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.

Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

Full Text Available Background. Sarcomatoid squamous cell carcinoma is a rare and aggressive form of cervical cancer. We report a case of metastatic sarcomatoid squamous cell carcinoma (SSCC of cervix that presented with an anterior chest wall mass. Case. A 43-year-old Hispanic female presented with a two-month history of a central chest wall mass. The patient’s only past medical history was SSCC of the cervix, stage IIB, diagnosed two years priorly. She underwent neoadjuvant chemoradiation therapy (CRT with cisplatin followed by radical hysterectomy. Surgical margins were positive which led to adjuvant CRT with carboplatin and paclitaxel. PET scan 4 months after the postoperative treatment was negative for recurrence and metastatic disease. On current presentation, the CT chest revealed anterior mediastinal destructive soft tissue mass involving sternum, and the biopsy showed SSCC. The patient received palliative radiation therapy to her chest with improvement in pain and ability to swallow. After discussing the prognosis she refused further chemotherapy and decided on hospice care. Conclusion. Despite good response to first-line therapy, SSCC tends to recur early and does not respond to second-line therapy. Radiation therapy seems to be the most effective modality for treatment, but randomized controlled trials of therapy are impractical.

the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

This paper reports the results of a study of risk factors for recurrence in non-irradiated sites in patients with squamous cell carcinoma of the uterine cervix who received postoperative irradiation. It also discusses clinical experience with such patients, particularly those with a poor prognosis, based on a review of the literature. The study was conducted at the National Shikoku Cancer Center in 62 patients with squamous cell carcinoma of the uterine cervix (mean age=50.5, range=30-66) who received 10 MeV postoperative irradiation with a Linac between 1981 and 1990. An analysis was performed in terms of sites and times of recurrence, risk factors for distant metastasis, and groups at high risk for distant metastasis. Based on the results of the study as well as the review of the literature, it was concluded that squamous cell carcinoma of the uterine cervix is sensitive to radiation therapy and that the clinical outcome of local treatment is satisfactory. However, systemic chemotherapy should be considered for patients who are suspected of having minute distant metastasis at the time of surgical operation, i.e., those with moderate to severe vascular space invasion, multiple lymph node metastasis, parametrium infiltration, and/or endometrial infiltration.

Immune competence was evaluated in 43 patients of carcinoma breast, 77 patients of cancer cervix, as compared to 30 normal healthy women. The study also included 25 women from the two carcinoma groups, who had undergone radiotherapy. A reduction in the white blood cell count, absolute lymphocyte count, active T-cell count and absolute T-cell count were observed in patients with carcinoma of the breast and cervix prior to irradiation. Radiation therapy resulted in a striking reduction of all the three parameters in both the carcinoma groups. Substantial recovery was observed within a year after cessation of therapy. Increased number of peripheral B lymphocytes was observed in carcinoma of the breast as well as the cervix prior to irradiation. At completion of radiation, the number decreased markedly in both groups of patients. Gradual recovery took place within a year. The reduction in lymphocyte numbers and its subpopulations could not be attributed to thymic irradiation, since patients receiving pelvic and mediastinal (including thymic) radiotherapy showed similar changes.

Computed tomography(X-CT) of squamous cell carcinoma of the uterine cervix was done before and after radiotherapy in forty cases. Changes on X-CT images and its relationship to local control are discussed. Volume of the cervix measured by X-CT is turned out to be a very important factor in radiotherapy of carcinoma of the uterine cervix. 2 cases whose volumes of the cervix exceed 100 cc before radiotherapy failed to obtain local control (p 0.005). After radiotherapy in 6 cases whose volumes of the cervix were more than 20 cc, 5 cases of all failed in local and in 33 cases whose volumes of the cervix were less than 20 cc, 32 cases of all obtained 1 year local control (p < 0.001). In about half cases in which contrast medium was administered low density areas in cervix were observed, in most of all this low density area disappeared after radiotherapy. In the cases in which this low density remained, 3 out of 4 cases failed locally. (author)

Purpose: To assess the predictive value of pretreatment proliferative activity of epidermoid cervix carcinoma cells with respect to short- and long-term results of radiotherapy. Methods and Materials: The proliferative activity of 25 epidermoid cervix carcinomas was evaluated as the immunofluorescent labelling index (LI) by rabbit antithymidine antibodies reacting specifically with single-stranded DNA of replication forks in S-phase cells. The short-term clinical outcome was estimated at 3-6 months after treatment by visual and palpatory examination. Three-year follow-up data were obtained through hospital charts and correspondence with referring physicians for only 19 patients. Results: There was no statistically significant association between LI and such conventional prognostic factors as clinical stage. The LI value of cervix carcinomas was significantly associated with complete regression at 3-6 months after radiotherapy and 3-year disease-free survival. Complete regression at 3-6 months was observed in 87.5% patients with fast proliferating tumors (LI > 7.0%), and only in 41.2% patients with slowly proliferating tumors (p = 0.03). Probability of 3-year disease-free survival was 85.7% in patients with fast proliferating tumors and 50.0% in those with slowly proliferating tumors (p = 0.05). Conclusions: The immunofluorescent LI of epidermoid cervix carcinoma is able to provide prognostic information on short-term tumor response to radiotherapy and disease-free survival

The human uterine cervix carcinoma is one of the most well-known malignancy reproductive system cancers, which threatens women health globally. However, the mechanisms of the oncogenesis and development process of cervix carcinoma are not yet fully understood. Long non-coding RNAs (lncRNAs) have been proved to play key roles in various biological processes, especially development of cancer. The function and mechanism of lncRNAs on cervix carcinoma is still rarely reported. We selected 3 cervix cancer and normal cervix tissues separately, then performed lncRNA microarray to detect the differentially expressed lncRNAs. Subsequently, we explored the potential function of these dysregulated lncRNAs through online bioinformatics databases. Finally, quantity real-time PCR was carried out to confirm the expression levels of these dysregulated lncRNAs in cervix cancer and normal tissues. We uncovered the profiles of differentially expressed lncRNAs between normal and cervix carcinoma tissues by using the microarray techniques, and found 1622 upregulated and 3026 downregulated lncRNAs (fold-change>2.0) in cervix carcinoma compared to the normal cervical tissue. Furthermore, we found HOXA11-AS might participate in cervix carcinogenesis by regulating HOXA11, which is involved in regulating biological processes of cervix cancer. This study afforded expression profiles of lncRNAs between cervix carcinoma tissue and normal cervical tissue, which could provide database for further research about the function and mechanism of key-lncRNAs in cervix carcinoma, and might be helpful to explore potential diagnosis factors and therapeutic targets for cervix carcinoma.

The standard of care for locally advanced carcinoma of uterine cervix is concurrent chemoradiation therapy followed by intracavitary brachytherapy, when there is para-aortic lymphadenopathy, radiation field needs to be extended to para-aortic region. In the latter case dose limiting organs are spinal cord, kidneys and small intestine. We present a challenging case of FIGO IVB squamous cell carcinoma of cervix and a pelvic kidney. This patient received chemoradiation to pelvis and para-aortic field, brachytherapy was not performed as patient already had undergone attempted hysterectomy. Treatment, outcome and challenges encountered in this case are presented and literature is reviewed. (author)

Peculiarities of immune status in uterine cervix carcinoma patients

On the basis of investigating the peripheral blood lymphocytes the immunologic state in 81 patients with uterine cervix carcinoma is estimated. It is established that there is a considerable decrease of indices in the T-immune system in patients with uterine cervix carcinoma. The detection of reductions in the immunogram indices in the initial stage plays a definte diagnostic role in the detection of metastases, permits to forecast the process generalization, and consequently, to determine the treatment tactics. It is established that under the effect of combined radiation treatment the T-system is mostly injured. Consequently, pronounced postradiation depression is prognostically unfavourable. The examination of another group of patients has shown that the probability of development of lymphogenic metastases in uterine cervix carcinoma is mainly determined by immuno-morphological peculiarities of regional lymph nodes [ru

A group of patients with uterine cervix carcinoma with metastatic indices in regional lymphatic vessels detected on lymphograms is studied. It is established that after radiation treatment the relative resistance of lymphogenic metastases to the ionizing radiation is found in 14.9% patients. Extraperitoneal removal of regional lymphatic collectors after a complete course of combined radiation therapy in patients with uterine cervix carcinoma with histologically proved metastases improves 3-year results of survival up to 40%. In the case of multiple and bilateral metastatic injury of regional lymph nodes the therapeutic value of extraperitoneal lymphadenectomy reduces sharply. The diagnostic value of X-ray contrast lymphography not only for defining regional metastases, but for planning and carrying out the treatment of patients with uterine cervix carcinoma is pointed out [ru

A selected group of 136 patients with Stage I squamous cell carcinoma of the cervix was treated in six naval hospitals during the period 1957--1965 using a three-stage combined radiation therapy and surgery protocol. Treatment consisted of two radium applications to the cervix, followed in 6 weeks by extraperitoneal lymphadenectomy. If the lymph nodes were tumor-negative, simple hysterectomy in 3 to 6 months completed the protocol. If the nodes were tumor-positive, a course of external pelvic irradiation was given with midline shielding. The incidence of positive nodes was 9.6 percent. Actuarial survival for all patients was 89.4 percent, comparable to the rate obtained by radical surgery or radiation alone. Postoperative and postradiation complications were minimal, with no urinary or bowel fistulas. There was no operative mortality

Uterine cervix carcinoma is the second most common female malignancy worldwide and a major health problem in Mexico, representing the primary cause of death among the Mexican female population. High risk human papillomavirus (HPV) infection is considered to be the most important risk factor for the development of this tumor and cervical carcinoma derived cell lines are very useful models for the study of viral carcinogenesis. Comparative Genomic Hybridization (CGH) experiments have detected a specific pattern of chromosomal imbalances during cervical cancer progression, indicating chromosomal regions that might contain genes that are important for cervical transformation. We performed HPV detection and CGH analysis in order to initiate the genomic characterization of four recently established cervical carcinoma derived cell lines from Mexican patients. All the cell lines were HPV18 positive. The most prevalent imbalances in the cell lines were gains in chromosomes 1q23-q32, 3q11.2-q13.1, 3q22-q26.1, 5p15.1-p11.2, this alteration present as a high copy number amplification in three of the cell lines, 7p15-p13, 7q21, 7q31, 11q21, and 12q12, and losses in 2q35-qter, 4p16, 6q26-qter, 9q34 and 19q13.2-qter. Analysis of our present findings and previously reported data suggest that gains at 1q31-q32 and 7p13-p14, as well as losses at 6q26-q27 are alterations that might be unique for HPV18 positive cases. These chromosomal regions, as well as regions with high copy number amplifications, coincide with known fragile sites and known HPV integration sites. The general pattern of chromosomal imbalances detected in the cells resembled that found in invasive cervical tumors, suggesting that the cells represent good models for the study of cervical carcinoma

Full Text Available Cervical carcinoma is the most common malignancy of the female genital tract and represents the second most common malignancy in women worldwide. Histologically 85 to 90% of cervical cancers are squamous cell carcinoma. Osteoclastic giant cell rich squamous cell carcinoma is an unusual histological variant of which only 4 cases have been reported. We present the case of a 49-year-old woman with a 6-month history of irregular vaginal bleeding. Examination revealed a 2.7 cm polypoid mass in the anterior lip of the uterine cervix. The patient underwent hysterectomy with bilateral salpingo-oophorectomy. Microscopically the tumor was composed of infiltrative nests of poorly differentiated nonkeratinizing squamous cell carcinoma. Interspersed in between these tumor cells were numerous osteoclastic giant cells with abundant eosinophilic cytoplasm devoid of nuclear atypia, hyperchromatism, or mitotic activity. Immunohistochemistry was performed; CK and P63 were strongly positive in the squamous component and negative in the osteoclastic giant cells, while CD68 and Vimentin were strongly positive in the giant cell population and negative in the squamous component. The patient received chemo- and radiotherapy for recurrent disease identified 3 months later on a follow-up CT scan; 7 months after the surgical procedure the patient is clinically and radiologically disease-free.

The results of isotope renography and intravenous pyelography in 420 patients with carcinoma of the uterine cervix

A group of women with carcinoma of the cervix was studied by renography and i.v. pyelography. The incidence of renal and urinary tract disorders detected by these tests increased as did the stage of the disease, being 17.1% with Stage I carcinoma of the cervix, 27.8% with Stage II carcinoma of the cervix, 47% with Stage III carcinoma of the cervix, and 83.3% in Stage IV carcinoma of the cervix. In patients with Stage I and Stage II carcinoma of the cervix, those selected for radiotherapy had twice the incidence of abnormal renograms as those selected for surgery. This difference probably reflected a higher incidence of medical disorders affecting renal and urinary tract function in those considered unfit for surgery. We believe that renograms should be used routinely as a screening test in patients with carcinoma of the cervix. (orig.) [de

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

Dysplastic Ichthyosis Uteri-like changes of the entire endometrium associated with a squamous cell carcinoma of the uterine cervix

Full Text Available Abstract Ichthyosis uteri is an exceedingly rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium. Originally described as an endometrial response to iatrogenically-introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium. We describe herein a heretofore undescribed example of a moderately differentiated squamous cell carcinoma of the uterine cervix associated with extensive ichthyosis uteri-like changes of the entire adjacent endometrium. Additionally, the squamous epithelium of the latter also showed multifocal changes diagnostic of a low-grade squamous intraepithelial lesion. The potential genesis of this composite of findings is discussed, as is the neoplastic potential of ichthyosis uteri. It is concluded that a squamous cell carcinoma of the cervix extended proximally into the endometrium, and that there was a colonization of a pre-existing ichthyosis uteri by associated human papillomavirus. The possibility of significant cervical pathology should be considered when plaques of squamous epithelium with low grade dysplastic changes are identified in an endometrial biopsy or curettage.

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

To evaluate the significance of squamous cell carcinoma antigen (SCC) and carcinoembryonic antigen (CEA) as tumor markers in uterine cervix carcinoma. In 22 patients with histologically proven primary squamous cell carcinoma of uterine cervix, tumor volume was checked either by using MRI (in 20 patients) or ultrasound (in 2 patients). Pre-treatment serum SCC levels were checked in 22 patients and CEA levels in 21 patients. After curative radiotherapy, post-treatment SCC and CEA were checked regularly. SCC was raised in 68.2% and CEA was raised in 19.0% before treatment. The coefficient of correlation between tumor volume and pre-reatment SCC was 0.59382 when one extremely deviated case was excluded. And there was no correlation between tumor volume and CEA. After the treatment, SCC was raised in 9.1% and CEA was raised in 4.8%. In further follow up measurement, raise of SCC was associated with clinical relapse or persistence of disease. The specificity of raised SCC level in association with recurrent or persistent disease was 93.8%. The sensitivity in association with recurrent or persistent disease was 100%. The positive predictive values was 85.7%. The median lead time for recurrence was 1.2 months. Both SCC and CEA were good tumor markers for monitoring treatment effect in patients with raised pre-treatment levels. But the sensitivity of pretreatment CEA was low, while that of pretreatment SCC was high. And there was no additional gain by adding CEA measurements to SCC measurements.

The positive predictive values was 85.7%. The median lead time for recurrence was 1.2 months. Both SCC and CEA were good tumor markers for monitoring treatment effect in patients with raised pre-treatment levels. But the sensitivity of pretreatment CEA was low, while that of pretreatment SCC was high. And there was no additional gain by adding CEA measurements to SCC measurements

Apparatus for treating carcinoma of the uterine cervix

Disclosed is an apparatus for treating carcinoma of the uterine cervix by judiciously applying radioactive material immediately adjacent the uterine cervix for an extended period of time empirically determined by the radiologist. The novel apparatus comprises three radioactively chargeable components including a central tubular tandem vaginally insertable longitudinally into the uterine cervix and two non-lineal tubular ovoidal assemblies longitudinally locatable at the cervix and positioned laterally between the respective vaginal walls and the uterine cervix. The ovoidal assemblies are conveniently removably and pivotably connected to the central tandem component externally of the vaginal along the sagittal plane through a novel adapter member whereby the radioactively chargeable ovoidal assemblies tend to remain within a laterally extending plane located substantially midway the transversely separated vasicovaginal and rectovaginal septa, even though the patient periodically shifts her reclining posture during the extended treatment by said vaginally protruding apparatus

Full Text Available Isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. We describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases tothe bony calvarium as the sole site of metastasis. The patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, FIGO stage IIIb, whose initial treatement was chemoradiation therapy. After 22 sessions of external-beam radiation,she developed headaches. On physical examination she had skull bone tenderness. On plain skull X-ray, there were osteolytic bony lesions. Brain MRI showed multiple enhancing skull bone metatstses. Eventually, a whole body bone scintigraphy revealed isolated diffuse increased activity in the bony calvarium. In the literature review, wefound only three similar cases of cervical cancer with scalp metastases and involvement of the bony calvarium.

Cancer of cervix is the second most common cancer worldwide among women. Several treatments related protocols of radiotherapy have been followed over few decades in its treatment for evaluating the response. These physical doses varying on the basics of fractionation size, dose rate and total dose needed to be indicated as biological effective dose (BED) to rationalize these treatments. The curative potential of radiation therapy in the management of carcinoma of the cervix is greatly enhanced by the use of intracavitary brachytherapy. Successful brachytherapy requires the high radiation dose to be delivered to the tumor where as minimum radiation dose reach to surrounding normal tissue. Present study is aimed to evaluate biologically effective dose in patients receiving high dose-rate brachytherapy plus external beam radiotherapy based on tumor cell proliferation values in cancer of the cervix patients. The study includes 30 patients' data as a retrospective analysis. In addition determine extent of a dose-response relationship existing between the biological effective dose at Point A and the bladder and rectum and the clinical outcomes

Dependence of radiotherapeutic results on tumor size in patients with cervix uteri carcinoma

Gabelov, A.A.; Zharinov, G.M.

1981-01-01

A method is suggested that permits specifying the primary tumor size on the basis of clinical examination of patients with cervix uteri carcinoma. The values of tumor size have been correlated with long-term results of concomitant radiotherapy in 1358 patients with cervix uteri carcinoma. The data obtained have shown that the primary tumor size is a factor that determines to a large extent radiotherapeutic results in patients with cervix uteri carcinoma. The specification of tumor size values makes it possible to considerably lessen prognostic uncertainty of present-day staging classifications. The structure of radiotherapeutic failures also turned out to be closely associated with the primary tumor size

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

This is a retrospective analysis of 148 patients with histologically proven carcinoma of the cervix, stage III, treated with irradiation. All patients received external irradiation with cobalt 60 followed by intracavitary radium application. The median age was 55 years. Squamous cell carcinoma was found in 96.5% of the cases. The 8-year actuarial survival rate was 41%. Bilateral parametrial invasion proved to be a strong prognostic factor. Patients with unilateral disease had a survival rate of 43% whereas in those with bilateral involvement it was only 15% (P less than 0.005). The total pelvic failure rate was 29.5%. The overall incidence of distant metastasis was 11%. The complication rate (minor and major complications) was high, with vaginal stenosis (22.5%), proctitis (21.5%), cystitis (13.5%), and fistulae (4%) occurring in 33, 32, 20, and 6 patients, respectively. New treatment modalities are urgently needed for advanced carcinoma of the cervix. Bilateral parametrial involvement is an unfavorable prognostic factor and this should be kept in mind when designing new protocols

Cervix carcinomas: place of intensity-modulated radiotherapy

Barillot, I.

While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

Gill, J K; Rohatgi, V K; Lahiri, B; Aggarwal, B M [S.N. Medical Coll., Agra (India)

1978-05-01

Rectal biopsy was done in 39 follow-up cases of squamous cell carcinoma of cervix treated with radiotherapy who clinically presented as cases of radiation proctitis. On histological examination, definite evidence of radiation injury was found in 23 cases. In rectal mucosa, radiation ulcers, broken epithelial lining, glandular atrophy, inflammatory cell infiltration, and edema of stroma were seen. Muscularis mucosa was either intact or partially broken. In submucosa, blood vessels showed endarteritis, plasma cell infiltration, fibrinoid necrosis, and hyalinization of vessel wall. In a few cases, hyalinization, edema, and vacuolation of muscle fibres were seen in muscle layer. In one case, squamous cell carcinoma of rectum was diagnosed. During follow-up examinations no complication due to rectal biopsy was observed.

The association between invasive cervical carcinoma and human papillomavirus (HPV) has now been established beyond doubt, but this is not necessarily a direct-and-effect association. To assess the causality of HPV, we analyzed HPV genomes in squamous cell carcinomas (SCCS) of the uterine cervix by both blot hybridization and PCR. Genital HPV sequences were found in 231 (79%) of 294 SCCs by blot hybridization with more than five copies of entire HPV genomes identified in some cases including HPV 16 (92 cases), HPV 58 (32 cases), and HPV 52 (24 cases). By PCR-direct sequence analysis in 250 of 294 SCCs, genital HPV sequences were found in 240 samples (96%). The partial L1 sequences of HPV 16 were identified in 123 cases, and those of HPVs 18 and 31 were found in 24 and 20 cases, respectively. In addition, multiple HPV types were identified in 29 (12%) of 250 SCCs, and the HPV copy number, detected by PCR only, was less than 0.05. Marked discrepancies were therefore evident between the two analytical techniques. In this report, we discuss the causality of HPV for SCC with regard to the length of the viral genome, the amount of viral DNA, and multiple HPVs in single SCCs

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.

Adenoid basal hyperplasia is an underrecognized cervical lesion, resembling adenoid basal carcinoma, except the absence of deep invasion into the stroma. We report a series of 10 cases, all extending less than 1 mm from the basement membrane. Our results support the hypothesis that adenoid basal hyperplasia arises from reserve cells of the cervix. Lesions were found close to the squamocolumnar junction, in continuity with the nearby subcolumnar reserve cells. They shared the same morphology and immunoprofile using a panel of 4 antibodies (keratin 5/6, keratin 14, keratin 7 and p63) designed to differentiate reserve cells from mature squamous cells and endocervical columnar cells. We detected no human papillomavirus infection by in situ hybridization targeting high-risk human papillomavirus, which was concordant with the absence of immunohistochemical p16 expression. We demonstrated human papillomavirus infection in 4 (80%) of 5 adenoid basal carcinoma, which is in the same range as previous studies (88%). Thus, adenoid basal hyperplasia should be distinguished from adenoid basal carcinoma because they imply different risk of human papillomavirus infection and of subsequent association with high-grade invasive carcinoma. In our series, the most reliable morphological parameters to differentiate adenoid basal hyperplasia from adenoid basal carcinoma were the depth of the lesion and the size of the lesion nests. Furthermore, squamous differentiation was rare in adenoid basal hyperplasia and constant in adenoid basal carcinoma. Finally, any mitotic activity and/or an increase of Ki67 labeling index should raise the hypothesis of adenoid basal carcinoma. Copyright © 2012 Elsevier Inc. All rights reserved.

Purpose: To study the outcomes of patients with adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix primarily treated with radiotherapy (RT), identify the prognostic factors, and evaluate the efficacy of concurrent chemoradiotherapy (CCRT) or salvage surgery. Methods and Materials: A total of 148 patients with Stage I-IVA AC/ASC of cervix after full-course definitive RT were included. Of the 148 patients, 77% had advanced stage disease. Treatment failure was categorized as either distant or local failure. Local failure was further separated into persistent tumor or local relapse after complete remission. The effectiveness of CCRT with cisplatin and/or paclitaxel was examined, and the surgical salvage rate for local failure was reviewed. Results: The 5-year relapse-free survival rate was 68%, 38%, 49%, 30%, and 0% for those with Stage IB/IIA nonbulky, IB/IIA bulky, IIB, III, and IVA disease, respectively, and appeared inferior to that of those with squamous cell carcinoma of the cervix treated using the same RT protocol. Incomplete tumor regression after RT, a low hemoglobin level, and positive lymph node metastasis were independent poor prognostic factors for relapse-free survival. CCRT with weekly cisplatinum did not improve the outcome for our AC/ASC patients. Salvage surgery rescued 30% of patients with persistent disease. Conclusion: Patients with AC/ASC of the cervix primarily treated with RT had inferior outcomes compared to those with squamous cell carcinoma. Incomplete tumor regression after RT was the most important prognostic factor for local failure. Salvage surgery for patients with persistent tumor should be encouraged for selected patients. Our results did not demonstrate a benefit of CCRT with cisplatin for this disease.

External irradiation and brachytherapy are curative in the treatment of carcinoma of the cervix. The aim of radiotherapy is to optimize the irradiation of the target volume and to optimize the irradiation of the target volume and to reduce the dose to critical organs. The use of imaging (computed tomography and magnetic resonance imaging (computed tomography and magnetic resonance imaging added to clinical findings and standard guidelines) are studied in the treatment planning of external irradiation and brachytherapy in carcinoma of the cervix. Imaging allows an individualized and conformal treatment planning. (author)

Lynch syndrome, a hereditary cancer syndrome, occurs because of germline mutations in at least one of four DNA mismatch repair genes (MutL Homolog 1 ( MLH1 ), MutS Homolog 2 ( MSH2 ), MutS Homolog 6 ( MSH6 ), and PMS1 Homolog 2 ( PMS2 )). The disorder is associated with colorectal, endometrial, and other epithelial malignancies, but not cervical cancer. We report a woman with Lynch syndrome with synchronous cervical cancer. This is the first report of Lynch syndrome-related clear cell carcinoma of the cervix, which indicates the possibility of an association between cervical cancer and Lynch syndrome. Suitable genetic tests are required to determine whether common genetics can account for synchronous or subsequent malignancies in Lynch syndrome patients and their families. Such knowledge will also enhance our understanding of the genetic mechanisms governing the development of apparently unrelated cancers.

Stage 2 carcinoma of the cervix

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.

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

We studied on scintigraphy for demonstration of primary site and infiltrating area of carcinoma of uterine cervix by using 111 In-BLM, which is drawing attention as one of the tumor-imaging agents. In 17 cases (77%) out of 22 cases of the carcinoma of uterine cervix, this scintigraphy demonstrated the primary site and the extent of infiltration into parametrium with distinctive positive images. Thus, this radiopharmaceutical was found to be of great use for determining the treatment of the carcinoma of uterine cervix. (author)

Role of surgery in breast metastasis from carcinoma of the cervix

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.

Using integrated PET/CT, we evaluated the prognostic value of [ 18 F]FDG uptake ratio between pelvic lymph node (LN) and primary tumor in invasive squamous cell carcinoma (SCCA) of the uterine cervix. We retrospectively reviewed patients with International Federation of Gynecology and Obstetrics (FIGO) stages IB to IIA cervical SCCA who underwent preoperative [ 18 F]FDG PET/CT scans. PET/CT parameters such as maximum standardized uptake value (SUV) of the primary cervical cancer (SUV cervix ) and LN (SUV LN ), and the LN-to-cervical cancer SUV ratio (SUV LN /SUV cervix ) were assessed. Prognostic values of PET/CT-derived metabolic and volumetric variables and clinicopathology parameters were analyzed to predict progression-free survival (PFS) in regression analyses. Clinical data, treatment modalities, and results were reviewed for 103 eligible patients. Median post-surgical follow-up was 29 months (range, 6-89), and 19 (18.5%) patients experienced recurrence. Multivariate logistic regression analysis showed that SUV LN / SUV cervix > 0.1747(P = 0.048) was the independent risk factor of recurrence. Patient group categorized by SUV LN /SUV cervix showed significant difference in PFS (log-rank test, P < 0.001). Preoperative SUV LN /SUV cervix measured by [ 18 F]FDG PET/CT was significantly associated with recurrence, and has an incremental prognostic value for PFS in patients with cervical SCCA. (orig.)

Value and importance of intracavitary therapy in uterine cervix carcinoma

Frischkorn, R.

1986-01-01

The guiding topic of this report was 'the value and importance of intracavitary therapy in uterine cervix carcinoma'. This implies first of all the task to assess the importance of contact therapy within the scope of all therapeutic measures taken in case of uterine cervix carcinoma. Furthermore it was necessary to compare the importance of the different methods of contact therapy: conventional radium therapy as well as low dose rate and high dose rate afterloading techniques. As to surgical intervention, it is clear that only favorable stages can be taken into consideration for this treatment. It is shown by means of data taken from the Annual Report, Vol. 18, that a considerable number of patients with uterine cervix carcinoma I are irradiated even in hospitals whose field of activity lies preponderantly in surgery, and that by far most of the patients cured from uterine cervix cancer owe their recovery to contact therapy. The consideration of contact therapy methods show clearly that radium should no longer be used in clinical practice. Psychological doubts often hinder the decision if long-term or short-term afterloading therapy is to be applied. It is therefore shown that the very different forms of radium therapy with their chronological and spatial dose distribution were due to the characteristics of radium (e.g. little specific activity) or to other compelling features and that they were not based on radiobiological aspects. The radium dose values obtained by empirical research and the resulting spatial and chronological dose distribution are therefore not imperative. So it is not inevitable to choose the low dose rate afterloading method. On the contrary, the high dose rate technique with an adequate fractionation is very probably the method of choice. To sum up it can be said that contact therapy is still the most important therapeutic method in uterine cervix cancer. (orig.) [de

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)

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.

Ninety-one patients with carcinoma of the cervix received radical radiation therapy from May 1981 through August 1983 at NIRS hospital. The correlation between eight CT findings and the prognosis was analysed in 75 patients, performed CT scan within 15 days form the admision. Among these CT findings, area of uterine cervix correlates well with recurrence, and enlargement of para-aortic lymph nodes showed the strong correlation between metastasis. We also analized these data by a multivariate analytical method (quantification method II). There exists a correlation between the prognosis and the score of quantification method II, and this score will be a good index of the prognosis of patients with carcinoma of the cervix. (author)

Using integrated PET/CT, we evaluated the prognostic value of [{sup 18}F]FDG uptake ratio between pelvic lymph node (LN) and primary tumor in invasive squamous cell carcinoma (SCCA) of the uterine cervix. We retrospectively reviewed patients with International Federation of Gynecology and Obstetrics (FIGO) stages IB to IIA cervical SCCA who underwent preoperative [{sup 18}F]FDG PET/CT scans. PET/CT parameters such as maximum standardized uptake value (SUV) of the primary cervical cancer (SUV{sub cervix}) and LN (SUV{sub LN}), and the LN-to-cervical cancer SUV ratio (SUV{sub LN}/SUV{sub cervix}) were assessed. Prognostic values of PET/CT-derived metabolic and volumetric variables and clinicopathology parameters were analyzed to predict progression-free survival (PFS) in regression analyses. Clinical data, treatment modalities, and results were reviewed for 103 eligible patients. Median post-surgical follow-up was 29 months (range, 6-89), and 19 (18.5%) patients experienced recurrence. Multivariate logistic regression analysis showed that SUV{sub LN} / SUV{sub cervix} > 0.1747(P = 0.048) was the independent risk factor of recurrence. Patient group categorized by SUV{sub LN}/SUV{sub cervix} showed significant difference in PFS (log-rank test, P < 0.001). Preoperative SUV{sub LN}/SUV{sub cervix} measured by [{sup 18}F]FDG PET/CT was significantly associated with recurrence, and has an incremental prognostic value for PFS in patients with cervical SCCA.

Brady, L.W.

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

Indium-111 attached to bleomycin is useful in the scintigraphic localization of a variety of tumors. Since it does not normally accumulate in bowel and feces, it is superior to other radiopharmaceuticals, such as gallium-67-citrate, in the demonstration of abnormalities in the abdomen and pelvis. Twenty-eight patients with known carcinoma of the cervix were studied with whole body 111 In-bleomycin scans. Two ''false-positive'' scans were produced by local inflammation. Six ''false-negative'' scans were attributed to small tumors escaping scintigraphic detection. In the remaining 20 patients, scan findings correlated well with site and extent of the tumor as determined by other means. 111 In-bleomycin scintiscanning may prove to be a highly useful adjunct in the evaluation of patients with carcinoma of the cervix

1985-01-01

Between April 1968 and December 1980, 61 patients with phase III cancer of the cervix were treated. Fifty-six of them were squamous-cell carcinomas and five adenocarcinomas. The treatment consisted of a combination of external irradiation at doses varying between 4,000 and 7,000 rads and intracavitary radiotherapy with doses of 4.000 to 6.000 MHz, according to the schemes of the D.M. Anderson of Houston. The results obtained as far as survival is concerned and calculated by the actuarial method were 40% after five and ten years. The local control rate reached was 74%. The severe complications caused by the treatment reached 8.1%.

The measuremet of the serum level of squamous cell carcinoma-related antigen (SCC) purified from liver metastasis of cancer of the uterine cervix by an RIA kit is basically evaluated. The results of sensitivity, the recovery test, dilution test and variance test are good enough for clinical application. In gynecological disorders, the possitive rate is high (62 % [29/47]) in patients with cancer of the uterine cervix. Furthermore, the rate and level are related with the clinical staging. The changes of the serum SCC level in irradiated patients with cancer of the uterine cervix were a good reflection of the effectiveness of the treatment. (author)

1993-01-01

The aim of this study was to evaluate brachytherapy as the only treatment modality in inoperable early cervix carcinoma patients (carcinoma in situ, IA and IBocc). In a retrospective analysis 36 patients were treated with intracavitary irradiation between 1984 and 1988 in the Radiotherapy Department of the National Institute of Neoplasmic Diseases. Distribution by stage was; carcinoma in situ: one patient (2,47%), IA: six patients (16,6%), IBooc: twenty-nine patients (80,7%). Histology revealed epidermoid carcinoma in all cases. Mean age 55 years (range: 32-78). Treatment consisted in: two intracavitary applications of Radium, for 120 hours each, with a month interval, in 30 patients (carcinoma in situ: one, IA: four, IBocc: twenty-five patients), two applications of 72 hours each, with 15 days interval in four patients (IA: one, IBocc: 3) and one single intracavitary radium application in two patients (IA and IBocc). Local control was complete in all carcinoma in situ and IA patients. Only 1 of 29 patients with IBocc stage failed to respond, in spite of having received two applications, this shows that local response is independent of the number of insertions. Incidence of complications was low, and resolved with medical treatment. One patient had rectal adenocarcinoma 3 years after treatment -it was considered as radio induced neoplasm, since time of appearance was more than two years and localization was within irradiated area. Two patients died form intercurrent diseases, one (IBocc) from persistent diseases. Two patients were lost to follow-up. Three years survival was: 100% for carcinoma in situ and IA 86,2% for IBocc. Five years survival was 80% for IA and IBocc. Brachytherapy as unique modality of treatment is highly effective in initial cervix carcinoma stages. (author). 41 refs., 14 tabs., 2 figs., 1 ill

This study reports on 5 years experience of the treatment of carcinoma of the cervix and poor-risk carcinoma of the body of the uterus using a combination of external beam radiotherapy and high-dose-rate intracavitary 60Co-brachytherapy using the Cathetron since 1979 at the Middlesex Hospital, London. Despite a reduction in external beam dose of 20% since 1979, survival rates for both diseases remain unchanged and also compare favourably with those of other centres; they are 70.02% for carcinoma of the cervix of all stages except Ia, and 81.17% for 'poor-risk' carcinoma of body of uterus of all stages. The complication rates were acceptable. Analysis of the results of treatment by stage of disease in those patients with carcinoma of the cervix revealed that, except for Stage I cases, the results were comparable with those reported in the literature. The reason for the poor results in Stage I was found to be due to the high proportion of patients of 35 years of age and under with Stage I disease who fared significantly worse than older patients.

Hyperfractionated external radiation therapy in stage IIIB carcinoma of uterine cervix: a prospective pilot study

International Nuclear Information System (INIS)

Faria, Sergio L.; Ferrigno, Robson

1997-01-01

Purpose: Brazil has one of the highest incidence of carcinoma of the cervix in the world. Half of the patients have advanced stages at the diagnosis. Due to this large number of patients we decided to conduct a prospective pilot study to investigate the tolerance to and survival rate with hyperfractionated external radiotherapy only in patients with Stage IIIB carcinoma of the uterine cervix. Methods and Materials: Between January 1991 and December 1993, 23 patients underwent hyperfractionated external beam radiotherapy without brachytherapy. All cases were biopsy proven squamous cell carcinoma of cervix clinically Staged as IIIB (FIGO). Hyperfractionation (HFX) was given with 1.2 Gy doses, twice daily at 6-h interval, 5 days/week, to the whole pelvis up to 72 Gy within 30 working days. Complications were evaluated by an adaptation of the RTOG Radiation Morbidity Scoring Table graded as 1 = none/mild; 2 = moderate, and 3 = severe. Results: Follow-up ranged from 27 to 50 months (median 40 months) on the 9 to 23 living patients at the time of the analysis in December 1995. There was no severe acute toxicity, but moderate acute reaction was high: 74%. The commonest site of complication was the intestine where severe late toxicity occurred in 2 of 23 (9%). Overall survival rate at 27 months was 48% and at 40 months was 43%. Discussion: There is little information in literature about HFX in carcinoma of the cervix. This is the third published study about it and the one that gave the highest total dose with external HFX of 60 x 1.2 Gy = 72 Gy. Theoretically, through the linear quadratic formula this schedule of HFX would be equivalent to 30 x 2 Gy = 60 Gy of standard fractionation, both treatments given in 30 working days. HFX schedules must be tested to establish their safety. Present results suggest being possible to further increase the total dose in the pelvis with hyperfractionated irradiation

Mayr, B.; Schmidt, H.; Baieri, P.; Scheidel, P.; Meier, W.; Schramm, T.

1986-01-01

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

Neumann, U.; Klengel, S.; Kaulen, F.; Schorcht, J.

1997-01-01

There is an increasing interest in non-invasive measurement of hemodynamic parameters in tumors. MRI is a valuable method for the evaluation and morphological staging of cervix carcinomas. The sensitivity to radiation should correlate with the pathoanatomical grade of vascularization. We tested the value of perfusion imaging in cervix tumors before and after radiation to optimize therapy. In 38 patients with cervix carcinoma (stage T2-T4) we simultaneously measured dynamic T 1 and T 2 * signal changes after bolus application of the paramagnetic contrast medium Gd-DTPA. We detected 3 patterns of uncorrected simultaneous dynamic T 1 and T 2 * signal changes in cervix tumors, which allows the differentiation of high, reduced and no T 2 * signal loss. Most tumors with a strong perfusion effect showed good regression during and after radiation therapy. More than 60% of cervix carcinomas with low or no perfusion effects were characterized by incomplete tumor reduction. Further study is necessary to prove the statistical significance allowing prospective differentiation of cervix tumors into therapy-responders and non-responders. (orig.)

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

Two hundred and eighteen patients were referred to the Oxford Radiotherapy Department in the 5 years 1973-77 with stages I and II tumours of the uterine cervix. One hundred and eighty-one underwent pre-operative intracavitary radiotherapy followed by Wertheim hysterectomy and pelvic lymphadenectomy. Twenty-three per cent of these patients had metastatic disease in pelvic lymph nodes. Fifty-five per cent of patients with positive pelvic nodes died of carcinoma of the cervix compared with 9% of negative node cases. Prognostic factors are discussed and management of carcinoma of the cervix reviewed. (author)

Consecutive 50 cases of squamous cell carcinomas of the uterine cervix diagnosed in 1992 were subjected to immunohistochemical study for ras oncogene product (p21) and MHC class II (DR) antigen using a microprobe immunostainer. Activated ras and aberrant DR expression were noted in 26 cases (52%) and 11 cases (22%) of cervical squamous cell carcinomas, respectively, without difference among histologic types. The reaction was mainly intracytoplasmic, with granular staining pattern and diffuse distribution. No direct histologic correlation between ras and DR expression was found. Four cases with HPV 16/18 DNA in superficial koilocytotic cells, revealed by in situ hybridization, showed various expression of ras and DR, and these 3 factors histologically did not seem to be affected one another.

Analytic study of regional changes in carcinoma of the cervix uteri following linac irradiation, 3

International Nuclear Information System (INIS)

Yamashita, Michitaka

1977-01-01

To observe regional changes following Linac irradiation therapy for 15 patients with carcinoma of the cervix uteri, an electron microscopic study of the carcinomatous cells of a parabasal type was made, and the following conclusion was obtained. Early changes which were seen following 1000 R irradiation were an appearance of various lysosomes and a remarkable appearance of the Golgi's apparatus. Some other changes were noted in mitochondria, vesicles, and free ribosomes, while very slight changes in the nuclei. After 2000 R irradiation, the foregoing early changes and a tendency of cells separated became more distinctive. Following an irradiation of 3000 R, changes were noted in the nuclei, destruction of the nuclear membrane and agglutination of chromatin being prominent. Glycogen granules were also noted. After an irradiation of 4000-5000 R, the carcinomatous cells were necrotized and ill-defined. There were remarkable destructions of the nuclei and intracellular organellas. On the basis of the foregoing findings, it is considered that the effect of irradiation on the carcinomatous cells of a parabasal type in carcinoma of the cervix uteri appears as a change in the cytoplasm which is followed by the destructive change of the nuclei. A difference in the effect of irradiation was conspicuous in the changes of the lysosome. In remarkably effective cases, there occurred an early appearance and an early inactivation of the lysosome. However, in ineffective cases, those changes appeared after receiving 1000 R more irradiation. (Ueda, J.)

Long term follow up results of serum squamous cell carcinoma antigen level in uterine cervix cancer treated by radiotherapy

International Nuclear Information System (INIS)

Yun, Hyong Geun

2003-01-01

To evaluate the long term significance of the squamous cell carcinoma (SCC) antigen (Ag) as a tumor marker in uterine cervix carcinoma. The SCC antigen levels of pre-radiotherapy and serial post-radiotherapy serum were analyzed in 48 patients who received radiotherapy with histologically proven primary SCC of the uterine cervix. Pre-radiotherapy SCC Ag level was high (≥2 ng/ml) at 79.2%. After the treatment, the SCC Ag level was significantly decreased. The SCC Ag level measured at about 3 months after radiotherapy was high at 23.0%. In further follow up measurements, a rise of the SCC Ag to a high level was well associated with clinical relapse. The specificity of the elevated SCC Ag level in association with recurrent or persistent disease was 100%, and the sensitivity was 85.7%. In 3 of 4 lung metastasis cases, lung lesions were detected in chest PA before elevation of the SCC Ag level. The median lead time of the high SCC Ag level to clinical recurrence was 4 months. SCC Ag was a good tumor marker for monitoring treatment effect in patients with increased pre-treatment levels except in case of early lung metastasis. Elevation of the SCC Ag level after radiotherapy accurately predicted the treatment failure with lead time of 4 months. But, in early lung metastasis cases, the SCC level may be normal temporarily. Thus, chest PA should be checked to evaluate the presence of lung metastasis

Clinical significance of shape of isodosecurves in intracavitary radiation therapy in carcinoma of the uterine cervix

Higuchi, Tatsuo

1985-01-01

In intracavitary radiation therapy of carcinoma of the uterine cervix, deviated position of microsources in the uterine and vaginal cavities from standard position was classified as follows: (1) Slipped position of a whole system of microsources. (2) Slipped position of the uterine tandem. (3) Slipped position of the colpostat. (4) Anteversion-flexion position of the uterine tandem. (a) Anterior displacement of the vaginal colpostat. (b) Posterior displacement of the vaginal colpostat. (5) Retroversion-flexion position of the uterine tandem. (a) Posterior displacement of the vaginal colpostat. (b) Retroposed position of the uterine tandem. (6) Side inclination of the uterine tandem. In every position, dose distribution around microsources was calculated by computers and isodosecurves in the vicinity of the cervix were constructed in three dimensions. Advantage and disadvantage of shape of these isodosecurves were discussed clinically with special reference to dosage of the lesions, rectum and bladder which was delivered from microsources. Besides these studies we clarified the reason why adequate cancerocidal dosage of carcinoma of the uterine cervix in the aged was much less than in the younger on the basis of anatomical and tumor size difference between two groups. The similar difference could be found between Japanese and Westerns in radiation therapy of carcinoma of the uterine cervix. (author)

Purpose: To study the prognostic value of human papillomavirus (HPV) genotypes in patients with advanced cervical cancer treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). Methods and Materials: Between August 1993 and May 2000, 327 patients with advanced squamous cell carcinoma of the cervix (International Federation of Gynecology and Obstetrics stage III/IVA or stage IIB with positive lymph nodes) were eligible for this study. HPV genotypes were determined using the Easychip® HPV genechip. Outcomes were analyzed using Kaplan-Meier survival analysis and the Cox proportional hazards model. Results: We detected 22 HPV genotypes in 323 (98.8%) patients. The leading 4 types were HPV16, 58, 18, and 33. The 5-year overall and disease-specific survival estimates for the entire cohort were 41.9% and 51.4%, respectively. CCRT improved the 5-year disease-specific survival by an absolute 9.8%, but this was not statistically significant (P=.089). There was a significant improvement in disease-specific survival in the CCRT group for HPV18-positive (60.9% vs 30.4%, P=.019) and HPV58-positive (69.3% vs 48.9%, P=.026) patients compared with the RT alone group. In contrast, the differences in survival with CCRT compared with RT alone in the HPV16-positive and HPV-33 positive subgroups were not statistically significant (P=.86 and P=.53, respectively). An improved disease-specific survival was observed for CCRT treated patients infected with both HPV16 and HPV18, but these differenced also were not statistically significant. Conclusions: The HPV genotype may be a useful predictive factor for the effect of CCRT in patients with advanced squamous cell carcinoma of the cervix. Verifying these results in prospective trials could have an impact on tailoring future treatment based on HPV genotype.

Bone injury after radiotherapy for carcinoma of the uterine cervix has been reported since early days of this century. Recently, the concept of insufficiency fracture has been confirmed. Insufficiency fracture is one of the stress fractures and occurs when the elastic resistance of bone is inadequate to withstand normal or physiological stress. In the American and European studies, radiotherapy is known as a cause of insufficiency fracture. There are no reports on insufficiency fracture in the Japanese literatures. Four cases of carcinomas of the uterine cervix presented pelvic insufficiency fractures following radiotherapy. In the pubic bone, a vertical parasymphyseal fracture with mixed lytic and sclerotic changes of surrounding tissue is characteristic. Sacral insufficiency fracture shows a vertical or horizontal line with lytic and sclerotic appearance. Bone scintigraphy is a sensitive modality for the early detection. H-shaped configuration is diagnostic for sacral insufficiency fracture. CT is an accurate technique demonstrating a vertical fracture and excluding the malignant bony lesion. Although radiological findings of insufficiency fracture are similar to bone malignancy, differential diagnosis from malignant lesions is possible. Bony symptoms of all patients disappeared without specific treatments. In the follow-up study of patients with carcinomas of the uterine cervix after radiotherapy, it is important to have the consideration on insufficiency fracture. (author)

Stage III carcinoma of the uterine cervix is occasionally accompanied by tumor infiltration of the vaginal wall. Currently, the vaginal wall has to be irradiated in the same manner as the uterine cervix. The authors have developed a system for determining the optimal irradiation conditions for treating the two regions, uterine cervix and vaginal wall, at the same time. A comparison of two methods is shown in simulation, and then a clinical case is reported. The first method consists of two treatment plans, one for the uterine cervix without tumor infiltration of the vaginal wall, and the other for the vaginal wall without carcinoma of the uterine cervix. The second, newly developed method considers the two regions together. Irradiation times of ovoid sources obtained with the second method are 15-25% less than those of the first method. Isodose curves obtained with the two methods are very different and thus the uterine cervix and vaginal wall must be considered together in order to determine irradiation conditions. (author)

Objective: to compare survival and toxicity of three different treatments for stage IIIB cervix cancer: low-dose-rate (LDR), high-dose-rate (HDR) brachytherapy and association of HDR and chemotherapy. Methods: between 1985 and 2005, 230 patients with FIGO stage IIIB squamous cell carcinoma of the uterine cervix received 4-field pelvic teletherapy at doses between 40 and 50.4 Gy, with a different complementation in each group. The LDRB group, with 42 patients, received one or two insertions of LDR, with Cesium-137, in a total dose of 80 to 100Gy at point A. The HDR group, 155 patients received HDR in 4 weekly 7 Gy fractions and 9 Gy to 14.4 Gy applied to the involved parametria. The CHT group, 33 patients, were given the same treatment as the HDR group and received 5 or 6 weekly cycles of cisplatin, 40 mg per m2. Results: the five-year progression-free survival (PFS) was 60% for the HDR group and 45% for the LDR group, and the two-year PFS for the CHT group was 65% (p = 0.02). The five-year Overall Survival (OS) was 65% for the HDR group and 49% for the LDR group. The two-year OS was 86% for the CHT group (p 0.02). Rectum toxicity grade II was 7% for the LDR group, 4% for the HDR group and 7% for the CHT group that had one case of rectum toxicity grade IV. Conclusion: patients that received HDR had better OS and PFS. The Chemotherapy-HDR association showed no benefit when compared to HDR only. Toxicity rates showed no difference between the three groups. (author)

To assess the effects of radiotherapy on immune status, a wide range of assessments have been performed on patients with localized carcinoma of the cervix uteri undergoing and initially responding clinically to radical pelvic radiotherapy. neutrophil function was essentially unchanged by treatment. Absolute neutrophil and lymphocyte counts fell after treatment and remained depressed 3 and 12 months following treatment. The proportions of T and B cells dropped with treatment but recovered to near-presentation levels during the follow-up period even though absolute counts remained depressed. In vitro tests of cellular immunity were depressed by treatment and remained so 3 and 12 months following treatment whereas skin test responses remained normal throughout the assessments. Inhibitory plasma effects were observed in photohaemagglutinin lymphocyte transformation studies on 4 untreated patients; at follow-up these effects were not evident. A variable response in immune indices has therefore been observed in patients in remission after treatment of localized carcinoma cervix stressing the importance of assessing several aspects of immune function and implying that persistent depression of certain indices does not adversely affect the host tumor response. In two patients relapsing after apparently good initial response, all aspects of immunological assessment (except serum immunoglobulin levels and neutrophil function) deteriorated

The relationship among the incidence, the time of occurrence, and radiation dose was studied in regard to hemorrhagic cystitis after radiotherapy for carcinoma of the cervix uteri. Of 1004 patients with carcinoma of the cervix uteri observed between 1961 and 1974, 28 (2.8%) had bladder hemorrhage seemingly due to radiation injury (0.7% were serious). Incidences varied every year. The radiation dose was increased from 4000 to 6000 rad after 1971. In addition to this external dose, because the depth-dose has also increased, the rate of bladder hemorrhage has become high. Seven patients with serious bladder hemorrhage were exposed to more than 5000 rad of 60 Co. Bladder hemorrhage occurred comparatively frequently in patients in whom two hila were irradiated. It usually occurred a few years after irradiation (about 1 year after initial rectal hemorrhage). It continued for approximately 1 year in 21 patients, for approximately 3 years in 4 patients, and for approximately 4 years in 3 patients. Adrenochrome (a hemostatic agent) and antiplasmin were used as therapeutic agents. Serious patients improved remarkably when a large amount of diluted formaline solution or conjugated estrogen was administered intravenously. (Namekawa, K.)

From 1964 to 1980, 97 patients with Stage IIb carcinoma of cervix uteri were treated by external 60Co irradiation alone. Of these 97 patients, 94 (96.9%) had squamous cell carcinoma. The parametrial extension of the lesion almost reached the pelvic wall in 73.2% and vaginal extension reached to the upper half of vaginal in 24.7% of the patients. A tumor dose of 60 Gy was given to the whole pelvis by a four field technic (opposing parallel AP and lateral portals) in 6-8 weeks. A booster dose of 10 Gy was delivered to the cervix by a pair of reduced opposing parallel AP portals or a perineal portal in a week. The doses delivered were equivalent to the Time-Dose-Fractionation (TDF) value of 110-130 at the center of pelvis and 90-110 in the whole pelvis. The 5-year survival rate for all 97 patients was 56.7%. It was 59.8% when those who died of other diseases were excluded. The prognosis of patients without residual tumor on the cervix and/or vagina was better than that with residual tumor (p less than 0.01). Thirty-seven patients died of cancer (23 died of recurrence, 8 of distant metastases, 2 of both, and 4 were lost before the fifth year). Of these 37 patients, 97.3% died within 3 years after initial treatment. During the radiation treatment, reactions were moderate. Late complications included 19 (19.6%) with mild cystitis and 16 (16.5%) with mild proctitis, 2 (2.7%) developed recto-vaginal fistula. These results were slightly poorer than those using intracavitary and external irradiation or the combination of preoperative irradiation plus surgery. Yet, for patients with extensions nearing the pelvic wall or with contra-indications to surgery or intracavitary radiotherapy, external irradiation alone is still of value

The protocol used allows an excellent local control of the uterine cervix carcinoma with an acceptable morbidity. To anticipate the presence of a tumor residue can be an evolution in the therapy management after external radiotherapy, particularly in optimized image-guided brachytherapy (MRI and PET)New utero vaginal applicators with parameters implantation allow to realise the dose complement at the distal parameters. These advances make consider an improvement of results in the management of locally evolved uterine cervix carcinomas. (N.C.)

Grading of malignancy in squamous cell carcinomas of the uterine cervix is based on qualitative, morphologic examination and suffers from poor reproducibility. Using modern stereology, unbiased estimates of the three-dimensional, volume-weighted mean nuclear volume (nuclear vv), were obtained...... in pretreatment biopsies from 51 patients treated for cervical cancer in clinical Stages I through III (mean age of 56 years, follow-up period greater than 5 years). In addition, conventional, two-dimensional morphometric estimates of nuclear and mitotic features were obtained. DNA indices (DI) were estimated...

The therapeutic effects of radiotherapy of carcinoma of corpus uteri and cervix in the years 1967-1972

International Nuclear Information System (INIS)

Lembong, J.T.

1980-01-01

The results of radiotherapy of 374 cases of cancer of the cervix uteri, 163 cases of carcinoma of the endometrium, 24 cases of cancer of the cervival stump and 16 cases of sarkoma of the uterus carried out during the years 1967 to 1972 are shown. The absolute 5-year cure rates in our case material were 60,4 % for cancer of the cervix uteri and 73,0 % for carcinoma of the endometrium. In comparison with the treatment results reported in the years 1962 to 1966 an increase in radiotherapeutical efficiency was found, amounting to 8,8 % in case of cancer of the cervix uteri and 13,2 % in case of carcinoma of the endometrium. We also compared and analysed the different cure rates in case of primary irradiation (52,6 % resp. 55,8 %) as opposed to postoperative radiotherapy '76,9 % resp. 81,1 % cure rates). The frequency of radiation injuries and the rate of recurrence or metastases, as well as the incidence of concomitant diseases and complications have been reported and compared with those of other clinics.

One of the most important prognostic features of early cervix cancer is the involvement of regional lymph nodes (LN). Although not fully studied, the sentinel node (SN) strategy has the potential of preventing unnecessary extensive LN dissections in these patients. The aim of this study was to determine the feasibility of SN identification by means of preoperative lymphoscintigraphy (PL) and intraoperative gamma probe detection (IGPD) in patients undergoing radical hysterectomy and pelvic/para-aortic lymphadenectomy for the treatment of early cervix carcinoma.

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.)

Small cell carcinoma of the gynecologic tract: a multifaceted spectrum of lesions.

Small cell carcinoma (SmCC) of the female genital tract constitutes a diagnostic and clinical challenge given its rarity and the lack of standardized therapeutic approaches. Here we review the morphological, clinical and molecular features of gynecologic SmCCs and discuss potential areas for future research. Data for this review article were identified by searches of PubMed, EMBASE and the Internet using the search terms "small cell carcinoma" or "neuroendocrine carcinoma" and "gynecologic", "uterine cervix", "cervix", "uterus", "endometrium", "ovary", "vagina", "fallopian tube" or "vulva", and research articles published in English between 1972 and February 2014 were included. SmCCs arising from different organs within the gynecologic tract share the same histopathologic characteristics, which closely resemble those of small cell lung carcinoma. The expression of at least one immunohistochemical neuroendocrine marker is a common finding. The uterine cervix is the most frequent site of SmCC in the female genital tract. HPV infection seems to play a role in the development of cervical SmCC but not in cancers of other gynecologic sites. FIGO stage is an established prognostic factor, in particular in SCCs of the cervix. Irrespective of the site, SmCCs of the gynecologic tract display an aggressive clinical behavior with few reported long-term survivors. The therapeutic management includes surgery, radiotherapy and chemotherapy. Despite the potential differences in etiology and risk factors, SmCCs from different sites of the gynecologic tract have similar morphologic appearances and clinical behavior. Recent genomic analyses of small cell carcinoma of the lung have revealed potential driver genomic alterations. We posit that the comprehensive genomic characterization of gynecologic SmCCs may lead to the identification of markers that result in an improvement of diagnostic reproducibility of SmCCs of the gynecologic tract, and of molecular aberrations that may be

The long-term evolution of rectosigmoidal complications in carcinoma of the uterine cervix treated exclusively with irradiation

Pernot, M.; Bey, P.; Stines, J.; Hoffstetter, S.

1985-01-01

We made a retrospective analysis of 216 patients with carcinoma of the uterine cervix treated, from 1973 to 1978, with irradiation alone (177 patients with carcinoma of the cervix and 39 patients with carcinoma of the cervical stump). Of the 177 patients with carcinoma of the cervix, 25 patients were suffering from recto-sigmoidal complications, which in only 3% of them were considered serious. Of the 39 patients with carcinoma of the cervical stump, nine presented complications; in 5,1% the complications were regarded as serious. A good correlation existed between the degree of severity of the rectal symptoms and the Cumulative Maximal Rectal Dose (C.M.R.D.); on the other hand, a correlation could not be ascertained between the severity of the sigmoidal symptoms and the same C.M.R.D. Patients with severe sigmoidal complications, who had developed a stricture, had always received a dose higher than 80 Gy. The most serious rectosigmoidal complications occurred essentially in two situations: in patients in whom following the brachytherapy the central area had been inadequately shielded during the external irradiation. In patients who received a dose of external irradiation in excess of 50 Gy before brachytherapy. In order to prevent these complications, it is advisable to irradiate the pelvic area with doses of 40 to 45 Gy before brachytherapy, and to complete at once the irradiation of the node areas (with central shielding); the dose transmitted to the pelvic wall by brachytherapy must be calculated and included in the total dose administered. The 7 to 12 year follow-up after therapy showed that only 5 patients out of 216 developed severe complications. The crude survival rate of the 3 to 5 year follow-up of patients with carcinoma of the uterine cervix treated exclusively with irradiation between 1973 and 1978 was: T1 83,7 and 77,5%, T2 67,3 and 61,8 %, T3 42,2 and 31,3% [fr

Logsdon, Mark D.; Eifel, Patricia J.

1999-01-01

Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Methods and Materials: The records of 1,096 patients treated with radiation therapy between 1960 and 1993 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. Of these, 983 (90%) were treated with curative intent and 113 were treated only to achieve palliation of symptoms. Of 907 patients who completed the intended curative treatment, 641 (71%) were treated with a combination of external beam irradiation (EBRT) and intracavitary irradiation (ICRT) and 266 (29%) were treated with EBRT only. The median duration of treatment for these 907 patients was 51 days. Between 1966 and 1980, only 52% of patients who completed treatment with curative intent received ICRT, compared with 92% of patients treated during 1981-1993, an increase that reflects an evolution in the philosophy of treatment for advanced tumors. In general, the intensity of ICRT correlated inversely with the dose of EBRT to the central pelvis. Median follow-up of surviving patients was 134 months. Results: For 983 patients treated with initial curative intent, disease-specific survival (DSS) was significantly worse for those who were 52 Gy of EBRT to the central pelvis had DSS rates of 27-34%, compared with 53% for patients treated with lower doses of EBRT to the central pelvis and more intensive ICRT (p 52 Gy of EBRT to the central pelvis (57-68%), compared with those who had 48-52 Gy (28%) and those who had ≤ 47 Gy of EBRT to the central pelvis (15%) (p < 0.0001). Outcome was also compared for four time periods during which different treatment policies were in place for patients with Stage IIIB disease. The highest DSS (51%) and lowest actuarial complication rate (17%) were achieved during the most recent period (1981-1993) when modest doses of EBRT were combined with relatively

In patients with early cervix carcinoma, both radiotherapy and surgery or combined modalities provide effective therapies. In the two last modalities, recommended surgery is radical hysterectomy. The purpose of this prospective study was to assess the value of a limited vaginal hysterectomy after brachytherapy in patients without any unfavorable prognostic factor. Twenty-two patients (stage la2 with vascular invasion: three patients, stage lb1:19 patients) with 1 cm median maximal tumor size and with previous negative laparoscopic lymphadenectomy (median number of lymph nodes:12) underwent a limited vaginal hysterectomy 6 weeks after utero-vaginal brachytherapy. Two mild intra-operative complications were noted. Venous hemorrhage (100 mL) occurred in one patient during lymphadenectomy and another patient presented bladder injury during hysterectomy. These two complications were successfully controlled with no need for laparotomy. Only one late complication was observed: bladder grade G2(b). With a 29 months follow-up (20-48 months), no recurrence was reported. These results appear promising in patients with very early cervix carcinoma but remain to be confirmed on a larger scale.

The objective of this study was to examine a possible association of hemoglobin with clinical outcome in patients with locally advanced squamous cell carcinoma of the cervix who were treated with concurrent chemoradiotherapy (CCRT). Seventy-five patients with Stage IB to IVA disease who were treated with CCRT were reviewed retrospectively. The mean age was 49.8 years. In the treatment, standard radiotherapy was performed accompanied by concomitant chemotherapy using cisplatin. Pre-treatment hemoglobin was defined as the earliest hemoglobin level prior to the initiation of treatment. Weekly nadir hemoglobin levels throughout treatment were averaged and used as average weekly nadir hemoglobin during treatment (AWNHg). The mean follow-up time was 28.6 months. The mean pre-treatment hemoglobin of 11.6 g/dL was significantly reduced to the mean AWNHg of 9.9 g/dL. The levels of pre-treatment hemoglobin and AWNHg were significantly associated with tumor response to treatment. The 5-year cumulative disease-free survival and overall survival rates for all 75 patients were 67.8% and 75.3%, respectively. Multivariate statistical analysis revealed that AWNHg (≥9.0 versus <9.0 g/dL) was an independent prognostic factor for overall survival (p=0.038), but pre-treatment hemoglobin was not a significant factor. AWNHg was one of the most powerful independent predictors of overall survival in patients undergoing CCRT for locally advanced squamous cell carcinoma of the cervix. (author)

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.

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

Purpose: To report the long-term outcome after radiotherapy with curative intent for Stage IIIB and IVA carcinoma of the cervix. Methods and Materials: We retrospectively reviewed 91 patients treated with radiotherapy with curative intent at University of Florida between January 1980 and December 2003 for Stage IIIB (84 patients) or IVA (7 patients) carcinoma of the cervix. Results: The median follow-up of the surviving patients was 8.8 years. The 5- and 10-year estimates of local control, regional control, locoregional control, relapse-free survival, and overall survival were 53% and 53%, 55% and 47%, 34% and 29%, 30% and 26%, and 29% and 21%, respectively. Ninety percent of the recurrences occurred within 2 years of treatment. Of these, 60% of all failures were local, 29% were regional, and 11% were distant failures alone. Also, 17% of the failures were in the paraaortic nodes with no evidence of failure in the pelvis. Univariate and multivariate analyses were conducted with the endpoint of relapse-free or overall survival. No factor was statistically significant. Complications from therapy were scored using the Radiation Therapy Oncology Group grading system; the overall severe late complication rate was 13% (Grade 3-5). Conclusion: This series is one of the most mature of published reports. With long-term follow-up, approximately one-third of patients with Stage IIIB or IVA carcinoma of the cervix were cured, with a 13% complication rate

Relation between simple cytological test and persistence of disease in radiation-treated uterine cervix carcinomas

Energy Technology Data Exchange (ETDEWEB)

Schreiner, P

1985-07-01

A cytological study was conducted covering 174 epidermoid uterine cervix carcinoma patients who had been given combined radiation therapy. The changes were assessed in the karyopyknotic index (KPI) as related to radiation therapy and the incidence of local relapses. At the limit KPI value of 10, the average reliability of the method for diagnosing persistence in the group under study was 83.0%. Patients showing KPI of more than 10 at six weeks following the termination of radical radiation therapy represent a poor prognosis group whereas those showing KPI values lower than 10 have good prognosis. The results show that no strict hormonal dependence of the KPI value exists in uterine cervix carcinoma patients; only a different situation exists which is probably due to the tumor-organism interaction or to the metabolism of the tumor itself.

The early carcinoma of the uterine cervix may be treated by either radical surgery or radical radiotherapy according to the patient characteristics, and the survival is high with either treatment. But, because of the size of the lesion, metastasis to lymph nodes, and vascular space invasion by tumor have all been shown to influence recurrence and survival, postoperative radiotherapy may be considered as their histopathologic finding after radical surgery. However, there are still debates on the increasing survival rates with postoperative radiotherapy. Two hundreds and three patients with carcinoma of the uterine cervix who were treated with postoperative radiotherapy from February 1979 to September 1982 in the Department of Therapeutic Radiology, Seoul National University were analyzed and following results were obtained. 3-year actuarial survival rate and 3-year disease free survival rate were 83.4% and 73.4% respectively and 3-year actuarial survival rates by stages were 90.7% for I B, 69.6% for II A, and 85.2% for II b. The overall acute complication rate was 57.6%; tolerable cases was 50.2% and severe cases was 7.4%, Late complication rate was 7.9% and the major late complication were intestinal obstruction, aggravated urinary symptom, radiation cystitis in ORDER of frequency

Advantages of new flexible intracervical applicators treating cervical cancer with high dose rate afterloading brachytherapy are reported: The insertion of the flexible applicator is usually possible without anesthesia and dilatation of the cervix. Therefore the treatment can be performed on an outpatient basis. The risks of perforation and infection are minimal. Dosimetry and documentation of the applicator geometry are possible, if the planning system allows the definition of individual curves of an individual applicator. We now prefer flexible applicators instead of rigid steel applicators treating cervix carcinoma. (orig.) [de

Vascular complications after this treatment are rare. Artery stenosis or occlusions, more often iliac, are well recognized complications of postoperative radiotherapy. These segmental lesions, sometimes, are pathological lesions similar to arteriosclerotic changes. These lesions may be corrected later on after the treatment of carcinoma of the cervix. The venous complications often present later and tall within the context of post thrombotic syndrome. Conservative treatment is indicated alone. A well recognized complication, lymphedema is usually mild; a superimposed iliofemoral thrombophlebitis often may be suspected [fr

Following irradiation of a carcinoma of the cervix, the vagina is frequently narrowed or sometimes obliterated. This article considers the sexual functioning of women following such treatment. They noticed changes in their emotions and felt alterations in their function as a woman. They were less happy with cohabitation and found it more difficult to experience an orgasm. Their frequency of lovemaking diminished as did the occurrence of sexual dreams. A treatment scheme for helping such women with their sexual problems is outlined. (C.F.)

Carcinoma of the cervix is the commonest cancer seen in women at Sardar Patel Medical College, Bikaner (Rajasthan). In the present study external radio-therapy and brachytherapy are used in carcinoma cervix stage III B. After 4000 to 4500 rads to pelvis by external radio-therapy, patient was assessed for intra cavitary application. Total given dose to point A was 7500 rads, to point B was 5000 rads. If patient was not suitable a split course was given where patient was asked to come after 3 weeks for intracavitary application. A comparative study of both methods was done. There was significant improvement in the control of central disease by applying intracavitary source. Radiation reactions were comparable. (author). 4 tables, 10 refs

We have, studied the effect of radiation on humoral immunity in patients with carcinoma of the cervix by measuring variations in serum immunoglobulins (IgA, IgG, IgM) during radiotherapy. Of 81 patients with untreated cancer of the cervix (at stages Ib-IIIb), those at stage III had a significantly lower IgG level (P < 0.05) compared with control patients (94 in number). There was a significant fall (P < 0.05) in the mean serum IgA and IgG levels during radiation therapy in group A (36 patients who received this modality of treatment alone). However, in group B (26 patients who underwent pelvic lymphadenectomy prior to radiotherapy) and in group C (9 patients subjected to hysterectomy with pelvic lymphadenectomy before irradiation) there was no significant fall in the mean serum IgA and IgG levels. There were two distinct patterns of variation in serum immunoglobulins seen during external irradiation: type a) in which serum immunoglobulin levels tended to decline with the increase in radiation dose, and type b) in which serum immunoglobulin levels either remained the same as those prior to irradiation or varied in an irregular fashion during irradiation. There was a significant difference (P < 0.05) in the incidence of either type a) or b) for IgG and IgM between group A and groups B and C. The type a) pattern of serum immunoglobulin variation was more common in patients with stage 1 carcinoma, and was gradually superceded by type b) in more advanced cases. Thus it would appear that lymph nodes retain the ability to respond to radiation in most cases of early stage carcinoma, but lose this capacity with more advanced carcinoma, a finding which is suggestive of lowered ability for antibody production of the most bearing advanced carcinoma.

Full Text Available Abstract Background Abnormalities in the tumor microenvironment are associated with resistance to treatment, aggressive growth, and poor clinical outcome in patients with advanced cervical cancer. The potential of dynamic contrast-enhanced (DCE MRI to assess the microvascular density (MVD, interstitial fluid pressure (IFP, and hypoxic fraction of patient-derived cervical cancer xenografts was investigated in the present study. Methods Four patient-derived xenograft (PDX models of squamous cell carcinoma of the uterine cervix (BK-12, ED-15, HL-16, and LA-19 were subjected to Gd-DOTA-based DCE-MRI using a 7.05 T preclinical scanner. Parametric images of the volume transfer constant (K trans and the fractional distribution volume (v e of the contrast agent were produced by pharmacokinetic analyses utilizing the standard Tofts model. Whole tumor median values of the DCE-MRI parameters were compared with MVD and the fraction of hypoxic tumor tissue, as determined histologically, and IFP, as measured with a Millar catheter. Results Both on the PDX model level and the single tumor level, a significant inverse correlation was found between K trans and hypoxic fraction. The extent of hypoxia was also associated with the fraction of voxels with unphysiological v e values (v e > 1.0. None of the DCE-MRI parameters were related to MVD or IFP. Conclusions DCE-MRI may provide valuable information on the hypoxic fraction of squamous cell carcinoma of the uterine cervix, and thereby facilitate individualized patient management.

Purpose: To report the results of radiation therapy in carcinoma of the cervix treated by external irradiation and high-dose-rate (HDR) intracavitary brachytherapy. Methods and Materials: This is a retrospective analysis of 2063 patients with histologically proven carcinoma of the cervix treated by external irradiation and HDR intracavitary brachytherapy between March 1985-December 1991. The Kaplan-Meier method was used for survival and disease-free survival analysis. Late complications in the bowel and bladder were calculated actuarially. Results: There were 71 patients who did not complete the course of irradiation so only 1992 patients were retrospectively analyzed for survival. There were 2 patients (0.1%) in Stage IA, 211 (10.2%) Stage IB, 225 (10.9%) in Stage IIA, 902 (43.7%) in Stage IIB, 14 (0.7%) in Stage IIIA, 675 (32.7%) in Stage IIIB, 16 (0.8%) in Stage IVA, and 16 (0.8%) in Stage IVB. The median follow-up time was 96 months. The actuarial 5-year disease-free survival rate was 79.5%, 70.0%, 59.4%, 46.1%, 32.3%, 7.8%, and 23.1% for Stage IB, IIA, IIB, IIIA, IIIB, IVA, and IVB respectively. The actuarial 5-year disease-free survival rate for Stage IB 1 and IB 2 squamous cell carcinoma was 88.7% and 67.0%. The actuarial 5-year overall survival rate was 86.3%, 81.1%, 73.0%, 50.3%, 47.8%, 7.8%, and 30.8% for Stage IB, IIA, IIB, IIIA, IIIB, IVA, and IVB respectively. Pattern of failure revealed 20.8% local recurrence, 18.7% distant metastases, and 4% in both. The late complication rate Grade 3 and 4 (RTOG) for bowel and bladder combined was 7.0% with 1.9% Grade 4. Conclusion: HDR brachytherapy used in this series produced pelvic control and survival rates comparable to other LDR series

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.

Purpose: To define patient, tumor, and treatment factors that influence the outcome of patients with FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix. Materials and Methods: The hospital and radiotherapy records of 1007 consecutive patients treated between 1960 and 1989 for FIGO Stage IIIB squamous cell carcinoma of the intact uterine cervix were reviewed retrospectively. All patients were treated with radiation therapy (RT) either with curative intent (903 patients) or to palliate symptoms (104 patients). Patients who were selected for palliative treatment usually had a combination of adverse characteristics including massive tumor with bilateral pelvic wall fixation, hydronephrosis, bulky adenopathy, pathologic evidence of extrapelvic disease, and poor performance status. 64 (7%) of 903 patients failed to complete planned curative RT either because of progressive disease, complications, or poor compliance. Of 903 patients treated with curative intent, 319 (35%) were treated with external beam radiotherapy (EBRT) alone and 586 (65%) were treated with a combination of EBRT and intracavitary irradiation (ICRT). EBRT was usually delivered using 18-25 MV photons and ICRT was administered with Fletcher-Suit-Delclos applicators. Treatment philosophies evolved during the study period with greater emphasis placed on EBRT between 1966 and 1979 (52% treated with EBRT alone) compared with the other study years (15% treated with EBRT alone). 206 patients received investigational treatments including neutrons (69 pts), hyperbaric oxygen (66 pts), concurrent chemotherapy (29 pts), or neoadjuvant chemotherapy (42 pts). 875 patients have been followed until death. Median follow up for surviving patients is 171 months with only 9 surviving patients followed for 10%, or hgb < 10 gm% before treatment or at any time during radiotherapy. DSS was significantly better for patients whose treatment included ICRT (43% vs 21%; P< 0.0001). Also, patients who received

Full Text Available CONTEXT: Cancer of the uterine cervix is rare during adolescence. The reported rates are 0/100,000 adolescents aged 10 to 19 years and 1.7/100,000 women aged 20 to 24 years. However, several studies have shown increasing incidence of preneoplastic lesions at increasingly early ages. CASE REPORT: This paper reports a case of microinvasive carcinoma of the uterine cervix in a 14-year-old patient with menarche at 10 years of age and first coitus at 12 years of age. The objective of the present report was to alert gynecologists and pediatricians regarding the need for cervical carcinoma prevention among sexually active adolescents, based on educational programs that explain the purpose of colpocytological examinations and encourage their use, along with condom use and limitation of the number of sexual partners.

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.)

Between July 1979 and January, 1980, we treated 24 patients with carcinoma of the uterine cervix with RALS-TRON-20B, using the rapid processing system of pretreatment dose calculation. The incidence of rectal complications (3/24) was the same as that of a historical control group (5/28). According to ROC curve analysis, 5 rectal complications were related to the measured rectal dose, not to the point A dose or mg-hrs. Our findings suggest that hemorrhagic tendency, syphilis and diabetes mellitus influence the rectal complications. (author)

The study is concerned with immunologic status (cell-mediated and humoral immunity) as a factor influencing the choice of scheme of treatment for carcinoma of cervix uteri. The indexes of immunocompetence should be taken into account in planning the differential treatment of precancer and early forms of carcinoma of cervix uteri. Radiation treatment exerts an immunosuppressive effect. However, immunologic indexes are not affected considerably by laser destruction or surgery. Cryodestruction has a beneficial effect on cell-mediated immunity. Considering these effects as well as the long-term results of different orocedures of treatment, laser coagulation, cryogenic destruction or diathermoconization should be recommended for management of carcinoma in situ of cervix uteri, and extensive extirpation of the uterus, unattended by radiation, for Tla

To present the changes induced at the tissue level in patients subjected to external radiotherapy and brachytherapy to treat carcinomas of endometrium and cervix, as disclosed by magnetic resonance (MR). The MR study dealt with 26 patients 14 with endometrial carcinoma and 12 with cervical carcinoma who were treated with external radiotherapy and brachytherapy. The features assessed retrospectively were bone marrow of the lumbar and sacral spine, pelvic fat, abdominal wall, uterine, junction and size, rectal and bladder wall and pelvic musculature. The most common changes observed after radiotherapy according to our study were changes in signal intensity in the bone marrow of the pelvic bones (88%), followed by changes in the pelvic fat (65.3%). Other radiotherapy-related findings in order of frequency were cervical fibrosis, colitis and cystitis. Radiotherapy induces changes in the tissue of the pelvic structures, and the knowledge of these changes is important in the evaluation of the follow-up studies of these patients. (Author) 12 refs

Modification of radiation dose-rate sparing effects in a human carcinoma of the cervix cell line by inhibitors of DNA repair

The in vitro cell survival of a human cervix carcinoma cell line (HX156c) was assessed using /sup 60/Co ..gamma..-rays administered at 150 cGy/min or 3.2 cGy/min dose rate. Recovery during low dose-rate irradiation was observed; dose reduction factor at 10/sup -2/ cell kill for 150 versus 3.2 cGy/min was around 1.3. Possible underlying mechanisms of this recovery process have been investigated by addition of non-toxic concentrations of various agents thought to inhibit eukaryotic DNA repair. Differential effects among inhibitors were observed; aphidicolin had no effect on cell survival, novobiocin, hydroxyurea and 3-aminobenzamide reduced survival by a similar extent at both dose rates, ..beta..-ara A and caffeine reduced survival to a greater extent during low dose-rate irradiation. ..beta..-ara A and caffeine seemed to effect mainly by increasing the alpha component of the acute survival curve. Since survival curves obtained at dose rates of around 3 cGy/min help define a dominant component of the initial slope of the acute curve the authors claim to demonstrate that ..beta..-ara A and caffeine modify the initial slope, probably by inhibiting DNA repair processes involved in tumour cell sparing during protracted irradiation.

Ewing's sarcoma belongs to a spectrum of neoplastic diseases known as Ewing's family of tumors. This family of tumors is usually seen in osseous sites. Ewing's sarcoma of the cervix is extremely rare, with only 18 cases reported in the English literature. The immunohistochemical profile of Ewing's sarcoma overlaps with other malignancies like small cell carcinoma. The rarity and complex pathologic picture of Ewing's sarcoma of the cervix creates the potential for misdiagnosis. Hence, we believe this case needs to be reported to add to the available literature. A 49-year-old white Caucasian woman presented with vaginal bleeding. A pelvic examination revealed a cystic lesion arising from her cervix. Examination of a biopsy specimen revealed a poorly differentiated neoplasm, with sheets of small hyperchromatic cells, staining weakly for neuroendocrine markers. She was diagnosed with small cell carcinoma and started on concurrent chemotherapy and radiation. However, additional positive immunostaining for CD99 was strongly suggestive of Ewing's sarcoma. Fluorescence in situ hybridization revealed ESWR1 gene rearrangement, confirming Ewing's sarcoma. Our patient underwent surgery, which confirmed stage IIB Ewing's sarcoma. She received adjuvant chemotherapy but died from progressive metastatic disease after four cycles. With early diagnosis and appropriate treatment, Ewing's sarcoma of the cervix can be a potentially curable disease. However, owing to overlapping clinical and histopathological features, the diagnosis poses a challenge to oncologists and pathologists. This article guides pathologists to consider Ewing's sarcoma in the differential diagnosis of small cell carcinoma with weak staining for neuroendocrine markers. This literature review will benefit oncologists encountering this rare entity.

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.

The best way to treat locally recurrent carcinoma of the uterine cervix has not been established. This retrospective study refers to 37 consecutive patients, with recurrence in the pelvis, treated by radiotherapy alone. Thirty patients were treated by external beam therapy alone; intracavitary brachitherapy alone was adopted in 3 patients and a combination of both techniques in 4 patients. The total radiation dose exceeded 60 Gy in 62% of cases. A complete clinical response was observed in 54% of patiens and a partial response in 32.4%. Overall crude survival was 70.3%, 28.9% and 23.2% at 1, 3 and 5 years respectively. In patients with recurrent tumors less than 40 mm in diameter a threefold 3-year survival was achieved (48.6% vs. 14.5%, p<0.025). With total doses higher than 60 Gy the 3-year survival resulted to be far better than with lower doses (39.1% vs. 10%, p<0.025). A significant advantage was also observed in the ''complete responders'' group (44% vs. 11.8%), but this difference can be explained by the link between response and the above-mentioned basic prognostic factors. Acute side effects and late complications were moderate and did not correlate with the type of primary treatment. A significant percentage (about 25%) of patients with locally recurrent cervix carcinoma may reach medium-term survival; better results can be achieved in selected groups with favourable prognostsc factors and with adequate radiotherapic treatment

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.

Grading of malignancy in squamous cell carcinomas of the uterine cervix is based on qualitative, morphologic examination and suffers from poor reproducibility. Using modern stereology, unbiased estimates of the three-dimensional, volume-weighted mean nuclear volume (nuclear vv), were obtained...... in pretreatment biopsies from 51 patients treated for cervical cancer in clinical Stages I through III (mean age of 56 years, follow-up period greater than 5 years). In addition, conventional, two-dimensional morphometric estimates of nuclear and mitotic features were obtained. DNA indices (DI) were estimated...... of nuclear vv were only of marginal prognostic significance (2P = 0.07). However, Cox multivariate regression analysis showed independent prognostic value of patient age and nuclear vv along with clinical stage and DI. All other investigated variables were rejected from the model. A prognostic index...

NQO1 (NAD(P)H: quinone oxidoreductase-1), located on chromosome 16q22, functions primarily to protect normal cells from oxidant stress and electrophilic attack. Recent studies have revealed that NQO1 is expressed at a high level in most human solid tumors including those of the colon, breast, pancreas, ovaries and thyroid, and it has also been detected following the induction of cell cycle progression and proliferation of melanoma cells. In this study, we aimed to investigate the clinicopathological significance of upregulated NQO1 protein expression in squamous cell carcinomas (SCCs) of the uterine cervix. The localization of the NQO1 protein was determined in the SiHa cervical squamous cancer cell line using immunofluorescence (IF) staining, and immunohistochemical (IHC) staining performed on paraffin-embedded cervical SCC specimens from 177 patients. For comparison, 94 cervical intraepithelial neoplasia (CIN) and 25 normal cervical epithelia samples were also included. QRT-PCR was performed on RNA from fresh tissues to detect NQO1 mRNA expression levels, and HPV infection status was genotyped using oligonucleotide microarray. Disease-free survival (DFS) and 5-year overall survival (OS) rates for all cervical SCC patients were calculated using the Kaplan–Meier method, and univariate and multivariate analysis was performed using the Cox proportional hazards regression model. The NQO1 protein showed a mainly cytoplasmic staining pattern in cervical cancer cells, and only three cases of cervical SCC showed a nuclear staining pattern. The strongly positive rate of NQO1 protein expression was significantly higher in cervical SCCs and CINs than in normal cervical epithelia. High-level NQO1 expression was closely associated with poor differentiation, late-stage, lymph node metastasis and high-risk for HPV infection. Additionally, high-level NQO1 expression was associated with lower DFS and 5-year OS rates, particularly for patients with early-stage cervical SCCs

Objectives: To establish the cytological criteria to identify the urothelial cells in cervical smears in order to avoid mistakes in the cytological diagnosis. Materials and Methods: Cervical smears from 34 post menopausal women with vesicovaginal fistulas, advanced bladder prolapse and genital erosive lichen planes (vulvar kraurosis) (Group 1) and transitional cell metaplasia of the cervix (TCM, Group 2) were stained with Papanicolaou technique. The cervical samples were taken during the routine annual examination for prevention of the uterine cancer. Results: The smears of cervix from Group 1 showed urothelial cells from the three layers of the transitional epithelium. The umbrella cells are the bigger ones with relatively large nuclei. Frequently, they are multinucleated with single or multiple nucleoli and a typical “frothy” cytoplasm (cytoplasmic vacuoles). The cells of the Group 2 showed nuclei with oval to spindled shapes, some tapered ends, less cytoplasm than squamous metaplastic cells, powdery chromatin, small nucleoli and nuclear grooves. Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs) due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL) cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper. PMID:22438615

Neoadjuvant chemotherapy (NAC) and concurrent chemoradiotherapy (CCR) have been used to treat advanced squamous cell carcinoma of the uterine cervix. While the effectiveness of these therapies should be evaluated by a prospective randomized control study, no such study had ever been performed at the National Shikoku Cancer Center Hospital. For this reason, the authors assessed the results of radiotherapy after introduction of RALS (remote-controlled afterloading system) for patients with Stage IIIb squamous cell carcinoma of the uterine cervix and establish historical controls. The subjects were 95 patients (median age: 68 years) who had been treated at this hospital between 1983 and 1993. Twelve patients with PS4, severe complications, and active double cancer, received palliative external irradiation alone to the pelvis and 1 received palliative intracavitary received irradiation alone. The other 82 patients had external irradiation to the pelvis and intracavitary irradiation as curative irradiation. Thus, palliative irradiation and curative irradiation were performed in 13 cases and 82 cases, respectively. The overall survival rate (OAS), disease-specific survival rate (DDS), and disease-free survival rate (DFS) at 5 years in the palliative irradiation group were 7.7%, 16.8%, and 0%, respectively. In the curative irradiation group, OAS, DDS, and DFS were 56.1%, 65.9%, and 61.9%, respectively. Comparisons between the two groups showed significant differences each of the survival rates, and the outcome in the palliative irradiation group was very poor. Risk factors for recurrence were investigated, by comparing DFS among the 82 curatively irradiated cases, but no independent risk factors were identified by multivariate analysis.

The purpose of this study was to assess the accuracy of contrast-enhanced magnetic resonance imaging (dynamic MR imaging) in the evaluation of preinvasive and early invasive cancer of the cervix. Twenty-nine women with untreated squamous cell carcinoma of the cervix with either no stromal invasion or early stromal invasion underwent pretreatment MR imaging and dynamic MR imaging within 4 weeks of surgical evaluation. The images were evaluated for tumor detection and compared with results of histologic examination of the surgical specimens. The lesions in 17 cases with histologically proven stromal invasion of 4 mm or greater were detected with dynamic MR imaging, whereas lesions in only 8 of these cases were detected with T2 imaging. In 9 cases with stromal invasion between 4.0 mm and 5.0 mm, lesions were represented as early phase focal enhancement on dynamic MR images, but not detected on T2-weighted images. In the 12 cases with less than 4 mm stromal invasion, no lesions were visualized on either T2-weighted images or dynamic MR images, except in 1 case of glandular involvement without stromal invasion that appeared as enhancement on early-phase dynamic MR imaging. Dynamic MR imaging detected more lesions of early stromal invasion in pretreatment imaging for cervical cancer than nonenhanced MR imaging. (author)

Carcinoma cervix is the most common gynecological malignancy among Indian women. The common symptoms at presentation include abnormal vaginal bleeding, unusual discharge from the vagina, or pain during coitus and postmenopausal bleeding. Rarely, few patients may present with distant metastases without local symptoms. We present two patients with an unusual presentation of metastatic disease without any gynecological symptoms, where 18 F-flouro deoxy glucose positron emission tomography/computed tomography helped in identifying the primary malignancy in the uterine cervix

Podoplanin and SOX2 Expression in CIN 3-like Squamous Cell Carcinoma of the Cervix.

Squamous cell carcinoma (SCC) of the uterine cervix occasionally demonstrates a deceptive growth pattern that mimics endocervical crypt involvement by cervical intraepithelial neoplasia, grade 3 (CIN 3). Such CIN 3-like SCCs may be misinterpreted as noninvasive or minimally invasive leading to delays in diagnosis. Little is known of the factors that influence the growth patterns of cervical SCC but we suggested recently that CIN 3-like tumors might demonstrate "collective cellular invasion," which is characterized by a retained epithelial phenotype. This contrasts with the more overtly infiltrative growth of conventional SCC, which exhibits features suggestive of epithelial-mesenchymal transition. In the current study we investigated podoplanin (PP) and SOX2 expression in normal squamous epithelium, in CIN 3 and in 16 CIN 3-like SCCs 11 of which also showed a conventional invasive component. Compared with normal epithelium, CIN 3 often showed a focal loss of basal PP staining and most cases showed increased, typically diffuse, SOX2 expression. Although the immunohistochemical findings were not uniform, they generally supported collective cellular invasion in CIN 3-like tumor areas as these were often PP positive and showed diffuse SOX2 expression. In contrast, most conventional SCCs showed only focal SOX2 staining and they were typically negative, or only focally positive, for PP. The staining patterns did not reliably distinguish CIN 3 from CIN 3-like SCC. Small infiltrative tumor nests around the margins of CIN 3 or deeply invasive CIN 3-like SCC often showed a localized reduction in SOX2 expression suggesting SOX2 downregulation during the transition to invasive growth.

Cervical cancer is potentially the most preventable and treatable cancer. Despite the known efficacy of cervical screening, a significant number of women do not avail themselves of the procedure due to lack of awareness. This study was conducted to elicit information on the knowledge, attitude and practice (KAP) regarding screening (Pap test) and vaccination for carcinoma cervix among female doctors and nurses in a tertiary care hospital in Bangalore and to assess barriers to acceptance of the Pap test. A cross-sectional, descriptive study was conducted with semi-structured, self-administered questionnaire among female health professionals. The study subjects were interviewed for KAP regarding risk factors for cancer cervix, Pap test and HPV vaccination for protection against carcinoma cervix. Higher proportion of doctors 45 (78.9%) had very good knowledge as compared to only 13 (13.3%) of the nurses, about risk factors for cancer cervix and Pap test (p=0.001). As many as 138(89.6%) of the study subjects had favorable attitude towards Pap test and vaccination, but 114 (73.6%) of the study subjects never had a Pap test and the most common reason 35 (31%) for not practicing was absence of disease symptoms. In spite of good knowledge and attitudes towards cancer cervix and Pap test being good, practice remained low among the study subjects and most common reasons for not undergoing Pap test was absence of disease symptoms. The independent predictors of ever having a Pap test done was found to be the occupation and duration of married life above 9 yrs. Hence there is a strong need to improve uptake of Pap test by health professionals by demystifying the barriers.

Cervical carcinoma metastasizing to uveal tissue manifesting as pseudohypopyon

Full Text Available The metastasis to the eye in a patient of carcinoma of the cervix is rare. A case of carcinoma cervix in a 56-year-old female is described who presented with full chamber pseudohypopyon and deep vascularization in inferior quadrant of the cornea in the left eye. Magnetic resonance imaging revealed features suggestive of ocular metastasis in the anterior part of the uveal tract. Diagnosis was confirmed on cytology which showed features of squamous cell carcinoma. A high level of clinical suspicion in advanced cases of malignancies will help in early detection of ocular metastasis with unusual presentations.

The ''afterloading'' technique with use of Curietron (41 cases) or Selectron (43 cases) apparatus was applied in 83 cervix uteri carcinoma patients in phase 1b (79 cases) and 2a (4 cases). The Wertheim-Magis operation was performed after several weeks. Post-operative histologic investigation showed complete destruction of the tumour in 72% cases; persistent cancer cells in cervix uteri were stated in 11 patients (13%), while lymphatic node metastasis was seen in 14 patients (17%). Supplementary teleradiotherapy was performed in those cases. 39 patients (95%) of the 41 observed during 3 years survived without any cancer symptoms. No explicit relationship between dose administered to vaginal disc and cancer persistence frequency in the cervix uteri was stated. However, such relationship was stated for the dose in point A. In the group of 19 patients who received point A dose of the least 6000 rads, with average TDF value of 135, presence of cancer cells in cervix uteri was not stated in any of the cases. In 7 patients (17%) observed for over 3 years light and medium heavy postradiation complications were stated; in that 5 rectum side complications were stated in patients additionally irradiated from external fields, where the dose absorbed by rectum wall exceeded 8000 rads, with TDF - 150. No complications were observed when the dose was less than 5000 rads and TDF below 100. 16 refs., 1 fig. (author)

A project on the use of computerize planning and dosimetry for brachytherapy in carcinoma of cervix was started at NORI (Nuclear Medicine, Oncology and Radiotherapy Institute, Islamabad) in september 1990. A total number of 182 patients were included in the study over a period of three years. The treatment of all these patients was done by external radiation as well as the intracavitary therapy. Planning and dosimetry was done according to ICRU 38 recommendations. 70 patients were planned with two computers TP-II (Dr. J. Cunningham's software) and PC based system (Dr. Kallinger's software, BTI system). From the results of the two computers TP-II and PC, it can be seen that the difference in a absorbed dose for all recommended points in not going to harm the patient. The dose to the bladder and the rectum in our studies is quite low because of the low activity in the ovoid sources. (author)

While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

Psoas abscess is a rare clinical disease of various origins. Most common causes include hematogenous spread of bacteria from a different primary source, spondylodiscitis or perforated intestinal organs. But rarely some abscesses are related to malignant metastatic disease. In this case report we present the case of a patient with known squamous cell carcinoma of the cervix treated with radio-chemotherapy three years prior. She now presented with a psoas abscess and subsequent complete inferior vena cava thrombosis, as well as duodenal and vertebral infiltration. The abscess was drained over a prolonged period of time and later was found to be a complication caused by metastases of the cervical carcinoma. Due to the massive extent of the metastases a Whipple procedure was performed to successfully control the local progress of the metastasis. As psoas abscess is an unspecific disease which presents with non-specific symptoms adequate therapy may be delayed due to lack of early diagnostic results. This case report highlights the difficulties of managing a malignant abscess and demonstrates some diagnostic pitfalls that might be encountered. It stresses the necessity of adequate diagnostics to initiate successful therapy. Reports on psoas abscesses that are related to cervix carcinoma are scarce, probably due to the rarity of this event, and are limited to very few case reports. We are the first to report a case in which an extensive and complex abdominal procedure was needed for local control to improve quality of life.

Full Text Available A rare type of cervical cancer was encountered as a neuroendocrine cancer of cervix. Clinically, the patient presented with bleeding per vagina. She refused biopsy in her first visit and did not come for follow up. However, after few months she came and since there was a polypoid growth from cervix, she was advised to undergo hysterectomy. Histopathologically, it was diagnosed as large cell type of neuroendocrine cancer. Multimodality systemic treatment was offered as per literature. Ibrahim Med. Coll. J. 2009; 3(1: 36-38

Germline mutation in RNASEL predicts increased risk of head and neck, uterine cervix and breast cancer.

Directory of Open Access Journals (Sweden)

Bo Eskerod Madsen

Full Text Available UNLABELLED: THE BACKGROUND: Ribonuclease L (RNASEL, encoding the 2'-5'-oligoadenylate (2-5A-dependent RNase L, is a key enzyme in the interferon induced antiviral and anti-proliferate pathway. Mutations in RNASEL segregate with the disease in prostate cancer families and specific genotypes are associated with an increased risk of prostate cancer. Infection by human papillomavirus (HPV is the major risk factor for uterine cervix cancer and for a subset of head and neck squamous cell carcinomas (HNSCC. HPV, Epstein Barr virus (EBV and sequences from mouse mammary tumor virus (MMTV have been detected in breast tumors, and the presence of integrated SV40 T/t antigen in breast carcinomas correlates with an aggressive phenotype and poor prognosis. A genetic predisposition could explain why some viral infections persist and induce cancer, while others disappear spontaneously. This points at RNASEL as a strong susceptibility gene. METHODOLOGY/PRINCIPAL FINDINGS: To evaluate the implication of an abnormal activity of RNase L in the onset and development of viral induced cancers, the study was initiated by searching for germline mutations in patients diagnosed with uterine cervix cancer. The rationale behind is that close to 100% of the cervix cancer patients have a persistent HPV infection, and if a defective RNase L were responsible for the lack of ability to clear the HPV infection, we would expect to find a wide spectrum of mutations in these patients, leading to a decreased RNase L activity. The HPV genotype was established in tumor DNA from 42 patients diagnosed with carcinoma of the uterine cervix and somatic tissue from these patients was analyzed for mutations by direct sequencing of all coding and regulatory regions of RNASEL. Fifteen mutations, including still uncharacterized, were identified. The genotype frequencies of selected single nucleotide polymorphisms (SNPs established in the cervix cancer patients were compared between 382 patients

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.)

Purpose : Patients with cervical cancer who have positive resection margins after radical hysterectomy are at increased risk for local recurrence. The results of postoperative pelvic radiotherapy for cervix cancer with positive resection margins were analyzed to evaluated the role of radiotherapy. Materials and Methods : Between 1979 and 1992, 60 patients of cervix carcinoma were treated with postoperative radiotherapy after radical hysterectomy because of positive vaginal(48 patients) or parametrial resection margins(12 patients). Patients were treated with external beam radiation therapy(EBRT) alone (12 patients) or EBRT plus vaginal ovoid irradiation (VOI) (48 patients). The median follow-up period was 5 months. Results : The 5-year actuarial disease free and overall survival rates for all patients were 75.2%, 84.1%, respectively. The overall recurrence rate was 23%(14/60). In 48 patients with positive vaginal resection margins, the pelvic recurrence was 8%(4/48). Distant metastasis was 15%(7/48). Of the 43 patients with positive vaginal resection margins treated with EBRT and VOI, recurrence rate was 21%(9/43), while recurrence rate was 40%(2/5) in the EBRT only treated group. In 12 patients with positive parametrial margins, three patients (25%) had distant metastases. The most significant prognostic factor was lymph node metastasis. Complications resulting from radiotherapy occurred at a rate of 32%(19/60) and grade III complications occurred in three patients (5%). Conclusion : Postoperative radiotherapy can produce excellent pelvic control rates in patients with positive resection margins. In patients with positive vaginal margins, whole pelvic EBRT and BOI is recommended

Purpose: to evaluate the potential benefit of proton therapy and photon based intensity-modulated radiotherapy in comparison to 3-D conformal photon radiotherapy (3D-CRT) in locally advanced cervix cancer. Patients and methods: in five patients with advanced cervix cancer 3D-CRT (four-field box) was compared with intensity modulated photon (IMXT) and proton therapy (IMPT) as well as proton beam therapy (PT) based on passive scattering. Planning target volumes (PTVs) included primary tumor and pelvic and para-aortic lymph nodes. Dose-volume histograms (DVHs) were analyzed for the PTV and various organs at risk (OARs) (rectal wall, bladder, small bowel, colon, femoral heads, and kidneys). In addition dose conformity, dose inhomogeneity and overall volumes of 50% isodoses were assessed. Results: all plans were comparable concerning PTV parameters. Large differences between photon and proton techniques were seen in volumes of the 50% isodoses and conformity indices. DVH for colon and small bowel were significantly improved with PT and IMPT compared to IMXT, with D{sub mean} reductions of 50-80%. Doses to kidneys and femoral heads could also be substantially reduced with PT and IMPT. Sparing of rectum and bladder was superior with protons as well but less pronounced. Conclusion: proton beam RT has significant potential to improve treatment related side effects in the bowel compared to photon beam RT in patients with advanced cervix carcinoma. (orig.)

ABSTRACT Remodeling of the cervix is a critical early component of parturition and resembles an inflammatory process. Infiltration and activation of myeloid immune cells along with production of proinflammatory mediators and proteolytic enzymes are hypothesized to regulate cervical remodeling as pregnancy nears term. The present study standardized an approach to assess resident populations of immune cells and phenotypic markers of functional activities related to the mechanism of extracellular matrix degradation in the cervix in preparation for birth. Analysis of cells from the dispersed cervix of mice that were nonpregnant or pregnant (Days 15 and 18 postbreeding) by multicolor flow cytometry indicated increased total cell numbers with pregnancy as well as increased numbers of macrophages, the predominant myeloid cell, by Day 18, the day before birth. The number of activated macrophages involved in matrix metalloproteinase induction (CD147) and signaling for matrix adhesion (CD169) significantly increased by the day before birth. Expression of the adhesion markers CD54 and CD11b by macrophages decreased in the cervix by Day 18 versus that on Day 15 or in nonpregnant mice. The census of cells that expressed the migration marker CD62L was unaffected by pregnancy. The data suggest that remodeling of the cervix at term in mice is associated with recruitment and selective activation of macrophages that promote extracellular matrix degradation. Indices of immigration and activities by macrophages may thus serve as markers for local immune cell activity that is critical for ripening of the cervix in the final common mechanism for parturition at term.

In the 1940s, 1950s and 1960s, low doses of radiotherapy were used to treat benign uterine bleeding. The cases of two women who received this form of therapy and later developed gynaecological malignancies and had high-dose pelvic radiotherapy are presented. A 76-year-old woman with an International Federation of Gynecology and Obstetrics (FIGO) stage-II B squamous cell carcinoma of the cervix received external beam radiotherapy and intra-uterine brachytherapy and a 77-year-old woman with a FIGO stage-I B endometrial adenocarcinoma received adjuvant postoperative pelvic radiotherapy. Both women had a significant past history of low-dose-rate intra-uterine irradiation for dysfunctional uterine bleeding. Therefore the theoretical question of carcinogenesis was raised, and also the practical questions of what dose had previously been given and what further dose could be safely given with regard to normal tissue tolerance.

Schreiner, P.

1985-01-01

A cytological study was conducted covering 174 epidermoid uterine cervix carcinoma patients who had been given combined radiation therapy. The changes were assessed in the karyopyknotic index (KPI) as related to radiation therapy and the incidence of local relapses. At the limit KPI value of 10, the average reliability of the method for diagnosing persistence in the group under study was 83.0%. Patients showing KPI of more than 10 at six weeks following the termination of radical radiation therapy represent a poor prognosis group whereas those showing KPI values lower than 10 have good prognosis. The results show that no strict hormonal dependence of the KPI value exists in uterine ceervix carcinoma patients; only a different situation exists which is probably due to the tumor-organism interaction or to the metabolism of the tumor itself.

1998-07-01

Seventy-five squamous cell carcinomas of the uterine cervix and 10 controls were stained for Ulex Europaeus lectin 1 (UEA-1) and anti-CD31, and the results were analyzed with respect to patient age, clinical stage, tumor grade, and survival during a follow-up period of 1 to 13 years. The patients' mean age at the time of diagnosis was 47.8 years (range, 27 to 83). Seventeen patients died of disease, 2 had disease recurrence, and 51 patients remained free of disease; 5 patients were lost to follow-up. Twenty-eight cases (37.3%) showed focal membranous staining for UEA-1 and 9 cases (12%) showed a diffuse pattern; 38 cases (50.7%) were UEA-1 negative. Poor survival was related to diffuse membranous UEA-1 immunoreactivity (p = 0.02), age (p = 0.014), grade (p = 0.02), and stage (p = 0.0002). CD31-positive neoplastic cells displayed a cytoplasmic pattern. Fifteen cases (20%) had diffuse staining and another 15 (20%) stained focally; 45 cases (60%) were CD31-negative. The adjacent nonneoplastic epithelium and all 10 controls were uniformly negative for CD31. Variable staining of the endocervical epithelium and weak or negative staining of ectocervical epithelium for UEA-1 were observed. However, the epithelium in all controls was negative for UEA-1. Poor survival was related to both focal and diffuse staining for CD31 (p = 0.01 and p = 0.03, respectively). Staining by both UEA-1 and anti-CD31 retained its correlation with survival after exclusion of stage la tumors.

In a 86-year-old woman, basal cell carcinoma (BCC) arose on the skin with chronic radiation dermatitis. She, at the age of 46, received irradiation to the abdomen for cancer of the uterine cervix. Radiation source and dose were unknown. A verrucous eruption appeared on the irradiated field of the right abdomen, and gradually expanded. Histological examination showed that proliferation of tumor cells with adenoid and cystose structure extended to the epidermis. Electron microscopic study showed both clear and dark tumor cells, although dark cells were few in number. A review of the literature showed that BCC arising on the skin with chronic radiation dermatitis is uncommon in Japan. (Namekawa, K.)

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.

Basal cell carcinoma of the skin with areas of squamous cell carcinoma: a basosquamous cell carcinoma?

The diagnosis of basosquamous cell carcinoma is controversial. A review of cases of basal cell carcinoma showed 23 cases that had conspicuous areas of squamous cell carcinoma. This was distinguished from squamous differentiation and keratotic basal cell carcinoma by a comparative study of 40 cases of compact lobular and 40 cases of keratotic basal cell carcinoma. Areas of intermediate tumour differentiation between basal cell and squamous cell carcinoma were found. Basal cell carcinomas with ...

A comparative evaluation of the results of combined radiation therapy of two groups of patients with neglected forms of uterine cervix carcinoma is given. The groups were nearly identical as to the age, the presence of concomitant diseases, histological structure of the tumour and the extent of its spreading. The first group was treated according to an elaborated split course of radiation therapy, and the second by the conventional method. The analysis of the data obtained allows preference to be given to the split course method since with its use the incidence of radiation complications drops by 3.3 times and the immediate results improve by 1.2 times

Full Text Available Cervical cancer is one of the commonest types of cancers worldwide especially in developing countries. Intermediate filaments protein family has shown a role in the diagnosis of various cancers, but a few studies are available about the vimentin and cytokeratin roles in the cervical cancer. This case control study aimed to interpret the expression of vimentin and cytokeratin proteins in the development and progression of cervical cancer and its correlation with clinicopathological features. The cytoplasmic expression of vimentin was observed in 40% of cases, but not in inflammatory lesions of cervix. It was noticed that vimentin expression was increasing significantly with high grade of the tumour. Cytokeratin expression was observed in 48.33% and it was noticed that the expression was 62.5% in well differentiated (G1, 45% in moderately differentiated (G2, and 41.66% in poorly differentiated carcinoma, yet statistically insignificant. The expression of vimentin and cytokeratin proteins was not significantly associated with age groups. The current findings concluded a possible role of vimentin in the development and progression of cervical cancer and vimentin marker will be useful in the diagnosis and grading of cervical cancer.

Visual inspection followed by biopsy is the standard procedure for cancer diagnosis. Due to invasive nature of the current diagnostic methods, patients are often non-compliant. Hence, it is necessary to explore less invasive and rapid methods for early detection. Exfoliative cytology is a simple, rapid, and less invasive technique. It is thus well accepted by patients and is suitable for routine applications in population screening programs. Raman spectroscopy (RS) has been increasingly explored for disease diagnosis in the recent past. In vivo RS has previously shown promise in management of both oral and cervix cancers. In vivo applications require on-site instrumentation and stringent experimental conditions. Hence, RS of less invasive samples like exfoliated cells has been explored, as this facilitates collection at multiple screening centers followed by analysis at a centralized facility. In the present study, efficacy of Raman spectroscopy in classification of 15 normal and 29 abnormal oral exfoliated cells specimens and 28 normal and 38 abnormal cervix specimens were explored. Spectra were acquired by Raman microprobe (HE 785, Horiba-Jobin-Yvon, France) from several areas to span the pellet. Spectral acquisition parameters were: microscopic objective: 40X, power: 40 mW, acquisition time: 15 s and average: 3. PCA and PC-LDA of pre-processed spectra was carried out on a 4-model system of normal and tumor of both cervix and oral specimens. Leave-one-out-cross-validation findings indicate 73 % correct classification. Findings suggest RS of exfoliated cells may serve as a patient-friendly, non-invasive, rapid and objective method for management of cervix and oral cancers.

Results: The median age of the patients in this group was 47.5 years, with a range of 30–80 years. The major histological type of carcinoma among 40 cases is squamous cell carcinoma (SCC (in 90% of cases, and 10% had adenocarcinoma. Pathological staging of the carcinoma cervix showed stage Ib, IIa, IIb, and IVa (35%, 20%, 40%, and 5%. Tumor volume estimated on pathological specimens of 40 cases ranged from 230 cumm to 49,760 cumm with a mean of 14,844 cumm. 12 (30% cases had tumor volume more than 15,000 cumm, 12 (30% cases had tumor volume <5000 cumm and 16 (40% cases had tumor volume between 5000 and 15,000 cumm. 17% of the tumors with tumor volume <5000 cumm showed lymph node metastases, whereas 67% (out of 12cases of cases with tumor volume more than 15,000 cumm showed lymph node metastases. 67% of the tumors with tumor volume <5000 cumm showed 0/4 organs involvement, whereas all cases with tumor volume more than 15,000 cumm showed more than one organ involvement among vagina, uterus, parametrium or bladder/rectum. Fibronectin positivity was seen in 22 out of 44 cases (55%. Macrophages were seen surrounding the group of tumor cells by LN5 immunostaining. Conclusion: Tumor volume can be considered as an independent prognostic factor to assess the spread of the tumor. Cases with tumor volume <5000 cumm show low risk in terms of parametrial involvement and lymph node metastasis and those with tumor volume more than 15,000 cumm showed more organ spread. Fibronectin positivity carries some importance in low-risk cases. For macrophages, further detailed study needs to be carried out.

Attempting to improve local disease control in bulky primary or recurrent pelvic tumors, 29 patients with squamous cell carcinoma of the cervix were treated with concomitant chemotherapy and split-course hyperfractionated radiation therapy between April 1983 and August 1988. Cisplatin (CDDP) and 5-fluorouracil (5-FU) have been shown to be radiation enhancers; furthermore, CDDP, radiation therapy, and continuous-infusion 5-FU have elicited high local response rates in head and neck squamous cell carcinoma. A pilot study of cyclical week on/week off CDDP, continuous-infusion 5-FU, and hyperfractionated radiation therapy was developed. Radiation was administered at 116 cGy twice daily, Days 1-5, every other week for a median dose of 4600 cGy to a pelvic field, with paraaortic extension if indicated. Concomitant chemotherapy included CDDP 60 mg/m2 IV Day 1 and 5-FU 600 mg/m2 IV continuous infusion for 96 hr following CDDP infusion. Patients received a median of four cycles of combined treatment, and intracavitary or interstitial brachytherapy followed in 21 patients. Local pelvic response was achieved in 29 of 29 (100%): complete response (CR) in 19 of 29 (66%), partial response (PR) in 10 of 29 (34%). Among CR patients 10 of 19 (53%) were without evidence of disease at a mean follow-up of 29 (range 12-76) months. Five-year actuarial disease-free survival among complete responders was 65%. Of the 10 CR patients 2 failed in the pelvis, for a local control rate of 17/19 (89%). Chemotherapy-related and acute radiation morbidity was minimal but 2 patients required surgical correction of radiation injury. Aggressive combination of split-course hyperfractionated radiation therapy with radiation enhancers resulted in promising local control of bulky pelvic tumor, with an acceptable complication rate, in this otherwise very poor prognostic group of patients.

Adenocarcinoma cervix is an uncommon histological subtype of carcinoma cervix; further incidence of skeletal muscle metastases is even rarer. We report the identification of extensive fluorodeoxyglucose (FDG) avid metastatic skeletal muscle deposits in a known case of adenocarcinoma cervix. The largest lesion representative of muscle deposit in the right deltoid was histopathologically confirmed to be metastatic poorly differentiated carcinoma. This report also serves to highlight the importance of 18 F-FDG positron emission tomography/computed tomography (CT) as compared to conventional imaging modalities such as CT and ultrasonography and comments better over the description of invasiveness as well as the extent of disease in carcinoma cervix

A case of postirradiation sarcoma is described. The tumor, a malignant fibrous histiocytoma, occurred in the radiation field 11 years following postoperative external beam radiation therapy (7,000 rad) for carcinoma of the cervix. Reports of postirradiation malignant fibrous histiocytoma are rare, and the occurrence of this neoplasm following treatment for cervix cancer has not previously been described. The literature concerning postirradiation bone and soft tissue sarcomas is briefly reviewed, with special attention to malignant fibrous histiocytomas. (author)

Low-stage uterine cervix carcinoma can be treated by either surgery, radiation therapy or combined treatments with high cure rates ranging from 90 to 95 % for stage IB1 tumors. However, the standard treatment, combining external beam plus intracavitary radiation, fails to control the progression of the disease in 35 to 90 % of patients with locally advanced cervical cancer. No substantial improvements have been made in the treatment of these tumors in the past two decades. The addition of concurrent 5-FU in a phase III study failed to improve the results in the overall patient population, but the five-year DFS was significantly better in a subset of patients (tumor > 5 cm and IB/IIA or medial parametrial IIB disease). Concurrent chemo-radiation and adjuvant chemotherapy with epirubicin showed, in a phase III study, a significant longer DFS in patients treated with chemotherapy despite the same long-term local tumor control. After many phase II studies, five phase III studies have recently demonstrated a 40 to 60 % reduction in the relative risk of recurrence with cisplatin containing chemo-radiation. Across these studies, the risk of death was reduced by 30 to 50 %. The benefit was less clear in patients with stages III-IV tumors than in patients with lower stages associated with poor prognostic factors. Hematologic and gastrointestinal toxicity of chemo-radiation was greater than that of radiotherapy alone. However, late side effects were similar in the different treatment groups. These results must be confirmed with a longer follow-up. The importance of concurrent chemotherapy during the brachytherapy procedure should be analyzed. It has yet to be determined which chemotherapy regimen achieves the most favorable therapeutic ratio. (authors)

Background and purpose: This survey aimed to document practices of Canadian radiation oncologists performing gynecologic brachytherapy for carcinoma of the cervix and to determine what the effect of the phasing-out of LDR after-loading systems from the commercial market is having on practice. Materials and methods: A 26-item questionnaire was developed to survey various aspects of brachytherapy practice to include: number of patients treated, prescription points/volume, dose and fractionation, timing, critical structure delineation, expected changes due to the phasing-out of support for low dose rate systems, and support for the development of national guidelines. A link to a web-based survey collection instrument was emailed to each radiation oncologist in Canada practicing gynecologic brachytherapy. Results: A 67% response rate was achieved in this web-based survey. Radiation oncologists currently using HDR brachytherapy are most commonly delivering 5 fractions of 6 Gy in addition to an EBRT dose of 45 Gy in 25 fractions. The median total dose equivalents to Point A was 82.9 Gy for both early and advanced disease. In response to the announcement by a major vendor that they would be phasing-out service for a popular LDR after-loader, 49% of Canadian radiation oncologists who practice brachytherapy for cervix cancer are changing to an HDR technique with a further 9% changing to a PDR technique. Eighty-six percent of respondents would support the development of national guidelines for cervix brachytherapy in Canada. Conclusions: Variation in practice exists in Canada in brachytherapy for cervix cancer. Many centers are in the process of phasing-out LDR techniques in response to the withdrawal of commercial support for these systems. Support for the development of Canadian national guidelines is high.

Full Text Available INTRODUCTION Radiotherapy is the standard treatment in locally advanced (IIB-IVA and early inoperable cases. The current standard of practice with curable intent is concurrent chemoradiation in which intracavitary brachytherapy is an integral component of radiotherapy. This study aims at assessing the efficacy of HDR ICBT (High-dose rate intracavitary brachytherapy in terms local response, normal tissue reactions, and feasibility. METHODS AND MATERIALS A total of 20 patients of stage IIIB cancer of the uterine cervix were enrolled in the study and were planned to receive concurrent chemotherapy weekly along with EBRT (external beam radiotherapy to a dose of 50 Gy/25 Fr. Suitability for ICBT was assessed at 40 Gy/20 Fr. 6/20 patients were suitable at 40 Gy and received HDR ICBT with a dose of 5.5 Gy to point A in 4 sessions (5.5 Gy/4 Fr. The remaining 14/20 patients completed 50 Gy and received HDR ICBT with a dose of 6 Gy to point A in 3 sessions (6 Gy/3 Fr. RESULTS A total of 66 intracavitary applications were done and only one application required dose modification due to high bladder dose, the pelvic control rate was 85% (17/20. 10% (2/20 had stable disease and 5% (1/20 had progressive disease at one year of follow up. When toxicity was considered only 15% developed grade I and grade II rectal complications. Patient compliance and acceptability was 100%. Patients were very comfortable with the short treatment time as compared with patients on LDR ICBT (low-dose rate intracavitary brachytherapy treatment interviewed during the same period. CONCLUSION This study proves that HDR brachytherapy is efficacious and feasible in carcinoma of cervix stage IIIB. It also proves that good dose distribution can be achieved with HDR intracavitary facility by the use of dose optimization. The short treatment time in HDR ICBT makes it possible to maintain this optimised dose distribution throughout the treatment providing a gain in the therapeutic ratio and

Abstract In carcinoma, such as of the lung, the histological subtype is important to select an appropriate therapeutic strategy for patients. However, carcinomas with poor differentiation cannot always be distinguished on the basis of morphology alone nor on clinical findings. Hence, delineation of poorly differentiated adenocarcinoma and squamous cell carcinoma, the 2 most common epithelial-origin carcinomas, is pivotal for selection of optimum therapy. Herein, we explored the potential utility of trefoil factor 3 (TFF3) as a biomarker for primary lung adenocarcinoma and extrapulmonary adenocarcinomas derived from different organs. We observed that 90.9% of lung adenocarcinomas were TFF3-positive, whereas no expression of TFF3 was observed in squamous cell carcinomas. The subtype of lung carcinoma was confirmed by four established biomarkers, cytokeratin 7 and thyroid transcription factor 1 for adenocarcinoma and P63 and cytokeratin 5/6 for squamous cell carcinoma. Furthermore, expression of TFF3 mRNA was observed by quantitative PCR in all of 11 human lung adenocarcinoma cell lines and highly correlated with markers of the adenocarcinomatous lineage. In contrast, little or no expression of TFF3 was observed in 4 lung squamous cell carcinoma cell lines. By use of forced expression, or siRNA-mediated depletion of TFF3, we determined that TFF3 appeared to maintain rather than promote glandular differentiation of lung carcinoma cells. In addition, TFF3 expression was also determined in adenocarcinomas from colorectum, stomach, cervix, esophagus, and larynx. Among all these extrapulmonary carcinomas, 93.7% of adenocarcinomas exhibited TFF3 positivity, whereas only 2.9% of squamous cell carcinomas were TFF3-positive. Totally, 92.9% of both pulmonary and extrapulmonary adenocarcinomas exhibited TFF3 positivity, whereas only 1.5% of squamous cell carcinomas were TFF3-positive. In conclusion, TFF3 is preferentially expressed in adenocarcinoma and may function as an

Radiotherapy is the most efficient method of treatment of the carcinoma of the cervix. It is usually accepted also that the incidence of some sequels is justifiable as soon as it be kept in the lowest level possible. Trying to find out if this has correlation with the incidence of hypogastrium subcutaneous fibrosis in the cervix carcinoma treatment, 96 patients treated at Instituto de Radioterapia Osvaldo Cruz were analysed. The incidence of fibrosis was related to treatment techniques, tumor dose and TDF factor. The results indicated that TDF factor is the only one that can be directly related to the incidence of this sequel. The critical value for TDF factor was fixed at 110, and any increase on it elevates the fibrosis incidence by a factor of 5. Finally it is recommended that the TDF calculation should be utilized as the main factor in the selection of the several parameters involved in this kind of treatment. (F.R.) [pt

Between January 1980 and December 1988, 373 patients with carcinoma of the uterine cervix were treated at the Department of Radiology, Tokushima University Hospital. Of the 373 patients, 229 were treated by radiotherapy alone, and 144 were treated by post-operative radiotherapy. The incidence of skeletal metastasis was 6.4%, 24 patients out of 373. Ten of these patients were treated with radiotherapy alone, and 14 with radical surgery and radiotherapy. Nineteen patients belonged in the early clinical stage (stage Ia through stage IIb). Lesions of skeletal metastases were usually detected within 2 years after the initial treatment, and the most common site of skeletal metastasis was the pelvic bone, followed by the lumbar spine. Most patients with skeletal metastases were treated by radiotherapy, chemotherapy, and combined radio- and chemotherapy. Severe pain due to skeletal metastasis was relieved by radiotherapy and combined therapy, but no method of treatment could extend the prognosis. (author)

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%.

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

Uterine cervix carcinomas spread by direct local extension, lymphatic permeation and hematogenous dissemination. Their metastatic foci are closely related to iliopsoas compartment anatomically no matter what the pattern of spread is. Therefore, iliopsoas involvement in uterine cervix cancer may occur frequently. The authors reviewed pelvis CT of 218 cervix cancer patients for recent one year from March 1986 to February 1987 at Seoul National University Hospital. Among them, 10 cases showed iliopsoas involvement. Pattern of iliopsoas involvement was classified into four types: infiltrative type (three cases), localized mass type (three cases), mass with bone destruction type (two cases), paraaortic lymphadenopathy type (two cases). In all cases except 3 cases of infiltrative type, lymphadenopathy or bone metastasis adjacent to iliopsoas lesion was identified. And this finding suggested that the route of iliopsoas involvement in cervix cancer would be secondary infiltration from metastatic focus of adjacent lymph node or bone. Recognition of iliopsoas involvement of cervix caner may prevent misdiagnosis and predict the degree of disease dissemination

Purpose: To see if changes in tumor/blood glutathione (GSH) levels after one fraction of radiotherapy can be correlated with the treatment response in patients with carcinoma of the uterine cervix. Methods and Materials: The study was done on 45 patients with squamous cell carcinoma of the uterine cervix, FIGO Stages IIB (17 patients) and IIIB (28 patients). Stage IIB patients received 35 Gy of cobalt-60 external radiotherapy (RT) in 16 fractions over 4 weeks with a concurrent high-dose-rate intracavitary dose of 8.5 Gy to point A once a week. Stage IIIB patients were given 45 Gy of RT in 20 fractions over 5 weeks, followed by two doses of intracavitary therapy once a week. Blood and tumor samples were collected before and after one dose of RT and GSH was estimated. Tumor response was assessed clinically at 1 month after treatment. Results: Glutathione levels in both blood and tumor showed a significant decrease after one fraction of RT, but the degree of decrease varied among patients. There was a good correlation between the extent of GSH decrease and the tumor response. All patients who had complete response (CR) (seven Stage IIB and eight Stage IIIB) showed ≥70% decrease in both tumor and blood GSH, while those who had <50% regression (NR) (five Stage IIB and 13 Stage IIIB) showed <50% decrease in GSH. The partial responders recorded an intermediate level (50-70%) of depletion in blood and tumor GSH. Conclusions: The results indicate that the changes in tumor/blood GSH levels after one fraction of RT could serve as an index of tumor response to therapy and may help in identifying radioresistant tumors, at least in the case of cervix carcinoma

Gynecologic cancer records of 4,238 patients treated between 1956 and 1974 were reviewed. Sixteen patients developed neoplasia in the cervix or vagina 10 or more years following pelvic irradiation. Three patients had squamous carcinoma in situ; the other 13 patients had invasive squamous cancer involving the upper vagina. Only 1.26 percent of invasive carcinoma of the cervix treated by radiation therapy from 1956 to 1966 presented with a late or recurrent or new primary tumor involving the vagina or cervix 10 or more years after primary treatment. The authors conclude that the risk of developing radiation-induced carcinoma in the upper vagina or cervix following pelvic irradiation is low. Follow-up Pap smears are indicated for all patients treated for cervical or vaginal malignancies by radiation therapy in order to detect vaginal neoplasia as well as recurrent carcinoma of the cervix

To evaluate magnetic resonance imaging (MRI) in the planning of optimal treatment- radiotherapy or radical surgery in pregnant patients with invasive carcinoma of the cervix. Material and methods. Four patients with invasive carcinoma of the cervix in pregnancy underwent MRI for evaluation of the tumor extent with an emphasis on parametrial invasion and pelvic lymph node metastases. In all 4 patients the diagnosis of carcinoma of the cervix was established in the first trimester of pregnancy. Clinical stage I B was confirmed in two patients, II B in one patient and I A in one patient. The first patient with stage I B disease was treated with radical Wertheim 's hysterectomy. The second patient with stage I B was found inoperable due to bladder involvement not revealed by the MRI. This patient was subsequently treated with radiotherapy. The microscopic examination confirmed deep infiltration of the cervical stroma as detected by preoperative MRI in the radically operated case and the presence of metastases to the pelvic nodes in both patients, also detected by MRI. The third patient with stage IIB disease was treated with external beam irradiation to the pelvis and intracavitary brachytherapy. In the course of follow-up ranging from 9 to 35 months one patient recurred in the paraaortic region and was subsequently treated with surgery and adjuvant chemotherapy. MRI is a useful tool for noninvasive staging of pregnant patients with invasive carcinoma of the cervix. All data suggesting a subclinical spread of the tumor outside the cervix may be helpful in selecting the optimal method of treatment. (author)

1987-01-01

A commercial ''SCC RIABEAD'' kit for immunoradiometric assay of squamous cell carcinoma related antigen (SCC antigen) was fundamentally and clinically evaluated. Laboratory performance was satisfactory for intra-assay and inter-assay reproducibility, recovery, and dilution, with rapid and simple measurement techniques. Seropositivity for SCC antigen was significantly higher for squamous cell carcinoma of the liver and uterine cervix than the other histology types. In the case of cervical squamous cell carcinoma, it increased with progressing disease. Post-treatment serum levels of SCC antigen returned to negative. SCC antigen is considered to be a useful tumor marker for these diseases. There was a good correlation between the measurement values obtained from the present and conventional (SCC RIAKIT) assays. The present assay remarkably decreased false-positive cases of pulmonary benign diseases. The results showed a ''SCC RIABEAD'' to be a favorable kit for immunoradiometric assay of SSC antigen, as compared with conventional assay kit. (Namekawa, K.)

Objective: To explore the clinical significance of changes of serum IGF-II, SCC and CYFRA21-1 levels after operation in patients with carcinoma uterine cervix. Methods: Serum levels of IGF-II, SCC and CYFRA21-1 were determined with RIA repeatedly in 31 patients with carcinoma of uterine cervix (before operation 1 month after operation and 6 month after operation) and once in 35 controls. Results: Before operation,serum levels of IGF-II, SCC and CYFRA21-1 in the patients were significantly higher than those in the controls (P<0.01). One month after operation all the serum levels were approaching normal. Six month later,the levels in the patients without recurrence remained normal. However, the levels in the 6 patients with recurrence returned to those before operation again. Conclusion: Changes of serum IGF-II, SCC and CYFRA21-1 levels are closely related to the tumor burden and may be of prognostic importance. (authors)

Anemia is very commonly seen in most of the malignancies including cancer cervix. Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. At our center, carcinoma cervix accounts for approximately 8-10% of all malignancies. The objective of this study is to see the impact of anemia in the treatment of cancer cervix. In the present study, we collected data of treatment results of FIGO stage II and III cancer cervix patients retrospectively treated in years of 2009-10. We have tried to assess the outcome of results in patients whom haemoglobin (Hb) level < 10 gm/dl and e''10 gm/dl. Out of 200 patients of disease with baseline Hb less than 10 gm/dl, 80(40%) patients had residual disease after 4 weeks of completion of treatment. Out of 168 patients with baseline Hb more than 10 gm/dl, 42(25%) had residual disease (p-0.0012 i.e highly significant). Our study shows that there is a good disease control at local site in patients with higher pretreatment Hb level. Effect of pretreatment Hb on treatment outcome in terms of overall survival, disease free survival, and local relapse free survival along with effect on corrective measures should be studied in detail.

To evaluate local disease control and early complications of concomitant brachytherapy with external beam-radiotherapy in early stage carcinoma cervix. Fifty patients of early stage carcinoma cervix (FIGO-IB/IIA) were randomly divided into study group concomitant external beam irradiation (EBRT) and HDR-ICBT (intra-cavitary brachytherapy, xrt = 50 Gy/25 Fr, HDR 5.2 Gy*5 Fr) and the control group EBRT followed by HDR-ICBT (xrt = 50 Gy/25 Fr, HDR 7.5 Gy*3 Fr). Acute reactions and local disease response were compared between treatment and at 6-month follow up. Median overall treatment times were 38 and 61 days in the study and the control groups, respectively. Acute skin reactions and diarrhea were more in the study but manageable. At the completion of the study, there were 80 and 68 % complete responses, 16 and 20 % partial responses, 0 and 8 % stable diseases in the study group and the control group, respectively. Response was better in the study group but statistically insignificant. Larger number of patients and longer follow up are required to arrive at concrete conclusion.

To study the magnitude of radiation cystitis following radiation therapy for carcinoma cervix, and propose an algorithm to decide on early diversion, with or without vesicovaginostomy. Women who developed radiation cystitis following radiotherapy for carcinoma cervix from January 1998 to December 2011 were included in this retrospective study. Electronic hospital records were analysed to document the presence of radiation cystitis. All women who developed evidence of radiation-induced cystitis, according to the common toxicity and Radiation Therapy Oncology Group criteria, were included in the study. We looked at transfusion requirements, number of hospital admissions, quality of life and cost involved. Chi-square tests were done where applicable. SPSS version 16 was used for analysis. Of the 902 patients who received radiation for carcinoma cervix in the 13-year period, 62 (6.87%) developed grade 3/4 cystitis. Twenty-eight of them underwent ileal conduit diversion, with 18 undergoing concomitant vesicovaginostomy. When compared with the patients who did not have diversion, the transfusion requirements, number of hospital admissions and quality of life had a statistically significant difference. Cost analysis of early diversion too showed a marginal benefit with early diversion. The limitation of the study was that it was retrospective in nature. In radiation cystitis, multiple hospital admissions and consequential increase in cost is the norm. In severe disease, early diversion is a prudent, cost-effective approach with good quality of life and early return to normal activity. © 2014 Royal Australasian College of Surgeons.

The adult uterine cervix may exhibit a wide variety of pathologic conditions that include benign entities (eg, cervicitis, hyperplasia, nabothian cysts, cervical polyps, leiomyomas, endometriosis, and congenital abnormalities) as well as malignant lesions, particularly cervical carcinoma. In addition, lesions that arise in the uterine body may secondarily involve the cervix, such as endometrial carcinoma and prolapsed intracavitary masses. Many of these conditions can be identified and characterized at ultrasonography (US), which is considered the first-line imaging examination for the female pelvis. However, examination of the cervix is often cursory during pelvic US, such that cervical disease may be overlooked or misdiagnosed. Transabdominal US of the cervix may not afford sufficient spatial resolution to depict cervical disease in many patients; therefore, endovaginal US is considered the optimal technique. Use of supplemental imaging techniques, particularly the application of transducer pressure on the cervix, may be helpful. This review describes the normal appearance of the cervix at US, the appearance of cervical lesions and conditions that mimic abnormalities at US, and optimal US techniques for evaluation of the cervix. This information will help radiologists detect and diagnose cervical abnormalities more confidently at pelvic US. Online supplemental material is available for this article. (©)RSNA, 2016.

Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

In 1979 the Cancer Control Agency of British Columbia changed from radium to remote controlled afterloaded caesium in the treatment of carcinoma of the cervix. In 3 years prior to the change, 139 patients received radium as part of their treatment and in the 3 years after the change, 158 patients received caesium. Overall referral patterns, patient and cancer demographics, and treatment policies were stable throughout the 6-year period. Radiotherapy technique, dose, dose distribution and dose rate were comparable for both radium and caesium treated patients. The results of treatment in the two time periods showed no difference in survival, local tumour control or complications. The use of afterloading has not compromised treatment results and has allowed better nursing care for patients and protection from radiation for all staff. (author)

to investigate the expression of the membrane-bound matrix metalloproteinase MT1-MMP (MMP-14), its tissue inhibitor TIMP-2, and the proMMP-14 activator furin in the corpus uteri from the vaginal wall to the bottom of the uterine cavity in squamous cell carcinoma of the cervix (SCCC). Hysterectomy material was examined in patients with SCCC. Reverse transcriptase polymerase chain reaction (RT-PCR), immunohistochemistry (IHC), and enzyme assays were used. In SCCC, higher levels of MMP-14 expression were established in tumor cells, as evidenced by IHC (+3) and RT-PCR. IHC showed that the expression of MMP-14 was absent or insignificant in the normal uterine endometrial and myometrial tissues. However, that of MMP-14 mRNA was also found in the normal tissues to the bottom of the uterine cavity. Furin activity in the tumor was much higher than that in normal tissues. IHC indicated that TIMP-2 expression was low or absent in both the tumor and normal tissues. The expression of TIMP-2 mRNA was sufficiently obvious in both the tumor and normal tissues to the bottom of the uterine cavity. In SCCC, MMP-14 expression was substantially increased in tumors. The expression of MMP-14 and regulators of its activity is aimed at enhancing the tumor destructive (invasive) potential in the pericellular space and can occur (be induced) in the morphologically normal uterine tissue apparently with involvement of signaling through the epithelial-mesenchymal interaction. Data are important for understanding the role of MMP-14 in the development of a multistage process of carcinogenesis and may have prognostic value and an impact on therapeutic strategy for the patient.

To assess the clinical roles of [ 18 F]fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) performed 2-3 months after completion of concurrent chemoradiotherapy (CCRT), along with pretherapy characteristics, in patients with advanced squamous cell carcinoma of the uterine cervix enrolled in a prospective randomized clinical trial. Posttherapy PET/CT in patients with advanced FIGO stage or positive pelvic or para-aortic lymph node (PALN) defined on pretherapy PET/CT was classified as positive, equivocal, or negative. Overall survival (OS) rates between patients with different PET/CT results are compared. Pretherapy characteristics are examined for association with posttherapy PET/CT results and for prognostic significance in patients with equivocal or negative PET/CT. PET/CT scans (n = 55) were positive, equivocal and negative in 9, 13 and 33 patients, respectively. All patients with positive scans were confirmed to have residual or metastatic disease and died despite salvage therapies. There is a significant OS difference between patients with positive and equivocal scans (P PET/CT (P = .033) and predicts a poorer survival in patients with equivocal or negative posttherapy PET/CT (P PET/CT 2-3 months posttherapy implies treatment failure and novel therapy is necessary to improve outcomes for such patients. A more intense posttherapy surveillance may be warranted in patients with positive pretherapy PALN.

We evaluated the longer-term efficacy and safety of concurrent chemoradiotherapy (CCRT) incorporating high-dose-rate intracavitary brachytherapy (HDR-ICBT) with a lower cumulative radiotherapy (RT) protocol and analyzed prognostic risk factors for survival among patients with International Federation of Gynecology and Obstetrics (FIGO) stage III-IVA squamous cell carcinoma (SCC) of the cervix. Ninety-nine patients with FIGO stage III-IVA SCC of the cervix between 1997 and 2008 were treated with CCRT using cisplatin 20 mg/m 2 for 5 days every 3 weeks or 40 mg/m 2 weekly. Acute and late toxicities were evaluated. Overall survival (OS) and disease-free survival (DFS) were estimated by the Kaplan-Meier method. The Cox proportional hazard model was used for multivariate analysis. Median age was 53.5 years. Median follow-up period was 58 months (range 6-170 months). Pathologically complete response was achieved in 93 patients (96.9%). The 5-year OS and DFS were 72.0 and 69.3%, respectively. The 5-year local and distant DFS were 83.0 and 75.1%, respectively. Thirty-one patients (31.3%) experienced recurrence. Multivariate analysis showed that tumor size and pretreatment hemoglobin level remained an independent risk factor for OS and DFS. Acute toxicity was moderate. In terms of late adverse effects, 2 patients (2.0%) suffered from grade 4 late intestinal toxicity because of radiation enterocolitis, with both requiring intestinal surgery. Our study demonstrates that the CCRT schedule in patients with FIGO stage III-IVA SCC is efficacious and safe. In addition, the assessment of tumor size and pretreatment anemia can provide valuable prognostic information. (author)

Full Text Available A mesonephric adenocarcinoma of the cervix is a very rare tumor deriving from remnants of the mesonephric duct. Differential diagnosis from other cervical carcinomas is difficult and little is known regarding its biological behavior, prognosis, and the optimal management strategy. We present a case of a mesonephric adenocarcinoma of the cervix with a comprehensive review of the existing literature. In this case a 66-year-old woman presented with postmenopausal vaginal bleeding. She was diagnosed with a FIGO stage IIB mesonephric adenocarcinoma of the cervix and treated with neoadjuvant chemoradiotherapy and a Wertheim hysterectomy. The recovery from surgery was uneventful and the patient remains with no evidence of disease with 2 years of follow-up.

Analytic study of regional changes in carcinoma of the cervix uteri following linac irradiation

International Nuclear Information System (INIS)

Yamashita, Michitaka

1978-01-01

Histological evaluation was made on regional changes in 60 cases of carcinoma of the cervix uteri following Linac therapy which was employed prior to any other therapy. Correlation between this result and the effect of irradiation on the primary lesion was evaluated. Changes in carcinomatous cells following Linac irradiation were remarkably found in swelling, vacuolation hyalinization and decrease of nuclear division of the cytoplasm, and in swelling, vacuolation, concentration, and clasmatosis of nuclei, and also in swelling of nucleus. Changes in the interstice were hyperplasia of the surrounding connective tissues which became remarkable as a dose of the irradiation increased. However, the changes in the interstice seemed to appear a little late after the changes in the carcinomatous cells occurred. The density of blood-vessel distribution remained high until the irradiation of 3000r, and it became lower following the irradiation of 3000r or more. Thickening of the blood-vessel wall and obstruction of the blood-vessel cavity were marked following the irradiation of 3000r. Infiltration of the lymphoid cells was most advanced following the irradiation of 3000r. When the effectiveness of irradiation and histological changes were compared, there was a highly significant difference (p<0.01) in swelling of nuclei between remarkably effective cases and ineffective cases following the irradiation of 1000r or 2000r. There were significant differences (p<0.05) in swelling of the cytoplasm following the irradiation of 1000r or 2000r, clasmatosis of the nuclei following the irradiation of 3000r, the density of blood-vessel distribution before the therapy and following the irradiation of 2000r, and infiltration of lymphoid cells following the irradiation of 1000 or 3000r between two.

Uterosacral space involvement in locally advanced carcinoma of the uterine cervix

International Nuclear Information System (INIS)

1998-01-01

Purpose: Radiation therapy is the standard management for locally advanced cervical cancer, but it has not yielded fully satisfactory results; a relatively high incidence of local failure remains. Standard radiation therapy techniques combine external beam radiation and brachytherapy generating a homogeneously composite dose distribution covering the lateral parametria but may not be adequate in the uterosacral and perirectal areas due to the spatial arrangement of intracavitary system and the constraints of rectal tolerance. We hypothesize that these dosimetric characteristics might lead to a higher incidence of central/marginal failures when the uterosacral space is involved by locally advanced carcinoma of uterine cervix. Methods and Materials: Between January 1970 and December 1989, 343 patients with clinical Stage IIIB cervical cancer were treated at the Mallinckrodt Institute of Radiology with radiation therapy alone. We identified 83 patients with clinical evidence of tumor in the uterosacral region; the remaining 260 patients either did not have uterosacral involvement or were unspecified. The dose of external beam irradiation ranged from 18.02 to 33.20 Gy to the central pelvis and 48.22 to 59.40 Gy to the lateral parametrium. The average total dose, including brachytherapy contribution, to point A and the lateral pelvis was 80.30 to 86.46 Gy and 60.50 to 73.40 Gy, respectively. External beam dose to the lateral parametria was, on average, 10 Gy higher in patients with uterosacral involvement. Results: We categorized the patterns of pelvic failure into central/marginal (including medial parametrium) and lateral parametria. The cumulative incidence of central/marginal failure at 5 years was significantly higher in the group of patients with uterosacral involvement (36% compared with 21% for patients without uterosacral involvement or unspecified) (p = 0.002). Lateral parametrial failure was similar for patients with and without uterosacral involvement (39

Conclusion: A literature review revealed that this was a rare case of combined ABC–SCC associated with HPV 31 infection. In this case, the ABC component did not affect the tumor stage because it was confined to the cervix. However, we must avoid overestimating the clinical stage because the ABC component is thought to be a benign lesion.

Purpose: A review of the Patterns of Care Studies Process Survey data on carcinoma of the cervix conducted on patients in 1978, 1983, and 1988-89 was carried out to identify changes or trends in the demographics, evaluation, and treatment that might have occurred over this time period. Methods and Materials: Patterns of Care Studies conducted surveys on patients treated by radiation therapy for cervical carcinoma in 1978, 1983, and 1988-89. These surveys have compiled demographic and treatment data on a total of 993 patients. There is outcome data for the 1978 and 1983 surveys, but not for the 1988-89 survey because follow-up has not been collected yet. The demographic and treatment delivery data on all three surveys has been reviewed and analyzed and is the subject of this study. Results: There was no difference in the age distribution at the time of diagnosis of the patients in these surveys. The percentage of black patients remained constant in the three surveys, 19%, 17%, and 21%, respectively. The percentage of white patients was 76%, 78%, and 67%, but that of nonwhite/nonblack patients was 3%, 4%, and 12% (p 60 Co units decreased from 35 to 2% from the first to the third survey [6 to 0% for short source-surface distance (SSD) 60 Co units]. Point dose calculations for the intracavitary therapy increased from 78% in the 1978 survey to 95% in the third survey. As determined by the total dose delivered to the paracentral points, more patients (75.1%) were treated according to the Patterns of Care recommended guidelines in the 1988-89 survey than in the 1983 survey (63.6%). Chemotherapy was given to 12% of the patients undergoing radiation therapy during the period of the third survey, but these data are not available for the first and second surveys. Conclusion: Review of the Carcinoma of the Cervix Patterns of Care studies discloses significant changes in the demographics, patient evaluation, and radiation therapy techniques during the period of the studies.

The prospective record of acute and late toxicity after treatment of cervix carcinomas is a part of the description of treatment outcome as well as local control and survival. Due to the large number of scales and glossaries used, the comparison of the results from one study to another is often difficult. The French-Italian syllabus seems to be the most reliable scale, providing implementation of quality of life assessment. The main predictive factor of complications, which is not related to the treatment type, is the previous history of abdominal or pelvic surgery. The incidence and severity of complications occurring after surgery are related to the surgical procedure and to the amount of peri-uterine tissues removed. The increase in dose and volume of external irradiation and brachytherapy and the increase in dose rate of the low-dose rate brachytherapy are responsible for the radiotherapeutic morbidity. The significant decrease of severe complication rates during the last 15 years was obtained by the implementation of individual adjustments in treatment planning. The treatment strategies of early bulky and advanced carcinomas are changing. Concurrent radiotherapy and chemotherapy is becoming a standard, but its late toxicity needs to be documented by a longer follow-up. The optimisation of radiation therapy should remain a reference to evaluate the outcome and morbidity of the new combined strategies: the addition of chemotherapy will never compensate for less than optimal radiotherapy/brachytherapy planning.

From June, 1972, to December, 1976, 40 patients with FIGO (International Federation of Gynaecology and Obstetrics) Stage IIB carcinoma of the uterine cervix were entered into a prospective, double-blind, randomized study to evaluate the possible radiation-potentiating properties (i.e., improved survival) of the S-phase cell cycle-specific inhibitor of DNA synthesis, hydroxyurea. All patients were documented to be without aortic lymph node metastasis by pretherapy staging para-aortic lymphadenectomy. All 40 patients were followed up for longer than 5 years (5.2 to 9.2 years) or until death. The double-blind code was not broken until all patients had been followed up for a minimum of 2 to 5 years. Leukopenia (white blood cell count less than 2,500 mm3) was significantly increased in the patients given hydroxyurea as compared to those given placebo (P less than 0.0001). There was no statistically significant difference relative to anemia, thrombocytopenia, radiation-induced skin reaction, and radiation-induced intestinal reaction between the patients given placebo or those given hydroxyurea. Life-table survival for the patients given hydroxyurea was 94% as compared to 53% for the patients given placebo (P . 0.006). Only one (5%) patient given hydroxyurea died of cervical cancer. Of the other patients who died in the group given hydroxyurea, all were confirmed by postmortem examination to have been without recurrent cervical cancer. In contrast, 45% (nine) of the patients given placebo died of cervical cancer

Cervical cancer continues to be an important worldwide health problem for women. Up to 35% of patients who are diagnosed with and appropriately treated for cervical cancer will recur and treatment results are poor for recurrent disease. Given these sobering statistics, development of novel therapies for cervical cancer remains a high priority. We evaluated the expression of Tissue Factor (TF) in cervical cancer and the potential of hI-con1, an antibody-like-molecule targeted against TF, as a novel form of immunotherapy against multiple primary cervical carcinoma cell lines with squamous- and adenocarcinoma histology. Because TF is a transmembrane receptor for coagulation factor VII/VIIa (fVII), in this study we evaluated the in vitro expression of TF in cervical carcinoma cell lines by immunohistochemistry (IHC), real time-PCR (qRT-PCR) and flow cytometry. Sensitivity to hI-con1-dependent cell-mediated-cytotoxicity (IDCC) was evaluated in 5-hrs- 51 chromium-release-assays against cervical cancer cell lines in vitro. Cytoplasmic and/or membrane TF expression was observed in 8 out of 8 (100%) of the tumor tissues tested by IHC and in 100% (11 out of 11) of the cervical carcinoma cell lines tested by real-time-PCR and flow cytometry but not in normal cervical keratinocytes (p = 0.0023 qRT-PCR; p = 0.0042 flow cytometry). All primary cervical cancer cell lines tested overexpressing TF, regardless of their histology, were highly sensitive to IDCC (mean killing ± SD, 56.2% ± 15.9%, range, 32.4%-76.9%, p < 0.001), while negligible cytotoxicity was seen in the absence of hI-con1 or in the presence of rituximab-control-antibody. Low doses of interleukin-2 further increased the cytotoxic effect induced by hI-con1 (p = 0.025) while human serum did not significantly decrease IDCC against cervical cancer cell lines (p = 0.597). TF is highly expressed in squamous and adenocarcinoma of the uterine cervix. hI-con1 induces strong cytotoxicity against primary cervical cancer cell

Purpose: To evaluate magnetic resonance imaging (MRI) in the planning of radiation therapy for patients with carcinoma of the cervix treated with a four-field technique. Methods and Materials: Between May 1994 and February 1995, 18 patients with carcinoma of the cervix were entered in the study (1 T1 N-; 2 T2a N-; 1 T2b NO; 10 T2b N-; 2 T2b N+; 2 T3b N+). Node status was assessed by a laparoscopic pelvic lymphadenectomy. During the first step, all the patients were simulated with an isocentric four-field pelvic technique. In one group (11 patients) simulation was done based on clinical examination, computed tomography (CT), and standard guidelines. In the second group (seven patients) simulation was based on clinical examination, CT, and with the help of diagnostic MRI, which was available at that time. During the second step, MRI in treatment position with skin markings of the isocenter of the radiation fields was then performed in every patient. During the third step, in each patient, the simulated radiation fields were correlated with the MRI defined target volume by superimposing them on midsagittal and midcoronal MR images. The adequacy of the margins was arbitrarly defined as 1 cm around the MRI defined target volume (tumor of the cervix and its extension, and uterus). Results: In the first group (11 patients), MRI in treatment position led to a change in 7 patients: six inadequate margins in the lateral fields and one in the anterior and lateral field. In almost all the cases, the adjustments were of an increase of 10 mm, equally matched between the anterior and posterior borders of the lateral fields. In the second group (seven patients), MRI in treatment position has led to a change in lateral fields in five patients. The mean adjustment was 10 mm: four increases (two anterior border, one posterior border, one anterior and posterior border), and one decrease of the posterior border. In the two groups, modifications of the anterior border of the lateral

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.

Spectrum of rectal radiation lesions in cases of cancer cervix

Srivastava, V.K.; Rohatgi, V.K.; Gupta, J.C.

1978-01-01

The study was carried out in 70 cases of carcinoma cervix uteri, showing varying degree of proctitis following radiotherapy treatment for cervical cancer. Grossly, the rectal mucosa showed oedema, congestion, granular proctitis, ulceration, and microscopically stromal connective tissue as well as epithelial changes. The stromal changes have been emphasised as useful diagnostic criteria of radiation reaction. The familarity of these changes is considered necessary because it is imperative to know categorically that a given lesion is entirely or in part due to radiation or due to extension of adjacent tumour in the cervix. Further, this issue is very important in management of cases of cancer cervix. The criteria of distinguishing the lesions in the rectal tissue have been laid down. (auth.)

PURPOSE: Although cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) are both caused by human papillomavirus (HPV) infection, they differ in cofactors such as cigarette smoking. We assessed whether these cofactor differences translate into differences in second cancer risk. PATIENTS...... AND METHODS: We assessed second cancer risk among 85,109 cervical SCC and 10,280 AC survivors reported to population-based cancer registries in Denmark, Finland, Norway, Sweden, and the United States. Risks compared to the general population were assessed using standardized incidence ratios (SIR). RESULTS......: Overall cancer risk was significantly increased among both cervical SCC survivors (n = 10,559 second cancers; SIR, 1.31; 95% CI, 1.29 to 1.34) and AC survivors (n = 920 second cancers; SIR, 1.29; 95% CI, 1.22 to 1.38). Risks of HPV-related and radiation-related cancers were increased to a similar extent...

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.

Survival data, prognostic factors, and patterns of failure were retrospectively analyzed for a total of 76 patients with adenocarcinoma of the uterine cervix treated between January 1981 and December 1987, which represents 4.1% of all primary cervical carcinomas treated, at Department of Radiation Oncology, Yensei Cancer Center, Yonsei University College of Medicine. The mean age of the patients was 49years(range, 27-79years) and the peak incidence was in the group 50 to 59years of age. More half of the patients were postmenopausal (46/76=60.5%). Most patients(76%)had abnormal vaginal bleeding either alone or in combination with other symptoms. The proportion of stage Iib was 43.4%. There were 4 major histologic subtypes: pure adenocarcinoma(48/76=63.2%), adenosquamous carcinoma(20/76=26.3%), papillary (5/76=6.6%) and clear cell carcinoma(3/76=3.9%). Of the many clinicopathologic variables evaluated for prognosis, the most significant prognostic factors were stage of disease and the size of tumor. The overall 5-year survival rate was 68%, and the 5-year survival rates for stage Ib, II and III were 90%, 66% and 54%, respectively. Control of pelvic tumors was achieved in 938%, 90.2% and 50.0% of cases of stage Ib, II and III disease, respectively. In present study, treatment modalities (radiation therapy alone/combined operative and radiation therapy) did not affect the local control of tumor and the survival

Purpose: To compare patient demographics, treatment resources, practice patterns, and outcome results for squamous cell carcinoma of the uterine cervix (SCC) between the 1978 and 1983 Patterns of Care studies (PCS) in the United States of America (USA) and a nonacademic center within a developing country. Methods and Materials: Patient details (race, age, stage, and number per year), treatment used, and treatment outcome were retrieved from the charts of the 1160 cases registered at this center with SCC of the cervix between 1976 and 1985. Demographic variables and Kaplan-Meier survival estimates were calculated and compared with results from published PCS reviews. Results: There is a significant difference in the racial group presentation of cervix cancer at this center compared with the PCS reviews (p < 0.005), and median ages are significantly lower at this center (t = p < 0.001). The proportion of patients with Stage III or more was significantly higher at this center than the PCS centers (24 vs. 47%, p < 0.001). There were also vast differences in facility resources. Fewer cases at this center underwent intracavitary insertions than at PCS centers. Mean Point A doses were significantly reduced for this center compared with the PCS reviews. Kaplan-Meier estimates were similar for Stage I and II in PCS centers and this center, but were inferior for this center in Stage III patients (p < 0.05 for OS and p < 0.01 for LC). Late morbidity rates were similar for both PCS centers and this center. Conclusion: PCS recommendations may be applicable to nonacademic centers within developing countries, if the latter use staging techniques that are consistent with the PCS staging guidelines

1983-01-01

Rectal injury is one of the major side effects after radiation therapy for carcinoma of the uterine cervix. According to our previous reports, the cases of rectal complication were mainly related to the measured rectal dose in half of patients, and the other causes were related to the following factors; such as diabetes mellitus, hemorrhagic tendency, syphilis and so on. Concerning to rectal complication, these factors were investigated by means of the discriminant analysis, one of the multivariate analyses, in this paper. Twenty-eight factors as to radiation dose, laboratory tests and physical condition of patients were analyzed. From August 1978 through January 1980, 52 cases of previously untreated carcinoma of the uterine cervix were treated using RALS, remotely controlled high dose rate intracavitary radiotherapy, at our department. The data from 49 out of 52 cases were available for the discriminant analysis. By m eans of this analysis, it was found that these factors, such as the dose of whole pelvic irradiation, Point A dose of RALS, measured rectal dose by RALS, WGC-Z and TPHA were important factors for occurence of rectal complication. According to the discriminant score, 46 out of 49 cases (94 %) could be correctly discriminated. There were two cases of false positive and one false negative. Form February 1980 through July 1980, 27 cases of previously untreated carcinoma of the uterine cervix were treated at our department. The obtained discriminant function was applied to these 27 cases, and 24 out of 27 cases (89 %) were correctly predicted. There were two cases of false positive, and one of false negative. Discriminant analysis is useful for the prediction of rectal complication after radiation therapy for carcinoma of the uterine cervix. (J.P.N.)

2000-01-01

Purpose: To evaluate perioperative and postoperative complications of low-dose-rate (LDR) intracavitary radiation therapy in patients with FIGO Stage I-III carcinoma of the uterine cervix. Methods and Materials: We retrospectively reviewed the medical and radiotherapy records of all patients treated with radiation between 1960 and 1992 at The University of Texas M. D. Anderson Cancer Center for FIGO I-III carcinomas of the cervix. Patients who had had initial hysterectomy or whose treatment did not include intracavitary irradiation were excluded. The final study included 4043 patients who had undergone 7662 intracavitary procedures. Results: Eleven (0.3%) patients had documented or suspected cases of thromboembolism resulting in 4 deaths. Of these 11 patients, 8 had clinical or radiographic evidence of tumor involving pelvic nodes or fixed pelvic wall. The risk of postoperative thromboembolism did not decrease significantly with the routine use of mini-dose heparin prophylaxis (p = 0.3). Other life-threatening perioperative complications included myocardial infarction (1 death in 5 patients), cerebrovascular accident (2 patients), congestive heart failure or atrial fibrillation (3 patients), and halothane liver toxicity (2 deaths in 2 patients). Intraoperative complications included uterine perforation (2.8%) and vaginal laceration (0.3%), which occurred more frequently in patients ≥ 60 years old (p < 0.01). Fourteen percent of patients had a temperature ≥ 101 deg. F during at least one hospital stay. The only correlation between minor intraoperative complications and disease-specific survival was found in patients who had Stage III disease and uterine perforation; survival was significantly (p = 0.01) decreased in these patients. Conclusions: Fatal or life-threatening complications of intracavitary treatment were very rare. Deep venous thrombosis (DVT) and pulmonary embolism (PE) did not occur in otherwise healthy patients with early disease and were rare even

Purpose : To analyze survival rate and late rectal and bladder complication for patients with stage with stage I and II carcinoma of uterine cervix treated by radiation alone or combined with chemotherapy. Materials and Methods : Between November 1984 and December 1993, 127 patients with stage I and II carcinoma of uterine cervix treated by radiation alone or combined therapy of radiation and chemotherapy. Retrospective analysis for survival rate was carried out on eligible 107 patients and review for complication was possible in 91 patients. The median follow-up was 47 months (range 3-118) and the median age of patients was 56 years (range 31-76). 26 patients were stage IB by FIGO classification. 40 were stage IIA and 41 were stage IIB. 86 cases were treated by radiation alone and 21 were treated by radiation and chemotherapy. 101 patients were treated with intracavitary radiation therapy (ICRT), of these, 80 were received low dose rate (LDR) ICRT and 21 were received high dose rate (HDR) ICRT. Of the patients who received LDR ICRT, 63 were treated by 1 intracavitary insertion and 17 were underwent 2 insertions. And we evaluated the external radiation dose and midline shield. Results : Acturial survival rate at 5 years was 92% for stage IB, 75% for stage IIA, 53% for stage IIB and 69% in all patients. Grade 1 rectal complications were developed in 20 cases(22%), grade 2 were in 22 cases (24%), 22 cases (24%) of grade 1 urinary complications and 17 cases (19%) of grade 2 urinary complications were observed But no patients had severe complications that needed surgical management or admission care. Maximum bladder dose for the group of patients with urinary complications was higher than that for the patients without urinary complications(7608cGy v 6960cGy, p<0.01). Maximum rectal dose for the group of patients with rectal complications was higher than that for the patients without urinary complications (7041cGy v 6269cGy, p<0.01).

Since a majority of old aged patients have the troublesome complications and their physical or mental emaciation is clearly appeared, it is necessary for them to adopt a new treatment method which was considered about thier such conditions. The crude survival rate of old aged, over 71, patients suffered from carcinoma of the uterine cervix were 63.6% (7/11) for stage 1, 60% (36/60) for stage 2, 50% (53/106) for stage 3 and 28.6% (8/28) for stage 4. About 20% of patients in each stages were suffered from the complications. We considered the treatment method for the old aged patients such as follows: the radiation dose must be reduced 10% for 71 to 75 year old and 20% for 76 to 80 year old. In the case of over 81 year old, an intracavitary irradiation is only applied for the palliative aim at the out patient clinic. (author)

Thyroid Gland Metastasis from Cancer of the Uterine Cervix: An Extremely Rare Case Report.

Science.gov (United States)

Celik, Suleyman Utku; Besli, Dilara; Sak, Serpil Dizbay; Genc, Volkan

The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

Hyperfractionated radiotherapy of carcinoma of the uterine cervix and predictivity of empirical models

Carcinoma of the uterine cervix is the most common malignancy of women in India. Most of the patients attend for treatment at an advanced stage of the disease. The conventional fractionation schedule fails to give satisfactory tumour control rate in advanced malignancies. Twice daily fractionated radiotherapy (RT) with 1.2 Gy/F, 1.4 Gy/F and 1.6 Gy/F was tried in 40 cases each. The six months minimum follow-up shows that tumour control with 1.2 Gy/F twice daily (85.7%) is comparable with that of a conventional fractionation schedule (82.8%), whereas it is poor with 1.4 Gy/F (71.05%) and 1.6 Gy/F (68.0%) schedules. Attempts were made to apply time dose fractionation (TDF) and linear quadratic (LQ) models to observed tumour control rates. It was observed that time dose fractionation fails to correlate with the observed tumour control rate (p > 0.2). The extrapolated response dose (ERD) analysis also fails to correlate with the tumour control rate (p > 0.3). (author). 29 refs., 4 tabs

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)

A prospective randomized study in selected patients with Stage IB and IIA carcinoma of the uterine cervix was carried out. Patients were randomized to be treated with 1) irradiation alone consisting of 1000 rad whole pelvis, additional 4000 rads to the parametria with a step wedge midline block, and two intracavitary insertions for 7500 mgh; and 2) irradiation and surgery, consisting of 2000 rad whole pelvis irradiation, one intracavitary insertion for 5000 to 6000 mgh followed in two to six weeks later by a radical hysterectomy with pelvic lymphadenectomy. The five-year, tumor-free actuarial survival for Stage IB patients treated with radiation was 87% and with preoperative radiation and surgery 82%. In Stage IIA, the actuarial five-year survival NED was 57% for the irradiation alone group and 71% for the patients treated with preoperative radiation and radical hysterectomy. Major complications of therapy were slightly higher in the patients trated with radiation alone (9.4%, consisting of one recto-vaginal fistula and one vesico-vaginal fistula and a combined recto-vesico-vaginal fistula in another patient). In the preoperative radiation group, only two ureteral strictures (4.1%) were noted. The present study shows no significant difference in therapeutic results or morbidity for invasive carcinoma of the uterine cervix Stage IB or IIA treated with irradiation alone or combined with a radical hysterectomy

Remodeling of the cervix occurs in advance of labor both at term and at preterm birth. Morphological characteristics associated with remodeling in rodents were assessed in cervix biopsies from women at term (39 weeks' gestation) and preterm (cervix biopsies from women in labor at term and preterm compared to that in the cervix from nonlaboring women. Extracellular collagen was more degraded in sections of cervix from women at term, based on optical density of picrosirius red stain, versus that in biopsies from nonpregnant women. However, collagen structure was unchanged in the cervix from women at preterm labor versus the nonpregnant group. As an indication of inflammation, cell nuclei density was decreased in cervix biopsies from pregnant women irrespective of labor compared to the nonpregnant group. Moreover, CD68-stained macrophages increased to an equivalent extent in cervix subepithelium and stroma from groups in labor, both at term and preterm, as well as in women not in labor at term. Evidence for a similar inflammatory process in the remodeled cervix of women at term and preterm birth parallels results in rodent models. Thus, a conserved final common mechanism involving macrophages and inflammation may characterize the transition to a ripe cervix before birth at term and in advance of premature birth. © The Author(s) 2015.

Premature cervical remodeling resulting in spontaneous preterm birth may begin with premature failure or relaxation at the internal os (termed "funneling"). To date, we do not understand why the internal os fails or why funneling occurs in some cases of premature cervical remodeling. Although the human cervix is thought to be mostly collagen with minimal cellular content, cervical smooth muscle cells are present in the cervix and can cause cervical tissue contractility. To understand why the internal os relaxes or why funneling occurs in some cases of premature cervical remodeling, we sought to evaluate cervical smooth muscle cell content and distribution throughout human cervix and correlate if cervical smooth muscle organization influences regional cervical tissue contractility. Using institutional review board-approved protocols, nonpregnant women cervix, whole cervical slices were obtained from the internal os, midcervix, and external os and immunostained with smooth muscle actin. To correlate tissue structure with function, whole slices from the internal and external os were stimulated to contract with 1 μmol/L of oxytocin in organ baths. In separate samples, we tested if the cervix responds to a common tocolytic, nifedipine. Cervical slices from the internal os were treated with oxytocin alone or oxytocin + increasing doses of nifedipine to generate a dose response and half maximal inhibitory concentration. Student t test was used where appropriate. Cervical tissue was collected from 41 women. Immunohistochemistry showed cervical smooth muscle cells at the internal and external os expressed mature smooth muscle cell markers and contraction-associated proteins. The cervix exhibited a gradient of cervical smooth muscle cells. The area of the internal os contained 50-60% cervical smooth muscle cells that were circumferentially organized in the periphery of the stroma, which may resemble a sphincter-like pattern. The external os contained approximately 10

The aim of this prospective study was to assess the usefulness of 18 F-FDG PET/CT performed before and during treatment for predicting treatment failure in patients with advanced squamous cell carcinoma of the uterine cervix treated with concurrent chemoradiotherapy (CCRT). Patients with cervical squamous cell carcinoma, International Federation of Gynecology and Obstetrics stage III/IVA or positive pelvic or paraaortic lymph node (LN) metastasis without other distant metastasis on PET/CT entering a randomized trial of CCRT (AGOG 09-001) were eligible. PET/CT scans were performed at baseline, during week 3 of CCRT and 2 - 3 months after CCRT. PET/CT parameters were correlated with sites of failure and overall survival (OS). The resulting predictors developed from the study cohort were validated on two independent datasets using area under the curve values, sensitivities and specificities. With a median follow-up of 54 months for survivors, 20 (36 %) of the 55 eligible patients were proven to have treatment failure. Sites of failure were local in five, regional in 11, and distant in 11. Four predictors for local failure, three for regional failure, and four for distant failures were identified. After validation with two independent cohorts of 31 and 105 patients, we consider the following as clinically useful predictors: pretreatment metabolic tumour volume (MTV) and during-treatment cervical tumour MTV for local failure; during-treatment SUVnode (maximum standardized uptake value of LNs) for regional and distant failure, and during-treatment MTV for distant failure. During-treatment SUVnode (P =.001) and cervical tumour MTVratio (P =.004) were independent significant predictors of OS by stepwise Cox regression. PET/CT imaging before and during treatment is useful for predicting failure sites and OS, making tailored therapeutic modifications feasible with potential outcome improvement during primary therapy.

Collision tumor is an extremely rare tumor which defined as the concrescence of two distinct primaries neoplasms. We report here a case of collision tumor at lower third esophagus composed of small cell type neuroendocrine carcinoma (NEC), which is an very rare, highly aggressive and poorly prognostic carcinoma and squamous cell carcinoma (SqCC). In our case, pathologically, the small cell carcinoma display the characteristic of small, round, ovoid or spindle-shaped tumor cells with scant cytoplasm, which colliding with a moderately differentiated squamous cell carcinoma. Immunohistochemical staining demonstrated positive activities for CD56, synaptophysin, 34βE12, CK 5/6, ki-67 (70%-80%), but negative for CD99, chromogranin A, and TTF-1. Accurate diagnosis was made base on these findings. PMID:24817981

Carcinoma of uterine cervix is one of the most common diseases among the women in India where radiotherapy is the mainstay of treatment. Most common practice of dose prescription point is the Manchester Point A. American Brachytherapy Society (ABS) recommends a point H equivalent to that used in the classical Manchester system. Many centre practices Madison point M as dose specification point which is 20 mm cephaled along the tandem from a line joining the mid dwell positions in the ovoids/ring and 20 mm lateral to the tandem. In the present study has compared the dose prescription points between Manchester Point A and Madison Point M for ring applicators and their implication in the assessment of rectal and bladder doses in patients of Carcinoma of uterine cervix

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

The serum levels of SCC antigen (squamous cell carcinoma related antigen) were measured in 111 patients with primary lung cancer to assess its clinical usefulness for diagnosis of squamous cell carcinoma and for monitoring recurrence and effectiveness of therapies. Serum SCC antigen level in patients with squamous cell carcinoma of the lung was 5.9 ± 10.4 ng/ml, which was high (p < 0.05) compared with those in normal controls (1.6 ± 0.5 ng/ml), patients with other types of lung cancer (2.4 ± 2.9 ng/ml) or benign disease (1.8 ± 1.1 ng/ml). Studies at various clinical stages of squamous cell carcinoma of the lung showed, however, that the SCC antigen levels were high only in the advanced stages (III and IV), whereas not so high in the earlier stages. These results confirmed that SCC antigen is a relatively specific marker to squamous cell carcinoma in the lung, as reported in the uterine cervix and the esophagus. The SCC antigen levels decreased after operation and more markedly after radiotherapy in dose-dependent manner, corresponding to the reduction of the tumor size. On the other hand, the SCC antigen levels were extremely high in the recurrence. It was concluded that SCC antigen is a useful marker for monitoring recurrence or effectiveness of the therapies of SCC of the lung, although not so for its early diagnosis. (author)

To evaluate the pathologic response of cervical carcinoma to external beam radiotherapy (EBRT) and high dose rate brachytherapy (HDRB) and outcome. Between 1992 and 2001, 67 patients with cervical carcinoma were submitted to preoperative radiotherapy. Sixty-five patients were stage IIb. Preoperative treatment included 45 Gy EBRT and 12 Gy HDRB. Patients were submitted to surgery after a mean time of 82 days. Lymphadenectomy was performed in 81% of patients. Eleven patients with residual cervix residual disease on pathological specimen were submitted to 2 additional insertions of HDRB. median follow up was 72 months. Five-year cause specific survival was 75%, overall survival 65%, local control 95%. Complete pelvic pathological response was seen in 40%. Surgery performed later than 80 days was associated with pathological response. Pelvic nodal involvement was found in 12%. Complete pelvic pathological response and negative lymphnodes were associated with better outcome (p = .03 and p = .005). Late grade 3 and 4 urinary and intestinal adverse effects were seen in 12 and 2% of patients. Time allowed between RT and surgery correlated with pathological response. Pelvic pathological response was associated with improved outcome. Postoperative additional HDRB did not improve therapeutic results. Treatment was well tolerated

Purpose: The Patterns of Care Study (PCS) of patients treated in 1988-89 included 'patterns of treatment planning' for radiotherapy of carcinoma of the uterine cervix. A Consensus Committee of radiation physicists and oncologists established current guidelines and developed questionnaires to assess the treatment planning process (i.e., the general structure, methodology, and tools) of institutions involved in the Patterns of Care Study. This paper reports the findings of the assessment. Methods and Materials: The PCS surveyed 73 radiotherapy facilities, of which 21 are academic institutions (AC), 26 hospital-based facilities (HB), and 26 free-standing centers (FS). In total, 242 cases were assessed with 39% from academic centers, 33% from hospital-based centers, and 28% from free-standing centers. The survey collected treatment planning information such as the use of computed tomography (CT), simulation procedure, contouring of patient outline, tumor or target delineation, identification of critical structures, method of dose prescription (point or isodose), etc. Data was also obtained concerning implant boosts, e.g., radioisotope used, use of midline block for external beam treatment, availability of remote afterloader, practice of interstitial implants, combination with hyperthermia, etc. Results: There is a high degree of compliance relative to the basic treatment planning standards. For example, 171 cases (out of 173) from AC and HB institutions included simulation and 169 used port film; for cases from FS centers, 61 out of 69 involved simulation and 66 out of 69 included port film. Most institutions used linacs (231 out of 242); in five cases, Co-60 units and in six cases betatron was used. In terms of treatment planning, 53% used skin contours, but only 14% had target volume delineation, with AC and HB being slightly more conscientious in these efforts. Critical organs did not appear to be explicitly considered in external beam treatment planning, with only

Purpose: The aim of this work is to investigate an unusually high rate of late rectal complications in a group of 43 patients treated with concomitant irradiation and chemotherapy for carcinoma of the cervix between December 1988 and April 1991, with a view to identifying predictive factors. Methods and Materials: The biologically effective dose received by each patient to the rectal reference point defined by the International Commission of Radiation Units and Measurements, Report 38, were calculated. Radiotherapy consisted of 46 Gy external beam irradiation plus three high dose-rate intracavitary treatments of 10 Gy each prescribed to point A. Cisplatin 30 mg/m 2 was given weekly throughout the duration of the irradiation. The results have been compared to data from 119 patients treated with irradiation alone to assess the confounding effect of the cisplatin. Results: The relationship between the biologically effective dose delivered to the rectal reference point and the development of late complications shows a strong dose-response with a threshold for complications occurring at approximately 125 Gy 3 corresponding to a brachytherapy dose of approximately 8 Gy per fraction. This value is approximately the same biologically effective dose threshold as that found for external beam irradiation in the head and neck region. The data from the group of patients treated without cisplatin is comparable to the data from the first group of patients in the lower dose ranges; the higher doses were not used and thus are not available for comparison. Conclusion: Using the linear quadratic model applied to our clinical results, we have established a threshold for late rectal complications for patients treated with external beam irradiation and high dose-rate brachytherapy for carcinoma of the cervix. This threshold is consistent with similar data for external beam irradiation in the head and neck region

As the traditional risk factors for oral squamous cell carcinoma, especially tobacco, decline, new potential causative agents become the focus of research. Since the discovery of human papillomavirus (HPV) and its importance in carcinogenesis in cervical cancer, a lot of research has been undertaken to define its role in different types of cancer. In the present study, we evaluate the role of high-risk HPV types in initiation and progression of oral squamous cell carcinoma (OSCC) using a systematic review of the current literature. A literature research with the search term "HPV oral squamous cell carcinoma" was performed via PubMed. Results were screened systematically for relevance and classified into the following categories: molecular biology, genetics, clinical aspects, and prevalence. Articles were then further analyzed to assess quality. The literature research led to 527 results, with an overall HPV prevalence of 30.1 % in OSCCs. The most frequently identified subtypes were HPV-16 and HPV-18 (25.4 and 18.1 %, respectively). Prognostic relevance of HPV was discussed controversially. HPV detection via polymerase chain reaction is the most established method today. Molecular changes according to carcinogenic pathways described for cervix carcinoma were not routinely found in OSCC. In general, no definite role of high-risk HPV is currently deducible from the literature. High-risk subtypes 16 and 18 are present in the genome in approximately one third of OSCC. Its role as a causative agent is less clear than the role in oropharyngeal tumors. The infection might not be the cause of carcinogenesis in a significant number of patients but may become proportionally more important with the decrease of the classical risk factors of tobacco and alcohol.

We studied nine cases of endometrial carcinoma and twenty of cervix carcinoma. Correlation with histology is made after curietherapy in 8 cases of endometrial carcinoma. Tumor is not always seen and particularly when there is no mass effect on macroscopic examination. Myometral invasion is not seen with accuracy: the interruption of junctional zone is not a good sign. The cervix tumors are well seen on T2 sequences before any treatment. There extra uterine extension is difficult to appreciate. The best results of RMI were in the follow-up after radiotherapy. Therefore it appears actually to us the best indication of RMI [fr

Prospective, single arm. Phase I/II clinical trial was performed to assess the efficacy and toxicity of the concurrent chemotherapy and definitive radiotherapy (RT) in patients with previously untreated locally advanced carcinoma of the uterine cervix. From May 1992 to January 1997, a total of 73 patients with advanced cervical carcinoma were entered on the protocol but 5 patients were excluded in analysis because of patients' refusal of treatment. Their ages ranged from 31 to 77 years, median 58 years. The international Federation of Gynecology and Obstetrics (FIGO) stage distribution was as follows: IIB 46, IIIA 2, IIIB 15 and IVA 5. RT consisted of external beam irradiation to 4, 140-5, 040 cGy/23-28 fractions plus high dose rate intracavitary treatments to deliver a dose of 30-35 Gy to point A in 6-7 fractions. During the intracavitary treatments parametrial boost was delivered for point B dose of 60 Gy in stage IIB and 65 Gy in stage IIIB. Two cycles of concurrent 5-fluorouracil and cisplatin (FP) chemotherapy (5-fluorouracil 1,000 mg/m 2 /day continuous infusion for 4 days, day 1-4, 29-32 and cisplatin 20 mg/m 2 /dy intravenous bolus for 3 days, day 1-3, 29-31) administered starting on day 1 of 1 of RT. The median follow-up was 24 months (range 4-68+). Sixty-four patients were evaluable for survival rate in this protocol: The 5-year actuarial and disease-free survival rate were 52% and 64%, respectively. The 5-year actuarial survival for stage IIB and II+IVA patients were 58% and 36%, respectively. The 5-year disease-free survival rate for stage IIB and III+IVA patients were 71% and 46%, respectively. Of the 68 patients evaluated for patterns of failure, overall recurrence rate was 27.9% (19/68): local failure in 5.9% (4/68), distant metastasis in 10.3% (7/68) and both in 11.8% (8/68). Of the 64 patients evaluated for response at one month after the completion of treatment, the complete response rate was 78% (50/64). Concurrent chemoradiation appear to be a

Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

Full text: Hyperthermia treatment planning (HTP) is a useful tool for improvement of clinical hyperthermia treatments. Aim of this study was to determine the correlation between HTP and measurements during hyperthermia treatments. We compared the calculated specific absorption rate (SAR) with clinically measured SAR-values, from ΔT-measurements, in cervix carcinoma patients. General difficulties for such clinical verifications are changes in the anatomy during the different steps and possible movement of the catheters. We used one fixed invasive catheter in the tumor additional to the usual non-invasive catheters in the vagina, bladder and rectum, for insertion of multisensor thermocouple probes. A special CT-scan with the patient in treatment position and the catheters in situ was made for the HTP. We performed these verifications in a total of 11 treatments in 7 patients. The main difficulties for accurate verification were of clinical nature: difficulties arising from the use of gynaecological tampon and the limited number of measurements in tissue. Remaining air in the vagina and sub-optimal tissue contact of the catheters resulted in bad thermal contact between thermocouples and tissue, causing measurement artefacts that are difficult to correlate with calculations. These artefacts are probably not specific for thermocouple measurements, but more general for intraluminal temperature and SAR measurements. (author)

In whole pelvis irradiation using the conformation technique for the patient with carcinoma of the uterine cervix, standardization of the shape of the treated region was tried on the basis of measuring the pelvis in X-ray films. This was done on the X-rays of 200 patients with carcinoma of the uterine cervix. The body-type of the patient the most remarkably influenced the shape of the treated region. Ten clinical types of cam-group (treated region) were determined, in order to perform conformation radiotherapy for carcinoma of the uterine cervix. Although the shape of the treated region could also be changed by the invasion of the lesion, the position of the portio and the general condition of the patients, these 10 standard types of cam-group can be applied practically to almost all of the patients.

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. When an effective salvage treatment is developed in

This study evaluated the survival outcome, pattern of failure and prognostic factors in cervix uteri cancer patients. We reviewed the data of 60 patients with stages IB-IVA cancer who were treated between January 2004 and December 2010. Most patients (n = 50; 83%) had squamous cell carcinoma. Stage IIB was the most common presentation (n = 41; 68%). Forty-seven patients (78%) received Cisplatin concurrent with radiotherapy (CRT). The 2- and 4-year overall survival (OS) was 82% and 79%, respectively. Prolongation of the overall treatment time (OAT) for greater than 56 days, advanced stage and pretreatment hemoglobin (Hb) levels (cervix uteri cancer patients and the prognostic factors are comparable to those of previous reports.

Purpose: To evaluate whether pretreatment carcinoembryonic antigen (CEA) levels have a prognostic role in patients after definitive radiotherapy for squamous cell carcinoma (SCC) of the uterine cervix. Methods and Materials: A retrospective study of 550 patients was performed. The SCC antigen (SCC-Ag) and CEA levels were regarded as elevated when they were ≥2 and ≥5 ng/mL, respectively. A total of 208 patients underwent concurrent chemoradiotherapy (CCRT). The Kaplan-Meier method was used to calculate the distant metastasis (DM), local failure (LF), disease-free survival (DFS), and overall survival (OS) rates. Multivariate analysis was performed using the Cox proportional hazards model. The hazard ratio (HR) with 95% confidence interval (CI) was evaluated for the risk of a poor prognosis. Results: Compared with the patients with normal CEA/SCC-Ag levels, CEA levels ≥10 ng/mL but without elevated SCC-Ag levels was an independent factor for LF (HR, 51.81; 95% CI, 11.51–233.23; p < .001), DM (HR, 6.04; 95% CI, 1.58–23.01; p = .008), DFS (HR, 10.17; 95% CI, 3.18–32.56; p < .001), and OS (HR, 5.75; 95% CI, 1.82–18.18; p = .003) after RT alone. However, no significant role for CEA was noted in patients with SCC-Ag levels ≥2 ng/mL. In patients undergoing CCRT, a CEA level ≥10 ng/mL was an independent factor for LF (HR, 2.50; 95% CI, 1.01–6.21; p = .047), DM (HR, 3.41; 95% CI, 1.56–7.46; p = .002), DFS (HR, 2.73; 95% CI, 1.39–5.36; p = .003), and OS (HR, 3.93; 95% CI 1.99–7.75; p < .001). A SCC-Ag level of ≥40 ng/mL was another prognostic factor for DM, DFS, and OS in patients undergoing not only CCRT, but also RT alone. The 5-year OS rate for CCRT patients with CEA <10 ng/mL and ≥10 ng/mL was 75.3% and 35.8%, respectively (p < .001). CCRT was an independent factor for better OS (HR, 0.69; 95% CI, 0.50–0.97; p = .034). Conclusion: Pretreatment CEA levels in patients with SCC of the uterine cervix provide complementary information for

The frequency and degree of severity of radiation in unjuries of the urinary bladder and rectum after combined treatment of 725 patients with uterine cercix carcigoma are analysed. A quantitative index was worked out permi-- tting one to give an ob ective evaluation of the degree of early radiation reactions of the ad acent organs. The determination of the ''radiation injuries prognosis index'' (RIPI) makes it possible to forecast the occurence and degree of severity of late radiation injuries of the urinary bladder and rectum. The evaluation of RIPI mean values in the patients' groups provides an opportunity to oompare the damaging effect of different methods and regiment directly in the process of radiation therapy. The above method improves the potentialities of the forecasting of radiation injuries of the urinary bladder and rectum in patients with uterine cervix carcinoma

Full Text Available Abstract Background Pentacyclic triterpenes, mainly betulin and betulinic acid, are valuable anticancer agents found in the bark of birch tree. This study evaluates birch bark extracts for the active principles composition. Results New improved extraction methods were applied on the bark of Betula pendula in order to reach the maximum content in active principles. Extracts were analyzed by HPLC-MS, Raman, SERS and 13C NMR spectroscopy which revealed a very high yield of betulin (over 90%. Growth inhibiting effects were measured in vitro on four malignant human cell lines: A431 (skin epidermoid carcinoma, A2780 (ovarian carcinoma, HeLa (cervix adenocarcinoma and MCF7 (breast adenocarcinoma, by means of MTT assay. All of the prepared bark extracts exerted a pronounced antiproliferative effect against human cancer cell lines. In vivo studies involved the anti-inflammatory effect of birch extracts on TPA-induced model of inflammation in mice. Conclusions The research revealed the efficacy of the extraction procedures as well as the antiproliferative and anti-inflammatory effects of birch extracts.

Full Text Available Adenocarcinoma in situ is one of the premalignant lesions of the cervix and its incidence is believed to be increasing while the pathogenesis of the disease is not clearly understood. Management of Adenocarcinoma in situ (AIS unlike carcinoma in situ (CIS has not been clearly described in the current literature. Here we describe conservative management and serial colposcopy of two pregnant women with adenocarcinoma in situ of the cervix. Both of the cases were diagnosed initially with abnormal Pap smears and were confirmed by colposcopic directed biopsy. None of the patients agreed with any invasive procedure during pregnancy and both of them were followed with serial colposcopy. None of the lesions showed any evidence of progression. All cases underwent cold knife cone biopsies in their postpartum period. Hysterectomy as the final treatment has been done in both cases with no evidence of progression of the disease during pregnancy. We concluded that adenocarcinoma in situ of the cervix during pregnancy could be managed conservatively with definite treatment postponed till after delivery.

Full Text Available Abstract Background Cancer of the cervix is the second commonest malignancy in females worldwide and is the leading malignancy among women in Tanzania. Cancer of the cervix has been strongly associated with Human Papilloma Virus (HPV which is a sexually transmitted disease. However, the role of HIV-1 in the aetiology of cancer of the cervix is less clear. Studies suggest that HPV and HIV-1 infection are synergistic and therefore their dual occurrence may fuel increased incidence of cancer of the cervix and AIDS. We therefore conducted a study to determine the association between cancer of the cervix and HIV-1. Methods The study was carried out in Ocean Road Cancer Institute, Dar-es-salaam, Tanzania between January and March 2007. A hospital-based case control design was used to study 138 cases and 138 controls. The cases were consenting women 18 years and above with histologically confirmed squamous cell carcinoma of the cervix, while the controls were consenting non-cancer adult women attendants or visitors. The participants were counselled and tested for HIV-1 and interviewed to assess risk factors for cancer of the cervix and HIV-1. Estimation of risk was done by computing odds ratios and confidence intervals. Confounding and interaction between the factors were assessed using logistic regression. Results HIV-1 prevalence was much higher among the cases (21.0% than among the controls (11.6%. In logistic regression, HIV-1 was associated with cancer of the cervix (OR = 2.9, 95% CI = 1.4–5.9. Among the cases the mean age was lower for HIV-1 infected (44.3 years than HIV-1 uninfected women (54 years, p = 0.0001. Conclusion HIV-1 infection is associated with invasive cancer of the cervix. Resource-constrained countries with a high burden of HIV-1 and cervical cancer should adopt a high-risk approach that targets HIV-1 positive women for screening of cervical cancer initially by utilizing HIV/AIDS resources.

Full Text Available This paper works at segmentation of lesion observed in cervical cancer, which is the second most common cancer among women worldwide. The purpose of segmentation is to determine the location for a biopsy to be taken for diagnosis. Cervix cancer is a disease in which cancer cells are found in the tissues of the cervix. The acetowhite region is a major indicator of abnormality in the cervix image. This project addresses the problem of segmenting uterine cervix image into different regions. We analyze two algorithms namely Watershed, K-means clustering algorithm, Expectation Maximization (EM Image Segmentation algorithm. These segmentations methods are carried over for the colposcopic uterine cervix image.

Locally advanced cervix carcinoma - innovation in combined modality therapy

International Nuclear Information System (INIS)

Swift, Patrick S.

1996-01-01

Locally advanced cervical carcinoma continues to be a challenge to the clinician due to local failure as well as systemic metastases. Standard intracavitary and external beam techniques result in local control rates of only 35-65%, with long term survival rates of 25-60% in patients with state IIIA-IVA disease, indicating the need to identify new treatment strategies. Optimization programs for remote-afterloading interstitial brachytherapy allow the delivery of higher local doses of radiation to volumes that more closely approximate tumor target volumes as identified on MR scans, leading to improved therapeutic ratios. Identification of subsets of patients more likely to fail standard therapy, either locally or systemically, may be possible through such techniques as in vivo measurements of hypoxia with Eppendorf oxygen electrodes, interstitial fluid pressure measurements, the Comet assay, and nitroimidazole binding methods. Traditional chemotherapies, administered in either a neoadjuvant role or concomitantly with radiation have been disappointing in prospective trials. A variety of new agents are being investigated to determine if they can increase the frequency or duration of complete response. The taxanes, with response rates of 17-23% by themselves, are being assessed as potential radiosensitizers. The camptotheicin CRT-11 (Irinotecan) has demonstrated activity in platinum resistant cervix cancer, with response rates of 24%. Bioradiotherapeutic approaches, using 13-cis-retinoic acid and interferon-2a, are undergoing phase II studies. Neoangiogenesis inhibitors and vaccines against HPV are also being examined. The aggressive pursuit of techniques that help identify those patients most likely to fail, that allow the delivery of higher radiation doses more safely to the target volume, and that incorporate the use of more effective systemic therapies is necessary to improve the outcome for this disease

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

To ensure accurate dose delivery to target site in external beam therapy and brachytherapy, various authors have conducted tests to assess the process of manual dose calculations. In vivo dosimetric measurement is one of these methods to verify these calculations. In this study, an attempt has been made to compare the manually calculated dose to dose estimated using a chemical dosimeter (FBX) solution (in-vivo method, using polypropylene vials), on 12 patients of carcinoma of uterine cervix in external beam therapy. Dose measured by FBX vial varies in the range of ± 2 to 6.75%, as compared with manual calculations. These variations seen may be attributed to the location of the vial position in the vagina, with reference to the beam axis (may not be horizontal), off axis position, manual calculation variations and reproducibility of the FBX system etc. FBX dosimetry offers itself as an in-vivo method to estimate the dose delivered to the target site in external beam therapy.

Kim, Mi Sook; Ha, Sung Whan

1992-01-01

From March 1979 through December 1986, 124 patients with early stage carcinoma of the uterine cervix received curative radiation therapy. According to FIGO classification, 35 patients were stage IB and 89 were stage IIA. In stage IB, five year locoregional control, five year disease A, five year locoregional control, five disease free survival, and five year overall survival were 78.0%, 66.8%, and 72.1%, respectively. To identify prognostic factor, pretreatment including age, ECOG performance status, number of pregnancies, history of diabetes mellitus and hypertension, histology, size and shape of primary tumor, CT findings and blood parameters were retrospectively analyzed in terms of locoregional control, disease free survival and overall survival using univariate analysis and multivariate analysis. In univariate analysis, tumor size on physical examination and rectal invasion on CT significantly affected locoregional control, disease free survival and overal survival. Parametrial involvement on CT was a significant prognostic factor on locoregional control and disease free survival. Hemoglobin level affected disease free survival and overall survival. Histology and age were significant pronostic factor on locoregional control. In multivariate analysis excluding CT finding, tumor size on physical examination was a significant factor in terms of locoregional control and overall survival. Hemoglobin level was significant in terms of disease free survival. In multivarate analysis including CT, histology was a prognostic factor on locoregional control and disease free survival. Hemoglobin level and rectal invasion on CT were significant factors on locoregional control

Purpose/Objective: To determine the efficacy of Mitomycin C (MC) in combination with radiotherapy (RT) for the treatment of carcinoma of the cervix Materials and Methods: A Phase III randomized study of MC + RT (CMT) vs. RT was initiated in 1990 to test whether or not a bioreductive alkylating agent would improve the cure of squamous cell carcinoma of the cervix (CCa), a tumor for which hypoxia is known to be a strong prognostic factor. As of March 1996, 157 patients have been enrolled. After excluding 8 patients (pts) for protocol violations (3 in CMT group and 5 in RT group), the 110 analyzable pts having at least two years of partial follow-up were used for the preliminary analysis reported here. Intravenous MC, 15 mg/M 2 , was given on the 1st and 6th week of treatment. Before randomization between CMT and RT, patients were stratified by standardized radiotherapy prescriptions of both brachytherapy and external beam RT dose, as dictated by tumor stage. Results: The 58 pts in the CMT group and 52 pts in the RT group have a mean follow-up of 27.1 months, and a comparable distribution by age and stage (mean age 48.3 years; stage IB 2%, IIA 14%, IIB 47%, IIIA 1%, IIIB 34%, IVA 3%). The three year actuarial survival rates for CMT and RT were 77% and 58%, respectively (p=0.15). Three months following completion of therapy, complete response (CR) was achieved in 51 pts (88%) of the CMT group and in 47 pts (90%) of the RT group (p=NS). Of those with CR, the three year actuarial local recurrence free survivals for CMT and RT were 84% and 68%, respectively (p=0.12). There were no treatment-related deaths. Mild hematologic toxicity was seen only in the CMT group, with 4 pts having a nadir WBC <1.5 (but none below 1.0) and with 1 pt having a nadir platelet count below 25K. Grade 3 skin toxicity was seen in 3 pts receiving CMT and 1 pt receiving RT alone. Grade 3 cystitis was seen in one RT pt. Grade 3 and 4 GI toxicities were seen in two RT pts. No excess in non

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)

Purpose: Retrospective studies have suggested that overall treatment time is an important determinant of outcome for locally advanced squamous carcinoma of the cervix managed with definitive radiotherapy. We initiated a prospective clinical trial to test the hypothesis that minimizing treatment time can prevent tumor cell repopulation in squamous cell carcinoma of the cervix. Materials and Methods: Between 1989 and 1994 twenty two patients with FIGO stage IIIA to IVA squamous cell carcinoma of the cervix were treated as follows: Forty-five Gy was delivered to the whole pelvis in 25 fractions in 5 weeks using photon energies of 6 MV or greater. On Monday, Wednesday, and Friday of each of the last three weeks of treatment, a boost treatment of 1.6 Gy was given via small lateral parallel opposed fields, six hours after the first fraction. Thus, the total dose to the tumor and parametrial region was 59.4 Gy. A single brachytherapy procedure (Standard Tandem and Ovoids or Interstitial Template) was performed one week after the completion of external beam radiotherapy to bring the point A dose to 90 Gy in 6 weeks. Results: With a median follow-up of 30 months, (range: 5 to 42 months) the actuarial 3 year overall survival is 61.5% and the disease-free survival is 51.4%. Two out of twenty two patients (9.1%) had loco-regional failure alone, (5(22)) (22.7%) had distant failure only, and (4(22)) (18.2%) had both. The actuarial loco-regional control at 3 years is 69.5% with a distant metastasis-free survival of 57.5%. The median length of treatment was 46 days with a range of 35 to 107 days Most of the patients had only mild acute reactions, mainly diarrhea. There were no severe acute reactions. Thirteen of 22 patients (59.1%) had no late complications. Three patients had chronic proctitis, one with intermittent bleeding. Six (27.3%) patients experienced severe late complications consisting of vesico-vaginal fistulas, recto-vaginal fistulas and small bowel obstruction. One

2006-01-01

Background and purpose: A subset of patients in a clinical study where sequential biopsies were to be obtained during multifraction radiotherapy received pimonidazole prior to initiating treatment, allowing a unique opportunity of following hypoxic cells in situ during therapy. Material and methods: After institutional ethics review and with informed consent, women expecting to undergo radical treatment for cancer of the cervix received pimonidazole hydrochloride, with a biopsy approximately 24 h later. Therapy was then started, and weekly biopsies were obtained. In the laboratory, the biopsies were reduced to single cell suspensions for flow cytometry analysis of DNA content, pimonidazole, and proliferation markers. Results: Pre-treatment pimonidazole-positive cells were largely in G /G 1 . Pimonidazole-labelled cells, though expected to be radioresistant, were markedly decreased even early into treatment, and continued to disappear with a half-time of about 3 days. Concurrently, the cell cycle distribution of the previously hypoxic cells changed from predominantly quiescent to mostly proliferating. Conclusions: While a part of the rapid apparent loss of hypoxic cells was certainly due to loss of pimonidazole adducts through repair and dilution by cell division, the speed with which this occurred suggests that many labelled cells could rapidly re-enter the proliferative pool, a result consistent with many of those pimonidazole-labelled human cervix tumour cells being cyclically, rather than continuously, hypoxic

The purpose of this study is to report an unusual variant of cervical squamous cell carcinoma, not associated with either human papillomavirus infection or antecedent squamous intraepithelial lesions. Five women had a diagnosis of invasive cervical cancer discovered at hysterectomy performed for prolapse (two cases), leiomyoma (one case), or a vaginal fistula (two cases). The women ranged in age from 47 to 78 years (mean 59 years). Four of the five had a history of normal Papanicolaou (Pap) smears; the other had a Pap smear diagnosis of atypical squamous cells of undetermined significance (ASCUS). All had large cervical tumors (two with parametrial involvement and one with vaginal involvement) that showed extensive keratin formation, an inverted pattern of growth, and, except for one case, minimal cytologic atypia. There was extensive hyperkeratosis and parakeratosis adjacent to each tumor; none had evidence of squamous intraepithelial lesion. Human papillomavirus testing by polymerase chain reaction in situ hybridization and reverse-transcribed polymerase chain reaction in situ was negative in each case, compared with a detection rate of 107 of 108 (99%) for squamous intraepithelial lesion-associated cervical squamous cell and adenocarcinomas. Two of the women died of extensive local recurrence; two other women were recently diagnosed. We conclude that highly differentiated keratinizing squamous cell carcinoma of the cervix is a rare entity not associated with human papillomavirus infection or squamous intraepithelial lesion and thus difficult to detect on routine cervical cancer screening.

Purpose : Radiation therapy(RT) is conventionally standard treatment for locally advanced stage for uterine cervix cancer. Recently to improve treatment results, combined chemotherapy and radiation therapy was tried. We retrospectively analysed our experience of 122 patients. Comparison of the results in 45 patients treated with RT alone and 77 patients treated with RT plus chemotherapy was made. Materials and Methods : from January 1985 to December 1991, 122 patients with cervix cancer were treated with whole pelvic external RT and ICR(34 1 ICR, 77 2 ICR, 11 high dose rate ICR) in our department. Forty five patients were treated with RT alone, and 77 patients were treated with combined plus chemotherapy. Mean age was 58 years(range:29-81). Histologic types were 111 squamous cell carcinoma, large cell carcinoma, 3 adenocarcinoma, and 2 adenosquamous cell carcinoma. According to the FIGO stage 6 had stage IA94.9%, 11 had IIA(9.0%), 37 had IIB(30.3%), 3 had IIA(2.5%), 63 had IIB(51.6%), and 2 had stage IV(1.6%). In 77 patients with RT plus chemotherapy, 36 patients were treated with VBP(vinblastin, bleoycin, cisplainum), 39 patients with cisplatinum plus 5-FU and 2 patients with 5-FU. Results : Complete response after external RT(3960cGy-5500cGy)was achieved in 61 patients(50%). He actuarial 5 year and 9 year survival rate was 57.8% and 53.9%, respectively. Five year actuarial survival rate was 63.1% with RT alone(n=45) and 55.9% with RT plus chemotherapy(n=77). Their 5 year survival rate was 35.5% for 1 course of ICR and 67% for 2 courses of ICR. There was statistically significant advantage of survival with RT alone group who were treated with 2 coursed of ICR and dose to the A point≥8000cGy(4/25 died).

Full Text Available Cancer is an important health problem due to the high morbidity and mortality which it produces. The first cause of women death between 30 and 44 years old in Cuba is cervix carcinoma. This is a case of a 39 year old woman who presented to the secondary health care level with a stage IV cervix tumor where it was diagnosed, it simulated an anaemic syndrome due to another cause. The histological and imaging studies were concluding. Primary prevention of this kind cancer by means of health education and searching in the risk population are paramount. The program of early detection still has difficulties. The presentation of this case is aimed at teaching so as documentary exposition for professionals of primary health care attention, gyneco-obstetricians, internists and any other clinical specialty derived.

2016-08-01

The World Health Organization (WHO) defines PEComas as mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular cells. Uterus is the most common site of a subgroup of PEComas not otherwise specified(NOS). PEComas of the uterine cervix are extremely rare, and only thirteen cases have been described in the English literature to date. In this review, we summarize the available data concerning diagnostics, immunohistochemical analysis, genetics and treatment of cervical PEComas. Radical hysterectomy with bilateral salpingooophorectomy is the best surgical approach available. Adjuvant therapy in its present form is not efficient. Therefore, further studies are needed to evaluate the newest treatment strategies. Copyright © 2016 Elsevier GmbH. All rights reserved.

Both small cell carcinoma and sarcomatoid carcinoma of the urinary bladder are highly aggressive tumors, and a concurrence of these tumors is extremely rare. We report a case of urinary bladder cancer with small cell carcinoma as a predominant component, accompanied by sarcomatoid carcinoma and conventional urothelial carcinoma (UC). Although the small cell carcinoma component had resolved on receiving chemoradiotherapy, rapid growth of the residual tumor led to a fatal outcome. A 47-year-old man presented with occasional bladder irritation and had a 2-year history of asymptomatic hematuria. Cystoscopy revealed a huge mass in the urinary bladder, and transurethral resection was performed. Microscopically, small cell carcinoma was detected as the major tumor component. Spindle-shaped sarcomatoid cells were also observed that were intermingled with small cell carcinoma and conventional UC. In addition, a sheet-like growth of the lipoblast-like neoplastic cells was observed focally. Initially, by providing chemoradiotherapy, we achieved a marked tumor regression; however, the tumor rapidly regrew after the completion of chemoradiotherapy, and the patient underwent radical cystectomy. Only conventional UC and sarcomatoid carcinoma were identified in the cystectomy specimen. The patient died of the disease 4 months after cystectomy. Urinary bladder cancer may include a combination of multiple aggressive histologies as in the present case. Because the variation in the tumor components may affect the efficacy of therapy, a correct diagnosis of every tumor component is necessary. Copyright © 2016 Elsevier GmbH. All rights reserved.

Full Text Available Aim: To report the outcome of carcinoma of the uterine cervix patients treated radically by external beam radiotherapy (EBRT and high-dose-rate (HDR intracavitary radiotherapy (ICRT. Materials and Methods: Between January 1997 to December 2001, a total of 550 newly diagnosed cases of carcinoma of the uterine cervix were reported in the department. All cases were staged according to the International Federation of Gynecologists and Oncologists (FIGO staging system, but for analytical convenience, the staging was limited to stages I, II, III, and IV. Out of the 550 cases, 214 completed radical radiotherapy (EBRT + HDR-ICRT and were retrospectively analyzed for presence of local residual disease, local recurrence, distant metastases, radiation reactions, and disease-free survival. Results: There were 7 (3.27%, 88 (41.1%, 101 (47.1%, and 18 (8.4% patients in stage I, II, III, and IV, respectively. The median follow-up time for all patients was 43 months (range: 3-93 months and for patients who were disease free till the last follow-up it was 59 months (range: 24-93 months. The overall treatment time (OTT ranged from 52 to 73 days (median 61 days. The 5-year disease-free mean survival rate was 58%, 44%, 33%, and 15%, with 95% confidence interval of 48 to 68, 37 to 51, 24 to 35, and 6 to 24 for stages I, II, III, and IV, respectively. There were 62 (28.97% cases with local residual disease, 35 (16.3% developed local recurrence/distant metastases, 17 (7.9% developed distant metastases, and 9 (4.2% had local recurrence as well. Discussion and Conclusion: The overall outcome was poor in advanced stage disease, but might be improved by increasing the total dose, decreasing overall duration of treatment, and by adding chemotherapy in patients with disease limited to the pelvis.

A schedule of radiotherapy, including the use of the Cathetron for advanced carcinoma of the cervix. Chapter 3

International Nuclear Information System (INIS)

Ward, A.J.; Stubbs, B.; Dixon, B.; Firth, L.A.

1980-01-01

Since 1971, 78 patients with stage IIb and III carcinoma of the cervix have been treated in Leeds with the high-activity Cathetron afterloading device combined with external irradiation directed at the whole of the defined tumour volume. In four or more years of follow-up, no difference in the tumour response was found whether the external irradiation was given in an environment of air or hyperbaric oxygen. Although the results for all patients were satisfactory from the point of view of local control and survival, it was felt that an attempt should be made to devise a scheme which would reduce the level of morbidity, particularly in the bowel. Thus a modified treatment schedule has been adopted in the last two years in which the external irradiation component of the treatment is given by conventional fractionation and the volume treated is determined by lymphangiograms.

The nucleoli in squamous cell carcinoma of cervix uteri with special reference to early changes of irradiation by metrical comparison

International Nuclear Information System (INIS)

Ishii, Hiroki

1976-01-01

The mean number of nucleoli in a cancer cell is 1.51, which is apparently larger in number than that in a normal cell (1.17), although there are slight differences in number by the histological types of cancer. Although there are slight differences in the location and shape of nucleoli between the histological types of cancer, they resembles those of normal cells in shape and location (the nucleoli are located in the center, and circular or circuloid in shape). The size of nucleoli is 1.58 times larger than that of normal cells both by histogram and by mean values. According to the histological classification, the nucleoli of keratinized large cells were more enlarged than those of undifferentiated small cells. As for the change in the number of nucleoli due to irradiation, the tendency to increase in number began to be noted with 500 rads irradiation, and becomes more remarkable with the increase of dose. Especially, it is observed more often in small cell carcinoma than large cell carcinoma. No remarkable change was observed in their location and shape with 1,000 or less rads. However, with about 2,000 rads nucleoli tended to be irregular in shape. There was a tendency of increasing in size with 2,000 rads, on histogram and mean values. Therefore, the change of nucleoli consists of the increase in number and swelling. This fact is important in radiation pathology as well as in the diagnosis of radiosensitivity. (N. Kanao)

Clinical and experimental investigation on small intestinal injury following radiation therapy for carcinoma of uterine cervix

International Nuclear Information System (INIS)

Asakura, Midori

1977-01-01

Radiation injury of the small bowel was observed in 6 of 460 patients with carcinoma of uterine cervix who were treated by radiation between April 1966 and December 1973 at Tokyo Women's Medical College, Department of Radiology. Three of these 6 patients were treated conservatively and the other 3 others underwent surgery but died subsequently. Clinically and surgically these 6 patients showed marked adhesions of intestinal loops, which may be accounted for by the radiation injury of the small bowel. Clinical experience has shown that it is necessary to use a small radiation field to decrease small bowel injury from radiation. An experiment using abdominal radiation in mice confirmed that LD sub(50/30) is larger with a center split, maintaining equal integral doses. In adult dogs, severe small bowel obstruction was observed with over 4000 rad irradiation. Small bowel injury was milder in case with center split, intracavitary irradiation, and small radiation field. It was concluded that center split is one of the methods of preventing radiation injury of the small bowel. (Evans, J.)

Role of Visual Inspection of Cervix with Acetic Acid (VIA in Detecting Precancerous Lesions of Cervix

Directory of Open Access Journals (Sweden)

Kamrun Nessa

2014-01-01

Full Text Available Background: Carcinoma of cervix is the most common malignancy in female and a major public health problem worldwide. It is the leading cause of death from cancer among women in low resource settings. In Bangladesh, mortality rate is high as most of the cases with cervical cancer are diagnosed in advanced stage. World Health Organization considers cervical cancer as a preventable disease as it can be identified in preinvasive stage. Considerable efforts have been given in detection and treatment of the condition all over the world. A number of cervical cancer screening tests are available. Among them, visual inspection of cervix with acetic acid is rational and can be competently performed by physicians with proper training. Objective: To find out the feasibility of the visual inspection of cervix with acetic acid for the detection of the precancerous lesions of the cervix in our country. Materials and Methods: This cross sectional, analytical study was carried out among the patients attending the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU who were VIA positive and sent for colposcopy in the colposcopy clinic in the department of Obstetrics and Gynecology in BSMMU from June to December 2004. Two hundred samples were considered for this study. Results: Out of 200 cases, colposcopically 85% had CIN and invasive lesions, 4% had inflammatory lesions while 11% had normal findings. Colposcopy directed punch biopsy revealed positive lesions in 81%, 4% had inflammatory lesions while 15% had normal findings. Conclusion: The study concluded that VIA and colposcopy are the important methods in the evaluation of cervical premalignancy. VIA may be an important tool for screening of cervical cancer in low resource settings as it is simple, easy to perform and cost-effective. After screening, VIA positive cases must be referred for colposcopic evaluation. We can screen cervical cancer by VIA all over the country and thus reduce

A clearcut definition of the transition from the cervix to the lower uterine segment is lacking. We therefore evaluated the location of the anatomic border between the cervix and the uterine corpus. Using both morphometry and immunohistochemisty, we examined the epithelial and stromal cell types in this transition zone. In 26 patients, longitudinal sections from the cervix uteri up to the fundus uteri were paraffin embedded and immunohistochemically stained for BCL2, keratin 5, Ki-67, CD10, and CD34. Examination of the slides resulted in the identification of a junctional zone in the cranial portion of the cervix, which is characterized by a usually abrupt morphologic and immunohistochemical transition from an endocervical-type mucinous epithelium to a ciliated tubal-like epithelium and a slow transition in stromal marker expression patterns. This epithelial transition was characterized by its intense keratin 5 and BCL2 staining with accompanying Ki-67 expression in the tubal-like epithelium, whereas the endocervical epithelium was largely negative for these markers. CD10 expression was usually quite intense directly around endocervical invaginations, but the remaining stroma was negative. Toward the endometrial cavity, expression increased and endometrial stroma displayed full thickness expression for CD10. CD34 showed a reverse pattern to CD10, with moderate expression in the endocervical stroma, which disappeared in the endometrial stoma. The immunohistochemical identification of this transition may allow a more objective determination of the extension of endometrial carcinoma into the cervix in cases that are morphologically problematic. Furthermore, as ciliated tubal-like epithelium is invariably found cranial to the uterine-cervix-isthmus junction, a diagnosis of tubal metaplasia should not be made in this region and tubal-like epithelium is not indicative of a metaplastic process.

Evaluation of radiation doses on critical organs in the treatment of cancer of the cervix using HDR-brachytherapy

International Nuclear Information System (INIS)

Soares, Taciana; Jansem, Teresa

2000-01-01

High dose-rate (HDR) brachytherapy is one type of treatment of the cervix carcinoma. During the planning for this therapy, especial attention is given to proximal normal organs such as bladder and rectum. In fact, due to their radiosensibility and localization, bladder and rectum are considered as critical organs. In this work we have studied the influence of the positioning of patient legs in the dose delivered to these critical organs in the treatment of cancer of the cervix using HDR-brachytherapy.

1992-01-01

From January 1975 to December 1984, 41 patients were treated by combined radiotherapy and surgery at Institut Gustave Roussy for Stage IB (288) and II (proximal) (103) carcinoma of uterine cervix. Standard treatment consisted of pre-operative utero-vaginal brachytherapy (60 Gy) using a mould technique followed by colpho-hysterectomy and external iliac lymphadenectomy. Overall 5 year actuarial survival for whole population was 87% and disease-free survival 85%. Locoregional relapse occurred in 23 patients (5%). Of these, 12 where central pelvic failures, 8 regional failures and 3 combined central and regional failures. Of 36 systemic relapses (8%), 12 relapsed concurrently in pelvis. Five year actuarial pelvic disease-free, disease-free and overall survival was 87, 85 and 87%, resp., for the whole population. 340 patients developed one or more complications [Grade 1: 198/441 (44%), Grade 2: 121/441 (27%) and Grade 3 or 4: 21/441 (4.7%)]. Five year actuarial survival for the whole population was poorer for histologically node positive than for node negative (89 vs. 55%, p<0.0001). Pre-operative brachytherapy by surgery can provide good local control with acceptable morbidity in early cervical cancer. (author). 39 refs.; 4 figs.; 4 tabs

Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

Purpose of the radio-therapy is maximize the radiation dose to the tumor while minimizing the dose to the critical organ. Carcinoma of the uterine cervix treatment are external irradiation or an interstitial brachytherapy make use of isotope. Brachytherapy is a method of radiotherapy in advantage to achieve better local control with minimum radiation toxicity in comparison with external irradiation because radiation dose is distributed according to the inverse square low of gamma-ray emitted from the implanted sources. Authors make use of the patients data which 192 Ir gives medical treatment intracavity. Intracavitary radiation of the uterine cervix cancer, critical organ take 20% below than exposure dose of A point in the ICRU report. None the less of the advice, Radiation proctitis and radiation cystitis are frequent and problematic early complications in patients treated with radiation for the uterine cervix cancer. In brachytherapy of uterine cervical cancer using a high dose rate remote afterloading system, it is of prime importance to deliver a accurate dose in each fractionated treatment by minimizing the difference between the pre-treatment planned and post-treatment calculated doses. Use of packing to reduce late complications intracavitary radiation of the uterine cervix cancer. Bladder and rectum changes exposure dose rate by radiotherapy make use of packing.

Cervix uteri. Strategy for the management of cancer of the cervix uteri

International Nuclear Information System (INIS)

Takahashi, S.

1984-01-01

In our department external irradiation is given priority over intracavitary (radium) therapy for the treatment of carcinoma of the cervix uteri. Our policy is to irradiate the volume containing the primary lesion, parametrium and pelvic lymph nodes to a dose of 40.0 Gy in about 4 weeks for stages I and IIa, or 50.0 Gy over 5 weeks for stages IIb and III. For stages I and IIa, intracavitary radium therapy is additionally given to a dose of 28.0-30.0 Gy at ''point A'', 7-10 days after the external irradiation, by means of two fractions with an interval of 7-10 days. For stages IIb and III, further external irradiation is carried out to give an additional dose of 20.0 to 25.0 Gy to the cervix and parametrium over 2 weeks by means of radiation fields of reduced size. If the size of the tumour in stages IIb and III is considerably reduced after the initial dose of 50.0 Gy, and the dose to point A is 40.0 Gy, intracavitary therapy is carried out without the additional small field irradiation. The intracavitary therapy is given twice with an interval of 8 days. For stage IV without distant metastases the treatment policy is the same as that in stage III; for stage IV with distant metastases, only whole pelvis irradiation is performed, to a dose of 50.0 Gy over 5 weeks

The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

Merkel cell carcinoma: is this a true carcinoma?

Science.gov (United States)

Jankowski, Marek; Kopinski, Piotr; Schwartz, Robert; Czajkowski, Rafal

2014-11-01

Recent years have brought an enhanced understanding of Merkel cell carcinoma (MCC) biology, especially with regard to the Merkel cell polyoma virus as a causative agent. Differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative MCC in morphology; gene expression, miRNA profiles and prognosis have been reported. Origin of MCC is controversial. Presence of neurosecretory granules has suggested that these carcinomas originate from one of the neurocrest derivatives, most probably Merkel cells; the name Merkel cell carcinoma is now widely accepted. Expression of PGP 9.5, chromogranin A and several neuropeptides, initially regarded as specific markers for neural and neuroendocrine cells, has recently been shown in a subset of lymphomas. MCC commonly expresses terminal deoxynucleotidyl transferase and PAX5. Their co-expression under physiologic circumstances is restricted to pro/pre-B cells and pre-B cells. These findings lead to the hypothesis by zur Hausen et al. that MCC originates from early B cells. This review was intended to critically appraise zur Hausen's hypothesis and discuss the possibility that MCC is a heterogenous entity with distinct subtypes. © 2014 John Wiley & Sons A/S.

Red Dot Basal Cell Carcinoma: Report of Cases and Review of This Unique Presentation of Basal Cell Carcinoma.

Science.gov (United States)

Cohen, Philip R

2017-03-22

Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered. Mohs surgery is the treatment of choice; in some of the patients, the ratio of the area of the postoperative wound to that

There are still controversies about the therapeutic strategies and subsequent outcome in head and neck Merkel cell carcinoma. Clinicopathological data of 23 Merkel cell carcinomas, 93 cutaneous head and neck squamous cell carcinomas (HNSCCs), 126 malignant melanomas, and 91 primary parotid gland carcinomas were comprehensively analyzed. Merkel cell carcinomas were cytokeratin 20 (CK20)/neuron-specific enolase (NSE)/chromogranin A (CgA)/synaptophysin (Syn)/thyroid transcription factor-1 (TTF-1)/MIB1 immunostained. All Merkel cell carcinomas underwent wide local excision. Parotidectomy/neck dissection was performed in 40%/33% cutaneous Merkel cell carcinoma and 100%/100% in parotid gland Merkel cell carcinoma. Five-year recurrence-free interval (RFI)/overall survival (OS) was significantly higher in malignant melanoma (81/80%) than in cutaneous Merkel cell carcinoma/HNSCC. Interestingly, 5-year RFI/OS was significantly higher in Merkel cell carcinoma (61%/79%) than in HNSCC (33%/65%; p Merkel cell carcinoma and parotid gland carcinomas, nor in the immunohistochemical profile. Five-year RFI/OS was significantly better in cutaneous Merkel cell carcinoma when compared with TNM classification matched HNSCC. Five-year RFI/OS was comparable in parotid gland Merkel cell carcinoma and other primary parotid gland malignancies. © 2016 Wiley Periodicals, Inc.

Purpose/Objective: Interstitial fluid pressure (IFP) has been found to be elevated in cervical carcinomas. This study sought to evaluate IFP as a potential early measure of tumor response to radiation therapy. Identification of poor responders early in the course of treatment may allow the clinician to modify the treatment strategy early in the course of therapy. Materials and Methods: IFP was measured using the wick-in-needle technique in 42 patients undergoing definitive radiotherapy for carcinoma of the cervix. Measurements were taken before and after external beam radiation treatment (EBRT) in 25, after intracavitary treatment (ICT) in 7, and after both EBRT and ICT in 10 patients. An additional 10 patients had weekly measurements during radiotherapy. Tumor stage, size, hemoglobin, and clinical response were assessed and correlated with IFP readings. Results: All initial IFP readings were elevated. The extent of elevation did not correlate with outcome (p=0.76) or stage (p=0.6). Smaller tumors had a higher initial IFP (p=0.02). Tumor response correlated with change in IFP readings (p=0.01), tumor size (0.04), hemoglobin (p=0.01), and stage (0.04). On multivariate analysis, change in IFP remained an independent predictor of response. The IFP change from pretreatment to post-EBRT was - 13±3 in complete responders versus 4±11 and 18±10 in the partial and nonresponders respectively (p=0.01). In those with post-ICT readings, the change was -18±4 in complete responders versus 54±18 in the partial responders (p=0.01). In 10 patients undergoing weekly measurement, 8 complete responders had decreasing IFP measurements. An average fall of 51.6% was seen in five patients at < 1620cGy despite little or no change in tumor size, and by 2700cGy (average decrease 31%) in the remaining 3 complete responders. Nonresponders had either no change or an increase in IFP throughout EBRT. Conclusion: IFP is elevated in tumors of the uterine cervix. Decreasing IFP measurement

Purpose: The objective of this work is to evaluate and compare Large field IMRT and RapidArc planning for Carcinoma Cervix and Para-aotic node irradiation. Methods: In this study, ten patients of Cervix with para-aotic node have been selected with PTV length 35+2cm. All plans were generated in Eclipse TPS V10.0 with Dynamic IMRT and RapidArc technique using 6MV photon energy. In IMRT planning, 7 fields were chosen to get optimal plan and in RapidArc, double Full arc clockwise and counter clockwise were used for planning. All the plans were generated with single isocenter and calculated using AAA dose algorithm. For all the cases the prescribed dose to PTV was same and the plan acceptance criteria is; 95% of the PTV volume should receive 100% prescribed dose. The tolerance doses for the OAR’s is also taken in to account. The evaluation criteria used for analysis are; 1) Homogeneity Index, 2) Conformity Index, 3) Mean Dose to OAR’s, 4)Total monitor units delivered. Results: DVH analysis were performed for both IMRT and RapidArc planning. In both the plans, 95% of PTV volume receives prescribed dose and maximum dose are less than 107%. The conformity index are same in both the techniques. The mean Homogeneity index are 1.036 and 1.053 for IMRT and RapidArc plan. The mean (mean + SD) dose of bladder and rectum in IMRT is 44.2+1.55, 42.05+2.52 and RapidArc is 46.66+1.6, 44.2+2.75 respectively. There is no significant difference found in Right Femoral head, Left Femoral head and Kidney doses. It is found that total MU’s are more in IMRT compared with RapidArc planning. Conclusion: In the case of cervix with Para-arotic node single isocenter irradiation, IMRT planning in large-field is better compared to RapidArc planning in terms of Homogeneity Index and mean dose of Bladder and Rectum

The behaviour of each basal cell carcinoma is known to be different according to the histological growth pattern. Among these aggressive lesions, sclerodermiform basal cell carcinomas are the most common type. This is a challenging-to-treat lesion due to its deep tissue invasion, rapid growth, risk of metastasis and overall poor prognosis if not diagnosed in early stages. To investigate if sclerodermiform basal cell carcinomas are diagnosed later compared to non-sclerodermiform basal cell carcinoma Method: All lesions excised from 2000 to 2010 were included. A pathologist classified the lesions in two cohorts: one with specimens of non-aggressive basal cell carcinoma (superficial, nodular and pigmented), and other with sclerodermiform basal cell carcinoma. For each lesion, we collected patient's information from digital medical records regarding: gender, age when first attending the clinic and the tumor location. 1256 lesions were included, out of which 296 (23.6%) corresponded to sclerodermiform basal cell carcinoma, whereas 960 (76.4%) were non-aggressive subtypes of basal cell carcinoma. The age of diagnosis was: 72.78±12.31 years for sclerodermiform basal cell and 69.26±13.87 years for non-aggressive basal cell carcinoma (Pbasal cell carcinomas are diagnosed on average 3.52 years later than non-aggressive basal cell carcinomas. Sclerodermiform basal cell carcinomas were diagnosed 3.40 years and 2.34 years later than non-aggressive basal cell carcinomas in younger and older patients respectively (P=.002 and P=.03, respectively). retrospective design. The diagnostic accuracy and primary clinic conjecture of sclerodermiform basal cell carcinomas is quite low compared to other forms of basal cell carcinoma such as nodular, superficial and pigmented. The dermoscopic vascular patterns, which is the basis for the diagnosis of non-melanocytic nonpigmented skin tumors, may not be particularly useful in identifying sclerodermiform basal cell carcinomas in early stages

Full Text Available CONTEXT AND OBJECTIVE: Cancer of the uterine cervix is still very common in Brazil. It is important to evaluate factors that influence its prognosis. The aim here was to analyze the prevalence of prognostic anatomoclinical factors among patients with carcinoma of the uterine cervix undergoing radical hysterectomy. DESIGN AND SETTING: Cross-sectional study on 301 patients with invasive carcinoma of the uterine cervix who underwent Level III Piver-Rutledge hysterectomy surgery at São Marcos Hospital. METHODS: The following variables were analyzed: age, histological type, degree of differentiation, invasion of lymphatic, vascular and perineural space, lymph node metastasis, distance to nearest margin, tumor invasion depth, vaginal cuff size, largest diameter of the tumor, presence of necrosis and surgical margin involvement. Descriptive statistics, multiple regression analysis, Kaplan-Meier survival curves and the log-rank test were performed. A significance level of 5% was used. RESULTS: The mean age was 48.27 years. The following were not important for the prognosis, in relation to survival analysis: degree of differentiation and tumor invasion depth; presence of lymphatic, blood and perineural invasions; distance to nearest margin; and vaginal cuff size. Tumor size (P < 0.036, presence of lymph node metastasis (P < 0.0004, necrosis (P < 0.05 and surgical margin involvement (P < 0.0015 presented impacts on survival. The overall survival with 98 months of follow-up was 88.35%. CONCLUSION: The most prevalent prognostic factors were the presence of lymph node metastasis, tumor size and surgical margin involvement.

2014-09-01

Full Text Available Background: Mast cells are heterogeneous group of immune cells involved in multiple biological events. The significance of mast cells in uterine tumor surveillance has been studied with conflicting results. The presence of mast cell in tumor has been described as evidence of a host immunologic anti tumor response and if they are abundant the prognosis is good. However in other studies, with the help of different granules of mast cell, it is said to be very closely related with angiogenesis and tumor invasion. The study aims to analyze the histomorphologic changes with special reference to mast cells in different neoplastic and non neoplastic disease of uterine cervix, and also the relationship of the mast cell population with degree of anaplasia and mitotic figures.Materials and methods: Cervical biopsies received in the department of Pathology for HPE were stained with H& E stain and toludine blue for the identification of mast cellResult: Out of a total of 100 cases, 82 were non neoplastic cases with the mean mast cell count of 83.73 and mean age of patient being 44.30 year. Eighteen neoplastic cases were included which had mean mast cell count of 13.5 and mean age of 49.5 year.Conclusion: Mast cell was found to be highest in non Neoplastic lesion with increase count in polypoidal cervicitis. There was a statistical significance variation between mast cell count in neoplastic and non Neoplastic disease of the cervix. However,role of age in mast cell count was least significant.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11594 Journal of Pathology of Nepal; Vol.4,No. 8 (2014 658-662

Downregulation of six microRNAs is associated with advanced stage, lymph node metastasis and poor prognosis in small cell carcinoma of the cervix.

Full Text Available BACKGROUND: Small cell carcinoma of the cervix (SCCC is very rare, and due to the long time period required to recruit sufficient numbers of patients, there is a paucity of information regarding the prognostic factors associated with survival. MicroRNAs (miRNAs have been used as cancer-related biomarkers in a variety of tumor types, and the objective of this study was to determine whether microRNA expression profiles can predict clinical outcome in SCCC. METHODOLOGY/PRINCIPAL FINDINGS: Forty-four patients with SCCC who underwent radical hysterectomy between January 2000 and October 2009 were enrolled. Using the GeneCopoeia All-in-One™ Customized Human qPCR Primer Array, the expression profiles of 30 miRNAs associated with tumor metastasis was obtained from the formalin-fixed paraffin embedded samples of all 44 patients. Seven miRNAs, has-let-7c, has-miR-10b, has-miR-100, has-miR-125b, has-miR-143, has-miR-145 and has-miR-199a-5p were significantly down-regulated in advanced stage SCCC patients (FIGO IB2-IV compared to early stage SCCC patients (FIGOIB1. Among, downregulation of six miRNAs, has-let-7c, has-miR-100, has-miR-125b, has-miR-143, has-miR-145 and has-miR-199a-5p were significantly associated with lymph node metastasis and reduced survival in SCCC. Kaplan-Meier survival analyses revealed that SCCC patients with low expression of has-miR-100 (P = 0.019 and has-miR-125b (P = 0.020 projected a significant tendency towards poorer prognosis. CONCLUSIONS/SIGNIFICANCE: This study demonstrates that downregulation of 7 miRNA associated with advanced stage, 6 miRNAs with metastasis and 2 with poor prognosis in SCCC. Functional analysis of these miRNAs may enhance our understanding of SCCC, as altered expression of specific miRNAs may regulate the metastatic pathway and provide novel targets for therapy.

Full Text Available Based on a case of gastric antral vascular ectasia (watermelon stomach that was associated with hemorrhagic pericarditis, small cell lung carcinoma with mediastinal lymph node metastases and a synchronous squamous cell carcinoma of the base of the tongue, the authors made a review of the clinical, endoscopic and histopathological aspects of this type of gastropathy, and its association with other diseases, and of the results of its endoscopic therapy. The causes of hemorrhagic pericarditis are considered, emphasizing the necessity to know if the effusion has a malignant etiology. To the best of our knowledge the association of watermelon stomach to small cell lung carcinoma and squamous cell carcinoma of the base of the tongue has not yet been described. Extensive metastases to mediastal lymph nodes are common to small cell lung carcinoma.

Background and purpose: The possibility of using γH2AX foci as a marker of DNA damage and as a potential predictor of tumour response to treatment was examined using biopsies from 3 sets of patients with advanced carcinoma of the cervix. The relation between endogenous γH2AX expression and hypoxia was also examined. Materials and methods: Set 1 consisted of 26 biopsies that included pre-treatment and 24 h post-radiation treatment samples. Pre-treatment biopsies from 12 patients in Set 2 were used to develop image analysis software while pre-treatment biopsies from 33 patients in Set 3 were examined for the relation between staining for the hypoxia marker pimonidazole and endogenous γH2AX expression. Formalin-fixed paraffin-embedded sections were analyzed after antigen retrieval and fluorescence antibody labeling for the hypoxia markers CAIX or pimonidazole in combination with γH2AX staining. Results: Before treatment, 24 ± 19% of cells contained γH2AX foci, with most positive cells containing fewer than 5 foci per nucleus. Twenty-four hours after exposure to the first fraction of 1.8-2.5 Gy, 38 ± 19% contained foci. CAIX positive cells were 1.4 times more likely to exhibit endogenous γH2AX foci, and pimonidazole-positive cells were 2.8 times more likely to contain γH2AX foci. For 18 patients for whom both pre-treatment and 24 h post-irradiation biopsies were available, local control was unrelated to the fraction of cells that retained γH2AX foci. However, 24 h after irradiation, tumours that had received 2.5 Gy showed a significantly higher fraction of cells with residual γH2AX foci than tumours given 1.8 Gy. Conclusions: Endogenous γH2AX foci are enriched in hypoxic tumour regions. Small differences in delivered dose can produce quantifiable differences in residual DNA damage that can overshadow inter-tumour differences in response.

Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of Merkel cell carcinoma in a young HIV positive patient with Merkel Cell polyomavirus detected in the tumor.

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 Abstract Background Mucosal squamous cell carcinoma of the head and neck is a disease of high mortality and morbidity. Interactions between the squamous cell carcinoma and the host's local immunity, and how the latter contributes to the biological behavior of the tumor are unclear. In vivo studies have demonstrated sequential mast cell infiltration and degranulation during squamous cell carcinogenesis. The degree of mast cell activation correlates closely with distinct phases of hyperkeratosis, dysplasia, carcinoma in-situ and invasive carcinoma. However, the role of mast cells in carcinogenesis is unclear. Aim This study explores the effects of mast cells on the proliferation and gene expression profile of mucosal squamous cell carcinoma using human mast cell line (HMC-1 and human glossal squamous cell carcinoma cell line (SCC25. Methods HMC-1 and SCC25 were co-cultured in a two-compartment chamber, separated by a polycarbonate membrane. HMC-1 was stimulated to degranulate with calcium ionophore A23187. The experiments were done in quadruplicate. Negative controls were established where SCC25 were cultured alone without HMC-1. At 12, 24, 48 and 72 hours, proliferation and viability of SCC25 were assessed with MTT colorimetric assay. cDNA microarray was employed to study differential gene expression between co-cultured and control SCC25. Results HMC-1/SCC25 co-culture resulted in suppression of growth rate for SCC-25 (34% compared with 110% for the control by 72 hours, p Conclusion We show that mast cells have a direct inhibitory effect on the proliferation of mucosal squamous cell carcinoma in vitro by dysregulating key genes in apoptosis and cell cycle control.

Purpose: Aim of this study is to determine the dosimetric influence of Filtered and Flatting Filter Free Photon Beam of 10 MV energy on RA planning for Ca. Cervix. Methods: CT data sets of eleven patients reported with carcinoma cervix were used for RA planning for 10MV -FFB and 10MV-FFFB. RA plans were generated using two full arcs.All RA plans were generated to deliver a dose of 50.4Gy in 28 fractions for PTV and ALARA for OAR’s. All plans were analysed for PTV Coverage, conformity Index, homogeneity index, dose to OAR’s, integral dose to normal tissue and total monitor units were studied. Results: DVH was used to evaluate RA plans for both 10MV-FFB and 10MV-FFFB photon beam. Planning results show a comparable PTV coverage for both energies. Results shows volume of PTV receiving prescription dose were 95.10+ 0.09% and 95.09 +0.11%, and volume of PTV receiving a dose of 107% is 0.45+0.96% and 5.25+8.9%, homogeneity index (HI) were 1.051+0.007 and 1.066+0.008, Conformity Index(CI) were 1.003+0.019 and 1.012+0.013, Mean Integral dose were 2.65+0.34 and 2.60+0.33(*10−5Gy.cm3) for 10MV-FFB and 10MV-FFFB respectively. 10MV-FB shows statistically significant (p<0.05) improvement in mean doses to bladder, rectum, bowel and mean total number of MU’s and also shows remarkable decrease in mean total no. of MU’s by 43.7% in comparison to 10MV-FFFB. There is statistically significant (p<0.05) difference found in CI and HI for 10MV-FB in comparison to 10MV -FFF beam. 10MV-FFFB shows statistically significant (p<0.05) for mean NTID and delivers 1.65 % less NTID in comparison to 10 MV- FB. Conclusion: 10MV-FB is superior to 10MV-FFFB for rapid arc planning in case of Cervix carcinomas, it offers better target coverage and OAR’s sparing, comparable mean Integral dose to normal tissues and 10 MV- FB also produced highly conformal and homogeneous dose distribution in comparison to 10MV-FFFB.

Associations between lymph node metastasis and the different variables were evaluated by means of the chi-square test, Fisher's exact test and multiple logistic regression. RESULTS: Pelvic lymph node metastasis was found in 65 patients (22.5%. The following risk factors for lymph node metastasis were identified by multivariate analysis: hemoglobin level <10.0 g% (OR = 3.6; 95% CI: 1.210.7, tumor invasion of the middle third (OR = 3.3; 95% CI: 1.110.7 and deep third of the uterine cervix (OR = 5.4; 95% CI: 1.717.3, absent or slight inflammatory reaction in the uterine cervix (OR = 2.4; 95% CI: 1.15.2 and keratinizing squamous cell carcinoma (OR = 3.3; 95% CI: 1.47.6. CONCLUSIONS: This study identified four risk factors for pelvic lymph node metastasis in patients with carcinoma of the uterine cervix at stages IB and IIA. Of these, three are not usually described in literature as predictive variables for lymph node metastasis (preoperative anemia, absent or slight inflammatory reaction and keratinizing of squamous cell carcinoma.

Squamous cell carcinoma arising in an odontogenic cyst is uncommon. The diagnosis of carcinoma arising in a cyst requires that there must be an area of microscopic transition from the benign epithelial cyst lining to the invasive squamous cell carcinoma. We report a histopathologically proven case of squamous cell carcinoma arising in a residual mandibular cyst in a 54-year-old woman.

This study aims to compare the doses received for patients submitted to brachytherapy High Dose Rate (HDR) brachytherapy, a method of treatment of the cervix carcinoma, performed in the planning system PLATO BPS with the doses obtained by Monte Carlo simulation using the radiation transport code MCNP 5 and one female anthropomorphic phantom based on voxel, the FAX. The implementation of HDR brachytherapy treatment for the cervix carcinoma consists of the insertion of an intrauterine probe and an intravaginal probe (ring or ovoid) and then two radiographs are obtained, anteroposterior (AP) and lateral (LAT) to confirm the position of the applicators in the patient and to allow the treatment planning and the determination of the absorbed dose at points of interest: rectum, bladder, sigmoid and point A, which corresponds anatomically to the crossings of the uterine arteries with ureters The absorbed doses obtained with the code MCNP 5, with the exception of the absorbed dose in the rectum and sigmoid for the simulation considering a point source of 192 Ir, are lower than the absorbed doses from PLATO BPS calculations because the MCNP 5 considers the chemical compositions and densities of FAX body, not considering the medium as water. When considering the Monte Carlo simulation for a source with dimensions equal to that used in the brachytherapy irradiator used in this study, the values of calculated absorbed dose to the bladder, to the rectum, to the right point A and to the left point A were respectively lower than those determined by the treatment planning system in 33.29, 5.01, 22.93 and 19.04%. These values are almost all larger than the maximum acceptable deviation between patient planned and administered doses (5 %). With regard to the rectum and bladder, which are organs that must be protected, the present results are in favor of the radiological protection of patients. The point A, that is on the isodose of 100%, used to tumor treatment, the results indicate

Xeroderma pigmentosum is a rare autosomal-recessive disorder that appears in early childhood. Squamous cell carcinoma is not uncommon in patients with xeroderma pigmentosum and mostly involving the face, head, neck, and scalp. However, squamous cell carcinoma of the scalp may exhibit an aggressive course. Here, we present a huge squamous cell carcinoma of the scalp in a three-years-old child with xeroderma pigmentosum. In addition, we illustrate the challenges of a child with xeroderma pigmentosum who grows up in a sunny environment where the possibility of early onset of squamous cell carcinoma is extremely high in any suspected skin lesion. In xeroderma pigmentosum patients, squamous cell carcinoma of the scalp can present early and tends to be unusually aggressive. In sunny areas, proper education to the patient and their parents about ultra-violet light protection and early recognition of any suspicious lesion could be life-saving.

Twelve patients with primary or locally recurrent squamous carcinoma of the cervix were treated with constant internal iliac artery infusion of cisplatin (CDDP) via a totally implantable chemotherapy pump. Seven previously untreated patients received standard external and interstitial radiotherapy (RT) in conjunction with CDDP infusion. Five patients with isolated pelvic recurrences received CDDP therapy only. The chemotherapy pump was refilled weekly on an outpatient basis. All nine evaluable patients developed unilateral or bilateral lower extremity pain which responded to dosage reduction. No renal or marrow toxicity was seen. Both of the evaluable patients treated for recurrent tumor died 32 and 60 weeks after initiation of treatment. The seven patients treated primarily with RT + CDDP infusion include one who expired with persistent tumor and one with no evidence of disease (NED) after exenteration for a pelvic recurrence at 48 and 85 weeks respectively. The five remaining patients are NED at 12 to 60 weeks. Constant internal iliac artery infusion of CDDP via an implantable chemotherapy pump can be performed with acceptable toxicity. The preliminary results suggest that further study in previously untreated undergoing concurrent radiotherapy is warranted

Currently, non-small cell lung carcinomas are primarily classified by light microscopy. However, recent studies have shown that poorly-differentiated tumors are more accurately classified by immunohistochemistry. In this study, we investigated the use of immunohistochemical analysis in reclassifying lung carcinomas that were originally diagnosed as squamous cell carcinoma. Tumor slides and blocks were available for histologic evaluation, and tissue microarrays were constructed from 480 patients with resected lung carcinomas originally diagnosed as squamous cell carcinoma between 1999 and 2009. Immunohistochemistry for p40, p63, thyroid transcription factor-1 (TTF-1; clone SPT24 and 8G7G3/1), Napsin A, Chromogranin A, Synaptophysin, and CD56 were performed. Staining intensity (weak, moderate, or strong) and distribution (focal or diffuse) were also recorded. Of all, 449 (93.5%) patients were confirmed as having squamous cell carcinomas; the cases were mostly diffusely positive for p40 and negative for TTF-1 (8G7G3/1). Twenty cases (4.2%) were reclassified as adenocarcinoma since they were positive for TTF-1 (8G7G3/1 or SPT24) with either no or focal p40 expression, and all of them were poorly-differentiated with squamoid morphology. In addition, 1 case was reclassified as adenosquamous carcinoma, 4 cases as large cell carcinoma, 4 cases as large cell neuroendocrine carcinoma, and 2 cases as small cell carcinoma. In poorly-differentiated non-small cell lung carcinomas, an accurate distinction between squamous cell carcinoma and adenocarcinoma cannot be reliably determined by morphology alone and requires immunohistochemical analysis, even in resected specimens. Our findings suggest that TTF-1 8G7G3/1 may be better suited as the primary antibody in differentiating adenocarcinoma from squamous cell carcinoma. PMID:25871623

Metastatic Basal Cell Carcinoma Accompanying Gorlin Syndrome

Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

Yang, Mi Gyoung

1994-01-01

Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients(68%) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, 82% of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients(64%). Five of eighteen patients(28%) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was 43% and the disease free survival was 31%. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation. The principal cause of death was lung metastasis(36%). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well

Basal cell carcinoma of the axilla, an area that is not usually exposed to the sun, is rare. Individuals with basal cell nevus syndrome, a disorder associated with a mutation in the patch 1 (PTCH1) gene, develop numerous basal cell carcinomas. To describe a woman with basal cell nevus syndrome who developed a pigmented basal cell carcinoma in each of her axilla and to review the features of axillary basal cell carcinoma patients with Goltz-Gorlin syndrome. Pubmed was used to search the following terms: axillary basal cell carcinoma and basal cell nevus syndrome. The papers and their citations were evaluated. Basal cell nevus syndrome patients with basal cell carcinoma of the axilla were observed in two women; this represents 2.5% (2 of 79) of the patients with axillary basal cell carcinoma. Both women had pigmented tumors that were histologically nonaggressive. The cancers did not recur after curettage or excision. Basal cell carcinoma of the axilla has only been described in 79 individuals; two of the patients were women with pigmented tumors who had basal cell nevus syndrome. Similar to other patients with axillary basal cell carcinoma, the tumors were histologically nonaggressive and did not recur following treatment. Whether PTCH1 gene mutation predisposes basal cell nevus patients to develop axillary basal cell carcinomas remains to be determined.

2016-06-01

The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

In order to investigate the effects of Quercetin on radiosensitivity of human Uterine Cervix Cancer HeLa cells, MTT assay and clonogenic assay were performed to evaluate the cytotoxicity of Quercetin on the cells. Clonogenic assay was used to observe its effects on the radiosensitivity of the cells. MTT result shows that the inhibition of Quercetin on the cells is in the dose-dependent and time-dependent. And the clonogenic assay result shows that the effect of Quercetin on HeLa cells can be divided into two parts, one for the inhibition of HeLa cells and another for the induction of HeLa cell death. The other clonogenic assay result also shows Quercetin can decrease clonogenic survival rate of HeLa cells exposed to X rays. The study shows Quercetin might enhance the radiosensitivity of the HeLa cell line. And it may provide a useful evaluation to combination of ionizing radiation and Quercetin for cancer patients.

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neoplasm that has exhibited an exponential increase in incidence in the past 3 decades. Combined MCC and cutaneous squamous cell carcinoma (SCC/MCC) is an uncommon variant of MCC that exhibits worse prognosis than pure MCC. To describe the clinical presentation, dermoscopy, and histology of an unusual subtype of combined SCC/MCC. A 73-year-old white woman presented with an ulcerated and violaceous 10-mm plaque on her right jawline that had been present for 2 to 3 months. On dermoscopy, the lesion was predominantly milky pink to red with peripheral crusting and large-caliber polymorphous vessels. Histology revealed SCC in situ above and adjacent to MCC. The tumor was excised with clear margins, and sentinel lymph node scintography was negative for nodal involvement. © The Author(s) 2016.

High-voltage irradiation of xenotransplanted human ovarial, endometrial, and cervical carcinomas

Kleine, W.; Wrzodek, W.; Stange, S.; Ladner, H.A.

1981-01-01

High-voltage irradiation of four ovarial carcinomas, four endometrial carcinomas and two carcinomas of the cervix is reported on which were transplanted subcutaneously to nu/nu mice. In all cases, the growth was stopped and the tumour receded under irradiation; in 8 cases, after stopping the irradiation with a dose of 30 to 60 Gy the growth went on. Of two carcinomas with decrease in the size and a stopped growth over 20 weeks, in one case no vital cells could be found any more while in the other one there were still numerous vital cells. These showed also after irradiation an unchanged radionucleotid incorporation in the single cell suspension. The effect of a high-voltage irradiation seems to be independent on the histologic picture, but dependent on the dose and the fractioning. The incorporation rates of 3 H-thymidine and 3 H-uridine in the single cell suspension reamined inchanged both before and after irradiation. Irradiation of the xenotransplantate of one side showed the exclusively local effect of this measure. This is confirmed by comparative examinations of the same tumours with a chemotherapy. Thus the nude mouse model offers the possibility of observing the effects of a high-voltage irradiation of human tissue in vivo without involving the total organism of the tumourous animal like in chemotherapy. This shows another field for future questions with nude mice. (orig.) [de

Anne Kristine Larsen, MD

2014-03-01

Full Text Available Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstructed with a free latissimus dorsi flap. The cosmetic result is acceptable and there is no sign of recurrence 1 year postoperatively.

Metastatic renal cell carcinoma management

Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

Merkel cell carcinoma is a rare, highly aggressive cutaneous neuroendocrine carcinoma most commonly seen in sun-damaged skin. Histologically, the tumor consists of primitive round cells with fine chromatin and numerous mitoses. Immunohistochemical stains demonstrate expression of neuroendocrine markers. In addition, cytokeratin 20 (CK20) is expressed in ∼95% of cases. In 2008, Merkel cell carcinoma was shown to be associated with a virus now known as Merkel cell polyomavirus in ∼80% of cases. Prognostic and mechanistic differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative Merkel cell carcinoma may exist. There has been the suggestion that CK20-negative Merkel cell carcinomas less frequently harbor Merkel cell polyomavirus, but a systematic investigation for Merkel cell polyomavirus incidence in CK20-negative Merkel cell carcinoma has not been done. To test the hypothesis that Merkel cell polyomavirus is less frequently associated with CK20-negative Merkel cell carcinoma, we investigated 13 CK20-negative Merkel cell carcinomas from the files of the Cleveland Clinic and the University of Michigan for the virus. The presence or absence of Merkel cell polyomavirus was determined by quantitative PCR performed for Large T and small T antigens, with sequencing of PCR products to confirm the presence of Merkel cell polyomavirus. Ten of these (77%) were negative for Merkel cell polyomavirus and three (23%) were positive for Merkel cell polyomavirus. Merkel cell polyomavirus is less common in CK20-negative Merkel cell carcinoma. Larger series and clinical follow-up may help to determine whether CK20-negative Merkel cell carcinoma is mechanistically and prognostically unique.

The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

In vitro double labeling autoradiography for measuring the labeling index, duration of S phase and potential doubling time has been used to assess the effect of a single and fractionated test dose of irradiation in uterine cervix cancer applied in 21 patients. Tumor-labeling index fell significantly in those tumors which had a high labeling index before irradiation, and these cases were found later to exhibit a good radiation response. Duration of S phase which ranged between 9 and 27 hours prior to irradiation was increased. Differences between the potential doubling time and the actual doubling time suggest a massive cell loss in tumors which were, for the most part, of exophytic type. Fractionated irradiation provides more reliable informations than a single dose and is useful for investigation of dynamic changes in the kinetics of an asynchronous cell population.

Hesperidin is a flavonoid that has various pharmacological activities including anti-inflammatory, antimicrobial and antiviral activities. The aim of the study is the isolation of hesperidin from the peel of Citrus sinensis L. (Rutaceae), and the evaluation of its antioxidant capacity and cytotoxicity against different human carcinoma cell lines. In the present work, hesperidin is identified and confirmed using chromatographic and spectral analysis. To correlate between hesperidin concentration and antioxidant capacity of peel extracts, extraction was carried out using 1% HCl-MeOH, MeOH, alkaline solution, the concentration of hesperidin determined qualitatively and quantitatively using high performance thin layer chromatography (HPTLC), high performance liquid chromatography (HPLC) analysis, in vitro antioxidant capacity of hesperidin and the extracts against free radical diphenylpicrylhydrazyl (DPPH•) performed using an electron spin resonance spectrophotometer (ESR). Cytotoxic assay against larynx, cervix, breast and liver carcinoma cell lines was performed. Hesperidin was found to be moderately active as an antioxidant agent; its capacity reached 36%. In addition, the results revealed that hesperidin exhibited pronounced anticancer activity against the selected cell lines. IC₅₀ were 1.67, 3.33, 4.17, 4.58 µg/mL, respectively. Orange peels are considered to be a cheap source for hesperidin which may be used in the pharmaceutical industry as a natural chemopreventive agent. Hesperidin and orange peel extract could possess antioxidant properties with a wide range of therapeutic applications.

Full Text Available Oral squamous cell carcinoma (OSCC is the most common epithelial malignancy affecting the oral cavity. The most common sites for the development are lateral surface of tongue and floor of mouth; the least common sites are soft palate, gingiva, and buccal mucosa. Gingival squamous cell carcinoma can mimic a multitude of oral lesions and enlargements, especially those of inflammatory origin. In addition, predisposing and presenting factors are different from those of other OSCCs. Careful examination as well as routine biopsy are crucial for accurate diagnosis.

A forty-year-old woman with a known case of carcinoma cervix underwent 18-fluorodeoxyglucose positron emission tomography.computed tomography (18-FDG PET/CT) for evaluation of abdominal lymphadenopathy. Her treatment history included radical hysterectomy and radiotherapy 6 months ago. She complained of weight loss of 7 kg over last 5 months. The maximum intensity projection (MIP) image (Fig. 1a, arrows) revealed multiple areas of intense FDG uptake, which on CT and fused PET/CT images were localized to multiple lymph nodes in bilateral cervical region, right axilla, mediastinum and abdomen. The SUVmax of right axillary lymph nodes (most FDG avid of all lymph node groups) was 15.3. There was no evidence of metabolically active disease or CT demonstrable abnormality in rest of the body. Presence of metabolically active disease in extensive supradiaphramatic lymphadenopathy was unusual for a case of carcinoma cervix. This finding, along with history of significant weight loss and absence of extranodal disease, was suspicious for unrelated pathology like lymphoproliferative disorder or granulomatous disease. Mixed malignant and benign lymphadenopathy was also considered a possibility. To solve the conundrum, 18-fluoro-L-thymidine (FLT) PET/CT was performed on the next day. This scan was performed to assess the proliferation rate in various above-mentioned lymph nodes, and to plan the optimum site of biopsy. The FLT PET scan (Fig. 1b) showed physiological distribution of the tracer in bone marrow, liver, gall bladder and urinary bladder. There was minimal FLT uptake in the enlarged, FDG avid lymph nodes (Fig. 1c and d). SUVmax of FLT uptake in right axillary lymph nodes was 1.4 (SUVmax of FDG uptake = 15.8). The SUVmax of FLT uptake in cervical, mediastinal and abdominal lymph nodes were 1.3, 1.4 and 1.0 respectively. (SUVmax of FDG uptake 12.1, 12.7 and 11.9, respectively). Considering avidity for FDG and non-avidity of proliferation marker tracer (FLT), possibility of

Purpose: To establish the magnitude of brachytherapy dose reduction required for stage IIB and III carcinoma cervix patients treated by external radiation and medium dose rate (MDR) brachytherapy at a dose rate of 220±10 cGy/h at point A.Materials and methods: In study-I, at the time of MDR brachytherapy application at a dose rate of 220±10 cGy/h at point A, patients received either 3060 cGy, a 12.5% dose reduction (MDR-12.5), or 2450 cGy, a 30% dose reduction (MDR-30), to point A and they were compared to a group of previously treated LDR patients who received 3500 cGy to point A at a dose rate of 55-65 cGy/h. Study-II was a prospective randomized trial and patients received either 2450 cGy, a 30% dose reduction (MDR-II (30)) or 2800 cGy, a 20% dose reduction (MDR-II (20)), at point A. Patients were evaluated for local control of disease and morbidity. Results: In study-I the 5-year actuarial local control rate in the MDR-30 and MDR-12.5 groups was 71.7±10% and 70.5±10%, respectively, compared to 63.4±10% in the LDR group. However, the actuarial morbidity (all grades) in the MDR-12.5 group was 58.5±14% as against 34.9±9% in the LDR group (P 3 developed complication as against 62.5% of those receiving a rectal BED of (140 3 (χ 2 =46.43; P<0.001). Conclusion: We suggest that at a dose rate of 220±10 cGy/h at point A the brachytherapy dose reduction factor should be around 30%, as suggested by radiobiological data, to keep the morbidity as low as possible without compromising the local control rates.

Since its introduction in clinical practice in the 1990 s, positron emission tomography (PET), usually with 18 F-fluoro-2-deoxy-D-glucose ( 18 F-F.D.G.), has become an important imaging modality in patients with cancer. For cervix carcinoma, F.D.G.-PET is significantly more accurate than computed tomography (CT) and is recommended for loco-regional lymph node and extra pelvic staging. The metabolic dimension of the technique provides additional prognostic information. Ongoing studies now concentrate on more advanced clinical applications, such as the planning of radiotherapy, the response evaluation after the induction of therapy, the early detection of recurrence. Technical innovations, such as PET cameras with better spatial resolution and hybrid positron emission tomography/computed tomography (PET-CT), available now on the whole territory, provide both anatomic and metabolic information in the same procedure. From the point of view of biological metabolism, new radiopharmaceutical probes are being developed. Those hold promise for future refinements in this field. This article reviews the current applications of F.D.G.-PET in patients with cervix cancer. (authors)

Merkel cell carcinoma is believed to be derived from Merkel cells after infection by Merkel cell polyomavirus (MCPyV) and other poorly understood events. Transcriptional profiling using cDNA microarrays was performed on cells from MCPy-negative and MCPy-positive Merkel cell carcinomas and isolated normal Merkel cells. This microarray revealed numerous significantly upregulated genes and some downregulated genes. The extensive list of genes that were identified in these experiments provides a large body of potentially valuable information of Merkel cell carcinoma carcinogenesis and could represent a source of potential targets for cancer therapy. © 2014 John Wiley & Sons A/S.

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

Squamous cell carcinoma of the breast: a case report

Full Text Available Abstract Background Squamous cells are normally not found inside the breast, so a primary squamous cell carcinoma of the breast is an exceptional phenomenon. There is a possible explanation for these findings. Case presentation A 72-year-old woman presented with a breast abnormality suspected for breast carcinoma. After the operation the pathological examination revealed a primary squamous cell carcinoma of the breast. Conclusion The presentation of squamous cell carcinoma could be similar to that of an adenocarcinoma. However, a squamous cell carcinoma of the breast could also develop from a complicated breast cyst or abscess. Therefore, pathological examination of these apparent benign abnormalities is mandatory.

Nevoid Basal Cell Carcinoma Syndrome (Gorlin Syndrome).

Science.gov (United States)

Bresler, Scott C; Padwa, Bonnie L; Granter, Scott R

2016-06-01

Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

Fifteen patients with advanced or recurrent squamous-cell carcinoma of the cervix, vulva, vagina, and urethra were treated with simultaneous combination chemotherapy (5-fluorouracil infusion and mitomycin C) and radiotherapy (3,000 rad for a period of three weeks). Three to four weeks after completion of radiotherapy, 13 of 15 patients achieved partial or complete tumor shrinkage. Nine of 15 patients are alive, eight of whom (at a median follow-up time of 24 months) have no evidence of disease. The longest survival time was 45 + months. There was minimal toxicity associated with this therapy. The results of this pilot study suggest that the simultaneous administration of radiation and chemotherapy is an effective method of treatment of advanced female genital tract carcinoma

Differentiation is a major histological parameter determining tumor aggressiveness and prognosis of the patient; cancer stem cells with their slow dividing and undifferentiated nature might be one of the factors determining the same. This study aims to correlate cancer stem cell markers (CD44 and CD147) with tumor differentiation and evaluate their subsequent effect on prognosis. Immunohistochemical analysis in treatment naïve oral cancer patients (n = 53) indicated that the expression of CD147 was associated with poorly differentiated squamous cell carcinoma and moderately differentiated squamous cell carcinoma (p squamous cell carcinoma and poorly differentiated squamous cell carcinoma patients were CD44 high /CD147 high as compared to only 10% of patients with well-differentiated squamous cell carcinoma. A three-way analysis indicated that differentiation correlated with recurrence and survival (p oral squamous cell carcinoma cell lines originating from different grades of oral cancer. Flowcytometry-based analysis indicated an increase in CD44 + /CD147 + cells in cell lines of poorly differentiated squamous cell carcinoma (94.35 ± 1.14%, p squamous cell carcinoma origin (93.49 ± 0.47%, p squamous cell carcinoma origin (23.12% ± 0.49%). Expression profiling indicated higher expression of cancer stem cell and epithelial-mesenchymal transition markers in SCC029B (poorly differentiated squamous cell carcinoma originated; p ≤ 0.001), which was further translated into increased spheroid formation, migration, and invasion (p squamous cell carcinoma origin. This study suggests that CD44 and CD147 together improve the prognostic efficacy of tumor differentiation; in vitro results further point out that these markers might be determinant of differentiation characteristics, imparting properties of increased self-renewal, migration, and invasion.

47 out of 56 cases of intact uterine cervix cancer treated by radiation at the Hanyang University Hospital were followed 18 months or more after treatment. (7 patients died before 18 months, 2 cases lost to follow-up). Age distribution reveal 5 cases in 30's, 18 cases in 40's, 17 cases in 50's, 7 cases in 60's. Histologically, all cases were squamous cell type except one case of adenocarcinoma. 1. 45 cases were treated by combined external Co-60 irradiation and intracavitary irradiation by Cs-137 small sources. 1 case was treated by external irradiation only, and 1 case by intracavitary only. 2. Rectal injuries were observed in 13 cased (27.6%), 4 cases in Grade 1, 8 cased in Grade 2 and 1 cases in Grade 3 which needed surgical management. 3. Average intervals of rectal injury and point A dose reveal 6 cases between 7000-7999 rad and 6 cases between 8000-8999 rad and 1 case above 9000 rad. Even though there is no direct relation between point A dose and rectal injury, it is expected that rectal injury increases as point A dose increase. 4. In the normal condition, rectal injury can't be attributed to one major cause. Radiation dose, small source distribution, general condition of patients, local anatomy of the individual patient, history of PID and previous surgery, all play complex roles

Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

Full Text Available Cervical cancer is the second most common cancer in women. Neoadjuvant chemotherapy for patients with locally advanced cervix cancer has comparable benefits to concurrent chemoradiotherapy (CCRT, but with fewer side effects. This systematic review aims to provide a comprehensive summary of the benefits of neoadjuvant chemotherapy for the management of locally advanced cervix cancer from stage IB2 (tumor >4.0 cm to IIIB (tumor extending to the pelvic wall and/or hydronephrosis. Our primary objective was to assess benefits in terms of survival. The data source included the USA national library of medicine, Medline search, and the National Cancer Institute PDQ Clinical Protocols. Inclusion criteria for consideration in the current systematic review included studies published between January 1997 and December 2012. In terms of histology, they had to be focused on squamous cell carcinoma, adenosquamous carcinoma, and/or adenocarcinoma. Patients should be either chemotherapy naïve or cervix cancer chemotherapy naïve, and have a performance status ≤2. The search in the above-mentioned scientific websites led to identify 49 publications, 19 of which were excluded, as they did not meet the inclusion criteria of this systematic review. Therefore only 30 studies were deemed eligible. Data was collected from 1760 patients enrolled in the current systematic review study. The mean age was 45.2 years. The mean tumor size was 4.7 cm. The most commonly used chemotherapies were cisplatin doublets. Paclitaxel was the most commonly used chemotherapeutic agent in the doublets. The mean chemotherapy cycles were 2.7. After chemotherapy, patients underwent surgery after a mean time of 2.5 weeks. The standard operation was radical hysterectomy with pelvic lymphadenectomy. Chemotherapy achieved an objective response rate of 84%. The 5-year progression-free survival and overall survival were 61.9% and 72.8% respectively. The treatment protocol was associated

1988-01-01

From May 1979 through December 1981, a total of 530 patients with carcinoma of the uterine cervix were treated with radiation therapy with curative intent. Of the 530 patients, 365 were treated with a high-dose-rate remote-controlled afterloading system (RALS) using a cobalt source, and 165 patients received a low dose rate using a radium source. External pelvic irradiation with a total of 40-50 Gy to the whole pelvis followed by intracavitary radiation (ICR) with a total dose of 30-39 Gy in ten to 13 fractions to point A was the treatment protocol. ICR was given three times a week with a dose of 3 Gy per fraction. Five-year actuarial survival rate with high-dose-rate ICR by stage was as follows: stage I:82.7% (N = 19) stage II:69.6% (N = 184), and stage III:52.2% (N = 156). The above results were comparable with those with conventional low-dose-rate ICR treatment, and late complications were far less. The application of high-dose-rate ICR was technically simple and easily performed on an outpatient basis without anesthesia, and the patients tolerated it very well. Radiation exposure to personnel was virtually none as compared with that of low-dose-rate ICR. Within a given period of time, more patients can be treated with high-dose-rate ICR because of the short treatment time. The authors therefore conclude that high-dose-rate ICR is suitable for a cancer center where a large number of patients are to be treated

1989-01-01

In vitro modulation of spontaneous cell mediated cytotoxicity by interferon and interleukin 2 was carried out using peripheral blood lymphocytes from patients with cancer of the uterine cervix before and at different intervals after commencement of radiation treatment. A total of 150 patients with various stages of the disease were included and cytotoxicity was measured using the single cell cytotoxic assay. These results indicate a beneficial effect in vitro of interleukin 2 and interferon in augmenting spontaneous cell mediated cytotoxicity, a possibly vital antitumour immune mechanism in patients with relatively early cervix cancer. Natural killer cell, lymphokine activated killer cell and interferon activated killer cell activity was depressed immediately following radiotherapy. The activity of these cell types later on increased above pretreatment levels in patients with stages I, IIA and IIB. A similar rebound above pretreatment levels was not observed in patients with stages III and IV. (orig.)

Radiation biologists have classified radiation-induced cell death based on cell proliferative capacity to either mitotic or interphase death. Cytologists have revealed two morphologically and biochemically diverse forms of cell death, apoptosis and necrosis. While the knowledge of the former is already well exploited by radiologists, cell susceptibility to apoptosis and necrosis is still under investigation. We studied characteristics of spontaneous cell death, and dose dependence and time course of radiation-induced cell death of human uterine cervix epitheloid carcinoma HeLaS 3 in culture. Cells were irradiated with 2-40 Gy of γ-rays. The effect on growth, viability, morphology and genomic DNA structure were followed 24-72 h after irradiation. Cell viability was evaluated by trypan-blue exclusion assay and cell morphology by in situ DNA staining with propidium iodide. Cell genomic DNA fragmentation pattern was determined by electrophoresis on 2% agarose gels. At all cell densities 25-35% cells were PI positive and their DNA was fragmented to a high molecular size (≥20 kbp), but the internucleosomal ladder was not observed. A significant decrease in viability to 33% was observed 72 h post 40 Gy irradiation. It corresponded to 55% of PI positive cells. A smear of smaller DNA fragments (0.1-1 kbp), 24 h after 10-20 Gy irradiation was considered as proof that the dominant form of radiation-induced cell death was necrosis. It was concluded that the dominant form of radiation-induced cell death in HeLaS 3 population was necrosis and the radiation dose which caused 50% of cell death after 72 h (termed ND 50 ) was between 30-40 Gy.

Full Text Available Background: Development of skin neoplasms is one of the most important chronic complications of radiation therapy. Basal cell carcinoma (BCC is the most frequent carcinoma occurring at the region of the body to which radiotherapy was delivered. Aim: The aim of this study was to evaluate clinical and histological aspects of basal cell carcinoma in patients with a history of radiotherapy. Materials and Methods: Medical records and microscopic slides of 80 patients with basal cell carcinoma who had received radiotherapy (1996-2006 were reviewed in pathology department of Imam Reza hospital of Mashhad, Iran. Collected data were analyzed statistically using descriptive test. Results: 60 men and 20 women were included, majority of them in their sixties. Plaque was the most common clinical pattern of basal cell carcinoma. Fifty one percent of the patients had pigmented and 42.5% had multiple lesions. Scalp was the most common site of involvement. Histologically, macronodular and pigmented carcinoma were the most predominant forms of basal cell carcinoma. Discussion: Majority of patients had scalp involvement and multiple lesions. Nodular and pigmented forms were the most common histological findings. We suggest the need for close supervision in patients with a history of radio therapy in the past.

Cutaneous squamous and neuroendocrine carcinoma: genetically and immunohistochemically different from Merkel cell carcinoma.

Cutaneous neuroendocrine (Merkel cell) carcinoma most often arises de novo in the background of a clonally integrated virus, the Merkel cell polyomavirus, and is notable for positive expression of retinoblastoma 1 (RB1) protein and low expression of p53 compared with the rare Merkel cell polyomavirus-negative Merkel cell carcinomas. Combined squamous and Merkel cell tumors are consistently negative for Merkel cell polyomavirus. Little is known about their immunophenotypic or molecular profile. Herein, we studied 10 combined cutaneous squamous cell and neuroendocrine carcinomas for immunohistochemical expression of p53, retinoblastoma 1 protein, neurofilament, p63, and cytokeratin 20 (CK20). We compared mutation profiles of five combined Merkel cell carcinomas and seven 'pure' Merkel cell carcinomas using targeted next-generation sequencing. Combined tumors were from the head, trunk, and leg of Caucasian males and one female aged 52-89. All cases were highly p53- and p63-positive and neurofilament-negative in the squamous component, whereas RB1-negative in both components. Eight out of 10 were p53-positive, 3/10 p63-positive, and 3/10 focally neurofilament-positive in the neuroendocrine component. Six out of 10 were CK20-positive in any part. By next-generation sequencing, combined tumors were highly mutated, with an average of 48 mutations per megabase compared with pure tumors, which showed 1.25 mutations per megabase. RB1 and p53 mutations were identified in all five combined tumors. Combined tumors represent an immunophenotypically and genetically distinct variant of primary cutaneous neuroendocrine carcinomas, notable for a highly mutated genetic profile, significant p53 expression and/or mutation, absent RB1 expression in the context of increased RB1 mutation, and minimal neurofilament expression.

Loss of Progesterone Receptor-Mediated Actions Induce Preterm Cellular and Structural Remodeling of the Cervix and Premature Birth

A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or ovariectomized on day 17 postbreeding. As expected, controls given vehicle delivered at term while rats delivered preterm after progesterone receptor antagonist treatment or ovariectomy. Similar to the cervix before term, the preterm cervix of progesterone receptor antagonist-treated rats was characterized by reduced cell nuclei density, decreased collagen content and structure, as well as a greater presence of macrophages per unit area. Thus, loss of nuclear progesterone receptor-mediated actions promoted structural remodeling of the cervix, increased census of resident macrophages, and preterm birth much like that found in the cervix at term. In contrast to the progesterone receptor antagonist-induced advance in characteristics associated with remodeling, ovariectomy-induced loss of systemic progesterone did not affect hypertrophy, extracellular collagen, or macrophage numbers in the cervix. Thus, the structure and macrophage census in the cervix appear sufficient for premature ripening and birth to occur well before term. With progesterone receptors predominantly localized on cells other than macrophages, the findings suggest that interactions between cells may facilitate the loss of progesterone receptor-mediated actions as part of a final common mechanism that remodels the cervix in certain etiologies of preterm and with parturition at term.

Although cervical pregnancy and placenta previa, in which the embryo and placenta embed in or adjacent to the cervix, are life-threatening complications that result in massive bleeding and poor pregnancy outcomes in women, the incidence of these aberrant conditions is uncommon. We hypothesized that a local molecular mechanism is normally in place to prevent embryo implantation in the cervix. The ovarian hormones progesterone (P(4)) and estrogen differentially direct differentiation and proliferation of endometrial cells, which confers the receptive state for implantation: P(4) dominance causes differentiation of the luminal epithelium but increases stromal cell proliferation in preparation of the uterus for implantation. In search for the cause of cervical nonresponsiveness to implantation, we found that the statuses of cell proliferation and differentiation between the uterus and cervix during early pregnancy are remarkably disparate under identical endocrine milieu in both mice and humans. We also found that cervical levels of progesterone receptor (PR) protein are low compared with uterine levels during this period, and the low PR protein levels are attributed to elevated levels of microRNA(miR)-200a in the cervix. These changes were associated with up-regulation of the P(4)-metabolizing enzyme 20α-hydroxysteroid dehydrogenase (200α-HSD) and down-regulation of its transcriptional repressor signal transducer and activator of transcription 5 in the cervix. The results provide evidence that elevated levels of miR-200a lead to down-regulation of P(4)-PR signaling and up-regulation of (200α-HSD) in the cervix, rendering it nonresponsive to implantation. These findings may point toward not only the physiological but also the pathological basis of the cervical milieu in embryo implantation.

Full Text Available BACKGROUND: A new virus called the Merkel Cell Polyomavirus (MCPyV has recently been found in Merkel Cell Carcinoma (MCC. MCC is a rare aggressive small cell neuroendocrine carcinoma primarily derived from the skin, morphologically indistinguishable from small cell lung carcinoma (SCLC. So far the actual presence of the virus in MCC tumour cells on a morphological level has not been demonstrated, and the presence of MCPyV in other small cell neuroendocrine carcinomas has not been studied yet. METHODOLOGY/PRINCIPAL FINDINGS: We investigated MCC tissue samples from five patients and SCLCs from ten patients for the presence of MCPyV-DNA by PCR and sequencing. Electron microscopy was used to search ultrastructurally for morphological presence of the virus in MCPyV-DNA positive samples. MCPyV was detected in two out of five primary MCCs. In one MCC patient MCPyV-DNA was detected in the primary tumour as well as in the metastasis, strongly suggesting integration of MCPyV in the cellular DNA of the tumour in this patient. In the primary MCC of another patient viral particles in tumour cell nuclei and cytoplasm were identified by electron microscopy, indicating active viral replication in the tumour cells. In none of the SCLCs MCPyV-DNA was detected. CONCLUSIONS/SIGNIFICANCE: Our results strongly suggest that MCPyV is an oncogenic polyomavirus in humans, and is potentially causally related to the development of MCC but not to the morphological similar SCLC.

Full Text Available Two kinds of different malignant tumors occurring within the same organ is defined as collision tumor. Small Cell Carcinoma (SmCC is high-grade derived from neuroendocrine cell tumors, occurance in the head and neck is rare. Squamous Cell Carcinoma (SCC is the most common malignancies encountered in head and neck area, but the occuranceof collision tumor is very rare. This report describe a 82 year-old woman patient with a SmCC and SCC that occurred in the maxillary sinus. CT was performed including with enhancement, MRI examination was T1WI, STIR and contrast enhancement. We also conducted analysis of Dynamic Contrast Enhancement (DCE. Histopathologic examination revealed small cell carcinoma. A distant metastasis was not detected. After patient received chemoradiotherapy (CCRT, most of  tumorwas reduced although a part of the tumor was remained. Pathological examination of surgery tumor specimen revealed that specimen consisted of SCC and SmCC was disappeared, and six months after surgery, the patient suffered tumor recurrence and multiple metastasis to the organs in the abdomen. This time we have to report that the experience one cases that are considered collision cancer of SmCC and SCC that occurred in the maxillary sinus.

Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least three subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

Origin of clear cell carcinoma: nature or nurture?

A rare but serious complication of endometriosis is the development of carcinoma, and clear cell and endometrioid carcinomas of the ovary are the two most common malignancies which arise from endometriosis. They are distinct diseases, characterized by unique morphologies, immunohistochemical profiles, and responses to treatment. However, both arise in endometriosis and can share common mutations. The overlapping mutational profiles of clear cell and endometrioid carcinomas suggest that their varied histologies may be due to a different cell of origin which gives rise to each type of cancer. Cochrane and colleagues address this question in a recent article in this journal. They show that a marker of ovarian clear cell carcinoma, cystathionine gamma lyase, is expressed in ciliated cells. Similarly, they show that markers of secretory cells (estrogen receptor and methylenetetrahydrofolate dehydrogenase 1) are expressed in ovarian endometrioid carcinoma. Taken together, they suggest that endometrioid and clear cell carcinomas arise from cells related to secretory and ciliated cells, respectively. We discuss Cochrane et al's work in the context of other efforts to determine the cell of origin of gynecological malignancies, with an emphasis on recent developments and challenges unique to the area. These limitations complicate our interpretation of tumor differentiation; does it reflect nature imposed by a specific cell of origin or nurture, by either mutation(s) or environment?

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

Although emerging evidence demonstrates increased circulating endothelial progenitor cells in patients with solid tumors, to our knowledge it is still unknown whether such cells can be cultured from patients with highly angiogenic renal cell carcinoma. We cultured and characterized circulating endothelial progenitor cells from patients with renal cell carcinoma. The circulating endothelial progenitor cell level (percent of CD45(-)CD34(+) VEGF-R2(+) cells in total peripheral blood mononuclear cells) was quantified in 47 patients with renal cell carcinoma and 40 healthy controls. Peripheral blood mononuclear cells were then isolated from 33 patients with renal cell carcinoma and 30 healthy controls to culture and characterize circulating endothelial progenitor cells. The circulating endothelial progenitor cell level was significantly higher in patients with renal cell carcinoma than in healthy controls (0.276% vs 0.086%, p cells first emerged significantly earlier in patient than in control preparations (6.72 vs 14.67 days, p culture success rate (87.8% vs 40.0% of participants) and the number of colonies (10.06 vs 1.83) were significantly greater for patients than for controls (each p cell level correlated positively with the number of patient colonies (r = 0.762, p Cells cultured from patients and controls showed a similar growth pattern, immunophenotype, ability to uptake Ac-LDL and bind lectin, and form capillary tubes in vitro. However, significantly more VEGF-R2(+) circulating endothelial progenitor cells were found in preparations from patients with renal cell carcinoma than from healthy controls (21.1% vs 13.4%, p cell colonies, a higher cell culture success rate and more colonies were found for patients with renal cell carcinoma than for healthy controls. Results indicate the important significance of VEGF-R2(+) circulating endothelial progenitors in patients with renal cell carcinoma.

Adenocarcinoma is the second most frequent cancer of the uterine cervix after squamous carcinoma, and the most frequent histotype is the mucinous one. Endo-cervical adenocarcinoma accounts for about 10–30% of all cervical cancers and clinically the lesion can be asymptomatic or, more frequently, presenting with anomalous bleeding and/or vaginal discharge. A 41-year-old woman with a diagnosis of adenocarcinoma of the uterine cervix was subjected to chemotherapy after radical surgery. During the follow-up, the patient underwent a Positron Emission Tomography integrated with Computed Tomography and pelvic Magnetic Resonance, which showed rapid and diffuse disease progression from the site of the lesion to the pelvic bones. Bone involvement in patients with cervical cancer, being a rare event, is significant since it greatly reduces life expectancy. The majority of metastatic bone lesions in cervical cancer seem to be of osteolytic nature. In our patient, Positron Emission Tomography integrated with Computed Tomography and Magnetic Resonance were the imaging methods used during the follow-up and both techniques clearly showed diffuse and rapid tumour spread to the bones

West Africa has one of the highest incidence rates of carcinoma of the cervix in the world. The vast majority of women do not have access to screening or disease treatment, leading to presentation at advanced stages and to high mortality rates. Compounding this problem is the lack of radiation treatment facilities in Senegal and many other parts of the African continent. Senegal, a country of 13 million people, had a single 60 Co teletherapy unit before our involvement and no brachytherapy capabilities. Radiating Hope, a nonprofit organization whose mission is to provide radiation therapy equipment to countries in the developing world, provided a high-dose-rate afterloading unit to the cancer center for curative cervical cancer treatment. Here we describe the implementation of high-dose-rate brachytherapy in Senegal requiring a nonstandard fractionation schedule and a novel treatment planning approach as a possible blueprint to providing this technology to other developing countries

A retrospective analysis of late rectal and recto-sigmoid complications was carried out of the 203 patients with stage III B carcinoma of uterine cervix, treated using radiation therapy alone during January 1979 to December 1983. The patients were treated with a combination of external irradiation and single intracavitary insertion. External irradiation was randomised to one of the four different fractionation regimes having dose per fraction of 2 Gy, 3 Gy, 4 Gy and 5.4 Gy, delivering with five fractions/week, three fractions/week, two fractions/week and one fraction/week, respectively. The total doses in four different regimens were adjusted using the TDF model. There were 39 cases of late radiation induced rectal and recto-sigmoid complications. The complication rate was correlated with the dose per fraction and TDFs delivered in each regimen. The complication rate of 8.2% for 2 Gy per fraction was increased to 33.33% for 5.4 Gy per fraction. It was found that there is strong correlation (P [de

2006-06-01

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.

The Kumar Cervical Applicator minimizes patient discomfort and improves patient mobility while reducing the tendency of the applicator to rotate during the 40 to 50 hours of uterine intracavitary endocurietherapy. Patients with previously untreated invasive carcinoma of the uterine cervix, F.I.G.O. stages IB-IVA, were treated with two Kumar intracavitary endocurietherapy (ECT) applications of 2,500 rad each to point ''A,'' and 4,000 rad external-beam radiotherapy (EXRT) to midplane, for a total dose of 9,000 rad. The major complication rate was 2.7 %, and the local control rate was 85 % (22/26 patients) for stage I and II, and 91 % (10/11 patients) for stage III and IVA. (author)
