Cervical myomectomy with uterine artery ligation at its origin.  

Science.gov (United States)

This study was performed to examine the feasibility, blood loss, duration of surgery, and complications in patients with cervical myomas in whom the uterine artery was ligated before myomectomy. Laparoscopic cervical myomectomy was performed in 12 women with cervical myomas and menorrhagia. The uterine artery was ligated at its origin from the internal iliac as an initial step to reduce the blood loss. Myomectomy was subsequently performed, and the myomas were enucleated by incising the capsule anteriorly or posteriorly depending on their location. Hysterectomy was not necessary in any patient. Even large cervical myomas were removed with minimal blood loss. Laparoscopic cervical myomectomy is a minimally invasive and technically safe procedure. PMID:19835802

Study on radiosensitivity of uterine cervical cancer  

International Nuclear Information System (INIS)

Radiosensitivity of uterine cervical cancer was discussed. As a test irradiation, a total of 1000 rad of Tele Cobalt was given in 500 rad doses for two days running. Radiosensitivity was judged before and seven days after test irradiation. As methods of radiosensitivity judgement, the following methods were used: I) physiological and biochemical examination (oxygen partial pressure, measurement of the amount of DNA in nucleus, labelling rate with 3H-thymidine, and measurement of uptake rate of 32P and II) morphological examination (histological discussion and cytodiagnosis). Method I was not definite in all cases as examination methods of radiosensitivity, and there were many problems in technique. In method II, histological examination was more suitable for clinical application. The possibility of radiosensitivity deduction was also discussed from histological figures before irradiation.

Early stage cervical cancer of the uterine  

International Nuclear Information System (INIS)

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

Reliability of transrectal ultrasonography in diagnosis of uterine cervical carcinoma  

International Nuclear Information System (INIS)

To evaluate the reliability of transrectal ultrasonography (TRUS) to define adult female genital organ and to diagnose and stage the cervical carcinomas. After analysis of normal ultrasonographic anatomy of female pelvis in ten healthy women, I performed TRUS in thirty patients of uterine cervical carcinomas by rotating the 5 MHz electronic linear array transducer(SL2, Siemens, Erlangen, Germany) along the reference sagittal plane in the middle of uterine cervix and vagina. The results of TRUS were analyzed and compared to FIGO, surgical pathology, CT and MRT, ect. TRUS allowed good visualization of the uterus, uterine cervix, parametrium, vagina, anterior rectal wall, walls of the urinary bladder, and uterine cervical carcinomas. The accuracy of staging with TRUS was 83%, compared with the accuracy of 67% for clinical staging according to the criteria of the international Federation of Gynecology and Obstetrics(FIGO). For extent of parametrial involvement, the sensitivity of TRUS was 93%, with the specificity of 86% and the diagnostic accuracy of 89%. The same reliability parameters for clinical evaluation were 71%, 79% and 75% respectively. Above findings suggest that low-cost TRUS could be usefully applied to pretreatment evaluation of patients with uterine cervical carcinoma

DNA fragmentation following chemotherapy and radiotherapy for uterine cervical carcinoma  

Energy Technology Data Exchange (ETDEWEB)

The present study evaluated the effects of chemotherapy and radiotherapy in uterine cervical carcinoma cells using to measure DNA fragmentation as an indicator of apoptosis. We studied 11 Japanese women with uterine cervical carcinoma (aged 38 to 64 years), in which 6 patients consented to receive an injection of CBDCA (carboplatin) (150 mg) into the uterine artery during radical hysterectomy with pelvic lymphadenectomy and 5 others received radiotherapy. The DNA fragmentation was measured using the nick end-labeling method of paraffin sections from formalin fixed tissues obtained by biopsy before and after the hysterectomy. DNA fragmentation specific for apoptosis was found in tissue sections after the intraarterial injection of CBDCA as well as radiotherapy. The positive nuclei before and after injection of CBDCA was 2.37{+-}0.89% and 6.49{+-}1.79%, respectively. The number of positive nuclei after treatment varied between patients. The positive nuclei observed in 5 patients received radiotherapy was 4.95{+-}2.24% before radiotherapy, 13.85{+-}5.79% after 10 Gy, 10.59{+-}5.51% after 30 Gy and 1.37{+-}1.04% after 50 Gy. The highest proportion of positive nuclei was seen at doses of 10 Gy and 30 Gy. Apoptosis was thought to be the principal cause of the cell death resulting from chemotherapy and radiotherapy in uterine cervical carcinoma, and to be induced several hours after the intra-arterial injection of CBDCA or during radiotherapy with low doses.

Uterine cervical cancer. Preoperative staging with magnetic resonance imaging  

International Nuclear Information System (INIS)

The treatment of uterine cervical carcinoma is largely dependent on the tumor stage. Despite significant inaccuracies in the clinical examination, uterine cervical cancer remains the only gynecological form of cancer still largely staged according to clinical findings. Although imaging is still not included in the staging the recently published revised FIGO (Federation International de Gynecologie et d'Obstetrique) system encourages the use of modern cross-sectional imaging (magnetic resonance imaging MRI and computed tomography CT). Due to its high soft tissue contrast MRI allows excellent non-invasive assessment of the cervix with direct tumor delineation as well as assessment of the prognosis based on morphological factors. Studies in the literature report an accuracy of 93% for MRI in the preoperative assessment of tumor size and in the differentiation of operable from advanced cervical cancer. Therefore MRI is considered to be the optimal modality for diagnostic evaluation starting from FIGO stage IB1, for radiation therapy planning, and for exclusion of recurrence in follow-up. In this paper we give an overview of the role of magnetic resonance imaging in preoperative staging of uterine cervical cancer. (orig.)

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.

Superselective intraarterial chemotherapy into bilateral uterine arteries in uterine cervical carcinomas  

Energy Technology Data Exchange (ETDEWEB)

To assess the efficacy of superselective intra-arterial chemotherapy(SSIAC) via the bilateral uterine arteries in cases of cervical carcinoma. Eighteen patients with stage 2 {sub a}(n=10), 2 {sub b}(n=7), or 3 {sub a}(n=1) cervical carcinoma underwent one(n=2) or two(n=16) courses of preoperative SSIAC with Vincristine, Cisplatin, and Mitomycin C. We estimated the extent of reduction of tumor volume and improvement of stage, comparing pre-SSIAC MRI to postoperative results. Tumor vascularity, as seen on uterine arteriography, and procedural complications, were also evaluated. A marked reduction in tumor volume was observed in all patients, an average reduction volume of 94.7%. Improvement of stage was noted in 16 patients, and in six of these, no residual viable tumor or microinvasive residual tumor was seen. On angiography, tumor hypervascularity was demonstrated in seven patients, but its degree was not substantially related to therapeutic response. In no case did significant systemic complications of result from chemotherapy; in one patient, however, we experienced a serious complication of necrotizing cystitis due to malpositioning of a catheter in the superior vesical artery. SSIAC via the bilateral uterine arteries is an effective complementary modality for the treatment of various stages of cervical carcinoma.

Short-course palliative radiotherapy for uterine cervical cancer  

International Nuclear Information System (INIS)

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.

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)

Current advancement in radiation therapy for uterine cervical cancer  

International Nuclear Information System (INIS)

Radiation therapy is one of the effective curative treatments for uterine cervical cancer. However poor clinical results for the advanced stages require further improvement of the treatment. Intensive studies on basic and clinical research have been made to improve local control, primarily important for long term survival in radiation therapy. Regarding current advancement in radiation therapy for uterine cervical cancer, the following three major subjects are pointed out; technological development to improve dose distribution by image guided radiation therapy technology, the concomitant anticancer chemotherapy with combination of radiation therapy, and radiation biological assessment of the radiation resistance of tumors. The biological factors overviewed in this article include hypoxia relating factors of hypoxia-inducible factor (HIF)-1?, superoxide dismutase (SOD), cell cycle parameters of pMI, proliferation factors of Ki67, epidermal growth factor receptor (EGFR), cerbB2, cyclo-oxygenase (COX)-2, cycle regulation proteins p53, p21, apoptosis regulation proteins Bcl2 and Bax and so on. Especially, the variety of these radiation biological factors is important for the selection of an effective treatment method for each patient to maximize the treatment benefit. (author)

What is better: cryocautery or electrocautery for cervical erosion?  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Present study was conducted with a background in mind to compare the efficacy of electrocautery and cryocautery for the management of cervical erosion. Aim of this study was to compare the efficacy of electrocautery and cryocautery for the treatment of cervical erosion and to check cost effectiveness. Methods: A comparative study was conducted at Maharishi Markandeshwar medical college and hospital, Kumarhatti (Solan between July'13 to June'14 among 100 patients of reproductive age group with cervical erosion. They were grouped into 2 groups A (Electrocautery and B (Cryocautery and data obtained was analysed by paired t-test. Results: Though in short- term follow-up at 4-6 weeks after cautery, apparently electrocautery was superior to cryocautery in terms of erosion healing rate 92% vs. 76% as P value (0.4557 is not statistically significant, but in long-term follow-up at 12-14 weeks there was no significant difference in erosion healing but electrocautery was cost effective. Conclusions: Both types of cautery were equally good for treatment of cervical erosion in long-term follow-up. But electrocautery occupies less space and there is no chance of gas leakage in electrocautery, so electrocautery is more cost effective.

The role of ultrasound in the assessment of uterine cervical cancer.  

Science.gov (United States)

Uterine cervical cancer is the second most frequent gynecological malignancy worldwide. The assessment of the extent of disease is essential for planning optimal treatment. Imaging techniques are increasingly used in the pre-treatment work-up of cervical cancer. Currently, MRI for local extent of disease evaluation and PET-scan for distant disease assessment are considered as first-line techniques. Notwithstanding, in the last few years, ultrasound has gained attention as an imaging technique for evaluating women with cervical cancer. In this paper, current knowledge about the use of ultrasound for assessing uterine cervical cancer will be reviewed and discussed. PMID:25368452

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

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 pa42 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

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.

Radiotherapy and B-M therapy in uterine cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

In patients with advanced cancer of uterine cervix, combined modality treatment is proven to produce favorable results, but the best sequence or fractionation of chemotherapy is unknown. Thirty four patients with advanced squamous cell carcinoma of the cervix were treated with combinations of radiotherapy and B-M therapy at the Department of Radiology, Tokushima University Hospital from 1979 to 1991. The standard radiation therapy for these patients was essentially based on the combination of intracavitary brachytherapy and external pelvis irradiation. B-M therapy (Bleomycin 5 mg intramuscularly daily 7 days and the next eighth day Mitomycin-C 10 mg intravenously) was employed 1-4 cycles combined with irradiation. The 5-year survival rates were 75.0% in Stage II{sub b}, 71.4% in Stage III{sub b}, 60.0% in Stage IV{sub a} and 50.0% in whole patients. Bleomycin pulmonary toxicity occurred in two patients in this study. These results suggest that this combinations therapy may be an attractive option in the treatment of advanced cervical cancer.

High-dose-rate brachytherapy in uterine cervical carcinoma  

International Nuclear Information System (INIS)

Purpose: High-dose-rate (HDR) brachytherapy is in wide use for curative treatment of cervical cancer. The American Brachytherapy Society has recommended that the individual fraction size be <7.5 Gy and the range of fractions should be four to eight; however, many fractionation schedules, varying from institution to institution, are in use. We use 9 Gy/fraction of HDR in two to five fractions in patients with carcinoma of the uterine cervix. We found that our results and toxicity were comparable to those reported in the literature and hereby present our experience with this fractionation schedule. Methods and Materials: A total of 121 patients with Stage I-III carcinoma of the uterine cervix were treated with HDR brachytherapy between 1996 and 2000. The total number of patients analyzed was 113. The median patient age was 53 years, and the histopathologic type was squamous cell carcinoma in 93% of patients. The patients were subdivided into Groups 1 and 2. In Group 1, 18 patients with Stage Ib-IIb disease, tumor size <4 cm, and preserved cervical anatomy underwent simultaneous external beam radiotherapy to the pelvis to a dose of 40 Gy in 20 fractions within 4 weeks with central shielding and HDR brachytherapy of 9 Gy/fraction, given weekly, and interdigitated with external beam radiotherapy. The 95 patients in Group 2, who had Stage IIb-IIIb disease underwent external beam radiotherapy to the pelvis to a dose of 46 Gy in 23 fractions within 4.5 weeks followed by two sactions within 4.5 weeks followed by two sessions of HDR intracavitary brachytherapy of 9 Gy each given 1 week apart. The follow-up range was 3-7 years (median, 36.4 months). Late toxicity was graded according to the Radiation Therapy Oncology Group criteria. Results: The 5-year actuarial local control and disease-free survival rate was 74.5% and 62.0%, respectively. The actuarial local control rate at 5 years was 100% for Stage I, 80% for Stage II, and 67.2% for Stage III patients. The 5-year actuarial disease-free survival rate was 88.8% for Stage I, 76.52% for Stage II, and 50.4% for Stage III patients. Local failure occurred in 2 (11.1%) of the 18 Group 1 patients and in 20 (21.0%) of the 95 Group 2 patients. Distant failure occurred in none of the Group 1 patients and in 8 (8.4%) of the 95 Group 2 patients. None of the patients developed Grade 3 rectal toxicity. Grade 3 bladder toxicity was observed in 2 patients. The actuarial risk of Grade 3 or worse late toxicity was 3.31%. Conclusion: The results of our study indicate that HDR brachytherapy at 9 Gy/fraction is both safe and effective in the management of carcinoma of the cervix, with good local control and a minimum of normal tissue toxicity

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 fa 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.

Therapeutic Results of Postoperative Radiation Therapy for Uterine Cervical Cancer  

International Nuclear Information System (INIS)

This is a retrospective analysis of 64 patients who was treated with postoperative radiation therapy after radical hysterectomy and bilateral pelvic lymphadenectomy (53 patients) or total abdominal hysterectomy(11 patients) for uterine cervix cancer between May 1980 and September 1991 at the Department of Radiation Oncology, Kyung Hee University Hospital. Most patients were FIGO IB (31 patients) and IIA (25 patients), and median period of follow-up was 5.1 years. Of these patients, 24 received adjuvant whole pelvis irradiation of 6000 cGy and 40 received 5000-5500 cGy whole pelvis irradiation and/or intracavitary radiation (7 patients). The actuarial overall and relapse free 5 year survival rate were 71.0%, 68.3% respectively. The survival rates by stage were 79.1% in stage I, and 61.2% in stage II. Treatment failure was noted in 18 of 64 patients (28.1%), locoregional failure in 8(12.5%), distant metastasis in 8(12.5%), paraaortic node metastasis in 1 and one patient had concurrent locoregional and distant metastasis. The univariate analysis of prognostic factors affecting to overall survival rate represented lymph node status, the number and site of metastatic lymph node, parametrial invasion, the thickness of cervical wall invasion, and size of cancer mass. Histology, vessel invasion, endometrial extension, hemoglobin level, resection margin status, age, radiation dose were not significant prognostic factors. Complication relating to operation and postoperative radelating to operation and postoperative radiation were variable according to radiation therapy method: 6000 cGy RT group 8/24(33.3%), 5000-5500 cGy+ICR 3/7(42.9%), 5000-5500 cGy external RT only group 3/33(9.1%). In conclusion, the results suggest that postoperative radiotherapy is necessary in high risk patients for locoregional control and improving survival rate, and higher dose not improve results but only increases complication

Staging of uterine cervical cancer with MRI: guidelines of the European Society of Urogenital Radiology  

International Nuclear Information System (INIS)

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.)

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)

Variable uterine uptake of FDG in adenomyosis during concurrent chemoradiation therapy for cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

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.

Utility of the broccoli sign in the distinction of prolapsed uterine tumor from cervical tumor  

Energy Technology Data Exchange (ETDEWEB)

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.

Diagnosis of recurrent uterine cervical cancer: computed tomography versus positron emission tomography  

International Nuclear Information System (INIS)

To determine the accuracy of CT and positron emission tomography (PET) in the diagnosis of recurrent uterine cervical cancer. Imaging findings of CT and PET in 36 patients (mean age, 53 years) in whom recurrent uterine cervical cancer was suspected were analyzed retrospectively. Between October 1997 and May 1998, they had undergone surgery and/or radiation therapy. Tumor recurrence was confirmed by pathologic examination or follow-up studies. In detecting recurrent uterine cervical cancer, the sensitivity, specificity, and accuracy of CT were 77.8%, 83.3%, and 80.5%, respectively, while for PET, the corresponding figures were 100%, 94.4%, and 97.2%. The Chi-square test revealed no significant difference in specificity (p= .2888), but significant differences in sensitivity (p= .0339) and accuracy (p= .0244). PET proved to be a reliable screening method for detecting recurrent uterine cervical cancer, but to determine the anatomical localization of recurrent tumors, and thus decide an adequate treatment plan, CT was eventually needed

Metastatic Breast Cancer to the Uterine Cervix Mimicking a Giant Cervical Leiomyoma  

Directory of Open Access Journals (Sweden)

Full Text Available Metastasis to the uterine cervix is a complication of breast cancer that is not commonly known. Detection of cervical metastasis before the diagnosis of the primary tumor is even rarer. The present report describes a case of a 52-year-old woman who had a large cervical tumor appearing as a leiomyoma. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. Histopathological examination of the cervical tumor showed patterns characteristic of invasive lobular carcinoma of the breast, leading to the discovery of the primary in the left breast. She subsequently underwent mastectomy, hormone therapy and chemotherapy, and is alive at 7-year follow-up.

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)

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.

International Nuclear Information System (INIS)

Purpose : To evaluate 5-year survival rate, patterns of failure and complications of cervical cancer treatment, fifty nine patients treated by curative cancer were analyzed retrospectively. Methods and Materials : From March 1986 to May 1990, fifty nine patients with histologically proven uterine cervical cancer were analyzed. According to FIGO stage, there were 2 patients (3.4%) in stage Ib, 2 patients (3.4%) in stage IIa, 31 patients (52.5%) in stage IIb, 15 patients (25.4%) in stage IIIb, 9 patients (15.3%) in stage IV, External RT was per formed by 6 MVLINAC with daily 1.8 Gy, 5 times per week and followed by ICR, A point dose of ICR was calculated to 30-43.66 Gy (median : 34.6Gy). These techniques delivered total A point dose of 80.4 to 109.8 Gy (median : 85Gy). Patients had been followed up from 2 to 110 months (median : 61 months). Results : The overall 5-year survival rate and disease free survival rate were 55.9% and 55.0 % respectively. According to FIGO stage, the 5-year survival rate for less than Iia, IIb, IIIb, IV were 75.0%, 74.8%, 26.7%, 33.3%, respectively. In univariate analysis, the 5-year survival rate for stage IIb and below versus stage llla and above revealed 74.8%, 29.2% respectively (p<0.005). According to FIGO stage, the 5-year survival rate for less than lla, llb, lllb, IV were 75.0%, 74.8%, 26.7%, 33.3%, respectively. In univariate analysis, the 5-year survival rate for stage llb and below versus stage llla and above revealed 74.8%, 29.2% rage llla and above revealed 74.8%, 29.2% respectively (p<0.005). According to the hemoglobin level during RT, the 5-year survival rate of was 73.3% for patients with Hg 10 gm/dL or higher, in contrast to 0% for those with lower than 10 gm/dL (p<0.005). In 18 patients with nonbulky tumor (<5 cm), the 5-year survival rates were 71.8%. The 5-year survival rates for 18 patients with 5 cm or greater in tumor diameter were 22.2% (p<0.005). The 5-year survival rate for patient age of above 50 years and below were 65.3%, 34.2% respectively (p<0.05). ECOG performance status, pathologic finding, total dose, total treatment time were not statistically significant factors. The significant prognostic factors affecting overall 5-year survival rate by multicariate analysis showed the hemoglobin level during RT (p=0.0001), tumor size (p=0.0390), FIGO stage (p=0.0468). Total recurrence rate was 23.7%; local failure 15.2% (9/59), distant metastasis 6.8% (4/59), local and distant metastasis 1.7% (1/59). According to the RTOG/EORTC Soma Scales, the late complication rate was 23.8% (14/59). The late complication rate of colorectum and genitourinary tract were 15.3% (9/59), 8.5% (5/59), respectively : 10 patients(17.0%) were grade 2, 3 patients (5.1%) were grade 3 and one patient (1.7%) (1/59). According to the RTOG/EORTC Soma Scales, the late complication rate was 23.8% (14/59). The late complication rate of colorectum and genitourinary tract were 15.3% (9/59), 8.5% (5/59), respectively : 10 patients (17.0%) were grade 2,3 patients (5.1%) were grade 3 and one patient(1.7%) was grade 4. The late complications were radiation proctitis, rectal bleedint, radiation colitis, diarrhea and radiation cystitis in decreasing order. Conclusion : For improvement of therapeutic results, prospective randomized trials are recommended to discover new prognostic factors and more aggressive radiation therapeutic methods are needed for poor prognostic patients. The adjuvant chemotherapy or radiation-sensitizing agents must be considered to inhibit regional and distant metastasis

Prediction of prognosis using pretreatment FDG PET in uterine cervical carcinoma  

International Nuclear Information System (INIS)

In uterine cervical cancer, it is clinically important to predict prognosis on initial staging. We investigated whether abnormally increased FDG uptake of lymph nodes and peak SUV of primary tumor on initial FDG PET can predict prognosis after treatment in cervical patients. Subjects were 74 newly diagnosed cervical cancer patients (50±12yr). Whole body PET was performed after an injection of F-18 FDG. Peak SUV was measured in the primary cervical tumor. Images were interpreted by two nuclear medicine physicians. Follow-up for the disease-free survival was done in all patients. Survival analysis was done by using the Kaplan-Meier method, and a Logrank test was used to compare survival. Cox regression analysis was followed to find independent predictive factors. Recurrence occurred in 13 patients. In univariate analysis, advanced FIGO stage, large size of primary tumor, positive lymph node on MRI of CT, and positive lymph node on PET were significant prognostic factors to predict recurrence. Peak SUV and cell type of tumor failed to show any significant correlation with disease-free survival. In multivariate analysis, positive lymph node on PET (Exp(?)=6.416, p=0.002) and on CT or MRI (Exp(?)=5.711, p=0.026) were independent prognostic factors for predicting recurrence. In uterine cervical cancer, lymph node metastasis of pretreatment FDG PET is the best independent prognostic factor for predicting recurrence. But, peak SUV was not significant prognostic factor not significant prognostic factor

Metalloproteinase activities of a disintegrin and metalloproteinase 17 (ADAM17), amphiregulin (AREG), extracellular matrix metalloproteinase inducer (EMMPRIN), and matrix metalloproteinases (MMPs) are involved in tumor biology. In patients with uterine cervical carcinoma, the expression and prognostic significance of ADAM17 remain to be fully elucidated. The expression of ADAM17, AREG, EMMPRIN, phospho-epidermal growth factor receptor (p-EGFR), phospho-extracellular signal-regulated kinase (p-ERK), MMP-2, and MMP-9 was assessed by immunohistochemistry and/or Western blotting from cervical carcinoma cell lines, SiHa and HeLa cells, and cervical carcinoma tissues. AREG activity was measured by ELISA assay. The correlation of ADAM17, AREG, EMMPRIN, and MMP-9 expression with patients' survival rates was assessed by Kaplan-Meier and Cox regression analyses. RNA interference (RNAi) experiment was performed using small interfering mRNA to ADAM17 and EMMPRIN. ADAM17, EMMPRIN, and MMP-9 protein content was overexpressed in cervical carcinoma tissues compared with normal cervical tissues (P?SiHa and HeLa cells. ELISA assay revealed that AREG activity was stimulated by ADAM17 and was reversed by ADAM17 RNAi in SiHa and HeLa cells. Our data suggest that the increased expression of ADAM17 in cervical cancer is significantly associated with aggressive progression and poor prognosis. ADAM17 may be a molecular marker for predicting the progression and prognosis in cervical cancer. PMID:24793016

Clinical significance of magnetic resonance imaging (MRI) in evaluation of the extension of uterine cervical cancer  

International Nuclear Information System (INIS)

Magnetic resonance imaging (MRI) was performed in 62 patients with uterine cervical cancer and the preoperative MRI findings were compared with the pathological findings following surgery. The surgical stages of 62 patients were 2 at stage 0, 18 at stage Ia, 19 at stage Ib, 9 at stage IIa, 11 at stage IIb, 2 at stage IIIa, and 1 at stage IIIb. The MRI findings in the present study included: (1) the existence of a high intensity area (HIA) in the uterine cervix or minimum thickness of residual normal cervical tissue, (2) necrotic cavity, (3) pyometra, (4) irregular margin of the cervix, (5) parametrial invasion, (6) vaginal invasion, (7) bladder invasion, and (8) lymph node enlargement. No HIA was observed in any patient with stage 0 or stage Ia, in 8 patients with stage Ib, and in 2 patients with stage IIa, while all patients with cancer tissues greater than 10 mm in diameter had a HIA. In 39 patients in whom hysterectomy was undergone without conization, the findings of MRI correlated significantly (r=0.929, p<0.001) with the minimum thickness of residual normal cervical tissue by the pathological measurement. When the irregular margin of the cervix was regarded as a disruption of the cervical myo-metrium by cancer tissue, accuracy was 87%. Furthermore, the degrees of accuracy for parametrial invasion, vaginal invasion and bladder invasion were 92%, 90% and 94%, respectively. When lymphnodes greater than 15 mm in diameter were regarded as a positive in MRI, accuracy e regarded as a positive in MRI, accuracy was 88%. The present results indicate that MRI is clinically effective in preoperatively evaluating the extension of uterine cervical cancer. (author)

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-ptoms 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.

Incidence and clinicopathologic behavior of uterine cervical carcinoma in renal transplant recipients  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Renal allograft recipients are reported to have a higher incidence of malignancy than the general population. This single hospital-based study examined the incidence and clinicopathologic behavior of uterine cervical carcinoma in renal transplant recipients. Methods Among 453 women receiving renal transplantation from January 1990 to December 2008, 5 patients were diagnosed with cervical carcinoma. Medical records of these 5 patients were retrospectively reviewed, and clinicopathologic data were collected and analyzed. Results The incidence of cervical carcinoma in renal transplant recipients was 58.1 out of 100,000 per year, which is 3.5 times higher than in the general Korean population. The mean interval between the time of renal transplantation and the time of cervical carcinoma diagnosis was 80.7 months. After a median follow-up of 96.2 months, there was no recurrence of the disease or death. In 4 patients who were positive from human papillomavirus in situ hybridization (HPV ISH, high or probably high risk HPV DNA was detected in all. Punctate staining of HPV ISH was detected in 3 out of 4 patients. Conclusions Higher incidence of cervical carcinoma is expected in renal transplant recipients, so appropriate surveillance is needed to ensure early detection and treatment of cervical carcinoma.

Apparent diffusion coefficient in cervical cancer of the uterus: comparison with the normal uterine cervix  

Energy Technology Data Exchange (ETDEWEB)

A relation between apparent diffusion coefficient (ADC) values and tumor cellular density has been reported. The purpose of this study was to measure the ADC values of cervical cancers in the uterus and compare them with those of normal cervical tissues, and to test whether ADC could differentiate between normal and malignant cervical tissues in the uterus. Twelve consecutive female patients with cervical cancer of the uterus and ten female patients with other pelvic abnormalities were included in this study. ADC was measured at 1.5 T with b-factors of 0, 300 and 600 s/mm{sup 2} using single-shot echo-planar diffusion-weighted imaging and a parallel imaging technique. The mean ADC value of cervical cancer lesions was 1.09{+-}0.20 x 10{sup -3} mm{sup 2}/s, and that of normal cervix tissue was 1.79{+-}0.24 x 10{sup -3} mm{sup 2}/s (P<0.0001). In nine patients treated by chemotherapy and/or radiation therapy, the mean ADC value of the cervical cancer lesion increased significantly after therapy (P<0.001). The present study showed, with a small number of patients, that ADC measurement has a potential ability to differentiate between normal and cancerous tissue in the uterine cervix. Further study is necessary to determine the accuracy of ADC measurement in monitoring the treatment response. (orig.)

Sirtuin1 expression predicts the efficacy of neoadjuvant chemotherapy for locally advanced uterine cervical cancer.  

Science.gov (United States)

Cisplatin-based, cyclic balloon-occluded arterial infusion, neoadjuvant chemotherapy (NAC) has previously been reported to enable hysterectomy in patients with locally advanced cervical cancer. Sirtuin1 (SIRT1) is a nicotinamide adenine dinucleotide (NAD(+))-dependent histone deacetylase that deacetylates a number of proteins and is overexpressed in several human malignancies. Upregulation of SIRT1 has been reported to induce tumorigenesis and chemoresistance. To assess the role of SIRT1 in uterine cervical cancer, the outcomes in 62 patients aged FIGO) stage IIIA-IIIB uterine cervical cancer were reviewed between 1995 and 2010. Tumor samples were obtained by biopsy prior to NAC. The patients were separated into two groups. One group comprised of the patients in which NAC was effective, surgery and radiotherapy were performed (NAC+OP+R group; n=35), and the second group contained patients in which NAC was ineffective and radiation therapy was performed (NAC+R group; n=27). SIRT1 and p53 expression was assessed immunohistochemically in paraffin-embedded sections. SIRT1 expression was significantly higher in the NAC+R compared to the NAC+OP+R group (P<0.001), as was p53 expression (P=0.001). The overall survival time was significantly longer in the NAC+OP+R compared to the NAC+R group (P=0.001). Following the division of patients into two groups based on SIRT1 level, low (weighted score ?4, n=30), and high level (weighted score ?6, n=32) groups, the former group was significantly more sensitive to NAC (P<0.001). Collectively, these results indicate that SIRT1 expression may predict the efficacy of NAC as a treatment for locally advanced uterine cervical cancer. PMID:25469273

Cell biologic properties in explant culture and heterotransplantation of malignant uterine cervical cells.  

Science.gov (United States)

The cell of origin of uterine cervical cancer was studied by using culture, enzyme histochemistry and heterotransplantation. Twenty-seven epidermoid carcinomas (8 large cell keratinizing squamous, 12 large cell nonkeratinizing squamous and 7 small cell nonkeratinizing squamous) and 2 adenocarcinomas of the uterine cervix were placed in culture. An outgrowth of carcinoma cells in vitro was observed in 22 of 29 cases: 6 keratinizing, 8 large cell nonkeratinizing and 6 small cell nonkeratinizing carcinomas and 2 adenocarcinomas. The squamous carcinomas showed a squamous-cell outgrowth pattern, except for one large cell nonkeratinizing and three small cell nonkeratinizing carcinomas that showed a glandular-cell outgrowth pattern. One of three keratinizing carcinomas was transplantable into the subcutis of BALB/c nude mice, producing keratinizing tumors; three of six large cell and one of three small cell nonkeratinizing carcinomas reproduced themselves, while the other two small cell carcinomas produced poorly differentiated adenocarcinomas in mice. The transplanted adenocarcinoma produced a well-differentiated adenocarcinoma resembling the original tumor. Small cell carcinomas and adenocarcinomas contained a heat-stable, L-phenylalanine-sensitive alkaline phosphatase. These results suggest that many uterine cervical cancers originate from the reserve cell. PMID:3425154

Diagnostic values and limits of x-ray computed tomography in untreated uterine cervical cancer  

International Nuclear Information System (INIS)

Seventy patients with untreated uterine cervical cancer were prospectively evaluated by X-ray computed tomography (X-CT). Diagnoses were confirmed after radical hysterectomy for 44 cases, and by staging laparotomy for 26 cases. Paraaortic lymph node biopsies were performed for all patients. The results obtained were as follows: 1) X-CT was of little value in detecting pelvic lymph node metastasis. In comparison with pathological findings obtained from pelvic lymph node dissection, only 26 % of pelvic lymph node metastases were detected by X-CT. About 40 % of the lymph nodes with metastases, even if relatively large, were missed by X-CT. 2) X-CT was useful in detecting paraaortic lymph node metastasis. Its diagnostic accuracy equalled that of the clinical judgment of surgeons. X-CT could detect the lymph nodes which were 1 cm in diameter or larger. 3) X-CT was inferior to manual pelvic examinations under anesthesia for the diagnosis of parametrial involvement. 4) X-CT measurements of the vital tumor size at the uterine cervix correlated well with inspection of surgical specimens. Barrel-shaped tumors were easily detected by X-CT. 5) Excretory urography was not necessary when X-CT had been performed. The role of X-CT in clinical staging of uterine cervical cancer is also discussed. (author)

Pelvic insufficiency fracture after definitive radiotherapy for uterine cervical cancer: retrospective analysis of risk factors  

Science.gov (United States)

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. PMID:23685668

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)

Tumor cell kinetics in uterine cervical carcinoma following irradiation  

International Nuclear Information System (INIS)

15 cases of squamous cell carcinoma of uterine cervix which received radiotherapy were investigated in order to elucidate tumor cell kinetics following irradiation. The DNA content of Pararosanillin-Feulgen stained tumor cells were measured by fluorescence cytophotometry which provided great precision in the field of microspectrophotometry. Besides the cell preparation, tumor cells were precisely identified under blue light excitation (405nm). It is of great value to obtain a reliable DNA histogram of tumor cells with this method. In both groups of radioresistant cases (n=3) and radiosensitive cases (n=12), the same trend in cell kinetics was noted until 1400 rad, such as G2-block, endoreduplication, and a decrease in the 2C cell (G0 + G1) population. Most of the residual cells at 3000 rad of radioresistant cases showed little irradiation-induced morphological change. These cells were proved to be 2C cells in this study. This indicates that these radioresistant cells were non-cycling cells (G0). The mean value for the 2C cell population before irradiation was 65% in radioresistant cases and 46% in radiosensitive cases, respectively. The former contained a larger proportion of 2C cells than the latter. Clinically, the 2C cell population before irradiation may be used as a useful parameter to forecast radiosensitivity. (author)

Undetectable, small uterine cervical tumors on MR imaging : comparison to detectable tumors  

International Nuclear Information System (INIS)

Small uterine cervical tumors are often undetected on MRI, and undetectable tumors are usually regarded as being in their early stages. The purpose of this study was to evaluate morphological factors determining MRI detectability of uterine cervical tumors by comparing detected and undetected tumors using high resolution MRI units. Sixty-six surgically proven uterine cervical cancer patients were included in this study. Using GE Signa 1.5T magnet (GE, USA), axial T1-weighted MR images and axial, sagittal, and coronal T2-weighted fast spin echo MR images were obtained with a 5 mm thickness/2 mm gap and a 512x256 matrix size. The patients were divided into two groups, tumor-detected and tumor-undetected. Maximal tumor dimension, depth of stromal invasion, and horizontal tumor spread, measured during histopathological examinations, as well as pathological stages, were compared between the two groups. In the tumor-detected group, the pathological stages were IB1 in 25, IB2 in 3, IIA in 10, and IIB in 5 patients; in the tumor-undetected group, the stages were IA1 in 8, IA2 in 2, and IB1 in 13 patients. Maximal tumor dimension, depth of stromal invasion, and horizontal tumor spread for tumor-detected and -undetected groups were 27.4(10-60)mm vs. 10.4(3-40)mm (p=0.077), 11.1 (3-20)mm vs. 2.3(0-5)mm (p<0.001), and 26.6(8-60)mm vs. 10.4(3-40)mm (p=0.057), respectively. Of the criteria studied, depth of stromal invasion is the most important factor in determining tumor detectabrtant factor in determining tumor detectability on MRI. All tumors in which this depth was more than 5mm were thus detected;those which are undetected on high resolution MRI can be regarded as early-stage tumors (stage IB1)

Usefulness of tumor size on MR imaging in assessing the prognosis of uterine cervical cancer treated with radiation  

International Nuclear Information System (INIS)

The purpose of this study was to assess the usefulness of MR imaging (MRI) in evaluating the primary tumor and predicting the prognosis after radiotherapy for uterine cervical carcinoma. MRI was performed before radiotherapy in 25 patients with squamous cell carcinoma. According to the staging of FIGO, 3 patients were classified as stage Ib, 1 as IIa, 5 as IIb, 13 as IIIb, 2 as IVa, and 1 as IVb. Three-dimensional diameters (transverse, anteroposterior, and craniocaudal) of the primary tumor were evaluated on T2-weighted images. For patients with tumors ?4 cm in craniocaudal diameter, i.e., the length of the tumor parallel to the long axis of uterine body, five-year disease-free survival (DFS) was 70%. For patients with tumors >4 cm in craniocaudal diameter, the 5-year DFS was 37%. The difference between the two groups was statistically significant. For patients with tumors ?4 cm and >4 cm in transverse or anteroposterior diameter, 5-year DFS was 63% and 50% respectively. There was no statistically significant difference between the two groups. The results showed the craniocaudal diameter of the tumor to be the most critical factor in predicting prognosis after radiation therapy in uterine cervical cancer. Moreover, MRI was an important means of evaluating the depth of uterine cervical carcinoma. In conclusion, MRI is useful in evaluating the effect of radiotherapy and predicting prognosis in uterine cervical cancer. (author)

Results of Radiotherapy for the Uterine Cervical Cancer  

International Nuclear Information System (INIS)

One hundred fifty-four patients with the carcinoma of the uterine cervix were studied retrospectively to assess the result and impact of treatment at Department of Radiation Oncology, Korea University, Hae-Wha Hospital from Feb 1981 through Dec. 1986. Prior to radiotherapy, the patients were evaluated and staged by recommendation of FIGO including physical examination, pelvic examination, cystoscopy, rectosigmoidoscopy, chest X-ray, IVP, Ba enema. Also, an additional pelvic CT scan was obtained for some of the patients. The patients were treated by radiotherapy alone or adjuvant postoperative irradiation; In case of radiation therapy only, whole pelvic irradiation was given with C0-69 teletherapy unit via AP and PA parallel opposing fields or 4-oblique fields, 180 cGy per day, 5 days per week and intracavitary insertion was performed. Three dimensional quantitative demonstration of tumor volume is also important in planning radiation therapy. Another advantage of CT scan was detection of recurrent tumor after radiation or surgery. Local control rate of tumor according to the size was 91.3% for less than 5 cm in size and 44.6% in tumor over 5 cm (p<0.0068). Thirty out of 50 recurrent sites has locoregional failures and 17 cases has distant metastases. And the papa-aortic lymph nodes were the most common site for distant metastases. The most common complication was temporal rectal bleeding which was controlled most by conservative management. However, 4 patients requireve management. However, 4 patients required for endoscopic cauterization. The 5-year survival rates showed; stage la and lb 95%, stage lla 81% stage llb 67%, stage llla 37.7%, stage lllb 23%, and 3-year survival rate of stage lVa showed 11.6%, retrospectively

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.)

Effect of subclinical uterine infection on cervical and uterine involution, estrous activity and fertility in postpartum buffaloes.  

Science.gov (United States)

Nili-Ravi buffaloes (n=29) that calved normally between August and November and did not develop any clinical reproductive disorder after calving were studied for the incidence of sub-clinical bacterial infection of the uterus and its effects on postpartum reproductive efficiency. The incidence of subclinical uterine infection was 24% (7/29). Involution of the cervix and uterus was slower (P buffaloes of the two groups. However, the rate of involution of the cervix and the gravid horn was lower in buffaloes of the infected group (2.2 vs. 2.7 mm/day and 2.6 vs. 3.2 mm/day). The mean interval to first post partum ovulation was similar in buffaloes in the infected (35.5 days) and the normal group (33.8 days). The life span of corpus luteum formed after first ovulation was shorter (11 days) in buffaloes of both groups than that of a normal estrous cycle (15 to 17 days). The incidence of silent ovulation was apparently higher in buffaloes of the infected group (83 vs. 60%) but the difference was not significant. For the first four months after calving, the mean interval to first postpartum estrus was longer in buffaloes of the infected group (73.0 vs. 47.7 days; P buffaloes of the infected group (91.0 vs. 64.8 days; P buffaloes of the two groups. We conclude that subclinical bacterial infection of the postpartum uterus delays the cervical and uterine involution which can, in turn, delay the occurrence of first postpartum estrus and prolong the service period in buffaloes.

Clinical Significance of CENP-H Expression in Uterine Cervical Cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Objective This work aims to investigate the expression pattern and clinicopathologic significance of centromere protein H (CENP-H in uterine cervical cancer (UCC.Methods 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.Results 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.Conclusions 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.

Bacterial vaginosis is associated with uterine cervical human papillomavirus infection: a meta-analysis  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Bacterial vaginosis (BV, an alteration of vaginal flora involving a decrease in Lactobacilli and predominance of anaerobic bacteria, is among the most common cause of vaginal complaints for women of childbearing age. It is well known that BV has an influence in acquisition of certain genital infections. However, association between BV and cervical human papillomavirus (HPV infection has been inconsistent among studies. The objective of this meta-analysis of published studies is to clarify and summarize published literature on the extent to which BV is associated with cervical HPV infection. Methods Medline and Web of Science were systematically searched for eligible publications until December 2009. Articles were selected based on inclusion and exclusion criteria. After testing heterogeneity of studies, meta-analysis was performed using random effect model. Results Twelve eligible studies were selected to review the association between BV and HPV, including a total of 6,372 women. The pooled prevalence of BV was 32%. The overall estimated odds ratio (OR showed a positive association between BV and cervical HPV infection (OR, 1.43; 95% confidence interval, 1.11-1.84. Conclusion This meta-analysis of available literature resulted in a positive association between BV and uterine cervical HPV infection.

Effect of strong Posterisan ointment on rectal injuries after radiotherapy of uterine cervical cancer  

International Nuclear Information System (INIS)

In order to reduce the rectal injuries in the patients that received telecobalt irradiation after radical operation of uterine cervical cancer, strong posterisan ointment was employed. The ointment, composed of 0.16259 ml of death E. coli suspension, 2.5 mg of hydrocortisone and 4.98 mg of phenol per 1 gram, was given in 2 grams at one dose 2 to 3 time a day for 2 to 35 days according to severity of the symptoms. 60Co irradiation was performed in 150 to 200 rads 5 times a week. A total dose reached 4000 to 6000 rads, and the most patients were given 5000 rads. Of 9 patients, in whom the drug was given before and simultaneously with the onset of radiotherapy, irradiation was completed in 3 patients without any symptoms during radiotherapy. It suggested that the drug had a preventive effect on rectal injuries. Of 47 patients, in whom some symptoms were observed, the drug was effective in 30 patients, slightly effective in 8 and ineffective in 9, with the effective rate of 80.9 per cents. It was revealed that the drug was effective to the treatment of rectal injuries in radiotherapy of uterine cervical cancer. (Kumagai, S.)

The treatment of Uterine Cervical Cancer Using High Dose Rate Co-60 Sources  

International Nuclear Information System (INIS)

The radical treatment of uterine cervical cancer by intracavitary radium or cesium, in combination with teletherapy are well known. Although the result of such treatment should not give rise to complacency, problem of radiation exposure to medical staff had not been resolved. Fortunately, many attempts have been made to reduce this hazard, most of which take the form of afterloading applicators with a suitably shielded radioisotope. In order to avoid hazardous radiation exposure to staffs concerned with brachytherapy, RALS using high intensity source of Co-60, have been employed at Yonsei Cancer Center since May, 1979. It allows rectal and bladder doses to be kept low, while maintaining a satisfactory usual dose distribution of the other type of applicators, and the short treatment time allow four or five patients to be treated per hour. It also removes much patient's discomfort and the difficulties of nursing these patients. Since the first introduction in Korea, over seven hundred cases with various stage of uterine cervical cancer have been treated on a radical basis at this center last 4 years. These authors have strongly attracted attention to the results in terms of local control rate, survival s and morbidity compared with those of conventional low dose rate radiotherapy. Retrospective interim analysis of data was preliminarily accomplished through the labored follow-up study of 340 cases treated during initial 2 years and the radiobiological standpoint of highand the radiobiological standpoint of high dose rate intracavitary irradiation will be discussed

Nomogram Prediction of Overall Survival After Curative Irradiation for Uterine Cervical Cancer  

International Nuclear Information System (INIS)

Purpose: The purpose of this study was to develop a nomogram capable of predicting the probability of 5-year survival after radical radiotherapy (RT) without chemotherapy for uterine cervical cancer. Methods and Materials: We retrospectively analyzed 549 patients that underwent radical RT for uterine cervical cancer between March 1994 and April 2002 at our institution. Multivariate analysis using Cox proportional hazards regression was performed and this Cox model was used as the basis for the devised nomogram. The model was internally validated for discrimination and calibration by bootstrap resampling. Results: By multivariate regression analysis, the model showed that age, hemoglobin level before RT, Federation Internationale de Gynecologie Obstetrique (FIGO) stage, maximal tumor diameter, lymph node status, and RT dose at Point A significantly predicted overall survival. The survival prediction model demonstrated good calibration and discrimination. The bootstrap-corrected concordance index was 0.67. The predictive ability of the nomogram proved to be superior to FIGO stage (p = 0.01). Conclusions: The devised nomogram offers a significantly better level of discrimination than the FIGO staging system. In particular, it improves predictions of survival probability and could be useful for counseling patients, choosing treatment modalities and schedules, and designing clinical trials. However, before this nomogram is used clinically, it should be externally validatednically, it should be externally validated.

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

Energy Technology Data Exchange (ETDEWEB)

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)

Uterine cervical cancer. Preoperative staging with magnetic resonance imaging; Zervixkarzinom. Praeoperatives Staging mittels Magnetresonanztomographie  

Energy Technology Data Exchange (ETDEWEB)

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

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

DEFF Research Database (Denmark)

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.

Value of tenascin-C content and association with clinicopathological parameters in uterine cervical lesions.  

Science.gov (United States)

To determine whether the content of the matrix protein tenascin-C (Tn-C) is of diagnostic or prognostic value in cervical lesions, we evaluated increases in Tn-C immunoreactivity in 80 formalin-fixed, paraffin-embedded biopsies and surgical specimens of the uterine cervix. Tn-C content in the basement membrane zone and in the stroma was graded and compared to some prognostic parameters. In the normal cervix, Tn-C formed a thin continuous band. In cervicitis, Tn-C bands thickened in the basement membrane zone and the adjacent stroma in the form of thin filaments. In 30 squamous intraepithelial lesions (SILs) of various grades, Tn-C bands were either slightly (1+) or moderately (2+) thickened in the basement membrane zone, while slight stromal Tn-C immunoreactivity in the form of thin bands was observed in 12 cases, regardless of grade and inflammatory stromal reaction. In invasive carcinoma, Tn-C content was markedly increased in the stroma and around the invasive nests of tumors. The intensity of Tn-C immunoreactivity was significantly higher in grade I tumors than in others (p lesions and the appearance of Tn-C may be an indicator of adequate biologic defense in cervical cancer patients.

Assessment of the natural course and treatment of premalignant uterine cervical lesions in pregnancy  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Premalignant changes of the uterine cervix occur with similar frequency during pregnancy and in non­pregnant women. Due to the fact that any surgery on the cervix can jeopardize pregnancy, it is important to define the protocol of procedures for the treatment of these changes during pregnancy. Objective. The aim of the study was to investigate the natural course of premalignant cervical changes during pregnancy and the impact of their treatment on the pregnancy course. Methods. Study involved all patients with colposcopically, cytologically and hystopathologically diagnosed premalignant cervical changes during pregnancy from 2002 to 2008. Patients were divided into two groups according to the applied treatment during pregnancy: surgery or monitoring by regular colposcopic and cytological examinations. The two groups were compared concerning treatment outcome, persistence or regression of changes and pregnancy duration. Results. Study involved 58 patients. Spontaneous remission of lesions occurred after pregnancy in 63.79% of cases. Highgrade squamous intraepithelial lesion (H­SIL demonstrated a higher rate of persistency in comparison with low­grade squamous intraepithelial lesion (L­SIL (?2=25.115; p<0.05. Only one finding of L­SIL progressed into H­SIL in the monitored group. Patients who underwent conization during pregnancy had a significantly more frequent preterm deliveries (?2=14.369; p<0.05. Conclusion. The obtained high rate of spontaneous regression of cervical changes after pregnancy as well as the lower incidence of preterm births in patients who were not treated by conization during pregnancy, confirm that patients with premalignant cervical changes should be, if invasion is excluded, under follow­up throughout pregnancy by regular colposcopic and cytological examinations. Therapeutic conization, due to numerous complications, should be performed only when there is a suspected presence of a more severe form of the disease (micro invasive and invasive carcinoma.

Clinical significations of G2-M stage partial synchronization on radiation therapies of uterine cervical carcinomas  

International Nuclear Information System (INIS)

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

Histological classification of advanced uterine cervical cancer based on histogenesis and radiosensitivity  

International Nuclear Information System (INIS)

In the previous paper we reported a tentative histological classification of advanced uterine cervical cancers from a radiosensitivity view point. In this paper we tried to classify them into three groups based on their histogenesis; squamous cell carcinoma group, adenocarcinoma group and intermediate group. We found there is compatibility in these classifications based on radiosensitivity and histogenesis. The matrix cells in these three groups were considered as follows: 1) The original surface epithelia cells of ectocervix and immature reserve cells of the covering epithelium of the endocervix may be the type cells of the squamous cell carcinoma group. 2) The columnar or cuboidal epithelial cells covering the mucous surface of the endocervix and acinous cells of the mucous gland may be the type cells of the adenocarcinoma group. 3) And in the intermediate group the type cells may be of duct origin.

Evaluation by MR imaging of neoadjuvant intra-arterial infusion chemotherapy in uterine cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

Eight patients with uterine cervical cancer received two or three courses of neoadjuvant chemotherapy, including 254-S iv. and CDDP ia. Transcatheter arterial embolization (TAE) was added for seven patients. The therapeutic efficacy was evaluated by MR imaging and postoperative histopathological examination. Three patients achieved a complete response (CR) and five others were evaluated as a partial response (PR) on MR imaging. On postoperative histology, three of eight showed CR or PR, which coincided with MR findings. Viable cancer cells were shown in five patients. To detect these viable tumors, dynamic MR imaging was indispensable. However, because of limited spatial resolution, the detection of small residual tumors was not easy using dynamic MR imaging.

Ten cases of advanced uterine cervical carcinoma treated by radiohyperthermia and followed over five years  

Energy Technology Data Exchange (ETDEWEB)

The treatment of locally or regionally advanced carcinoma of the uterine cervix is still controversial. We present here ten advanced primary cases of uterine cervical squamous carcinomas treated between 1991 to 1992. The pelvic doses were 54.7{+-}3.8 Gy externally and 25.7{+-}2.7 Gy (point A) intracavitary. Hyperthermia (HT) was performed using a Thermotron RF8, and the effective heating times (>41 degC) was 202.4{+-}44.0 min/6.6{+-}0.8 sessions. The mean over-all treatment period was 59.4{+-}8.8 days. Acute adverse effects were observed in two patients, including umbilical burning and a subcutaneous consolidation cranial to the pubic bone. All the stage III patients (N=7) were locally controlled during their follow-up period. The overall 5-year survival rates for stages III and IVa (N=3) were 50% and 33%, respectively. The later results were relatively good in patients who did not develop hematogenous metastasis. The treatment administered was effective for the local control of stage III disease, but not for systemic control. Therefore, a new protocol for radio-chemo-hyperthermia is necessary for improving the survival rates. (author)

Squamous cell carcinoma antigen in serum for monitoring of head and neck and uterine cervical squamous cell carcinomas after radiotherapy  

International Nuclear Information System (INIS)

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

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

Uterine motility and cervical ripening in second trimester elective abortion by two different PGE analogues.  

Science.gov (United States)

The clinical effects were studied of two different PGE analogues on the uterine motility and cervical ripening of eighty pregnant women asking for a second trimester elective abortion for fetal abnormalities. Forty women received vaginal suppositories each containing 1 milligram of 16, 16-dimethyl-trans-s2-PGE1 (Gemeprost) every 3 hours (5 mg max). Intramuscular injections of 500 micrograms of 16-phenoxy-w 17, 18, 19, 20 tetranor PGE2 methyl-sulphonylamide (Sulprostone) were administered every four hours (2000 mcg max.) to the remaining forty patients. Thirty-three Gemeprost treated patients (82.5%) and 34 Sulprostone treated patients (85%) experienced a complete abortion in the mean of 12.92 +/- 6.95 hours and 11.88 +/- 6.8 hours respectively. The histological and ultrastructural findings of cervical ripening were similar in both groups, while the tocographic patterns showed different characteristics. Side effects occurred in 16 Sulprostone (40%), but only in 9 (22.5%) Gemeprost treated patients, demonstrating that Gemeprost, although equally effective, is better tolerated. PMID:1790608

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

Energy Technology Data Exchange (ETDEWEB)

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).

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 spatients 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.

Preterm birth due to cervical insufficiency complicated by placenta accreta and postpartum haemorrhage managed by uterine artery embolisation  

OpenAIRE

In this report, we present the case of a young woman undergoing her second pregnancy, with early detected shortened cervix resulting in cervical cerclage procedure. At gestational week 24/25, she presented at a hospital with signs of intra-amniotic infection and spontaneous rupture of membranes. This resulted in pathological preterm delivery with massive postpartum bleeding, which was managed by bilateral uterine artery embolization. Reasons for preterm birth and management options are discus...

High-dose-rate brachytherapy for uterine cervical cancer: the results of different fractionation regimen  

International Nuclear Information System (INIS)

Although high-dose-rate (HDR) brachytherapy regimens have been practiced with a variety of modalities and various degrees of success, few studies on the subject have been conducted. The purpose of this study was to compare the results of local control and late complication rate according to different HDR brachytherapy fractionation regimens in uterine cervical cancer patients. From November 1992 to March 1998, 224 patients with uterine cervical cancer were treated with external beam irradiation and HDR brachytherapy. In external pelvic radiation therapy, the radiation dose was 45 ? 54 Gy (median dose 54 Gy) with daily fraction size 1.8 Gy, five times per week. In HDR brachytherapy, 122 patients (Group A) were treated with three times weekly with 3 Gy to line-A (isodose line of 2 cm radius from source) and 102 patients (Group B) underwent the HDR brachytherapy twice weekly with 4 or 4.5 Gy to line-A after external beam irradiation. Iridium-192 was used as the source of HDR brachytherapy. Late complication was assessed from grade 1 to 5 using the RTOG morbidity grading system. The local control rate (LCR) at 5 years was 80% in group A and 84% in group B (? = 0.4523). In the patients treated with radiation therapy alone, LCR at 5 years was 60.9% in group A and 76.9% in group B (? = 0.2557). In post-operative radiation therapy patients, LCR at 5 years was 92.6% in group A and 91.6% in group B (? 0.8867). The incidence of late complication was 18% (22 patients) and 29lication was 18% (22 patients) and 29.4% (30 patients), of bladder complication was 9.8% (12 patients) and 14.7% (15 patients), and of rectal complication was 9.8% (12 patients) and 21.6% (22 patients), in group A and B, respectively. Lower fraction sized HDR brachytherapy was associated with decrease in late complication (? =0.0405) (rectal complication, ? = 0.0147; bladder complication, ? =0.115). The same result was observed in postoperative radiation therapy patients (? = 0.0860) and radiation only treated patients (? =0.0370). For radiation only treated patients, a greater number of itemized studies on the proper fraction size of HDR brachytherapy, with consideration for stages and prognostic factors, are required. In postoperative radiation therapy, the fraction size of HDR brachytherapy did not have much effect on local control, yet the incidence of late complication increased with the elevation in fraction size. We suggest that HDR brachytherapy three times weekly with 3 Gy could be an alternative method of therapy

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

Energy Technology Data Exchange (ETDEWEB)

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.

Quality of life in conventional and conformal pelvic radiotherapy for cervical and uterine cancer  

International Nuclear Information System (INIS)

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 qualipaired 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)

Anti-Müllerian hormone in premenopausal women following treatment of uterine cervical cancer.  

Science.gov (United States)

In this longitudinal study we prospectively enrolled 32 premenopausal women (ages 23-44 years) with stage I-III uterine cervical cancer undergoing surgery and/or chemoradiation. Serum levels of anti-Müllerian hormone, follicle-stimulating hormone and estradiol were examined at baseline and 1 year after treatment. As expected, serum anti-Müllerian hormone was undetectable after salpingo-oophorectomy or chemoradiation. After radical hysterectomy and pelvic lymphadenectomy with ovarian preservation serum anti-Müllerian hormone declined from a mean value of 2.0 ± 1.4 ?g/L to 1.1 ± 0.8 ?g/L (p = 0.01), representing a 45% reduction, whereas there was no significant change in serum levels of follicle-stimulating hormone and estradiol. This implies that ovarian function may be affected not only by castrating treatment but also by radical hysterectomy with ovarian preservation. The risk of premature menopause and the potential need of hormone replacement therapy among these women may be overlooked since they no longer menstruate. PMID:24985038

Lexington studies of Cf-252 brachytherapy for advanced cervical and uterine cancer  

Energy Technology Data Exchange (ETDEWEB)

The most important tumors selected for study in the Lexington clinical trial of /sup 252/Cf have been the advanced stages of cervical cancer, i.e. stage III and IV. These tumors are poorly controlled by conventional photon radiotherapy and local persistence or pelvic recurrence of tumor occurs commonly after radiotherapy in 60-90% of treated patients. During 1975-1979, a group of patients were treated using conventional radiotherapy with delayed /sup 137/Cs implants, experimental radiation using a delayed /sup 252/Cf implant instead of /sup 137/Cs, and early /sup 252/Cf implants before pelvic irradiation. These schedules and the clinical responses of tumors were studied in sequential studies in the authors' clinic. The characteristics of tumor responses are reviewed as well as patient survival. The early implant schedule was developed to treat tumors when they were of maximal size and presumably radioresistance, presumed due to hypoxia. 5-year survival rates were determined for the different treatments and was 54% for the Cf implants performed early and approximately 15% when delayed /sup 137/Cs or /sup 252/Cf implants were used. These studies indicate that implant schedule was important to outcome for /sup 252/Cf neutron brachytherapy and that the early implant of cervix cancer conferred an advantage for tumor control. Primary and recurrent uterine carcinomas were also studied and were found to be neutron sensitive.

Relationship between the cervical uterine cancer evolution and selenium concentration in urine determined by NAA  

International Nuclear Information System (INIS)

Neutron activation analysis of Se in urine reaches an optimum sensitivity (few ppb) and precision (± 12%) when the traces are complexed without using a carrier by ammonium pyrrolidindithiocarbamate (APDC) at pH 1.5-2 and adsorbed on activated carbon filters. In this way the selenium traces analysis have been carried out through 77mSe in 45 urine samples on a pre-separation basis by cyclic activation of the carbon filters. The selenium concentration in our blanks is virtually zero, because APDC proved to be selenium free and selenium mass in 50 mg of activated carbon used as a filter is 20 times below our qualitative detection limit and 144 times below our quantitative detection limit. The samples were first of day urine from healthy and ill women suffering cervical uterine cancer, at different evolution stages: incipient, intermediate and advanced, with no treatment, and surgery, radiotherapy, chemotherapy, or a combined treatment. The results show a consistent trend to increase the selenium trace concentration during the intermediate stage, whereas it is the same than normal for incipient cases, and it decreases to the lowest concentrations for advanced cases.

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.

Therapeutic Results of Concurrent Chemoradiation in Locally Advanced Uterine Cervical Cancer  

International Nuclear Information System (INIS)

Purpose : Despite a development for therapeutic machines and advance in modern radiation therapy techniques, locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate. Combination of chemotherapy and radiotherapy demonstrated benefit in improving local control and possibly the overall survival. Our study was performed to evaluate effect of concurrent chemoradiation on locally advanced uterine cervical cancer. Methods and Materials : Twenty six patients with locally advanced stage(FIGO stage IIB with ? 5 cm in diameter, III, IVA) were treated with combination of radiation therapy and concurrent cisplatinum between May of 1988 and September of 1993 at our hospital. Radiation therapy consisted of external irradiation and 1-2 sessions of intracavitary irradiation, Cisplatinum was administered in bolus injection of 25mg/m2 at weekly intervals during the course of external radiation therapy. Results : Of the 26 patients, twenty-five patients were evaluable for estimation of response. Median follow-up period was 25 months with ranges from 3 to 73 months. Stage IIB, III, and IVA were 16, 5,4 patients, respectively. Twenty patients were squamous cell carcinoma. Response was noted in all 25 patients: complete response(CR) in 17/25(68%), partial response(PR) in 8/25(32%). Of the 24 patients except one who died of sepsis at 3 months follow-up, seventeen patients(70.8%) maintained local control in the pelvis: 16/17(94.1%) in CR, 1rol in the pelvis: 16/17(94.1%) in CR, 1/17(14.3%) in PR. Fourteen of the 17 patients with CR are alive disease free on the completion of follow-up. Median survival is 28 months for CR and 15 months for PR. Analysis of 5-year survival by stage shows 11/16(59.8) in IIB, 3/5(60.6%) in III, and 1/4(25.0%) in IVA. Overall 5-year survival rate was 55.2%. Ten Patients recurred: 4 at locoregional, 3 in distant metastasis and 3 with locoregional and distant site. Toxicity by addition of cisplatinum was not excessive. Conclusion : Although the result of this study was obtained from small number of patients, it is rather encouraging in view of markedly improved response rate compared with the results of historical group

Therapeutic Results of Postoperative Radiation Therapy for Early Stage Uterine cervical Cancer  

International Nuclear Information System (INIS)

This is a retrospective analysis of 67 patients with histologically proven invasive carcinoma of uterine cervix treated with surgery followed by adjuvant radiotherapy at Inje University Seoul Paik Hospital between october 1983 and september 1991. Postoperative radiotherapy was carried out in patients with high risks of locoregional recurrence such as positive pelvic lymph node (38 pts), large tumor size more than 3 cm (22 pts), cervical stromal invasion more than 2/3 (46 pts), parametrial involvement (9 pts), positive resection margin (147ts), endo/myometrial extension (10 pts), and angiolymphatic invasion (13 pts). Stage IA, IB, and IIA were 2(3%), 39(58.2%), and 26(38.8%), respectively. Median follow-up period was 48 months with ranges from 13 to 115 months. All 67 patients were treated externally with standard pelvic field with radiation dose ranging from 4080 to 6120 cGy in 4-6 weeks period of time. Of these, 45 patients received intracavitary radiotherapy. The overall survival rate and disease free survival rate at 5-year were 88.0% and 82.1%, respectively. The survival rates by stage were 87.l% in IB and 88.4% in IIA. Local control rate was 86.6%(58 pts). The treatment failure was noted in 12 of 67 Patients(17.9%): locoregional failure in 7(10.4%), distant metastasis in 3(4.5%), and locoregional and distant metastasis in 2 (3%). The univariate analysis of prognostic factors disclosed endo/myometrial extension as a significant factor of survival and recurrence (7icant factor of survival and recurrence (70.0% vs 91.l% P<0.05 and 30.0% vs 15.8%, respectively). The complication of postoperative radiotherapy was not significant and all patient were well tolerated. In conclusion, postoperative radiotherapy in patients with high risks of locoreginal recurrence is relatively well tolerated and it gives significantly improved survival rate especially in patients with positive lymph nodes, bulky tumor size( 3 cm), parametrial involvement, cervical stromal invasion more than 2/3, positive resection margin and angiolymphatic invasion

Predictive role of post-treatment [{sup 18}F]FDG PET/CT in patients with uterine cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

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.

Postoperative radiotherapy for uterine cervical cancer. Results of the 1995-1997 patterns of care process survey in Japan  

International Nuclear Information System (INIS)

The objective of this study was to determine the average national practice of postoperative radiotherapy (RT) for uterine cervical cancer in Japan. The Japanese Patterns of Care Study (PCS) reviewed the process of care employed for 455 uterine cervical cancer patients who were treated with surgery followed by postoperative RT during 1995-1997. Cases with missing data were excluded from calculations of percentage and significance for each of the surveyed items. According to International Federation of Gynecology and Obstetrics (FIGO) stages, 198 patients (45%) were in stage I, 52 patients (12%) were in stage IIA, 146 patients (33%) were in stage IIB and 46 patients (10%) were in stage III/IVA. The most common surgical procedure among the patients was radical hysterectomy (73%). Three hundred and seventy patients (82%) were treated with external beam RT (ERT) alone, and 74 patients (17%) were treated with a combination of ERT and intracavitary RT (ICRT). A midline block was used for the pelvic field in 63 patients (14%). Only seven patients (2%) were treated with extended field ERT. Pelvic ERT was most often performed using anterior posterior-posterior anterior (AP-PA) opposed fields for 431 patients (97%). A majority of the patients (312 patients, 70%) were treated with a total dose of 45.0-50.4 Gy for ERT. Chemotherapy (CT) was administered to 178 patients (40%), neoadjuvant preoperative CT was administered to 80 patients (22%) and concurrent CT with postoperative RT ) and concurrent CT with postoperative RT was administered to 29 patients (8%). This PCS established the national practice average of postoperative RT for uterine cervical cancer. Follow-up studies need to be conducted to determine whether the observed differences in treatment processes affect outcomes. (author)

Blood flow MR imaging of the uterine arteries and of normal and malignant cervical tissue. Initial experiences with a 2D-STAR technique  

International Nuclear Information System (INIS)

Purpose. The aim of this pilot study was to evaluate a 2D-STAR technique as a non contrast-enhanced approach to demonstrate the uterine artery and its branches and to assess the cervical uterine blood flow in healthy volunteers and in patients with advanced uterine cervical carcinoma. Materials and methods. Seven healthy volunteers (mean age, 29 years) and twentytwo patients (mean age, 52 years) with advanced cancer of the uterine cervix (FIGO IIB-IVA) were prospectively examined by 2D-STAR imaging at different inversion delay times (300 ms-1900 ms) which showed the passage of a blood bolus through normal and malignant tissue of the uterine cervix. Results. The uterine artery was well visualized with short inversion delay times of 300 ms to 500 ms. It was characterized as single or multiple helical loops before dividing into its intracervical branches. The intracervical branching was observed at inversion delay times of 500 ms-700 ms. With longer inversion delay times arterial signal enhancement disappeared and cervical tissue enhancement was noted. Enhancement of benign tissue was observed at inversion delay times of 1100 ms-1700 ms, and in malignant tissue at shorter inversion delay times of 900 ms-1300 ms. The maximum of this diffuse signal enhancement of benign tissue was seen at inversion dealy times of 1500 ms (1100 ms-1700 ms), in malignant tissue at significantly (P<0.05) shorter inversion delay times of 1100 ms (900 ms to 1300).

Preoperative [{sup 18}F]FDG PET/CT maximum standardized uptake value predicts recurrence of uterine cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

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.)

Neoadjuvant chemotherapy with bleomycin, ifosfamide and nedaplatin (NAC-BIN) followed by radiotherapy in locoregionally advanced uterine cervical cancer  

Energy Technology Data Exchange (ETDEWEB)

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.

Retrospective analysis of concurrent chemoradiation with the combination of bleomycin, ifosfamide and cisplatin (BIP) for uterine cervical cancer  

International Nuclear Information System (INIS)

Combination chemotherapy consisting of bleomycin, ifosfamide, and ciplatin (BIP) is recognized as one of the most effective chemotherapies for uterine cervical cancer. However, there have been no reports that evaluate concurrent use of radiation with BIP. The objective of this study was to evaluate the toxicity and response of the combination of BIP concurrent with radiation in patients with squamous cell carcinoma of the uterine cervix. Eligibility criteria included patients who underwent radical hysterectomy (Type III hysterectomy) as a primary treatment and revealed lymph node metastases or deep myometrial invasion (stage IB and IIA) and patients who were previously untreated (stage IIB-IV). All of the patients had biopsy-proven squamous cell carcinoma of the uterine cervix. The patients received three courses of BIP chemoradiation, and the response and toxicity were evaluated. From January 2000 to December 2003, 30 patients met study eligibility criteria. All but three patients completed 3 courses of planned chemotherapy. The frequency of severe (grade 3 and 4) toxicity was as follows: anemia, 46.7%; neutrocytopenia, 73.3%; thrombocytopenia, 16.7%; and nausea and vomiting, 23.3%. Among 30 patients, 22 cases were evaluated for response. Complete response was achieved in 16 (72.7%) of patients, with a response rate of 90.9%. In conclusion, BIP chemoradiation seems to be superior to previously reported chemoradiation regimens, and has a potential as an optimal combin, and has a potential as an optimal combination chemotherapy concurrent with radiation.

Quantification of delineation errors of the gross tumor volume on magnetic resonance imaging in uterine cervical cancer using pathology data and deformation correction.  

Science.gov (United States)

Abstract Background. To safely optimize target volumes using magnetic resonance imaging (MRI) for uterine cervical cancer radiation therapy, MRI findings need to be validated. The aim of this study was to correlate pre-operatively acquired MRI and surgical specimen imaging for uterine cervical cancer patients using deformable image registration and quantify gross tumor volume (GTV) delineation discrepancies. Material and methods. For 16 retrospectively selected early-stage uterine cervical cancer patients, the cervix-uterus structure, uterine cavity and the GTV were delineated on 2D pathology photos after macroscopic intersection and corresponding pre-operatively acquired T2-weighted 2D sagittal MR images. Segmentations of pathology photos and MR images were simultaneously registered using a three-step multi-image registration strategy. The registration outcome was evaluated by the Dice similarity coefficient (DSC) and the surface distance error (SDE). In addition, GTV expansions within the cervix-uterus structure needed to obtain 95% GTV coverage were determined. Results. After three-step multi-image registration, the median DSC and median SDE were 0.98 and 0.4 mm (cervix-uterus) and 0.90 and 0.4 mm (uterine cavity), respectively. The average SDE around the GTV was 0.7 mm (range, 0.1 mm - 2.6 mm). An underestimation of MRI-based GTV delineations was found when no margin was applied, indicated by a mean GTV coverage of 61%. To obtain 95% GTV coverage for 90% of the patients, a minimum 12.0 mm margin around MRI-based GTVs was needed. Conclusion. The presented three-step multi-image registration strategy was suitable and accurate to correlate MRI and pathology data for uterine cervical cancer patients. To cover the pathology-based GTV, a margin of at least 12.0 mm around GTV delineations on T2-weighted MRI is needed. PMID:25437811

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 faoved to be a significant prognostic factor in OS. Using these three parameters, we devised a practical and effective model to predict OS. (author)

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 NA determining factor for the response to NAIC

High dose-rate brachytherapy for elderly patients with uterine cervical cancer  

International Nuclear Information System (INIS)

The need for radiotherapy (RT) in cancer treatment for the elderly patient is growing. The purpose of this study was to analyze the efficacy and complication rate for radiotherapy, using external-beam irradiation (EBRT) and high dose-rate intracavitary brachytherapy (HDRICB), for patients aged 70 years or older with carcinoma of the uterine cervix. From September 1992 to December 1997, 295 patients diagnosed with uterine cervical cancer completed RT at the Shin Kong Memorial Hospital and China Medical College Hospital. Two hundred and fifty-eight patients [International Federation of Gynecology and Obstetrics (FIGO) stage distribution: 35 Ib, 26 IIa, 122 IIb, 10 IIIa, 58 IIIb, 7 IVa] who had undergone at least two courses of HDRICB and a minimum of 3 years of follow-up, were evaluated. A retrospective analysis was conducted to compare the outcome of radiation therapy for the 179 patients under 70 years of age (younger group) and the 79 patients aged 70 years or older (older group). The RT consisted of EBRT followed by HDRICB. After a total EBRT dose of 40-45 Gy/20 in 25 fractions, irradiating the whole pelvis over 4-5 weeks, dosage for patients diagnosed as FIGO stage IIb-IVa bilateral parametrial disease was boosted to 54-58 Gy, with central shielding. HDRICB was administered at 1-week intervals using an Ir-192 remote after-loading technique. Ninety-nine patients (38.4%) received three fractions of HDRICB, while 156 patients (60.5%) had four fractions. Total prescrib(60.5%) had four fractions. Total prescribed Point A dosages (EBRT+HDRICB) ranged from 58 to 71.6 Gy (median, 65.6 Gy) for stage IB-IIA, while for larger lesions (stage IIB-IVA) analogous dosages were 59-75.6 Gy (median, 65.6 Gy). Median follow-up durations for the older and younger groups were 56/55 months, respectively. The respective 5-year actuarial survivals (AS) for the older and younger groups were 82/85% for stage Ib, 65/65% for IIa, 61/71% for IIb and 35/59% for IIIa-b. The 5-year cause-specific survivals (CSS) for the older and younger groups were 100/95% for stage Ib, 85/75% for IIa, 78/72% for IIb and 42/61% for IIIa-b. The 5-year pelvic relapse-free survivals (PRFS) for the older and younger groups were 100/100% for stage Ib, 91/93% for IIa, 91/90% for IIb and 67/80% for IIIa-b. The 5-year distant metastasis-free survivals (DMFS) for older and younger groups were 100/100% for stage Ib, 92/88% for IIa, 84/73% for IIb and 55/75% for IIIa-b. There was no statistically significant survival difference on comparing the two groups according to stage. The gross tumor-free ratios after EBRT (NRT) for the older and younger groups were 44.3/24.5% (P=0.001). The 5-year CSS for the 35 NRT patients was 88% for the older group, while for the 44 patients diagnosed with gross residual tumor after EBRT (GRT) it was 64% (P=0.001). Twelve (15.0%) of the 79 older patients and 14 (7.8%) of the 179 younger patients developed Radiation Therapy Oncology Group (RTOG) grade 3-4 rectal complications (P=0.12), while seven (8.9%) of the 79 older patients and 10 (5.6%) of the 179 younger patients developed RTOG grade 3-4 small bowel complications (P=0.34). Radiation therapy, consisting of a combination of EBRT and three or four fractions of HDRICB, proved to be effective for older patients. Further optimization of treatment policy is essential by changing the HDRICB fractionation strategy, shortening the treatment time and designing combination drug regimens that are both effective and tolerable during radiotherapy.

Cerebellar metastases in patients with uterine cervical cancer. Two cases reports and review of the literature; Metastases cerebelleuses chez des patientes atteintes d'un cancer du col uterin. A propos de deux cas et revue de la litterature  

Energy Technology Data Exchange (ETDEWEB)

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)

Calmodulin antagonists increase the expression of membrane-type-1 matrix metalloproteinase in human uterine cervical fibroblasts.  

Science.gov (United States)

The treatment of human uterine cervical fibroblasts with concanavalin A (ConA), or a specific calmodulin antagonist, N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide (W-7) or trifluoperazine resulted in accumulation of an active form of matrix metalloproteinase 2 (MMP-2, gelatinase A). In contrast, N-(6-aminohexyl)-1-naphthalenesulfonamide (W-5), a weaker antagonist of calmodulin, did not modulate the activation of proMMP-2. The activation of proMMP-2 was confirmed by the enhanced activity on gelatin and the conversion of proMMP-2 to a 62-kDa form by zymography and western blotting. The plasma membrane, but not the conditioned medium, of the W-7- or trifluoperazine-treated cells activated proMMP-2; this activation was blocked by membrane-type-1 MMP (MT1-MMP) antibody and EDTA. The plasma membrane from trifluoperazine- or ConA-treated cells contained MT1-MMP and tissue inhibitor of metalloproteinases 2. Both trifluoperazine treatment and ConA treatment increased the steady-state levels of MT1-MMP mRNA and proMMP-2 mRNA. These results, together with our previous observations on the production of proMMP-1 (interstitial procollagenase) and proMMP-3 (prostromelysin 1) [Ito, A., Sato, T., Ojima, Y., Chen, L.-C., Nagase, H. & Mori, Y. (1991) J. Biol. Chem. 266, 13598-13601], suggest that calmodulin negatively regulates the matrix turnover by suppressing the production of a number of proMMPs including proMMP-1, proMMP-3 and MT1-MMP, and the activation of proMMP-2 in human uterine cervical fibroblasts.

Expression of Bmi-1, P16, and CD44v6 in Uterine Cervical Carcinoma and Its Clinical Significance  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: Bmi-1, a putative proto-oncogene, is a core member of the polycomb gene family, which is expressed in many human tumors. The p16 protein negatively regulated cell proliferation, whereas CD44v6 is associated with proliferation as an important protein. Additionally, CD44v6 is an important nuclear antigen closely correlated to tumor metastasis. The present study aims to investigate the expression and significance of Bmi-1, p16, and CD44v6 in uterine cervical carcinoma (UCC. Methods: A total of 62 UCC, 30 cervical neoplasic, and 20 normal cervical mucosal tissues were used in the current study. The expression of Bmi-1, p16, and CD44v6 in these tissues was determined using immunohistochemical assay. The relationships among the expression of these indices, the clinicopathologic features of UCC, and the survival rate of UCC patients were also discussed. The correlation between Bmi-1 protein expression and p16 or CD44v6 protein in UCC was analyzed. Results: The expression of Bmi-1, p16, and CD44v6 was significantly high in cervical carcinoma compared with that in the cervical neoplasia and normal colorectal mucosa (P0.05. The Kaplan–Meier survival analysis showed that the over-expression of Bmi-1 significantly decreased the survival rate of UCC patients (P<0.05. A strong correlation indicated that there was statistical significance between the expression of Bmi-1 and CD44V6 proteins in UCC (r=0.419, P=0.001. Conclusions: The over-expression of Bmi-1 and CD44v6 protein closely correlate to the tumorigenesis, metastasis, and prognosis of UCC. Bmi-1 and CD44v6 may be used to predict the prognosis of cervical carcinoma. Bmi-1 may indirectly regulate the expression of CD44v6 in UCC patients. The positive expression of p16 protein is possibly associated with the tumorigenesis, but not with the metastasis or prognosis of UCC.

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), 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)

Results of radiation alone versus neoadjuvant chemotherapy and radiation in locally advanced stage of uterine cervical cancer  

International Nuclear Information System (INIS)

This is retrospective study to compare the results of radiation therapy alone and neoadjuvant chemotherapy and radiation in advanced stage of uterine cervical cancer. Seventy-six patients who were treated with definitive radiation therapy for locally advanced cervical carcinoma between June 1988 and December 1993 at the department of radiation oncology, Keimyung University Dong-san Hospital. Thirty six patients were treated with radiation therapy alone and forty patients were treated with cisplatin based neoadjuvant chemotherapy and radiation therapy. According to FIGO staging system, there were 48 patients in stage IIb, 3 patients in stage IIIa, 23 patients in stage IIIb and two patients in stage IVa with median age of 53 years old. Follow-up periods ranged from 7 to 95 months with median 58 months. Complete response (CR) rate were 86.1% in radiation alone group and 80% in chemoradiation group. There was no statistical difference in CR rate between the two groups. Overall five-year survival rate was 67.3%. According to stage, overall five-year survival rates were 74% in stage IIb, 66.7% in stage IIIa, 49.8% in stage IIb, 50% in stage IVa. According to treatment modality overall five year survival rates were 74.1% in radiation alone and 61.4% in chemoradiation group (P=0.4). Five year local failure free survival rates were 71.5% in radiation alone group and 60% in chemoradiation group (P=0.17). Five year distant metastasis free survival rates were 80.3% in radiation ae survival rates were 80.3% in radiation alone group and 89.9% in chemoradiation group (P=0.42). Bone marrow suppression was noted in 3 cases of radiation alone group and 1 case of chemoradiation group. Grade II retal complication was noted in 5 patients of radiation group and 4 patients in chemoradiation group. Bowel obstruction treated with conservative treatment (1 patient) and bowel performance treated with surgery (1 patient) were noted in radiation alone group. There was no statistical difference in complication between two groups. There was no statistical difference in survival, failure and complication between neoadjuvant chemotherapy and radiation versus radiation alone in locally advanced uterine cervical carcinoma.

Metastatic cervical lymphadenopathy from uterine leiomyosarcoma with good local response to radiotherapy and chemotherapy  

International Nuclear Information System (INIS)

The metastasis of uterine leiomyosarcoma to the neck node has not been reported previously and the radiotherapy has been rarely used for the metastatic lesion of the other sites. We report a case of neck metastasis from a uterine leiomyosarcoma, which developed 10 months after surgery and postoperative pelvic radiotherapy. It also involved the parapharyngeal space, adjacent spine, and spinal canal. The metastatic neck mass was inoperable, and was treated by neck radiotherapy (6,000 cGy) and chemotherapy including taxol and carboplatin. The mass has regressed progressively to a nearly impalpable state. She has never developed spinal cord compression syndrome, and has maintained good swallowing for eight months since the neck radiotherapy and chemotherapy. Since the extensive metastatic neck mass showed good local response to high dose radiotherapy and chemotherapy, both treatments may be considered for an unresectable metastatic leiomyosarcoma

She has never developed spinal cord compression syndrome, and has maintained good swallowing for eight months since the neck radiotherapy and chemotherapy. Since the extensive metastatic neck mass showed good local response to high dose radiotherapy and chemotherapy, both treatments may be considered for an unresectable metastatic leiomyosarcoma.

Plasma levels of cortisol and oxytocin, and uterine activity after cervical artificial insemination in the ewe  

OpenAIRE

The objective was to compare in the ewe the effects of easy and difficult procedures for artificial insemination (AI) (as related to rapid or poor accessibility of the cervix, respectively) on plasma cortisol (CORT) and oxytocin (OT), and uterine motility. All AI were simulated using a catheter empty of semen to study genital and environmental stimuli only. In experiment 1, 40 ewes were sampled after AI, and whether it was an easy or difficult procedure was reported for each animal. While COR...

Genomic amplification of the human telomerase gene (hTERC associated with human papillomavirus is related to the progression of uterine cervical dysplasia to invasive cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Human papillomavirus (HPV infection plays an etiological role in the development of cervical dysplasia and cancer. Amplification of human telomerase gene (hTERC and over expression of telomerase were found to be associated with cervical tumorigenesis. This study was performed to analyze genomic amplification of hTERC gene, telomerase activity in association with HPV infection in different stages of cervical intraepithelial neoplasia (CIN and cervical cancer. We were studying the role of hTERC in the progression of uterine cervical dysplasia to invasive cancer, and proposed an adjunct method for cervical cancer screening. Methods Exfoliated cervical cells were collected from 114 patients with non neoplastic lesion (NNL, n=27, cervical intraepithelial neoplasia (CIN1, n=26, CIN2, n=16, CIN3, n=24 and cervical carcinoma (CA, n=21, and analyzed for amplification of hTERC with two-color fluorescence in situ hybridization (FISH probe and HPV-DNA with Hybrid Capture 2. From these patients, 53 were taken biopsy to analyze telomerase activity by telomeric repeat amplification protocol (TRAP and expression of human telomerase reverse transcriptase (hTERT, with immunohistochemistry (IHC. All biopsies were clinically confirmed by phathologists. Results Amplification of hTERC was significantly associated with the histologic diagnoses (p Conclusions hTERC ampliffication can be detected with FISH technique on exfoliated cervical cells. Amplification of hTERC and HPV infection are associated with more progressive CIN3 and CA. The testing of hTERC amplification might be a supplementary to cytology screening and HPV test, especially high-risk patients.

Apparent rarity of asymptomatic herpes cervicitis in a woman with intra-uterine contraceptive device  

Directory of Open Access Journals (Sweden)

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.

[Uterine cancer].  

Science.gov (United States)

It is thought that robotic surgery is highly useful for uterine malignant tumor such as endometrial cancer and cervical cancer. It is nothing but that robotic surgery enables us the correct and delicate movement of forceps, which is necessary for operative procedures at the deep and narrow space in the pelvic cavity and the perivascular lymphadenectomy. By our experience, significant reduction of blood loss and shortening of the hospital stay were accepted in the cases of endometrial cancer and cervical cancer. At present the robotic surgery in uterine cancer in Japan lags far behind the USA In order not to miss the trend in the world, it is required for the robotic surgery of uterine cancer to spread widely in Japan from now on. For this purpose, it is necessary to accumulate cases on the assumption that advanced medical care and also insurance adaptation. PMID:25434437

Optimum Dose Combination of External Radiation and High Dose Rate ICR in FIGO IB Uterine Cervical Cancer  

International Nuclear Information System (INIS)

Purpose : To assess the efficacy of high dose rate - intracavitary radiotherapy (HDR-ICR) in the radiotherapy of FIGO stage IB squamous cell carcinoma of uterine cervix and to determine the optimum dose combination xheme of external radiotherapy and ICR to achieve acceptable local control without severe complication. Methods and Materials : One hundred and sixty two patients with FIGO stage Ib squamous cell carcinoma of uterine cervix who received definitive radiotherapy between May 1979 and December 1990 were retrospectively analyzed. All the patients received external radiotherapy combined with HDR-ICR. External dose of 40-46 Gy in 4.5-5 weeks was given to whole pelvis(median 45 Gy) and ICR dose of 30-39 Gy in 10-13 times was given to the point A. Midline shielding was done after 20-45 Gy of external radiotherapy(median 40 Gy). Summation of external dose plus ICR dose to the point A range were 64.20-95.00 Gy, and mean was 83.94 Gy. We analyzed the local control rate, survival rate, and late complication rate. Results : Initial complete response rate was 99.4% for all patients. Overall 5-year survival rate was 91.1% and 5-year disease free survival rate was 90.9%. Local failure rate was 4.9% and distant failure rate was 4.3% Tumor size was the only significant prognostic factor. When tumor size greater than 3cm, 5-year survival rate was 92.6% and less than 3cm, that was 79.6%, Late complication rate was 23.5% with 18.5% of rectal complication and 4.9% of bladder compctal complication and 4.9% of bladder complication. Mean rectal dose summation of external midline dose plus ICR rectal point dose was lower in the patients without rectal complication(74.88 Gy) than those with rectal complication (78.87 Gy). Complication rate was increased with low rate of improvement of survival rate when summation of external midline dose plus point A or point R dose by ICR was greater than 70-75 Gy. Conclusion : The definitive radiation therapy using high dose rate ICR in FIGO stage IB uterine cervical cancer is effective treatment modality with good local control and survival rate without severe complication

Clinical study on protective of glutathione from radiation injuries in uterine cervical cancer  

International Nuclear Information System (INIS)

The protective effects of glutathione (GSH) against radiation were studied by the single, blind method in patients with carcinoma of the uterine cervix treated by radiotherapy. The background factors were same in the GSH group as in the control group. The results revealed that the occurrence of abnormal values of WBC, PLT, GOT, GPT and hematocrit in the GSH group were significantly lower than those in the control group by signed rank test, which suggests a possibility that GSH prevents these blood findings from becoming abnormal. In subjective or objective symptoms, the appearance of general lassitude was significantly reduced in the GSH group. Blood findings were studied in relation to NSD. (auth.)

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 rametrial 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)

Sonoporation of Cervical Carcinoma Cells Affected with E6-Oncoprotein for the Treatment of Uterine Cancer  

Science.gov (United States)

Cervical cancer has been identified as the third leading cause of average years of life lost per person dying of cancer. Since essentially all cervical cancers contain copies of human papillomavirus (HPV) DNA, we propose a treatment that targets HPV-infected cells using strategies that re-introduce normal functions into the infected cells while sparing healthy cells. We propose the use of focused ultrasound in combination with microbubbles as means to deliver antibodies against the E6 protein present only in HPV positive cells. We conducted in vitro studies with cell cultures of SiHa cervical carcinoma cells seeded into Opticell™ chambers. An in-house ultrasound excitation apparatus was used to control and explore the optimal acoustic parameters in order to maximize delivery. We first validated the possibility of delivering the EX-EGFP-M02 vector (Genecopoeia) into the cells; 1.2 ?L of activated microbubbles (Definity®) and 50 ?g of the vector were mixed in media and then injected into the Opticell™ chamber. We used 32 ?s pulses at a central frequency of 930 KHz with a repetition frequency of 1.5 kHz and total exposure duration of 30 s; six pressure values were tested (0 to 1 MPa). Fluorescence imaging was used to determine the levels of intracellular proteins and assess delivery. The delivery of an anti-?-Tubulin antibody was next tested and confirmed that the delivery into HPV16 positive cells was successful.

Dose optimization of fractionated external radiation and high-dose-rate intracavitary brachytherapy for FIGO stage IB uterine cervical carcinoma  

International Nuclear Information System (INIS)

Purpose: To determine the optimal dose combination scheme of external beam radiotherapy (EBRT) and high-dose-rate (HDR) intracavitary radiation (ICR) for maximizing tumor control while conferring an acceptable late complication rate in the treatment of Stage IB uterine cervical cancer. Methods and Materials: We retrospectively analyzed 162 patients with International Federation of Gynecology and Obstetrics (FIGO) Stage IB squamous cell carcinoma of the uterine cervix who received definitive RT between May 1979 and December 1990. Before HDR-ICR, all patients received EBRT to a total dose of 40-46 Gy (median 45), administered during 4-5 weeks to the whole pelvis. HDR-ICR was given 3 times weeks to a total dose of 24-51 Gy (median 39) at point A, using a dose of 3 Gy/fraction. Central shielding from EBRT was begun after the delivery using 20-45 Gy (median 40) of the external dose. The total dose to point A, calculated by adding the EBRT biologically effective dose (BED) and the ICR BED to point A, was 74.1-118.1 Gy (mean 95.2). The rectal point dose was calculated at the anterior rectal wall at the level of the cervical os. The local control rate, survival rate, and late complication rate were analyzed according to the irradiation dose and BED. Results: The initial complete response rate was 99.4%. The overall 5-year survival rate and 5-year disease-free survival rate was 91.1% and 90.9%, respectively. The local failure rate was 4.9%, and the distant failure rate was 4.34.9%, and the distant failure rate was 4.3%. Late complications were mild and occurred in 23.5% of patients, with 18.5% presenting with rectal complications and 4.9% with bladder complications. The mean rectal BED (the sum of the external midline BED and the ICR rectal point BED) was lower in the patients without rectal complications than in those with rectal complications (125.6 Gy vs. 142.7 Gy, p=0.3210). The late rectal complication rate increased when the sum of the external midline BED and the rectal BED by ICR was ?131 Gy (p=0.1962). However, 5-year survival rates did not increase with the external midline BED (p=0.4093). The late rectal complication rate also increased, without a change in the survival rate, when the sum of the external midline BED and the ICR point A BED was >90 Gy. Conclusion: In treating Stage IB carcinoma of the uterine cervix with HDR-ICR, using fractions of 3 Gy, it is crucial to keep the point A BED at ?90 Gy to minimize late rectal complications without compromising the survival rate. To achieve this goal, appropriate central shielding from EBRT is needed

Optimum dose combination of external radiation and high dose rate ICR in FIGO stage IB uterine cervical cancer  

International Nuclear Information System (INIS)

Purpose: To determine the optimum dose combination scheme of external radiotherapy and high-dose-rate intracavitary radiation(HDR-ICR) to maximize tumor control with an acceptable range of late complication rate in the treatment of stage IB uterine cervical cancer. Materials and Methods: One hundred and sixty two patients with FIGO stage IB squamous cell carcinoma of uterine cervix who received definitive radiotherapy between May 1979 and December 1990 were retrospectively analyzed. All the patients received external irradiation with a total dose of 40-46 Gy in 4(1(2))-5 weeks to the whole pelvis and HDR-ICR with a total dose of 24-51 Gy in 8-17 fractions to the point A(median 39 Gy). ICR was given three times a week with a dose of 3 Gy per fraction. Midline shielding was done after 20-45 Gy of external radiotherapy(median 40 Gy). Summation of the external radiation dose and ICR dose to the point A was 64.2-95 Gy(mean 83.9 Gy). The rectal point dose was calculated at the anterior rectal wall at the level of cervical os. The local control rate, survival rate, and late complication rate were analyzed according to the irradiation dose. Results: The initial complete response rate was 99.4% for all patients. The overall 5-year survival rate and 5-year disease free survival rate were 91.1% and 90.9%, respectively. Local failure rate was 4.9% and the distant failure rate was 4.3%. The RTOG Grade I and II late complication rate was 23.5% with 18.5% presenting with rectal comp.5% with 18.5% presenting with rectal complications and 4.9% with bladder complications. There was no grade III or IV complication. Mean rectal dose (summation of external midline dose and ICR rectal point dose) was lower in the patients without rectal complications than those with rectal complications(74.9 Gy vs. 78.9 Gy). The late rectal complication rate was increased when the summation of the external midline dose and rectal dose by ICR was more than 70 Gy(3% for 40-59 Gy, 2% for 60-69 Gy, 10% for 70-79 Gy, 9% for 80-89 Gy, 7% for 90 Gy or more, p-value was 0.5). Late rectal complication rate was also increased without change of survival when summation of external midline dose and ICR point A dose were more than 70 Gy. Conclusions: In treating stage Ib carcinoma of uterine cervix with HDR-ICR, using 3 Gy per fraction scheme, it is crucial to keep the rectal dose not more than 70 Gy to minimize late rectal complications without compromising the survival rate. To achieve this prescription, an appropriate midline shielding during external radiation is needed

The role of magnetic resonance imaging in the diagnosis of uterine cervical carcinoma  

International Nuclear Information System (INIS)

One hundred and thirteen magnetic resonance (MR) images of the gynecologic organs, which were available after the introduction of 0.1 Tesla Asahi Mark J MR-CT unit in 1983, were reviewed retrospectively. Sagittal and coronal MR images provided useful information on tumor invasion. Myoma had lower signal intensity on the T1-weighted images than the normal uterine tissues and carcinomatous lesions, making it easy to differentiate myoma from cancer. Regarding the presence or absence of tumor invasion to the pelvic wall, MR imaging concurred well with physical findings (87 %), as compared with X-ray CT (77 %). MR imaging seemed to have a great potential in diagnosing recurrence of the pelvic wall and metastasis to the abdominal lymph nodes that are difficult to palpate or inspect. (Namekawa, K.)

Amplification of CyclinL1 in uterine cervical carcinoma has prognostic implications.  

Science.gov (United States)

The chromosomal 3q25.31 region was consistently amplified in primary cancer of cervix (CACX). CyclinL1 is a candidate gene of this region and already have been implicated as an oncogene in head and neck cancers. In this study, we aimed to investigate the involvement of CyclinL1 in cervical carcinogenesis and for this purpose its copy number variation (CNV) was studied in 23 cervical intraepithelial neoplasia (CIN) and 110 CACX samples. In CIN lesions CyclinL1 was not amplified; however, the amplification frequency was 16% (9/56) in stage I/II tumors which remained comparable during subsequent stages of tumorigenesis. This implied association of CyclinL1 amplification with development of early invasiveness. Quantitation of mRNA expression revealed 2.6?±?1.53-fold overexpression of this gene in primary CACX. The amplification/copy number gain of CyclinL1 and its mRNA profile were concordant, in tumors. Immunohistochemical (IHC) analysis in primary CACX, cell lines: SiHa and HeLa revealed intense nuclear expression of cyclinL1, which was further confirmed by Western blot in the cell lines. However 47% (7/15) CACX samples expressed high/intermediate level of cyclin L1. Kaplan-Meier survival analysis indicated CyclinL1 amplification as a determinant of poor patient outcome. Tumor radio-resistance developed as a consequence of CyclinL1 amplification. Cox multivariate analysis revealed that multiparous (?5) CACX patients with amplified CyclinL1 locus along with advanced tumor stage (III/IV) had worst prognosis. Our data suggest importance of CyclinL1 in cervical carcinogenesis with its associated pathways viz: pre-mRNA splicing, cell-cycle regulation (G?/G? and G?/M) being potential targets of therapeutic interventions in CACX.

A case report with typical acute radiation cystitis by postoperative external irradiation to uterine cervical cancer  

International Nuclear Information System (INIS)

A patient with stage IIb cervical cancer who was treated with radical operation and postoperative external irradiation suffered from typical severe acute radiation cystitis at the radiation dose of 4200 rads. This complication is rare at present. Even though this complication is rare but cannot be completely ruled out, periodic urinalysis is necessary during radiation therapy. It is important to diagnose this complication and stop the radiotherapy as soon as possible. As adrenal cortical hormone is thought to be effective, the administration of it should be recommended.

Cytotoxic effect and radiation enhancement of artemisinin in uterine cervical carcinoma cell line HeLa  

International Nuclear Information System (INIS)

Objective: To investigate cytotoxic and radiosensitizing effect of Artemisinin on cervical carcinoma cell line HeLa. Methods: In order to measure the optimized effective time, cytotoxic effect of Artemisinin on HeLa cell line was investigated with MTT assay. The radiosensitization effect of different doses and different treatment duration of Artemisinin on HeLa cell line were evaluated by MTT test, the SER is 1.17 and radiosensitizing effect was measured with multi-target single hit model through SER of HeLa cell. Cell cycles in different groups were calculated by flow cytometry. Results: The 50% inhibition concentration of Artemisinin interacted with HeLa cells for 24 h is 600.19 nmol/ml, and for 48 h is 160.71 nmol/ml. The HeLa cells'surival ratio is 93.51%, 91.87%, and 87.28% after adding Atemisinin of 110.69 nmol/ml and 1 Gy radiation exposure. There are three groups: the chemotherapy only group, the radiotherapy only group and the combination group. The result of the cell cycles showed that cells in G2/M period decreased in the combination group. Conclusion: Artemisinin has radiosensitization effect on cervical carcinoma HeLa cells, whichshows dose and time dependent. Artemisinin can inhibit the G2/M block by ionizing radiation. (authors)

The role of endorectal ultrasonography in the follow-up evaluation of the uterine cervical carcinomas in intra-arterial cisplatin chemotherapy  

Energy Technology Data Exchange (ETDEWEB)

Intra-arterial cisplatin infusion chemotherapy delivers higher concentration of this therapeutic agent to the limited area of cervical carcinoma. We evaluated the role of endorectal ultrasonography (ERUS) in the analysis of the tumor response to this chemotherapy. ERUS was done in 20 patients of cervical carcinomas limited to the pelvis by rotating the 5 MHz linear array transducer along the reference sagittal plane in the middle of uterine cervix and vagina. We examined and compared the change of tumor size and morphology on ERUS, before, during and after intra-arterial cisplatin (50 mg/m{sup 2}) chemotherapy through internal iliac artery near uterine arterial branching. Colposcopy and radical hysterectomy with pelvic lymphadenectomy were performed in all patients, and ERUS findings were compared with those findings. ERUS correlated well with surgery in the estimation of preoperative tumor size and morphology. Tumor reduction rate on ERUS (100- the largest area of the preoperative tumor/the largest area of the initial tumor) was as follows: more than 75% decrease of the original size in 3 patients, 75%-50% in 6 patients, 50%- 25% in 8 patients, and less than 25% in 3 patients. Hyperechoic reflecting areas were noted in 4 patients, which corresponded to gaseous necrosis on postoperative pathology. ERUS is helpful to evaluate the morphologic change of cervical carcinoma limited to the pelvis in intra-arterial cisplatin chemotherapy.

Knowledge, attitudes and practices on cervical cytology-uterine in women from sincelejo and Cartagena, colombia  

Directory of Open Access Journals (Sweden)

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. Existe la necesidad de identificar los factores que influyen en ello, por tantoes importante investigar el nivel de conocimiento de las mujeres sobre la prueba detamizaje, su actitud frente a la misma y sus prácticas relacionadas. Se realizó encuestaa 505 mujeres entre 13 y 60 años edad, que habían tenido vida sexual, residentes en lasciudades de Cartagena y Sincelejo (Colombia. Los resultados revelan que prácticamentetodas las mujeres tienen conocimientos sobre citología cérvico-uterina. El 94.5% delas mujeres se la han realizado por lo menos una vez. Este porcentaje es mayor en elrango de 40 a 60 años donde alcanza el 99%, y en las de menor edad este porcentajedisminuye. Al definir su utilidad: solo el 73.8% respondió de manera acertada. El 50%refieren aspectos desagradables en relación con la toma de la citología, como el miedoy el temor a un diagnóstico de cáncer y el olvido es el principal factor para no reclamarlos resultados. Estos datos demuestran que el porcentaje de mujeres con vida sexualque desconocen la utilidad de la citología o nunca se la han practicado es mínimo, locual permite concluir que la ineficacia de los programas de tamizaje para disminuir lascifras de cáncer de cérvix en nuestro medio depende de otros factores que deben serevaluados.

Bovine uterine, cervical and ovarian cytosol estrogen and progesterone receptor concentrations in cystic ovarian disease.  

Science.gov (United States)

Bovine cytosol estrogen (ERC) and progesterone receptor (PRC) concentrations were measured simultaneously in various regions of the uterus and in ovarian stromal tissue in cows with cystic ovarian disease (follicular cysts), and the concentrations compared with those in animals with normal cycles. In cystic ovarian disease, ERC concentrations in endometrium (550 fmol/mg cytosol protein (c.p.)) and in myometrium (405) were significantly higher than in control animals. Very high PRC contents were measured in the endometrium (3115) and myometrium (2761) of cows with cystic ovarian disease. In control animals, PRC concentrations in the endometrium and myometrium were significantly lower than in diseased animals. No statistical differences were observed in ERC or PRC contents between the endometrium and the myometrium in cows with cystic ovarian disease. ERC and PRC concentrations in the uterine cervix and ovaries were low compared to those detected in the uterus. Bovine serum estradiol-17 beta concentrations were higher (p cows with cystic ovarian disease than in control animals in postpartum anestrus or during the normal estrous cycle. Serum sex hormone-binding globulin (SHBG) concentrations were of the same magnitude as in control cows during their estrous cycles. These findings show that long standing low endogenous progesterone and elevated estradiol concentrations in serum are associated with elevated ERC and PRC concentrations in bovine uterus.

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.

Preoperative PET/CT FDG standardized uptake value of pelvic lymph nodes as a significant prognostic factor in patients with uterine cervical cancer  

International Nuclear Information System (INIS)

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.)

Image-Guided Stereotactic Body Radiation Therapy in Patients With Isolated Para-Aortic Lymph Node Metastases From Uterine Cervical and Corpus Cancer  

International Nuclear Information System (INIS)

Purpose: The aims of this study were to evaluate the role of stereotactic body radiation therapy (SBRT) as a local treatment for isolated para-aortic lymph node (PALN) metastases originating from uterine cervical and corpus cancer. Methods and Materials: We retrospectively enrolled 30 patients with isolated PALN metastases originating from uterine cervical and corpus cancer who had received SBRT using the CyberKnife (CK). All patients were shown to have isolated PALN metastases by computed tomography (CT) and/or positron emission tomography (PET)-CT. The overall survival (OS), local control (LC) rate, and disease progression-free survival (DPFS) rate were calculated according to the Kaplan-Meier method. Comparison between prognosis groups was performed using log-rank analysis. Toxicities were also evaluated. Results: The 4-year OS rate was 50.1%, and the median survival time was not reached. The OS rate among symptomatic patients was significantly lower than that among asymptomatic patients (p = 0.002). The 4-year actuarial LC rate was 67.4%. Patients with a planning target volume of ?17 ml had significantly higher LC rates (p = 0.009). The 4-year DPFS rate was 45.0%, and the median time to disease progression was 32 months. Small planning target volume was a favorable prognostic factor (p = 0.043). Grade 3 or 4 complications requiring hospitalization were reported in 1 patient at 20 months after SBRT. Conclusion: The OS and LS rates were promising, and the incidencS rates were promising, and the incidence of toxicities was low. Use of SBRT with the CyberKnife is an effective modality for treating isolated PALN metastases in patients with uterine cervical and corpus cancer.

Interfractional change of high-risk CTV D90 during image-guided brachytherapy for uterine cervical cancer  

International Nuclear Information System (INIS)

The purpose of this study was to evaluate interfractional changes of the minimum dose delivered to 90% of the high-risk clinical target volume (HR-CTV D90) and D2cc of the bladder and rectum during brachytherapy for uterine cervical cancer patients. A total of 52 patients received external beam radiotherapy and high-dose-rate intracavitary brachytherapy (ICBT). For each of four ICBT applications, a pelvic CT scan was performed and the HR-CTV was delineated. Retrospectively, these patients were divided into two groups: (1) the standard dose group with 6 Gy to point A in each ICBT, and (2) the adaptive dose group with a modified dose to point A to cover the HR-CTV with the 6-Gy isodose line as much as possible. The HR-CTV D90 was assessed in every session, and analyzed as interfractional changes. In the standard dose group, the interfractional changes of the HR-CTV D90 showed a linear increase from the first to the third of the four ICBT (average 6.1, 6.6, 7.0 and 7.1 Gy, respectively). In contrast, those of the adaptive dose group remained almost constant (average 7.2, 7.2, 7.3 and 7.4 Gy, respectively). Especially, in the case of a large HR-CTV volume (?35 cm3) at first ICBT, the total HR-CTV D90 of the adaptive dose group with brachytherapy was significantly higher than that of the standard dose group. There were no significant differences in total D2cc in bladder and rectum between the two groups. Image-guided adaptive brachytherapy based on interfractional tumor volume change improves the dose to the HR-CTV while keeping rectal and bladder doses within acceptable levels. (author)

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)

Reporting radiotherapeutic complications in patients with uterine cervical cancer. The importance of latency and classification system  

DEFF Research Database (Denmark)

Radiotherapeutic morbidity is reported according to our own system (AADK) and the Franco-Italian glossary (FI) in 442 patients with cervical cancer FIGO stage IIB (139), IIIA (10), IIIB (221), and IVA (72). The AADK system records each symptom, date of appearance, the required therapy, and its initial date. FI describes the maximal damage in 4 grades. Actuarial estimates of moderate or worse complications in the rectosigmoideum differed significantly in relation to stage, while frequencies did not differ. Frequencies were up to 25% lower than the actuarial estimates. Moderate AADK complications in the rectosigmoideum occurred from 1 to more than 24 months in 42% of stage IIIB patients finally developing severe FI complications, and during more than 2 years in 24% of the patients dying from rectosigmoid complications. An analysis of the probability of being alive without moderate or worse AADK complications indicated that survival and complications were unrelated. It is concluded that, with any classification system for reporting morbidity, each symptom and required therapy used in the definition of each complication grade and the date of appearance should be registered regularly to allow (1) reporting of the real risk of organ damage, (2) rescoring of complication grades, (3) separation of early and late morbidity, and (4) reporting of actuarial estimates. If these minimum requirements are met, underestimation of morbidity is avoided.

Gastrointestinal tract complications following radiotherapy of uterine cervical cancer: past and present  

Energy Technology Data Exchange (ETDEWEB)

A retrospective analysis of the gastrointestinal tract complications in 298 patients with cervical cancer treated with radiotherapy at the State University of New York at Buffalo and Albert Einstein College of Medicine affiliated hospitals was carried out. Fifty-two patients had pretreatment surgical staging (39 transperitoneal and 13 extraperitoneal). Twenty-four percent had varying degrees of radiation sickness. They all responded to conservative therapy. Seven percent developed Stage I radiation proctitis. In the clinical staging group late complications consisted of: Three small bowel injuries, 4% persistent Stage I, 3% Stage III, and one patient with Stage II radiation proctitis. Among 39 patients who had transperitoneal surgical staging, two small bowel injuries, one case of gastric ulcer, and three cases of radiation proctitis were encountered. Only one of 13 patients who had extraperitoneal surgical staging developed intestino-vesico-vaginal fistula. A literature search was conducted, and prophylactic and therapeutic measures are discussed. The importance of careful selection of patients for radiotherapy and recognition of high risk clinical factors is reemphasized.

The Results of Curative Radiation Therapy for 49 Patients of the Uterine Cervical Carcinomas  

International Nuclear Information System (INIS)

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

Multi-purpose horizontal transit table for influential factors in dose distribution of brachytherapy in moderately advanced and advanced uterine cervical cancer  

International Nuclear Information System (INIS)

Objective: The factors influencing the dose distribution of intracavitary brachytherapy for moderately advanced and advanced uterine cervical cancer was studied. Methods: Ninty-five patients with cervical cancer II-III b who received radical radiation therapy in our department from Aug, 2004 to Nov,2005, were treated with after-loading brachytherapy using, first, the self-designed 'Mutipurpose Horizontal Transit Table (MPHTT) for locating and treatment before the intracavitary brachytherapy proper. The deviation of isodose curve based on A-B reference system, and the dose of deviation was defined by measuring in a practical standard phantom. Results: There were significant influence on the deviation of isodose curve in pathology and para-metrial infiltration of cervical cancer and operating skill, but negative to clinical stage. The degree of deviation of isodose curve could not be lowered with the increase in sessions of' intracavitary brachytherapy. Conclusions: It is necessary to perform the locating, by use of mphtt, before the proper brachytherapy for patients with cervical cancer, not only for the identification of the deviation of isodose curve, but also to provide the evidence for revising the plan for dose adjustment of conformal radiation therapy in the pelvic cavity.

Therapeutic comparison of uterine artery chemoembolization with internal iliac anterior trunk arterial chemotherapy performed before radical hysterectomy in patients with stages I b2-II a cervical cancer  

International Nuclear Information System (INIS)

Objective: To compare the short-term and long-term therapeutic response of uterine artery chemoembolization with internal iliac anterior trunk arterial chemotherapy performed before radical hysterectomy in patients with stages I b2-II a cervical cancer. Methods: One hundred and fifty-one patients with stages I b2-II a cervical cancer were treated with preoperative intra-arterial chemotherapy before radical hysterectomy was carried out. Patients in study group (n = 113) received uterine artery chemoembolization (UACE), while patients control group(n = 38) received internal iliac anterior trunk arterial chemotherapy. Radical hysterectomy was carried out in all patients within 2-4 weeks after UACE or chemotherapy. The tumor size was measured before and after the procedure,and the survival rate at 2 and 5 years after treatment was calculated. Results: The mean maximum diameter of the tumors was (4.58 ± 0.37) cm before interventional therapy, and it was (2.11 ± 0.24) cm in two weeks after interventional therapy. The complete response rate of study group and control group was 31.9% and 21.1% respectively. The total effective rate of study group and control group was 94.7% (107/113) and 76.3% (29/38) respectively. The effective rate of study group two weeks after therapy was significantly higher than that of control group. No surgical margin infiltration was observed in both groups. Pathological findings in study group included vascular invasion around surgical margin (n =lar invasion around surgical margin (n = 3), parametrial invasion (n = 5) and pelvic lymph node metastasis (n = 6), while in control group vascular invasion around surgical margin, parametrial invasion and pelvic lymph node metastasis were found in one, two and one cases respectively. The two-year and five-year survival rate in study group were 80.9% (68/84) and 73.4% (47/64) respectively, while the two-year and five-year survival rate in control group were 81.3% (26/32) and 75.0% (18/24) respectively. No significant difference in survival rate existed between two groups. Conclusion: Uterine artery chemoembolization can markedly reduce the volume of cervical cancer,which is very helpful for surgical resection. The therapeutic effectiveness of UACE is superior to internal iliac anterior trunk arterial chemotherapy, therefore, UACE should be regarded as neo-adjuvant intra-arterial chemotherapy of first choice for patients with stages I b2-II a cervical cancer.

A consensus-based guideline defining the clinical target volume for pelvic lymph nodes in external beam radiotherapy for uterine cervical cancer  

International Nuclear Information System (INIS)

The objective of this study was to develop a consensus-based guideline as well as an atlas defining pelvic nodal clinical target volumes in external beam radiotherapy for uterine cervical cancer. A working subgroup to establish the consensus-based guideline on clinical target volumes for uterine cervical cancer was formulated by the Radiation Therapy Study Group of the Japan Clinical Oncology Group in July 2008. The working subgroup consisted of seven radiation oncologists. The process resulting in the consensus included a comparison of contouring on CT images among the members, reviewing of published textbooks and the relevant literature and a distribution analysis of metastatic nodes on computed tomography/magnetic resonance imaging of actual patients. The working subgroup defined the pelvic nodal clinical target volumes for cervical cancer and developed an associated atlas. As a basic criterion, the lymph node clinical target volume was defined as the area encompassed by a 7 mm margin around the applicable pelvic vessels. Modifications were made in each nodal area to cover adjacent adipose tissues at risk of microscopic nodal metastases. Although the bones and muscles were excluded, the bowel was not routinely excluded in the definition. Each of the following pelvic node regions was defined: common iliac, external iliac, internal iliac, obturator and presacral. Anatomical structures bordering each lymph node region were defined for six directions; anterior, posteriined for six directions; anterior, posterior, lateral, medial, cranial and caudal. Drafts of the definition and the atlas were reviewed by members of the JCOG Gynecologic Cancer Study Group (GCSG). We developed a consensus-based guideline defining the pelvic node clinical target volumes that included an atlas. The guideline will be continuously updated to reflect the ongoing changes in the field. (author)

Expression of indoleamine 2, 3-dioxygenase and the recruitment of Foxp3-expressing regulatory T cells in the development and progression of uterine cervical cancer.  

Science.gov (United States)

Foxp3(+) CD4(+)CD25(+) regulatory T (Treg) cells and immunoregulatory enzyme indoleamine 2,3-dioxygenase (IDO) play an important role in immunoregulation. Accumulating evidence shows that IDO and Treg cells have potent regulatory properties for immune escape in cancer. To evaluate the expression of IDO and the localization of Foxp3(+) Treg cells in the development and progression of uterine cervical cancer, IDO expression and Foxp3(+) Treg cells in the primary and metastatic lesions were studied using immunohistochemistry. IDO expression in tumor cells appeared in cervical intraepithelial neoplasia (CIN)-3 of the uterine cervix and marked expression in microinvasive cancer cells was observed. Interestingly, IDO expression in invasive cancer was confined to the cancer cells at the invasive front. Moreover, antigen-presenting cells (APC) at the invasive front in primary and metastatic lesions were also expressing IDO. Stromal Foxp3(+) Treg cells appeared in CIN-3 and increased in microinvasive and invasive cancer. Intraepithelial Foxp3(+) Treg cells were restricted within microinvasive and invasive cancer. No significant differences in the proportion of Foxp3(+)/CD4(+) in the stroma or epithelium, or between non-metastatic and metastatic invasive cancers, were observed in primary lesions of cervical cancer, while there was a significant increase (P < 0.005) in the proportion of Foxp3(+)/CD4(+) in metastatic lymph nodes compared with non-metastatic lymph nodes. Some of the Foxp3(+) Treg cells in metastatic lymph nodes contacted the IDO(+) APC. IDO expression at the invasive front of cancer cells and APC, and the localization of Foxp3(+) Treg cells in front of cancer tissues, may create a network between IDO and Treg for the induction of immune escape.

EVALUATION OF P16INK4A PROTEIN AS A BIOMARKER FOR CERVICAL INTRAEPITHELIAL NEOPLASIA AND SQUAMOUS CELL CARCINOMA OF THE UTERINE CERVIX  

Directory of Open Access Journals (Sweden)

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.

Uterine neoplasms: MR imaging  

International Nuclear Information System (INIS)

Magnetic resonance (MR) studies were performed on 20 healthy volunteers and 41 patients with proved cervical and uterine neoplasms. MR imaging demonstrated normal uterine landmarks in all patients. On T2-weighted images, the normal uterine wall could be differentiated into three distinct layers: a central high-intensity zone, a junctional low-intensity band, and a peripheral medium-intensity area. While most of the normal cervices had only two distinct zones (central high-intensity zone and peripheral low-intensity zone), a small percentage had three layers of signal intensity, similar to the uterine body. Primary cervical and uterine neoplasms could be identified on MR images. In 18 of 22 patients with proved carcinoma, a mass with a signal intensity higher than that of normal cervical lips was seen on T2-weighted images. Endometrial carcinoma was most often identified as expansion of the central high-intensity area; discrete tumor nodules were visible in nine of 15 patients. Mixed mullerian sarcoma appeared as a large pelvic mass with complete obliteration of normal uterine landmarks. MR imaging delineates primary cervical and endometrial carcinoma better than computed tomography does

Dose to the non-involved uterine corpus with MRI guided brachytherapy in locally advanced cervical cancer  

International Nuclear Information System (INIS)

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

p16 INK4a and Ki67 expression in normal, dysplastic and neoplastic uterine cervical epithelium and human papillomavirus (HPV) infection.  

Science.gov (United States)

Cellular cycle proteins like the p16(INK4a) and the Ki67 proliferation nuclear antigen have been used as oncogenicity cellular markers. The E6 and E7 oncoproteins interact with tumor suppressor genes p53 and pRb, culminating with the p16(INK4a) overexpression. The objective of this study was to evaluate the presence of HPV-DNA in 174 cervical biopsies and correlate the different histological grades with the p16(INK4a) and Ki67 immunohistochemical expression (IHC). A cross-sectional study that enrolled a total of 174 women who underwent uterine cervical biopsies between February 2003 and December 2006, in southern Brazil, was performed. Cervical smear samples were analyzed for the presence of HPV-DNA through polymerase chain reaction (PCR), and biopsy samples were examined for p16(INK4A) and Ki67 expression through IHC techniques. The presence of HPV-DNA was observed in 89% of the tested patients, among which 52% were positive for high-risk (HR) viral types [16, 18 and 31]. Regarding p16(INK4a), an expression of 69% was observed, being expressed in 100% of the high-grade squamous lesions (HSIL) and HR-HPV-DNA positives. Ki67 expression was associated with the lesion grade, being more expressive in the most severe lesions (p<0.001). p16(INK4A) and Ki67 markers coexpression was present in 86% of the samples (p<0.001), being 100% among those positive to HR-HPV-DNA with HSIL (p<0.001). The results suggest an association between the presence of HR-HPV infection and the p16(INK4a) and Ki67 expression and which is even stronger among women with HSIL. PMID:24793773

Does supplementing dairy cows with ?-carotene during the dry period affect postpartum ovarian activity, progesterone, and cervical and uterine involution?  

Science.gov (United States)

?-carotene is the main natural precursor of vitamin A and plays an important role in reproductive efficiency and immune function in dairy cows. The objective of this study was to investigate whether a supplement of ?-carotene given during the dry period is able to 1) increase blood concentrations of ?-carotene postpartum, 2) improve ovarian function and progesterone production, and 3) enhance uterine involution and uterine health. This study was conducted using 40 Holstein cows. On the day of drying-off, cows were allocated to one of two dietary treatments: control diet (C, n = 20) or control diet plus 1g/d ?-carotene (BC, n = 20). The ?-carotene supplement was given individually to the cows until calving. Blood samples were obtained regularly before and after calving from the cows to measure the concentrations of ?-carotene. The diameters of the cervix and uterine horns were measured regularly using ultrasonography. Endometrial cytology samples were acquired from the cervix and uterus to determine uterine health. Milk samples were obtained three times per week for progesterone assay. Additional blood samples were taken on the day of calving, 7 and 21 days postpartum to determine the plasma concentrations of amino acids. Blood concentrations of ?-carotene were not different before the start of the experiment (C, 3.03 ± 0.22 mg/L vs BC, 3.12 ± 0.22 mg/L, P > 0.05). Blood concentrations of ?-carotene in the BC group peaked (7.45 ± 0.24 mg/L) 1 month after drying-off while the concentrations in the C group remained constant. ?-carotene concentrations then decreased in both groups. The difference in blood concentrations of ?-carotene between groups became significant 2 weeks after the start of the supplement until 2 weeks postpartum. There was no significant difference in the interval from calving to ovulation between groups (C, 27.8 ± 3.46 d vs BC, 35.8 ± 3.55 d, P > 0.05). The dietary supplement of ?-carotene during the dry period had no effect on ovarian activity, progesterone production, cervix and uterine horn diameters. Plasma concentrations of hydroxyproline in the BC group were higher than in the C group on day 21 postpartum (BC, 20.8 ± 1.33 ?mol/L vs C, 15.0 ± 1.33 ?mol/L; P involution may have been more complete and that uterine inflammation may have been reduced in cows which received the ?-carotene compared to controls.

Human Papilloma Virus Early Proteins E6 (HPV16/18-E6) and the Cell Cycle Marker P16 (INK4a) are Useful Prognostic Markers in Uterine Cervical Carcinomas in Qassim Region- Saudi Arabia.  

Science.gov (United States)

Cervical cancer is a common and an important public health problem for adult women in developing countries. In contrast, cervical cancer incidence is low in Saudi Arabia. High-risk types of human papilloma viruses (HPV16 and HPV18) are the most significant risk factors for cervical cancer. HPV16/18-E6 oncoprotein is associated with HPV etiology, viral persistence and epithelial transformation. Cell cycle protein p16 INK4a (p16) plays an important role in the pathophysiology of cervical carcinomas. The aims of this study were to investigate the expression of HPV16/18-E6 and p16 in uterine cervical carcinomas in Qassim Region - Saudi Arabia, and to relate the results to the established clinicopathological prognostic parameters (age of the patient, educational level, birth control methods, number of pregnancy, smoking status, degree of histological differentiation, clinical stage, and lymph node metastasis) The study included 40 specimens of uterine cervical squamous cell carcinomas diagnosed and confirmed by biopsy. Histopathological classification of cervical tumors cases was performed according to the International Federation of Gynecology and Obstetrics (FIGO). Immunohistochemical analysis for HPV16/18-E6 and p16 were carried out on formalin-fixed paraffin-embedded sections of cervical tissues using avidin-biotin peroxidase method. There was a significant statistical correlation between HPV16/18-E6 expression in cervical carcinoma and nationality, smoking status and size of the tumor. HPV16/18-E6 oncoprotein expression in normal lymphocytes and endothelial cells in the tumor tissues and the adjacent normal cervical tissues suggest the possibility that HPV infection might spread to other organs through blood circulation. P16 expression has been correlated with high grade, stage of cervical SCC and HPV16/18-E6 expression. The current study supports the critical function of p16 and HPV16/18-E6 as specific markers for cervical carcinoma. However the potential for usage of p16 and HPV16/18-E6 as prognostic markers will require detailed follow data for a larger group of patients. PMID:24925218

Studies on combined effect of irradiation with CDDP and BLM in cultured cells from uterine cervical cancer  

International Nuclear Information System (INIS)

The purpose is to examine the combined effect of irradiation with anticancer drugs on uterine cancer, SKG-IIIb cells, cultured from squamous cell carcinoma of uterine cervix, were used in this study. Anticancer drugs were CDDP 1 ?g/ml, BLM 10 ?g/ml, and the radiation was 60Co 0.5 Gy. The results were as follows: The growth of cells was the most strongly suppressed by the exposure to radiation after CDDP administration. By the exposure to radiation after anticancer drugs administration, the morphorogic damage of cells was revealed both by a light microscope and a scanning electron microscope. Flow cytometric measurement revealed that anticancer drugs changed DNA distributions of cells: the accumulation of exposed cells in S phase was showed and the cell cycle progression was delayed. DNA histograms showed no accumulation of cells in G2+M phase that were most effective phase to irradiation in 24 hours after anticancer drugs administration, but partial synchronization in G2+M phase in 48 hours after BLM administration. These results indicate that the combined therapy of anticancer drugs and irradiation on uterine cancer is effective and timely irradiation will be more effective. (author)

Adenocarcinoma involving the uterine cervix: magnetic resonance imaging findings in tumours of endometrial, compared with cervical, origin  

Energy Technology Data Exchange (ETDEWEB)

To determine the distinctive magnetic resonance imaging (MRI) features of cervical and endometrial adenocarcinoma that present clinically as cervical mass. From 1999 to 2002, 56 patients with adenocarcinoma on the initial biopsy of a cervical mass underwent MRI at our institution. Of these, 42 had a visible mass on MRI. Pathology review of all available tissue was the reference standard. A site of origin was determined by the pathologist in 38 of the 42 patients, and these were the cases evaluated; of these patients, 32 cases had adenocarcinoma and 6 had adenosquamous cancers. Findings were significantly more prevalent in patients with adenocarcinomas of endometrial, compared with cervical, origin for endometrial thickening (11 [73%] and 3 [13%], respectively; P = 0.0003), endometrial mass (11 [73%] and 1 [4%], respectively; P < 0.0001), endometrial cavity expansion by a mass (9 [60%] and 2 [9%], respectively; P = 0.001), and invasion of myometrium from endometrium (9 [60%] and 0, respectively; P < 0.0001). Adenocarcinomas of the endometrium that involve the cervix have MRI features that help distinguish them from primary adenocarcinomas of the cervix. (author)

Detection of apoptosis and expression of apoptosis-associated proteins as early predictors of prognosis after irradiation therapy in stage IIIb uterine cervical cancer  

International Nuclear Information System (INIS)

We investigated the proportion of apoptotic cells and the expression of apoptosis-associated proteins after the delivery of the first week of irradiation for stage IIIb uterine cervical cancer. Thirty patients with stage IIIb squamous cell carcinoma of the uterine cervix who received only irradiation therapy were registered in this study. Specimens were obtained before irradiation therapy and at the end of the first week of irradiation. The apoptotic index (AI) of each tissue specimen was calculated by counting the apoptotic cells and expressed as a percentage. Immunohistochemical evaluation for apoptosis-related proteins, p53, Bcl-2, Bax, caspase-1 and caspase-3 was also performed. The AI was 0.8±0.9% (mean±SD) before irradiation and 1.7±1.3% at the end of the first week of irradiation. We observed that the patients who survived more than 5 years had AI levels of 2.1±1.3% at the end of their first week of therapy. This rate was significantly higher than the rate of 1.1±0.8% (P=0.02) of the patients who died within 5 years. When the cut-off value of the AI was set at 1.7%, the sensitivity, specificity, positive predictive value, and negative predictive value for the prediction of patients' prognosis after irradiation therapy were 73.4%, 72.4%, 82.4%, and 61.5%, respectively. In 17 of the AI-positive cases, expressions of Bax (P=0.006), caspase-1 (P=0.045), and caspase-3 (P=0.013) at the end of the first week were significantly higher than before irradiation. The higher than before irradiation. The proportion of apoptotic cells and the expression of apoptosis-associated proteins, Bax, caspase-1, and caspase-3, at the end of the first week of irradiation could be useful predictors of the prognosis in stage IIIb squamous cell carcinoma of the uterine cervix treated by irradiation therapy.

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, pourvived 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.)

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 favcess. 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)

Pelvic lymph node invasion in cervical cancer; L`envahissement ganglionnaire pelvien dans les cancers du col uterin  

Energy Technology Data Exchange (ETDEWEB)

Pelvic lymph node invasion is an important prognostic factor for cervical cancer. It is generally accepted that iliac lymph nodes must be treated systematically, but the extent of lymph node dissections is open to discussion. One hundred and eighty two cases of cervical cancer with lymph node invasion were treated at the Institut Curie between 1960 and 1988, by colpophysterectomy with lymph node dissection (168 cases) combined with preoperative brachytherapy and, in some cases, pre- and/or postoperative radiotherapy; in 14 cases, only an exploratory operation was performed. External iliac lymph node invasion was found in 95% of cases, situated in the middle and internal chains. Common iliac lymph node invasion was found in 24% of cases, but was only exceptionally isolated (3%). It is therefore possible, by means of well defined, localized external iliac dissection, with frozen section histological examination, to determine the exact lymph node status. Lumboaortic lymph node invasion was found in 8.2% of cases. The overall survival rate was 49% at 5 years and 40.5% at 10 years. Factors which influence survival are: the cervical volume (p = 0.015), the unilateral or bilateral nature of invasion (p = 0.0015), the number of lymph nodes invaded (two or more than two) (p = 0.0001), capsular rupture (p = 0.0008), lymph node adhesions other than venous (p = 0.0002), common iliac invasion (p 0.0001). On Cox`s model, the principal factors were the number of lymph nodes invaded, adhesion other than venous, common iliac invasion; on the other hand, venous adhesion does not modify the prognosis. The five-year survival rates following external iliac dissections and complete pelvic dissections were not significantly different. Finally, postoperative radiotherapy ensured a higher five-year survival rate than preoperative radiotherapy, but the cervical volume was greater and primary invasion was more frequent in these cases.

Protein p 16INK4A expression in cervical intraepithelial neoplasia and invasive squamous cell carcinoma of uterine cervix  

Directory of Open Access Journals (Sweden)

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.

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)

Unstable chromosome aberrations on peripheral blood lymphocytes from patients with cervical uterine cancer following radiotherapy; Aberracoes cromossomicas instaveis em linfocitos de pacientes com cancer de colo de utero  

Energy Technology Data Exchange (ETDEWEB)

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.

Conclui-se que a queda da mortalidade por câncer do útero não especificado sinaliza uma melhora na precisão do diagnóstico clínico e na qualidade do preenchimento do atestado de óbito, e indica aumento de cobertura do teste de Papanicolaou.Uterine cervical cancer shows a higher incidence in some Brazilian cities. It is a common cause of death in women from developing countries, despite the longstanding availability of an effective screening test, the Pap smear. This study aimed to evaluate the temporal trends of crude, age-adjusted, and age-specific mortality rates from cervical cancer, endometrial cancer, and cancer of the uterus not otherwise specified (NOS in the city of São Paulo from 1980 to 1999. Results showed a slight reduction in cervical cancer rates, a decrease in NOS uterine cancer rates, and an increase in endometrial cancer mortality rates. The fall in mortality from NOS uterine cancer indicates an improvement in diagnostic accuracy and quality of information on death certificates and may point to an increase in coverage of cervical cancer screening using the Pap smear.

Results of radiotherapy for stage III uterine cervical carcinomas and preliminary study of combined radiotherapy and transarterial infusion chemotherapy  

International Nuclear Information System (INIS)

This is a retrospective analysis of 55 patients with stage III carcinoma of the uterine cervix treated with radiation from November 1984 through December 1991. Eleven of the patients were treated with radiation and transarterial infusion chemotherapy (TAI), using cis-platinum and pepleomycin. The 3- and 5-year cumulative survival rates for all patients were 61% and 58%, respectively, and the 3-year cumulative survival rate for the group with combined radiation and TAI was 47%. According to initial failure site, the locoregional recurrence rate was 36.8%, and that for para-aortic lymph node metastasis and distant metastasis was 31.6%. The failure pattern was similar between the irradiation only group and the group with combined radiation and TAI. The incidence of intestinal complications of grades 1 and 2 was 20%. Irradiation combined with TAI did not increase the incidence of complications. (author)

Is the adaptive tomography of cervical carcinomas necessary?; La tomotherapie adaptative des carcinomes du col uterin est-elle necessaire?  

Energy Technology Data Exchange (ETDEWEB)

The authors report the study of the macroscopic tumour volume (GTV, gross tumour volume) and its possible repercussion on organs at risk during a tomo-therapy with an additional concomitant centro-pelvic irradiation. Ten women with non-operable cervical carcinomas have been treated by tomo-therapy and chemotherapy. A high-energy conical tomography has been performed before each session. Data obtained from these tomographies have been used in the adaptive therapy module of a tomo-therapy planimetry software. It appears that there is no evidence of significant variations of doses at the level of organs at risk with the use of such software. Short communication

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 denr 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

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 wasrapy. 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)

Sensory and motor dysfunction assessed by anorectal manometry in uterine cervical carcinoma patients with radiation-induced late rectal complication  

International Nuclear Information System (INIS)

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 functiovoir 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

[Clinical recommendations for diagnosing, treatment and monitoring of patients with uterine cervical cancer -- Croatian Oncology Society and Croatian Society for Gynecology and Obstetrics as Croatian Medical Association units and Croatian Society of Gynecological Oncology].  

Science.gov (United States)

Cervical cancer, in comparison with other gynecological malignancies, mainly affects younger women. It can be prevented trough educational programs, screening and early detection. It also can be efficiently treated when it appears. Treatment modalities include surgery, chemotherapy and radiotherapy, according to the stage of the disease and patient condition. Treatment decisions should be made after multidisciplinary team discussion. Due to the significance of this disease it is important to define and implement standardized approach for diagnostic, treatment and monitoring algorithm as well. The following text presents the clinical guidelines in order to standardize the procedures and criteria for the diagnosis, management, treatment and monitoring of patients with uterine cervical cancer in the Republic of Croatia.

PET in uterine malignancies  

Directory of Open Access Journals (Sweden)

Full Text Available 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 18FFDG in uterine malignancies (cervical and endometrial cancers as well as uterine sarcomas, underlying its advantages and discussing its limitations. Metabolic and anatomic information given by PET/CT with 18F-FDG could be useful in the evaluation of local and distant disease involvement at the staging, in the detection of disease recurrence, and in the evaluation of the response after chemotherapy and/or radio-therapy.

Spontaneous uterine rupture at 32 weeks of gestation after previous uterine artery embolization.  

Science.gov (United States)

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

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.

Non-randomized confirmatory trial of modified radical hysterectomy for patients with tumor diameter 2 cm or less FIGO Stage IB1 uterine cervical cancer: Japan Clinical Oncology Group Study (JCOG1101).  

Science.gov (United States)

A non-randomized confirmatory trial was started in Japan to evaluate the efficacy of modified radical hysterectomy in patients with tumor diameter 2 cm or less FIGO Stage IB1 uterine cervical cancer, for which the current standard is radical hysterectomy. This study began in January 2013 and a total of 240 patients will be accrued from 37 institutions within 3 years. The primary endpoint is 5-year survival. The secondary endpoints are overall survival, relapse-free survival, local relapse-free survival, percent completion of modified radical hysterectomy, percent local relapse, percent pathological parametrial involvement, days until self-urination and residual urine disappearance, blood loss, operation time, percent post-operative radiation therapy, adverse events and severe adverse events. This trial was registered at the UMIN Clinical Trials Registry as UMIN 000009726 (http://www.umin.ac.jp/ctr/). PMID:25368103

Giant prolactinoma presenting as a skull base tumor with erosion of the cervical vertebrae: pronounced responsiveness to dopamine agonist treatment.  

Science.gov (United States)

Giant prolactinomas are rare and usually associated with symptoms attributable to hypopituitarism and compression of juxtasellar structures such as the cranial nerves of the cavernous sinus and the optic chiasm. Occasionally, they masquerade as skull base tumors with atypical symptoms. We describe a patient who presented with a low-energy trauma in the neck region that led to the initial diagnosis of a large skull base tumor eroding the cervical vertebrae. After stabilizing surgery, the patient responded to dopamine agonist therapy with normalization of serum prolactin levels and pronounced reduction in tumor volume. PMID:25162753

Possible evidence that dehydroepiandrosterone sulfate (DHA-S) stimulates cervical ripening by a membrane-mediated process: Specific binding-sites in plasma membrane from human uterine cervix  

International Nuclear Information System (INIS)

Fetal adrenal steroid, dehydroepiandrosterone sulfate (DHA-S) is well known to promote cervical ripening in late pregnancy. The presence of sites specifically binding the DHA-S in plasma membrane was studied in human cervical fibroblasts prepared from pregnant uterus. The fibroblasts were incubated with 3H DHA-S and then fractionated into plasma membranes, cytosol, nuclei, and other organella debris. The specific activity of 3H-count in the plasma membrane fraction was enriched ? 7-fold compared with the whole homogenate. When the isolated plasma membrane preparations from the fibroblasts were exposed to 3H DHA-S, the binding showed saturation kinetics; an apparent equilibrium dissociation constant (Kd) of 12 nM, and the binding capacity (Bmax) of 1.25 pmol/mg protein. The present results suggest that DHA is bound to and recognized by components in plasma membrane, and may exert its action on cervical ripening through the membrane-mediated processes

Uterine arterial embolization to treat uterine leiomyoma  

International Nuclear Information System (INIS)

Objective: To assess the clinical effects of uterine arterial embolization on uterine leiomyoma. Methods: The authors treated 21 patients with uterine leiomyoma by Seldinger's uterine arterial embolization. The 4.0 F Cobra catheter was laced into the double uterine arteries with Polyvinyl Alcohol Foam (PVA) particles as the embolization. At 3 and 6 months postoperatively, the authors investigated the effects of the embolization. Results: After uterine arterial embolization, the volume of uterine leiomyoma decreased and menorrhagia was under controlled. The symptoms of anemia and oppression were relieved. The physiologic functions of ovary and uterus were preserved completely. Conclusions: Uterine arterial embolization is an effective and less invasive way to treat uterine leiomyoma

MRI appearances of benign uterine disease.  

Science.gov (United States)

Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases. PMID:25017452

Development of uterine neoplasms following radiotherapy for carcinoma of uterine cervix: a clinical evaluation of 47 patients  

International Nuclear Information System (INIS)

Objective: To analysis the characteristics and clinical features of uterine neoplasms developed after radiation therapy for cervical carcinoma. Methods: The clinical data of 47 patients of uterine neoplasm developed following radiotherapy for uterine cervical carcinoma were retrospectively reviewed. Results: The median age on diagnosis of uterine neoplasms was 62 years (range 38-77), and the median latency from the initial therapy to the development of uterine neoplasm was 14 years (range 5-35). Thirty of 47 patients had endometrial carcinoma, of which 3 were uterine papillary serous carcinoma(UPSC). Seventeen of 47 patients had uterine sarcoma, all of which were carcinosarcoma. The distribution by stage, grade, and histology of 30 patients with endometrial carcinoma was: stage Ib, 1 patient; stage Ic, 2 patients; stage II, 6; stage III a, 4; stage III b, 2; stage III c, 11; stage IV, 4; grade 1, 2 patients; grade 2, 9; grade 3 (include 3 UPSC patients), 17; unknown grade, 2; endometriod, 27; UPSC, 3. Seven of 30 patients with en- dometrial carcinoma deleloped recurrence, at median time of 24 months. Their median survival time was 26 m. The overall 3- and 5-year survival rate was 60% and 38%, respectively. Of the 17 patients with uterine sarcoma, the median survival was 10 months. Six patients developed recurrence, at a median time of 9 months, and their median survival was 6 months. The overall 3- and 5-year survival rate was 12% and 0, respectively. Conclnsions: The 12% and 0, respectively. Conclnsions: The main uterine neoplasm developed after radiotherapy for uterine cervical carcinoma is endometrial carcinoma, of which there is a preponderance of high-risk histological subtype and poor prognosis. Most of the uterine sarcoma which occur following radiation therapy for uterine cervical carcinoma is carcinosarcoma and its prognosis is very poor. (authors)

Radiographic and ultrasonographic findings of uterine neoplasms in nine dogs.  

Science.gov (United States)

The records of nine female intact dogs with histologically confirmed uterine tumors were reviewed retrospectively, and the related radiographic and ultrasonographic signs of the lesions detected were recorded. Radiography revealed a soft-tissue opacity between the urinary bladder and colon in six of seven dogs with uterine body and/or cervical tumors, and a soft-tissue opacity in the midventral abdomen in two dogs with uterine horn tumors. Ultrasonography revealed masses in all dogs with uterine body/cervical tumors and could delineate the origin of the mass in one of two dogs with uterine horn tumors. The mass was characterized ultrasonographically as solid in three dogs (all leiomyomas), solid with cystic component in four dogs (two adenocarcinomas, one leiomyoma, and one fibroleiomyoma), and cystic in two (both leiomyomas). Hyperechoic foci in the mass were observed in three dogs. Ultrasonography was a useful method for demonstrating uterine body and/or cervical tumors. However, it was not possible to ascertain sonographically that a mass originated in a uterine horn unless there was associated evidence of uterine horn to which the mass could be traced. The ultrasonographic appearance of uterine tumors was variable, and the type of neoplasm could only be determined by taking biopsies of the mass. PMID:25028432

Increase in Viral Load, Viral Integration, and Gain of Telomerase Genes during Uterine Cervical Carcinogenesis can be Simultaneously Assessed by the HPV 16/18 MLPA-Assay  

OpenAIRE

Oncogenic human papillomavirus (HPV) infection is the most important risk factor in cervical carcinogenesis cases; high viral loads, viral integration into the host genome, and gain of the telomerase-related genes, TERT and TERC, are all factors associated with progression to cancer. A recently developed multiparameter HPV 16/18 multiplex ligation-dependent probe amplification (MLPA) assay, which allows the simultaneous assessment of these factors, was applied to a series of 67 normal and (pr...

Preliminary Experience with Locoregional Intraarterial Chemotherapy of Uterine Cervical or Endometrial Cancer Using the Peripheral Implantable Port System (PIPSTM): A Feasibility Study  

International Nuclear Information System (INIS)

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

Preliminary estimation of treatment effect on uterine cervical squamous cell carcinoma in terms of tumor regression rate. Comparison between chemoradiotherapy and radiotherapy alone  

International Nuclear Information System (INIS)

We preliminarily estimated the treatment effect on cervical cancer in terms of the tumor regression rate (TRR) achieved with chemoradiotherapy and radiotherapy alone. The study included cervical squamous cell carcinomas treated by radiotherapy alone (n=45) or chemoradiotherapy (concurrent once-a-week cisplatin 30 mg/m2, n=13). Tumors were measured three-dimensionally on pre- and mid-treatment magnetic resonance images. TRR was defined as the slope of the exponential regression curve of tumor volume (day-1) on the assumption that tumors regressed exponentially with time. TRR ranged widely (0.004-0.090 day-1) and did not significantly differ between treatment with chemoradiotherapy (median, 0.032 day-1) and with radiotherapy alone (median, 0.024 day-1) (p=0.361). TRR>0.05 day-1 was seen in four chemoradiotherapy tumors (30.8%) and in six radiotherapy-alone tumors (15.0%) (p=0.207), whereas TRR-1 was seen in no chemoradiotherapy tumors (0.0%) and in five radiotherapy-alone tumors (11.1%) (p=0.180). TRR for tumors >5.0 cm in diameter was greater with chemoradiotherapy (n=5) than with radiotherapy alone (n=12) (p=0.065). Although the difference did not reach a statistically significant level, our TRR data suggest that concurrent chemotherapy heightens the radioresponse of large-size cervical cancer. (author)

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  

Energy Technology Data Exchange (ETDEWEB)

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).

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. Surgical treatment (hysterectomy and total laparoscopic radical hysterectomy plus pelvic lymphadenectomy) is the best therapeutic resource in the early cancer stage (IA1, IA2 and IB1). One year ago we star [...] ted laparoscopic surgical treatment in these stages at Hospital IV Huancayo Gynecology Department. 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.

Impact of curie-therapy timing in the treatment of cervical cancer; Impact du timing de la curietherapie dans le traitement du cancer du col uterin  

Energy Technology Data Exchange (ETDEWEB)

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

Three Unique Cases of Uterine Anomaly: Atypical Müllerian Ducts Development  

Directory of Open Access Journals (Sweden)

Full Text Available Uterine anomalies have different types and are classified in different ways. Here, we report three hysterosalpingographically unique cases of uterine anomalies selected from more than 30,000 cases over duration of 40 years. Case 1 is a branching out bicornuate uterus, in which the left uterine horn and cervix branch from the cervical canal. The second case is a unicornuate uterus, in which a fallopian tube without uterine cavity directly branches from this corn. The third case is a cross-shaped bicornuate uterus. Considering the embryologic development of uterus, we concluded that these three cases had abnormalities in different stages of their Müllerian ducts' development

Uterine Lesions  

Directory of Open Access Journals (Sweden)

Full Text Available Transvaginal color and pulsed Doppler ultrasound depicts the endometrium in great details. The texture and thicknessof the endometrium are indicators of endometrial development, while blood flow analysis may be used as a bioassay of the uterine receptivity. This method can non-invasively detect uterine anomalies, endometrial polyps,submucous leiomyomas, intrauterine adhesions and other uterine causes that can lead to poor reproductive performance. Vascularization of the uterine tumors, if used together with analysis of morphology and size, can increase our accuracy in differentiation between uterine sarcoma and leiomyoma. It seems that the multiparameter sonographic approach, which includes morphology and size depicted by transvaginal ultrasonography and color flow imaging withpulsed Doppler analysis of neovascular signals,can help in diagnosis of uterine sarcoma in high-risk groups such as postmenopausal patients with a rapidly enlarging uterus. Therefore, serial measurements are recommended for evaluation of the myometrial density, follow-up of the tumoral growth, and detection of the impedance to blood flow.Only such complex observations can lead to proper diagnosis of these rare tumors with unpredictable prognosis. The application of transvaginal color Doppler to the postmenopausal population for screening of endometrial carcinoma may be a viable option if combined with ovarian screening in the same scan. In this way, the capital costs would be shared, and an oncological preventive medicine for women could be created. The use of this technique could also result in a reduction in dilatation and curettage operations with considerable saving of both the potential risks and economic costs of the operation.

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)  

Energy Technology Data Exchange (ETDEWEB)

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.

Prospective Multi-Institutional Study of Definitive Radiotherapy With High-Dose-Rate Intracavitary Brachytherapy in Patients With Nonbulky (<4-cm) Stage I and II Uterine Cervical Cancer (JAROG0401/JROSG04-2)  

Energy Technology Data Exchange (ETDEWEB)

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.

Extreme cervical elongation  

Directory of Open Access Journals (Sweden)

Full Text Available Uterine prolapse is a condition which has commonly affected women of all times. The problem of genital prolapse and its remedies is described in the oldest medical literature, the Egyptian Papyri. The normal length of the cervix is about 2.5 cm. The vaginal and supravaginal parts are of equal length. The elongation may affect either part of the cervix. The length of the uterocervical canal is measured by introduction of the uterine sound. Cervical elongation plays an important role in deciding the surgical treatment. We had a case of extreme cervical elongation and we faced difficulties during the surgery.

Node-by-node correlation between MR and PET/CT in patients with uterine cervical cancer: diffusion-weighted imaging versus size-based criteria on T2WI  

International Nuclear Information System (INIS)

The purpose of the study was to perform a node-by-node comparison of an ADC-based diagnosis and various size-based criteria on T2-weighted imaging (T2WI) with regard to their correlation with PET/CT findings in patients with uterine cervical cancer. In 163 patients with 339 pelvic lymph nodes (LNs) with short-axis diameter >5 mm, the minimum apparent diffusion coefficient (ADC), mean ADC, short- and long-axis diameters, and ratio of long- to short-axis diameters (L/S ratio) were compared in PET/CT-positive and -negative LNs. On PET/CT, 118 (35%) LNs in 58 patients were positive. The mean value of minimum and mean ADCs, short- and long-axis diameters, and L/S ratio were different in PET/CT-positive (0.6436 x 10-3 mm2/s, 0.756 x 10-3 mm2/s, 10.3 mm, 13.2 mm, 1.32, respectively) and PET/CT-negative LNs (0.8893 x 10-3 mm2/s, 1.019 x 10-3 mm2/s, 7.4 mm, 11.0 mm, 1.49, respectively) (P<0.05). The Az value of the minimum ADC (0.864) was greater than those of mean ADC (0.836), short-axis diameter (0.764), long-axis diameter (0.640) and L/S ratio (0.652) (P<0.05). The sensitivity and accuracy of the minimum ADC (86%, 82%) were greater than those of the short-axis diameter (55%, 74%), long-axis diameter (73%, 58%) and L/S ratio (52%, 66%) (P<0.05). ADC showed superior correlation with PET/CT compared with conventional size-based criteria on T2WI. (orig.)ig.)

Unusual 2-[18F]-fluoro-2-deoxy-D-glucose accumulation induced by postoperative intestinocutaneous fistula in the patient with uterine cervical cancer and SLE.  

Science.gov (United States)

A 47-year-old woman with systemic lupus erythematosus presented with a history of radical hysterectomy and pelvic lymph node dissection for cervical cancer Ia and brachytherapy for vaginal recurrence. Four years later, abnormal hypermetabolic lesion at vaginal vault on FDG-PET/CT was found and confirmed as vaginal recurrence by punch biopsy. So, she underwent anterior pelvic exenteration with urostomy. She underwent colostomy because of colonic fistula 1 week after anterior pelvic exenteration. She had wound problem near the colostomy site. The wound waxed and waned, however, no definite discharge was identified from wound. Three months later after anterior pelvic exenteration, FDG-PET/CT revealed multiple hypermetabolic lesions along the incision line, colostomy site and abdominopelvic lymph nodes. Biopsies of the skin and lymph nodes with FDG accumulation revealed an inflammatory granulation tissue and reactive lymphadenopathy. Definite symptom such as leakage of stool was not identified. One year later, there was no interval change of multiple hypermetabolic lesions on follow-up FDG-PET/CT. There was still wound problem. So, revision of colostomy was done with impression of subtle fistula between skin and colostomy. Multiple hypermetabolic lesions on FDG-PET/CT disappeared after 3 months of repair of colostomy. We reported a case showing high FDG accumulation at wound and paraaortic lymph node on PET/CT because of intestinocutaneous fistula around colostomy. These malignant mimicking FDG accumulations were disappeared after colostomy reversion. PMID:19066925

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

Science.gov (United States)

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. PMID:21293072

Imaging cervical cancer  

International Nuclear Information System (INIS)

Full text: Uterine cervical cancer is the third most common gynecological malignancy with a wide range of five year survival rate according to the tumor stage. Officially the treatment policy is chosen based on the clinical staging irrespective the substantial body of evidence that MRI is useful in evaluating malignant conditions of the female pelvis. The goal of the presentation is to highlight: 1) The results from screening tests; 2) The role of Imaging staging of cervical cancer; 3) The standard MRI protocol, recommended by the European Society of Uroradiology; 4) The new role of Imaging in guiding an individualized therapy and 5) The assessment of therapy effect. MRI, although not officially incorporated in the FIGO staging system, is already widely accepted as the most reliable imaging technique for the diagnosis, staging, treatment planning, and follow-up of cervical cancer. In summary, MRI plays a key role in staging, patient selection for treatment, and detection of disease recurrence.

Adenocarcinoma of the uterine cervix.  

Science.gov (United States)

In Finland, the incidence of cervical cancer has shown a decreasing tendency since the 1960s. The same trend, however, has not been noticed in the incidence of cervical adenocarcinoma. The reason for this is not known, although many studies have shown differences in the cause, epidemiology, and biology of the epidermoid and adenocarcinoma of the uterine cervix. A total of 106 new patients with cervical adenocarcinoma were treated at our institution from 1976 to 1980, which represents 20.4% of all cervical carcinomas treated. The mean age of the patients was 58.1 years (range, 29 to 82 years) and the peak incidence was in the group 60 to 69 years of age. Most of the patients were postmenopausal (71.7%) and the main symptom was abnormal vaginal bleeding (78.3%). The proportion of Stage I was 61.3%. Combined operative and radiation therapy was used in 74.5% of the patients. The overall 5-year survival rate was 65.1% (corrected 74.5%), which did not differ from that of patients with squamous cell carcinoma. The most significant prognostic factors were the size of the tumor, presence of pelvic lymph node metastases, and the stage of the disease. PMID:2293870

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

Blood flow MR imaging of the uterine arteries and of normal and malignant cervical tissue. Initial experiences with a 2D-STAR technique; Darstellung des Blutflusses in den Gebaermutterarterien und im normalen sowie malignen Gebaermuttergewebe mittels einer 2D-Multiphasen-Tagging-Technik  

Energy Technology Data Exchange (ETDEWEB)

Purpose. The aim of this pilot study was to evaluate a 2D-STAR technique as a non contrast-enhanced approach to demonstrate the uterine artery and its branches and to assess the cervical uterine blood flow in healthy volunteers and in patients with advanced uterine cervical carcinoma. Materials and methods. Seven healthy volunteers (mean age, 29 years) and twentytwo patients (mean age, 52 years) with advanced cancer of the uterine cervix (FIGO IIB-IVA) were prospectively examined by 2D-STAR imaging at different inversion delay times (300 ms-1900 ms) which showed the passage of a blood bolus through normal and malignant tissue of the uterine cervix. Results. The uterine artery was well visualized with short inversion delay times of 300 ms to 500 ms. It was characterized as single or multiple helical loops before dividing into its intracervical branches. The intracervical branching was observed at inversion delay times of 500 ms-700 ms. With longer inversion delay times arterial signal enhancement disappeared and cervical tissue enhancement was noted. Enhancement of benign tissue was observed at inversion delay times of 1100 ms-1700 ms, and in malignant tissue at shorter inversion delay times of 900 ms-1300 ms. The maximum of this diffuse signal enhancement of benign tissue was seen at inversion dealy times of 1500 ms (1100 ms-1700 ms), in malignant tissue at significantly (P<0.05) shorter inversion delay times of 1100 ms (900 ms to 1300). (orig.) [Deutsch] Ziel. In dieser Studie wurde untersucht, ob mittels einer 2D-Multiphasen-Tagging (2D-MPT)-Technik dynamische Informationen ueber den Blutfluss in den Gebaermutterarterien und normalem sowie malignem Gebaermuttergewebe gewonnen werden koennen. Material und Methoden. Sieben gesunde Probanden (Durchschnittsalter, 29 Jahre) und 22 Patienten (Durchschnittsalter, 52 Jahre) mit fortgeschrittenem Zervixkarzinom (FIGO IIB-IVA) wurden prospektiv mittels einer 2D-MPT-Sequenz untersucht. In einem Intervall von 300-1900 ms nach der Markierung eines arteriellen Bolus wurden neun 2D-MPT-Bilder akquiriert, die die Passage des Bolus durch die Gebaermutterarterien und normalem und malignem Gebaermuttergewebe zeigen. Ergebnisse. Die Gebaermutterarterien fuellten sich 300-500 ms nach der Blut-Bolusmarkierung und waren durch einen korkenzieherartigen Verlauf vor ihrem Eintritt in das Gebaermuttergewebe gekennzeichnet. Die intrauterinen Gefaessaufzweigungen stellten sich nach 500-700 ms dar. Nach 900-1300 ms bzw. 1100-1700 ms war die Perfusion von malignem und normalem Gewebe sichtbar, die grossen Gebaermutterarterien waren kaum bzw. nicht mehr zu sehen. Die maximale Signalintensitaet in malignem Gewebe war signifikant (p<0,05) hoeher und wurde signifikant (p<0,05) frueher erreicht als in benignem Gewebe. Schlussfolgerung. Mit Hilfe einer 2D-MPT-Sequenz gelingt ohne Verwendung von Kontrastmitteln eine komplette dynamische Darstellung der Gebaermutterarterien und der fruehen Gewebeperfusion von normalen und malignem Gebaermuttergewebe. Darueber hinaus wird malignes Gewebe frueher und staerker perfundiert als normales Gebaermuttergewebe. (orig.)

Uterine metastasis of invasive ductal breast carcinoma diagnosed by cytological examination in an asymptomatic patient: an unusual case report  

Directory of Open Access Journals (Sweden)

Full Text Available Uterine metastasis of malignant tumors occurs very rarely. Despite abnormal uterine bleeding is the most common symptom of metastatic uterine disease, less than 5% of patients may have not any gynecologic symptoms and diagnosis is made usually following abnormal cervical cytology. Here we present a case of uterine metastasis of invasive ductal breast carcinoma that was diagnosed by cervical cytological examination during breast cancer follow up. Even if there are not any gynecologic symptoms and findings in a patient who has breast cancer history, a detail systematic pelvic examination of these patients must be done yearly.

Translational augmentation of pro-matrix metalloproteinase 3 (prostromelysin 1) and a tissue inhibitor of metalloproteinases (TIMP)-1 mRNAs by epidermal growth factor and transforming growth factor alpha, but not by interleukin 1 alpha or 12-O-tetradecanoylphorbol 13-acetate in human uterine cervical fibroblasts: the possible involvement of an atypical protein kinase C.  

Science.gov (United States)

We have previously reported that epidermal growth factor (EGF) augments the translation of pro-matrix metalloproteinase 3 (proMMP-3/prostromelysin 1) and tissue inhibitor of metalloproteinases (TIMP)-1 mRNAs during the first 1-h treatment of human uterine cervical fibroblasts (Hosono, T. et al., FEBS Lett., 381, 115-118, (1996)). In this report, we have investigated the effect of interleukin 1 alpha (IL-1 alpha) and 12-O-tetradecanoylphorbol 13-acetate (TPA), potent stimulators of proMMPs and TIMP-1 production, on the translation of proMMP-3 and TIMP-1 mRNAs. When human uterine cervical fibroblasts were treated with IL-1 alpha or TPA for 2h, their translations were not augmented, whereas the steady-state levels of proMMP-3 and TIMP-1 mRNAs in the cells treated with these stimuli for 24 h were increased 13.3- and 1.3-fold by IL-1 alpha and 52.5- and 5.7-fold by TPA, respectively. By contrast, transforming growth factor alpha(TGF alpha), which also binds to EGF-receptor, enhanced their production as early as 2 h after treatment, indicating that growth factors that bind to EGF-receptor are likely to be involved in the translational enhancement of proMMP-3 and TIMP-1 mRNAs. EGF partially translocated cytoplasmic protein kinase C (PKC) to plasma membrane, but the PKC down-regulation induced by 100nM TPA did not diminish the EGF-mediated translational augmentation of proMMP-3 and TIMP-1 mRNAs. In contrast, the PKC inhibitor of 1-(5-isoquinolinesulfonyl)-2-methylpiperazine dihydrochloride (H-7) effectively suppressed the translational regulation of proMMP-3 and TIMP-1 in a dose-dependent manner during the first 2-h treatment with EGF. These results suggest that EGF and TGF alpha, but not IL-1 alpha and TPA, specifically augment the translation of proMMP-3 and TIMP-1 mRNAs and accelerate their accumulation without modifying their transcripts during the first 1-2 h treatment of human uterine cervical fibroblasts. This translational augmentation is suggested to be mediated by a TPA-insensitive atypical PKC subclass in the PKC family. PMID:8913498

Uterine torsion in term pregnancy  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction Uterine torsion has been defined as a rotation of more than 45 degrees of the uterus around its long axis that occurs at the junction between the cervix and the corpus. The extent of the rotation is usually 180 degrees, although cases with torsion from 60 to 720 degrees have been reported. Aetiopathogenesis of this condition is still unclear. Establishing clinical diagnosis of this condition is difficult, but very important for reducing maternal and fetal morbidity and mortality. Clinical symptoms are either absent or nonspecific, and the diagnosis is usually made at laparotomy. Case outlineA 31-year old patient was admitted to the Institute of Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade, as an emergency, seven days upon the established intrauterine fetal demise in the 40th gestation week. On uterine examination, the cervical length of 1.5 cm and dilatation of 3 cm were determined, as well as a palpable soft tissue formation, not resembling placenta praevia. Ultrasound examination confirmed fetal demise and exclusion of the presence of placenta praevia. The labor was completed by caesarean section. During surgery, uterine torsion of 180 degrees to the right was diagnosed. There was a stillborn male baby, and the cause of death was intrauterine asphyxia. A fibrosing and calcified accessory lobe 9x6x2.5 cm in size was observed on placental examination, which is a possible sign of initial gemellary pregnancy. Conclusion The clinical presentation of uterine torsion is variable and clinical examination and ultrasonographic scanning may be insufficient for diagnosis. The method of choice for establishing the diagnosis is magnetic resonance imaging. Once the diagnosis of uterine torsion in pregnancy is established, emergency laparotomy is indicated. Following caesarean delivery, it is necessary to surgically remove all the anatomical causes of torsion, and rotate the uterus back to its normal position. There are some authors who suggest bilateral plication of the round ligaments as a preventive procedure for repeated torsion in puerperium and following pregnancies. The effectiveness of this method requires further investigation. It is necessary to have in mind the possibility of uterine torsion in all cases of abdominal pain during pregnancy and dystocia.

Erosion and erosion-corrosion  

International Nuclear Information System (INIS)

It is very difficult to interpret the technical term of erosion-corrosion' which is sometimes encountered in piping systems of power plants, because of complicated mechanisms and several confusing definitions of erosion-corrosion phenomena. 'FAC (flow accelerated corrosion)' is recently introduced as wall thinning of materials in power plant systems, as a representative of 'erosion-corrosion'. FAC is, however, not necessarily well understood and compared with erosion-corrosion. This paper describes firstly the origin, definition and fundamental understandings of erosion and erosion-corrosion, in order to reconsider and reconfirm the phenomena of erosion, erosion-corrosion and FAC. Next, typical mapping of erosion, corrosion, erosion-corrosion and FAC are introduced in flow velocity and environmental corrosiveness axes. The concept of damage rate in erosion-corrosion is finally discussed, connecting dissolution rate, mass transfer of metal ions in a metal oxide film and film growth. (author)

Uterine leiomyoma  

International Nuclear Information System (INIS)

To correlate the signal intensity of uterine leiomyoma with its pathologic characteristics, with particular emphasis on the fibrous component, 33 magnetic resonance (MR) examinations that revealed 93 leiomyomas were prospectively studied. All patients were imaged in axial and sagittal planes with different spin-echo pulse sequences to obtain T1-, T2-weighted, and proton density images. Nondegenerative leiomyomas (N-62) showing a homogeneous signal of low intensity, and degenerative leiomyomas (N-31) with a heterogeneous signal of variable intensity on T2-weighted images could be correlated. Histopathological assessment of fiber constitution and degeneration, and MR intensity were interpreted by independent observers. There was excellent accord between the averages for MR intensity, T2 relaxation time and fiber content, although the intensity values in each fiber grade showed a wide range. The greater the fiber content the lower the MR intensity on T2-weighted images, and the shorter the T2 relaxation time (p<0.0001). In addition, the manner in which fiber distribution affected MR appearance was also elucidated. These data contribute to guidelines for precise tissue differentiation of myogenic tumors on MR images, and for MR imaging tissue diagnosis of any lesion with a considerable fibrous element.

Postpartum suppression of ovarian activity with a Deslorelin implant enhanced uterine involution in lactating dairy cows.  

Science.gov (United States)

Holstein cows received, subcutaneously a non-degradable implant containing 5mg of the GnRH agonist Deslorelin (DESL) or no implant (CON) at 2+/-1 days postpartum (dpp). All cows were injected with PGF(2alpha) at 9 dpp. Previous pregnant (PPH) and non-pregnant uterine horns (PNPH) were determined by palpation per rectum. In Experiment 1, cows [DESL implant (n=10) and CON (n=9)] were examined by ultrasonography to record ovarian structures (23, 30 and 37 dpp) and uterine horn and cervical diameters (16, 23, 30 and 37 dpp). Uterine tone was scored before ultrasonography. Vaginoscopy was conducted just after ultrasonography examination to assess cervical discharge and color of the external cervical os. Blood samples were collected on a weekly basis for hormonal analyses. In Experiment 2, cows [DESL implant (n=77) and CON (n=70)] were palpated per rectum and vaginoscopy at 30 dpp for scoring of uterine tone, uterine horns, cervical diameter, and discharge. Blood samples were collected only at 9 dpp. In Experiment 1, DESL-implant-treated cows had more Class 1 follicles (Pinvolution of the uterus and cervix, (3) increased tone of the uterine wall, (4) decreased frequency of purulent cervical discharges, and (5) reduced inflammatory processes of the reproductive tract.

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.)

Cyto-histopathological correlations in uterine cervix pathology  

Directory of Open Access Journals (Sweden)

Full Text Available linical significant cervical lesions are often correlated with epithelial cell abnormalities on cervical smears. The histologic lesions which are found in uterine cervix can not be always established only with conventional cytology. Thus, it is very important that any cytologic abnormality be subsequently correlated with biopsy for certification of a cervical lesion. The results of cervical smears and tissue diagnoses over a five year period were reviewed, being examined the correlations between the cervico-vaginal smears and the surgical specimens. All cervical smears with their subsequent biopsies and histerectomies, between 2003-2008 were retrospectively evaluated. The patients ages were between 18 and 70 years old. The cervical cytology records were verifyied and the cytodiagnosis were compared with the correspondent histopathological diagnosis. From the 5700 cervico-vaginal smears, diagnosticated in the mentioned period of time, 3835 were negative for intraepithelial lesion or malignancy. The others of 1865 presented squamous and glandular lesions, and cervical carcinoma. One case, of a 20 years old girl, had a cytodiagnostic with suspicion of sarcoma, which was confirmed on biopsy and subsequent histerectomy as a cervical embrional rhabdomyosarcoma. The exfoliative cytologic cervico-vaginal test is very important in precocious diagnosis of intraepithelial cervical lesions, especially when it its correlated with histopathologic examination. The immunohistochemical and molecular testing of high-risk HPV will contribute to a better management of cervical precancerous lesions.

Decreased type III collagen expression in human uterine cervix of prolapse uteri.  

Science.gov (United States)

The precise mechanism of prolapse uteri is not fully understood. There is evidence to suggest that abnormalities of collagen, the main component of extracellular matrix, or its repair mechanism, may predispose women to prolapse. To investigate the characteristic structure of human uterine cervix of patients with prolapse uteri, various types of collagen expression in the uterine cervix tissues of the prolapse uteri were compared to those of normal uterine cervix. After informed consent, 36 specimens of uterine cervical tissues were obtained at the time of surgery from 16 postmenopausal women with prolapse uteri (stage III-IV by the Pelvic Organ Prolapse Quantification examination) and 20 postmenopausal women without prolapse uteri (control group). Collagens were extracted from the uterine cervix tissues by salt precipitation methods. The relative levels of various collagens were evaluated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The uterine cervix was longer in the patients with prolapse uteri than those of postmenopausal controls without prolapse uteri. The ratios of type III to type I collagen in the uterine cervical tissues were significantly decreased in the prolapse uteri, as compared to those of the postmenopausal uterine cervix without prolapse. These results suggest that decreased type III collagen expression may play an important role in determing the physiology and structure of the uterine cervix tissues of prolapse uteri. PMID:22977496

Malignant mixed mullerian tumor arising from the uterine cervix: A case report  

Energy Technology Data Exchange (ETDEWEB)

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.

Progressive loss of E-cadherin immunoexpression during cervical carcinogenesis  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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.

Expression of the complement regulatory proteins decay accelerating factor (DAF, CD55), membrane cofactor protein (MCP, CD46) and CD59 in the normal human uterine cervix and in premalignant and malignant cervical disease.  

OpenAIRE

The membrane-bound complement regulators decay-accelerating factor (DAF, CD55), membrane cofactor protein (MCP, CD46), and CD59 are broadly expressed proteins that act together to protect host tissues from autologous complement. Comparison of expression profiles of these proteins between normal and pathological tissues could reveal a mechanism by which tumor cells evade complement-mediated killing. Expression of the regulators was therefore examined in the normal human uterine cervix, in cerv...

Uterine cervical carcinoma: a comparison of two- and three-dimensional T2-weighted turbo spin-echo MR imaging at 3.0 T for image quality and local-regional staging  

Energy Technology Data Exchange (ETDEWEB)

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

Normal uterine activity on a sup(99m)Tc-glucoheptonate renal scan  

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.)

Casein hydrolysate for uterine infection treatment: a patent evaluation (WO2011132191).  

Science.gov (United States)

Metritis, endometritis and pyometra are common uterus inflammatory diseases, occurring mainly in the early postpartum period of livestock and farm animals. These infections are primarily associated with contamination of the reproductive tract, in particular uterine. Uterine infections bring to uterine and cervical involution as well as sub-fertility; the high economic loss, due to costs for treatment, milk withdrawal, reduced reproductive performance and premature culling, clearly demonstrate that uterine health in the postpartum period requires substantial medical veterinary attention. A wide variety of therapies for endometritis have been reported, including mainly antibiotics administered either by systemic or local somministration. Here, the patent application WO/2011/132191, which describes an alternative treatment for uterine infection, using casein peptides, is evaluated and discussed. PMID:22458646

Long-term follow-up of neoadjuvant intraarterial chemotherapy using an original four-lumen double-balloon (4L-DB) catheter for locally advanced uterine cervical cancer  

International Nuclear Information System (INIS)

We report the therapeutic potential, long-term survival, and toxicity of neoadjuvant intraarterial chemotherapy (NAIC) using an original four-lumen double-balloon (4L-DB) catheter followed by radical hysterectomy and/or radiotherapy in patients with locally advanced cervical cancer. Sixty patients with stage IIB-IVA cervical squamous cell cancer were treated with NAIC which included cisplatin (60-70 mg/m2, day 1), mitomycin-C (10-20 mg/m2, day 1), and pirarubicin hydrochloride (THP; 10-20 mg/m2, day 1) for two courses every 21 days. The median follow up among surviving patients was 93.7 months. Among 60 eligible patients, 22 had a complete response (CR; 36.7%) including 12 with a pathologic CR (20.0%). Thirty-six patients had a partial response (60.0%), and stable disease was observed in only 2 patients (3.3%). Moreover, we found that the platinum concentration in the cervix was correlated with the clinical response (P<0.001). The 10-year progression-free survival (PFS) and 10-year survival were 90.9% and 90.9%, respectively, in patients with stage IIB disease and 66.0% and 70.7%, respectively, in patients with stage III disease. Leukopenia occurred in 86.7% of patients, but it was not very severe (grade 3, 4 in 13.3% of patients). Our results with NAIC using the 4L-DB catheter in locally advanced cervical cancer demonstrate that a high platinum concentration has beneficial effects on primary lesions and improves long-term progression-esions and improves long-term progression-free and overall survival.

Factors affecting uterine electrical activity during the active phase of labor prior to rupture of membranes.  

Science.gov (United States)

Abstract Objective: Limited data exist regarding uterine contraction intensity prior to membrane rupture. Using a novel technique of electrical uterine myography (EUM) we aimed to determine which factors affect myometrial activity during active phase of labor. Methods: EUM was prospectively measured in 37 women with singleton pregnancy at term during the active phase of labor until membranes' rupture. EUM was measured using non-invasive nine channels recorder with an EMG amplifier and three-dimensional position sensor. Uterine electrical activity was quantified with the EUM-index, defined as the mean electrical activity of the uterine muscle over a period of 10?min and measured in units of micro-Joule (microwatt per second [mW/s]). Results: The mean EUM-index at the first 10?min of the measurement was 3.3?±?0.6?mW/s. In a stepwise linear regression model accounting potential confounders EUM was significantly affected by cervical dilatation (p?=?0.005), maternal age (p?=?0.04) and previous cesarean delivery status (p?=?0.02). In a repeated measurement assessment of non-parametric Fridman's test for all subjects who had at least 10 continuouss EUM measurements, there was a significant increase in electrical uterine activity as labor progressed (p?=?0.01). Conclusion: Electrical uterine activity during the active phase of labor prior to rupture of membranes is affected by maternal age, previous cesarean delivery status and cervical dilatation. Moreover, electrical uterine activity is enhanced throughout labor. PMID:25212973

Uterine leiomyoma with tubules  

OpenAIRE

We report two cases of "uterine leiomyoma with tubules" as a new pathological entity. Since these are biphasic neoplasms (composed by epithelial and mesenchimal elements), the differential diagnosis is between mixed mullerian tumors and uterine tumors resembling ovarian sex cord tumors (UTROSCTs). In the differential diagnosis, the mixed mullerian tumors are easily excluded because of histological and immunohistochemical features. UTROSCTs are similar to the lesions we reported, and the diffe...

CRYOTHERAPY IN CERVICAL INTRAEPITHELIAL NEOPLASIA  

Directory of Open Access Journals (Sweden)

Full Text Available Cryotherapy is a time proven ablative method of treating lower grades of cervical dysplasia. It  is done using compressed CO2 or N2O refrigerant with the aim of creating an ice ball with a depth of freeze denoted by a peripheral margin of 4-5 mm of frost. It is performed using a double freeze or single freeze technique. Currently the double freeze technique of cryotherapy is an accepted treatment for mild and focal moderate dysplasia of the uterine cervix. The success of cryotherapy is determined by five factors : patient anatomy, pathology, equipment, technique and physician skill. Here we have a brief review of cryotherapy as an effective modality in treatment of lower grades of cervical intraepithelial neoplasias.

Prediction of lymph node status in uterine cervical cancer with {sup 18}FDG-PET/CT-value of primary tumor uptake; Determination par TEP-TDM au {sup 18}FDG du statut ganglionnaire dans les cancers du col uterin - interet de la mesure du SUV de la tumeur primitive  

Energy Technology Data Exchange (ETDEWEB)

Purpose. To evaluate the value of {sup 18}F-fluoro-2-deoxyglucose (F.D.G.) PET-CT and maximal standardized uptake value (SUV{sub max}) of the primary tumor for lymph node staging in cervical cancer. Materials and methods. This retrospective study involved a series of 18 consecutive patients who had benefited from PET-CT and MRI at initial staging for a stage IB or higher cervical carcinoma. The SUV{sub max} of each primary tumor was measured retrospectively. All patients had been previously treated by radio chemotherapy. Lymph node status was obtained in 12 of 18 cases. Results. The sensitivity and specificity for determining lymph node status was 80 and 86%, respectively, for PET-CT, and 80 and 71% for MRI. In 16.6% of cases, PET-CT revealed unknown sus-diaphragmatic lesions. SUV{sub max} of the primary tumor was significantly higher in the N+ than in the N- group (15.6 {+-}1.6 vs 8.5{+-}3.9, p < 0.01). The optimal threshold was determined to be 10.8 from ROC analysis. Conclusion. When staging with F.D.G. PET-CT, SUV{sub max} of a primary cervical cancer seems to be a good predictor of lymph node status. This could lead to an intensification of treatment for patients whose SUV{sub max} is higher than 10.8. A prospective study would allow to assess a potential benefit of treatment intensification for patients with SUV{sub max} higher than 10.8. (authors)

RAPIDARC (RA) in the uterine cervical cancer; dosimetric gain vs 3D-Crt; RAPIDARC (RA) en el cancer de cervix uterino; ganancia dosimetrica vs 3D-CRT  

Energy Technology Data Exchange (ETDEWEB)

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.

The assessment of the angiogenesis in the uterine cervix carcinogenesis  

Directory of Open Access Journals (Sweden)

Full Text Available The uterine carcinoma represents one of the most frequent malignant tumors in female. Great progresses were made in the understanding of the mechanisms of the appearance and evolution of the tumors, and also in the early diagnosis of them. In the present time, the discussions are centered on the angiogenesis and the neovascularisation. During the researches regarding the new factors of prognosis in cervical carcinomas, we are interesting firstly in the study of neoangiogenesis and its predictive role. The microanatomic quantitative study was made on fragments which were processed from uterine cervix dysplasias, preinvasive and invasive tumors. The sections were stained specific immunohistochemically (CD34 and examined with an interactive digital program. We have quantified the density of the microvessels/mm2 tumor stroma and the density of the microvessels/mm2 tumor. The preliminary results regarding the study of the microvessels in uterine cervix carcinomas show a positive correlation between the density and the evolution of the tumor, the angiogenetic process rises simultaneously with the risk of metastasis. This study shows a significant correlation between the density of vessels and the evolution of the uterine cervix carcinomas, the appearance of recurrences and metastasis. The quantification of the angiogenesis is an indicator with an high degree of precision, with is used for the detection of the aggressiveness and malignancy of the uterine cervix tumors.

Studies on the diagnosis of uterine tumor by 201-thallium-chloride  

International Nuclear Information System (INIS)

Cases of gynecological tumor mainly uterine benign and malignant tumors were evaluated using 201Thallium-Chloride (201Tl-Cl) after intravenous injection. The positive scans of 100% in 42 cases of uterine myoma including 29 cases of leiomyoma, 8 cases of adenomyosis and 5 cases of combined type myoma, also 100% in 8 cases of body cancer indicating adenocarcinoma and 25% in 12 cases of cervical cancer indicating squamous cell carcinoma were observed. The smallest focal lesion for the positive scans was needed approximately more 5 cm in diameter in the cases of leimyoma. The most accumulation of activities was showed in adenomyosis or adenocarcinoma with much adenoid structure in the pathological study. Accumulation of 201Tl in uterine benign and malignant tumors was suggested the analog of potassium. The mechanism of tumor affinity was correlated to perfusion volume and the acceleration of the potassium metabolism in a tumor. On the other hand, we suggested the diagnosis of the malignant uterine tumor should be attended due to 201Tl was accumulation also in the benign uterine tumor. The uterine scanning using 201Tl-Cl was acknowledged to be very useful and safe indicating early detection at 20 minutes after the injection, (non-traumatic procedure and non-visualized bone tissues). In conclusion, this radioisotopical procedure was indicated high value of screening examination in the diagnosis of uterine tumor. (authorin the diagnosis of uterine tumor. (author)

Em relação à importância do exame, a maioria relatou ser a prevenção e a descoberta precoce da doença o fator mais importante. Sobre o conhecimento da doença, relataram ter ouvido falar, visto na TV, mas o medo da doença e até do nome câncer é maior que a necessidade de realizar o exame.O que impede a realização do exame é o medo do resultado e a falta de tempo. Os dados permitiram concluir que é necessário aumentar a cobertura dos exames; orientar as mulheres através de campanhas e, ainda, desmistificar a técnica e os resultados dos mesmos.The aim of this work was to verify women’s knowledge of cervical uterine cancer prevention exam, its importance and women’s feelings towards it. This was done in order to better understand the prevention practice. This is an exploratory descriptive study. The women’s major feelings towards this exam are fear and shame. Regarding this exam importance, most of them said that the prevention and the precocious discovery of the illness are the most important factors. Knowledge of the disease was acquired through conversations and TV programs, even though fear of the disease is greater than the need to undertake the exams. The latter is impaired by fear regarding their result and by lack of time to undertake them. Data show that exam coverage should be broadened; more orientation should be given through campaigns; technique and exam results should be demystified.

Relationships between uterine and fetal traits in rabbits selected on uterine capacity.  

Science.gov (United States)

The aim of this study was to investigate whether uterine capacity (UC) in rabbits was related to uterine horn length and weight and whether these uterine traits and vascular supply were related to fetal development and survival. Data from 48 unilaterally ovariectomized (ULO) does of the High and 52 ULO does of the Low UC lines of a divergent selection experiment on UC were used. Does were slaughtered on d 25 of fifth gestation. The High line showed higher ovarian weight (0.08 g, P < 0.05) linked to a higher ovulation rate (1 ovum, P < 0.05) and greater length of the empty uterine horn. There were no differences between lines in the remaining doe traits. The number of implanted embryos and live fetuses, fetal survival, and uterine weight and length were positively associated and explained most of the observed variation. Average weights of the live fetuses and their fetal and maternal placentae were not related to uterine weight and length. The linear regression coefficient of full uterine horn length on the number of live fetuses was 2.43 +/- 0.21. The weight of the full uterine horn showed a small quadratic relationship (P < 0.05) with the number of live fetuses. Full uterine horn length, after adjusting for the number of embryos, was negatively associated (P < 0.001) with the number of dead fetuses. The linear regression coefficient of average fetal placental weight of the live fetuses on number of implanted embryos was higher (P < 0.10) in the Low line (-0.23 +/- 0.04 vs. -0.12 +/- 0.04). The linear regression coefficient of average weight of the live fetuses on the average weight of their fetal placentae was higher (P < 0.10) in the High line (2.56 +/- 0.47 vs. 1.27 +/- 0.57). The High line was more efficient, most likely because an increase in intrauterine crowding has a lesser effect on the development of fetal placentae and fetuses. The fetal position within the uterus did not affect the proportion of dead embryos. Fetuses with placentae receiving a single blood vessel had a higher probability of death (P < 0.001) and the lowest weight. There was no difference between lines for individual weight of the live fetuses, but the High line showed higher individual weights of fetal (P < 0.01) and maternal placentae (P < 0.10). Live fetuses in the midportion of the uterus were lighter in weight (P < 0.05) than in the oviductal and cervical regions (20.3 vs. 21.6 and 21.7g). Increasing uterine capacity increases uterine length and decreases weights of fetus and fetal placenta in rabbits. PMID:12772854

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.

Smad4 deficiency in cervical carcinoma cells.  

Science.gov (United States)

Squamous cell carcinoma of the uterine cervix is one of the most frequent cancers affecting women worldwide. Carcinomas arise from cervical intraepithelial lesions, in which infection with high-risk human papillomavirus types has led to deregulated growth control through the actions of the viral E6 and E7 oncoproteins. The molecular mechanisms underlying progression to invasive tumor growth are poorly understood. One important feature, however, is the escape from growth inhibition by transforming growth factor beta (TGF-beta). Loss of chromosomal arm 18q is among the most frequent cytogenetic alterations in cervical cancers and has been associated with poor prognosis. Since the TGF-beta response is mediated by Smad proteins and the tumor suppressor gene Smad4 resides at 18q21, we have analysed the Smad4 gene for cervical cancer-associated alterations in cell lines and primary carcinomas. Here, we report Smad4 deficiency in four out of 13 cervical cancer cell lines which is due to an intronic rearrangement or deletions of 3' exons. All cell lines, however, showed either absent or moderate responsiveness to TGF-beta irrespective of their Smad4 status. In 41 primary squamous cervical carcinomas analysed, 10 samples showed loss of Smad4 protein expression and 26 samples a reduced expression. Altogether, our results strongly suggest that Smad4 gene alterations are involved in cervical carcinogenesis. PMID:15531914

Detection of human papillomavirus in urine and cervical swabs from patients with invasive cervical cancer.  

Science.gov (United States)

Despite the high prevalence of both human papillomavirus (HPV) infections and cervical cancer among Zimbabwean women, the ability to test for HPV infection of the uterine cervix is limited by a lack of an easy sample collection method that does not require gynecological examination. The presence of HPVs in urine and cervical swab samples collected from 43 women who presented with invasive cervical cancer was investigated. HPV detection was done by means of degenerate primers in a nested polymerase chain reaction (PCR). Typing of HPVs was done using restriction fragment length polymorphism (RFLP) analysis. HPV was identified and typed in 98% (42/43) of cervical swabs and 72% (31/43) of paired urine samples. HPV type 16 was the most common (25/42, 59%), followed by types: 33 (13/42, 31%), 18 (6/42, 14%), and 31 (1/42, 2%). Type-specific concordance between cervical and urine samples was high (22/28, 79%). Therefore, the HPV types identified in urine samples in most cases represent the same HPV type infecting the cervical epithelium. The results suggest that urine may be a practical sample for testing of HPV urogenital infection. Further research is required before the detection of HPV in urine can be applied in the routine cervical screening programs. PMID:12858416

Complete tamponade system for management of severe postpartum vaginal haemorrhage due to uterine atony.  

Science.gov (United States)

A 30-year-old, 39?weeks pregnant, multiparous woman with single fetus, attended our obstetric clinic with complete cervical dilation in intractable mentum anterior presentation. The fetus was delivered by caesarean section with vertical uterine incision under general anaesthesia and lithotomy position. After surgery, examination of the vagina revealed multiple, serious tears with severe haemorrhage. Vaginal bleeding could not be controlled by sutures and concurrently uterine atony developed, which could not be controlled with medical treatment. Owing to intractable bleeding from uterus and vagina, a complete tamponade system was used. After the instillation of the uterine balloon with 500?mL and vaginal balloon with 300?mL liquid, the bleeding was controlled. The estimated blood loss was 3200?mL. The vaginal wound healed well during the postoperative 2?weeks. A complete tamponade system may be an effective treatment method for treatment of postpartum haemorrhage owing to vaginal lacerations and uterine atony. PMID:25452297

Abnormal uterine bleeding.  

Science.gov (United States)

Abnormal uterine bleeding is a common presenting symptom in the family practice setting. In women of childbearing age, a methodical history, physical examination, and laboratory evaluation may enable the physician to rule out causes such as pregnancy and pregnancy-related disorders, medications, iatrogenic causes, systemic conditions, and obvious genital tract pathology. Dysfunctional uterine bleeding (anovulatory or ovulatory) is diagnosed by exclusion of these causes. In women of childbearing age who are at high risk for endometrial cancer, the initial evaluation includes endometrial biopsy; saline-infusion sonohysterography or diagnostic hysteroscopy is performed if initial studies are inconclusive or the bleeding continues. Women of childbearing age who are at low risk for endometrial cancer may be assessed initially by transvaginal ultrasonography. Postmenopausal women with abnormal uterine bleeding should be offered dilatation and curettage; if they are poor candidates for general anesthesia or decline dilatation and curettage, they may be offered transvaginal ultrasonography or saline-infusion sonohysterography with directed endometrial biopsy. Medical management of anovulatory dysfunctional uterine bleeding may include oral contraceptive pills or cyclic progestins. Menorrhagia is managed most effectively with nonsteroidal anti-inflammatory drugs or the levonorgestrel intrauterine contraceptive device. Surgical management may include hysterectomy or less invasive, uterus-sparing procedures. PMID:15117012

Este estudo se propõe a realizar revisão da literatura buscando evidências de benefícios conseqüentes ao tratamento da ectopi [...] a. MÉTODOS: Pesquisa nas bases Medical Literature Analysis and Retrieval Sysem Online (Medline), Excerpta Medica Database (Embase), Literatura Latino-Americane e do Caribe em Ciências da Saúde (Lilacs), Biblioteca Cochrane e seis livros especializados. 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.

Radiologic diagnosis and treatment of iatrogenic acquired uterine arteriovenous malformation  

Energy Technology Data Exchange (ETDEWEB)

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.

Studies on the diagnosis of uterine tumor by 201-thallium-chloride  

Energy Technology Data Exchange (ETDEWEB)

Cases of gynecological tumor mainly uterine benign and malignant tumors were evaluated using /sup 201/Thallium-Chloride (/sup 201/Tl-Cl) after intravenous injection. The positive scans of 100% in 42 cases of uterine myoma including 29 cases of leiomyoma, 8 cases of adenomyosis and 5 cases of combined type myoma, also 100% in 8 cases of body cancer indicating adenocarcinoma and 25% in 12 cases of cervical cancer indicating squamous cell carcinoma were observed. The smallest focal lesion for the positive scans was needed approximately more 5 cm in diameter in the cases of leiomyoma. The most accumulation of activities was shown in adenomyosis or adenocarcinoma with much adenoid structure in the pathological study. Accumulation of /sup 201/Tl in uterine benign and malignant tumors was suggested the analog of potassium. The mechanism of tumor affinity was correlated to perfusion volume and the acceleration of the potassium metabolism in a tumor. On the other hand, we suggested the diagnosis of the malignant uterine tumor should be attended due to /sup 201/Tl accumulation also in the benign uterine tumor. The uterine scanning using /sup 201/Tl-Cl was acknowledged to be very useful and safe indicating early detection at 20 minutes after the injection, (non-traumatic procedure and non-visualized bone tissues). In conclusion, this radioisotopical procedure was indicated to be a high value screening examination in the diagnosis of uterine tumor.

Staging of carcinoma of the uterine cervix and endometrium  

International Nuclear Information System (INIS)

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.)

Low-cost technology for screening uterine cervical cancer / Technique peu coûteuse de dépistage du cancer du col utérin / Tecnología de bajo costo para el cribado del cáncer cervicouterino  

Scientific Electronic Library Online (English)

Full Text Available SciELO Public Health | Language: English Abstract in spanish 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.

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%

Should helical tomotherapy replace brachytherapy for cervical cancer? Case report  

Directory of Open Access Journals (Sweden)

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.

Detection of Human Papillomavirus in Chronic Cervicitis, Cervical Adenocarcinoma, Intraepithelial Neoplasia and Squamus Cell Carcinoma  

Directory of Open Access Journals (Sweden)

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

Surgical uterine drainage and lavage via direct trans-cervical catheterisation using a 5 % povidone-iodine in saline solution was performed successfully in 8 bitc [...] hes with pyometra. All bitches conceived and whelped without complications subsequent to this treatment. It is concluded that this method offers an effective alternative treatment for canine pyometra with shorter recovery times as well as good clinical recovery and pregnancy rates in bitches destined for further breeding.

MR features of isolated uterine relapse in an adolescent with acute lymphoblastic leukaemia  

Energy Technology Data Exchange (ETDEWEB)

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.)

Postpartum uterine infection in cattle.  

Science.gov (United States)

Postpartum uterine infections results from uterine contamination with bacteria during parturition. The prevalence of uterine infections varies considerably among studies. Uterine infection implies adherence of pathogenic organisms to the mucosa, colonization or penetration of the epithelium, and/or release of bacterial toxins that lead to establishment of uterine disease. The development of uterine disease depends on the immune response of the cow, as well as the species and number (load or challenge) of bacteria. The postpartum uterus has a disrupted surface epithelium in contact with fluid and tissue debris that can support bacterial growth. A variety of species of bacteria, both Gram-positive and Gram-negative aerobes and anaerobes, can be isolated from the early postpartum uterus. Most of these are environmental contaminants that are gradually eliminated during the first 6 weeks postpartum. A normal postpartum cow resolves uterine infection by rapid involution of the uterus and cervix, discharge of uterine content, and mobilization of natural host defenses, including mucus, antibodies and phagocytic cells. Clinical signs of uterine infection vary with the virulence of the causative organisms and the presence of factors that predispose to the disease. The treatment of endometritis and metritis in bovine should be directed towards improving fertility. The antibiotic should be active against the main uterine pathogens and should maintain its activity in the environment of the uterus. Also, should not inhibit the normal defense mechanisms and should be well tolerated and not induce irritation in the endometrium. Effective use of hormones in uterine infection requires knowledge of both normal reproductive endocrinology and the therapeutic characteristics of available hormonal preparations. PMID:18280065

Routine cervical dilatation during elective caesarean section. Should we continue?  

Science.gov (United States)

The caesarean section rate is on the increase globally, with its attendant complications. One of the measures adopted by obstetricians to decrease complications, such as endometritis and blood loss is intraoperative cervical dilatation during elective caesarean section. A multicentre double blind randomised controlled trial was carried out in Enugu, Nigeria, to ascertain the usefulness of this practice. A total of 208 pregnant women were randomised: 104 had intraoperative cervical dilatation and the other 104 did not have their cervices dilated. All the patients had similar preoperative, intraoperative and postoperative care and were followed up to 6 weeks postpartum. There was no significant difference between the two groups. In conclusion, the study shows no benefit in routine intraoperative cervical dilation. Practitioners must make sure that neither the placenta nor fetal membrane is overlying the internal os before they close the uterine wound. PMID:25057991

Limitations of CT and ultrasound diagnoses in the evaluation of uterine cancer involvement  

Energy Technology Data Exchange (ETDEWEB)

The concordance rates between preoperative diagnostic imagings and postoperative pathologic findings were examined in a total of 36 patients with resectable uterine cancer (19 with cervical cancer and 27 with endometrial cancer). The accuracy of CT was 47 % in the evaluation of cervical cancer involvement to the parametrium; and was 83 % in the evaluation of wall involvement of endometrial cancer. The concordance rate was 74 % in the evaluation of stage-grouping in endometrial cancer. Out of 8 patients with resectable stage II cervical cancer, four (50 %) were found to have had involvement to the parametrium by transrectal echography. The results indicate that CT scanning and transrectal echography have limitations in the diagnosis of cervical cancer involvement to the parametrium. (Namekawa, K.).

Detection of congenital uterine malformation by using transvaginal three-dimensional ultrasound.  

Science.gov (United States)

This study assessed the clinical application of transvaginal three-dimensional ultrasound (3D TVUS) in the diagnosis of congenital uterine malformation. A retrospective study was performed on 62 patients with congenital uterine malformation confirmed hysteroscopically and/or laparoscopically. The patients were subjected to transvaginal two-dimensional ultrasound (2D TVUS) and 3D TVUS. The accuracy rate was compared between the two methods. The accuracy rate of 3D TVUS was (98.38%, 61/62), higher than that of 2D TVUS (80.65%, 50/62). 3D TVUS coronal plane imaging could demonstrate the internal shape of the endometrial cavity and the external contour of the uterine fundus. It allowed accurate measurement on the coronary plane, and could three-dimensionally show the image of cervical tube, thereby providing information for the diagnosis of some complex uterine malformation. 3D TVUS imaging can obtain comprehensive information of the uterus malformation, and it is superior to 2D TVUS for the diagnosis of congenital uterine malformations, especially complex uterine anomaly.

Cervical laminoplasty for multilevel cervical myelopathy.  

Science.gov (United States)

Cervical spondylotic myelopathy can result from degenerative cervical spondylosis, herniated disk material, osteophytes, redundant ligamentum flavum, or ossification of the posterior longitudinal ligament. Surgical intervention for multi-level myelopathy aims to decompress the spinal cord and maintain stability of the cervical spine. Laminoplasty was major surgical advancement as laminectomy resulted in kyphosis and unsatisfactory outcomes. Hirabayashi popularised the expansive open door laminoplasty which was later modified several surgeons. Laminoplasty has changed the way surgeons approach multilevel cervical spondylotic myelopathy.

Neuroendocrine differentiation in a case of cervical cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Neuroendocrine neoplasms may occur in the uterine cervix, although rarely; it accounts for 0.5-1% of all malignant tumors of the uterine cervix. A case report of an Ethiopian female presented at the Gynecology Out-Patient Clinic at Jimma University Hospital, complaining from irregular vaginal bleeding over the previous three months. Clinically there was a cauliflower cervical mass; histopathologically it was formed of sheets of small cell tumor; that further showed neuroendocrine differentiation, as demonstrated by chromogranin-A positivity. It is important to differentiate small cell carcinoma from other malignant tumors of the uterine cervix. Morphological features play an important role in making a diagnosis and the immunohistochemistry study can offer an additional useful assistance

Continuous cervical dilatation monitoring by ultrasonic methods during labor.  

Science.gov (United States)

Continuous recording of cervical dilatation during labor has been investigated in 13 pregnancies. The recordings were obtained with an ultrasonic cervimeter that continuously monitors cervical dilatation from the transit time of ultrasound signals between two piezoelectric crystals attached on the uterine cervix. A small spring-loaded clip allowed each crystal to be fixed on the rim of the cervical os. Clinical accuracy was +/- 0.6 cm. When the ultrasound recording of cervical dilatation is compared to the intrauterine pressure curve, it is characterized by a baseline and wave-shape curve of dilatation (DWP). The maximal amplitude component is called cervical maximal plasticity. The onset of the DWP is related to cervical resistivity, and the end of DWP reflects the relaxation time of cervical dilatation. The data show that as dilatation enters the active phase of labor, the plasticity, the resistivity, and the duration of relaxation of the cervix increase. These observations are discussed and related to the structural changes of the cervix during labor. PMID:696778

The aim of our study was to determine the pattern of female reproductive organ growth in Indian girls from birth to 18 years of age and to correlate the uterine length, mean ovarian volume (MOV) and Fundo Cervical Ratio (FCR) with chronological age, bone age and pubertal breast staging. A cross sectional study was performed on 218 girls from birth to 18 years of age. Height, weight, stage of puberty, X-ray for bone age and transabdominal ultrasounds were performed on all girls. Higher chronological age, bone age and increase in breast stage significantly predicted higher MOV (P uterine length (P uterine length and FCR are positively correlated with chronological age, bone age, height, weight and breast staging. Data from present study may be useful in screening cases of precocious puberty and other disorders that may need further evaluation. PMID:16891683

Normal uterine activity on a sup(99m)Tc-glucoheptonate renal scan  

Energy Technology Data Exchange (ETDEWEB)

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.).

Biomarkers in Cervical Cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Cervical cancer, a potentially preventable disease, remains the second most common malignancy in women worldwide. Human papillomavirus (HPV is the single most important etiological agent in cervical cancer, contributing to neoplastic progression through the action of viral oncoproteins, mainly E6 and E7. Cervical screening programs using Pap smear testing have dramatically improved cervical cancer incidence and reduced deaths, but cervical cancer still remains a global health burden. The biomarker discovery for accurate detection and diagnosis of cervical carcinoma and its malignant precursors (collectively referred to as high-grade cervical disease represents one of the current challenges in clinical medicine and cytopathology.

[Congenital cervical agenesis: pregnancy after transmyometrial embryo transfer].  

Science.gov (United States)

Cervical agenesis is a rare congenital pathology linked to an anomaly of development of the Mullerian system. We described a case report about a 22-year old woman, consulting for infertility, who had a complete cervical agenesis. The first evaluation suggested a 46 XX karyotype and a normal ovarian reserve. The surgical examination confirmed the absence of cervix with impossibility of catheterization. She became pregnant thanks to an in vitro fertilization (IVF) with transmyometrial embryo transfer. Caesarean was decided at 36 weeks of gestation (WG) due to spontaneous uterine contractions. An injection of medroxyprogesterone was made after the placenta delivery in order to warning the partum hemorrhage. The ultrasound examination, realized 15 days after caesarean, underlined a good uterine involution. The surgery by cervico-vaginal anastomosis can be offered to patients because it offers chances of spontaneous pregnancies. But this surgery exposes women to a risk of failure, and of severe complications such as pain or infection, and might end in a hysterectomy. By choosing the transmyometrial transfer by vaginal way, the patient was exposed to the risk of spontaneous miscarriage. It was raising the problem of the uterine evacuation. This delivery after 34 WG is encouraging for the infertility by cervical agenesis. PMID:24842642

Uterine prolapse in pregnancy: risk factors, complications and management.  

Science.gov (United States)

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.
