Sample records for cervix uteri cancer

  1. Sexual dysfunction after radiotherapy for cancer of the cervix uteri

    International Nuclear Information System (INIS)

    Investigations of sexual consciousness and sexual dysfunction after radiotherapy for cancer of the cervix uteri were performed on patients of middle and old ages by questionnaires and questionning by doctors, and the following results were obtained. 1. Before radiotherapy, sexual activity was most prominent in their twenties and thirties. However, patients who were in fifties when this study was performed had most active sexual lives during the ages from 35 to 50 years. 2. Frequencies of sexual intercourse decreased markedly just before radiotherapy, and many patients received radiotherapy when sexual activity fell. 3. 32% of the patients have not experienced sexual intercourse after radiotherapy. 4. Decreases in the sex urge, sexuality, vaginal dicharge, and frequency of sexual intercourse after radiotherapy were recognized in 77%, 77%, 70%, and 93% respectively. 5. Patients who became unwilling to maintain sexual lives after radiotherapy because of fear about recurrence or aggravation of cancer were 38% by questionnaires and 49% by questionning by doctors. 6. Pains on sexual intercourse were found in 69% by questionnaires and 49% by questionning by doctors. Most pains occurred at pennis insertion and was thought to be due to atrophy and inflammation of vagina and external genitalia in most cases. 7. Both vaginal damages and sexual dysfunction in patients with radiotherapy following surgery for cancer of the cervix uteri, in patients with radiotherapy alone for cancer of the cervix uteri, and in patients with radiotherapy following surgery for cancer of the ovary and corpus uteri were marked, modest and mild, respectively. 8. Vaginal damage score was higher in patients treated more than 5 years before than those less than 2 years ago, but there were no differences in sexual dysfunction score between both groups.

    Full Text Available Objective: to define a role of magnetic resonance imaging (MRI in the follow-up of patients with cancer of the cervix uteri (CCU, who have undergone radiation therapy and chemoradiation therapy and to describe the types of the MRI pattern of recurrent CCU in the pelvic region.Materials and methods. The results of a follow-up of 82 patients with a 4-47- (median 12 months month history of invasive CCU were analyzed.Results. Out of the 82 patients with invasive CCU, 25 were found to have pelvic recurrences; in 23 cases MRI revealed the latter (in the cervix uteri (n = 6, corpus uteri (n = 2, vagina (n = 2, parametrium (n = 2, iliac (n = 10, paraaortic (n = 5 lymph nodes, and pelvic wall (n=5.Conclusion. The findings suggest that pelvic MRI is an effective technique to detect and estimate the extent of a pelvic recurrence and it is expedient to incorporate it into the scope of a follow-up after radiation therapy and chemoradiation therapy in patients with invasive CCU.

Three- and five-year overall and relapse-free survival rates have been obtained for stages: 82.5 and 82.5%; 78.4 and 78.4% for Stage IIb; 57 and 52.3%; 41.6 and 41.6 for IIIb; 53.3 and 47.3%; 42.4 and 37.7% for IVb, respectively.

  5. Local use of metronidazole in dimethylsulfoxide in radiotherapy of cervix uteri cancer patients

    International Nuclear Information System (INIS)

    A method of the local use of metronidazole dissolved in dimethylsulfoxide (DMSO) for cervix uteri cancer patients was worked out. Applications of 1-2 g of metronidazole were well tolerated by the patients. Metronidazole concentrations in cervical tumors were high (about 1000 μg/g), in the blood they did not exceed 16 μg/ml. Experiments showed that metronidazole in DMSO diffused in the tissue, its concentrations at a distance of 2-3 cm from the surface were 180-260 μg/g. The local use of metronidazole in DMSO caused an increase in the rate of tumor radiation regression

    Full Text Available Human papillomavirus (HPV that is a main cause of cancer of the cervix uteri (CCU has immunogenic properties, i.e. an abilityto activate antiviral immunity responses as adaptive HPV-specific and innate ones. For this reason, despite multiple mechanisms generated by HPV to avoid immunity responses, the human body can eliminate the infection in most cases. At the same time, CCU results from the combined influence of many factors of different nature, among which the factors that impair the normal course of an immune response are of vital importance.This review describes the major factors and mechanisms, which promote the establishment of persistent HPV infection and the progression of dysplasia to cancer, on the one hand, and allow the tumor cells in CCU to restrict the body’s immune reactions, on the other Immune disorders induced by the virus and/or tumor cells are considered at both local and systemic levels. Particular emphasis is placed on the molecular mechanisms that can change the population composition and functional activity of leukocytes and the cytokine profile of cells and can form the tumor suppressor microenvironment.

  7. A Systematic Overview of Radiation Therapy Effects in Cervical Cancer (Cervix Uteri)

    International Nuclear Information System (INIS)

    A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomized trials. In total, 35 scientific articles are included, involving 7,952 patients. The results were compared with those of a similar overview from 1996 including 34,024 patients. The conclusions reached can be summarized in these points: There are limited scientific data supporting that postoperative pelvic radiotherapy improves disease-free survival in early cervical cancer. No firm conclusion can be drawn. There is moderate scientific evidence that external beam radiotherapy combined with brachytherapy gives a similar disease-free and overall survival rate as radical hysterectomy in early cervical cancer. There is strong scientific evidence that concomitant radiochemotherapy improves disease-free and overall survival compared to radiotherapy alone in early cervical cancer. The NCI has recently published an announcement stating that cisplantin-based chemotherapy should be used concomitantly with radiotherapy in cervical cancer. No solid documentation for this statement can be found concerning locally advanced stages (>IIB). There is a strong scientific evidence that cisplatin-based chemotherapy given concomitantly with radiotherapy is superior to concomitant chemotherapy with hydroxyurea. There is no scientific evidence to show that neoadjuvant chemotherapy followed by radiotherapy improves disease-free or overall survival compared to radiotherapy alone in patients with localized cervical cancer. There is moderate scientific evidence that high-dose-rate brachytherapy gives the same local control rate as low-dose-rate brachytherapy but with fewer rectal complications

    Full Text Available Cervical cancer (CC morbidity is analyzed on the basis of the data of the Karelian cancer register over the period 1998-2007. During this period, 816 cases of CC were registered and 126 were found at an antenatal clinic (AC. Its early detection rate was ascertained to be 96% during screening at the AC. A comprehensive examination was made in 1742 women with various cervical diseases, of them 37.5% were infected with human papillomavirus (HPV. High-grade dysplasia and carcinoma in situ were diagnosed in 6.6% of the HPV-infected patients. Large-scale screening for HPV infection and pretumor disorders with their further treatment will aid in reduc- ing CC morbidity and mortality rates.

  10. Urothelial cells in smears from cervix uteri

    2012-01-01

    Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper.

    The cervix uteri is a rigid tube which connects the uterus with the vagina and during most of the time it is firmly closed. During oestrus, late pregnancy and parturition, the morphological appearance in the cervix changes markedly, resulting in a softer cervix, which during parturition can even be stretched open to a diameter that is more than a tenfold larger than before. During gyneacological interventions, such as artificial inseminations in several animal species, or in women it would be...

    International Nuclear Information System (INIS)

    A retrospective and descriptive study was conducted to characterize the behavior of cervix cancer in a sample of 162 patients with this diagnosis during 2003-2009 in the Isla de la Juventud municipality. From the review of case reports from the National Unit of Cancer the individual medical records of Teaching General Hospital of this municipality and from the National Institute of Oncology and Radiology, as well as the deceased persons, it was possible to note that the 63% of cases were women aged 34-57 and that the 20% was in ages outside the screening program. The NIC and/or infection by HPV and smoking were the more frequent risk factors. There was predominance of large cells epidermoid non-keratinized carcinoma and the O stage or in situ. Most of patients were operated on is initial therapy. The great mortality was between fifth and sixth decades of life with a acceptable survival at 5 years

    The report presents results of investigation of the neck of the womb (cervix) of 64 women aged from 19 to 70, that formed 4 clinical groups (1st group: 15 women without any pathology of the cervix, 2nd group: 27 women with the erosion, 3rd group: 11 women with dysplasia, 4th group: 11 women with cancer of the cervix). The aim of this research is to assess the capabilities of electrical impedance tomography in the diagnostics of the cervix diseases. The methods of the research were: visual examination with the speculum, colposcopy, and biopsy of the cervix. Also the new method of visualization of the cervix was used - electrical impedance tomography with the help of gynecological impedance tomograph (GIT). The following results were obtained. The electrical conductivity of the cervix in norm and in different pathology has different indices, which allow differential diagnostics of benign and malignant diseases. Summary: the method of electrical impedance tomography allows not only visually estimate portio vaginalis, but receive indices of electrical conductivity of the cervix on the depth up to 0.8 cm and thereby reveal pathological changes in epithelium without invasive and operative intervention.

  16. Prevention and treatment of early radiation-induced injuries of the urinary bladder in carcinoma of the cervix and corpus uteri

    International Nuclear Information System (INIS)

    The report discusses early-onset radiation injuries in the urinary bladder of more than 1000 patients with cancer of the cervix and corpus uteri. Clinical symptoms of such injuries were observed in 487 patients (44.3%). In 47 (10%), the lesions were pronounced. The degree of radiation-induced cystitis was evaluated on a 6-point scale used by WHO classification (1982). Said lesions mainly occurred at stage III of tumor and predominantly in cases of cancer of the corpus uteri. Complications development was stimulated by vascular lesions, diabetes mellitus and inflammatiry processes in pelvic organs. Radiation injuries were treated by standard procedures as well as with immobilised trypsin administered in a cellulose powder vehicle. this method proved the immobilised trypsin adminstered in a cellulose powder vehicle. This method proved the most effective. Since patients suffering early-onset radiation-induced destructive injuries are at high risk of further exacerbation at later stages, they should be followed-up closely

  17. Pain management in cancer cervix

    2005-01-01

    Full Text Available Cancer of the cervix uteri is a common cause of pain among women. On the physical realm, the cancer may cause somatic [soft tissue and bone], visceral and neuropathic pain [lumbosacral plexopathy]. Radiotherapy and chemotherapy may cause neuropathy too. Psychological, social and cultural factors modify the pain. Evaluation of the individual type of pain and a patient-centred approach are fundamental requirements for rational management. Disease modifying treatment like radiotherapy and chemotherapy must be considered when applicable. Pain control is usually achieved by the use of WHO three-step ladder, remembering that possible association of renal dysfunction would necessitate caution in the use of NSAIDs and opioids. Side effects must be anticipated, prevented when possible, and aggressively treated; nausea and vomiting may already be present, and constipation can worsen pain when there is a pelvic mass. Pain emergencies can be treated by quick titration with intravenous morphine bolus doses. Neuropathic pain may warrant the use of usual adjuvants, with particular reference to cortico-steroids and the NMDA antagonist, ketamine. In intractable pain, many neurolytic procedures are tried, but a solid evidence base to justify their use is lacking. Continuous epidural analgesia with local anaesthetic and opioid may be needed when drug therapy fails, and desperate situations may warrant interventions such as neurolysis. Such physical measures for pain relief must be combined with psychosocial support and adequate explanations to the patient and the family.

  18. Effects of radiotherapy on immunity in patients with localized carcinoma of the cervix uteri

    International Nuclear Information System (INIS)

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

    The causes of precancerous and cancerous diseases of the cervix are disputed. In women with menstrual disorders usually benign cervical disease is 5 times higher. In the 1960s the theory of hormonal genesis of cervical disease was advanced as similar pathogenetic processes in the cervix, endometrium, myometrium, and breasts resulted in hyperplastic changes in these organs. Ectopia can occur during sexual maturation under the influence of sex hormones. The maximum frequency (65.5%) of ectopia occurred up to age 20. Cervical ectopia can occur under use of oral contraceptives (OCs) for 6-12 months but it vanishes after discontinuation. In a study of 17,942 women aged 18-58 increased risk of preinvasive carcinoma of the cervix was found under longterm use of OCs. Increased frequency of cervical intraepithelial neoplasm from .9/10,000 women/year to 2.2/10,000 women/year was found only under longterm (up to 8 years) of OC use. An epidemiological investigation of 47,000 women using OCs for up to 10 years concluded that there was significant increase of frequency of cervical cancer compared with nonusers. It was 4 times higher in those taking OCs for over 10 years, although longterm use reduced uterine and ovarian cancer. Adenomatous hyperplasia of the endocervix was 14 times more frequent in OC users. In a sample of 128 women, 44% of whom were OC users, 24% had microglandular hyperplasia. Under the use of the 3-phase preparation Trisiston for 6 months-1 year ectopia was diagnosed in 13.6% of women that disappeared after cessation of use. Early cancer and dysplasia disappeared in 1/3 of women taking Enovid for 6-30 months after diagnosis. OCs promote the prophylaxis against genital cancer because women taking OCs undergo gynecological and cytological examinations more often, thus precancerous changes can be diagnosed early. The optimal and the safest method of contraception has to be chosen to minimize the effect on the cervix. PMID:1789353

  2. Cancer cervix?: a retrospective study

    International Nuclear Information System (INIS)

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

  4. Effects of radiotherapy on immunity in patients with cured localized carcinoma of the cervix uteri

    International Nuclear Information System (INIS)

    The effects of radiotherapy on immune status in patients with localized carcinoma of the cervix have been assessed serially up to 5 years remission by a wide range of methods. Neutrophil function and serum immunoglobulins were essentially normal throughout. Peripheral blood neutrophil and lymphocyte counts and the proportions of T and B-cells fell with treatment but were all normal at 5 years, with the exception of B-cell proportions which remained significantly low. Marked deterioration was seen in in vivo cellular immune responses and this persisted even at 5 years remission. Reduced in vitro immunoreactivity is not therefore a reliable marker of disease recurrence and persisting defects in cellular immunity after radiotherapy do not seem to adversely affect the host tumor response. However, in three of the six patients who subsequently relapsed after therapy, subnormal PHA lymphocyte transformation responses were observed at presentation; all patients achieving sustained remission had normal pretreatment responses

  5. Prognostic implication of apoptosis and angiogenesis in cervical uteri cancer

    International Nuclear Information System (INIS)

    Purpose: A retrospective study was performed to investigate the relationship between spontaneous apoptosis and angiogenesis uterine cervix squamous cell carcinoma patients. The prognostic value of each (and both) of these biologic parameters was also tested. Methods and Materials: The pathologic materials of 40 cervical uteri squamous cell carcinoma patients were examined and immunohistochemically stained to determine the tumor angiogenesis (tumor microvascular score), using factor VIII-related antigen, and their tumor apoptotic index (AI), using the TdT-mediated dUTP nick end-labeling (TUNEL) method. Three patients were Stage I, 18 were Stage II, 15 were Stage III, and 4 were Stage IV (FIGO classification). All patients were treated with radical radiotherapy and all had follow-up for more than 2 years. Results: The mean AI was 15.1 ± 12.8, with a median of 8.3. The mean tumor microvascular score was 3 9.7 ± 14.4, with a median of 3 8. The patients' age and tumor grade did not seem to significantly affect the prognosis. On the other hand, AI and angiogenesis (tumor microvascular score) were of high prognostic significance. The 3-year disease-free survival (DFS) rate for the patients having AI above the median was 78% (confidence interval [CI] 69-87%), compared to 32% (CI 22-42%) for those having AI below the median. The DFS was 18% (CI 9-27%) for patients having an angiogenesis score above the median, while it was 86% (CI 78-94%) for those patients having a score below the median. Conclusion: Determination of both tumor microvascular score and AI can identify patients with the best prognosis of 100% DFS (with low angiogenesis score and high AI). Women with a high score and low AI had the worst prognosis (DFS = 3%, CI 1-5%). Moreover, high AI can compensate partially for the aggressive behavior of tumors showing a high rate of angiogenesis.

  6. Radiation injuries of the pelvis and proximal parts of the femur after irradiation of carcinoma of the cervix uteri

    International Nuclear Information System (INIS)

    Data relating to 244 patients with carcinoma of the cervix uteri treated by intensive radiotherapy are given. Radiation injury of bone was diagnosed in 12 cases (4.9 +/- 1.4 percent). After x-ray therapy alone they were found in five of 59 patients treated (8.5 +/- 3.6 percent), and after γ-ray therapy in one of 171 cases (0.6 +/- 0.6 percent). The minimal focal dose of x-ray therapy causing radiation injury to bone was 5,000 rads. With an increase in dose, the frequency of injuries also increased. Radiation injury was found after γ-ray therapy with an absorbed dose of 7,000 rads. The radiological features of radiation injury of bones after irradiation of malignant tumors of the pelvis are increasing osteoporosis and the appearance of foci of sclerosis and osteolysis. Necrotic areas of various sizes may be formed. A fracture of the neck of the femur may be prevented in some cases by taking precautionary measures. Healing of an injured part depends on the size of the dose given. Large doses completely suppressed the reparative powers of the bone. Unlike changes that are traumatic in nature, radiation fractures of the pelvic bones and the proximal part of the femur have a mild clinical course; sometimes the patients continue to use the lower limb, simply complaining of pain that may vary in severity. Metastasization of tumors of the uterus to the pelvic bones is possible but infrequent. Metastases are usually associated with increasing pain

    Full Text Available Abstract Background Cervical ripening is a prerequisite for a normal obstetrical outcome. This process, including labor, is a painful event that shares features with inflammatory reactions where peripheral nociceptive pathways are involved. The capsaicin and heat receptor TRPV1 is a key molecule in sensory nerves involved in peripheral nociception, but little is known regarding its role in the pregnant uterus. Therefore, the aim of this study was to investigate human corpus and cervix uteri during pregnancy and labor and non-pregnant controls for the presence of TRPV1. Methods We have investigated human uterine corpus and cervix biopsies at term pregnancy and parturition. Biopsies were taken from the upper edge of the hysterotomy during caesarean section at term (n = 8, in labor (n = 8 and from the corresponding area in the non-pregnant uterus after hysterectomy (n = 8. Cervical biopsies were obtained transvaginally from the anterior cervical lip. Serial frozen sections were examined immunohistochemically using specific antibodies to TRPV1 and nerve markers (neurofilaments/peripherin. Results In cervix uteri, TRPV1-immunoreactive fibers were scattered throughout the stroma and around blood vessels, and appeared more frequent in the sub-epithelium. Counts of TRPV1-immunoreactive nerve fibers were not significantly different between the three groups. In contrast, few TRPV1-immunoreactive fibers were found in nerve fascicles in the non-pregnant corpus, and none in the pregnant corpus. Conclusion In this study, TRPV1 innervation in human uterus during pregnancy and labor is shown for the first time. During pregnancy and labor there was an almost complete disappearance of TRPV1 positive nerve fibers in the corpus. However, cervical innervation remained throughout pregnancy and labor. The difference in TRPV1 innervation between the corpus and the cervix is thus very marked. Our data suggest that TRPV1 may be involved in pain mechanisms associated with

    Neoadjuvant chemotherapy with bleomycin and Cisplastin was administered on ten patients with cervical cancer (IIB, IIIA, IIIB). On three successive days, five minutes after deep bilateral subcutaneous application of 100E Hylase in the medical surface of the lower third of the shin, 20 mg/msq of bleomycin was introduced slowly. The chemotherapeutic drug was absorbed by the lymph capillaries predominantly, and then transferred to the pelvic lymph nodes. Cisplastin was administered intravenously, at a dose of 50 mg/msq. Treatment was applied three times, third week. Remission was observed in 5 out of the 10 cases. PMID:9254558

    Full Text Available Considerando que o câncer cérvico-uterino ainda se apresenta como problema de saúde pública no Brasil e que os programas governamentais de prevenção existentes para esse câncer não alcançaram a meta estimada, visto que a cobertura e o número de atendimentos nas campanhas não atingiram um quarto do estimado na primeira campanha; e, na segunda, o alcance foi inferior à primeira, este artigo se propôs a levantar questões referentes a não adesão de muitas mulheres às campanhas. Para isso, foram ressaltadas a relevância epidemiológica para a abordagem do tema; a importância do corpo para a mulher; e as influências histórico-culturais no comportamento preventivo das mulheres. Dessa forma, foi realizado um estudo teórico descritivo, usando como fonte principal de informações dados do Ministério da Saúde e do Instituto Nacional do Câncer (INCA e como fonte de apoio livros, artigos científicos, periódicos e dissertações que abordam a temática proposta. A fim de discutir possibilidades estratégicas que possam ser eficazes para uma maior adesão feminina às campanhas preventivas, foi considerada a importância da forma de abordagem dos profissionais de saúde, salientando para que atuem correspondendo aos valores culturais apresentados pelas mulheres. Além disso, ressaltou-se a linguagem utilizada nas campanhas de prevenção do câncer do colo do útero, atentando para o fato de que conceitos transmitidos podem endossar valores culturais de abordagem do feminino que dificultam a identificação e a adesão de muitas mulheres.Cervix uteri cancer is still a public health problem in Brazil, but the governmental prevention programs that exist for this type of cancer have not reached the estimated index of covering.

    Cervix-cancer is the third most common female cancer worldwide. It is the leading cancer among Indian females with more than million new diagnosed cases and 50% mortality, annually. The high mortality rates can be attributed to late diagnosis. Efficacy of Raman spectroscopy in classification of normal and pathological conditions in cervix cancers on diverse populations has already been demonstrated. Our earlier ex vivo studies have shown the feasibility of classifying normal and cancer cervix tissues as well as responders/non-responders to Concurrent chemoradiotherapy (CCRT). The present study was carried out to explore feasibility of in vivo Raman spectroscopic methods in classifying normal and cancerous conditions in Indian population. A total of 182 normal and 132 tumor in vivo Raman spectra, from 63 subjects, were recorded using a fiberoptic probe coupled HE-785 spectrometer, under clinical supervision. Spectra were acquired for 5 s and averaged over 3 times at 80 mW laser power. Spectra of normal conditions suggest strong collagenous features and abundance of non-collagenous proteins and DNA in case of tumors. Preprocessed spectra were subjected to Principal Component-Linear Discrimination Analysis (PCLDA) followed by leave-one-out-cross-validation. Classification efficiency of ~96.7% and 100% for normal and cancerous conditions respectively, were observed. Findings of the study corroborates earlier studies and suggest applicability of Raman spectroscopic methods in combination with appropriate multivariate tool for objective, noninvasive and rapid diagnosis of cervical cancers in Indian population. In view of encouraging results, extensive validation studies will be undertaken to confirm the findings.

    Besides the information regarding his/her disease, each hospitalized cancer patient also provides the variety of data regarding his/her psychological, cultural, social, economical, genetic, constitutional and medical background. The aim of this study was to introduce a holistic approach to analysis of medical data, in this case clinical data regarding cancer of the corpus uteri. Such approach requires the collection of data regarding different aspects of the cancer patient, and after the satisfactory sample size is obtained (which should be at least five times greater than the number of examined patient characteristics), the performance of factor analysis. In this study, the authors have processed the data regarding 25 characteristics of 928 corpus uteri cancer patients treated between 1980 and 1990 at the Department for Gynecological Oncology of the University Hospital for Gynecology and Obstetrics, Zagreb, Croatia. In factor analysis, the principal components were rotated after the initial extraction (the authors recommended the use of oblimin rotation) in order to obtain better ground for interpretation of the obtained results. The next step in this approach was the stepwise exclusion of characteristics with smallest communalities according to Kaiser-Meyer-Olkin criteria, and retaining the characteristics and components with the most significant impact on the explained system variance. When the number of principal components and initial analyzed characteristics was reduced to 3-4 and 7-10, respectively, the ultimate interpretations and conclusions were made. This approach outlined some clusters of correlations between medical data which are difficult to identify using other statistical procedures, primarily the impacts of various socioeconomic and hereditary-constitutional variables on overall survival.

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

  18. The role of anaemia in the effectivity of radiation treatment of cancer of the collum uteri

    International Nuclear Information System (INIS)

    The role of anaemia is studied in 129 patients with cancer of the collum uteri subjected to combined radiation treatment by comparing data on anaemia and five years survival rates. Since prognosis as well as incidence of anaemia depend on the extend of the disorder the comparison is done for each clinical stage separately. Only in patients found in clinical III b statistical verification (p<0.001) is present witnessing that survival of anaemia patients is shorter than in the rest of the patients. Factors contributing to these differences being discussed a conclusion is drawn that it may be due to a lowered effectivity of the radiation treatment induced by the existing hypoxy. With this regard the relationship is discussed between oxygen tissue diffusion, cellular proliferation of tumors and the effect of ionizing radiation. (author)

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion: There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease.

  20. Hypoxia and metastasis in an orthotopic cervix cancer xenograft model

    International Nuclear Information System (INIS)

    Background: Hypoxia can promote tumor metastasis by mechanisms that are believed to result from changes in gene expression. The current study examined the role of putative metastatic genes regulated by cyclic hypoxia in relation to metastasis formation in orthotopic models of cervix cancer. Methods: Orthotopic tumors derived from ME180 human cervix cancer cells or from early generation human cervix cancer xenografts were exposed to cyclic hypoxic conditions during growth in vivo and tumor growth and lymphnode metastases were monitored. Expression of the chemokine receptor CXCR4 and various genes in the Hedgehog (Hh) pathway were inhibited using genetic (inducible shRNA vs CXCR4) small molecule (AMD3100) or antibody (5E1) treatment (CXCR4 and Hh genes, respectively) during tumor growth. Results: As reported previously, exposure of tumor bearing mice to cyclic hypoxia caused a reduction of tumor growth but a large increase in metastasis. Inhibition of CXCR4 or Hh gene activity during tumor growth further reduced primary tumor size and reduced lymphatic metastasis to levels below those seen in control mice exposed to normoxic conditions. Conclusion: Blocking CXCR4 or Hh gene expression are potential therapeutic pathways for improving cervix cancer treatment

    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

  7. Tumour size in cancer of the cervix

    International Nuclear Information System (INIS)

    In a randomized trial comprising 204 patients with operable cervical carcinomas stages I and II, two low-dose rates in gynaecological brachytherapy were compared. Treatment consisted of Cs-137 uterovaginal application followed by surgery (either immedidate or delayed). The results for the two dose rates have been published previously. The present paper concerns the correlation between outcome and tumour size. Tumour size was carefully estimated in two ways: by clinical examination under general anaesthesia and by measurements on the customized vaginal mould used for the brachytherapy. Ninety-one patients (45%) were classified as stage I, and 113 were classified as stage II proximal. The mean tumour size was 39 mm (range 15-64 mm). Cox's multivariate analysis indicated that the factors with a poor prognostic value were for survival: node involvement (N+) (p<0.001), large tumour size (T+) (p<0.001); for local control; N+ (p=0.0001); for metastasis and regional relapse: N+ (p<0.001) and T+ (p<0.001). Stage was not a prognostic factor over the present range in either univariate or multivariate analysis. In this series tumour size is a powerful independent prognostic factor. It is therefore suggested that for the classification of cervical cancer and the indications for surgical staging and adjuvant treatment, tumour size should be taken into account. (orig.)

    Purpose: To validate a Monte Carlo model and evaluate the dosimetric capabilities of a novel commercial CT/MR compatible Fletcher applicator for cervical cancer brachytherapy. Methods: MCNPX 2.7.0 was used to model the Fletcher CT/MR shielded applicator (FA) and 192Ir HDR source. Energy deposition was calculated with a track length estimator modified by an energy-dependent heating function. A high density polystyrene phantom was constructed with three film pockets for validation of the MCNPX model. Three planes of data were calculated with the MCNPX model corresponding to the three film planes in phantom. The planes were located 1 cm from the most anterior, posterior, and medial extents of the FA right ovoid. Unshielded distributions were calculated by modeling the shielded cells as air instead of the tungsten alloy. A third order polynomial fit to the OD to dose curve was used to convert OD of the three film planes to dose. Each film and MCNPX plane dose distribution was normalized to a point 2 cm from the center of the film plane and in a region of low dose gradient. MCNPX and film were overlaid and compared with a distance-to-agreement criterion of (±2%/±2mm). Shielded and unshielded distributions were overlaid and a percent shielded plot was created. Results: 85.2%, 97.1%, and 96.6% of the MCNPX points passed the (±2%/±2mm) criterion respectively for the anterior, lateral, and posterior film comparison planes. A majority of the points in the anterior plane that exceeded the DTA criterion were either along edges of where the film was cut or near the terminal edges of the film. The percent shielded matrices indicated that the maximum % shielding was 50%. Conclusion: These data confirm the validity of the FA Monte Carlo model. The FA ovoid can shield up to 50% of the dose in the anteroposterior direction.

    Full Text Available Neoadjuvant chemotherapy (NACT represents a promising modality apart from or radiotherapy as initial treatment of locally advanced cervical cancer. The primary objectives of NACT in the treatment of cervical cancer include improvement in tumor characteristics, to allow avoidance of radiotherapy, to prolong disease-free and overall survival, and facilitation of fertility-sparing surgery. Though several studies have shown promising results of NACT on tumor response, downstaging, decrease in local recurrence, improved progression free survival, yet its role is controversial and plenty of study results are waiting to establish its efficacy. After reviewing the available literatures in the internet, and focusing the light of our continuous 3 years experience, we have made an effort to find out the relevance of NACT in cancer cervix. NACT is feasible and produces impressive responses in cervical carcinoma, as has been demonstrated by several phase II and phase III trials. Some meta-analysis suggested that NACT followed by surgery improves overall survival compared with nonstandard radiotherapy alone.

  13. Cancer of the cervix: a training guide to promote awareness.

    Science.gov (United States)

    1997-01-01

    This 4-page training guide presents factual information and suggested community activities related to the prevention of cervical cancer in developing countries. After describing the risk factors for cervical carcinoma and possible signs of advanced disease, the guide presents the story of Maya--a woman in an arranged marriage whose husband would not permit her to seek medical care for abdominal pain and bleeding until her cervical cancer had advanced beyond treatment. Health educators are encouraged to use Maya's story as a learning tool to identify the chain of physical, social, economic, and political factors that contributed to her premature death. Audiences can be encouraged to identify links in Maya's story (e.g., not receiving a Pap test) that could have been changed to produce a different ending. It is recommended that, in low-resource communities, Pap smears be provided at least every 5 years to women over 35 years of age. Under development is a simple, inexpensive alternative to Pap tests that involves putting a vinegar solution on the cervix and examining it with the aid of a low-power magnifying tool; the vinegar causes abnormal cervical tissue to turn white.

    Troglitazone (TRO) is a peroxisome proliferator-activated receptor {gamma} (PPAR{gamma} ) agonist. TRO has antiproliferative activity on many kinds of cancer cells via G1 arrest. TRO also increases Cu{sup 2+}/Zn{sup 2+} -superoxide dismutase (CuZnSOD) and catalase. Cell cycle, and SOD and catalase may affect on radiation sensitivity. We investigated the effect of TRO on radiation sensitivity in cancer cells in vitro. Three human cervix cancer cell lines (HeLa, Me180, and SiHa) were used. The protein expressions of SOD and catalase, and catalase activities were measured at 2-10 {mu}M of TRO for 24 hours. Cell cycle was evaluated with flow cytometry. Reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate. Cell survival by radiation was measured with clonogenic assay. By 5 {mu}M TRO for 24 hours, the mRNA, protein expression and activity of catalase were increased in all three cell lines. G0- G1 phase cells were increased in HeLa and Me180 by 5 {mu}M TRO for 24 hours, but those were not increased in SiHa. By pretreatment with 5 {mu}M TRO radiation sensitivity was increased in HeLa and Me180, but it was decreased in SiHa. In Me180, with 2 {mu}M TRO which increased catalase but not increased G0-G1 cells, radiosensitization was not observed. ROS produced by radiation was decreased with TRO. TRO increases radiation sensitivity through G0-G1 arrest or decreases radiation sensitivity through catalasemediated ROS scavenging according to TRO dose or cell types. The change of radiation sensitivity by combined with TRO is not dependent on the PPAR {gamma} expression level.

  16. Accelerated hyperfractionated radiotherapy for locally advanced cervix cancer

    International Nuclear Information System (INIS)

    Purpose: A phase II trial was designed to evaluate the toxicity and outcome of patients with locally advanced cervix cancer treated with accelerated hyperfractionated radiotherapy (AHFX). Methods and Materials: In this prospective trial, AHFX doses of 1.25 Gy were administered twice daily at least 6 hours apart to a total pelvic dose of 57.5 Gy. A booster dose was then administered via either low-dose rate brachytherapy or external beam therapy to a smaller volume. All patients were accrued and treated at Peter MacCallum Cancer Institute (PMCI) between 1986 until April 1991. Results: Sixty-one eligible patients were enrolled in this protocol; 2 (3.2%) had Stage IIB; 42 (68.9%) had Stage III; 8 (13.1%) had Stage IV and 9 (14.8%) had recurrent cervical cancer. Fifty-two patients (85%) completed the planned external beam without a treatment break. Thirty patients had acute toxicity that required regular medication. One patient died of acute treatment related toxicity. Fifty-five patients received booster therapy: 45 with intrauterine brachytherapy, 6 with interstitial brachytherapy, and 4 with external beam. The median follow-up of surviving patients was 6 years. Overall 5-year survival is 27% and 5-year relapse free survival is 36%. Nineteen patients died with pelvic disease and the actuarial local control rate was 66%. There were 8 severe late complications observed in 7 patients. Seven required surgical intervention (an actuarial rate of 27%). Five patients also required total hip replacement. Conclusions: The local control rate was favorable compared with other series that have used standard fractionation, although overall survival remained similar. The severe late complication rate was high for this protocol and higher than similar protocols reported in the literature

  17. Irradiation of cancer of the uterine cervix and immunological mechanism

    International Nuclear Information System (INIS)

    The movement of lymphocytes in blood, the cellular immunity by the reaction of a tuberculin test, and the change of productivity of specific antibody by anti-DNA antibody were examined in 29 cases of cancer of the uterine cervix which had received radio therapy. Blood sedimentation rate at one hour were accelerated by irradiation. It seemed that blood sedimentation rate did not correlate with the total amount of protein in blood, and some changes should occur in blood. Lymphocytes which were celles in charge of immunity showed marked decrease by irradiation in peripheral blood. In spite of marked decrease of lymphocytes in blood, the reaction of a tuberculin test was hardly in flanced. There were various kinds of immunoglobulin which were decreased by irradiation. Above-mentioned changes were recognized similarly in the cases irradiated after the operation, in which tumor cells were extremely few. One case, in which anti-DNA antibody was positive, showed a rise in its antibody titer by irradiation. It was presumed that fall of various kinds of immunological functions by irradiation was relative one by decrease of the total number of lymphocytes, and cellular immunity to specific antibody stimulation, and antibody productivity would be preserved in various lymphatic tissues outside irradiation fields.

    Full Text Available Today, the common term metabolic syndrome encompasses visceral (abdominal obesity, glucose intolerance, type 2 diabetes mellitus (DM, hypertension, and dyslipidemia. In Europe, the rate of obesity mong the women ranges from 6 to 36 %. In the USA, 65 % of the adult population is overweight and 30 % is obese. High estrogen production in adipose tissue in patients with obesity has been established to increase the risk of cancer of the corpus uteri (CCU by 4 times as compared to that in normal weight female patients. Furthermore, obese patients are at increased risk for DM that is also a risk factor for CCU. A rise in the number of obese patients leads to the population redistribution of gynecological cancer. The increasing number of patients with gynecological cancer is overweight. This patient group has an increased risk from surgery and anesthesia, a higher incidence of postoperative complications, and delayed recovery. Laparotomy increases the duration of hospital stay and the rate of wound complications. The frequency of urologic injuries in obese patients varies between 2 and 4 %. In this patient category, the rate of damage to the large vessels or bowels has also statistically significant differences. The literature highlights a number of complications specific to patients with obesity: trocar damage to anterior abdominal wall vessels, particularly to the inferior epigastric artery, urinary bladder, as well as trocar site hernia. The authors describe their experience in treating CCU patients with metabolic syndrome at the Department of Surgery for Female Reproductive System Tumors, N. N. Blokhin Russian Cancer Research Center. They demonstrate that laparoscopic extirpation of the uterus and its appendages can be performed in patients with third-degree obesity (weighing 174 kg in Stage I CCU. It should be noted that this weight was previously regarded as an absolute contraindication to surgical treatment.

    Cancer of the cervix has the potential to be eradicated since the initiating cause is known. There was not much known about this cancer until the time of the Renaissance. In Malaysia, it is the second most common cancer among females after breast cancer. The strategies on prevention in this country are still not optimal. This article highlights the problems and also discusses the pathogenesis of this disease. The key to prevention is screening and the future is the era of molecular pap smear. PMID:23365496

    Full Text Available Synchronous malignancies are uncommon. The oncogenic viruses like Human Papilloma Virus (HPV 16 and 18 have been implicated in the development of cancers of the cervix and anal canal and an increased risk occurs in Human Immunodeficiency Virus-infected (HIV individuals. Though cervical screening for HPV infection is recommended in female patients with anal cancers, synchronous presentation of cancer cervix and anal canal is rare. We present a case of a 72-year-old lady with synchronous cancer cervix and anal canal with HPV 16 positivity by polymerase chain reaction (PCR treated with external radiotherapy, followed by brachytherapy to both the sites.

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

  7. The more frequent types of human papillomavirus in Cuban samples of cervix cancer

    International Nuclear Information System (INIS)

    Cervix cancer (UCC) is considered a sexually transmitted disease due to factors involved in its appearance and development and this infection is recognized as the main etiological agent of this entity. In Cuba this type of tumor is placed in 2nd category in incidence and in 4th place in mortality among the malignant disease affecting the female sex. The objective of present study is to determine the types of human virus papilloma (HVP) present in samples of cervix tumors in Cuban women, as well as to describe the behavior of different risk factors associated with this disease. Forty five samples of cervix cancer were analyzed and the presence of 20 types of HVP was determined by polymerase chain reaction with specific primers founding in them a 91,1% of positivity. Genotype 16 was the more prevalent, followed by the 18, 45, 31, 39, 51, 56, 59, PAP23A. The low risk type 6 and 11 weren't founded in samples. Promiscuity was the more interesting risk factor in our study. Knowledge of the viral types present in cervix cancer in our patients is very important when we approach the development and the use of prophylactic and therapeutical vaccines

    Purpose: To compare measurements of the uterus and cervix obtained with magnetic resonance imaging (MRI) and transabdominal ultrasound to determine whether ultrasound can identify the brachytherapy target and be used to guide conformal brachytherapy planning and treatment for cervix cancer. Methods and Materials: Consecutive patients undergoing curative treatment with radiation therapy between January 2007 and March 2012 were included in the study. Intrauterine applicators were inserted into the uterine canal while patients were anesthetized. Images were obtained by MRI and transabdominal ultrasound in the longitudinal axis of the uterus with the applicator in treatment position. Measurements were taken at the anterior and posterior surface of the uterus at 2.0-cm intervals along the applicator, from the external os to the tip of the applicator. Data were analyzed using Bland Altman plots examining bias and 95% limits of agreement. Results: A total of 192 patients contributed 1668 measurements of the cervix and uterus. Mean (±SD) differences of measurements between imaging modalities at the anterior and posterior uterine surface ranged from 1.5 (±3.353) mm to 3.7 (±3.856) mm, and −1.46 (±3.308) mm to 0.47 (±3.502) mm, respectively. The mean differences were less than 3 mm in the cervix. The mean differences were less than 1.5 mm at all measurement points on the posterior surface. Conclusion: Differences in the measurements of the cervix and uterus obtained by MRI and ultrasound were within clinically acceptable limits. Transabdominal ultrasound can be substituted for MRI in defining the target volume for conformal brachytherapy treatment of cervix cancer.

  9. The effect of performing corrections on reported uterine cancer mortality data in the city of São Paulo

    Full Text Available Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003, and area-level distribution based on three strategies: i using uncorrected death certificate information; ii correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively and corpus uteri (34.4 and 55.2% cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

  10. Are we justified for concomitant chemo-radiation in advanced stage cancer cervix?

    International Nuclear Information System (INIS)

    the survival rates have achieved a plateau of 30-45% at five years. Over the last decade there have been studies on the use of chemo-radiotherapy in carcinoma cervix. Over 19 randomized trials have been published addressing the issue of chemo-radiotherapy. However, heterogeneous data, poor randomization, inadequate number of patients, sub-optimal radiotherapy, non-uniform use of chemotherapeutic drugs, its sequencing and poor documentation have not yet provided the evidence to substantially alter the practice. The Cochrane and Canadian meta-analyses have to a large extent tried to address the role of concomitant chemo-radiation, but carcinoma cervix stage III accounted for only 30?35%. Moreover, evaluation with optimal radiation schedules and comparison of late toxicities still remain unanswered. What is more important is that the cisplatin is relatively inexpensive and is available worldwide. This means that cisplatin-based chemo-radiation is affordable in the developing countries where carcinoma cervix still forms the major cancer. However, the role of chemo-radiation in carcinoma cervix stage IIIB in developing countries including India still remains unexplored. With an aim to evaluate the role and benefit of chemo-radiation in- patients with cervical cancer we proposed this randomized study

  11. Radical radiotherapy for cervix cancer: The effect of waiting time on outcome

    International Nuclear Information System (INIS)

    Purpose: To assess the effect of treatment waiting time on clinical outcome for patients with cervix cancers treated with radical radiotherapy. Methods and materials: A retrospective analysis was conducted on all cervix cancer patients treated with radical radiotherapy between 1990 and 2001 at the Ottawa Regional Cancer Centre. Analyses were performed according to the three following separate definitions of waiting times: interval from start of radiotherapy to (1) date of initial biopsy (2) date of examination under anesthesia, and (3) date of radiation oncology consultation. Associations between waiting times and patient characteristics and disease control were investigated using t-tests, analyses of variance, and Cox regression analyses. Results: A total of 195 patients were studied. The vast majority of patients were treated within 5, 6, and 8 weeks of their consultation (91%), examination under anesthesia (88%), and biopsy (81%), respectively. On average, delays between initial biopsy and treatment start were greater for older patients (p = 0.025) (5.8 weeks for 70 years old) and those with smaller tumors (p 4 cm vs. 6.3 weeks for ≤4 cm). Univariate analysis revealed no adverse effect of treatment delay on tumor control. Multivariate analysis, with the inclusion of multiple prognostic tumor and treatment parameters, revealed an adverse effect of treatment delay on survival outcomes. Conclusions: Longer radiotherapy waiting times were found to be associated with diminished survival outcomes for patients treated radically for cervix cancer. The significance of this observed association requires further investigation

  13. Bladder and rectal complications following radiotherapy for cervix cancer

    International Nuclear Information System (INIS)

    One-hundred and thirty-two patients with cervix carcinoma who were treated with whole pelvis irradiation and two intracavitary applications had bladder and rectal dosimetry during brachytherapy with contrast agents placed into the bladder and rectum prior to orthogonal simulator radiographs. Doses were computer calculated at points A and B, F (bladder), R1 (rectum), and R2 (rectosigmoid). Late occurring bladder and rectal complications were graded on a severity scale of 1 to 3, and 14% had grade 2 or 3 injuries (9% developed fistulas). Statistical evaluation of the data showed that severe bladder and rectal injuries occur more commonly in stage IIIA and IIIB disease and in those receiving high external beam doses (5000 rad +). Analysis of variance tests revealed a significant correlation of brachytherapy dose to points R1 and R2 with severe rectal injuries but there was not a correlation of dose to F with bladder injuries. Nor was there correlation of injuries with dose to point A or the milligram-hour dose. We conclude that our technique for rectal dosimetry is adequate but that an improved technique of bladder dosimetry is needed. Also, when combining whole pelvis irradiation with two intracavitary applications (4000 rad to point A), the whole pelvis dose should probably not exceed 4000-4500 rad

  14. The positive and negative aspects of radiotherapy in the management of cancer therapy

    International Nuclear Information System (INIS)

    The results of radiotherapy (R) on 22,813 cancer patients (29.29% males and 49.46% females), registered at the National Cancer Center Hospital from 1962 to 1979 were evaluated on the 5-year relative survival rate (RSR). The method of treatment and number of patients treated until 1971 were as follows: 5,643 (44.7%) by surgical treatment (ST) only, 4,212 (33.4%) by ST with R, 1,644 (13.0%) by R only, and 1,130 (8.9%) by other treatments. ST was performed on cancers of the stomach, breast, cervix uteri, lung and rectum while R was used on cancers of the cervix uteri, lung, esophagus, tongue, lymphnode and reticulum cell sarcoma in a decreasing order. More than 50% of the 5-year RSR were achieved in cancers of the eye, skin, larynx and tongue treated by radical R. There were no cases cured by palliative R. The cases treated by preoperative R, combined with ST, were those of the cervix uteri; and those by postoperative R alone were cancers of the larynx, skin, cervix uteri, eye, breast and thyroid. A remarkable improvement of the 5-year RSR in R was seen in cases of surgical R using an electron beam on bladder cancer, and also in those of electron external R on cancers of the skin, lymph nodes and reticulm cell sarcoma. The high energy X-ray beam was usefull for retinoblastoma, cancers of the cervix uteri, larynx and pharynx. Although there was an increase in the number of long term survivors, this success was offset by a decline in the rate of rehabilitation to society due to radiation injury and an occurence of R-induced cancer and leukemia.

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

  16. Cancer of the cervix: Early detection and cost-effective solutions.

    2015-10-01

    Cervical cancer is known to be a preventable disease through the detection of cervical cancer precursors, historically using cytology of the cervix as the primary screening test. Over 85% of cervical cancer cases and deaths occur in low-resource countries. Alternatives to cytology have been investigated with the strongest possibilities being visual inspection with acetic acid (VIA) and HPV DNA testing. HPV DNA testing has been shown in randomized trials to be significantly more sensitive for the detection of cervical cancer precursors than either cytology or VIA. In this paper we argue that prevention really does cost less than cure, or that prevention and treatment of cancer costs less than no prevention, in effect just treatment, of cancer. The true cost savings of prevention will include a more difficult assessment of the socioeconomic savings associated with longer, healthier lives for women in their prime who have a major role in supporting their families.

    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.)

  19. The Dosimetric Consequences of Intensity Modulated Radiotherapy for Cervix Cancer: The Impact of Organ Motion, Deformation and Tumour Regression

    Science.gov (United States)

    Lim, Karen Siah Huey

    Hypothesis: In intensity modulated radiotherapy (IMRT) for cervix cancer, the dose received by the tumour target and surrounding normal tissues is significantly different to that indicated by a single static plan. Rationale: The optimal use of IMRT in cervix cancer requires a greater attention to clinical target volume (CTV) definition and tumour & normal organ motion to assure maximum tumour control with the fewest side effects. Research Aims: 1) Generate consensus CTV contouring guidelines for cervix cancer; 2) Evaluate intra-pelvic tumour and organ dynamics during radiotherapy; 3) Analyze the dose consequences of intra-pelvic organ dynamics on different radiotherapy strategies. Results: Consensus CTV definitions were generated using experts-in-the-field. Substantial changes in tumour volume and organ motion, resulted in significant reductions in accumulated dose to tumour targets and variability in accumulated dose to surrounding normal tissues. Significance: Formalized CTV definitions for cervix cancer is important in ensuring consistent standards of practice. Complex and unpredictable tumour and organ dynamics mandates daily soft-tissue image guidance if IMRT is used. To maximize the benefits of IMRT for cervix cancer, a strategy of adaptation is necessary.

We also reviewed published case reports of uterine and cervical lymphoma involving forty-one patients. We treated a case of stage IV DLBCL cervix with six cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone and intrathecal methotrexate followed by consolidation with radiotherapy. The patient showed complete response to chemotherapy. We conclude that, in advanced stage lymphoma involving uterus and cervix, combination of chemotherapy and radiotherapy is effective in short term.

  1. Locally advanced cervix cancer: chemotherapy prior to definitive surgery or radiotherapy. A single institutional experience

    International Nuclear Information System (INIS)

    Primary or neoadjuvant chemotherapy prior to definitive local therapy has potential advantages for locally advanced cervix cancer. It can down stage a cancer and allow definitive local therapy to be technically possible (surgery), or potentially more effective (radiotherapy). It can also eradicate subclinical systemic metastases. This report reviews a single institution's experience of neoadjuvant chemotherapy prior to definitive local therapy for cervix cancer over a 13-year period. One hundred and six patients were treated with this intent. The patients were analysed for their response to chemotherapy, treatment received, survival, relapse and toxicity. The chemotherapy was feasible and the majority of patients had a complete or partial response (58.5%). Eight patients did not proceed to local treatment. Forty-six patients had definitive surgery and 52 had definitive radiotherapy. The 5-year overall survival was 27% and the majority of patients died with disease. The first site of relapse was usually in the pelvis (46.2%). Late complications that required ongoing medical therapy (n = 6) or surgical intervention (n = 2) were recorded in eight patients (7.5%). On univariate analysis stage (P= 0.04), tumour size (P = 0.01), lymph node status (P=0.003), response to chemotherapy (P = 0.045) and treatment (P = 0.003) were all significant predictors of survival. On multivariate analysis, tumour size (P < 0.0001) and nodal status (P = 0.02) were significant predictors of survival. Despite the impressive responses to chemotherapy of advanced cervix cancer, there is evidence from randomized trials that it does not improve or compromise survival prior to radiotherapy. As its role prior to surgery remains unclear, it should not be used in this setting outside a prospective randomized trial. Copyright (2001) Blackwell Science Pty Ltd

  2. Sentinel-lymph node procedure in breast, uterine cervix, prostate, vulva and penile cancers: Practical methodology

    International Nuclear Information System (INIS)

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid 99mTc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

  4. Regeneration in cervix cancer after 252Cf neutron brachytherapy

    International Nuclear Information System (INIS)

    Regeneration of clonogens in human cervical cancer was assessed by the pathological evaluation of the hysterectomy specimen after intracavitary 252Cf neutron brachytherapy implants separated by varying time intervals followed by extrafascial hysterectomy. In this study, patients with bulky/barrel shaped Stage IB cervical cancers received 252Cf implants plus approximately 45 Gy of whole pelvis linear accelerator radiotherapy in approximately 25 fractions in 5 weeks followed by hysterectomy 4-6 weeks after radiotherapy. The specimens were studied grossly and microscopically for residual tumor. It was found that the fraction of positive specimens increased with elapsed time interval between implants. These findings support the hypothesis that there is repopulation of surviving clonogens with increased time interval between the implants. The observation also supports current concerns that rapid depopulation of tumor can lead to rapid repopulation, that is, rapid shrinkage of tumor can alter the physiological environment such that clonogens can rapidly regenerate

    ABSTRACT 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. PMID:23092107

    The case of a patient diagnosed with uterine cervix cancer is presented as an example of the clinical application of the radiobiological compensation method implemented at Centro Estatal de Cancerología de Durango. Radiotherapy treatment was initially modified to compensate for the chemotherapy component and, as medical complications arose during treatment delivery resulting in an 18 days gap, new compensation followed. All physical and radiobiological assumptions to calculate the Biologically Effective Dose in the external beam and brachytherapy parts of the treatment are presented. Good local control of the tumor was achieved, the theoretical tolerance limits for the organs at risk were not surpassed and the patient manifested no extensive morbidity.

  8. Radiation with cisplatin or carboplatin for locally advanced cervix cancer: the experience of a tertiary cancer centre

    International Nuclear Information System (INIS)

    Definitive treatment with concurrent cisplatin and radiation is the standard of care for locally advanced cervix cancer. The optimal management of patients with a contraindication to cisplatin has not been established. We conducted a retrospective audit of concurrent chemotherapy in a cohort of patients with locally advanced cervix cancer. All patients with locally advanced cervix cancer treated with definitive radiation were entered into a prospective database. Information regarding their demographics, stage, histology, recurrence and survival were recorded. Pharmacy records were reviewed to determine concurrent chemotherapy use. A total of 442 patients were included in the audit. Two hundred sixty-nine patients received cisplatin, 59 received carboplatin and 114 received no concurrent chemotherapy. Overall survival was significantly improved with the use of concurrent cisplatin compared with radiation alone (adjusted hazard ratio 0.53, P=0.001), as was disease-free survival and rate of distant failure. The use of carboplatin was not associated with any significant benefit in terms of overall survival or disease-free survival. The results of this audit are consistent with the known significant survival benefit with concurrent cisplatin chemotherapy. However, there did not appear to be any significant benefit with carboplatin although there were potential confounding factors. The available evidence in the literature would favour the use of non-platinum chemotherapy rather than carboplatin in patients with contraindications to cisplatin.

    International Nuclear Information System (INIS)

    Cancer of the cervix is the third leading cause of cancer in the Philippines. The Department of Radiotherapy of the Jose R. Reyes Memorial Medical Center has participated in the Regional Coordinated Research project sponsored by the International Atomic Energy Agency (IAEA) to undertake a study to compare computer treatment planning and manual calculations in radiotherapy of the cancer of the cervix; and to perform actual measurements on bladder and rectal points using TLDs. Twenty-seven patients with Stage II-B to III-B were included in the study. External beam teletherapy of 40 Gy without shielding for 4 weeks and 50 Gy with blocks plus brachytherapy of 20-40 Gy were given using LDR or HDR machine. Point A, bladder and rectal points were defined following ICRU 38 recommendations. The results showed dose calculations between commercially available computers and IAEA - provided computers agree to within 20%. Results of TLD measurement in bladder and rectum have shown wide range of variation. (author). 3 refs.; 4 tabs.; 8 figs

    Cervix cancer is one of common gynecological cancers in the world, and staged with FIGO or TNM system. However, these clinical staging systems lack information about lymph node or distant metastases, thus imaging modalities are considered to make an appropriate therapeutic plan and enhance overall survival rate. In this context, FDG PET is recommended to pre-treatment stating and prognosis prediction, for it could noninvasively evaluate the status of lymph nodes, especially abdominal paraaortic nodes which are closely related with prognosis. Moreover, the degree of FDG uptake is correlated with prognosis. Although there is no consistent method for surveillance of cervix cancer, FDG PET seems a very important tool in detecting tumor recurrence because it is much more advantageous than conventional imaging modalities such as MRI for discerning recurrent tumor from fibrosis caused by radiation or surgery. Furthermore, FDG PET could be used to evaluate treatment response. On the other hand, recently introduced PET/CT is expected to play an ancillary role to FIGO staging by adding anatomical information, and enhance diagnostic performance of PET by decreasing false positive findings.

    From May 1991 through September 1992, a total of 17 previously untreated patients with invasive uterine cervix cancer and with intact uterus were treated with mid-dose rate intracavitary therapy administered with a Selectron. Early primary tumor responses for all patients were complete. No acute or subacute radiation injury was observed except one patient with aplastic anemia who developed rectal ulcer. Two patients of Stage IIIb died from tumor because of local, paraaortic lymph node and distant metastases. Our early experience concluded that Selectron MDR can be used for cervix cancer patients as safely and effectively as our previously used high-dose rate machine. (author).

  12. Tissue and serum fluorescence spectroscopy as a marker to monitor radiation therapy in cancer of human uterine cervix

    The analysis of the spectral anisotropic properties of layers of oncologic modified biological tissues with precancerous condition (CIN) and with cancer formation (G) of cervix according to linear dichroism determined in the wavelength range 300-800 nm was conducted. Comparison of results of animal testing of samples of biological samples oncologic modified human tissue was conducted, introduction of differentiation criterion spectropolarimetric precancerous condition and the stage cancer formation in the spectral band of 390-410 nm was proposed. Appropriate diagnostically important changes in the value ranges of linear dichroism at each stage of cancer formation (high- and low-grade dysplasia, high and low-grade adenocarcinoma) was determined. A differential method for diagnosis of epithelial cells in the above diseases was suggested.

  15. Brachytherapy in cervix cancers: techniques and concepts evolution

    International Nuclear Information System (INIS)

    Brachytherapy plays an important role in the treatment of patients with cervical carcinoma. Technical modalities have evolved during the last years and have benefited from imaging modalities development, specially MRI. Imaging modalities contribute to a better knowledge of tumoral extension and critical organs. Ultrasound during brachytherapy has led to the almost complete eradication of uterine perforation. In the future, a more systematic use of systems allowing optimization may induce a better dose distribution in the tumor as well as in the critical organs. Recent data provided information in favor of a better analysis in the relative role of dose-rate, total dose and treated volume and their influence on the local control and complication incidence. Concomitant radio-chemotherapy represents a standard in the treatment of patients with tumoral size exceeding 4 cm. Some questions still remain: is concomitant chemotherapy of benefit during brachytherapy? Is there any place for complementary surgery, specially in patients with complete response after external irradiation with concomitant chemotherapy and brachytherapy? In order to answer the former question, a phase III randomized trial is going to start, with the Federation Nationale des Centres de Lutte Contre le Cancer as a promoter. (authors)

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

  18. Tumor regression dynamics with external radiotherapy in cancer cervix and its implications

    International Nuclear Information System (INIS)

    BACKGROUND: To study the external radiotherapy (EXTRT) regression patterns in cancer of the cervix. AIMS: Evaluate EXTRT tumor regression doses (TRD) for 50% (TRD50). 80% response (TRD80), normalized dose response gradient (γ50) and slope (slope 50) with clinical outcome. SETTINGS AND DESIGN: Patients, treated solely with radiotherapy and enrolled for other prospective studies having weekly tumor regressions recorded were considered. MATERIAL AND METHODS: Seventy-seven patients received 50Gy of EXTRT at 2 Gy/fraction followed by 18Gy of high-dose rate intracavitary brachytherapy at 6 Gy/fraction. Loco-regional regressions were assessed clinically at weekly intervals during EXTRT to generate EXTRT dose-response curves. STATISTICAL ANALYSIS USED: Student's t test, logistic regression, Kaplan Meier and Cox's proportional hazard model. Scatter plots were fitted using cubic fit. RESULTS: Age (P=0.052) and absence or presence of gross residual tumor (AGRT and PGRT respectively) following EXTRT (P50. (P80 (P50 (P=0.001). Response status to EXTRT was a prognosticator for loco-regional disease free survival (LDFS) (AGRT vs. PGRT; P=0.046). On multivariate analysis, both TRD50 and TRD80 emerged as significant predictors for tumor status at end of EXTRT while TRD80 was the sole determinant of LDFS. CONCLUSION: Extent of tumor regression to EXTRT is an important predictor for treatment outcome in cancer cervix as evident from TRD50 and TRD80 values of EXTRT tumor regression curves. (author)

    Full Text Available BACKGROUND: Cervical intra - epithelial neoplasia (CIN and cervical cancer remain important health problems for women worldwide. It is largely a preventable disease that is characterized by a long lead time. The objective of this study was to determine the frequency of precancerous lesions of cervix by Pap smear screening. METHODS : A retrospective hospital based study was conducted at Department of Pathology, in a Tertiary Care Institute and associated hospital, Bhopal. Data was collected from the records of Pap’s smear testing done on 388 patients in years 2011 & 2012. Analysis was done by entering data in SPSS software and Chi - square test was applied to find statistical significance. RESULTS: Most common lesions on Pap’s smear was Low grade squamous intraepithelial les ion (LSIL in 104 (26.8% of cases and High grade squamous intraepithelial lesion (HSIL in 15 (3.9% of cases. 44 (11.3% were senile Atopic Changes, parasitic Infection in 27 (7% of cases and 2 (0.5% were carcinoma cervix cases. All the cervical lesion s were most common in age of 31 - 40 yrs. and were significantly associated with age. CONCLUSIONS: Pap’s smear examination information should be spread in community apart from hospitals. Especially the young women should be motivated for regular Pap’s smear. Pap’s smear is the single most important screening method for early detection of precancerous & cancerous cervical lesions

    Full Text Available Background and Objective: The present study was done to analyze the immunoexpression of diagnostic markers (MIB-1: molecular immunology borstel and PCNA: proliferating cell nuclear antigen in grading cervical intraepithelial lesion (CIN and squamous cell carcinoma (SCC in cervix. Setting and Design: Total 150 cervical biopsies were divided into four groups respectively; Group I-Normal (n = 32, Group II- CIN (n = 60, Group III- SCC (n = 44, Group IV- CA cervix (n = 14 respectively. Materials and Methods: These biopsies were stained with monoclonal antibodies by streptavidin--biotin method. Mean labeling index was calculated and grading was performed using the I--III scoring system. Statistical Analysis: Findings were correlated with age and menopausal status. Statistical analysis was done by using student sample′t′ test and analysis of variance (ANOVA by SPSS 10 package. Results: MIB-1 immunostaining was positive in 112/150 (74.6% cases and PCNA in 118 /150 (78.6% cases. Labeling indices showed linear progression from normal to CIN to SCC to cancer lesion. Few cases of low-grade CIN lesion had high proliferative index. A significant positive correlation was found between age and PCNA and MIB-1 values (P < 0.05 when comparison was made for all the cases. Conclusion: These markers may be useful in identifying low-grade CIN lesion with high proliferative index. These cases should be kept for follow up studies so that proper intervention can be taken at an early stage. This method is simple and cost effective and can easily be done in formaline-fixed paraffin embedded tissues in a clinical laboratory for grading CIN and SCC lesions in cervix.

    2008-01-01

    A noninvasive optical diagnostic system for detection of cancerous and precancerous lesions of the cervix was evaluated in vivo. The optical system included a fiber-optic probe designed to measure polarized and unpolarized light transport properties of a small volume of tissue. An algorithm for diagnosing tissue based on the optical measurements was developed that used four optical properties, three of which were related to light scattering properties and the fourth of which was related to hemoglobin concentration. A sensitivity of {approx}77% and specificities in the mid 60% range were obtained for separating high grade squamous intraepithelial lesions and cancer from other pathologies and normal tissue. The use of different cross-validation methods in algorithm development is analyzed, and the relative difficulties of diagnosing certain pathologies are assessed. Furthermore, the robustness of the optical system for use by different doctors and to changes in fiber-optic probe are also assessed, and potential improvements in the optical system are discussed.

    Today around 275000 women a year in the world keep dying from the cancer of uterine cervix due to the difficulty to meet the logistic requirements of an organized screening in the developing world. Polarimetric imaging is a new promising technique with a tremendous potential for applications in biomedical diagnostics: it is sensitive to slight morphological changes in tissues, can provide wide field images for the screening and requires light sources such as a LED for example. This work intends to characterize the polarimetric response of the uterine cervix in its healthy and pathological states. An extensive series of ex-vivo measurements is in progress the Kremlin Bicêtre hospital near Paris using an imaging multispectral Mueller polarimeter in backscattering configuration. The goal of this study is to evaluate the performances of polarimetric imaging technique in terms of sensitivity and specificity for the detection of healthy epithelia (Healthy Squamous epithelium and Malpighian Metaplasia) with respect to the diagnosis provided by pathologists from histology slides as the "gold standard". We show that, at λ=550nm, performances as high as 62% sensitivity and 64% specificity are achieved by optimizing a simple threshold on the scalar retardance values.

  4. Comparison of visual inspection of cervix and pap smear for cervical cancer screening

    International Nuclear Information System (INIS)

    Objective: To evaluate the performance of visual inspection of cervix (VIA) after application of 3% acetic acid in cervical cancer screening in comparison with PAP smear. Results: Out of 540 subjects, 356 were negative with both screening techniques. One hundred and fifty-six subjects were positive with VIA (28.9%) while PAP smear was positive in seventy-eight subjects (14.4%). The sensitivity of VIA was 93.9% and of PAP smear was 46.9%. Corresponding specificities were 30.4% and 69.5%. There was no significant difference between the positive predictive value (PPV) of both test (p<0.05). The accuracy of VIA was 77.5% compared to 52.8% of PAP smear. The difference was highly significant (p < 0.01). Conclusion: These results indicate that VIA is more sensitive and has a higher accuracy as compared to PAP smear. It could, therefore, be valuable in detection of precancerous lesions of cervix. Low cost, easy applicability and immediate results make VIA a useful screening test in developing countries like Pakistan as compared to PAP smear. (author)

    Zippin, C.; Lum, D.; Kohn, H.I.; Bailar, J.C.

    1981-01-01

    This report presents follow-up information on 497 women diagnosed with cancer of the uterine cervix in Connecticut and California between 1932 and 1951 who received only radiation as their initial course of therapy. Patients entered into the study were all treated before age 55 and all were five-year-survivors following treatment in order to eliminate early deaths due to the cervical cancer. Three radiologic dosage groups (high, medium, and low) were formed with 93, 244, and 160 patients, respectively. For all dosage groups combined 108 subsequent cancers were observed more than 5 yr after cancer treatment compared with 64 expected (P less than 0.01). Sites for which subsequent cancers were significantly (P less than 0.05) in excess of expectation were rectum, ovary, lung, vulva and vagina, small intestine, oropharynx, and central nervous system excluding brain. The ratio of observed to expected cases of subsequent cancers rose only slightly with increasing radiologic dose. No significant differences in overall survival patterns for the three dosage groups were found. For all dosage groups survival was poorer than in the corresponding segment of the general population.

    Fischell, D. R.; Mazique, J. C. (Inventor)

    1981-01-01

    A cervix-to-rectum measuring device to be used in the treatment of cervical cancer is described. It includes a handle and a probe pivotably connected to the handle for insertion in the rectum. The measuring device further includes means for coupling the handle to an intrauterine radiation applicator when the latter is positioned in the uterine cervix and the probe is inserted in the rectum to pivot the handle about the probe. A gear is provided which is adapted to pivot with the probe. A pinion pivotably connected to the handle meshes with the gear. A pointer fixed to the pinion is displaced in response to the pivoting of the handle about the probe, and this displacement can be read from a scale on the handle, providing an indication of the cervix-to-rectum distance.

  7. Adjuvant postoperative radiation therapy following simple hysterectomy and radical hysterectomy in stage IB cancer of the cervix: Analysis of risk factors and patterns of failure

    International Nuclear Information System (INIS)

    Between 1969 and 1980, 242 cases of stage IB cancer of the cervix were referred to the department of radiation oncology for curative radiation therapy. In 186 cases treatment was with radiation therapy alone. In 56 cases treatment included adjuvant postoperative radiation therapy; a minimum follow-up of 5 years has been carried out in this group. In 17 cases radiation therapy followed a simple hysterectomy for an unexpected stage IB cancer of the cervix. In 39 cases radiation therapy was given after a radical hysterectomy for stage IB cancer of the cervix because of positive margins and/or positive pelvic lymph nodes

  8. Assessment with TLD of radiation exposure to staff during radium insertions in cancer of cervix

    International Nuclear Information System (INIS)

    A radiation protection survey has been carried out using TLD to assess the radiation exposure to staff during radium insertions for cancer of the cervix. The staff monitored were the radiotherapist, anaesthetist and operating theatre assistant. The radiotherapist, who received the highest exposure, had on the average 160 μGy (16 mrad) whole body (chest) dose while the finger tip doses were around 600 μGy (60 mrad) from the insertion of 60 mg radium. TLD was found to be convenient and sensitive for this purpose, including estimation of finger-tip doses. It helps to maintain the confidence of the staff that their doses are 'as low as readily achievable' and also offers a means of checking improvements in practice where found necessary. (author)

  9. Hypoxyradiotherapy of uterine cervix cancer to decrease of acute side-effects and treatment complications

    International Nuclear Information System (INIS)

    The authors have reported on preliminary results of hypoxyradiotherapy in the course of external irradiation in patients with uterine cervix cancer from a view-point of the occurrence of acute reactions and treatment complications. A mixture of nitrogen and oxygen containing 8.0 to 8.5% of O2 was used to provoke acute hypoxia during irradiation. The applied dosis of external irradiation was simultaneously increased by 40%. On the basis of a randomized study with 120 patients, acute hypoxia was found to protect healthy tissues against post-radiation damage. When the dosis of 96 Gy in the paracervical space and that of 75 Gy in the pelvic wall were applied, acute side-effects decreases significantly if compared with a conventional radiotherapeutic procedure (p<0.01). Radiological preconditions for using acute hypoxia in radiotherapy are discussed. (orig.)

  10. Hybrid adaptive radiotherapy with on-line MRI in cervix cancer IMRT

    International Nuclear Information System (INIS)

    Purpose: Substantial organ motion and tumor shrinkage occur during radiotherapy for cervix cancer. IMRT planning studies have shown that the quality of radiation delivery is influenced by these anatomical changes, therefore the adaptation of treatment plans may be warranted. Image guidance with off-line replanning, i.e. hybrid-adaptation, is recognized as one of the most practical adaptation strategies. In this study, we investigated the effects of soft tissue image guidance using on-line MR while varying the frequency of off-line replanning on the adaptation of cervix IMRT. Materials and method: 33 cervical cancer patients underwent planning and weekly pelvic MRI scans during radiotherapy. 5 patients of 33 were identified in a previous retrospective adaptive planning study, in which the coverage of gross tumor volume/clinical target volume (GTV/CTV) was not acceptable given single off-line IMRT replan using a 3 mm PTV margin with bone matching. These 5 patients and a randomly selected 10 patients from the remaining 28 patients, a total of 15 patients of 33, were considered in this study. Two matching methods for image guidance (bone to bone and soft tissue to dose matrix) and three frequencies of off-line replanning (none, single, and weekly) were simulated and compared with respect to target coverage (cervix, GTV, lower uterus, parametrium, upper vagina, tumor related CTV and elective lymph node CTV) and OAR sparing (bladder, bowel, rectum, and sigmoid). Cost (total process time) and benefit (target coverage) were analyzed for comparison. Results: Hybrid adaptation (image guidance with off-line replanning) significantly enhanced target coverage for both 5 difficult and 10 standard cases. Concerning image guidance, bone matching was short of delivering enough doses for 5 difficult cases even with a weekly off-line replan. Soft tissue image guidance proved successful for all cases except one when single or more frequent replans were utilized in the difficult cases

    To evaluate acute toxicities in cervix cancer patients receiving intensity modulated whole pelvic radiation therapy (IM-WPRT). Between August 2004 and April 2006, 17 patients who underwent IM-WPRT were analysed. An intravenous contrast agent was used for radiotherapy planning computed tomography (CT). The central clinical target volume (CTV) included the primary tumor, uterus, vagina, and parametrium. The nodal CTV was defined as the lymph nodes larger than 1 cm seen on CT and the contrased-enhanced pelvic vessels. The planning target volume (PTV) was the 1-cm expanded volume around the central CTV, except for a 5-mm expansion from the posterior vagina, and the nodal PTV was defined as the nodal CTV plus a 1.5 cm margin. IM-WPRT was prescribed to deliver a dose of 50 Gy to more than 95% of the PTV. Acute toxicity was assessed with common toxicity criteria up to 60 days after radiotherapy. Grade 1 nausea developed in 10 (58.9%) patients, and grade 1 and 2 diarrhea developed in 11 (64.7%) and 1 (5.9%) patients, respectively. No grade 3 or higher gastrointestinal toxicity was seen. Leukopenia, anemia, and thrombocytopenia occurred in 15 (88.2%). 7 (41.2%), and 2 (11.8%) patients, respectively, as hematologic toxicities. Grade 3 leukopenia developed in 2 patients who were treated with concurrent chemoradiotherapy. IM-WPRT can be a useful treatment for cervix cancer patients with decreased severe acute toxicities and a resultant improved compliance to whole pelvic irradiation.

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

  14. Using the Computed Tomography in Comparison to the Orthogonal Radiography Based Treatment Planning in High dose Rate (HDR) Brachytherapy in Cervical Uteri Cancer Patients; A Single Institution Feasibility Study

    International Nuclear Information System (INIS)

    Brachytherapy is an integral part in the treatment of cervical uteri cancer patients. Orthogonal treatment planning is the standard mode of calculation based on reference points. Introduction of the innovative 3-D computer based treatment planning allows accurate calculation based on volumetric information as regards the target volume and organs at risk (OAR). Also provide dose volume histogram (DVH) for proper estimation of the dose in relation to the volume. Aim: To correlate and compare the information obtained from the two approaches for high dose rate brachytherapy of cervical uteri cancer; the orthogonal conventional method and the computerized tomography (CT) three dimensions (3D) based calculation method in relation to the target and organ at risk (OAR). Methods: From 6 patients of cervical uteri cancer, 21 applications with orthogonal planning using the Brachy Vision treatment planning system version 7.3.10 were performed. In 10 applications; comparison between orthogonal and CT based planning was done. In orthogonal planning; the dose to point A, rectum and bladder were defined according to the American Brachytherapy Society (ABS) recommendation. From the CT based planning the target volume and dose volume histogram (DVH) were calculated for the clinical target volume (CTV), rectum and bladder. From these two sets, information was obtained and compared and mean values were derived. Results: For dose prescription at point A, an average of 63.5% of CTV received the prescribed dose. The mean ICRU dose to the bladder point is 2.9 Gy±l .2 SD (Standard Deviation) and 17% of the bladder volume derived from CT was encompassed by 2.9 Gy isodose line. The mean ICRU dose at the rectum point is 3.4 Gy±1.2 SD and 21% of the rectum volume from CT was encompassed by 3.4 Gy isodose line. The maximum dose to the rectum and the bladder derived from the CT and compared to the maximal dose at ICRU is 1.7 and 2.8 times higher than the orthogonal reference points; with the

    Uterine cervix cancer is one of the most prevalent women cancer in Korea. We analysed published papers in Korea with comparing Patterns of Care Study (PCS) articles of United States and Japan for the purpose of developing and processing Korean PCS. We searched PCS related foreign-produced papers in the PCS homepage (212 articles and abstracts) and from the Pub Med to find Structure and Process of the PCS. To compare their study with Korean papers, we used the internet site 'Korean Pub Med' to search 99 articles regarding uterine cervix cancer and radiation therapy. We analysed Korean paper by comparing them with selected PCS papers regarding Structure, Process and Outcome and compared their items between the period of before 1980's and 1990's. Evaluable papers were 28 from United States, 10 from the Japan and 73 from the Korea which treated cervix PCS items. PCS papers for United States and Japan commonly stratified into 3 {approx} 4 categories on the bases of the scales characteristics of the facilities, numbers of the patients, doctors. Researchers restricted eligible patients strictly. For the process of the study, they analysed factors regarding pretreatment staging in chronological order, treatment related factors, factors in addition to FIGO staging and treatment machine. Papers in United States dealt with racial characteristics, socioeconomic characteristics of the patients, tumor size (6), and bilaterality of parametrial or pelvic side wall invasion (5), whereas papers from Japan treated of the tumor markers. The common trend in the process of staging work-up was decreased use of lymphangiogram, barium enema and increased use of CT and MRI over the times. The recent subject from the Korean papers dealt with concurrent chemoradiotherapy (9 papers), treatment duration (4), tumor markers (8) and unconventional fractionation.

  18. Simultaneous compensation for after- irradiation in the treatment of cervix cancer

    International Nuclear Information System (INIS)

    The combined radiation therapy which consists of the intracavitary radium application and external compensatory irradiation has been established in Yonsei Cancer Center. 149 cases received radium application among the total 355 patients of cervix cancer, which had been treated by irradiation from Oct. 1969 to Dec.1972 are examined for the tumor dose on each point by Ernst radium application method. Point A; 5625 rads, Point B; 1864 rads, Co; 8375 rads. These data suggest that the metastatic lymph nodes absorbed insufficient dose from the radium treatment only and proportional irregularity of dose distribution on each point. The pattern of radium arrangement was classified in 8 types as the frequency of use in the selected cases and the above facts were established by the experimental study. And then, for delivery of cancer lethal dose in the primary site and involved pelvic lymphatics simultaneously, the total cancercidal dose was estimated as; Point A; 8,000-9,000 rads, Point B; 5,500-6,000 rads, Co: 12,000-15,000 rads. The compensating devices in accordance with 8 types of radium arrangement are made, to correct the irregularity of estimated tumor dose on each point when external compensatory Co-60 irradiation is done, after-radium irradiation. Details are given of how the treatment is planned and applied. The result as so far obtained are gratifying

    It is well known that cancer patients receiving similar radiotherapy treatments differ widely in normal tissue reactions ranging from undetectable to unacceptably severe levels. Therefore, an important goal of radiobiological research is to establish a test which would allow identifying individual radiosensitivity of patients prior to radiotherapy. The aim of the presented study is to assess the relationship between lymphocyte intrinsic radiosensitivity in vitro and early reaction of normal tissue in cervix cancer patients treated by radiotherapy. The following endpoints are analyzed in vitro: frequency of micronuclei, the kinetics of DNA repair and apoptosis. Acute normal tissue reaction to radiotherapy in the skin, bladder and rectum are scored according to the EORTC/RTOG scale. Our results show a wide inter-individual variability in chromosomal radiosensitivity in vitro. The majority of patients show a Grade 0, 1 or 2 reaction for all organs studied. No statistically significant correlation has been observed between the in vitro results in lymphocytes and the degree of early normal tissue and organ reaction.

  2. The Differentially Expressed Genes by Radiotherapy in the Patients with Uterine Cervix Cancer

    International Nuclear Information System (INIS)

    Purpose : To detect differentially expressed genes in the patients with uterine cervical cancer during the radiation therapy. Materials and Methods : In patients with biopsy proven uterine cervical cancer, we took a tumor tissue just before radiation therapy and at 40 minutes after external irradiation of 1.8 Gy. Total RNAs isolated from non-irradiated and irradiated tumor tissue samples were analyzed using the differential-display reverse transcription-polymerase chain reaction (DDRT-PCR). Complementary DNA (cDNA) fragments corresponding to differentially expressed messenger RNAs(mRNAs) were eluted, and cloned. The differential expression of the corresponding mRNAs was confirmed by reverse northern blot. Differentially expressed cDNA bands were sequenced. Nucleotide sequence data were analyzed in the Gene Bank and EMBL databases via the BLAST network server to identify homologies to known genes or cDNA fragments. Expression pattern of down-regulated clone was examined using RT-PCR in 5 patients undergoing radiotherapy. Results : We identified 18 differentially expressed bands by DDRT-PCR, which were eluted and cloned. There were 10 up-regulated clones and 1 down-regulated clone in reverse northern blot. One cDNA fragment had homology to chemokine receptor CXCR4, four were identified as Human ESTs in the EMBL database in EST clones. Down-regulated CxCa-11 was also down regulated in all patients. Conclusion : Using the DDRT-PCR, we have identified 10 up-regulated and 1 down-regulated clone(s) in the patients with uterine cervix cancer during the radiation therapy. The clinical relevance and the functions of these genes will be further investigated

    2015-02-01

    Full Text Available Introduction: The burden of cervical cancer is large and growing in developing countries, due in large part to limited access to screening services and lack of human papillomavirus (HPV vaccination. In spite of modern advances in diagnostic and therapeutic modalities, outcomes from cervical cancer have not markedly improved in recent years. Novel clinical trials are urgently needed to improve outcomes from cervical cancer worldwide. Methods: The Cervix Cancer Research Network (CCRN, a subsidiary of the Gynecologic Cancer InterGroup (GCIG, is a multi-national, multi-institutional consortium of physicians and scientists focused on improving cervical cancer outcomes worldwide by making cancer clinical trials available in low-, middle-, and high-income countries. Standard operating procedures for participation in CCRN include a pre-qualifying questionnaire to evaluate clinical activities and research infrastructure, followed by a site visit. Once a site is approved, they may choose to participate in one of four currently accruing clinical trials.Results: To date, 13 different CCRN site visits have been performed. Of these 13 sites visited, 10 have been approved as CCRN sites including Tata Memorial Hospital, India; Bangalore, India; Trivandrum, India; Ramathibodi, Thailand; Siriaj, Thailand; Pramongkutklao, Thailand; Ho Chi Minh, Vietnam; Blokhin Russian Cancer Research Center; the Hertzen Moscow Cancer Research Institute; and the Russian Scientific Center of Roentgenoradiology. The four currently accruing clinical trials are TACO, OUTBACK, INTERLACE, and SHAPE.Discussion: The CCRN has successfully enrolled 10 sites in developing countries to participate in four randomized clinical trials. The primary objectives are to provide novel therapeutics to regions with the greatest need and to improve the validity and generalizability of clinical trial results by enrolling a diverse sample of patients.

  5. Clinical experience of Sheriproct suppository to rectitis due to radiotherapy of cancer of the uterine cervix

    International Nuclear Information System (INIS)

    The subject was 30 cases of cancer of the uterine cervix, which were composed of 13 cases of acute rectitis and 17 cases of delayed rectitis due to radiotherapy. Out of them, 25 cases were treated with radiation, alone and 5 cases were treated with postoperative irradiation. The acute cases were administered Sheriproct alone twice a day (in the morning and in the evening) until symptoms disappeared. The delayed cases were administered two or three suppositories per a day together with antihemorrhagics for one to three weeks, decreasing the administration dose according to severity of symptoms. In the delayed cases, this suppository showed effectiveness in prolapsed hemorrhoids with a recovery rate of 88.9%, and it showed effectiveness in a pain with that of 71.4%. However, this depository showed ineffectiveness in hemorrhage, inhibition of mucous stool, and inhibition of secrete, and these symptoms were generally resistant to this suppository. On the other hand, in the acute cases, this suppository showed ineffectiveness only in prolapsed hemorrhoids with a recovery rate of 63.3%, and it showed marked effectiveness in hemorrhage with that of 100%. It also showed effectiveness in a pain, inhibition of mucose stool, and inhibition of secrete. These symptoms responded well to this suppository. Consequently, use of this drug seemed to be significant in making it possible to perform radiotherapy. (Kanao, N.)

    International Nuclear Information System (INIS)

    Purpose: To investigate the efficacy of oral misoprostol administered to facilitate tandem application to the cervix as a part of brachytherapy in patients with cervical cancer. Methods and Materials: Eighty patients with cervical cancer who had been planned to undergo brachytherapy at Dr. Luetfi Kirdar Kartal Training and Research Hospital were evaluated in a double-blind, prospective, randomized trial. Patients were divided randomly into two groups of 40 patients. The first and second groups received 400 μg of misoprostol orally and placebo, respectively, 3 h before tandem application. The two groups were compared in terms of age, diameter of tumor, parity, age at first intercourse, amount of bleeding and pain at first tandem application, length of endometrial cavity measured by hysterometer, and size of Hegar dilators used for cervical dilatation. Results: Of all cases, 63.6%, 16.3%, 10%, 6.3%, 2.5%, and 1.3% were Stage IIB, IIIB, IIIA, IVA, IIA and IIC, respectively. Mean (±SD) age (range) was 49.3 ± 13.1 (25-83) years and 56.6 ± 13.2 (30-78) years in the study and control groups, respectively (p = 0.015). Age at first intercourse, diameter of tumor, parity, amount of bleeding at first tandem application, and length of endometrial cavity measured by hysterometer were not significantly different between the two groups. Pain score was significantly higher in the control group (p < 0.001). Application was significantly easier in the study group compared with controls (p < 0.001). Average size of initial Hegar dilators used for cervical dilatation was significantly higher in the study group compared with controls (p = 0.017). Conclusion: Administration of misoprostol 400 μg orally for cervical ripening before tandem application facilitates the procedure, increases patient tolerability and comfort, and may decrease complication rates.

    Full Text Available AIM: This research has aimed to determine knowledge and practice status of nurses about breast self-examination (BSE, clinical breast examination (CBE, mammography and Pap smear and about influencing status of some variables related to these examinations. METHOD: This descriptive study was conducted in an education hospital in Ankara between March 1st and May 30th, 2008. Three hundred-fifty nurses (82.7% have accepted to participate in the study. Data were collected by a questionnaire form including questions about demographics, their knowledge and practice status about BSE, CBE, mammography and Pap smear. Chi-square test, numbers and percentages were used for evaluating the data. RESULTS: Overall, 46.9% of nurses had enough knowledge about early diagnosis of breast and cervix cancer. 60.2% of them can carry BSE, 18.8% can carry out CBE and 7.3% can carry out mammography. Pap smear is carried out by 23.7% of the nurses. Negligence, fear of cancer and thought of finding them unnecessary were determined as reasons for avoidance. Their knowledge and practice were significantly different (p<0.05 according to their age and service where they work. CONCLUSION: It has been concluded that although knowledge and practices of nurses on breast and cervix cancer are at a good level, this isn’t enough when importance of early diagnosis in breast and cervix cancer are taken into consideration, which are among common cancers in women.

However, its dose from brachytherapy (BT) is not systematically reported as in other OARs, even with image-guided brachytherapy (IGBT). This study aims to introduce consideration of quantified objectives for SB in BT plan optimization and to evaluate the feasibility of sparing SB while maintaining adequate target coverage. In all, 13 patients were included in this retrospective study. All patients were treated with external beam radiotherapy (EBRT) 45Gy in 25 fractions followed by high dose rate (HDR)-BT boost of 28Gy in 4 fractions using tandem/ring applicator. Magnetic resonance imaging (MRI) and computed tomographic (CT) images were obtained to define the gross tumor volume (GTV), high-risk clinical target volume (HR-CTV) and OARs (rectum, bladder, sigmoid colon, and SB). Treatment plans were generated for each patient using GEC-ESTRO recommendations based on the first CT/MRI. Treatment plans were revised to reduce SB dose when the [Formula: see text] dose to SB was > 5Gy, while maintaining other OAR constraints. For the 7 patients with 2 sets of CT and MRI studies, the interfraction variation of the most exposed SB was analyzed. Plan revisions were done in 6 of 13 cases owing to high [Formula: see text] of SB. An average reduction of 19% in [Formula: see text] was achieved. Meeting SB and other OAR constraints resulted in less than optimal target coverage in 2 patients (D90 of HR-CTV < 77Gyαβ10). The highest interfraction variation was observed for SB at 16 ± 59%, as opposed to 28 ± 27% for rectum and 21 ± 16% for bladder. Prospective reporting of SB dose could provide data required to establish a potential correlation with radiation-induced late complication for SB. PMID:26235549

  11. Early diffusion weighted magnetic resonance imaging can predict survival in women with locally advanced cancer of the cervix treated with combined chemo-radiation

    International Nuclear Information System (INIS)

    To assess the predictive value of diffusion weighted imaging (DWI) for survival in women treated for advanced cancer of the cervix with concurrent chemo-radiotherapy. Twenty women treated for advanced cancer of the cervix were recruited and followed up for a median of 26 (range -3/mm2/s), respectively, P = 0.02. The median change in ADC 14 days after treatment commencement was significantly higher in the alive group compared to non-survivors, 0.28 and 0.14 (x 10-3/mm2/s), respectively, P = 0.02. There was no evidence of a difference between survivors and non-survivors for pretreatment baseline or post-therapy ADC values. Functional DWI early in the treatment of advanced cancer of the cervix may provide useful information in predicting survival. (orig.)

    Full Text Available Serum fucose levels and fucosyl transferase activities have been designated as nonspecific markers of malignancy, and play an important role in the diagnosis of different types of malignancies. In the present study, attempts were made to determine the prognostic significance of these markers in patients with cancer of the uterine cervix after therapy. It was found that both serum fucose and fucosyl transferase, which were elevated in untreated patients declined significantly in patients responsive to therapy at different follow-up intervals, but not in patients unresponsive to therapy.

    Adaptive radiation therapy (ART) had been proposed to restore dosimetric deficiencies during treatment delivery. In this paper, we developed a technique of Geometric reLocation for analyzing anatomical OBjects' Evolution (GLOBE) for a numerical model of tumor evolution under radiation therapy and characterized geometric changes of the target using GLOBE. A total of 174 clinical target volumes (CTVs) obtained from 32 cervical cancer patients were analyzed. GLOBE consists of three main steps; step (1) deforming a 3D surface object to a sphere by parametric active contour (PAC), step (2) sampling a deformed PAC on 642 nodes of icosahedron geodesic dome for reference frame, and step (3) unfolding 3D data to 2D plane for convenient visualization and analysis. The performance was evaluated with respect to (1) convergence of deformation (iteration number and computation time) and (2) accuracy of deformation (residual deformation). Based on deformation vectors from planning CTV to weekly CTVs, target specific (TS) margins were calculated on each sampled node of GLOBE and the systematic (Σ) and random (σ) variations of the vectors were calculated. Population based anisotropic (PBA) margins were generated using van Herk's margin recipe. GLOBE successfully modeled 152 CTVs from 28 patients. Fast convergence was observed for most cases (137/152) with the iteration number of 65 ± 74 (average ± STD) and the computation time of 13.7 ± 18.6 min. Residual deformation of PAC was 0.9 ± 0.7 mm and more than 97% was less than 3 mm. Margin analysis showed random nature of TS-margin. As a consequence, PBA-margins perform similarly to ISO-margins. For example, PBA-margins for 90% patients' coverage with 95% dose level is close to 13 mm ISO-margins in the aspect of target coverage and OAR sparing. GLOBE demonstrates a systematic analysis of tumor motion and deformation of patients with cervix cancer during radiation therapy and numerical modeling of PBA-margin on 642 locations of CTV

  15. MRI-assisted cervix cancer brachytherapy pre-planning, based on application in paracervical anaesthesia: final report

    International Nuclear Information System (INIS)

    Optimal applicator insertion is a precondition for the success of cervix cancer brachytherapy (BT). We aimed to assess feasibility and efficacy of MRI-assisted pre-planning, based on applicator insertion in para-cervical anaesthesia (PCA). Five days prior to BT, the pre-planning procedure was performed in 18 cervix cancer patients: tandem-ring applicator was inserted under PCA, pelvic MRI obtained and applicator removed. Procedure tolerability was assessed. High risk clinical target volume (HR CTV) and organs at risk were delineated on the pre-planning MRI, virtual needles placed at optimal positions, and dose planning performed. At BT, insertion was carried out in subarachnoidal anaesthesia according to pre-planned geometry. Pre-planned and actual treatment parameters were compared. Pre-planning procedure was well tolerated. Median difference between the pre-planned and actual needle insertion depth and position were 2 (0–10) mm and 4 (0–30) degrees, respectively. The differences between the pre-planned and actual geometric and dosimetric parameters were statistically non-significant. All actual needles were positioned inside the HR CTV and outside the organs at risk (OAR). Our pre-planning approach is well tolerated and effective. Pre-planned geometry and dose distribution can be reproduced at BT

  16. Uncertainties of target volume delineation in MRI guided adaptive brachytherapy of cervix cancer: A multi-institutional study

    International Nuclear Information System (INIS)

    Background and aim: We aimed to quantify target volume delineation uncertainties in cervix cancer image guided adaptive brachytherapy (IGABT). Materials and methods: Ten radiation oncologists delineated gross tumour volume (GTV), high- and intermediate-risk clinical target volume (HR CTV, IR CTV) in six patients. Their contours were compared with two reference delineations (STAPLE-Simultaneous Truth and Performance Level Estimation and EC- expert consensus) by calculating volumetric and planar conformity index (VCI and PCI) and inter-delineation distances (IDD). Results: VCISTAPLE and VCIEC were 0.76 and 0.72 for HR CTV, 0.77 and 0.68 for IR CTV and 0.59 and 0.58 for GTV. Variation was most prominent caudally and cranially in all target volumes and posterolaterally in IR CTV. IDDSTAPLE and IDDEC for HR CTV (3.6 ± 3.5 and 3.8 ± 3.4 mm) were significantly lower than for GTV (4.8 ± 4.2 and 4.2 ± 3.5 mm) and IR CTV (4.7 ± 5.2 and 5.2 ± 5.6 mm) (p < 0.05). Conclusions: Due to lower delineation uncertainties when compared to GTV and IR CTV, HR CTV may be considered most robust volume for dose prescription and optimization in cervix cancer IGABT. Adequate imaging, training and use of contouring recommendations are main strategies to minimize delineation uncertainties

  18. Investigation of rectal complication after RALS-therapy for uterine cervix cancer using multivariate analysis

    International Nuclear Information System (INIS)

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

    A clinical treatment delivery platform has been developed and is being evaluated in a clinical pilot study for providing 3D controlled hyperthermia with catheter-based ultrasound applicators in conjunction with high dose rate (HDR) brachytherapy. Catheter-based ultrasound applicators are capable of 3D spatial control of heating in both angle and length of the devices, with enhanced radial penetration of heating compared to other hyperthermia technologies. Interstitial and endocavity ultrasound devices have been developed specifically for applying hyperthermia within HDR brachytherapy implants during radiation therapy in the treatment of cervix and prostate. A pilot study of the combination of catheter based ultrasound with HDR brachytherapy for locally advanced prostate and cervical cancer has been initiated, and preliminary results of the performance and heating distributions are reported herein. The treatment delivery platform consists of a 32 channel RF amplifier and a 48 channel thermocouple monitoring system. Controlling software can monitor and regulate frequency and power to each transducer section as required during the procedure. Interstitial applicators consist of multiple transducer sections of 2-4 cm length × 180 deg and 3-4 cm × 360 deg. heating patterns to be inserted in specific placed 13g implant catheters. The endocavity device, designed to be inserted within a 6 mm OD plastic tandem catheter within the cervix, consists of 2-3 transducers × dual 180 or 360 deg sectors. 3D temperature based treatment planning and optimization is dovetailed to the HDR optimization based planning to best configure and position the applicators within the catheters, and to determine optimal base power levels to each transducer section. To date we have treated eight cervix implants and six prostate implants. 100 % of treatments achieved a goal of >60 min duration, with therapeutic temperatures achieved in all cases.

    Full Text Available Background: Objectives of current study were to evaluate visual inspection of cervix with acetic acid in picking up abnormal cervix and to correlate the findings of VIA with Pap smear, colposcopy and cervical biopsy. Methods: Study was conducted on 300 sexually active women attending the gynaecological OPD at Dayanand medical college and hospital, Ludhiana. All patients underwent VIA and Pap smear screening and if either of the two was abnormal, colposcopy was done and colposcopic guided cervical biopsy was taken if indicated. Total 105 colposcopies were done. Cervical biopsy was taken in 87 cases and the results were compared and statistically analysed. Results: The sensitivity of VIA was 86% and specificity 40.50%. No case was missed by VIA when cut off was taken as moderate dysplasia or higher lesions on biopsy. Conclusions: VIA is a sensitive, practical and a low cost affair in cervical cancer screening.

    Full Text Available Background: There is limited information on population-based cancer survival data in Latin America.Objetive: To obtain estimates of survival for some cancers recognized as a public health priority in Colombia using data from the Cancer Registry of Cali for 1995-2004.Methods: All cancer cases for residents of Cali were included for the following sites: breast (3,984, cervix uteri (2,469, prostate (3,999, stomach (3,442 and lung (2,170.  Five-year relative survival estimates were calculated using the approach described by Estève.Results: Five-year relative survival was 79% in patients with prostate cancer and 68% and 60% in women with breast or cervix uteri cancer, respectively. The cure fraction was 6% in subjects with lung cancer and 15% in those with stomach cancer. The probability of dying from breast or prostate cancer in people in the lower socio-economic strata (SES was 1.8 and  2.6  times greater,  respectively,  when compared to  upper SES, p <0.001. Excess mortality associated with cancer was independent of age in prostate or breast cancer.  After adjusting for age, sex and SES, the risk of dying from breast, cervix uteri, prostate and lung cancer during the 2000-2004 period decreased 19%, 13%, 48% and 16%, respectively, when compared with the period of 1995-1999. There was no change in the prognosis for patients with stomach cancer.Conclusions: Survival for some kinds of cancer improved through the 1995-2004 period, however health care programs for cancer patients in Cali are inequitable. People from lower SES are the most vulnerable and the least likely to survive. 

  2. Effectiveness of cervical conization versus simple total hysterectomy, patients with in situ cervix cancer, Instituto Oncologico Nacional Dr. Juan Tanca Marengo Guayaquil 1996-1998

    International Nuclear Information System (INIS)

    The cancer in the cervix is the main cause of oncologic disease in the women in Ecuador. This investigation tries to find out the more adequate surgical treatment used in the patients with early cervix cancer, in agreed with the cost benefit relationship. This work has not been before done in the ION SOLCA, because of that, there is only information reports of other countries. We make a bibliographic review of previous reports about the surgical treatments of the cancer in situ of the cervix, that is the cervical conization and the simple total hysterectomy, likewise, we analyse the results of the efficacy of both treatments in the patients attended during three years in the National Oncologic Institute SOLCA, by means of a 5 years follow up. In this retrospective study, it was compared the efficacy between the cervical conization and the simple total hysterectomy in the treatment of patients with in situ cancer of cervix who went to the service of surgery of the Oncologic National Institute SOLCA Guayaquil during 1996, 1997 and 1998 and whom were followed up during 5 years. This is a bibliographic documental investigation, in which, we got information about the object of study from the department of statistics in the ION SOLCA; the techniques used were the analysis and the documental statistic collection. We revised 246 clinical histories of patients with cancer in situ of cervix, of which, 128 were included and 118 were excluded. The reasons for exclusion were the lack of posttreatment controls and data record. The data collection was accomplished by formularies. The 128 clinical histories were classified in three groups: the group in which it was done only the conization. The group in which it was done only the simple total hysterectomy. The group in which it was done both treatment. (The author)

  3. Clinical impact of MRI assisted dose volume adaptation and dose escalation in brachytherapy of locally advanced cervix cancer

    International Nuclear Information System (INIS)

    Background: To investigate the clinical impact of MRI based cervix cancer brachytherapy combined with external beam radiochemotherapy applying dose volume adaptation and dose escalation in a consecutive group of patients with locally advanced cervix cancer. Methods: In the period 1998-2003, 145 patients with cervix cancer stages IB-IVA were treated with definitive radiotherapy +/- cisplatin chemotherapy. Median age was 60 years. In 67 patients, the tumour size was 2-5 cm, in 78 patients it was >5 cm. In 29 cases the standard intracavitary technique was combined with interstitial brachytherapy. Total prescribed dose was 80-85 Gy (total biologically equivalent dose in 2 Gy fractions). Since 2001, MRI based treatment planning integrated systematic concepts for High Risk Clinical Target Volume (HR CTV) and organs at risk (OAR), biological modelling, Dose-Volume-Histogram analysis, dose-volume-adaptation (D90, D 2 cm3), and dose escalation, if appropriate and feasible. Findings: Dose volume adaptation was performed in 130/145 patients. The mean D90 during the whole period was 86 Gy, with a mean D90 of 81 Gy and 90 Gy during the first and second period, respectively (p 5 cm it was 71% in 1998-2000 and 90% in 2001-2003 (p = 0.05). Progression free survival (PFS) for true pelvis (local control) was 85%, PFS for distant metastases was 80%, both at 3 years. Local control for tumours >5 cm was 64% in 1998-2000 and 82% in 2001-2003 (p = 0.09) and 100% and 96%, respectively, for tumours 2-5 cm. PFS for distant metastases remained the same during the two treatment periods with 79% and 80%. Overall survival (OS) was 58%, and cancer-specific survival (CSS) was 68% at 3 years. In the two different periods improvement in OS was from 53% to 64% (p = 0.03) and in CSS from 62% to 74% (p = 0.13). Improvement occurred only in tumours >5 cm: OS 28% versus 58% (p = 0.003); CSS 40% versus 62% (p = 0.07). Actuarial late morbidity rate (LENT SOMA, grades 3 and 4) at 3 years was

  4. Comparison of two different treatment regimens for cancer of uterine cervix as practised in our institute: a retrospective analysis

    International Nuclear Information System (INIS)

    Starting from the early days of radiotherapy practice till today, cancer of female uterine cervix is the most common malignant disease in India. A number of treatment modalities are being used for the treatment of this disease. Earlier, Wertheim's hysterectomy was the primary line of treatment. But due to poor cosmetic results and other complications, nowadays radiotherapy is the most preferred modality for the radical treatment of this commonest malignancy. Due to the lack of any universally accepted radiotherapy treatment regime, different oncology therapists within the same institute are practising different regimens derived from their own clinical practice experience. Majority of the patients are treated with two parallel opposed (AP-PA) portals up to 40 Gy, then 10 Gy dose is delivered using central shield to avoid overdose to bladder and rectum and to get dose uniformity caused by I/C application. External irradiation was delivered by a 60Co photon beam

  5. Comparison of 3D MRI with high sampling efficiency and 2D multiplanar MRI for contouring in cervix cancer brachytherapy

    International Nuclear Information System (INIS)

    MRI sequences with short scanning times may improve accessibility of image guided adaptive brachytherapy (IGABT) of cervix cancer. We assessed the value of 3D MRI for contouring by comparing it to 2D multi-planar MRI. In 14 patients, 2D and 3D pelvic MRI were obtained at IGABT. High risk clinical target volume (HR CTV) was delineated by 2 experienced radiation oncologists, using the conventional (2D MRI-based) and test (3D MRI-based) approach. The value of 3D MRI for contouring was evaluated by using the inter-approach and inter-observer analysis of volumetric and topographic contouring uncertainties. To assess the magnitude of deviation from the conventional approach when using the test approach, the inter-approach analysis of contouring uncertainties was carried out for both observers. In addition, to assess reliability of 3D MRI for contouring, the impact of contouring approach on the magnitude of inter-observer delineation uncertainties was analysed. No approach- or observer - specific differences in HR CTV sizes, volume overlap, or distances between contours were identified. When averaged over all delineated slices, the distances between contours in the inter-approach analysis were 2.6 (Standard deviation (SD) 0.4) mm and 2.8 (0.7) mm for observers 1 and 2, respectively. The magnitude of topographic and volumetric inter-observer contouring uncertainties, as obtained on the conventional approach, was maintained on the test approach. This variation was comparable to the inter-approach uncertainties with distances between contours of 3.1 (SD 0.8) and 3.0 (SD 0.7) mm on conventional and test approach, respectively. Variation was most pronounced at caudal HR CTV levels in both approaches and observers. 3D MRI could potentially replace multiplanar 2D MRI in cervix cancer IGABT, shortening the overall MRI scanning time and facilitating the contouring process, thus making this treatment method more widely employed

  6. Plasma osteopontin levels in patients with head and neck cancer and cervix cancer are critically dependent on the choice of ELISA system

    International Nuclear Information System (INIS)

    The tumor-associated glycoprotein osteopontin (OPN) is discussed as a plasma surrogate marker of tumor hypoxia and as an indicator of the presence of pleural mesothelioma in asbestos-exposed individuals. The clinical introduction of plasma OPN measurements requires the availability of a reliable enzyme-linked immunosorbence assay (ELISA). We compared previously described and currently available ELISA systems on 88 archival plasma samples obtained from patients with head and neck or cervix cancer between 20 days before and 171 after the start of radiotherapy. Median (range) plasma OPN levels were 667 (148.8–2095) ng/ml and 9.8 (3.5–189.5) ng/ml for a previously described and a newly marketed assay, respectively. Although results for different assays were significantly correlated (r = 0.38, p < 0.05, Spearman rank test), between-assay factors ranged from 2.0 to 217.9 (median 74.6) in individual patients. OPN levels in cervix cancer patients were comparable to those of head and neck cancer patients. Commercially available OPN ELISA systems produce different absolute plasma OPN levels, compromising a comparison of individual patient data with published results. However, different assays appear to have a similar capacity to rank patients according to plasma OPN level. A review of literature data suggests that plasma OPN levels measured even with identical ELISA systems can only be compared with caution

  8. Radiotherapy results of uterine cervix cancer stape IIB : overall survival, prognostic facters, patterns of failure and late complications

    International Nuclear Information System (INIS)

    Treatment of choice for uterine cervix cancer stage IIB is radiotherapy. We analyzed survivals, prognostic factors, patterns of failure and complications. This is a retrospective analysis of 167 patients with stage IIB carcinoma of uterine cervix treated with curative external pelvic and high dose rate intracavitary radiotherapy at the Department of Therapeutic Radiology, Soonchunhyang University Hospital from August 1985 to August 1994. All the patients followed up from 3 to 141 months(mean 60 months) and age of patients ranged from 31 to 78 years at presentation(mean : 55 years). Overall complete response rate was 84%. The response rate for squamous cell carcimoma and adenocarcinoma were 86% and 60%, respectively. Overall 5-years survival rate and disease free survival rate was 62 and 59%, respectively. Mass size and treatment response were significant prognostic factors for survival. Pathologic type and parametrial involvement were marginally significants prognostic factors. Local failure was 43 cases, distant metastasis was 14 cases and local failure plus distant metastasis was 3 cases, and most of local failures occurred within 24 months, distant metastasis within 12 months after treatment. Twenty eight(16.8%) patients developed late rectal and urinary complications There were tendency to increasing severity and frequency according to increased fractional dose and total(rectal and bladder) dose. Survival rate was significantly related to tumor size and radiotherapy response. Tumor size should be considered in the clinical staging. To increased survival and local control, clinical trials such as decreasing duration of radiotherapy or addition of chemotherapy is needed. To detect early recurrence, regular follow up after RT is important. Because total rectal and bladder dose affected late complications, meticulous vaginal packing is needed to optimize dose of normal tissues and to decrease late complications

    This study reevaluated indications of postoperative radiotherapy for cancer of the uterine cervix from the viewpoint of prognosis and side effects. The subjects were 441 patients treated for clinical stage Ib or more from 1976 through 1987. According to the degree of cancer involvement, the patients were classified as cancer involvement to one third of the uterine cervix (group A), two thirds (group B), more than two thirds (group C), and the parauterine tissue (group D). Postoperative total pelvic irradiation of 40-50 Gy was given to patients with vascular involvement in groups A and B, all patients in groups C and D, and patients with lymph node (LN) metastases. Histology revealed squamous cell carcinoma (SCC) in 354 patients and adenocarcinoma or adenomatous SCC in the other 87. In LN negative SCC patients (n=268), the recurrence rate for irradiated patients was 16.7% in group A, 13.6% in group B, and 21.0% in group C; the corresponding figures for non-irradiated patients were 9.6%, 8.3%, and 50.0%, respectively. In all LN positive SCC patients treated with irradiation (n=86), it was 0% in group A, 37.5% in group B, 45.7% in group C, and 54.8% in group D. The more cancer was involved, the higher the recurrence rate was in both negative and positive SCC patients. The 5-year survival rate in LN negative SCC patients was 100% and 97.2% for irradiated and non-irradiated patients, respectively, in group A, 100% and 97.0% in group B, and 89.7% and 50.0% in group C. Postoperative irradiation seemed to be unnecessary for LN negative patients in groups A and B. In SCC patients with either musculi iliacus involvement or primary LN metastases, prognosis was independent of the presence or absence of irradiation. The incidence of edema in the lower extremities and vulva was 0% for irradiation without LN dissection, 10.2% for LN dissection without irradiation, and 51.3% for both irradiation and LN dissection.

  10. Evaluation of the effect of routine packed red blood cell transfusion in anemic cervix cancer patients treated with radical radiotherapy

    International Nuclear Information System (INIS)

    Purpose: It is well established that anemia predicts diminished radiocurability in cervix cancer. However, the therapeutic benefit of measures to correct the anemia remains controversial. The objective of this study was to determine the impact of routine transfusion in patients with hemoglobin level (hb-l) ≤11 g/dl. Methods and Materials: Since 1985, it has been departmental policy to attempt to correct hb-l ≤11 g/dl before and/or during radiotherapy by red blood cell transfusion (RBCT) in patients undergoing radical radiotherapy for primary cervix cancer. To assess the benefit of RBCT, the charts of 204 patients (FIGO: IB-IV) treated until 1997 were reviewed. Parameters analyzed for their impact on disease-specific survival (DSS), pelvic control (PC), and metastases-free survival (MFS) included pretreatment hb-l, treatment hb-l, stage, tumor size, and lymph node status. To determine any differences in outcome according to type of anemia, a separate analysis was performed, grouping patients by cause of anemia (tumor vs. other medical illness related). Results: Each of the parameters tested was significantly correlated with the end points studied in univariate analysis. Patients whose hb-l were corrected (18.5%) had an outcome that did not differ significantly from that of nontransfused patients, whereas DSS, PC, and MFS (all: p<0.001) were significantly decreased in nonresponders to RBCT. Subgroup analysis showed no impact of hb-l in patients with other medical illness-related anemia (n=12). In multivariate analysis treatment, but not pretreatment, hb-l remained predictive for DSS, PC, and MFS. Persistent anemia was associated with a significantly increased risk of death (relative risk: 2.1) and pelvic failure (relative risk: 2.4) compared with nontransfused patients. If only patients with tumor anemia were considered, the respective risks increased (2.7; 3.6). None of the patients with other causes of anemia recurred, whether or not their hb-l was maintained

    International Nuclear Information System (INIS)

    The types of treatment applied in patients with stages of cancer of cervix IB1 and IB2, your evolution and prognosis were determined. Different methods of treatment were compared. It was a prospective descriptive and observational study of the patients of Servicio de Ginecologia Oncologica of the Hospital Calderon Guardia, San Jose, Costa Rica. It was carried out from August 2000 to November 2002. The study included all female patients with proved histological diagnosis of cervical cancer IB1 and IB2. All of them had pre-operative studies: plate of thorax, abdomen ultrasound, computerized axial tomography of pelvis and abdomen, at least received primary treatment (surgery) and the following monitoring. The statistical analysis was realized with chi-square evidences, through epi-info software. Of 24 patients only 19 got complete information. It was found a 22% of patients with positives adenopatias to level of histological study with a ganglionic compromise of 32% in general form, a 36% in the stages IB1 and a 25% in stages IB2. Of all the patients that presented ganglionic metastasis illness, did not get to show with the computerized axial tomography and it is concluded that TAC is a bad method for detection of the microscopic metastasis illness, or at least to 2 cm. None of the patients in stages IB1 presented relapse data in the observed period, founding a 100% of survival to 24 months. The patients in stages IB2 presented relapses, with a 75% of survival

    To assess the predictive value of diffusion weighted imaging (DWI) for survival in women treated for advanced cancer of the cervix with concurrent chemo-radiotherapy. Twenty women treated for advanced cancer of the cervix were recruited and followed up for a median of 26 (range <1 to 43) months. They each had DWI performed before treatment, 2 weeks after beginning therapy (midtreatment) and at the end of treatment. Apparent diffusion coefficient (ADC) values were calculated from regions of interest (ROI). All participants were reviewed for follow-up data. ADC values were compared with mortality status (Mann-Whitney test). Time to progression and overall survival were assessed (Kaplan-Meier survival graphs). There were 14 survivors. The median midtreatment ADC was statistically significantly higher in those alive compared to the non-survivors, 1.55 and 1.36 (x 10{sup -3}/mm{sup 2}/s), respectively, P = 0.02. The median change in ADC 14 days after treatment commencement was significantly higher in the alive group compared to non-survivors, 0.28 and 0.14 (x 10{sup -3}/mm{sup 2}/s), respectively, P = 0.02. There was no evidence of a difference between survivors and non-survivors for pretreatment baseline or post-therapy ADC values. Functional DWI early in the treatment of advanced cancer of the cervix may provide useful information in predicting survival. (orig.)

    Full Text Available Background Cancer, the disease of intricateness, has remained beyond our complete perception so far. Network systems biology (termed NSB is one of the most recent approaches to understand the unsolved problems of cancer development. From this perspective, differential protein networks (PINs have been developed based on the expression and interaction data of brain, cervix, lung, ovary and prostate for normal and cancer conditions. Methods Differential expression database GeneHub-GEPIS and interaction database STRING were applied for primary data retrieval. Cytoscape platform and related plugins named network analyzer; MCODE and ModuLand were used for visualization of complex networks and subsequent analysis. Results Significant differences were observedamong different common network parameters between normal and cancer states. Moreover, molecular complex numbers and overlapping modularization found to be varying significantly between normal and cancerous tissues. The number of the ranked molecular complex and the nodes involved in the overlapping modules were meaningfully higher in cancer condition.We identified79 commonly up regulated and 6 down regulated proteins in all five tissues. Number of nodes, edges; multi edge node pair, and average number of neighbor are found with significant fluctuations in case of cervix and ovarian tissues.Cluster analysis showed that the association of Myc and Cdk4 proteins is very close with other proteins within the network.Cervix and ovarian tissue showed higher increment of the molecular complex number and overlapping module network during cancer in comparison to normal state. Conclusions The differential molecular signatures identified from the work can be studied further to understand the cancer signaling process, and potential therapeutic and detection approach.

  14. High-dose-rate brachytherapy in the treatment of uterine cervix cancer. Analysis of dose effectiveness and late complications

    International Nuclear Information System (INIS)

    Purpose: This retrospective analysis aims to report results of patients with cervix cancer treated by external beam radiotherapy (EBR) and high-dose-rate (HDR) brachytherapy. Methods and Materials: From September 1992 to December 1996, 138 patients with FIGO Stages II and III and mean age of 56 years were treated. Median EBR to the whole pelvis was 45 Gy in 25 fractions. Parametrial boost was performed in 93% of patients, with a median dose of 14.4 Gy. Brachytherapy with HDR was performed during EBR or following its completion with a dose of 24 Gy in four weekly fractions of 6 Gy to point A. Median overall treatment time was of 60 days. Patient age, tumor stage, and overall treatment time were variables analyzed for survival and local control. Cumulative biologic effective dose (BED) at rectal and bladder reference points were correlated with late complications in these organs and dose of EBR at parametrium was correlated with small bowel complications. Results: Median follow-up time was 38 months. Overall survival, disease-free survival, and local control at 5 years was 53.7%, 52.7%, and 62%, respectively. By multivariate and univariate analysis, overall treatment time up to 50 days was the only statistically significant adverse variable for overall survival (p=0.003) and actuarial local control (p=0.008). The 5-year actuarial incidence of rectal, bladder, and small bowel late complications was 16%, 11%, and 14%, respectively. Patients treated with cumulative BED at rectum points above 110 Gy3 and at bladder point above 125 Gy3 had a higher but not statistically significant 5-year actuarial rate of complications at these organs (18% vs. 12%, p=0.49 and 17% vs. 9%, p=0.20, respectively). Patients who received parametrial doses larger than 59 Gy had a higher 5-year actuarial rate of complications in the small bowel; however, this was not statistically significant (19% vs. 10%, p=0.260). Conclusion: This series suggests that 45 Gy to the whole pelvis combined with

  15. The influence of bone density on the radiotherapy of cervix cancer

    International Nuclear Information System (INIS)

    Until the 1970s the irradiated region of a patient undergoing external beam radiotherapy was considered a homogeneous volume and a regular surface, with physical characteristics similar to water. With the improvement of medical imaging equipment, it has become possible to conduct planning in radiotherapy treatment that considers the heterogeneities and irregularities of a patient's anatomy. Consequently, such technological resources have brought greater accuracy to radiotherapy. In this study, we determined the variation in the average amount of absorbed dose on the target volume and at the point of prescription treatment by comparing the doses which were calculated in a planning system considering the patient both as a homogeneous, and as a heterogeneous medium. The results showed that when we take into account the volume of the upper vagina and cervix, and consider the pelvis as a heterogeneous medium, the calculated dose was under-estimated at some points in the studied volume with respect to the dose when this region was considered homogeneous.

    Full Text Available Orthogonal film-based treatment planning is the most commonly adopted standard practice of treatment planning for cancer of the uterine cervix using high dose rate brachytherapy (HDR. This study aims at examining the variation in rectal and bladder doses when the same set of orthogonal films was given to different observers. Five physicists were given 35 pairs of orthogonal films obtained from patients who had undergone HDR brachytherapy. They were given the same instructions and asked to plan the case assuming the tumor was centrally placed, using the treatment-planning system, PLATO BPS V13.2. A statistically significant difference was observed in the average rectal (F = 3.407, P = 0.01 and bladder (F = 3.284, P = 0.013 doses and the volumes enclosed by the 100% isodose curve ( P < 0.01 obtained by each observer. These variations may be attributed to the differences in the reconstruction of applicators, the selection of source positions in ovoids and the intrauterine (IU tube, and the differences in the selection of points especially for the rectum, from lateral radiographs. These variations in planning seen within a department can be avoided if a particular source pattern is followed in the intrauterine tube, unless a specific situation demands a change. Variations in the selection of rectal points can be ruled out if the posterior vaginal surface is clearly seen.

  1. Prognostic factors in patients with cervix cancer treated by radiation therapy: results of a multiple regression analysis

    International Nuclear Information System (INIS)

    A retrospective analysis of 965 patients with invasive cervix cancer treated by radiation therapy between 1976 and 1981 was performed in order to evaluate prognostic factors for disease-free survival (DFS) and pelvic control. FIGO stage was the most powerful prognostic factor followed by radiation dose and treatment duration (P values = 0.0001). If the analysis was limited to patients treated with radical doses of 75 Gy or more, dose was no longer significant. Young age at diagnosis, non-squamous histology and transfusion during treatment were also adverse prognostic factors for survival and control. Para-aortic nodal involvement on lymphogram was associated with a reduction in DFS (P = 0.0027), whereas pelvic lymph node involvement alone was not. In patients with Stage I and IIA disease, tumour size was the most powerful prognostic factor for survival (P = 0.0001) and the extent of pelvic sidewall involvement was significant in patients with Stage III tumours (P = 0.007). Histological grade appeared to be a predictive factor but was only recorded in 712 patients. These features should be considered in the staging of patients and in the design of clinical trials

  3. Simple DVH parameter addition as compared to deformable registration for bladder dose accumulation in cervix cancer brachytherapy

    International Nuclear Information System (INIS)

    Background and purpose: Variations in organ position, shape, and volume cause uncertainties in dose assessment for brachytherapy (BT) in cervix cancer. The purpose of this study was to evaluate uncertainties associated with bladder dose accumulation based on DVH parameter addition (previously called “the worst case assumption”) in fractionated BT. Materials and methods: Forty-seven patients treated for locally advanced cervical cancer were included. All patients received EBRT combined with two individually planned 3D image-guided adaptive BT fractions. D2cm3 and D0.1cm3were estimated by DVH parameter addition and compared to dose accumulations based on an in-house developed biomechanical deformable image registration (DIR) algorithm. Results: DIR-based DVH analysis was possible in 42/47 patients. DVH parameter addition resulted in mean dose deviations relative to DIR of 0.4 ± 0.3 Gyαβ3 (1.5 ± 1.8%) and 1.9 ± 1.6 Gyαβ3 (5.2 ± 4.2%) for D2cm3 and D0.1cm3, respectively. Dose deviations greater than 5% occurred in 2% and 38% of the patients for D2cm3 and D0.1cm3, respectively. Visual inspection of the dose distributions showed that hotspots were located in the same region of the bladder during both BT fractions for the majority of patients. Conclusion: DVH parameter addition provides a good estimate for D2cm3, whereas D0.1cm3 is less robust to this approximation

    METHODS: We assessed second cancer risk among 85,109 cervical SCC and 10,280 AC survivors reported to population-based cancer registries in Denmark, Finland, Norway, Sweden, and the United States. Risks compared to the general population were assessed using standardized incidence ratios (SIR). RESULTS......: Overall cancer risk was significantly increased among both cervical SCC survivors (n = 10,559 second cancers; SIR, 1.31; 95% CI, 1.29 to 1.34) and AC survivors (n = 920 second cancers; SIR, 1.29; 95% CI, 1.22 to 1.38). Risks of HPV-related and radiation-related cancers were increased to a similar extent...... among cervical SCC and AC survivors. Although significantly increased in both groups when compared with the general population, risk of smoking-related cancers was significantly higher among cervical SCC than AC survivors (P = .015; SIR for cervical SCC = 2.07 v AC = 1.78).

  5. Carcinoma of the cervix

    International Nuclear Information System (INIS)

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

    Full Text Available Cervical cancer is the leading cancer-related cause of death among women in Nigeria. An estimated 70,700 new cases occur each year, representing one quarter of all female cancers in sub Saharan Africa. The magnitude of the problem has been under recognised and under prioritised compared with the competing health priorities of infectious diseases such as HIV/ AIDS, tuberculosis and malaria. Studies in the United States and Nigeria have indicated that the disease has the highest incidence among the lowest socio-economic groups especially residing in rural areas. The peak age for the disease has been shown to be within 35-45 years age group. Knowledge of the risk factors of the disease is deemed important in its early detection and prevention. The objective of this study was to assess the knowledge, attitude and practice of rural women with cancer of the cervix. A cross sectional descriptive study was conducted among 1600 rural women aged 15-55 years (randomly selected from 28 villages who were interviewed using a structured questionnaire between April and June, 2010. The majority (82.2% were married before the age of 20 years and 19.3% before 15 years, 40% in polygamous union, 22.6% have had 2 or more sexual partners, 71.3% were primi and grand multiparous, 7.5% have had previous treatment for STIs and 10.1% were on various types of contraceptive. 454 (28.4% have heard of Ca cervix, 358 (22.4% knew the location of the cervix. 2.3% had Pap smear test of which 72.6% were within 2 years. The majority (89.9% will avail themselves for screening.

Setting: Rural: Village East Gobindopur is Singur block in Hooghly district of West Bengal. Study population : All the married women of reproductive age group (103 of the village were included in the study. Results: More than two â€" third (72.8% of the study population belonged to the vulnerable age group (25-45 years for this disease while 59.3% were married before they attained 18 years of age. Again 50% (approx of the married women gave birth to their first child before they were 18 years of age. One â€" third of the study population had parity higher than three. Two â€" third of the women studied were using one or more methods of family planning and one â€" third of the same population were permanently sterilized, 20% were using oral contraceptive pills and only 7.7% were using barrier methods of contraception. Only 31% of the women had satisfactory genital hygiene practice and 36.9% had symptoms of reproductive tract infection. Conclusion: There was a high prevalence of some important risk factors associated with cancer cervix like age, age of marriage, age of first child birth, parity ,family planning practices, genital hygiene and reproductive tract infections in the study population. Therefore screening and early detection efforts can be directed specifically to the group at risk.

  8. Prognostic value of response to external radiation in stage IIIB cancer cervix in predicting clinical outcomes: A retrospective analysis of 556 patients from India

    International Nuclear Information System (INIS)

    Background and purpose: To evaluate the prognostic significance of response to external beam radiation (EBRT) in predicting the clinical outcomes in stage IIIB cancer cervix and to find out factors affecting response to EBRT. Patients and methods: This retrospective study included 556 patients of cancer cervix stage IIIB treated between 1996 and 2001 with EBRT (46 Gy/23fx/4.5 weeks) followed by intracavitary radiotherapy (ICRT). At the end of EBRT, response to EBRT was grouped as 'no gross residual tumor'(NRT) or 'gross residual tumor'(GRT). Results: Follow up ranged from 2 to 93 months with a median of 36 months. Median dose to point A was 81 Gy. At the end of EBRT, 393 patients (70.7%) attained NRT response. NRT responders had significantly better 5 year pelvic control, disease free survival (DFS) and overall survival (OS) than those who had a GRT response (75.6 vs. 54.6%; 60.6 vs. 31.9% and 62.6 vs. 33.7%, respectively; all P values <0.0001). Apart from response to EBRT, overall treatment time also has emerged as an independent factor to affect all clinical outcomes in multivariate analysis but age had significant impact on pelvic control only. Age was the only factor, which significantly influenced the response to EBRT in univariate as well as multivariate analysis (P=<0.001, OR=1.973, 95% C.I. 1.357-2.868). Patients with age more than 50 years had more NRT response (77%) than patients with age less than 50 years (63.8%). Conclusions: Patients who attain NRT response to EBRT will have an impressive long term pelvic control, DFS and OS in stage IIIB cancer cervix. Older patients (≥50 years) attain significantly higher NRT rates than younger patients

    The purpose of this study was to investigate the effect of fermented mushroom of Cordyceps sinensis (CS), rich in selenium (Se-CS), on uterine cervical cancer in mice. The methylcholanthrene- (MCA-) induced tumor model was used in this paper. After the mice were administered Se-CS, the animals showed 40% tumor incidence (P < 0.05). Se-CS also enhanced the immune functions. Se-CS treatment showed significant (P < 0.05-0.01) restoration in the level of glutathione content, lipid peroxidation, glutathione peroxidase activity, glutathione reductase activity, catalase activity, Na(+)/K(+)-ATPase activity, and glutathione S transferase activity. This finding suggested that the concomitant use of Se and CS could be a potential therapeutic approach to improve the efficacy of therapy for uterine cervical cancer. PMID:24971145

    Full Text Available Establishing how a series of potentially important genes might relate to each other is relevant to understand the origin and evolution of illnesses, such as cancer. High‑throughput biological experiments have played a critical role in providing information in this regard. A special challenge, however, is that of trying to conciliate information from separate microarray experiments to build a potential genetic signaling path. This work proposes a two-step analysis pipeline, based on optimization, to approach meta-analysis aiming to build a proxy for a genetic signaling path.

    Full Text Available Objective: Analysis was done to assess the implications of total radiation treatment duration towards locally advanced cervical cancer. Methods: A comparative study was conducted in CNCI, Kolkata. A total of 38 patients were studied with interdigited brachyttherapy during the course of conventional teleradiotherapy and they were compared to a total of 39 patients with conventional sequential teletherapy and brachytherapy. Results: In the experimental arm all the patients had complete response to treatment whereas, 24 patients (85.7% in the conventional arm had complete response [ P = 0.08]. At the last follow up 28 patients (73.68% in the study arm and 17 patients (43.58% in the control arm were free of disease. The failure rate in the conventional control arm was significantly higher [ P = 0.035]. Test of proportion derived from data also showed that the proportion of patients with no evidence of disease at the time of last follow-up was significantly higher in the study arm compared to the control arm [ P < 0.05] and the proportion of patients with persistent disease was significantly less in the stuwdy arm compared to the control arm [ P < 0.05]. The probability of disease-free survival in percentage according to the curve at the time of median follow-up was approximately 70% for study arm and 60% for control arm [log-rank test, P = 0.2463]. Conclusion: we should hence minimize treatment time and avoid any planned or unplanned interruptions or delays by timely integration of external beam and intra-cavitary irradiation that may yield a better local control in locally advanced cervical cancer

  16. Pelvic exenteration for cervix cancer: would additional intraoperative interstitial brachytherapy improve survival?

    International Nuclear Information System (INIS)

    Objective: Improved local control with the addition of brachytherapy to pelvic exenteration for recurrent cervical cancer has been reported to improve survival. We examined the sites of recurrence after pelvic exenteration to determine if these patients might have been salvaged by the improved local control promised by interstitial brachytherapy. We sought to identify risk factors available intraoperatively or perioperatively which might predict decreased local control. Methods: A retrospective review of 26 patients with recurrent cervical cancer who underwent total pelvic exenteration since 1988 at our institution was performed. Results: Overall, the mean follow-up was 29.5 months (range 6.1-81.6). Of the 26 patients, 14 had no evidence of disease (NED), 1 was alive with disease (AWD), 9 were dead of disease (DOD), and 2 died of unrelated causes (DOC). Seven of 26 patients (27%) had margins ≤ 5 mm, of whom 2 were NED, 4 DOD, and 1 AWD. Seven of 26 (27%) patients had lymphovascular involvement (LVI) or perineural invasion (PNI) with clear margins. Three of the seven with LVI or PNI and clear margins were NED, and four DOD. Of the 10 failures, 9 (90%) had close margins, PNI, or LVI. Conclusion: Our data reveal that 9 of 14 (64%) patients with close margins, LVI, or PNI were DOD or AWD, and 6 of 9 of those patients suffered local regional failure alone. Brachytherapy has the potential to cure 6 of 14 (43%) patients with these risk factors. Further study of brachytherapy at the time of pelvic extenteration is warranted

    A new experimental system was designed to study human uterine activities based on the extra-corporeal perfusion of isolated human uteri. Electromechanical activities in the uterine wall were recorded using bipolar silver-silver electrodes, endoluminal pressure catheters and a dedicated acquisition, storage and analytical system. The electrical signals recorded were isolated spikes and rhythmic activities; the last being primarily associated with organized mechanical events. Perfusion media containing 17 beta-oestradiol alone or with progesterone were used for those uteri obtained during proliferative (n = 5) or secretory (n = 5) phases of the menstrual cycle, respectively. Progesterone caused a reduction of frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity, and decreased the endoluminal pressure at both detection sites (P < 0.01). 17 beta-Oestradiol increased both frequency (P < 0.001) and duration (P < 0.001) of the rhythmic electrical activity as well as the endoluminal pressure at two different detection sites (3 and 5 cm from the fundus) (P < 0.05). Significant differences between the fundus and cervix sites in the uterine wall were detected. In conclusion, uterine perfusion would be useful to examine the effects of uterotonic and tocolytic drugs before administration to humans, at no risk to the patients. Oestrogens increase and progesterone decreases both electrical and mechanical uterine activities. PMID:8300807

    Full Text Available OBJECTIVE: To assess the validity of Colposcopy using Modified Reid's Index as a screening tool in cervical cancer in women with abnormal cervix on naked eye examination . METHODS: This observational study was carried out in Government medical college, Aurangabad from June 2011 to May 2013 . Total 392 women with abnormal cervix on naked eye examination of underwent colposcopy and diagnosis was made on the basis of Modified R eid’s Index. Colposcope directed biopsies were obtained from the abnormal areas. In women with normal colposcopic findings four quadrant biopsies from squamo - columnar junction were taken .Eight women were excluded from analysis owing to unsatisfactory colp oscopy. Results of colposcopy were validated by calculating sensitivity, specificity, positive predictive value, negative predictive value in diagnosing histopathologically confirmed lesions which served as gold standard. RESULTS: Overall sensitivity of colposcopy in all grades of lesions is around 90% or more, touching 100% in high order of histological lesions.Overall specificity is also high.It does have an excellent negative predictive value but comparatively lower positive predictive value especially in high order lesions with fair degree of accuracy in all grades of lesions in the hands of an experienced operator. CONCLUSION: Colposcopy using Modified Reid’s Index with high sensitivity and specificity is a good screening tool for cervical cancer

    For online adaptive radiotherapy of cervical cancer, fast and accurate image segmentation is required to facilitate daily treatment adaptation. Our aim was twofold: (1) to test and compare three intra-patient automated segmentation methods for the cervix-uterus structure in CT-images and (2) to improve the segmentation accuracy by including prior knowledge on the daily bladder volume or on the daily coordinates of implanted fiducial markers. The tested methods were: shape deformation (SD) and atlas-based segmentation (ABAS) using two non-rigid registration methods: demons and a hierarchical algorithm. Tests on 102 CT-scans of 13 patients demonstrated that the segmentation accuracy significantly increased by including the bladder volume predicted with a simple 1D model based on a manually defined bladder top. Moreover, manually identified implanted fiducial markers significantly improved the accuracy of the SD method. For patients with large cervix-uterus volume regression, the use of CT-data acquired toward the end of the treatment was required to improve segmentation accuracy. Including prior knowledge, the segmentation results of SD (Dice similarity coefficient 85 ± 6%, error margin 2.2 ± 2.3 mm, average time around 1 min) and of ABAS using hierarchical non-rigid registration (Dice 82 ± 10%, error margin 3.1 ± 2.3 mm, average time around 30 s) support their use for image guided online adaptive radiotherapy of cervical cancer.

    Full Text Available Background: Cisplatin is widely used as radio sensitizer in head and neck cancer (HNC and carcinoma cervix (CaCx. This study aims to see comparative nephrotoxicity of cisplatin in HNC and in CaCx without obstructive uropathy treated by concurrent chemoradiotherapy (CCRT. Materials and Methods: Fifty patients of HNC and 50 patients of CaCx stage II/III without obstructive uropathy were included in this study. Cisplatin 50 mg intravenous weekly was given before EBRT with adequate hydration and premedication in both groups. Before chemotherapy; blood urea, serum creatinine, and glomerular filtration rate (GFR were measured. GFR was measured using 99m Tc diethylene triamine pentacaetic acid (DTPA renogram study. Results: At the end of 4 th week, blood urea level 41-45 mg% was in 40 and 4% in HNC and CaCx, respectively (P = 0.018. At the end of 3 rd and 4 th week, blood urea level >45 mg% was 10 and 6% in HNC cases, respectively. At the end of 4 th week, serum creatinine level 1.1-1.5 mg% was 50 and 8% in HNC and CaCx, respectively (P = 0.047. Serum creatinine level >1.5 mg% was 6, 8, and 22% in HNC at the end of 2 nd , 3 rd , and 4 th week, respectively. GFR <80 ml/min at the end of 4 th week was 14% in HNC and only 2% in CaCx. GFR <100ml/min was significant at the end of 4 th week (P = 0.04. Univariate analysis showed significant relation between reduced oral fluid intake and reduced GFR (P < 0.001. Conclusion: In HNC, during concurrent chemoradiation, as the 3 rd -4 th week is reached, oral mucosal reactions increase and affect oral intake which further add to the cisplatin-induced nephrotoxicity. In CaCx without obstructive uropathy, renal function impairment is less severe as oral intake of water and liquid is not much impaired.

  1. Biological dose estimation of partial body exposures in cervix cancer patients

    International Nuclear Information System (INIS)

    fraction. Cells containing aberrations will have been in the irradiated part of the body. Normal undamaged cells will comprise two subpopulations; those from the unexposed fraction and irradiated cells representing the first term (e-γ) of the Poisson series. From the degree of the deviation from Poisson, the fraction of irradiated lymphocytes of the body and its mean dose can be obtained. The alternative Qdr method considers the yield of dicentrics and rings only from those cells that contain unstable aberrations and assumes that these cells were irradiated in situ. The Qdr value represents the expected frequency of dicentrics and rings among first division damaged cells (containing dicentrics, rings and excess acentric fragments). It is dose dependent, but independent of dose homogeneity and of a dilution of damaged cells by undamaged cells. Qdr assumes that the excess acentric fragments follow the Poisson distribution, but this is not borne out by data from in vitro experiments. It also assumes that cells containing excess acentric fragments will have been in the irradiated fraction of the body. However, their induction is not radiation specific, showing a variable spontaneous frequency, As these limitations are thought to be important, they were avoided by considering the yield of dicentrics + rings in those damaged cells which contain just dicentrics + rings (Qdr reduced equations). This simplified equation produces a dose estimate identical to that obtained by Dolphin method. Therefore, we apply Qdr reduced equation for data analysis. After inhomogeneous exposures, information on the absorbed dose and its distribution in the body is of great importance for an early assessment of irradiation consequences in the exposed individuals. As cancer patients undergoing partial-body fractionated radiotherapy may provide a model for in vivo irradiation, the objective of this work has been to assess the possibilities and limitations of Qdr method to determine reliable dose

    Interstitial and endocavity ultrasound devices have been developed specifically for applying hyperthermia within temporary HDR brachytherapy implants during radiation therapy. Catheter-based ultrasound applicators are capable of 3D spatial control of heating in both angle and length of the devices, with enhanced radial penetration of heating compared to other hyperthermia technologies. A pilot study of the combination of catheter based ultrasound with HDR brachytherapy for locally advanced prostate and cervical cancer has been initiated, and preliminary results of the performance and heating distributions are reported herein. The treatment delivery platform consists of a 32 channel RF amplifier and a 48 channel thermocouple monitoring system. Controlling software can monitor and regulate frequency and power to each transducer section as required during the procedure. Interstitial applicators consist of multiple transducer sections of 2-4 cm length×180 deg and 3-4 cm×360 deg. heating patterns to be inserted in specific placed 13g implant catheters. The endocavity device, designed to be inserted within a 6 mm OD plastic tandem catheter within the cervix, consists of 2-3 transducers x dual 180 or 360 deg sectors. 3D temperature based treatment planning and optimization is dovetailed to the HDR optimization based planning to best configure and position the applicators within the catheters, and to determine optimal base power levels to each transducer section. To date we have treated eight cervix implants and four prostate implants. 100% of treatments achieved a goal of >60 min duration, with therapeutic temperatures achieved in all cases. Thermal dosimetry within the hyperthermia target volume (HTV) and clinical target volume (CTV) are reported. Catheter-based ultrasound hyperthermia with HDR appears feasible with therapeutic temperature coverage of the target volume within the prostate or cervix while sparing surrounding more sensitive regions.

    Full Text Available The development of acute myeloid leukaemia after low-dose radioiodine therapy and its presentation as a myeloid sarcoma of the uterine cervix are both rare events. We report a case of acute myeloid leukaemia revealed by a myeloid sarcoma of the uterine cervix in a 48-year-old woman, 17 months after receiving a total dose of 100 mCi 131I for papillary thyroid cancer. A strict hematological follow-up of patients treated with any dose of 131I is recommended to accurately detect any hematological complications which might have been underestimated. Unusual presentations, such as chloroma of the uterine cervix, may reveal myeloid malignancy and should be kept in mind.

  5. A correlation between residual DNA double-strand breaks and clonogenic measurements of radiosensitivity in fibroblasts from preradiotherapy cervix cancer patients

    International Nuclear Information System (INIS)

    Purpose: To study the relationship between residual DNA damage and clonogenic measurements of radiosensitivity in fibroblasts from pretreatment cervix cancer patients. Methods and Materials: Early passage vaginal fibroblasts from nine preradiotherapy cervix cancer patients and two radiosensitive skin fibroblast cell strains were studied. Cell survival was measured by clonogenic assay following both high and low dose rate irradiation. Residual DNA damage was measured using pulsed-field gel electrophoresis (PFGE) after irradiating radiolabeled, plateau-phase cells at 37 deg. C and allowing 24 h for repair. DNA damage was expressed both in terms of the residual damage slope (fitted to data from 60 to 150 Gy) and the fraction of activity released (FAR) following 150 Gy. Results: The surviving fraction at 2 Gy (SF2) values after high dose rate irradiation for the vaginal fibroblasts ranged from 0.15 to 0.32 (a 2.2-fold difference). When the two radiosensitive cell strains were included, residual damage, expressed as the residual damage slope, correlated with α (r = 0.82, p = 0.002), D bar (r = -0.91, p 2 (p = -0.79, p = 0.004), and when the vaginal fibroblasts alone were studied, the residual damage slope again correlated with clonogenic survival, although less strongly [α (r 0.66, p = 0.053), D bar (r = -0.83, p = 0.006), and SF2 (r = -0.63, p 0.07)]. Within the group of vaginal fibroblasts there was a 4.0-fold difference in residual DNA damage slope. When residual damage was expressed as FAR at 150Gy, then for all cell strains the correlations were α: r 0.78, p 0.004, D bar: r = -0.86, p = 0.001, and SF2: r = -0.78, p = 0.004, and for the vaginal fibroblast strains alone the correlations were α: r = 0.60, p = 0.088, D bar: r = -0.75, p = 0.02, and SF2: r = 0.62, p = 0.077. Conclusion: This study confirms previous findings that residual DNA damage correlates with clonogenic survival in fibroblasts. In addition, it demonstrates a correlation for fibroblasts from

  6. Micronucleus test in cytokinesis-blocked lymphocytes of cervix cancer patients as a predictive assay of individual radiosensitivity

    International Nuclear Information System (INIS)

    The ability to control a tumor by radiation therapy is limited by the tolerance of normal tissues within the treatment field, particularly by the occurrence of severe late normal tissue reactions (NTR), developed month to years after treatment. Patients receiving identical radiation treatments have different impacts on normal tissues, varying from undetectable to sever. Cellular and molecular mechanisms of these reactions are not yet understood. It has been suggested that the extent of late NTR may depend on the individual cellular radiosensitivity, associated with defects in DNA repair capacity. There is some evidence in favor of the hypothesis that in vitro radiosensitivity tests, in normal or neoplastic cells, are predictive of clinical expression of late normal tissue complications after radiotherapy. Intrinsic radiosensitivity testing is considered more feasible and promising in normal than tumor tissues because normal cell populations are less heterogeneous than tumor cell populations, and clinical studies on radiosensitivity are easier to implement. Peripheral blood lymphocytes are considered the cells of choice because they are easy to obtain, with minimal trauma to donors, and to use for in vitro tests, giving quick results. The cytokinesis-blocked micronucleus assay is an established cytogenetic technique to evaluate intrinsic cell radiosensitivity in tumor cells and lymphocytes. The objective of our study was to assess, prospectively, the individual cytogenetic response to radiotherapy applying the cytokinesis blocked micronucleus (MN) assay to peripheral blood lymphocytes from cervix cancer patients undergoing radiation therapy as part of their treatment, in comparison with the observed clinical response. Blood samples were collected just before treatment, mid-way during treatment and/or on completion of treatment. Cytogenetic data were analyzed using a mathematical model to evaluate the attenuation of the cytogenetic effect as a function of the time

  7. Detection of organ movement in cervix cancer patients using a fluoroscopic electronic portal imaging device and radiopaque markers

    International Nuclear Information System (INIS)

    Purpose: To investigate the use of a fluoroscopic electronic portal imaging device (EPID) and radiopaque markers to detect internal cervix movement. Methods and Materials: For 10 patients with radiopaque markers clamped to the cervix, electronic portal images were made during external beam irradiation. Bony structures and markers in the portal images were registered with the same structures in the corresponding digitally reconstructed radiographs of the planning computed tomogram. Results: The visibility of the markers in the portal images was good, but their fixation should be improved. Generally, the correlation between bony structure displacements and marker movement was poor, the latter being substantially larger. The standard deviations describing the systematic and random bony anatomy displacements were 1.2 and 2.6 mm, 1.7 and 2.9 mm, and 1.6 and 2.7 mm in the lateral, cranial-caudal, and dorsal-ventral directions, respectively. For the marker movement those values were 3.4 and 3.4 mm, 4.3 and 5.2 mm, 3.2 and 5.2 mm, respectively. Estimated clinical target volume to planning target volume (CTV-PTV) planning margins (∼11 mm) based on the observed overall marker displacements (bony anatomy + internal cervix movement) are only marginally larger than the margins required to account for internal marker movement alone. Conclusions: With our current patient setup techniques and methods of setup verification and correction, the required CTV-PTV margins are almost fully determined by internal organ motion. Setup verification and correction using radiopaque markers might allow decreasing those margins, but technical improvements are needed

  8. Design and construction of a holder to the safety handling of Cs-137 to be used in cervix cancer treatments using intracavitary brachytherapy by afterloading

    International Nuclear Information System (INIS)

    In venezuelan public hospitals where cervix cancer treatments are performed by means of Cs-137 manual afterloading systems, the handling of the sources is done with two type of holders, metallic and plastic, the plastic holders are pieces of induced serious radio-sanitary problem such as loser of the Cs-137 source and radioactive contamination in the treatment area, this has caused the interruption of the treatments in many hospitals. This interruption had a high social cost because of the thousands women waiting for intracavitary therapy. To start again with the treatments, the metallic holders were required but there were not enough funds in the budget, because of this problem in a short time IVIS'S health physics drew and made a low price source holder.

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

  12. Descriptive study of breast and cervix cancer, in patients treated with linear accelerator, at the Centro Medico de Radioterapia Irazu, between 2000 and 2001, and proposed a database

    International Nuclear Information System (INIS)

    A descriptive study of breast and cervix cancer was performed in patients who have received treatment linear accelerator, during the period 2000 - 2001 in the Centro Medico de Radioterapia Irazu. The survival of the patients was assessed to five years (2006). One proposal called database is the product of analysis performed and consistent with the objectives set. The idea to develop the database of these features in the medical center, arises because the Centre was at that time with the only linear accelerator in the country and also all the necessary information of patients was easily accessible. A population of 438 records, with a common pathology was analyzed under the following variables: type of cancer, identification of anatomic region, province, age, sex, type of radiation, number of sessions, referral hospital, physician, physician referral. This work is relevant, because breast and cervical cancers have been a major cause of mortality, ranked among the five most common malignancies in women. From there to have adequate information systems, has led policy makers and health professionals to have a better outlook for their level of management. (author)

    Of the 300 clinical files of pregnant women, 22 were associated with cancer plus pregnancy in 5 years. Of them 7 were excluded in the work. 15 patients with CaCu and pregnancy were studied in the Gineco-Obstetric Hospital No. 3 C.M. La Raza of the IMSS México City in a period since 1st of January 1988 to 31st December of 1992. Early menarchia and sexual life, take an important roll in the mexican women as predisponent factors, multideliver and tobacco too. The colposcopy with manage cervix biopsy is the election method of diagnosis, with 99.5% of confiability. In the 15 patients, the estirpe was epidermoid cancer in all of them. The diagnosis of pregnancy age made in the first and third trimester of gestation. Only in 3 patients (20%) were founded visible lesion, this rename the necessity of make detection of CaCu during the pregnancy, because we will can found the cases in preinvader stages or early invader, that cure highly, like the cases seen in this work. Stages preinvader and early invaders during the pregnancy are highly curatives. We concluded that they have worst prognosis of survival, aggressivity and early relapse in patients with pregnancy stage by stage. The last because in the Historical Literature review about this topic, there was statistical relevance about pregnancy in the women with CaCu, using our work for reference. CaCu does change his prognosis associated with the pregnancy. PMID:10692806

    Purpose: To compare the dosimetric difference of the target volume and organs at risk(OARs) between conventional intensity-modulated radiotherapy(C-IMRT) and knowledge-based radiation therapy (KBRT) plans for cervix cancer. Methods: 39 patients with cervical cancer after surgery were randomly selected, 20 patient plans were used to create the model, the other 19 cases used for comparative evaluation. All plans were designed in Eclipse system. The prescription dose was 30.6Gy, 17 fractions, OARs dose satisfied to the clinical requirement. A paired t test was used to evaluate the differences of dose-volume histograms (DVH). Results: Comparaed to C-IMRT plan, the KBRT plan target can achieve the similar target dose coverage, D98,D95,D2,HI and CI had no difference (P≥0.05). The dose of rectum, bladder and femoral heads had no significant differences(P≥0.05). The time was used to design treatment plan was significant reduced. Conclusion: This study shows that postoperative radiotherapy of cervical KBRT plans can achieve the similar target and OARs dose, but the shorter designing time.

  15. An experimental study on cervix cancer with combination of HSV-TK/GCV suicide gene therapy system and 60Co radiotherapy

    International Nuclear Information System (INIS)

    To evaluate the killing effect of HSV-TK/GCV suicide gene therapy system combined with 60Co radiotherapy on human cervical cancer Hela cell line in vitro and in vivo, and to explore the radiosensitization by HSV-TK/GCV system. HSV-TK/GCV suicide gene therapy system and 60Co radiotherapy were used separately or in combination on human cervical cancer Hela cell line in vitro and in vivo to compare their effects. Colony formation test and the rate of radiosensitization effect (E/O) were employed to observed the radiosensitization by HSV-TK/GCV system. HSV-TK/GCV suicide gene therapy system had strong therapeutic effects on Hela cells in vitro and in vivo (the inhibition rates were 45.8% and 39.5%, respectively), moreover, the combined administration of gene therapy and radiotherapy had stronger therapeutic effects in vitro and in vivo (the inhibition rate was 87.5% in vitro, and the inhibition rate was 87.9% in vivo) (P < 0.01). The inhibition rate by radiotherapy alone was 42.4% in vitro and 35.8% in vivo. The sensitivity of combined therapy to radiotherapy increased more than that of therapy alone, the ability of colony formation decreased (P < 0.01). The rate of radiosensitivity effect (E/O) was 3.17(> 1.4), indicating HSV-TK/GCV system could exert a sensitizing effect on 60Co radiotherapy of the transplanted human cervical cancer cell in nude mice. HSV-TK/GCV system had radiosensitization. Gene therapy combined with radiotherapy may be a good supplementary method for cervix cancer synthetic treatment

  16. Early and Late Bowel Complication Following Irradiation of Cancer of the Uterine Cervix-Whole Pelvis External Irradiation end High-Dose-Rate Interactively Irradiation

    International Nuclear Information System (INIS)

    Cervix cancer is the most common female cancer in Korea. In spite of their relatively local invasive tendency, still 44% of patient will develop recurrent cancer This result suggests that more aggressive local treatment may increase the cure rate but increased complication risk also cannot be avoidable. Various institutions proposed different treatment regimen, but recommended dose were about 4500 cGy for whole pelvis and 8000 cGy at point A, even though they agreed that those doses may not be satisfactory for control of bulky disease. 96 cases of invasive cervical cancer, treated with postoperative or primary radiation therapy were analyzed to determine the complication rate and prognostic factor in our treatment regimen which is 500-1000 cGy higher than other institution. Mean follow up duration was 21 months. Symptomatic patients including mild but persistent abdominal discomfort was 46%, but only 1 patient (1%) had operative treatment because of incomplete obstruction of small bowel. Most symptoms appeared within 12 months and most common complaints were frequent bowel movement. Barium enema and sigmoidoscopy were performed for persistent symptomatic patients. Only one patient had abnormal finding in barium enema which showed inefficiency of this method for detecting bowel complication. Patient age, total tumor dose, total TDF, rectal dose were not significant risk factors for complication, but boost dose, previous history of operation had some relationship with complication risk. Even though dose of point A and rectum is 500-1,000 cGy higher than other institution, such a low rate of severe complications may suggest that fear of complications should not be overestimated than cure rate and the possibility of more aggressive treatment for better local control should not be underestimated

    Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

    OBJECTIVE To investigate the short-term and long-term therapeutic efficacy of preoperative intra-arterial infusion chemo-embolization on stage IB2-IIB Uterine cervix cancer (UCC). METHODS A total of 143 patients with Stage IB2-lIB UCC were divided into a clinical trial group and a control group. The patients in the clinical trial group (n/=86) were treated with a combined therapy, i.e. preoperative intra-arterial infusion chemo-embolization, surgical therapy and postoperative radiotherapy, and those in the control group(n=57)were given surgical therapy and post-operative radiotherapy. The adverse effects, changes in local lesion and pathological examinations of the cancer, and the state during the surgery were observed after the intra-arterial infusion chemo-embolization. The survival rate and recurrence rate between the two groups were compared. RESUITS The total effective rate of the intra- arterial infusion chemo-embolization on Stage IB2-IIB UCC was 93.02%. The treatment could reduce tumor size, bring about retro-conversions of the clinical stage of the tumors and pathological grade of the cancer cells, and decrease the quantity, of intra-operative blood loss as well as the operating time. It could significantly improve the 5-year survival rate (P<0.05), and reduce the 2 and 5-yeartumor recurrence rates(P<0.05). Moreover, its side effects were little. CONCLUSIOAN Preoperative intra-arterial infusion chemo-embolization can create conditions for radical operation, lower the postoperative recurrence rate, and improve the prognosis in the patients with UCC. It is an effctive therapy in treating UCC.

    Full Text Available Primary non-Hodgkins lymphoma of the uterine cervix is a very rare diagnosis. A 54-year-old woman presented with a 3-month history of postmenopausal bleeding per vaginum. On examination, a friable, fungating lesion was seen on the cervix. Histology revealed a CD 20 positive high-grade non-Hodgkin’s diffuse large B cell lymphoma from cervical biopsies and endometrial curettage. She was diagnosed as stage IE after workup and subsequently treated with six cycles of R-CHOP chemotherapy followed by radiotherapy of the involved field.

  20. High dose rate 60Co remote afterloading irradiation in cancer of the cervix in Haiti, 1977-1984

    International Nuclear Information System (INIS)

    From 1977 through 1984, 293 previously untreated patients with biopsy proven carcinoma of the uterine cervix were treated by whole pelvis irradiation and high intensity 60Co remote afterloading (RAL) intrauterine tandem techniques in Haiti. The treatment results were analyzed retrospectively to evaluate the therapeutic results and prognostic factors of a strict protocol involving 40 Gy to the whole pelvis (2 Gy/day, 5 days/week). In addition, on the 5th day of the 3rd week, the first outpatient 60Co remote afterloading intracavitary insertion, delivering 7.5 Gy to point A with each insertion, repeated 3 times by a week separation for a total of 4 times. The total TDF for external beam plus RAL was 158 and 175 for early and late effects respectively. One hundred-four patients were evaluable after 1 year or more follow-up, with a median of 26.5 months. No evidence of disease (NED) by Stage at 1 year was: Stage I of 100% (3/3), Stage II of 82% (9/11), Stage III of 80% (47/59), and Stage IV of 58% (18/31). The post-therapeutic complication rate was 7.7%, with no fistulas or requirement of surgical intervention. Those with documented follow-up of at least 2 years (74 patients) had comparable survival to other high dose rate and low dose rate studies. This study shows that outpatient brachytherapy can be carried out without sophisticated and expensive equipment with minimal staff trained in radiation therapy. A detailed description of this outpatient RAL technique and results are described so that this method can be adapted to other developing and industrialized nations where cost containment is becoming a key issue

  1. Particularities in the biodistribution and pharmacokinetic of labeled peptide with 99mTc in regional administration of patient with cervix cancer

    International Nuclear Information System (INIS)

    This study had as objective characterize the biodistribution pharmacokinetic and dosimetry of labeled peptide with 99mTc in two dose levels, prepared in 2ml, starting from its intratumoral injection in patient with cervix cancer. The protocol selection to use, the correction and calculate methods were analysis object keeping in mind that antecedents of studies of this type didn't exist and that the administration intratumoral can originate new problems not foreseen in conventional intravenous studies. This study carried out mensurations of sensibility that should be corrected in a particular way. A careful protocol of acquisition was designed able to detect the behavior of the radio-peptide in the time, with a serial gathering of samples of blood and urine until the 24 hours, as well as images of the whole body up to 48h. For the quantification of the images they were necessary also the classic corrections of background and of overlapping of structures. The labeled peptide with 99mTc administered for intralesional way, like it was of waiting it presented a very high reception tumoral, being this maxim in the first images, however the product was absorbed quickly in blood, reaching its maximum levels in most of the patients as much in serum as in total blood, in the first 5-15 minutes of having administered.

  2. Definitive radiotherapy for uterine cervix cancer: long term results for patients treated in the period from 1998 till 2002 at the Institute of Oncology Ljubljana

    International Nuclear Information System (INIS)

    The aim of this retrospective study was to analyse results of the two-dimensional (2D) uterine cervix cancer treatment at the Institute of Oncology Ljubljana from 1998 till 2002, before the three-dimensional (3D) approach was introduced in our clinical practice. Ninety-eight patients with the following FIGO stage distribution were analysed: 10% IB, 7% IIA, 37% IIB, 4% IIIA and 42% IIIB. The influence of age, haemoglobin level, histology, grade, stage, lymph node status, cumulative point A dose, and an overall treatment time on the survival and local control (LC) were evaluated. Acute and late side effects were assessed. Five and 8-year overall survival (OS), disease specific survival (DSS) and LC rate were as follows: 47.2% and 43.0%, 54.7% and 53.4%, 74.9% and 72.5%, respectively. Point A dose and histology of the tumour influenced OS, positive lymph nodes DSS and point A dose LC rate. Probability of grade three and four late complications in the first five years was 7.1% for gastrointestinal tract and 3.3% for genitourinary system and vagina. Point A dose was independent predictor of OS and LC rate, lymph node status predicted DSS, while histology of the tumour influenced OS

    The work focuses on a unique medical repository of digital Uterine Cervix images ("Cervigrams") collected by the National Cancer Institute (NCI), National Institute of Health, in longitudinal multi-year studies. NCI together with the National Library of Medicine is developing a unique web-based database of the digitized cervix images to study the evolution of lesions related to cervical cancer. Tools are needed for the automated analysis of the cervigram content to support the cancer research. In recent works, a multi-stage automated system for segmenting and labeling regions of medical and anatomical interest within the cervigrams was developed. The current paper concentrates on incorporating prior-shape information in the cervix region segmentation task. In accordance with the fact that human experts mark the cervix region as circular or elliptical, two shape models (and corresponding methods) are suggested. The shape models are embedded within an active contour framework that relies on image features. Experiments indicate that incorporation of the prior shape information augments previous results.

  5. An evidence-based estimate of the appropriate rate of utilization of radiotherapy for cancer of the cervix

    International Nuclear Information System (INIS)

    Purpose: Current estimates of the proportion of cancer patients who will require radiotherapy (RT) are based almost entirely on expert opinion. The objective of this study was to calculate the proportion of incident cases of cervical cancer that should receive RT by application of an evidence-based approach. Methods and Materials: A systematic review of the literature was done to identify indications for RT for cervical cancer and to ascertain the level of evidence that supported each indication. A survey of Canadian gynecologic oncologists and radiation oncologists who treat cervical cancer was done to determine the level of acceptance of each indication among doctors who practice in the field. An epidemiologic approach was then used to estimate the incidence of each indication for RT in a typical North American population of patients with cervical cancer. Results: The systematic review of the literature identified 29 different indications for RT for cervical cancer. The majority of the 75 experts who responded to the mail survey stated that they 'usually' or 'always' recommended RT in all but one of the clinical situations that were identified as indications for RT on the basis of the systematic review. The analysis of epidemiologic data revealed that, in a typical North American population, 65.4% ± 2.5% of cervical cancer cases will develop one or more indications for RT at some point in the course of the illness, 63.4% ± 2.3% will develop indications for RT as part of their initial management, and 2.0% ± 0.9% will develop indications for RT for progressive or recurrent disease. The effects of variations in case mix on the need for RT was examined by sensitivity analysis, which suggested that the maximum plausible range for the appropriate rate of utilization of RT was 54.3% to 67.9%. The proportion of cases that required RT was stage dependent: 10.6% ± 1.2% in Stage IA, 74.9% ± 1.3% in Stage IB, 100% in Stages II and III, and 97.2% ± 1.1% in Stage IV

    Purpose: To establish dose-response relationships for late side effects of the rectum and bladder in cervix cancer patients after magnetic resonance image-guided adaptive brachytherapy (IGABT). Methods and Materials: A cohort of 141 patients was treated with 45 to 50.4 Gy with or without cisplatin plus 4 fractions of 7 Gy IGABT. Doses for the most exposed 2, 1, and 0.1-cm{sup 3} (D{sub 2cc}, D{sub 1cc}, D{sub 0.1cc}) volumes of the rectum and bladder were converted into the equivalent dose in 2 Gy fractions (EQD2), using a linear quadratic model ({alpha}/{beta} = 3 Gy). Late side effects were prospectively assessed (using late effects in normal tissues subjective, objective, management and analytic [LENT SOMA]) scales. Dose-response relationships were determined by logit analyses. Results: Eleven patients developed rectal side effects, and 23 patients had urinary side effects. A significant dose effect was found for all rectal dose-volume histogram (DVH) parameters for patients with side effect grades of 1 to 4 but was only significant for D{sub 2cc} and D{sub 1cc} for grades {>=}2. The ED10 values for D{sub 2cc} were 73 Gy for grades 1 to 4 and 78 Gy for grades 2 to 4 rectal morbidity. For bladder side effects, a significant dose effect was shown for all DVH parameters for complication grades {>=}2; the respective ED10 was 101 Gy. Conclusions: Well-defined dose-response curves could be established for D{sub 2cc} in the rectum and the urinary bladder.

    Purpose : In spite of recent remarkable improvement of diagnostic imaging modalities such as CT, MRI, and PET and radiation therapy planing systems, ICR plan of uterine cervix cancer, based on recommendation of ICRU38(2D film-based) such as point A, is still used widely. A 3-dimensional ICR plan based on CT image provides Dose-Volume Histogram(DVH) information of the tumor and normal tissue. In this study, we compared tumor-dose, rectal-dose and bladder-dose through an analysis of DVH between CTV plan and ICRU38 plan based on CT image. Method and Material : We analyzed 11 patients with a cervix cancer who received the ICR of Ir-192 HDR. After 40Gy of external beam radiation therapy, ICR plan was established using PLATO(Nucletron) v.14.2 planning system. CT scan was done to all the patients using CT-simulator(Ultra Z, Philips). We contoured CTV, rectum and bladder on the CT image and established CTV plan which delivers the 100% dose to CTV and ICRU plan which delivers the 100% dose to the point A. Result : The volume(average{+-}SD) of CTV, rectum and bladder in all of 11 patients is 21.8{+-}6.6cm{sup 3}, 60.9{+-}25.0cm{sup 3}, 111.6{+-}40.1cm{sup 3} respectively. The volume covered by 100% isodose curve is 126.7{+-}18.9cm{sup 3} in ICRU plan and 98.2{+-}74.5cm{sup 3} in CTV plan(p=0.0001), respectively. In (On) ICRU planning 22.0cm{sup 3} of CTV volume was not covered by 100% isodose curve in one patient whose residual tumor size is greater than 4cm, while more than 100% dose was irradiated unnecessarily to the normal organ of 62.2{+-}4.8cm{sup 3} other than the tumor in the remaining 10 patients with a residual tumor less than 4cm in size. Bladder dose recommended by ICRU 38 was 90.1{+-}21.3% and 68.7{+-}26.6% in ICRU plan and in CTV plan respectively(p=0.001) while rectal dose recommended by ICRU 38 was 86.4{+-}18.3% and 76.9{+-}15.6% in ICRU plan and in CTV plan, respectively(p=0.08). Bladder and rectum maximum dose was 137.2{+-}50.1%, 101.1{+-}41.8% in ICRU plan

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid {sup 99m}Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

  9. The role of polymorphisms of genes repair pathway to the radiotoxicity in patients with cancer of the cervix

    International Nuclear Information System (INIS)

    Background: In Brazil, cervical cancer is the second most common among women. Radiation therapy is part of its interdisciplinary management, playing an important role in their loco regional control. The major challenge of modern medicine in radiotherapy is to develop predictive methods that can determine the level of radiosensitivity of the patient and the healthy surrounding tissue in order to individualize the prescribed radiation dose, to prevent severe side effects and promoting better local tumor control. This study evaluated the acute and chronic adverse effects on the skin, lower gastrointestinal tract and urinary tract of radiotherapy in 47 cervical cancer patients. Methods and Materials: Biological material was collected and DNA from peripheral blood was extracted of ali patients studied. The fragments of TP53 and ATM were amplified to be sequenced, to verify if there are any polymorphisms witch could be responsible to the radiosensitivity of the patients. Results and Discussion: In a univariate analysis, the variable age was strongly associated with a risk of acute toxicity skin (p=O,023). Patients that received a high dose of external beam radiation and patients who have undergone brachytherapy, showed a significantly higher incidence of chronic urinary tract toxicity (p=O,031) and (p=O,019), respectively. The exchange G>A in the position 5557 of the A TM gene was significantly associated with the risk of acute lower gastrointestinal tract (p=O,008). There wasn't association between the other TP53 polymorphisms analyzed and the frequency of side effects (p>O,05). Our data revealed that patients who evolved significant association presented death (p=O,019) with the increase of chronic skin radiossensitivity. Conclusions: These observations corroborate the importance of investigating the genetic profile to predict adverse side effects in cervical cancer patients undergoing radiotherapy. These genes have an important role in DNA repair pathways and probably

    Cervical cancer is the second most common cause of cancer related morbidity and mortality in women with 50% mortality rate. It is preventable if cervical cellular changes are detected and managed at early stage. This was a retrospective study conducted at VIA center of outpatient department and Colposcopy clinic at in-patient department of Mymensingh Medical College Hospital, Bangladesh covering a period from September 2013 to November 2014. Objective of this study was detection of cervical cancer and precancerous condition amongst patients reported to VIA center and Colposcopy clinic. In primary screening at VIA Center, total respondents were 3604, their mean age was 35.9 and highest were in the age group 31 to 40 years. At VIA center, 110(3.05%) were found positive and highest were between 31 to 40 years. In Colposcopy Clinic, out of 700 patients, 51.7% were CIN 1, 4.9% CIN 2, 1.4% CIN 3, invasive carcinoma was 0.3% and unsatisfactory or inconclusive were 34.3%. Most of the respondents were housewives and majority had poor monthly income. Amongst respondents, 72.1% were from rural area and Colposcopic findings revealed in 62.5% abnormal cervical changes, 46.5% were from rural area. Mean age at marriage or age at first coitus was found 16.25 years and 92.7% were in 11 to 20 years. Maximum abnormal cervical findings including CIN were between the ages ranged from 11 to 20 years of marriage age. In patients having 1 - 5 number of child having abnormal (58%) cervical changes, 48% were CIN 1. Histopathology reports found 19.6% CIN 1 (Total CIN 20.7%), cervical carcinoma 1.3%, inflammatory 7.0% and 0.42% cases were reported normal. Amongst 438 histopathology advised cases, 230 respondent's reports with patients were not available. VIA followed by Colposcopy has been a feasible, easy and reliable tools for screening cervical cancer in Bangladesh. PMID:27612882

  11. Uterine cervix cancer treatment at Radiumhemmet: 90 years′ experience. Time trends of age, stage, and histopathology distribution

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

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

    2013-10-15

    Purpose: To investigate the impact of magnetic resonance imaging (MRI)-morphologic differences in parametrial infiltration on tumour response during primary radio chemotherapy in cervical cancer. Material and methods: Eighty-five consecutive cervical cancer patients with FIGO stages IIB (n = 59) and IIIB (n = 26), treated by external beam radiotherapy ({+-}chemotherapy) and image-guided adaptive brachytherapy, underwent T2-weighted MRI at the time of diagnosis and at the time of brachytherapy. MRI patterns of parametrial tumour infiltration at the time of diagnosis were assessed with regard to predominant morphology and maximum extent of parametrial tumour infiltration and were stratified into five tumour groups (TG): 1) expansive with spiculae; 2) expansive with spiculae and infiltrating parts; 3) infiltrative into the inner third of the parametrial space (PM); 4) infiltrative into the middle third of the PM; and 5) infiltrative into the outer third of the PM. MRI at the time of brachytherapy was used for identifying presence (residual vs. no residual disease) and signal intensity (high vs. intermediate) of residual disease within the PM. Left and right PM of each patient were evaluated separately at both time points. The impact of the TG on tumour remission status within the PM was analysed using {chi}2-test and logistic regression analysis. Results: In total, 170 PM were analysed. The TG 1, 2, 3, 4, 5 were present in 12%, 11%, 35%, 25% and 12% of the cases, respectively. Five percent of the PM were tumour-free. Residual tumour in the PM was identified in 19%, 68%, 88%, 90% and 85% of the PM for the TG 1, 2, 3, 4, and 5, respectively. The TG 3 - 5 had significantly higher rates of residual tumour in the PM in comparison to TG 1 + 2 (88% vs. 43%, p < 0.01).

    Objective: To evaluate an alternative brachytherapy technique for uterine cervix cancer involving the distal vagina, without increasing the risk of toxicity. Materials And Methods: Theoretical study comparing three different high-dose rate intracavitary brachytherapy applicators: intrauterine tandem and vaginal cylinder (TC); tandem/ring applicator combined with vaginal cylinder (TR+C); and a virtual applicator combining both the tandem/ring and vaginal cylinder in a single device (TRC). Prescribed doses were 7 Gy at point A, and 5 Gy on the surface or at a 5 mm depth of the vaginal mucosa. Doses delivered to the rectum, bladder and sigmoid colon were kept below the tolerance limits. Volumes covered by the isodoses, respectively, 50% (V50), 100% (V100), 150% (V150) and 200% (V200) were compared. Results: Both the combined TR+C and TRC presented a better dose distribution as compared with the TC applicator. The TR+C dose distribution was similar to the TRC dose, with V150 and V200 being about 50% higher for TR+C (within the cylinder). Conclusion: Combined TR+C in a two-time single application may represent an alternative therapy technique for patients affected by uterine cervix cancer involving the distal vagina. (author)

    Cervicography is a technique for visual screening of uterine cervix images for cervical cancer. One of our research goals is the automated detection in these images of acetowhite (AW) lesions, which are sometimes correlated with cervical cancer. These lesions are characterized by the whitening of regions along the squamocolumnar junction on the cervix when treated with 5% acetic acid. Image preprocessing is required prior to invoking AW detection algorithms on cervicographic images for two reasons: (1) to remove Specular Reflections (SR) caused by camera flash, and (2) to isolate the cervix region-of-interest (ROI) from image regions that are irrelevant to the analysis. These image regions may contain medical instruments, film markup, or other non-cervix anatomy or regions, such as vaginal walls. We have qualitatively and quantitatively evaluated the performance of alternative preprocessing algorithms on a test set of 120 images. For cervix ROI detection, all approaches use a common feature set, but with varying combinations of feature weights, normalization, and clustering methods. For SR detection, while one approach uses a Gaussian Mixture Model on an intensity/saturation feature set, a second approach uses Otsu thresholding on a top-hat transformed input image. Empirical results are analyzed to derive conclusions on the performance of each approach.

    Full Text Available BACKGROUND: Cervical cancer is the leading cause of cancer related deaths among women in India. Limited reports are available for Notch-1 and Notch-3 protein in cervical carcinoma, which play crucial role in cell proliferation, differentiation, and apoptosis. METHODS: This study was designed to evaluate the role of Notch-1 and Notch-3 with context to HPV infection in cervical carcinoma. A total of 168 tissue biopsy samples comprising of tumor specimens (n = 98, precancer (n = 30 and non-neoplastic cervical tissues (n = 40 were screened for HPV infection by PCR and expression of Notch-1 and Notch-3 protein by Immunohistochemistry and Immunoblotting. RESULTS: 80% (24/30 were found to be positive for HPV in precancer and 86.7% (85/98 in cancer patients. Notch-1 expression of precancer and cancer cases was found to be significantly down-regulated with severity of disease in nuclear (3.43±0.29; 2.04±0.19, p = 0.0001, p = 0.0001 and cytoplasm (3.07±0.29; 2.29±0.17, p = 0.0001, p = 0.0001 obtained from different stages as compared to normal cervix tissue (5.40±0.19, 4.97±0.15; p<0.001; p<0.001. However, Notch-3 expression of above cases was significantly up-regulated with severity of disease and showed intense nuclear (4.17±0.39; 4.74±0.18, p = 0.0001, p = 0.0001 and cytoplasm (3.67±0.36; 4.48±0.18, p = 0.0001, p = 0.0001 of different stages as compared to normal cervix tissue (0.95±0.20, 0.70±0.20; p<0.001; p<0.001 respectively. CONCLUSIONS: These findings suggest that Notch-1 and Notch-3 may play an important role with synergistic effect of HPV in regulating development and proliferation of cervical cancer through the deregulation of Notch signalling. This study also shows the clinical utility of both proteins which may be used as predictable biomarkers in diagnosing different histological sub-types of HPV associated cervical cancer. Nevertheless, abnormal activation of this pathway may provide

    In this work we focus on the generation of reliable ground truth data for a large medical repository of digital cervicographic images (cervigrams) collected by the National Cancer Institute (NCI). This work is part of an ongoing effort conducted by NCI together with the National Library of Medicine (NLM) at the National Institutes of Health (NIH) to develop a web-based database of the digitized cervix images in order to study the evolution of lesions related to cervical cancer. As part of this effort, NCI has gathered twenty experts to manually segment a set of 933 cervigrams into regions of medical and anatomical interest. This process yields a set of images with multi-expert segmentations. The objectives of the current work are: 1) generate multi-expert ground truth and assess the diffculty of segmenting an image, 2) analyze observer variability in the multi-expert data, and 3) utilize the multi-expert ground truth to evaluate automatic segmentation algorithms. The work is based on STAPLE (Simultaneous Truth and Performance Level Estimation), which is a well known method to generate ground truth segmentation maps from multiple experts' observations. We have analyzed both intra- and inter-expert variability within the segmentation data. We propose novel measures of "segmentation complexity" by which we can automatically identify cervigrams that were found difficult to segment by the experts, based on their inter-observer variability. Finally, the results are used to assess our own automated algorithm for cervix boundary detection.

    In Nepal, while no population based cancer registry program exists to assess the incidence, prevalence, morbidity and mortality of cancer, at the national level a number of hospital based cancer registries are cooperating to provide relevant data. Seven major cancer diagnosis and treatment hospitals are involved, including the BP Koirala Memorial Cancer hospital, supported by WHO-Nepal since 2003. The present retrospective analysis of cancer patients of all age groups was conducted to assess the frequencies of different types of cancer presenting from January 1st to December 31st 2012. A total of 7,212 cancer cases were registered, the mean age of the patients being 51.9 years. The most prevalent age group in males was 60-64 yrs (13.6%), while in females it was 50-54 yrs (12.8%). The commonest forms of cancer in males were bronchus and lung (17.6%) followed by stomach (7.3%), larynx (5.2%) and non Hodgkins lymphoma (4.5%). In females, cervix uteri (19.1%) and breast (16.3%), were the top ranking cancer sites followed by bronchus and lung (10.2%), ovary (6.1%) and stomach (3.8%). The present data provide an update of the cancer burden in Nepal and highlight the relatively young age of breast and cervical cancer patients. PMID:26745133

    Data from 20 years of cancer registration in Harare (Zimbabwe) are used to investigate the risk of cancer in the white population of the city (of European origin), relative to that in blacks (of African origin). In the absence of information on the respective populations-at-risk, we calculated odds of each major cancer among all cancers, and took the odds ratios of whites to blacks. Some major differences reflect obvious phenotypic differences (the very high incidence of skin cancer-melanoma and nonmelanoma--in the white population), whereas others (high rates of liver cancer, Kaposi sarcoma and conjunctival cancers in blacks) are the result of differences in exposure to infectious agents. Of particular interest are cancers related to lifestyle factors, and how the differences in risk are changing over time, as a result of evolving lifestyles. Thus, the high risk of cancers of the esophagus and cervix uteri in blacks (relative to whites) and colorectal cancers in whites show little change over time. Conversely, the odds of breast cancer, on average four times higher in whites than blacks, has shown a significant decrease in the differential over time. Cancer of the prostate, with the odds initially (1991-1997) 15% higher in whites had become 33% higher in blacks by 2004-2010. PMID:26437451

  8. Value and importance of intracavitary therapy in uterine cervix carcinoma

    International Nuclear Information System (INIS)

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

    Full Text Available Abstract Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII and the Slope Index of Inequalities (SII. All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003. Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

    Secondary metastatic tumours of the uterine cervix are rare. There have been no reports of duodenal cancer metastasizing to the uterine cervix. Here we present a rare case of an extra-ampullary duodenal adenocarcinoma that has metastasized to the uterine cervix. The patient was a 71-year-old woman who had surgery for an extra-ampullary duodenal adenocarcinoma five years previously. Follow-up examination revealed a suspicious right ovarian mass and nodules in the cervix and posterior fornix of the vagina. Biopsies suggested squamous cell carcinoma in the cervix and adenocarcinoma in the fornix. Intraoperatively, the right ovary was enlarged and peritoneal disseminations were found in the pouch of Douglas and the sigmoid colon mesentery. Histopathology of the subsequent hysterectomy and bilateral salpingo-oophorectomy specimen revealed a cervical squamous cell carcinoma categorized as pT1b1. Adenocarcinoma infiltration into the ovaries, uterine cervix and vagina, with vascular involvement was detected. Immunohistochemistry revealed the tumour in the cervix and ovaries to be positive for CK7, MUC5AC and MUC6, and immunonegative for CK20, CDX2, Pax8, ER, MUC2 and CD10, similar to the original duodenal adenocarcinoma. This case illustrates the difficulty in making a preoperative diagnosis of metastatic adenocarcinoma in the uterine cervix with a coexisting primary cervical squamous cell carcinoma. The absence of atypia in cervical glandular cells and immunohistochemical profiling of the adenocarcinoma clusters helped to reach a final diagnosis. This is the first report of an extra-ampullary duodenal adenocarcinoma metastasis to the uterine cervix. PMID:27126664

    From September 1989 to December 1992, 178 patients with cervix cancer were treated with radiation therapy alone, being 81 stage IIIB patients were randomized according to the number of intracavitary brachytherapy insertion realized after external irradiation. Of these, 34 were treated with two intracavitary insertion (group A) and 47 with one insertion (group B). Among stage IIIB patients, 54 were treated with one intracavitary insertion after external irradiation (group C) and 47 with external irradiation alone as they had no geometrical condition for intracavitary insertion (group D). There were no statistical difference in 50 months disease free survival among patients stage IIB treated with one or two intracavitary insertion, 72,3% and 70.6% respectively (P=0,711). The 50 months disease free survival were better in patients stage IIIB treated with external irradiation followed by one intracavitary insertion, compared with those treated with external irradiation alone, 51,8% and 30,2% respectively (P=0,007). This series suggests that there is no difference in the treatment of stage IIB cervix cancer with one or two intracavitary insertion. Among stage IIIB patients, the worse result of those treated with external irradiation alone was probably due to the unfavorable prognostic factors, as they were excluded for brachytherapy because they showed no geometrical condition for intracavitary insertion and larger tumor volume.

    Abstract During pregnancy the firm cartilage-like consistency of the cervix is transformed to soft tissue. This transformation is called "cervical ripening" and enables the cervix to dilate and facilitate parturition. In 1960, the Bishop Score was introduced to assess cervical ripeness before induction of labour, which is determined by digital examination. The Bishop Score consists of five different aspects of the cervix, namely dilatation, effacement, consistency, position and station of the...

    Of the 2,635,000 new cancer cases (excluding non-melanoma skin cancers) occurring in the European Union (EU) in 2012, it is estimated that approximately 185,000 are related to infection with human papillomaviruses (HPVs), hepatitis B and C viruses (HBV and HCV), and Helicobacter pylori (H. pylori). Chronic infection with these agents can lead to cancers of the cervix uteri, liver, and stomach, respectively. Chronic infection with HCV can also lead to B-cell non-Hodgkin lymphoma. Human immunodeficiency virus (HIV) infection continues to be of major public health importance in several EU countries and increases cancer risk via HIV-induced immunosuppression. The fourth edition of the European Code Against Cancer presents recommendations on effective and safe preventive interventions in order to reduce the risk of infection-related cancers in EU citizens. Based on current available evidence, the fourth edition recommends that parents ensure the participation of their children in vaccination programs against HBV (for newborns) and HPV (for girls). In the 'Questions and Answers' (Q&As) section about vaccination and infections in the website for the European Code Against Cancer, individuals who are at risk of chronic HBV or HCV are advised to seek medical advice about testing and obtaining treatment when appropriate. Individuals most at risk of HIV are advised to consult their doctor or healthcare provider to access counselling and, if needed, testing and treatment without delay. Information about H. pylori testing and treatment is also provided as testing might currently be offered in some high-risk areas in Europe. The rationale and supporting evidence for the recommendations on vaccination in the European Code Against Cancer, and for the main recommendations on vaccination and infection in the Q&As, are explained in the present review.

  17. Mortality from cancers of major sites in female radium dial workers

    International Nuclear Information System (INIS)

    The female radium dial workers have now experienced significant mortality from cancers other than the bone sarcomas and head carcinomas long known to be radium induced. The relationships of radium exposure to mortality from cancers of the stomach, pancreas, colon, rectum, liver, lung, breast, cervix, and corpus uteri, and from leukemia were studied in 1,285 pre-1930 dial workers. Mortality was compared with that expected from rates for US white females, with and without adjustment for local area mortality rates, and with mortality in dial workers exposed from 1930 to 1949. For the 693 cases whose body content of radium has been measured since 1955, dose-response relationships of cancer to systemic intake of radium and duration of employment were examined. Liver, pancreatic, cervical, and uterine cancers were clearly unrelated to radium exposure. Other cancers of the digestive tract appeared to be indirectly, if at all, associated with work in radium facilities. Lung cancer requires further investigation; inhalation exposures of the dial workers were reviewed. Analyses of the breast cancer data uncovered several observations inconsistent with the previously suggested causal association with radium exposure. Multiple myeloma was also reviewed. A threefold excess risk of death due to multiple myeloma has occurred, but is more closely correlated with duration of employment (a surrogate for external gamma radiation) than with radium intake

  18. Oncologic imaging for carcinoma of the cervix, ovary and endometrium

    International Nuclear Information System (INIS)

    Ninety percent of neoplasms of the cervix are epidermoid carcinomas. Most of the remaining 10% is accounted for by adenocarcinomas; sarcomas of the cervix are rare lesions with a very poor prognosis. Grading of the microscopic specimens obtained from patients with epidermoid carcinomas generally follows the standard three-grade system, viz, well, moderately, and poorly differentiated cellular structure. While the degree of differentiation may have less influence on overall survival than does stage and bulk of the primary lesion, there are studies that indicate that patients with high grade lesions have a poorer prognosis. In Chung's series, for example, the incidence of nodal metastases in patients with stage IB squamous cancers was 0% for grade 1, 18% for grade 2, and 50% for grade 3 lesions. Similarly, the two year survival in the same stage was 100%, 93%, and 77% for grades 1, 2 and 3, respectively

To that effect, the National Cancer Registry of The Gambia (NCR, a population-based cancer registry (PBCR, was established in 1986 to actively collect data on all cancer diagnosis nation-wide. We extracted 20-years (1990-2009 of data to assess for the first time, the evolution of the most common cancers, also describe and demonstrate the role of the PBCR in a hepatitis B and liver cancer prevention programme in this population. METHODS AND FINDINGS: We estimated Age-Standardised Incidence Rates (ASR (W of the most common cancers registered during the period by gender. The registration period was divided into four 5-year intervals and incidence rates were estimated for each interval. The most common cancers in males were liver, prostate, lung plus bronchus, non-Hodgkin lymphoma (NHL and stomach, accounting for 60%, 5%, 4%, 5% and 3%, respectively. Similarly, cancers of the cervix uteri, liver, breast and NHL, were the most common in females, accounting for 33%, 24%, 11% and 4% of the female cancers, respectively. CONCLUSIONS: Cancer incidence has remained relatively stable over time, but as shown elsewhere in sub-Saharan Africa the disease is a threat in The Gambia. The infection related cancers which are mostly preventable (HBV in men and HPV/HIV in women were the most common. At the moment the data is not enough to detect an effect of hepatitis B vaccination on liver cancer incidence in The Gambia. However, we observed that monitoring case occurrence through PBCR is a key public health pre-requisite for rational planning and implementation of targeted interventions for improving the health of the population.

  20. Clear cell adenocarcinoma of the ulterine cervix in a 15 year old girl: A case report

    International Nuclear Information System (INIS)

    Cervical cancer is rare in the pediatric population. In cases of cervical cancer, adenocarcinoma is predominantly reported. Clear cell adenocarcinoma (CCAC) of the uterine cervix is a very rare tumor and accounts for only 4% of all adenocarcinomas of the uterine cervix. Risk factors and pathogenesis of this disease are not exactly revealed. The intrauterine exposure to diethylstilbestrol (DES) and associated non-steroidal estrogen during pregnancy before 18 weeks is the only known risk factor. This study reports the imaging finding of primary uterine cervical tumor in a 15-year-old girl, who was finally diagnosed with CCAC, with no maternal history of DES exposure in utero.

    Full Text Available Abstract Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670. More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias.

  5. In vivo and in vitro experimental study on cervix cancer with combination of HSV-TK/GCV suicide gene therapy system and 60Co radiotherapy

    International Nuclear Information System (INIS)

    Objective: To evaluate the killing effect of HSV-TK/GCV suicide gene therapy system combined with 60Co radiotherapy on human cervical cancer HeLa cell line in vivo and in vitro, and to explore radiosensitization by the HSV-TK/GCV system. Methods: The HSV-TK/GCV suicide gene therapy system and 60Co radiotherapy were used separately or in combination for human cervical cancer HeLa cell line in vivo and in vitro to compare their effects. Colony formation test and the rate of radiosensitization effect(E/O) were employed to observed the radiosensitization by the HSV-TK/GCV system. Results: The HSV-TK/GCV suicide gene therapy system showed strong therapeutic effects on HeLa cells both in vitro and in vivo (the inhibition rates were 45.8% and 39.5%, respectively). Moreover, the combined application of gene therapy and radiotherapy exhibited stronger therapeutic effects in vitro and in vivo (the inhibition rate was 87.5% in vitro, and was 87.9% in vivo) (P 1.4), indicating the HSV-TK/GCV system could exert a sensitizing effect on 60Co radiotherapy of the transplanted human cervical cancer cells in nude mice. Conclusion: The HSV-TK/GCV system has radiosensitizationaction. Gene therapy combined with radiotherapy may be a good supplementary method for synthetic treatment of cervical cancer. (authors)

    Full Text Available Abstract Introduction Pulmonary metastasis presenting as lymphangitic carcinomatosis arising from squamous cell carcinoma (SCC of the cervix is a rare event. Poorly represented in the literature, this event is associated with a difficulty in accurate diagnosis, b grave prognosis, and the c lack of recognized predisposing risk factors. Case Report A 50 year-old female presented at our practice with a three-month history of a productive cough associated with dyspnoea and shortness of breath. A chest x-ray and computed tomography (CT scan revealed multiple bilateral patchy areas with subsegmental atelectasis in both lungs which was investigated with a bronchoscopy, left thoracoscopy, and a left lung biopsy. Pathological examination of the wedge biopsy of the left upper lobe revealed neoplastic sheets of cell disturbed along the septal vessels, perivascular/peribronchial lymphatics, and the subpleural lymphatics. This lymphangitic carcinomatosis was confirmed to be metastatic from SCC of the cervix that had been diagnosed and treated two years ago. She was treated with systemic Carbo/Taxol chemotherapy and corticosteroids as a palliative measure. Despite temporary improvement, she died 13 months later. Conclusion Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic SCC of the cervix. As clinical presentations including radiographic imaging mimics other pulmonary entities, accurate diagnosis remains a challenge. Increased clinical awareness of such patterns of metastases in cervical cancer supported by accurate pathological diagnosis is imperative to guide appropriate therapy in these patients.

  7. The Role of 18F-FDG PET/CT in Assessing Therapy Response in Cervix Cancer after Concurrent Chemoradiation Therapy

    International Nuclear Information System (INIS)

    To determine whether persisting cervical fluorodeoxyglucose (FDG) uptake after concurrent chemoradiotherapy (CCRT) for cervical cancer can reflect residual malignancy. F-FDG PET/CT was performed before and after CCRT in 136 patients with cervical cancer. The maximum and mean standardized uptake values (SUVmax and SUVmean) were recorded from PET/CT scans performed pre- and post-treatment. SUVs were correlated with treatment response after CCRT. Final treatment response was determined by MRI and further follow-up PET/CT. One hundred four of 136 patients underwent pelvic MRI, and 32 of 136 patients underwent further follow-up PET/CT. Patients were classified into two categories: patients with residual tumor or patients without residual tumor (complete responder). Preand post-treatment serum squamous cell carcinoma antigen (SCC) levels were also recorded for comparison. The optimal cutoff value of SUVmax for predicting residual cervical tumor was determined using receiver-operating characteristic (ROC) analysis. Of 136 patients, 124 showed complete response on further follow-up studies and 12 were confirmed to have residual tumor. The post-treatment SUVmax and pre-/posttreatment SUVmean of complete responders were significantly lower than those of patients with residual tumor: 2.5±0.8 and 7.2±4.2/1.9±0.7 for complete responders and 5.7±2.6 and 12.8±6.9/3.7±0.7 for patients with residual tumor (p 18F-FDG PET/CT after CCRT for cervical cancer may be caused by residual tumor or post-therapy inflammation. A higher cutoff SUVmax than conventional criteria for cervical cancer in post-CCRT PET/CT might help to detect residual tumor

  9. Long-Term Improvement in Treatment Outcome After Radiotherapy and Hyperthermia in Locoregionally Advanced Cervix Cancer: An Update of the Dutch Deep Hyperthermia Trial

    International Nuclear Information System (INIS)

    Purpose: The local failure rate in patients with locoregionally advanced cervical cancer is 41-72% after radiotherapy (RT) alone, whereas local control is a prerequisite for cure. The Dutch Deep Hyperthermia Trial showed that combining RT with hyperthermia (HT) improved 3-year local control rates of 41-61%, as we reported earlier. In this study, we evaluate long-term results of the Dutch Deep Hyperthermia Trial after 12 years of follow-up. Methods and Materials: From 1990 to 1996, a total of 114 women with locoregionally advanced cervical carcinoma were randomly assigned to RT or RT + HT. The RT was applied to a median total dose of 68 Gy. The HT was given once weekly. The primary end point was local control. Secondary end points were overall survival and late toxicity. Results: At the 12-year follow-up, local control remained better in the RT + HT group (37% vs. 56%; p = 0.01). Survival was persistently better after 12 years: 20% (RT) and 37% (RT + HT; p = 0.03). World Health Organization (WHO) performance status was a significant prognostic factor for local control. The WHO performance status, International Federation of Gynaecology and Obstetrics (FIGO) stage, and tumor diameter were significant for survival. The benefit of HT remained significant after correction for these factors. European Organization for Research and Treatment of Cancer Grade 3 or higher radiation-induced late toxicities were similar in both groups. Conclusions: For locoregionally advanced cervical cancer, the addition of HT to RT resulted in long-term major improvement in local control and survival without increasing late toxicity. This combined treatment should be considered for patients who are unfit to receive chemotherapy. For other patients, the optimal treatment strategy is the subject of ongoing research

The pre-treatment SUVmax and pre-/post-treatment serum SCC levels of the complete responders tended to be lower than those of patients with residual tumor, but this did not have statistical significance. Using ROC analysis, an optimal cutoff SUVmax of 4.0 on the post-treatment PET/CT yielded a sensitivity, specificity, positive predictive value, and negative predictive value of 92 %, 94 %, 61 %, and 99 %, respectively (p <0.001).

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

    International Nuclear Information System (INIS)

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

    Tobacco use is a well-established risk factor for many types of cancers. Recent data on selected cancer incidence and mortality related to smoking in the Indonesian population are provided in this study. Morbidity and mortality data were derived from GLOBOCAN 2012 and the population attributable fraction (PAF) was estimated using the standard methodology developed by the World Health Organization. Using these data, we calculated disability adjusted life year (DALY) values for smoking-related cancer. The DALY was estimated by summation of the years lived with disability (YLD) and years life lost due to premature death (YLL). The cancer cases related to smoking in Indonesia numbered 45,132, accounting for 35,580 cancer deaths. The morbidity and mortality of lung cancer can be considered as the highest priority in both men and women. Furthermore the greatest YLD due to smoking in Indonesian men and women were from pancreas and lung cancers. For YLL among men, the highest years lost were from lung and liver cancers. On the other hand, among women lung oral cavity and lip were most important. Based on the DALY indicator, burden priorities for Indonesian men were lung cancer (298,980), liver cancer (60,367), and nasopharynx (46,185), while among Indonesian women they were lung cancer (34,119), cervix uteri (9,213) and pancreas cancer (5,433). In total, Indonesian burden of cancers attributed to smoking was 638,682 DALY. This study provides evidence about the burden of cancers caused by smoking as a rational basis for initiating national tobacco control policies in Indonesia. PMID:27039808

    International Nuclear Information System (INIS)

    The prognostic importance of various pretherapeutic and therapeutic factors was analysed in a group of 413 cervical cancer patients with stage IIB (183 pts) and IIIB (230 pts) treated with radical radiotherapy, which consisted of external irradiation and intracavitary brachytherapy. Univariate analysis of pretherapeutic factors revealed the prognostic significance of patient age, history of abortion, stage, haemoglobin and hematocrit levels. Five-year overall survival rate in stage IIB patients was 51% in stage IIIB 40% and the respective rates for local control at each stage were 61%, and 46%. Univariate analysis of therapeutic factors showed that survival and local control rates increased with the dose, but a significant difference was found only in the case of a paracentral (point A) dose. In a multivariate analysis only patient age, abortions, and clinical stage appeared to have a significant and independent impact on survival. Linear regression analysis results indicated that prolongation of treatment time between 33 and 108 days caused a loss of local control of 0.36% per day. (orig.)

    Purpose: In premise of uninfluenced to dose distribution of tumor target and organ at risk(OAR) in cervical cancer,area of segment fields was changed to increase efficacy and optimize treatment method by designing different plan of intensity modulated radiotherapy(IMRT). Methods: 12 cases of cervical cancer were confirmed in pathology and treated with step and shoot IMRT. Dose of PTV was 50Gy/25fractions. Every patient was designed 9 treatment plans of IMRT by Pinnacle 8.0m planning system,each plan was used with 9 beams of uniform distribution and fixing incidence direction(200°,240°,280°,320°,0°,40°,80°,120°and 160°respectively),and designed for delivery on Elekta Synergy linear accelerator. All plans were optimized with the direct machine parameter optimization(DMPO) algorithm using the same set of optimization objectives. Number of maximum segment field was defined at 80 and minimum MU in each segment was 5MU,and minimal segment area was 2*1cm{sup 2},2*2cm{sup 2},3*3cm{sup 2},4*4cm{sup 2},5*5cm{sup 2},6*6cm{sup 2},7*7cm{sup 2},8*8cm{sup 2}and 9*9cm{sup 2},respectively.Coverage,homogeneity and conformity of PTV,sparing of OAR, MU and number of segment were compared. Results: In this group, mean volume of PTV was 916.8±228.7 cm{sup 3}. Compared with the area of minimal segment field increased from 2*1cm{sup 2} to 9*9 cm{sup 2},the number of mean MU was decreased from 1405±170 to 490±47 and the number of segment field was reduced from 76±4 to 39±7 respectively(p<0.05). When the limit of minimal segment area was increased from 2*1cm{sup 2} to 7*7 cm{sup 2},dose distribution of PTV,OAR,CI,HI and V{sub 2} {sub 3} were not different (p>0.05),but when the minimal segment area was 8*8 cm{sup 2} and 9*9 cm{sup 2},they were changed compared with 7*7 cm{sup 2} and below(p<0.05). Conclusion: The minimal segment field of IMRT plan designed by Pinnacle 8.0m planning system in cervical carcinoma should be enlarge reasonably and minimal segment area of 7*7 cm

    Full Text Available Background: To evaluate the role of VIA alone and in combination with high risk Human Papilloma virus DNA testing as a screening test for cervical dysplasia and cancer. Methods: 400 symptomatic patients from the gynecology outpatient department were screened using Pap smear and VIA. HPV DNA testing was done for 62 VIA positive and 100 VIA negative women. Colposcopy was done for all women. Those found positive on any or all of the screening tests were subjected to cervical biopsy. The results were analysed for PAP, VIA, HPV and a combined test using VIA and HPV both. Results: VIA had the highest sensitivity (91% to detect any grade of dysplasia. The sensitivity of the combination test (VIA + HPV was 80.6% which was lower than that of VIA (91% and also lower than that of HR HPV DNA detection (86%. The specificity of the combination test (VIA + HPV was 68.3 % which was significantly higher than that of VIA alone (39% (p = 0.000 and also higher than that for HPV DNA detection when used alone (56%. Pap smear had the highest specificity (95.12 % but sensitivity was much lower at 52.7 %. Conclusions: VIA is a highly sensitive screening test. The main disadvantage is its low specificity. However the combination test of VIA + HR HPV testing overcomes this and at the same time maintains a high sensitivity. Thus a test which combines VIA plus HR HPV testing is better screening method than either of the three tests (VIA, HPV, PAP done alone. [Int J Reprod Contracept Obstet Gynecol 2013; 2(2.000: 152-156

    To analyze the correlation between dose volume histograms(DVH) based on organ outer wall contour and organ wall delineation for bladder and rectum, and to compare the doses to these organs with the absorbed doses at the bladder and rectum. Individual CT based brachytherapy treatment planning was performed in 13 patients with cervical cancer as part of a prospective comparative trial. The external contours and the organ walls were delineated for the bladder and rectum in order to compute the corresponding dose volume histograms. The minimum dose in 0.1 cm{sup 3}, 1 cm{sup 3}, 2 cm{sup 3}, 5 cm{sup 3}, 10 cm{sup 3} volumes receiving the highest dose were compared with the absorbed dose at the rectum and bladder reference point. Results: The bladder and rectal doses derived from organ outer wall contour and computed for volumes of 2 cm{sup 3}, provided a good estimate for the doses computed for the organ wall contour only. This correspondence was no longer true when large volumes were considered. For clinical applications, when volumes smaller than 5 cm{sup 2} are considered, the dose.volume histograms computed from external organ contours for the bladder and rectum can be used instead of dose.volume histograms computed for the organ walls only. External organ contours are indeed easier to obtain. The dose at the ICRU rectum reference point provides a good estimate of the rectal dose computed for volumes smaller than 2 cm{sup 2} only for a midline position of the rectum. The ICRU bladder reference point provides a good estimate of the dose computed for the bladder wall only in cases of appropriate balloon position.

  4. Intracavitary radiotherapy of cervix carcinoma with flexible applicators after vesicovaginal interposition operation of the uterus

    International Nuclear Information System (INIS)

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

    Purpose: evaluation of the inter- and intraindividual applicator variability of multiple high-dose-rate (HDR) brachytherapy applications for primary treatment of cancer of the uterine cervix. Material and methods: retrospective analysis of 460 pairs of orthogonal X-ray films for conventional treatment in 92 patients with five intrauterine applications using an HDR tandem applicator. Measurement of the position of the applicator origin relative to a bony reference system in three dimensions. Evaluation of the differences of the applicator position in all 460 applications (interindividual variability), of the five applications in a single patient (intraindividual variability) and of the intraindividual variability relative to the applicator position at the first application. Results: the position of the applicator origin in the pelvis ranged from 23 mm cranial and 55 mm caudal to the top of femoral heads, 23 mm right and 27 mm left to the pelvic midline, and 6-53 mm dorsal to the mid of the femoral heads. Standard deviation (SD) of interindividual applicator variability was 12.9 mm (minimum/maximum -55/+23 mm, mean -13.6 mm) in longitudinal, 5.1 mm (-27/+23 mm, mean 1.6 mm) in lateral, and 7.6 mm (6/53 mm, mean 26 mm) in anterior-posterior [AP] direction. SD of intraindividual variability was 5.5 mm (-21/+23 mm, mean 0 mm) in longitudinal, 2.5 mm (-17/+19 mm, mean 0 mm) in lateral, and 4.2 mm (-15/+18 mm, mean 0 mm) in AP direction compared to intraindividual variability relative to the first insertion with an SD of 8.9 mm (-23/+36 mm, mean 2.8 mm) in longitudinal, 4.0 mm (-11/+23 mm, mean 0 mm) in lateral, and 6.8 mm (-27/+17 mm, mean -0.8 mm) in AP direction. Conclusion: intraindividual applicator variability is significantly smaller than interindividual variability. Applicator-related procedures such as midline shielding or dose matching of tele- and brachytherapy should be performed with information on at least one individual applicator position. (orig.)

    Full Text Available Abstract Introduction Persistent Mullerian duct syndrome is a rare form of male pseudo-hermaphroditism characterized by the presence of Mullerian duct structures in an otherwise phenotypically, as well as genotypically, normal man; only a few cases have been reported in the worldwide literature. We report the case of a 30-year-old man with unilateral cryptorchidism on the right side and a left-sided obstructed inguinal hernia containing a uterus and fallopian tube (that is, hernia uteri inguinalis; type I male form of persistent Mullerian duct syndrome coincidentally detected during an operation for an obstructed left inguinal hernia. Case presentation A 30-year-old South Indian man was admitted to our facility with a left-sided obstructed inguinal hernia of one day's duration. He had a 12-year history of inguinal swelling and an absence of the right testis since birth. Our patient had well developed masculine features. Local physical examination revealed a left-sided obstructed inguinal hernia with an absence of the right testis in the scrotum. Exploration of the inguinal canal revealed an indirect inguinal hernia containing omentum, the left corner of the uterus and a left fallopian tube. Extension of the incision revealed a well formed uterus, cervix and upper part of the vagina attached to the prostate by a thick fibrosed band. Total excision of the uterus, bilateral fallopian tubes and right testis was performed. A biopsy was taken from the left testis. The operation was completed by left inguinal herniorraphy. Histopathological examination of the hernial contents was consistent with that of a uterus and fallopian tubes without ovaries. Both testes were atrophied, with complete arrest of spermatogenesis. Post-operative karyotype analyses were negative for 46,XY and Barr bodies on buccal smear. A semen examination revealed azoospermia with a low serum testosterone level. Conclusions In cases of unilateral or bilateral cryptorchidism

    Assessment of Human papillomavirus (HPV) prevalence and genotype distribution is important for monitoring the impact of prophylactic HPV vaccination. This study aimed to demonstrate the HPV genotypes predominating in pre-malignant and cervical cancers in Northern Ireland (NI) before the vaccination campaign has effect. Formalin fixed paraffin embedded tissue blocks from 2,303 women aged 16-93 years throughout NI were collated between April 2011 and February 2013. HPV DNA was amplified by PCR and HPV genotyping undertaken using the Roche(®) linear array detection kit. In total, 1,241 out of 1,830 eligible samples (68.0%) tested positive for HPV, with the majority of these [1,181/1,830 (64.5%)] having high-risk (HR) HPV infection; 37.4% were positive for HPV-16 (n = 684) and 5.1% for HPV-18 (n = 93). HPV type-specific prevalence was 48.1%, 65.9%, 81.3%, 92.2%, and 64.3% among cervical intraepithelial neoplasias (CIN) Grades I-III, squamous cell carcinomas (SCC) and adenocarcinoma (AC) cases, respectively. Most SCC cases (81.3%) had only one HPV genotype detected and almost a third (32.0%) of all cervical pathologies were HPV negative including 51.9% of CIN I (n = 283), 34.1% CIN II (n = 145), 18.7% of CIN III (n = 146), 7.8% of SCC (n = 5), and 35.7% of AC (n = 5) cases. This study provides important baseline data for monitoring the effect of HPV vaccination in NI and for comparison with other UK regions. The coverage of other HR-HPV genotypes apart from 16 and 18, including HPV-45, 31, 39, and 52, and the potential for cross protection, should be considered when considering future polyvalent vaccines.

    Full Text Available A review is presented on the pathogenesis of condiloma and cancer induced by papillomavirus infection: through minimal epithelial wounds these viruses reach basal cells; cell proliferation is activated in the healing process thereby allowing the viral replication cycle to take place. The product of viral gen E7 joins Rb cell protein releasing the factor (E2F that induces cell division. Proliferation should be opposed by apoptosis mediated by cell protein p53 but viral gen E6 inactivates the latter leading to an imbalance between cell division and death. With the occurrence of active, uncontrolled cell division the likelihood of malignancy development becomes high. Se revisa la patogénesis del condiloma y el cáncer inducidos por los papilomavirus (PVH, que puede resumirse así: a través de microheridas en el epitelio, el virus infecta las células basa les y en el proceso de cicatrización se activa la proliferación celular con lo que se permite iniciar el ciclo de replicación viral; el producto del gen viral E7 se une a la proteína celular Rb, liberando el factor E2F que induce a la célula a entrar en el ciclo de división. El estado proliferativo debería ser contrarrestado por una respuesta apoptótica que es mediada, en este tipo de células, por la proteína p53. El gen viral E6 inactiva esta proteína con lo que se permite la aparición del condiloma por desequilibrio entre la proliferación y la apoptosis. En el contexto de una replicación celular activa e incontrolada y con la proteína p53 inactivada para cumplir sus funciones proapoptóticas y reparadoras, es muy alta la probabilidad de aparición de una célula maligna. Este panorama se hace más complejo cuando los virus, eventualmente, se integran al genoma celular (10 que es más frecuente en el PVH tipo 18. En este caso el gen regulador E2 se inactiva y consecuentemente aumentan las proteínas E6 y E7.

    Full Text Available Background Ca cervix is the most common cancer among women in developing countries. In developed countries , screening is done by Pap smear which is resulting in drastic decrease in ca cervix which is not so in developing countries due to various reasons. So visual inspection of cervix can be cost effective screening procedure if its efficacy is proved in low resource countries. OBJECTIVE : To determine which screening method is efficient in detecting premalignant & malignant lesions of ca cervix in resource poor settings . METHODS : Pap smear was done in all 600 women , along with this VIA in 200 women , VILI in 20 0 women was done. Either pap or VIA or VILI positive cases were selected for colposcopy followed by biopsy if positive findings were there on colposcopy . 10% of either screening negative cases were subjected for biopsy to know false negative rate from each group. Main outcome measures: comparison of all three screening methods (pap smear , VIA , VILI in terms of sensitivity , specificity , PPV , NPV in comparison with gold standard colposcopic guided cervical biopsy . RESULTS: The aided visual inspection has mor e PPV than pap smear , The sensitivity of all three screening methods were comparable. The specificity & NPV of pap smear were high. CONCLUSION: So the aided visual inspection can be used as screening method in detection of premalignant and malignant lesion s of cervix in place of papsmear especially in rural setting.

    Quantitative analysis of protein phosphorylation provides important insights into molecular signaling mechanisms and a better understanding of many cellular processes. In this study, we coupled stable isotope dimethyl labeling with immobilized metal affinity chromatography (IMAC) enrichment to quantify protein phosphorylation at MS-determined phosphorylation sites. The proposed method was first characterized using alpha- and beta-casein as two model phosphoproteins, and further applied to the analysis of pregnant rat uteri with and without treatment with 8-bromo-cGMP. Dimethyl labeling has several significant advantages: global, fast (within 5 min) and complete (near 100%). Our results indicate that the labeling has no adverse effect on the IMAC enrichment for tryptic peptides having single and multiple phosphorylation sites. Moreover, the enhanced a1 signal and the complete reaction by dimethyl labeling provide unequivocal identification of both the N-terminal amino acid and the number of the labeling site. Using these two criteria in data validation, which is particularly important for identifying phosphoproteins, we found that the confidence in interpreting dimethyl-labeled peptides had greatly increased. In the analysis of late gestation rat uteri, the abundance ratio between treated and un-treated phosphopeptide signals ranged from 0.51 to 1.69 with an average of around 1.01 +/- 0.25. The obtained ratio of the phosphorylation levels at Ser 15 of HSP27 was further confirmed by the consistent results obtained from Western blot analyses. Based on the analysis of the results, it is interesting to note that the activated cGMP dependent protein kinase G (PKG) seems to affect the phosphorylation of proteins associated with the inhibition of cell migration and proliferation, redistribution of actin-associated proteins, and the increase of protein synthesis in late-gestation uteri. These observations provide important evidence suggesting that activated PKG may play a

    International Nuclear Information System (INIS)

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

    Full Text Available Ca.cervix and ca.breast are the most common life threatening cancers among women worldwide and the same is true for north east region of India also. So these two cancers remain a serious public health problem worldwide. Therefore more research work on the risk factors for ca.cervix and ca.breast is needed to better understand its etiology and pathogenesis. With this background this study is conducted to observe the possible factors such as socio-economic, marital etc., which may lead to the occurrence of these cancers in our region. For conducting this study we collect data by interviewing the patient registered in the B. Barooah cancer research institute which is the main sources of cancer data in Assam. Here we take 30 diagnosed cases each for ca.cervix and ca.breast and plot the data in a cross tabular form and analyze different factors and finally we try to abstract the conclusion from these tables. From the study it is revealed that there is strong evidence between the cancer type (ca.breast and ca.cervix and the following risk factors: family income (p=.017, age at marriage (p=.031, age of the patients (p=.017, number of children (p=.001, age at first child birth (p=.003, oral contraceptive used (p=.028. It has been further observed that most of the patients are house wives and non vegetarian. Moreover it is seen that of the two types of cancer the Bengali population of the state are more afflicted by ca.breast whereas the Assamese population are more afflicted by ca.cervix.

    In this review, we assessed the feasibility of total laparoscopic hysterectomy (TLH) in cases of very large uteri weighting more than 500 grams. We compared surgical outcomes and short term follow-up in 149 patients with the uterus weighing less than 350 g (group A: 40-350 g) and 100 patients with the uterus weighing more than 500 g (group B: 500-1550 g). We discovered no statistical difference between the 2 groups in terms of intraoperative complications (group A: 0%; group B: 2%) and postoperative stay (group A: 3.05 +/- 1.89 days; group B: 3.2 +/- 1.28 days). There were statistically significant differences between the 2 groups in terms of operative time (group A: 101.3 +/- 34.3 min; group B: 149.1 +/- 57.2 min.; p <.0001) and postoperative hospital stay length (group A: 2.8 +/- 0.7 days; group B: 3.5 +/- 1.7 days; p <.0001). No major complications occurred in either group. Postoperative minor complications were more frequent in group B (group A: 8.7%; group B: 18%; p = .03). Median time to well-being was comparable in both groups. In conclusion, TLH is a feasible surgical technique also in cases of very large uteri. An increase in operative time, intraoperative blood loss, hospital stay length, and postoperative minor complications can be expected as the uterine weight increases. PMID:17848315

  20. Estrogen influences dolichyl phosphate distribution among glycolipid pools in mouse uteri

    International Nuclear Information System (INIS)

    To determine the role that dolichyl phosphate availability plays in this induction, the authors studied the effects of estrogen priming on the content of dolichyl phosphate and the distribution of dolichyl phosphate among various glycolipids in uteri. Dolichol-linked saccharides were metabolically labeled to equilibrium with either [3H]glucosamine or [3H]mannose and extracted from primary explants of uterine tissue. The amount of dolichol-linked saccharide was calculated from the specific radioactivity determined for the corresponding sugar nucleotides extracted from the tissues. The major dolichol-linked saccharides identified were mannosylphosphoryldolichol (MPD), oligosaccharylpyrophosphorydolichol (OSL), and N,N'-diacetylchitobiosylpyrophosphoryldolichol (CBL). Estrogen increased the levels of MPD and OSL 4-fold; however, CBL levels did not change. After 3 days of treatment, the levels of these glycolipids were very similar to those in uteri from pregnant mice. The specific activity of GPD synthase was similar under all conditions studied. These studies provide the first determination of the levels of dolichol-linked saccharides in tissues and how these levels change during hormonal induction of glycoprotein assembly. Coupled with earlier studies, the present work demonstrates that among a number of key points of N-linked oligosaccharide assembly and transfer only synthesis of MPD increases coordinately with the increase observed in lipid- and protein-linked oligosaccharide assembly that occurs in vivo in response to estrogen. They suggest that control of MPD levels is an important regulatory aspect of N-linked glycoprotein assembly in this system

    Objective: The aim of the study was to investigate the cancer incidence and mortality in Huai'an area, China, from 2009 to 2011. Methods: The data about cancer incidence and mortality were provided by Huai'an Cancer Registry, China. Incidence and mortality rates, and standardized rates were calculated by age, gender, areas (urban and rural areas of Huai'an)and cancer sites. Results: The crude incidence rate for all cancer sites was 205.60/105 and the standardized incidence rate was 166.22/105. Both the crude and standardized rates were higher in urban area than in rural area for both sexes. The incidence rates increased in people aged 40 and over, and the peak ages of incidence were between 70-75 in both males and females. The crude mortality rate for all cancer sites was 153.88/105 and the standardized mortality rate was 122.14/105. Both the crude and standardized rates were similar in urban and rural areas for both men and women. The mortality rates were at low level under the age 50 in both sexes, but increased after the age 50, reaching the peak at the ages of 80-85 in both males and females. The top 10 most common cancer sites in rank were esophagus, stomach, lung, liver, colon-rectum, breast,pancreas, cervix uteri, brain and central nervous system, and leukemia, accounting for 87.56% of all cancers. The top 10 most leading causes of cancer death in order were cancers of esophagus, lung, liver, stomach, colon-rectum, pancreas, brain and central nervous system, leukemia, breast and lymphoma, accounting for 90.53% of all cancer deaths. Conclusion: Cancer is one kind of major diseases threatening people's health in Huai'an area, China. Cancer prevention and control should be enhanced, especially for esophageal cancer.

    Full Text Available Carcinoma of the uterine cervix is the most common gynecological malignancy in developing countries. However, its cutaneous metastasis is a rare entity. The reported incidence of cutaneous metastasis ranges from 0.1 to 2%. Frequent sites of cutaneous metastasis in decreasing order are: abdominal wall, vulva and anterior chest wall. To the best of our knowledge, only three cases of cutaneous metastasis to the upper extremity have been reported in the world. We report a case of a 74-year-old postmenopausal lady diagnosed to have carcinoma cervix (stage IIIB who presented with cutaneous metastasis to palm and thigh, 10 months after radical radiotherapy. At presentation, the primary disease had resolved completely. She had a small nodular growth in the left palm and left thigh. Fine needle aspirate cytology and core needle biopsy from both the nodular lesions were positive for squamous cell carcinoma.

    Full Text Available Primary adenocarcinoma of cervix constitute about 7-15% of all cervical cancer. Clear cell carcinoma, a form of cervical adenocarcinoma is a very rare tumor constituting only 4% of cervical carcinoma. Risk factor and pathogenesis of this disease are not exactly revealed. Intrauterine exposure to diethylstilbestrol and associated non-steroidal estrogen during pregnancy before 18 weeks is the only risk factor. Here we report an unusual case of clear cell carcinoma of cervix presented with bilateral pleural effusion, cytology of which shows adenocarcinoma. This is a rare case since patient had no history of diethylstilbestrol exposure and presented with bilateral pleural effusion. This is the first described case report of clear cell carcinoma of cervix with upfront malignant pleural effusion. [Int J Res Med Sci 2015; 3(7.000: 1795-1797

    An 18 year old single Jewish woman with the Waardenburg syndrome and absence of a vagina and right sided adnexa uteri is reported. Other congenital malformations associated with the Waardenburg syndrome are mentioned and it is postulated that they may be the result of an altered invasion of neurones or altered neurones in certain organ systems early in embryogenesis.

    Pyometra, which is accompanied by bacterial contamination of the uterus, is defined as a complex disease associated with the activation of several systems, including the immune system. The objective of the study was to evaluate the gene expression profile in dogs with pyometra compared with those that were clinically normal. The study included uteri from 43 mongrel bitches (23 with pyometra, 20 clinically healthy). RNA used for the microarray study was pooled to four separated vials for control and pyometra. A total of 17,138 different transcripts were analyzed on the uteri of female dogs with pyometra and of healthy controls. From 264 inflammatory response-related transcripts, we found 23 transcripts that revealed a 10- to 77-fold increased expression. Thereby, the expression of interleukin 8 (IL8), interleukin-1-beta (IL1B), interleukin 18 receptor (IL18RAP), interleukin 1-alpha (IL1A), interleukin receptor antagonist (IL1RN) and interleukin 6 (IL6) increased 77-, 20-, 17-, 13-, 13- and 11-fold, respectively. Furthermore, the expression of the calcium binding proteins S100A8 was 44-fold higher, and that of S100A12 and S100A9 37-fold, respectively, in the uteri of canines with pyometra compared with that of the controls. Moreover, the expression of the transcripts of toll-like receptors (TLR8 and TLR2), integrin beta 2 (ITGB2), chemokine ligand 3 (CCL3), semaphorin 7A (SEMA7A), CD14 and prostaglandin-endoperoxide synthase 2 (PTGS2) was increased between 10- and 18-fold. Furthermore, after using RT-qPCR we found an increased expression of AOAH, IL1A, IL8, CCL3, IL1RN and SERPINE 1 mRNAs which can be served also as markers of the occurrence of pyometra in domestic bitches. In summary, it is concluded that up-regulation of interleukins may be used as a marker of the inflammatory response in dogs with pyometra. Moreover, all of the 23 up-regulated transcripts may be novel molecular markers of the pathogenesis of canine pyometra. Several proteins--–products of these

    Background: In Brazil, cervical cancer is the second most common among women. Radiation therapy is part of its interdisciplinary management, playing an important role in their loco regional control. The major challenge of modern medicine in radiotherapy is to develop predictive methods that can determine the level of radiosensitivity of the patient and the healthy surrounding tissue in order to individualize the prescribed radiation dose, to prevent severe side effects and promoting better local tumor control. This study evaluated the acute and chronic adverse effects on the skin, lower gastrointestinal tract and urinary tract of radiotherapy in 47 cervical cancer patients. Methods and Materials: Biological material was collected and DNA from peripheral blood was extracted of ali patients studied. The fragments of TP53 and ATM were amplified to be sequenced, to verify if there are any polymorphisms witch could be responsible to the radiosensitivity of the patients. Results and Discussion: In a univariate analysis, the variable age was strongly associated with a risk of acute toxicity skin (p=O,023). Patients that received a high dose of external beam radiation and patients who have undergone brachytherapy, showed a significantly higher incidence of chronic urinary tract toxicity (p=O,031) and (p=O,019), respectively. The exchange G>A in the position 5557 of the A TM gene was significantly associated with the risk of acute lower gastrointestinal tract (p=O,008). There wasn't association between the other TP53 polymorphisms analyzed and the frequency of side effects (p>O,05). Our data revealed that patients who evolved significant association presented death (p=O,019) with the increase of chronic skin radiossensitivity. Conclusions: These observations corroborate the importance of investigating the genetic profile to predict adverse side effects in cervical cancer patients undergoing radiotherapy. These genes have an important role in DNA repair pathways and

    Full Text Available Background: Cervical cancer is the most common cancer in Indian women and is a preventable cancer. Pap smear being an expensive screening test, increased emphasis is being laid on the development of a reliable and cost effective screening method for cervical cancer. This study aims at early detection of cervical dysplastic lesions using a simple and cost-effective screening test like visual inspection of cervix with 3% acetic acid (VIA and comparing its diagnostic efficacy with the more expensive Pap screening by Bethesda method. Methods: Ours was a prospective study carried out on a 100 sexually active women aged 25-50 years, coming to our OPD. The women were subjected to both a VIA and Pap smear. All Pap and VIA positive women were subjected to a cervical biopsy, whose histopathological report was taken as the gold standard. Results: In our study the sensitivity of VIA was more than that of cytology (100% versus 66.67% but the specificity was significantly lesser (47.83% compared to the 73.91%. The negative predictive value of VIA was comparable with Pap smear (100% and 85% respectively as was the positive predictive value (42.86% and 50%. However the diagnostic accuracy of VIA was lower than that of Pap smear (66.67% and 81.25% in our study. Conclusions: In this study VIA was found to have efficacy comparable to Pap smear in screening cervical cancer. Thus we recommend that VIA could be used as an alternative screening tool to detect early cervical dysplasia - especially in poor resource settings.

    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 objective is to compare the prognosis value of the pre-therapy pelvis PET--T.D.M. with {sup 18}F-F.D.G. and MRI in the uterine cervix carcinoma. The conclusions: in the uterine cervix carcinomas, the existence of a pelvis ganglion injury on the pre-therapy PET-T.D.M. with {sup 18}F-F.D.G. is a prognosis factor independent of recurrence and death at one year. The MRI does not bring any additional information relative to the prognosis of the disease. (N.C.)

  14. Progress in Diagnosis and Treatment of Small Cell Carcinoma of the Cervix

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Small cell carcinoma of the cervix (SCCC) belongs to the neuroendocrine carcinomas, and it is a rare gynecological tumor of high-potential malignancy. It has a poorer prognosis compared to cervical squamous cancer or adenocarcinoma, and the therapeutic regimen of the disease differs. Diagnosis is based on pathomorphological characteristics, i.e., the small and round cancer cells (oat cell) which are uniform in shape and size, with the immunohistochemical marker helpful for diagnosis. Combined therapy is first recommended. Postoperative chemotherapy with platinum/etoposide (PE), vincristine/adriamycin/cyclophosphamide (VAC) and taxel/carboplatin (TP) can markedly improve the prognosis of early SCCC patients.

    In vivo Raman spectroscopy is being projected as a new, noninvasive method for cervical cancer diagnosis. In most of the reported studies, normal areas in the cancerous cervix were used as control. However, in the Indian subcontinent, the majority of cervical cancers are detected at advanced stages, leaving no normal sites for acquiring control spectra. Moreover, vagina and ectocervix are reported to have similar biochemical composition. Thus, in the present study, we have evaluated the feasibility of classifying normal and cancerous conditions in the Indian population and we have also explored the utility of the vagina as an internal control. A total of 228 normal and 181 tumor in vivo Raman spectra were acquired from 93 subjects under clinical supervision. The spectral features in normal conditions suggest the presence of collagen, while DNA and noncollagenous proteins were abundant in tumors. Principal-component linear discriminant analysis (PC-LDA) yielded 97% classification efficiency between normal and tumor groups. An analysis of a normal cervix and vaginal controls of cancerous and noncancerous subjects suggests similar spectral features between these groups. PC-LDA of tumor, normal cervix, and vaginal controls further support the utility of the vagina as an internal control. Overall, findings of the study corroborate with earlier studies and facilitate objective, noninvasive, and rapid Raman spectroscopic-based screening/diagnosis of cervical cancers.

  17. Carcinoma of the cervix. Correlations between MR staging and prognosis

    International Nuclear Information System (INIS)

    In 110 patients with cervical cancer, correlations between pretreatment MR findings and 5-year prognoses were analyzed. MR findings were classified according to clinical staging criteria of the Japan Society of Obstetrics and Gynecology. In 75 patients, staging by MR and that by conventional clinical methods agreed with surgical findings in 51 (68%) cases each, was overestimated in 5 (7%) and 16 (21%), and underestimated in 19 (25%) and 8 (11%), respectively. None of 41 patients without high-intensity areas (HIA) in the cervix on MR developed recurrence, but 26 of 69 (38%) with HIA relapsed. Two of 67 (3%) patients with MR stage IIa or lower developed recurrence, but 24 of 43 (56%) with stage IIb or higher relapsed. Among 26 patients with poor prognoses, 2 of 11 (18%) with stage IIb or lower, versus 9 of 15 (60%) with stage IIIb or higher disease detected by MR had distant metastases. Among 22 patients with MR stage IIb disease, local and distant recurrence occurred in 6 and 2 (50%, 17%) of 12 patients who underwent radical hysterectomy, versus 1 and none (10%, 0%) of 10 who received definitive radiotherapy. Fifteen of 95 (16%) patients without lymph node swelling greater that 1.5 cm on MR developed recurrence, while 11 of 15 (73%) patients with lymphadenopathy relapsed. MR is valuable not only in staging cervical cancer but also in assessing the risk of recurrence. (author)

    We report a rare case of extranodal NK/T-cell lymphoma, nasal type of the uterine cervix that showed cytologic features mimicking cervical cancer. A 65-year-old woman presented with vaginal bleeding. Gynecological examination revealed a bulky tumor of the cervix. A conventional Papanicolaou-stained cervical smear showed hypercellularity consisting of numerous variably sized cohesive clusters that mimicked epithelial tumors, with a necrotic and inflammatory background. A small number of individually scattered cells were also identified. These scattered cells showed pleomorphic, often cleaved, or horseshoe-shaped nuclei and pale cytoplasm. Biopsy specimens revealed a diffuse growth of atypical cells with an angiocentric pattern. Extensive necrosis and infiltration of inflammatory cells were present. There were numerous mitotic figures. The tumor cells were positive for CD45RO, CD3ε, CD56, granzyme B, TIA-1, CD7, and Epstein-Barr virus (EBV)-encoded small RNA (EBER) by in situ hybridization, and negative for cytokeratin, chromogranin A, synaptophysin, CD4, CD5, CD8, CD20, and CD30. Based on these findings, this tumor was diagnosed as extranodal NK/T-cell lymphoma, nasal type of the uterine cervix. Diagn. Cytopathol. 2016;44:430-433. © 2016 Wiley Periodicals, Inc. PMID:26872300

    Objective: To determine the impact of antisense oligonucleotides targeting vascular endothelial growth factor (VEGF) on radiosensitivity of uterine cervix cancer Hela cells. Methods: VEGF antisense oligodeoxynucleotides (ASODN) was transfected into Hela cells by liposome-mediated method. Cells transfected with the oligodeoxynuclecotide and saline were used as control groups. Cells were irradiated by 6 MV X ray at the dose of 0 Gy, 2 Gy, 4 Gy and 6 Gy respectively. The expression of VEGF mRNA was determined by RT-PCR. Apoptosis were evaluated using FCM. Cloning efficiency was deter-mined by colony formation assay. Results: The expression of VEGF mRNA was inhibited by ASODN (P < 0.01) in Hela cells. The inhibited activation which was influenced by radiation resulted in increasing apoptosis (P < 0.01) and inhibiting plating efficiency (P < 0.01). Conclusion: The expression of VEGF induced by Ⅹ irradiation in Hela cells can be blocked by VEGF ASODN. Treatment with VEGF might increase apoptosis in HeLa cells and enhance radiosensitivity.

    Experimental infection models for Ascaridia galli rely on the use of eggs isolated either directly from worm uteri or from host faeces. We investigated whether A. galli eggs isolated from the two sources differ in their embryonation ability. A. galli eggs originating from 12 worm infrapopulations were isolated both from faeces of the living host (faecal eggs) and directly from worm uteri after host necropsy (uterine eggs). The isolated eggs from each infrapopulation and source were incubated in Petri dishes (n=24) containing a potassium-dichromate (0.1%) medium for 28 days (d) at room temperature. Starting from the day of egg isolation (d0), in ovo larval development was evaluated every second day by examining morphological characteristics of 200 eggs/petri dish. A total of 72,000 eggs were classified into undeveloped, early development, vermiform or fully embryonated stages. Isolation procedures caused similar damage to uterine and faecal eggs (2.2% and 0.5%, respectively; P=0.180). The first sign of in ovo embryonic development in faecal eggs (7%) was observed during the 24-h period when faeces were collected. On d28, a higher percentage of uterine eggs remained undeveloped when compared with faecal eggs (58.6% vs 11.0%; P<0.001). Although a higher (P<0.001) percentage of faecal eggs entered both the early developmental and vermiform stages, which took place primarily within the first two weeks of incubation, there was no time-shift between the development of faecal and uterine eggs. Starting from day 10, higher (P<0.05) percentages of faecal eggs completed embryonation compared with uterine equivalents. Eggs from both sources reached a plateau of embryonation by the end of 2nd week of incubation, with faecal eggs having a greater than two-fold higher embryonation ability. Cumulative mortality was higher in uterine eggs (14.3%) than in faecal eggs (0.2%). We conclude that faecal eggs have a higher embryonation ability than uterine eggs possibly due to maturation

    The first case of benign lentigo of the uterine cervix is reported, providing further evidence that the cervix is able to form the entire spectrum of melanocytic lesions known to occur in the skin. Review of the literature reveals 19 cases of primary malignant melanoma of the cervix and 30 cases of blue nevus. The reported case offers support that benign lentigines may play a role as premalignant lesions of malignant melanoma not only in the skin, but aldo in mucous membranes. PMID:7327080

    The uterine cervix plays an important role in the natural fertilization process and, consequently, it is also a significant factor in infertility. In about 6% of infertile couples, the infertility is caused by the cervical factor. The post coital test (PCT) is the most essential diagnostic procedure. A good PCT result excludes the cervical factor as the cause of infertility. A poor or negative PCT result, on the other hand, only indicates that the cervical tract is the cause in the case of women with verified ovulation and in whom other causes have been excluded. Treatment of the cervical factor has always been difficult. Intrauterine insemination is the best documented treatment method with a pregnancy rate of about 30%. In future, gamete intrafallopian transfer (GIFT) and in vitro fertilization (IVF) may be alternatives in the treatment of infertility owing to the cervical factor. PMID:2184560

In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall. PMID:17898820

  7. Subclinical human papillomavirus infection of the cervix

    International Nuclear Information System (INIS)

    A prospective study to investigate a group of Iraqi woman with proved genital vulval warts, to seek evidence of human papillomavirus infection in apparently normal looking cervixes and to investigate the natural history of infection. From December 1997 to August 1998, 20 women with vulval warts were enrolled along with 20 aged-matched control cases without warts. Their ages ranged between 19-48 years with a mean of 30.4 years, (+/- standard deviation = 2.3) for patients and 18-48 years with a mean of 29.7 (+/- standard deviation = 2.7) for the control group. General and gynecological examinations were carried out. Cervical swabs for associated genital infection, papilloma smears, speculoscopy and directed punch biopsies were carried out to detect subclinical human papillomavirus infections of the cervix and associated intraepithelial neoplasm. Cytology results showed that 11 (55%) of patients had evidence of cervical infection by human papillomavirus, 6 (30%) showed mild dysplastic changes, 3 (15%) showed moderate dysplastic changes, whilst 2 (10%) showed no dysplastic changes. Speculoscopy and acetowhitening was positive in 11 (55%) and collated histological results showed evidence of human papillomavirus infection in 9 patients (45%). As for the control group one case (5%) had evidence of human papillomavirus infection. Subclinical human papillomavirus infection is more common than was previously thought among Iraqi women. It may appear alone or in association with vulval or exophytic cervical warts, or both, and may be more common than the clinically obvious disease. Speculoscopy as an adjunctive method to colposcopy was found to be a simple and an easy to perform technique. Its combination with cytology gave relatively good results when it was used as a triage instrument, and may have a more promising performance in the future. (author)

  9. Local therapy for small cell carcinoma of the cervix

    International Nuclear Information System (INIS)

    Objective: Small cell carcinoma of the uterine cervix is a rare and aggressive tumor. This tumor is similar to small cell carcinoma of the lung with a tendency to metastasize early. While there has been an increasing interest in the use of chemotherapy regimens similar to those used for small cell carcinoma of the lung, the optimum local therapy for small cell carcinoma of the cervix remains unknown. We reviewed the treatment outcome of patients with small cell carcinoma of the cervix diagnosed in our cancer center with an emphasis on the local/regional disease control. Material and Methods: Between 1983 and 1993, medical records of patients diagnosed with carcinoma of the uterine cervix were reviewed. There were 281 patients with carcinoma of the uterine cervix referred to our department for radiation treatment. Seven patients had pathologic diagnosis of either small cell or neuroendocrine histology. Details of the treatments and follow-up information of these patients were reviewed with a medium follow-up period of three years (range - 1 to 4 years). Results: Five patients had pure small cell histology. Two patients had mixed histology: one with mixed small cell anaplastic neuroendocrine cells and a small foci of adenocarcinoma, the other had mixed small cell and squamous cell histology. Four patients had clinical stage IB disease. The others had IIA, IIB, and IIIB disease, respectively. All patients received either irradiation (XRT) alone or as part of the local therapy. Three patients received XRT alone, one received surgery followed by XRT, one received XRT followed by surgery, and the remaining two had triple modality treatment (chemotherapy, surgery, and XRT). Three patients were alive without evidence of disease recurrence at the last follow-up. Two of these received adjuvant chemotherapy in addition to local therapy. The third patient, whose tumor was smaller than one cm at the time of diagnosis, received XRT alone. Four patients died with disease

    Six patients with carcinoma of the vulva and 3 with carcinoma of the vagina following radiation therapy for cancer of the cervix were analyzed. The interval between irradiation and diagnosis of the second tumor varied from 5 to 23 years. Despite the lack of having detailed information on irradiation factors in all patients, circumstantial evidence from this study suggests that radiation therapy may have contributed to the development of carcinoma of the vulva and vagina in some of the patients. Close follow-up patients treated for squamous carcinoma of the genital tract must emphasize inspection for new lesions. The incidences previously reported in the literature are also reviewed for comparison. (author)

    2014-01-01

    Full Text Available The connection between human papillomavirus (HPV infection and the consequent sequelae which establishes cervical neoplastic transformation and invasive cervical cancer has redefined many aspects of cervical cancer research. However there is still much that we do not know. In particular, the impact of external factors, like seminal fluid in sexually active women, on pathways that regulate cervical inflammation and tumorigenesis, have yet to be fully understood. HPV infection is regarded as the initiating noninflammatory cause of the disease; however emerging evidence points to resident HPV infections as drivers of inflammatory pathways that play important roles in tumorigenesis as well as in the susceptibility to other infections such as human immunodeficiency virus (HIV infection. Moreover there is emerging evidence to support a role for seminal fluid, in particular, the inflammatory bioactive lipids, and prostaglandins which are present in vast quantities in seminal fluid in regulating pathways that can exacerbate inflammation of the cervix, speed up tumorigenesis, and enhance susceptibility to HIV infection. This review will highlight some of our current knowledge of the role of seminal fluid as a potent driver of inflammatory and tumorigenic pathways in the cervix and will provide some evidence to propose a role for seminal plasma prostaglandins in HIV infection and AIDS-related cancer.

    2012-06-01

    Full Text Available O trabalho discute a emergência da categoria profissional dos citotécnicos no Brasil e sua trajetória entre a década de 1970 e o final dos anos 1990. No início desse período, a Organização Pan-americana de Saúde passou a considerar o câncer do colo do útero como um grave problema de saúde pública, passível de ser controlado nos países em desenvolvimento. Nesse contexto, surgem as primeiras campanhas de rastreamento da doença no país. A institucionalização dessas campanhas transformou os citotécnicos em elementos indispensáveis para a viabilização do controle da doença. Com a expansão da demanda por sua atividade e o surgimento das primeiras iniciativas para sua formação, novas questões começam a surgir. Como formar, em quantidade e qualidade adequadas, esses novos profissionais? Qual a grade curricular adequada às suas tarefas e responsabilidades? Como monitorar o funcionamento dos cursos? No campo da normatização da nova atividade, outras questões se apresentam: como garantir o monopólio sobre a atividade exercida, como caracterizar sua especificidade, qual a formação exigida aos que vão exercê-la? Tais pontos passam a ser temas de embates e negociações, num típico processo de consolidação de uma nova profissão. O processo de institucionalização do programa de prevenção do câncer do colo do útero e a consequente necessidade de garantia de qualidade dos exames executados fizeram com que essas questões voltassem ao centro das atenções. Este estudo visa a contribuir para a ampliação do conhecimento sobre a formação do citotécnico, e em âmbito mais geral, ao processo de formação profissional em saúde no Brasil.The paper discusses the emergence of the professional category of cytotechnologists in Brazil and its history from the 1970s and late 1990s.

    Full Text Available OBJECTIVE: Is Trichomonas vaginalis (TV an inducing factor for the development of (pre-cancerous lesions of the cervix? DESIGN: Cross sectional study. SETTING: Screening healthy Belgian women with low infection risk. SAMPLE: 63,251 consecutive liquid based cervical samples. METHODS: Real time quantitative PCR for presence of TV, 18 HPV types and Pap smear analysis of cytologic abnormalities. MAIN OUTCOME MEASURES: Association of TV and HPV with cervix dysplasia. RESULTS: The overall prevalence of TV DNA was 0.37%, of low risk HPV 2%, of high risk HPV 13.2%, and 8.8 % had cytological abnormalities. Both LR-HPV and HR-HPV were significantly associated with all cytological abnormalities. Presence of TV was associated with LR- and HR-HPV, ASC-US and HSIL, but not with other abnormalities. All women with TV and HSIL also had HR-HPV, while the latter was present in only 59% of women with TV and ASC-US. Amongst HPV negative women, TV was found in 1.3% of women with ASC-US, but only in 0.03% of women with normal cytology (OR 4.2, CL95% 2.1-8.6. In HR-HPV positive women, presence of TV increased the likelihood of cytological abnormalities somewhat (P=0.05, mainly due to an increase in ASC-US and LSIL, but not HSIL. CONCLUSIONS: We conclude that TV infection is associated with both LR and HR-HPV infection of the cervix, as well as with ASC-US and HSIL. TV is a concomitant STI, but is not thought to be a co-factor in the causation of HSIL and cervical cancer. However, TV may cause false positive diagnoses of ASC-US.

  19. Genistein-induced fluid accumulation in ovariectomised rats' uteri is associated with increased cystic fibrosis transmembrane regulator expression

    2014-02-01

    Full Text Available OBJECTIVE: High genistein doses have been reported to induce fluid accumulation in the uteri of ovariectomised rats, although the mechanism underlying this effect remains unknown. Because genistein binds to the oestrogen receptor and the cystic fibrosis transmembrane regulator mediates uterine fluid secretion, we hypothesised that this genistein effect involves both the oestrogen receptor and cystic fibrosis transmembrane regulator. METHODS: Ovariectomised adult female Sprague-Dawley rats were treated with 25, 50, or 100 mg/kg/day genistein for three consecutive days with and without the ER antagonist ICI 182780. One day after the final drug injection, the animals were humanely sacrificed, and the uteri were removed for histology and cystic fibrosis transmembrane regulator mRNA and protein expression analysis using real-time polymerase chain reaction and Western blotting, respectively. The cystic fibrosis transmembrane regulator protein distribution was analysed visually by immunohistochemistry. RESULTS: The histological analysis revealed an increase in the circumference of the uterine lumen with increasing doses of genistein, which was suggestive of fluid accumulation. Moreover, genistein stimulated a dose-dependent increase in the expression of cystic fibrosis transmembrane regulator protein and mRNA, and high-intensity cystic fibrosis transmembrane regulator immunostaining was observed at the apical membrane of the luminal epithelium following 50 and 100 mg/kg/day genistein treatment. The genistein-induced increase in uterine luminal circumference and cystic fibrosis transmembrane regulator expression was antagonised by treatment with ICI 182780. CONCLUSION: Genistein-induced luminal fluid accumulation in ovariectomised rats' uteri involves the oestrogen receptor and up-regulation of cystic fibrosis transmembrane regulator expression, and these findings reveal the mechanism underlying the effect of this compound on changes in fluid volume in

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

  2. Persisting cyclical uterine bleeding in patients treated with radical radiation therapy and hormonal replacement for carcinoma of the cervix

    International Nuclear Information System (INIS)

    Radical radiation therapy used for carcinoma of the cervix will ablate ovarian function. Since January 1986, our policy has been to administer oral combination oestrogen-progesterone replacement hormonal therapy to all premenopausal patients undergoing radical radiation with or without synchronous chemotherapy, for invasive cervix cancer. Five out of 22 (23%) such patients unexpectedly experienced between one and four episodes of cyclical per vaginal bleeding after the completion of radiation therapy. Bleeding episodes occurred in the absence of persistent tumor or radiation reaction, and suggest persisting endometrial response to exogenous hormonal stimulation. Uterine activity was temporarily retained in these five patients despite a minimal endometrial surface dose of between 4800 and 6490 cGy. The limited number of cycles before bleeding spontaneously ceased may represent the slow death of endometrial cells subsequent to radiation or radiochemotherapy treatment, and has not previously been described. In view of the paucity of data on the radiosensitivity of normal endometrium, we have carefully examined these patients who appear to have retained endometrial sensitivity to hormonal stimuli after radical radiation-chemotherapy for uterine cervix cancer

    Full Text Available Postmenopausal bleeding (PMB is a discharge that occurs following the firm diagnosis of menopause, which is at least six months from the end of women’s menstrual cycle but not to be confused with infrequent or irregular periods occurring around the time of menopause. It is a common problem representing 5% of all gynecology outpatient attendances which are to eliminate endometrial cancer as the cause of bleed and PMB should be reported urgently to the gynecologist. Uterine bleeding in postmenopausal women is highly indicative clinically of malignancy originating from cervix or endometrium and Human papilloma virus (HPV is one of the causative agent for carcinoma cervix. Incidence of carcinoma cervix increases with the age in mature women, however, incidence of human papillomavirus (HPV infection reduces as menopause sets in. The presence of the virus could be used as an early indication of disease potential. Because the Pap test can only detect clinical evidence of cervical disease, molecular-based diagnostic tools are being used more frequently to detect the virus before abnormal cell growth can be observed. This study was aimed to determine the status of cervical cancer and HPV 16 DNA positivity in relation to postmenopausal bleeding.

OBJECTIVE: To compare sensitivity and specificity of two methods for screening of bad cervix and to know IDR (increase detection rate of cervical cancer by conventional Pap smear and liquid based cytology. MATERIAL AND METHOD: 200 women attending Gynaecology OPD were random selection on the basis of inclusion criteria. All 200 selected women were subjected for down staging through per speculum examination for identification of bad cervix. Pap smears of all 200 selected women were taken and ensured that no local douche, antiseptic cream and no local internal examination was done on the day of test. The prepared smears were then stained according to Papanicolaou's technique. Liquid based cytology smears preparing by using cervical brush 1-1.5cm were inserted into the cervical os until the large outer bristles of the brush touch ectocervix. Data collected for sociodemographic, parity, down staging clinical examination Pap smear and LBC was organised, interpreted and analysis on appropriate statistical software. P value < 0.05 is considered significant RESULT: Analysis revealed that the maximum number of women in our study are from middle age group(31-40yrs, low socioeconomic status, married before 18 yrs, multipara, do not use any contraceptive, uneducated, urban, Muslim population.in this study more abnormal smear is seen in LBC as compared to pap smear. Sensitivity and specificity for LBC is more as compare to pap smear. CONCLUSION: In low resource setting like ours were facilities for radiology, chemo- radiotherapy and supportive care are limited or unavailable. It is important to identify which resources fill healthcare need most effectively and to consider alternative approaches, LBC is strongly advocated in the best interest of public health, by improving the quality of the sample and reducing the

After 4000 to 4500 rads to pelvis by external radio-therapy, patient was assessed for intra cavitary application. Total given dose to point A was 7500 rads, to point B was 5000 rads. If patient was not suitable a split course was given where patient was asked to come after 3 weeks for intracavitary application. A comparative study of both methods was done. There was significant improvement in the control of central disease by applying intracavitary source. Radiation reactions were comparable. (author). 4 tables, 10 refs

    Full Text Available Metastases to gastrointestinal tract are uncommon. In particular, metastases to the ampulla of Vater are very rare and may represent a significant diagnostic challenge. Metastases from the uterine cervix to the ampulla of Vater are exceedingly rare and only one case has been described in the available literature. We describe here a second case of metastatic squamous cell carcinoma of the cervix to the ampulla of Vater in a 45-year-old woman. Poorly differentiated squamous cell carcinoma presented as an isolated metastasis to the ampulla of Vater, two years after the initial diagnosis. While the squamous cell carcinoma could occur as primary ampullary carcinoma, albeit very rare, it is necessary to exclude the possibility of metastatic cancer.

  7. Locally advanced cervix carcinoma - innovation in combined modality therapy

    International Nuclear Information System (INIS)

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

  8. Expression of LIF, VEGF,CD57 and CD68 after the transfer of rat embryos to mouse uteri

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    The high failure rate of interspecific pregnancy is a major obstacle to the successful interspecific cloning of mammals. To investigate the reasons for the failure of interspecfic pregnancy between rats and mice, we transferred rat blastocysts into mouse uteri on the third day of pseudopregnancy (D3). Our previous study showed that intact rat embryos could still be observed in mouse uteri on D9. In the present study, we found that expression of CD57 and CD68 increased significantly at the maternal-fetal interface following the transfer of rat embryos. Similarly, Leukaemia inhibitory factor (LIF) expression increased, but vascular endothelial growth factor (VEGF) expession decreased. In a co-culture system, the percentage of rat ectoplacental cones (EPCs) with adhesion and outgrowth and outgrowth area on mouse uterine decidual cells were less than that of mouse EPCs. These results indicate that an increase in the immunological rejection response and a decrease in the invasiveness of rat embryos may be important reasons for the failure of interspecific pregnancy between rat and mouse.

  10. Concomitant chemobrachyradiotherapy with ifosfamide and cisplatin followed by consolidation chemotherapy in locally advanced squamous cell carcinoma of the uterine cervix: Results of a phase II study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the efficacy and toxicity of ifosfamide and cisplatin administered concomitantly with low-dose-rate brachytherapy followed by consolidation chemotherapy in the treatment of locally advanced squamous cell cervical carcinoma (LASCC). Methods and materials: Forty-four patients with biopsy-proven LASCC were enrolled. FIGO Stages IB2 bulky to IVA were entered into this study. Patients were assigned to receive external radiotherapy (50 Gy in 25 fractions); then ifosfamide 2 g/m2 plus cisplatin 75 mg/m2 was applied during two low-dose-rate brachytherapy applications, and 4 cycles of consolidation chemotherapy with the same drug combination were given after completion of radiotherapy. The planned dose to point A was 85 Gy. Results: All patients received both courses of concomitant chemobrachytherapy and at least 1 cycle of consolidation chemotherapy. The average duration of radiation was 45.1 days. The clinical complete response rate was 100%. Grade 3 and 4 leukopenia occurred in 25% and 11% of the cycles, respectively. After a median follow-up of 34 months (range, 20-54 months), the recurrence-free and the overall survival rates were 84% and 91%, respectively. Major delayed local complications occurred in 7 cases (16%). Conclusions: These results indicate that concomitant chemobrachyradiotherapy with ifosfamide and cisplatin is a feasible combination for patients with LASCC of the cervix uteri. A randomized trial is planned

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

    To report 5-year outcomes of a prospective registry study investigating posttherapy FDG PET/CT in women with locally advanced cervical cancer. A secondary analysis assessing the prognostic significance of HPV infection was performed. Patients underwent definitive chemoradiation followed by a single FDG PET/CT scan for response assessment. A complete metabolic response (CMR) was defined as no evidence of FDG-avid disease. Patients were dichotomized according to HPV infection status into a 'higher-risk' group and a 'lower-risk' group, with the higher-risk group comprising those with alpha-7 strain HPV (subtypes 18, 39 and 45) and those who were HPV-negative and the lower-risk group comprising those with alpha-9 strain HPV (subtypes 16, 31, 33, 52 and 58) and those with mixed strains. Survival outcomes, patterns of failure and salvage therapy outcomes were investigated for their association with metabolic response and HPV status. In 105 patients the median prospective follow-up was 5.2 years. The 5-year cancer-specific, overall and progression-free survival rates in patients with a CMR were 97 %, 93 % and 86 %, respectively. In patients without a CMR, the corresponding 5-year survival rates were 36 %, 22 % and 0 % respectively (p < 0.01). PET response was associated with patterns of failure (p < 0.01), with the 5-year freedom from local, nodal and distant failure in patients with a CMR being 94 %, 90 % and 94 %, respectively. Of 16 patients who underwent salvage therapy, 12 had disease detected on the surveillance PET scan, and 8 achieved a post-salvage CMR of whom all were alive at a median of 4.9 years. DNA adequate for HPV analysis was extracted in 68 patients. The likelihood of a PET metabolic response was not influenced by HPV infection status, with 71 % and 75 % of higher-risk and lower-risk patients, respectively, achieving CMR (p = 0.83). Higher-risk patients had a poorer OS (HR 2.6, range 1.0 - 6.6, p = 0.05) in univariable analysis but

    We performed a case control study to determine factors which influence the development of cervical carcinoma. Factors like reproduction, sexual behaviour and genital infections were considered. 309 patients with cervical intraepithelial neoplasia (CIN) or invasive cervical carcinoma were interviewed as a study group. 490 patients with no cervical changes served as control group. The two groups of patients had a different age distribution with an early age summit in the study group. No differences were observed in relation to residence areas and attendance of screening for cervical carcinoma. 83.5% of the women in the study group (n = 258) and 81.0% (n = 397) of the control group attended the screening for cervical carcinoma. According to our observation, the following factors increased the risk of CIN or invasive cervical carcinoma: early menarche ( 14 years), multiparity (0 vs 1-3 vs > 4), first pregnancy before the age of 20, divorced women, early sexual contact ( 21 years), multiple sexual partners, vaginal discharge and venereal diseases (gonorrhea, syphilis). Factors like reproductive characteristics and genital infections can be interpreted as expressions of sexual behaviour. Despite the improving social status, increasing health consciousness and extensive mass-screening for cervical cancer, the above mentioned risk factors still play an important role. Risk group should be followed and examined strictly so as to reduce the rate of invasive cervical carcinoma in screened patients. PMID:8048284

  15. Risk factors of distant metastasis in patients with squamous cell carcinoma of the uterine cervix treated with postoperative irradiation

    International Nuclear Information System (INIS)

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

    Purpose. - In cervix carcinoma: (a) to evaluate the ability of ({sup 18}F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the lymph node detection; (b) to investigate the prognostic and predictive value of the primary cervical PET parameters. Patients and methods. - Ninety patients treated for cervix carcinoma and evaluated initially by MRI and FDG PET were included. The performances of FDG-PET for lymph node detection (relatively to the lymph node dissection) have been described (sensitivity, specificity, positive predictive value and negative predictive value). PET tumour parameters analyzed were: maximum standard uptake value (SUV{sub max}), the volume and the maximum diameter. The prognostic and predictive values of these parameters were investigated. The tumour response was evaluated on surgical specimens. Results. - PET detected the cervical tumour with a sensitivity of 97% (mean values: SUV{sub max} = 15.8, volume = 27 mm{sup 3}, maximum diameter = 47). For the detection of the lymph nodes, the values of sensibility, specificity, positive predictive value and negative predictive value were: 86, 56, 69 and 78% in the pelvic, and 90, 67, 50 and 95% for the para-aortic area, respectively. The SUV{sub max} was correlated with histologic response (P = 0.04). The frequency of partial histological response was significantly higher for tumour SUV{sub max}> 10.9 (P = 0.017). The maximum PET diameter and pathologic response had an impact on disease-free survival and overall survival in multivariate analysis (P < 0.05). Conclusion. - PET has high sensitivity in detecting pelvic and para-aortic lymph nodes. Some primary cervical tumour PET parameters are useful as prognostic and predictive factors. (authors)

    International Nuclear Information System (INIS)

    We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

  20. Evaluation of intra- and inter-fraction movement of the cervix during intensity modulated radiation therapy

    International Nuclear Information System (INIS)

    Background and purpose: To assess the degree of intra- and inter-fraction cervical motion throughout a course of intensity modulated radiation therapy (IMRT) for cervical cancer patients. Materials and methods: A retrospective study of 10 women with stage 1B1-3B cervical cancer diagnosed from September 2007 to July 2008 was conducted. All patients were treated with chemoradiation using IMRT followed by intracavitary brachytherapy. Pretreatment, patients had 2 seeds placed at a depth of 10 mm into the cervix. On-Board Imaging (OBI) was used to obtain anterior/posterior (AP) and lateral X-rays before and after each treatment. OBI images were rigidly aligned to baseline digitally reconstructed radiographs (DRRs), and movement of cervical seeds was determined in the lateral, vertical, and AP directions. Mean differences in cervical seed position and standard error of the mean (SEM) were calculated. Results: A total of 922 images were reviewed, with approximately 90 images per patient. The mean intra-fractional movement in cervical seed position in the lateral, vertical, and AP directions were 1.6 mm (SD ± 2.0), 2.6 mm (SD ± 2.4), and 2.9 mm (SD ± 2.7), respectively, with a range from 0 to 15 mm for each direction. The mean inter-fractional movement in the lateral, vertical, and AP directions were 1.9 mm (SD ± 1.9), 4.1 mm (SD ± 3.2), and 4.2 mm (SD ± 3.5), respectively, with a range from 0 to 18 mm for each direction. Conclusions: This is the first study to assess intra- and inter-fractional movement of the cervix using daily imaging before and after each fraction. Within and between radiation treatments, cervical motion averages approximately 3 mm in any given direction. However, maximal movement of the cervix can be as far as 18 mm from baseline. This wide range of motion needs to be accounted for when generating planning treatment volumes.

    Full Text Available ABSTRACT : BACKGROUND : Cervical cancer is the second most common cancer among women globally and a leading cause of death due to cancer among women. If diagnosed earlier, it has a high cure rate but advanced disease is frequently incurable with v ery unpleasant consequences. MATERIAL AND METHODS : This was a cross sectional study done on a group of 50 women. A detailed clinical history of each patient was taken. The patients were made to lie in dorsal lithotomy position and per speculum examination was done. After evaluating the cervix, Paps smear was taken for cytology with Ayers spatula from ectocervix after rotating at 360 degree and spread on 2 glass slides to prepare thin films and kept in koplin jar and sent for cytology reporting. The patients were then subjected to colposcopy and punch biopsy. RESULTS : On comparison with biopsy cervix as gold standard for detection of CIN, cytology had shown Sensitivity - 57.14%, Specificity - 88.88%, NPV - 84.21%, PPV - 66.66%, whereas colposcopy had shown Sen sitivity - 80%, Specificity - 80%, NPV - 94.11%, PPV - 50%. CONCLUSION : In developing countries like India, cytology, a low cost and easily accessible test, is the most logical screening modality although it has very low sensitivity but detection rates coul d be further improved using liquid cytology and use of endocervicalcytobrush. Colposcopy with high sensitivity is although an important adjunctive screening modality but requires expertise and training for interpretation and is costly

    Full Text Available Abstract Objective Increasing evidence indicates that type 2 diabetic patients are at elevated risk for developing different kinds of cancers. However, diabetes mellitus may be a protective factor for prostate cancer since both were found to be negatively associated. Based on the same genetic background, parents of diabetic patients might show similar risks concerning cancers. Research design and methods We conducted a case-control study, where familiy history of 794 type 2 diabetic cases and 775 non-diabetic controls was ascertained. Then, we expanded our study up to 801 type 2 diabetic cases and 1267 non-diabetic controls. Results Concerning the 794 type 2 diabetic patients and 775 controls, we observed that cancer of cervix uteri was elevated among mothers of controls (odds ratio (OR 0.19; 95% confidence interval (CI 0.02 to 0.88; p = 0.033. Mothers of diabetic patients showed an increased history of cancers of the liver and biliary tract (OR 5.23; 95% CI 1.87 to 19.9; p = 0.0009 and stomach (OR 3.84; 95% CI 1.47 to 12.4; p = 0.0049. Pancreatic cancers were found to be elevated in fathers of diabetic patients (OR 4.92; 95% CI 1.07 to 46.7; p = 0.039. Most notably, a lower number of prostate cancers was observed in fathers of diabetic patients (OR 0.47; 95% CI 0.22 to 0.94; p = 0.032. Since diabetic patients were 14.3 years older than the controls, higher levels of cancer history among parents of diabetic patients would have been expected. Thus, the observed lower level of history of prostate cancer can be regarded as highly reliable. The analysis of 801 type 2 diabetics and 1267 controls showed that cancer of stomach was elevated among mothers of controls (OR 2.67; p = 0.0106. In addition, stomach cancers were found to be elevated in fathers of diabetic patients (OR 2.10; p = 0.0141. In accordance with the previous investigation, we again obseved a lower number of prostate cancers in fathers of diabetic patients (OR 0.49; p = 0.0279. However

    Treatment with cloprostenol, a prostaglandin synthetic analogue, was evaluated in five queens with open-cervix pyometra. Cloprostenol was administered (5 μg/kg body weight SC) on 3 consecutive days and amoxicillin (20 mg/kg body weight IM) on 7 consecutive days. Transient post-injection reactions caused by cloprostenol administration included diarrhea, vomiting and vocalizations. Reactions began as quickly as 10 mins after cloprostenol administration and lasted as long as 30 mins. All queens improved clinically after cloprostenol treatment and remained healthy until the end of the study, 1 year after treatment. All queens resumed normal estrous cycles without further treatment and two (40%) delivered a normal litter.

    Lymphoma of the cervix is a rare disease. About 1.0% to 1.5% of extranodal lymphomas originates in the female genital tract. The clinical presentation of this condition is nonspecific and magnetic resonance imaging is important for diagnostic elucidation. The present report describes the case of a 80-year-old patient with lumbar pain, whose magnetic resonance imaging showed a large uterine mass. The final diagnosis was lymphoma. (author)

  7. Sacral plexus injury after radiotherapy for carcinoma of cervix

    International Nuclear Information System (INIS)

    A 42-year-old woman developed lower extremity weakness and sensory loss 1 year after external and intracavitary radiotherapy for Stage IB carcinoma of cervix. She has been followed for 5 years posttreatment, and the neurologic abnormalities have persisted, but no evidence of recurrent carcinoma has been found. We believe this to be a rare case of sacral plexus radiculopathy developing as a late complication after radiotherapy. Suggestions are made for improving the radiotherapy technique to prevent this complication in future cases

  10. In-Vitro effect of Ficus deltoidea on the contraction of isolated rat’s uteri is mediated via multiple receptors binding and is dependent on extracellular calcium

    Science.gov (United States)

    2013-01-01

    Background Ficus deltoidea, is a perennial herb that is used to assist labor, firm the uterus post-delivery and to prevent postpartum bleeding. In view of its claimed uterotonic action, the mechanisms underlying plant’s effect on uterine contraction were investigated. Methods Adult female SD rats were injected with 2 mg/kg 17β-oestradiol (E2) to synchronize their oestrous cycle. A day after injection, uteri were removed for in-vitro contraction studies. The dose dependent effect of Ficus deltoidea aqeous extract (FDA) on the tension produced by the isolated rat’s uteri was determined. The effects of atropine (2×10-8 M), atosiban (0.5 IU), THG113.31 (10 μM), oxodipine (0.25 mM), EDTA (1 mM), 2-amino-ethoxy-diphenylborate (2-APB) (40 mM) and thapsigargin (1 mM) on the maximum force of contraction (Emax) achieved following 2 mg/ml FDA administration were also investigated. Results FDA induced in-vitro contraction of the isolated rat’s uteri in a dose-dependent manner. Administration of atropine, atosiban and THG113.31 reduced the Emax with atosiban having the greatest effect. The Emax was also reduced following oxodipine and EDTA administration. There was no significant change observed following 2-APB administration. Thapsigargin, however, augmented Emax. Conclusions FDA-induced contraction of the isolated rat’s uteri is mediated via multiple uterotonin receptors (muscarinic, oxytocin and prostaglandin F2α) and was dependent on the extracellular Ca2+. Contraction, however, was not dependent on the Ca2+ release from the internal stores. This in-vitro study provides the first scientific evidence on the claimed effect of Ficus Deltoidea on uterine contraction. PMID:24330515

    Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers. This is potentially good news as effective vaccines are already available to prevent infections from carcinogenic strains of human papilloma virus, which causes cancer of the uterine cervix

    Pyometra is recognized as one of the main causes of disease and death in the bitch, and Escherichia coli is the major pathogen associated with this disease. In this study, 70 E. coli isolates from the uteri horn, mouth, and rectum of bitches suffering from the disease and 43 E. coli isolates from the rectum of clinically healthy bitches were examined for the presence of uropathogenic virulence genes and susceptibility to antimicrobial drugs. DNA profiles of isolates from uteri horn and mouth in bitches with pyometra were compared by REP, ERIC, and BOX-PCR. Virulence gene frequencies detected in isolates from canine pyometra were as follows: 95.7% fim, 27.1% iss, 25.7% hly, 18.5% iuc, and 17.1% usp. Predominant resistance was determined for cephalothin, ampicillin, and nalidixic acid among the isolates from all sites examined. Multidrug resistance was found on ∼ 50% pyometra isolates. Using the genotypic methods some isolates from uteri, pus, and saliva of the same bitch proved to have identical DNA profiles which is a reason for concern due to the close relationship between household pets and humans.

    Full Text Available Context: Cervical cancer is the second most common malignancy among women in India. There is thus a need to identify unexplored risk factors such as occupational exposure to tobacco dust to justify its increasing trend so as to recommend suitable preventive measures. Aims: The aim was to study the association between occupational exposure to tobacco dust with development of carcinoma cervix. Settings and Design: Case-control study done in two tertiary care hospitals in Mangalore. Methodology: 239 histologically confirmed new cases of cervical cancer and the equivalent number of age-matched controls from 2011 to 2012 were interviewed about occupational history of beedi rolling and related factors. Statistical Analysis: Chi-square test, unpaired t-test, logistic regression. Results: Exposure rate to tobacco dust following beedi rolling was 63 (26.4% among cases and 38 (15.9% among controls (P = 0.005, odds ratio [OR] =1.893. The latent period from occupational exposure of tobacco dust subsequent to beedi rolling and development of cervical cancer was found to be 26.5 ± 8.5 years. Adjusted OR of beedi rolling with development of cervical cancer was found to be 1.913 (P = 0.005 after controlling the confounding effect of tobacco usage and was 1.618 (P = 0.225 after controlling the effects of all confounders. Three-quarters of beedi rollers were working in conditions of inadequate ventilation and hardy anybody used face mask during work. About a quarter of participants underwent voluntary screening for cervical cancer. Conclusion: Occupational exposure to tobacco dust was found to be associated with risk of developing cervical cancer. Measures to promote awareness, timely screening of this disease along with the improvement in working conditions is required for improving the health status of beedi rollers and to minimize the incidence of carcinoma cervix in the community.

    Presented in this work are the results of investigation aimed at analysis of coordinate distributions for azimuths and ellipticity of polarization (polarization maps) in blood plasma layers laser images of three groups of patients: healthy (group 1), with dysplasia (group 2) and cancer of cervix uteri (group 3). To characterize polarization maps for all groups of samples, the authors have offered to use three groups of parameters: statistical moments of the first to the fourth orders, autocorrelation functions, logarithmic dependences for power spectra related to distributions of azimuths and ellipticity of polarization inherent to blood plasma laser images. Ascertained are the criteria for diagnostics and differentiation of cervix uteri pathological changes.

    Patient-derived xenograft (PDX) models of cancer are considered to reflect the biology and treatment response of human tumors to a larger extent than xenograft models initiated from established cell lines. The characterization of a panel of four novel PDX models of cervical carcinoma of the uterine cervix is described in this communication. The outcome of treatment differed substantially among the donor patients, and the PDX models were found to mirror the histology, aggressiveness, and metastatic propensity of the donor patients' tumors. Two of the models (BK-12 and LA-19) were highly metastatic, one model (ED-15) was poorly metastatic, and one model (HL-16) was non-metastatic. The primary tumors of the two highly metastatic models showed high density of intratumoral lymphatics, whereas the other two models did not develop intratumoral lymphatics. The potential of the models to metastasize to lymph nodes was associated with high expression of both angiogenesis-related genes and cancer stem cell-related genes. The models may be highly valuable for studying mechanisms linking lymph node metastasis to lymphangiogenesis, hemangiogenesis, and the presence of cancer stem cells. PMID:26828134

  19. Hydroxyurea: a radiation potentiator in carcinoma of the uterine cervix. A randomized double-blind study

    International Nuclear Information System (INIS)

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

  20. Effect of protracted whole-body gamma irradiation with 6.7 Gy and 4.8 Gy (700 and 500 R) on trypsin inhibition activity of blood, cervical mucus and on morphological structure of cervix in ewes

    International Nuclear Information System (INIS)

    The pattern of changes in the trypsin inhibition activities (TIA) of blood plasma, cervical mucus and the morphological structure of the cervix was studied in ewes exposed to 60Co radiation for seven and five days, the radiation doses being 6.7 Gy and 4.8 Gy, respectively. During exposure, the group of ewes irradaited with 4.8 Gy was given the Roboran vitamin addition and following irradiation ampicillin (5250 mg). TIA was determined from retardation of the hydrolysis of the synthetic substrate N-alpha-tosyl-p-nitroanilide by bovine trypsin; the TIA was expressed as the percentage of inhibited trypsin. Almost all the studied TIA values of blood plasma and cervical mucus were increased in the irradiated animals, the range being from 103.1 to 155.0% of the levels for non-irradiated ewes. A reduction was recorded only in the total TIA of blood plasma in the group irradiated with a dose of 6.7 Gy (83.1% of the values for non-irradiated animals). In the group of animals irradiated with 4.8 Gy and non Roboran administered, the TIA of cervical mucus was observed to decrease to 92.4%. It was found during the study of changes in the proportion of glands in the stroma and changes in epithelium thickness in the mucous membrane of the cervix uteri that the irradiated ewes had the epithelium thickness reduced to 95.3% to 65.5% and that their stromal gland number decreased to 75.4% to 79.7% of that recorded in non-irradiated animals. It was only in the group given the Roboran supplement that an increase to 123.7% of the gland number for untreated ewes was recorded on the tenth day after termination of the irradiation

  1. Trans-abdominal ultrasound (US) and magnetic resonance imaging (MRI) correlation for conformal intracavitary brachytherapy in carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Purpose: Trans-abdominal ultrasonography (US) is capable of determining size, shape, thickness, and diameter of uterus, cervix and disease at cervix or parametria. To assess the potential value of US for image-guided cervical cancer brachytherapy, we compared US-findings relevant for brachytherapy to the corresponding findings obtained from MR imaging. Materials and methods: Twenty patients with biopsy proven cervical cancer undergoing definitive radiotherapy with/without concomitant Cisplatin chemotherapy and suitable for brachytherapy were invited to participate in this study. US and MR were performed in a similar reproducible patient positioning after intracavitary application. US mid-sagittal and axial image at the level of external cervical os was acquired. Reference points D1 to D9 and distances were identified with respect to central tandem and flange, to delineate cervix, central disease, and external surface of the uterus. Results: Thirty-two applications using CT/MR compatible applicators were evaluable. The D1 and D3 reference distances which represent anterior surface had a strong correlation with R = 0.92 and 0.94 (p < 0.01). The D2 and D4 reference distances in contrast, which represent the posterior surface had a moderate (D2) and a strong (D4) correlation with R = 0.63 and 0.82 (p < 0.01). Of all, D2 reference distance showed the least correlation of MR and US. The D5 reference distance representing the fundal thickness from tandem tip had a correlation of 0.98. The reference distances for D6, D7, D8, and D9 had a correlation of 0.94, 0.82, 0.96, and 0.93, respectively. Conclusions: Our study evaluating the use of US, suggests a reasonably strong correlation with MR in delineating uterus, cervix, and central disease for 3D conformal intracavitary brachytherapy planning.

  2. Cervix carcinoma is associated with an up-regulation and nuclear localization of the dual-specificity protein phosphatase VHR

    International Nuclear Information System (INIS)

    The 21-kDa Vaccinia virus VH1-related (VHR) dual-specific protein phosphatase (encoded by the DUSP3 gene) plays a critical role in cell cycle progression and is itself regulated during the cell cycle. We have previously demonstrated using RNA interference that cells lacking VHR arrest in the G1 and G2 phases of the cell cycle and show signs of beginning of cell senescence. In this report, we evaluated successfully the expression levels of VHR protein in 62 hysterectomy or conization specimens showing the various (pre) neoplastic cervical epithelial lesions and 35 additional cases of hysterectomy performed for non-cervical pathologies, from patients under 50 years of age. We used a tissue microarray and IHC technique to evaluate the expression of the VHR phosphatase. Immunofluorescence staining under confocal microscopy, Western blotting and RT-PCR methods were used to investigate the localization and expression levels of VHR. We report that VHR is upregulated in (pre) neoplastic lesions (squamous intraepithelial lesions; SILs) of the uterine cervix mainly in high grade SIL (H-SIL) compared to normal exocervix. In the invasive cancer, VHR is also highly expressed with nuclear localization in the majority of cells compared to normal tissue where VHR is always in the cytoplasm. We also report that this phosphatase is highly expressed in several cervix cancer cell lines such as HeLa, SiHa, CaSki, C33 and HT3 compared to primary keratinocytes. The immunofluorescence technique under confocal microscopy shows that VHR has a cytoplasmic localization in primary keratinocytes, while it localizes in both cytoplasm and nucleus of the cancer cell lines investigated. We report that the up-regulation of this phosphatase is mainly due to its post-translational stabilization in the cancer cell lines compared to primary keratinocytes rather than increases in the transcription of DUSP3 locus. These results together suggest that VHR can be considered as a new marker for cancer

    2014-11-01

    Full Text Available Cervical cancer remains a significant cause of morbidity and mortality for women in developing countries, despite the fact that inexpensive, simple and effective screening methods are available. Visual inspection of the cervix with acetic acid (VIA can be used as part of a “screen and treat” program to identify precancerous lesions for cryotherapy treatment. This case report details how the VIA screening test was incorporated into the care of a patient presenting to a maternal health clinic in Thomonde, Haiti which was staffed by doctors and medical students from Emory University School of Medicine in collaboration with Haiti Medishare. As demonstrated here, the VIA test requires minimal materials, can be efficiently incorporated into a physical exams, provides immediate results, and is easily demonstrated to and performed by local healthcare providers. The straightforward and sensitive VIA technique is an ideal cervical cancer screening method for resource poor areas.

  12. Risk stratification of patients with advanced squamous cell carcinoma of cervix treated by radiotherapy alone

    International Nuclear Information System (INIS)

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

  13. Preprocessing for Automating Early Detection of Cervical Cancer

    2011-01-01

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

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

    Full Text Available OBJECTIVE: To estimate national and district cancer incidence for 18 major cancer sites in Colombia. MATERIAL AND METHODS: National and district incidence was estimated by applying a set of age, sex and site-specific incidence/mortality ratios, obtained from a population-based cancer registry, to national and regional mortality. The work was done in Bogotá (Colombia and Lyon (France between May 2003 and August 2004. RESULTS: The annual total number of cases expected (all cancers but skin was 17 819 in men and 18 772 in women. Among males the most frequent cancers were those of the prostate (45.8 per 100 000, stomach (36.0, and lung (20.0. In females the most frequent were those of the cervix uteri (36.8 per 100 000, breast (30.0, and stomach (20.7. Districts with the lowest death certification coverage yielded the highest incidence rates. CONCLUSIONS: In the absence of national population-based cancer registry data, estimates of incidence provide valuable information at national and regional levels. As mortality data are an important source for the estimation, the quality of death certification should be considered as a possible cause of bias.OBJETIVOS: Determinar la incidencia nacional y departamental para 18 tipos de cáncer en Colombia.

  16. Results of radiation therapy for carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Fifty-nine consecutive patients who were treated with radiation therapy for carcinoma of the uterine cervix between April 1982 and December 1986 were reviewed. Twelve patients were treated with low dose-rate intracavitary irradiation using radium-226, and 46 were treated with high dose-rate irradiation using a remote afterloading system combined with external irradiation, and the other one was treated with external irradiation alone. The 5-year-survival rates for stage Ib, IIa, IIb, IIIb, and IVa were 77.8, 85.7, 87.5, 45.5 and 40.0%, respectively. The 5-year-survival rates for the low and high dose-rates irradiation were 66.7 and 73.9%, respectively. The most common complication of radiation therapy was rectal bleeding, which required conservative treatment (grade 2) in 11 (18.6%). The morbidities for the low and high dose-rates irradiation were similar. The causes of death in 17 patients were local recurrence in 14, metastases in 2 and other specified in one. These findings suggest that high dose-rate intracavitary irradiation is as effective as low dose-rate irradiation for carcinoma of the uterine cervix, and that further efforts for controlling the local tumors with stage IIIb disease without an increased rate of side-effects is required.

  17. Changes in oxygenation during radiotherapy in carcinoma of the cervix

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to investigate changes in tumor oxygenation, assessed by polarographic needle electrode measurements, following fractionated external beam radiotherapy in carcinoma of the cervix. Methods and Materials: Normal and tumor tissue oxygenation was measured in 19 patients prior to radiotherapy and after 40-45 Gy of external beam radiotherapy delivered in 20 fractions over 4 weeks. All measurements were performed during anesthesia. Results: There was no significant difference in the level of normal tissue oxygenation pre- and post radiotherapy. The individual patient median tumor pO2 values ranged from 0 to 31 mmHg pre-radiotherapy and 1 to 61 mmHg post-radiotherapy. The mean of the 19 median pO2 values increased from 8 (SD ± 10) mmHg to 20 (± 20) mmHg following external beam radiotherapy. The increase was significant by paired Wilcoxon test (p = 0.011). There was also a significant fall in the proportion of values < 5 mmHg (p = 0.040). Although this value remained constant, or fell, in the majority of patients (15/19), it increased in 4 tumors. Tumor size pre- and post-radiotherapy did not correlate with the level of pretreatment oxygenation; neither did the change in tumor size and change in level of oxygenation. Conclusion: The level of tumor oxygenation increased in the majority of patients (15/19) following 40-45 Gy of radiotherapy in carcinoma of the cervix

    Background and purpose. Many observations on potential inadequate coverage of tumour volume at risk in advanced cervical cancer (CC) when conventional radiation fields are used, have further substantiated by investigators using MRI, CT or lymph-angiographic imaging. This work tries to obtain three dimensional margins by observing enlarged nodes in CT scans in order to improve pelvic nodal chains clinical target volumes (CTVs) drawing, and by looking for corroborative evidence in the literature for a better delineation of tumour CTV. Method. Eleven consecutive patients (seven males, four females, mean age 62 years, range 43 8) with CT diagnosis of nodal involvement caused by pathologically proved carcinoma of the cervix (n = 2), carcinoma of the rectum (n = 2), carcinoma of the prostate (n = 2), non-Hodgkin lymphoma (n 2), Hodgkin lymphoma (n = 1), carcinoma of the penis (n = 1) and carcinoma of the corpus uteri (n = 1) were retrospectively reviewed. Sixty CT scans with 67 enlarged pelvic nodes were reviewed in order to record the more proximal structures (muscle, bone, vessels, cutis or sub-cutis and other organs) to each enlarged node or group of nodes according to the four surfaces (anterior, lateral, posterior and medial) in a clockwise direction. Results. summary of the observations of each nodal chain and the number of occurrences of every marginal structure on axial CT slices is presented. Finally, simple guidelines are proposed. Conclusions. Tumour CTV should be based on individual tumour anatomy mainly for lateral beams as it results from sagittal T2 weighted MRI images. Boundaries of pelvic nodes CTVs can be derived from observations of enlarged lymph nodes in CT scans. (author)

  20. Clear cell carcinoma of the uterine corpus following irradiation therapy for squamous cell carcinoma of the cervix

    International Nuclear Information System (INIS)

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

    This report is concerned with multiple primary cancers developing in invasive uterine cancer. Second primary tumors were recorded 27 women with a total of 30 non-uterine cancer (exception of radiation-induced cancer). 17 patients of radiation-induced neoplasm were observed (Rectal cancer 4, soft part sarcoma 4, cancer of urinary bladder 3, bone tumor 3, uterin cancer 2 and cancer of Vulva 1). One case is 4 legions (corpus, sigma, thymoma and stomach), 2 cases are 3 lesions (uterine cervix, stomach and maxillay siuis: uterine cervix, thyroidal gland and radiation-induced soft part sarcoma). Only 5 of these 17 patients were known irradiated dose (50 Gy--55 Gy), however others unknown. The mean latent periods of 17 cases of radiation induced neoplasms are 19.4 years. 16 patients of late second cancers of the cervix appearing from 11 to 36 years (average 19.5 years) after initial radiotherapy were recorded.

    Full Text Available Fusion defects of the Müllerian ducts occur frequently and they have been described by the American Fertility Society. However, septate uterus with cervical duplication and longitudinal vaginal septum is not described by this classification and has suggested a change in the classical theory of fusion of the Müllerian ducts. This paper describes a rare case report of a patient with complete septate uterus with double cervix and longitudinal vaginal septum, submitted to the vaginal septoplasty for dyspareunia, progressing to clinical improvement. The description of this case is to contribute with all uncommon cases of Müllerian anomalies reports and clinical treatment protocols, which is not yet established.

  5. Brachytherapy as sole treatment modality in initial cervix carcinoma

    International Nuclear Information System (INIS)

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

  6. The dose time relationship in the radiotherapy of carcinoma of the cervix: application of CRE formalism

    International Nuclear Information System (INIS)

    A retrospective analysis of 291 patients with cancer of the uterine cervix treated with a combination of external and intracavitary radiotherapy was carried out. Patients were either treated with 45 Gy in 20 fractions by five fractions per week to with 42 Gy in 14 fractions by three fractions per week or with 42 Gy in 14 fractions by three fraction per week schedule by external radiotherapy. For brachytherapy the total dose was 24 to 32 Gy at a dose rate of 1.4 to 2.2 Gy per hour. Complication were correlated with total CRE values for point A (CREsub(TA)) and for rectum CREsub(TR). Correlations of CREsub(TA) with overall complication rate (p value 0.1) as well as rectal complication rate (p value >0.1). In order to limit Grade II and III rectal and bladder complications to acceptable level, in combined external and intracavitary treatments, CREsub(TA) value of less than 2500 reu is suggested.

  7. Combined radiotherapy and surgery : Local control and complications in early carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

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

  8. Sensitivity of T lymphocytes to gamma rays in patients with cervix tumor

    International Nuclear Information System (INIS)

    In this work we studied the effect of radiotherapy on normal cells in patients with cervix tumors treated only by gamma rays. In our laboratory, after lymphocytes separation, we tested the proliferation system of these cells against the phytohemagglutinin and the concanavalin a antigens; at the same time we tested their sensitivity to lys the erythroid tumor cells line K 562. According to the clinical stage of disease the 25 patients studied were divided in two groups; group I composed of 14 patients at stage I and II proximal, received 50 Gy from a cesium 137 source, in intrauterine and in continuous treatment during 4 days. The second group composed of 11 patients at stage II distal and III, received 50 Gy from a cobalt-60 source in extra uterine, the treatment is fractioned in 3 to 5 times per week, at each time the patient received 1,5 - 3 Gy. To compare with their immunological status before treatment, until 1 month after total dose received, all of our patients lost transitory their capacity to prolifere in vitro. Although the capacity to lys the tumor cells is diminished in cancer patients, the drop of this activity is principally. The selective recuperation of T lymphocytes stimulated by concanavalin A is also observed. 3 figs., 2 tabs

  9. Radiation therapy for carcinoma of the uterine cervix. Comparison of two brachytherapy schedules

    International Nuclear Information System (INIS)

    We compared the survival rates and late effects for two groups of cervical cancer patients treated with almost the same external radiotherapy but different remote afterloading systems (RALS) for high-dose-rate intracavitary radiation therapy regimens. A total of 218 patients with carcinoma of the uterine cervix were treated. For 98 patients, intracavitary brachytherapy was delivered with 6-7.5 Gy/fraction to Point A (Group A), and for 120, 5 Gy/fraction with a modified source step size (Group B). The 3-year cause-specific survival rates by stage and treatment schedule were Group A: 91% and Group B: 96% in Stage I, 89% and 92% in Stage II, 64% and 75% in Stage III, 44% and 69% in Stage IV. The survival curves did not reveal any statistically significant differences at any stage. The 3-year cumulative local failure rates were 14% in Group A and 7% in Group B (P = 0.1202), while the actuarial rates of developing rectal complication (Grade 2 or more) at 3 years were 25% in Group A and 4% in Group B (P < 0.0001). This retrospective analysis suggests that a low dose per fraction with modified source step size is advantageous because of yielding almost the same local control but with fewer rectal complications.

    OBJECTIVE To analyze clinical characteristics and treatment methods of the patients with adenocarcinoma of the uterine cervix (AUC) and adenosquamous carcinoma of the cervix (ASCC). To compare the survival time of the patients in 2 groups and analyze the prognostic factors.METHODS Clinical data of both 123 patients with AUC and 32 patients with ASCC treated at the Cancer Hospital, Chinese Academy of Medical Science (CAMS) & Peking Union Medical College (PUMC), were retrospectively analyzed.RESULTS The median age of the AUC patients was 50 years, and that of the ASCC patients was 44, P = 0.019. Poorly-differentiated (grade 3) cases accounted for 59.5% of the total ASCC patients,while only 32.5% of the AUC patients were in grade 3, P = 0.002.In 123 AUC patients, relapse or failure of the treatment occurred in 63 of the patients (51.2%), and the median relapse time was 6 months (0-59 months). In 32 ASCC patients, relapse or failure of the treatment occurred in 8 of these patients (51.2%), with a median relapse time of 4.5 months (0-52 months). The overall 5-year survival rate of the AUC patients was 49.8%, which was significantly lower than that of the ASCC patients (74.1%), P =0.015. The 5-year survival rates of the ASCC patients in Stage Ⅰ-Ⅲ were higher than that of the AUC patients with the same stages.However, statistical significant difference could only be found among the patients in Stage Ⅱ, P = 0.006. The 5-year survival rates of the ASCC patients with various differential grade were higher than those of the AUC patients with the same differential grade,but statistical significant difference could only be found among the patients in the two groups with moderately differentiation,P = 0.039. It was found by Cox regression analysis that only clinical stage (P < 0.001) and histological type (P = 0.046) were the independent prognostic factors.CONCLUSION Clinical stage and histological type were the independent prognostic factors of the AUC and ASCC patients

  11. Is cervical screening preventing adenocarcinoma and adenosquamous carcinoma of the cervix?

    2016-09-01

    While the incidence of squamous carcinoma of the cervix has declined in countries with organised screening, adenocarcinoma has become more common. Cervical screening by cytology often fails to prevent adenocarcinoma. Using prospectively recorded cervical screening data in England and Wales, we conducted a population-based case-control study to examine whether cervical screening leads to early diagnosis and down-staging of adenocarcinoma. Conditional logistic regression modelling was carried out to provide odds ratios (ORs) and 95% confidence intervals (CIs) on 12,418 women with cervical cancer diagnosed between ages 30 and 69 and 24,453 age-matched controls. Of women with adenocarcinoma of the cervix, 44.3% were up to date with screening and 14.6% were non-attenders. The overall OR comparing women up to date with screening with non-attenders was 0.46 (95% CI: 0.39-0.55) for adenocarcinoma. The odds were significantly decreased (OR: 0.22, 95% CI: 0.15-0.33) in up to date women with Stage 2 or worse adenocarcinoma, but not for women with Stage1A adenocarcinoma 0.71 (95% CI: 0.46-1.09). The odds of Stage 1A adenocarcinoma was double among lapsed attenders (OR: 2.35, 95% CI: 1.52-3.62) compared to non-attenders. Relative to women with no negative cytology within 7 years of diagnosis, women with Stage1A adenocarcinoma were very unlikely to be detected within 3 years of a negative cytology test (OR: 0.08, 95% CI: 0.05-0.13); however, the odds doubled 3-5 years after a negative test (OR: 2.30, 95% CI: 1.67-3.18). ORs associated with up to date screening were smaller for squamous and adenosquamous cervical carcinoma. Although cytology screening is inefficient at preventing adenocarcinomas, invasive adenocarcinomas are detected earlier than they would be in the absence of screening, substantially preventing Stage 2 and worse adenocarcinomas.

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

    Clear cell carcinoma of cervix is a very rare neoplasm accounting only 4% of all cervical adenocarcinomas. Intrauterine exposure to diethylstilbestrol (DES) is supposed to be causative factor for clear cell adenocarcinoma in childhood and young-age patients. We are reporting a case of clear cell carcinoma of cervix in a 49-years-old multiparous post-menopausal woman, who had no exposure to DES (in-utero) or synthetic non-steroidal estrogen.

We report a case of an incidental primary benign cervical schwannoma in a 48-year-old woman. In the English literature, a few cases of primary schwannoma of the cervix have been reported, which include seven cases of primary malignant cervical schwannoma and only two that are benign. These cases are reviewed in the follow...

    The extracellular matrix of the cervix that comprises collagen, elastin, proteoglycans and glycosaminoglycans (GAGs) is thought to have an essential role in cervical relaxation. This study investigated the proportion of collagen and smooth muscle as well as the GAGs in cervices obtained from healthy bitches at different stages of the estrous cycle and bitches with open- and closed-cervix pyometra. Cervices were collected after ovariohysterectomy. The proportion of collagen to smooth muscle was determined using Masson's trichrome staining. Alcian blue staining was used to evaluate the relative distribution of cervical GAGs. The proportion of cervical collagen relative to smooth muscle was higher at estrus compared to anestrus (P≤0.05). It was also higher (P≤0.05) in bitches with open- compared to those with closed-cervix pyometra. Overall, hyaluronan (HA) was the predominant GAG in the canine cervix. In the luminal epithelium, the staining intensity for HA was stronger in estrus than in anestrus (P≤0.05), but not in diestrus (P>0.05). On the contrary, the intensity for the combined keratan sulfate (KS) and heparan sulfate (HS) was stronger in anestrus than in estrus and diestrus (P≤0.05). In bitches with pyometra, the staining intensity of the stroma for KS and HS was weaker in open- compared to closed-cervix pyometra (P≤0.05). Collectively, the different profiles of collagen and GAG suggest that the metabolism of both collagen and GAGs in the canine cervix is associated with hormonal statuses during the estrous cycle and cervical patency of bitches with pathological uterine conditions, such as pyometra.

    As people with learning disabilities now live longer, they will experience the same age-related illnesses as the general population and cancer is a prime example of this. In women, cancer screening is used to detect early on-set of cancer of the breast and abnormalities of the cervix which might, if left untreated, develop into cancer.…

  1. HDR neutron brachytherapy for cervix carcinoma in Lithuania

    International Nuclear Information System (INIS)

    Between 1988 and December 1995, a total of 285 patients with stage I-17, with stage II-157, with stage III-104 and stage IV-7 carcinoma of the cervix were treated with a combination of external beam radiation or surgery and HDR brachytherapy. The dose prescription for HDR brachytherapy was point A. The goals of combined radiation therapy were to deliver a total dose of 60.5-68.5 Gy to point A and 53-58 Gy to the pelvic lymph nodes (point B) or 14 Gy-eq to point A in case of preoperative brachytherapy. Dosimetric planning was performed in Gray- equivalents by the use of PC-based computer programme. Relative biological effectiveness of the Cf-252 neutrons was physical gamma and neutron dose rate dependent. Most of the insertions were performed weekly when dose per fraction was 8-10 Gy or 2 insertions were done in one week at lower fractions. The median follow-up for the various stages of disease ranged from 0.5 to 6.5 year. Treatment results, acute and late toxicity will be discussed

  2. HPV Genotypes Predict Survival Benefits From Concurrent Chemotherapy and Radiation Therapy in Advanced Squamous Cell Carcinoma of the Cervix

    International Nuclear Information System (INIS)

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

    Although the Manchester system is still extensively used to prescribe dose in brachytherapy (BT) for locally advanced cervix cancer, many radiation oncology centers are transitioning to 3D image-guided BT, owing to the excellent anatomy definition offered by modern imaging modalities. As automatic dose optimization is highly desirable for 3D image-based BT, this study comparatively evaluates the performance of two optimization methods used in BT treatment planning—Nelder-Mead simplex (NMS) and simulated annealing (SA)—for a cervix BT computer simulation model incorporating a Manchester-style applicator. Eight model cases were constructed based on anatomical structure data (for high risk-clinical target volume (HR-CTV), bladder, rectum and sigmoid) obtained from measurements on fused MR-CT images for BT patients. D90 and V100 for HR-CTV, D2cc for organs at risk (OARs), dose to point A, conformation index and the sum of dwell times within the tandem and ovoids were calculated for optimized treatment plans designed to treat the HR-CTV in a highly conformal manner. Compared to the NMS algorithm, SA was found to be superior as it could perform optimization starting from a range of initial dwell times, while the performance of NMS was strongly dependent on their initial choice. SA-optimized plans also exhibited lower D2cc to OARs, especially the bladder and sigmoid, and reduced tandem dwell times. For cases with smaller HR-CTV having good separation from adjoining OARs, multiple SA-optimized solutions were found which differed markedly from each other and were associated with different choices for initial dwell times. Finally and importantly, the SA method yielded plans with lower dwell time variability compared with the NMS method.

  5. Perioperative and postoperative complications of intracavitary radiation for FIGO stage I-III carcinoma of the cervix

    International Nuclear Information System (INIS)

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

While a conservative approach has been studied, and may be effective in MISCC, a lower number of studies that recommend conservative treatment are available for MIAC. We report two cases of synchronous cervix lesions in two separate foci, MISCC and MIAC, who underwent fertility-sparing treatment with long-term follow-up. We describe clinical, histological, and immunohistochemical features of the two cases. The first case is a 41-year-old female with a diagnosis of MIAC of endocervical type, grade 1 differentiation, with a stromal invasion, associated with a separate area of squamous cell carcinoma (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1. The second case is a 45-year-old female with a diagnosis of plurifocal MISCC, associated with an MIAC of endocervical type with a stromal invasion (International Federation of Gynecology and Obstetrics/TNM stage: pT1a1G1. After multidisciplinary counseling, both patients accepted conization as definitive treatment.

    Full Text Available OBJECTIVE: To analyze the amount of glycosaminoglycans in the uterine cervix during each phase of the rat estrous cycle. DESIGN: Based on vaginal smears, forty female, regularly cycling rats were divided into four groups (n = 10 for each group: GI - proestrous, GII - estrous, GIII - metaestrous and GIV - diestrous. Animals were sacrificed at each phase of the cycle, and the cervix was immediately removed and submitted to biochemical extraction and determination of sulfated glycosaminoglycans and hyaluronic acid. The results were analyzed by ANOVA followed by the Bonferroni post-hoc test. RESULTS: The uterine cervix had the highest amount of total sulfated glycosaminoglycans and dermatan sulfate during the estrous phase (8.90 ± 0.55 mg/g of cetonic extract, p<0.001; and 8.86 ± 0.57 mg/g of cetonic extract, p<0.001. In addition, there was more heparan sulfate at the cervix during the proestrous phase (0.185 ± 0.03 mg/g of cetonic extract than during any other phase (p<0.001. There were no significant changes in the concentration of hyaluronic acid in the uterine cervix during the estrous cycle. CONCLUSION: Our data suggest that the amount of total sulfated glycosaminoglycans may be influenced by hormonal fluctuations related to the estrous cycle, with dermatan sulfate and heparan sulfate being the glycosaminoglycans most sensitive to hormonal change.

    The purpose of this study was to establish normal values for the volume of the uterus and cervix in MRI based on age and the menstrual cycle phase. We performed MRI of the pelvis in 100 healthy women. For the uterus, they were further divided into two groups: one with myomas and/or adenomyosis and one without either. The volume of the uterus and cervix and thickness of the uterine wall layers were analysed by age and the menstrual cycle phase. The mean volume of the uterus in both groups and the cervix significantly increased with age to reach its peak at 41-50 years, and then dropped. Likewise, the thickness of the endometrium and the junctional zone, but not the myometrium, significantly increased until 41-50 years, and then decreased. When we compared the volume of the uterus and cervix and the thickness of the uterine wall layers between the two phases of the menstrual cycle, we found no significant differences. The volume of the uterus and cervix and the thickness of the endometrium and junctional zone differ significantly with age, but not between the two phases of the menstrual cycle. Knowledge of MRI-related normal values can be expected to aid the early identification of uterine pathologies. (orig.)

    Bacteriologic culture samples were taken from the cervix in three groups of 10 healthy, sexually active women using barrier contraception, oral contraceptives, or a levonorgestrel-releasing intrauterine contraceptive device. Culture samples for Candida albicans and Trichomonas vaginalis were taken, a cytologic vaginal smear was obtained, and an amine sniff test was performed; these were in addition to a routine gynecologic examination. Multiple bacteria were isolated from the cervix in women using oral contraceptives or an intrauterine contraceptive device, whereas lactobacilli alone dominated the flora of women using barrier contraception. Significantly more anaerobic bacteria were isolated from the cervix in oral contraceptive and intrauterine contraceptive device users when compared with the barrier method users. Symptoms and findings evident of anaerobic vaginosis were associated with the occurrence of anaerobic bacteria in the cervix of three patients using the intrauterine contraceptive device. The results showed that the cervical bacterial flora in sexually active healthy women is rich in anaerobes that can be regarded as a normal finding in women using oral contraceptives or intrauterine contraceptive devices. Barrier contraception with a condom prevents this anaerobic shift and maintains a lactobacilli-dominated flora in the cervix. PMID:3953700

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

  17. Elimination of Specular reflection and Identification of ROI: The First Step in Automated Detection of Cervical Cancer using Digital Colposcopy

    CERN Document Server

    Das, Abhishek; Bhattacharyya, Debasis

    2011-01-01

    Cervical Cancer is one of the most common forms of cancer in women worldwide. Most cases of cervical cancer can be prevented through screening programs aimed at detecting precancerous lesions. During Digital Colposcopy, Specular Reflections (SR) appear as bright spots heavily saturated with white light. These occur due to the presence of moisture on the uneven cervix surface, which act like mirrors reflecting light from the illumination source. Apart from camouflaging the actual features, the SR also affects subsequent segmentation routines and hence must be removed. Our novel technique eliminates the SR and makes the colposcopic images (cervigram) ready for segmentation algorithms. The cervix region occupies about half of the cervigram image. Other parts of the image contain irrelevant information, such as equipment, frames, text and non-cervix tissues. This irrelevant information can confuse automatic identification of the tissues within the cervix. The first step is, therefore, focusing on the cervical bor...

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

    Full Text Available Of the approximately 80,000 new cases of all cancers detected every year in India, 10-15% are gynecological malignancies. As per population-based registries under the National Cancer Registry Program, the leading sites of cancer among women are the cervix uteri, breast, and oral cavity. About 50-60% of all cancers among women in India are mainly of the following four organs: cervix uteri, breast, corpus uteri, and ovaries. Over 70% of these women report for diagnostic and treatment services at an advanced stage of disease, resulting in poor survival and high mortality rates. Among all gynecological cancers, ovarian cancer is the deadliest one and, in 2/3 rd of the cases, is detected in an advanced stage. But, in India and in other developing countries, due to inadequate screening facilities for the preventable cancer cervix, this kills more women than any other cancer in females. Gynecology Oncologist as a sub-specialist has an immensely important role in curtailing the menace of gynecological malignancies by providing comprehensive preventive, curative, palliative and follow-up services, with the aim of assuring a good quality of life to women as a cornerstone of cancer management.

    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.

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

  3. Subsequent malignancies associated with carcinoma of the uterine cervix: including an analysis of the effect of patient and treatment parameters on incidence and sites of metachronous malignancies

    International Nuclear Information System (INIS)

    The incidence and sites of metachronous malignancies were retrospectively determined from the records of 763 patients seen at Yale University Medical Center and affiliated hospitals with previously untreated, invasive carcinoma of the uterine cervix from 1953-1972. These patients were treated predominantly with radiation therapy; follow-up status was known for periods of 5-25 years or until time of death in over 96% of the patients. Forty-four patients had second malignancies noted at least 6 months after the initial cervical cancer was diagnosed. The expected incidence of second malignancies was determined from the Connecticut State Tumor Registry data controlling for year of diagnosis of the cervical cancer, patient age, sex, and time at risk (person-years exposure). To correct for any error in estimation of second malignancies introduced by the existence of a latency period for the development of a second cancer, the expected incidence of malignancies was also computed for 5-year time intervals following the cervical cancer. No significant increase in second malignancies was found (observed/expected-44/36) for the entire follow-up period nor for any individual 5-year interval. However, a statistically significant increase in lung cancer and vulva-vaginal cancer was noted and a significant decrease in breast cancer was observed. Cox regression analyses were performed to study the effect of total radium exposure and total external beam treatment, adjusting for other factors. No statistically significant increased risks were found

  5. Contributions of imaging to radiation therapy planning for uterine cervix carcinoma

    International Nuclear Information System (INIS)

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

    Full Text Available Purpose: Role of risk factors in cervical carcinogenesis and strategies for control of the disease have been assessed from the accumulated cytological data, derived from 35 years of hospital-based screening in Lucknow, North India. Materials and Methods: A total of 36,484 women have been cytologically screened during a span of 35 years (April 1971 - June 2005 in the Gynaecology out patient department (OPD of Queen Mary′s Hospital. Results: The frequency of Squamous Intraepithelial Lesion (SIL and carcinoma was found to be 7.2% and 0.6%, respectively, in the present study. The study revealed high age and parity as a predominant factor in cervical carcinogenesis, while viral sexually transmitted disease (STDs -human papilloma virus (HPV and Herpes simplex virus (HSV were also largely associated with SIL cases. The study emphasized great value of clinically downstaging the cervical cancer by detecting cervical cancer in the early stage. The study also revealed a significant difference in the frequency of SIL in symptomatic and asymptomatic women. Conclusion: Based on the analyzed data, it was felt that single lifetime screening, which appears to be the most feasible and affordable mode for control of carcinoma cervix in developing countries like India, should be carried out in all women of high parity irrespective of age (with three or more children and in older women above the age of 40 years irrespective of parity.

    Full Text Available Cervix is an important part of the reproductive tract; in non-pregnant animals it remains closed during anestrus and diestrus and is open only during estrus. In pathological conditions like pyometra, the cervix may be open or closed but the control mechanism is not clearly known. Prostaglandin E2 (PGE2 is considered to be involved in changes of extracellular matrix via coupling to prostaglandin E receptor subtype 4 (EP4. This study investigated the expression of EP4 in the cervices of bitches during different stages of estrous cycle and those with pyometra. After ovariohysterectomy, cervices were collected from anestrus (n=6, estrus (n=12 and diestrus (n=6, open- (n=10 and closed-cervix pyometra (n=10 bitches. Cervical EP4 expression was observed at all the layers and the stages but the differences in EP4 expression either among bitches in different stages of the estrous cycle and between open- and closed-cervix pyometra were limited to only surface epithelium (SE. In cyclic bitches during estrus and in open-cervix pyometra bitches, significantly higher (P<0.05 EP4 expression was found in SE of uterine part than vaginal part. In SE of the uterine part, the expression was higher in the bitches during estrus than in anestrus and diestrus, and in the bitches affected by open-cervix than those with closed-cervix pyometra. The results suggest that regulation of cervical dilation appeared in the uterine part of the cervix. Moreover, EP4 may be involved in stimulating dilation of the cervix in both estrus and open-cervix pyometra bitches.

  10. NQO1 overexpression is associated with poor prognosis in squamous cell carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

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

    AIM: To evaluate the prevalence of abnormalities of the uterine cervix in women with inflammatory bowel disease (IBD) when compared to healthy controls.METHODS: One hundred and sixteen patients with IBD [64 with Crohn's disease (CD) and 52 with ulcerative colitis (UC)] were matched to 116 healthy controls by age (+/- 2 years) at the time of most recent papanicolaou (Pap) smear. Data collected consisted of age, race, marital status, number of pregnancies,abortions/miscarriages, duration and severity of IBD,Pap smear results within five years of enrollment, and treatment with immunosuppressive drugs. Pap smear results were categorized as normal or abnormal including atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LGSIL), and high-grade squamous intraepithelial lesion (HGSIL). RESULTS: The median age at the time of Pap smear was 46 (range: 17-74) years for the IBD group and matched controls (range: 19-72 years). There were more Caucasian subjects than other ethnicities in the IBD patient group (P = 0.025), as well as fewer abortions (P = 0.008), but there was no significant difference regarding marital status. Eighteen percent of IBD patients had abnormal Pap smears compared to 5% of controls (P = 0.004). Subgroup analysis of the IBD patients revealed no significant differences between CD and UC patients in age, ethnicity, marital status, number of abortions, disease severity, family history of IBD, or disease duration. No significant difference was observed in the number of abnormal Pap smears or the use of immunosuppressive medications between CD and UC patients (P = 0.793). No definitive observation could be made regarding HPV status, as this was not routinely investigated during the timeframe of our study.CONCLUSION: Diagnosis of IBD in women is related to an increased risk of abnormal Pap smear, while type of IBD and exposure to immunosuppressive medications are not. This has significant implications for

  14. Prognostic significance of s-phase fraction detected by antithymidine antibodies in epidermoid cervix carcinomas

    International Nuclear Information System (INIS)

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

    Full Text Available Primary malignant melanomas of uterine cervix are quite rarely seen neoplasms, and long-life prognosis of patients with this disease is poor. Immunohistochemical methods and exclusion of other primary melanoma sites are used to confirm the diagnosis. As with other melanomas, cervix malignant melanomas may also cause cardiac metastases. Cardiac metastases are among rarely seen but more commonly encountered cases, compared to primary cardiac tumors. Here, we present a case of biatrial cardiac metastases in a 73-year-old patient with uterine cervix malignant melanomas. The patient underwent echocardiography, cardiac magnetic resonance imaging, and computed tomography. Our report shows the importance of advanced diagnostic techniques, such as cardiac magnetic resonance, not only for the detection of cardiac masses, but for a better anatomic definition and tissue characterization. Although the cases of malignant melanomas leading to multiple cardiac metastasis were reported in literature, the metastatic concurrence of malignant melanomas in both right and left atriums is quite rarely encountered as metastatic malignant melanomas. Also, another intriguing point in our case is that the primary lesion of our case was stemmed from uterine cervix, but not skin.

    Full Text Available Under progesterone (P dominance, fluid loss assists uterine closure which is associated with pH reduction. We hypothesize that P inhibits uterine fluid secretion and HCO3- transport. Aim. to investigate the expression of Cystic Fibrosis Transmembrane Regulator (CFTR and Cl−/HCO3- exchanger (SLC26A6 under P effect. Method. Uteri from ovariectomized steroid replaced and intact rats at different stages of oestrous cycle were analyzed for changes in protein and mRNA expressions. Results. P inhibits CFTR and SLC26A6 proteins and mRNA expression while oestrogen (E causes vice versa. E treatment followed by P causes a reduction in these transporters’ mRNA and protein. Similar changes occur throughout the oestrous cycle; that is, CFTR mRNA expression was high at proestrus while SLC26A6 mRNA and protein expressions were increased at proestrus and estrus. At diestrus, however, the expression of these transporters’ protein and mRNA was reduced. Conclusion. Inhibition of CFTR and SLC26A6 expressions may explain the reduced fluid volume and pH under P-mediated effect.

    Purpose This study was conducted to investigate the incidence and survival outcomes of second primary cancers after the diagnosis of cervical cancer. Materials and Methods Data from the Korea Central Cancer Registry between 1993 and 2010 were reviewed and analyzed. Standardized incidence ratios (SIRs) of second primary cancers among women with cervical cancer were analyzed. Kaplan-Meier survival curves were constructed for cervical cancer patients with or without a second primary cancer. Results Among 72,805 women with cervical cancer, 2,678 (3.68%) developed a second primary cancer within a mean follow-up period of 7.34 years. The overall SIR for a second cancer was 1.08 (95% confidence interval, 1.04 to 1.12). The most frequent sites of second primary cancers were the vagina, bone and joints, vulva, anus, bladder, lung and bronchus, corpus uteri, and esophagus. However, the incidence rates of four second primary cancers (breast, rectum, liver, and brain) were decreased. The 5-year and 10-year overall survival rates were 78.3% and 72.7% in all women with cervical cancer, and for women with a second primary cancer, these rates were 83.2% and 65.5% from the onset of cervical cancer and 54.9% and 46.7% from the onset of the second primary cancer, respectively. Conclusion The incidence rates of second primary cancers were increased in women with cervical cancer compared to the general population, with the exception of four decreasing cancers. The 10-year overall survival rates were decreased in cervical cancer patients with a second primary cancer. PMID:26194366

  1. Papillary squamotransitional cell carcinoma of the uterine cervix: A histomorphological and immunohistochemical study of nine cases

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Background: Papillary squamotransitional cell carcinoma (PSCC is a distinctive subcategory of squamous cell carcinoma of the uterine cervix. It has a propensity for local recurrence and late metastasis. Histologically, it can be misinterpreted as transitional cell carcinoma, or other papillary lesions of the cervix including squamous papilloma, verrucous carcinoma or cervical intraepithelial neoplasia grade 3 with papillary configuration. Materials and Methods: Nine cases of PSCC of the uterine cervix were diagnosed on a cervical biopsy specimen on routine hematoxylin and eosin (H and E stained sections. Their clinic-morphological features were analyzed. The cases were further evaluated immunohistochemically by cytokeratin 7 (CK7, cytokeratin 20 (CK20, p53 and Ki-67. Results: The patients ranged in age from 35 years to 75 years; with abnormal uterine bleeding being the most common clinical presentation. All the cases showed papillary architecture with fibrovascular cores lined by multilayered atypical epithelium. Three cell types were observed: Clear, intermediate and basaloid. Stromal invasion was seen in five cases, whereas in the remaining four cases, the biopsy specimen was too superficial to definitely assess invasion. Immunohistochemically, eight cases were CK7 + /CK20 - and one case was CK7 - /CK20 - . All nine cases showed nuclear accumulation of mutant p53. Moderate and high proliferative activity was observed in two and seven cases, respectively. Five of patients for whom follow-up information was available underwent radical hysterectomy and two of them were disease free 18 months following treatment. Conclusion: PSCC of the uterine cervix are a clinicomorphologically distinct group of cervical lesions that display a morphologic spectrum. They are potentially aggressive malignant tumors that should be distinguished from transitional cell carcinoma and other papillary lesions of the uterine cervix.

  2. A trial of Ro 03-8799 (pimonidazole) in carcinoma of the uterine cervix: an interim report from the Medical Research Council Working Party on advanced carcinoma of the cervix

    International Nuclear Information System (INIS)

    A randomised controlled clinical trial of Ro 03-8799 (pimonidazole) was performed in advanced stage II and stage III squamous cell carcinoma of the uterine cervix. A total of 183 patients were contributed by 15 centres in Western Europe and co-ordinated by the Medical Research Council Trials Office in Cambridge. Analysis has shown poorer local tumour control with a hazard radio (HR) of 2.1 [95% confidence interval (CI) 1.2 to 3.7] and survival with a HR of 1.6 (95% CI 1.0 to 2.5) in the group given the Ro 03-8799. These results were not materially affected after adjustment of stage or haemoglobin levels in stratified analysis or to inadequate radiotherapy being given to the sensitiser group. A true adverse effect caused by the drug is a possible cause and this might be related to a drug-induced impairment of blood supply to the tumour. When compared with results recorded previously for advanced cervical carcinoma treated by radiotherapy, it was apparent that the tumour control and survival in the sensitiser arm was similar, but the control arm showed results superior to those previously recorded. Whatever is the explanation it can certainly be concluded that the radiosensitising drug, pimonidazole, gave no benefit in the radiotherapy of advanced cervical cancer. (author). tabs., figs

    Purpose: Cervical cancer is cancer that starts in the cervix, the lower part of the uterus (womb) that opens at the top of the vagina. It is the third most common type of cancer in women. Cervical cancers start in the cells on the surface of the cervix. Most cervical cancers are from squamous cells. It starts as a precancerous condition called dysplasia. This precancerous condition can be detected by a Pap smear and is 100% treatable. It can take years for precancerous changes to turn into ce...

    Full Text Available Based on the results of preoperative examination in 180 patients, the investigators studied and analyzed the specific features of ultra- sonic images of endometrial cancer in detail. The comprehensive study comprising color Doppler and energy mapping, three-dimen- sional echography with standard and variable-frequency transducers was conducted using the expert-class ultrasound equipment. A close analysis revealed the high informative value of complex ultrasonic tomography in the preoperative staging of cancer of the cor- pus uteri, in its early stages in particular.

  5. Long-term survival of hypoxia radiotherapy for carcinoma of uterine cervix

    International Nuclear Information System (INIS)

    Objective: To evaluate the relationship between long-term survival rate and protection to marrow and lymphoid tissues in the pelvis with hypoxia radiotherapy for uterine cervical carcinoma. Methods: 113 patients, confirmed as having carcinoma of uterine cervix by pathology, were randomly divided by the envelope method into two groups: hypoxia radiotherapy group (HRG, 57 patients) and conventional radiotherapy group (CRG, 56 patients). HRG was given by sustained inhaling hypoxia gas (oxygen physical volume = 0.105) for two minutes before the start of radiotherapy till the end of radiotherapy of each field and then repeated for the other field in the same way. The duration of irradiation to each field was less than five minutes. CRG was given with conventional radiotherapy. The irradiation dose in the midpelvical plane was 20-50 Gy depending on the different stages of cervical carcinomatous lesion. The dose of four-divided-field in the parametria was 15-34 Gy. The dose at point A of intracavitary therapy was 15-35 Gy. Results: The decreased value of peripheral blood white cells after treatment was (1.36 ± 1.27) x 109/L in HRG and (2.97±1.19) x 109/L in CRG(P<0.05). E flower ring test (EFRT) increased by (6.00 ± 2.39)% and lymphocyte transformation rate(LTR) increased by (3.78±1.83)% in HRG, but decreased by (3.97±1.88)% and (4.47±1.73)% in CGR(P<0.01). The 5-year survival rate was 65% in HRG and 57% in CRG(P<0.05). The incidence of complications such as radiation proctitis and radiocystitis was also of statistically significant (P< 0.01, 0.05). Conclusions: Hematopoisis and columnar immunity can be protected by hypoxia radiotherapy for uterine cervical cancer. As a result, both long-term survival rate and life quality of patients are expected to be improved. (authors)

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

  7. FIGO Stage IIIB squamous cell carcinoma of the uterine cervix: natural history, treatment results, and prognostic factors

    International Nuclear Information System (INIS)

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

    The primary goals of this study are to improve the accuracy of noninvasive diagnosis of early cervical cancer. In this study, a novel 3-D optical imaging system based on active stereo vision and motion tracking is developed to track the motion of patient and to register the time-sequenced images of cervix recorded during the examination of colposcopy. This technology can quantify the acetic acid induced optical signals associated with early cancer development at cervix. The results of a preliminary clinical study of 65 patients demonstrate that the accuracy to differentiate pre-cancerous cervical tissue from normal tissue can be significantly increased.

    Metastases to gastrointestinal tract are uncommon. In particular, metastases to the ampulla of Vater are very rare and may represent a significant diagnostic challenge. Metastases from the uterine cervix to the ampulla of Vater are exceedingly rare and only one case has been described in the available literature. We describe here a second case of metastatic squamous cell carcinoma of the cervix to the ampulla of Vater in a 45-year-old woman. Poorly differentiated squamous cell carcinoma prese...

    Purpose: To compare clinical behaviors and treatment outcomes between patients with squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix treated with radical hysterectomy (RH) and adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT). Methods and Materials: A total of 318 Stage IB-IIB cervical cancer patients, 202 (63.5%) with SCC and 116 (36.5%) with AC/ASC, treated by RH and adjuvant RT/CCRT, were included. The indications for RT/CCRT were deep stromal invasion, positive resection margin, parametrial invasion, or lymph node (LN) metastasis. Postoperative CCRT was administered in 65 SCC patients (32%) and 80 AC/ASC patients (69%). Patients with presence of parametrial invasion or LN metastasis were stratified into a high-risk group, and the rest into an intermediate-risk group. The patterns of failure and factors influencing survival were evaluated. Results: The treatment failed in 39 SCC patients (19.3%) and 39 AC/ASC patients (33.6%). The 5-year relapse-free survival rates for SCC and AC/ASC patients were 83.4% and 66.5%, respectively (p = 0.000). Distant metastasis was the major failure pattern in both groups. After multivariate analysis, prognostic factors for local recurrence included younger age, parametrial invasion, AC/ASC histology, and positive resection margin; for distant recurrence they included parametrial invasion, LN metastasis, and AC/ASC histology. Compared with SCC patients, those with AC/ASC had higher local relapse rates for the intermediate-risk group but a higher distant metastasis rate for the high-risk group. Postoperative CCRT tended to improve survival for intermediate-risk but not for high-risk AC/ASC patients. Conclusions: Adenocarcinoma/adenosquamous carcinoma is an independent prognostic factor for cervical cancer patients treated by RH and postoperative RT. Concurrent chemoradiotherapy could improve survival for intermediate-risk, but not necessarily high-risk, AC/ASC patients.

    The melanocytic cells of the cervical epithelium are capable of forming the complete spectrum of melanocytic lesions, from benign lentigines to melanoma. Primary malignant melanoma of the uterine cervix is a rare neoplasm with aggressive behavior. The absence of melanin pigment can lead to misdiagnosis as carcinomas, sarcomas, or lymphoma. Immunohistochemical studies should be used for confirmation. In order to consent the cervix as a primary site, exclusion of any other probable primary sites of melanoma is needed. Here, we present a 61-year-old female patient with postmenopausal vaginal bleeding. After cervical smear, diagnosis was confirmed by cervical punch biopsy. Diagn.

    The article serves to review the literature on the human uterine cervix based on a new distension technology named functional luminal imaging probe. This technology was originally developed to study the biomechanical competence of the gastro-esophageal junction where it provides a geometric profile of the lumen during distension, which can be related to sensory data. We searched and reviewed publications on cervical distention from 2002. The functional luminal imaging probe technology has been used for studying the mechanical and mechano-sensory properties of the cervix in non-pregnant women. In early pregnant women and in term pregnant women, the technique provides geometric measurements from the whole cervical canal during distension, which changes dramatically during pregnancy. Furthermore, it has been demonstrated that the technique predicts the outcome of labor induction better than the Bishop score does. The functional luminal imaging probe technology has potential as a research tool as well as for clinical use in gynecology and obstetrics. PMID:26946059

  15. Flow cytofluorometric evidence for the differential radioresponsiveness of aneuploid and diploid cervix tumours

    International Nuclear Information System (INIS)

    348 patients have been included in the study over a 54-month period. Data on these patients have shown that DNA aneuploid tumours are significantly more radioresponsive than diploid cervix tumours. Analysis of the data on 213 patients with a minimum follow-up time of 15 months has, however, failed to show an overall more favourable prognosis conferred by tumour DNA aneuploidy. Analysis of the relationship between clinical stage and disease state and tumour DNA ploidy, however, suggests that (1) aneuploid tumours metastasize to distant sites at an earlier stage of the disease than diploid tumours and (2) local recurrence rates for diploid tumours, in late stage disease, are double those for aneuploid tumours. Improved staining procedures, and instrument modification, has also shown that cervix tumour heterogeneity is of considerably greater frequency than at first appeared to be the case (approximately 75% of DNA aneuploid tumours show heterogeneity).

    The study shows the treatment of superficial endometriosis of the uterine cervix in 79 patients. After first vaporization 74 patients were cured successfully. In two cases the laser procedure should be repeated and in 3 women the operation should be performed for the third time. All patients are still under control in our department and there is no recurrence observed. Carbon- dioxide laser vaporization under colposcopic control is an efficient method of treatment of superficial endometriosis of the uterine cervix that requires no anaesthesia. The healing process after laser procedures is fast and without complications. The number of recurrences is low. Use of carbon-dioxide laser under colposcopic control because of precise destruction of lesions, fast healing and a low number of recurrences seems to be the method of choice.

  17. Dosimetry of intracavitary applications in carcinoma of the cervix: rectal dose analysis

    International Nuclear Information System (INIS)

    The International Commission on Radiation Units and Measurements (ICRU), in its Report-38, has given certain recommendations regarding the specifications of bladder and rectal reference points in the intracavitary treatment of carcinoma of the cervix. Conforming to this report, 182 intracavitary applications performed in stage I and II cervix cases were analyzed. In 113 applications, the maximum rectal dose was found to be in a point on the anteroposterior line drawn through the centre of colpostat sources. However, for our type of applications, the point on the anteroposterior line drawn through the lower end of the uterine tube seldom gets maximum dose. In addition, it was observed that there are other dose points than the ICRU reference point receiving doses close to maximum dose. It was concluded that doses to multiple rectal reference points should be recorded, in addition to the ICRU-defined rectal reference point

  18. Trends in the use of radiation and chemotherapy in the initial management of patients with carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

    Purpose: The Commission on Cancer of the American College of Surgeons conducts Patient Care Evaluation studies to describe practice patterns and trends in disease management. This report surveys changing strategies in the initial treatment of patients with invasive cancer of the uterine cervix. Methods and Materials: Using a standard data collection form designed by a multidisciplinary committee of specialists, cancer registrars at 703 hospitals submitted anonymous data on 11,721 total cervical cancer patients diagnosed in 1984 and 1990. Results: Between the two study years, the use of radiation as all, or a component, of the initial course of therapy declined from 70 to 60.3%, coincident with a 32.3% increase in the use of hysterectomy alone and a 33.7% reduction in the use of radiation alone. The percentage of all patients receiving combined hysterectomy and radiation (preoperative or postoperative) remained virtually unchanged--10.2% in 1984, and 9.3% in 1990. However, women who were treated by hysterectomy in 1990 were less likely to receive radiation as part of their treatment than patients treated by hysterectomy in 1984. Among patients treated by radiation without hysterectomy, the use of intracavitary brachytherapy techniques substantially exceeded interstitial brachytherapy techniques in both study years. Among patients treated by local radiation without hysterectomy, the frequency of adjunctive chemotherapy use increased from 6.9% in 1984 to 24.8% in 1990, with chemotherapy and radiation increasingly administered concurrently rather than sequentially. Although differences based on age, histology, race/ethnicity, and insurance status were observed, these general management trends were seen in all groups. Conclusions: Changes in the utilization of radiation and surgery may reflect the increasing surgical involvement of gynecologic oncologists in the management of early stage cervical cancer, rather than significant alterations in the demographics of the

    Full Text Available Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma. In patients with mucinous adenocarcinoma in the abdominal cavity, caution should be exercised in interpreting the possible primary site of the tumor on the basis of the immunohistochemical profiles. The presence of human papillomavirus (HPV DNA is assessed to determine whether the ovarian neoplasms were metastases or primary independent neoplasm. Approximately 90% of endocervical adenocarcinomas are related to high-risk human papillomavirus (hr-HPV with the remainder being unrelated to HPV. Both types metastasize to the ovaries very infrequently. Ovarian endocervical-type (mullerian mucinous tumors and tumors composed of a mixture of endocervical-type mucinous, serous endometrioid, squamous, and indifferent cells with abundant eosinophilic cytoplasm reported to date have been primarily limited to borderline and micro invasive types. We report a-36-yr old woman with adenocarcinomas of uterine cervix who also had ovarian mucinous borderline tumor.Case presentation: The patient presented with abnormal uterine bleeding and lower abdominal pain. She had a history of uterine cervix polyps. Pelvic ultrasound showed a right adnexal mass and a large cervical size. Histological diagnosis in uterine cervix biopsy revealed adenocarcinoma of cervix. Radical hysterectomy type III with bilateral salpingo-oophorectomy was performed. Histological finding in adnexal mass revealed borderline mucinous tissue of ovarian tumor. Testing for HPV DNA in the tumoral tissue was negative. This confirms that the ovarian tumor is not metastatic from endocervical adenocarcinoma. Conclusion: We conclude that in a patient with

    Uterine cervix represents a convenient model for the study of the gradual transformation of normal squamous epithelium via low- to high-grade squamous intraepithelial lesions (SILs). Because SIL, on the basis of the cytokeratins expressed, are thought to originate from the reserve cells, we analyzed whether SILs also show a reserve cell phenotype with respect to intercellular interactions.

    The clinical and pathological features of a case of multifocal lymphangioma circumscriptum of the vulva are reported in a patient with chronic lymphedema of a lower extremity. Ten years previously the patient had been treated for squamous cell carcinoma of the cervix. Although lymphangioma circumscriptum is an extremely rare complication of altered lymphatic drainage, the presence of multiple noninflammatory vesicular appearing lesions in this setting should suggest the correct diagnosis.

    To apply 3D multifrequency MR elastography (3DMMRE) to the uterus and analyse the viscoelasticity of the uterine tissue in healthy volunteers considering individual variations and variations over the menstrual cycle. Sixteen healthy volunteers participated in the study, one of whom was examined 12 times over two menstrual cycles. Pelvic 3DMMRE was performed on a 1.5-T scanner with seven vibration frequencies (30-60 Hz) using a piezoelectric driver. Two mechanical parameter maps were obtained corresponding to the magnitude (vertical stroke G* vertical stroke) and the phase angle (φ) of the complex shear modulus. On average, the uterine corpus had higher elasticity, but similar viscosity compared with the cervix, reflected by vertical stroke G* vertical stroke {sub uterine} {sub corpus} = 2.58 ± 0.52 kPa vs. vertical stroke G* vertical stroke {sub cervix} = 2.00 ± 0.34 kPa (p < 0.0001) and φ {sub uterine} {sub corpus} = 0.54 ± 0.08, φ {sub cervix} = 0.57 ± 0.12 (p = 0.428). With 2.23 ± 0.26 kPa, vertical stroke G* vertical stroke of the myometrium was lower in the secretory phase (SP) compared with that of the proliferative phase (PP, vertical stroke G* vertical stroke = 3.01 ± 0.26 kPa). For the endometrium, the value of vertical stroke G* vertical stroke in SP was 68 % lower than during PP (PP, vertical stroke G* vertical stroke = 3.34 ± 0.42 kPa; SP, vertical stroke G* vertical stroke = 1.97 ± 0.34 kPa; p = 0.0061). 3DMMRE produces high-resolution mechanical parameter maps of the uterus and cervix and shows sensitivity to structural and functional changes of the endometrium and myometrium during the menstrual cycle.

    A case of multicentric pigmented Bowen's disease in a 45 year old woman with a previous history of carcinoma of the cervix is described. The two conditions may have a common pathogenesis, and a preceding viral infection with herpes simplex or human papillomavirus could be of aetiological relevance. Patients with multicentric pigmented Bowen's disease may be at risk of developing other tumours of the genital tract. Treatment with carbon dioxide laser proved effective.

    Untoward side-effects of exposure of normal tissues surrounding tumor in the course of radiation treatment were avoided due to the use of a proton beam developed at the Institute of Theoretical and Experimental Physics. As a result, no post-treatment complications were observed in the surrounding tissues of the urinary bladder and rectum in 175 cancer patients (tumors of the vulva - 39 and cervix uteri - 136) who received a course of complex radiation treatment and preoperative irradiation.

    Two patients with radiation ulcers of the lower abdomen which had occurred after radiotherapy for cancer of the cervix uteri and was repaired with groin flap were reported. Effects of flaps in plastic and reconstructive surgery were also referred to. Besides defects in the lower abdomen, defects in the vulva, the perineum, and the upper region of the femur were probably reconstructed effectively with groin flaps.

    We propose confocal Raman imaging as a label-free single cell characterization method that can be used as an alternative for conventional cell identification techniques that typically require labels, long incubation times and complex sample preparation. In this study it is investigated whether cancer and blood cells can be distinguished based on their Raman spectra. 2D Raman scans are recorded of 114 single cells, i.e. 60 breast (MCF-7), 5 cervix (HeLa) and 39 prostate (LNCaP) cancer cells and 10 monocytes (from healthy donors). For each cell an average spectrum is calculated and principal component analysis is performed on all average cell spectra. The main features of these principal components indicate that the information for cell identification based on Raman spectra mainly comes from the fatty acid composition in the cell. Based on the second and third principal component, blood cells could be distinguished from cancer cells; and prostate cancer cells could be distinguished from breast and cervix cancer cells. However, it was not possible to distinguish breast and cervix cancer cells. The results obtained in this study, demonstrate the potential of confocal Raman imaging for cell type classification and identification purposes.

    Serous adenocarcinoma of the cervix (SACC) is a very rare tumor. Our study aimed to characterize the immune profile and human papillomavirus (HPV) status of SACC, in comparison with other serous adenocarcinomas arising in the female genital tract. The pathological specimens obtained from 81 patients with serous carcinoma of the uterine cervix (n = 12), 29 endometrium, 20 ovary and 20 patients with mucinous carcinoma of the uterine cervix were reviewed. We assessed the expression of WT-1, p53, p16, HER2, CEA, and CA125 by immunohistochemistry and HPV DNA by PCR in 12 SACC samples. Their immune profile was compared with that of uterine papillary serous carcinoma (UPSC), ovarian serous adenocarcinoma (OSA), and mucinous endocervical adenocarcinoma (MEA). WT-1 and HER2 were expressed in very few SACC samples (0 and 0%, respectively), but p16, CA125, CEA and p53 were present in 100, 92, 58 and 50%, respectively. The difference in WT-1 expression between SACC and UPSC, MEA is not significant, but SACC differ significantly from OSA (p UPSC, whereas the frequency of expression of WT-1 was significantly lower in SACC than OSA. It appeared that p53 expression was associated with worse clinical outcome in patients with SACC, and that HPV infection was related to its occurrence. PMID:25370301

  17. Elevated cyclooxygenase-2 expression correlates with diminished survival in carcinoma of the cervix treated with radiotherapy

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study was to examine the relationship between overall survival and prognostic factors in carcinoma of the cervix treated with radiation therapy. A clinicopathologic study was performed on 24 patients. Methods and Materials: Formalin-fixed, paraffin-embedded tumor biopsies were stained for Cyclooxygenase-2 (COX-2), Topoisomerase I, Topoisomerase II, and p53. Clinical factors such as stage, grade, tumor size, pre- and post-treatment hemoglobin level, and radiotherapy dose were also evaluated. Results: Median follow-up was 75 months for living patients. The only immunohistochemical or clinical factor that was associated with improved survival was decreased COX-2 distribution staining. High COX-2 distribution staining was associated with decreased overall survival (p=0.021) and decreased disease-free survival (p=0.015) by log-rank comparison of Kaplan-Meier survival curves. The 5-year overall survival rates for tumors with low vs. high COX-2 distribution values were 75% and 35%, respectively. COX-2 staining intensity was found to correlate positively with tumor size (p=0.022). Conclusion: These findings indicate that increased expression of COX-2 portends a diminished survival in patients with invasive carcinoma of the cervix treated with radiotherapy. Because COX-2 is an early-response gene involved in angiogenesis and inducible by different stimuli, these data may indicate opportunity to intervene with specific inhibitors of COX-2 in carcinoma of the cervix

    This prospective blinded study compared translabial ultrasound (TLU) and digital palpation of the cervix among women whose cervix could not be visualized adequately or at all with transabdominal ultrasound during the third trimester of pregnancy. The cervical canal and internal cervical os were adequately visualized during 109 of 113 TLUs (96%). The TLU was well tolerated by the patients; only two patients refused the TLU pending discussion of the technique with their obstetrician. Among 43 examinations of patients without clinical cervical effacement, TLU showed a cervical length of 2.5 to 4.2 cm (mean, 2.9 cm). An excellent correlation (R = 0.90) was noted between cervical length on TLU and percentage of cervical effacement on digital examination. The correlation between amount of cervical dilatation on TLU and on digital examination was not high (R = 0.58). We conclude that the measurements of cervical length on TLU correlate well with the amount of cervical effacement on digital examination and that TLU provides a rapid and well-tolerated alternative technique to visualize the third-trimester uterine cervix.

  19. Insufficiency fracture of the pelvis after the radiotherapy for carcinoma of the uterine cervix

    International Nuclear Information System (INIS)

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

    The incidence of oropharyngeal cancer and oral cancer is growing worldwide, both in young non-smokers and in young non-drinkers (smoking and drinking are considered the main risk factors). Epidemiologic studies suggest a strong association between the infection by human papillomavirus (HPV), especially types 16 and 18 (high oncological risk) which have already demonstrated their etiological role in anal tumours as well as in cervix cancer. There is clear epidemiologic evidence that both types...

  3. Extended-field radiation therapy for carcinoma of the cervix

    International Nuclear Information System (INIS)

    The survival of cervical carcinoma patients with paraaortic/high common iliac nodal metastases was evaluated by retrospective chart review during a 13-year interval. Thirty-three patients with cervical carcinoma and surgically documented nodal metastases received primary, extended-field radiation therapy. Overall 2-year and 5-year actuarial survival rates after diagnosis were 37% and 31%, respectively. Survival was analyzed in terms of the variables patient age, clinical stage, tumor histologic type, the presence of enlarged paraaortic/high common iliac lymph nodes, the extent of nodal involvement (microscopic versus macroscopic), the presence of intraperitoneal disease, and whether intracavitary brachytherapy was administered. The use of intracavitary radiation therapy was associated with improved local control and survival (P = 0.017). None of the other variables were statistically related to patient survival. Twenty-two of the patients died of cervical cancer and five are surviving without evidence of cancer. Four patients died of intercurrent disease. Two patients developed bowel-related radiation complications; both patients received chemotherapy concurrent with the radiation therapy. One of the two patients died of radiation enteritis. The use of extended-field radiation therapy does benefit a small group of patients and may result in extended patient survival

    A total of 103 cases of cancer of the uterine cervix, untreated previously, were treated with radiotherapy combined with daily intramuscular injection of Bleomycin 30 minutes before irradiation (BR therapy) in 12 institutions. Result showed that especially in cases of stage III, BR therapy was superior in primary local control rate (89.6%), recurrence rate (20.8%) and crude 5-year survival rate (56.5%) to that of nationwide statistics. No severe side effects were found. It was concluded that external radiotherapy could control advanced cancers of uterine cervix combining with intramuscular injection of Bleomycin. (author)

  8. How can laparoscopic management assist radiation treatment in cervix carcinoma?

    International Nuclear Information System (INIS)

    Purpose: To determine the role of laparoscopic lymphadenectomy (pelvis ± para-aortic nodes) and laparoscopic hysterectomy in cervical cancer compared to 'classic radical surgery' in patients undergoing surgery in comparison with modern imaging in patients treated with radiotherapy alone.Materials and methods: The limitations of modern imaging are presented as well as how complication rates can be increased when classic laparotomy is followed by radiation therapy.Laparoscopic procedures are described with particular emphasis on how to provide information on lymph node metastases with the risk of overlooking microscopic involvement. A number of clinical experiences are cited to illustrate this problem and show how treatment approaches can be adapted.Results: The role of laparoscopy is evaluated according to different clinical situations and treatment protocols emphasizing the possibilities offered by this method to the radiotherapist. Conclusion: When developing laparoscopic techniques for the management of cervical carcinoma, caution must be exercised to ensure that these techniques are not detrimental to the prognosis.

    Full Text Available Pain in carcinoma cervix is a multidimensional experience with sensory, affective and cognitive-evaluative components. Many patients do not receive adequate pain management because of a lack of proper assessment, misconceptions regarding the pharmacologic and non pharmacologic methods of pain management and failure to distinguish between different types of pain. In our audit pelvic and nodal recurrence were the commonest cause of pain presenting as as pelvic pain, [42%], lumbosacral plexopathy [40%] and abdominal pain [34%] [n = 30]. Pain on defaecation caused by rectal obstruction, and suprapubic pain due to pyometra can be relieved by colostomy and drainage. Very little literature is available on the pain syndromes associated with carcinoma cervix. The present article is a review of cancer and treatment related pains in carcinoma cervix.

  13. Detecting Temporal and Spatial Effects of Epithelial Cancers with Raman Spectroscopy

    Directory of Open Access Journals (Sweden)

    Matthew D. Keller

    2008-01-01

    Full Text Available Epithelial cancers, including those of the skin and cervix, are the most common type of cancers in humans. Many recent studies have attempted to use Raman spectroscopy to diagnose these cancers. In this paper, Raman spectral markers related to the temporal and spatial effects of cervical and skin cancers are examined through four separate but related studies. Results from a clinical cervix study show that previous disease has a significant effect on the Raman signatures of the cervix, which allow for near 100% classification for discriminating previous disease versus a true normal. A Raman microspectroscopy study showed that Raman can detect changes due to adjacent regions of dysplasia or HPV that cannot be detected histologically, while a clinical skin study showed that Raman spectra may be detecting malignancy associated changes in tissues surrounding nonmelanoma skin cancers. Finally, results of an organotypic raft culture study provided support for both the skin and the in vitro cervix results. These studies add to the growing body of evidence that optical spectroscopy, in this case Raman spectral markers, can be used to detect subtle temporal and spatial effects in tissue near cancerous sites that go otherwise undetected by conventional histology.

    Cervical cancer is the main cancer among women in sub-Saharan Africa, India and other parts of the developing world. Evaluation of screening performance of effective, feasible and affordable early detection and management methods is a public health priority. Five screening methods, naked eye visual inspection of the cervix uteri after application of diluted acetic acid (VIA), or Lugol's iodine (VILI) or with a magnifying device (VIAM), the Pap smear and human papillomavirus testing with the high-risk probe of the Hybrid Capture-2 assay (HC2), were evaluated in 11 studies in India and Africa. More than 58,000 women, aged 25-64 years, were tested with 2-5 screening tests and outcome verification was done on all women independent of the screen test results. The outcome was presence or absence of cervical intraepithelial neoplasia (CIN) of different degrees or invasive cervical cancer. Verification was based on colposcopy and histological interpretation of colposcopy-directed biopsies. Negative colposcopy was accepted as a truly negative outcome. VIA showed a sensitivity of 79% (95% CI 73-85%) and 83% (95% CI 77-89%), and a specificity of 85% (95% CI 81-89%) and 84% (95% CI 80-88%) for the outcomes CIN2+ or CIN3+, respectively. VILI was on average 10% more sensitive and equally specific. VIAM showed similar results as VIA. The Pap smear showed lowest sensitivity, even at the lowest cutoff of atypical squamous cells of undetermined significance (57%; 95% CI 38-76%) for CIN2+ but the specificity was rather high (93%; 95% CI 89-97%). The HC2-assay showed a sensitivity for CIN2+ of 62% (95% CI 56-68%) and a specificity of 94% (95% CI 92-95%). Substantial interstudy variation was observed in the accuracy of the visual screening methods. Accuracy of visual methods and cytology increased over time, whereas performance of HC2 was constant. Results of visual tests and colposcopy were highly correlated. This study was the largest ever done that evaluates the cross

    Cervical ripening is associated with loss of structural integrity and tensile strength, thus enabling the cervix to dilate at term. It is characterized by changes in glycosaminoglycan composition, increased water content, and a progressive reorganization of the collagen network. The peptide hormone relaxin via interaction with its receptor, relaxin family peptide receptor 1 (RXFP1), promotes tissue hydration and increases cervical hyaluronan (HA) concentrations, but the mechanisms that regulate these effects are not known. This study in relaxin mutant (Rln(-/-)) mice tested the hypothesis that relaxin regulates HA synthase and aquaporin (AQP) expression in the cervix. We also assessed expression of the RXFP1 protein by immunohistochemistry. Pregnant Rln(-/-) mice had lower Has2 and Aqp3 expression on d 18.5 of pregnancy and decreased cervical HA compared with wild-type Rln(+/+) mice. Chronic infusion of relaxin for 4 or 6 d in pregnant Rln(-/-) mice reversed these phenotypes and increased Has2 and Aqp3 compared with placebo controls. Relaxin-treated mice also had lower Has1 and Aqp5. Changes in gene expression were paralleled by increases in cervical HA and variations in AQP3 and AQP5 protein localization in epithelial cells of Rln(-/-) cervices. Our findings demonstrate that relaxin alters AQP expression in the cervix and initiates changes in glycosaminoglycan composition through increased HA synthesis. These effects are likely mediated through RXFP1 localized to subepithelial stromal cells and epithelial cells. We suggest these actions of relaxin collectively promote water recruitment into the extracellular matrix to loosen the dense collagen fiber network. PMID:23087172

    BACKGROUND In cervical adenocarcinoma, surgical treatment involves bilateral oophorectomy, which affects the long-term quality of life. The aim of our study was to access the incidence of ovarian metastasis in early-stage cervical adenocarcinoma and to suggest an algorithm for the triage of these patients to preserve the ovaries. MATERIAL AND METHODS A total 101 patients with cervical adenocarcinoma who had undergone radical hysterectomy with pelvic lymphadenectomy and bilateral oophorectomy were included in this study. Data on the clinicopathologic characteristics of the cases were collected and low risk factors for ovarian metastasis in early-stage cervical adenocarcinoma were analyzed. RESULTS The ovary metastasis rate of cervical adenocarcinoma in this study was 4.95%, while it is only 2% in stage IB1. Pathological grade, LSVI, lymph node status, tumor size, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis, while LSVI, lymph node status, depth of stromal invasion, and involvement of the junction of the cervix and the body of the uterus were associated with ovarian metastasis in stage IB. Multivariate analysis revealed that LVSI and lymph node metastasis were independent risk factors for ovarian metastasis in all stages of cervical adenocarcinoma, but involvement of the junction of the cervix and the body of the uterus was an independent risk factor for ovarian metastasis in stage IB. CONCLUSIONS The incidence of ovarian metastasis in cervical adenocarcinoma is low. Our study suggests that ovarian preservation is safe and feasible in patients with no risk factors for ovarian metastasis. Further prospective studies are warranted. PMID:26852916

    Nuclear and cytoplasmic oestrogen receptors (REN and REC) were sought in 5 normal cervices and in 43 specimens of squamous carcinoma of the cervix. All 3 tissues components of the 5 normal cervices contained both REN and REC. Thirty-five (81%) of the tumours contained receptors, but in only 9 (21%) were they found in both subcellular compartments. Twenty-four tumours (56%) had only REC and 2 had only REN. The potential therapeutic significance of these findings is not yet known, but it seems ...
