiation enhancement under the same experimental

    Objectives/hypothesis: Sarcomatoid carcinoma of head and neck mucosal sites is a rare malignancy surrounded with much controversy. One factor consistently reported yet not well supported throughout the literature is their relative radioresistance and a general belief that surgery is the treatment of choice. Our objective was to determine if patients treated with radiation for early glottic carcinoma with this histologic diagnosis had worse outcomes than typical squamous cell carcinoma of similar stage. Materials and Methods: Twenty-eight cases of early stage sarcomatoid carcinoma of the larynx treated with definitive doses of megavoltage irradiation between 1969 and 1995 at the University of Texas M.D. Anderson Cancer Center form the cohort for this analysis. All pathologic material was reviewed to confirm the diagnosis. Follow-up ranged from 1.5 - 24 years (median, 10 years). Results: Twenty-one patients were staged T1 and 7 patients had stage T2 disease. Sixteen tumors had the more typical polypoid morphology of sarcomatoid carcinoma. All patients were treated with small laryngeal fields, median size 20 cm2, and to a median dose of 65 Gy. Four patients (14%) had local disease recurrence. All 4 patients had salvage total laryngectomies and remained free of local disease. Only one patient manifested regional and distant disease. The 10-year actuarial survival rate was 63%. Conclusions: Patients with early staged sarcomatoid carcinoma of the glottis treated with radiation had similar control rates to irradiated patients with similar volume disease with the more typical squamous cell carcinoma. We do not believe that the histologic diagnosis of sarcomatoid carcinoma by itself should influence the decision to not treat a patient with early staged glottic disease with irradiation

    The aim of this study is to determine the differences in sexual life of women with cervical cancer after surgery and radiation therapy. A total of 210 patients treated for cervical cancer at the Department of Obstetrics and Gynecology, School of Medicine, University of Zagreb, Croatia between March 2001 and March 2003 were asked to fill in the questionnaire. Sexual life had worsened in 42.86% of the surgical patients, as had in 25.00% of irradiated patients (p 0.05)). More than 80% of patients didn't notice any changes in their partner's behavior. Almost every third woman felt certain change in her "body image", similar in both groups (p > 0.05). Need for consultations regarding sex life after diagnosis were recognized by 71.43% of patients. In conclusion we can say that considerable amount of attention should be given to psychological and sexual aspects of recovery of patients, because those aspects can significantly influence patients rehabilitation and prognosis.

    Locally advanced invasive cervical cancer [International Federation of Gynecology and Obstetrics (FIGO) IIB/III] is treated by chemoradiation. The response to treatment is variable within a given FIGO stage. Therefore, the aim of the present study was to evaluate the gene promoter methylation profile and corresponding transcript expression of a panel of six genes to identify genes which could predict the response of patients treated by chemoradiation. In total, 100 patients with invasive cervical cancer in FIGO stage IIB/III who underwent chemoradiation treatment were evaluated. Ten patients developed systemic metastases during therapy and were excluded. On the basis of patient follow-up, 69 patients were chemoradiation-sensitive, whereas 21 were chemoradiation-resistant. Gene promoter methylation and gene expression was determined by TaqMan assay and quantitative real-time PCR, respectively, in tissue samples. The methylation frequency of ESR1, BRCA1, RASSF1A, MLH1, MYOD1 and hTERT genes ranged from 40 to 70%. Univariate and hierarchical cluster analysis revealed that gene promoter methylation of MYOD1, ESR1 and hTERT could predict for chemoradiation response. A pattern of unmethylated MYOD1, unmethylated ESR1 and methylated hTERT promoter as well as lower ESR1 transcript levels predicted for chemoradiation resistance. Methylation profiling of a panel of three genes that includes MYOD1, ESR1 and hTERT may be useful to predict the response of invasive cervical carcinoma patients treated with standard chemoradiation therapy.

    A case of clear cell carcinoma of the endometrium following squamous cell carcinoma of the cervix is reported. The patient had had a previous cervical biopsy which revealed squamous cell carcinoma (large cell non-keratinizing type), classified clinically as a stage IIb lesion. She was treated with external pelvic irradiation delivering an estimated tumor dose of approximately 7,000 rads and intracavital radium application delivering 4,995 mg.hr.radiation when she was 51 years old. She complained of post-menopausal bleeding at age 66 and was diagnosed by endometrial cytology as having clear cell carcinoma of the endometrium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy and omentectomy were performed. The clinical stage of the endometrial cancer was Ib. She is alive after 2 years with no evidence of disease. Endometrial cytology revealed several adenocarcinoma cells in small clusters. The shape of the nuclei was somewhat irregular, the chromatin pattern was fine granular, and single or multiple nucleoli were seen. The diameter of these nuclei ranged from 10 to 30 {mu}m. The cytoplasm was pale green or vacuolated. The volume of the cytoplasm varied from scanty to abundant. These findings suggested clear cell carcinoma. Histopathologically, an irregular shaped polypoid tumor, 3 x 1.5 cm in size, was located on the lower anterior wall of the uterine corpus. The tumor was a clear cell carcinoma showing a solid and papillary pattern. A hobnail pattern was not observed. The cytoplasm was clear and abundant, and PAS-positive granules digestible by diastase were seen. These 2 cancers had different pathological features and their immunohistochemical reactivities for CEA and keratin were also different. The patient was regarded as having a rare heterochronous double cancer consisting of squamous cell carcinoma of the cervix and clear cell carcinoma of the endometrium. (author).

    The cervical vertebrae have been proposed as a method of determining biologic maturity. The purposes of this study were to establish a pattern of mandibular growth and to relate this pattern to the stages of cervical vertebral maturation. Cephalometric radiographs, taken annually from ages 9 to 18 years, were evaluated for 90 boys from the Burlington Growth Center, Toronto, Ontario, Canada. Mandibular lengths were measured from articulare to gnathion, and incremental growth was determined. Cervical vertebral maturation stages were assessed by using a 6-stage method. Advanced, average, and delayed maturation groups were established. The prepubertal mandibular growth minimum velocity occurred during cervical stages 1 through 4 (P = 0.7327). Peak mandibular growth velocity occurred most frequently during stage 4 in all 3 maturation groups, with a statistical difference in the average and delayed groups (P cervical stages 1 through 6 does not occur annually; time spent in each stage varies depending on the stage and the maturation group. Cervical vertebral maturation stages cannot accurately identify the mandibular prepubertal growth minimum and therefore cannot predict the onset of the peak in mandibular growth. The cervical vertebral maturation stages should be used with other methods of biologic maturity assessment when considering both dentofacial orthopedic treatment and orthognathic surgery.

    The purpose of this study was to evaluate the results of medium-dose-rate (MDR) intracavitary brachytherapy (ICRT) for cervical cancer. Between May 1991 and March 2001, 80 patients with cervical cancer were treated with external radiotherapy combined with MDR-ICRT. Two patients were excluded from this study. The median age of patients was 61 years (range: 30-87 years). Seventy-five patients had pathologically proved squamous cell carcinoma, and 3 had adenocarcinoma. The patients were staged by Union Internationale Contre le Cancer (UICC) classification as follows: Stage IA (2), Stage IB (4), Stage IIA (5), Stage IIB (22), Stage IIIA (1), Stage IIIB (32), Stage IVA (5), Stage IVB (7). Median follow-up for survivor was 68 months (range: 12-131 months). The radiation therapy was based on a combination of ICRT and external pelvic irradiation. Patients with stages II, III and IVA were treated with whole-pelvic irradiation with respective total doses of 20, 30, and 40 Gy. Doses of 40, 30, 20, and 20 Gy parametrial irradiation were added with central shield pelvic irradiation for stages IB, II, III and IVA lesions respectively. For MDR-ICRT, from May 1991 to December 1995, point A dose were 40 Gy/4 fractions for stages I and II, 38 Gy/4 fractions for stage III, and 28.5 Gy/3 fractions for stage IVA. And from January 1996 to March 2001, point A dose of 36 Gy/4 fractions for stages I and II, 34 Gy/4 fractions for stage III, and 25.5 Gy/3 fractions for stage IVA. The median dose rate at point A was 1.7 Gy/hour (range: 1.3-2.2 Gy/hour). The 5-year cause-specific survival rates were 100%, 76%, 51% and 40% for stages I, II, III and IVA respectively. All patients with stage IVB died from the tumor with a median survival time of 12 months. The 5-year pelvic control rates were 100%, 88%, 69% and 40% for stages I, II, III and IVA respectively. Major late complications occurred in 2 patients (3%). One patient developed vesico- and recto-vaginal fistulae, and died of pelvic infection

    Marked progress has been made in surgery for esophageal carcinoma, however, when compared to results of surgery for other carcinomas of the digestive tract, much research remains to be done. The author transplanted VX2 carcinoma, a transplantable tumor of the rabbit, to the esophagus in attempt to determine the mode of metastases of esophageal carcinoma to lymph nodes and also to observe the effect of chemotherapy (Bleomycin) and radiotherapy (Betatron). Carcinoma of the cervical esophagus metastasized to the cervical lymph nodes and then to the paratracheal lymph nodes. Carcinoma of the upper thoracic esophagus metastasized to the paratracheal lymph nodes and then to the cervical lymph nodes. Carcinoma of the mid-thoracic esophagus metastasized to the intrathoracic lymph nodes and then to the intraperitoneal lymph nodes. Carcinoma of the abdominal esophagus metastasized to the intraperitoneal lymph nodes and then to the intrathoracic lymph nodes. Skipping metastasis was rarely observed. Carcinoma of the thoracic esophagus with metastases of lymph nodes in the cervical or abdominal portion was considerably advanced, therefore it is considered that cleaning of the intrathoracic lymph nodes and simultaneous chemotherapy are required when such cases are encountered clinically. Irradiation resulted in regression in the size of the tumor and metastases to lymph nodes and there was a decrease in metastases to the distant lymph nodes. Effects of irradiation were similar on tumors and lymph nodes with positive metastases located within the field of irradiation. Bleomycin medication resulted in regression in the size of tumor and metastases to lymph nodes. Effects of Bleomycin medication were similar on tumors and lymph nodes with positive metastases.

    Most non-screen-detected cervical cancers are advanced stage. We assess the potential for cytology to expedite diagnosis when used outside of routine call and recall screening for cervical cancer. Two cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40-69 at first cytology, and 14,668 women aged ≥70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ≥66 with and without cytology in the year prior to diagnosis. There were 259 cancers diagnosed in women aged 40-69 at first cytology, and 78 in women aged ≥70. The sensitivity of cytology ≥ HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355-462) and 226 (95% CI: 177-292) respectively. Women aged ≥66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17-22% reduction in case fatality. Cervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality. © The Author(s) 2015.

    Cervical cancer is the second most common cancer among women worldwide, with developing countries accounting for >80% of the disease burden. Although in the West, active screening has been instrumental in reducing the incidence of cervical cancer, disease management is hampered due to lack of biomarkers for disease progression and defined therapeutic targets. Here we carried out gene expression profiling of 29 cervical cancer tissues from Indian women, spanning International Federation of Gynaecology and Obstetrics (FIGO) stages of the disease from early lesion (IA and IIA) to progressive stages (IIB and IIIA–B), and identified distinct gene expression signatures. Overall, metabolic pathways, pathways in cancer and signaling pathways were found to be significantly upregulated, while focal adhesion, cytokine–cytokine receptor interaction and WNT signaling were downregulated. Additionally, we identified candidate biomarkers of disease progression such as SPP1, proliferating cell nuclear antigen (PCNA), STK17A, and DUSP1 among others that were validated by quantitative real-time polymerase chain reaction (qRT-PCR) in the samples used for microarray studies as well in an independent set of 34 additional samples. Integrative analysis of our results with other cervical cancer profiling studies could facilitate the development of multiplex diagnostic markers of cervical cancer progression

    The purpose of our study was to evaluate the capability of a subsecond spiral-CT scanner using two contrast medium phases in staging of colorectal cancer. In our study we included 37 patients with proven rectum or colon carcinoma. Spiral CT was performed following tap-water enema of the colon in the arterial and venous phases of contrast medium enhancement. Our results were compared with the findings of pathological examination after surgery. The tumor's size and extension were evaluated in the arterial and venous phases, the lymph nodes in the venous phase of the CT scan. The tumor was in the rectum (n = 14), sigma (n = 11), descending colon (n = 6), and cecum (n = 6). Two-phase spiral CT had a sensitivity of 97.2 % in the arterial phase and 89.1 % in the venous phase in detecting the carcinoma. The staging results were in the arterial phase in 30 of 37 cases (81.0 %) and in the venous phase in 24 of 37 cases (64.8 %) according to pathology. In 27 of 32 patients (84.3 %) lymph nodes were detected. The correct classification of the N-stage was possible in 23 of 34 cases (67.6 %). The combined use of arterial and venous phases in staging of colorectal cancer can improve the T- and N-stage classification in comparison with using only one contrast medium phase. The arterial phase is superior compared with the venous phase for local tumor staging and the venous phase is used for lymph node assessment. (orig.) (orig.)

    Purpose : To evaluate the efficacy of hydroxyurea with radiation in carcinoma of the cervix, huge exophytic or endophytic stage IIa and Iib. Materials and Methods : Sixty four patients with carcinoma of the cervix stage IIA(29 patients) with exophytic({>=}3cm in diameter) or huge endophytic mass and IIB(35 patients) treated with radiation and hydroxyurea at the Department of Radiation Oncology, Dongsan Hospital, Keimyung University, School of Medicine from Aug, 1989 to May, 1991. The maximum and mean follow up durations were 68 and 57 months respectively. The radiation therapy consisted of external irradiation to the whole pelvis(3600-5400cGy) shield (4X10 cm), and combined with intracavitary irradiation (3000-3500cGy to point A). Hydroxyurea was to be taken in a single oral dose of 1.0gm/day during radiation therapy. Results : The control rate was 89.1%. The actuarial overall five year survival rate was 78.8% for stage IIA and 72.8% for stage IIB. The overall recurrence rate was 25%(16/64). Twenty-three percent of the patients developed or greater thrombocytopenia. Grade 3 or greater GI, GU complication and anemia were not noted. There was no treatment related death noted. Conclusion : We considered that hydroxyurea and radiation therapy may improve survival rate in huge exophytic and endophytic stage IIa cervical carcinoma with acceptible morbidity.

    The aim was to determine the long-term prognosis in patients with stage IIIb-IVa squamous cell carcinoma of the cervix who were treated with intra-arterial neoadjuvant chemotherapy (NAC), and to analyze factors related to prognostic value. The authors assessed the disease-free survival of 21 patients with FIGO stage IIIb-IVa squamous cell carcinoma of the cervix treated with intra-arterial NAC followed by irradiation therapy. Before chemotherapy, five factors (age, clinical stage, histologic type, parametrial involvement and serum level of SCC) were evaluated for their correlation with disease-free survival. Univariate Cox's proportional hazard model also demonstrated that age was a significant prognostic factor as a continuous variable. Intra-arterial NAC thus appeared to be effective in treating older patients with stage IIIb-IVa squamous cell carcinoma of the cervix

    The elevated expression of vascular endothelial growth factor C (VEGF-C) is correlated with clinical cervical cancer metastasis and patient survival, which is interpreted by VEGF-C functions to stimulate angiogenesis and lymphatic genesis. However, the direct impact of VEGF-C on cervical cancer cell motility remains largely unknown. In this study, we investigated the effects of VEGF-C on actin cytoskeleton remodeling and on cervical cancer cell migration and invasion and how the actin-regulatory protein, moesin regulated these effects through RhoA/ROCK-2 signaling pathway. On cervical carcinoma cell line SiHa cells, exposure of VEGF-C triggered remodeling of the actin cytoskeleton and the formation of membrane ruffles, which was required for cell movement. VEGF-C significantly enhanced SiHa cells horizontal migration and three-dimensional invasion into matrices. These actions were dependent on increased expression and phosphorylation of the actin-regulatory protein moesin and specific moesin siRNA severely impaired VEGF-C stimulated-cell migration. The extracellular small GTPase RhoA/ROCK-2 cascade mediated the increased moesin expression and phosphorylation, which was discovered by the use of Y-27632, a specific inhibitor of Rho kinase and by transfected constitutively active, dominant-negative RhoA as well as ROCK-2 SiRNA. Furthermore, in the surgical cervical specimen from the patients with FIGO stage at cervical intra-epithelial neoplasia and I-II cervical squamous cell carcinoma, the expression levels of moesin were found to be significantly correlated with tumor malignancy and metastasis. These results implied that VEGF-C promoted cervical cancer metastasis by upregulation and activation of moesin protein through RhoA/ROCK-2 pathway. Our findings offer new insight into the role of VEGF-C on cervical cancer progression and may provide potential targets for cervical cancer therapy

    Full Text Available Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so-called carcinosarcoma. Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that presented as a cervical mass. We describe a 55-year-old patient who had a cervical mass arising from the uterus. We performed total abdominal hysterectomy and bilateral salpingo-oophorectomy and surgical staging (including (peritoneal washings, suspicious areas or peritoneal surfaces sampled, infracolic omental sampling, pelvic and paraaortic lymph node sampling, and appendectomy. Carcinosarcomas of the uterine cervix are extremely rare, and when a post-menopausal woman with a cervical mass is admitted to the gynecology clinic, the physician should keep in mind that the mass might be a carcinosarcoma.

    Full Text Available High-grade neuroendocrine carcinoma of the urinary bladder comprehends small-cell and large-cell variants. It is a rare and aggressive neoplasm, mostly diagnosed in advanced stages. It is more frequently encountered among Caucasian men in the sixth decade of life. Urinary symptoms are the most common clinical presentation. Diagnosis is generally not troublesome once the lesions are easily detectable by imaging exams and cystoscopy. This neoplasia is associated with tobacco smoking, and is frequently associated with other carcinomatous components such as urothelial carcinoma, adenocarcinoma, and sarcomatoid carcinoma. The authors report a case of an apparently healthy female patient who presented cervical lymph node enlargement not accompanied by systemic symptoms. The supraclavicular lymph node biopsy revealed metastatic small cell carcinoma. The computed tomography scan showed a bladder wall nodular thickening, enlarged lymph nodes along the iliac, periaortic, mediastinal, cervical and supraclavicular chains, as well as an insufflating lytic bone lesion in the right iliac wing. The positron emission tomography-fluorodeoxyglucose (PET-FDG added to these findings, the presence of a paraesophageal lymph node, lymphadenomegaly in the gluteal region and a vertebral lytic lesion in T10. Resected specimen of the bladder tumor revealed a high-grade neuroendocrine carcinoma with small-cell and large-cell features.

    Full Text Available Due to the highly glycolytic metabolism of solid tumours, there is an increased acid production, however, cells are able to maintain physiological pH through plasma membrane efflux of the accumulating protons. Acid efflux through MCTs (monocarboxylate transporters constitutes one of the most important mechanisms involved in tumour intracellular pH maintenance. Still, the molecular mechanisms underlying the regulation of these proteins are not fully understood. We aimed to evaluate the association between CD147 (MCT1 and MCT4 chaperone and MCT expression in cervical cancer lesions and the clinico-pathological significance of CD147 expression, alone and in combination with MCTs. The series included 83 biopsy samples of precursor lesions and surgical specimens of 126 invasive carcinomas. Analysis of CD147 expression was performed by immunohistochemistry. CD147 expression was higher in squamous and adenocarcinoma tissues than in the non-neoplastic counterparts and, importantly, both MCT1 and MCT4 were more frequently expressed in CD147 positive cases. Additionally, co-expression of CD147 with MCT1 was associated with lymph-node and/or distant metastases in adenocarcinomas. Our results show a close association between CD147 and MCT1 and MCT4 expressions in human cervical cancer and provided evidence for a prognostic value of CD147 and MCT1 co-expression.

    Twenty-four patients with carcinoma of the cervix were examined preoperatively by MR imaging and CT. In all patients histopathologic confirmation was available for specimens obtained either by radical hysterectomy or at staging laparotomy. MR imaging was equivalent to contrast CT in the detection and evaluation of tumor extension in the cervix. Tumor extension to the parametria and pelvic wall was difficult to evaluate on both modalities, as neither had a higher accuracy than pelvic examination conducted under anesthesia. Nodal staging was nearly equivalent on MR imaging and CT. In the detection and staging of carcinoma of the cervix, MR imaged proved to be as good as CT with contrast agent enhancement

    The cervical cancer is the third most common malignancy in women in the world. Despite advances in screening and treatment there are a relatively large number of patients who are diagnosed with advanced stage of disease, or who have inoperable recurrence. In this group of patients, the main aim of a treatment is palliative intent. The main cytotoxic agent is cisplatin, but the responses are also observed with other chemotherapy agents. Improved therapeutic results are observed with combined platinum-based chemotherapy regimens as compared to cisplatin monotherapy. Overall, however, the treatment results in advanced, persistent and recurrent cervical cancer are unfavorable and disease is considered to be relatively chemo resistant. The new treatment approaches are searched and a significant therapeutic benefit, as far as progression-free and overall survival, has been recently demonstrated when adding bevacizumab to systemic chemotherapy. The current article is a review of systemic treatment in advanced, persistent and recurrent metastatic carcinoma of the cervix. (author)

    Nasopharyngeal carcinoma (NPC) is a common cancer in Malaysia. The clinical presentation in Sarawak has not been well documented. A retrospective review of 213 selected NPC cases was undertaken on the clinical records in Sarawak General Hospital, Sarawak, from June 1999 to June 2003. There were 116 patients in Kuching and 97 in Serian. There were twice as many males as females. The youngest patient was 16 and the oldest 88 years old with a mean age of 51 years. The four most common symptoms in order of frequencies were cervical lymphadenopathy, epistaxis, hearing loss and diplopia. 80.8% of the patients presented with cervical lymphadenopathy and about 85% of the patients presented in the advanced stages. Very small percentages of the patients were found to have single presenting symptoms of epistaxis (2.4%) and hearing loss (0.5%).

    To evaluate the association of sociodemographic and hospital characteristics with adherence to National Comprehensive Cancer Network treatment guidelines for stage IB-IIA cervical cancer and to analyze the relationship between adherent care and survival. This is a retrospective population-based cohort study of patients with stage IB-IIA invasive cervical cancer reported to the California Cancer Registry from January 1, 1995, through December 31, 2009. Adherence to National Comprehensive Cancer Network guideline care was defined by year- and stage-appropriate surgical procedures, radiation, and chemotherapy. Multivariate logistic regression, Kaplan-Meier estimate, and Cox proportional hazard models were used to examine associations between patient, tumor, and treatment characteristics and National Comprehensive Cancer Network guideline adherence and cervical cancer-specific 5-year survival. A total of 6,063 patients were identified. Forty-seven percent received National Comprehensive Cancer Network guideline-adherent care, and 18.8% were treated in high-volume centers (20 or more patients/year). On multivariate analysis, lowest socioeconomic status (adjusted odds ratio [OR] 0.69, 95% CI 0.57-0.84), low-middle socioeconomic status (adjusted OR 0.76, 95% CI 0.64-0.92), and Charlson-Deyo comorbidity score 1 or higher (adjusted OR 0.78, 95% CI 0.69-0.89) were patient characteristics associated with receipt of nonguideline care. Receiving adherent care was less common in low-volume centers (45.9%) than in high-volume centers (50.9%) (effect size 0.90, 95% CI 0.84-0.96). Death from cervical cancer was more common in the nonadherent group (13.3%) than in the adherent group (8.6%) (effect size 1.55, 95% CI 1.34-1.80). Black race (adjusted hazard ratio 1.56, 95% CI 1.08-2.27), Medicaid payer status (adjusted hazard ratio 1.47, 95% CI 1.15-1.87), and Charlson-Deyo comorbidity score 1 or higher (adjusted hazard ratio 2.07, 95% CI 1.68-2.56) were all associated with increased

    High-risk human papillomavirus (HPV) type 16, which is responsible for greater than 50% of cervical cancer cases, is the most prevalent and lethal HPV type. However, the molecular mechanisms of cervical carcinogenesis remain elusive, particularly the early steps of HPV infection that may transform normal cervical epithelium into a pre-neoplastic state. Here, we report that a group of microRNAs (microRNAs) were aberrantly decreased in HPV16-positive normal cervical tissues, and these groups of microRNAs are further reduced in cervical carcinoma. Among these miRNAs, miR196a expression is the most reduced in HPV16-infected tissues. Interestingly, miR196a expression is low in HPV16-positive cervical cancer cell lines but high in HPV16-negative cervical cancer cell lines. Furthermore, we found that only HPV16 early gene E5 specifically down-regulated miRNA196a in the cervical cancer cell lines. In addition, HoxB8, a known miR196a target gene, is up-regulated in the HPV16 cervical carcinoma cell line but not in HPV18 cervical cancer cell lines. Various doses of miR196a affected cervical cancer cell proliferation and apoptosis. Altogether, these results suggested that HPV16 E5 specifically down-regulates miR196a upon infection of the human cervix and initiates the transformation of normal cervix cells to cervical carcinoma.

    We evaluated the expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase-2 (MMP-2) in nasopharyngeal carcinoma (NPC) and studied their relationship with cervical lymph node metastasis. Immunohistochemical staining was used to detect the expression of EMMPRIN and MMP-2 in specimens from patients with chronic nasopharyngitis (CN), nonmetastastic NPC (NM-NPC), and lymph node-metastatic NPC (LNM-NPC). The rates of positive EMMPRIN expression in CN, NM-NPC, and LNM-NPC were 13.3%, 30.0%, and 66.7%, respectively. Significant differences were found between the rates in CN and LNM-NPC (p correlated (rs = 0.466; p <0.01). Nasopharyngeal carcinoma cells may attain enhanced metastastic capability through the expression of MMP-2 induced by EMMPRIN.

    The aim of the study was to characterize CT images and stages of carcinomas localized in the antral part of the stomach obtained with spiral CT. Seven men aged from 54 years old to 81 years old inclusive, with subjective complaints and clinical suspicion of a neoplasm in the upper gastrointestinal tract were examine Examinations were performed following stomach wall re relaxation with Buscolysin.The stomach is distended by drinking 600 ml of water. Upper abdomen scans were performed with spiral CT/e General Electric with the following parameters: slice thickness 3-5 mm, spacing 3 mm, pitch 1,5, reconstruction index 3 mm. After the pre-contrast scans, 100 ml of non-ionic contrast media is administered intravenously with an injection rate of 30 ml/sec. Scan delay time - 30 seconds after start of injection. Exposition data-120 kV, 180 mAs. Carcinoma localized in the antral part of the stomach was demonstrated in 7 patients. The staging showed: I stage - one patient, II stage - 2, III stage - 1 and IV stage - three patients. According to the macro morphological characteristic: exophytic type - 4, endophytic tumor - 1, ulcerous tumor - 1 and early carcinoma - 1 patient. In our material only male patients were present. Early carcinoma was demonstrated in a male patient at an age of 80 years old. An enhancing nodular local thickness was visualized. Differential diagnosis between malignant and benign ulcer is necessary in certain cases. It is performed on the contrast scans, the malignant process enhances twice its density, When performing a purposive CT examination it is possible to diagnose neoplasms in the antral part of the stomach, from stage i to IV with different macro morphologic characteristic

    Since the introduction of screening programs for cervical cancer (CC) the incidence has decreased and CC is discovered at an earlier stage. The purpose of this study was to analyze time trends in age, stage, and histopathology over a 90-year period and to our knowledge this is the largest single institutional series in the literature of invasive cervical carcinoma (CC) cases. This is a retrospective study comprising 18,472 women treated for CC from 1914 until 2004 at Radiumhemmet, Stockholm. The material is part of the international CC statistics published since 1937 in the League of Nations' Annual Reports, and since 1958 under the patronage of International Federation of Gynecology and Obstetrics (FIGO). During the 90-year study period, the annual number of cases treated increased to over 400 up until 1965, after which there was a gradual drop to less than 100 cases in 2004. A pronounced shift toward earlier stages at diagnosis was noted. The mean age at diagnosis increased in all stages, predominantly in advanced stages. A reduction in squamous cell carcinoma (SCC) cases and a sixfold increase in the proportion of adenocarcinoma (AC) cases were observed. The mean age at diagnosis for squamous and AC cases shifted after 1970, when the SCC cases ultimately became 3 years older than the AC cases in contrast to around 1950 when they were 3 years younger than the AC cases. The changes in the distribution by age, stage, and histopathology during this 90-year period are probably associated with: improved social conditions and increased access to health care, the introduction of screening programs for CC in the 1960s, and a change in the risk factors for CC (changed sexual behavior, introduction of contraceptive pills, and changed smoking habits). This is a study on changes in the distribution by age, stage, and histopathology in a large series of cervical cancer treated in Sweden during a 90-year period. It also includes an historical review about the development

    Clinical and pathological indicators are inadequate for prognosis of stage II and III colorectal carcinoma (CRC). In this study, we utilized the activity of regulatory factors, univariate Cox regression and random forest for variable selection and developed a multivariate Cox model to predict the overall survival of Stage II/III colorectal carcinoma in GSE39582 datasets (469 samples). Patients in low-risk group showed a significant longer overall survival and recurrence-free survival time than those in high-risk group. This finding was further validated in five other independent datasets (GSE14333, GSE17536, GSE17537, GSE33113, and GSE37892). Besides, associations between clinicopathological information and risk score were analyzed. A nomogram including risk score was plotted to facilitate the utilization of risk score. The risk score model is also demonstrated to be effective on predicting both overall and recurrence-free survival of chemotherapy received patients. After performing Gene Set Enrichment Analysis (GSEA) between high and low risk groups, we found that several cell-cell interaction KEGG pathways were identified. Funnel plot results showed that there was no publication bias in these datasets. In summary, by utilizing the regulatory activity in stage II and III colorectal carcinoma, the risk score successfully predicts the survival of 1021 stage II/III CRC patients in six independent datasets.

    Background and purpose: The CD24 marker is expressed in various carcinomas and is associated with shorter survival rates. We evaluated the prognostic significance of CD24 protein overexpression in patients treated with post-operative radiotherapy (RT) after surgery, and its prognostic significance and specific role stratified by adjuvant treatment modalities. Materials and methods: We determined the CD24 expression status of 140 patients with cervical squamous cell carcinoma treated with RT alone or with chemoradiotherapy (CRT) after radical hysterectomy procedures. Results: CD24 expression was detected in 59 patients (42%) and was significantly associated with locoregional failure-free survival (LRFFS) (p = 0.0218), distant metastasis-free survival (DMFS) (p = 0.0001), and overall survival (OS) (p = 0.0053). In the multivariate analysis, CD24 positivity was also significantly associated with DMFS (p = 0.025) and OS (p = 0.045). CD24 expression stratified by post-operative treatments (CRT or RT alone) was associated with DMFS (p = 0.0001) but not with LRFFS (p = 0.4423) in the CRT group. However, CD24 expression was associated with LRFFS (p = 0.0198) but not with DMFS (p = 0.5269) in the RT alone group. Conclusions: CD24 expression is an independent prognostic marker in patients with cervical squamous cell carcinoma, even adjuvant treatment after surgery. And this study reveals different prognostic role of CD24 expression in two subgroups treated differently after surgery. Therefore, new therapeutic strategies targeting CD24 expression stratified by subgroups might have important clinical implications.

    Purpose: The goal of this exemplary study was to integrate morphological and functional MRI to establish computer-based, preoperative therapy planning for tumors, instancing cervical carcinoma. Results: Segmentation of organs and vessels as well as tissue differentiation yielded a morphological visualisation of anatomical structures that were overlaid with pharmacokinetic parameters derived from dynamic MRI, subsequently. Thereby, three-dimensional, arbitrary views on the functional data were displayed. Conclusions: Image analysis and visualisation of the acquired MR data establishes both a morphologic and functional evaluation of suspect lesions and adjacent organs. By integrating morphologic and functional MRI additional information can be gathered that possibly impinge on preoperative planning. (orig./AJ) [de

    Tobacco smoking is considered a risk factor for cervical cancer development due to the presence of tobacco based carcinogenic metabolites in cervical cells of female smokers. In this study, we investigated the role of the T3801C (MspI) polymorphism of CYP1A1, a gene encoding an enzyme necessary for the initiation of tobacco based carcinogen metabolism, on cervical cancer risk. The T to C substitution may alter CYP1A1 activities, potentially elevating cervical cancer risk. Since results of gene-disease association studies vary according to the study population, the multi-ethnic population of Malaysia provides an excellent representative cohort for identifying and comparing the cervical cancer risk among the 3 major ethnics in Southeast Asia in relation to CYP1A1 MspI polymorphism. A total of 195 Thin Prep Pap smear samples from HPV negative and cancer free females were randomly selected as controls while 106 formalin fixed paraffin embedded samples from females with invasive cervical cancer were randomly selected for the cases group. The polymorphisms were identified using restriction fragment length polymorphism (RFLP) PCR. We found no significant associations between CYP1A1 MspI polymorphism and cervical cancer in the general Malaysian female population. However, upon ethnic stratification, the variant C/C genotype was significantly associated with a 4.66-fold increase in cervical cancer risk in Malay females (95% CI= 1.21-17.9; p=0.03). No significant association was observed in the Chinese and Indian females. Additionally, there were no significant associations in the dominant model and allele frequency model analysis in both the general and ethnically stratified female population of Malaysia. Our findings suggest that the C/C genotype of CYP1A1 MspI polymorphism is associated with the development of cervical carcinoma in the Malay females of Malaysia.

    Patients with human immunodeficiency virus (HIV) infection have a statistically significant increased risk of developing cervical cancer. The expression of the human Ki-67 protein is strictly associated with cell proliferation. The purpose of our work was detection of proliferative activity in cervical squamous cancer in women with HIV infection. We investigated 24 cases (12 patients with HIV and 12 patients without HIV infection) of cervical carcinoma, where biopsy had been performed before the treatment. According to histopathological diagnoses, well-differentiated, moderately and poorly differentiated squamous cell carcinoma (7, 13 and 4 cases respectively) was determined. Mean age of women in the group with HIV infection was 32.7 years, and 38.2 years in the group without HIV infection. Detection of protein Ki-67 expression was performed with nuclear staining in the intermediate and superficial cells. The results of this work show that proliferative activity of cervical squamous cancer in women with HIV infection is characterized by a higher level of Ki-67 with averaging level for all histological types of squamous cell carcinoma 62.5±5.6% that is one and half times higher than in group without HIV infection. Depending on a histological type, expression of Ki-67 has increased from 4.7±3.8% in well-differentiated squamous cell carcinoma up to 89.2±5.1% in poorly differentiated squamous cell carcinoma for group with HIV, and from 21.3±2.4% to 79.4±3.7 in group without HIV.

    Thymidine kinase 1 (TK1) is a proliferation biomarker that has been found useful for prognostication in cancer patients. Here we investigate for the first time the use of TK1 expression as a prognostic factor for patients with premalignant and malignant lesions of the uterine cervix. TK1 expression was determined by immunohistochemistry in cervical lesions (cervical intraepithelial neoplasia (CIN), n = 216; invasive cervical carcinoma, n = 84). TK1 and Ki-67 expressions and pathological/FIGO stages and age were correlated with 5-year survival by Kaplan-Meier, log rank and COX hazard uni- and multivariate analyses. TK1 labeling index (LI) was significantly correlated with CIN grades and invasive cervical carcinoma stages, while TK1 labeling intensity was only correlated to CIN grades. TK1 LI was significantly higher compared with Ki-67 LI. TK1 LI correlated significantly to 5-year survival in patients with invasive cervical carcinoma, particularly nuclear TK1 LI. In a multivariate analysis, nuclear TK1 expression was independent prognostic factor in patients with in situ/invasive cervical carcinoma or in invasive cervical carcinoma alone. Interestingly, in invasive cervical carcinoma patients with advanced tumors, nuclear TK1 expression could identify patients with significantly better survival rates (80%), while Ki-67 could not. Nuclear TK1 expression in early grade CIN predicts risk for progression to malignancy. Nuclear TK1 expression is also a prognostic factor for treatment outcome, particularly in patients with advanced cervical carcinomas. Nuclear TK1 expression is more useful than Ki-67 and pathological/FIGO stages

    This study was done to evaluate the clinical feasibility of FDG-PET scan in patients with cervical carcinoma. PET-scans were performed in 74 patients with cervical carcinoma from March, 1998 to September, 1998. Fourteen cases were done at pretreatment period and sixty cases were done at post-treatment follow up period. In this study, the scans were obtained after bladder emptying by foley catheter insertion and diuretics to reduce the tracer activity in the bladder and improve the images of central lesions. We could find some incidental recurrent or metastatic lesions by FDG-PET scan (at pretreatment; 5 cases, at post-treatment; clinically no evidence of disease; 8 cases). FDG-PET scan had high sensitivity (100%) for central lesions and metastatic lymph nodes of cervical cancer but could not precisely define the anatomic location of the cancer and the sensitivity was not superior than MRI. Earlier detection of metastatic lymph nodes was superior than CT/MRI (sensitivity; 100 %) for metastatic lymph nodes. Also we found 3 double primary cancers incidentally (2 lung cancers and 1 thyroid cancer). In conclusion, FDG-FET scan might be useful for the earlier of hidden lesions that cannot be detected by routine conventional methods and differential diagnosis with radiation fibrosis and benign lymph adenophy.

    Full Text Available Background: Cervical carcinoma is a common cause of death in India. It is presented by spectrum of precancerous lesions, called cervical intraepithelial neoplasia (CIN. Cervical cytological screening is designed to detect over 90% of cytological abnormalities. It has been established that cervical cancers can be diagnosed at the pre-invasive stage with adequate, repetitive cytological screening. Keeping in view of the importance of cervical PAP abnormalities & by classifying them by Bethesda terminology; correlation with clinical findings & histopathological findings was done. Methods: All cervical Pap smears reported in Department of Pathology from 1st August 2015 to 31st July 2016, were prospectively studied and classified according to revised Bethesda terminology, 2014. Also cytoradiological and clinico-cytological, cytohistological correlation was studied. Results: Due to increasing awareness among masses inculcated by social workers, most of the patients for PAP smear cytology came for routine screening to rule out cervical lesions followed by clinical finding of per-vaginal discharge. The 350 screened patients were in the third and fourth decades of life. 99/350 cases were subjected to USG study, with maximum number of cases (34 cases showing normal study, followed by cases with ovarian cysts and fatty liver disease. Negative for intra-epithelial lesion (NILM without any denotable organism was the pre-dominant cytological finding of PAP smear study followed by cases of NILM with bacterial vaginosis (30 cases with two malignancies. Intra-epithelial lesions (IELs were noted in 16.86%. ASCUS comprised 12.29%, ASC-H comprised 1.14%, L-SIL comprised 1.71%, HSIL comprised 1.43%, Atrophic cervical smears comprised 5.14%, Squamous cell carcinoma comprised 0.29% cases. ASC/LSIL ratio was 7.8 and inadequacy rate for PAP smear study was 7.43%. Cytologyhistopathology correlation was possible in 62 cases. Conclusion: Classification of cervical PAP

    We evaluated the feasibility of performing CT volumetry of gastric carcinoma (GC) and its correlation with TNM stage. This institutional review board-approved retrospective study was performed on 153 patients who underwent a staging CT study for histologically confirmed GC. CT volumetry was performed by drawing regions of interest including abnormal thickening of the stomach wall. Reproducibility of tumour volume (Tvol) between two readers was assessed. Correlation between Tvol and TNM/peritoneal staging derived from histology/surgical findings was evaluated using ROC analysis and compared with CT evaluation of TNM/peritoneal staging. Tvol was successfully performed in all patients. Reproducibility among readers was excellent (r = 0.97; P = 0.0001). The median Tvol of GC showed an incremental trend with T-stage (T1 = 27 ml; T2 = 32 ml; T3 = 53 ml and T4 = 121 ml, P < 0.01). Tvol predicted with good accuracy T-stage (≥T2:0.95; ≥T3:0.89 and T4:0.83, P = 0.0001), M-stage (0.87, P = 0.0001), peritoneal metastases (0.87, P = 0.0001) and final stage (≥stage 2:0.89; ≥stage 3:0.86 and stage 4:0.87, P = 0.0001), with moderate accuracy for N-stage (≥N1:0.75; ≥N2:0.74 and N3:0.75, P = 0.0001). Tvol was significantly (P < 0.05) more accurate than standard CT staging for prediction of T-stage, N3-stage, M-stage and peritoneal metastases. CT volumetry may provide useful adjunct information for preoperative staging of GC. (orig.)

    Introduction Anastomotic leak is one of the main causes of morbidity following esophageal resection for carcinoma of the esophagus and gastroesophageal junction. We compared hand sewn and stapled cervical esophagogastric anastomotic techniques in terms of postoperative complications. Methods All patients who underwent esophagectomy with cervical esophagogastric anastomosis at a single academic center from 2004 to 2014 were included in the study. Both early and late complications were analyzed. Results 153 patients underwent resection for carcinoma of the esophagus and gastroesophageal junction. Of these 140 patients had esophagectomy with cervical esophagogastric anastomosis. 66 patients underwent a hand sewn anastomosis and 74 patients had a side-to-side stapled anastomosis fashioned. Both groups were comparable with respect to preoperative characteristics. There was no difference in the operative blood loss and T and N stage of the disease. The overall morbidity and mortality was 32.8% and 6.4%, respectively. Overall leak rate was 17%. There was no difference in the leak rates among two groups (12 in the hand-sewn group & 12 in the Stapled stapled group; p = 0.82). The rate of anastomotic stricture was significantly higher for the hand sewn group (16.1% vs 4.3%; p = 0.03) at median follow up of 30 months. Conclusion Both hand sewn and stapled anastomotic techniques are equally effective way of performing a cervical esophagogastric anastomosis. However, patients having anastomotic leak develop anastomotic stricture more often in those having hand-sewn anastomosis compared to stapled anastomosis. PMID:27222711

    The relationship between the apoptosis and the expression of proliferating cell nuclear antigen (PCNA) and the clinical stages in gastric cancers was studied. By using terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) technique and PCNA immunohistochemical staining, the apoptosis and the expression of PCNA in tissue of gastric carcinoma were assayed in situ, the index of apoptosis (AI), index of PCNA (PI) and the rate of AI/PI were calculated. AI and PI in gastric cancer tissues were (6.5 +/- 3.7)% and (49.8 +/- 15.9)% respectively, and the rate of AI/PI was 0.13 +/- 0.05, which were obviously different from those of normal gastric mucosa in paragastric cancer (P stages of gastric carcinoma, the AI was decreased, PI was increased and the rate of AI/PI decreased in gastric carcinoma. There was significant difference in them between the gastric cancer tissues and normal gastric mucosa in pericarcinoma in TNM stage II to IV (P gastric carcinoma. The AI, PI and the rate of AI/PI would become the prognostic factors in advanced gastric carcinoma.

    To investigate prognostic significance of clinical and pathological stages in patients with locally advanced rectal carcinoma treated with neoadjuvant chemoradiotherapy (neo-CRT) and total mesorectal excision. 210 patients with locally advanced rectal carcinoma (cT3-4 or cN+) treated with neo-CRT followed by total mesorectal excision. Treatment outcomes were compared according to clinical and pathological stage. Overall survival (OS), disease free survival (DFS) among patients with different clinical stage and pathological stage after neo-CRT. The median follow-up time was 47 months (range, 14–98 months). Clinical T stage was associated with 5 year OS (p = 0.042) and 5 year DFS (p = 0.014) while clinical N stage was not associated with 5 year OS (p = 0.440), 5 year DFS (p = 0.711). Pathological T stage was associate with 5 year OS (p = 0.001) and 5 year DFS (p = 0.046); and N stage was associated with 5 year OS (p = 0.001), 5 year DFS (p = 0.002). The pathological stage was further classified into three groups: ypT0–2N0 in 91 patients (43.3 %), ypT3–4N0 in 69 patients (32.9 %) and ypT0–4N+ in 50 patients (23.8 %). While pathological stage (ypT0–2 vs ypT3–4N0 vs ypT0–4N+) was associated with 5 year OS (87.9 %, 75.5 %, 56.7 %, p = 0.000), 5 year DFS (74.5 %, 77.4 %, 50.5 %, p = 0.003). Multivariate analysis showed that ypN stage was an independent prognostic factor for patients 5 year DFS. Pathological stage is strongly associated with treatment outcomes in patients with locally advanced rectal carcinoma treated with neo-CRT followed by total mesorectal excision, which may be used as guidance for further individualized treatment

    Full Text Available Abstract Background The occurrence of skeletal muscle metastases is a very rare event. Only two cases of late skeletal muscle recurrence from cervical cancer have been documented until now. Case presentation A 38-year old patient, submitted to radical hysterectomy and pelvic lymphadenectomy for a squamous FIGO stage IB1 cervical carcinoma, presented after 76 months with a palpable, and painless swelling on the left hemithorax. MRI showed a nodule located in the context of the intercostal muscles. Pathology revealed the presence of metastasis of squamous cell carcinoma of similar morphology as the primary. On the basis of FDG-PET findings, which excluded other sites of disease, surgical excision of the lesion was performed. The patient was triaged to chemotherapy plus external radiotherapy. Conclusion A case of skeletal muscle recurrence from cervical cancer after a very long interval from primary diagnosis is reported. Muscular pain or weakness, or just a palpable mass in a patient with a history of cancer has always to raise the suspicion of muscle metastasis.

    Full Text Available Small cell carcinoma of the gastrointestinal tract is a rare and aggressive neuroendocrine tumor. This study aims to analyze the clinical characteristics and potential prognostic factors for patients with limited stage small cell carcinoma of the gastrointestinal tract. The records of 27 patients with limited stage small cell carcinoma of the gastrointestinal tract, who all received surgery with lymphadenectomy, were retrieved and analyzed retrospectively. The median age of patients was 60 years old (range 38-79. The primary locations of tumor were the esophagus (74.1% and stomach (14.8%. The rate of preoperative accurate diagnosis (16.7% was low for small cell carcinoma of the esophagus and stomach. 40.7% of all the patients had regional lymph node metastases. Five patients underwent surgery alone, and the other 22 were treated with surgery + postoperative chemotherapy. All patients had disease progression or recurrence. The overall median survival time was 10 months and the 1-year survival rate was 37.0%. Patients who received postoperative chemotherapy had a median survival time of 12 months, which was superior to the 5-month survival of for those who only had surgery (P<0.0001. TNM stage (P=0.02 and postoperative chemotherapy (P<0.0001 were considered as two prognostic factors in univariate analysis. Postoperative chemotherapy was a significant independent prognostic factor in multivariate analysis (P=0.01. The prognosis for patients with limited stage small cell carcinoma of the gastrointestinal tract remains dismal, however, postoperative chemotherapy may have the potential to improve the outcome for these patients.

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    We wanted to determine the clinical characteristics and prognosis according to the VEGF expression in stage II cervical carcinoma patients treated with definitive radiotherapy. We enrolled 31 patients who were diagnosed with cervical cancer from 1995 to 2003 at Samsumg Medical Center and their paraffin block tissue samples were available for study. The median age of the patients was 65 years. The mean tumor size was 4.1 cm (range: 1.2 ∼8.2 cm). Seven patients (22.6%) were suspected of having pelvic lymph node metastasis. An external beam irradiation dose of 45-56.4 Gy was administered to the whole pelvis with a 15 MV linear accelerator, and an additional 24 Gy was given to point A by HDR intracavitary brachytherapy. VEGF staining was defined as positive when more than 10% of the tumor cells were stained. The median follow-up duration was 58 months. A positive VEGF expression was observed in 21 patients (67.7%). There was no significant correlation between the VEGF expression and pelvic lymph node metastasis, tumor size and the response of radiotherapy. During follow-up, 7 patients had recurrence. The complete response rate was not significant between the VEGF (-) and VEGF(+) tumors. However, the VEGF(+) tumors showed a significantly higher recurrence rate in comparison with the VEGF(-) tumors (ρ = 0.040). The three year disease-free survival rates were 100% and 66.7%, respectively, for patients with VEGF(-) or VEGF(+) tumor (ρ = 0.047). The VEGF expression was a significant factor for recurrence and disease-free survival. However, the significance of the VEGF expression is still controversial because of the various definitions of VEGF expression and the mismatches of the clinical data in the previous studies

    During a period of 17 years, between 1961 and 1977, 59 cases of the cervical stump cancer were treated at NIRS Hospital. We could not epidemically find the difference between the cervical stump cancer and the cervical cancer. 5-year survival rate of cervical stump cancer was 90% in stage I, 86% in stage II, and 63% in stage III, respectively. These results show higher 5-year survival rates, compared with those of cervical cancer. The frequencies of radiation complication in rectum and bladder were lower in the case of cervical stump cancer than in cervical cancer. It was suggested that the optimal radiation dose for cervical stump cancer was 80 - 90 TDF at point A. (author)

    Cervical cancer is an important cause of mortality among women in developing countries, especially in the Latin America and Caribbean (LAC) region. Infection with high-risk (HR) human papillomavirus (HPV) has been identified as the primary cause of cervical cancer. The aim of this study was to determine the frequency of HR-HPV genotypes in low-grade and high-grade squamous intraepithelial lesions (LSIL, HSIL) and cervical carcinoma (CC) among Venezuelan women. Subjects with histopathological diagnosis of LSIL, HSIL, and CC (LSIL=200; HSIL=100; CC=150) were enrolled in the study after obtaining informed consent. Biopsy samples of these subjects were analyzed to determine the lesion type. HPV detection and typing was done using polymerase chain reaction (PCR) and reverse hybridization. HPV type specific prevalence was determined in subjects with single and multiple infections. HPV DNA was detected in 68%, 95%, and 98.7% of LSIL, HSIL, and CC cases, respectively. HR-HPV and low-risk oncogenic HPV (LR-HPV) was observed in 66.9%/11.8% of LSIL cases, 87.3%/3.2% of HSIL cases, and 91.2%/0.7% of CC cases. HPV types -16/-18 (65%) were the most common high-risk HPV types observed, followed by types -52, -33, -45, and -31. Cervical cancer burden in Venezuelan women is substantial. HPV types -16/-18 were the most common types prevalent among Venezuelan women followed by types -52, -33, -45, and -31 (prevalence, ~90.1%). The results of this study provide baseline information on the HPV type distribution, which may facilitate the development of a cervical cancer prevention and control program in Venezuela.

    Serous carcinoma of the uterine cervix (USCC) is an extremely rare subtype. To establish the treatment strategy in patients with USCC is an important issue. MEDLINE (PubMed) was searched for all articles published after the first publication by Lurie et al. [Eur J Obstet Gynecol Reprod Biol 1991; 40: 79-81], reporting woman diagnosed with USCC. Because of limited numbers of studies on the topic of the study, we could not keep a restriction of eliminating smaller sample sizes. A search of PubMed demonstrated that 113 cases of USCC have been reported in the literature since the first publication. The current treatment modality adopted for early cervical cancer is hysterectomy with bilateral iliac-obturator lymphadenectomy and postoperative radiotherapy (RT) or radiochemotherapy (RT-CT) if risk factors for cervical carcinoma appear. The treatment strategy for locally advanced USCC is preoperative RT-CT or chemotherapy (CHTH) with the intention to treat the patient surgically. The treatment option for disseminated disease is CHTH with paclitaxel and carboplatin. Risk factors and a more advanced clinical stage of USCC have an impact on poor outcomes despite the use of standard treatment methods, adapted for cervical cancer. The outside-pelvic failures tend to seek effective systemic treatment. © 2018 S. Karger AG, Basel.

    Carcinoma of uterine cervix is the second most common cancers among women worldwide. Combined radiation and chemotherapy is the choice of treatment for advanced stages of the disease. The prognosis is poor, with a five-year survival rate ranging from about 20–65%, depending on stage of the disease. Therefore, genetic characterization is essential for understanding the biology and clinical heterogeneity in cervical cancer (CC). We used a genome-wide screening method – comparative genomic hybridization (CGH) to identify DNA copy number changes in 77 patients with cervical cancer. We applied categorical and survival analyses to analyze whether chromosomal changes were related to clinico-pathologic characteristics and patients survival. The CGH analysis revealed a loss of 2q33-q37 (57.1%), gain of 3q (54.5%) and chromosomal amplifications (20.77%) as frequent genetic changes. A total of 15 amplified chromosomal sites were detected in 16 cases that include 1p31, 2q32, 7q22, 8q21.2-q24, 9p22, 10q21, 10q24, 11q13, 11q21, 12q15, 14q12, 17p11.2, 17q22, 18p11.2, and 19q13.1. Recurrent amplified sites were noted at 11q13, 11q21, and 19q13.1. The genomic alterations were further evaluated for prognostic significance in CC patients, and we did not find any correlation with a number of clinical or histological parameters. The tumors harboring HPV18 exhibited higher genomic instability compared to tumors with HPV 16. This study demonstrated that 2q33-q37 deletions, 3q gains and chromosomal amplifications as characteristic changes in invasive CC. These genetic alterations will aid in the identification of novel tumor suppressor gene(s) at 2q33-q37 and oncogenes at amplified chromosomal sites. Molecular characterization of these chromosomal changes utilizing the current genomic technologies will provide new insights into the biology and clinical behavior of CC

    To investigate the clinical usefulness of a follow-up examination using serum squamous cell carcinoma antigen (SCC) for the early detection of recurrence in patients treated for cervical squamous cell carcinoma. 20 patients who were treated for recurrent cervical squamous cell carcinoma between 1997 and 1998, who had experienced a complete remission after radiotherapy and who underwent an SCC test around the time when recurrence was detected, were included in this study. The levels of SCC were measured from the serum of the patients by immunoassay and values less than 2 ng/mL were regarded as normal. The sensitivity of the SCC test for use in the detection of recurrence, the association between the SCC values and the recurrence patterns and the tumor size and stage, and the temporal relation between the SCC increment and recurrence detection were evaluated. The SCC values were above normal in 17 out of 20 patients, so the sensitivity of the SCC test for the detection of recurrence was 85%, and the mean and median of the SCC values were 15.2 and 9.5 ng/mL, respectively. No differences were observed in the SCC values according to the recurrence sites. For 11 patients, the SCC values were measured over a pero id of 6 months before recurrence was detected, and the mean and median values were 13.6 and 3.6 ng/mL, respectively. The SCC values of 7 patients were higher than the normal range, and the SCC values of the other 4 patients were normal but 3 among them were above 1.5 ng/mL. At the time of diagnosis, the SCC valuess were measured for 16 of the 20 recurrent patients, and the SCC values of the patients with a bulky tumor (≥ 4 cm) or who were in stage IIb or III were higher than those of the patients with a non-bulky tumor or who were in stage Ib or IIa. The SCC test is thought to be useful for the early detection of recurrence during the follow up period in patients treated for cervical squamous cell carcinoma.

    Objective: To compare local control and toxicity in patients treated with external beam radiotherapy followed by intracavitary brachytherapy (BT) versus external beam radiotherapy alone (RT) for locally early stage nasopharyngeal carcinoma (NPC). Methods: From 1990 to 1997, 126 NPC patients staged T1 and T2 by 1992 Fuzhou Staging System (oropharynx, carotid sheath and soft tissue around cervical vertebral involvement excluded) were randomized into RT alone and RT followed BT groups. The two groups were comparable in age, gender, stage and pathology. The median follow-up was 112 months. T1 patients were randomized before the treatment into RT alone group of 66-70 Gy and RT plus BT with the dose of 56 Gy plus 10-16 Gy BT boost to the nasopharynx. For T2 patients, if MRI or CT showed no residual lesion in parapharyngeal space after 50 Gy, they were randomized into RT alone (median dose: 72 Gy) or RT of 66 Gy followed by 8-24 Gy BT boost (1-3 fractions over 1-3 weeks). Results: In RT group, 8 patients (13.1%) failed in primary site during the follow-up period, 7 (11%) in BT group. The 5-year local control rates was 86% for RT group and 88% for BT group (P=0.47). The 5-year overall survival rates were 83% and 84% (P=0.84), respectively. Ten patients (18%) in RT group (4 of grade I, 6 of grade II) and 7 patients (11%) in BT group (4 of grade I, 3 of grade II, P=0.31) developed radiation induced encephalopathy. The incidence of trismus was much lower in BT group than in RT group (26% versus 10%, P=0.02). No soft palate perforation or sphenoid necrosis were observed. Conclusion: Compared to conventional external beam radiotherapy, planned irradiation plus intracavitary brachytherapy not only can achieve similar local control and survival rates for locally early stage nasopharyngeal carcinoma, but also decrease irradiation dose and the trismus incidence.

    Ionizing radiation causes single and double strand breaks (SSBs and DSBs). DSBs are among the most critical DNA lesions and can be repaired via either non-homologous end joining (NHEJ) in which PARP1, Ku70 and DNA-PKcs are important, or homologous recombination (HR), where BRCA2 and Rad51 are essential. Hyperthermia disturbs HR by temporary inactivation of BRCA2. Cisplatin disrupts NHEJ and PARP1-inhibitor blocks Poly-(ADP-ribose)polymerase- 1, which is important in SSB repair, NHEJ and backup-NHEJ. Our goal was to investigate the additional effectiveness of hyperthermia and PARP1-inhibition on radiation and/or cisplatin treatment. Cervical carcinoma cells (SiHa) were treated at different temperature levels levels (41.0-43.0℃, PARP1-inhibitor (100 μM; NU1025), gamma-irradiation doses (0-8 Gy) or cisplatin (1'R for 1 h). Clonogenic assays were carried out to measure survival and γH2AX staining was used to visualize DSBs. To elucidate mechanisms of action expression levels of DNA repair proteins BRCA2 and DNA-PKcs were investigated after 42.0℃ (1 h) using western blot. Combined hyperthermia and radiation resulted in an increased number of γH2AX foci as compared to radiation alone. Hyperthermia treatment in combination with cisplatin and PARP1 inhibitor and with radiation and PARP1 inhibitor significantly decreased cell survival. Western blot demonstrated a decreased expression of BRCA2 protein at 30 min after hyperthermia treatment. Adding PARP1-inhibitor significantly improves the effectiveness of combined hyperthermia radiotherapy and combined hyperthermia-cisplatin treatment on cervical carcinoma cells. Hyperthermia affects DNA-DSB repair as is indicated by increased γH2AX foci numbers and decreased BRCA2 expression. (author)

    Purpose: To investigate whether early-assessed radioresponse of tumors corresponds with late-assessed radioresponse, which is associated with local disease control in radiotherapy (RT) for cervical cancer. Methods and Materials: This prospective study included 12 patients with cervical squamous cell carcinoma treated by RT with or without concurrent cisplatin. Tumor volume was estimated by scheduled magnetic resonance imaging before (preRT), 3 to 4 weeks after (early assessment), and 6 to 7 weeks after (late assessment) RT initiation. Radioresponse was assessed with tumor shrinkage curves based on these volumes. Radioresponse for each tumor was calculated as the slope (day -1 ) of the shrinkage curve by fitting to an exponential equation. Results: Early-assessed radioresponse ranged from 0.001 to 0.106 day -1 (median, 0.021 day -1 ) and late-assessed radioresponse from 0.009 to 0.091 day -1 (median, 0.021 day -1 ), with no significant difference between them (p = 0.1191). The early-assessed radioresponse correlated with the late-assessed radioresponse (R 2 = 0.714, p = 0.0005). Conclusions: Correspondence between early- and late-assessed radioresponse in a series of tumors showing a wide range of radioresponse was not particularly close overall. However, early assessment of radioresponsiveness did seem to be useful for characterizing those tumors with high or low radioresponsiveness

    Full Text Available Concomitant radiochemotherapy is the therapeutic standard for locally advanced (Ib2 to IVa stage FIGO cervical cancer. In the absence of a radiotherapy in many of our Sub-Saharan African countries, surgical resection is the only therapeutic method available in hopes of achieving a definite cure. However, criteria for curative surgery are not always met due to preoperative understaging of most of our patients. In addition to socioeconomic factors, the causes for understaging are numerous. These include the lack of personnel or underqualified personnel and the absence of complete workup to assess the resectability of the tumor, but above all the lack of decision-making through multidisciplinary consultation meetings. This study makes a plea in order to provide our hospitals with qualified personnel and adequate technical platform to allow efficient management of our patients with cervical cancer.

    Cervical intraepithelial neoplasia (CIN) is caused by human papillomavirus (HPV) infection and is the precursor to cervical carcinoma. The completion of the HPV productive life cycle depends on the expression of viral proteins which further determines the severity of the cervical neoplasia. Initiation of the viral productive replication requires expression of the E2 viral protein that cooperates with the E1 viral DNA helicase. A decrease in the viral DNA replication ability and increase in the severity of cervical neoplasia is accompanied by simultaneous elevated expression of E6 and E7 oncoproteins. Here we reveal a novel and important role for the HPV16-E2 protein in controlling host cell cycle during malignant transformation. We showed that cells expressing HPV16-E2 in vitro are arrested in prophase alongside activation of a sustained DDR signal. We uncovered evidence that HPV16-E2 protein is present in vivo in cells that express both mitotic and DDR signals specifically in CIN3 lesions, immediate precursors of cancer, suggesting that E2 may be one of the drivers of genomic instability and carcinogenesis in vivo.

    Full Text Available Basal cell carcinoma (BCC is the most common paraneoplastic disease among human neoplasms. The tumor affects mainly photoexposed areas, most often in the head and seldom appears on genitalia and perigenital region. BCC progresses slowly and metastases are found in less than 0.5% of the cases; however, a considerable local destruction and mutilation could be observed when treatment is neglected or inadequate. Different variants as nodular, cystic, micronodular, superficial, pigment BCC are described in literature and the differential diagnosis in some cases could be difficult. The staging of BCC is made according to Tumor, Node, Metastasis (TNM classification and is essential for performing the adequate treatment. Numerous therapeutic methods established for treatment of BCC, having their advantages or disadvantages, do not absolutely dissolve the risk of relapses. The early diagnostics based on the good knowledge and timely organized and adequate treatment is a precondition for better prognosis. Despite the slow progress and numerous therapeutic methods, the basal cell carcinoma should not be underestimated.

    Hepatocellular carcinoma is a malignancy that predominantly occurs in the setting of cirrhosis. Its incidence is rising worldwide. Hepatocellular carcinoma differs from most malignancies because it is commonly diagnosed on the basis of imaging features alone, without histologic confirmation. The guidelines from the American Association for the Study of Liver Diseases (AASLD) are a leading statement for the diagnosis and staging of hepatocellular carcinoma, and they have recently been updated, incorporating several important changes. AASLD advocates the use of the Barcelona Clinic Liver Cancer (BCLC) staging system, which combines validated imaging and clinical predictors of survival to determine stage and which links staging with treatment options. Each stage of the BCLC system is outlined clearly, with emphasis on case examples. Focal liver lesions identified at ultrasonographic surveillance in patients with cirrhosis require further investigation. Lesions larger than 1 cm should be assessed with multiphasic computed tomography or magnetic resonance imaging. Use of proper equipment and protocols is essential. Lesions larger than 1 cm can be diagnosed as hepatocellular carcinoma from a single study if the characteristic dynamic perfusion pattern of arterial hyperenhancement and venous or delayed phase washout is demonstrated. If the imaging characteristics of hepatocellular carcinoma are not met, the alternate modality should be performed. Biopsy should be used if neither modality is diagnostic of hepatocellular carcinoma. Once the diagnosis has been made, the cancer should be assigned a BCLC stage, which will help determine suitable treatment options. Radiologists require a systematic approach to diagnose and stage hepatocellular carcinoma with appropriate accuracy and precision.

    Purpose: To report the treatment results and rectal/bladder complications of cervical carcinoma radically treated with high-dose-rate intracavitary brachytherapy (HDR-IC). The current policy of using three-fraction scheme was examined. Methods and Materials: Between November 1987 and August 1990, 173 patients with cervical carcinoma were treated with curative-intent radiation therapy. Whole pelvic irradiation was administered with 10-MV X ray. Dose to the central cervix was 40-44 Gy in 20-22 fractions, following by pelvic wall boost 6-14 Gy in three to seven fractions with central shielding. 60 Co sources were used for HDR-IC, and 7.2 Gy was given to Point A for three applications, 1-2 weeks apart. Duration of follow-up was 5-7.8 years. Results: Twenty-eight patients (16%) developed central-regional recurrences. Overall 5-year actuarial pelvic control rate was 83%. By stage, 5-year actuarial pelvic control rates were 94%, 87%, and 72% for Stages IB + IIA, IIB + IIIA, and IIIB + IVA, respectively. Thirty-one patients (18%) developed distant metastasis. Overall 5-year actuarial survival rate was 58%. By stage, 5-year actuarial survival rates were 79%, 59%, and 41% for Stages IB + IIA, IIB + IIIA, and IIIB + IVA, respectively. Sixty-six (38%) and 19 patients (11%) developed rectal and bladder complications, respectively. For rectal complication, the overall actuarial rate was 38% at 5 years. By grade, 5-year actuarial rectal complication rates were 24%, 15%, 4%, and 3% for Grades 1-4, respectively. Overall prevalence of rectal complications was 37% and 14% at 2 and 5 years, respectively. Prevalence of low-grade rectal complication (Grades 1 and 2) was dominant at 2 years (30%), but declined to 8% at 5 years. Prevalence of high-grade, severe rectal complication (Grades 3 and 4) remained steady at 2 and 5 years (7% and 6%, respectively). Five-year actuarial bladder complication was 9%. Five-year prevalence of bladder complication was 2%. Conclusion: Using a three

    .5 years. The duration means of invasive carcinoma stages Ia, Ib and II were 3.0, 2.7 and 3.7 years, respectively. Conclusions: according to the results, CIN 1 and CIN 2 may arise directly from HPV infection and most of these lesions are transient. CIS presented the longest duration and the mean asymptomatic period of cervical neoplasia is 18.2 years. These results were discussed considering the present knowledge of the natural history of cervical carcinoma and other studies on duration of this neoplasia.

    Purpose: Human papillomavirus is a dominant cause of cervical dysplasia with possible transition to cervical cancer. The main purpose of the study was to make a qualified forecast of the potential of vaccination using a bivalent vaccine on the incidence of cervical dysplasia and cervical cancer as well as disease-related mortality in the Slovak Republic. Methods: The method of evaluation was the use of the Markov model that is strictly based on either epidemiological data from official institutions such as the National Oncology Register of the Slovak Republic, Statistic Office of the Slovak Republic, or the data from health insurance companies and the opinion of the experts´ panel of the Society of Gynaecology and Obstetrics. Results: Results obtained by modelling suggest that the introduction of HPV vaccination into the national immunization programme would result in a reduction of at least 84 deaths of women during the monitored period. Every cervical cancer death averted means 31 life years saved on average. Depending on the vaccination coverage in the cohort, HPV vaccination would cause a reduction of registered cervical dysplasia by 26,900 to 131,808 cases, a reduction of registered carcinoma in situ by 1,371 to 6,714 cases, and a decrease of registered invasive cervical carcinoma by 1,645 to 8,058 cases. Conclusion: The results of the analysis confirmed that HPV vaccination in 12-year old girls has the potential to significantly reduce both the incidence of cervical dysplasia and cervical cancer and mortality due to cervical cancer, whereby this form of primary intervention is also cost-effective. Vaccination also enhances the effect of standard secondary prevention realized by age dependant screening. (author)

    To evaluate carcinoma of the cervix using magnetic resonance imaging (MRI), correlate with clinical approach of International Federation of Gynecology and Obstetrics (FIGO) staging system and to study the impact of MRI findings on patient management. Pathologically confirmed, 75 cases of carcinoma cervix referred to our institute from April 2007 to March 2008 were prospectively studied. Clinical FIGO stage was assigned to each patient by gynaecologists blinded to MRI findings. MRI stage (based on FIGO and TNM) was allotted by radiologists blinded to clinicopathological details. For patients who were operated, histopathological stage was taken as gold standard. For patients who were not operated, gynaecologists decided on a gold standard stage based on all available clinical and imaging data. MR staging was correlated with FIGO staging, with focus on significant alterations in treatment strategy caused due to MRI findings. MRI staging had an accuracy of 89.3% (67/75), while clinical FIGO staging had 61.3% (46/75) accuracy. MRI staging and FIGO staging concurred in 65.6% of the patients and differed in 34.4% of the patients. In about 30.6% (23/75) of the patients, there were relevant additional MRI findings not suspected clinically. The common significant MRI findings were detection of pelvic lymphadenopathy and clinically unsuspected bowel/bladder invasion. The management protocol was significantly altered in 86.9% (20/23) of the patients with additional MRI findings constituting 26.6% (20/75) of the total population. MRI is highly accurate in evaluating carcinoma of the cervix. MRI findings significantly altered therapeutic decisions in 26.6% of the patients. MRI should be considered prior to treatment planning in every patient.

    There is currently limited information about human papillomavirus (HPV) genotype distribution in women in the South Pacific region. This study's objective was to determine HPV genotypes present in cervical cancer (CC) and precancers (cervical intraepithelial lesion (CIN) 3) in Fiji. Cross-sectional analysis evaluated archival CC and CIN3 biopsy samples from 296 women of Melanesian Fijian ethnicity (n=182, 61.5%) and Indo-Fijian ethnicity (n=114, 38.5%). HPV genotypes were evaluated using the INNO-LiPA assay in archival samples from CC (n=174) and CIN3 (n=122) among women in Fiji over a 5-year period from 2003 to 2007. Overall, 99% of the specimens tested were HPV DNA-positive for high-risk genotypes, with detection rates of 100%, 97.4% and 100% in CIN3, squamous cell carcinoma (SCC) and adenosquamous carcinoma biopsies, respectively. Genotypes 16 and 18 were the most common (77%), followed by HPV 31 (4.3%). Genotype HPV 16 was the most common identified (59%) in CIN3 specimens, followed by HPV 31 (9%) and HPV 52 (6.6%). Multiple genotypes were detected in 12.5-33.3% of specimens, depending on the pathology. These results indicated that the two most prevalent CC-associated HPV genotypes in Fiji parallel those described in other regions worldwide, with genotype variations thereafter. These data suggest that the currently available bivalent and quadrivalent HPV vaccines could potentially reduce cervical cancers in Fiji by over 80% and reduce precancers by at least 60%.

    Carcinoma of cervix is the most common cancer found among the women of India. Though cervical cytology screening was effective in preventing carcinoma of cervix in developed nations, it is considered unsuitable in developing countries. Recent research has established an etiological link between human papillomavirus infection and carcinoma of cervix. In this review, an attempt is made to answer the question, 'whether carcinoma of cervix can be prevented with human papillomavirus vaccine?' Literature search using Pubmed and Medline was carried out and relevant articles were reviewed. There is ample experimental evidence to show that DNA of human papillomavirus integrates with cervical cell genome. Viral genes E6 and E7 of HPV type 16 and 18 inactivate p53 function and Rb gene, thus immortalize the cervical epithelial cells. Recombinant vaccines blocked the function of E6 and E7 genes preventing development of papillomas in animals. Vaccination with HPV-VLPs encoding for genes of E6 and E7 neutralizes HPV integrated genome of malignant cells of uterine cervix. Based on experimental evidence, it is possible to prevent carcinoma of cervix with human papillomavirus vaccine, Further research is necessary to identify a effective and safe HPV vaccine, routes of administration and characteristics of potential beneficiaries.

    To describe human papillomavirus (HPV) distribution in invasive cervical carcinoma (ICC) from Mali and Senegal and to compare type-specific relative contribution among sub-Saharan African (SSA) countries. A multicentric study was conducted to collect paraffin-embedded blocks of ICC. Polymerase chain reaction, DNA enzyme immunoassay and line probe assay were performed for HPV detection and genotyping. Data from SSA (Mozambique, Nigeria and Uganda) and 35 other countries were compared. One hundred and sixty-four ICC cases from Mali and Senegal were tested from which 138 were positive (adjusted prevalence = 86.8%; 95% CI = 79.7-91.7%). HPV16 and HPV18 accounted for 57.2% of infections and HPV45 for 16.7%. In SSA countries, HPV16 was less frequent than in the rest of the world (49.4%vs. 62.6%; P < 0.0001) but HPV18 and HPV45 were two times more frequent (19.3%vs. 9.4%; P < 0.0001 and 10.3%vs. 5.6%; P < 0.0001, respectively). There was an ecological correlation between HIV prevalence and the increase of HPV18 and the decrease of HPV45 in ICC in SSA (P = 0.037 for both). HPV16/18/45 accounted for two-thirds of the HPV types found in invasive cervical cancer in Mali and Senegal. Our results suggest that HIV may play a role in the underlying HPV18 and HPV45 contribution to cervical cancer, but further studies are needed to confirm this correlation. © 2012 Blackwell Publishing Ltd.

    The delay in detection of premalignant and malignant lesions can have an adverse impact on the outcome of carcinoma cervix. In spite of relatively good healthcare facilities, women in Kerala continue to report in advanced stages of cervical malignancy. To analyze factors associated with delayed reporting and to evaluate awareness about screening and vaccination programs for prevention of carcinoma cervix. A cross-sectional study design was used to evaluate the subjects diagnosed to have carcinoma cervix in the outpatient Department of Obstetrics and Gynecology, Government Medical College, Thrissur, Kerala for a period of two years. One-hundred and fifteen women diagnosed to have invasive carcinoma during the study were evaluated. Data analysis was done and expressed as means and percentages. One-hundred and fifteen women participated in the study. Only 26 (21.7 %) of the subjects were diagnosed in a relatively early stage, i.e., up to stage 2a. Most of them were from families living below poverty line (63.9 %) and were either widowed or divorced (57.3 %). Illiteracy was common (48.9 %) among them, and many (71.3 %) worked as manual laborers. None of the subjects was aware about the availability of screening and vaccination programs for prevention of carcinoma cervix. There is a wide gap between the awareness of availability of healthcare and its proper utilization by the poor. Scaling up of public awareness of preventive programs and the availability of healthcare facilities are essential to enable the timely utilization of such services to facilitate early detection of invasive carcinoma cervix.

    FOXA1 is a major transcription factor involved in the action of human papilloma virus (HPV). However, it has been never studied in HPV-associated tumors. To investigate its expression in cervical and head and neck tumors. 63 cervical carcinomas/dysplasias and 152 head and neck squamous cell carcinomas (HNSCC) were immunohistochemically studied for the expression of FOXA1. 63.1% of cervical SCC and 40.7% of endocervical adenocarcinomas strongly expressed FOXA1. Most (90%) pre-invasive lesions (CIN3 and in situ adenocarcinomas) strongly expressed FOXA1 and this difference from invasive lesions was statistically significant (p=0.005). No association with clinicopathological factors was found. 51.3% of HNSCC expressed FOXA1. In these tumors, FOXA1 expression was associated with the non-keratinizing morphology but not with the HPV/p16 status neither other clinicopathological features. Of normal structures, salivary glands, endocervical glands and basal/parabasal cell layer of squamous epithelium of both uterine cervix and head and neck mucosa, all strongly expressed FOXA1. FOXA1 is expressed by basal cells of squamous epithelium, pre-invasion lesions of the uterine cervix and the head/neck and almost half invasive cervical and head/neck carcinomas, supporting its possible implication in HPV pathogenesis.

    Full Text Available Objective: To study the effect of Twist, Snail and YB-1 gene expression in cervical cancer tissue on cell invasion and epithelial-mesenchymal transition. Methods: Cervical cancer tissue samples and tissue samples adjacent to carcinoma were collected from 138 patients with radical operation for cervical cancer, fluorescence quantitative PCR method was used to detect the mRNA expression of Twist, Snail and YB-1 genes, cell invasion-related genes and epithelial-mesenchymal transition marker genes, the Pearson test was used to analyze the correlation of Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue with cell invasion and epithelial-mesenchymal transition. Results: Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were higher than those in tissue adjacent to carcinoma, the invasion genes STAT3, YAP1, TUG1, FoxM1 and Rab11 mRNA expression were higher than those in tissue adjacent to carcinoma, and the epithelial-mesenchymal transition markers E-cadherin and β-catenin gene mRNA expression were lower than those in tissue adjacent to carcinoma while vimentin gene mRNA expression was higher than that in tissue adjacent to carcinoma. Pearson test showed that Twist, Snail and YB-1 gene mRNA expression in cervical cancer tissue were directly correlated with cell invasion and epithelial-mesenchymal transition. Conclusion: Twist, Snail and YB-1 genes are highly expressed in cervical cancer tissue, and their abnormal expression directly leads to the increased tumor cell invasion activity and the aggravated epithelial-mesenchymal transition.

    Purpose: The aggressiveness of radiation therapy for patients with medically inoperable endometrial carcinoma is controversial. Patients may die of their underlining medical disease before succumbing to cancer. We try to identify certain subgroup of patients who might benefit most from an aggressive approach and also investigate the impact of residual tumor present in dilatation and curettage (D and C) specimen obtained in second intracavitary implant (ICI). Methods and Materials: From 1965 to 1990, 101 patients were treated for clinical clinical Stage I endometrial carcinoma with RT alone due to medical problems. Ages ranged from 39 to 94 years (median 71 years). There were 18 patients with clinical Stage IA and 83 with clinical Stage IB disease. Histology included 44 well-differentiated, 37 moderately differentiated, and 20 poorly differentiated tumors. Radiation therapy consisted of external beam only in 3 patients, ICI alone in 26, whole pelvis plus ICI in 10, and whole pelvis plus split field plus ICI in 62. A second D and C was performed on 26 patients at the time of the second ICI. Minimum follow-up was 2 years (median, 6.3 years). Results: The 5-year actuarial disease-free survival (DFS) for the studied cohort is comparable to the expected survival of an age-matched population. Pelvic control was 100% for Stage IA and 88% for Stage IB with 5-year disease-free survivals of 80 and 84%, respectively. We also observed a greater disassociation of DFS and overall survival among patients older than 75 years (84 and 55%, respectively) than in younger patients (84 and 78%, respectively). This is mainly because older patients succumbed to their medical illness. Well-differentiated disease demonstrated the trend toward a better outcome than moderately or poorly differentiated lesions in Stage IB patients (p 0.05), but not in Stage IA patients. Aggressive radiation therapy approach showed the trend toward a better result in Stage IB patients 75 years of age or younger

  5. The Epidemiology of Human Papillomavirus Infection and Cervical Cancer

    Full Text Available Cervical cancer has been recognized as a rare outcome of a common Sexually Transmitted Infection (STI. The etiologic association is restricted to a limited number of viral types of the family of the Human Papillomaviruses (HPVs. The association is causal in nature and under optimal testing systems, HPV DNA can be identified in all specimens of invasive cervical cancer. As a consequence, it has been claimed that HPV infection is a necessary cause of cervical cancer. The evidence is consistent worldwide and implies both the Squamous Cell Carcinomas (SCC, the adenocarcinomas and the vast majority (i.e. > 95% of the immediate precursors, namely High Grade Squamous Intraepithelial Lesions (HSIL/Cervical Intraepithelial Neoplasia 3 (CIN3/Carcinoma in situ. Co-factors that modify the risk among HPV DNA positive women include the use of oral contraceptives (OC for five or more years, smoking, high parity (five or more full term pregnancies and previous exposure to other sexually transmitted diseases such as Chlamydia Trachomatis (CT and Herpes Simplex Virus type 2 (HSV-2. Women exposed to the Human Immunodeficiency Virus (HIV are at high risk for HPV infection, HPV DNA persistency and progression of HPV lesions to cervical cancer.

    The goal of this retrospective study was to investigate the efficacy and safety of preoperative chemoradiotherapy (NACR) in patients with Stage 2 or Stage 3 esophageal squamous cell carcinoma (SCC). Between 2004 and 2014, a total of 86 patients underwent surgical resection in conjunction with NACR for esophageal SCC at our institute. Thirty-one patients (36.0%) had Stage 2 disease and 55 patients (64.0%) had Stage 3 disease. The median age was 64 (43-81) years. A total of 78 patients received the full NACR regimen. The most common major Grade 3 hematologic toxic effects of NACR were leukopenia and neutropenia (48 cases), while the most common major Grade 3 non-hematologic toxic effect was anorexia (12 cases). One patient died in the hospital and no patients died within 30 days after surgery. A pathological complete response was achieved in 23 cases. Pathological staging (number of cases) was Stage 0 (23), Stage 1 (8), Stage 2 (28), Stage 3 (25), and Stage 4 (2). The 5-year overall survival rate (OS) was 51.0%, and was 83.2% in Stage 2 patients and 29.9% in Stage 3 patients. Preoperative NACR is safe and may improve OS and down-staging rates in patients with esophageal SCC. (author)

    Between November 1981 to May 1985, measurements were made of the exponential regression of 69 cervical nodes from 37 patients with squamous cell carcinoma treated with radiotherapy in the division of clinical oncology, the department of Radiology at the Tokyo Women's Medical College. The volume-halving time (T 1/2(V)) which was calculated in each case was analysed. The results were as follows. 1. T 1/2(V) of oral cavity, lung, hypopharynx and esophagus seemed to be longer than those of oropharynx, uterus, larynx and epipharynx. 2. T 1/2(V) of well differentiated squamous cell carcinoma seemed to be shorter than those of moderately and poorly differentiated squamous cell carcinoma, however no significant difference was found. 3. There were two patterns of initial regression. One half of lymph nodes regressed with an initial shoulder and the other half regressed without it. And T 1/2(V) of regression curve with it was statistically shorter than that without it. 4. There was no significant correlation between T 1/2(V) and the lymph node size. 5. The response rate of lymph node to radiotherapy was higher and the regrowth rate was lower in the fast regression group, compared with those in the slow regression group. (author)

    Surgery remains the treatment of choice in patients with localized bronchogenic carcinoma. Pre-operative identification of inoperability spares the patient from unnecessary surgery. This prospective study was carried out to determine the correctness of judgement regarding a patient's operability or inoperability based on the pre-operative staging of CT scan; to find out the sensitivity, specificity and overall accuracy of the CT scan in estimating tumor description, nodal status and metastatic spread to the chest. Staging was done by 3 senior radiologists aware of the diagnosis. Both the surgical and histopathologic findings and staging were gathered and used as measurement of truth in arriving at the CT scan's accuracy. Overall accuracy rate of CT scan in determining operability or inoperability is 80%; tumor description accuracy of assessment is 87% and nodal status estimation has an accuracy of 60%. Sensitivity of CT scan is assessment of metastatic spread to the chest is 93%. There is no statistically significant difference in the judgement of operability or interpretability by CT scan compared to surgical and histopathologic results. The CT scan is recommended as a valuable tool in the pre-operative staging of patients with bronchogenic carcinoma who are candidates for surgery. (auth.). 21 refs.; 8 tabs

    The aim of this study was to investigate the role of HPV 18 E6 and E7 gene products with respect to radiosensitivity of two cervical carcinoma cell lines. The two cervical carcinoma lines C4-1 and SW 756 were used in which treatment with dexamethasone allows to modulate expression levels of HPV 18 E6 and E7 genes: Upregulation in C4-1, down-regulation in SW 756. Effects of treatment with dexamethasone on plating efficiency and radiosensitivity were assessed using a clonogenic assay. Treatment with dexamethasone increased plating efficiency of the C4-1 cells, but did not affect plating efficiency of SW 756 cells. Treatment with dexamethasone induced enhanced radioresistance in both cell lines. Thus, in C4-1 cells the observed changes in radioresistance correlate to the enhancement in expression of HPV 18 genes E6/E7, whereas in SW 756, a reduced expression correlates negatively with the enhanced radioresistance. (orig./MG) [Deutsch] Das Ziel dieser Studie lag darin, die Rolle der HPV-18-Gene E6 und E7 in bezug auf die Strahlenempfindlichkeit von menschlichen Zervixkarzinomzellen zu untersuchen. Wir verwendeten zwei menschliche Zervixkarzinomzellinien, C4-1 und SW 756, in welchen die Expression der viralen Gene HPV 18 E6 und E7 mit Dexamethason moduliert werden kann: In C4-1 bewirkt die Behandlung mit Dexamethason eine Erhoehung der Expression dieser Gene, in SW 756 eine Verminderung. Die Wirkung auf die Wachstumsfaehigkeit der Zellen und auf die Wachstumshemmung durch die Bestrahlung wurde unter Verwendung eines klonogenen Assays bestimmt. Dexamethason bewirkte eine erhoehte Wachstumsfaehigkeit der C4-1 Zellen, ohne die Wachstumsfaehigkeit der SW-756-Zellen zu beeinflussen, wie schon frueher beschrieben. Die Resistenz beider Zellinien gegenueber Bestrahlung wurde erhoeht. Somit besteht in den C4-1-Zellen eine Korrelation der Expression der viralen Gene mit der Zunahme der Strahlenresistenz, wogegen in den SW-756-Zellen die Abnahme der Expression im Gegensatz zu

    Background and purpose: To determine the effect of radiotherapy in HIV seropositive cervical cancer patients, tumour response and toxicity and compliance of patients to the treatment. Patients and methods: This study is a retrospective review of 42 HIV seropositive patients diagnosed with carcinoma cervix, between 1997 and 2003 at the Tata Memorial Hospital. The age and symptoms of presentation, clinical stage, response, compliance and tolerance to radiotherapy were studied. Results: Mean age at presentation was 41 years. All patients presented with the symptoms of cervical disease. Of these patients 31(74%) patients had 'Karnofsky Performance Scale' (KPS) more than 80%. Twenty-one (50%) of the patients were of Stage IIIb-IVa. Thirty-two (76%) were started on radiotherapy with radical intent. Compliance to radiotherapy was poor with 24% patients discontinuing after few fractions of radiotherapy. Seven (17%) patients were given palliative radiotherapy. Twenty-two patients completed prescribed radical radiotherapy and 50% of these achieved complete response. Grade III-IV acute gastrointestinal toxicity was seen in 14% of the patients, and grade III acute skin toxicity was seen in 27% of patients, leading to treatment delays. There was good relief of symptoms in patients treated with palliative intent. Conclusions: Radiotherapy is effective in this set of patients. Palliative fractionation schedules are effective for patients with poor performance status and locally advanced cancers in relieving the symptoms related to carcinoma cervix. An emphasis should be given to the increased acute mucosal and skin toxicity and to improving compliance and clinical outcome of these patients

    Cervical cancer is one of the most common cancers in women. The purpose of this article is to analyze the main diagnostic and treatment strategies for all stages and recurrences of cervical cancer. The article reviews the epidemiological situation, clinical features, diagnostic procedures for detection of this tumor and for evaluation of the dissemination of the disease, staging criteria, TNM (Tumor, Nodes, Metastases) and FIGO (Federation Internationale de Gynecologie et d'Obstetrique) classification, as well as treatment and prognosis. Surgical treatment (radical type II or III hysterectomy and Iymphadenectomy) for early stage I and IIA cervical cancer is the main treatment method. Delivery of adjuvant postoperative radiation therapy or concomitant chemoradiation depends on the prognostic factors (tumor penetration to cervical tissues, Iymphovascular invasion, tumor invasion to paracervical tissues, and surgical margins). For treatment of more advanced stages of cervical cancer (IIB, IIIA, IIIB, IVA) concomitant chemoradiation: external beam radiotherapy with chemotherapy and brachytherapy is used. Description of the treatment guidelines for each stage of cervical cancer is given in this article. These guidelines are useful for good treatment practice. (author)

    Introduction: Nodal metastases in cervical cancer have prognostic implications. Imaging is used as an adjunct to clinical staging for evaluation of nodal metastases. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) has an advantage of superior resolution of its CT component and detecting nodal disease based on increased glycolytic activity rather than node size. But there are limited studies describing its limitations in early stage cervical cancers. Objectiv...

    Background and purpose: The aim of this retrospective study was to analyze the outcome of patients with locally advanced cervical carcinoma treated by adjuvant radiochemotherapy and to determine risk factors for local and distant relapse. Furthermore, acute and late effects of treatment were recorded. Patients and methods: A total of 72 patients with FIGO stages I-III cervical carcinoma were treated by radical hysterectomy, pelvic lymphadenectomy, and postoperative radiochemotherapy. Only patients with positive pelvic lymph nodes, parametrial involvement, positive margins, or tumor bulk were eligible. Patients were irradiated with a standard pelvic field (50.4 Gy in 28 fractions). The majority of patients received platinum-based chemotherapy. Results: After a median follow-up of 37 months, estimated 1-, 2-, and 4-year disease-free survival (DFS) and overall survival (OS) rates were 89%, 80%, 68% and 95%, 88%, 76%, respectively. Nine of the 72 patients had pelvic recurrences including only 1 isolated local failure; 23 of the 72 patients presented with distant relapse. The majority of relapses occurred within the first 3 years after adjuvant treatment. The number of positive pelvic lymph nodes (> 1) was the strongest prognostic factor for DFS. Treatment was well tolerated with transient acute hematologic ({proportional_to}30%) and gastrointestinal ({proportional_to}30%) grade 3 toxicity. Small bowel obstruction ({proportional_to}6%) was the only important late sequelae. Conclusion: Adjuvant radiochemotherapy in patients with advanced cervical cancer and several risk factors is highly effective to prevent local relapse. Future efforts to improve outcome should be placed on improvement of systemic control especially in subgroups with high-risk features for distant relapse. Combined treatment was well tolerated with moderate acute and late toxicity. (orig.)

    We present the results of a two-stage biological model of lung carcinogenesis in rats. The histogenesis of these tumors was examined, and DNA content of lung cells was measured by flow cytometry during the evolving neoplastic stage. Tumors were induced in rat lungs after radon inhalation (1600 WLM) followed by a promoter treatment; six intramuscular injections of 5,6-benzoflavone (25 mg/kg of body weight/injection) every 2 wk. Less than 3 mo after the first injection of benzoflavone, squamous cell carcinoma was observed in the lungs of all rats exposed to radon. The preneoplastic lesions gradually developed as follows: hyperplastic bronchiolar-type cells migrated to the alveoli from cells that proliferated in bronchioles and alveolar ducts; initial lesions were observed in almost all respiratory bronchioles. From some hyperplasias, epidermoid metaplasias arose distally, forming nodular epidermoid lesions in alveoli, which progressed to form squamous papilloma and, finally, epidermoid carcinomas. The histogenesis of these experimentally induced epidermoid carcinomas showed the bronchioloalveolar origin of the tumor. This factor must be considered when comparing these with human lesions; in humans, lung epidermoid carcinomas are thought to arise mainly in the first bronchial generations. The labeling index of pulmonary tissue after incorporation of 3 H-thymidine by the cells was 0.2% in control rats. This index reached a value of 1 to 2% in the hyperplastic area of the bronchioles and 10 to 15% in epidermoid nodules and epidermoid tumors, respectively. DNA cytometric analysis was performed on cell suspensions obtained after enzymatic treatment of paraffin sections of lungs from rats sacrificed during different stags of neoplastic transformations. Data showed the early appearance of a triploid cell population that grew during the evolution of nodular epidermoid lesions to epidermoid carcinomas

    To evaluate the screening efficacy and importance of atypical squamous cells and atypical glandular cells in predicting subsequent cervical cancer risk. This national cohort study in Taiwan analyzed associations between Pap test screening frequency and findings in 1995-2000 and subsequent risk of squamous cell carcinoma and adenocarcinoma after 2002. Women aged 30 years or older in 1995 without a cervical cancer history were included. Multivariate-adjusted hazard ratios and their 95% confidence intervals (CIs) were assessed using Cox regression analysis. During a total follow-up of 31,693,980 person-years in 2002-2008, 9,471 squamous cell carcinoma and 1,455 adenocarcinoma cases were newly diagnosed, resulting in 2,067 deaths. The risk of developing and dying from squamous cell carcinoma decreased significantly with increasing attendance frequency between 1995 and 2000 (all P values for trend1995-2000 had 0.69-fold and 0.35-fold decrease in incidence and mortality of adenocarcinoma, respectively, compared with women who never attended any screenings. Abnormal cytologic findings were significant predictors of the incidence and mortality of cervical cancers. The adjusted hazard ratio (95% CI) of developing squamous cell carcinoma was 29.94 (22.83-39.25) for atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions, and the adjusted hazard ratio (95% CI) of developing adenocarcinoma was 49.43 (36.49-66.97) for atypical glandular cells. Significant reductions in cervical adenocarcinoma occurred in women who attend three or more annual screenings in 6 years. High-grade atypical squamous cells and atypical glandular cells are important predictors of subsequent adenocarcinoma and squamous cell carcinoma. II.

    To assess the relation between expressions of human nonmetastatic clone 23 (nm23-H1) and p53 in cervical cancer, their relationships with lymph node metastasis, and further to examine their predictive of lymph node metastases. nm23-H1 and p53 expression profiles were visualized by immunohistochemistry in early-stage cervical cancer specimens. Immunoreactivities of nm23-H1 and p53 were disassociated. The independent variables related with lymph node metastases were grade of cancer cell differentiation (p not good predictors of lymph node metastases in early-stage cervical cancer patients. However, stromal invasion and cell differentiation can predict lymph node metastasis.

    Highlights: • Gold nanoparticles (AuNPs) have been synthesized using Podophyllum hexandrum L. • AuNPs induces the oxidative stress to cell death in human cervical carcinoma cells. • It activates the caspase-cascade to cellular death. • It is actively blocks G2/M phase of cell cycle. - Abstract: Current prospect of nanobiotechnology involves in the greener synthesis of nanostructured materials particularly noble metal nanoparticles for various biomedical applications. In this study, biologically (Podophyllum hexandrum L.) synthesized crystalline gold nanoparticles (AuNPs) with the size range between 5 and 35 nm were screened for its anticancereous potential against human cervical carcinoma cells (HeLa). Stoichiometric proportion of the reaction mixture and conditions were optimized to attain stable nanoparticles with narrow size range. Different high throughput techniques like transmission electron microscope (TEM), X-ray diffraction (XRD) and UV–vis spectroscopy were adopted for the physio-chemical characterization of AuNPs. Additionally, Fourier transform infrared spectroscopy (FTIR) study revealed that the water soluble fractions present in the plant extract solely influences the reduction of AuNPs. Sublimely, synthesized AuNPs exhibits an effective in vitro anticancer activity against HeLa cells via induction of cell cycle arrest and DNA damage. Furthermore, it was evidenced that AuNPs treated cells are undergone apoptosis through the activation of caspase cascade which subsequently leads to mitochondrial dysfunction. Thereby, this study proves that biogenic colloidal AuNPs can be developed as a promising drug candidature for human cervical cancer therapy

    We aimed to investigate the possibility of an association between a stem-like hallmark and radiotherapeutic sensitivity in human cervical carcinoma cells. Side-population (SP) cells and non-SP (NSP) cells in HeLa cells were isolated using flow cytometry and Hoechst 33342 efflux. We performed Western blot analysis to evaluate the expression of stem cell markers (CXCR4, Oct3/4, CD133, and SOX2) and apoptosis markers after irradiation. In addition, SP and NSP cells were injected into nude mice and we assessed subcutaneous tumor formation. To examine tolerance of irradiation, colony formation and apoptosis change were confirmed in the SP and NSP cells. SP cells showed a higher expression of CXCR4, Oct3/4, CD133, and SOX2 than NSP cells. The colony size of SP cells cultured on non-coated dishes was larger than that of NSP cells, and NSP cells were easily induced to undergo apoptosis. SP cells tended to form spheroids and showed a higher level of tumorigenicity compared with NSP cells. In addition, nude mice inoculated with SP cells showed greater tumor growth compared with NSP cells. SP cells showed a higher tumorigenicity and lower apoptotic potential, leading to enhanced radiotolerance. Tumor SP cells showed higher-level stem-cell-like characters and radioresistance than NSP cells. SP cells may be useful for new therapeutic approaches for radiation-resistant cervical cancer. © 2014 The Authors.
