    Trends in breast, cervix uteri, corpus uteri and ovarian cancers in six population based cancer registries (Mumbai, Bangalore, Chennai, Delhi, Bhopal, and Barshi) were evaluated over a period of the last two decades. For studying trends we used a model that fits this data is the logarithm of Y=ABx which represents a Linear Regression model. This approach showed a decreasing trend for cancer of the cervix and increasing trends for cancers of breast, ovary and corpus uteri throughout the entire period of observation in most of the registries. The four cancers, breast, cervix, corpus uteri and ovary, constitute more than 50% of total cancers in women. As all these cancers are increasing, to understand their etiology in depth, analytic epidemiology studies should be planned in a near future on a priority basis.

    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 questioning 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 discharge, 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 questionaires and 49% by questioning by doctors. 6. Pains on sexual intercourse were found in 69% by questionaires and 49% by questionning by doctors. Most pains occurred at penis insertion and was thought to be due to atrophy and inflammation of vagina and external genitalia in most cases. 7. Both vaginal damage 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.

    Cancer is one of the main causes of death among young and middle-aged females. In case of some cancer sites there is a possibility of undertaking an intervention, which would diminish the risk of death--to this group belongs first of all malignant neoplasm of cervix uteri. The date of beginning first cervix uteri cancer screening in Poland is approaching, therefore presenting epidemiological opening balance and possible scenarios of changes it worthwhile. This work uses data on morbidity and mortality due to malignant neoplasm of cervix uteri cancer in Polish population. Time trends analysis was based on so-called "breakpoint" (joinpoint analysis). Cervix uteri cancer mortality trend is characterized by two breakpoints (1971 and 1993). In the period of 1963-1970 there was an increase of mortality and then after the trend reversed: percentage decline was estimated at the level of 0.8% yearly in 1971-1992 and 2.4% yearly in 1993-2002. Hypothetical scenarios of changes in cervix uteri cancer mortality show, that lack of intervention will cause mortality among Polish females at the level recorded in Finland 25 years ago. Optimistic variant would allow on diminishing mortality in Poland down to the level observed currently in Finland, in around 30 years. Implementing preventive cervix uteri cancer screening is currently the most urgent challenge of public health. If the preventive screening program will still be in the phase of plans and projects, then in 30 years time Poland will be in the point which Finland reached in the end of 1970s, and our civilizing underdevelopment will reach half a century.

    Full Text Available Early response genes are a group of proto-oncogenes that are the first to be activated in cell stimulation with different growth factors and to be involved in the regulation of cell proliferation and differentiation. Large amount of information supporting that altered expression of these genes is one of the central and earliest events of carcinogenesis has been accumulated. In this connection, it is promising to use early response genes as diagnostic and prognostic markers for the detection and combination therapy of cancer of the cervix uteri, one of the most common gynecological malignancies characterized by high mortality rates and difficulties in early diagnosis. The theoretical basis for these promises is the found mechanisms for the interaction of early response genes with human papillomavirus genome, the main cause of cervix uteri cancer.

    French uterine cancer recordings in death certificates include 60% of "uterine cancer, Not Otherwise Specified (NOS)"; this hampers the estimation of mortalities from cervix and corpus uteri cancers. The aims of this work were to study the reliability of uterine cancer recordings in death certificates using a case matching with cancer registries and estimate age-specific proportions of deaths from cervix and corpus uteri cancers among all uterine cancer deaths by a statistical approach that uses incidence and survival data. Deaths from uterine cancer between 1989 and 2001 were extracted from the French National database of causes of death and case-to-case matched to women diagnosed with uterine cancer between 1989 and 1997 in 8 cancer registries. Registry data were considered as "gold-standard". Among the 1825 matched deaths, cancer registries recorded 830 cervix and 995 corpus uteri cancers. In death certificates, 5% and 40% of "true" cervix cancers were respectively coded "corpus" and "uterus, NOS" and 5% and 59% of "true" corpus cancers respectively coded "cervix" and "uterus, NOS". Miscoding cervix cancers was more frequent at advanced ages at death and in deaths at home or in small urban areas. Miscoding corpus cancers was more frequent in deaths at home or in small urban areas. From the statistical method, the estimated proportion of deaths from cervix cancer among all uterine cancer deaths was higher than 95% in women aged 30-40 years old but declined to 35% in women older than 70 years. The study clarifies the reason for poor encoding of uterus cancer mortality and refines the estimation of mortalities from cervix and corpus uteri cancers allowing future studies on the efficacy of cervical cancer screening.

    Full Text Available The experience with serial renal scintigraphy demonstrated its high informative value and safety in evaluating the severity of intrarenal urine outflow disorders; however, failure to make an objective assessment of ureteral patency considerably limits its study. The set of studies, which is given in this paper, is devoted to precisely this, highly urgent, problem. The authors describe an original procedure for diagnosing impaired urine outflow along the ureters, which has been used during serial renal scintigraphy, define the visual and digital characteristics of normal and impaired urine outflow in the supravesical segment, and denote the criteria characterizing severe impair- ments of renal urine derivation along the ureters. Risk factors for urine outflow disorders have been identified in patients with cancer of the cervix uteri, who receive various treatment modalities.

    The paper presents a procedure of teleradiotherapy in patients with stages III-IV cancer of the cervix uteri with significant concurrent pathology. Control patients with the similar disease stages underwent combined radiation therapy. If there are contraindications to combined radiation therapy, teleradiotherapy is possible and required as an independent treatment that prolongs and improves the patients' like quality irrespective of the extent of a tumorous process.

    For a long time, combined external irradiation and brachytherapy has been considered as the standard treatment in patients with advanced cervical cancers. Recently, five clinical randomized trials assessing the role of cis-platin-based chemotherapy delivered concomitantly to radiotherapy have been conducted in the United States. Another clinical randomized trial assessing the role of epirubicin was conducted by the Queen Mary Hospital in Hong Kong. With more than 2,000 enrolled patients, these studies showed converging results with an overall and disease-free survival improvement in the arms combining cis-platin and epirubicin-based chemotherapy and irradiation. These combinations led to a significant decrease in loco-regional evolution or recurrence rates, or even in pulmonary metastases rates. The relative risk of recurrences was decreased by 50%. The relative risk of death was decreased by 40%. The differences, however, were less significant in patients with advanced stages III or IVA. Hematological and digestive acute toxicity was significantly higher in the radiochemotherapy groups, but long-term complications were comparable. The results of these randomized trials have led to a modification in the standard of treatment in these poor prognosis cervix cancers. Five of the randomized trials evidenced the superiority of cis-platin-based chemotherapy, but the optimal chemotherapeutic regimens remain to be defined.

    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 (Acta Oncol 2003; 42: 357-365). 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 cisplatin-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.

    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

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated.

    In koilocytotic dysplasia of the uterine cervix the DNA content in squamous cells was quantitated by cytophotometry in histological preparations stained according to Feulgen. Three patterns of DNA distribution in the squamous cells were found. In type one (21.4%) the cells had DNA content in the diploid and paradiploid zone of the histogram. In type two (35.7%) cells with triploid and tetraploid DNA values were found, but with a conspicuous modal class of cells. In type three no modal class cells were found (42.9%). The quantitative DNA changes in squamous cells show that some of the HPV induced alterations may be regarded as precancerous.

    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.

    Full Text Available Abstract Background Cervical uterine epithelial cells maintain a physiological and pathogen-free milieu in the female mammalian reproductive tract and are involved in sperm-epithelium interaction. Easily accessible, differentiated model systems of the cervical epithelium are not yet available to elucidate the underlying molecular mechanisms within these highly specialized cells. Therefore, the aim of the study was to establish a cell culture of the porcine cervical epithelium representing in vivo-like properties of the tissue. Results We tested different isolation methods and culture conditions and validated purity of the cultured cells by immunohistochemistry against keratins. We could reproducibly culture pure epithelial cells from cervical tissue explants. Based on a morphology score and the WST-1 Proliferation Assay, we optimized the growth medium composition. Primary porcine cervical cells performed best in conditioned Ham's F-12, containing 10% FCS, EGF and insulin. After cultivation in an air-liquid interface for three weeks, the cells showed a discontinuously multilayered phenotype. Finally, differentiation was validated via immunohistochemistry against beta catenin. Mucopolysaccharide production could be shown via alcian blue staining. Conclusions We provide the first suitable protocol to establish a differentiated porcine epithelial model of the cervix uteri, based on easily accessible cells using slaughterhouse material.

    The cell interrelations, and cellular attachment to the stroma in normal columnar epithelium and adenocarcinoma of the cervix uteri were examined by transmission and scanning electron microscopy. The application of rapid enzymatic digestion technique allows to visualize the topography of cell membranes, otherwise disguised in ordinary conditions. Four types of disordered epithelial sheets characterized by different apical, lateral and basal cell surface changes are described. Various alterations in morphology of the basement membrane and adjacent conjunctive tissue are associated with the tumor appearance. Marked deviations in cell-stroma contact may lead to the inversion of cell polarity revealed in cervical adenocarcinoma: cellular parts adjoining to stroma acquire characteristic features of the apical pole.

    2008-02-01

    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

    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. The number of people assisted in the campaigns has not reached one quarter of what was estimated in the first campaign and in the second one the number was even inferior. In light of this situation, this article

    Objective: To report treatment results of 512 cases of carcinoma of uteri and investigate the way to improve treatment effects. Methods: The 5-year survival rate and the factors influencing the prognosis of 512 cases of uteri were analyzed retrospectively. Results: The 5-year survival rate after radiotherapy was as follows: stage Ⅰ: 100%; stage Ⅱ: 74.5%; stage Ⅲ: 56.5%; stage Ⅳ: 28.6%. Overall 5-year survival rate was 65.4%, which was almost the same as traditional intracavitary injection (65.7%). The 5-year survival rate in cervix lesions more than 4 cm and those less than or equal to 4 cm in stage Ⅱ was 63.9% and 79.3%,respectively, with statistically significant difference (P<0.05). The 5-year survival rate of the patients with squamous carcinoma in stage Ⅱ was 77.0% and that with low differentiated squamous carcinoma was 64.0%respectively. Twenty-three (4.5%) out of 512 suffered from post-radiotherapy rectitis, 18 (3.5%) cystitis.Conclusion: the survival rate of the patients with cervix carcinoma subject to radiotherapy is stabilized to 65%. The diameter and pathological classes affect survival rate, respectively. Low radiotherapy dose decrease complications.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated. (authors)

    It is possible to induce labour in pathological pregnancies after artificial ripening of the cervix. The present study concerns 70 patients (45 primipara, 25 multipara). The main pathologies are hypertension of pregnancy and pregnancies past dates. Prostaglandin F2 alpha has been used with a Tylose gel containing 5 mg of PGF2 alpha introduced by the extra-amniotic route. The cervical change was noted using Bishop's score. The mean increase of the cervical score was 0.8 with the first PGF2 alpha gel. The total mean increase was 1.2. Two cases of hyperstimulation of the uterus were observed and they led to Caesarean section. Prostaglandin gel induced labour in 56% of the patients. The mean time between the introduction of the gel and the delivery was 14 h for primipara and 10 h for multipara. Other patients were induced with oxytocin on the following day. Epidural analgesia was widely used in this study (in 64% of cases). The mean duration of labour was 6 h 10 for primipara and 4 h 30 for multipara. 30% of the patients needed Caesarean section but there was a marked difference between primipara (36%) and multipara (4%). After a review of the literature the authors conclude that it is useful to ripen the cervix prostaglandin but, as foreign authors do, they think that PGE2 should be more efficient.

    A patient dose distribution was calculated by a 3D multi-group S N particle transport code for intracavitary brachytherapy of the cervix uteri and compared to previously published Monte Carlo results. A Cs-137 LDR intracavitary brachytherapy CT data set was chosen from our clinical database. MCNPX version 2.5.c, was used to calculate the dose distribution. A 3D multi-group S N particle transport code, Attila version 6.1.1 was used to simulate the same patient. Each patient applicator was built in SolidWorks, a mechanical design package, and then assembled with a coordinate transformation and rotation for the patient. The SolidWorks exported applicator geometry was imported into Attila for calculation. Dose matrices were overlaid on the patient CT data set. Dose volume histograms and point doses were compared. The MCNPX calculation required 14.8 hours, whereas the Attila calculation required 22.2 minutes on a 1.8 GHz AMD Opteron CPU. Agreement between Attila and MCNPX dose calculations at the ICRU 38 points was within +/- 3%. Calculated doses to the 2 cc and 5 cc volumes of highest dose differed by not more than +/- 1.1% between the two codes. Dose and DVH overlays agreed well qualitatively. Attila can calculate dose accurately and efficiently for this Cs-137 CT-based patient geometry. Our data showed that a three-group cross-section set is adequate for Cs-137 computations. Future work is aimed at implementing an optimized version of Attila for radiotherapy calculations.

    Conclusions: A women with a preinvasive lesion of cancer cervix can be asymptomatic. This requires a task force for mass screening of all women in the community. Community health workers begin screening of all women from 21 years onwards with Pap smear and colposcopy. The trained heath workers can be used for downstaging of cancer cervix leading to a dramatic reduction in the incidence of invasive carcinoma. Even when a colposcopist detects the invasive carcinoma, it is so early that an 85-100% five-year survival rate can be achieved. [Int J Reprod Contracept Obstet Gynecol 2016; 5(8.000: 2515-2518

    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.

    Full Text Available Abstract Background Cervical cancer (CC, a leading cause of cancer-related deaths in women worldwide, has been causally linked to genital human papillomavirus (HPV infection. Although a host of genetic alterations have been identified, molecular basis of CC development is still poorly understood. Results We examined the role of promoter hypermethylation, an epigenetic alteration that is associated with the silencing tumor suppressor genes in human cancer, by studying 16 gene promoters in 90 CC cases. We found a high frequency of promoter methylation in CDH1, DAPK, RARB, and HIC1 genes. Correlation of promoter methylation with clinical characteristics and other genetic changes revealed the following: a overall promoter methylation was higher in more advanced stage of the disease, b promoter methylation of RARB and BRCA1 predicted worse prognosis, and c the HIC1 promoter methylation was frequently seen in association with microsatellite instability. Promoter methylation was associated with gene silencing in CC cell lines. Treatment with methylation or histone deacetylation-inhibiting agents resulted in profound reactivation of gene expression. Conclusions These results may have implications in understanding the underlying epigenetic mechanisms in CC development, provide prognostic indicators, and identify important gene targets for treatment.

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

    We performed 17 intraarterial scintigraphies in six patients with recurrent cervix cancer. With Seldinger method, the agent (four different radiopharmaceuticals) was perfused at the same speed of infusion of anticancer drugs (25 cc/hour) through internal iliac artery. There were four different radiopharmaceuticals; {sup 131}I-Lipiodol, {sup 99m}Tc(Technetium)-HSA (Human Serum Albumin), {sup 99m}Tc-Sucralfate and {sup 99m}Tc-MAA (Macroaggregated Albumin). We evaluate the distribution pattern of radioactivity by the use of ratio of Tumor/Extratumor uptake (T/ET ratio). Our results reveals that {sup 99m}Tc-MAA scan showed the highest T/ET ratio and the other were not ideal agents for intraarterial therapy of recurrent cervix cancer. In conclusion, an ideal radioisotope and tracer which can block capillary, for example MAA, should be re-evaluated or produced in order to treat the patient with recurrent cervix cancer.

    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.

    The continued increase in incidence of some hormone-related cancers worldwide is of great concern. Although estrogen-like substances in the environment were blamed for this increase, the possible role of endogenous estrogens from food has not been widely discussed. We are particularly concerned about cows' milk, which contains a considerable quantity of estrogens. When we name cows' milk as one of the important routes of human exposure to estrogens, the general response of Western people is that "man has been drinking cows' milk for around 2000 years without apparent harm." However, the milk that we are now consuming is quite different from that consumed 100 years ago. Unlike their pasture-fed counterparts of 100 years ago, modern dairy cows are usually pregnant and continue to lactate during the latter half of pregnancy, when the concentration of estrogens in blood, and hence in milk, increases. The correlation of incidence and mortality rates with environmental variables in worldwide countries provides useful clues to the etiology of cancer. In this study, we correlated incidence rates for breast, ovarian, and corpus uteri cancers (1993-97 from Cancer Incidence in Five Continents) with food intake (1961-97 from FAOSTAT) in 40 countries. Meat was most closely correlated with the breast cancer incidence (r=0.827), followed by milk (0.817) and cheese (0.751). Stepwise multiple-regression analysis (SMRA) identified meat as the factor contributing most greatly to the incidence of breast cancer ([R]=0.862). Milk was most closely correlated with the incidence of ovarian cancer (r=0.779), followed by animal fats (0.717) and cheese (0.697). SMRA revealed that milk plus cheese make the greatest contribution to the incidence of ovarian cancer ([R]=0.767). Milk was most closely correlated with corpus uteri cancer (r=0.814), followed by cheese (0.787). SMRA revealed that milk plus cheese make the most significant contribution to the incidence of corpus uteri cancer ([R]=0

    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.

    Lymphoma of the uterine cervix is very rare. We report a case of diffuse large B cell lymphoma (DLBCL) involving the uterine cervix treated at a newly commissioned semiurban cancer centre in north India in 2015. Data for this study was obtained from the hospital electronic medical records and the patient's case file. 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. PMID:27597906

Data for this study was obtained from the hospital electronic medical records and the patient’s case file. 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.

    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.

    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).

    Full Text Available In Himachal Pradesh, cancer cervix is a major public health problem since it ranks as the number one female cancer. A case-control study of 226 newly diagnosed, histopathologically confirmed cases of cancer cervix and equal number of matched controls was conducted at Regional Cancer Center, Himachal Pradesh during the period from July 2008 to October 2009 with the objective to study the common factors associated with cancer cervix. Univariate analysis identified 10 risk factors associated significantly with the disease. On multiple logistic regression, however, only seven risk factors were found to be associated significantly with the disease. These were: Age at birth of first child, spacing between two children, age at marriage, literacy, socioeconomic status, multiparity, and poor genital hygiene. Risk factors such as poor genital hygiene, age at birth of first child <19 years, early marriage, illiteracy, multiparity, and low socioeconomic status were highly prevalent in the study subjects and were found to be significantly associated with cancer cervix.

    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

    This is a retrospective study of patients treated for cervix cancer staged IB2, IIA or IIB with bulky tumor (> 4cm). Treatment was concurrent radiotherapy (45Gy with 1,8Gy daily fraction) and chemotherapy (5 cycles of Platinum 40mg/m2/week). All patients underwent Brachytherapy (15Gy on the reference isodose according to Paris system) followed by surgery (radical abdominal hysterectomy and bilateral pelvic lymphadenectomy: Piver 3) Between October 1999 and December 2002, forty five patients were treated in this protocol. Median age was 46 years (21- 68). Histology was squamous cell carcinoma in 93% and glandular carcinoma in 7%. Average external radiation dose was 44Gy (20-50). Ninety three percent of patients had at least 3 cycles of chemotherapy and 46,5% received the planned 5 cycles. On the operative specimens, there was 62,5% complete response and only 7 pelvic node involvement (17,5%). Four postoperative complications were noted (one vascular injury, one urinary fistula, one phlebitis and one lymph collection). Preoperative combined radiotherapy and chemotherapy in the early bulky stages of uterine cervix cancer is well tolerated and "gives" a high rate of sterilisation. There was no increase in surgical morbidity.

    We examined 19 patients with post-irradiation intestinal injury in the uterine cervix cancer for 12 years between 1985 and 1996. We discuss the usefulness and complications of surgery, mainly colostomy. The patients aged from 36 to 80 (average age 61) were treated, and their disease states were 12 cases of rectovaginal fistula, 2 of small intestinal fisfula, 1 of rectum posterior membranous fistula, 3 of proctostenosis, and 14 of proctitis with hemorrhage (including duplication). Surgical methods used were 18 cases of colostomy (2 cases were treated under peritoneum mirror) and 2 of enterocolostomy (including duplication). Eleven out of 19 patients who underwent surgery are alive now. Generally the post-irradiation intestinal injury was intractable, and the method of treatments were limited due to the coexistence of various diseases. The colostomy is safe and less invasive. Therefore patients with uterine cervix cancer having various complications can obtain high quality of life (QOL) such as the improvement of anemia and/or the increase of digestion by the colostomy.

    Full Text Available The results of clinical study for efficacy of photodynamic therapy (PDT with radachlorine in patients with pre-cancer and cancer of cervix are represented. The study enrolled 30 patients including 4 patients with cervical erosion, 5 patients with cervical intraepithelial neoplasia II, 13 patients with cervical intraepithelial neoplasia III, 4 patients with carcinoma in situ and 4 patients with cervical cancer stage Ia. Radachlorine was administrated as single 30 minute intravenous injection at dose of 1,0 mg/kg of body weight 3 h before irradiation (wavelength of 662 nm, light dose of 300–350 J/cm2. The results of treatment in 26 (86,7% patients was assessed as complete tumor regression and in 4 (13,3% patients — as partial regression. In cervical erosion, intraepithelial neoplasia II and carcinoma in situ groups total regression was in all cases. In the cervical intraepithelial neoplasia III group total regression after first course of PDT was achieved in 77% of patients, in cervical cancer stage Ia group – in 75% of patients. From 3 to 6 months after first course of treatment all patients with partial tumor regression underwent the second course of PDT with complete regression. There were no side-effects due to radachorine or PDT in the course of treatment and during follow-up. Thus, PDT with Russian photosensitizer radachlorine showed high efficiency for treatment of pre-cancer and cancer of cervix

    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.

    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.

  1. Regulation of Inflammatory Pathways in Cancer and Infectious Disease of the Cervix

    Full Text Available Cervical cancer is one of the leading gynaecological malignancies worldwide. It is an infectious disease of the cervix, associated with human papillomavirus infection (HPV, infection with bacterial agents such as Chlamydia trachomatis and Neisseria gonorrhoea as well as human immunodeficiency virus (HIV. Furthermore, it is an AIDS-defining disease with an accelerated mortality in HIV-infected women with cervical cancer. With the introduction of robust vaccination strategies against HPV in the developed world, it is anticipated that the incidence of cervical cancer will decrease in the coming years. However, vaccination has limited benefit for women already infected with high-risk HPV, and alternative therapeutic intervention strategies are needed for these women. Many pathological disorders, including cervical cancer, are characterised by the exacerbated activation and maintenance of inflammatory pathways which are considered to be regulated by infectious agents. In cervical cancer, hyperactivation of these inflammatory pathways and regulation of immune infiltrate into tissues can potentially play a role not only in tumorigenesis but also in HIV infection. In this paper we will discuss the contribution of inflammatory pathways to cervical cancer progression and HIV infection and the role of HIV in cervical cancer progression.

    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.

    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.

    AIM: The aim of this study was to quantify the impact of different types and magnitudes of dosimetric uncertainties in cervix cancer brachytherapy (BT) on tumour control probability (TCP) and normal tissue complication probability (NTCP) curves. MATERIALS AND METHODS: A dose-response simulation....../NTCP model. Systematic uncertainties of 3-20% and random uncertainties with a 5-30% standard deviation per BT fraction were analysed. RESULTS: Systematic dose uncertainties of 5% lead to a 1% decrease/increase of TCP/NTCP, while random uncertainties of 10% had negligible impact on the dose-response curve...... at clinically relevant dose levels for target and OAR. Random OAR dose uncertainties of 30% resulted in an NTCP increase of 3-4% for planned doses of 70-80Gy EQD2. CONCLUSION: TCP is robust to dosimetric uncertainties when dose prescription is in the more flat region of the dose-response curve at doses >75Gy...

    Full Text Available 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 (slope50 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 (P< 0.001 were the only determinants for complete response (CR at 1 month following completion of radiotherapy. EXTRT tumor regression sigmoid curves obtained for various patient characteristics differed only for those with AGRT and PGRT with differences in TRD50, (P< 0.001; TRD80 (P< 0.001 and slope50 (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.

    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

    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. By comparing papers among 3 nations, we collected items for Korean uterine cervix cancer PCS. By consensus meeting

    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.

    The Chilean Ministry of Health announced the incorporation of a human papillomavirus (HPV) vaccine to prevent cervix uterine cancer (CUC) into the national immunization program during year 2014 This decision was adopted despite of two opposing documents and a significant decrease in cervical cancer associated mortality due to cytological cervical screening. The burden of disease attributed to CUC has declined in Chile and current cost-effectiveness studies should be reviewed considering this decreasing trend, the progressive decrease in coverage rates observed during the past years, the potential need for aditional doses and lower vaccine costs if vaccine is acquired through the PAHO revolving fund. Moreover, serious adverse events associated with these vaccines, which in some countries are more frequent than CUC associated mortality, have not been thoroughly evaluated and are probably underreported. The decision to incorporate the vaccine occurs in a context of progressive weakening of the national cervical screening program leading to a reduced population coverage. This situation jepeordizes the achievements already obtained and poses a challenge to vaccine introduction considering that not all the high-risk viral subtypes are included and thus the risk for CUC does not disappear making cervical screening a vital component of the program that needs to be maintained. This governmental resolution requires a more solid scientific foundation and should not be implemented without resolving current cervical screening shortcomings.

    The role of p53 as modulator of OxPhos and glycolysis was analyzed in HeLa-L (cells containing negligible p53 protein levels) and HeLa-H (p53-overexpressing) human cervix cancer cells under normoxia and hypoxia. In normoxia, functional p53, mitochondrial enzyme contents, mitochondrial electrical potential (ΔΨm) and OxPhos flux increased in HeLa-H vs. HeLa-L cells; whereas their glycolytic enzyme contents and glycolysis flux were unchanged. OxPhos provided more than 70% of the cellular ATP and proliferation was abolished by anti-mitochondrial drugs in HeLa-H cells. In hypoxia, both cell proliferations were suppressed, but HeLa-H cells exhibited a significant decrease in OxPhos protein contents, ΔΨm and OxPhos flux. Although glycolytic function was also diminished vs. HeLa-L cells in hypoxia, glycolysis provided more than 60% of cellular ATP in HeLa-H cells. The energy metabolism phenotype of HeLa-H cells was reverted to that of HeLa-L cells by incubating with pifithrin-α, a p53-inhibitor. In normoxia, the energy metabolism phenotype of breast cancer MCF-7 cells was similar to that of HeLa-H cells, whereas p53shRNAMCF-7 cells resembled the HeLa-L cell phenotype. In hypoxia, autophagy proteins and lysosomes contents increased 2-5 times in HeLa-H cells suggesting mitophagy activation. These results indicated that under normoxia p53 up-regulated OxPhos without affecting glycolysis, whereas under hypoxia, p53 down-regulated both OxPhos (severely) and glycolysis (weakly). These p53 effects appeared mediated by the formation of p53-HIF-1α complexes. Therefore, p53 exerts a dual and contrasting regulatory role on cancer energy metabolism, depending on the O₂level.

    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.

    A trial comparing two different radiotherapy techniques and schedules is the treatment of 83 patients with advanced cancer of the uterine cervix (stage IIIB) employing external irradiation alone is described. The one technique, used routinely in this department, employed a conventional daily fractionation schedule while the other used a high-dose weekly fractionation regimen. The techniques are described. The aim of the trial was to compare the efficacy and morbidity of these two methods of treatment. Dose distribution curves in cross-section and midsagittal planes are shown and calculations or equivalent doses at various selected points using Ellis's nominal single-dose formula are tabulated. The 2-year survival figures were 33% for the daily fractionation technique and 22% for the weekly regimen. Serious late complication rates were 6% for the daily regimen and 22% for the weekly schedule. These differences are not statistically significant. Late complication rates in the weekly fractionation regimen appeared to be lower than figures quoted by other authors. Local control within the irradiated volume was better in the group treated by the daily fractionation method.

    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.

    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.

    Objective: This study was to compare 5 field conformal technique to the intensity modulated radiotherapy (IMRT) 8 fields technique in boosting locally advanced cancer cervix cases after external beam radiotherapy with respect to target volume coverage and dose to normal tissues. Methods: We conducted a single institutional comparative dosimetric analysis of 10 patients with cancer cervix who was presented to radiotherapy department in National Cancer Institute, Cairo in period between June 2012 to September 2012 and received a CRT boost in the place of planned brachytherapy after large field pelvic radiotherapy (PRT) with concurrent chemotherapy were retrospectively identified. All tumors were situated in the low central pelvis. Two plans were done for every patient; one using the 8 fields IMRT and the second one using 5 fields' 3DCRT the two techniques were then compared using dose volume histogram (DVH) analysis for the PTV, bladder, rectum and both femoral heads. Results: Comparing different DVHs, it was found that the planning target volume (PTV) was adequately covered in both plans while it was demonstrates that the 8 fields IMRT technique carried less doses reaching OARs (rectum, bladder, both femoral heads). Conclusion: From the present study, it is concluded that IMRT technique spared more efficiently OARs than CRT technique but both techniques covered the PTV adequately so whenever possible IMRT technique should be used.

    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

    Purpose To evaluate tumor shrinking kinetics in order to implement image-guided brachytherapy (IGBT) for the treatment of patients with cervix cancer. Material and methods This study has prospectively evaluated tumor shrinking kinetics of thirteen patients with uterine cervix cancer treated with combined chemoradiation. Four high dose rate brachytherapy fractions were delivered during the course of pelvic external beam radiation therapy (EBRT). Magnetic resonance imaging (MRI) exams were acquired at diagnosis (D), first (B1), and third (B3) brachytherapy fractions. Target volumes (GTV and HR-CTV) were calculated by both the ellipsoid formula (VE) and MRI contouring (VC), which were defined by a consensus between at least two radiation oncologists and a pelvic expert radiologist. Results Most enrolled patients had squamous cell carcinoma and FIGO stage IIB disease, and initiated brachytherapy after the third week of pelvic external beam radiation. Gross tumor volume volume reduction from diagnostic MRI to B1 represented 61.9% and 75.2% of the initial volume, when measured by VE and VC, respectively. Only a modest volume reduction (15-20%) was observed from B1 to B3. Conclusions The most expressive tumor shrinking occurred in the first three weeks of oncological treatment and was in accordance with gynecological examination. These findings may help in IGBT implementation. PMID:27648083

    The efficacy of the nationwide screening programme for cervical cancer in the Federal Republic of Germany, which has been in effect since 1971, has never been checked by means of controlled epidemiological studies. Therefore routinely collected mortality and morbidity data are up to now the only indicators of potential progress in early detection. Mortality statistics of cervical cancer are of restricted value due to lack of specificity regarding the cause of death on death certificates. Data of the population based cancer registry of Saarland are used to investigate trends in terms of age, stage and birth cohort-specific detection rates of cervical cancer and its preinvasive precursors. There was a substantial decrease in incidence rates of invasive cervical cancer, which was most pronounced for advanced tumour stages and young and middle-age groups and which is consistent with comparable results in other countries following the introduction of screening programmes. However, a selection effect of the screening programme suggested by a decrease in survival rates of women with invasive cervical cancer in the 1980ies, must also be taken into account.

    We wanted to describe the MR imaging findings of endometrial cancer in patients with a history of prior radiation therapy for cervical cancer (ECRT) and we compare them to the MR imaging findings of patients with spontaneously occurring endometrial cancer (SEC). Twenty-two patients with endometrial cancer that was diagnosed by operation or endometrial biopsy were included in the study. The patients were divided into two groups according to the presence of past RT for cervical cancer: ECRT (n = 4) and SEC (n = 18). The MR images were retrospectively analyzed by consensus of two experienced radiologists. The MR imaging findings were analyzed by the size, shape and signal intensity of the mass, distension of the uterine cavity, the presence of cervical stenosis and the nature of the fluid collection. For the mass shape, all the ECRT lesions were polypoid masses. However, the SEC patients had 5 polypoid masses and 13 wall thickenings. The maximal diameter, signal intensity and enhancement pattern of the masses were not different between the ECRT and SEC patients. The width of the endometrial cavity varied between 3.9 cm in the ECRT patients and 0.4 cm in the SEC patients ({rho} = 0.002). All the ECRT patients had cervical stenosis. However, none of the SEC patients had cervical stenosis. MR imaging of ECRT patients demonstrated prominent distension of their uterine cavity and cervical stenosis, which may be the result of radiation fibrosis in the uterus.

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.

    Full Text Available Abstract Introduction The raw incidence of cancer of the uterine cervix is Spain is 7,8 per 100.000 inhabitants (adjusted incidence is 5.6. The incidence of this tumor is still low, but a steady increase has been seen, probably related to increasing risk factors. Aim To determine the frequency of infection by different types of human papillomavirus (HPV in Papanicolau smears from women with and without cancer of the uterine cervix in Spain. Patients and methods A case-control study was performed in women with and without cervical cancer from Zaragoza, Spain. Pap smears from 600 cases (540 women with cervical intraepithelial neoplasms (CIN and 60 with invasive cancer and 1200 controls (women without those lesions were tested by polymerase chain reaction (PCR and typed by oligonucleotide microarray-based detection. Results HPV was detected in 93.3% of all samples with invasive cancer versus 17.5% of controls. OR for invasive cancer was 55 (95% CI 21.5–140,5. Statistically significant associations were also found for different grades of cervical dysplasia. Conclusion The strong association found between HPV infection, specifically types 16 and 18 and cancer of the uterine cervix in Zaragoza, Spain, stresses the importance of ongoing efforts to institute a vaccine program with recently approved HPV vaccines in order to prevent cervical cancer in this population.

    In radiotherapy for cervix cancer, both 3-dimensional radiotherapy (3D-CRT) and intensity-modulated radiation therapy (IMRT) could reduce the dose to the small bowel (SB), while the small bowel displacement system (SBDS) could reduce the SB volume in the pelvic cavity. To evaluate the effect of the SBDS on the dose to the SB in 3D-CRT and IMRT plans, 3D-CRT and IMRT plans, with or without SBDS, were compared. Ten consecutive uterine cervix cancer, receiving curative radiotherapy, were accrued. Ten pairs of computerized tomography (CT) scans were obtained in the prone position, with or without SBDS, which consisted of a Styrofoam compression device and an individualized custom-made abdominal immobilization device. Both 3D-CRT, using the 4-field box technique, and IMRT plans, with 7 portals of 15 MV X-ray, were generated for each CT image, and prescribed 50 Gy (25 fractions) to the isocenter. For the SB, the volume change due to the SBDS and the DVHs of the four different plans were analyzed using paired t-tests. The SBDS significantly reduced the mean SB volume from 522 to 262 cm{sup 3} (49.8% reduction). The SB volumes that received a dose of 10 {approx} 50 Gy were significantly reduced in 3D-CRT (65 {approx} 80% reduction) and IMRT plans (54 {approx} 67% reduction) using the SBDS. When the SB volumes that received 20 {approx} 50 Gy were compared between the 3D-CRT and IMRT plans, those of the IMRT without the SBDS were significantly less, by 6{approx} 7%, than those for the 3D-CRT without the SBDS, but the volume difference was less than 1% when using the SBDS. The SBDS reduced the radiation dose to the SB in both the 3D-CRT and IMRT plans, so could reduce the radiation injury of the SB.

    2010-10-01

    Full Text Available Abstract Background Poly-ADP-ribosylation, a reversible post-translational modification of primarily chromosomal proteins, is involved in various cellular and molecular processes including carcinogenesis. ADP-ribose polymer or poly-ADP-ribose adducts are enzymatically added onto or stripped off the target chromosomal proteins during this metabolic process. Due to this, the chromatin superstructure is reversibly altered, which significantly influences the pattern of gene expression. We hypothesize that a decrease in the concentration of total poly-ADP-ribose adducts of peripheral blood lymphocyte (PBL proteins strongly correlates with the incidence of human cancer. Results Using a novel immunoprobe assay, we show a statistically significant (P ≤ 0.001 reduction (~ 42 to 49% in the level of poly-ADP-ribose adducts of PBL proteins of patients with advanced cancers of head & neck (H & N region (comprising fourteen distinct cancers at different sites, breast and cervix in comparison to healthy controls. Conclusions These findings imply potential utility of the poly-ADP-ribose adducts of PBL proteins as a novel and general biomarker of human cancers with potentials of significant clinical and epidemiological applications.

    In this study, we synthesized tungsten oxide (WO3) nanoplates, both crystallographic phases and the morphology of the samples were determined by powder x-ray diffraction and the scanning electron microscopy, respectively. The obtained data clarified that, the all prepared WO3·H2O samples were composed of large quantity of nanoplates. The cytotoxicity patterns of nanoplates were checked on both normal and cancer mammalian cell lines. Both nanoplates cytotoxicity did not exceed the 50 % inhibitory concentration (IC50) on the all normal tested cells even by using concentrations up to 1 mg/ml. In addition, orthorhombic tungsten oxide nanoplate was more potent against both Caco2 and Hela cells by showing inhibition percentages in cellular viability 64.749 and 72.27, respectively, and with cancer selectivity index reached 3.2 and 2.6 on both colon and cervix cancer, respectively. The anticancer effects of nanoplates were translated to alteration in both pro-apoptotic and anti-apoptotic genes expressions. Tungsten oxide nanoplates down regulated the expression of B cell lymphoma 2 (Bcl-2) and metalloproteinase-7 (MMP7) genes. In addition, orthorhombic tungsten oxide nanoplates showed more potentiation in IL2 and IL8 induction (40.43 pg/ml) and upregulation of TNF-α gene expression but with lower folds than Escherichia coli lipopolysaccharide (LPS) induction.

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

    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.

    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.

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

  4. Interobserver variation in rectal and bladder doses in orthogonal film-based treatment planning of cancer of the uterine cervix

    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.

    Full Text Available Surfactin is one of the most powerful biosurfactants that has been known so far. It is an acidic cyclic nonribosomal lipoheptapeptide that is produced by Bacillus subtilis. In this presentation we investigated different properties of surfactin C-15. The nanomicelle forming ability of surfactin C-15 in different aqueous environments with various ionic strengths was studied by scanning electron microscope. Surfactin second structure was investigated by Far-UV CD spectrum. Its hemolytic activity and cytotoxicity were measured by hemolysis and MTT assays, respectively. Surfactin formed spherical nanomicelles in distilled water and amorphous nanomicelles in PBS buffer . The hemolysis assay results indicated that HC50 of surfactin was 47 μM. Surfactin C-15 arrested growth of human cervix cancer HeLa cell line in a time- and dosage-dependent method, so that its IC50 at 16, 24, and 48h were 86.9, 73.1, and 50.2 μM, respectively.

    This study is of 92 patients who were treated for Stage III carcinoma of the cervix in the Henri Becquerel Centre. We have ruled out the 11 patients who refused to complete their treatment or who died before treatment started. The average age was 63 years. The Stage III cases were divided into 40 Stage III A and 41 Stage III B, with 10 who had urinary tract involvement. These were epidermoid carcinomata. The treatment was by external radiotherapy followed by superimposed radium therapy in 66 cases. 15 patients were treated by external radiotherapy alone. The lumboartic nodes were treated in the area that was irradiated in 5 patients. The actuarial figures for survival work out at 51 per cent at 5 years for Stage III A cases and 34 per cent for Stage III B cases. Pelvic recurrences were responsible for 87 per cent of the failures. In fact, in almost 87 per cent of the cases the area was not completely sterilised. The percentage of failures was higher in the group that had altered lymphograms. The prognosis was worst when the upper urinary tract was affected. All patients who had positive lymphograms or those that were suspicious of having lumboaortic nodes involved died. In the 15 patients who did not have added radium therapy there were 13 cases who were not sterilised and 1 that recurred at 13 months. In 32 per cent of cases the failures in the pelvis were associated with pathology in distant lymph nodes and/or with visceral metastases. We found 13 per cent of solitary metastases. Between 5 and 10 years the failure rate is 9 per cent with a level of 6.3 per cent of pelvic recurrences associated or not associated with metastases or even with complications. Our patients had 8 rectosigmoid complications of which 2 needed a diversion colostomy. There were 7 cases of cystitis after X-ray, in the majority of a benign nature, and 2 bony complications that recovered spontaneously.

    The objective of this paper was to define the effect of education on the early diagnosis of breast and cervix cancer on the women's attitudes and behaviors regarding participating in Cancer Early Diagnosis, Screening and Training Centers-CEDSTC screening programs. This semi-experimental study was completed with 342 women. The data were collected with forms "Champion's Health Belief Model Scale Breast Cancer-HBMSBC" and "Health Belief Model Scale for Cervical Cancer and the Pap Smear Test-HBMSCCPST." When the women's health beliefs before and after 6 months of the education about the early diagnosis of breast and cervical cancers are considered, it is seen that the HBMSBC subscales health motivation, breast self-examination (BSE), and evasion to mammography (MMG) decreased and BSE self-efficacy and MMG benefit attitudes increased and HBMSCCPST subscales pap smear benefit attitudes increased and evasion to pap smear attitude decreased (p < 0.05). Six months after the education, 28.4% of the women had undergone MMG, 69.9% had performed BSE, and 33.6% had undergone a pap smear test. Education regarding early diagnosis of breast and cervix cancer was found to have positive effects on the health behaviors of the women related to BSE, MMG, and pap smear tests. The women require professional education program for increasing their attitudes and behaviors for CEDSTC screening programs. We suggest regularly providing education to increase participation in early screening programs.

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

    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

    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. PMID:26388997

    Full Text Available Introduction: Carcinoma cervix is a leading cause of cancer in India. However, majority of the patients face a problem of not being able to complete the treatment. Aim: This study was an attempt to find out the important causes of this non-compliance to treatment in a rural Medical College Hospital where majority of the cancer cases are of cervical cancer. Results: Out of 144 patients studied over 2 years 88 cases could not complete the treatment. The study revealed that due old age 58.33% cases were defaulters, having many children at home meant a burden to 76.92% cases and 63.89% cases had a problem of not been able to travel a far distance of more than 100 km from home to hospital for treatment. Conclusion: These were the important factors of non-compliance and suggested more important than the issues of literacy and poor socio-economic status.

    In this study, we aimed at evaluating the distribution of HPV types and the expression of P53 and Ki-67 in cervix carcinomas of Mozambican women. Fourty-seven invasive carcinomas, 10 CIN III, and 10 normal cervix were studied. P53 and Ki-67 expression was examined immunohistochemically. HPV infection and HPV types were detected by PCR (GP5+/bio-GP6+) and enzyme-immunoassay, respectively. Expression of P53 and Ki-67 and detection of HPV were as follows: normal cervix--0%, 10%, and 0%, respectively; CIN III--10%, 0%, and 100%, respectively; invasive carcinomas--50%, 55.5%, and 70%, respectively. HPV 16 was identified in 54% of invasive carcinomas, HPV 31, 33, 35, and 45 in 23%, "unidentified" HPV in 19%, and HPV 18 in 4% of invasive carcinomas. No significant associations were observed between P53 expression, Ki-67 expression, and HPV infection. In conclusion, we observed a high frequency of HPV infection in CIN III lesions and invasive carcinomas from Mozambican women, with HPV 16 representing the most frequent viral type. HPV status was not related to P53 and Ki-67 expression. Both P53 and Ki-67 are associated with invasive cervix carcinomas, mainly of the squamous keratinizing histotype.

    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.

A baixa sensibilidade da citologia não a qualifica como exame de rastreamento para a detecção do HPV, nesse grupo de mulheres.PURPOSE: to verify the accuracy of uterine cervix cytology for HPV diagnosis, as compared to polymerase chain reaction (PCR in samples of women with HIV. METHODS: 158 patients who had undergone a first collection of material from the uterine cervix with Ayre's spatula for PCR were included in the study. Then, another collection with Ayre's spatula and brush for oncotic cytology was performed. Only 109 slides were reviewed, as 49 of them had already been destructed for have being filed for over two years. RESULTS: the prevalence of HPV was 11% in the cytological exam and 69.7% in the PCR. Age varied from 20 to 61 years old, median 35 years. The HIV contagious route was heterosexual in 91.8% of the cases, and 79.1% of the patients had had from one to five sexual partners along their lives. The most frequent complaint was pelvic mass (5.1%, and 75.3% of the women had looked for the service for a routine medical appointment. The categorical variable comparison was done through contingency tables, using the χ2 test with Yates's correction to compare the ratios. The Fisher's test was used when one of the expected rates was lower than five. In the comparison of diagnostic tests, sensitivity, specificity and similarity ratios have been calculated. Among the 76 patients with HPV, detected by PCR, only 12 had the diagnosis confirmed by cytology (sensitivity=15.8%, which on the other hand did not present any false-positive results (specificity=100%. Concerning the HPV presence, the cytological prediction for positive results was 100% and 33.3% for negative, when both results were compared. Among the 12 patients with HPV positive cytology, four (33.3% presented cervical intraepithelial neoplasia (OR=56; positive similarity

    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.

    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.

    Full Text Available Background: With advancements in imaging, wide variations in pelvic anatomy have been observed, thus raising doubts about adequate target volume coverage by conventional external radiotherapy fields based on bony landmarks. The present study evaluates the need for integrating computed tomography (CT-based planning in the treatment of carcinoma cervix. Aims: To estimate inadequacies in target volume coverage when using conventional planning based on bony landmarks. Materials and Methods: The study consisted of 50 patients. Target volume delineation was done on planning CT scans, according to the guidelines given in literature. The volume of target receiving 95% of prescribed dose (V95 was calculated after superimposing a conventional four field box on digitally reconstructed radiograph. The geographic miss with conventional four field box technique was compared with the CT-based target volume delineation. Results: In 48 out of 50 patients, the conventional four field box failed to encompass the target volume. The areas of miss were at the superior and lateral borders of the anterior-posterior fields, and the anterior border of the lateral fields. The median V95 for conventional fields marked with bony landmarks was only 89.4% as compared to 93% for target delineation based on CT contouring. Conclusions: Our study shows inadequate target volume coverage with conventional four field box technique. We recommend routine use of CT-based planning for treatment with radiotherapy in carcinoma cervix.

In such situation new, more effective, but less expensive organizational measures for prevention and early identification of oncological diseases should be developed. The recent epidemiological studies have convincingly shown that high-oncological-risk genital papilloma viral infection was certain risk factor of developing pre-cancer changes and cervical cancer. Detection of HPV regional epidemiological characteristics is extremely important for optimization of programs on diagnostics and prevention of cervix uteri cancer. The epidemiological and molecular-biological studies in Yakutia have detected more high infection rate in the female population than in male one. It was established that 11 high-oncological-risks genotypes of the virus circulating in the region with considerable prevalence of HPV Type 16. Since 2008 the program on vaccination against papilloma viral infection for girls and young women aged 10 to 25 years has been implemented in Yakutia Over six years, the number of vaccinated girls and women in Yakutsk reached 1093 persons. It has been the first experience in the Siberian and Far Eastern Federal Regions.

    Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Exposure to HPV is very common, and an estimated 65%-100% of sexually active adults are exposed to HPV in their lifetime. The majority of HPV infections are asymptomatic, but there is a 10% chance that individuals will develop a persistent infection and have an increased risk of developing a carcinoma. The International Agency for Research on Cancer has found that the following cancer sites have a strong causal relationship with HPV: cervix uteri, penis, vulva, vagina, anus and oropharynx, including the base of the tongue and the tonsils. However, studies of the aetiological role of HPV in colorectal and esophageal malignancies have conflicting results. The aim of this review was to organize recent evidence and issues about the association between HPV infection and gastrointestinal tumours with a focus on esophageal, colorectal and anal cancers. The ultimate goal was to highlight possible implications for prognosis and prevention. PMID:27672265

    Cervical cancer is one of the most common neoplastic diseases affecting women, with a combined world wide incidence of almost half a million new cases. Reduced DNA repair capacity (DRC) can render a high risk of developing many types of cancer; including cervical cancer. Polymorphisms in DNA repair genes may contribute the genetic instability and carcinogenesis. Smoking experience and use of oral contraceptives have been confirmed to be risk factors for cervical cancer. The purpose of the present study was, therefore to investigate APE-1 genotypes (Asp/Asp, Asp/Glu, Glu/Glu) with different histological subtypes in cases compared with controls. It has been observed that Asp/Glu with Glu/Glu genotypes that combined we observed statistically significant with protective effect for developing of cervix cancer (OR-0.51, 95% CI 0.31-0.83, p-0.006). The combined Asp/Glu with Glu/Glu genotypes who were using oral contraceptives were shown to be statistically significant with reduced risk of cervical cancer (OR-0.22 95% CI- 0.11-0.47, p-0.0002). It has been suggested that significantly correlation between HPV 16 and users of oral contraceptives in certain APE-1 genotypes with reduced risk in developing cervix cancer. In conclusion we observed statistical significant association with reduced risk of cervix cancer in APE-1 with different genotypes, though, on the other hand, in association between HPV type 18 and those having SCC, highly increased risk of cervical cancer was observed.

    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.

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.

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

    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.

Three patients had partial response (30%, CI, 1.7%-58.5%. Mean response duration was 198 days (range: 122-273 days. Four patients required red blood cell transfusions; three of them had grade II and one of them grade III nausea and vomiting Two had fever and neutropenia (one developed acute renal insufficiency, and there wee no treatment related mortalities. First-line chemotherapy with platinum and 5-FU for advanced recurrent cervical cancer is promising and deserves consideration for large phase III trials.

    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.

    Objective: to evaluate, by means of magnetic resonance imaging, the standardized field borders in radiotherapy for malignant neoplasm of uterine cervix, and to determine the role of this method in the reduction of possible planning errors related to the conventional technique. Materials and methods: magnetic resonance imaging studies for planning of treatment of 51 patients with uterine cervix cancer were retrospectively analyzed. The parameters assessed were the anterior and posterior field borders on sagittal section. Results: The anterior field border was inappropriate in 20 (39.2%) patients and geographic miss was observed in 37.3% of cases in the posterior border. The inappropriateness of both field borders did not correlate with clinical parameters such as patients' age, tumor staging, histological type and degree. Conclusion: the evaluation of standardized field borders with the use of magnetic resonance imaging has demonstrated high indices of inappropriateness of the lateral field borders, as well as the relevant role of magnetic resonance imaging in the radiotherapy planning for patients with uterine cervix cancer with a view to reduce the occurrence of geographic miss of the target volume.

    AK-2123, is a nitrotriazole with a potential to sensitize hypoxic tissue to radiation. Cancer of cervix in advanced stages are predominantly treated with radiation. These are the tumours which harbour a large hypoxic core. This is an Indian experience of the multicentric trial. Patients were randomized to control and AK-2123 arm. 49 patients were randomized to each group. Patients received external radiation with telecobalt to a dose of 50 Gy in five weeks. Those in the study arm received 600 mg/m2, on alternate days. The patients were further treated with intracavitory radiation a dose of 20 Gy. The total dose of 70 Gy was achieved. Patients in the study arm had a complete response of 71.43% (35 of 49) while only 21 of 49 (42.86%) responded in the control group. The overall survival at two years was 72.2% for the study group and 32.43% for control. Neuropathy, a drug related toxicity was transient except, in one patient, which has persisted. AK-2123, has shown significant radiation sensitizing potential.

    The aim of this report is to prevent a simple quality indicator (QI) that can be promptly used to evaluate the high-dose-rate (HDR) intracavitary brachytherapy for the treatment of cancer of the cervix, and if necessary, to correct applicators' geometry before starting the treatment. We selected 51 HDR intracavitary applications of brachytherapy of patients with carcinoma of the cervix treated with 60 mm uterine tandem and small Fletcher colpostat, according to the Manchester method (dose prescription on point A). A QI was defined as the ratio between the volume of 100% isodose curve of the study insertion and the volume of the 100% isodose curve of an insertion considered to be ideal. The data obtained were distributed in three groups: the group with tandem placement slippage (67,5%), a group with colpostat placement slippage (21,9%), and a third group, considered normal (10,6%). Each group showed particular characteristics (p < 0.0001). QI can be the best auxiliary method to establish the error tolerance (%) allowed for HDR intracavitary brachytherapy. (author)

    Full Text Available Abstract Background Human papillomavirus type 16 (HPV-16 infection is an important cause of cervical cancer, other anogenital cancers and, possibly, some oral and pharyngeal cancers. The association of HPV-16 with oesophageal and with prostate cancers has not been firmly established. Methods We analysed sera from 3,757 HIV seronegative black South Africans using an anti-HPV IgG enzyme-linked immunosorbent assay (ELISA. The subjects were recruited from 1995 to 2000 as part of an ongoing cancer case control study. Cases were patients with newly diagnosed cancers of the cervix (n = 946, other anogenital organs (n = 80, the oral cavity and pharynx (n = 102, the oesophagus (n = 369 or the prostate (n = 205. The comparison group consisted of 2,055 age and sex-matched patients randomly selected from the same data base, diagnosed at the same hospitals, but with a vascular disease or with a cancer unrelated to HPV infection. Subjects' sera were randomly and blindly allocated onto ELISA plates. Optical density (OD levels of anti-HPV-16 IgG of > 0.45 and ≥ 0.767 were taken to be cut-offs for negative, medium and high antibody levels. Results After adjustment for potential confounders, cancer types that showed a statistically significant association with increased anti-HPV-16 IgG antibody (Ab levels were cancer of the cervix (OR for medium Ab levels = 1.6, and for high = 2.4, p Conclusion If there is indeed an association between HPV-16 and oesophageal and possibly also some oral cavity and pharyngeal cancers, then emerging HPV vaccines may also reduce, at least in part, the incidence of these leading cancer types.

    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 multiyear 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 multistage 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.

    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.

    Small cell carcinoma of the uterine cervix accounts for 1-3% of all cervix cancers. It is an aggressive disease with a poor prognosis. To date, no effective treatment protocol has been determined. Surgery, radiotherapy, and chemotherapy have been used either alone or in combination. Recent data suggests that survival in patients with early staged small cell carcinoma of the cervix is better with surgery combined with chemo-radiotherapy. Here, we presented two patients with stage IB1 small cell carcinoma of the uterine cervix. For both patients, definitive surgery was performed with pelvic and para-aortic lymphadenectomy. Subsequently, they were treated with pelvic external radiotherapy and high-dose-rate intracavitary brachytherapy with concurrent cisplatin based chemotherapy. They were alive with no evidence of disease at 91 and 65 months, respectively.

    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

    Full Text Available Natalie Klag, Adam C Walter, Kristen M Sheely, Kelly J Manahan, John P Geisler Division of Gynecologic Oncology, Cancer Treatment Centers of America Newnan, Georgia, USA Background: New chemotherapy combinations are being tested for the treatment of women with advanced, persistent or recurrent cervical cancer. We sought to evaluate the cost effectiveness of some newer combination therapies in cervical cancer. Patients and methods: A cost effectiveness decision model was used to analyze Gynecologic Oncology Group 240. All regimens were modeled for seven cycles. The regimens studied are as follows: regimen 1, cisplatin/paclitaxel (CP; regimen 2, CP with bevacizumab (CP+B; regimen 3, paclitaxel/topotecan (PT; and regimen 4, PT with bevacizumab (PT+B. Overall survival, cost, and complications were studied. Sensitivity analyses were performed. Results: Mean chemotherapy costs over mean total costs for seven cycles of each follows: CP $571/$32,966; CP+B $61,671/$96,842; PT $9,211/$71,620; and PT+B $70,312/$109,211. Incremental cost-effectiveness ratio (ICER for CP+B was $133,559/quality adjusted life year (QALY. ICER for PT+B was $124,576/QALY. To achieve an incremental ICER for CP+B:CP of <$50,000/QALY gained, the mean overall survival has to increase from 1.1 years with CP to 3.5 years with CP+B. An ICER <$50,000/QALY for the other regimens would take a survival of >10 years for PT and 4.1 years for PT+B. Treating 1,000 women with cervical cancer with CP+B would cost almost double the cost of treating >18,000 women with ovarian cancer annually (carboplatin/paclitaxel. Conclusion: CP is the most cost effective regimen. A 12-month increase in overall survival will not even make the newer combinations cost effective. Currently, the use of bevacizumab is not sustainable at today's costs. Keywords: cervical cancer, chemotherapy, bevacizumab, cost-effectiveness

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

NCI, together with the National Library of Medicine (NLM), is developing a unique web-accessible database of the digitized cervix images to study the evolution of lesions related to cervical cancer. Tools are needed for automated analysis of the cervigram content to support cancer research. We present a multistage scheme for segmenting and labeling regions of anatomical interest within the cervigrams. In particular, we focus on the extraction of the cervix region and fine detection of the cervix boundary; specular reflection is eliminated as an important preprocessing step; in addition, the entrance to the endocervical canal (the "os"), is detected. Segmentation results are evaluated on three image sets of cervigrams that were manually labeled by NCI experts.

    Full Text Available Histopathological effects of cAMP analog (8-Chloro-cAMP, tamoxifen, and medroxyprogesterone, alone or combined, upon BALB/c mice uteri are reported. 8-Chloro-cAMP diminished uterine weight, but did not modify its histopathology or estral cycle significantly. Tamoxifen diminished uterine weight showing cystic hyperplasia and an estral cycle arrested at diestrus. Medroxyprogesterone increased uterine weight, caused a swelling of the endometrium and a pseudopregnancy estrus. When combined with 8-Chloro-cAMP, tamoxifen or medroxyprogesterone always had a predominant effect. We concluded that the effects of 8-Chloro-cAMP on mice uteri did not cause significant changes on its histopathology, but diminished its weight.

    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). Conclusion: MRI-morphologic features of PM infiltration appear to allow for prediction of tumour response during external beam radiotherapy and chemotherapy. A predominantly infiltrative tumour spread at the

    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.

    Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

    Procedures aimed at the treatment of precancerous lesions and ectopia on the uterine cervix are frequently linked to lesions of anatomical structures. The application of hyaluronic acid (Cicatridine vaginal ovules) promotes accelerated healing of the uterine cervix and acquisition of a normal shape in the uterine cervix canal. Local application of hyaluronic acid in the vagina following radiotherapy due to cancer in the uterine cervix or endometrium favourably affects the healing of post-irradiation lesions in the vagina and improves quality of life. Over 90% of patients responded positively to the application of hyaluronic acid in the form of a cream on dystrophic lesions in the vulva. Hyaluronic acid aids the healing process of post-procedural wounds in the uterine cervix, following radiotherapy applied due to cancer of the uterine cervix, endometrium and in vulvar dystrophy.

    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

    We investigated the cancer screening rates for five types of cancer (stomach, liver, colorectal, breast, and cervix uteri) using data from the Korean National Cancer Screening Survey (KNCSS), which is a nationwide, annual cross-sectional survey. The eligible study population included cancer-free men 40 years of age and older and women 30 years of age and older. The lifetime screening rate and screening rate with recommendation were calculated. The lifetime screening rates for gastric, liver, colorectal, breast, and cervical cancers were 77.9%, 69.9%, 65.8%, 82.9%, and 77.1%, respectively. The screening rates with recommendation were 70.9%, 21.5%, 44.7%, 70.9%, and 67.9%, respectively. The most common reason for all types of cancer was "no symptoms, " followed by "lack of time" and "fear of the examination procedure. " Efforts to facilitate participation in liver and colorectal cancer screening among Korean men and women are needed.

    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 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.

    Eight hundred and thirty five patients with a diagnosis of Stages I or II carcinoma of the cervix were treated from 2 January 1965 to 30 June 1971. The purpose of this study was to calculate the 5 year survival rates and to analyze the treatment failures according to the modality of treatment applied. Two series of Stages Ib and IIa patients were available; one group was treated with radiotherapy, and the other with radical hysterectomy and pelvic lymphadenectomy after previous intracavitary radiumtherapy. No statistically significant difference was found in the 5 year survival of both groups. Most Stage IIb patients were treated with radiotherapy. When residual tumor was found in the uterus of a patients who underwent radical surgery after intracavitary radiumtherapy it did not influence survival. On the other hand, the presence of metastatic pelvic lymph nodes after intracavitary radium treatment was related to a lowered survival rate. The number of severe injuries was higher in patients who were treated surgically. Recurrences developed within 5 years after completion of treatment in 10.8% of Stage Ib patients, 21.5% of Stage IIa patients, and 34.5% of Stage IIb patients. Ninety per cent of these recurrences appeared within 3 years after therapy.

    From January 1, 1947, through December 31, 1971, 219 patients with primary adenocarcinoma of the intact uterine cervix were treated at the M.D. Anderson Hospital and Tumor Institute. Two modes of therapy were primarily used, namely, irradiationtherapy alone and irradiation therapy plus operation. The 5 year survival resultsare 83.7 per cent for patients with Stage i disease, 48.0 per cent for patients with Stage ii disease, 29.2 per cent for patients with Stage iii disease, and 0.0 per cent for patients with Stage iv disease. The group with irradiation plus operation had a better over-all survival rate. In addition, the incidence of central and pelvic recurrent disease was remarkably lower (fourfold difference). The urologic and bowel complications are discussed. This review lends support for our practice of preoperative irradiation followed by simple (constructive) hysterectomy for selected patients eith adenocarcinoma of the uterine cervix.

    The number of long-term cancer survivors in the general population of the UK is substantial and increasing rapidly. Many cancer survivors have been treated with radiotherapy but the likely number of radiotherapy-related second cancers has not previously been estimated. We used estimates of the numbers of cancer survivors in the UK at the beginning of 2007, in conjunction with estimates of the relative risk of a second primary cancer associated with previous radiotherapy from the United States Surveillance Epidemiology and End Results (SEER) programme, to estimate the numbers of incident cancers in the UK in 2007 that were associated with radiotherapy for a previous cancer and that may have been caused by it. We estimated that 1,346 cases of cancer, or about 0.45% of the 298,000 new cancers registered in the UK in 2007, were associated with radiotherapy for a previous cancer. The largest numbers of radiotherapy-related second cancers were lung cancer (23.7% of the total), oesophageal cancer (13.3%), and female breast cancer (10.6%); 54% of radiotherapy-related second cancers were in individuals aged 75 or over. The highest percentages of second cancers related to radiotherapy were among survivors of Hodgkin's disease and cancers of the oral cavity and pharynx and cervix uteri; over 15% of second cancers among these survivors were associated with radiotherapy for the first cancer. These calculations, which involve a number of assumptions and approximations, provide a reasonable, if conservative, estimate of the fraction of incident cancers in the UK that are attributable to past radiation therapy.

    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.

    controle locorregional da doença na pelve.PURPOSE: to assess to what extent the surgical staging differs from the clinical staging among cases of advanced uterine cervix carcinoma, and also to assess the percentage of cases with positive para-aortic ganglia in this group of patients. METHODS: this is a descriptive prospective study in which 36 patients with histological diagnosis of uterine cervix carcinoma considered locally advanced were included (stages IB2, IIB, IIIA and B, and IVA. The cases were submitted to clinical staging, according to FIGO criteria. All patients were to be treated with neoadjuvant chemotherapy. Age ranged from 40 to 73 years, with a mean of 56.2±7.9. The procedure started with pelvic lymphadenectomy followed by para-aortic lymphadenectomy, in case the pelvic lymph nodes were positive on surgical examination. Examination of the abdominal cavity and lymphadenectomy were done either through laparotomy or laparoscopy, chosen at random. In each case, the clinical staging was compared to the surgical staging, considered the gold standard. RESULTS: in the clinical staging (CS, 7 cases were classified as IB2 (tumors larger than 4 cm, 22 cases as CSII and 7 cases as CSIII. The surgical assessment changed the clinical staging as follows: the stage was decreased in six cases, and increased in 13. There was agreement only in 18 cases (50%. The para-aortic lymph nodes were affected in six cases. CONCLUSIONS: clinical staging of locally advanced uterine cervix carcinoma is incorrect in most of the cases. Such inconsistency may lead to excessive treatment in some cases, but about one fourth of the patients with positive para-aortic ganglia would not be adequately treated with the current standard treatment radiotherapy with chemosensitization, which aims at the local regional control of the pelvic disease.

    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.

    Full Text Available Background: This observational study was aimed to determine the frequency of existence of sero-positivity for human immunodeficiency virus (HIV infection among women of age between 25 to 75 years with invasive cervical carcinoma and to decide whether HIV testing should be included as part of the initial routine work-up of cervical cancer patients. Methods: Histologically proven 120 cases of invasive carcinoma cervix, who came for treatment between 2009-2013, in the department of radiotherapy, after counselling gave consent were investigated for HIV by immunochromatography based rapid test. Results: Out of 120 patients investigated, reports revealed that only two patients (1.67% were HIV seropositive. Both of these patients were already HIV seropositive and on gynaecological screening were found to have malignancy of cervix. No patient of diagnosed carcinoma cervix was found seropositive for HIV. Most patients (106/120 were above 40 years of age, from rural background (92/120 and housewives (80/120. Only 15% (18/120 were smokers. 95.8% (115/120 were of stage II and III. None presented with metastasis. Most common pathology was moderately differentiated carcinoma, in 76 patients (63.3%. Conclusion: Screening for HIV, as part of the initial work up for cervical cancer is not necessary in countries with limited resources and low HIV prevalence.

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

    Full Text Available BACKGROUND: The Gambia Hepatitis Intervention Study (GHIS was designed as a randomised control trial of infant hepatitis B vaccination applied to public health policy, with the main goal of preventing primary liver cancer later in adult life in The Gambia. 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.

    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.

    Full Text Available BACKGROUND: Tumor regression parameters and time factor during external radiotherapy (EXTRT are of paramount importance. AIMS: To quantify the parameters of tumor regression and time factor during EXTRT in cancer cervix. SETTINGS AND DESIGN: Patients, treated solely with radiotherapy and enrolled for other prospective studies having weekly tumor regressions recorded were considered. MATERIALS AND METHODS: Seventy-seven patients received 50Gy of EXTRT followed by intracavitary brachytherapy. Loco-regional regressions were assessed clinically and regression fraction (RF was represented as RF = c + a1D + a2D2- a3T, with c, D and T as constant, cumulative EXTRT dose and treatment time respectively. STATISTICAL ANALYSIS USED: Step wise linear regression was performed for RF. Scatter plots were fitted using linear-quadratic fit. RESULTS: Coefficients of parameters D, D2 and T were computed for various dose intervals, namely 0-20 Gy, 0-30 Gy, 0-40 Gy and 0-50 Gy. At 0-20 Gy and 0-30 Gy, only the coefficient of D2 was significant (P < 0.001, while both D2 and T turned significant (P < 0.001 at 0-40 Gy. For the entire range of 0-50 Gy, all the coefficients of D, D2 and T showed significance, leading to an estimate of 26 Gy for a1/a2 and 0.96 Gy/day for a3/a1. CONCLUSIONS: As with a/β and g/a of post-irradiation cell survival curves, a1/a2 and a3/a1 represents the cumulative effect of various radiobiological factors influencing clinical regression of tumor during the course of EXTRT. The dynamic changes in the coefficients of D, D2sub and T, indicate their relative importance during various phases of EXTRT.

    An 18-year-old phenotypic male presented with an irreducible left inguinal mass, gynecomastia, and hypospadias. This mass on exploration was found to be a nonfunctional uterus with ipsilateral ovary and was excised. Further investigation confirmed the presence of a contralateral testis and a genotype of 46, XX. This confirmed the diagnosis of ovotesticular disorder of sexual differentiation (formerly true hermaphroditism) with obstructed hernia uteri inguinalis. The patient was raised as a male. Subcutaneous mastectomy for gynecomastia and neourethra construction with full thickness skin graft for hypospadias were performed. Hernia uteri inguinalis is rarely seen in this condition with only 2 cases being reported worldwide thus far, including our case.

    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.

    Tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) has high affinity for matrix metalloproteinase-2 (MMP-2). Few studies simultaneously investigate their implication in prognosis of patients with cervical cancer. We used reverse transcription-polymerase chain reaction and immunohistochemical method for cervical tissues and microarrays to investigate the association among TIMP-2, MMP-2, clinicopathological parameters, and prognosis of patients with cancer. Our results showed that cancer tissues exhibited less TIMP-2 expression and patients with pelvic lymph node metastasis had less TIMP-2 expression. Positive TIMP-2 constellated with negative MMP-2 indicated lower recurrence probability and better overall survival. The protective effect of TIMP-2 expression may overcome the adverse effect of MMP-2 expression in terms of disease-free interval and overall survival while neither TIMP-2 nor MMP-2 alone can be used to predict outcome. We suggest that following patients other than those with positive TIMP-2 and negative MMP-2 expression more closely and intensely may improve their prognosis.

    Objective : To explore the expressions of RhoC and ROCK Ⅰ in cervical intraepithelial neoplasia ( CIN ) and cervical cancer as well as their relationship with the genesis of cervical cancer. Methods : The expressions of RhoC and ROCK Ⅰ in cervical cancers( n = 27 ) , CIN Ⅲ( n = 28 ) , CIN Ⅱ ( n = 28 ) , CIN Ⅰ ( n = 25 )and chronic inflammations( n = 28 )were detected by immunohistochemistry. Results : The expressions of RhoC and ROCK Ⅰ in CIN Ⅱ ,CIN Ⅲand cervical cancer were significantly higher than that of CIN Ⅰ and chronic inflammation ( P < 0. 01 ). The severer the cervical lesion was, the higher expression level of Rhoc and ROCK Ⅰ .And the expression level of RhoC was of positive correlation with that of ROCK Ⅰ in CIN Ⅱ and above stages( rs = 0. 605 .

    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 < 0.05). 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). Persistent cervical FDG uptake in {sup 18}F-FDG PET/CT after CCRT for cervical cancer may be caused by residual tumor or post

    Full Text Available Cervical agenesis or dysgenesis is an extremely rare congenital anomaly. Patients with congenital absence of the cervix present with primary amenorrhea and infertility. Though it poses a diagnostic challenge to the clinician, correct diagnosis prior to surgery is possible with the help of ultrasound. Early diagnosis offers significant advantages in patient care and effective presurgical planning. This case report reviews two cases of cervical agenesis diagnosed with the help of ultrasound and later confirmed with the help of MRI. Ultrasonography is the modality of choice to define the internal genital anatomy and helps us to classify the level of obstruction or aplasia in obstructive uterine anomalies.

    The GYN GEC-ESTRO working group issued three parts of recommendations and highlighted the pivotal role of MRI for the successful implementation of 3D image-based cervical cancer brachytherapy (BT). The main advantage of MRI as an imaging modality is its superior soft tissue depiction quality. To exploit the full potential of MRI for the better ability of the radiation oncologist to make the appropriate choice for the BT application technique and to accurately define the target volumes and the organs at risk, certain MR imaging criteria have to be fulfilled. Technical requirements, patient preparation, as well as image acquisition protocols have to be tailored to the needs of 3D image-based BT. The present recommendation is focused on the general principles of MR imaging for 3D image-based BT. Methods and parameters have been developed and progressively validated from clinical experience from different institutions (IGR, Universities of Vienna, Leuven, Aarhus and Ljubljana) and successfully applied during expert meetings, contouring workshops, as well as within clinical and interobserver studies. It is useful to perform pelvic MRI scanning prior to radiotherapy ("Pre-RT-MRI examination") and at the time of BT ("BT MRI examination") with one MR imager. Both low and high-field imagers, as well as both open and close magnet configurations conform to the requirements of 3D image-based cervical cancer BT. Multiplanar (transversal, sagittal, coronal and oblique image orientation) T2-weighted images obtained with pelvic surface coils are considered as the golden standard for visualisation of the tumour and the critical organs. The use of complementary MRI sequences (e.g. contrast-enhanced T1-weighted or 3D isotropic MRI sequences) is optional. Patient preparation has to be adapted to the needs of BT intervention and MR imaging. It is recommended to visualise and interpret the MR images on dedicated DICOM-viewer workstations, which should also assist the contouring

    There are five population-based cancer registries in Thailand in different regions of the country. Four of them (Chiang Mai, Khon Kaen, Bangkok, and Songkhla) have been operating since 1988 and the other (Lampang) since the early 1990s. These registries have published regular 3-year cancer incidence reports since the first in 1993 for the period 1989-1991. The objective of this article is to summarize the figures of cancer incidence in Thailand during 1995-1997. The population of Thailand in 1996, at the middle of the period, was 27 million males and 27.5 million females. Information of cancer cases residing in the five provinces was collected and abstracted from different sources. Age-standardized incidence rate (ASR) of cancer in males and females was calculated for each registry and that for the whole country was estimated using the five registries as representatives for the four geographical regions of Thailand. The estimated number of new cancer cases in 1996 for the whole country was 35,539 men and 38,476 women and the ASRs were 149.2 and 125.0 per 10(5) population in men and women respectively. Cancer incidences greatly differed from region to region. Lung cancer was the commonest in Chiang Mai and Lampang in the Northern region in both sexes. The incidence of liver cancer in Khon Kaen in the Northeastern region outnumbered all the others in both sexes; cholangiocarcinoma was the major type of liver cancer. In Bangkok, lung cancer was the most important cancer in males and breast cancer was in females. Though it was lung and cervix uteri cancer that ranked the first in men and women in Songkhla, the rate of oral and pharyngeal cancer was exceptionally higher than in other registries. The geographical variability in cancer patterns in Thailand reflects exposure of the population to different risk factors unique to the different regions. In the study as a whole, there are some methodological weak points in estimating the ASRs and number of cancer cases for the

    Full Text Available Abstract Background Cervical cancer and infection with human immunodeficiency virus (HIV are both important public health problems in South Africa (SA. The aim of this study was to determine the prevalence of cervical squamous intraepithelial lesions (SILs, high-risk human papillomavirus (HR-HPV, HPV viral load and HPV genotypes in HIV positive women initiating anti-retroviral (ARV therapy. Methods A cross-sectional survey was conducted at an anti-retroviral (ARV treatment clinic in Cape Town, SA in 2007. Cervical specimens were taken for cytological analysis and HPV testing. The Digene Hybrid Capture 2 (HC2 test was used to detect HR-HPV. Relative light units (RLU were used as a measure of HPV viral load. HPV types were determined using the Roche Linear Array HPV Genotyping test. Crude associations with abnormal cytology were tested and multiple logistic regression was used to determine independent risk factors for abnormal cytology. Results The median age of the 109 participants was 31 years, the median CD4 count was 125/mm3, 66.3% had an abnormal Pap smear, the HR-HPV prevalence was 78.9% (Digene, the median HPV viral load was 181.1 RLU (HC2 positive samples only and 78.4% had multiple genotypes. Among women with abnormal smears the most prevalent HR-HPV types were HPV types 16, 58 and 51, all with a prevalence of 28.5%. On univariate analysis HR-HPV, multiple HPV types and HPV viral load were significantly associated with the presence of low and high-grade SILs (LSIL/HSIL. The multivariate logistic regression showed that HPV viral load was associated with an increased odds of LSIL/HSIL, odds ratio of 10.7 (95% CI 2.0 – 57.7 for those that were HC2 positive and had a viral load of ≤ 181.1 RLU (the median HPV viral load, and 33.8 (95% CI 6.4 – 178.9 for those that were HC2 positive with a HPV viral load > 181.1 RLU. Conclusion Women initiating ARVs have a high prevalence of abnormal Pap smears and HR-HPV. Our results underscore the need

    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

    Since 10 years, the combination of chemoradiotherapy has become a standard of treatment of the advanced localized cervical cancer. Two systematic reviews of the literature (including the results of the different clinical trials) have already been published. The aim of this article is to present the results of the recent meta-analysis based on individual patient data and to discuss the perspectives. This meta-analysis was rigorously designed: trials selected had the same control arm with the same radiotherapy without concomitant chemotherapy, the definition of the primary outcome (overall survival) was homogeneous and analysis was made in intent to treat. The results confirm the advantage in overall survival in favor of the chemoradiotherapy with an absolute 5-year overall survival benefit of 6% (60-66%) and 8% of 5-year disease-free survival (50-58%). Interestingly, even if cisplatin seems to be the most active drug, a significant advantage is also observed with no platinum chemotherapy. A polychemotherapy is not more active than a mono chemotherapy and there was a suggestion of a difference in the size of the survival benefit with tumor stage. Larger benefits were seen for the few trials in which additional chemotherapy was administered after chemoradiotherapy, but results have to be confirmed by other clinical trials. Late toxicity was not well evaluated and a long-term follow-up of the patients is important to assess the real incidence of long-term side effects of the chemoradiotherapy and the impact on quality of life. New strategies combining new chemotherapy protocols or targeted therapy with radiation are promising but have to be evaluated in comparative clinical trials before use in routine. (authors)

    Traditionally, prescription and treatment planning in intracavitary brachytherapy for cervix cancer have used either reference points (mainly points A and B) or reference isodoses (60 Gy according to ICRU recommendations) to report doses to the target volume. Doses to critical organs were reported at bladder and rectum ICRU points. This practice has been supported by a long-standing clinical experience that has yielded an acceptable therapeutic ratio. The recent development of imaging has contributed to the improvement in target and organs at risk knowledge. In 2005 and 2006, the European group of brachytherapy -European Society for therapeutic radiology and oncology (GEC-E.S.T.R.O.) recommendations publications on 3-D based image brachytherapy have defined the different volumes of interest. These recommendations have been validated with intercomparison delineation studies. With the concomitant development of remote after-loading projectors, provided with miniaturized sources, it is now possible to plan radiation doses by adjusting dwell positions and relative dwell time values. These procedures allow better coverage of the targets while sparing O.A.R.. The recent literature data evidence a significant improvement in local control with no increase in complications. Further studies are needed to better define the dose recommended in both tumour and organs at risk. This is one of the goals of the European study on MRI-guided brachytherapy in locally advanced cervical cancer (E.M.B.R.A.C.E.) protocol (meaning of acronym: an international study on MRI-guided brachytherapy in locally advanced cervical cancer).

    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 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.

    Full Text Available Background and objectives: Cervical cancer is a disease with high degree of morbidity and mortality, but has early detection by performing screening test which allows healing. This study aimed to evaluate the knowledge regarding prevention of Cervical Cancer among women in a Basic Health Unit in Minas Gerais. Methods: This is a study descriptive with approach qualitative with 44 women. Was used as the data collection instrument of a semistructured script consisting of subjective questions. Data were collected between March April 2014. Results: The women had age of 40-57 years old, 33 (75% were married, 43(97,73% had children, 20 (45,45% had incomplete primary education, 36 (81,82% were responsible for all financial income of the family and lived with up to the minimum wage. As for the Pap smear, considered important, however showed little clarity as to the meaning of prevention. Performed the test as means of prevention and early diagnosis of Cervical Cancer. Among women who did not perform the preventive the cause was discouragement. Conclusion: We conclude that although the Pap smear be offered for free, there is still women who do not have adequate knowledge about the same and not makes periodically, fitting to health services intensify health education programs to seeking to raise awareness about the importance of regular practice of the Pap smear.

    The second part of the GYN GEC ESTRO working group recommendations is focused on 3D dose-volume parameters for brachytherapy of cervical carcinoma. Methods and parameters have been developed and validated from dosimetric, imaging and clinical experience from different institutions (University of Vienna, IGR Paris, University of Leuven). Cumulative dose volume histograms (DVH) are recommended for evaluation of the complex dose heterogeneity. DVH parameters for GTV, HR CTV and IR CTV are the minimum dose delivered to 90 and 100% of the respective volume: D90, D100. The volume, which is enclosed by 150 or 200% of the prescribed dose (V150, V200), is recommended for overall assessment of high dose volumes. V100 is recommended for quality assessment only within a given treatment schedule. For Organs at Risk (OAR) the minimum dose in the most irradiated tissue volume is recommended for reporting: 0.1, 1, and 2 cm3; optional 5 and 10 cm3. Underlying assumptions are: full dose of external beam therapy in the volume of interest, identical location during fractionated brachytherapy, contiguous volumes and contouring of organ walls for >2 cm3. Dose values are reported as absorbed dose and also taking into account different dose rates. The linear-quadratic radiobiological model-equivalent dose (EQD2)-is applied for brachytherapy and is also used for calculating dose from external beam therapy. This formalism allows systematic assessment within one patient, one centre and comparison between different centres with analysis of dose volume relations for GTV, CTV, and OAR. Recommendations for the transition period from traditional to 3D image-based cervix cancer brachytherapy are formulated. Supplementary data (available in the electronic version of this paper) deals with aspects of 3D imaging, radiation physics, radiation biology, dose at reference points and dimensions and volumes for the GTV and CTV (adding to [Haie-Meder C, Pötter R, Van Limbergen E et al.

    The L-Arginine-Nitric Oxide Synthase-Nitric Oxide (L-Arg-NOS-NO) system exerts a pivotal role in the maintenance of uterine quiescence during pregnancy, whereas Homocysteine (Hcy) promotes uterine contractility. The aim of this study was to test the in vitro effects of L-Arg on spontaneous and Hcy-induced contractions of uteri excised from pregnant bitches. 104 strips cut from pregnant uteri were mounted in an organ bath. 40 out of 104 strips (16 from mid-gestation uteri and 24 from close to term uteri, respectively) were exposed to cumulative doses of L-Arg; 40 strips (16 from mid-gestation-uteri and 24 from close to term-uteri, respectively) were exposed to N-nitro-L-arginine methyl ester (L-NAME), a NOS antagonist; the remaining 24 strips (from close-to-term uteri) were first exposed to a single dose of Hcy and then to increasing doses of L-Arg. L-Arg showed no effects on spontaneous contractility both in mid-gestation- and close to term-uterine strips, whereas it promoted a relaxant effect on Hcy-induced contractility. On the contrary, L-NAME increased amplitude of contraction both in mid-gestation and close to term strips. These findings suggest that the L-Arg-NO system is present in the uterus of pregnant bitches and that Hcy is able to modulate its actions. Further investigation of this system may provide the basis of future obstetrical therapies in bitches.

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.

    Skeletal metastasis in carcinoma cervix occurs in about 0.8-23% of cases. These lesions are usually radiographically lytic. Very few cases of metastases to the skull have been identiifed, about 5 cases to the best of our knowledge. We present a case of adenosquamous cell carcinoma of cervix with fat attenuating skull metastases in a 38-year-old lady that is not reported till date. The lesion was lytic, expansile and with negative attenuation of -15 to -30 Hounsifeld units corresponding to fat.Metastases must be included in the differentials of scalp lesions. A history of recent onset of swelling and associated lytic areas in calvarium on contrast enhanced computed tomography with multiplicity can give a clue to metastatic nature of disease.

    In order to evaluate the role of cytokines in the development of polymodal local and distant effects in patients with stages I-IV cervical cancer, the following parameters were measured: serum concentrations of TNF-α, IFN-γ, IL-1β, IL-6, and IL-10; levels of malondialdehyde, activities of catalase, superoxide dismutase, glutathione reductase, and glutathione-S-reductase in the plasma, erythrocyte, and cervix uteri homogenate. The expression of p53, Bcl-2, VEGF, and Ki-67 in tumor tissue was evaluated. High levels of malondialdehyde in tumor tissue and erythrocyte were paralleled by low levels of superoxide dismutase and catalase and high activities of glutathiones. Medium correlations between Ki-67, Bcl-2, and p53 and the levels of IL-6, IL-10, and TNF-α at stages Ib-IIa were detected. The results indicated that the progress of cervical cancer was associated with the neoplasm integration in the host homeostasis by using the regional and systemic cytokine functions. These effects, amplifying the biological potential of the tumor, were the most significant at stages Ib-IIa.

    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.

    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

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

    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

    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.

  13. 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.

    We investigated the function and expression of voltage-gated Na(+) channels (VGSC) in the uteri of nonpregnant rats using organ bath techniques, intracellular [Ca(2+)] fluorescence measurements, and RT-PCR. In longitudinally arranged whole-tissue uterine strips, veratridine, a VGSC activator, caused the rapid appearance of phasic contractions of irregular frequency and amplitude. After 50-60 min in the continuous presence of veratridine, rhythmic contractions of very regular frequency and slightly increasing amplitude occurred and were sustained for up to 12 h. Both the early and late components of the contractile response to veratridine were inhibited in a concentration-dependent manner by tetrodotoxin (TTX). In small strips dissected from the uterine longitudinal smooth muscle layer and loaded with Fura-2, veratridine also caused rhythmic contractions, accompanied by transient increases in [Ca(2+)](i), which were abolished by treatment with 0.1 microM TTX. Using end-point and real-time quantitative RT-PCR, we detected the presence of the VGSC alpha subunits Scn2a1, Scn3a, Scn5a, and Scn8a in the cDNA from longitudinal muscle. The mRNAs of the auxiliary beta subunits Scbn1b, Scbn2b, Scbn4b, and traces of Scn3b were also present. These data show for the first time that Scn2a1, Scn3a, Scn5a, and Scn8a, as well as all VGSC beta subunits are expressed in the longitudinal smooth muscle layer of the rat myometrium. In addition, our data show that TTX-sensitive VGSC are able to mediate phasic contractions maintained over long periods of time in the uteri of nonpregnant rats.

    Full Text Available To establish the role of co-overexpression of bcl-2 and c-myc protooncogenes in uterine cervix carcinogenesis, we examined 138 tissue samples of low grade cervical squamous intraepithelial lesions (SIL, high grade SIL, portio vaginalis uteri (PVU carcinoma in situ and PVU carcinoma invasive, stage IA-IIA (study group and 36 samples without SIL or malignancy (control group. The expression of bcl-2 and c-myc was detected immunohistochemically using a monoclonal antibody. Fisher’s exact test (P<0.05 was used to assess statistical significance. Overexpression of bcl-2 was found to increase in direct relation to the grade of the cervical lesions. High sensitivity was of great diagnostic significance for the detection of these types of changes in the uterine cervix. On the basis of high predictive values it can be said that in patients with bcl-2 overexpression there is a great possibility that they have premalignant or malignant changes in the uterine cervix. Co-overexpression of bcl-2 and c-myc oncogenes was found only in patients with PVU invasive carcinoma (6/26-23.0%. Statistically significant difference was not found in the frequency of co-overexpression in patients with PVU invasive carcinoma in relation to the control group (Fisher’s test; P=0.064. The method's sensitivity of determining these oncogenes with the aim of detecting PVU invasive carcinoma was 23%, while specificity was 72.2%. On the basis of high predictive values (100%, speaking in statistical terms, it can be concluded that all patients with co-overexpression of bcl-2 and c-myc oncogenes will have PVU invasive carcinoma. We confirmed in our research that co-overexpression of bcl-2 and c-myc oncogenes was increased only in PVU invasive carcinoma. However, a more extensive series of samples and additional tests are required to establish the prognostic significance of bcl-2 and c-myc co-overexpression in cervical carcinogenesis.

    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.

    Massive local eosinophilia of 100 or more eosinophils per high power field was found in 3.2% cases of invasive carcinoma of the cervix. The prevalence, length of history before presentation to surgery and histological features were similar in patients from Great Britain and Malawi, but in both populations the mean age at diagnosis was lower than in patients with cervical carcinomas without tissue eosinophilia. In some of the tumours, the malignant cells were very difficult to find because of the eosinophil infiltrate, and misinterpretation as an inflammatory lesion was possible. In the absence of circulating eosinophilia, cervical carcinomas with massive eosinophilia were found to have a better prognosis than tumours without. Five patients had circulating eosinophilia as well as local tumour eosinophil infiltration, and each of them had extensive tumour spread.

    Full Text Available Definitive cytomorphologic diagnosis of small cell carcinoma of the uterine cervix is possible but can be challenging in routine cervicovaginal cancer screening specimens. Several small series of reported cases of cervical small cell carcinoma have shown this uncommon malignancy to represent fewer than 2% of all invasive cervical cancers. This tumor type is associated with poor prognosis and rapid disease progression and can develop to an advanced stage in the interval between screening visits. Only rare case reports of small cell carcinoma arising in gravid cervices are known. In the current case a 29-year-old, gravida 6, para 2, pregnant (10-week gestation female presented with postcoital bleeding. A definitive diagnosis of small cell carcinoma of the cervix was made possible by liquid based Pap testing with ancillary cell block preparation allowing for immunocytochemical characterization of the lesional cell population.

    The aim of this study was to localize and evaluate the role of Toll-like receptor 2 (TLR2) in the endometrium and cervix of bitches at different stages of the oestrous cycle and in bitches with pyometra. Sixty-seven nulliparous dogs, ranging in age from 1 to 13 years, were allocated amongst five groups (pro-oestrus; n = 7, oestrus; n = 10, dioestrus; n = 16, anoestrus; n = 11, pyometra; n = 23). Blood samples were collected for the measurement of progesterone concentration. The mean progesterone concentration was analysed as a parameter for validating the stage of the oestrous cycle in bitches. Tissues collected from uterine horn and cervix were fixed in 4% paraformaldehyde for immunohistochemical examination of TLR2. The expression of TLR2 was assessed semi-quantitatively. No pathological changes were found in the uterine samples of healthy dogs. In bitches with pyometra, the glandular epithelium expressed TLR2 more intensely than the surface epithelium. The expression of TLR2 in the glandular epithelium was also significantly higher in healthy dogs at oestrus, dioestrus and dogs with pyometra compared with anoestrous dogs (p < 0.01). The expression of TLR2 in the stroma was not observed in the group of healthy dogs at all stages. The surface epithelium of cervix in dogs with pyometra expressed TLR2 significantly more intensely than did the stoma, whereas the expression of TLR2 during oestrus and dioestrus was absent in the stroma of cervix. This study provides the first report of immunohistochemical localization of TLR2 in the canine reproductive tract. In the present study, TLR2 was expressed in endometrial epithelium but was absent in the endometrial stroma of healthy dogs at all oestrous cycle stages. These findings suggest differential expression of TLR in endometrial cells. On the other hand, the lack of TLR2 in the stroma of healthy uteri of dogs may predispose to infection from the invading pathogens once the epithelial cells have been destroyed by the

    Full Text Available This study identifies the period and cohort effects on the decreasing mortality trend of cancer of the uterine cervix and of the uterus, part unspecified, in the state of Minas Gerais, Brazil, during the period 1980-2005. 11,243 cases were included. A non-parametric method was used to calculate Z statistics and p-values. The cohorts were assessed one by one and also in blocks of three, so as to allow for a larger number of comparisons to be made. Greater than expected mortality reduction was observed for the cohort blocks of women born in 1913-1920; 1927-1936; 1937-1946; 1949-1956; 1963-1970; and 1969-1976. For the 1901-1908 and 1921-1928 cohort blocks a smaller than expected mortality decrease was found. As for period effect, we found a greater than expected reduction for the 2000-2001 period, in comparison with the previous one. The study suggests the existence of a significant cohort effect on mortality due to cancer of the uterine cervix in the study population, and such results have been placed in their social and political contexts.Buscou-se identificar os efeitos período e coorte na tendência de mortalidade por câncer de colo de útero e útero porção não especificada, no Estado de Minas Gerais, Brasil, no período de 1980-2005.

    Cervical cancer is one of the most common neoplastic diseases affecting women, with a worldwide incidence of almost half a million cases. A history of smoking and use of oral contraceptives have been confirmed to be risk factors for cervical cancer. Genetic susceptibility and immune response, especially impaired cellular immune response, may well be related to the development of cervical cancer. NBS1 is one of the key proteins participating in the recognition and repair of double-strand breaks that may lead to genomic instability and cancer if unrepaired. The objective of the present study was therefore to investigate NBS1 Glu185Gln gene polymorphisms and the risk of cervix cancer in a northern Indian population. We found that passive smokers having particular NBS1 genotypes (Glu/Gln, Gln/Gln or Glu/Gln + Gln/Gln)have an increased risk of developing cervix cancer (OR 5.21, p=0.000001; OR 4.60, p=0.001; OR 5.10, p=0.0000009, respectively).The risk was increased 2.4-fold in oral contraceptive users with a Glu/Gln genotype. We conclude that the risk of cervical cancer is increased in passive smokers and in users of oral contraceptives with certain NBS1 genotypes.

    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

    In the present study, an attempt was made to identify genes involved in radiation response in cervix carcinoma. Differential display technique was used to study the expression profiles of tumour biopsy samples obtained from patients, responding and not responding to treatment. The samples were obtained prior to radiotherapy and subsequent to treatment with Tele-radiation at 10 Gray (Gy). One of the differentially expressed cDNAs, when sequenced was identified to be CDC27. Immuno-histochemical analysis of pre- and post-treated tumour samples from fifteen patients showed the downregulation of expression of CDC27 protein in seven patients. Down-regulation was associated with poorer response to radiotherapy. Cervical cancer cell lines SiHa and C33A were irradiated and their nuclei were stained for expression of CDC27 and analyzed using fluorescent-activated cell sorting (FACS). Down-regulation of CDC27 protein in the irradiated SiHa cell line was associated with greater survival fraction, compared to the irradiated C33A cell line, which had only slight fall in the level of CDC27 protein. This is the first study to suggest a role for CDC27 in radiation response. However, a larger cohort is needed to further confirm the value of CDC27 protein as a predictive marker, for radiation response in 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.

    Full Text Available AIM: Aim of our study to analyze the prevalence of premalignant lesion based on Pap smear and liquid based cytology in patients of bad cervix. 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

    Invasive carcinoma found after simple hysterectomy for several causes is an increasing clinical condition. That situation results in the necessity for further therapy: re-operation or radiotherapy. The purpose of this review is to analyze our results with postoperative radiotherapy for these patients. In 1998, 59 patients were submitted to postoperative radiotherapy at the Oncology Hospital, Medical Cancer Center for invasive cervical cancer found after simple hysterectomy for several causes. All patients had postoperative radiotherapy, the dose depended of the magnitude of residual disease after surgery (range 10-80 Gy). After surgery 27 patients had gross residual disease; and no residual disease or microscopic disease was present in 32 patients. Three years overall survival rate was 59% for the whole group. With the results of the univariate analysis, prognostic factors found that significantly affect disease free survival were interval between hysterectomy and radiotherapy of more than 6 months, radiotherapy dose less than 50 Grays and histology. With multivariate analysis only presence of gross residual disease affect significantly disease free survival p = 0.0000. Postoperative radiotherapy results in patients with invasor cervical cancer incidentally found in hysterectomy specimens with minimal residual disease are excellent. However with the presence of more extensive residual disease the results in disease free survival are worse than those obtained in patients with similar stages who had not been treated with hysterectomy. A well established diagnostic procedure must be done in all patients candidates to simple hysterectomy.

    Optical histopathology is fast emerging as a potential tool in cancer diagnosis. Fresh tissues in saline are ideal samples for optical histopathology. However, evaluation of suitability of ex vivo handled tissues is necessitated because of severe constraints in sample procurement, handling, and other associated problems with fresh tissues. Among these methods, formalin-fixed samples are shown to be suitable for optical histopathology. However, it is necessary to further evaluate this method from the point of view discriminating tissues with minute biochemical variations. A pilot Raman and Fourier transform infrared (FTIR) microspectroscopic studies of formalin-fixed tissues normal, malignant, and after-2-fractions of radiotherapy from the same malignant cervix subjects were carried out, with an aim to explore the feasibility of discriminating these tissues, especially the tissues after-2-fractions of radiotherapy from other two groups. Raman and FTIR spectra exhibit large differences for normal and malignant tissues and subtle differences are seen between malignant and after-2-fractions of radiotherapy tissues. Spectral data were analyzed by principal component analysis (PCA) and it provided good discrimination of normal and malignant tissues. PCA of data of three tissues, normal, malignant, and 2-fractions after radiotherapy, gave two clusters corresponding to normal and malignant + after-2-fractions of radiotherapy tissues. A second step of PCA was required to achieve discrimination between malignant and after-2-fractions of radiotherapy tissues. Hence, this study not only further supports the use of formalin-fixed tissues in optical histopathology, especially from Raman spectroscopy point of view, it also indicates feasibility of discriminating tissues with minute biochemical differences such as malignant and after-2-fractions of radiotherapy.

    Full Text Available Aim: To report the outcome of carcinoma cervix patients treated radically by external beam radiotherapy and high dose rate intracavitary radiotherapy. Material and Methods: From January 2005 to December 2006, a total of 709 newly diagnosed cases of carcinoma cervix were reported in our department. All cases were staged according to the International Federation of Gynecologist and Oncologist staging system. Out of 709 cases, 342 completed radical radiotherapy and were retrospectively analyzed for the presence of local residual disease, local recurrence, distant metastases, radiation reaction, and disease free survival. Results: There were 11(3.22%, 82(23.98%, 232(67.83%, and 17(4.97% patients in stages I, II, III, and IV, respectively. The median follow up time for all patients was 36 months (range 3 -54 months. The overall treatment time (OTT ranged from 52 to 69 days (median 58 days. The 3 year disease free survival rate was 81.8%, 70.7%, 40.08%, and 11.76% for stages I, II, III, and IV, respectively. There were 91 (26.6% cases with local residual diseases, 27(7.9% developed distant metastasis, and 18(5.26% pts had local recurrence. Discussion: The results of this study suggest that radical radiotherapy with HDR brachytherapy was appropriate for the treatment of early staged cancer of uterine cervix. For locally advanced cancer of cervix addition of concurrent chemotherapy, higher radiation doses, reduction of overall treatment time to less than 8 weeks, and use of latest radiotherapy techniques such as IMRT is recommended to improve the results.

    子宫是孕育胚胎、胎儿和产生月经的器官.同时,子宫也是容易发生恶性肿瘤的器官.从子宫颈到子宫体,子宫内膜到子宫肌层,各部位均可发生恶性肿瘤.宫颈癌是最常见的妇科恶性肿瘤,高危型人乳头瘤病毒(HPV)的持续性感染是引起宫颈癌前病变和宫颈癌的主要原因.宫颈癌的主要病理类型为鳞状细胞癌和腺癌,确诊依赖于宫颈病灶的活体组织病理检查,对病变程度的判断采用国际妇产科联盟(FIGO)的临床分期.宫颈癌的治疗早期以手术为主,中、晚期以放疗为主,辅以化疗的综合治疗.近年来靶向治疗为局部晚期、复发性、转移性宫颈癌提供了新的治疗途径.HPV疫苗也已开始应用于宫颈癌的预防.%The uterus is an organ which nurtures the embryo,fetus and produces menstruation. At the same time.it is also an organ which is likely to suffer from malignant tumor. Each part of the uterus including cervix,corpus uteri,endometrium,myometrium is prone to malignant tumor. Cervical cancer is the most common gynecological malignancies. Persistent infection of high risk papillomavirus is the main reason of precancerous and cervical cancer. The main pathological type was squamous cell carcinoma and adenocarcinoma. Definite diagnosis can depend on cervix biopsy and histopathology. We can judge the severity from the FICO clinical staging. The treatment of early stage cervical cancer is surgery,while in treatment of the middle and advanced stage cervical cancer,radiaotherapy is the core and chemotherapy is the complement. Nowadays targeted therapy provides a new approach to local advanced,recurrent and metastasis cervical cancer. HPV vaccine has been used to prevent the cervical cancer now.

  7. 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.

    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

The 5 year, cumulative survival probability for the whole population was 88.3%. The patients in which carcinoma in situ was detected at the time of diagnosis, showed a cumulative survival probability of 98.8% while those with invasive carcinoma had a value of 68.3%. This difference was statistically significant. The cumulative survival probability for the patients diagnosed with squamous cell carcinoma was 89% while those with adenocarcinoma had a value of 80%. This difference did not fall within the range of statistical significance, though.

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

    The objective of the present study was to estimate cancer risk associated with the low-level radiation exposure of an average annual effective dose of 6.4 mSv (including internal exposure) in the high background-radiation areas (HBRA) in Yangjiang, China. The mortality survey consisted of two steps, i.e., the follow-up of cohort members and the ascertainment of causes of death. The cohort members in HBRA were divided into three dose-groups on the basis of environmental dose-rates per year. The mortality experiences of those three dose groups were compared with those in the residents of control areas by means of relative risk (RR). During the period 1987-1995, we observed 926,226 person-years by following up 106,517 subjects in the cohort study, and accumulated 5,161 deaths, among which 557 were from cancers. We did not observe an increase in cancer mortality in HBRA (RR=0.96, 96% CI, 0.80 to 1.15). The combined data for the period 1979-95 included 125,079 subjects and accumulated 1,698,316 person-years, observed 10,415 total deaths and 1,003 cancer deaths. The relative risk of all cancers for whole HBRA as compared with the control area was estimated to be 0.99 (95% CI, 0.87 to 1.14). The relative risks of cancers of the stomach, colon, liver, lung, bone, female breast and thyroid within whole HBRA were less than one, while the risks for leukemia, cancers of the nasopharynx, esophagus, rectum, pancreas, skin, cervix uteri, brain and central nervous system, and malignant lymphoma were larger than one. None of them were significantly different from RR=1. Neither homogeneity tests nor trend tests revealed any statistically significant relationship between cancer risk and radiation dose. We did not find any increased cancer risk associated with the high levels of natural radiation in HBRA. On the contrary, the mortality of all cancers in HBRA was generally lower than that in the control area, but not statistically significant. (author)

    Objective To investigate the clinical and pathological characteristics of primary cervical malignant melanoma,and its prognosis.Methods The clinical and pathological data of four patients with primary malignant melanoma of the cervix were analyzed retrospectively. Nerve tissue protein S-100 and monoclonal antibody to melanoma (HMB-45) were measured in all cases by immunohistochemical method. All four patients received radical hysterectomy. Three of them received chemotherapy preoperation or postoperation, and one of them received biotherapy with interferon-γ and interleukin-2 at the same time. All the cases were followed up.Results The average age of four patients was 45 years. Clinical symptoms presented with irregular vaginal bleeding,postcoital bleeding, or increase of vaginal discharge. Gynecologic examination showed polypus papilla cauliflower-shaped or nodulated black-brown or black-blue mass on the cervix. All the four cases were pathologically diagnosed with cervical malignant melanoma. S-100 and HMB-45 were positive in all patients. Two patients died at 6 and 41 months postoperation, respectively. The other two patients survived for 3.5 and 7 years postoperation, respectively.Conclusions S-100 protein and HMB-45 play very important roles in the diagnosis of primary malignant melanoma of cervix. Radical hysterectomy, chemotherapy combined with dimethyl triazemo imidazole carboxamide and biological therapies may improve the prognosis of the primary malignant melanoma of cervix ifthe disease could be diagnosed in an early stage.

    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)

    The initial value of the standardized uptake value is not statistically associated to the tumor response after chemoradiotherapy in the uterine cervix carcinomas. It is observed a trend to a better tumor response in case of S.U.V. ( standardized uptake value) higher on the PET before therapy. A study bearing on a more important number of patients is necessary to measure its predictive value. (N.C.)

    Full Text Available Introduction: Pap smear or Pap test is a cytological method based on sampling from the cervix (or neck of the womb in women and preparation of smear and direct observation under microscope. Pap smear is now used as a common test for screening in women. Since the Pap smear method has been used as a screening test for early detection of cervical cancer, the incidence of aggressive cervical cancer and mortality caused by it has reduced by 70%. So, conducting of experiments to improve the quality of prepared slides and reduction of red blood cells by proper fixators for better diagnosis of the disease are the purposes of this research. This study is aimed to comprise the adequacy of Pap smear taken from the cervix using conventional fixative spray and Carnoy’s fixative methods. Methods: this study was performed on 202 blood Pap smear slides taken from 101 cervixes of women with abnormal uterine bleeding. These patients referred to Zeinabieh and Shahid Faghihi Hospitals related to Shiraz University of Medical Sciences in 2012 and 2013. After observation of two bleedings, two Pap smear slides were prepared from each sample; both of prepared slides from cervical cells of each sample were fixed at first by conventional fixative spray and one of them was then placed in Carnoy’s solution for 22 minutes and air-dried. The slides were then stained with Papanicolaou stain and examined by two different cytologists in a double-blind fashion. The obtained data were analyzed by SPSS. Results: the results showed that the presence of squamous cells (p=0.004, glandular cells (p=0.001, transformation zone cells (p=0.001, cellular inadequacy (p=0.002, distribution of inflammatory cells (p=0.001 and metaplastic cells (p=0.001 were more on the spray-fixed slides. The mean percentage of blood on the slides (p=0.091 and distribution of microbial agents (p=1 on the spray-fixed and Carnoy’s-fixed slides did not show statistically a significant difference.

    Full Text Available This study assesses the morbidity and complications of treatment among long-term survivors of cervical cancer. Ninety-eight female patients who were diagnosed and treated from invasive carcinoma of the cervix uteri 5 years or more are included in this study. All the cases were free of disease and had survived up to December 2010. Forty-one cases were treated with radical hysterectomy with removal of the lymph nodes (Wertheim’s surgery (42%. Radical radiation therapy was given to 57 cases (58% according to our treatment protocol; weekly cisplatin was given concomitantly with radiation. Although urinary adverse effects were more prevalent among the radiation group, the difference was not statistically significant. Bowel dysfunction was more prevalent and statistically significant (p\\0.001 among the radiotherapy arm. Dysfunctions recorded included change in bowel habit, diarrhea, constipation, tenesmus, soiling of clothes and or flatulence. However, their severity was grade 1–2 only. The frequency of small intestinal obstruction was comparable in both arms. Pelvic vein thromboses had a tendency to occur among the surgical group especially in obese females (p value 0.005. The frequency of sexual dysfunction was comparable in both groups with no statistical difference. It was age related. The younger the patients’ ages, the more was the sexual complaint irrespective to the treatment modality. Sexual problems included dyspareunia from vaginal stenosis shortening or dryness, vulval soreness from itching and dryness. Bearing in mind that many patients had more than one health complaint. The remaining cases denied the presence of any complications and stated that they had a normal life style.

    We studied the cell-type-specific and temporal expression of c-fos and c-jun protooncogenes after 17beta-estradiol (E2) stimulation in the uteri of immature 3-week-old mice neonatally exposed to diethylstilbestrol (DES), DES-mice, and the ontogenic expression of these genes in the uteri of DES-mice using immunohistochemistry and in situ hybridization. A single E2 injection induced the transient and rapid expression of c-fos mRNA and c-Fos protein in the endometrial epithelium and endothelial cells of the blood vessels in both 3-week-old vehicle-treated controls and DES-mice; a peak of mRNA expression was 2 hours after E2 injection and that of protein expression was 2 to 3 hours after the injection. The expression of c-fos mRNA and protein after E2 stimulation was lower in the DES-mice than in the control animals. There were no significant differences in the c-jun expression patterns in both experimental groups before and after the E2 injection. The E2 injection transiently down-regulated the c-jun expression in the epithelium and up-regulated it in the stroma and myometrium. The uterine epithelium of DES-mice showed much stronger c-Jun immunostaining on days 4 and 10, compared with those of controls. Neonatal DES treatment reduced c-Jun immunoreactivity in the uterine epithelium on days 4 and 10, and increased the reaction in the stroma on day 4. These results suggested that the neonatal DES treatment induces permanent changes in the c-fos expression pattern independent of the postpuberal secretion of ovarian steroids. The changes in the expression of c-fos and c-jun protooncogenes, particularly during postnatal development, are likely to play important roles in the production of uterine abnormalities in the DES-mice.

    Full Text Available One of the most common cancers among Indian women is the cancer of cervix. Hence, the Present study is undertaken to determine the prevalence of HR-HPV DNA in women in Delhi / NCR regions. The significance of detection of HPV provides the base to be used as a tool to identify women, at the risk of subsequent development of cervical cancer. It is the utmost necessity to identify the prevalence of high risk- Human Papilloma Virus (HR-HPV in the women with cervical cytology for early treatment. Total of 1931 samples (cervical samples from different hospitals in Delhi / NCR regions of India were collected in between January 2006 to December 2009. The cervical cytobrush was used for collection of samples from cervix and then the samples were transported in virus transport media (Digene Diag, Md. Hybrid capture assay II (HCA II for HPV DNA detection from Digene Diagnostics (Silver Spring, Md. was used for the detection of High risk Human Papilloma Virus. High risk Human Papilloma Virus was detected in 232 cases (12.01%. As analyzed it was observed that positivity rate has increased for last few years, 9.49 %, 11.66 %, 11.94 %, 14.7 %, in the year 2006, 2007, 2008, and 2009 respectively.

    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

    Primary malignant melanoma (MM) accounts for 1% of all cancers, and only 3% to 7% of these tumors occur in the female genital tract. Data are limited with respect to the basis for treatment recommendations because of the rarity of MM. The overall prognosis of melanomas of the female genital tract is very poor. Two cases of MM of the female genital tract are presented. The first case is of a 70-year-old female patient who complained of left thigh pain and underwent magnetic resonance imaging that showed cervical cancer with involvement of the vagina, bladder, and parametrium, in addition to multiple bony metastases of the proximal femur, acetabulum, and both iliac bones. The second case is of a 35-year-old female patient who suffered from vaginal bleeding for 5 months, and she was diagnosed as having primary vaginal melanoma. The patient underwent radical surgery and two additional surgeries because of recurrence of cancer in both inguinal areas. After surgery, the patient received adjuvant immunotherapy, radiation therapy, and chemotherapy. In both the aforementioned cases, the pathologic diagnosis was made after immunohistochemical analysis, i.e., the tumor cells were stained with HMB-45 and S100, and were found to be positive for both immunostains.

    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. In conclusion, use of cloprostenol is an acceptable treatment for open-cervix pyometra in queens.

    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.

    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)

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

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

    331 patients of stage IIb uterine cervix cancer treated by radiation alone at Kosin Medical Center between June 1980 and Dec. 1985 were analysed to determine parameters of radiotherapy associated to disease states. Survival rate was highest among the reported (82.8% for crude and 82.4% for disease free survival). Pelvic control rate in 6 weeks after the end of radiotherapy was 93.6% in the patients treated with ICR following total pelvic radiation and 71.6% with small field additional external irradiation. 5 year survival rate in those who achieved pelvic control was 98. 9% and 12.9% in those who had pelvic failure and/or metastasis after radiation. The survival rate figured maximal 88.5% with dosage of 7500-8500 cGy to point A with acceptable incidence of complications (4.9%) but without increasing survival above it and minimal 74.1% with dosage of less than 6500 cGy. The treatment failure was counted 18.7% (62 of 331 patients): Local failure 72. 6% ( 45 of 62 patients), locoregional failure 3.2% (2 of 62 patients) and distant failure 24% (15 of 62 patients). Late complications were found In 50 patients (15.1%) and 42% of them was rectal bleeding and stenosis. The dose of 8500 cGy to point A was found to be critical for complication and 70% of complications occurred above it and was more serious one such as fistula. Rectal complications were developed above rectal dose 6500 cGy and bladder complication above bladder dose 7500 cGy. Major cause of death was cachexia due to locoregional failure (73.7% of death), next was due to metastasis to lung, liver and bone, and only 3 patients died of complication of intestinal perforations and obstruction. In conclusion higher external radiation dose for a bulky uterine cervix and barrel shaped uterus was essential for local control.

    Full Text Available 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.

    2002-10-15

    The difficulty of traversing the cervix severely limits transcervical artificial insemination (TC AI) in sheep. Cervical trauma and poorly designed instruments can reduce fertility after AI. To overcome problems associated with TC AI, we developed a new TC AI catheter. Three bench experiments were conducted to determine the effects of the new TC AI catheter on semen quality independent of the effects of moving the catheter through the cervix. In each of the three bench experiments, the standard laparoscopic instrument for intrauterine AI in sheep was used as the control for the TC AI catheter. In Experiment 1, the total volume of semen extender expelled and void volumes for both types of AI instrument (TC versus laparoscopic) were determined. In Experiment 2, the effects of each type of AI instrument (TC versus laparoscopic) on semen quality, estimated as percentage motility and percentage forward progressive motility, of frozen-thawed semen was determined. In Experiment 3, the effects of both types of AI instrument (TC versus laparoscopic) on number of spermatozoa expelled was determined. The type of AI instrument affected neither semen quality nor the number of spermatozoa expelled. However, void volume differed (P synchronize estrus, progestogenated pessaries were inserted and left in place for 12 days. On Day 5 after pessary insertion, PGF2alpha (15 mg) was given i.m. At pessary removal, 400 IU of eCG were administered i.m. Ewes were inseminated 48-52 h after pessary removal using fresh diluted semen (200 x 10(6) to 350 x 10(6) spermatozoa per 0.2 ml) pooled from the same four rams each day during the experiment. At 72 h after AI, uteri were collected postmortem and flushed. Oocytes and embryos were recovered and evaluated. Treatments did not affect (P > 0.01) ovum and embryo recovery rate (mean = 87.3%), fertilization rate (59.3%), or Day 3 pregnancy rate (mean = 66.6%). We conclude from these data that the use of our new TC AI catheter for TC AI or

    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.

    A small dose of prostaglandin E2 suspended in a viscous medium was instilled as a single application into the extra-amniotic space of patients with unfavourable induction features the day before planned induction in an attempt to improve the condition of the cervix. Two groups of 15 patients were studied, one receiving prostaglandin E2 250 mug suspended in methyl ethyl cellulose ('Tylose') 6% solution, and the other tylose alone. Cervical status did not change in those receiving tylose alone, whereas a significant improvement occurred in 14 out of 15 patients receiving the prostaglandin. Labour began before formal induction in 1 patient receiving tylose and in 8 receiving prostaglandin.

    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 smooth muscle function is established, but comparatively little is known about cervical smooth muscle pharmacology. We performed a proof-of-principle experiment that smooth muscle was expressed in the cervix in both virgin and pregnant rats, using the uterus as a comparator. We tested whether all tissues were pharmacologically responsive to contractile and relaxant agonists. Immunohistochemistry revealed the expression of smooth muscle α-actin in all tissues. The isolated tissue bath was used to measure isometric contractility of uterine strips and whole cervices from virgin and pregnant (day 11 ± 2) female Sprague-Dawley rats. We tested classic activators of uterine smooth muscle contraction and relaxation in both uterus and cervix. All tissues contracted to the depolarizing agent potassium chloride, prostaglandin F2α, muscarinic cholinergic agonist carbachol [2-[(aminocarbonxyl)oxy]-N,N,N-trimethylethanaminium chloride], and 5-hydroxytryptamine. Unlike other tissues, the pregnant cervix did not contract to oxytocin, but the oxytocin receptor was present. Both cervix and uterus (virgin and pregnant) had concentration-dependent, near-complete relaxation to the adrenergic agonist norepinephrine and adenylate cyclase activator forskolin [(3R,4aR,5S,6S,6aS,10S,10aR,10bS)-6,10-10b-trihydroxy-3,4a,7,10a-pentamethyl-1-oxo-3-vinyldodecahydro-1H-benzo[f] chroment-5-yl acetate]. The β-adrenergic receptor agonist isoproterenol was less potent in pregnant cervix versus virgin by ∼10-fold. All tissues, particularly the cervix, responded poorly to the nitric-oxide donor sodium nitroprusside, relaxing ∼20% maximally. These findings support the importance of smooth muscle in the cervix, the use of the isolated cervix in pharmacological studies, and a similarity between smooth muscle pharmacology of the nonpregnant uterus and cervix. This work highlights the unappreciated smooth muscle function of the cervix versus uterus and cervical changes in pharmacology during

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

    2016-01-01

    Full Text Available Background: Pulmonary lymphangitic carcinomatosis (LC secondary to cervical squamous cell carcinoma (SCC is an uncommon cause of diffuse infiltrative lung disease. Its reported incidence is quiet low. Materials and Methods: Fifty cases of cervical carcinoma were studied from 2005 to 2014. There was only one case of squamous cell carcinoma cervix that developed pulmonary lymphangitic carcinomatosis subsequently. Clinical manifestations of LC such as dyspnea and non-productive cough can mimic with clinical picture of pneumonia, pneumonitis, pulmonary embolism, congestive heart failure, asthma, and sarcoidosis and thus can be a diagnostic dilemma for treating physician. A review of world literature was also done to examine all the reported cases of cervical carcinoma which presented as pulmonary lymphangitic carcinomatosis. A few cases have been reported so far. Concussion: Pulmonary lymphangitic carcinomatosis is a rare manifestation of metastatic Squamous Cell Carcinoma (SCC of the cervix and is associated with a poor prognosis. Increased clinical alertness of such patterns of metastases in cervical cancer along with accurate pathological diagnosis is compulsory to guide proper therapy in these patients.

    Previous studies have shown the involvement of the immune response in the progression of human uterine cervix cancer. The aim of this study was to determine the expression of Interleukin-2 (IL-2), IL-2 receptor (IL-2R) and Interleukin 10 (IL-10) in different grades of cervical intraepithelial neoplasias of the exocervix (CIN 1, 2 and 3), and its relationship with the serum cytokine profiles and human papilomavirus (HPV) infection status. Indirect immunofluorescence was used to study the expression of IL-2, IL-2R and IL-10 in human cervical samples from 50 patients and 9 normal controls. Serum IL-2, IL-2R and IL-10 were measured by ELISA and HPV DNA and HPV types were identified by PCR. Increased number of IL-2, IL-2R and IL-10 positive cells were observed in the cervix from patients with CIN, associated with the grades of dysplasia. A significant correlation was observed between IL-2 and IL-2R (p>0.0001), IL-2 and IL-10 (p>0.0001), as well as IL-10 and IL-2R (p>0.0001). Twenty percent of patients were HPV positive and 84% of those patients were tissue cytokine positive. These results suggest that IL-2, IL-2R and IL-10 tissue expression may play a role in the development of cervical intraepithelial dysplasias.

    Although uterus and cervix infiltration is a frequent finding in the later stages of lymphomatous disease, primary lymphoma of the cervix is very uncommon; however, this entity can occasionally be distinguished from cervical carcinoma by means of MRI. This is an important fact as treatment and prognosis differ between these neoplasms. We present a case of primary cervical lymphoma studied with high-field (1.5 T) MRI and we make an extensive review of the literature. The cervical mass was found in a routine pelvic examination in a patient with no previous history of gynecologic disorders. This is an uncommon way of presentation of this disease. T2-weighted turbo spin-echo (TSE) sequences in the axial, sagittal, and coronal planes, and T1-weighted SE pre- and post-contrast images, were obtained. The lack of involvement of the mucosa, as well as sparing of cervical stroma and uterine junctional zone, are the most important findings to differentiate cervical lymphoma from carcinoma, and are best evaluated with T2 TSE sequences. Post-contrast images help to delineate the extent of the disease. (orig.)

    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.

    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)

    Full Text Available Abstract Background There is scant information on whether Human Immunodeficiency Virus (HIV seropositivity has an influence on the outcome of treatment of precancerous cervical lesions using cryotherapy. We studied the prevalence of cervical abnormalities detectable by visual inspection and cervical lesions diagnosed by colposcopy according to HIV serostatus and described the outcomes of cryotherapy treatment. Methods Trained nurses examined women not previously screened for cervical cancer using visual inspection with acetic acid (VIA and Lugol's iodine (VILI in two family planning/post natal clinics in Kampala, Uganda, from February 2007 to August 2008. Women with abnormal visual inspection findings were referred for colposcopic evaluation and HIV testing. Women with precancerous cervical lesions detected at colposcopy were treated mainly by cryotherapy, and were evaluated for treatment outcome after 3 months by a second colposcopy. Results Of the 5 105 women screened, 834 presented a positive screening test and were referred for colposcopy. Of these 625 (75% returned for the colposcopic evaluation and were tested for HIV. For the 608 (97.5% women in the age range 20-60 years, colposcopy revealed 169 women with cervical lesions: 128 had inflammation, 19 had low grade squamous intraepithelial lesion (LGSIL, 13 had high grade squamous intraepithelial lesion (HGSIL, 9 had invasive cervical cancer and 2 had inconclusive findings. Detection rates per 1 000 women screened were higher among the older women (41-60 years compared to women aged 20-40 years. They were accordingly 55% and 20% for inflammation, 10% and 2% for LGSIL, 5% and 2% for HGSIL, 6% and 1% for invasive cervical cancer. Of the 608 women, 103 (16% were HIV positive. HIV positivity was associated with higher likelihood of inflammation (RR = 1.7; 95% CI: 1.2-2.4. Conclusions Detection rates were higher among older women 41-60 years.

    Results of thirty two autopsies in the cases of carcinoma of the cervix experienced in ten years were analyzed. Fourteen cases received surgery and postoperative irradiation. Fourteen cases had external irradiation combined with intracavitary irradiation. Cancer was the cause of death in 81.3% of the whole cases, and it caused cachexia in many cases of the two groups. Uremia and uremic complication were found in 8 cases of the operative group, and in 2 of the radiotherapy group. High incidences of intrapelvic local recurrence and metastasis to other organs were found in the operative group. Cancerous infiltrative involvement of the bladder was often observed, such as in 11 cases of the operated group and in 9 cases of the irradiation group. Cancerous hydronephrosis was found in 10 and 5 cases of the operation and irradiation group, respectively; non-cancerous hydronephrosis was found in 2 of the former and in 4 of the latter. The radiotherapy group had a longer survival period than the other, without severe side effects in the urinary system. This suggested that radiotherapy is of value in treatment of cervical cancer.

    Full Text Available BACKGROUND: Invasive squamous cell carcinoma of cervix remains the most common malignant neoplasm of the female genital tract in many countries. The Papanicolaou stained cervical smear is an excellent and effective method in the diagnosis of invasive carcinoma and precancerous lesions of the cervix. This study was conducted to assess the value of Feulgen stained cervical smears in elucidating nuclear features help ful in the diagnosis of malignancy over conventional Pap stained smears and also to look for micronucleated cells in suspected cases of carcinoma of cervix. AIM: To analyse the distribution of cases of invasive squamous cell carcinoma and intraepithelial n eoplasia (squamous intraepithelial lesion of cervix over a period of 3 years, to elucidate additional nuclear features helpful in diagnosis of carcinoma using Feulgen stained cervical smears and to study the distribution of micronuclei in Feulgen stained smears from suspected cases of Carcinoma cervix. MATERIALS AND METHODS: A three year analysis of all cases of dysplasia and invasive carcinoma of cervix was done by reviewing Papanicolaou stained cervical smears from all the diagnosed cases of invasive car cinoma and precancerous lesions of the cervix. Cervical smears from sixty clinically suspected cases of carcinoma of cervix and smears from 10 normal women collected during a period of 12 months were studied in detail using Papanicolaou stained and Feulgen Stained Smears and micronuclei analysis (MN analysis was done. RESULTS : A total of 24343 cervical smears were screened during the 3 year period of study. Out of these 24343 cases there were 267(1.09% cases of cervical intraepithelial neoplasia and 144(0 .592% cases of invasive squamous cell carcinoma. Micronuclei analysis done using Feulgen Stained Smears demonstrated a consistent increase in micronucleated cells proportional to the increase in severity of th e lesion from normal to invasive carcinoma.

    Full Text Available Background and Purpose: Conventional portals, based on bony anatomy, for external beam radiotherapy for cervical cancer have been repeatedly demonstrated as inadequate. Conversely, with image-based conformal radiotherapy, better target coverage may be offset by the greater toxicities and poorer compliance associated with treating larger volumes. This study was meant to dosimetrically compare conformal and conventional radiotherapy. Materials and Methods: Five patients of carcinoma cervix underwent planning CT scan with IV contrast and targets, and organs at risk (OAR were contoured. Two sets of plans-conventional and conformal were generated for each patient. Field sizes were recorded, and dose volume histograms of both sets of plans were generated and compared on the basis of target coverage and OAR sparing. Results: Target coverage was significantly improved with conformal plans though field sizes required were significantly larger. On the other hand, dose homogeneity was not significantly improved. Doses to the OARs (rectum, urinary bladder, and small bowel were not significantly different across the 2 arms. Conclusion: Three-dimensional conformal radiotherapy gives significantly better target coverage, which may translate into better local control and survival. On the other hand, it also requires significantly larger field sizes though doses to the OARs are not significantly increased.

    Early detection through screening plays a major role in reducing the impact of cervical cancer on patients. When detected before the invasive stage, precancerous lesions can be eliminated with very limited surgery. Polarimetric imaging is a potential alternative to the standard screening methods currently used. In a previous proof-of-concept study, significant contrasts have been found in polarimetric images acquired for healthy and precancerous regions of excised cervical tissue. To quantify the ability of the technique to differentiate between healthy and precancerous tissue, polarimetric images of seventeen cervical conization specimens (cone-shaped or cylindrical wedges from the uterine cervix) are compared with results from histopathological diagnoses, which is considered to be the "gold standard." The sensitivity and specificity of the technique are calculated for images acquired at wavelengths of 450, 550, and 600 nm, aiming to differentiate between high-grade cervical intraepithelial neoplasia (CIN 2-3) and healthy squamous epithelium. To do so, a sliding threshold for the scalar retardance parameter was used for the sample zones, as labeled after histological diagnosis. An optimized value of ˜83% is achieved for both sensitivity and specificity for images acquired at 450 nm and for a threshold scalar retardance value of 10.6 deg. This study paves the way for an application of polarimetry in the clinic.

    Full Text Available Melanosis of the uterine cervix is an extremely rare melanocytic lesion and should be differentiated from melanoma. It is a melanocytic hyperpigmentation of basal layer cells from the squamous mucosa of the uterine cervix without an increase in the number of melanocytes. We present a typical case of this entity. Furthermore, we discuss the possible origins of melanocytes in this region and their association with Laugier-Hunziker syndrome and Carney complex.

    The implementation of new drug treatments has improved the prognosis for advanced cancers of the cervix, uterus, and ovary. Platinum analogs are the most effective drugs in the treatment of ovarian cancer. Other drugs, such as oxaliplatin, have been proposed as a rational treatment of platinum refractory ovarian cancer. Epothilones are also being studied in clinical trials, as are histone deacetylase inhibitors. Several promising agents may soon receive Food and Drug Administration approval.

    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.

To study the risk of ADC in HIV1+patients with good immune status (CD4≥500/mm3 for at least 2 years. Methods Incident ADC (Kaposi's sarcoma [KS], non-Hodgkin's lymphomas [NHL] and cervix uteri cancer [CUC] were retrieved in HIV1+adults followed in the French hospital database on HIV (FHDH cohort between 1992 and 2009. Cancer incidence rates (IR in general population were calculated using data from the French cancer registries (Francim network. IR among the HIV1+and the general population were standardized using the 5 years age and sex groups structure of the HIV1+population (1997–2009 and standardized incidence ratios (SIR were estimated in HIV1+ patients vs. general population in 4 calendar periods (1992–1996, 1997–2000, 2001–2004, and 2005–2009. Median age at diagnosis was estimated after adjusting for the difference in age structure between HIV1+and general population. Summary of results 5,935 incident ADC were diagnosed among 100,536 HIV1+ patients followed between 1992 and 2009. All ADC IRs were significantly reduced between pre- and post-cART eras and continue to decline in the cART period (p<10−4.

    Full Text Available Objetivo: Estimar la probabilidad acumulada de sobrevida a cinco años, de una cohorte de pacientes diagnosticadas con cáncer de cervix durante 1999. Metodología: Para el análisis de la información se utilizaron distribuciones de frecuencia con valores absolutos y porcentuales, medidas de tendencia central y de dispersión. La relación entre variables cualitativas se efectuó mediante la prueba estadística de Chi cuadrado (X2. El nivel de significancia se fijó en p < 0.05. La probabilidad acumulada de sobrevida fue realizada mediante el método de Kaplan-Meier. La comparación entre los tiempos de sobrevida se realizó mediante el test de rangos logaritrnicoso El nivel de significancia fue fijado en p < 0,05. Resultados: Se analizaron 778 casos al final del periodo de estudio fallecieron 91 pacientes. La probabilidad acumulada de sobrevida a los cinco años para toda la población fue del 88,3%. Las pacientes a las cuales se les detectó carcinoma in situ al momento del diagnóstico, presentaron una probabilidad acumulada de sobrevida de 98,8%, mientras que a aquellas a quienes se les detectó un carcinoma invasor, fue del 68,3%. Esta diferencia fue estadísticamente significativa. La probabilidad acumulada de sobrevida para las pacientes diagnosticadas con carcinoma de células escamosas fue de un 89%, mientras que para aquellas diagnosticadas con adenocarcinoma fue de un 80%. Esta diferencia no fue estadísticamente significativa. Conclusiones: Los resultados obtenidos muestran valores superiores a los determinados en otros países con un nivel de desarrollo inferior al nuestro, y similares a los encontrados en naciones desarrolladas. Con los resultados obtenidos, se podría suponer que las probabilidades acumuladas de sobrevida son mayores en aquellas pacientes a quienes se les realiza el diagnóstico de cáncer de cervix en edades tempranas, y que esto puede relacionarse con la alta proporción de carcinomas in situ diagnosticados en

    Purpose: Our study aims at evaluating the cost of pulsed dose-rate (P.D.R.) brachytherapy with optimized dose distribution versus traditional treatments (iridium wires, cesium, non-optimized P.D.R.). Issues surrounding reimbursement were also explored. Materials and methods: This prospective, multi-centre, non-randomized study conducted in the framework of a project entitled 'Support Program for Costly Diagnostic and Therapeutic Innovations' involved 21 hospitals. Patients with cervix carcinoma received either classical brachytherapy or the innovation. The direct medical costs of staff and equipment, as well as the costs of radioactive sources, consumables and building renovation were evaluated from a hospital point of view using a micro costing approach. Subsequent costs per brachytherapy were compared between the four strategies. Results: The economic study included 463 patients over two years. The main resources categories associated with P.D.R. brachytherapy (whether optimized or not) were radioactive sources (1053 Euros) and source projectors (735 Euros). Optimized P.D.R. induced higher cost of imagery and dosimetry (respectively 130 Euros and 367 Euros) than non-optimized P.D.R. (47 Euros and 75 Euros). Extra costs of innovation over the less costly strategy (iridium wires) reached more than 2100 Euros per treatment, but could be reduced by half in the hypothesis of 40 patients treated per year (instead of 24 in the study). Conclusion: Aside from staff, imaging and dosimetry, the current hospital reimbursements largely underestimated the cost of innovation related to equipment and sources. (authors)

    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 Registered-Sign 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.

    1987-06-01

    To investigate whether age is a prognostic factor in patients with carcinoma of the cervix, a retrospective study was undertaken of 261 patients, aged 45 years or less, who were referred to the Rotterdamsch Radio-Therapeutisch Instituut (RRTI) between 1973 and 1982. Patients were referred for either primary treatment--surgery or radiotherapy--or for adjuvant radiotherapy. Overall 5-year survival figures were rather low, which may be explained by negative patient selection as the RRTI is a referral hospital: stage IB, 72%; stage IIA; 61%; stage IIB; 52%; stage III; 29%. A particular poor survival was noted for patients (n = 22) aged 28 or less. Overall 5-year survival of these patients was only 39% in contrast to 67% 5-year survival of older patients. This difference was highly significant (p less than 0.002). Even if corrected for stage, very young patients had a poorer prognosis (stage IB: 45% versus 75% 5-year survival of older patients). Within the older age group, no trend towards a better prognosis with increasing age could be identified. As a treatment was similar for all patients, no explanation is available for this observation.

    For examination by electron microscopy tissue samples were taken from the posterior lip of the cervix of 8 patients having a termination of pregnancy at 9-12th week gestation and 16 patients of comparable gestational age who had an intracervical application of either 2 ml 5% tylose or 50 micrograms sulprostone-tylose gel 8 hours before biopsy. The efficacy of cervical priming was demonstrated objectively by tonometric studies. In addition, collagenase and protease activities were determined in the cervical tissue extracts of the different treatment groups. For identification of typical collagen fragments SDS-polyacrylamide-gel-electrophoresis were carried out on the acetic acid soluble extracts. The local application of sulprostone gel induced a marked multifocal loosening of the collagenous framework; there was no evidence for leucocyte infiltration or necrosis caused by the prostaglandin (PG) pretreatment. In the areas of disorganized collagen fibres cervical fibroblasts seemed to be activated characterized by fine granular loosening of the cytoplasma, dilated cisternae of rough endoplasmatic reticulum, vacuolized enlarged mitochondria and an increased number of cytoplasmatic vesicles close to the cell surface. Collagenase and protease activities were found in all extracts of the different treatment groups, however, PG-application led to no significant increase in enzymatic activities. There was no evidence for the presence of typical collagen cleavage products in the SDS-electrophoresis. Contradictory to the hitherto published literature enzymatic collagen degradation does not play an essential role in PG-induced cervical ripening.

    Full Text Available Background: Standard treatment of advanced cervical cancer is concurrent chemoradiation. Radical radiotherapy for carcinoma cervix includes pelvic external beam radiotherapy (EBRT with the concomitant platinum based chemotherapy followed by intracavitary brachytherapy (ICBT to boost central disease. Management of patients who are suboptimally treated, especially, after unsuccessful ICBT insertion is not well-defined. This study explores the role of hysterectomy in these patients. Materials and Methods: From January 2006 to December 2011, 38 patients with locally advanced cervical cancer, in whom ICBT insertion was unsuccessful, were analyzed retrospectively. Operable patients with no parametrial involvement underwent hysterectomy and outcomes (recurrence free and overall survival were noted. Results: The major complications in post operative period were wound infection, paralytic ileus and bladder atony all of which were conservatively managed with no mortality. At median follow-up of 36 months (range 12-60 months there was no recurrence in patients with stage 1B2 and stage IIA, 25 out of 38 (65.8% were event free and the overall survival was 71%. Conclusion: Many patients in Indian scenario receive suboptimal therapy in locally advanced cervical cancer. EBRT with chemotherapy followed by type 1 extra-fascial hysterectomy can be a good alternative for these patients.

    Cervical cancer is the third most common cancer in women worldwide. The hypermethylation of P16, TSLC-1 and TSP-1 genes was analyzed in squamous cell carcinomas (SCC), cervical intraepithelial lesions (CIN) and adenocarcinomas (ADC) of the uterine cervix (total 181 lesions). Additionally human papillomavirus (HPV) type, EPB41L3, RASSF1 and RASSF2 hypermethylation were tested in ADC and the results were compared with those obtained previously by our group in SCC. P16, TSLC-1 and TSP-1 hypermethylation was more frequent in SCCs than in CINs. These percentages and the corresponding ones for EPB41L3, RASSF1 and RASSF2 genes were also higher in SCCs than in ADCs, except for P16. The presence of HPV in ADCs was lower than reported previously in SCC and CIN. Patients with RASSF1A hypermethylation showed significantly longer disease-free survival (P = 0.015) and overall survival periods (P = 0.009) in ADC patients. To our knowledge, this is the first description of the EPB41L3 and RASSF2 hypermethylation in ADCs. These results suggest that the involvement of DNA hypermethylation in cervical cancer varies depending on the histological type, which might contribute to explaining the different prognosis of patients with these types of tumors.

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.

    -effectiveness ratio (ICER) of topotecan plus cisplatin versus cisplatin monotherapy was 17,974 pounds per QALY in the main licensed population, 10,928 pounds per QALY in the cisplatin-naive population (including stage IVB patients) and 32,463 pounds per QALY in sustained cisplatin-free interval patients. In response to the point for clarification raised by the ERG, the manufacturer submitted a revised indirect comparison incorporating HRQoL and a longer time horizon. Where the hazard ratio derived from GOG-0169 was employed, paclitaxel plus cisplatin was dominated by topotecan plus cisplatin, but, where the hazard ratio from GOG-0204 was adopted, paclitaxel plus cisplatin was found to have an ICER of 13,260 pounds per QALY versus topotecan plus cisplatin. At present there is a paucity of evidence available on the clinical effects of topotecan plus cisplatin and the effects of palliative treatment in general for women with advanced and recurrent carcinoma of the cervix. Further trials, or the implementation of registries, are required to establish the efficacy and safety of topotecan plus cisplatin. The guidance issued by NICE on 28 October 2009 as a result of the STA states that topotecan in combination with cisplatin is recommended as a treatment option for women with recurrent or stage IVB cervical cancer, only if they have not previously received cisplatin. Women who have previously received cisplatin and are currently being treated with topotecan in combination with cisplatin for the treatment of cervical cancer should have the option to continue therapy until they and their clinicians consider it appropriate to stop.

    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.)

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

    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...

    The available information on the incidence of cancers by site in India have indicated that of incidence of cancer of uterine cervix among women is by far the highest compared to other sites in women. The epidemiology of cervical cancer has been studied extensively in India and in other countries. The majority of factors related to cervical cancer are associated with sexual behaviour. The available evidence for control of cervical cancer is through secondary prevention, namely--early detection...

    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.

  3. Pseudoneoplastic glandular lesions of the uterine cervix: a selective review.

    Nucci, Marisa R

    2014-07-01

    Pseudoneoplastic glandular lesions of the cervix continue to be diagnostically challenging for the surgical pathologist. This review covers a select number of these lesions that may be misinterpreted as premalignant or malignant, with an emphasis on those about which Dr Scully has advanced our knowledge. The topics covered include microglandular hyperplasia, mesonephric hyperplasia, diffuse laminar endocervical glandular hyperplasia, lobular endocervical glandular hyperplasia, and endocervical adenomyoma. The first listed entity has a greater diversity of morphology than the name might imply including, but not limited to solid growth and prominent hyaline stroma. The second entity may be remarkably diffuse within the cervical wall and reasonably result in consideration of diagnoses such as minimal deviation adenocarcinoma (adenoma malignum), but has nonmucinous epithelium and bland cytology. The third entity, one of the least common of those considered, represents a peculiar form of reactive hyperplasia of the endocervical epithelium. The fourth entity is the one about which knowledge is still fast advancing. In pure form with no atypia it is almost certainly a clinically benign process, but a subset of cases show cytologic atypia and an occasional association with adenocarcinoma is seen. Finally, adenomyomas of the uterus in general have received much attention in recent years, mostly in the corpus, but the less common endocervical variant may be particularly problematic because mucinous epithelium in abundant myogenic stroma may be potentially confused with an infiltrating differentiated mucinous adenocarcinoma. Although immunohistochemistry may play a role on occasion in evaluating benign endocervical glandular proliferations the mainstay of their interpretation remains conventional morphologic analysis of routinely stained slides.

    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.

    2012-01-01

    Full Text Available Malignant melanoma (MM and blue nevi of the uterine cervix are an extremely rare neoplasm, probably derived from embryologic migration of melanocytes from the neural crest. MM displays aggressive behavior with a poor prognosis. We report the case of a 76-year-old postmenopausal woman abnormal vaginal bleeding. She underwent a hysterectomy and bilateral salpingo-oophorectomy with paraaortic-iliac lymphadenectomy. Histopathological and immunohistochemical studies were consistent with the diagnosis of MM and blue nevi in the uterine cervix. Although it is extremely rare, this case suggests that MM of the uterine cervix should be considered in the differential diagnosis of undifferentiated neoplasm. Early diagnosis is essential in order to warrant a better prognosis, although there are no cases of cure described.

    Extramedullary (extraosseous) plasmacytomas are localized, plasma cell neoplasms that arise in tissues other than bone and bone marrow, and constitute about 4% of all plasma cell neoplasms. Extramedullary (extraosseous) plasmacytomas rarely affects the female lower genital tract; only 6 cases of primary cervix plasmacytomas have been reported to date. Here we describe the case of an otherwise healthy 21-year-old woman who presented for a routine examination with no symptoms. A Pap smear showed an intense inflammatory process with some atypical cells. This was confirmed by microscopic examination of a biopsy, which revealed a metaplastic process of the cervix with a massive infiltration of plasma cells with mild atypia. The atypical plasma cells showed cytoplasmic lambda immunoglobulin light chain restriction with the absence of kappa light chains, indicative of monoclonality. The patient was extensively screened for systemic disease, including bone marrow biopsy, but the disease was restricted to the cervix.

    OBJECTIVE A sonographically short cervix is a powerful predictor of spontaneous preterm delivery. However, the etiology and optimal management of a patient with a short cervix in the mid-trimester of pregnancy remain uncertain. Microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation are frequently present in patients with spontaneous preterm labor or acute cervical insufficiency. This study was conducted to determine the rate of MIAC and intra-amniotic inflammation in patients with a cervical length <25 mm in the mid-trimester. STUDY DESIGN A retrospective cohort study was conducted of patients referred to our high risk clinic because of a sonographic short cervix or a history of a previous preterm birth. Amniocenteses were performed for the evaluation of MIAC and for karyotype analysis in patients with a short cervix. Fluid was cultured for aerobic and anaerobic bacteria, as well as genital mycoplasmas. Patients with MIAC were treated with antibiotics selected by their physician. RESULTS Of 152 patients with a short cervix at 14–24 weeks, 57 had amniotic fluid analysis. The prevalence of MIAC was 9% (5/57). Among these patients, the rate of preterm delivery (<32 weeks) was 40% (2/5). Microorganisms isolated from amniotic fluid included Ureaplasma urealyticum (n=4) and Fusobacterium nucleatum (n=1). Patients with a positive culture for Ureaplasma urealyticum received intravenous Azithromycin. Three patients with Ureaplasma urealyticum had a sterile amniotic fluid culture after treatment, and subsequently delivered at term. The patient with Fusobacterium nucleatum developed clinical chorioamnionitis and was induced. CONCLUSION 1) Sub-clinical MIAC was detected in 9% of patients with a sonographically short cervix (<25 mm); and 2) maternal parenteral treatment with antibiotics can eradicate MIAC caused by Ureaplasma urealyticum. This was associated with delivery at term in the three patients whose successful treatment was documented by

    The cervical collagen remodeling during the estrous cycle of the ewe was examined. The collagen concentration determined by a hydroxyproline assay and the area occupied by collagen fibers (%C), determined by van Gieson staining, were assessed in the cranial and caudal cervix of Corriedale ewes on Days 1 (n = 6), 6 (n = 5), or 13 (n = 6) after estrous detection (defined as Day 0). In addition, the gelatinase activity by in situ and SDS-PAGE gelatin zymographies and matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9, respectively) expression by immunohistochemistry were determined. The collagen concentration and %C were lowest on Day 1 of the estrous cycle (P MMP-2 activity was highest (P MMP-2 trend to be highest (P = 0.0819). The MMP-2 activity was detected in 73% of the homogenized cervical samples, and its expression was mainly detected in active fibroblasts. By contrast, the MMP-9 activity was detected in 9% of the samples, and its scarce expression was associated with plasmocytes, macrophages, and lymphocytes. Matrix metalloproteinase-2 expression was maximal on Day 1 in the cranial cervix and on Day 13 in the caudal cervix and was lower in the cranial than in the caudal cervix (P MMP-2 expression that differed between the cranial and caudal cervix may reflect their different physiological roles. The decrease in the collagen content and increase in fibroblast MMP-2 activity in sheep cervix on Day 1 of the estrous cycle suggests that cervical dilation at estrus is due to the occurrence of collagen fiber degradation modulated by changes in periovulatory hormone levels.

    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.

    The purpose of this study was to evaluate treatment results in terms of the survival and failure patterns subsequent to radiation therapy in recurrent cervical cancer, following primary surgery. Between January 1990 and December 1999, 27 patients, with recurrent cervical cancer following primary surgery, were subsequently treated with radiation in the Department of Radiation Oncology, at the Keimyung University Dongsan Medical Center. Their median age was 48, ranging from 31 to 70 years old. With regard to the initial FIGO stage on presentation, 20 and 7 patients were stages I and II, respectively. Twenty three patients had squamous ceH carcinomas and 4 had adenocarcinomas. The time interval from the primary surgery to the recurrence ranged from 2 to 90 months with a median of 29 months. The recurrent sites were the vaginal cuff alone, the pelvic cavity and combined recurrence in 14, 9 and 4 patients, respectively. Radiation was performed, with external and vaginal intracavitary radiation in 13 patients, external radiation alone in 13 and vaginal intracavitary radiation alone in another one. The median follow-up period was 55 months, ranging from 6 to 128 months. The five year disease free survival (5y DFS) and five year overall survival (5y OS) rates were 68.2 and 71.9%, respectively. There was a marginal statistically significant difference in the 5y DFS in relation to the recurrent site (5y DFS, 85.7% in vaginal cuff recurrence alone, 53.3% in pelvic cavity recurrence, p=0.09). There was no difference in the survival according to the time interval between the primary surgery and a recurrence. There was only a 7% local failure rate in the patients with a vaginal cuff recurrence. The major failure patterns were local failure in the patients with pelvic cavity recurrence, and distant failure in the patients with a combined recurrence. There were no complications above grade 3 after the radiation therapy. Radiation therapy was safe and effective treatment for a

    Full Text Available Abstract Background The glycosylation of a great number of molecules, glyco-protein or glycolipids, has been of interest for decades. Objective To compare the expressive patterns of the isoantigenic determinants of histo-blood groups ABH and Lewis in squamous and simple epithelium and in precursors and cancers of the cervix. Methods A total of 36 lesions and neoplasms (10 LG-SIL, 16 HG-SIL and 10 invasive carcinomas have been studied with immunohistochemical techniques, using monoclonal antibodies (MoAb BG1 to BG8 for precursor chains, blood-group ABH and Lewis group Lea, Leb, Lex, and Ley, and four types of lectins. In addition, we have studied the expression of p53 protein and PCNA, establishing the rate of proliferation of each lesion. Using PCR techniques, we have also detected part of the intron of the E6 gene of HPV-16. Results In the invasive cervical carcinomas, we observed a loss of expression of the Lex antigen (p y antigens. With PCNA, we established a proliferative rate which tended to be greater in relation to the progression of the cervix neoplasms. Conclusion These results indicate that there is a relation between the losses of histo-blood groups and the progression of the squamous intraepithelial lesions.

    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

    Schaffer, P

    1995-05-01

    The first Cancer Registries were created in 1975 in France. Their ulterior development and their scientific production have been furthered by the apparition from 1986 under the aegis of the Health Ministry and of the INSERM, of a National Population Registry Committee. Cancer Registries have seriously contributed to a better knowledge of the cancer problem in our country and to describe the french specificities, in particular the importance of the mouth and pharynx cancers. They insure both a monitoring and an alert role; they also contribute to the medical supervision of the Chernobyl accident effects. French registries play a very active role concerning clinical research. They participate to many European studies of health care evaluation. In other respects, many etiological studies have been realized about professional risks of cancer, risks linked with nutritional habits, and on the etiologic role of the Tamoxifen. Finally, certain registries have created DNA banks. If nowadays their role in health planning remains modest, they very actively contribute in evaluating screening actions of breast, cervix and large bowel cancers. They also attracted the attention of Health Authorities on the cervix cancer screening's incoherencies. They evaluate the pilot project of the breast cancer and the registry of the Côte d'Or country evaluates the efficacity of a randomized colo rectal mass screening study. The main difficulties met by the registries are linked with the development of laws protecting more and more the individual freedoms, making it harder and harder the registration exhaustive character.

    A rare variant of malignant melanoma (MM) of the uterine cervix that mimics a malignant peripheral nerve sheath tumor (MPNST) is described. A 43-year-old white woman was admitted to the hospital complaining of genital discharge and vaginal bleeding. Neoadjuvant chemotherapy and total abdominal hysterectomy and bilateral salpingo-ovariectomy plus pelvic lymphadenectomy were performed, and the diagnosis was MPNST, FIGO IIB. Pathological examination showed a diffuse proliferation of amelanotic spindle cells and large, highly atypical, frequently multinucleated, bizarre, and S100-, HMB-45-, vimentin-positive cells. The patient remained disease-free for 43 months, when an abdominal computed tomographic scan showed local polypoid vaginal lesions, with histological features of typical MM. A pathological review was obtained in our institution by a gynecological pathologist, who defined the primary neoplasm in the cervix as an MM, with a pattern of growth histologically simulating an MPNST, metastatic to the vagina. To our knowledge, this is the first report in literature of MM of the uterine cervix resembling MPNST. Despite its rarity, this variant of MM should be considered when a diagnosis of cervix MPNST is made. The histological and immunohistochemical features of these different entities should be considered in the differential diagnosis.

    Full Text Available Non-Hodgkin’s lymphoma of the cervix is an extremely uncommon entity, with no standard established treatment protocol. A 43-year-old asymptomatic female with a history of dual hit blastic B-cell lymphoma/leukemia in complete remission presented with an incidental cervical mass, which was initially felt to represent a cervical fibroid on computed tomography (CT. It was further evaluated with ultrasound, biopsy, and positron emission tomography-computed tomography (PET-CT, which demonstrated a growing biopsy-proven lymphomatous mass and new humeral head lesion. The patient was started on chemotherapy to control the newly diagnosed humeral head lesion, which then regressed. She then underwent radiation to the cervix with significant improvement in the cervical lymphoma. A review of cross-sectional imaging findings of lymphoma of the cervix is provided, including how to differentiate it from other more common diseases of the cervix. Clinical awareness of rare cervical masses such as lymphoma is very important in order to achieve timely diagnosis and appropriate treatment.

    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.

    1984-01-01

    Alterations in tannic acid (TA) binding capacity of cell surface carbohydrates in normal, premalignant, and malignant squamous epithelium of the human uterine cervix have been studied using electron microscopic visualization in combination with microdensitometric evaluation. While in normal epithelium there is distinct binding in four to five cell layers of the deep intermediate zone, cells of carcinoma in situ and invasive cancer lesions lack TA binding. In moderate dysplasia an intermediate reacting pattern is found. Deep intermediate cells in areas bordering the carcinoma in situ lesions do not show any binding, although their ultrastructure cannot be distinguished from similar cells in normal tissue. The TA deposition within the deep intermediate zone is probably related to the presence here of glycoprotein-containing membrane-coating granules. The finding that TA binding discriminates between cells in normal squamous epithelium and morphologically normal cells in juxtaposition with lesional areas in premalignant and malignant epithelium opens the possibility for a more reliable cytologic diagnosis of cervical epithelial neoplasia.

    In diagnostic cytology, it has been advocated that molecular techniques will improve cytopathological diagnosis and may predict clinical course. Ancillary molecular techniques, however, can be applied only if a sufficient number of preparations are made from a single cell sample. We have developed the AgarCyto cell block procedure for multiple molecular diagnostic analyses on a single scraping from the uterine cervix. The optimized protocol includes primary fixation and transport in ethanol/carbowax, secondary fixation in Unifix, and embedding in 2% agarose and then in paraffin according to a standard protocol for biopsies. More than 20 microscopic specimens were produced from a single AgarCyto cell block, and standard laboratory protocols have been successfully applied for H&E staining, immunohistochemistry for Ki-67 and p53, and in situ hybridization for the centromere of human chromosome 1 and human papilloma virus Type 16. In addition, single AgarCyto sections yielded sufficient input DNA for specific HPV detection and typing by LiPA-PCR, and the protocol includes an option for DNA image cytometry. The AgarCyto cell block protocol is an excellent tool for inventory studies of diagnostic and potentially prognostic molecular markers of cervical cancer.

    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.

    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.

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

    Since its recognition about 150 years ago, there has been much progress in the understanding of the pathogenesis, prevention, early detection and management of carcinoma of the uterine cervix. Important historical landmarks include the (1) recognition of pre-invasive and pre-clinical lesions, and the devise of various systems for reporting these lesions, (2) improvements in diagnostic techniques particularly colposcopy, (3) advent of therapeutic procedures (electrocoagulation, cryotherapy, laser therapy and loop electrosurgical excision), and (4) recognition of the aetiological relationship between the human papillomavirus and cervical neoplasia. The susceptibility of the cervical transformation zone to malignant change is now well recognised. The WHO classification system remains the one most commonly utilised for histological reporting of cervical cancers. In the recent 1994 update, cervical carcinoma is divided into 3 main categories: squamous cell carcinoma, adenocarcinoma and other epithelial tumours. Squamous cell carcinoma (60-80%) predominates among invasive cervical carcinoma. Recognised variants include verrucous, warty (condylomatous), papillary squamous (transitional) and lymphoepithelioma-like carcinoma. Adenocarcinoma (5-15% of invasive carcinomas) shows an increasing trend in young females. Like its squamous counterpart, preinvasive and microinvasive versions are known. Variants such as mucinous, endometrioid, clear cell, mesonephric, serous, villoglandular and minimal deviation carcinoma are now defined. Adenosquamous carcinoma (5-25%), adenoid-cystic, adenoid-basal, neuroendocrine and undifferentiated carcinomas constitute other epithelial tumours of the cervix. The management of invasive cervical carcinoma remains heavily dependent on its stage. The FIGO staging system remains the most widely used. The 1995 update provides more definite criteria in subdividing stage IA tumours by delimiting stromal invasion of stage IA1 lesions to a maximum depth

    Glassy cell carcinoma (GCC) is a histologically aggressive subtype of cervical cancer with rapid growth and early metastases. The prognosis for patients with GCC is poor. This article reviews the literature pertinent to the epidemiology, cytology, pathology, immunohistochemistry, treatment and prognosis of GCC. MEDLINE (PubMed) was searched for all articles or abstracts on patients diagnosed with GCC published (in English) since the original definition by Glucksmann and Cherry, Cancer 1956;9:971. Accurate diagnosis of GCC enables implementation of the correct treatment strategy. Early-stage GCC should be treated with hysterectomy and pelvic lymph node dissection, with adjuvant radiochemotherapy if at least one intermediate or high risk factor for cervical cancer is present. Advanced GCC should be treated with neoadjuvant radiochemotherapy or chemotherapy with the aim of making the disease operable. There is a need for retrospective evaluation of GCC treatment from several centres to explore knowledge about this rare entity. Future studies should explore the role of targeted therapies and the most efficient chemotherapy regimen for the management of GCC.

    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.

    Full Text Available The purpose of this retrospective study is to report the radiotherapy treatment response of, and complications in, patients with cervical cancer on the basis of cumulative biologic effective dose (BED and overall treatment time (OTT. Sixty-four (stage II - 35/64; stage III - 29/64 patients of cervical cancer were treated with combination of external beam radiotherapy (EBRT and low dose rate intracavitary brachytherapy (ICBT. The cumulative BED was calculated at Point A (BED 10 ; and bladder, rectal reference points (BED 2.5 using the linear-quadratic BED equations. The local control (LC rate and 5-year disease-free survival (DFS rate in patients of stage II were comparable for BED 10 < 84.5 and BED 10 > 84.5 but were much higher for BED 10 > 84.5 than BED 10 < 84.5 ( P < 0.01 in stage III patients. In the stage II patients, The LC rate and 5-year DFS rate were comparable for OTT < 50 days and for OTT> 50 days but were much higher in stage III patients with OTT < 50 than OTT> 50 days ( P < 0.001. It was also observed that patients who received BED 2.5 < 105 had lesser rectal ( P < 0.001 and bladder complications than BED 2.5 > 105. Higher rectal complication-free survival (CFS R rate, bladder complication-free survival (CFS B rate and all-type late complication-free survival rate were observed in patients who received BED 2.5 < 105 than BED 2.5 > 105. A balanced, optimal and justified radiotherapy treatment schedule to deliver higher BED 10 (>84.5 and lower BED 2.5 (< 105 in lesser OTT (< 50 days is essential in carcinoma cervix to expect a better treatment outcome in all respects.

    A retrospective study was conducted to evaluate the effect of Arabin cervical pessary in twin pregnancies with cervical length (CL)  <25 mm between 21 and 31 weeks. Forty patients receiving pessary were matched with 40 controls without pessary. They were matched for gestational age (GA) at admission and CL. GA at delivery, delivery before 36, 34 and 32 weeks, latency between detection of short cervix and delivery, and duration of hospital admission were compared between groups. Women with the pessary delivered at higher GA compared to controls (35 vs. 33 weeks, p = 0.02). Cervical pessary significantly reduced the incidence of delivery  <36 and  < 34 weeks (p < 0.05), but not before 32 weeks. Interval between detection of short cervix and delivery was longer in the pessary group and duration of hospital admission was shorter (p = 0.03) compared to women without pessary.

    Mullerian adenosarcoma is a rare biphasic malignant neoplasm of the cervix characterized by an admixture of benign epithelial elements and a malignant sarcomatous stromal component, which may be either homologous or heterologous. An aggressive variant of adenosarcoma, mullerian adenosarcoma with sarcomatous overgrowth (MASO) is extremely rare, with only two such cases being reported in the English literature to date. In this report we present a case of MASO of uterine cervix with heterologous elements in a 15-year-old unmarried girl presenting with foul smelling menstrual bleeding and passage of fleshy masses. Because MASO with heterologous elements seems to appear at the earliest stages of reproductive lifespan in women, and have an uncertain malignant potential, gynecologists and pathologists should be aware and think about the possibility of this tumor.

    Full Text Available A case of secondary infertility related to prolonged retention of fetal bones in the cervix is presented. A 34-year-old nulliparous woman was admitted to the hospital with chronic pelvic pain, dyspareunia, and 12%u2013year-long secondary infertility following an induced abortion due to fetal demise. Transvaginal ultrasonography (USG revealed a linear echogenic area around the posterior cervical wall. An hysteroscopic examination confirmed the existence of an irregular calcified mass embedded in the cervix. The mass turned out to be conglomerated fetal bone fragments which probably acted as an intrauterine device. After removal of the cervical mass, the patient conceived spontaneously within four months. The present case report emphasizes the significance of a detailed history and a thorough evaluation by transvaginal USG in the case of secondary infertility following an induced or spontaneous abortion.

    1992-01-01

    The influence of spasmoanalgetic Dolantin on electrical activity of the smooth musculature of the cervix during labour was studied in 50 primiparous women after induction of labour. The highest electrical activity was measured at the time of uterine contraction (AC) and between contractions (BC). The basic pattern of Dolantin-produced changes in muscular contractions in the cervix observed via EMG activity is that of the EMG activity diminishing with contractions of the uterine corpus and even more so in the period between contractions. Dolantin administered during the latent phase of induced labour did not accelerate cervical dilatation either in the latent or in the active phase of amniotomy- and Oxytocin-induced labour.

    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.

    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

    Full Text Available "nBackground: Uterine contractions and an appropriate cervix are two important factors in labor contributing to good pregnancy outcomes. Oxytocin and prostaglandins, such as misoprostol, are used for the induction of labor. Misoprostol is used for cervical ripening and labor induction. The aim of this trial was to compare the efficacy and safety of titrated oral misoprostol solution with oxytocin for labor induction in pregnant women with an unfavorable cervix."n "nMethods: In this randomized double-blind clinical trial, 140 women with a gestational age of 34-42 weeks and an unfavorable cervix were recruited. The participants had an indication for labor induction and had been referred to the Women's Hospital in Tehran, Iran between January 2010 and January 2011. The participants were randomly assigned to receive 20 µg/hour titrated oral misoprostol plus intravenous placebo or 6 mU/min oxytocin plus oral placebo. In case contractions were inadequate, the drug doses were gradually increased. Pharmacological complications, the mean interval from the start of induction till vaginal delivery and delivery type were monitored and analyzed in both groups."n "nResults: The mean interval from the start of induction till vaginal delivery in misoprostol group was shorter than the oxytocin group (11.07±3.42 vs. 14.87±3.21 hours, P=0.001. The frequency of pharmacological complications and vaginal or cesarean deliveries were similar between the two groups (P>0.05."n "nConclusion: Use of titrated oral misoprostol is a safe and effective method for labor induction in pregnant women with unfavorable cervix. Misoprostol is associated with a shorter interval from induction to vaginal delivery than oxytocin.

    Full Text Available We investigated the in vitro effect of the essential oil of Croton nepetifolius Baill., Euphorbiaceae (EOCN, on spontaneous or induced contractions of circular and longitudinal muscles from the ovine cervix during the luteal phase of the estrous cycle. The relaxant effect of EOCN was expressed as a percentage of the contraction recorded before the addition of the oil and calculated relative to the preparations exposed only to the vehicle. The IC50 (concentration of oil required to produce a 50% maximal reduction in muscle contraction for relaxation of spontaneous contractions in circular and longitudinal muscles was significantly lower than the IC50 for blockade of K+-induced contraction (27.19 µg mL-1 versus 262.72 µg mL-1 and 40.92 µg mL-1 versus 222.47 µg mL-1, respectively. Interestingly, there was a high degree of selectivity in the action of EOCN on cervix layers concerning the inhibition of acetylcholine-induced contraction in circular (IC50 277.10 µg mL-1 and longitudinal (IC50 52.56 µg mL-1 muscles. In conclusion, EOCN is able to relax ovine cervix during the luteal phase. This work opens the perspective of applying EOCN in ovine embryo transfer.

    Withdrawal of progestational support for pregnancy is part of the final common pathways for parturition, but the role of nuclear progesterone receptor (PGR) isoforms in this process is not known. To determine if the PGR-B isoform participates in cervical remodeling at term, cervices were obtained from mice lacking PGR-B (PGR-BKO) and from wild-type (WT) controls before or after birth. PGR-BKO mice gave birth to viable pups at the same time as WT controls during the early morning of Day 19 postbreeding. Morphological analyses indicated that by the day before birth, cervices from PGR-BKO and WT mice had increased in size, with fewer cell nuclei/area as well as diminished collagen content and structure, as evidenced by optical density of picrosirius red-stained sections, compared to cervices from nonpregnant mice. Moreover, increased numbers of resident macrophages, but not neutrophils, were found in the prepartum cervix of PGR-BKO compared to nonpregnant mice, parallel to findings in WT mice. These results suggest that PGR-B does not contribute to the growth or degradation of the extracellular matrix or proinflammatory processes associated with recruitment of macrophages in the cervix leading up to birth. Rather, other receptors may contribute to the progesterone-dependent mechanism that promotes remodeling of the cervix during pregnancy and in the proinflammatory process associated with ripening before parturition.

    Quercetin could have profound effects on uterine morphology and proliferation, which are known to be influenced by estrogen. This study investigated the effect of quercetin on these uterine parameters in the presence and in the absence of estrogen. Ovariectomized adult female rats received peanut oil, quercetin (10, 50, and 100 mg/kg/day), estrogen, or estrogen+quercetin (10, 50, or 100 mg/kg/day) treatment for 7 consecutive days. At the end of the treatment, uteri were harvested for histological and molecular biological analyses. Distribution of proliferative cell nuclear antigen (PCNA) protein in the uterus was observed by immunohistochemistry. Levels of expression of PCNA protein and mRNA in uterine tissue homogenates were determined by Western blotting and real-time polymerase chain reaction, respectively. Our findings indicated that administration of 10 mg/kg/day of quercetin either alone or with estrogen resulted in decreased uterine expression of PCNA protein and mRNA with the percentage of PCNA-positive cells in uterine luminal and glandular epithelia markedly reduced compared with estrogen-only treatment. Changes in uterine morphology were the opposite of changes observed following estrogen treatment. Treatment with 100 mg/kg/day of quercetin either alone or with estrogen resulted in elevated PCNA protein and mRNA expression. In addition, the percentages of PCNA-positive cells in the epithelia, which line the lumen and glands, were increased with morphological features mimicking changes that occur following estrogen treatment. Following 50 mg/kg/day quercetin treatment, the changes observed were in between those changes that occur following 10 and 100 mg/kg/day quercetin treatment. In conclusion, changes in uterine morphology and proliferation following 10 mg/kg/day quercetin treatment could be attributed to quercetin's antiestrogenic properties, while changes that occur following 100 mg/kg/day quercetin treatment could be attributed to

    Currently available prophylactic vaccines have no therapeutic efficacy for preexisting human papillomavirus (HPVs) infections, do not target all oncogenic HPVs and are insufficient to eliminate the burden of HPV induced cancer. We aim to develop an alternative HPV vaccine which is broadly effective...... and capable of clearing preexisting infection. In an initial attempt to develop a broadly reactive therapeutic vaccine, we designed a putative papillomavirus (PV) ancestor antigen (circulating sequence derived antigenic sequences E1E2-CDSE1E2) based on the conserved E1 and E2 protein sequences from existing...... vaccines induced long-lasting potent CDSE1E2 specific T cell responses in outbred mice. This prime-boost regimen was then tested in female macaques naturally infected with MfPVs. All immunized animals (16/16) responded to the vaccine antigen but with reduced cross-reactivity against existing PVs...

    Endometrial and cervical cancers are the most prevalent gynecologic neoplasms. While endometrial cancer occurs in older women, cervical cancer is more prevalente in young subjects. The most common clinical manifestation in these two gynecological cancers is vaginal bleeding. In the first case, diagnosis is made based on histological and imaging evaluation of the endometrium, while cervical cancers are diagnosed clinically, according to the International Federation of Gynecology and Obstetrics (FIGO). The authors present a case of synchronous gynecological cancer of the endometrium and cervix diagnosed during staging on MRI and confirmed by histological analysis of the surgical specimen.

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

    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.

    Primitive neuroectodermal tumors of the cervix are very rare. A 28-year-old pregnant woman presented with a cervical mass. The tumor was staged as IB2. The biopsy from tumor was suggestive of malignant small round cell tumor. She then underwent termination of pregnancy followed by radical hysterectomy. Based on morphologic and immunohistochemical profile, a diagnosis of peripheral primitive neuroectodermal tumor of the cervix was made. The patient received adjuvant chemotherapy and radiotherapy. The patient is alive and disease-free 33 months post-surgery. The present case highlights the importance of keeping primitive neuroectodermal tumors in the differential diagnosis of small cell neoplasms of the uterine cervix. Pregnancy should not be a barrier to early detection and treatment of this potentially aggressive tumor. The optimal treatment methods have not yet been established because of the rarity of the tumor.

    The primary cause of death in women in the world is cancer. In most developing countries cancer of the cervix is the most prevalent cancer. Breast cancer has this distinction in Latin America and the developed countries of North America, Europe, Australia, and New Zealand. It is also the most prevalent cancer worldwide. The most common cancer in Japan and the Soviet Union is stomach cancer. Effective early detection programs can reduce both breast and cervical cancer mortality and also the degree and duration of treatment required. In Iceland, cervical cancer mortality declined 60% between the periods of 1959-1970 and 1975-1978. Programs consist of mammography, physician breast and self examination, and Pap smear. The sophisticated early detection equipment and techniques are expensive and largely located in urban areas, however, and not accessible to urban poor women and rural women, especially in developing countries. Tobacco smoking attributes to 80-90% of all lung cancer deaths worldwide and 30% of all cancer deaths. Passive smoking increases the risk of lung cancer to 25-35% in nonsmokers who breathe in tobacco smoke. Since smoking rates of women are skyrocketing, health specialists fear that lung cancer will replace cervical and breast cancers as the most common cancer in women worldwide in 20-30 years. Tobacco use also contributes to the high incidence of oral cancer in Southern and South Eastern Asia. For example, in India, incidence of oral cancer in women is 3-7 times higher than in developed countries with the smoking and chewing of tobacco in betel quid contributing. Techniques already exist to prevent 1/3 of all cancers. If cases can be discovered early enough and adequate treatment applied, another 1/3 of the cases can be cured. In those cases where the cancer cannot be cured, drugs can relieve 80-90% of the pain.

    The authors discuss 10 cases--seven after vaginal and cervical rupture, 2 after Caesarean section and 1 after hysterectomy. Six of them died--5 after rupture of the vagina and cervix and one after Caesarean section. The lethal issue was avoidable in all cases because it was a result of untimely done or not done at all hysterectomy and other interventions, e.g., ligation of the hypogastric arteries, as well as of faulty surgical performance. Basic principles of surgical behavior in such cases are postulated.

    Full Text Available Abstract Sarcomas constitute less than 1% of all cervical malignancies. With over 150 reported cases, rhabdomyosarcomas represent the most commonly reported sarcoma at this location. In this report, a select group of the more uncommon sarcomas of the uterine cervix are reviewed, including all previously reported examples of leiomyosarcoma, liposarcoma, alveolar soft part sarcoma, Ewing sarcoma/primitive neuroectodermal tumor, undifferentiated endocervical sarcoma, and malignant peripheral nerve sheath tumor (MPNST. Emphasis is placed on any distinctive clinicopathologic features of these entities at this unusual location.

    Full Text Available BACKGROUND: Preterm labor, failure to progress, and postpartum hemorrhage are the common causes of maternal and neonatal mortality or morbidity. All result from defects in the complex mechanisms controlling labor, which coordinate changes in the uterine fundus, lower segment, and cervix. We aimed to assess labor-associated gene expression profiles in these functionally distinct areas of the human uterus by using microarrays. METHODS AND FINDINGS: Samples of uterine fundus, lower segment, and cervix were obtained from patients at term (mean +/- SD = 39.1 +/- 0.5 wk prior to the onset of labor (n = 6, or in active phase of labor with spontaneous onset (n = 7. Expression of 12,626 genes was evaluated using microarrays (Human Genome U95A; Affymetrix and compared between labor and non-labor samples. Genes with the largest labor-associated change and the lowest variability in expression are likely to be fundamental for parturition, so gene expression was ranked accordingly. From 500 genes with the highest rank we identified genes with similar expression profiles using two independent clustering techniques. Sets of genes with a probability of chance grouping by both techniques less than 0.01 represented 71.2%, 81.8%, and 79.8% of the 500 genes in the fundus, lower segment, and cervix, respectively. We identified 14, 14, and 12 those sets of genes in the fundus, lower segment, and cervix, respectively. This enabled networks of co-regulated and co-expressed genes to be discovered. Many genes within the same cluster shared similar functions or had functions pertinent to the process of labor. CONCLUSIONS: Our results provide support for many of the established processes of parturition and also describe novel-to-labor genes not previously associated with this process. The elucidation of these mechanisms likely to be fundamental for controlling labor is an important prerequisite to the development of effective treatments for major obstetric problems

    Tubercolosis is a frequent bacterial infection in less developed countries. Lung and lymph node localisations are common, while the genital apparatus is less involved. In this work a rare case of cervical tuberculosis followed by some lesions causing infertility in a 20-year-old woman is reported. The diagnosis was confirmed by a histological examination from a biopsy of the cervix. The patient was offered six-month antituberculosis therapy which eliminated the cervical lesions. A few years later she came under our care for infertility due to uterine adhesions diagnosed by hysterosalpingography. Now the patient is being treated for infertility complicated by amenorrhoea.

    @@ Alveolar soft part sarcoma (ASPS) is a rare tumor that was originally named by Christopherson in 1952.1Until now, fewer than 200 cases have been described in the literature. The ASPS on the uterine cervix is a very rare malignant tumor of the female reproductive organs.Including the first case described by Flint et al2 in 1985,there have been only a few cases reported to date, of which two were in China, and there is a lack of insightful analysis of treatment options. Therefore, to raise awareness of this disease, we performed a detailed literature review, which includes a case encountered by ourselves.

    Full Text Available Most uterine cervix adenocarcinomas are primary tumors. Here, we report a case of pancreatic cancer that metastasized to the uterine cervix. The patient was a 77-year-old Jehovah's Witness whose pancreatic cancer had been diagnosed 10 years previously. As she had refused blood transfusion on religious grounds, the tumor only underwent segmental excision, followed by radiofrequency wave therapy and chemotherapy. During a routine health examination 6 years after her pancreatic tumor resection, a tumor in the left lower lobe of her lung was found, and then removed. Three years after the lung surgery, her serum CA19-9 increased. A detailed examination found tumors in the ascending colon and uterine cervix. She underwent chemotherapy and radiotherapy after a right hemicolectomy, endocervical biopsy, and endocervical cytology. At present, about 10 years after her initial diagnosis, she is alive with no recurrence or metastatic findings. Morphologically, well-differentiated pancreatic adenocarcinoma is similar to endocervical type adenocarcinoma and adenocarcinoma in situ of the uterine cervix. Therefore, careful immunohistochemical examination and clear understanding of the patient's clinical information are needed in diagnosing adenocarcinoma in the uterine cervix.

    Objective: 16,922 patients with cancers from 15 sites of Qidong population-based cancer registry in the period of 1982-1991 were analyzed for evaluation of cancer survival as well as different cancer control measures.Methods: Observed survival rate (OS) was computed by the Kaplan-Meier method using EGRET statistical software package. Relative survival (RS) which is the ratio of the OS to the expected rate was calculated by using Qidong life table with respect to sex, age and calendar period of observation. Results: The five-year OS for the 5 leading sites of cancers, liver, stomach, lung,oesophagus, and rectum were 1.8%, 11.6%, 3.0% 3.3%,and 19.9%, respectively. The five-year RS for the 5 sites were 1.9%, 14.0%, 3.6%, 4.2%, and 23.7%, respectively,in which, 1.7%, 14.8%, 3.4%, 4.2%, and 26.0% for males, and 2.7%, 12.7%, 4.1%, 4.0%, and 22.0% for females, respectively. Female patients with breast cancer and cervix cancer had 5-year RS of 54.6% and 33.0%.Conclusion: Cancer survival rates for all sites are poor,in which that of the liver is the lowest, while that of the breast, the highest. The survivals of cancers for all sites,especially for breast, cervix, and leukemia are seen to be lower than those of European countries except for oesophagus, pancreas and lung cancer which do not achieve improved survival both in developing and developed countries. There will be a long way to improve the total cancer survival, as well as the cancer treatment in the developing countries.

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

    To evaluate radiation dose and accuracy with TLD and diode detector when treat total skin with electron beam. Using Stanford Technique, we treated patient with Mycosis Fungoides. 6 MeV electron beam of LINAC was used and the SSD was 300 cm. Also, acrylic speller(0.8 cm) was used. The patient position was 6 types and the gantry angle was 64, 90 and 116 degree. The patient's skin dose and the output were detected 5 to 6 times with TLD and diode. The deviations of dose detected with TLD from tumor dose were CA + 6%, thigh + 8%, umbilicus + 4%, calf - 8%, vertex - 74.4%, deep axillae - 10.2%, anus and testis - 87%, sole - 86% and nails shielded with 4 mm lead + 4%. The deviations of dose detected with diode were - 4.5% {approx} + 5% at the patient center and - 1.1% {approx} + 1% at the speller. The deviation of total skin dose was + 8% {approx} - 8% and that deviation was within the acceptable range({+-}10%). The boost dose was irradiated for the low dose areas(vertex, anus, sole). The electron beam output detected at the sootier was stable. It is thought that the deviation of dose at patient center detected with diode was induced by detection point and patient position.

    This work aimed at determining the local prevalence of adverse effects on women with CaCu that recieved LDR brachytherapy treatment at CECAN. The data was extracted from the patient's and medical physics' departement records. Non Gaussian statistics was used due to dose distribution characteristics. A total of 103 patients were studied with average age of 55±13 years and Ia-IV FIGO clinical clasification. The observed prevalence is higher than that reported by other studies. It was observed that patients with proctitis were prescribed a slightly higher dose than those without adverse effects (90% confidence). Patients with proctitis also presented higher age (95% confidence) when compared with the mean of the studied population. The inverse applies to the group with other adverse effects, its average age is lower than the mean (90% confidence).

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

    Uterine papillary serous carcinoma (UPSC) is a clinically aggressive and morphologically distinctive variant of endometrial carcinoma that has been recognized recently as a distinct entity. The association between radiation therapy (RT) and UPSC is rarely described in the literature. We describe the clinicopathologic features of a 71-year-old patient with UPSC that developed 15 years after radiation therapy for squamous cell carcinoma of cervix, stage IIB. In the subtotal hysterectomy specimen the endometrium was irregular with multifocally raised masses. Microscopically, the tumor was composed of high-grade papillary serous carcinoma focally admixed with solid transitional cell carcinomatous areas and multifocal intraepithelial carcinoma in adjacent atrophic endometrium. The tumor exhibited diffuse infiltrative growth with frequent lymphatic tumor emboli in the myometrium. Immunohistochemical staining for p53 and c-erbB-2 were positive in about 70% of the tumor cells. Carcinoembryonic antigen (CEA) was focally positive. Ki-67 positive cells were present in about 60% of the tumor cells. The tumor directly extended to the cervix and perirectal soft tissue and metastasized to the omentum. Intraoperative pelvic washing cytology was positive for papillary adenocarinoma cells. The possible etiologic role of radiation is discussed, and the literature on endometrial carcinomas developing after RT is reviewed.

    Idiopathic preterm labour is the greatest single perinatal problem occurring in an unpredictable 6-8% of all pregnancies and accounting for 75% of all perinatal deaths. Preterm cervical softening is used clinically as an important indicator of cervical dysfunction but the subjective nature of present clinical assessment methods prevents reliable prediction of preterm labour. This paper reports the finding of a pilot investigation concerned with obtaining quantitative measurements of the in vitro electrical impedance of the cervix using a four-electrode multifrequency impedance measurement system. Impedance measurement obtained from six samples of cervical tissue taken from different subjects of caesarean section were fitted to the Cole equation and parameters derived to describe the ratio of extra- versus intracellular impedance and the characteristic frequency. Subjects at term display a lower extra- versus intracellular impedance ratio than the preterm subjects. This appears consistent with the expected increase in the hydration of the cervix approaching term and the resulting decrease in the extracellular impedance. Further studies are required to determine if multifrequency electrical impedance tomography could be used as a non-invasive screening test for preterm labour.

    Ripening of the unfavourable cervix prior to induction of labour using traction on a Foley catheter (32 patients) was compared with 40 mg of prostaglandin F2 alpha in Tylose gel applied to the external cervical os and held in place for 12 hours with a vaginal diaphragm (25 patients). Each patient in the above groups had a modified Bishop score of 0-3 and was randomly allocated to one or other group. Comparison was made with a further 25 patients in whom the cervical score was 4-6. Timing of amniotomy and commencement of Syntocinon infusion were equivalent for all patients. Prostaglandins conferred no advantage over Foley catheter in terms of amniotomy-delivery interval, operative delivery rate, and condition of the baby one minute after birth. The disadvantages of prostaglandins for cervical ripening are a longer preparation-delivery interval, and cost ($77 versus $4.75 for the Foley catheter). Currently, prostaglandins are not officially approved for use in Australia for induction of labour. It is suggested, therefore, that the Foley catheter is preferable for ripening the unfavourable cervix as a prelude to amniotomy.

    OBJECTIVE The aim of the present study was to determine the expression of vascular endothelial growth factor (VEGF) and its receptor, kinase insert domain containing receptor (KDR), and their significance in regulating tumor angiogenesis in the early stages of cervical cancer.METHODS Using the immunohistochemical SP method, the expression of VEGF and KDR was determined in the cancer cells. In addition, the microvessel density (MVD), labeled by CD34 in the tumor stroma, was examined in 18 cases of cervical intraepithelial neoplasms (ClN), 75 cases of early invasive cervix carcinomas (ICC) and 15 specimens of normal cervical epithelium (NCE).RESULTS In ICC cases, VEGF and KDR were mainly expressed in the cellular membrane and/or cytoplasm of tumor cells, while expression of CD34 was found mainly in the vascular epithelial cells of the tumor stroma. The positive expression rate of VEGF and KDR, and the MVD increased remarkably from NCE through CIN to ICC (P<0.01). For the ICC group, in the patients with positive expression of VEGF and KDR, the MVD was significantly higher than those with negative expression of VEGF and KDR (P<0.05). Expression of VEGF in ICC was positively related to KDR expression (r=0.56, P<0.01 ). The MVD was also positively related to both the expression of VEGF (r=0.60, P<0.01), and KDR (r=0.33, P<0.01). In the cases with both positive expression of VEGF and KDR, the MVD was significantly higher than those in which there was negative expression of both (P<0.01 ).CONCLUSION Expression of VEGF and its receptor KDR plays a key role in up-regulating tumor angiogenesis in cervical carcinoma. Co-overexpression of VEGF and KDR results in rapid tumor vasculogenesis. Detection of co-expression of VEGF and KDR may be of value in further understanding tumor angiogenesis and in searching for new targets for anti-angiogenesis therapy in invasive carcinoma of the cervix.

    Preterm birth is a strong contributor to perinatal mortality, and preterm infants that survive are at risk for long-term morbidities. During most of pregnancy, appropriate mechanical function of the cervix is required to maintain the developing fetus in utero. Premature cervical softening and subsequent cervical shortening are hypothesized to cause preterm birth. Presently, there is a lack of understanding of the structural and material factors that influence the mechanical function of the cervix during pregnancy. In this study we build finite element models of the pregnant uterus, cervix, and fetal membrane based on magnetic resonance imagining data in order to examine the mechanical function of the cervix under the physiologic loading conditions of pregnancy. We calculate the mechanical loading state of the cervix for two pregnant patients: 22 weeks gestational age with a normal cervical length and 28 weeks with a short cervix. We investigate the influence of (1) anatomical geometry, (2) cervical material properties, and (3) fetal membrane material properties, including its adhesion properties, on the mechanical loading state of the cervix under physiologically relevant intrauterine pressures. Our study demonstrates that membrane-uterus interaction, cervical material modeling, and membrane mechanical properties are factors that must be deliberately and carefully handled in order to construct a high quality mechanical simulation of pregnancy.

    In blood, the accumulation of terminally differentiated (TD) T cells during HIV infection is associated with CD4 T cell loss and HIV disease progression. Here, we investigated the maintenance and functional characteristics of memory T cells at the cervix. We found that CD4 T cell depletion at the cervix mirrors CD4 depletion in blood. In all women, depletion of CD4 T cells at the cervix was associated with significant reductions in CD45RA- CCR7+ (central memory [CM]) T cells and the accumulation of CD45RA+ CCR7- (TD T cells). We determined whether inflammation in the genital tract was associated with the local differentiation of T cells at the cervix. In uninfected women, genital tract inflammation was associated with the accumulation of CD45RA- CCR7+ CM CD4 T cells and reduced frequencies of CD45RA+ CCR7- TD cells at the cervix. This finding may reflect the fact that, in the absence of HIV infection, TD T cells may be slowly lost in the presence of genital inflammation, while CD45RA- CCR7+ CM T cells are recruited to replenish the diminishing CD4 T cell pool. Following global stimulation with phorbol myristate acetate (PMA)-ionomycin, we noted a significant interleukin 2 (IL-2) deficit in both cervical and blood CD4 T cells from HIV-infected women compared to uninfected women, while gamma interferon (IFN-γ) production was similar, irrespective of HIV status. Few HIV-infected women had detectable IFN-γ and IL-2 HIV-specific T cell responses at the cervix, and these responses were significantly lower in magnitude than the corresponding responses in blood. These data suggest that CD4 depletion was associated with the accumulation of terminally differentiated T cell phenotypes at the cervical mucosa defective in their ability to produce IL-2. CD4 depletion and compromised immunity at the cervix may be accompanied by progressive decline of central memory-like T cells and development of T cells toward terminally differentiated phenotypes.

    The role of enzymatic collagen degradation in prostaglandin-induced and physiological cervical ripening was studied in guinea pigs. The cervices were removed from (a) 8 non-pregnant guinea pigs, (b) 8 animals at day 45 of pregnancy, (c) 14 pregnant animals of comparable gestational age which had either an intracervical application of 0.2 ml 5% tylose or 10 micrograms sulprostone gel, and (d) 8 guinea pigs at day 63 to 65 of pregnancy. Collagenase activity was assayed in a highly specific and sensitive system using native collagen type I as substrate. Protease activity was measured by the method of Green and Shaw. Collagen fragments were identified by SDS-polyacrylamide electrophoresis (SDS-PAGE) of acetic-soluble fractions. Collagenase and protease activities were found in all extracts from the different groups. However, there were no differences in enzymatic activities between the non-pregnant, early-pregnant and late-pregnant cervical specimens. Prostaglandin pre-treatment of the cervix led to no significant increase in either collagenase or protease activity as compared to the control groups. The absence of typical collagen degradation products in the SDS-PAGE suggested that no significant collagen breakdown had taken place. In contrast to previously published literature, we conclude that enzymatic collagen degradation is unlikely to be a key factor in prostaglandin-induced and physiological cervical ripening.

    The potential association between the GSTM1 deletion polymorphism and risk of cervical cancer was investigated in Northeastern Thailand. DNA was extracted from buffy coat specimens of 198 patients with squamous cell carcinoma of the cervix and 198 age-matched healthy controls. Genotyping of the GSTM1 was conducted by using two PCR methods, a short- and a long-PCR. Distribution of the GSTM1 genotypes in between the cases and the controls was not significantly different (p>0.5 by χ2 test). The results suggest that the GSTM1 deletion polymorphism is not a risk factor for squamous cell carcinoma of the cervix in the northeast Thai women.

    Membrane type 1-matrix metalloproteinase (MT1-MMP) participates in the activity of MMP-2, which correlates with cancer of uterine cervix. Single-nucleotide polymorphisms (SNPs) in promoter and exon of MT1-MMP may influence their binding with transcription factors and gene transcription. To date, no study reports the association of the MT1-MMP polymorphisms with cervical neoplasia. Therefore, we investigated the influence of the MT1-MMP gene polymorphisms on the susceptibility and clinicopathological variables of cervical neoplasia for women in Taiwan. We recruited 72 patients with cervical squamous cell carcinoma and 63 with high-grade dysplasia as 1 subgroup. Meanwhile, 280 control women were included as another subgroup. The SNPs rs1003349 (site -165), rs2236307 (+7096), and rs3751489 (+8153) as well as rs2236302 (site +6727) of MT1-MMP gene were determined by polymerase chain reaction (PCR)-restriction fragment length polymorphism and real-time PCR genotyping, respectively. Then, we correlated these SNPs and haplotypes with the development of cervical neoplasia and cancer clinicopathological variables. We found that women with CC genotype in rs2236307 SNP exhibited a more risk to develop cervical neoplasia as compared with those with wild genotype TT. Haplotypes -165 T, +6727 C, +7096 C, +8153 G or -165 G, +6727 G, +7096 T, and +8153 G and diplotypes including at least 1 type of these haplotypes of MT1-MMP gene showed a higher risk of cervical neoplasia. However, both haplotypes were not significantly correlated with the clinicopathological characteristics of cervical cancer. In conclusion, Taiwan women with variant homozygote CC (+7096) and haplotypes, TCCG and GGTG, of MT1-MMP exhibit more risk in developing cervical neoplasia.

    Cancer is predicted to be an increasingly important cause of morbidity and mortality in Bangladesh in the next few decades. The estimated incidence of 12.7 million new cancer cases will rise to 21.4 million by 2030. More than two-thirds of the total expenditure on health is through out-of-pocket payments. According to the Bangladesh Bureau of Statistics, cancer is the sixth leading cause of death. International Agency for Research on Cancer has estimated cancer-related death rates in Bangladesh to be 7.5% in 2005 and 13% in 2030. The two leading causes are in males are lung and oral cancer and in females are breast cancer and cervical cancer. Bangladesh is now in severe shortage of radiation therapy machines, hospital bed, trained oncologists, medical radiation physicists and technologists. Bangladesh having different cancers associated with smoking and smokeless tobacco use, Human papilloma virus infection, Hepatitis B and C infection, Helicobacter Pylori infection, arsenic contaminated groundwater, availability of chemical carcinogens mainly formalin treated fruits, fish and vegetables at open market, tannery waste contaminated with chromium (which is used for poultry feed and fish feed preparation). A World Health Organization study revealed the annual cost of illnesses in Bangladesh attributable to tobacco usage is US$ 500 million and the total annual benefit from the tobacco sector is US$ 305 million as tax revenue. Bangladesh has developed a National Cancer Control Strategy and Action Plan with the aim of delivering a universal, quality-based and timely service. Cancer prevention through tobacco control, health promotion and vaccination program, cancer early detection program for oral cavity, breast and cervix has initiated. Cancer detection and diagnostic facilities will be made available at medical colleges and district- hospitals and establish a referral chain. National capacity development, more cancer research will allow Bangladesh to deal effectively

    Full Text Available Cisplatin and paclitaxel both can cause peripheral neurotoxicity as an adverse effect; however, central nervous system neurotoxicity in the form of seizures is rare. We report a case of a 36-year-old female patient of metastatic carcinoma cervix, who developed seizure shortly after cisplatin infusion. Her laboratory investigations were within normal limits. Computed tomography scan and magnetic resonance imaging of the brain did not reveal brain primary metastasis or meningeal carcinomatosis. She had no complaints of fever, no signs and symptoms of infection, and no history of seizure nor was she on any medication predisposing to such an event. Excluding several causes, seizure was thought to be most likely related to the chemotherapy and cisplatin was the more likely agent in view of observed temporal relationship with the adverse event.

    Full Text Available : INTRODUCTION: Subtrochanteric fractures account for approximately 10-30% of all hip fractures, and they affect persons of all ages. Most frequently, these fractures are seen in 2 patient populations, namely older osteopenic patients after a low-energy fall and younger patients involved in high-energy trauma. A newer population of patients experience subtrochanteric fractures after bisphosphonate use. CASE PRESENTATION: A 45year old Indian woman presented at our orthopaedic outpatients department with 4 months history of pain in left hip and a 1 month history of inability to walk. She had pelvic irradiation for carcinoma of cervix 1 year earlier. Pelvic radiograph confirmed sub trochanteric fracture of left femur. CONCLUSION: Patients with hip pain who have been treated with pelvic irradiation should be thoroughly investigated for hip fractures.

    From August 1978 through December 1980, 119 patients of previously untreated carcinoma of the uterine cervix were treated using RALS, remote afterloading high dose rate intracavitary therapy at our department. The data from 92 out of 119 patients were available for analysis of rectal complication. The incidence of major rectal complications was only 2% (2/92). Uni- and multivariate analyses were used based on the external criterion variable of rectal complication which included even minor injuries. By using these methods, it was clearly indicated that these factors such as TDF of rectum, Z-coordinate of weighted geometric center (WGC-Z), the dose of whole pelvic irradiation, history of chemotherapy and Treponema pallidum hemoagglutination test (TPHA) were important for occurrence of rectal complication. According to discriminant score, 71 out of 92 cases (77%) could be correctly discriminated.

    2010-02-01

    This paper presents a procedure for automatic extraction and segmentation of a class-specific object (or region) by learning class-specific boundaries. We describe and evaluate the method with a specific focus on the detection of lesion regions in uterine cervix images. The watershed segmentation map of the input image is modeled using a Markov random field (MRF) in which watershed regions correspond to binary random variables indicating whether the region is part of the lesion tissue or not. The local pairwise factors on the arcs of the watershed map indicate whether the arc is part of the object boundary. The factors are based on supervised learning of a visual word distribution. The final lesion region segmentation is obtained using a loopy belief propagation applied to the watershed arc-level MRF. Experimental results on real data show state-of-the-art segmentation results on this very challenging task that, if necessary, can be interactively enhanced.

    A digitized fluorescence endoscopic imaging (DFEI) system combined with 5-Aminolevulinic Acid (5-ALA) induced protoporphyrin IX (PPIX) was developed for the detection of neoplasms in the oral cavity and uterine-cervix. The system has the capability of producing both the digital and video fluorescence images in real time, and also quantifying the fluorescence images. The results show that using the DFEI system associated with the fluorescence image quantification method, both high sensitivity and specificity can be achieved during the head and neck, and obstetric and gynaecology clinical trials. The red fluorescence intensity distribution in the lesion area can also be obtained after digital image processing to better understand the situation of PPIX accumulation in the tissues. Furthermore, applying the intensity ratio IR/IB at red and blue wavelength regions of the tissue targeted, where IR includes the intensity of PPIX fluorescence and red tissue autofluorescence, and IB is the intensity of diffusely back-scattered excitation blue light, different histopathological grades of lesions can be classified by the DEFI system, suggesting a significant potential of the noninvasive optical biopsy for the early cancer detection.

    Misoprostol, which is a prostaglandin E1 analogue, is effectively used in cervical priming in women both for labor induction and for gynecological procedures. Although its efficacy is well documented in reproductive age women, during postmenopausal period this efficacy is limited probably due to estrogen deficit. Our objective is to evaluate if estrogen deficit in postmenopausal women is important for the effect of misoprostol on cervical ripening before diagnostic procedures. In this study, 45 patients were randomly allocated to estrogen or placebo group. The study group received local estrogen cream and other group received chlindamycine phosphate cream as placebo. The patients were given oral misoprostol 24 and 12 hours before the procedure for uterine cavity evaluation. Cervix was dilated by using Heagar dilator up to 6 mm. Data were analyzed by Student t-test, Mann-Whitney's U-test, chi-square test and paired samples t-test where appropriate. Basal cervical widths for the estrogen and placebo groups were 4.4 +/- 0.7 and 3.7 +/- 0.7 mm, respectively (p < 0.01). Mean time required for dilatation of cervix was 44.4 +/- 16.2 seconds for the estrogen group and 61.4 +/- 18.3 seconds for the placebo group (p < 0.01). As a conclusion, misoprostol treatment alone is not effective to get cervical priming in postmenopausal women, and as shown in our study, pretreatment with local estrogen overcome the failure. To get a beneficial effect of misoprostol on cervical ripening, estrogenic activity is necessary and when pretreated with local estrogen, misoprostol ameliorates cervical priming in postmenopausal women.

    1985-01-01

    In a prospective, randomised study 40 primigravidae were treated intracervically with 0.05 mg or 0.1 mg Sulprostone-Tylose gel in order to soften the cervix prior to first trimester termination of pregnancy. Curettage was performed on the average 7.5 hours after prostaglandin administration. For objective demonstration of the priming effect, the force required for dilatation of the cervical canal was measured in Newtons by a special tonometer before prostaglandin application and before operation. The maximal dilatability with a force of 10 N, the increase in dilatability after local PG application, and the patency of the cervix were measured. The occurrence of PG-induced lower abdominal pain associated with contractions was analysed with regard to the number of episodes at pain, their timing and the required amount of analgesics. A modified visual analogue scale was used to evaluate the subjective pain experience. The abortive effect of 0.1 mg Sulprostone was found to be more efficient than the 0.05 mg dose. There was no statistical significant difference between the two doses, however, for the priming effect detectable with the tonometer. The subjective experience of pain, use of analgesics and the frequency of gastrointestinal side effects were significantly higher with 0.1 mg than with 0.05 mg Sulprostone. The visual analogue scale allows the patient to quantify, at least to some extent, her experience of pain, and enables a differentiated analgetic therapy. Because of its effectiveness and low rate of side effects, the intracervical application of 0.05 mg Sulprostone gel promises to be an advantageous alternative to other methods of cervical priming.

    Objective: To assess the rate of geographic miss on conventional radiotherapy planning of patients with cervical cancer, using magnetic resonance imaging. Materials and methods: Thirty-two patients with squamous cell carcinoma of the uterine cervix were studied. Magnetic resonance imaging of the pelvis was performed after clinical staging. Magnetic resonance imaging findings were compared with the classic fields described for the 'box' technique. Target volume within less than 1 cm margins of the fields' limits was considered as geographic miss. Results: Classical radiation field limits were inadequate in 24 cases (75%), all in the anterior (46%) or posterior (40%) border of the lateral fields. Conclusion: Magnetic resonance detected a high probability of geographic miss on conventional radiotherapy planning in this population, both in initial and advanced stages of the disease. (author)

    To understand the molecular mechanism of RB1 phosphorylation in basal-parabasal layers of normal cervix and during cervical cancer (CACX) development, we analyzed the alterations (expression/methylation/deletion/mutation) of RB1/phosphorylated RB1 (p-RB1) (ser807/811 and ser567) and two RB1 phosphorylation inhibitors, P16 and RBSP3, in disease-free normal cervical epithelium (n = 9), adjacent normal cervical epithelium of tumors (n = 70), cervical intraepithelial neoplasia (CIN; n = 28), CACX (n = 102) samples and two CACX cell lines. Immunohistochemical analysis revealed high/medium expression of RB1/p-RB1 (ser807/811 and ser567) and low expression of P16 and RBSP3 in proliferating basal-parabasal layers of majority of normal cervical epitheliums, irrespective of HPV16 infection. Interestingly, 35-52% samples showed high/medium expression of P16 in basal-parabasal layers of normal and had significant association with deleterious non-synonimous SNPs of P16. Methylation of P16 and RBSP3 in basal-parabasal layers of normal cervix (32 and 62%, respectively) showed concordance with their respective expressions in basal-parabasal layers. The methylation frequency of P16 and RBSP3 in basal-parabasal layers of normal did not change significantly in CIN and CACX. The deletion frequency of P16 and RB1 increased significantly with CACX progression. While, deletion of RBSP3 was high in CIN and comparable during CACX progression. P16 showed scattered and infrequent mutation in CACX. The alteration of P16 and RBSP3 was synergistic and showed association with overexpression of p-RB1 in tumors and associated with poor prognosis of patients. Thus, our data suggest that overexpression of p-RB1 in basal-parabasal layers of normal cervical epithelium was due to methylation/low functional-linked non-synonimous SNPs of P16 and RBSP3. This pattern was maintained during cervical carcinogenesis by additional deletion/mutation.

    Lately, a strong correlation has been established between diet and cancer. For ages, cumin has been a part of the diet. It is a popular spice regularly used as a flavoring agent in a number of ethnic cousins. In the present study, cancer chemopreventive potentials of different doses of a cumin seed-mixed diet were evaluated against benzo(a)pyrene [B(a)P]-induced forestomach tumorigenesis and 3-methylcholanthrene (MCA)-induced uterine cervix tumorigenesis. Results showed a significant inhibition of stomach tumor burden (tumors per mouse) by cumin. Tumor burden was 7.33 +/- 2.10 in the B(a)P-treated control group, whereas it reduced to 3.10 +/- 0.57 (P < 0.001) by a 2.5% dose and 3.11 +/- 0.60 (P <0.001) by a 5% dose of cumin seeds. Cervical carcinoma incidence, compared with the MCA-treated control group (66.67%), reduced to 27.27% (P < 0.05) by a diet of 5% cumin seeds and to 12.50% (P < 0.05) by a diet of 7.5% cumin seeds. The effect of 2.5 and 5% cumin seed-mixed diets was also examined on carcinogen/xenobiotic metabolizing phase I and phase II enzymes, antioxidant enzymes, glutathione content, lactate dehydrogenase (LDH), and lipid peroxidation in the liver of Swiss albino mice. Levels of cytochrome P-450 (cyt P-450) and cytochrome b5 (cyt b(5)) were significantly augmented (P < 0.05) by the 2.5% dose of cumin seed diet. The levels of cyt P-450 reductase and cyt b(5) reductase were increased (significance level being from P < 0.05 to P < 0.01) by both doses of cumin. Among the phase II enzymes, glutathione S-transferase specific activity increased (P < 0.005) by the 5% dose, whereas that of DT-diaphorase increased significantly (P < 0.05) by both doses used (2.5 and 5%). In the antioxidant system, significant elevation of the specific activities of superoxide dismutase (P < 0.01) and catalase (P < 0.05) was observed with the 5% dose of cumin. The activities of glutathione peroxidase and glutathione reductase remained unaltered by both doses of cumin. The level

    Full text: The objective of this study was to evaluate the levels of trace elements in blood sera of uterine cervix cancer patients, analyze their alteration with respect to healthy controls, ascertain the role played by them in the initiation, promotion and inhibition of cancer, and identify the best predictors amongst these for disease occurrence and progression. Moreover, the variation of trace elemental content in the sera of cervix cancer patients with the clinical stage of disease and with therapy was also studied. Particle induced X-ray emission (PIXE), a well established method for elemental analysis, was used in this work to identify and quantify trace elements in the blood sera of uterine cervix cancer subjects and healthy control subjects. The PIXE measurements were carried out using 2.5 MeV collimated proton beam from the 3 MV Tandem Pelletron Accelerator at lon Beam Laboratory, Institute of Physics, Bhubaneswar, India. Among all the trace elements identified in this work, statistically significant alterations in serum levels of copper, zinc, and selenium were observed among the various studied groups. The observed alterations are discussed with respect to the possible mechanisms by which these elements might influence the carcinogenic process. (author)

    Purpose: To evaluate and compare the efficacy of medium-dose-rate (MDR) and low-dose-rate (LDR) intracavitary brachytherapy (ICBT) for uterine cervical cancer. Methods and Materials: We evaluated 419 patients with squamous cell carcinoma of the cervix who were treated by radical radiotherapy with curative intent at Tokyo Women's Medical University from 1969 to 1999. LDR was used from 1969 to 1986, and MDR has been used since July 1987. When compared with LDR, fraction dose was decreased and fraction size was increased (1 or 2 fractions) for MDR to make the total dose of MDR equal to that of LDR. In general, the patients received a total dose of 60 to 70 Gy at Point A with external beam radiotherapy combined with brachytherapy according to the International Federation of Gynecology and Obstetrics stage. In the LDR group, 32 patients had Stage I disease, 81 had Stage II, 182 had Stage III, and 29 had Stage IVA; in the MDR group, 9 patients had Stage I disease, 19 had Stage II, 55 had Stage III, and 12 had Stage IVA. Results: The 5-year overall survival rates for Stages I, II, III, and IVA in the LDR group were 78%, 72%, 55%, and 34%, respectively. In the MDR group, the 5-year overall survival rates were 100%, 68%, 52%, and 42%, respectively. No significant statistical differences were seen between the two groups. The actuarial rates of late complications Grade 2 or greater at 5 years for the rectum, bladder, and small intestine in the LDR group were 11.1%, 5.8%, and 2.0%, respectively. The rates for the MDR group were 11.7%, 4.2%, and 2.6%, respectively, all of which were without statistical differences. Conclusion: These data suggest that MDR ICBT is effective, useful, and equally as good as LDR ICBT in daytime (about 5 hours) treatments of patients with cervical cancer.

    Epidemiological studies have demonstrated that cigarette smoking is an important cofactor or an independent risk factor for the development of cervical cancer. Benzo(a)pyrene (BaP) is one of the most potent tobacco smoke carcinogens in tobacco smoke. BaP induced DNA damage and over expression in p53 cervical tissue of mice as demonstrated in our previous study. Here we present the findings of exposure to BaP on the expression of Bcl-2, C-myc, Ki-67, Caspase-3 and Bax genes in mouse cervix. Acute intraperitoneal administration of BaP (12.5, 25, 50, 100mg/kg body weight) to ICR female mice induced a significant increase in Bcl-2, C-myc, Ki-67 mRNA and protein level till 72h except in Bcl-2 at 24h with 12.5, 25, 50mg/kg as well as at 48h with 12.5mg/kg body weight post treatment. A significant increase was also seen in Caspase-3 and Bax mRNA and protein level with peak level at 24h and gradual decrease till 72h, however, the expression of caspase-3 increased while that of Bax decreased with increasing dose of Bap after 24h. In sub chronic intraperitoneal and oral gavage administration of BaP (2.5, 5, 10mg/kg body weight), similar significant increase was observed for all the examined genes as compared to the control and vehicle groups, however the expression of Bax decreased in a dose dependent manner. The findings of this study will help in further understanding the molecular mechanism of BaP induced carcinogenesis of cervical cancer.

    Full Text Available Glassy cell carcinoma is a poorly differentiated variant of adenosquamous carcinoma of the cervix associated with an aggressive course and a poor prognosis. We present three cases of glassy cell carcinoma of the cervix. Patients presented with a cervical growth which was biopsied. Histology the tumours showed nests of cells with a granular or clear cytoplasm, displaying marked pleomorphism and mitoses. Stroma showed an eosinophilic infiltrate. Two tumours showed a pure glassy cell pattern and one showed glandular differentiation with intracellular and extracellular mucin. Patients were treated with a combination of surgery, radiotherapy and chemotherapy but showed a poor response. Two patients died of the disease of pelvic or distant metastases within two years of diagnosis and one was lost to follow up. Although glassy cell carcinoma runs an aggressive clinical course, an early diagnosis may help in a more effective management and offer a better prognosis.

    F-18 FDG PET is useful for monitoring residual or recurrent tumors after surgical resection. We describe five F-18 FDG PET images of three patients who had cervical carcinoma and then underwent a loop electro surgical excision procedure (LEEP). Two of the images were taken within 15 days and three at least 2 months after LEEP. The earlier F-18 FDG PET images revealed linear hypermetabolic lesions in the cervix that were produced by inflammation. This was confirmed by pathological analysis. The later F-18 FDG PET images did not reveal any remarkable hypermetabolism in the cervix without any treatment. These observations suggest that, to determine the response to LEEP therapy, F-18 FDG PET should not be performed within 15 days of the procedure.

    Full Text Available External beam radiotherapy (EBRT for carcinoma of uterine cervix is a basic line of treatment with three dimensional conformal radiotherapy (3DCRT in large number of patients. There is need for an established method for verification dosimetry. We tried to document absorbed doses in a group of carcinoma cervix patients by inserting a 0.6 cc Farmer type ion chamber in the vaginal cavity. A special long perspex sleeve cap is designed to cover the chamber for using in the patient′s body. Response of ionization chamber is checked earlier in water phantom with and without cap. Treatment planning was carried out with X-ray computed tomography (CT scan and with the chamber along with cap in inserted position, and with the images Xio treatment planning system. Three measurements on 3 days at 5-6 fraction intervals were recorded in 12 patients. Electrometer measured charges are converted to absorbed dose at the chamber center, in vivo. Our results show good agreement with planned dose within 3% against prescribed dose. This study, is a refinement over our previous studies with transmission dosimetry and chemicals in ampules. This preliminary work shows promise that this can be followed as a routine dose check with special relevance to new protocols in the treatment of carcinoma cervix with EBRT.

    A detailed examination of the cervical canal in the ewe was carried out. This analysis could be used to design new catheters for artificial insemination (AI) to achieve deeper cervical penetration and therefore better fertility results. Three hundred and sixty-five cervices from four sheep breeds (Churra, Assaf, Merino, Castellana) obtained postmortem were used. Cervix morphometry and depth of cervical penetration using two types of catheters were determined. A conventional straight catheter for ovine artificial insemination (IMV), and a bent catheter, ending in a stainless steel needle, 9 cm in length and with an 8 mm tip bent 45 degrees , were used. The results showed that the morphometry of the cervix depends on breed and age of the ewe. The cervices of Churra breed were shorter and narrower, and had a higher number of folds than those of other breeds. Postmortem cervical penetration was deeper when the cervices were longer and wider, and with fewer folds (Merino and Castellana breeds). In ageing ewes, the cervix tended to become longer and wider, with loose folds. This decreased structural complexity and significantly improved cervical penetration. The bent catheter allowed significantly greater cervical penetration than the straight IMV one.

    In a prospective, randomised study, 50 non-pregnant patients were treated intracervically with 3 ml 5% tylose, 50 micrograms sulprostone, 100 micrograms sulprostone gel, 3 ml 2.5 mM or 9.0 mM calcium chloride gel in order to soften the cervix 12-14 hours before diagnostic curettage. The gel was not used in a further 20 patients. To objectively demonstrate the priming effect, the force required for dilatation of the cervical canal was measured in Newtons, using a mechanical tonometer both before gel application and before the operation. In comparison with the administration of tylose only, the intracervical application of either sulprostone gel or calcium chloride gel led to a significant improvement in cervical dilatability. Tylose alone had a slight but measurable effect on the cervix. An increase in sulprostone from 50 micrograms to 100 micrograms or calcium molarity from 2.5 mM to 9.0 mM brought no further improvement in the dilatory effect. Dilatation-induced cervical lesions could be avoided by preoperative cervical ripening. After application of sulprostone, 3 out of 20 patients experienced doses-dependent uterine cramps, while all patients treated with calcium chloride gel were free of side effects. The intracervical administration of sulprostone and calcium chloride gel allowed gentle dilatation of the non-pregnant cervix, thus lowering the risk of uterine lesions. Under clinical aspects, cervical priming facilitates diagnostic and therapeutic procedures, which, in exceptional cases, can be performed without anaesthesia.

    Marked growth and softening of the uterine portion of the cervix occur during the last third of the 115-day gestation period in the gilt. These changes in the cervix are temporally correlated with elevated blood levels of relaxin, estrogen, and progesterone. We recently demonstrated that relaxin plays a major role in promoting both the growth and softening of the cervix that occur in pregnant gilts. The roles of estrogen and progesterone in these cervical changes remain poorly understood. Accordingly, this study determined the influence of relaxin, estrogen, and progesterone, individually and in combination, on cervical growth and softening in gilts. Fifteen days after ovariectomy, six to nine nonpregnant, sexually mature gilts were assigned to one of the following eight treatment groups: ovariectomized controls, relaxin treated, estrogen treated, progesterone treated, estrogen plus relaxin treated, progesterone plus relaxin treated, estrogen plus progesterone treated, and progesterone plus estrogen plus relaxin treated. Treatment was given for 10 days, with doses of relaxin (0.5 mg, four times daily), estradiol benzoate (1 mg, twice daily), and progesterone (50 mg, twice daily) selected to provide blood levels resembling those between days 100-110 of gestation. The growth, softening, and histological characteristics of the cervices were determined. Treatment with relaxin significantly increased the growth and softening and altered the histological characteristics of the uterine portion of the cervix in the absence of steroid treatment. Estrogen treatment alone increased cervical growth, but when given in combination with relaxin, estrogen did not augment relaxin's ability to increase either cervical growth or softening. Progesterone alone had little or no effect on the growth or softening of the uterine portion of the cervix. Unexpectedly, when given in combination with relaxin, progesterone augmented markedly relaxin's effects on softening and alteration of the

    Full Text Available Filaggrin proteins are expressed in the skin, oral cavity, oesophagus, and cervical mucose. Loss-of-function mutations in the filaggrin gene (FLG reduce filaggrin expression and cause an impaired skin barrier function. We hypothesized that FLG mutation carriers would be more susceptible to human papillomavirus (HPV infection and thus a higher risk of HPV-related cancer and pre-cancer. We investigated the association of the FLG genotype with incidence of HPV-related cancer of cervix, vagina, vulva, penis, anus and head and neck, and pre-cancer of the cervix.We included 13,376 persons from four population-based studies conducted in the same background population in Copenhagen, Denmark. Participants were genotyped for the most common FLG mutations in Europeans. Information on cancer was obtained from The Danish Cancer Registry until 11 July 2011.There were 489 cases of prevalent and 97 cases of incident HPV-related cancer and pre-cancer (median follow-up 11.5 years. There was a statistically significant association between FLG genotype and incident HPV-related cancer and pre-cancer with a hazard ratio, HR = 2.1 (95% confidence intervals, CI: 1.2, 3.7 for FLG mutation carriers vs. wild types.FLG loss-of-function mutations were associated with higher incidence of HPV-related cancers and pre-cancers that are potentially screening and vaccine preventable.

    A cancer needs assessment, funded by the National Cancer Institute, was conducted in Pohnpei State (Pohnpei), Federated States of Micronesia (FSM). Findings revealed that cancer is the third leading cause of death in Pohnpei, yet cancer-related awareness, prevention, detection, and treatment services are limited. A number of needs were identified, and an action plan was developed based on five priority areas: 1) increasing community awareness about cancer (especially, cervix, breast, liver and lung) and related risk factors; 2) securing funding for cancer prevention and control planning and activities; 3) establishing a fully staffed cancer prevention and control office; 4) building local capacity for cancer cytology; and 5) increasing capacity to obtain and process lab specimens for high-risk patients.

    Full Text Available There are many carcinogenetic elements in industry and it is for this reason that study and research concerning the effect of these materials is carried out on a national and international level. The establishment and growth of cancer are affected by different factors in two main areas:-1 The nature of the human or animal including sex, age, point and method of entry, fat metabolism, place of agglomeration of carcinogenetic material, amount of material absorbed by the body and the immunity of the body.2 The different nature of the carcinogenetic material e.g. physical, chemical quality, degree of solvency in fat and purity of impurity of the element. As the development of cancer is dependent upon so many factors, it is extremely difficult to determine whether a causative element is principle or contributory. Some materials are not carcinogenetic when they are pure but become so when they combine with other elements. All of this creates an industrial health problem in that it is almost impossible to plan an adequate prevention and safety program. The body through its system of immunity protects itself against small amounts of carcinogens but when this amount increases and reaches a certain level the body is not longer able to defend itself. ILO advises an effective protection campaign against cancer based on the Well –equipped laboratories, Well-educated personnel, the establishment of industrial hygiene within factories, the regular control of safety systems, and the implementation of industrial health principles and research programs.

    Full Text Available INTRODUCTION. The incidence of cancer among residents in sites contaminated by pollutants with a possible health impact is not adequately studied. In Italy, SENTIERI Project (Epidemiological study of residents in National Priority Contaminated Sites, NPCSs was implemented to study major health outcomes for residents in 44 NPCSs. METHODS. The Italian Association of Cancer Registries (AIRTUM records cancer incidence in 23 NPCSs. For each NPCSs, the incidence of all malignant cancers combined and 35 cancer sites (coded according to ICD-10, was analysed (1996-2005. The observed cases were compared to the expected based on age (5-year period,18 classes, gender, calendar period (1996-2000; 2001-2005, geographical area (North-Centre and Centre-South and cancer sites specific rates. Standardized Incidence Ratios (SIR with 90% Confidence Intervals were computed. RESULTS. In both genders an excess was observed for overall cancer incidence (9% in men and 7% in women as well as for specific cancer sites (colon and rectum, liver, gallbladder, pancreas, lung, skin melanoma, bladder and Non Hodgkin lymphoma. Deficits were observed for gastric cancer in both genders, chronic lymphoid leukemia (men, malignant thyroid neoplasms, corpus uteri and connective and soft-tissue tumours and sarcomas (women. DISCUSSION. This report is, to our knowledge, the first one on cancer risk of residents in NPCSs. The study, although not aiming to estimate the cancer burden attributable to the environment as compared to occupation or life-style, supports the credibility of an etiologic role of environmental exposures in contaminated sites. Ongoing analyses focus on the interpretation of risk factors for excesses of specific cancer types overall and in specific NPCSs in relation to the presence of carcinogenic pollutants.

    A number of genes and their products are induced early or late following exposure of cells to ionizing radiation. These radiation-induced genes have various effects of irradiated cells and tissues. Suppression subtractive hybridization (SSH) based on PCR was used to identify the differentially expressed genes by radiation in cervix carcinoma cells. Total RNA and poly (A){sup +} mRNA were isolated from irradiated and non-irradiated HeLa cells. Forward-and reverse-subtracted cDNA libraries were constructed using SSH. Eighty-eight clones of each were used to randomly select differentially expressed genes using reverse Northern blotting (dot blot analysis). Northern blotting was used to verify the screened genes. Of the 176 clones, 10 genes in the forward-subtracted library and 9 genes in the reverse-subtracted library were identified as differentially expressed radiation-induced genes by PCR-select differential screening. Three clones from the forward-subtracted library were confirmed by Northern blotting, and showed increased expression in a dose-dependent manner, including a telomerase catalytic subunit and sodium channel-like protein gene, and an ESTs (expressed sequence tags) gene. We identified differentially expressed radiation-induced genes with low-abundance genes with SSH, but further characterization of theses genes are necessary to clarify the biological functions of them.

    Ninety-two consecutive patients with stages IB and IIA carcinoma of the cervix were treated by one of two regimens: pre-operative intracavitary caesium-137 followed by a Wertheim hysterectomy (group 1) or staging laparotomy with biopsy of suspicious lymph nodes (group 2) (if there was no evidence of tumour on examination of a frozen section of the lymph nodes a Wertheim hysterectomy was performed, but if a tumour was present the abdomen was closed and a course of radical irradiation given). When there was evidence of extracervical spread on examination of the specimen after the Wertheim hysterectomy, postoperative irradiation was given. It was found that clinical staging had been incorrect in 38.5% of patients thought to have stage IB disease and in 71.4% of those thought to have stage IIA disease. The actuarial survival curves showed no significant statistical difference between group 1 and group 2. When examination of the operative specimen showed tumour invasion of the parametrium only, the disease was well controlled by postoperative irradiation (all 7 such patients survived). On the other hand, when there was evidence of tumour invasion of pelvic lymph nodes the 4-year survival rate fell to 31% (4 out of 13 patients), despite the use of postoperative irradiation.

    Pemphigus vulgaris (PV) is a rare mucocutaneous disease caused by the abnormal production of antibodies against epithelial cell surface glycoproteins, resulting in loss of cell adhesion and intraepithelial blister formation. Cervical involvement in PV has been poorly reported, and there is little information regarding the criteria about consequential cytological changes identified in a Papanicolaou-stained cervicovaginal smear (Pap smear). Here, we report a case of PV manifesting in the cervix as well as the difficulty associated with the cytomorphological identification and interpretation of acantholytic cells. This case involved a 40-year-old patient with no history of Pap test abnormalities and no prior diagnosis of PV. In the cytological assessment, cells were identified both in isolation and in clusters that exhibited round nuclei of increased volume, inconspicuous nucleoli, and perinuclear halos. The patient underwent a cervical biopsy that revealed vesiculobullous lesions and morphological pattern consistent with PV. A skin biopsy confirmed this diagnosis. We concluded that knowledge of PV cytomorphology is important because difficulties associated with the identification and interpretation of acantholytic cells might be responsible for false positive diagnoses of cervical neoplasia. However, a suspected diagnosis of PV is possible if the cytological findings are carefully correlated with the clinical data.
