Sample records for uterine cervical erosion

  1. Intravascular interventional therapy for uterine cervical adenocarcinoma

    International Nuclear Information System (INIS)

    Adenocarcinoma of the uterine cervix shows an upward trend in younger patients with poorer prognosis in comparing with squamous carcinoma. The traditional radiotherapy and intravenous route chemo- therapy are all difficult in treating uterine cervical adenocarcinoma due to different biomolecular characterization with that of the squamous cell carcinoma. Because of long term growth for primary lesion and infiltration with limitation inside the pelvis, provides a reliable clinico-pathologic basis for intra-vascular interventional treatment. This article presents a comprehensive statement of clinico-pathologic, biomolecular investigation and intravascular intervention for uterine cervical carcinoma. (authors)

  2. Uterine artery chemoembolization: its application in treating cervical pregnancy

    International Nuclear Information System (INIS)

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in the treatment of cervical pregnancy. Methods: During the period of Sep. 2005-Dec. 2007, uterine artery chemoemboliztion was performed in 12 patients with cervical pregnancy in the authors' hospital. Via bilateral uterine arteries 100 mg MTX and 80,000 U Gentamycin were infused separately, after that the bilateral uterine arteries were embolized with gelfoam. Cleaning of the uterus and the cervix uteri was carried out in 24 -72 h after the procedure. Results: The technical success rate of bilateral uterine artery chemoembolization was 100%. The blood loss was 50-100 ml (mean 65 ml) during the procedure of cleaning the uterus and the cervix uteri. No serious complications occurred. Conclusion: Uterine artery chemoembolization is an effective and safe treatment for cervical pregnancy, which can greatly avoid unnecessary uterectomy and preserve fertility function. (authors)

    Preoperative uterine artery embolization and cervical evacuation as conservative management of cervical pregnancy has been tried in recent years. However, cervical suturing, vasoconstrictor injection, or cervical ballooning was frequently used as an ancillary measures in those procedures in most of the previous studies. We report two cases of cervical pregnancy that were successfully treated with preoperative uterine artery embolization and removal of gestational material without ancillary pr...

    Cervical ectopic pregnancy is associated with high risk for massive bleeding conditions. Cervical ectopic pregnancy can usually be treated by methotrexate injection or surgery. We present 4 cases of cervical ectopic pregnancy that were treated successfully with different uterine-conserving methods. By comparing our experience of 4 cases managed in different ways, we found that laparoscopic uterine artery occlusion before cervical curettage is more effective method for preventing massive bleeding.

  6. Pharmacokinetics of adriamycin vaginal suppository on uterine cervical cancer

    International Nuclear Information System (INIS)

    Vaginal suppositories of Adriamycin (ADM, 5 mg), for reducing the capacity for repair from sublethal damage of X-ray-irradiated cells, were prepared using Wipepsol S-55 as the vehicle, and were intravaginally administered to patients with advanced uterine cervical cancer, and their pharmacokinetics and clinical effects were studied. The ADM concentration in the uterine cervical cancer tissues indicated high levels (17 to 566 ?g/g), and migration into the cardinal ligament and regional lymph nodes was noted. However, little ADM was detected in serum (0 to 0.14 ?g/g), probably because of its molecular weight and excellent tissue absorbance, and no side effects, such as cardiotoxicity and myelosuppression due to consecutive administration were detected. Histologically, the effect obtained when administered alone was limited, administration in combination with radiotherapy being more effective. Accordingly, radiotherapy of advanced uterine cervical cancer with concomitant administration of ADM vaginal suppositories seems to bring about a more powerful antitumoral effect with fewer systemic side effects.

    2013-12-15

    The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

  8. Clinical evaluation of postoperative radiotherapy for uterine cervical cancer

    International Nuclear Information System (INIS)

    Prognostic factors were reviewed in ninety-seven patients who underwent postoperative radiotherapy for uterine cervical cancer. All were treated by radical hysterectomy and pelvic lymphadenectomy. Indications for adjuvant radiotherapy included pelvic lymph node metastases, parametrial infiltration, vascular space involvement, a very close surgical margin, large primary lesion, adenocarcinoma/adenosquamous cell carcinoma, and uninvolved cervical tissue less than 3 mm. They were given 6 MV X ray to the whole pelvic space (ninety-three cases treated with center split). The total dose was 30-60 Gy, and four received intracavitary irradiation. Thirty-seven patients were in clinical stage Ib, fifteen were in IIa, and forty-five were in IIb. The five-year survival rate was 80.4%, 78.8%, 84.1% and the overall rate was 81.5%. There were twenty-five recurrences, four recurrences at local sites, fifteen at distant, and six at both. Of the recurrences, 60% were evident within 2 years, and the one-year survival rate from recurrences was 50%, which was comparatively good. As mentioned, postoperative radiotherapy for uterine cervical cancer appears to be effective. The prognostic factors included the number of pregnancy, abortion, histologic type, parametrial infiltration, and pelvic lymph node metastases. Those with these prognostic factors were in the high risk group. It is necessary for those in the high risk group to receive some adjuvant therapy, such as chemotherapy. (author)

  9. Second cancer after radiotherapy of the uterine cervical cancer

    International Nuclear Information System (INIS)

    To study the relative risk of second cancer after radiotherapy, we reviewed 2465 cases of uterine cervical cancer who were treated in our institute from 1962 to 1986 and were followed up for more than 5 years. Among them, 1502 cases were treated by radiotherapy with or without surgery (radiotherapy group), and the remainder were treated by surgery only (surgery only group). We defined second cancer as malignancy that occurred in another organ after an interval of 5 years or more from the end of treatment of the first cancer. The relative risk of second cancer was computed by the person-year method advocated by Schoenberg. Second cancer was observed among 8 cases of the surgery group, whereas 43 cases were observed among the radiotherapy group. The cases were: rectal cancer, 6 cases; bladder cancer, 4 cases. The observed and expected ratio (O/E ratio) was 4.02 in rectal cancer and 7.98 in bladder cancer. This incidence of the both cancers was significantly high in the radiotherapy group. Three of the 6 cases with rectal cancer underwent operation in our institute. The incubation periods between the first and second cancers were from 9 to 21 years. Each case exhibited symptoms of chronic radiation proctitis after radiotherapy for uterine cervical cancer. It is thought necessary to follow up such cases carefully to detect radiation induced cancer. (author)

  10. Histological study on radiosensitivity of uterine cervical cancer

    International Nuclear Information System (INIS)

    Primary lesions in 80 cases of uterine cervical cancer were experimentally irradiated with 1000 R of telecobalt, and after 7 days, evaluation of their sensitivity was done. Since histological study of a given dose in a given period is indispensable, the dose of 1000 R and evaluation on the 7th day is clinically useful. A considerable correlation was noted between the level of sensitivity evaluated on the basis of our conventional histological criteria and the prognosis. But on the other hand, some gap was noted and an explanation for this was sought. The relationship between the interstitial reactions and the sensitivity was studied in 50 cases with uterine cervical cancer. In the high-sensitivity group, an abundant formation of granulation with numerous capillaries and a variety of acute exudative inflammations were found, and the lesion in the cancer nest showed a change, a so-called acute necrotic inflammation. Histological criteria for radiosensitivity were established by considering changes in both the parenchyma and stroma of the tumor, as mentioned above. Namely, the change in the parenchyma of the tumor considered to have good sensitivity are as follows: a) swelling and degeneration of the cancer cells are marked and diffuse, b) cancer nest shows the significant decrease in size, and c) viable cells and normal mitosis are few in the fundus of the cancer nest, etc. On the other hand, the changes of the stroma of the tumor are as follows: a) a large number of neutrocytes, acidocytes, histocytes and mast cells are recognized, b) plenty of capillaries exist and fresh reticular granulations are found, and c) destruction of the fundus of the cancer nest and differentiation of the cancer nest are marked, etc. (S.

  12. Results of Radiation Therapy in Stage III Uterine Cervical Cancer

    International Nuclear Information System (INIS)

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no significances of 5 year survival rate by total radiation doses and external radiation doses (40 Gy vs 50 Gy) of whole or true pelvis in stage IIIa and IIIb(P=NS). Treatment failures rates were 40.3%(29 patients) in stage IIIa and 57.4%(89 patients) in stage IIIb, 17 patients (23.6%) in stage IIIa and 46 patients (29.7%) in stage IIIb experienced complications. Total radiation doses more than 85 Gy produced serious complication in both stage IIIa(50%) and Iib(50%), Serious complication rates were higher in group received external radiation doses of 50 Gy than 40 Gy to whole or true pelvis in stage IIIa and IIIb. Serious rectal complication developed in rectal doses more than 65 Gy, and serious bladder complication developed in bladder doses more than 75 Gy. Major cause of death was cachexia due to locoregional failure in both stage IIIa(34.7%) and IIIb(43.9%). Conclusion : From this study, we found that external radiation therapy with ICR was found to have a tendency to be superior to external radiation therapy alone in survival rate, local control rate and complication rate but not different in statistics, and external radiation doses of 50 Gy than 40 Gy tho whole or true pelvis produced serious rectal and bladder complications in stage III uterine cervical cancer

  14. Postirradiation sarcoma (malignant fibrous histiocytoma) following uterine cervical cancer

    International Nuclear Information System (INIS)

    A case of postirradiation sarcoma, a malignant fibrous histiocytoma, is described. The tumor occurred in the radiation field (the buttock) 8 years after radiation therapy for keratinizing squamous cell carcinoma of the uterine cervix. The 68-year-old female patient with the inital diagnosis of cervical cancer was treated with pelvic irradiation in 1973. She did well after that with no evidence of disease until 1981 when she developed an enlarging mass in the right buttock within the field of the previous radiation therapy. Microscopically, the tumor at biopsy was composed of pleomorphic histiocyte-like cells, spindle-sphaped cells arranged in a storiform pattern and multinucleated giant cells with bizarre nuclei. Cytodiagnostically, two types of cells, fibroblast-like cells ane histiocyte-like cells, were found. And some cells were considered to be transitional forms, intermediate between fibroblast and histiocytes. Multinucleated pleomorphic giant cells were sometimes seen. Ultrastructurally, the same types of cells were confirmed. These cells contained large numbers of rough endoplasmic reticula with dilated lumens, vacuoles, lysosomal structures, and lipid droplets.

  15. Results of irradiation therapy for advanced uterine cervical cancer

    International Nuclear Information System (INIS)

    152 patients with advanced uterine cervical cancer (76 in stage III, 47 in stage IV and 29 in recurrence) were treated at Miyagi Seijinbyo Center in fifteen years (1967-1981). Our standard treatment was a combined therapy of 6 MVX ray whole pelvis irradiation and intracavitary radium irradiation (or simple total hysterectomy) The actuarial 5-year-survival rate was 46.0% in stage III, 9.4% in stage IV and 10.3% in recurrence. In stage III, the actuarial 5-year-survival rate in nine cases with external irradiation alone was (22.2%), in 44 cases with intracavitary irradiation and external irradiation 48.7%; in 14 cases with operation and external irradiation 57.1%. No five year survival was found in nine interrupted-irradation cases. Moderate complications in the rectum and/or the urinary bladder were found in eight of 67 (12%) irradiation-completed patients in stage III. Five 5-year-survival cases (two in stage IV and three in recurrence) were reported. (author)

  16. A study on prognostic factors of uterine cervical cancer

    International Nuclear Information System (INIS)

    Prognostic factors of cancer of the cervix were studied in 286 cases treated by radiotherapy. The four items started below relating to morphological characteristics and found to be comparatively easy to determine clinically were selected as prognostic factors. The factors are (1) clinical stage, (2) morphology of the uterine cervix, (3) histological type of cancer and (4) radiosensitivity. Each prognostic factor and prognosis indicated in every case by chi-square test (X2 test) a risk rate lower than 0.1%, a significant difference. Furthermore, every prognostic factor was given points according to their grade, and the total points were expressed as a prognostic index. The prognostic index was classified into the mild zone (from 1 to 8 points), the moderate zone (from 9 to 10 points), and the severe zone (from 11 to 18 points), and the five year survival rate of each zone was observed to be 91.5%, 56.1% and 18.9% respectively. Thus, at a risk of less than 0.1%, a significant difference was observed. By setting up the prognostic index, it was possible to estimate the prognosis of every case of cervical carcinoma, which to date had been nearly impossible to estimate by each prognostic factor alone.

  17. Is excretory urography necessary in the staging work-up of uterine cervical carcinoma?

    International Nuclear Information System (INIS)

    Excretory urography has been routinely included in the staging work-up of uterine cervical carcinoma in the ear of popular use of computerized tomography (CT). The purpose of this retrospective study was to evaluate the necessity of excretory urography in the staging of uterine cervical carcinoma in addition to the routine CT. In 143 patients with histologically proven uterine cervical carcinoma, we compared excretory urography with CT, in respect to the ability of each study to demonstrated the pelvocalyces and the ureters, the level and the cause of the ureteral obstruction, and the invasion of urinary bladder. The results were as follows: Pelvocalyces and proximal ureters were demonstrated in 95% or more both on excretory urography and on CT, however, middle and distal ureters were demonstrated on CT better than on excretory urography. In 6 patients with ureteral obstruction by the extension of uterine cervical carcinoma, CT was more informative than excretory urography in respect to the level and the cause of the ureteral obstruction. CT was superior to excretory urography to confirm the presence or absence of the bladder invasion. From these results, we suggest that excretory urography can be omitted in the era of routine inclusion of CT in the staging work-up of uterine cervical carcinoma

  18. Role of protease activated receptor-2 in lymph node metastasis of uterine cervical cancers

    International Nuclear Information System (INIS)

    Protease activated receptor-2 (PAR-2) has been implicated in cellular proliferation, invasion and metastasis in various tumors. Lymph node metastasis is an important patient prognostic factor for uterine cervical cancers. This prompted us to study the role of PAR-2 in lymph node metastasis of uterine cervical cancers. Thirty patients underwent surgery for uterine cervical cancers. PAR-2 histoscores and mRNA levels were determined by immunohistochemistry and real-time reverse transcription-polymerase chain reaction, respectively. Patient prognosis was analyzed with a 48-month survival rate. PAR-2 histoscores and mRNA levels significantly (P < 0.05) increased in 12 of 30 metastatic lymph node lesions from the corresponding primary tumor. The 48-month survival rate of the 12 patients with increased PAR-2 levels in metastatic lymph nodes was 42%, while the rate of the other 18 patients with no change in PAR-2 levels was 82%, regardless of histopathological type. PAR-2 might work on lymph node metastasis of uterine cervical cancers, and is considered to be a novel prognostic indicator for uterine cervical cancers

  19. Electron microscopic study on radiosensitivity of uterine cervical cancer

    International Nuclear Information System (INIS)

    The effects of 1000 R of tele-cobalt upon the changes in the primary lesions of uterine cervical cancer with time were studied with an electron microscope. In addition, twenty cases which were proven to have cancer tissues (10 cases of IInd stage of cancer, 8 cases of IIIrd stage of cancer and 2 cases of IVth stage of cancer) were studied. Four cases were favourably sensitive, 7 cases moderately sensitive and 9 cases unfavourably sensitive to radiation. In favourably radio-sensitive cases, the changes in the cancer cells first appeared in the nucleus. There were other changes such as local clumping of chromatin and, specifically, vacuolization of the nucleus. The changes in the endoplasmic reticulum appeared somewhat late. In addition, the disturbance of mitochondria and the decrease or disappearance of ribosomes were specifically due to radiation injury. From the point of view of changes with time, Golgi's apparatus was enlarged and the membrane of the endoplasmic reticulum was degenerated at the 1st day. At the 3rd day, vacuolization of the nucleus appeared, the nuclear corpuscles were increased, the nucleoplasm became thin, and mitochondria was enlarged and degenerated. At the 5th day, the nuclear membrane disappeared, the nucleus was destroyed, large vacuolization of the endoplasmic reticulum was seen, free ribosomes were decreased, and changes around the endoplasmic reticulum were observed. At the 7th day, collagen around the endoplasmic reticulum appeared. In favourably radiosensitive cases, individual tumor cells showed the same degeneration, which fairly corresponded to that evaluated by the histological observation. The disturbance of the cells was caused by radiation, so-called ''burning'' of the cells. Radiation protection of the cells against burning was considered in terms of their radiosensitivity. (K.

  20. Super-selective uterine artery chemoembolization for the treatment of cervical cancer: its clinical value

    International Nuclear Information System (INIS)

    Objective: To evaluate super-selective uterine arterial chemoembolization therapy in the treatment of cervical cancer. Methods: Bilateral uterine arterial infusion with DDP, EADM or THP, MMC and 5-Fu was performed in 56 patients with pathologically-proved cervical cancer, which was followed by embolization of uterine arteries with iodine emulsion and Gelfoam particles. Radical hysterectomy was performed in 6 patients after interventional treatment. Results: Embolization of bilateral uterine arteries were successfully carried out in all cases. The angiography conducted during the procedure revealed markedly dilated uterine arteries, spiral tumor-feeding arteries and obvious tumor staining. The total effective rate was up to 94.6%. Six patients received radical hysterectomy 2 weeks after arterial chemoembolization, and the blood loss during the operation was much less than usual and the surgery procedure took shorter time. Ovarian necrosis was found in 1 case. The main adverse effects included leukocytopenia, nausea, vomiting and abdominal pain. Conclusion: Super-selective uterine arterial chemoembolization is a safe and effective supplementary therapy for cervical carcinoma with fewer complications. (authors)

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

  3. Evaluation of magnetic resonance imaging in the diagnosis of extension in uterine cervical cancer cases

    International Nuclear Information System (INIS)

    To prove the usefulness of magnetic resonance imaging (MRI) in determining the invasion of uterine cervical cancer with imaging planes, we evaluated 44 patients with histologically proved cervical cancer. MRI was performed with a Signa 1.5 T (General Electric), and a T2-weighted image was used. In coronal planes, the accuracy was 75.0% for parametrial invasion. It was impossible to diagnose in 77.8%, 92.1% and 63.2% the invasion of the uterine body, bladder, and rectum, respectively. In axial planes, the accuracy was 76.3%, 92.1% and 78.9% for the invasion of parametrium, bladder and rectum, respectively. It was impossible to diagnose in 72.2% the invasion of the uterine body. In sagittal planes, the accuracy was 80.6%, 97.4% and 89.7% for invasion of the uterine body, bladder and rectum, respectively. In all 39 cases it was impossible to diagnose parametrial invasion. In five cases, MRI failed to detect the tumor in any of the three planes, but in three cases it was able to detect the tumor in at least one of the three. We conclude as follows: MRI is a useful method in determining the invasion of cervical cancer. Coronal planes are recommended for the determination of parametrial invasion, axial planes for the parametrium, bladder and rectum, and sagittal planes for the uterine body, bladder and rectum. All three planes are needed to determine cervical cancer. (author)

    To avoid improper tumor volume contouring in radiation therapy (RT) and other invasive procedures, we report a case of uterine adenomyosis showing increased 18F-fl uorodeoxyglucose (FDG) uptake on positron emission tomography (PET)/computed tomography (CT) mimicking malignant tumor in a 44-year-old woman during concurrent chemoradiation therapy (CCRT) for uterine cervical cancer. The adenomyosis was not associated with her menstrual cycle or with normal endometrium uptake, and it resolved one month after completion of RT. This case indicates that uterine adenomyosis in a premenopausal woman may show false positive uptake of 18FDG-PET/CT associated with CCRT.

  5. Lumber and cervical osseous erosions secondary to herniated disks

    International Nuclear Information System (INIS)

    Only seven cases of lumber vertebral body or lateral recess enlargement have been reported previously in the English-language literature. The authors studied six cases of herniated nucleus pulposus (HNP) that was causing bone erosion. Five were in the lumbar spine, and one was in the cervical spine. All five lumbar HNPs were eroding the osseous contours of the lateral recess (the posterior vertebral body and pedicles). Two of the lumbar disks were sequestered posterolaterally and also were eroding the lamina aggressively. The cervical HNP had resulted in erosion of intervertebral foramen, posterior vertebral body, and pedicle. Myelography, CT, and MR imaging all demonstrated the epidural defect. However, only CT convincingly demonstrated the bone erosion

    Objective: To describe the utility, histopathological basis, and clinical correlates of the broccoli sign. Methods: The committee on human research approved this HIPAA compliant study and waived written informed consent. Based on the records of the senior author and our multidisciplinary Gynecologic Oncology Tumor Board, we retrospectively identified thirteen women (mean age of 48.8 years; range, 34-74) with a cervical mass seen at MR imaging (n = 13) or CT (n = 5) that demonstrated the previously reported broccoli sign (i.e., a soft tissue stalk connecting the cervical mass to the uterine cavity) on one or other modality. All available clinical, imaging, and histopathological records were reviewed, with particular emphasis on initially suspected diagnosis, final proven diagnosis, and outcome. Results: Cervical cancer was the initial clinically suspected diagnosis in 6 of 13 patients. Surgical resection demonstrated prolapsed uterine tumor in all patients, consisting of endometrioid adenocarcinoma (n = 7), carcinosarcoma (n = 2), adenosarcoma (n = 1), and leiomyoma (n = 3). Excluding the three patients with leiomyomas, currently, 7 patients with malignant tumors are disease free after a mean interval of 15 months (range, 3-45) and 3 patients have been lost to follow-up. Conclusion: A stalk connecting an apparent cervical mass seen at CT or MR imaging to the endometrial cavity ('broccoli sign') favors the diagnosis of a prolapsed uterine tumor; these prolapsed uterine tumors can often be malignant but appear to have a good prognosis.

    It is well known that intracavitary radiotherapy (ICR), either alone or in combination with external-beam radiotherapy (EBRT) is an essential component of the radiation treatment of uterine cervical cancer. Although low-dose-rate (LDR) brachytherapy has been successfully applied to the management of such patients, several radiation oncologists have experience of using high-dose-rate (HDR) brachytherapy with promising clinical results over the past 4 decades. However, there has been a considerable reluctance by radiation oncologists and gynecologists in North America to employ the HDR remote afterloading technique instead of the more firmly established LDR treatment modality. In contrast, the HDR-ICR system is rapidly gaining acceptance in Korea since the introduction of the Ralstron, remotely controlled afterloading system using HDR Co-60 sources, at the Yonsei Cancer Center in 1979. According to brachytherapy statistics reported by the Korean Society of Therapeutic Radiology and Oncology, in 1997, brachytherapy was performed upon 1,758 Korean patients with uterine cervical cancer, of whom approximately 83% received HDR brachytherapy. In this review, we present our experiences of HDR-ICR for the treatment of uterine cervical cancer. In addition, we discuss the controversial points, which are raised by those considering the use of HDR-ICR for uterine cervical cancer; these issues include physical and radiobiological considerations, and the prospect of future technical improvements.

  11. Value of intramuscular methotrexate and bilateral uterine artery embolization for treating cervical ectopic pregnancy

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of bilateral uterine artery chemotherapy embolization (UACE) for cervical ectopic pregnancy analyzed. Methods: Clinical records of 40 patients with cervical ectopic pregnancy treated using UACE were retrospectively analyzed. Results: 8 patients with severe active vaginal bleeding after curettage were treated urgently with UACE. The remaining 32 patients were treated with UACE combined with sequential ultrasound-guided curettage. Active vaginal bleeding was stopped after UACE. There was no recurrent hemorrhage with the sequential ultrasound-guided curettage procedure. The ?-HCG levels of all patients were normalized after 1 month. Conclusion: Bilateral uterine artery chemotherapy embolization is valuable as emergency treatment for patients with severe vaginal bleeding from cervical ectopic pregnancy. UACE combined with sequential ultrasound-guided curettage may be more effective. (authors)

  12. Superselective uterine artery chemoembolization for the treatment of cervical cancer: a clinical analysis of 33 cases

    International Nuclear Information System (INIS)

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

    Parturition involves increasing compliance (ripening) of the uterine cervix and activation of the myometrium. These processes take place in a different time frame. Softening and shortening of the cervix starts in midpregnancy, while myometrial activation occurs relatively close to delivery. Methods currently available to clinicians to assess cervical and myometrial changes are subjective and inaccurate, which often causes misjudgments with potentially adverse consequences. The inability to reliably diagnose true preterm labor leads to unnecessary treatments, missed opportunities to improve neonatal outcome, and inherently biased research of treatments. At term, the likelihood of cesarean delivery depends on labor management, which in turn depends on accurate assessments of cervical change and myometrial contractility. Studies from our group and others show that noninvasive measurements of light-induced fluorescence (LIF) of cervical collagen and uterine electromyography (EMG) objectively detect changes in the composition of the cervix and myometrial preparedness to labor and are more reliable than clinical observations alone. We present a conceptual model of parturition constructed on cervical LIF and uterine EMG studies. We also explore how these methodologies could be helpful with managing patients experiencing preterm contractions and with optimizing labor management protocols aimed to reduce cesarean section.

  14. Uterine cervical cancer. Usefulness of MR imaging after the initial radiation therapy

    International Nuclear Information System (INIS)

    To evaluate the usefulness of magnetic resonance imaging (MRI) in diagnosing residual or recurrent tumors of cervical cancer after radiation therapy, we investigated the time difference between MRI and gynecologic findings in the diagnosis of residual or recurrent tumor in 12 patients with invasive cervical cancer. We defined a positive finding for residual or recurrent tumor as an uterine cervical mass isointense to muscle on T1-weighted images and hyperintense on T2-weighted images, and when a positive biopsy specimen was obtained. Two patients were diagnosed as having a residual or recurrent tumor by MRI. Positivity was demonstrated four and seven months later, respectively. MRI was more useful in the earlier diagnosis of residual or recurrent tumor of cervical cancer after radiation therapy than uterine biopsy. There was one patient whose differentiation from residual tumor or radiation-induced necrosis or inflammation on MRI was difficult. MRI and gynecologic check-up at a regular interval after radiation therapy was needed to distinguish them. One patient was diagnosed as having a recurrent tumor by gynecologic finding three months earlier than by MRI. Follow-up MRI examinations at a regular interval in addition to gynecologic examination is necessary for the early detection of recurrent cervical cancer after radiation therapy. (author)

  15. Cerebellar metastases in patients with uterine cervical cancer. Two cases reports and review of the literature

    International Nuclear Information System (INIS)

    Brain metastases from cervical cancer are extremely rare. We report on two patients who developed cerebellar metastases following uterine cervical cancer. The interval between diagnosis of the primary cancer and diagnosis of brain metastasis was 8 months. The main complaint was symptoms of increased intracranial pressure and cerebellar syndrome. Surgical excision of the brain lesion followed by radiation therapy was performed in the first case. The second patient received palliative radiation therapy. The first patient died 8 months after diagnosis. The second patient is alive 2 months after diagnosis. (authors)

  16. A survey of patient comfort level with intracavitary brachytherapy for uterine cervical cancer

    We performed a survey of patient comfort level with intracavitary brachytherapy for uterine cervical cancer. Ninety-two patients from 5 institutions completed the survey. Even though current survey was done at the institutions where relatively active sedation were introduced, the comfort level of patients underwent tandem/ovoid applications were not sufficient. Some patients were not satisfied with mild intravenous (i.v.) sedation. In contrast, several patients required no premedication. Individualized sedation/analgesia methods should be considered.

    Spontaneous rupture of the renal pelvis and ureter is associated with obstruction of the urinary collecting system, but is rarely caused by tumors. We describe our experience with a patient who had uterine cervical cancer with mild hydroureter in whom spontaneous ureteral rupture occurred during concurrent chemoradiotherapy. The patient was a 66-year-old woman with stage IIIB uterine cervical cancer and mild hydroureter who received concurrent chemoradiotherapy. The patient felt uncontrolled right-side abdominal pain caused by ureteral rupture after she was given hydration and an intravenous bolus injection of furosemide during the first week of chemoradiotherapy. Contrast-enhanced computed tomography was more useful than ultrasonography for diagnosis of the ureteral rupture. The ureteral rupture in our patient was attributed to a rapid rise in the pressure of the urinary collecting system caused by hydration and the bolus injection of furosemide. Placement of a double-J stent before starting concurrent chemoradiotherapy may help to prevent ureteral rupture in patients who have uterine cervical cancer with mild hydroureter. PMID:26425712

  19. Therapeutic effect of intra-arterial chemotherapy with DDP and 5-FU via bilateral uterine arteries for advanced uterine cervical cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the therapeutic effect of intra-arterial chemotherapy with Ddp and 5-Fu via bilateral uterine arteries for advanced uterine cervical cancer. Methods: During the period of Jan. 2006-Jan. 2009, initial intra-arterial chemotherapy by using a combination of Ddp and 5-Fu via bilateral uterine arteries was performed in 72 patients (mean age 42.9 years) with advanced uterine cervical caner. Of 72 patients, stage I b2 cervical cancer was confirmed in 28, stage II a in 12 and stage II b in 32. Pathologically, cervical squamous cell carcinoma was seen in 56 and cervical adenocarcinoma in 16 patients. Ultrasonography and physical examination were conducted both before and after intra-arterial chemotherapy. The therapeutic results,complications,the surgical resection rate and the pathologic findings were observed and statistically analyzed. Results: Fifty-four patients received one treatment course and 18 patients received two treatment courses. The over all response rate was 77.8%. The response rates of patients with I b2, II a and II b cervical cancer were 92.9%, 83.3% and 62.5% respectively, the difference between three groups was statistically significant (P < 0.05). And the response rates of patients with squamous cell carcinoma and adenocarcinoma were 85.7% and 50.0% respectively, the difference between the two was statistically significant (P < 0.05). The most common side-effects included gastrointestinal symptoms and bone marrow suppression. Thirty-four patients received radical hysterectomy,among them, 22 (78.6%) had stage I b2, 8 (66.7%) had stage II a and 4 (12.5%) had stage II b cervical cancer (P < 0.05). Pathologic exam found no vaginal invasion and ovarian metastasis in all 34 patients. The occurrence of metastasis to lymph nodes and para uterine infiltration were 17.6% and 11.8% respectively. Conclusion: Intra-arterial chemotherapy with a combination of DDP and 5-Fu via bilateral uterine arteries can safely and effectively reduce the tumor volume of advanced cervical cancer, suppress the lymph node metastasis and parametrial infiltration, which is very helpful for creating favorable condition required by the surgery and for reducing the manipulative difficulties of radical hysterectomy. Intra-arterial chemotherapy has better effect on stage Ib2 cervical cancer than on stage II a and II b, and it is quite the same that intraarterial chemotherapy is more effective for cervical squamous cell carcinoma than for adenocarcinoma.

The annual incidence rate of lesions was determined, specifically by severity and age groups, and also the mortality rate for this cause. Results: the highest number of frequencies of cervical lesions diagnosed was detected in the year 2010 (72 women), the highest frequency corresponded to cervical intraepithelial neoplasias in stage I (low stage) (203 CIN I). The higher the lesions' degree of severity, the lower the frequencies, and thus the annual incidence rates. Mortality for cervical uterine cancer was acarce. Conclusions: increase in the number of premalignant lesions and the annual incidence rates. Increase in the number of premalignant lesions in young women (under 35 years of age) in comparison to those at age 35 or older. Increase in the number of in situ carcinoma within the time period. There was a decreasing tendency in the cases of invading cervical uterine carcinomata and the mortality for cervical uterine cancer.

  2. Pelvic insufficiency fracture after definitive radiotherapy for uterine cervical cancer. Retrospective analysis of risk factors

    International Nuclear Information System (INIS)

    The purpose of this study is to determine the incidence, clinical characteristics and risk factors of postradiation pelvic insufficiency fracture (PIF) in women with uterine cervical cancer. We reviewed the medical records of 126 patients who received definitive radiotherapy (RT) for uterine cervical cancer between 2003 and 2009 at our institution. Among them, 99 patients who underwent at least one computed tomography (CT) or magnetic resonance imaging of the pelvis during their follow-up at more than 6 months were included in this analysis. The relationship between the incidence of PIF and several patient- and treatment-related factors was analyzed. The median follow-up period was 21 months. Of the 126 patients, 33 (with a total of 50 lesions) were diagnosed with PIF. The 2-year cumulative incidence was 32%. Univariate analysis showed that age ?70 years (P= 0.0010), postmenopausal state (P = 0.0013), and lower CT density of bone and bone marrow (P = 0.020) significantly related to PIF. In a multivariate analysis, of the 59 patients whose CT densities were evaluable, lower CT density was the only significant factor associated with PIF (P = 0.0026). In conclusion, postradiation PIFs were detected in a considerable number of patients after definitive RT for cervical cancer. Predisposing factors were older age, postmenopausal state, and decreased density of bone and bone marrow on CT. (author)

    International Nuclear Information System (INIS)

    Objective: To observe the cervical cytological change after radiation therapy of cancer of uterine cervix and the clinical significance of Liquid-based cytology test (LCT). Methods: From 196 uterine cervical carcinoma patients, a total of 489 specimens of LCT were collected. All tests were performed one month after the conclusion of radiation treatment. Results: Detection rate of abnormal squamous epithelial cells was 40.3% (197/489), of which the findings of atypical squamous cells of undetermined significance (ASCUS), low grade squamous intraepithelial lesion (LSIL), high grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma(SCC) were observed in 20.1%, 5.3 %, 10.8% and 3.1% respectively. In benign reactive cervical cell detection, this article mainly describes the detection rate of inflammatory reactive cells which was 42.5%, of which the mild 6.34% inflammation took place, 19.4% moderate and 6.8% severe inflammation. All kinds of abnormal cell detection rates showed differences among each of the groups from 1 to 18 months of follow-up observation. Conclusions: Liquid-based cytology test may also be one of the predicting observation indexes if there is recrudescence locally in the future. (authors)

  4. Lumboaortic irradiation in uterine cervical cancer: Analysis of the literature

    International Nuclear Information System (INIS)

    Background: Uterine cancer is a prevalent disease in Chile and it is one of the most frequent cancer locations treated in the National Chilean Cancer Institute. It is also common to receive young patients that have advanced tumors in stages IIB and IIIB with high risks of compromises of lymphatic nodes of pelvis and aortic-lumbar zones. The treatment for these kinds of cancers is radio-chemotherapy. Aims: Determinate if the radiotherapy of aortic-lumbar lymph nodes lowers the chance of relapsing or increase the survival rate in patients with evident compromise of aortic-lumbar lymph nodes and in those with high risk of compromise in that level. Method: Exhaustive analysis of the literature about the indication of radiotherapy of aortic-lumbar lymph nodes in cervix cancer which is classified in those where the radiotherapy treatment is done in patients with evident compromise of aortic-lumbar lymph-nodes, and those where de radiotherapy is done in patients with high risk of compromise in that level. Results: In patients with small cervix tumors and positive lymphoid nodes the LA lymphatic nodes treatment would be beneficial. However, patients that suffer massive pelvic disease (IIIB) or that have evidence of the disease, the benefit would not be so important. Conclusion: Patients with controllable pelvic disease and with high risk of having aortic-lumbar lymph nodes compromise are the most benefit of radiotherapy in aortic-lumbar lymph nodes (stages IA-B, IIA-B with positive lymph nodes)

  5. Problems on the treatment of the uterine cervical cancer

    International Nuclear Information System (INIS)

    The 5 year survival rate of cervical cancer in Japan is 86% in Stage I, 67% in stage II, 37% in Stage III, and 12% in Stage IV separately. In the early cancer as Stage 0 and Stage Ia even 100% and 93% survival rates can be achieved, so in this group, reduction operation for function reservation is recommended. On the other hand in the advanced cancer, the result of the treatment is unsatisfied yet, and better therapy must be considered. This report discuss the effect and the limit of operation therapy and postoperative radiotherapy, as well as the prognosis and side-effect of the radiotherpy in the viewpoint of the doses. (author)

  6. Staging uterine cervical carcinoma with low-field MR imaging

    International Nuclear Information System (INIS)

    To assess the validity of low-field MR in staging cervical cancer compared to clinical staging. Material and Methods: A total of 95 women entered the study over a 3-year period. MR examinations with a 0.1 T resistive magnet using a body coil and clinical staging according to the FIGO recommendations were performed within 2 weeks from clinical diagnosis. T1- and T2-weighted sequences were obtained in transversal and sagittal acquisitions, and an additional T1 before and after contrast (randomisation to 0.1 or 0.3 mmol/kg b.w. gadodiamide). Treatment decisions on surgery or radiation therapy were made solely on the clinical staging. Results: Sixty-one patients were found to be eligible for surgery. In 5 women, the pathological results revealed a more advanced stage of the disease than assessed by clinical staging. MR correctly staged 4 of the 5 but otherwise tended to overstate the disease. Contrast enhancement significantly reduced this trend (p<0.05) regardless of the contrast medium dose used. Divided into two groups, an operable (less than stage 2b) and an inoperable group (more than stage 2a), the clinical staging correctly classified 57 patients (accuracy 92%) compared to 52 patients with MR using contrast enhancement (accuracy 84%). The specificity was no higher than 31%, whereas the reproducibility of the MR assessment was fairly good with kappa values around 0.65 for both intra- and interobserver variations. Conclusion: In the present set-up, clinical assessment was superior to low-field MR in staging cervical cancer. When using contrast enhancement, the staging accuracies of low-field MR were comparable to the ones reported for techniques with higher tesla values, whereas the specificity and reproducibility errors were lower. The method, therefore, needs to be optimised

  7. Clinical outcomes of adjuvant radiation therapy and prognostic factors in early stage uterine cervical cancer

    International Nuclear Information System (INIS)

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic significance in early uterine cervical cancer patients. More effective systemic treatments might be needed to reduce distant metastasis in these patients

  8. Usage of CT and tumor markers in the management of a patient with cervical cancer after colpocleisis for uterine prolapse

    International Nuclear Information System (INIS)

    A 79-year-old woman developed stage IIIb cervical carcinoma 13 years after colpocleisis for uterine prolapse. The patient was treated with external irradiation of 60 Gy and chemotherapy with 5-FU (100 mg/day) and Ok-432. The response of tumor could be monitored by serial changes in tumor markers, such as SCC, IAP, TPA, CEA, LDH, and ALP, and CT findings. Considering that colpocleisis makes it impossible to visualize the uterine cervix, the adequate selection of surgical procedure for uterine prolapse is required. (Namekawa, K.)

    Full Text Available Initially used for diagnostic, laparoscopy has become a method of treatment in the field of gynecological surgery, but also in many other fields. The results of laparoscopic surgery are now comparable with those obtained by laparotomy in benign and malignant pathologies. Laparoscopy provides improved results in the short term and at least equivalent results in terms of long-term recurrence when compared with open surgery. Robotic-assisted laparoscopy was performed to prevent the disadvantages of conventional laparoscopy. It emerged as a revolutionary technology and has spread in less than a decade in many surgical fields, including urology, cardiothoracic surgery, pediatric surgery and general surgery. Minimally invasive techniques provide a lower rate of complications during surgery as compared to open surgery, which is appropriate tissue due to handling and better anatomical views. Laparoscopic treatment of cervical cancer provides benefits on increasing comfort with decreased convalescence time, but these cases should be reserved for surgeons with extensive experience in laparoscopic procedures. One of the most important advantages of minimally invasive surgical techniques is the short duration of hospitalization.

  10. Significance of total hysterectomy for uterine cervical cancer persistent in the uterine cervix after radiotherapy

    International Nuclear Information System (INIS)

    Radiation therapy is an important means for treating advanced cases of cervical cancer. There are cases, however, in which cancer cells persist even after treatment has been completed. We in the Department of Gynecology at the Cancer Institute Hospital actively performed total hysterectomies in such patients with no distant metastases and no extension of the parametrial induration to the pelvic wall, and obtained favorable results. In the present study, the clinical stage, histological type, degree of removal of involved tissue, and relationship between the prognosis and the maximum diameter of the tumor in the extirpated uterus were examined in 28 patients with advanced cervical cancer treated during the thirty-year period from 1957 to 1986. The following results were obtained: 1. The clinical stage and histological type of the cancer prior to radiation therapy did not significantly affect the prognosis after total hysterectomy. 2. The 3-year survival rate for the patients in whom all involved tissue could be removed was 81.0 percent. In contrast, all those in whom complete removal was impossible survived less than 3 years, despite additional therapy. 3. Prognosis was better in the patients who had tumors with a maximum diameter of less than 2 cm than in those who had tumors with a maximum diameter of 2 cm or more (p < 0.05). 4. Patients in whom all involved tissue could be removed and in whom the maximum diameter of the tumor was less than 2 cm had a good prognoses, with 88.9 percent surviving at least 3 years after surgery.

  11. Clinical Significance of CENP-H Expression in Uterine Cervical Cancer

    International Nuclear Information System (INIS)

    This work aims to investigate the expression pattern and clinicopathologic significance of centromere protein H (CENP-H) in uterine cervical cancer (UCC). The level of CENP-H expression in the paraffin sections of 62 UCC cases was determined by the SP immunohistochemical method, with complete clinicopathologic data in all cases. Statistical analysis was conducted to evaluate the prognostic and diagnostic significance of CENP-H using SPSS13.0 software package. Immunohistochemical assay showed strong CENP-H expression in 61.29% (38/62) of the paraffin-embedded cervical cancer tissues. Statistical analysis revealed a strong correlation between the CENP-H expression and the clinical classification (P=0.038) of the cervical carcinoma. The expression increased with rise of the stages. The analysis of Cox proportional hazards regression model suggested that CENP-H expression (P=0.002) and tumor stage (P=0.001) were independent prognostic markers for the survival of UCC patients. The survival analysis showed that the survival rate was significantly lower in patients with high expression of CENP-H than in those with low expression of CENP-H (P=0.001). CENP-H is likely to be a valuable marker for carcinogenesis and progression of UCC. It might be used as the important diagnostic and prognostic marker for cervical carcinoma patients, especially for those at early stage

  13. Biological properties and radiation responses of the hamster uterine cervical squamous cell carcinoma

    International Nuclear Information System (INIS)

    Results of initial studies of the growth characteristics, immunogenicity, histopathology, and radiation response of a uterine cervical squamous cell carcinoma of the Syrian hamster are presented. The cervical carcinoma is a relatively loosely knit, undifferentiated, highly cellular tumor without a recognizable architectural pattern but with a gradation in cellular density decreasing from the perimeter to the center of the tumor. The vascular network corresponds with the histologic features such that radially arranged capillaries join a dilated, tortuous network at the perimeter and with a sparse network in the center of the tumor. Tests of the immunogenicity of the cervical carcinoma by either suppressing the immune mechanism(s) or sensitizing the animal to the tumor indicate that this tumor provides little or no stimulus to the host immunologic system. After radiation exposures ranging from 1000 to 7000 R, tumor volume in persisting tumors shows a pattern of retardation and/or regression followed by regrowth which correlates with exposure. Increasing tumor control occurs with exposures of 3000 R and higher producing a TCD50120 days of 5800 +- 1100 R. The cause of death in animals containing persisting tumors could be attributed to extensive pulmonary metastases and/or intercurrent infection relative to ulceration and necrosis of the tumor. The major advantages of the use of the Syrian hamster and the cervical carcinoma as a model system and as an interface for the comparison of data from other established tumor models with that from transplantable xenogenic tumor systems is also presented

  14. Effect of 5'-DFUR used concurrently in radiotherapy and immunotherapy uterine cervical cancer. Pilot study

    International Nuclear Information System (INIS)

    We conducted a preliminary controlled study in order to evaluate 5'-DFUR dose dependency in efficacy and safety in combination therapy of radiotherapy, 5'-DFUR and SPG for patients with uterine cervical cancer, which was regarded as suitable for cases of radiotherapy. The patients were randomly allocated into group A (5'-DFUR 600 mg/body/day) and group B (5'-DFUR 800 mg/body/day), who underwent radiotherapy with simultaneous administration of 5'-DFUR and SPG (20 mg twice/week or 40 mg/week). Those enrolled were 33 patients in stage II, III or IVa with histologically diagnosed primary squamous cell carcinoma of uterine cervix. CR was shown in 19, PR in 7, NC in 1, and PD in 2 out of 29 efficacy-evaluable cases, so the overall response rate was 89.7% (26/29, 95%CI 72.7%-97.8%). Regarding safety, some side effects were observed in 26 out of 33 safety-evaluable cases (81.3%, 95%CI 63.6%-92.8%), but no serious cases. No significant difference in efficacy and safety was observed between the two treatment groups. These results suggested that the combination therapy of radiotherapy, 5'-DFUR and SPG might be one of the therapies whose effectiveness must be confirmed for advanced squamous cell carcinoma of uterine cervix. To confirm dose dependency of 5'-DFUR, it seems further consideration with more patients is needed. (author)

  15. Cytopathological and immunohistochemical study for estimating radiotherapeutic effects in uterine cervical cancer

    International Nuclear Information System (INIS)

    In order to estimate the effects of radiation on cancer tissue, cytopathological findings, BrdU labelling index (L.I), tumor markers and C-myc oncogene products were examined in 30 patients of uterine cervical cancer, before radiation, at around 10 Gy, 30 Gy, 50 Gy and at the end of the therapy. In order to assess the radiotherapeutic effects, the cytological, histological, immunohistological findings were evaluated by Papanicolaou's classification, Oboshi and Shimasato's grading system and BrdU L.I. In the cytology, the radiation effect, such as the enlargement and vacuolation of the nuclei and cytoplasm, was observed at around 10 Gy of radiation, and significantly increased at around 30 Gy showing lysis of the cells and pyknosis of the nuclei. The histological observation recorded remarkable change in the cancer tissue at around 30 Gy of radiation. The BrdU L.I. showed a meaningful decrease around 30 Gy in the radiosensitive cases compared with the radioresistant cases. Moreover, immunohistochemical investigation indicated the location of SCC and SLX in the cytoplasm of the cancer cells and of C-myo oncogene product at around 10 Gy. Ras oncogene was not found in the adenocarcinoma cases investigated. From these findings it is concluded that BrdU L.I., revealed by immunohistological study, is the most suitable indicator to estimate the response of radiation in cancer cells of the uterine cervix and that C-myc oncogene product has the potentiality to be used as a prognostic factor in uterine cervical cancer treated by radiation therapy.

    2010-01-01

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

  17. Protein profiling underscores immunological functions of uterine cervical mucus plug in human pregnancy

    2011-01-01

    The cervical mucus plug (CMP) differs from the cervical secretions of non-pregnant women, and is the ultimate sealant of the uterine cavity during pregnancy. Although several studies have analyzed biochemical properties of large glycoproteins in the CMP, comprehensive information about its protein composition is yet unavailable. We hypothesized that protein profiling of the CMP could provide key clues to its physiological functions in pregnancy. For this purpose, five CMPs obtained from women in labor at term were analyzed by LC-MS/MS. Out of 291 total proteins identified, 137 were detected in two or more samples, which included S100A8, S100A9, and complement proteins (C3, C4a, C4b, C6, and C8g). Several proteins, which have not been described in the cervical mucus of non-pregnant women or in cervicovaginal fluids, such as CD81 antigen and pregnancy zone protein, were also identified. Gene ontology analysis of identified proteins showed significant enrichment of 28 biological processes such as 'activation of plasma proteins involved in acute inflammatory response' and 'positive regulation of cholesterol esterification'. We report the proteome of CMPs from pregnant women at term for the first time, and the overall findings strongly suggest an important role for the CMP in the maintenance of pregnancy and parturition.

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic significance in early uterine cervical cancer patients. More effective systemic treatments might be needed to reduce distant metastasis in these patients.

    CD24, a small heavily glycosylated mucin-like glycosyl-phosphatidylinositol-anchored cell surface protein, plays an important role in the carcinogenesis of various human malignancies. However, its function in cervical cancer remains unclear. The aim of the present study was to evaluate the expression of CD24 clinicopathologically and to analyze its functional behavior biologically in cervical cancer. A total of 117 uterine cervical cancer tumors were immunohistochemically analyzed using a CD24 monoclonal antibody on paraffin blocks. We also examined whether CD24 enhanced the invasive activity or the Akt, ERK, NF-?B and MMP activity in a uterine cervical cancer cell line (CaSki) by a western blot analysis. The patients with enhanced CD24 expression had a higher rate of advanced clinical stage (50 vs. 16.5%, p<0.01), lymph node metastasis (34.6 vs. 14.3%) and lymphovascular involvement (65.4 vs. 20.4%, p=0.01), and a poor overall and disease-free survival (5-year survival rate: 62 vs. 86%, p=0.03). CD24 overexpression in CaSki cells resulted in activation of Cell Signaling proteins, including Akt, ERK, NF-?B and MMP-9. An invasion assay showed that CD24 overexpression in CaSki cells led to increased invasion ability. The CD24 overexpression also increased mRNA expression of Slug but not Snail. Moreover, the CD24 overexpression also decreased expression of E-cadherin and increased N-cadherin protein levels. Increased expression of CD24 may be associated with tumor progression and prognosis in patients with uterine cervical cancer. CD24 expression may therefore be used not only as a prognostic marker in uterine cervical cancer, but also as a target for the development of new therapeutic approaches. PMID:26351781

  20. Dynamic contrast-enhanced MRI in the diagnosis of uterine cervical cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the imaging characteristics of dynamic contrast-enhanced MR imaging (DCE-MRI) in uterine cervical cancer(UCC), and to evaluate the efficacy of DCE-MRI in the diagnosis of UCC. Methods: A total of 39 cases of scratch-pathologically confirmed UCC patients with MRI data were analyzed (one case of carcinoma in sim being negative on MRI was excluded in this study). Time- intensity curves of ROI in pathological regions and adjacent normal regions were obtained and the enhanced rates at different times (16,32,48,64 and 300 s) were calculated. The ARSI% and MRSI% of various groups were compared with t test. Results: All the 39 lesions enhanced at 16 s in DCE, and there was maximum signal contrast between lesions and the surrounding normal tissue in the early arterial phase. ARSI% of tumor (1.97 ± 0.55)% was higher than normal tissue (1.22 ± 0.56 )%, and there was statistically significant difference between them (t=151.000, P3 cm group[(1.70 ± 0.25)% and (2.26 ± 0.18)%] were higher than ?3 cm group [(0.57 ± 0.16)% and (0.73 ± 0.04)%]. ARSI% and MRSI% were higher in the peri-uterine tissue infiltration group [(1.69 ± 0.21)% and (2.26 ± 0.11)%] than that of confined group [(0.63 ± 0.23)% and (0.83 ± 0.03)%] with statistically significant difference (P<0.05). The TIC of the 39 cases with UCC included type I in 25 cases(25/39), type II in 14 cases (14/39), and there was no type III cases. The TICs of the surrounding normal tissue were of type III (26/39) and type II (11/39), and only 2 cases type I. Conclusions: The DCE-MRI can reflect the blood supply of the UCCs quantitatively. The early arterial phase in DCE-MRI can improve the detection rate of small lesions. The ARSI% and MRSI% may be helpful in some degree in prognostic assessment and staging of the uterine cervical cancer. (authors)

  1. Changes in Bone Mineral Density in Uterine Cervical Cancer Patients After Radiation Therapy

    International Nuclear Information System (INIS)

    Purpose: To prospectively investigate the changes in bone mineral density (BMD) after pelvic radiation therapy in patients with uterine cervical cancer. Methods and Materials: Of 52 cervical cancer patients who received pelvic RT in our university hospital between 2009 and 2011, 46 patients without recurrence and who were followed up for more than 12 months were included in the study. The BMD of the irradiated region and nonirradiated regions, serum estradiol, tartrate-resistant acid phosphatase-5b, and N-terminal cross-linking telopeptide of collagen 1 were measured before, at 3 months after, and at 12 months after RT. The patient cohort was divided into 2 groups according to estradiol level before RT, and the groups were defined as postmenopausal (2 before RT and 0.746 and 0.841 g/cm2 12 months after RT, respectively. Significant decreases were observed in both groups (P2 before RT and were significantly decreased to 0.706 and 0.921 g/cm2 12 months after RT (P<.01 and P<.05, respectively). Estradiol significantly decreased 3 months after RT, whereas tartrate-resistant acid phosphatase-5b and N-terminal cross-linking telopeptide of collagen 1 continued to increase over time in the premenopausal group. Conclusions: A decrease in BMD in the irradiated region after RT was observed within 1 year, regardless of menopausal status. Furthermore, in premenopausal patients, pelvic RT caused a decrease in systemic BMD

In this paper we provide a detailed review of the epidemiology of cervical cancer, with emphasis on related risk factors associated with carcinogenesis and delayed diagnosis.

  3. Clinical significance of magnetic resonance imaging (MRI) in evaluation of radiotherapeutic effect on uterine cervical cancer

    International Nuclear Information System (INIS)

    Serial magnetic resonance imaging (MRI) studies were performed in 27 patients undergoing primary radiation therapy for invasive cervical carcinoma, to assess the efficacy of this therapy. MRI findings included a high intensity area (HIA) in the uterine cervix and five parameters indicative of extrauterine spreading of the carcinoma: vaginal invasion, parametrial invasion, vesical invasion, rectal invasion and lymph node enlargement. In 26 of the 27 (96%) cases, the HIA was found prior to treatment, and remained in 17 (63%) cases at the end of the treatment. But in 10 of the patients with a residual HIA, this region resolved 3 to 8 months after treatment, and these patients had no evidence of residual tumor in the cervix on pathologic examination. The accuracy was lower in MRI examinations performed less than 6 months after the treatment (49%) than in examinations performed more than 7 months after the treatment (93%), suggesting that the HIA in the early post-treatment phase may be related to inflammatory changes. Findings indicative of extrauterine spreading decreased following treatment, but patients with recurrence had higher scores than those with no evidence of recurrence completion of the primary therapy. Furthermore, in 2 patients with local recurrence more than 1 year after treatment, the abnormal MRI findings reappeared and increased after the initial resolution of these findings with treatment. The present results indicate that MRI is clinically effective in evaluating the effects of radiotherapy in patients with cervical cancer. (author)

    Granulocyte-colony stimulating factor (G-CSF) producing malignant tumor has been reported to occur in various organs, and has been associated with poor clinical outcome. The aim of this study is to investigate the significance of tumor G-CSF expression in the chemosensitivity of uterine cervical cancer. The clinical data of recurrent or advanced cervical cancer patients who were treated with platinum-based chemotherapy were analyzed. Clinical samples, cervical cancer cell lines, and a mouse model of cervical cancer were employed to examine the mechanisms responsible for the development of chemoresistance in G-CSF-producing cervical cancer, focusing on myeloid-derived suppressor cells (MDSC). As a result, the tumor G-CSF expression was significantly associated with increased MDSC frequencies and compromised survival. In vitro and in vivo experiments demonstrated that the increased MDSC induced by tumor-derived G-CSF is involved in the development of chemoresistance. The depletion of MDSC via splenectomy or the administration of anti-Gr-1 antibody sensitized G-CSF-producing cervical cancer to cisplatin. In conclusion, tumor G-CSF expression is an indicator of an extremely poor prognosis in cervical cancer patients that are treated with chemotherapy. Combining MDSC-targeting treatments with current standard chemotherapies might have therapeutic efficacy as a treatment for G-CSF-producing cervical cancer. PMID:26666576

  5. Clinicopathological analysis of 91 cases of uterine cervical cancer (including 38 cases of CIN III)

    International Nuclear Information System (INIS)

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

    Aim of the study. The development of modern radiotherapy techniques requires focusing attention on potential side effects and on the quality of life. The aim of the study was to assess radiation toxicity and quality of life in patients with cervical and endometrial cancer treated with conventional and conformal pelvic radiotherapy and to assess the impact of radiation toxicity on the latter. Material and methods. 50 patients treated with conventional and 50 patients treated with conformal pelvic radiotherapy in Clinical Department of Gynecological Radiotherapy in Lower Silesian Oncology Center between November 2004 and October 2005 entered a prospective study. We estimated the side- effects of radiotherapy according to EORTCI RTOG scales and quality of life according to the EORTC QLQ-C30 questionnaire. Results. There were no differences in physical, cognitive, emotional and role functions between the two study groups. Social functions were assessed as worse in the conformal radiotherapy group. Pain was more frequent in the conformal arm and nausea in the conventional arm. Global health and quality of life were better in the conformal arm. The performance status according to WHO affected global health and quality of life and physical functions. Late side-effects from the gastrointestinal system impaired physical, cognitive, emotional and social functions and global health and quality of life. Genitourinary late side- effects impaired physical functions and global quality of life. Conclusions. We observed no important differences in the quality of life in patients with cervical and uterine cancer receiving conventional and conformal external beam pelvic radiotherapy. Performance status according to WHO and gastrointestinal and genitourinary late side-effects affect quality of life. (authors)

    Purpose: To prospectively investigate the changes in bone mineral density (BMD) after pelvic radiation therapy in patients with uterine cervical cancer. Methods and Materials: Of 52 cervical cancer patients who received pelvic RT in our university hospital between 2009 and 2011, 46 patients without recurrence and who were followed up for more than 12 months were included in the study. The BMD of the irradiated region and nonirradiated regions, serum estradiol, tartrate-resistant acid phosphatase-5b, and N-terminal cross-linking telopeptide of collagen 1 were measured before, at 3 months after, and at 12 months after RT. The patient cohort was divided into 2 groups according to estradiol level before RT, and the groups were defined as postmenopausal (<40 pg/mL) and premenopausal (?40 pg/mL). Results: The mean BMDs within the irradiation field (lumbar vertebra 5) in the postmenopausal and the premenopausal groups were 0.825 and 0.910 g/cm{sup 2} before RT and 0.746 and 0.841 g/cm{sup 2} 12 months after RT, respectively. Significant decreases were observed in both groups (P<.05 and P<.01, respectively). In addition, in the premenopausal group the mean BMDs of the nonirradiated regions at thoracic vertebrae 9-12 and lumbar vertebrae 2-4 were 0.753 and 0.958 g/cm{sup 2} before RT and were significantly decreased to 0.706 and 0.921 g/cm{sup 2} 12 months after RT (P<.01 and P<.05, respectively). Estradiol significantly decreased 3 months after RT, whereas tartrate-resistant acid phosphatase-5b and N-terminal cross-linking telopeptide of collagen 1 continued to increase over time in the premenopausal group. Conclusions: A decrease in BMD in the irradiated region after RT was observed within 1 year, regardless of menopausal status. Furthermore, in premenopausal patients, pelvic RT caused a decrease in systemic BMD.

  10. Unstable chromosome aberrations on peripheral blood lymphocytes from patients with cervical uterine cancer following radiotherapy

    International Nuclear Information System (INIS)

    Absorbed dose determination is an important step for risk assessment related to an exposure to ionizing radiation. However, physical dosimetry cannot be always performed, principally in the case of retrospective estimates. In this context, the use of bioindicators (biological effects) has been proposed, which defines the so-called biological dosimetry. In particular, scoring of unstable chromosomes aberrations (dicentrics, centric rings and fragments) of peripheral blood lymphocytes, while is the most reliable biological method for estimating individual exposure to ionizing radiation. In this work, blood samples from 5 patients, with cervical uterine cancer, were evaluated after partial-body radiotherapy with a source of 69 Co. For this, conventional cytogenetic method was employed, based on Giemsa coloration and fluorescence in situ hybridization, in order to correlate the frequency of unstable chromosome aberrations of blood lymphocytes with absorbed dose, as a result of the radiotherapy. A good agreement was observed between the frequency of chromosome aberrations scored and the values of dose previously calculated by physical dosimetry during patient's radiotherapy. The results presented in this work point out the importance of concerning analyses of unstable chromosome aberrations as biological dosimeter in the investigation of partial-body exposure to ionizing radiation.

    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

    Full Text Available Cervical erosion, a pathological change associated with chronic cervicitis, is a common condition that is difficult to cure. Many patients particularly those with mild or medium infection and those preparing for pregnancy require a simple but effective medication. In this study, extracts of an empirical herbal prescription composed of six Chinese traditional drugs viz Cortex Phellodendri, Rhizoma Coptidis, Olibanum, Myrrha, borneol and catechu were formulated to facilitate intravaginal administration and improve efficacy. An extract of the first four components was formulated with borneol as a thermosensitive gel (TG while an extract of catechu used to prepare a regular gel (CG because of a chemical incompatibility. The optimized TG was prepared using poloxamer 407 and poloxamer 188. The CG was prepared using glycerin, carbopol and triethanolamine. The gels were characterized in vitro in terms of release of berberine (TG and total catechins (CG and in vivo in a rat model of cervical erosion. Treatment by once daily application of the TG for 7 days followed by once daily application of the CG for 3 days produced a restoration of normal tissues. Gel formulation of the empirical Chinese traditional remedy appears to provide a promising treatment for cervical erosion.

    Objective: To evaluate the efficacy of post-treatment positron emission tomography (PET)/computed tomography (CT) for identification of tumor recurrence, and to determine whether [{sup 18}F]fluorodeoxyglucose (FDG) uptake measured as the maximum standardized uptake value (SUV{sub max}) has predictive role regarding survival in patients with uterine cervical cancer. Methods: Medical records from 276 women with uterine cervical cancer who had post-treatment [{sup 18}F]FDG PET/CT performed were retrospectively reviewed. Results of PET/CT scans were compared with histological or clinical examination. Results: Ninety-five (34.4%) of the 276 patients had documented recurrence by either surgical biopsy or clinical and imaging follow-up. Median duration from treatment to PET/CT scan was 24 months (range, 6-307). The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of post-treatment PET/CT were 94.7%, 87.8%, 80.4%, 97%, and 90.2%, respectively. The PET/CT scan modified both the diagnostic or treatment plan in 67 patients (24.3%). Patients were divided into two groups according to cut-off SUV{sub max} established on the basis of ROC analysis (<5.25 vs. {>=}5.25), and there was a significant difference in OS between groups (p = 0.001). In addition, the 5-year progression-free survival (PFS) and OS rates of patients with a negative PET/CT scan for recurrence were significantly better than those with a positive PET/CT (98.62% vs. 17.83%, p < 0.0001 for PFS, 99.31% vs. 85.38%, p = 0.0015 for OS). Conclusion: Post-treatment PET/CT scan is a sensitive and accurate surveillance modality, and provides prognostic information in uterine cervical cancer. Furthermore, it may allow individualization of patient care.

  14. Role of CD24 Protein in Predicting Metastatic Potential of Uterine Cervical Squamous Cell Carcinoma in Patients Treated With Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The protein CD24 is a cell surface protein that appears to function as an adhesion molecule; its expression has been shown to correlate with prognosis in a variety of tumors. The aim of this study was to evaluate the immunoreactivity of uterine cervical squamous cell carcinoma to CD24 and determine whether CD24 is associated with clinical and pathologic parameters, including prognosis. Methods and Materials: The expression of CD24 protein was immunohistochemically studied in 73 cases of uterine cervical squamous cell carcinoma. All patients were treated with definitive radiotherapy alone or with concurrent chemoradiotherapy. Two pathologists independently analyzed the immunostaining; they did not have knowledge of the patient outcomes and evaluated any changes according to the percentage of tumor cells stained as follows: negative, 5% reactive. Results: Positive staining was found in 43 cases (58.9%). The immunoreactivity did not correlate with age, International Federation of Gynecology and Obstetrics stage, lymph node metastasis, or tumor size. For patients who were CD24 negative, the total failure and distant metastasis rates were decreased about 20% compared with the rates for patients who were CD24 positive. On univariate analysis, the 5-year distant metastasis-free survival rate of CD24-negative patients was significantly greater than that of the CD24-positive patients (84.7% vs. 66.7%, respectively, p = 0.0497). The International Federation of Gynecology and Obstetrics stage and CD24 expression were significantly associated with distant metastasis-free survival on multivariate analysis. Conclusions: CD24 expression was a significant independent prognostic factor for distant metastasis-free survival in patients with uterine cervical squamous cell carcinoma. In the future, prospective determination of CD24 expression might aid clinical practice in the selection of the appropriate therapy for individual patients

    International Nuclear Information System (INIS)

    The efficacy of combined therapy of intra-arterial reservoir and radiotherapy was studied on 12 patients with advanced cervical uterine cancer. The patients were classified into two groups according to the agents used: Group A, intra-arterial administration of CDDP (10 mg/body/day) and 5-FU (250 mg/body/day) for 10 days; Group B, oral administration of Vp-16 (25 mg/body/day) for 7 days, followed by intra-arterial infusion of CDDP (100 mg/m2) for the first day and ADM (50 mg/m2) for the third day and intravenous infusion of CPM (200 mg/body/day) for 3 days. The size of tumor was reduced by several courses of chemotherapy preoperatively, then radiotherapy was performed. Whole-pelvis irradiation (40 Gy) was performed on 11 patients postoperatively, and internal irradiation (20 Gy) was performed preoperatively on 3 to control genital hemorrhage and postoperatively in 6. The reduced tumor size was evaluated by CT and MR. The efficacy rate was 75% (CR, 1; PR, 5; NC, 2)in the Group A and 50% (PR, 2; NC, 2) in the Group B, showing that intra-arterial infusion alone is enough to reduce the tumor size. Occlusion of the anterior raminus of left internal iliac artery was observed in one in the Group A. Transient leukopenia was observed in 2 in the Group A, which did not required any special treatment, and all patients in the Group B showed bone marrow suppression. The selection of irradiation field is still controversial, which needs to be further studied. (S.Y.)

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    To determine if preoperative [{sup 18}F]FDG-PET/CT imaging has prognostic significance in patients with uterine cervical cancer. Patients with FIGO stage IB to IIA cervical cancer were imaged with integrated FDG PET/CT before radical surgery. The relationship between the maximum standardized uptake value (SUV{sub max}) of FDG in the primary tumour during PET/CT and recurrence was examined. Included in the study were 75 patients. Medical records including clinical data, treatment modalities, and treatment results were retrospectively reviewed. The median duration of follow-up was 13 months (range 3 to 58 months) after treatment. Median preoperative SUV{sub max} values in the primary tumours were significantly higher in patients with higher FIGO stages (p = 0.0149), pelvic lymph node metastasis (p = 0.0068), parametrial involvement (p = 0.0002), large (>4 cm) tumour size (p = 0.0022), presence of lymphovascular space invasion (p = 0.0055), and deep cervical stromal invasion (p < 0.0001). In univariate analysis, lymph node metastasis, parametrial invasion, presence of lymphovascular space invasion, and preoperative SUV{sub max} (uncategorized values) in the primary tumour were significantly associated with recurrence. However, in multivariate analysis, preoperative SUV{sub max} (p = 0.014, HR 1.178, 95% CI 1.034-1.342), age (p = 0.021, HR 0.87, 95% CI 0.772-0.980), and parametrial involvement (p = 0.040, HR 27.974, 95% CI 1.156-677.043) by primary tumour were significantly associated with recurrence. Preoperative FDG uptake by the primary tumour showed a significant association with recurrence in patients with uterine cervical cancer. (orig.)

    Twelve patients with locoregionally advanced uterine cervical cancer (IIIB: 10, IVA: 2) were treated with neoadjuvant chemotherapy consisting of bleomycin, ifosfamide, and nedaplatin (NAC-BIN) and full dose radical radiotherapy. NAC-BIN achieved one complete response and seven partial responses, for a response rate of 67%. Hematologic toxicity was the most common side effect. Five experienced grade 3{<=}leukopenia, and three had grade 3{<=}anemia. With the mean follow-up of 25 months (range: 9-52 months), nine of 12 patients developed recurrence. Eight had pelvic recurrence alone, and one had both pelvic recurrence and distant metastases. The 2-year pelvic control rate, disease-free survival rate (DFS), and absolute survival rate (AS) were 25%, 25%, and 42%, respectively. The 2-year DFS and AS for patients who responded well to NAC-BIN (CR+PR) was 38% and 63%, whereas for those with a poor response (NC) were 0%. From these results, we consider that preoperative NAC-BIN should not be indicated for patients with unresectable stage (stage III{<=}) uterine cervical cancer, because poor responders must subsequently be treated with definitive radiotherapy and may suffer poor prognosis.

  3. Radiotherapy combined with intracavitary irradiation for uterine cervical cancer. Study of survival rate, patterns of recurrence and complication

    International Nuclear Information System (INIS)

    Survival rates and patterns of recurrence in 137 patients with uterine cervical cancer were determined. These patients were treated by radiotherapy with high-dose rate intracavitary irradiation using remote afterloading system (RALS) at Kyorin University Hospital from Oct. 1987 to Dec. 1992. Age range was from 29 to 87 years. According to clinical staging of UICC, stages I, II, III, and IV were observed in 29, 62, 33, and 13 cases respectively. Cumulative 5-year survival rate of all cases was 72%. Cumulative 5-year survival rates were 100% for stage I, 81% for stage II, 38% for stage III, and 27% for stage IV. Cumulative 5-year survival rates of the postoperative radiotherapy and radical radiotherapy groups were 75% and 90% respectively. There was significant difference of survival rates between the postoperative radiotherapy group and the radical radiotherapy group. As patterns of recurrence, extrapelvic metastasis was more frequent than local recurrence. In stages II and III, recurrent patterns were extrapelvic matastasis in most cases. Of 18 cases with extrapelvic metastasis, there were 10 cases of paraaortic lymph node metastasis. With increase in the control rate of parraortic lymph node metastasis, survival rate of patients with uterine cervical cancer increased. Four of 5 cases with local recurrence controled by intracavitary irradiation is effective for local recurrence control. Rectal and bladder complications following radiotherapy were observed in 25 cases. However, all cases with complication after radiotherapy were treated conservatively, excluding 1 case (vasicorectal fistula). (author)

  4. Tumor volume and uterine body invasion assessed by MRI for prediction of outcome in cervical carcinoma treated with concurrent chemotherapy and radiotherapy

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the prognostic significance of primary tumor volume and uterine body invasion assessed by pre-treatment MRI for uterine cervical cancer patient treated with concurrent chemotherapy and radiotherapy. A retrospective analysis of 106 patients with IB-IIIB cervical carcinoma was performed. Potential prognostic factors were stage, clinical tumor diameter, histology, age, pelvic lymph node, vaginal extension, parametrial invasion, tumor volume and uterine body invasion status. Multivariate analyses were performed to identify the prognostic factor for overall survival (OS) and disease-free survival (DFS). The 5-year OS, DFS rate were 59.7 and 56.6%. Using multivariate analyses, a large tumor volume (?30 ml; P=0.012) and uterine body invasion (P=0.020) and positive pelvic lymph node (LN) enlargement (P=0.040) showed a significantly unfavorable influence on OS. Using these three factors, patients were divided into four subgroups: the OS rates of patients with risk 0 (volume<30 ml, no uterine body invasion, and negative LN), risk 1 (one of these three factors), risk 2 (two of these three factors) and risk 3 (volume?30 ml, uterine body invasion, and positive LN) were 96.3, 77.5, 53.0 and 14.8%, respectively (P<0.0001). Tumor volume and uterine body invasion determined by MRI were significant prognostic factors for patients with cervical carcinoma. Pelvic lymph node enlargement diagnosed by CT also proved to be a significant prognostic factor in OS. Using these three parameters, we devised a practical and effective model to predict OS.

  5. Neoadjuvant Intra-Arterial Chemotherapy for Locally Advanced Uterine Cervical Cancer: Clinical Efficacy and Factors Influencing Response

    International Nuclear Information System (INIS)

    Purpose: To evaluate the effects of neoadjuvant intra-arterial chemotherapy (NAIC) for locally advanced uterine cervical cancer, and to analyze factors influencing the response to the chemotherapy. Methods: Thirty-four patients with invasive cervical cancer more than 4 cm in diameter were enrolled in this study. NAIC was performed using cisplatin-based regimens. The response was assessed by magnetic resonance imaging (MRI) and examination of surgical specimens. Pretreatment factors involved in the response to NAIC were evaluated and the relationship between the factors and the prognosis was assessed. Results:Clinical response was achieved in 28 (82%) patients. Thirty-one of 49 invasions in the parametrial halves disappeared. Seventeen of 28 lymphnode swellings responded to NAIC. Six of the 14 stage III patients became operable. In the 19 surgical cases, pathologically complete responses were found in four. Twenty-eight of the 38 parametrial halves were free from cancer. No lymph node metastases were found in eight patients. Initial tumor volume was found to be an independent, significant determining factor of the response to NAIC. Patients with initial tumor volumes less than 80 cm3 had a significantly better estimated 5-year disease-free survival rate compared with those with larger tumors. Conclusion: NAIC for locally advanced cervical cancer is useful for preoperative tumor reduction.Tumor volume is a significant determining factor for the response to NAIC

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

  8. Long-term outcomes of intracavitary hyperthermia in combination with radiotherapy for locally advanced uterine cervical cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the long-term clinical efficacy and toxicities of combined intracavitary hyperthermia and radiotherapy for locally advanced uterine cervical cancer. Methods: 310 patients with locally advanced uterine cervical cancer were assigned into intracavitary hyperthermia + radiotherapy group(TRT, 181 patients) and external-beam radiotherapy + traditional intracavitary radiation group (RT,129 patients). The external-beam radiotherapy were given with 60Co ?-ray or 6-8 MV X-ray in traditional fractionation. In TRT group, radiotherapy was 40 Gy using the anterior-posterior pelvic fields and additional 20-25 Gy using the lateral fields. Hyperthermia was delivered by the 915 MHz microwave hyperthermia device within 15-60 min after external radiotherapy for 10-12 times(40 min each time, 1-2 times per week). The temperature of tumor surface was 46-47 degree C. In the RT group, the external-beam radiotherapy of 40 Gy was delivered using the anterior-posterior pelvic fields. The intracavity radiotherapy of radium was delivered before 1989, with 50 mg radium in the vagina and 30 mg in uterine cavity for 24 hours, weekly for 3 times to a total dose of 7200 mg·h. After 1989, intracavity radiotherapy of 192Ir was delivered to a total dose of 30-36 Gy to point A in 5-6 Gy fractions, 2 fractions per week. Results: The 5-year survival of patients in TRT group and RT group was 67.4% versus 52.1% for stage II disease (?2=7.55, P=0.006), and 60.0% versus 32.3% for stage III (?2=7.06, P=0.007). The 10-year survival was 46.5% versus 42.6% for stage II (?2=3.90, P=0.058), and 43.7% versus 20.6% for stage III (?2=17.28, P=0.000). Cox regression analysis showed that the tumor stage(P=0.023) and intracavitary hyperthermia (P=0.019) were prognostic factors. According to the RTOG criteria, the rate of mild to moderate late side effects of rectum and bladder in TRT and RT group was 17.7% and 33.1%, respectively (?2=9.18, P=0.002). Rectovaginal fistula was developed in 5 patients (3.9%) in RT group and 1 patient (0.6%) in TRT group (?2= 4.38,P=0.036). Conclusions: The long-term survival of patients with stage III uterine cervical cancer is better of TRT group than RT group. The TRT is well tolerated and the late toxicity rate is obviously low. it is necessary to carry out large randomized clinical trials to confirm these outcomes. (authors)

  9. A case of radiation-induced cutaneous angiosarcoma 15 years after simultaneously occurring uterine cervical and gastric cancers discovered by autopsy

    International Nuclear Information System (INIS)

    A case of cutaneous angiosarcoma in the skin on the left hip previously irradiated for cervical uterine squamous cell carcinoma is discovered by autopsy. The patient, a 79-year-old woman, at age 64 had been then underwent radiotherapy for the cervical uterine carcinoma. A total dose of 50 Gy was administrated. At 79 years of age, she noticed multiple purple black nodular skin lesions on the left hip and thigh. She was hospitalized for 8 days, but her general condition rapidly deteriorated and she died. An autopsy revealed that the skin lesion was composed of atypical polygonal cell proliferation forming irregularly anastomosing vascularity, together with hemorrhage and necrosis. The tumor cells were positive for both CD34 and factor 8-related antigens. The final diagnosis was angiosarcoma. (author)

  10. The value of prognostic factors for uterine cervical cancer patients treated with irradiation alone

    International Nuclear Information System (INIS)

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

    Full Text Available Infection with genital herpes simplex virus (HSV remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

  15. Uterine cervical melanoma presenting with rapid progression detected by PET/CT

    International Nuclear Information System (INIS)

    Malignant melanoma of the uterine cervix is a rare extracutaneous melanoma which develops aggressively and is associated with a bleak prognosis. To our knowledge, no prior published reports have discussed the role of 18F-FDG positron emission tomography/computed tomography (PET/CT) in managing this disease. Our case study involved a 66-year-old woman with a malignant melanoma of the uterine cervix. The patient received PET/CT that identified metastases and lesions which had not been detected from her MRI. Serial PET/CT elucidated that the disease was initially limited to the pelvis, but then metastasized to the abdominal para-aortic lymph nodes, followed by extensive metastases to the brain, lungs, breast, supraclavicular, neck, and other abdominal lymph nodes, as observed at 6-month follow-up. PET/CT was used to complement conventional anatomic imaging modalities, and provided a novel modality for whole body screening. Visualization of the metabolic activity of indeterminate lesions may help in staging, re-staging, treatment planning, and prognostic prediction for patients with this rare disease

  17. Three cases of colorectal cancer after radiotherapy for the uterine cervical cancer

    International Nuclear Information System (INIS)

    Three cases of colorectal cancer that developed after radiotherapy for cervical cancer are reported. In all cases. the pathology of the initial cancers was squamous cell carcinoma, while that of the second cancer was adenocarcinoma. The latency period was more than 5 years in each case. There was no significant difference between observed number and expected number in the incidences of colorectal cancer. Long-term follow-up procedures are necessary because radiation may contribute to the induction of colorectal cancer. (author)

  18. A consensus-based guideline defining clinical target volume for primary disease in external beam radiotherapy for intact uterine cervical cancer

    International Nuclear Information System (INIS)

    The objective of this study was to develop a consensus-based guideline to define clinical target volume for primary disease (clinical target volume primary) in external beam radiotherapy for intact uterine cervical cancer. The working subgroup of the Japan Clinical Oncology Group (JCOG) Radiation Therapy Study Group began developing a guideline for primary clinical target volume in November 2009. The group consisted of 10 radiation oncologists and 2 gynecologic oncologists. The process started with comparing the contouring on computed tomographic images of actual cervical cancer cases among the members. This was followed by a comprehensive literature review that included primary research articles and textbooks as well as information on surgical procedures. Extensive discussion occurred in face-to-face meetings (three occasions) and frequent e-mail communications until a consensus was reached. The working subgroup reached a consensus on the definition for the clinical target volume primary. The clinical target volume primary consists of the gross tumor volume, uterine cervix, uterine corpus, parametrium, vagina and ovaries. Definitions for these component structures were determined. Anatomical boundaries in all directions were defined for the parametrium. Examples delineating these boundaries were prepared for the posterior border of the parametrium for various clinical situations (id est (i.e.) central tumor bulk, degree of parametrial involvement). A consensus-based guideline defining the clinical target volume primary was developed for external beam radiotherapy for intact uterine cervical cancer. This guideline will serve as a template for radiotherapy protocols in future clinical trials. It may also be used in actual clinical practice in the setting of highly precise external beam radiotherapy, including intensity-modulated radiotherapy. (author)

  19. Role of Sentinel Lymph Node in Early Stage of Uterine Cervical Cancer

    Directory of Open Access Journals (Sweden)

    Full Text Available Cervical cancer is currently the second most common form of neoplasia worldwide and third in the female population. Dissemination can occur directly (isthmus, parametrium, vagina, urinary bladder and/or rectum, through the lymphatic system (parametrium, internal iliac, external iliac, common iliac, obturator lymph nodes and rarely in the inferior gluteus, superior gluteus, superior rectum, sacrum, aortic lymph nodes and through the circulatory system (lung, mediastinum, bones, liver. The risk of pelvic lymph nodes invasion in stage IB (FIGO is 9-17%. The standard surgical treatment, for stages IA2-IIA, is radical hysterectomy with pelvic lymphadenectomy. The risk of intraoperative (vessel or nerve damage or postoperative complications (lymphedema is not negligible. The sentinel node concept refers to the first lymph node in which the cancerous lymphatic drainage takes place. This idea has radically changed the therapeutic approach in the treatment of breast cancer and melanoma. In cervical cancers, this technique is 92% accurate with only an 8% false negative rate. Currently, the sentinel node protocol is not included in the standard treatment for cervical cancer because certain issues need to be addressed (the sensitivity of the frozen section examination, the pathologist’s subjectivity, the uniformity of the protocol, the surgical experience, the size of the tumor.

  20. Optimal overall treatment time in fractionated radiotherapy for head and neck cancers, esophageal cancer, and uterine cervical cancer

    International Nuclear Information System (INIS)

    The effects of overall treatment time (OTT) on local control of radiation therapy (RT) were evaluated to consider optimal OTT in RT. Local control probabilities and acute and late toxicities of esophageal cancer (Stages I-III), glottic laryngeal cancer (Stage I), and uterine cervical cancer (Stage III) treated at Kyoto University Hospital and its affiliated hospitals were analyzed in relation to OTT. For these tumors, local control probabilities decreased when OTT increased. In the multivariate analyses for esophageal cancer and laryngeal cancer, OTT was a significant variable for local control. Only a 1-week interruption of RT due to holidays resulted in a significant reduction of local control probability for T1 glottic tumors. On the other hand, there was no significant difference in local control rates between OTT of 4 weeks and 6 weeks for esophageal cancer. For complications, acute and late toxicities increased when OTT was reduced by accelerated hyperfractionated RT for esophageal cancer. In conclusion, OTT should be kept as short as possible within the limits of tolerance of normal tissues and the patients. We consider that RT must be delivered in the range of 66 to 70 Gy in 6 weeks to obtain optimal local control with minimum complications. (author). 52 refs

  1. A nationwide survey regarding the sedation methods of intracavitary brachytherapy for uterine cervical cancer

    International Nuclear Information System (INIS)

    We conducted a nationwide survey about the sedation methods of intracavitary brachytherapy for cervical cancer. Responses were obtained from 141/171 institutions (84%). Intravenous conscious sedation or more intensive sedation was used in 39%. Most of the radiation oncologists especially who uses weaker medication felt that their sedation methods were not adequate enough for some patients. The frequent reasons for not using more intensive sedation included the lack of manpower and concerns about safety. The establishment of safe and adequate sedative management system is required.

    Full Text Available Although in Colombia screening programs of cervical cancer have achieved high levelsof coverage, cervical cancer has the first places in incidence and mortality. There isthe need to identify factors influencing it, among them is to investigate the level ofawareness of women about the screening test, their attitudes to screening and itspractices. For this we made a survey of 505 women 13 to 60 years who have had sexual life, living in the cities of Cartagena and Sincelejo (Colombia.The results showthat virtually all women have knowledge of cervical cytology, 94.5% of women havemade at least once. This percentage is higher in the range of 40 to 60 years where itreaches 99% in younger women this percentage decrease. In defining its usefulness,only 73.8% responded accurately. 50% reported unpleasant aspects related to themaking of the cytology, such as fear, and fear of a cancer diagnosis. A fail to rememberis the main factor for not claiming the results.These data show that the percentage ofwomen with sexual life that ignores the usefulness of cytology or never have practicedis minimal, which leads to the conclusion that ineffective screening programs to reducecervical cancer rates depends on other factors that should be investigated.RESUMEN:Aunque en Colombia los programas de prevención del cáncer de cérvix han alcanzadoaltos niveles de cobertura, todavía este ocupa los primeros lugares en incidencia ymortalidad.

  7. Uterine cervical cancer: treatment with megavoltage radiation results and afterloading intracavitary techniques

    International Nuclear Information System (INIS)

    Results were evaluated for 651 consecutive patients with invasive cancer of the intact uterine cervix. From 1963 through 1967 319 patients were treated primarily with the older Los Angeles County Hospital system of orthovoltage radiation and intracavitary radium therapy. Thereafter, 1968 to 1974, 332 patients were treated primarily with a newer modified M. D. Anderson Tumor Institute system of megavoltage radiation and afterloading intracavitary radium therapy. Age distribution and histology were similar for both groups, but clinical stage was slightly more advanced for patients treated earlier. Crude and net 5 year survival rates were 36% and 49% for the early group and 54% and 67% for the later group. Net 5 year survival rates for the earlier group by stage were: stage 1, 74%; II, 62%; III, 23%; and IV, 6%. Survival rates for the later group were: I, 81%; II, 76%; III, 50%; and IV, 15%. We believe this improvement can be attributed to more effective intracavitary radium therapy for handling local cancer and to delivery of cancericidal doses of radiation to regional nodes with the megavoltage radiation apparatus, as well as to the greater cooperative efforts put forth in the management of County Hospital patients

Baseado nos achados histopatológicos, a freqüência de HSIL/CA foi 3% (IC95%: 1,8-4,6. Houve um caso de câncer invasivo. A cada nova gestação, a chance de HSIL/CA aumentava 2,2 vezes (IC95%: 1,1-4,4. A idade também esteve associada com este resultado (OR = 2,0; IC95%: 1,2-3,4, dobrando a cada ano de idade a chance de adquirir este nível da doença. A freqüência de lesões cervicais intra-epiteliais sugere a importância de incluir adolescentes sexualmente ativas nos programas de prevenção do câncer cervical, com o objetivo de detectar e assegurar o tratamento precoce destas lesões.

  10. RAPIDARC (RA) in the uterine cervical cancer; dosimetric gain vs 3D-Crt

    International Nuclear Information System (INIS)

    This work aims to quantitatively assess RAPIDARC (RA) treatments versus three dimensional-Conformal Radiation Therapy with field to field technique (3D-Crt-Fin F). 11 patients with cervical cancer treated at our institution radically or adjuvant clinical stages I-III B were evaluated. The prescribed dose was 50 Gy (2 Gy / Fr). The RA plans consisted of two isocentric complete arcs and conformational plans of 4 isocentric fields (previous, subsequent, right side and left side) with 3D-Crt-Fin F technique; both cases carried out ??in the Eclipse version 10 planner with calculation algorithm analytical anisotropic algorithm (AAA) and volumetric optimization software (for VMAT plans). Homogeneity indices (Hi), conformity indices (CI) Sigma indices (S-Index), monitor units (MU) and the time required for each treatment were compared. The mean age was 52 years (32-65) of the 11 patients 9 were clinical stages I-II B. The Hi varied from 0.052 for RA to 0.163 for 3D-Crt-Fin F (p = 0.009), and the CI between 1.005 and 1.35 (p = 0.26), the S-index from 1.2 to 3.7 (p = 0.001) and the H-index of 1.08 to 1.15 (p = 0.24). All dose limits in risk organs were met with a significant difference in the RA plans versus 3D-Crt-Fin F. In patients with cervical cancer the treatment plans quality with the indices aforementioned seems to be better with the RA technique, being observed a significant reduction of radiation to surrounding organs.

  11. Pre-treatment diffusion-weighted MR imaging for predicting tumor recurrence in uterine cervical cancer treated with concurrent chemoradiation: Value of histogram analysis of apparent diffusion coefficients

    International Nuclear Information System (INIS)

    To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated with chemoradiation therapy (CRT). Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two patients (mean age, 56 ± 14 years) with biopsy-proven uterine cervical squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging with a 3.0 T magnetic resonance scanner and concurrent CRT were included. All patients were followed-up for more than 6 months (mean, 36.4 ± 11.9 months; range 9.0-52.8 months) after completion of CRT. Baseline ADC parameters (mean ADC, 25th percentile, 50th percentile, and 75th percentile ADC values) of tumors were calculated and compared between the recurrence and no recurrence groups. In the recurrence group, the mean ADC and 75th percentile ADC values of tumors were significantly higher than those of the no recurrence group (p = 0.043 and p = 0.008, respectively). In multivariate analysis, the 75th percentile ADC value of tumors was a significant predictor for tumor recurrence (p = 0.009; hazard ratio, 1.319). When the cut-off value of the 75th percentile ADC (0.936 x 10-3 mm2/sec) was used, the overall recurrence free survival rate above the cut-off value was significantly lower than that below the cut-off value (51.9% vs. 91.7%, p = 0.003, log-rank test). Pre-CRT ADC histogram analysis may serve as a biomarker for predicting tumor recurrence in patients with uterine cervical cancer treated with CRT.

    Using integrated PET/CT, we evaluated the prognostic relevance in uterine cervical cancer of preoperative pelvic lymph node (LN) [{sup 18}F]FDG uptake. Patients with FIGO stage IB to IIA uterine cervical cancer were imaged with FDG PET/CT before radical surgery. We used Cox proportional hazards regression to examine the relationship between recurrence and the FDG maximum standardized uptake value (SUV{sub max}) in the pelvic LN (SUV{sub LN}) on PET/CT. Clinical data, treatment modalities, and results in 130 eligible patients were reviewed. The median postsurgical follow-up was 34 months (range 6 to 109 months). Receiver operating characteristic analysis identified SUV{sub LN} 2.36 as the most significant cut-off value for predicting recurrence. SUV{sub LN} was correlated with SUV{sub tumour} (P = 0.002), primary tumour size (P = 0.004), and parametrial invasion (P = 0.013). Univariate analyses showed significant associations between recurrence and SUV{sub LN} (P = 0.001), SUV{sub tumour} (P = 0.007), pelvic LN metastasis (P = 0.002), parametrial invasion (P < 0.001), primary tumour size (P = 0.007), suspected LN metastasis on MRI (P = 0.024), and FIGO stage (P = 0.026). Multivariate analysis identified SUV{sub LN} (P = 0.013, hazard ratio, HR, 4.447, 95 % confidence interval, CI, 1.379 - 14.343) and parametrial invasion (P = 0.013, HR 6.728, 95 % CI 1.497 - 30.235) as independent risk factors for recurrence. Patients with SUV{sub LN} ?2.36 and SUV{sub LN} <2.36 differed significantly in terms of recurrence (HR 15.20, P < 0.001). Preoperative pelvic LN FDG uptake showed a strong significant association with uterine cervical cancer recurrence. (orig.)

    Using integrated PET/CT, we evaluated the prognostic relevance in uterine cervical cancer of preoperative pelvic lymph node (LN) [18F]FDG uptake. Patients with FIGO stage IB to IIA uterine cervical cancer were imaged with FDG PET/CT before radical surgery. We used Cox proportional hazards regression to examine the relationship between recurrence and the FDG maximum standardized uptake value (SUVmax) in the pelvic LN (SUVLN) on PET/CT. Clinical data, treatment modalities, and results in 130 eligible patients were reviewed. The median postsurgical follow-up was 34 months (range 6 to 109 months). Receiver operating characteristic analysis identified SUVLN 2.36 as the most significant cut-off value for predicting recurrence. SUVLN was correlated with SUVtumour (P = 0.002), primary tumour size (P = 0.004), and parametrial invasion (P = 0.013). Univariate analyses showed significant associations between recurrence and SUVLN (P = 0.001), SUVtumour (P = 0.007), pelvic LN metastasis (P = 0.002), parametrial invasion (P LN (P = 0.013, hazard ratio, HR, 4.447, 95 % confidence interval, CI, 1.379 - 14.343) and parametrial invasion (P = 0.013, HR 6.728, 95 % CI 1.497 - 30.235) as independent risk factors for recurrence. Patients with SUVLN ?2.36 and SUVLN <2.36 differed significantly in terms of recurrence (HR 15.20, P < 0.001). Preoperative pelvic LN FDG uptake showed a strong significant association with uterine cervical cancer recurrence. (orig.)

  14. Do clinicians and patients agree regarding symptoms? A comparison after definitive radiochemotherapy in 223 uterine cervical cancer patients

    International Nuclear Information System (INIS)

    Background: In clinical cancer research of morbidity, low associations between clinician-assessed toxicity/morbidity and patient-reported symptoms are consistently described in the literature. While morbidity grading systems are supposed to follow more or less objective criteria, patient reported symptoms inherently are based on a subjective self-evaluation of the impact on quality of life. The aim of this study was to focus on major discrepancies with high clinical relevance and to evaluate its impact with regard to underreporting of morbidity. Material and methods: Early morbidity assessed by clinicians with CTCAEv.3 and patient reported quality of life (EORTC-QLQ-C30/CX24) were compared regarding 12 overlapping symptoms in 223 patients with uterine cervical cancer 3 months after definitive radio(chemo)therapy in the ongoing EMBRACE study. Mismatches showing discrepancies between both grading systems were classified, if patients reported substantial symptoms (quite a bit/very much) and CTCAE grading was rated G0. Results: In total, 360 substantial symptoms were reported by patients by EORTC-QLQ; 159 (44%) of those were not recognized by CTCAE. Symptoms with the highest occurrence of mismatches overall are urinary frequency, fatigue, and insomnia. Large institutional differences were found, showing two centers with 4 vs. 71% of patients with at least one mismatch. Conclusion: Analysis of mismatches indicated a high risk of underestimation of early morbidity. Thus, nearly half of the patient-reported substantial symptoms were not recognized by CTCAE scoring (G0) 3 months after treatment. Prospective assessment of morbidity in clinical studies should, therefore, integrate patient reported symptoms to receive a complete and comprehensive picture. (orig.)

  16. Sizofiran augmented the capacity for interleukin-2 and interferon-? production in patients with uterine cervical cancer under pelvic radiotherapy

    International Nuclear Information System (INIS)

    The anti-tumor polysaccharide, sizoferan (SPG), is known as one of the effective biological modifiers which can mediate immunological reaction through a T cell activation pathway. We analyzed the effects of SPG on the production of interleukin-2 (IL-2) and interferon-? (IFN-?) on peripheral mononuclear cells (PMC) in 16 patients with uterine cervical cancer under primary pelvic irradiation. A dose of 20 mg/week of SPG was intramuscularly administered under radiotherapy to 10 patients, and 6 patients were treated by pelvic irradiation without any anti-tumor drugs as a control group. In the control group (pelvic radiotherapy alone), the abilities to produce IL-2 and IFN-? on PMC were markedly diminished at day 10 of irradiation and continued at a low level during radiotherapy, indicating even local irradiation on the lower abdomen can systematically suppress the immune system in a tumor bearing host. In contrast, the experimental group given a weekly injection of SPG showed enhanced productivity of both cytokines (129.5±53.9% (IL-2), 114.5±23.1% (IFN-?)) compared to that before radiotherapy (p<0.05). This augmentation of IL-2 productivity was relatively higher than that of IFN-?. These results suggest that SPG can augment the immunological response in vivo in the myelosuppressed patient under radiotherapy by activating T lymphocytes and macrophage through IL-2 and/or IFN-?. This positive effect of combination therapy with SPG and anti-tumor cytokines such as IL-2 and IFN-? may be a useful strategy for advanced cancer. (author)

  18. Long time effect of combination therapy with irradiation and balloon-occluded arterial infusion of anti-cancer drugs on uterine cervical cancer

    International Nuclear Information System (INIS)

    Long time effect of combination therapy with irradiation and balloon-occluded arterial infusion (BOAI) of anti-cancer drugs on uterine cervical cancer was estimated by retrospective analysis. All 73 cases received radiotherapy, while 39 cases were treated also with BOAI. Cisplatin, adriamycin and pepleomycin were administered by BOAI. In 44 stage III cases, patients with BOAI showed significantly better 5-year survival compared to radiation alone group (p=0.045). Multivariate analysis selected stage, blood hemoglobin content and BOAI as significant predictor of prognosis. No increase of late radiation damage to rectum or to urinary bladder was seen by combination therapy with BOAI. (author)

  19. Inappropriate cervical injection of radiotracer for sentinel node mapping in a uterine cervix cancer patient: importance of lymphoscintigraphy and blue dye injection

    Full Text Available Herein, we report a case of sentinel lymph node mapping in a uterine cervix cancer patient, referring to the nuclear medicine department of our institute. Lymphoscintigraphy images showed inappropriate intra?cervical injection of radiotracer. Blue dye technique was applied for sentinel lymph node mapping, using intra?cervical injection of methylene blue. Two blue/cold sentinel lymph nodes, with no pathological involvement, were intra?operatively identified, and the patient was spared pelvic lymph node dissection. The present case underscores the importance of lymphoscintigraphy imaging in sentinel lymph node mapping and demonstrates the added value of blue dye injection in selected patients. It is suggested that preoperative lymphoscintigraphy imaging be considered as an integral part of sentinel lymph node mapping in surgical oncology. Detailed results of lymphoscintigraphy images should be provided for surgeons prior to surgery, and in case the sentinel lymph nodes are not visualized, use of blue dye for sentinel node mapping should be encouraged.

    Objective. To characterize the radiologic features of postradiation sarcomas arising in the pelvic bones following treatment for uterine cervical carcinoma. Design and patients. Five patients who developed postradiation sarcomas in the pelvic bones following radiation therapy for carcinoma of the uterine cervix within the irradiated field were evaluated. Pelvic radiographs, computed tomography (CT) and magnetic resonance (MR) imaging were undertaken in all patients. Histologic confirmation of the tumor type was obtained. Results. Three patients whose tumors were characterized as an osteosarcoma, an angiosarcoma and a malignant fibrous histiocytoma (MFH) showed a large round or oval mass mainly in the sacroiliac joint which extended into the posterior gluteal soft tissues. In a fourth patient an osteosarcoma developed in the central ilium extending widely into the soft tissues both anteriorly and posteriorly, with calcified areas within the extraosseous mass. The fifth patient had a MFH which showed osteolytic destruction of the cortex of the acetabulum, and minimal soft tissue extension. There were no specific features or signal intensity changes on MR imaging to differentiate these cases from primary sarcomas. Conclusion. Postradiation sarcoma must be considered in patients with uterine carcinoma when a soft tissue mass is seen in the previously irradiated field, especially if the mass is posterior to the sacroiliac joint and the latent period is more than 5 years.

    Full Text Available The association of human papilloma virus (HPV infection and cervical intraepithelial neoplasia (CIN is well known. Interaction of HPV proteins with cellular regulatory proteins leads to up regulation of p16INK4A. The aim of this study was to evaluate p16INK4A protein as a biomarker for CIN lesions and squamous cell carcinoma on biopsy specimens of patients who underwent biopsy of the uterine cervix due to abnormal cytological finding.The authors analyzed biopsies from 50 patients with CIN and invasive squamous cell carcinoma of the uterine cervix. Expression of p16INK4A in CIN and invasive squamous cell carcinoma was immunohistochemically analyzed by using monoclonal anti-p16INK4A antibody.A total of 50 patients with CIN and invasive squamous cell carcinoma of the uterine cervix (mean age 40.2±11.5 years, range 20-74 years were analyzed. CIN I lesions were found in 27 (54%, CIN II/CIN III lesions in 9 (18%, and invasive squamous cell carcinoma in 14 (28% patients. Differences in the expression of p16INK4A between CIN I, CIN II/CIN III and squamous cell carcinoma were statistically significant (p<0.0001. Expression of p16INK4A showed low sensitivity (7%, specificity (8%, positive predictive value (8%, and negative predictive value (7% for CIN I. Sensitivity, specificity, positive predictive value, and negative predictive value of p16INK4A were 78%, 61%, 30%, and 93% for CIN II/CIN III, and 100%, 75%, 61%, and 100% for squamous cell carcinoma, respectively.Results of this study suggest that p16INK4A protein may be a sensitive biomarker for CIN II/CIN III lesions and invasive squamous cell carcinoma of the uterine cervix.

    BACKGROUND AND PURPOSE: This study evaluates the impact of MRI guided adaptive brachytherapy (BT) on uterine corpus dose. MATERIAL AND METHODS: 84 patients with median follow-up of 18 months were analysed. MRI based BT was done according to GEC-ESTRO guidelines. Non-involved uterine corpus at the time of BT was contoured and the uterine corpus dose (D90 and D98) was evaluated for (1) standard loading pattern with source loading to the tip of the tandem and (2) optimised dose plan. Tandem lengths and heights of the 85 Gy isodose were recorded. RESULTS: Dose optimisation resulted in a reduction of active tandem length of 0.4±0.4 cm leading to lowering the D90 to the non-involved uterine corpus from 63.8±9.5 Gy to 56.7±7.5 Gy EQD2 (p<0.0001). Mean active tandem length was 5.0±1.0 cm, and the height of the 85 Gy isodose was 5.7±1.0 cm in optimised plans. CONCLUSIONS: MRI guided dose optimisation lowered the dose to the uterine corpus. However, a total EBRT+BT dose larger than 50 Gy was obtained in 99% of patients. Assuming that 45-50 Gy is sufficient to eradicate microscopic disease, the lowering of uterus corpus dose is not expected to induce additional uterine corpus recurrences in the setting of MRI guided adaptive BT. This hypothesis should be tested in a larger number of patients as e.g. the EMBRACE study.

Patients with recurrent uterine cervical cancer stages IB1 and IIA who had been treated with primary surgical resection were included. Kaplan-Meir survival curves were constructed. Results: 609 radical hysterectomies type II were performed; 53 (8.7%) had a recurrence. Mean age at diagnosis of recurrence was 44.5 years; mean time from surgery to recurrence was 18.9 months, and the most common site for recurrence was distant recurrence (415%), followed by central recurrence and pelvic recurrence. Site of recurrence and surgical margins had statistical association with time to recurrence. The most frequent salvage therapy was radiotherapy (45%). Mean survival time after recurrence was 26.9 months, and survival rate at 5 years was 9.4%. Conclusions: Recurrent uterine cervical cancer is not frequent, its affects young females causing distant metastasis mainly. Time to recurrence is shorter when recurrence is central and surgical margins are involved. Survival time after recurrence in patients treated surgically is short.

    Full Text Available En Cuba, al igual que en el resto de los países occidentales, el cáncer cérvico-uterino se encuentra en segundo lugar de morbilidad oncológica en mujeres de 20 a 30 años; y a ctualmente está considerado como una infección de transmisión sexual. Hay estudios que revelan información deficiente por parte de los adolescentes en cuanto a las infecciones de transmisión sexual y sus consecuencias. Es por ello, que en el período comprendido entre febrero y noviembre de 2009 se realizó una investigación descriptiva con el objetivo de identificar los conocimientos sobre prevención del cáncer cérvico-uterino en los adolescentes de la ESBU Manuel Sanguily, del municipio Matanzas. El universo estuvo integrado por los alumnos de noveno grado, y para la selección de la muestra se utilizó un muestreo probabilístico por conglomerados monoetápico. Se aplicó un cuestionario, cuyos resultados relevantes indicaron que los varones iniciaron sus primeras relaciones sexuales a los 13 años y las hembras a las edades de 13 y 14 años, representado un 57,1 % y 50 %, respectivamente. Solo el 12,7 % de los adolescentes identificó al virus del papiloma humano como factor de riesgo en la génesis del cáncer cérvico-uterino. El bajo nivel de conocimientos para la prevención de este tipo de cáncer predominó en el 92,7 % de la muestra. Se concluye que en el grupo de adolescentes estudiados, lo más frecuente fue el inicio temprano de las relaciones sexuales, tanto para varones como para hembras, aunque estas últimas representaron solo el 10 %. Se identificó desconocimiento sobre el virus del papiloma humano como agente causal de esta morbilidad, y pobre conocimiento sobre cómo prevenirlo.In Cuba, as in the rest of the Western countries, the cervical-uterine cancer is in the second place of oncologic morbidity in 20-to-30 years-old women; currently it is considered a sexually transmitted infection. There are some studies revealing deficient information on the part of the teenagers as for the sexually transmitted diseases and theirs consequences. That is why, in the period from February to November 2009 we carried out a descriptive investigation with the objective of identifying the knowledge on the prevention of the cervical-uterine cancer the students of the Secondary School Manuel Sanguily, Municipality of Matanzas, have. The universe was formed by the nine grade students, and to select the sample we used a probabilistic sampling by mono-stage conglomerates. A questionnaire was applied and the results indicated that the males began their first sexual relationships to the 13 years and the females to the ages of 13 and 14 years, representing 57,1 % and 50 %, respectively. Only 12,7 % of the teenagers identified the human papilloma virus as a risk factor in the genesis of the cervical-uterine cancer. The low level of knowledge for the prevention of this kind of cancer prevailed in 92,7 % of the sample. We concluded that in the group of teenagers we studied, the most frequent fact was that they began early having sexual relationships, both boys and girls, although the last ones represented only 10 %. We identified ignorance on the human papilloma virus and poor knowledge about how to prevent it as the casual agent of this morbidity.

  11. Value of FDG-PET vs MRI/CT in detection and staging of early uterine cervical cancer

    International Nuclear Information System (INIS)

    This prospective study was performed to define the efficiency of FDG-PET in detecting primaries and in preoperatively assessing lymph node metastases of cervical cancer. Forty one patients with cervical cancer were investigated with PET (370 MBq F-18-FDG, Siemens ECAT EXACT HR+, visual evaluation) and MRI prior radical hysterectomy with pelvic, and additionally 12 cases paraortal, lymphadenectomies. Histopathological evaluation verified in all cases the evidence of cervical cancer except in one case, where the tumor was completely removed by conisation procedure. Sensitivity of PET and MRI were 95% and 85%, respectively. In 16/82 pelvic lymph node sites metastases were histologically detected (7 x micrometastases). Sensitivity, specificity, positive positive and negative predictive value were 50%, 85%, 44% and 88% for PET and 31%, 90%, 40% and 86% for MRI. Out of the 12 cases with dissection of paraortal lymph nodes, metastases were found histologically in 3 cases. PET detected 2/3 truly with no false positive result while CT detected 0/3 cases with no false positive findings. It is concluded that PET can detect cervical cancer with high accuracy. The accuracy of PET and MRI was similar for detection of pelvic metastases. Both methods have limited sensitivity due to the high incidence of micrometastases. PET was more accurate than CT in detection of paraortal metastases

  13. Studies on serum protein fractions of patients with uterine cervical cancer undergoing radiotherapy. Relationship between changes in serum protein fractions and prognosis

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the correlation between changes in serum protein fractions and patient prognosis. The subjects were 84 patients with uterine cervical cancer treated with combined external pelvic irradiation and intracavitary irradiation using a remote afterloading system (RALS). Twenty one normal women served as controls. Serum levels of 23 protein components were determined before and after radiotherapy. All patients were followed up for 4 to 8 years after radiotherapy. Pretreatment serum levels of prealbumin (Prealb), ?2HS glycoprotein (?2HS), ?2-plasmin inhibitor (?2PI), transferrin (Tf), plasminogen (Pmg), albumin (Alb), IgM, and hemopexin (Hx) were significantly lower in the group of cervical cancer patients than the control group; and serum levels of ?1-antichymotrypsin (?1X), haptoglobin (Hp), C9, fibrinogen (Fib), ceruloplasmin (Cp), ?1-acid glycoprotein (?1AG), ?1-antitrypsin (?1AT), and C4 were elevated. At the completion of radiotherapy, HP, C4, and Fib levels were significantly lower than those before radiotherapy; Prealb, ?2HS, and ?2PI were elevated. In patients who survived 4 years and 8 years, pretreatment levels of Cp, ?1AG, Hp, and C9 were significantly reduced and Tf was elevated, as compared with those who died within 4 years. In those who survived more than 4 years, posttreatment levels of ?1AT, Hp, ?1X, Cp, and C9 were significantly reduced, although the serum level of C4 was elevated. Survival positively correlated with pretreatment levels of Tf, Pmg, and ?1AT, but negatively correlated with AT III, Cp, C1Inh, IgA, ?1AG, and C9. For posttreatment levels, it positively correlated with Pmg, C4, Prealb, Alb, ?2M, and Hp, but negatively correlated with Tf, ?2PI, AT III, ?1AT, C1Inh, C9, and IgA. (N.K.)

  14. A Dose-Volume Analysis of Magnetic Resonance Imaging-Aided High-Dose-Rate Image-Based Interstitial Brachytherapy for Uterine Cervical Cancer

    International Nuclear Information System (INIS)

    Purpose: To investigate the feasibility of our novel image-based high-dose-rate interstitial brachytherapy (HDR-ISBT) for uterine cervical cancer, we evaluated the dose-volume histogram (DVH) according to the recommendations of the Gynecological GEC-ESTRO Working Group for image-based intracavitary brachytherapy (ICBT). Methods and Materials: Between June 2005 and June 2007, 18 previously untreated cervical cancer patients were enrolled. We implanted magnetic resonance imaging (MRI)-available plastic applicators by our unique ambulatory technique. Total treatment doses were 30-36 Gy (6 Gy per fraction) combined with external beam radiotherapy (EBRT). Treatment plans were created based on planning computed tomography with MRI as a reference. DVHs of the high-risk clinical target volume (HR CTV), intermediate-risk CTV (IR CTV), and the bladder and rectum were calculated. Dose values were biologically normalized to equivalent doses in 2-Gy fractions (EQD2). Results: The median D90 (HR CTV) and D90 (IR CTV) per fraction were 6.8 Gy (range, 5.5-7.5) and 5.4 Gy (range, 4.2-6.3), respectively. The median V100 (HR CTV) and V100 (IR CTV) were 98.4% (range, 83-100) and 81.8% (range, 64-93.8), respectively. When the dose of EBRT was added, the median D90 and D100 of HR CTV were 80.6 Gy (range, 65.5-96.6) and 62.4 Gy (range, 49-83.2). The D2cc of the bladder was 62 Gy (range, 51.4-89) and of the rectum was 65.9 Gy (range, 48.9-76). Conclusions: Although the targets were advanced and difficult to treat effectively by ICBT, MRI-aided image-based ISBT showed favorable results for CTV and organs at risk compared with previously reported image-based ICBT results.

  15. Quality assurance in the prospective multi-institutional trial on definitive radiotherapy using high-dose-rate intracavitary brachytherapy for uterine cervical cancer. The individual case review

    International Nuclear Information System (INIS)

    The objective of this study was to assess compliance with the radiotherapy protocol of a multi-institutional prospective study (JAROG0401/JROSG04-2), which investigated the efficacy and toxicity of definitive radiotherapy using high-dose-rate intracavitary brachytherapy (HDR-ICBT) for early-stage uterine cervical cancer patients. Individual case reviews (ICRs) were performed on all 60 study participants. Radiotherapy data were submitted to the quality assurance (QA) committee, which performed ICRs on 16 QA items according to previously selected criteria. The items focused on quality of external beam radiotherapy (EBRT), HDR-ICBT and both. Each item was determined to be either acceptable or a deviation. The QA committee performed ICR three times as planned, two during the patient accrual and the final one just after the final patient accrued. The QA results of the first and second reviews were reported back to the investigators after each ICR. In 40 cases (67%), all 16 QA items were classified as acceptable. One deviation was found in 16 cases, two deviations were identified in 3 cases and three deviations were noted in 1 case. The most frequently observed deviation was missing the rules for determining point A (10 cases). The items described by quantitative values, such as prescribed doses, certain time intervals and overall treatment time, were well followed. The proportion of deviations gradually decreased during the ICR process. The present ICR demonstrated the favorable radiotherapy compliance with the JAROG0401/JROSG04-2 protocol. The QA process using ICRs can potentially be used to improve the quality of radiotherapy, including HDR-ICBT in the multi-institutional prospective studies for cervical cancer. (author)

    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.

    Absorbed dose determination is an important step for risk assessment related to an exposure to ionizing radiation. However, physical dosimetry cannot be always performed, principally in the case of retrospective estimates. In this context, the use of bioindicators (biological effects) has been proposed, which defines the so-called biological dosimetry. In particular, scoring of unstable chromosomes aberrations (dicentrics, centric rings and fragments) of peripheral blood lymphocytes, while is the most reliable biological method for estimating individual exposure to ionizing radiation. In this work, blood samples from 5 patients, with cervical uterine cancer, were evaluated after partial-body radiotherapy with a source of {sup 69} Co. For this, conventional cytogenetic method was employed, based on Giemsa coloration and fluorescence in situ hybridization, in order to correlate the frequency of unstable chromosome aberrations of blood lymphocytes with absorbed dose, as a result of the radiotherapy. A good agreement was observed between the frequency of chromosome aberrations scored and the values of dose previously calculated by physical dosimetry during patient's radiotherapy. The results presented in this work point out the importance of concerning analyses of unstable chromosome aberrations as biological dosimeter in the investigation of partial-body exposure to ionizing radiation.

  1. A case report of anal cancer preceded by perianal Paget's disease after irradiation for uterine cervical cancer and review of perianal Paget's disease in Japan

    International Nuclear Information System (INIS)

    The patient was a 59-year-old woman. Total hysterectomy and irradiation were performed for uterine cervical cancer 25 year previously. Paget's cells resembling signet ring cells were found in the epidermis, and anal cancer was present adjacent to them. The histological diagnosis of the anal cancer was mainly well differentiated adenocarcinoma, but mucinous carcinoma was present containing signet ring cells at sites contiguous with the anal glands, and lymphatic permeation was noted in the dermis. The cancer and the Paget's cells were both positive for PAS and alcian blue staining and were negative for PB/KOH/PAS staining. Furthermore, such findings as atypia of the glandular ducts and endoarteritis were detected in the underlying mucosa. Therefore, it was considered that this patient had anal cancer derived from the anal glands, that the Paget's cells were due to the intraepidermal extension of signet ring cells, and that the cancer may have been related to her previous irradiation. Reports of cancer of the rectum and anus complicated by Paget's lesion in Japan were reviewed and studied with regard to the histogenesis. It was concluded that peri-anal Paget's lesion had a close relationship with anal cancer derived from the anal glands. (author)

    Purpose: To investigate the effects of radiation on anorectal function in patients with carcinoma of the uterine cervix. Methods and Materials: Anorectal manometry was carried out on 24 patients (complication group) with late radiation proctitis. All of the manometric data from these patients were compared with those from 24 age-matched female volunteers (control group), in whom radiation treatment had not yet been performed. Results: Regardless of the severity of proctitis symptoms, 25% of patients demonstrated all their manometric data within the normal range, but 75% of patients exhibited one or more abnormal manometric parameters for sensory or motor functions. Six patients (25%) had an isolated sensory dysfunction, eight patients (33.3%) had an isolated motor dysfunction, and four patients (16.7%) had combined disturbances of both sensory and motor functions. The maximum tolerable volume, the minimal threshold volume, and the urgent volume in the complication group were significantly reduced compared with those in the control group. The mean squeeze pressure in the complication group was significantly reduced, whereas the mean resting pressure and anal sphincter length were unchanged. Conclusions: Physiologic changes of the anorectum in patients with late radiation proctitis seem to be caused by a variety of sensory and/or motor dysfunctions in which many different mechanisms are working together. The reduced rectal reservoir capacity and impaired sensory functions were crucial factors for functional disorder in such patients. In addition, radiation damage to the external anal sphincter muscle was considered to be an important cause of motor dysfunction

    The correlation between changes in serum protein fractions and patient prognosis was evaluated. The subjects were 84 patients with uterine cervical cancer treated with combined external pelvic irradiation and intracavitary irradiation using a remote afterloading system (RALS). Twenty one normal women served as controls. Serum levels of 23 protein components were determined before and after radiotherapy. All patients were followed up for 4 to 8 years after radiotherapy. Pretreatment serum levels of prealbumin (Prealb), [alpha][sub 2]HS glycoprotein ([alpha][sub 2]HS), [alpha][sub 2]-plasmin inhibitor ([alpha][sub 2]PI), transferrin (Tf), plasminogen (Pmg), albumin (Alb), IgM, and hemopexin (Hx) were significantly lower in the group of cervical cancer patients than the control group; and serum levels of [alpha][sub 1]-antichymotrypsin ([alpha][sub 1]X), haptoglobin (Hp), C9, fibrinogen (Fib), ceruloplasmin (Cp), [alpha][sub 1]-acid glycoprotein ([alpha][sub 1]AG), [alpha][sub 1]-antitrypsin ([alpha][sub 1]AT), and C4 were elevated. At the completion of radiotherapy, HP, C4, and Fib levels were significantly lower than those before radiotherapy; Prealb, [alpha][sub 2]HS, and [alpha][sub 2]PI were elevated. In patients who survived 4 years and 8 years, pretreatment levels of Cp, [alpha][sub 1]AG, Hp, and C9 were significantly reduced and Tf was elevated, as compared with those who died within 4 years. In those who survived more than 4 years, posttreatment levels of [alpha][sub 1]AT, Hp, [alpha][sub 1]X, Cp, and C9 were significantly reduced, although the serum level of C4 was elevated. Survival positively correlated with pretreatment levels of Tf, Pmg, and [alpha][sub 1]AT, but negatively correlated with AT III, Cp, C1Inh, IgA, [alpha][sub 1]AG, and C9. For posttreatment levels, it positively correlated with Pmg, C4, Prealb, Alb, [alpha][sub 2]M, and Hp, but negatively correlated with Tf, [alpha][sub 2]PI, AT III, [alpha][sub 1]AT, C1Inh, C9, and IgA.

  6. Changes in tumor oxygen tension during radiotherapy of uterine cervical cancer: relationships to changes in vascular density, cell density, and frequency of mitosis and apoptosis

    International Nuclear Information System (INIS)

    Purpose: Changes in oxygen tension (pO2) during the early phase of fractionated radiotherapy were studied in 22 patients with uterine cervical cancer. The aims were to investigate (a) whether possible changes in pO2 differed among and within tumors and (b) whether the changes could be attributed to changes in vascular density, cell density, and frequency of mitosis and apoptosis. Methods and Materials: The pO2 was measured polarographically in four regions of the tumors before treatment and after 2 weeks of radiotherapy. The vascular density, cell density, and frequency of mitosis and apoptosis were determined from biopsies taken from the tumor regions after each pO2 measurement. Results: The changes in pO2 during therapy differed among the tumors and were correlated to pO2 before treatment (p 2 and vice versa. The tumors with increased pO2 (n = 10) had a large decrease in cell density and a significant increase in apoptotic frequency. In contrast, the tumors with decreased pO2 (n = 10) had a smaller decrease in cell density (p = 0.014) and no significant increase in apoptotic frequency. Vascular density and mitotic frequency showed no change during therapy; however, vascular damage other than decreased vascular density was observed. Conclusion: These results indicate that the oxygenation of cervix tumors generally changes during the early phase of radiotherapy. The change depends on the balance between the factor leading to an increase and that leading to a decrease in oxygenation; i.e., decreased cell density and vascular damage, respectively. Increased apoptotic frequency may contribute to a large decrease in cell density and hence increased oxygenation during therapy

  7. Comparison of dose-volume analysis between standard Manchester plan and magnetic resonance image-based plan of intracavitary brachytherapy for uterine cervical cancer

    International Nuclear Information System (INIS)

    To investigate the feasibility of image-based intracavitary brachytherapy (IBICBT) for uterine cervical cancer, we evaluated the dose-volume histograms (DVHs) for the tumor and organs at risk (OARs) and compared results from the IBICBT plan and the standard Manchester system (Manchester plan) in eight patients as a simulation experiment. We performed magnetic resonance imaging (MRI) and computed tomography (CT) following MRI-adapted applicator insertion, then superimposed MR images on the planning CT images to describe the contours of high-risk clinical target volume (HR CTV) and OARs. The median volume of HR CTV was 29 cm3 (range, 21-61 cm3). Median D90 (HR CTV) and V100 (HR CTV) were 116.1% prescribed doses (PD) (90.0-150.8%) and 96.7% (84.2-100%), respectively, for the Manchester plan. In comparison, we confirmed that the median D90 (HR CTV) was 100% PD in the IBICBT plan for all patients. Mean D2cc (bladder) was 101.8% PD for the Manchester plan and 83.2% PD for the IBICBT plan. Mean D2cc (rectum) was 80.1% PD for the Manchester plan and 64.2% PD for the IBICBT plan. Mean D2cc (sigmoid) was 75% PD for the Manchester plan and 57.5% PD for the IBICBT plan. One patient with a large tumor (HR CTV, 61 cm3) showed lower D90 (HR CTV) with the Manchester plan than with the IBICBT plan. The Manchester plan may represent overtreatment for small tumors but insufficient dose distribution for larger tumors. The IBICBT plan could reduce OAR dosage while maintaining adequate tumor coverage. (author)

  8. Radiotherapy quality assurance of the Japanese gynecologic oncology group study (JGOG1066). A cooperative phase II study of concurrent chemoradiotherapy for uterine cervical cancer

    International Nuclear Information System (INIS)

    The background of this study was to assess radiotherapy protocol compliance in a multi-institutional phase II study of concurrent chemoradiotherapy for patients with locally advanced cancer of the uterine cervix (JGOG1066). For study protocol development, various radiotherapy parameters were examined and consensus was reached by Japanese radiation oncologists with cervical cancer treatment expertise. Quality assurance (QA) was also discussed and included in the protocol. A credentialing process was used to select institutions for participation in the study. Individual case reviews referring to 18 QA items were undertaken for each patient. Radiotherapy data were submitted to the Japanese Gynecologic Oncology Group (JGOG) data center and reviewed by the members of the radiotherapy committee. The QA evaluation was classed as per protocol, deviation, and violation. Individual case reviews were performed on 69 of 72 patients entered in the study. In 24 patients (35%), there were no deviations for any QA items. There were also no deviations seen for 5 of the 18 items in 69 patients evaluated. Deviations of 64 QA items were seen in 45 cases, and violations were seen in 4 cases (4 items). The most common deviation concerned appropriate application for the external beam radiotherapy (EBRT) boost to involved nodes or parametrium (32 cases). The 4 violations were identified in the QA items regarding high-dose rate intracavitary brachytherapy. Radiotherapy protocol compliance was favorable except for the EBRT boost indications. The results of this study validate the quality of radiotherapy in JGOG1066, and indicate that the final analysis will provide meaningful results. (author)

    Uterine artery embolization (UAE) is a common treatment for post-partum hemorrhage and uterine fibroids. However, the effects of UAE on subsequent pregnancies have not been established. Here, we present a case of spontaneous uterine rupture after previous UAE. A 31-year-old woman underwent UAE for a cervical ectopic pregnancy. Contrast-enhanced magnetic resonance imaging (MRI) at days 5 and 25 post-UAE suggested a regionally decreased blood supply in the mid-posterior wall of the uterine fundus. During a subsequent pregnancy at age 35 years, she underwent an emergency cesarean delivery due to spontaneous uterine rupture at the mid-posterior wall of the uterus at 32 weeks of gestation. Obstetricians should be attentive to the possibility of spontaneous uterine rupture in pregnant women who have previously undergone UAE. Detection of ischemic uterine muscle on MRI may predict potential for uterine rupture in a subsequent pregnancy. PMID:23945024

A total of 24 women were interviewed, between eighteen and sixty years old, who attended the cancer prevention unit at a basic healthcare clinic in Fortaleza, Ceará State between April and August 2004. This study shows that women generally request these preventive examinations only when symptoms appear. They view this procedure with apprehension and fear, due to the possibility of a positive diagnosis of cervical-uterine cancer; they feel embarrassed at exposing their bodies for examination, particularly by male physicians; and they are poorly informed about their own bodies and even their own sexuality. These findings highlight the need for healthcare practitioners to conduct educational activities for women, in order to enhance professional relationships between healthcare providers and users, helping lower the rate of this type of cancer through more frequent preventive examinations.

M [...] aterial y Método: Estudio observacional, transversal, de cohorte, retrospectivo de mujeres de cualquier edad con diagnóstico de cáncer cervicouterino invasor. La información de las pacientes se tomó de los registros automatizados de las lesiones de cuello uterino de la consulta provincial de Patología de Cuello, del Provincial de Cáncer (Dirección Provincial de Salud), y del de Mortalidad General (Dirección Provincial de Salud) así como de las historias clínicas de la Unidad Oncológica Provincial. Entre las variables estudiadas estuvieron si procedían o no del programa, edad, estadio clínico, tratamiento recibido, incidencia anual y el promedio en la etapa, la mortalidad y la letalidad. Resultados: Se encontró que el 70,6% de casos no se detectó por programa. La tasa de incidencia promedio fue 29.5 por 100000 mujeres de 15 años y más. Todas las pacientes recibieron el tratamiento oncoespecífico según estadio clínico. Las mayores tasas de mortalidad se encontraron en las pacientes en estadio IIIB al diagnóstico. Conclusiones: Se detectan fallas en la Atención Primaria de Salud, por falta de detección. Las tasas de incidencia de esta enfermedad no se han logrado disminuir. Y se siguen diagnosticando casos en estadios avanzados de la enfermedad, lo que acorta la sobrevida de estas pacientes.

Material and Methods: observational, cross-sectional, cohort, retrospective study including women at every age with invasive cervical-uterine cancer. The information concerning the patients was collected from the automated records of cervical uterine at the provincial office for cervix pathology treatment (Provincial Public Health Direction), general death rate (Provincial Public Health Direction) and from the clinical histories of the Provincial Cancer Unit. Among the variables studied were: coming or not from the program, age, clinical stage, treatment followed, and annual incidence, together with the average of mortality and lethality considering the clinical stages. Results: 70,6% of the cases were not detected by the program. The average incidence rate was 29.5 per 10 0000 women from 15 years old or older. All patients underwent to a specific cancer treatment according to the clinical stage. The greatest mortality rates were found in patients presenting IIIB stage at diagnosis. Conclusion: errors were observed in Primary Health Care leading to deficiencies in the early detection of this type cancer. The incidence rates of this disease have not diminished; cases suffering from advanced stages of the disease are still detected, shortening the survival rate of these patients.

  3. Magnetic resonance imaging of cancer of uterine cervix and body. Preliminary study in 9 cases of body cancer and 20 of cervical cancer

    International Nuclear Information System (INIS)

    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

  4. The benefit of small bowel and pelvic bone sparing in excluding common iliac lymph node region from conventional radiation fields in patients with uterine cervical cancer. A dosimetric study

    International Nuclear Information System (INIS)

    The purpose of this study was to compare dose reduction to the small bowel and sacral bone by two-field and four-field techniques when the common iliac lymph node region is excluded from the radiation field in external beam radiotherapy of uterine cervical cancer. Thirteen patients with cervical cancer were entered into the study. Conventional treatment plans based on bony landmarks were made with parallel-opposed two-field technique (C2F) and four-field box technique (C4F). Modified C2F (M2F) and C4F (M4F) plans of excluding the common iliac lymph node region from the conventional radiation fields were created in reference to the bifurcations of pelvic arteries in computed tomography images. For each patient, the dose volume histograms for the small bowel and sacral bone resulting from the C2F, C4F, M2F, and M4F plans were compared. The volumes were obtained at 10 levels of prescribed dose, at increments of 10%, from 5 Gy to 50 Gy. By sparing both small bowel and sacral bone, the M2F and M4F plans were significantly better than the C2F and C4F plans at any dose level (p<0.05), respectively. In addition, the M4F plan was significantly better than the M2F plan in sparing both small bowel at 10-50% of the prescribed dose (p<0.05) and sacral bone at 40-100% of the prescribed dose (p<0.05). The present study suggests that modified treatment planning could be useful for selected patients for reducing small bowel complications and insufficiency fracture after radiotherapy. (author)

    The patient was a 59-year-old woman. Total hysterectomy and irradiation were performed for uterine cervical cancer 25 year previously. Paget's cells resembling signet ring cells were found in the epidermis, and anal cancer was present adjacent to them. The histological diagnosis of the anal cancer was mainly well differentiated adenocarcinoma, but mucinous carcinoma was present containing signet ring cells at sites contiguous with the anal glands, and lymphatic permeation was noted in the dermis. The cancer and the Paget's cells were both positive for PAS and alcian blue staining and were negative for PB/KOH/PAS staining. Furthermore, such findings as atypia of the glandular ducts and endoarteritis were detected in the underlying mucosa. Therefore, it was considered that this patient had anal cancer derived from the anal glands, that the Paget's cells were due to the intraepidermal extension of signet ring cells, and that the cancer may have been related to her previous irradiation. Reports of cancer of the rectum and anus complicated by Paget's lesion in Japan were reviewed and studied with regard to the histogenesis. It was concluded that peri-anal Paget's lesion had a close relationship with anal cancer derived from the anal glands. (author).

Hace un año en el Servicio de Ginecología del Hospital IV Huancayo iniciamos el tratamiento quirúrgico laparoscópico en estos estadios. Objetivos: Revisar los resultados de histerectomía laparoscópica en cáncer microinvasivo de cuello uterino. Diseño: Estudio retrospectivo. Institución: Servicio de Ginecología, Hospital IV Huancayo, EsSalud, Junín, Perú. Pacientes: Doce mujeres sometidas a histerectomía laparoscópica por carcinoma microinvasivo de cérvix. Intervenciones: En seis mujeres con diagnóstico preoperatorio de cáncer de cérvix por conización cervical y estadio clínico Ia1 se les realizó histerectomía laparoscópica, con un tiempo operatorio de 59,16 minutos y tiempo de estancia hospitalaria de 4,1 días. A otras seis mujeres con estadio clínico Ia2-Ib1 se les realizó histerectomía radical más linfadenectomía pélvica laparoscópica, con un tiempo operatorio de 3 horas 58 minutos y tiempo de estancia hospitalaria de 10,1 días. Principales medidas de resultados: Curación clínica. Resultados: Todos los diagnósticos fueron confirmados con la pieza operatoria, y todas las pacientes están teóricamente curadas (márgenes libres, ganglios negativos); una paciente presentó complicaciones, requiriendo estancia prolongada (8,3%). Conclusiones: La histerectomía total laparoscópica y la histerectomía radical más linfadenectomía pélvica laparoscópica pueden ser realizadas de manera más rápida y radical con respecto a la histerectomía convencional por laparotomía. Ambas son intervenciones factibles y seguras, que pueden garantizar la curación en el carcinoma microinvasivo de cuello uterino. Abstract in english Introduction: Cervical cancer is the most common cause of death in Peruvian central highlands.

Objectives: To review outcomes of laparoscopic hysterectomy for microinvasive cervical cancer. Design: Retrospective study. Setting: Gynecology Service, Hospital IV Huancayo, EsSalud, Junin, Peru. Patients: Twelve women subjected to laparoscopic hysterectomy for cervical microinvasive carcinoma. Interventions: Six women with preoperative diagnosis by cervical conization and clinical stage IA1 underwent laparoscopic hysterectomy with 59.16 minutes operative time and 4.1 days hospital stay. Other six women with clinical stage Ia2-Ib1 underwent laparoscopic radical hysterectomy plus pelvic lymphadenectomy with operative time 3 hours and 58 minutes, and hospital stay of 10.1 days. Main outcome measures: Clinical cancer cure. Results: All diagnoses were confirmed by the surgical specimen and all were theoretically cured (negative margins, negative lymph nodes); one patient had complications that required prolonged stay (8.3%). Conclusions: Total laparoscopic hysterectomy and laparoscopic radical hysterectomy plus pelvic lymphadenectomy can be performed faster and more radically compared with conventional laparotomy. Both are feasible and safe interventions that ensure cure in microinvasive cervical carcinoma.

    Curie-therapy conventionally comes before surgery in the treatment of cervical cancer, either alone or after a concomitant chemotherapy. The authors report a study of the impact of a reverse sequence (surgery before curie-therapy) on the exeresis quality and on the evolution of operable tumours. Among women treated between 2004 and 2009, 40 have been identified who had surgery before curie-therapy. Ages, tumour stages, average doses, and treatment procedures are discussed. The notably high rate of vaginal sections could be reduced or avoided by using the conventional protocol (curie-therapy before surgery). Short communication

    MØller, B R; Kristiansen, F V

    1995-01-01

    In a prospective open study the sterility of the uterine cavity was evaluated in 99 women admitted for hysterectomy. The indications for hysterectomy were in most cases persistent irregular vaginal bleeding and fibromyomas of the uterus. Samples for both aerobic and anaerobic bacteria, Chlamydia trachomatis, yeasts and viruses were taken preoperatively from the apex of the vagina and cervical os. Immediately after hysterectomy the uterus was opened under sterile conditions and samples obtained from the isthmus and fundus of the uterine cavity for microbiological examination. Wet smears were taken from the same sites. Nearly a quarter of all the patients harbored one or more microorganisms in the uterus, mostly Gardnerella vaginalis, Enterobacter and Streptococcus agalactiae. We found that in a significant number of cases, the uterine cavity is colonized with potentially pathogenic organisms which may play a causative role in endometritis. The results indicate that inflammation of the uterine cavity should be evaluated by hysteroscopic examination before hysterectomy is undertaken in patients with persistent irregular vaginal bleeding.

  13. Insufficiency Fractures After Pelvic Radiation Therapy for Uterine Cervical Cancer: An Analysis of Subjects in a Prospective Multi-institutional Trial, and Cooperative Study of the Japan Radiation Oncology Group (JAROG) and Japanese Radiation Oncology Study Group (JROSG)

    International Nuclear Information System (INIS)

    Purpose: To investigate pelvic insufficiency fractures (IF) after definitive pelvic radiation therapy for early-stage uterine cervical cancer, by analyzing subjects of a prospective, multi-institutional study. Materials and Methods: Between September 2004 and July 2007, 59 eligible patients were analyzed. The median age was 73 years (range, 37-84 years). The International Federation of Gynecologic Oncology and Obstetrics stages were Ib1 in 35, IIa in 12, and IIb in 12 patients. Patients were treated with the constant method, which consisted of whole-pelvic external-beam radiation therapy of 50 Gy/25 fractions and high-dose-rate intracavitary brachytherapy of 24 Gy/4 fractions without chemotherapy. After radiation therapy the patients were evaluated by both pelvic CT and pelvic MRI at 3, 6, 12, 18, and 24 months. Diagnosis of IF was made when the patients had both CT and MRI findings, neither recurrent tumor lesions nor traumatic histories. The CT findings of IF were defined as fracture lines or sclerotic linear changes in the bones, and MRI findings of IF were defined as signal intensity changes in the bones, both on T1- and T2-weighted images. Results: The median follow-up was 24 months. The 2-year pelvic IF cumulative occurrence rate was 36.9% (21 patients). Using Common Terminology Criteria for Adverse Events version 3.0, grade 1, 2, and 3 IF were seen in 12 (21%), 6 (10%), and 3 patients (5%), respectively. Sixteen patients had multiple fractures, so IF were identified at 44 sites. The pelvic IF were frequently seen at the sacroileal joints (32 sites, 72%). Nine patients complained of pain. All patients' pains were palliated by rest or non-narcotic analgesic drugs. Higher age (>70 years) and low body weight (<50 kg) were thought to be risk factors for pelvic IF (P=.007 and P=.013, Cox hazard test). Conclusions: Cervical cancer patients with higher age and low body weight may be at some risk for the development of pelvic IF after pelvic radiation therapy.

    Purpose: To determine the efficacy of a definitive radiotherapy protocol using high-dose-rate intracavitary brachytherapy (HDR-ICBT) with a low cumulative dose schedule in nonbulky early-stage cervical cancer patients, we conducted a prospective multi-institutional study. Methods and Materials: Eligible patients had squamous cell carcinoma of the intact uterine cervix, Federation of Gynecologic Oncology and Obstetrics (FIGO) stages Ib1, IIa, and IIb, tumor size <40 mm in diameter (assessed by T2-weighted magnetic resonance imaging), and no pelvic/para-aortic lymphadenopathy. The treatment protocol consisted of whole-pelvis external beam radiotherapy (EBRT) of 20 Gy/10 fractions, pelvic EBRT with midline block of 30 Gy/15 fractions, and HDR-ICBT of 24 Gy/4 fractions (at point A). The cumulative biologically effective dose (BED) was 62 Gy{sub 10} ({alpha}/{beta} = 10) at point A. The primary endpoint was the 2-year pelvic disease progression-free (PDPF) rate. All patients received a radiotherapy quality assurance review. Results: Between September 2004 and July 2007, 60 eligible patients were enrolled. Thirty-six patients were assessed with FIGO stage Ib1; 12 patients with stage IIa; and 12 patients with stage IIb. Median tumor diameter was 28 mm (range, 6-39 mm). Median overall treatment time was 43 days. Median follow-up was 49 months (range, 7-72 months). Seven patients developed recurrences: 3 patients had pelvic recurrences (2 central, 1 nodal), and 4 patients had distant metastases. The 2-year PDPF was 96% (95% confidence interval [CI], 92%-100%). The 2-year disease-free and overall survival rates were 90% (95% CI, 82%-98%) and 95% (95% CI, 89%-100%), respectively. The 2-year late complication rates (according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer of Grade {>=}1) were 18% (95% CI, 8%-28%) for large intestine/rectum, 4% (95% CI, 0%-8%) for small intestine, and 0% for bladder. No Grade {>=}3 cases were observed for genitourinary/gastrointestinal late complications. Conclusions: These results suggest that definitive radiotherapy using HDR-ICBT with a low cumulative dose schedule (BED, 62 Gy{sub 10} at point A) can provide excellent local control without severe toxicity in nonbulky (<4-cm) early-stage cervical cancer.

  17. Computed Tomography-Based High-Dose-Rate Intracavitary Brachytherapy for Uterine Cervical Cancer: Preliminary Demonstration of Correlation Between Dose-Volume Parameters and Rectal Mucosal Changes Observed by Flexible Sigmoidoscopy

    International Nuclear Information System (INIS)

    Purpose: To compare the dose-volume histogram (DVH) parameters obtained by three-dimensional gynecologic brachytherapy planning with the rectosigmoid mucosal changes observed by flexible sigmoidoscopy. Methods and Materials: Between January 2004 and July 2005, 71 patients with International Federation of Gynecology and Obstetrics Stage IB-IIIB uterine cervical cancer underwent computed tomography-based high-dose-rate intracavitary brachytherapy. The total dose (external beam radiotherapy [RT] plus intracavitary brachytherapy) to the International Commission of Radiation Units and Measurements rectal point (ICRURP) and DVH parameters for rectosigmoid colon were calculated using the equivalent dose in 2-Gy fractions (?/? = 3 Gy). Sigmoidoscopy was performed every 6 months after RT, with the 6-scale scoring system used to determine mucosal changes. Results: The mean values of the DVH parameters and ICRURP were significantly greater in patients with a score of ?2 than in those with a score RP, 71 Gy?/?3 vs. 66 Gy?/?3, p = 0.02; D0.1cc, 93 Gy?/?3 vs. 85 Gy?/?3, p = 0.04; D1cc, 80 Gy?/?3 vs. 73 Gy?/?3, p = 0.02; D2cc, 75 Gy?/?3 vs. 69 Gy?/?3, p = 0.02). The probability of a score of ?2 showed a significant relationship with the DVH parameters and ICRURP (ICRURP, p = 0.03; D0.1cc, p = 0.05; D1cc, p = 0.02; D2cc, p = 0.02). Conclusion: Our preliminary data have shown that DVH values of the rectosigmoid colon obtained by computed tomography-based three-dimensional brachytherapy planning are reliable and predictive of score ?2 rectosigmoid mucosal changes

    We describe cervical pregnancy concept and its rareness. Its frequency is one in 2,550 to 98,000 intrauterine pregnancies. Predisposing factors are related with endometrial damage due to uterine curettages and previous cesarian section. Clinical picture was nonspecific and diagnosis was based in endovaginal ultrasonography. It can cause massive bleeding and put life in risk. During 2007 we attend 829 intrauterine pregnancies at Hospital San José de Querétaro: 11 tubal, and 3 cervical, this represents an extraordinarily high frequency of cervical pregnancy. Here we report three cases of cervical pregnancies treated with total hysterectomy, two as urgency and one elective. We remark early diagnosis importance to perform conservative treatment and maintain reproductive function. PMID:19149404

  2. Intracavitary combined with CT-guided interstitial brachytherapy for locally advanced uterine cervical cancer. Introduction of the technique and a case presentation

    International Nuclear Information System (INIS)

    We report a new technique of brachytherapy consisting of intracavitary combined with computed tomography (CT)-guided interstitial brachytherapy for locally advanced cervical cancer. A Fletcher-Suit applicator and trocar point needles were used for performing high-dose rate brachytherapy under in-room CT guidance. First, a tandem and ovoids were implanted into the patient's vagina and uterus by conventional brachytherapy method. Based on clinical examination and MRI/CT imaging, operating radiation oncologists decided the positions of insertion in the tumor and the depth of the needles from the upper surface of the ovoid. Insertion of the needle applicator was performed from the vaginal vault inside the ovoid within the tumor under CT guidance. In treatment planning, dwell positions and time adaptations within the tandem and ovoids were performed first for optimization based on the Manchester system, and then stepwise addition of dwell positions within the needle was continued. Finally, dwell positions and dwell weights were manually modified until dose-volume constraints were optimally matched. In our pilot case, the dose of D90 to high-risk clinical target volume was improved from 3.5 Gy to 6.1 Gy by using our hybrid method on the dose-volume histogram. D1cc of the rectum, bladder and sigmoid colon by our hybrid method was 4.8 Gy, 6.4 Gy and 3.5 Gy, respectively. This method consists of advanced image-guided brachytherapy that can be performed safely and accurately. This approach has the potential of increasing target coverage, treated volume, and total dose without increasing the dose to organs at risk. (author)

    International Nuclear Information System (INIS)

    Objective: Study the value of clinical application of Baiji and absorbable Gelatin in embolizing uterine myoma together with its effect, side effect and complication. Methods: 21 women with uterine myoma undergoing selective uterine arterial embolization by Seldinger's technique were studied. After retrograde trans-femoral introduction of a 5 french catheter, the uterine arteries were successively catheterized. Baiji and absorbable Gelatin sponge particles were injected through free flow until devasculariztion. Results: Uterine myomas blood supply came from bilateral uterine arteries demonstrated by angiography. All the supplying artery images disappeared after the embolization. 3-6 months follow-up study showed: a marked reduction in the size of myomata by 38%-90%. Clinical symptoms were improved. There was one failure cas and then underwent uterotomy due to infection. Conclusions: The short-term effect of using Baiji and absorbable Gelatin for embolizing uterine myoma is clinically significant, while long-term effects is still waiting for research

    Nonspecific uterine infections reduce the reproductive efficiency of cows and the profit potential of dairy farms. Fortunately, most cows do not develop severe uterine infections. The term uterine infection indicates that the uterus is contaminated with pathogenic organisms. Actinomyces pyogenes, either alone or with other bacteria, is often associated with uterine infections. When A. pyogenes was isolated from uterine fluids after d 21 postpartum, cows developed severe endometritis and were infertile at first service. However, the exact causes of uterine infections are unknown but are associated with several factors. Cows with dystocia, retained placenta, twins or still-births, and various metabolic disorders are more likely to develop metritis than are other cows. Aberrant immune function before and after calving seems to predispose cows to severe uterine infections. Few cows die from uterine infections, but cows with uterine infections are more likely to be culled for poor reproductive performance. Also, uterine infections can reduce milk production, and some treatments contaminate milk. Because they are nonspecific, uterine infections are difficult to prevent; attention to sanitation and periparturient hygiene, especially during assisted calving, may be the best defense. Evidence that aberrant immuno function predisposes cows to uterine infections indicates that methods for regulating immune function in periparturient cows have the potential for preventing or treating uterine infections.

    The aim of this pictorial review was to illustrate the normal cervix appearance on T2-weighted images, and give a review of common or less common disorders of the uterine cervix that appear as high signal intensity lesions on T2-weighted sequences. Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions. (orig.)

Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions. (orig.)

    A modified afterloading cervical applicator and intracavitary endocurietherapy application technique eliminates several problems associated with the Henschke cervical applicator, and conventional preloading technique. 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. The use of hygroscopic laminaria tent for gradual cervical dilatation in place of manual cervical dilatation, and the use of inflatable Foley balloon threaded onto the tandem instead of vaginal packing, to separate the /sup 137/Cesium sources away from the rectum and bladder, eliminate the need of general anesthesia for the majority of patients undergoing intracavitary endocurietherapy.

    Full Text Available Abstract Introduction Conservative treatment of a heterotopic cervical pregnancy was performed with a modification of the fixation of a Foley catheter at the level of the external cervical os, followed by the ligature of the descending cervical branches of the uterine arteries and systemic methotrexate application. Case presentation A 34-year-old Caucasian woman was diagnosed with double gestation after 6 weeks of in vitro fertilization treatment. A gynecological examination and color Doppler ultrasound scan revealed intra-uterine and cervical gestational sacs both containing live fetuses. A Foley catheter balloon was inserted into the cervical canal, inflated and fixed by a cerclage suture at the level of the external cervical os, followed by ligation of the descending cervical branches of the uterine arteries. Systemic methotrexate was applied. Three days after removal of the Foley catheter, an evacuation of the intra-uterine gestational sac was performed. Hemorrhage from the implantation site was controlled immediately and a pregnancy termination was successfully performed. The procedure was uneventful and our patient was discharged with a preserved uterus. Conclusions Conservative treatment of cervical pregnancy using a Foley catheter balloon is more efficacious if the Foley catheter balloon is attached in the correct position with a cerclage suture at the level of the external os, followed by ligation of the descending cervical branches of the uterine arteries, thereby exerting maximal pressure on the bleeding vessels.

  20. Uterine artery embolization to treat uterine fibroids

    International Nuclear Information System (INIS)

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

    Malignant mixed mullerian tumors (MMMTs) are a rare uterine tumor and contribute to approximately 1-3% of all corpus malignant tumors. MMMTs are usually in the uterine corpus, but can also arise from the uterine cervix, vagina, ovaries and fallofian tubes. MMMTs of the uterine cervix are extremely rare. MMMTs are highly malignant and tend to maintain a rapid growth and exhibit a high rate of recurrence. Therefore, the prognosis of patients diagnosed with these types of tumors is extremely poor. We report a rare case of a malignant mixed mullerian tumor arising from the uterine cervix and introduce CT and MRI findings. CT and magnetic resonance findings of the uterine cervical MMMT in our case show highly aggressive features, such as parametrial involvement, pelvic and paraaortic lymphadenopathy, and distant metastasis and high enhancement.

    In this randomized prospective study, we determined the conception rate following intra-uterine insemination with washed and prepared sperm, or with the first portion of a split ejaculate, in couples with longstanding male (n = 27, 70 treatment cycles) or cervical infertility (n = 14, 29 treatment cycles). Folliculogenesis and ovulation were induced by human menopausal gonadotropin and human chorionic gonadotropin. Significantly more couples conceived in the male infertility group following intra-uterine insemination with washed sperm, than after intra-uterine insemination with split ejaculate (9 vs. 2; P less than 0.05), while no difference in pregnancy rate (2 vs. 2) was found by the two intra-uterine insemination methods in the cervical infertility group.

    Full Text Available PURPOSE: To investigate E-cadherin immunoexpression during cervical carcinogenesis. METHODS: We assessed the immunohistochemical expression of E-cadherin in squamous intraepithelial lesions (SIL - 52 cases), squamous cell carcinoma (SCC) of the uterine cervix (23 cases) and also in eight cases [...] of cervicitis. RESULTS: The results show very different E-cadherin membrane expression levels when cervicitis (88%), SILs (73%) and SCC (17%) were compared. In SILs, higher E-cadherin loss was seen in less differentiated cells in the basal third of the epithelium. This study suggests that the absence of E-cadherin expression in the membrane is a molecular event that is observed more often in SCC of the uterine cervix than in SILs or cervicitis. CONCLUSIONS: E-cadherin is an essential molecule during the process of cervical carcinogenesis and in this context exhibits a different expression pattern according to the epithelial thickness layer.

    International Nuclear Information System (INIS)

    Uterine radioactivity uptake has previously been reported for a variety of radionuclide agents in the presence of uterine pathological disorders, such as leiomyomata as well as uterine and cervical neoplasma and infections. Activity within the normal uterus has also been reported in Meckel's scans using sup(99m)Tc-pertechnetate, but this has not been reported for other radionuclide agents. We report a case exhibiting radioactivity uptake within a normal uterus on a sup(99m)Tc-glucoheptonate scan of a renal transplant. Awareness of the possibility of radioactivity uptake in a normal uterus is important in order to avoid potential confusion with abnormal pelvic masses or fluid occumulations. (orig.)

    Full Text Available Background : Cancer of cervix is the most common form of cancer in females of developing countries. Cervical cancer is the best example of common human malignancy with a proven infectious etiology. The data linking human papilloma virus (HPV infection with the epidemiology and pathogenesis of cervical neoplasia is convincing. There are various methods for detection of HPV like immunohistochemistry, polymerase chain reaction, liquid phase hybridization (hybrid capture test, in situ hybridization etc. Materials and Methods: We studied the profile of precancerous and cancerous lesions of uterine cervix and correlated human papilloma virus (HPV presence with precancerous and cancerous lesions of uterine cervix by immunohistochemistry. Total 50 cases were first studied, analyzed, and classified histologically and then immunohistochemistry was done. Results : Majority of the cases 36/50 (72% under study are squamous cell carcinomas, which is the most common carcinoma found in the uterine cervix. HPV positivity for all cases of cervical carcinoma was found to be 34.7% (16/46 cases, for carcinoma in situ, it was 50% (2/4 cases. It can be thus hypothesized that with decreasing differentiation, there is loss of expression of HPV in the cervical epithelial cells. Conclusion: To conclude, though this study confirms the correlation of HPV presence with precancerous and cancerous lesions of uterine cervix, it also suggests that there must be other co-factors involved in cervical carcinogenesis as well.

    Full Text Available Uterine mesenchymal tumors are a heterogeneous group of neoplasms that can frequently be diagnostically challenging. Differentiation between the benign and malignant counterparts of mesenchymal tumors is significant due to differences in clinical outcome, and the role of the surgical pathologist in making this distinction (especially in the difficult cases cannot be underestimated. Although immunohistochemical stains are supportive toward establishing a final diagnosis, the morphologic features trump all the other ancillary techniques for this group of neoplasms. This review therefore emphasizes the key morphologic features required to diagnose and distinguish uterine mesenchymal tumors from their mimics, with a brief description of the relevant immunohistochemical features.

    The authors report the dosimetric comparison of two techniques used for the treatment of cervical cancers: the intensity-modulated conformational radiotherapy (IMRT) with static beams and modulated arc-therapy with RapidArc. The treatment plans of 15 patients have been compared. The clinical target volume (CTV) comprises the gross target volume, the cervix, the upper third of the vagina, and ganglionary areas. The previsional target volume comprises the clinical target volume and a one centimetre margin. Organs at risk are rectum, bladder, intestine and bone marrow. Arc-therapy seems to provide a better sparing of intestine that IMRT, while maintaining a good coverage of the previsional target volume and decreasing treatment duration. Short communication

    To analyze gray-scale US, color and duplex Doppler US, and angiographic findings in patients with acquired uterine arteriovenous malformations (AVMs), and to evaluate the usefulness of these modalities in the diagnosis of this disease and the effect of transcatheter arterial embolization in its treatment. During a recent seven-year period, we diagnosed 21 cases of acquired uterine AVM. Nineteen of these patients had a history of causative D and C (between one and seven D and C procedures per patient), one had a history of causative cesarean section, and one had cervical conization. All patients underwent transabdominal and endovaginal gray-scale, color Doppler, and duplex Doppler US and angiography, with therapeutic embolization of bilateral uterine arteries. The majority underwent follow-up Doppler US after embolization. The gray-scale US morphology of uterine AVMs included subtle myometrial inhomogeneity and multiple distinct, small anechoic spaces in the thickened myometrium or endometrium. Color Doppler US showed a tangle of tortuous vessels with multidirectional, high-velocity arterial flow, which was focally or asymmetrically distributed. Duplex Doppler US depicted a waveform of fast arterial flow with low resistance, while angiography demonstrated a complex tangle of vessels supplied by enlarged uterine arteries, in association with early venous drainage during the arterial phase, and staiss of contrast medium within abnormal vasculature. Where AVMs were combined with a pseudoaneurysm, this finding was observed. Transcatheter arterial embolization provided a complete cure, without recurrence. Color and duplex Doppler US in an appropriate modality for the detection and diagnosis of uterine AVMs and for follow-up after embolization. Transcatheter arterial embolization is a safe and effective method of treating this disease.

    Embolization has become a first-line treatment for symptomatic uterine fibroid tumors. Selective catheterization and embolization of both uterine arteries, which are the predominant source of blood flow to fibroid tumors in most cases, is the cornerstone of treatment. Although embolization for treatment of uterine fibroid tumors is widely accepted, great familiarity with the normal and variant pelvic arterial anatomy is needed to ensure the safety and success of the procedure. The uterine artery classically arises as a first or second branch of the anterior division of the internal iliac artery and is usually dilated in the presence of a uterine fibroid tumor. Angiography is used for comprehensive pretreatment assessment of the pelvic arterial anatomy; for noninvasive evaluation, Doppler ultrasonography, contrast material-enhanced magnetic resonance (MR) imaging, and MR angiography also may be used. After the uterine artery is identified, selective catheterization should be performed distal to its cervicovaginal branch. For targeted embolization of the perifibroid arterial plexus, injection of particles with diameters larger than 500 mum is generally recommended. Excessive embolization may injure normal myometrium, ovaries, or fallopian tubes and lead to uterine necrosis or infection or to ovarian failure. Incomplete treatment or additional blood supply to the tumor (eg, via an ovarian artery) may result in clinical failure. The common postembolization angiographic end point is occlusion of the uterine arterial branches to the fibroid tumor while antegrade flow is maintained in the main uterine artery. PMID:16227501

Material y método: se realizó un estudio retrospectivo, longitudinal para conocer la incidencia anual de lesiones premalignas y malignas del cuello uterino en mujeres pinareñas menores de 25 años. La muestra estuvo conformada por el resultado de las biopsias realizadas a estas jóvenes en ese período. Resultados: la incidencia anual por 10000 mujeres 10-24 años fue de 8.8 para las NIC I; 3,1 en NIC II; 1,6 para las NIC III + CIS, 0.07 para el microinvasor, 0.03 para el invasor Ib y 0.02 para el invasor estadio II. No se detectaron ni estadios superiores de la variedad epidermoide y adenocarcinomas endocervicales. La incidencia anual para cada una de las lesiones mostró una tendencia al incremento sobre todo para las NIC I. De 1198 biopsias realizadas en este grupo etario solamente se detectaron 7 carcinomas epidermoides invasores cervicales en 10 años, 0.7 anuales, con tasa de 5.8 x cada 1000 mujeres de 10-24 años. Conclusiones: la incidencia detectada de lesiones malignas en este grupo no justificaría comenzar la realización del pesquisaje citológico antes de los 25 años, ya que el costo sería alto y el beneficio mínimo. Abstract in english Introduction: malignant and pre-malignant lesions have been localized in women less than 25 years, but the exact enormity of the problem in Pinar del Río is not known. Objective: to evaluate the tendency and incidence of malignant and pre-malign cervical lesions in Pinar women less than 25 years old [...] according to demographic characteristics, in the period 2003-2012. Material and method: a retrospective, cross-sectional study was carried out, in order to know the annual incidence of malign and pre-malign cervical lesions in Pinar women younger than 25 years. The sample comprised the results of biopsies made of those women in that period. Results: the annual incidence in 10,000 women from 10-24 years old was 8.8 for CIN1, 3.1 for CIN2, 1.6 for CIN3 + CIS (carcinoma in situ), 0.07 for de micro-invasive, 0.03 for the invasive Ib, and 0.02 for the invasive stage II. Stages over neither epidermoidal nor endocervical adenocarcinomas were detected. The annual incidence in each lesion proved increasing particularly for NIC1 cases. Out of 1,198 biopsies made on this age group, only 10 invasive epidermoidal carcinomas were detected in ten years, 0.7 annually, with a proportion of 5.8 per 1,000 women between 10-24 years of age. Conclusions: The tendency of malignant lesions detected in this group would not justify starting the cytological screening before the 25 years of age, since the cost would high and the benefit would be minimal.

  15. Staging of carcinoma of the uterine cervix and endometrium

    Carcinoma of the uterine cervix and endometrium are common gynecologic malignancies. Both carcinomas are staged and managed by means of the International Federation of Gynecology and Obstetrics (FIGO) staging system. In uterine cervical cancer, the FIGO staging system is determined preoperatively by limited conventional procedures. Although this system is effective for early stage disease, it has inherent inaccuracies in advanced stage diseases and does not address nodal involvement. CT and MR imaging are widely used as comprehensive imaging modalities to evaluate tumor size and extent, and nodal involvement. MR imaging is an excellent modality for depicting invasive cervical carcinoma and can provide objective measurement of tumor volume, and provides high negative predictive value for parametrial invasion and stage IVA disease. In contrast, endometrial cancer is surgically staged. Beside recognition of the important prognostic factors, including histologic subtype and grade, accurate assessment of the tumor extent on preoperative MR imaging is expected to greatly optimize surgical procedure and therapeutic strategy. Contrast-enhanced MR imaging can offer ''one stop'' examination for evaluating the depth of myometrial invasion cervical invasion and nodal metastases. Evaluation of myometrial invasion on MR imaging may be an alternative to gross inspection of the uterus during the surgery. (orig.)

  16. Clinical assessment of uterine endometrial cancer by magnetic resonance imaging

    International Nuclear Information System (INIS)

    A retrospective review of magnetic resonance (MR) images of 33 patients with surgically proved uterine endometrial cancer was done to define the essential sequence of MR imaging for the purpose of shortening of the scan time. Only T2 weighted sagittal image was studied for cancer staging. The relation between surgical staging and the ratio of tumor width to uterine width in the sagittal plane as well as direct image analysis was evaluated. The cervical involvement was diagnosed by continuity of tumor intensity into cervical canal, adnexal invasion by swelling of adnexa, myometrial invasion by blurring of tumor-myometrial interface. Accuracy of direct MR imaging analysis as for cervical involvement, adnexal invasion, and myometrial invasion were 83.3%, 77.8%, 73.3% respectively. The tumor volume ratio showed a statistically significant difference (p<0.05) between cases with superficial myometrial invasion and with deep invasion, while there was no difference between cases without myometrial invasion and those with superficial invasion. Thus we suggest that when tumor volume ratio was over 75% one must consider the possibility of deep myometrial invasion even if the tumor-myometrial interface was smooth. (author)

    Prolactin receptor (PRLR) overexpression could play a role in tumorigenesis. The aim of this study was to determine prolactin (PRL) and PRLR expression in biopsies from patients with precursor lesions and uterine cervical cancer. PRLR expression was analyzed in 63 paraffin-embedded biopsies of uterine cervical tissue. In total, eleven low-grade squamous intraepithelial lesions (LSIL), 23 high-grade squamous intraepithelial lesions (HSIL), 21 uterine cervical cancers (UCC) and 8 normal epithelium (NE) were examined using immunoperoxidase staining and Western blot analysis. Additionally, PRL expression was identified in human cervical cancer serum and tissues. The PRLR expression was found to be significantly increased in cervical cancer in comparison with normal tissue and precursor lesions (P < 0.0003). The presence of the long isoform of the PRLR was observed only in cervical cancer tissues. Serum PRL levels were normal in all samples and local prolactin expression was similar in precursor lesions and cervical cancer by Western blot analysis. Our data suggest a possible role for PRLR in the progression of cervical cancer. PMID:24990775

Approximately 80% of ICC cases are diagnosed in under-developed countries. Vaccine development relies on knowledge of HPV genotypes characteristic of LSIL, HSIL and cancer; however, these genotypes remain poorly characterized in many African countries. To contribute to the characterization of HPV genotypes in Northeastern Tanzania, we re...

    Full Text Available El cáncer cervicouterino es el tumor maligno más frecuente entre las mujeres de la India. En los países en desarrollo no es posible emprender programas de cribado citológico de ámbito nacional debido a la escasez de personal adiestrado y a la falta de la infraestructura necesaria. La simple inspecci [...] ón visual del cuello uterino detecta los cánceres tempranos con una menor sensibilidad y especificidad que los estudios citológicos. En nuestros estudios anteriores hallamos una tasa de detección relativamente baja de las lesiones cervicouterinas precancerosas. A raíz de ello desarrollamos el Magnivisualizador, un dispositivo de iluminación y aumento cuyo precio es de Rs 1500 (US$ 36). Pretendíamos así mejorar la sensibilidad de la inspección visual simple en la detección de lesiones precancerosas o indicativas de cáncer temprano.De fácil manejo, este instrumento portátil funciona con una pila recargable de 12 V. Consiste en una cámara de luz con un reflector en un lado y un condensador en el otro, equipada con una bombilla halógena de 12 V y 50 W. La cámara tiene en la parte superior, en el extremo del condensador, un cristal de aumento de 2,5 dioptrías y 100 mm de diámetro. Los resultados de la inspección visual simple realizada mediante el Magnivisualizador fueron comparados con los de la colposcopia y/o los informes histológicos en una muestra de 402 mujeres. En total se diagnosticaron histológicamente 73 displasias leves, 76 displasias avanzadas y 59 carcinomas in situ o cánceres invasivos en sus primeras fases. En el caso de las displasias leves, la sensibilidad del análisis citológico fue del 75,3%, y la del Magnivisualizador, del 57,5%. En lo que atañe a las displasias graves y los carcinomas in situ o los cánceres invasivos tempranos, en cambio, la sensibilidad fue del 94,9% con los dos métodos. La tasa de falsos positivos fue del 1,0% en los estudios citológicos, frente al 5,7% con el Magnivisualizador. La especificidad del cribado alcanzó el 94,3% con este último, y el 99% en el análisis citológico.El Magnivisualizador aumentó considerablemente la sensibilidad conseguida mediante la inspección visual simple, no sólo en la detección de carcinomas in situ o de cánceres invasivos tempranos, sino también en el caso de las lesiones precancerosas. Su sensibilidad en la detección de las displasias avanzadas y las lesiones más graves precitadas fue comparable a la del análisis citológico, y disminuyó la tasa de falsos positivos. Además, el costo del examen con Magnivisualizador fue de US$ 0,55, mientras que el del análisis citológico fue de US$ 1,10. La sencilla inspección visual que permite el dispositivo puede realizarse incluso en un centro de atención primaria, sin más requisito que una mesa de exploración Abstract in english We report on an illuminated, low-cost (Rs 1500 (US$ 36)) magnifying device (Magnivisualizer) for detecting precancerous lesions of the uterine cervix. A total of 403 women attending a maternal and child health care clinic who had abnormal vaginal discharge and related symptoms were referred for deta [...] iled pelvic examination and visual inspection by means of the device after the application of 5% (v/v) acetic acid. Pap smears were obtained at the same time. The results were compared with those obtained using colposcopy and/or histology. The Magnivisualizer improved the detection rate of early cancerous lesions from 60%, for unaided visual inspection, to 95%. It also permitted detection of 58% of cases of low-grade dysplasia and 83% of cases of high-grade dysplasia; none of these cases were detectable by unaided visual inspection. For low-grade dysplasia the sensitivity of detection by means of the Magnivisualizer was 57.5%, in contrast with 75.3% for cytological examination. However, the two methodologies had similar sensitivities for higher grades of lesions. The specificity of screening with the Magnivisualizer was 94.3%, while that of cytology was 99%.

    Relapses of lymphoblastic leukaemia traditionally involve the central nervous system and testes in boys. Involvement of the female pelvic organs is frequently found at autopsy; however, involvement of the cervical uterus is rare and even less commonly symptomatic. A 13-cm uterine mass was discovered in a 15-year-old adolescent with a history of lymphoblastic leukaemia during childhood. Pelvic MRI was the best tool to assess the size, characteristics and invasive nature of this lesion of the uterine cervix. To our knowledge, this is a unique case in that we describe the MRI appearance of a relapsing lymphoblastic leukaemic mass both before and after treatment. (orig.)

    The authors compared the usefulness of MR imaging and CT in staging uterine tumors. Forty women with known cervical carcinoma, endometrial cancer, or leiomyosarcoma underwent CT and MR imaging within 1 week prior to surgery. MR imaging was better than CT for localizing tumors to the endometrium of myometrium and in the evaluation of lymph node involvement and extension to the cervix and parametria. MR imaging, with its superior ability to demonstrate pelvic anatomy and its lack of ionizing radiation and risk from iodinated contrast media, has an important place in the staging of uterine tumors

RESULTADOS: A revisão mostrou que: 1) existe provavelmente associação de ectopia com infecção cervical por Chlamydia trachomatis, pelo vírus HPV e maior risco de soroconversão para HIV; 2) existe provavelmente associação entre ectopia e neoplasia intra-epitelial cervical; 3) existe associação com mucorréia e nictúria; 4) não existem evidências sobre associação entre ectopia e câncer de colo do útero nem sobre proteção contra este câncer proporcionada pelo tratamento da ectopia. CONCLUSÕES: 1) Não foram encontrados na literatura dados que justifiquem o tratamento rotineiro da ectopia; 2) O tratamento pode ser utilizado para tratar sintomas associados à ectopia, porém mais sintomas são atribuídos à ectopia do que se pôde confirmar em um estudo controlado; 3) Seriam necessários novos estudos para testar a hipótese de proteção contra o câncer de colo proporcionada pelo tratamento. Abstract in english CONTEXT AND PURPOSE: Uterine cervical ectopy (cervical erosion) is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. The purpose of this study was to review the medical literature for evidence regarding benefits from treating cervica [...] l ectopy. METHODS: The following databases were reviewed: Medical Literature Analysis and Retrieval System Online (Medline), Excerpta Medica Database (Embase), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) and Cochrane Library databases. In addition, six medical textbooks were consulted. RESULTS: The review showed that: 1) there is probably an association between ectopy and higher risk of Chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4) there is probably an association between ectopy and cervical intraepithelial neoplasia; 5) there is an association between ectopy and mucous discharge and nocturia; and 6) there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. CONCLUSIONS: 1) No data were found in the medical literature to support routine treatment for ectopy; 2) Treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3) Further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

    Positron Emission Tomography (PET) or integrated PET/Computed Tomography (PET/CT) with 18F-Fluoro-Deoxy-Glucose (18F-FDG) is a functional imaging modality, useful in the characterization of undetermined morphological findings, and in the staging/re-staging of a large number of malignancies. Although its use in uterine malignancies has been poorly investigated, in recent years the employment of this technique has constantly increased. In this review, we evaluate the role of PET (/CT) with 18FF...

    Function of the adrenosympathetic system has been assessed in 103 patients with uterine myoma. Levels of biogenic amines (adrenaline, noradrenaline, histamin) were determined in uterine tissues using spectrofluorometry. It was found out that storage of vasoactive mediators in the uterine tissue represents a mechanism of uterine bleedings in patients with uterine myoma. Another determinant is stress experienced by patients with menometrorrhagia. PMID:2339756

    Adenocarcinoma of the endometrium (also known as endometrial cancer or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. An estimated 49,560 new uterine cancer cases will occur in 2013, with 8190 deaths resulting from the disease. Uterine sarcomas (stromal/mesenchymal tumors) are uncommon malignancies, accounting for approximately 3% of all uterine cancers. The NCCN Guidelines for Uterine Neoplasms describe malignant epithelial carcinomas and uterine sarcomas; each of these major categories contains specific histologic groups that require different management. This excerpt of these guidelines focuses on early-stage disease. PMID:24586086

    Full Text Available Abstract Background Stereotactic body radiation therapy (SBRT administered via a helical tomotherapy (HT system is an effective modality for treating lung cancer and metastatic liver tumors. Whether SBRT delivered via HT is a feasible alternative to brachytherapy in treatment of locally advanced cervical cancer in patients with unusual anatomic configurations of the uterus has never been studied. Case Presentation A 46-year-old woman presented with an 8-month history of abnormal vaginal bleeding. Biopsy revealed squamous cell carcinoma of the cervix. Magnetic resonance imaging (MRI showed a cervical tumor with direct invasion of the right parametrium, bilateral hydronephrosis, and multiple uterine myomas. International Federation of Gynecology and Obstetrics (FIGO stage IIIB cervical cancer was diagnosed. Concurrent chemoradiation therapy (CCRT followed by SBRT delivered via HT was administered instead of brachytherapy because of the presence of multiple uterine myomas with bleeding tendency. Total abdominal hysterectomy was performed after 6 weeks of treatment because of the presence of multiple uterine myomas. Neither pelvic MRI nor results of histopathologic examination at X-month follow-up showed evidence of tumor recurrence. Only grade 1 nausea and vomiting during treatment were noted. Lower gastrointestinal bleeding was noted at 14-month follow-up. No fistula formation and no evidence of haematological, gastrointestinal or genitourinary toxicities were noted on the most recent follow-up. Conclusions CCRT followed by SBRT appears to be an effective and safe modality for treatment of cervical cancer. Larger-scale studies are warranted.

    These NCCN Clinical Practice Guidelines in Oncology for Cervical Cancer focus on early-stage disease, because it occurs more frequently in the United States. After careful clinical evaluation and staging, the primary treatment of early-stage cervical cancer is either surgery or radiotherapy. These guidelines include fertility-sparing and non-fertility-sparing treatment for those with early-stage disease, which is disease confined to the uterus. A new fertility-sparing algorithm was added for select patients with stage IA and IB1 disease.. PMID:23486458

    To determine the efficacy and clinical outcome of uterine arterial embolization as a new approach to the management of uterine leiomyomas. Uterine arterial embolization was performed in 21 patients aged 26-62(mean, 42) years. Twenty of these had menorrhagia, dysmenorrhea, and mass-related symptoms (low abdominal discomfort, backache, urinary frequency, etc.) and one was diagnosed incidentally. Bilateral uterine arteries were selected individually and polyvinyl alcohol and/or gelfoam was used as an embolic material. Nineteen patients were followed up after embolization. Seventeen (89.5 %)reported satisfactory improvement of symptoms and follow-up sonography three months later showed a 58.5 % reduction in mean myoma volume. In 17 patients (89.5 %), the menstrual cycle returned to normal. All patients experienced pain after the procedure and other complications were vaginal bleeding (26.3 %) and fever (23.8 %). Uterine arterial embolization represents a new approach to the management of uterine leiomyoma-related symptoms. Further investigations and long-term follow-up are, however, enquired.

    Twenty-five cases of dysplasia of the uterine cervix were studied for the presence of human papillomavirus (HPV) by means of immunohistochemical and electron microscopic techniques. Serial sections of the same histological specimen were examined in each case. HPV was detected in 14 cases by both immunohistochemistry and electron microscopy, while 10 cases were negative with both methods. In only one case, there was a discrepancy in the results derived from these two methods. It was concluded that the relation between HPV infection and cervical dysplasia was confirmed and that immunohistochemical and electron microscopic methods led almost to the same result in detecting HPV in cervical dysplasia.

    Full Text Available Background: Cervical cancer is the second most common cancer in women worldwide. Recent studies show that human papillomavirus (HPV DNA is present in all cervical carcinomas and in some cervicitis cases, with some geographical variation in viral subtypes. Therefore determination of the presence of HPV in the general population of each region can help reveal the role of these viruses in tumors. Objectives: This study aimed to estimate the frequency of infection with HPV in cervicitis, cervical adenocarcinoma, intraepithelial neoplasia and squamus cell carcinoma samples from the Isfahan Province, Iran. Patients and Methods: One hundred and twenty two formalin fixed paraffin embedded tissue samples of crevicitis cases and different cervix tumors including cervical intraepithelial neoplasia (CIN (I, II, III, squamus cell carcinoma (SCC and adenocarcinoma were collected from histopathological files of Al-Zahra Hospital in Isfahan. Data about histopathological changes were collected by reexamination of the hematoxylin and eosin stained sections. DNA was extracted and subjected to Nested PCR using consensus primers, MY09/MY11 and GP5+/GP6+, designed for amplification of a conserved region of the genome coding for L1 protein. Results: In total 74.5% of the tested samples were positive for HPV. Amongst the tested tumors 8 out of 20 (40% of CIN (I, II, III, 5 out of 21 (23.8% of adenocarcinoma cases and 78 out of 79 chronic cervicitis cases were positive for HPV. Conclusions: The rate of different carcinomas and also the rate of HPV infection in each case were lower than other reports from different countries. This could be correlated with the social behavior of women in the area, where they mostly have only one partner throughout their life, and also the rate of smoking behavior of women in the studied population. On the other hand the rate of HPV infection in chronic cervicitis cases was much higher than cases reported by previous studies. This necessitates more attention to the role of human papillomaviruses in the their induction in the studied area. Keywords: Polymerase Chain Reaction; Uterine Cervical Neoplasms; Uterine Cervicitis

  2. Excessive uterine bleeding.

    2012-04-01

    Menstrual bleeding that falls outside the range of normal in adolescents is often a cause of great concern for both girls and their families. Often, much of this anxiety can be alleviated with proper anticipatory guidance about menarche and early menstrual bleeding patterns. Eliciting a menstrual history from an adolescent girl is challenging, and the use of concrete methods to chart their patterns and flow, such as menstrual calendars and pictorial bleeding assessment calendar (PBAC) tools, may be helpful. The importance of obtaining a confidential history from the adolescent girl cannot be overestimated. A confidential sexual history is essential so that pregnancy and infectious causes of bleeding are addressed. Not all menstrual bleeding in young girls is attributable to immaturity of the HPO axis. Anovulation and DUB from other clinically relevant conditions in adolescent girls must also be considered. Chief among these is PCOS, which should always be ruled out when a girl presents with excessive bleeding associated with clinical signs of hyperandrogenism, obesity, or insulin resistance. Attention must also be paid to signs or a family history of a bleeding disorder, as vWD is commonly associated with excessive uterine bleeding. Importantly, the laboratory testing for both PCOS and vWD is affected by therapies for the excessive bleeding, and it should be performed before hormonal interventions or blood products are administered or during the placebo phase if treatment has begun. Management goals for excessive uterine bleeding include stabilizing the endometrium and stopping further blood loss, as well as preventing future uncontrolled blood loss. Hormonal stabilization of the endometrium is often helpful regardless of the cause of bleeding and especially in those with hormonally mediated anovulation. New antifibrinolytics, such as tranexamic acid, may also be helpful in the emergent setting and in adolescents with bleeding disorders. PMID:22764555

    Objective: The purpose of this study was to evaluate the enhancement characteristics of the normal uterine body and cervix using dynamic contrast-enhanced helical CT. Methods: Thirty-eight women scheduled for pelvic CT for non-gynecologic malignancies underwent dynamic contrast-enhanced helical CT of the pelvis. Data acquisition was during the arterial phase (30-45 s after the start of injection), the parenchymal phase (90-120 s after the start of injection), and delayed phase (3-9 min after the start of injection). The images were evaluated by four radiologists for the pattern of myometrial and cervical enhancement. Correlation was made with the age and menstrual status of the patients. Results: In the uterine body, three types of enhancement were observed. Type 1 enhancement, seen in 16 patients (42%), was characterized by the visualization of a subendometrial zone of enhancement, 30-120 s after the start of injection. Eight of these patients also showed an enhancing zone in the outer myometrium. Both zones were transitory, and in all cases, the uterus became homogeneous in the delayed phase. This pattern was seen predominantly in premenopausal women with a mean age of 34 years. Type 2 enhancement, seen in 17 cases (45%), was defined by the absence of subendometrial enhancement in the early phase. Enhancement was either diffuse from the outset or originated in the outer myometrium. This pattern was seen nearly equally in premenopausal and postmenopausal women with a mean age of 40 years. Type 3 enhancement was seen in five postmenopausal patients (13%) with a mean age of 53 years and was characterized by faint diffuse enhancement. In the cervix, a zonal pattern of enhancement defining inner and outer stroma was seen in 23 patients (61%). Fifteen patients were premenopausal and eight were postmenopausal. Conclusion: In this study, we have shown a transitory zonal distribution of the contrast in the myometrium and cervix using dynamic contrast-enhanced helical CT. The demonstration of these patterns is not constant and depends on individual variables. Of these, the menopausal status and/or age of the patient appear to be most important. While CT is not the primary imaging modality to evaluate the uterus, knowledge of these normal findings might help when confronted with unusual uterine enhancement during routine studies obtained with spiral CT.

    Presentation of uterine prolapse is a rare event in a pregnant woman, which can be pre-existent or else manifest in the course of pregnancy. Complications resulting from prolapse of the uterus in pregnancy vary from minor cervical infection to spontaneous abortion, and include preterm labor and maternal and fetal mortality as well as acute urinary retention and urinary tract infection. Moreover, affected women may be at particular risk of dystocia during labor that could necessitate emergency intervention for delivery. Recommendations regarding the management of this infrequent but potentially harmful condition are scarce and outdated. This review will examine the causative factors of uterine prolapse and the antepartum, intrapartum and puerperal complications that may arise from this condition as well as therapeutic options available to the obstetrician. While early recognition and appropriate prenatal management of uterine prolapse during pregnancy is imperative, implementation of conservative treatment modalities throughout pregnancy, these applied in accordance with the severity of the uterus prolapse and the patient's preference, may be sufficient to achieve uneventful pregnancy and normal, spontaneous delivery.

    Carriers of germline mutations in DNA mismatch repair (MMR) genes are at increased risk of several cancers including colorectal and gynecologic cancers (Lynch syndrome). There is no substantial evidence that these mutations are associated with an increased risk of cervical cancer. A total of 369 families with at least one carrier of a mutation in a MMR gene (133 MLH1, 174 MSH2, 35 MSH6 and 27 PMS2) were ascertained via population cancer registries or via family cancer clinics in Australia, New Zealand, Canada, and USA. Personal and family histories of cancer were obtained from participant interviews. Modified segregation analysis was used to estimate the hazard ratio (incidence rates for carriers relative to those for the general population), and age-specific cumulative risks of cervical cancer for carriers. A total of 65 cases of cervical cancer were reported (including 10 verified by pathology reports). The estimated incidence was 5.6 fold (95% CI: 2.3-13.8; p = 0.001) higher for carriers than for the general population with a corresponding cumulative risk to 80 years of 4.5% (95% CI: 1.9-10.7%) compared with 0.8% for the general population. The mean age at diagnosis was 43.1 years (95% CI: 40.0-46.2), 3.9 years younger than the reported USA population mean of 47.0 years (p = 0.02). Women with MMR gene mutations were found to have an increased risk of cervical cancer. Due to limited pathology verification we cannot be certain that a proportion of these cases were not lower uterine segment endometrial cancers involving the endocervix, a recognized cancer of Lynch syndrome.

    Uterine radioactivity uptake has previously been reported for a variety of radionuclide agents in the presence of uterine pathological disorders, such as leiomyomata as well as uterine and cervical neoplasma and infections. Activity within the normal uterus has also been reported in Meckel's scans using sup(99m)Tc-pertechnetate, but this has not been reported for other radionuclide agents. We report a case exhibiting radioactivity uptake within a normal uterus on a sup(99m)Tc-glucoheptonate scan of a renal transplant. Awareness of the possibility of radioactivity uptake in a normal uterus is important in order to avoid potential confusion with abnormal pelvic masses or fluid accumulations. (orig.).

  9. Carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    There are few reports on uterine cancer in relation to radiation. This chapter discusses uterine cancer in A-bomb survivors, with special reference to the mortality rate, in a review of the literature. The Atomic Bomb Casualty Commission has first discovered 28 cases of uterine cancer among A-bomb survivors during the period 1953-1957. Since 1970, mortality rate from uterine cancer has been investigated statistically according to the T65D system. The Radiation Effect Research Foundation (RERF) has revealed 282 death cases from uterine cancer during the period 1950-1974. The RERF's data up to 1982 has revealed no radiation-dependent mortality from uterine cancer. More recent data (1950-1985) has revealed that mortality rate was increased by 22% in A-bomb survivors exposed to 1 Gy or more. When mortality of uterine cancer was investigated statistically using the 1968-1982 data for the population of the Research Institute for Nuclear Medicine and Biology, Hiroshima University, it was 1.2 times higher in the entire exposed group and 1.4 times higher in the group of proximally exposed A-bomb survivors (within 2 km from the hypocenter) than the non-exposed group, with statistically significant difference. It tended to be high in the group of distally exposed A-bomb survivors (who entered the city within 3 days after A-bombing) than the non-exposed group. When comparing the group of Hiroshima City with the group of Hiroshima Prefecture, mortality from uterine cancer was 1.3 times higher in the municipal group for proximally exposed A-bomb survivors and 1.3 times higher in the prefectural group for distally exposed A-bomb survivors and the others. Mortality rate was highest within one year after the acquisition of health handbook in the exposed group. (N.K.)

    Full Text Available In a national program to combat cervical uterine cancer (CUC four basic elements should exist: primary prevention, early detection, diagnosis/treatment and palliative care. Of these, early detection is the most effective modality.

    Full Text Available OBJECTIVE: To evaluate pregnancy outcomes, complications and neonatal outcomes in women who had previously undergone uterine arterial embolization. METHODS: A retrospective study of 187 patients treated with uterine arterial embolization for symptomatic uterine fibroids between 2005-2008 was performed. Uterine arterial embolization was performed using polyvinyl alcohol particles (500-900 mm in diameter. Pregnancies were identified using screening questionnaires and the study database. RESULTS: There were 15 spontaneous pregnancies. Of these, 12.5% were miscarriages (n = 2, and 87.5% were successful live births (n = 14. The gestation time for the pregnancies with successful live births ranged from 36 to 39.2 weeks. The mean time between embolization and conception was 23.8 months (range, 5-54. One of the pregnancies resulted in twins. The newborn weights (n = 14 ranged from 2.260 to 3.605 kg (mean, 3.072 kg. One (7.1% was considered to have a low birth weight (2.260 kg. There were two cases of placenta accreta (12.5%, treated with hysterectomy in one case [6.3%], one case of premature rupture of the membranes (PRM (6.3%, and one case of preeclampsia (6.3%. All of the patients were delivered via Cesarean section. CONCLUSION: In this study, there was an increased risk of Cesarean delivery. There were no other major obstetric risks, suggesting that pregnancy after uterine arterial embolization is possible without significant morbidity or mortality.

  11. The treatment of uterine sarcomas.

    Science.gov (United States)

    Reichardt, P

    2012-09-01

    Uterine sarcomas are rare and comprise only 3% of all uterine cancers. Within the group of adult soft tissue sarcomas, they account for ?7% of new cases. They consist of several distinct histological subtypes like leiomyosarcoma, endometrial stromal tumors, undifferentiated sarcomas, pure heterologous sarcomas, and mixed epithelial and mesenchymal tumors. Standard treatment in localized disease is abdominal hysterectomy. Bilateral salpingo-oophorectomy and lymphadenectomy have no proven value in leiomyosarcomas and high-grade undifferentiated sarcomas. However, in endometrial stromal tumors, given the hormonal reponsiveness of most tumors, salpingo-oophorectomy is generally recommended. Carcinosarcomas are treated according to current recommendations for epithelial uterine cancers. In leiomyosarcomas, postoperative radiation does not improve both relapse-free and overall survival. adjuvant chemotherapy seems to improve survival in the context of uncontrolled phase II trials. However, it is currently not considered standard of care in the absence of data from randomized trials. In contrast, adjuvant chemotherapy does improve overall survival in carcinosarcomas and is therefore considered standard of care. Systemic therapy for advanced uterine leiomyosarcomas, undifferentiated uterine sarcomas, and heterologous sarcomas is generally following the recommendations for adult soft tissue sarcomas. Endometrial stromal sarcomas are usually hormonal receptor positive, which allows endocrine therapy in most cases. PMID:22987952

  14. Erosion protection

    International Nuclear Information System (INIS)

    All earth dams require protection against erosion due to wave action on the upstream slope and protection against runoff from rain, snowmelt or wave splash on the downstream shell. Erosion protection is a major cost factor in embankment dams, typically varying from 5-15% of the dam cost, although it can approach 50% of embankment cost for long low dikes. The most common type of erosion protection is dumped rock riprap. Current practice in riprap design is based on rational analysis of factors affecting riprap stability, and the performance of existing riprap protection. Historical development of riprap design is reviewed, beginning with U.S. Army Corps of Engineers dams in the 1940s. Riprap design parameters are based on slope steepness and severity of wave action, which depends on reservoir geometry and location. A common cause of riprap deterioration is loss of underlying bedding as a result of inadequate design or segregation of riprap and bedding during construction. The most common form of riprap failures include: loss of filter material through riprap if it is too fine; inadequate rock size to resist wave action, resulting in beaching; segregation during construction, resulting in pockets of undersized rock which can expose the underlying filter, and pockets of oversized rock through which bedding can wash out; breakdown of poor quality stone due to prolonged exposure and wave action; and failure to extend the primary riprap far enough downslope to be below the level of wave action at low reservoir levels. 26 refs., 8 figs

  16. Correlation of Traditional Point a With Anatomic Location of Uterine Artery and Ureter in Cancer of the Uterine Cervix

    International Nuclear Information System (INIS)

    Purpose: Point A, used for dose specification for intracavitary brachytherapy for cervical cancer, is the point at which the uterine artery and ureter cross. This study assessed compatibility of commonly used traditional point A (TPA) and actual anatomic point A (APA). Methods and Materials: We visualized and placed radiopaque clips at the APA during pelvic and paraaortic lymphadenectomy in 11 patients with cervical carcinoma. Orthogonal and oblique radiographs were obtained after insertion of brachytherapy applicators. We measured the distance between the TPA and APA and estimated the brachytherapy dose to each of the two points. Results: A total of 64 brachytherapy treatments were performed. The mean distances between the TPA and APA were 5.2 ± 1.0 cm on the right and 5.4 ± 1.1 cm on the left. The estimated brachytherapy doses delivered to the APA as a percentage of the presumed 500-cGy fraction size to the TPA were 35.2% (176.6 ± 59.0 cGy) on the right and 30.0% (150.2 ± 42.9 cGy) on the left. The marked discrepancy in the position of the two points was not related to individual kinetic variations during brachytherapy treatment, tumor size, or bladder filling. Conclusions: The conventional TPA does not provide an accurate estimate of the APA determined during lymphadenectomy, indicating a need to reevaluate the current practice for determining the brachytherapy prescription for cervical cancer.

  17. Concurrent chemoradiation therapy for advanced cervical cancer

    International Nuclear Information System (INIS)

    In 2003, we began a clinical application of concurrent chemoradiation therapy (CCR) in patients with cervical cancer in our hospital. We analyzed 14 cases of advanced cervical cancer in stages IIa through IIIb by International Federation of Gynecology and Obstetrics (FIGO) classification. Tumor size of the uterine cervix ranged from 1.5 cm to 8.0 cm in diameter. Patients received radiation therapy (50 Gy of external beam radiotherapy for pelvis and 20 Gy of high-dose rate intracavitary brachytherapy) combined with chemotherapy. Cisplatin was administered intravenously every 3 weeks at a dose of 70 mg/m2 during the radiation therapy. In two cases, CCR was stopped because of the side effects. One case developed acute renal failure and another suffered intolerable exhaustion. As for the antitumor effects of CCR, the response rate was 75% (complete response (CR) 58.3%, partial response (PR) 16.7%). At the end of the CCR, 10 of 12 patients (83.3%) were negative for viable cells by cytology or biopsy of the uterine cervix. The grade 3 adverse effects were leukopenia, diarrhea and anemia. There was no statistical difference in the overall survival between CCR and radiation therapy alone. The CCR response rate in patients with paraaortic lymph node swelling (suspected metastasis) was low, and they had a poor prognosis. Further examinations for the long-term survival benefit of CCR are necessary. (author)

    2011-01-01

    Uterine Cervical Cancer is one of the most common forms of cancer in women worldwide. Most cases of cervical cancer can be prevented through screening programs aimed at detecting precancerous lesions. During Digital Colposcopy, colposcopic images or cervigrams are acquired in raw form. They contain specular reflections which appear as bright spots heavily saturated with white light and occur due to the presence of moisture on the uneven cervix surface and. The cervix region occupies about half of the raw cervigram image. Other parts of the image contain irrelevant information, such as equipment, frames, text and non-cervix tissues. This irrelevant information can confuse automatic identification of the tissues within the cervix. Therefore we focus on the cervical borders, so that we have a geometric boundary on the relevant image area. Our novel technique eliminates the SR, identifies the region of interest and makes the cervigram ready for segmentation algorithms.

  2. Paraaortic lymph node irradiation in cervical carcinoma without prior lymphadenectomy

    International Nuclear Information System (INIS)

    A study of complications associated with paraaortic irradiation was undertaken in patients with uterine cervical cancer who had not undergone prior lymphadenectomy. Between 1975 and 1984, 29 highly selected patients received paraaortic irradiation as part of their definitive treatment for cervical carcinoma. Paraaortic fields were irradiated to a total dose of 4,200-5,000 rad (42-50 Gy), in fractions of 150-180 rad (1.5-1.8 Gy). An anteroposterior-posteroanterior technique was generally used. All fields were treated every day. There were no instances of small-bowel obstruction or other major complications, surgical procedures, or deaths caused by paraaortic irradiation. Eleven patients (38%) have no evidence of recurrent disease 23-120 months after completion of therapy. Paraaortic irradiation was well tolerated in this patient group without prior staging lymphadenectomy. Thus, in selected patients and with appropriate techniques, paraaortic irradiation for cervical carcinoma may be used with relative safety

  3. Endometrial cancer with cervical extension mimicking dual concordant endometrial and cervical malignancy by F18 FDG PET and MRI

    International Nuclear Information System (INIS)

    A 35 year old woman with endometrial cancer and cervical extension underwent F18 FDG PET CT and MRI studies after resection of a cervical mass presumed to be cervical myoma. The patient underwent cervical myomectomy and the histopathologic report revealed poorly differentiated invasive carcinoma. Cervical cancer was ruled out because the patient had no history of sexual intercourse and was negative for human papilloma virus infection. The patient underwent radical hysterectomy, bilateral salpingo oophorectomy, pelvic and para aortic lymph node dissection, and multiple biopsies. F18 FDG PET CT showed intense FDG uptake along the cervix wall. T2 weighted MRI also revealed a mass lesion with high SI involving the anterior and posterior lips of the uterine cervix. Another area of focal increased uptake above the endometrial lesion in the left pelvic cavity was observed on PET CT and MRI, possibly due to a functioning ovary. PET CT and MRI were interpreted as showing a dual concordant malignant lesion due to separated FDG uptakes and high SI without any connection between the cervical and endometrial lesions. F18 FDG PET CT showed intense FDG uptake along the endometrium. Given the patient's history and the fact that she was not menstruating at the time of imaging, this intense uptake was interpreted as another pathologic lesion, suggesting dual primary lesions. A suspected heterogeneous mass lesion along the endometrium suggesting concordant endometrial cancer was found on MRI. Endometrial cancer with cervical extension is sometimes difficult to differentiate from primary cervical cancer. The final histopathologic report showed poorly differentiated endometrial adenocarcinoma with cervical extension, although the FDG PET CT and MRI findings were suggestive of concordant cervical and endometrial cancer. Although histopathologic confirmation is necessary for final diagnosis, MRI and FDG PET CT studies may aid in the differential diagnosis. A metastatic cervical mass from endometrial cancer clinically presenting as cervical myoma is rare. This case suggests that poorly differentiated endometrial cancer may extend into the cervix, presenting as cervical myoma, and the possibility of a metastatic mass should be considered in the differential diagnosis when dealing with cervical myoma

  5. Papillary thyroid carcinoma with massive metastasis in the uterine corpus: a case report

    International Nuclear Information System (INIS)

    Distant metastases stemming from a papillary thyroid carcinoma (PTC) are quite rare. Here we report an exceptional case of PTC presenting with cervical lymphatic and uterine metastases. This is the first case report of a PTC with uterine involvement. A 60-year-old Chinese woman came to our hospital complaining of discomfort in the throat that she had been experiencing for about half a month. PTC and cervical lymphatic metastasis were diagnosed after ultrasound examinations. A massive heterogeneous mass was found beside the uterus during the pre-operative checkup and a diagnosis of ovarian carcinoma was suspected after a thorough case discussion. However, it proved to be a metastasis from the PTC as determined by pathological and immunohistochemical examinations after the operation. The patient declined further treatments. She was followed for 22 months with no sign of recurrence detected. In this report, an unusual case of PTC was presented. The patient had not only regional lymphatic metastasis, but also had a massive metastasis in the uterine corpus, which was initially misdiagnosed as ovarian carcinoma. This case is of interest because of its rarity and exceptionally good prognosis. The reason for the misdiagnosis was attributed to overlooking the possibility of a distant metastasis coming from a PTC. This case raises the issue that completing an iodine-131 scan before operating on patients with PTC may be warranted

  6. Identification of biomechanical properties in vivo in human uterine cervix

    Liao, Donghua; Hee, Lene

    2014-01-01

    BACKGROUND AND AIMS: The course and outcome of pregnancy is closely correlated to change of biomechanical properties of the uterine cervix. The aim of this study was to build a non-linear, fiber reinforced mechanical model of the cervix for estimation of mechanical characteristics of the cervix in early- and term-pregnant women based on recordings of in vivo pressure and diameter by means of the Functional Luminal Imaging Probe (FLIP) technology. MATERIALS AND METHODS: Five early- and six term-pregnant women were examined with a FLIP probe. The bag on the probe was inserted into the cervical canal for concomitant measurement of diameters at 16 serial locations along the canal and the bag pressure. The bag was inflated to a maximum volume of 50ml. A three-fiber-families model including isotropic elastin-dominated matrix and anisotropic collagen was introduced to describe the mechanical behavior of the cervical canal. The unknown geometric and mechanical parameters were calculated on the basis of the mid-cervical diameters and the intraluminal pressures during the inflation. RESULTS: The wall thickness in the unloaded state (zero pressure applied) and mechanical properties of the matrix material (c) and collagens (c1, c2) were estimated with good fits of the calculated intraluminal pressures to the FLIP recordings during the cervical canal distension. No significant difference in the wall thickness was found between the early- and term-pregnant women (10.3±0.8mm vs. 11.7±2.2mm, p=0.30). The cervical matrix material and the collagen in the early-pregnant women were much stiffer than that in the term-pregnant women (p<0.05). CONCLUSIONS: The cervical mechanical properties can be obtained from recorded pressure and diameter data in vivo via the established mechanical model. Matrix material and collagens of the cervix wall were remodeled during pregnancy. The mechanical model can be applied to other tubular visceral organs where concomitant measures of pressure and diameter can be obtained for better understanding diseases and their evolution or treatment.

    A case of uncommon occupational dental erosion was reported in an individual who had worked in the war industry for twenty years. This occupation involved daily, at least 8 hours, inhalation of chromic acid being used for cleaning of barrel of cannons. The erosion manifested as dental sensitivity with excessive cervical erosion even with pulpal exposure in certain teeth. Moreover, due to the adverse effect of the chemical against to gingival and/or periodontal tissues, the lesions were extrem...

  11. Adenocarcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    A retrospective analysis was performed to evaluate the prognosis significance of histologic type (epidermoid carcinoma versus adenocarcinoma) on local control of disease and on the development of distant metastatic disease in 1239 patients with carcinoma of the uterine cervix treated with radiation therapy alone or surgery and irradiation at the Radiation Oncology Center, Mallinckrodt Institute of Radiology (MIR), Washington University Medical Center, between 1959 and 1982. The data indicate that adenocarcinoma of the uterine cervix does not confer a worse prognosis than does epidermod carcinoma when all other factors are equal. Those factors most significant for survival are size of the primary lesion, dose at point A, and the presence of positive lymph nodes

OBJETIVO: Estudar a prevalência das alterações radiológicas de coluna cervical em pacientes com AR e sua associação com perfil clinico e sorológico da doença. MÉTODOS: Analisaram-se as radiografias de coluna cervical e [...] m perfil neutro hiperextensão, hiperflexão e transoral de 80 pacientes com AR para presença de subluxação atlanto-axial (LAA), invaginação basilar (IB) e instabilidade subaxial (ISA). Dados de perfil demográfico, clínico (nódulos, pneumonite intersticial, síndrome Sjögren secundária, uso de medicamentos etc.) e sorológico (FR, anti-CCP e FAN) foram obtidos por revisão de prontuários. RESULTADOS: Havia alguma alteração de eixo de coluna cervical em 26/80 (32,5%); em 12/80 (15%) havia LAA; em 6/80(7,5%) existia IB; em 13/80 (16,2%) existia ISA. Erosões em odontoide foram vistas 16/80 (20,0%). As alterações do eixo cervical estavam associadas com idade de início da doença e duração da mesma (P = 0,03 e 0,02, respectivamente). Não se encontrou associação das alterações em coluna cervical com raça, gênero, nódulos, pneumonite intersticial, Sjögren secundário, FR, FAN ou anti-CCP. Pacientes com alterações do eixo cervical apresentavam mais erosões de odontoide (P = 0,03). CONCLUSÕES: Alterações radiológicas em eixo de coluna cervical são comuns e aparecem mais frequentemente em indivíduos com diagnóstico mais precoce de AR e maior tempo de doença. Abstract in english INTRODUCTION: The involvement of the cervical spine is a common feature of rheumatoid arthritis (RA). OBJECTIVE: To study the prevalence of radiographic changes of the cervical spine in patients with RA and their association with clinical and serological profiles of the disease. METHODS: We analysed [...] lateral (neutral position, hyperextension, hyperflexion) and transoral views of cervical spine radiographs from 80 individuals with RA to investigate the presence of atlanto-axial subluxation (AAS), basilar invagination (BI), and subaxial instability (SAI). Demographic, clinical (nodules, interstitial pneumonitis, secondary Sjögren's syndrome, medications etc.), and serologic (rheumatoid factor - RF, cyclic citrullinated peptide antibody - anti-CCP, and antinuclear factor - ANF) data were obtained from the clinical records. RESULTS: Cervical spine misalignments were identified in 26/80 (32.5%) participants; AAS occurred in 12/80 (15%) participants, BI in 6/80 (7.5%), and SAI in 13/80 (32.5%). Odontoid erosions were identified in 16/80 (20.0%) participants. Cervical spine misalignment exhibited associations with age at onset and disease duration (P = 0.03 and 0.02, respectively). No associations were identified between the cervical spine changes and the participants' ethnicity or gender, presence of nodules, interstitial pneumonitis, secondary Sjögren's syndrome, RF, ANF, or anti-CCP. The participants with cervical spine misalignment exhibited higher frequencies of odontoid erosion (P = 0.03). CONCLUSIONS: Cervical spine misalignment was a common radiographic finding and occurred more frequently in participants with earlier onset and longer length of RA.

    The concentration of cytoplasmic estrogen receptors (ER) in cancer of the uterine cervix was measured in 30 cases (28 squamous cell carcinomas and 2 adenocarcinomas). The mean ER concentration in squamous cell carcinoma was 19.3 +/- 26.0 fmol/mg cytosol protein; for pre- and postmenopausal women 6.82 +/- 9.86 and 28.6 +/- 30.1 fmol/mg protein, respectively, were found, the latter being significantly higher. When 'ER-positive' was defined as concentrations greater than 10 fmol/mg protein, 12 of the 28 cases (43%) were found to be ER-positive. There were no significant differences between the ER concentrations of clinical stage I and II squamous cell carcinomas (19.2 +/- 24.2 and 20.9 +/- 27.2 fmol/mg, respectively). ER were detectable in the cervical tissue from all of the control cases of myoma of the uterus. There were, however, no differences in the ER content between the proliferative and secretory phases, but the concentration in premenopausal women was significantly lower than that in postmenopausal women. In comparison with the controls, the mean ER level in both pre- and postmenopausal women with squamous cell carcinoma was significantly lower, due to the fact that ER were not detectable in 57% of these cases. Both cases of cervical adenocarcinoma were ER-positive. PMID:4054727

    Giant erosive spinal schwannomas can be distinguished from other spinal schwannomas by its growth in myofascial planes and vertebral body erosion. Therapeutic radical tumour excision without neurologic deterioration is possible in the management. Prognosis is good after total tumour removal. In this article, it is aimed to report six patients who were diagnosed as giant erosive spinal schwannomas between 2001 and 2004 according to the criteria of Sridhar et al. Three of the patients were male and three female with the age range of 16-63 (mean age 39.7). Three of the tumours were located in the cervical region, one in the lumbar region, one in the thoracic region and one in the sacral region. Total excision of the tumours was achieved in four patients. However, one additional operation was required in two patients. Follow-up periods ranged from 6 weeks to 7 years (mean follow-up 51 months). Four patients had a good clinical outcome and there were no radiologic signs of instability or recurrence. Our experience and other published literature suggest that giant erosive spinal schwannoma has significant features such as local invasive nature together with vertebral body erosion and large size but benign histology, long duration for clinical presentation, common preoperative misdiagnosis and good prognosis after total excision. These tumours rarely need spinal instrumentation because the disc capsule and ligaments remain intact even if the pedicle and posterior elements are compromised. PMID:20515264

  9. Cervical stiffness evaluated in vivo by endoflip in pregnant women

    DEFF Research Database (Denmark)

    Hee, Lene; Sandager, Puk

    2014-01-01

    OBJECTIVE: To determine the stiffness of the pregnant uterine cervix in vivo. METHOD: Five women in early pregnancy and six women in late pregnancy were included. The EndoFlip is a 1-m-long probe with a 12-cm-long bag mounted on the tip. The tip of the probe was inserted into the cervical canal. Sensors spaced at 0.5-cm intervals along the probe were used to determine 16 serial cross-sectional areas of the bag. The diameter of the cervical canal could thereby be determined during inflation with up to 50 ml saline solution. Tissue stiffness was calculated from the geometric profiles and the pressure-strain elastic modulus (EP) at each sensor site. Three parts of the cervix were defined: the uterus-near part, the middle and the vaginal part. The EPmax was defined as the highest EP detected along the cervical canal. RESULTS: The EPmax was always found in the middle part of the cervix. The median EPmax was 243 kPa (IQR, 67-422 kPa) for the early pregnant women and 5 kPa (IQR, 4-15 kPa) for those at term. In theearly pregnant women the stiffness differed along the cervical length (p<0.05) whereas difference along the cervix was not found for late pregnant women. A positive correlation coefficient (Spearman's rho) was established between the EPs of the uterus-near and the middle part (0.84), between the vaginal and the middle part (0.81), and between the uterus-near and the vaginal part (0.85). CONCLUSION: This new method can estimate the stiffness along the cervical canal in vivo. This method may be useful in the clinical examination of the biomechanical properties of the uterine cervix.

    2008-01-01

    Full Text Available Despite advances in the treatment modalities, cervical cancers are one of the leading causes of cancer death among women. Pap smear and colposcopy are the existing screening methods and histopathology is the gold standard for diagnosis. However, these methods have been shown to be prone to reporting errors, which could be due to their subjective interpretation. Radiotherapy is the mainstay of treatment for the locally advanced stages of cervical cancers. The typical treatment regimen spans over 4 months, from the first fraction of radiation to clinical assessment of tumor response to radiotherapy. It is often noticed that due to intrinsic properties of tumors, patients with the same clinical stage and histological type respond differently to radiotherapy. Hence, there exists a need for the development of new methods for early diagnosis as well as for early prediction of tumor radioresponse. Optical spectroscopic methods have been shown to be potential alternatives for use in cancer diagnosis. In this review, we provide a brief background on the anatomy and histology of the uterine cervix and the etiology of cervical cancers; we briefly discuss the optical spectroscopic approach to cervical cancer diagnosis. A very brief discussion on radiation therapy and radiation resistance is also provided. We also share our experiences with the Raman spectroscopic methodologies in cervical cancer diagnosis as well as in the prediction of tumor radioresponse.

    Full Text Available Uterine sarcomas are rare tumours of mesodermal origin. Malignant change occurring in uterine fibroid is termed as leiomyosarcoma. They constitute around 2-6 % uterine malignancies and 25-36% of uterine sarcomas1. The tumour is common in women between the age group 40-50 years. It has an aggressive course and usually metastasis goes to the lungs. The prognosis for women with uterine sarcoma primarily depends on the extent of disease at the time of diagnosis and mitotic index3. Women with tumor size >5 cm in maximum diameter have poor prognosis. These tumours should be diagnosed and managed with no delay and must be followed vigilantly as the rate of recurrence and metastasis is very high.

Their mean age at disease onset was 41.4+ 13.4 years (range of 18-73)and mean duration of disease was 9.1+-6.28 years (range of 2-34). Their demographic data including rheumatoid factor status was obtained. Standard conventional radiographs cervical spine were obtained to study the cervical spine changes. Cervical radiographic changes were found in 34 patients (27 females and 7 males) 10 had subluxation (7 with atlanto-axial subluxation,2 with sub-axial subluxation,and one with lateral subluxation ). No vertical impaction was seen. Erosion of odontoid process was seen in one patient .All were rheumatoid seropositive Cervical spine changes in patients with rheumatoid arthritis are common, in particular subluxation in the upper cervical spine. Our study showed somewhat lesser prevalence of these changes. These were clinically correlated with disease duration, female sex, and rheumatoid factor, but were not clinically significant. (author)

    The classic approach of detection of pre-cancer and cancer of uterine cervix includes cytological examination, followed by colposcopy assessment of the detected cytological abnormalities. Real-time devices use in-vivo techniques for the measurement, computerized analysis and classifying of different types of cervical tissues. The aim of the present review is to present the technical characteristics and to discus the diagnostic possibilities of TruScreen-automated optical-electron system for cervical screening. The analysis of the presented in the literature diagnostic value of the method at different grades intraepithelial lesions shows that it has higher sensitivity (67-70%) and lower specificity (81%) in comparison to the Pap test with the following results (45-69% sensitivity and 95% specificity). This makes the method suitable for independent primary screening, as well as for adding the diagnostic assurance of the cytological method. PMID:20225497

    To establish the prognostic parameters of DNA distributions of squamous-cell carcinomas of the uterine cervix, cervical smears from 30 patients were examined cytomorphometrically ten years after the diagnosis had been made. Most of the patients had stage II cervical carcinomas that had been treated with primary combined irradiation. In the DNA histograms, the position of the stemline proved to be the prognostically significant factor. All of the patients with diploid or euploid-polyploid stemlines were still alive after ten years while only 17.6% of those with aneuploid stemlines have survived. No correlation between the ten-year survival rate and the proliferation rate of the tumors could be established. PMID:3730088

    Earthquakes build topography but also drive erosion. Erosion, in turn, may control seismicity. Nowhere is this two way feedback more evident than in Taiwan. There, patterns of erosion and seismicity are demonstrably correlated, over decades and also at the scale of individual, large earthquakes. At the scale of the mountain belt, the pattern of erosion shares elements with the distribution of cumulative seismic mo- ment, and the relative importance of typhoons. Are these controls independent,...

  7. Rectal sonography before and after radiation treatment in inoperable cervical cancer

    International Nuclear Information System (INIS)

    Transrectal sonography is helpful in the classification of parametrial infiltration prior to treatment as well as in the follow-up. In this study, we performed rectal sonography in cases of inoperable cervical cancer to objectify the reduction of the infiltration of the uterine cervix and of the parametrium. Rectosonography was performed in 10 patients with histologically confirmed cancer of the uterine cervix before and after radiation treatment. The patients were treated with brachytherapy and teletherapy with an average radiation dose of 7680 rad. The whole therapy was finished after 6 to 9 weeks. Rectosonography enabled us to objectify the effect of radiation therapy. The length and width of parametrial infiltration could be measured in relation to the pelvis wall. Furthermore, the configuration of the parametrium could be imaged. Therefore, in cervical cancer, rectosonography is a valuable method to check and the documentate the effect of treatment and to diagnose recurrency. (orig.)

    Information is still being collected on the long-term clinical responses and appropriate patient selection for UAE. Prospective RCTs have not been performed to compare the clinical results from UAE with more conventional therapies for symptomatic uterine leiomyomata. At least three attempts at conducting such RCTs have been unsuccessful because of poor patient accrual that related to differing patient expectation and desires, clinical bias, insurance coverage, and the tendency that patients who have exhausted other treatment options may be disposed more favorably to less invasive treatments. Other comparative studies have serious limitations. For example, the retrospective study that compared outcomes after abdominal myomectomy with UAE suggested that patients who received UAE were more likely to require further invasive treatment by 3 years than were recipients of myomectomy. Lack of randomization introduced a selection bias because women in the group that underwent UAEwere older and were more likely to have had previous surgeries. A prospective study of "contemporaneous cohorts," which excluded patients who had sub-mucosal and pedunculated subserosal myomas, sought to compare quality of life measures and adverse events in patients who underwent UAE or hysterectomy. The investigators concluded that both treatments resulted in marked improvement in symptoms and quality of life scores, but complications were higher in the group that underwent hysterectomy over 1 year. In this study,however, a greater proportion of patients who underwent hysterectomy had improved pelvic pain scores. Furthermore, hysterectomy eliminates uterine bleeding and the risk for recurrence of myomas. Despite the lack of controlled studies that compared UAE with conventional surgery, and despite limited extended outcome data, UAE has gained rapid acceptance, primarily because the procedure preserves the uterus, is less invasive, and has less short-term morbidity than do most surgical options. The cost of UAE varies by region, but is comparable to the charges for hysterectomy and is less expensive than abdominal myomectomy. The evaluation before UAE may entail additional fees for diagnostic testing, such as MRI, to assess the uterine size and screen for adenomyosis. Other centers have recommended pretreatment ultrasonography, laparoscopy, hysteroscopy, endometrial biopsy, and biopsy of large fibroids to evaluate sarcoma. Generally,after UAE the recovery time and time lost from work are less; however, the potential need for subsequent surgery may be greater when compared with abdominal myomectomy. Any center that offers UAE should adhere to published clinical guidelines,maintain ongoing assessment of quality improvements measures, and observe strict criteria for obtaining procedural privileges. After McLucas advocated that gynecologists learn the skill to perform UAE for managing symptomatic myomas, the Society of Interventional Radiology responded with a precautionary commentary on the level of technical proficiency that is necessary to maintain optimum results from UAE. The complexity of pelvic arterial anatomy, the skill that is required to master modern coaxial microcatheters, and the hazards of significant patient radiation exposure were cited as reasons why sound training and demonstration of expertise be obtained before clinicians are credentialed to perform UAE.A collaboration between the gynecologist and the interventional radiologist is necessary to optimize the safety and efficacy of UAE. The primary candidates for this procedure include women who have symptomatic uterine fibroids who no longer desire fertility, but wish to avoid surgery or are poor surgical risks. The gynecologist is likely to be the primary initial consultant to patients who present with complaints of symptomatic myomas. Therefore, they must be familiar with the indications, exclusions, outcome expectations, and complications of UAE in their particular center. When hysterectomy is the only option, UAE should be considered. Appropriate diagnostic testing should ai

    Full Text Available Endometrial and cervical cancers, uterine myoma, and endometriosis are very common uterine diseases. Worldwide, more than 800,000 women are affected annually by gynecological cancers, as a result of which, more than 360,000 die. During their reproductive age, about 70% of women develop uterine myomas, 10% to 15% suffer from endometriosis, and 35% to 50% from infertility associated with endometriosis. Uterine diseases are associated with aberrant inflammatory responses and concomitant increased production of prostaglandins (PG. They are also related to decreased differentiation, due to low levels of protective progesterone and retinoic acid, and to enhanced proliferation, due to high local concentrations of estrogens. The pathogenesis of these diseases can thus be attributed to disturbed PG, estrogen and retinoid metabolism and actions. Five human members of the aldo-keto reductase 1B (AKR1B and 1C (AKR1C superfamilies, i.e., AKR1B1, AKR1B10, AKR1C1, AKR1C2 and AKR1C3, have roles in these processes and can thus be implicated in uterine diseases. AKR1B1 and AKR1C3 catalyze the formation of PGF2alpha which stimulates cell proliferation. AKR1C3 converts PGD2 to 9alpha,11beta-PGF2, and thus counteracts the formation of 15deoxy-PGJ2, which can activate pro-apoptotic peroxisome-proliferator-activated receptor beta. AKR1B10 catalyzes the reduction of retinal to retinol, and in thus lessens the formation of retinoic acid, with potential pro-differentiating actions. The AKR1C1-AKR1C3 enzymes also act as 17-keto- and 20-ketosteroid reductases to varying extents, and are implicated in increased estradiol and decreased progesterone levels. This review comprises a short introduction to uterine diseases, followed by an overview of the current literature on the AKR1B and AKR1C expression in the uterus and in uterine diseases. The potential implications of the AKR1B and AKR1C enzymes and their pathophysiologies are then discussed, followed by conclusions and future perspectives.

  11. Treatment of uterine leiomyoma with magnetic resonance-guided focused ultrasound surgery (MRgFUS)

    International Nuclear Information System (INIS)

    Uterine leiomyoma is the most common pelvic tumor in women. Although hysterectomy has long been the standard treatment for uterine myoma, some uterus-preserving alternatives are available today. Among these, magnetic resonance-guided focused ultrasound surgery (MRgFUS) is a minimally-invasive procedure that uses high intensity ultrasound waves to ablate tissue. The present study investigates the efficacy of MRgFUS in the treatment of uterine myoma and the histopathological features on extirpated myoma tissue, when alternative surgical treatment is requisite. The Ethics Committee of Shinsuma Hospital approved the treatment of uterine myoma by MRgFUS, and written informed consent was obtained from all of the patients in compliance with the principles of good clinical practice. Between June 2004 and March 2007, 81 premenopausal patients with 125 myomas confirmed by T2-weighted MRI were treated by MRgFUS. The myomas were classified into 3 types based on signal intensity of T2-weighted images type I, low intensity; type II, intermediate intensity and type III, high intensity. The ablation (the non-perfused ratio of gadolinium injection) was about 55% in type I and type II, and 38% in type III. There was no correlation between the ablation ratio and the location or the size of the myoma. The uterine muscle was spared ablation when 2 combined myomas were treated as one tumor, suggesting that the vascularity was richer in the uterine muscle layer than in the myoma Sufficient ablation of the myoma near the Os sacrum is not able to attain immediately after the treatment; however, in several cases a complete non-perfusion margin was observed 3 or 6 months after the treatment. These cases yield very satisfactory results and it is meaningful to search for the reason why such good results were induced. Alternative treatment such as hysterectomy, myomectomy, trans cervical resection (TCR) or uterine artery embolization (UAE) was indicated for 13.6% of the patients. Here, we demonstrate a case of leiomyosarcoma disclosed after MRgFUS and display T2-weighted schemas of myoma and leiomyosarcoma before and 6 months after treatment, attesting to the essentiality of follow-up after the procedure. MRgFUS was of little effect in cases of cellular leiomyoma in which regrowth of leiomyoma cells was observed at the periphery of the myoma. Necl-2 and COX-2 were positive in cellular leiomyoma tissue, as are myogenic stem cells in skeletal muscle. Moreover, numerous mast cells and abundant vascularity was found in cellular leiomyomas. These results suggest that cellular leiomyoma and myoma with hypervascularity or degenerative changes are resistant to MRgFUS treatment. (author)

    This study was undertaken to evaluate the efficacy of postoperative radiotherapy, and to investigate the prognostic factors for FIGO stages IB-IIB cervical cancer patients who were treated with simple hysterectomy, or who had high-risk factors following radical hysterectomy and pelvic lymph node dissection. Between March 1986 and December 1998, 58 patients, with FIGO stages IB-IIB cervical cancer were included in this study, The indications for postoperative radiation therapy were based on the pathological findings, including lymph node metastasis, positive surgical margin, parametrial extension, Iymphovascular invasion, invasion of more than half the cervical stroma, uterine extension and the incidental finding of cervix cancer following simple hysterectomy. All patients received external pelvic radiotherapy, and 5 patients, received an additional intracavitary radiation therapy. The radiation dose from the external beam to the whole pelvis was 45 - 50 Gy. Vagina cuff irradiation was performed, after completion of the external beam irradiation, al a low-dose rate of CS-137, with the total dose of 4488-4932 chy (median: 4500 chy) at 5 mm depth from the vagina surface. The median follow-up period was 44 months (15-108 months), The 5-yr actuarial local control rate, distant free survival and disease-free survival rate were 98%, 95% and 94%, respectively. A univariate analysis of the clinical and pathological parameters revealed that the clinical stage (p=0.0145), status of vaginal resection margin (p=0.0002) and parametrial extension (p=0.0001) affected the disease-free survival. From a multivariate analysis, only a parametrial extension independently influenced the disease-free survival. Five patients (9%) experienced Grade 2 late treatment-related complications, such as radiation proctitis (1 patient), cystitis (3 patients) and lymphedema of the leg (1 patient). No patient had grade 3 or 4 complications. Our results indicate that postoperative radiation therapy can achieve good local control and survival rates for patients with stages IB-IIB cervical cancer, treated with a simple hysterectomy, as well as for those treated with a radical hysterectomy, and with unfavorable pathological findings. The prognostic factor for disease-free survival was invasion of the parametrium. The prognostic factor identified in this study for treatment failure can be used as a selection criterion for the combined treatment of radiation and chemotherapy.

    Leiomyomas are the most common benign uterine tumor; however, this entity is relatively uncommon in the pediatric population. Although leiomyomas most commonly present as solitary uterine masses, unusual patterns of growth have been described including diffuse leiomyomatosis. In this condition, the myometrium of the uterus is symmetrically expanded by innumerable confluent leiomyomas; this pattern of growth is quite uncommon and has never been reported in a pediatric patient. This case report illustrates the imaging appearance of diffuse uterine leiomyomatosis in an otherwise healthy 16-year-old girl. (orig.)

    Full Text Available Abstract Simultaneous occurrence of early microinvasive endometrioid adenocarcinoma (EMEA and CIN 3 in the uterine cervix is very rare in Japan. A 32-year-old Japanese woman was pointed out to have atypical cells in the cervical cytology. Colposcopic examination revealed irregular lesions in the cervix, and a biopsy showed simultaneous EMEA and CIN3. The EMEA was grade I and CIN3 corresponded to severe dysplasia/carcinoma in situ. Hysterectomy and lymph nodes dissection were performed. Grossly, mucosal irregularity and erosion were seen in the cervix. No tumor formation was recognized. The cervix was examined by serial sections. Microscopically, there were a tiny adenocarcinoma (0.5 cm in diameter and 0.3 cm in depth and broad areas of CIN3. The adenocarcinoma was EMEA without mucins. The EMEA was FIGO stage 1A1. Immunohistochemically, the EMEA was positive for pancytokeratins (AE1/2 +++, CAM5.2 ++, cytokeratin (CK 34?E12 +, CK5/6 +, CK7 +, CK18 +++, CK19 ++, CA19-9 +, CA125 +++, p53 +, ER +++, PgR +++, while it was negative for CK8, CK14, CK20, EMA, vimentin, CEA, desmin, smooth muscle actin, p63, chromogranin, synaptophysin, CD56, CD68, HER2/neu, MUC1, MUC2, MUC5AC, and MUC6. The CIN 3 was positive for pancytokeratins (AE1/2 +++, CAM5.2 +, cytokeratin (CK 34?E12 +++, CK5/6 +++, CK7 +, EMA, CA19-9 +, CA125 +, p53 +, p63 +++, ER +++, and MUC1 +, while it was negative for CK8, CK14, CK18, CK19, CK20, vimentin, CEA, desmin, smooth muscle actin, chromogranin, synaptophysin, CD56, CD68, PgR, HER2/neu, MUC2, MUC5AC and MUC6.

    The study investigated the possibility of pharmacological servical ripening induced by Dinoprostone (Prepidil Gel--Upjohn Co) prior to therapeutic abortion in primigravida. The study concerned patients-volunteers choosen by random. 73 patients were divided into two groups with the same average age, term of gestation, cervix consistency and passage through the cervical canal before the application of gel. In the first group therapeutic abortion was carried out 6 hours after the application of gle into cervical canal, and in the second group--4 hours after the gel application. Cervical maturation, testified by its consistency and spontaneous cervical ripening, was equal in both groups (average delta Hegar I was 7.32 and delta Hegar II--7.02), and it enabled medical procedure only with the local anaesthesia with 2% hylocein in 82% ob pregnant women. In a fifth of patients ob both groups it was necessary to do additional mechanical dilatation, which was easily performed due to the already soft cervix; these patients were also administered 1 ampulla ob Fortral I.V. In both groups during the action of Dinoprostone there were no significant changes either in blood pressure or in body temperature. More expressed uterine activity, followed by initial and incompleted abortions, were more frequent in patients of the first group (3529%) than in those from the second group (17.95%) in which only contractions occurred (33.33%). The rate of gastrointestinal side effects was 29.41% in the first group and 41.03% in the second group. There was no uterine complication during the activity of Dinoprostone as well as during and after medical procedure. PMID:2218733

    Full Text Available Mycotoxins are today considered one of the main contaminants of food and feed. Widespread zearalenone and its metabolites have potent estrogenic and anabolic activity, proven in numerous studies worldwide. The aim is to investigate influence of zearalenone on the uterine weight of rats depending on the applied dose and duration of the observation period. In a controlled experimental study, 63 adult female Wistar rats were divided into three groups, depending on the oral test dose of zearalenone applied: 0.1, 0.3 and 0.5 mg / kg of body weight. At the end of each of the four observation periods of seven days, animals were sacrificed under general anesthesia with ether, and after an autopsy the mass of the uterus was determined. Zearalenone in the dose of 0.1 mg / kg of body weight has caused a significant increase in uterine weight between the first and fourth observation interval. Doses of 0.3 and 0.5 mg zearalenone/ kg caused a decrease in uterine weight, which was at a dose of 0.5 mg / kg highly significant between all observational intervals. After 7 days of applying of the toxin, uterine weights did not differ significantly with respect to applied dose. After 14, 21 and 28 days, differences in uterine weight were highly significant, depending on the dose of zearalenone. The results show that prolonged application of large doses of zearalenone produced a significant decrease in uterine weights in experimental animals.

  1. The impact of Human papilloma virus (HPV infection on the development of cervical neoplasia

    Directory of Open Access Journals (Sweden)

    Vlad Gheorghita

    2008-08-01

    Full Text Available The genesis of uterine cervix carcinoma has as central etiology the active infection of human papilloma virus (HPV, especially high oncogenic risk subtypes. However, this is a necessary, but not sufficient cause of virtually all cases of cervical cancer worldwide. At present, the proportion of cervical carcinomas attributed to HPV infection is estimated at 99%. It is considered that the pathogenesis of cervical carcinoma is the result of the proliferation of one or, at most, a few HPV-infected cells. Invasive cervical cancer arises in cervical intraepithelial neoplasia, which in turn develops preferentially in squamous metaplasia of certain limited areas. These areas represent the most important morphologic characteristic in cervical intraepithelial neoplasia. It is still unknown the precise mechanism for the development of separate fields in HPV-related intraepithelial neoplasia and the variable susceptibility of reserve cells for different HPV genotypes. The goal of any cervical cancer screening test is to identify women who are at risk of cervical cancer development and to reassure others that do not belong to this category. Cervical cytology (Pap smears were the primary screening tests. More recently, carcinogenic HPV DNA testing has been included as adjunctive test or as a primary screening test based on the central role of carcinogenic HPV infection in the development of cervical cancer. New biomarkers, including those that measure the interaction of host and virus, are being considered either as stand-alone molecular assays or in conjunction with cytology or carcinogenic HPV DNA testing to improve its sensitivity or specificity, respectively. .Profilactic HPV vaccination of women who are sexually active may provide protection against HPV-16 or HPV-18 infection which may lead to cytological abnormalities, precancer or cancer.

    Lymph node dissection has proven prognostic benefits for patients with ovarian or uterine carcinoma; however, one of the complications associated with this procedure is lymphedema. We aimed to identify the factors that are associated with the occurrence of lymphedema after lymph node dissection for the treatment of ovarian or uterine carcinoma.

Among ovarian and uterine cancer patients who underwent pelvic lymph node dissection, post-operative radiotherapy (odds ratio: 1.79; 95% confidence interval: 1.20–2.67; p = 0.006) was statistically significantly associated with occurrence of lymphedema. There was no relationship between any surgical procedure and occurrence of lymphedema among patients undergoing pelvic lymphadenectomy. Our findings are supported by a sound biological rationale because they suggest that limb lymphedema is caused by pelvic lymph node dissection

    Purpose. -To identify prognostic factors and treatment toxicity in a series of operable stages IB and II cervical carcinomas. Patients and methods. - Between May 1972 and January 1994, 414 patients (pts) with cervical carcinoma staged according to the 1995 FIGO staging system underwent radical hysterectomy with (n=380) or without (n=34) bilateral pelvic lymph node dissection. Lateral ovarian transposition to preserve ovarian function was performed on 12 pts. The methods of radiation therapy (RT) were not randomized and depended on the usual practices of the surgical teams. Group I:168 pts received postoperative RT (64 pts received vaginal brachytherapy alone (mean total dose (MD): 50 Gy], 93 pts had external beam pelvis RT (EBPRT) [MD: 45 Gy over 5 weeks] followed by vaginal brachytherapy [MD: 20 Gy], and 11 pts had EBPRT alone [MD: 50 Gy over 6 weeks]. Group II: 246 pts received preoperative utero-vaginal brachytherapy [MD: 65 Gy], and 32 of theses 246 pts also received postoperative EBPRT [MD: 45 Gy over 5 weeks] delivered to the parametric and the pelvic lymph nodes with a midline pelvic shield. The mean follow-up was 106 months. Results. - The 10-year disease-free survival (DFS) rate was 80%. From 75 recurrences, 35 were isolated locoregional. Multivariate analysis showed that independent factors decreasing the probability of DFS were: both exo and endo-cervical tumour site (p=0.047), lymph-vascular space invasion (p=0.041), age {<=} 51 yr (p=0.013), 1995 FIGO staging system (stage IB1 vs stage IIA, p=0.004, stage IB1 vs stage IB2, p=0.0009, and stage IB1 vs stage IIB with 1/3 proximal parametrical infiltration, p=0.00002), and histological pelvic involved lymph nodes (p=0.00009). Methods of adjuvant RT did not influence the probability of DFS (group I vs group II, p=0.10). The postoperative complication rate was 10.2% in group I and 8.9% in group II (p=0.7) but the postoperative urethral complication rate necessitating surgical intervention with re-implantation was lower in group I than in group II (0.6% vs 2.3%, respectively, p=0.03). The 10-year rate for grade 3 and 4 late radiation complications according to the LENT-SOMA scoring system was 10.4%. EPRT significantly increased the 10-year rate for grade 3 and 4 late radiation complications (yes vs no: 22% vs 7%, respectively, p=0.0002). Conclusion. - In our series, the methods of adjuvant RT (primary surgery vs preoperative utero-vaginal brachytherapy) do not seem to influence the prognosis of the stage IB, IIA, and IIB - (with 1/3 proximal parametrical involvement only) cervical carcinomas. The postoperative EPRT applied according to histopathological risk factors after surgical treatment increases the risk of late radiation complications. (author)

  9. Uterine Artery Embolization to Treat Uterine Adenomyosis with or without Uterine Leiomyomata: Results of Symptom Control and Health-Related Quality of Life 40 Months after Treatment

    International Nuclear Information System (INIS)

    Purpose: To evaluate the clinical outcome for uterine adenomyosis with or without uterine leiomyomata 40 months after uterine artery embolization (UAE). Methods: Forty women aged 39–56 years (median 46 years) with symptomatic uterine adenomyosis and magnetic resonance imaging findings of uterine adenomyosis with or without combined uterine leiomyomata underwent UAE. Self-perceived changes in clinical symptoms were assessed, and residual symptom severity and health-related quality of life (HRQOL) after UAE were evaluated. Clinical failure was defined as no symptomatic improvement or second invasive therapy after UAE. Results were stratified by the extent of uterine adenomyosis at baseline magnetic resonance imaging. Results: Patients were followed for a median of 40 months (range 5–102 months). UAE led to symptomatic control after UAE in 29 (72.5%) of 40 patients while 11 women underwent hysterectomy (n = 10) or dilatation and curettage (n = 1) for therapy failure. No significant difference between women with pure uterine adenoymosis and women with uterine adenomyosis combined with uterine leiomyomata was observed. Best results were shown for UAE in uterine adenomyosis with uterine leiomyomata predominance as opposed to predominant uterine adenomyosis with minor fibroid disease (clinical failure 0% vs. 31.5%, P = 0.058). Throughout the study group, HRQOL score values increased and symptom severity scores decreased after UAE. Least improvement was noted for women with pure adenomyosis. Conclusions: UAE is clinically effective in the long term in most women with uterine adenomyosis. Symptomatic control and HRQOL were highest in patients with combined disease of uterine adenomyosis but leiomyomata predominance.

    Dental erosion develops through chronic exposure to extrinsic/intrinsic acids with a low pH. Enamel erosion is characterized by a centripetal dissolution leaving a small demineralized zone behind. In contrast, erosive demineralization in dentin is more complex as the acid-induced mineral dissolution leads to the exposure of collagenous organic matrix, which hampers ion diffusion and, thus, reduces further progression of the lesion. Topical fluoridation inducing the formation of a protective l...

    The erosion of bioerodible polymers depends on many factors including the polymer chain length, bond cleavage velocity, swellability, crystallinity, and water diffusivity in the polymer matrix. This multitude of parameters makes modeling of erosion difficult. Only a few models exist that describe morphological changes of polymers during erosion qualitatively. In the present approach the polymer matrix was represented as the sum of small individual polymer matrix parts. The factors that determ...

  16. Effects of estradiol on uterine perfusion in anesthetized cyclic mares affected with uterine vascular elastosis.

    Uterine vascular elastosis in mares is characterized by degeneration of uterine vasculature through thickening of the elastin layers. Factors commonly associated with this degeneration include age, parity, and chronic uterine endometritis. Affected mares have also been shown to exhibit decreases in uterine blood flow and perfusion of the uterus. Due to the increased thickness of the elastin layers, we hypothesize that vasodilatation of the uterine vasculature is also impaired. To test the functionality of these vessels, we evaluated the vasodilatory effects of estradiol on the uterine vascular bed in mares with normal vasculature and mares with severe elastosis. Both groups were tested in estrus and diestrus. Fluorescent microspheres were used to determine basal blood perfusion, followed by the intravenous administration of 1.0?g/kg of 17?-estradiol. After 90min, perfusion was measured once again to determine the vascular response to estradiol. Control mares in estrus displayed a significant increase in total uterine blood flow after the administration of estradiol when compared to baseline levels. No other group had a significant increase in total blood flow and perfusion after estradiol administration. The administration of estradiol in control mares induced regional increases in perfusion in the uterine horns and uterine body during estrus and only in the uterine horns during diestrus. Mares affected by elastosis exhibited no regional differences in perfusion levels post-estradiol administration. The difference in the vasodilatory response induced by estradiol between reproductively healthy mares and mares affected with elastosis indicates that the functionality of the affected vessels is compromised.

  17. Clinical application of uterine artery embolization in treating uterine scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To evaluate uterine artery embolization in treating uterine scar pregnancy. Methods: During the period from November 2007 to February 2010, 11 patients with uterine scar pregnancy were encountered in authors' hospital. All the patients had a history of lower uterine segment cesarean section. Four patients had to receive an emergency uterine artery embolization due to acute massive vaginal bleeding. The other 7 patients received intravenous chemotherapy with MTX (0.4 mg/kg/day, every 5 days as a treatment course). Emergency uterine artery embolization had to be carried out in three patients as they developed acute massive vaginal bleeding (blood loss ? 100 ml/hour) during the course of chemotherapy, while subsequent uterine artery embolization was performed in the remaining 4 patients after they had completed two courses of treatment when their blood HCG showed no significant decrease. The clinical results were analyzed. Results: Remarkable decrease in serum HCG was seen in all 11 patients after interventional management. The vaginal bleeding in 7 patients was significantly reduced within half an hour after uterine artery embolization. The uterus together with intact fertility was successfully preserved in all 11 patients. Conclusion: For the treatment of uterine scar pregnancy complicated by massive vaginal bleeding (blood loss ? 500 ml/24 h) and/or abnormal elevation of serum HCG (blood ?-HCG ? 20000 IU/L), ectopic pregnancy with the mass diameter ? 5 cm, uterine artery embolization treatment is very safe and effective. This technique can well preserve female patient's uterus and fertility ability. It is of value to employ this treatment in clinical practice. (authors)

  18. Impact of MRI in the management and staging of cancer of the uterine cervix

    International Nuclear Information System (INIS)

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

    Full Text Available Introduction: Uterine sarcomas are rare gynecological neoplasms and their classification is complicated. Uterine sarcoma is usually diagnosed in postmenopausal women and the diagnosis is often accidental and postoperative. Aim of this study was to present clinical and pathological characteristics of uterine sarcomas, diagnostic procedures, treatment and two-, three- and five-years cumulative survival rates. Materials and methods: The retrospective study of 61 cases of uterine sarcomas was conducted. Cases were distributed into groups based on definitive diagnosis of uterine sarcoma: group of leiomyosarcomas (LMS, carcinosarcoma (CS, endometrial stromal sarcomas (ESS, adenosarcomas (AS and other rare uterine sarcomas. We investigated patients with clinical and pathological characteristics of uterine sarcomas, diagnostic procedures and treatment. Survival rate was calculated by Kaplan-Meier method. Results: From 61 patients 43 patients (70.49% were postmenopausal. Mean period from menopause until appearance of symptoms was 14,63 years. One or more risk factors were present in 46 (75.4% patients. Diagnosis of uterine sarcoma were established averagely 7.38 months after appearance of symptoms. 50 patients (82.0% underwent one or more diagnostic procedures. Preoperative diagnosis of uterine sarcoma was established in 42.5% of patients. 53 (86.9% of patients were treated operatively. The most used operative procedure (60,7% was total hysterectomy with bilateral salpingooophorectomy. Postoperative pathohistologic analysis showed that low grade (LG leiomyosarcoma were present in 19 (35.9% cases, high grade (HG leiomyosarcoma in 1 (1.9% case, carcinosarcoma in 14 (26.4% cases, low grade (LG endometrial stromal sarcoma in 5 (9.4% cases, high grade (HG endometrial stromal sarcoma in 9 (17.0% cases, adenosarcoma in 2 (3.8% cases, and 2 cases of rare uterine sarcomas: 1 (1.9% MALT HG lymphoma and 1(1.9% malignant hemangiopericytoma. In one case of ESS (1.9% only adenomyosis was found postoperatively suggesting that the whole tumour was removed during diagnostic procedure. Eight patients were not treated operatively. Two-years cumulative survival rate was 74.3%, three-years cumulative survival rate was 71.1%, and five years survival rate was 64.3%. Discussion: Average age, percent of postmenopausal patients and the mean age at the time of menopause in our studied correlate with current data. Clinical presentation of uterine sarcoma is associated with obesity and hypertension in more than 30% of cases, which is approved in our study. For early diagnostics it is important to notice that risk factors are similar to those connected with far more frequent endometrial carcinoma. Postmenopausal abnormal bleeding was the main reason for medical examination, explaining relatively short period for establishing the diagnosis in this group of patients. The variety of clinical findings in our studied group showed that the diagnosis must be based on preoperative pathohistology. Conclusion: Adequate diagnosis and treatment of uterine sarcoma is possible with regular yearly or more frequent follow-up, especially in postmenopausal women with known risk factors present. We need special attention for unclear symptoms and postmenopausal bleeding and we need to use all diagnostic procedures soon as possible including preoperative histology because early metastases are characteristic for uterine sarcomas. Factor of the most important predictive value is histologic grade. .

    Bazer Fuller W

    2012-07-01

    Full Text Available Abstract There is a dialogue between the developing conceptus (embryo-fetus and associated placental membranes and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling, implantation, regulation of gene expression by uterine epithelial and stromal cells, placentation and exchange of nutrients and gases. The uterus provide a microenvironment in which molecules secreted by uterine epithelia or transported into the uterine lumen represent histotroph required for growth and development of the conceptus and receptivity of the uterus to implantation. Pregnancy recognition signaling mechanisms sustain the functional lifespan of the corpora lutea (CL which produce progesterone, the hormone of pregnancy essential for uterine functions that support implantation and placentation required for a successful outcome of pregnancy. It is within the peri-implantation period that most embryonic deaths occur due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. With proper placentation, the fetal fluids and fetal membranes each have unique functions to ensure hematotrophic and histotrophic nutrition in support of growth and development of the fetus. The endocrine status of the pregnant female and her nutritional status are critical for successful establishment and maintenance of pregnancy. This review addresses the complexity of key mechanisms that are characteristic of successful reproduction in sheep and pigs and gaps in knowledge that must be the subject of research in order to enhance fertility and reproductive health of livestock species.

  5. Uterine vascular lesions: a rare cause of abnormal uterine bleeding, reporting of two cases

    2014-06-01

    Full Text Available Uterine vascular lesions in the form of arteriovenous malformation or pseudo aneurysm are rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manner are essential because instrumentation that is often used for other causes of uterine bleeding can lead to massive hemorrhage. We describe two cases of uterine vascular malformation, one presenting as postabortal hemorrhage and other as postpartum hemorrhage. Case one presented as postabortal hemorrhage after induced abortion following dilatation and curettage. Case two presented as delayed postpartum hemorrhage after six weeks following cesarean section. In both cases diagnosis of uterine arteriovenous malformation was made on Doppler ultrasonography which was subsequently confirmed on pelvic angiography. The embolization of affected uterine arteries was performed successfully in both cases. Uterine vascular lesion should be suspected in patient with abnormal vaginal bleeding, especially who has recent medical history of induced abortion or dilatation and curettage or cesarean section and so on. Although angiography remains the gold standard for making diagnosis, Doppler ultrasonography is also a good noninvasive technique for the same. Uterine artery embolization offers a safe and effective treatment. [Int J Reprod Contracept Obstet Gynecol 2014; 3(3.000: 749-753

  6. Uterine arterial methotrexate infusion and embolization in the treatment of uterine adenomyosis

    International Nuclear Information System (INIS)

    Objective: To study the efficacy of treating different types of uterine adenomyosis with transcatheter local infusion of methotrexate (MTX) combined with uterine arterial embolization under guidance of digital subtraction angiography (DSA). Methods: 33 cases were primarily screened out according to clinical symptoms and color Doppler and then further diagnosis as diffuse or local adenomyosis were undertaken with super selective uterine arterial angiography. The patients were then treated with uterine arterial local infusion (50 mg MTX)and embolization with PVA microsphere (diameter 450-650 ?m), individually. Finally, the comparison between the preoperative and postoperative menstruation volumes, the degrees of dysmenorrheal, uterine sizes and the levels of sexual hormones of diffuse and local adenomyosis was carried out. Results: The uterine arterial local infusion of MTX combined with embolization showed no chemotherapeutic side effects. In all cases, there were decrease of menstruation amount, alleviated dysmenorrhea, reduction of uterine size, and the efficacy was more evident in diffuse adenomyosis (P<0.05). Conclusions: Micro-invasive interventional technique combined with drug therapy is promising for diffuse and local adenomyosis especially for the former. (authors)

    Full Text Available Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. Objective: This review discusses the role of salivary factors on the development of dental erosion. Material and Methods: A search was undertaken on MeDLINe website for papers from 1969 to 2010. The keywords used in the research were "saliva", "acquired pellicle", "salivary flow", "salivary buffering capacity" and "dental erosion". Inclusion of studies, data extraction and quality assessment were undertaken independently and in duplicate by two members of the review team. Disagreements were solved by discussion and consensus or by a third party. Results: Several characteristics and properties of saliva play an important role in dental erosion. Salivary clearance gradually eliminates the acids through swallowing and saliva presents buffering capacity causing neutralization and buffering of dietary acids. Salivary flow allows dilution of the acids. In addition, saliva is supersaturated with respect to tooth mineral, providing calcium, phosphate and fluoride necessary for remineralization after an erosive challenge. Furthermore, many proteins present in saliva and acquired pellicle play an important role in dental erosion. Conclusions: Saliva is the most important biological factor affecting the progression of dental erosion. Knowledge of its components and properties involved in this protective role can drive the development of preventive measures targeting to enhance its known beneficial effects.

Salivary flow allows dilution of the acids. In addition, saliva is supersaturated with respect to tooth mineral, providing calcium, phosphate and fluoride necessary for remineralization after an erosive challenge. Furthermore, many proteins present in saliva and acquired pellicle play an important role in dental erosion. Conclusions: Saliva is the most important biological factor affecting the progression of dental erosion. Knowledge of its components and properties involved in this protective role can drive the development of preventive measures targeting to enhance its known beneficial effects.

  9. Human papillomavirus types 16 and 18 in adenocarcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Many reports have shown a link between human papillomavirus (HPV) and cervical squamous neoplasia. However, the association of HPV with cervical adenocarcinoma has been studied less extensively. The authors evaluated the presence of HPV-DNA in 106 patients with adenocarcinoma of the uterine cervix by in situ hybridization, using 35S-labeled probes for HPV 16 DNA and HPV 18 DNA. The overall prevalence of HPV-DNA was 18% (19 of 106). HPV 16 was present in 2 (2%) cases, HPV 18 was observed in 15 (14%) cases, and both HPV 16 and HPV 18 were found in 2 (2%) cases. There was a correlation between HPV-DNA positivity and tumor stage (P less than 0.01) and tumor size (P less than 0.05), but there was no relationship between HPV-DNA positivity and tumor differentiation, proliferation (S-phase fraction), ploidy, lymph node metastases, or five-year survival rate. These results suggest that HPV 18 DNA is associated with cervical adenocarcinoma but the presence of HPV 18 has no influence on overall survival

    Cervical cancer (CC) is the third most common cancer in women worldwide; however, CC is a preventable disease, and much effort should be done to prevent it. Persistence of high-risk HPV infection is the strongest epidemiologic risk factor for CC, however it is not sufficient for development of the disease it cofactors should be present. In 2004; IARC listed cervical cancer among those causally related to smoking. Smoking interferes with incidence and prevalence of HPV infection and is associa...

    Death rates from cervical cancer have already fallen this century and for patients with invasive cervical cancer five year survival rates are greater than for most solid tumours. Better screening for premalignant changes may further reduce the incidence of invasive cancer; indeed, it has been claimed that the reduction in mortality could be as high as 90%, though estimates of screening efficacy have varied greatly. For those with advanced invasive carcinoma neoadjuvant chemotherapy may reduce...

    Full Text Available The investigation is dedicated to the study of the pathological alterations of cervical epithelium of uterus, proliferative activity in the lesion focuses and the improvement of cytological diagnosis of the state of cervical epithelium of uterus. The correlation between the proliferative processes in abnormal epithelium of uterine cervix and some pathological factors of the pregnant women organism was studied. The criteria for prognosis of the cervical epithelial dysplasia in pregnant women were elaborated on this basis of our data. The pathological processes in cervical epithelium were revealed in 309 pregnant women in the first trimester (mean age of women was 26,17±0,83 years. The hormonal state of pregnant women was studied on the basis of colpocytological picture and the colpocytological types which indicate the unfavorable prognosis with a certain degree of validity were determined. The mathematic model for all cytological groups of pregnant women for prognosis of inflammatory processes, epithelial dysplasia and preinvasive cervical cancer was created. The simple and comprehensible prognostic scheme for diagnosis of epithelial dysplasia and preinvasive cervical cancer was developed.

    Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this factor based on rainfall data with only low temporal resolution (daily, monthly, annual averages). The purpose of this study is to assess rainfall erosivity in Europe in the form of the RUSLE R-factor, based on the best available datasets. Data have been collected from 1541 precipitation stations in all European Union (EU) Member States and Switzerland, with temporal resolutions of 5 to 60 min. The R-factor values calculated from precipitation data of different temporal resolutions were normalised to R-factor values with temporal resolutions of 30 min using linear regression functions. Precipitation time series ranged from a minimum of 5 years to a maximum of 40 years. The average time series per precipitation station is around 17.1 years, the most datasets including the first decade of the 21st century. Gaussian Process Regression (GPR) has been used to interpolate the R-factor station values to a European rainfall erosivity map at 1 km resolution. The covariates used for the R-factor interpolation were climatic data (total precipitation, seasonal precipitation, precipitation of driest/wettest months, average temperature), elevation and latitude/longitude. The mean R-factor for the EU plus Switzerland is 722 MJ mm ha(-1) h(-1) yr(-1), with the highest values (>1000 MJ mm ha(-1) h(-1) yr(-1)) in the Mediterranean and alpine regions and the lowest (erosivity density (erosivity normalised to annual precipitation amounts) was also the highest in Mediterranean regions which implies high risk for erosive events and floods.

    We reviewed the autopsy records of 1872 cases of death because of politrauma, gunshot wounds and suicidal hanging. The analysis included causes and frequency of cervical spine fractures, their most common localisation, architecture of bone destruction and their influence on cervical cord. The most common cause of cervical spine injury was motor vehicle accidents. We examined 82 specimens with traumatic fractures of cervical spine obtained from accident victims. About half of the injuries occurred in upper cervical spine. The most common fracture localisation was C2 with dens fracture as the most frequent injury. The most common spinal cord lesion was complete rupture mainly at the upper cervical spine level. PMID:14564791

  15. A clinical index for evaluating and monitoring dental erosion

    DEFF Research Database (Denmark)

    Larsen, I B; Westergaard, J

    2000-01-01

    This study describes a new fine-scaled system for classifying initial and advanced dental erosions. The system includes the use of study casts of the teeth in an epoxy resin with an accurate surface reproduction. The severity of erosion on each tooth surface is scored according to six grades of severity. In addition, the presence of a Class V restoration and dental erosion on the same surface increases the erosion score, as it is assumed that the need for restorative treatment can be caused by the erosion. A high inter-examiner agreement was found when the present scoring system was used by two examiners on the same sample. With this prerequisite it is proposed that an index value for facial, oral, incisal/occlusal and cervical surfaces is calculated as the mean value of scores for the respective surfaces. The index values represent the severity of tooth substance loss in various locations of the oral cavity and are furthermore suitable for data analysis. The system is thereby well-suited for determining etiologic factors and monitoring the progression of erosion over time.

  16. Radiological appearances of degenerative uterine leiomyomas

    International Nuclear Information System (INIS)

    Uterine fibroids, also known as leiomyomas, are the most common uterine neoplasms. Although benign, they can be associated with significant morbidity and are the commonest indication for hysterectomy. They are often discovered incidentally when performing imaging for other reasons. Usually first identified with US, they can be further characterized with MRI. They are usually easily recognizable, but degenerate fibroids can have unusual appearances. Knowledge of the different appearances of fibroids on imaging is important as it enables prompt diagnosis and thereby guides treatment. (authors)

    2013-09-01

    Two types of the thermionic cathodes are used in industry: a) Tungsten (doped with thoria or pure) cathodes burning in a unreactive gas, and b) Thermo-chemical cathodes, such as a Hafnium cathode burning in oxygen plasma gas (mostly used plasma cutting). Both types of the cathodes experience cycle (arc on/off) erosion and constant current erosion. Available experimental data for both types of cathodes and both types of erosions (constant current and cycling) are presented and discussed. Based on the model the constant current erosion rate is calculated. Comparison of the results of the calculations with the experimental data show reasonable agreement. Existing hypotheses on cycling erosion are also discussed. For the Tungsten cathode, it is suggested that the start erosion is mainly due to the cold cathode mode (vacuum arc mode) of the arc operation that takes place just after the arc ignition. The presented estimation doesn't contradict this hypothesis. For the Hafnium cathode, the model of the ``open can'' erosion is supported by recently published observations.

    The etiology and pathophysiology of uterine leiomyomas, benign smooth muscle tumors of the uterus, are not well understood. To evaluate the role of mitochondria in uterine leiomyoma, we compared electron transport gene expressions of uterine leiomyoma tissue with myometrium tissue in six uterine leiomyoma patients by RT-PCR array. Our results showed an average of 1.562 (±0.445) fold increase in nuclear-encoded electron transport genes. These results might suggest an increase in size, number, or activity of mitochondria in uterine leiomyoma that, to our knowledge, has not been previously reported. PMID:25361934

    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 of HPV-associated cervical cancers from Japanese patients. The prevalence of MCPyV in these lesions was close to that observed in the cutaneous SCCs. Further worldwide epidemiological surveys are warranted to determine the possible association of MCPyV with pathogenesis of cervical cancers.

    Full Text Available Uterine leiomyoma (UL is common benign tumor of female genitals. Uterine artery embolization (UAE is widely used method of organ-sparing UL treatment. Safe ty of this procedure for future fertility and labor is controversial. We present a case of pregnancy in woman who previously underwent uterine artery embolization. During 12-months’ follow-up period patient periodically noted vaginal di¬scharge. No signs of UL have been found on ultrasound in 12 months of follow-up. Normal pregnancy occurred 1.5 years after UAE procedure which ended in normal labor without complications. Most authors report increased risk of pregnancy complications such as postpartum hemorrhage, preterm delivery, malpresentation after UAE. Our point of view is that a lot of pregnancy complications are possibly associated with persistence of necrotic leiomyoma tissue in uterine wall after UAE. Presented case allowed to draw preliminary conclusions that complete disappearance of UL nodule after UAE could improve pregnancy outcomes.

Abstract in english The measurement of cervical length utilizing transvaginal ultrasound is of help for pregnant women screening for premature labor, the shortening of the cervix being a predictor of higher risk of preterm delivery. Traditional methods for evaluating the uterine cervix during pregnancy are limited and [...] unsatisfactory. Digital examination of cervix, considered as the standard method, demonstrates large variation among different examiners; on the other hand, transvaginal sonography is an effective method of examination during pregnancy. Recently, three-dimensional ultrasound has been used in the clinical practice including the study of uterine cervix. The three-dimensional technology allows acquisition and storage of a large volume of data. Such stored information can be reformatted and analyzed through an unlimited number of planes. The three-dimensional transvaginal ultrasound is the unique imaging method capable of obtaining a true coronal plane by direct correlation of the views in a multiplanar display. This method seems to offer a diagnostic potential because of the cervical ultrasonography increased accuracy.

    Purpose: We have observed significant rates of uterine artery patency after uterine artery embolization (UAE) with nonspherical polyvinyl alcohol (nsPVA) on 6 month follow-up MR scanning. The study aim was to quantitatively assess uterine artery patency after UAE with nsPVA and to assess the effect of continued uterine artery patency on outcomes. Methods: A single centre, retrospective study of 50 patients undergoing bilateral UAE for uterine leiomyomata was undertaken. Pelvic MRI was performed before and 6 months after UAE. All embolizations were performed with nsPVA. Outcome measures included uterine artery patency, uterine and dominant fibroid volume, dominant fibroid percentage infarction, presence of ovarian arterial collaterals, and symptom scores assessed by the Uterine Fibroid Symptom and Quality of Life questionnaire (UFS-QOL). Results: Magnetic resonance angiographic evidence of uterine artery recanalization was demonstrated in 90 % of the patients (64 % bilateral, 26 % unilateral) at 6 months. Eighty percent of all dominant fibroids demonstrated >90 % infarction. The mean percentage reduction in dominant fibroid volume was 35 %. No significant difference was identified between nonpatent, unilateral, and bilateral recanalization of the uterine arteries with regard to percentage dominant fibroid infarction or dominant fibroid volume reduction. The presence of bilaterally or unilaterally patent uterine arteries was not associated with inferior clinical outcomes (symptom score or UFS-QOL scores) at 6 months. Conclusion: The high rates of uterine artery patency challenge the current paradigm that nsPVA is a permanent embolic agent and that permanent uterine artery occlusion is necessary to optimally treat uterine fibroids. Despite high rates of uterine artery recanalization in this cohort, satisfactory fibroid infarction rates and UFS-QOL scores were achieved.

    Uterine positional changes can reduce the accuracy of radiotherapy for cervical cancer patients. The purpose of this study was to; 1) Quantify the inter-fractional uterine displacement using a novel 3D ultrasound (US) imaging system, and 2) Compare the result with the bone match shift determined by Cone- Beam CT (CBCT) imaging.Five cervical cancer patients were enrolled in the study. Three of them underwent weekly CBCT imaging prior to treatment and bone match shift was applied. After treatment delivery they underwent a weekly US scan. The transabdominal scans were conducted using a Clarity US system (Clarity® Model 310C00). Uterine positional shifts based on soft-tissue match using US was performed and compared to bone match shifts for the three directions. Mean value (+/-1 SD) of the US shifts were (mm); anterior-posterior (A/P): (3.8+/-5.5), superior-inferior (S/I) (-3.5+/-5.2), and left-right (L/R): (0.4+/-4.9). The variations were larger than the CBCT shifts. The largest inter-fractional displacement was from -2 mm to +14 mm in the AP-direction for patient 3. Thus, CBCT bone matching underestimates the uterine positional displacement due to neglecting internal uterine positional change to the bone structures. Since the US images were significantly better than the CBCT images in terms of soft-tissue visualization, the US system can provide an optional image-guided radiation therapy (IGRT) system. US imaging might be a better IGRT system than CBCT, despite difficulty in capturing the entire uterus. Uterine shifts based on US imaging contains relative uterus-bone displacement, which is not taken into consideration using CBCT bone match.

  13. Computed tomographic evaluation of prognosis in advanced cervical cancer

    International Nuclear Information System (INIS)

    Forty-nine patients with primary cervical cancer were evaluated by Computed Tomography (CT) prior to irradiation or radical surgery. In 33 patients with stage III b cervical cancer, CT findings were compared with prognosis retrospectively. The cases were divided into two groups, one group showed recurrence within a year (14 cases, 42 %), the other group had no recurrent signs at 12 months (19 cases, 58 %). The findings demonstrated on CT and their ratios were as follows. 1) Parametrial mass. (71 % in recurrences, 21 % in non-recurrences) 2) Bladder involvement. (73 % in recurrences, 6 % in non-recurrences) 3) Low density in the uterine body. (93 % in recurrences, 47 % in non-recurrences) 4) Enlargement of the cervix. (93 % in recurrences, 74 % in non-recurrences) 5) Low density in the cervix. (57 % in recurrences, 42 % in non-recurrences) 6) Vaginal involvement. (45 % in recurrences, 42 % in non-recurrences) From the above mentioned findings, items 1), 2), and 3) showed significantly higher incidence in recurrent cases than in non-recurrent cases. The recurrence ratio of the cases that were positive for two or more of the items was 80 %. On the other hand, the recurrence ratio of the cases positive for one or less of the above categories was 11 %. The results showed that CT is effective in evaluating the prognosis of patients with advanced cervical cancer. (author)

    Uterine sarcomas are relatively rare mesenchymal malignant neoplasms with poor prognosis, accounting for 8%of all uterine malignant neoplasms. There are only a few moderately active cytotoxic agents for this entity, and therefore, chemotherapy for uterine sarcomas is palliative in most cases. According to traditional classification systems, uterine sarcomas encompass carcinosarcoma(CS), leiomyosarcoma(LMS), and endometrial stromal cell sarcoma(ESS). For carcinosarcoma, ifosfamide, cisplatin, and paclitaxel are reported to be moderately effective single agents. The combination of ifosfamide and cisplatin appeared to improve progression-free survival, but the severe toxicity it induced was not negligible. Paclitaxel and ifosfamide were the only chemotherapy regimen which slightly improved both progression-free and overall survival. For leiomyosarcoma and undifferentiated endometrial sarcoma(formerly named high-grade ESS), doxorubicin, ifosfamide, and gemcitabine are moderately effective single agents. There are several reports showing the effectiveness of gemcitabine plus docetaxel. For endometrial stromal sarcoma(formerly named low-grade ESS), progestins and aromatase inhibitors have been proven beneficial. PMID:22584323

    Endo-uterine resection is a true surgical act, well defined and atraumatic. To perform elective and complete one-stage hysteroscopic myomectomies, sparing normal myometrium, is not easy. Endometrial ablations provoking synaechie and adenomyosis should not be added to myomectomies. Complications of hysteroscopic surgery may be threatening and must be prevented. PMID:8875035

    Full Text Available Uterine neoplasms composed of an admixture of smooth muscle and adipose tissue are rare and have been designated as lipoleiomyomas. The origin of this tumor is stil controversial and it has not been sufficiently studied. The aim of our study was to investigate the immunohistochemical phenotype of fat cells in uterine lipoleiomyomas so as to clarify their origin. Archived tissue samples of 10 uterine lipoleiomyomas were selected and analyzed immunohistochemically for vimentin, desmin, and HMB-45 expression. The patients ranged from 31 to 63 years of age (mean age 53.5±9.9. Seven tumors which affected the uterine corpus, showed intramural location; while two cases were subserosal, and one was in the cervix. All tumors were constituted by irregular bundles of smooth cells and mature large adipose cells. The amount of adipose component varied from 5 to 95% of the tumor mass. Cytological atypia and necrosis were not seen. Immunohistochemical investigations revealed obvious reactivity to vimentin and desmin in perivascular immature mesencyhmal cells and tumoral smooth muscle cells. Adipose cells in the tumors demonstrated uniform vimentin expression and inconsistent desmin immunoreactivity. All adipose cells were negative for HMB-45 antigen. However, HMB-45 antigen was weakly positive in spindle shaped tumor cells of two cases. In our study, the immunohistochemical findings suggest a complex histogenesis for these tumors, which may arise from perivascular immature mesencyhmal cells or direct transformation of smooth muscle cells into adipocytes by means of progressive intracellular storage of lipids.

    Fallout isotopes can be used as artificial tracers of soil erosion and sediment accumulation. The most commonly used isotope to date has been 137Cs. Concentrations of 137Cs are, however, significantly lower in the Southern Hemisphere, and furthermore have now declined to 35% of original values due to radioactive decay. As a consequence the future utility of 137Cs is limited in Australia, with many erosion applications becoming untenable within the next 20 years, and there is a need to replace...

    Ectopic cervical deciduosis is generally an accidental finding during pregnancy, and usually presents without any symptoms or need for therapeutic intervention. However, it can sometimes imitate dysplasia or carcinoma. We report a case of a 34-year-old G2P0, with a history of cervical dysplasia, presenting at 11?weeks of gestation, with vaginal blood loss. During examination, lesions mimicking dysplasia were found on the cervix. Histological examination reported cervical deciduosis. Deciduosis is a benign change during pregnancy and will resolve spontaneously. With the increasing use of cytology and colposcopy, the reported incidence is growing. When it is hard to differentiate between dysplasia and deciduosis, histological confirmation should be considered. PMID:26396123

  20. Diffusion Weighted Imaging of the Uterus: Regional ADC Variation with Oral Contraceptive Usage and Comparison with Cervical Cancer

    International Nuclear Information System (INIS)

    Background: There is growing interest in diffusion weighted magnetic resonance imaging (MRI) of cervical carcinoma but normal uterine appearances and effects of the oral contraceptive pill (OCP) have not been described. Purpose: To establish apparent diffusion coefficient (ADC) values for normal regions of uterus, determine the effect of the OCP on these values, and compare them with ADCs from cervical cancer. Material and Methods: Twenty-seven premenopausal women (19 taking the OCP) with cervical intraepithelial neoplasia (CIN) were studied with T2W and diffusion weighted MRI (DW-MRI). Regions of interest were drawn on ADC maps by visual matching with T2W images on different zones of the uterus and values compared between women not taking and taking the OCp.A further group of 25 women with clinically obvious tumors of the cervix were also studied with T2W and DW-MRI and ADC values of tumor were compared with ADC values of cervical epithelium and stroma. Results: The ADC values of adjacent zones of the uterus and cervix were significantly different from one another (P<0.001). The junctional zone was seen as a band of restricted diffusion between endometrium and outer myometrium. The ADC value of the junctional zone of the uterus was significantly greater (P<0.001) in patients taking the OCP than those patients not taking the OCp.There was no significant affect of the OCP on the ADC values of other uterine zones. Conclusion: The zonal anatomy of the uterus is well demonstrated by DW-MRI with hormonal effects secondary to the OCP affecting junctional zone alone. ADC of cervical tumor is significantly different to cervical epithelium and stroma indicating a role in cervical cancer detection and local staging

    The proportion of vascular elements in relation to the parenchymal and stromal components was determined by morphometric analysis of the histologic preparations from biopsies of uterine cervix cancers. In all cases, the material was obtained from tumors in Stages Ib and IIa before any therapy was initiated. In the 23 cases in which radiation treatment of the lesions resulted in a survival longer than 5 years, the proportion of blood vessels in the neoplastic tissue was found to be larger, and especially the stromal components were richer in vascular elements than in the 22 cases in which survival was shorter than 5 years. It was concluded that vascular density at least in cervical cancers of the stages studied can be a diagnostic parameter of prognostic value as well as of therapeutic usefulness.

  2. Expression of ras oncogene and major histocompatibility complex (MHC) antigen in carcinomas of the uterine cervix

    International Nuclear Information System (INIS)

    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.

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    International Nuclear Information System (INIS)

    Rheumatoid cervical myelopathy was studied in 14 patients, clinically, radiographically and by computerized tomography with multiplanar reconstruction (CT/MPR). CT/MPR demonstrated significant unsuspected areas of compromise in 9 of the 14 patients, and altered the surgical procedure in 7 of these 9 patients. CT/MPR clearly identifies all levels of involvement including rotary subluxation. CT/MPR also allows assessment of the spinal nerve canal/foramen and the alignment of the foramina transversaria. CT/MPR is an essential addition to the evaluation of rheumatoid cervical myelopathy

    The mass screening for cervical cancer in the population of Miyagi Prefecture has covered the total 1,078,999 women by March 1981. Invasive cancer of the uterine cervix was discovered in 1032 women, carcinoma in situ in 829. 2) By methods of the examination, the institutional examination was on 72.5% of the examined in 1980. 3) With regards to the rates of examinees by age and the detection rate of the cancer of uterine cervix in 1980, the low detection rate in the age range of 30-50 years whose examination rate was over 20% compares against the high detection rate in the high age range, whose examination rate was low. 4) CAI in years 1965, 1970, 1975 and 1980 were 60.0, 116.7, 193.2 and 229.8 respectively. 5) The 302 cases of invasive cancer detected and treated before the end of 1974 were classified in clinical stages and investigated the results of treatment. The detection in Stage I was in 84.1%, this high percentage being a main factor to make the total treatment results of uterine cervical cancer pushed up to the high figure. PMID:6864010

    Full Text Available Abstract Background Uterine sarcomas are relatively rare tumors that account for approximately 1-3% of female genital tract malignancies and between 4-9% of uterine cancers. Less than 8% of all cases are Mullerian adenosarcoma, a distinctive uterine neoplasm characterized by a benign, but occasionally atypical, epithelial and a malignant, usually low-grade, stromal component, both of which should be integral and neoplastic constituents of the tumor. Mullerian adenosarcoma with sarcomatous overgrowth (MASO is a very aggressive variant, associated with post-operative recurrence, metastases, even when diagnosed in early stage. Case Presentation We present a fourth MASO case derived from uterine cervix in a 72-year-old woman with metrorrhagia and a polypoid mass protruding through the cervical ostium. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, systematic pelvic lymph node dissection, omental biopsy and appendectomy were performed. Surgery treatment was associated with adjuvant whole-pelvis radiation (45 Gy and adjuvant chemotherapy (cisplatin/ifosfamide. After nine months of follow up, the patient was free of tumor. Conclusions The rarity of MASO of the cervix involves a management difficult. Most authors recommend total abdominal hysterectomy, usually accompanied by bilateral salpingo-oophorectomy. There is no common agreement on staging by lymphadenectomy during primary surgery and adjuvant chemo-radio therapy.

  9. On fibrinolytic phenomenon in the cancerous tissue of cervical carcinoma with special reference to irradiation changes

    International Nuclear Information System (INIS)

    In a study undertaken to investigate alterations of fibrinolytic enzymes in cancerous tissue of the cervix under radiotherapy, specimens were taken from malignant tissues of cervical cancer patients during irradiation therapy with Linac x-ray at 1000, 2000 and 3000 rads and were subsequently assayed for fibrinolytic enzyme activities using the fibrin plate method. No plasmin activity was demonstrable in the normal mucosa of the uterine cervix. Cancerous tissue of the uterine cervix also showed no demonstrable plasmin activity. The malignant tissue, as compared to the normal mucosa of the cervix, was found to have a lower activator activity, a higher proactivator activity and lower activities of both antiplasmin inhibitors. During radiotherapy for cervical cancer, plasmin activity was demonstrable in the cancerous tissue and in patients with malignant neoplasm, demonstrating that plasmin activity increased as the radiation dose was increased. A relationship seemed to exist between morphological changes and alterations in the fibrinolytic system of cancerous tissue of the cervix. From these findings it seems that the altered fibrinolytic enzyme system in cancerous tissue may have a close relationship with the growth and development of malignancy and may also have an important role in the occurrence of metastasis. There were some cases, in which an abnormal increase in activator activity occurred during irradiation therapy, leading to the death of the patients. This fact points to the possibility that activator activity might provide a useful index for evaluating the prognosis of cervical cancer. (author)

  10. Rainfall Erosivity in Europe

    2015-01-01

    Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the Rfactor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this factor based on rainfall data with only low temporal resolution (daily, monthly, annual averages). The purpose of this study is to assess rainfall erosivity in Europe in the form of the RUSLE R-factor, based on the best available datasets. Data have been collected from 1541 precipitation stations in all European Union (EU) Member States and Switzerland, with temporal resolutions of 5 to 60 min. The R-factor values calculated from precipitation data of different temporal resolutions were normalised to R-factor values with temporal resolutions of 30 min using linear regression functions. Precipitation time series ranged from a minimum of 5 years to a maximum of 40 years. The average time series per precipitation station is around 17.1 years, the most datasets including the first decade of the 21st century. Gaussian Process Regression (GPR) has been used to interpolate the R-factor station values to a European rainfall erosivity map at 1 km resolution. The covariates used for the R-factor interpolation were climatic data (total precipitation, seasonal precipitation, precipitation of driest/wettest months, average temperature), elevation and latitude/longitude. The mean R-factor for the EU plus Switzerland is 722 MJ mm ha?1 h?1 yr?1, with the highest values (N1000 MJ mm ha?1 h?1 yr?1) in the Mediterranean and alpine regions and the lowest (b500 MJ mm ha?1 h?1 yr?1) in the Nordic countries.

  11. Studies on evaluation of staging of cancer of the uterine cervix by means of CT

    International Nuclear Information System (INIS)

    The present study was undertaken to evaluate the stage classification (FIGO) by using CT in 50 cases with cancer of the uterine cervix in which the final stage had been diagnosed. An accurate diagnosis was obtained in 6 of 14 Ib cases, 14 of 21 IIa cases, 5 of 6 IIb cases, 2 of 3 IIIa cases, 3 of 3 IIIb cases and 3 of 3 IVa cases, for a total of 33 of 50 (66 %). The diagnostic rate for Ib and IIa staging was 57 %, while that for IIb or more was 87 %, but the accuracy rate in IIIb and IVa was 100 %. As the equipment, a high resolutional GE 9800 CT using a special technique was employed. Employing special pretreatment for the patient, it became possible to accurately grasp the pelvic condition of the patients. CT evaluation was related to the extent of the cervical cancer and the presence of infiltration into the vaginal wall. According to a 4-stage classification of the CT image, the extent of infiltration to surrounding parametrium and the bladder was determined. As a result, the sensitivity for evaluating invasion into surrounding tissue raised 92 %, and it showed 100 % for cases with adhesion or invasion of the bladder. Therefore, CT can an extremely effective method to determine the clinical staging of cancer of the uterine cervix. (author)

    Full Text Available BACKGROUND: Sexually transmitted infections (STIs) caused by the Gram-negative bacteria Chlamydia trachomatis and Neisseria gonorrhoeae are associated with an increased risk of HIV acquisition in South African women. HIV infection involves binding of the virus to CD4+ receptors on host cells and sub [...] sequent binding to a chemokine co-receptor that mediates fusion with the host target cell membrane. OBJECTIVE: To investigate the potential impact of STIs on HIV receptor expression in cervical epithelial cells, and the molecular pathways mediating this effect. METHODS: Expression of Toll-like receptor 4 (TLR4), CD4+ and CCR5 was investigated in HPV type 18-positive (HeLa) and HPV-negative (C33A) cervical epithelial cells, uterine adenocarcinoma cells (Ishikawa), cervical squamous cell carcinoma tissue and normal cervical tissue by real-time polymerase chain reaction (RT-PCR) analysis. HIV receptor expression in HeLa cells was investigated in the presence/absence of 10 ?g/mL bacterial lipopolysaccharide (LPS) and chemical inhibitors of epidermal growth factor receptor (EGFR), extracellular signal-regulated kinase (ERK1/2) or cyclo-oxygenase-2 (COX-2) by RT-PCR analysis. RESULTS: TLR4, CD4+ and CCR5 expression was elevated in HeLa, C33A and Ishikawa cell lines and carcinoma tissue, compared with normal cervical tissue. Treatment of HeLa cells with LPS increased expression of the primary HIV chemokine co-receptor CCR5 (p

    Full Text Available Background: Mifepristone is potentially a method of inducing labour in late pregnancy by increasing uterine contractility and by increasing the sensitivity of the uterus to the actions of prostaglandins. Present study was done to portrait the beneficial of mifepristone induction of labour. The objective was to study the effect of mifepristone in induction of labour with the outcome of induction of labour (IOL. Methods: 100 patients (term were included, after their informed consent. Patients were categorized by BISHOP SCORE at the beginning of induction for comparison of BS, mode of delivery, induction delivery interval (IDI. Women undergoing induction with RU486 (200mg PO were grouped in one and those with placebo control group into another. Statistical analysis of categorical variables was done. Results: Rate of successful IOL or vaginal delivery was 76% in study group and only 36% in control group. After induction with mifepristone for cervical ripening in study group 76% patient who had cervical score 8 within 24 hours, whereas in control group 2% female’s cervical score was>8. Among the babies, 44% in the control group required baby unit admission as compared to 36% in the study group. Conclusions: In the present study, the women who were induced with mifepristone 200 mg per orally showed drastic improvement in cervical score within 24-48 hours and decreased the cesarean rate in the study group and amount of dose requirement of augmentation of labour with Misoprostol or Oxytocin, lesser NICU admission and maternal complication.

    The mechanical integrity of the uterine cervix is critical for a pregnancy to successfully reach full term. It must be strong to retain the fetus throughout gestation and then undergo a remodeling and softening process before labor for delivery of the fetus. It is believed that cervical insufficiency (CI), a condition in pregnancy resulting in preterm birth (PTB), is related to a cervix with compromised mechanical strength which cannot resist deformation caused by external forces generated by the growing fetus. Such PTBs are responsible for infant developmental problems and in severe cases infant mortality. To understand the etiologies of CI, our overall research goal is to investigate the mechanical behavior of the cervix. Permeability is a mechanical property of hydrated collagenous tissues that dictates the time-dependent response of the tissue to mechanical loading. The goal of this study was to design a novel soft tissue permeability testing device and to present direct hydraulic permeability measurements of excised nonpregnant (NP) and pregnant (PG) human cervical tissue from women with different obstetric histories. Results of hydraulic permeability testing indicate repeatability for specimens from single patients, with an order of magnitude separating the NP and PG group means (2.1?±?1.4×10(-14) and 3.2?±?4.8×10(-13)m(4)/N[middle dot]s, respectively), and large variability within the NP and PG sample groups. Differences were found between samples with similar obstetric histories, supporting the view that medical history may not be a good predictor of permeability (and therefore mechanical behavior) and highlighting the need for patient-specific measurements of cervical mechanical properties. The permeability measurements from this study will be used in future work to model the constitutive material behavior of cervical tissue and to develop in vivo diagnostic tools to stage the progression of labor.

  17. Current status, questions and challenges of transcatheter uterine artery embolization for the treatment of uterine fibroids

    International Nuclear Information System (INIS)

    Current status, questions and challenges of transcatheter uterine artery embolization (UAE) in the treatment of uterine fibroids were summarized and analysed. It has been proved that UAE presents a good effectiveness in controlling the symptoms and shrinkage of fibroid and uterine volumes during follow-up of 4 to 6.9 years domestically and abroad, but relapse of the fibroid may however occur in 2 years or longer after UAE. Generally speaking, UAE is safe in the treatment of uterine fibroids but has a possibility of serious complications. UAE has no damage on normal uterine tissues but may affect pregnancy and delivery of patients significantly later on the cause of hypoxia and inertia of uterus. UAE may cause amenorrhea in the minority of women with ovarian failure and endometrium atrophy. The current questions are how to improve long-term efficiency to reduce relapse of tumor and to insure the safety of UAE. It is our further task to exploit more new effective and safe embolic agents by using animal and clinical study on the basic knowledge of pathology, pharmacology, biochemistry, endocrinology and molecular biology.

    Introduction The sentinel node technique (S.N.) was proposed in cervical cancers in order to optimise the diagnosis of metastases and the lymphatic micrometastases in the early stages while avoiding useless wide clearings out. The identification of this node is done by injection of a dye and/or a radioactive colloid and its ablation for pathological examination. Patients and methods We report the case of three patients followed for a uterine cancer having benefited from a lymphoscintigraphy before surgery. During the surgical procedure, the detection of the sentinel node was carried out after cervical injection of blue dye and using a gamma detection probe. Results The lymphoscintigraphy was positive for two cases with a positive detection for the three cases during the operation. The pathological study revealed a node metastasis for one case. The technical of the sentinel node applied to uterine cancers appears realizable essentially for uterine cancers of early stage (I). However the risk of false negative can be observed in advanced cancer (III), as it is the case of our patient having a negative lymphoscintigraphy. Conclusion The nuclear medicine is important in the detection of the sentinel node of various cancers, uterine cancer included, thus allowing an appropriate cardiologic management. (authors)

  19. MRI of the uterus, uterine cervix, and vagina: diagnostic performance of dynamic contrast-enhanced fast multiplanar gradient-echo imaging in comparison with fast spin-echo T2-weighted pulse imaging

    International Nuclear Information System (INIS)

    The aim of this study was to compare the diagnostic performance of contrast-enhanced fast multiplanar gradient-echo (GRE) and T2-weighted fast spin-echo (FSE) image sets in the assessment of uterus, cervix, and vagina. Fast (up to 20 contiguous sections in 23 s) multiplanar GRE and FSE images of 45 patients referred for imaging of the female pelvis were evaluated retrospectively with regard to overall image quality and the ability to detect normal anatomic structures, as well as lesion conspicuity. Results were compared with histologic findings (n = 29) or clinical follow-up. Furthermore, a quantitative assessment of contrast-to-noise ratios among normal uterine and cervical structures as well as uterine lesions was performed for both sequences. On GRE images, uterine and cervical differentiation was best seen on the image sets acquired 15 and 60 s following contrast enhancement and results were significantly better compared with delayed images (p 2 test, the difference in diagnostic performance between FSE and GRE revealed no significant difference, whereas the combination of both techniques performed better than FSE imaging alone (p < 0.05). The presented data suggest that dynamic contrast-enhanced GRE imaging should be part of an MR examination of the female pelvis. Combined GRE and FSE imaging provide an excellent sensitivity in the assessment of uterine and vaginal pathologies. (orig.) (orig.)

    A carcinoid is defined as a tumor arising from endocrine cells with neurosecretory characteristics belonging to the APUD system. These cells are most frequently observed in the digestive tract and lungs. Uterine location is rare. This paper presents the case of a 21-year old patient with uterine carcinoid tumor. In order to establish the histopathologic diagnosis of the carcinoid tumor, we used optical microscopy examination in haematoxylin-eosin, argentic impregnation in Fontana-Masson staining and an immunohistochemical reaction using monoclonal antibody to the S100 protein. Due to the intracytoplasmatic granulations shown in Fontana-Masson staining and in the immunohistochemical reaction to S100 protein which confirm the neurosecretory character of the tumoral cells, we included this tumor in the group of tumors with neuroendocrine differentiation.

    Introduction. Most common metastasis sites of breast cancer are the lungs, bones, liver, and brain, whereas uterine involvement by metastatic breast disease is rare. Metastatic carcinoma of the uterus usually originates from other genital sites, most commonly being from the ovaries. Invasive lobular carcinoma spreads to gynecologic organs more frequently than invasive ductal carcinoma. Case Report. A 57-year-old postmenopausal woman was diagnosed with breast carcinoma 2 years ago and modified radical mastectomy was performed. Pathological examination of tumor revealed invasive ductal carcinoma, stage IIIc. She presented with abdominal pain and distension. Diagnostic workup and gynecologic examination revealed lesions that caused diffuse thickening of the uterus wall. Endometrial sampling was performed for confirmation of the diagnosis. She underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy. Breast carcinoma metastases in endometrium and myometrium were confirmed histopathologically and immunohistochemically. Conclusion. We herein report the first case of isolated uterine patient who had invasive ductal carcinoma of breast. PMID:23573438

    Since its recognition about 150 years ago, there has been much progress in the understanding of the pathogenesis, prevention, early detection and management of carcinoma of the uterine cervix. Important historical landmarks include the (1) recognition of pre-invasive and pre-clinical lesions, and the devise of various systems for reporting these lesions, (2) improvements in diagnostic techniques particularly colposcopy, (3) advent of therapeutic procedures (electrocoagulation, cryotherapy, laser therapy and loop electrosurgical excision), and (4) recognition of the aetiological relationship between the human papillomavirus and cervical neoplasia. The susceptibility of the cervical transformation zone to malignant change is now well recognised. The WHO classification system remains the one most commonly utilised for histological reporting of cervical cancers. In the recent 1994 update, cervical carcinoma is divided into 3 main categories: squamous cell carcinoma, adenocarcinoma and other epithelial tumours. Squamous cell carcinoma (60-80%) predominates among invasive cervical carcinoma. Recognised variants include verrucous, warty (condylomatous), papillary squamous (transitional) and lymphoepithelioma-like carcinoma. Adenocarcinoma (5-15% of invasive carcinomas) shows an increasing trend in young females. Like its squamous counterpart, preinvasive and microinvasive versions are known. Variants such as mucinous, endometrioid, clear cell, mesonephric, serous, villoglandular and minimal deviation carcinoma are now defined. Adenosquamous carcinoma (5-25%), adenoid-cystic, adenoid-basal, neuroendocrine and undifferentiated carcinomas constitute other epithelial tumours of the cervix. The management of invasive cervical carcinoma remains heavily dependent on its stage. The FIGO staging system remains the most widely used. The 1995 update provides more definite criteria in subdividing stage IA tumours by delimiting stromal invasion of stage IA1 lesions to a maximum depth of 3 mm and a horizontal axis of 7 mm. In Malaysia, an appreciation of the cervical carcinoma problem has to take into consideration the population at risk, its multi-ethnicity, its socio-economic and geographical diversities and the constraints of the health care system. Females form 48.9% of the Malaysian population. 52.9% of them are in the sexually active age group of 15-50 years, indicating a significant population at risk for cervical carcinoma. Cervical carcinoma was the third most common cause of death due to solid tumours among Malaysian females in 1995 following carcinoma of the breast and respiratory tract. East Malaysia is predominantly rural with many communities having limited modern facilities. Such areas imply a lower educational and socio-economic status, raising the worry of a population at higher risk for developing cervical carcinoma. The population: doctor for Malaysia of 2153:1 compares poorly with nearby Singapore. Besides a shortage of doctors, there is also an uneven distribution of doctors, resulting in a ratio in East Malaysia of > 4000:1. Although Malaysia does not have a national cervical cancer-screening programme, many action plans and cancer awareness campaigns have been launched throughout the years, which appear to have made an impact as evidenced by the decreasing mortality rates from cervical carcinoma. Another interesting feature of cervical carcinoma in Malaysia relates to its multiethnic population. In Malaysian Chinese and Malay females, the prevalence of cervical carcinoma ranks second to breast cancer whereas the pattern is reversed in Malaysian Indian females. Studies into its aetiology and pathogenesis are being undertaken and may shed more light on this matter. PMID:10879274

  9. Evaluation on the safety of transcatheter uterine artery embolization for uterine myoma

    International Nuclear Information System (INIS)

    Objective: To observe complications of transcatheter uterine artery embolization (TUAE) for uterine fibroids and to evaluate its long-term safety. Methods: One hundred and ninety-eight women with uterine fibroids were treated by TUAE. The bilateral TUAE were performed using lipiodol-pingyangmycineemulsion (LPE) and gelatin sponge particles in 186 women. Among them, 138 patients were followed up for 1 to 3 year and complications were observed. Results: Complications included ecchymosis and ulceration on buttock (n=1); ulcer of labia minora (n=1); urinary retention (n=12); urinary tract infection (n=1); expelling of necrotic fibroids via vagina (n=5); secondary infection of chocolate cyst of ovary (n=1); increasing in endometrial thickness and calcification (n=1) and amenorrhea (n=2). Conclusion: TUAE is a treatment with long-term safety, while severe complications or sequelae may occur to a few patients, so strict indication should be insisted in patient selection. (authors)

    2008-04-01

    Because of the increasing number of cicatricial uteruses, uterine ruptures are likely to become more frequent. However, few cases discovered in the postpartum period are described in literature. Our case report describes a uterine rupture, which occurred during a quick vaginal delivery, in a patient with previous cesarian section. The diagnosis has been made few days after delivery, the patient presenting pelvic pain and fever. We do not disagree with the principle to check uterine scar only when suspicion of rupture, but we should keep in mind that in case of endometritis in the postpartum period, with cicatricial uterus, it would be necessary to research uterine rupture by fitted imaging.

Selecionou-se declarações de óbito de residentes de Belém, de 1998-1999, com causa básica de morte neoplasia do [...] colo, corpo e porção não especificada do útero e aquelas que mencionavam essas neoplasias em qualquer linha do atestado, totalizando 188 declarações de óbito. Efetuou-se nova codificação para análise da confiabilidade, aferida pela concordância simples e pela estatística kappa. A causa básica do óbito, após revisão de prontuários médicos e/ou laudos histopatológicos, foi considerada como padrão-ouro para análise da validade de critério, através do valor preditivo positivo. Observou-se concordância simples de 94,0% e kappa de 0,87, sugerindo alta confiabilidade na codificação da causa básica câncer de útero no sistema oficial. Na análise da validade, confirmou-se 120 das 127 originais como colo de útero, três das quatro codificadas como corpo de útero e 18 das 48 classificadas como porção não especificada. Registrou-se aumento de 11,2 % nas neoplasias de colo uterino e redução de 62,5% nos óbitos de porção não especificada do útero. Abstract in english Belém, Pará State, Brazil, presents high mortality rates for uterine cervical cancer, thus justifying an analysis of the reliability and validity of data on this underlying cause of death. Death certificates for Belém residents who died in 1998-1999 from neoplasms of the uterine cervix, uterine body [...] , or unspecified uterine site, or with mention of such a neoplasm on any line in the death certificate, were selected, amounting to 188 death certificates (DCs). All DCs were submitted to new coding, and reliability analysis was performed by simple agreement and Cohen's kappa. The underlying cause of death, established after review of medical records and/or histopathological findings, was considered the gold standard for analysis of criteria validity, based on the positive predictive value. We observed a simple agreement of 94.0% and kappa of 0.87, suggesting high reliability of the official system's coding of uterine cancer as the underlying cause of death. In the validity analysis, 120 of the 127 deaths originally considered as caused by cancer of the uterine cervix and 3 of the 4 coded as cancer of the uterine body were confirmed. An 11.2% increase in uterine cervical tumors and a reduction of 62.5% in unspecified uterine tumors were observed.

    Full Text Available [...] Abstract in english The importance of inactivation of tumor suppressor genes in the development/progression of carcinomas of the uterine cervix is reviewed. It is well known that HPV-related oncogenes are strongly linked to cervical cancer.

Genetic deletions affecting tumor suppressor genes are the most common mechanism of inactivation of these genes. Studies using conventional molecular techniques such as restriction fragment length polymorphism (RFLP) and Southern Blot showed low frequency of deletions in cervical carcinomas. Detection of deletions by using RFLP and Southern Blot presents several disadvantages, the most important being the difficulty in analyzing pure tumor cells. More sensitive approaches include tissue microdissection and PCR analysis of microsatellites. Using these approaches, it has been shown that genetic deletions are, in fact, frequent events in cervical cancers, being detected in up to 95% of the cases. Multiple genetic loci are involved, including chromosomes 3p, 5p, 6p and 11q. Deletions are detected even in precursor lesions (cervical intraepithelial neoplasia, CIN). Some deletions have been correlated with prognostic parameters, such as stage, depth of invasion, and vascular space involvement. It is concluded that cervical carcinogenesis, like in other tumors, is a multistep process, characterized by the accumulation of events including activation of oncogenes, as well as inactivation of tumor suppressor genes.

    Full Text Available Ex utero intrapartum treatment (EXIT is a procedure performed during caesarean section with preservation of fetal-placental circulation, which allows the safe handling of fetal airways with risk of airways obstruction. This report aimed at describing a case of anaesthesia for EXIT in a fetus with cervical teratoma. A 30-year-old woman, 70 kg, 160 cm, gravida 2, para 1, was followed because of polyhydramniosis diagnosed at 24 weeks? gestation. During a routine ultrasonographic examination at 35 weeks? gestation, it was noticed that the fetus had a tumoral mass on the anterior neck, the mass had cystic and calcified components and with a size of was 10 x 6 x5 cm. The patient with physical status ASA I, was submitted to caesarean section under general anaesthesia with mechanically controlled ventilation for exutero intrapartum treatment (EXIT. Anaesthesia was induced in rapid sequence with fentanyl, propofol and rocuronium and was maintained with isoflurane in 2.5 at 3 % in O 2 and N 2 O (50%. After hysterotomy, fetus was partially released assuring uterus-placental circulation, followed by fetal laryngoscopy and tracheal intuba-tion. The infant was intubated with an uncuffed, size 2.5 endotracheal tube. Excision of the mass was performed under general anaesthesia. After surgical intervention, on the fourth postoperative day, the infant was extubated and the newborn was discharged to the pediatric neonatal unit and on the seventh day postoperatively to home without complications. Major recommendations for EXIT are maternal-fetal safety, uterine relaxation to maintain uterine volume and uterus-placental circulation, and fetal immobility to help airway handling. We report one case of cervical teratoma managed successfully with EXIT procedure.

  15. Methylation and silencing of the retinoic acid receptor-?2 gene in cervical cancer

    International Nuclear Information System (INIS)

    Expression of the retinoic acid receptor ?2 (RAR-?2), a putative tumor suppressor gene, is reduced in various human cancers, including squamous cell carcinomas (SCC) of the uterine cervix. The mechanism of the inhibition of RAR-?2 expression remains obscure. We examined whether methylation of RAR-?2 gene could be responsible for this silencing in cervical SCC. Expression of RAR-?2 mRNA and methylation status of the 5' region of RAR-?2 gene were examined in 20 matched specimens from patients with cervical SCC and in three cervical cancer cell lines by Northern blot analysis and methylation-specific PCR (MSP) assay or Southern blot analysis respectively. In 8 out 20 cervical SCC (40%) the levels of RAR-?2 mRNA were decreased or undetectable in comparison with non-neoplastic cervix tissues. All 8 tumors with reduced levels of RAR-?2 mRNA expression showed methylation of the promoter and the first exon expressed in the RAR-?2 transcript. The RAR-?2 gene from non-neoplastic cervical tissues was mostly unmethylated and expressed, but methylated alleles of the gene were found in three samples of the morphologically normal tissues adjacent to the tumors. Three cervical cancer cell lines with extremely low level of RAR-?2 mRNA expression, SiHA, HeLA and CaSki, also showed methylation of this region of the RAR-?2 gene. These findings suggest that methylation of the 5' region of RAR-?2 gene may contribute to gene silencing and that methylation of this region may be an important and early event in cervical carcinogenesis. These findings may be useful to make retinoids more effective as preventive and therapeutic agents in combination with inhibitors of DNA methylation

  16. The application of uterine artery embolization for the treatment of uterine scar pregnancy after cesarean section

    International Nuclear Information System (INIS)

    Objective: To assess the clinical value of uterine arterial embolization (UAE) in treating uterine scar pregnancy after cesarean section. Methods: A total of' 35 cases with cesarean scar pregnancy, admitted to authors' hospital during the period from Jan. 2007 to June 2011, were divided into two groups: embolization group (n=21) and non-embolization group (n=14). By using Seldinger technique, UAE was performed via the right femoral access and gelatin sponge particle was used as embolization agent to occlude the uterine artery. In embolization group, sixteen patients received uterine cavity curettage one or two days after UAE, while five patients received laparotomy or perineotomy surgery to remove the lesions after UAE. In non-embolization group, uterine cavity curettage was performed directly in 8 patients, local injection of' methotrexate followed by uterine cavity curettage was carried out in 3 patients, and direct laparotomy to remove the lesions was adopted in the remaining 3 patients. The blood loss during the procedure, the hospitalization days and the time for ?-HCG levels falling to normal were documented. The results were compared between the two groups. Results: UAE was successfully accomplished in all the 21 patients of embolization group and the uterus was preserved in all patients. For the embolization group, the mean hospitalization time was (11.5±3.6) days, and the time for ?-HCG levels falling to normal was (18.6±4.9) days. For the non-embolization group, the mean hospitalization time was(20.4±5.2)days, and the time for ?-HCG levels falling to normal was (28.7±5.6)days. Hysterectomy had to be carried out in two patients of non-embolization group due to the massive bleeding occurred in therapeutic procedures. Conclusion: For the treatment of cesarean scar pregnancy, UAE is very effective and mini-invasive with high success rate. UAE can preserve the patient's reproductive function, and it also plays a significant role in preventing hemorrhage and assisting hemostasis. (authors)

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.

    ABSTRACT: Human papillomavirus (HPV) infection, and in particularly infection with HPVs 16 and 18, is a central carcinogenic factor in the uterine cervix. We established and optimized a PCR assay for the detection and discrimination of HPV types 16 and 18 in archival formaldehyde fixed and paraffin embedded (FFPE) sections of cervical cancer.Tissue blocks from 35 cases of in situ or invasive cervical squamous cell carcinoma and surrogate FFPE sections containing the cell lines HeLa and SiHa were...

    Assessing the impact of glaciation on Earth's surface requires understanding glacial erosion processes. Developing erosion theories is challenging because of the complex nature of the erosion processes and the difficulty of examining the ice/bedrock interface of contemporary glaciers. We demonstrate that the glacial erosion rate is proportional to the ice-sliding velocity squared, by quantifying spatial variations in ice-sliding velocity and the erosion rate of a fast-flowing Alpine glacier. The nonlinear behavior implies a high erosion sensitivity to small variations in topographic slope and precipitation. A nonlinear rate law suggests that abrasion may dominate over other erosion processes in fast-flowing glaciers. It may also explain the wide range of observed glacial erosion rates and, in part, the impact of glaciation on mountainous landscapes during the past few million years. PMID:26450208

  5. Uterine segmentation and volume measurement in uterine fibroid patients' MRI using fuzzy C-mean algorithm and morphological operations

    International Nuclear Information System (INIS)

    Uterine fibroids are common benign tumors of the female pelvis. Uterine artery embolization is an effective treatment of symptomatic uterine fibroids by shrinkage of the size of these tumors. Segmentation of the uterine region is essential for an accurate treatment strategy. Objectives: In this paper, we will introduce a new method for uterine segmentation in T1W and enhanced T1W magnetic resonance images in a group of fibroid patients candidated for UAE in order to make a reliable tool for uterine volumetry. Patients and Methods: Uterine was initially segmented using Fuzzy C-Mean method in T1W-enhanced images and some morphological operations were then applied to refine the initial segmentation. Finally redundant parts were removed by masking the segmented region in T1W-enhanced image over the registered TlW image and using histogram thresholding. This method was evaluated using a dataset with ten patients' images (sagittal, axial and coronal views). Results: We compared manually segmented images with the output of our system and obtained a mean similarity of 80percent, mean sensitivity of 75.32percentand a mean specificity of 89.5percent. The Pearson correlation coefficient between the areas measured by the manual method and the automated method was 0.99. Conclusions: The quantitative results illustrate good performance of this method. By uterine segmentation, fibroids in the uterine may be segmented and their properties may be analyzed.
