    A major problem with cervical cancer screening in countries which have no organized national screening program for cervical cancer is suboptimal participation. Implementation of selfsampling method may increase the coverage. We determined the agreement of cytological diagnoses made on samples collected by women themselves (selfsampling) versus samples collected by physicians (Physician sampling). We invited women volunteers to undergo two procedures; cervical selfsampling using the Evalyn brush and physician sampling using a Cervex brush. The women were shown a video presentation on how to take their own cervical samples before the procedure. The samples taken by physicians were taken as per routine testing (Gold Standard). All samples were subjected to Thin Prep monolayer smears. The diagnoses made were according to the Bethesda classification. The results from these two sampling methods were analysed and compared. A total of 367 women were recruited into the study, ranging from 22 to 65 years age. There was a significant good agreement of the cytological diagnoses made on the samples from the two sampling methods with the Kappa value of 0.568 (p=0.040). Using the cytological smears taken by physicians as the gold standard, the sensitivity of selfsampling was 71.9% (95% CI:70.972.8), the specificity was 86.6% (95% CI:85.7 87.5), the positive predictive value was 74.2% (95% CI:73.375.1) and the negative predictive value was 85.1% (95% CI: 84.286.0). Selfsampling smears (22.9%) allowed detection of microorganisms better than physicians samples (18.5%). This study shows that samples taken by women themselves (selfsampling) and physicians have good diagnostic agreement. Selfsampling could be the method of choice in countries in which the coverage of women attending clinics for screening for cervical cancer is poor.

    Full Text Available The estimated burden of neoplasia of uterine cervix in the 27 EU member states sums up to 34300 cases and 16200 death, with higher incidence and mortality in eastern countries. A number of risk factors increase the likelihood of developing cervical cancer. Even if the risk factors significantly increase the chances of developing cervical cancer, a large number of women with risk factors do not develop the disease, and when a woman develops cancer or precancerous lesions in the cervix may be difficult to establish the causal relationship with certain risk factors. The present study aimed to appreciate the presence and magnitude of risk factors for patients diagnosed with advanced cervical cancer and to outline best strategies to reduce the incidence of this neoplasia, and improve prognosis. Risk factors have been investigated in 42 patients diagnosed with advanced cervical cancer using HPV genotyped determination and a questionnaire for the evaluation of cervical cancer risk factors. In our sample of patients a high risk profile is shaping for low socio-economical level, modulated by the impact of HPV infection with high risk stains of virus, overweight-obesity, smoking and inadequate cervical cancer screening. In this frame a special alarm signal is represented by the very high percentage of patients with overweight and obesity. From the public health perspective, we consider that efforts should be focused on preventing weight gain, regular screening and health education field.

    Background: The rate of uptake of the Papanicolaou (Pap) smear is generally low. Its causal relationship with human papillomavirus (HPV) DNA allows HPV DNA self-sampling to be used as an alternative screening tool for cervical cancer. Objectives: This study explored the acceptability of HPV DNA self-sampling and its impact on the rate of compliance with cervical cancer screening. Methods: A crossover randomized clinical trial was conducted in community-based clinics. Participants were allocated to 1 of the following 2 arms: arm 1: self-sampling before a Pap smear; and arm 2: a Pap smear before self-sampling. After completing the 2 screening methods, participants in each arm took part in face-to-face interviews using standardized, structured questionnaire. Results: The participants accepted both self-sampling (7.7/10) and a Pap smear (7.8/10) for cervical cancer screening. However, participants without previous experience of Pap smears or who had more than 2 sexual partners preferred self-sampling (P cervical cancer screening by 6.5% and would entail lower costs. Conclusion: Human papillomavirus DNA self-sampling could be an alternative screening method to increase the coverage of cervical cancer screening. Implications for Practice: Human papillomavirus DNA self-sampling could overcome the barriers raised by Pap smears and enhance the coverage of cervical cancer screening. Promotional publicity and education are essential. PMID:25730587

    We compared the self-sampling performance of the newly designed HerSwab™ device with a physician-collected cervical sample and another self-sample using the cobas® PCR Female swab for the detection of cervical intraepithelial neoplasia (CIN) and cancer. Women referred for colposcopy at McGill University affiliated hospital clinics collected two consecutive self-samples, one with HerSwab™ and one with cobas® swab, after receiving instructions. The order of sampling was randomized. The colposcopist then collected a cervical sample and conducted a colposcopic examination. Samples were tested for human papillomavirus (HPV) DNA. Sensitivity and specificity to detect CIN2+ and respective 95% confidence intervals (CI) were calculated to compare sampling approaches. The HPV testing agreement between samples was measured using the Kappa statistic. Of 1217 women enrolled, 1076 had complete results for HPV and cytology; 148 (13.8%) had CIN1, 147 (13.7%) had CIN2/3, and 5 (0.5%) had cancer. There was very good agreement between methods for HPV detection (HerSwab™ versus physician: kappa=0.84; cobas® swabs versus physician: kappa=0.81; HerSwab™ versus cobas® swabs: kappa=0.87). The sensitivity of HPV detection for CIN2+ was 87.6% (95%CI: 79.8-93.2) with self-sampling using HerSwab™, 88.6% (95%CI: 80.9-94.0) with self-sampling using the cobas® swab, and 92.4% (95%CI: 85.5-96.7) with physician sampling. Corresponding estimates of specificity were 58.1% (95%CI: 54.1-62.1), 55.0% (95%CI: 50.9-59.0) and 58.7% (95%CI: 54.6-62.6). Cytology (ASC-US or more severe) done on the physician-collected specimen was 80.2% (95%CI: 70.8-87.6) sensitive and 61.4% (95%CI: 57.2-65.5) specific for CIN2+. The HerSwab™ had good agreement with physician sampling in detecting HPV, and adequate performance in detecting high-grade lesions among women referred to colposcopy for abnormal cytology.

    Cervical cancer is highly preventable and treatable if detected early through regular screening. Women in the Canadian province of Newfoundland & Labrador have relatively low rates of cervical cancer screening, with rates of around 40 % between 2007 and 2009. Persistent infection with oncogenic human papillomavirus (HPV) is a necessary cause for the development of cervical cancer, and HPV testing, including self-sampling, has been suggested as an alternative method of cervical cancer screening that may alleviate some barriers to screening. Our objective was to determine whether offering self-collected HPV testing screening increased cervical cancer screening rates in rural communities. During the 2-year study, three community-based cohorts were assigned to receive either i) a cervical cancer education campaign with the option of HPV testing; ii) an educational campaign alone; iii) or no intervention. Self-collection kits were offered to eligible women at family medicine clinics and community centres, and participants were surveyed to determine their acceptance of the HPV self-collection kit. Paired proportions testing for before-after studies was used to determine differences in screening rates from baseline, and Chi Square analysis of three dimensional 2 × 2 × 2 tables compared the change between communities. Cervical cancer screening increased by 15.2 % (p cancer screening rate in a rural NL community. Women who completed self-collection had generally positive feelings about the experience. Offering HPV self-collection may increase screening compliance, particularly among women who do not present for routine Pap smears.

    There is an increasing need for the establishment of a cervical cancer bio-bank that will facilitate both clinical and basic research. The cervical cancer bio-bank was first established in January 1999 and included two stages. First, a GWAS-based sample collection was conducted with special emphasis on the diagnosis and the retrieval of the corresponding bio-specimens, especially blood samples. Second, clinical data and their corresponding bio-specimens were routinely collected and handled. Notably, these bio-specimens also included samples from Wufeng Tujia Autonomous County, which has the highest incidence of cervical cancer in China. The specimens were collected from patients with cervical cancer and those with cervical intraepithelial neoplasia, while the control samples were collected from normal individuals. With special emphasis on clinical data and blood samples for the GWAS analysis, the collection of other bio-specimens was slow, and the pairing of specimens and clinical data was poor during the first stage. However, in the second stage, the pairing of the clinical data and its corresponding bio-specimens improved. At present, the samples procured and preserved in the bio-bank cover most regions of China and different ethnic groups for both the normal controls and cervical cancer patients of different pathological categories. This bio-bank of cervical cancer specimens from the Chinese population will greatly promote the studies of cervical cancer in China.

Self-sampled specimens were split and analyzed for the presence of high-risk (hr HPV by the CLART® HPV2 test and the digene® Hybrid Capture (HC2 test. The control group consisted of 2593 women who received a 2nd reminder letter according to the current guidelines of the NCCSP. The attendance rates were 33.4% in the intervention group and 23.2% in the control group, with similar attendance rates for both self-sampling devices. Women in the self-sampling subgroup responded favorably to both self-sampling devices and cited not remembering receiving a call for screening as the most dominant reason for previous non-attendance. Thirty-two of 34 (94.1% hrHPV-positive women in the self-sampling subgroup attended follow-up. In conclusion, self-sampling increased attendance rates and was feasible and well received. This study lends further support to the proposal that self-sampling may be a valuable alternative for increasing cervical cancer screening coverage in Norway.

    In most industrialized countries, screening programs for cervical cancer have shifted from cytology (Pap smear or ThinPrep) alone on clinician-obtained samples to the addition of screening for human papillomavirus (HPV), its main causative agent. For HPV testing, self-sampling instead of clinician-sampling has proven to be equally accurate, in particular for assays that use nucleic acid amplification techniques. In addition, HPV testing of self-collected samples in combination with a follow-up Pap smear in case of a positive result is more effective in detecting precancerous lesions than a Pap smear alone. Self-sampling for HPV testing has already been adopted by some countries, while others have started trials to evaluate its incorporation into national cervical cancer screening programs. Self-sampling may result in more individuals willing to participate in cervical cancer screening, because it removes many of the barriers that prevent women, especially those in low socioeconomic and minority populations, from participating in regular screening programs. Several studies have shown that the majority of women who have been underscreened but who tested HPV-positive in a self-obtained sample will visit a clinic for follow-up diagnosis and management. In addition, a self-collected sample can also be used for vaginal microbiome analysis, which can provide additional information about HPV infection persistence as well as vaginal health in general.

    African Journals Online (AJOL)

    Cervical cancer remains the most common cancer diagnosed in women in southern Africa, with an estimated lifetime risk of 1 in. 26.1. Unfortunately most of these cancers are also diagnosed at a late stage, with subsequent poor prognosis for long-term survival. This very high incidence is particularly sad in an era where.

    Purpose: To elucidate changes in gene expression after treatment with regional thermochemoradiotherapy in locally advanced squamous cell cervical cancer. Methods and Materials: Tru-Cut biopsy specimens were serially collected from 16 patients. Microarray gene expression levels before and 24 h after the first and second trimodality treatment sessions were compared. Pathway and network analyses were conducted by use of Ingenuity Pathways Analysis (IPA; Ingenuity Systems, Redwood City, CA). Single gene expressions were analyzed by quantitative real-time reverse transcription-polymerase chain reaction. Results: We detected 53 annotated genes that were differentially expressed after trimodality treatment. Central in the three top networks detected by IPA were interferon alfa, interferon beta, and interferon gamma receptor; nuclear factor κB; and tumor necrosis factor, respectively. These genes encode proteins that are important in regulation cell signaling, proliferation, gene expression, and immune stimulation. Biological processes over-represented among the 53 genes were fibrosis, tumorigenesis, and immune response. Conclusions: Microarrays showed minor changes in gene expression after thermochemoradiotherapy in locally advanced cervical cancer. We detected 53 differentially expressed genes, mainly involved in fibrosis, tumorigenesis, and immune response. A limitation with the use of serial biopsy specimens was low quality of ribonucleic acid from tumors that respond to highly effective therapy. Another 'key limitation' is timing of the post-treatment biopsy, because 24 h may be too late to adequately assess the impact of hyperthermia on gene expression.

    Full Text Available Background Cervical cytology for uterine cervical cancer screening has transitioned from conventional smear (CS to liquid-based cytology (LBC, which has many advantages. The aim of this study was to compare the proportion of unsatisfactory specimens from CS versus LBC at multiple institutions including general hospitals and commercial laboratories. Methods Each participating institution provided a minimum of 500 Papanicolaou (Pap test results for analysis. Pap tests were classified according to the participating institution (commercial laboratory or general hospital and the processing method (CS, ThinPrep, SurePath, or CellPrep. The causes of unsatisfactory results were classified as technical problems, scant cellularity, or complete obscuring factors. Results A total of 38,956 Pap test results from eight general hospitals and three commercial laboratories were analyzed. The mean unsatisfactory rate of LBC was significantly lower than that of CS (1.26% and 3.31%, p = .018. In the LBC method, samples from general hospitals had lower unsatisfactory rates than those from commercial laboratories (0.65% vs 2.89%, p = .006. The reasons for unsatisfactory results were heterogeneous in CS. On the other hand, 66.2% of unsatisfactory results in LBC were due to the scant cellularity. Conclusions Unsatisfactory rate of cervical cancer screening test results varies according to the institution and the processing method. LBC has a significantly lower unsatisfactory rate than CS.

    Limited data suggested that the prevalence of Human Papillomavirus (HPV) among female sex workers (FSW) is much higher than in the general female population. The current study aimed to examine the HPV and cervical cancer related awareness, knowledge, and behaviors among FSW in China. A total of 360 FSW recruited from entertainment establishments in Beijing completed a self-administered survey including demographics, HPV related knowledge, and health-seeking and cervical cancer preventive behaviors. Approximately 70.8% of the participants ever heard of cervical cancer, and as few as 22.1% and 13.3% ever heard of HPV and HPV vaccine, respectively. The mean score on a 7-item knowledge scale was 2.2 (SD = 2.4). Less than 10% of FSW perceived any risk of cervical cancer, and only 15.3% ever had a Pap smear. About 40.8% of FSW would accept HPV vaccine if it is free, and 21.8% would accept it even with a charge. Multivariate regression suggested that women with better knowledge of cervical cancer were more likely to have a Pap smear (aOR = 1.35); women who had tested for HIV were 11 times more likely to have a Pap smear, and women who had worked longer in commercial sex (aOR = 1.01) and had regular health check-ups (aOR = 1.95) were more likely to accept HPV vaccine. Our study underscores the needs for effective cervical cancer prevention programs for FSW in China and other resource-limited countries. We specifically call for cervical cancer and HPV knowledge and awareness programs and regular screening as well as HPV risk-reduction programs for these vulnerable women.

    Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    To develop and implement a community based model for cervical cancer prevention that allows the communities to manage the screening and the healthcare system to focus resources on evaluation and management of the positives. Using self-sampling and the concepts founded in Community Based Participatory Research (CBPR), we progressively developed a model to efficiently reach the women, especially rural communities; and collect the volume of samples needed to support high throughput centralized low cost per case processing. 8382 eligible women, ages 35 to 59, in 130 rural communities participated. The screening was organized by the local government administration and conducted by the community leaders (CLs). The model used was progressively designed through detailed assessment of key elements at 6 decision points in 26 workshops that were used to train the CLs and the local promoters. The communities were able to accurately conduct the screening; in the final model a local medical worker conducted a 50-minute workshop featuring instructional posters and structured role-play. A manual and a workshop DVD were created for distribution to and implementation by local governments. The average callback rate was 84.3%, without involvement of the local doctors in the management of the positives. An efficient community based model capable of massive screening events was developed. We believe that the callback rate will be further improved when local doctors are trained in the management of the positives. Many elements impact coverage and further research is needed to define the influence of the identified key variables. Copyright © 2014 Elsevier Inc. All rights reserved.

    Cervical cancer is the fourth most common malignancy diagnosed in women worldwide. Nearly all cases of cervical cancer result from infection with the human papillomavirus, and the prevention of cervical cancer includes screening and vaccination. Primary treatment options for patients with cervical cancer may include surgery or a concurrent chemoradiotherapy regimen consisting of cisplatin-based chemotherapy with external beam radiotherapy and brachytherapy. Cervical cancer causes more than one quarter of a million deaths per year as a result of grossly deficient treatments in many developing countries. This warrants a concerted global effort to counter the shocking loss of life and suffering that largely goes unreported. This article provides a review of the biology, prevention, and treatment of cervical cancer, and discusses the global cervical cancer crisis and efforts to improve the prevention and treatment of the disease in underdeveloped countries.

    Background Hispanic women have a higher incidence of cervical cancer than all other races and ethnicities. In Hispanic subgroups, Mexican American women were among the least likely to have received cervical cancer screening. In a recent RCT, Ayudando a las Mujeres con Información, Guia, y Amor para su Salud (AMIGAS) was shown to increase cervical cancer screening rates among women of Mexican descent at 6 months in all intervention arms compared to the control arm. Limited information exists about the economics of interventions to increase cervical cancer screening rates among women of Mexican descent. Purpose This study aims to estimate the cost-effectiveness of the alternative AMIGAS intervention methods for increasing cervical cancer screening among low-income women of Mexican descent in three U.S. communities. Methods Cost data were collected from 2008 to 2011 alongside the AMIGAS study of 613 women. Receipt of Pap test within 6 months of intervention was the primary outcome measure in the cost-effectiveness analysis, conducted during 2012–2013. Results The cost per additional woman screened comparing the video-only intervention to usual care was $980. The cost increased to $1,309 with participant time cost included. With an additional cost per participant of $3.90 compared to flipchart only, the full AMIGAS program (video plus flipchart) yielded 6.8% additional women screened. Conclusions Results on the average and incremental cost-effectiveness of the AMIGAS program elements may assist health policymakers and program managers to select and appropriately budget for interventions shown to increase cervical cancer screening among low-income women of Mexican descent.

    In order to observe the radiobiological characteristics of cervical cancer, the author carried out irradiation of 60 Co in 16 cases of cervical cancer. The primary lesion of each case was exposed to radiation of 100 R once a day, 40 times in sequence, totaling 4,000 R. To evaluate this results, the vaginal smears were obtained everyday and examined for changes in cancerous cells caused by the irradiation. The results of our study showed that cervical cancer could be classified into three groups according to the radiosensitivity of its cancerous cells. In the group of low-radiosensitivity (11 cases of 16), the cancerous cells decreased gradually, and enlargement of the nuclei of the cancerous cells was observed from 2,000 R of irradiation, but the majority of the cancerous cells were those of nucleus after the irradiation of 4,000 R. In all of the 5 uterus removed, residual cancer lesion was noted. The radiocuability was unfavourable. In the group of high-radiosensitivity (4 cases of 16), the cancerous cells decreased remarkablly. Enlargement of nucleus was noted from 1,000 R of the irradiation, the cancerous cells of small-sized nucleus appeared with the irradiation of 3,000 R but the cancerous cells almost disappeared with the irradiation of 4,000 R. The radiocuability was favourable. In the group of combination of high-radiosensitivity and low-radiosensitivity portions (one case of 16), the cancerous cells decreased remarkablly until the exposure to the radiation of 2,000 R but thereafter did slowly. In a removed uterus, the cancer lesion was noted, but the prognosis was favourable. The foregoing results suggest that changes in the nuclear diameter of the cancerous cells in vaginal smears during irradiation can tell the radiosensitivity of the cancerous cells. (Kanao, N.)

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

    Peroxisome proliferator-activated receptor gamma (PPAR γ) is activated by thiazolidinedione drugs (TZDs) and can promote anti-cancer properties. We used three TZDs (pioglitazone, rosiglitazone, and ciglitazone) to target cervical cancer cell lines and a nude mouse animal model. Each agent increased activation of PPAR γ, as judged by a luciferase reporter gene assay in three HPV-associated cell lines (CaSki, SiHa, and HeLa cells) while decreasing cellular proliferation in a dose-dependent manner. They also promoted Oil Red O accumulation in treated cell lines and upregulated the lipid differentiation marker adipsin. Interestingly, xenograft HeLa tumors in nude mice treated with 100 mg/kg/day pioglitazone exhibited decreased growth compared to control mice or mice treated with standard cervical chemotherapy. In conclusion, TZDs slow tumor cell growth in vitro and in vivo with decreases in cell proliferation and increases in PPAR γ and adipsin. These agents may be interesting treatments or treatment adjuncts for HPV-associated cancers or perhaps even precancerous conditions. - Highlights: • Thiazolidinediones decreases cervical cancer proliferation. • Pioglitazone increases cervical cancer differentiation. • Pioglitazone decreases tumor growth in mice. • Pioglitazone may be a useful treatment adjunct.

    The present study was designed to ascertain knowledge about HPV, cervical cancer (CC) and the Pap test among female dental students of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India. A self-administered questionnaire covering demographic details, knowledge relating to human papilloma virus (HPV) (8 items), cervical cancer (4 items) and the Pap smear (6 items) was employed. Responses were coded as "True, False and Don't Know". Mean and standard deviation (SD) for correct answers and levels of knowledge were determined. Based on the year of study, significant differences in knowledge of HPV were noted for questions on symptoms (p=0.01); transmission from asymptomatic partners (p=0.002); treatment with antibiotics (p=0.002); start of sexual activity (p=0.004); and recommended age for HPV vaccination (p=0.01). For knowledge regarding CC, significance was observed for the age group being affected (p=0.008) and symptoms of the disease in early stages (p=0.001). Indications for Pap smear tests like symptoms' of vaginal discharge (p=0.002), marital status (p=0.01) and women with children (p=0.02) had significant difference based on the year of study. Based on religion, transmission of HPV via pregnancy, HPV related diseases except CC and preventive measures except condom use and oral contraceptives showed significant differences. However, significant variation with religion was observed only for two preventive measures of CC (Pap test; p=0.004) and HPV vaccination (p=0.003). Likewise, only the frequency of Pap test showed a significant difference for religion (p=0.001). This study emphasizes the lack of awareness with regard to HPV, CC and screening with pap smear even among health professionals. Hence, regular health campaigns are essential to reduce the disease burden.

    While (Pap)anicolaou screening has helped to decrease cervical cancer incidence in Canada, First Nations women continue to have a higher burden and mortality relative to mainstream populations. Many First Nations women may feel uncomfortable with the invasiveness of this test, contributing to this statistic. Implemented from 2009 to 2015 in 10 Northwest Ontario First Nations communities, the Anishinaabek Cervical Cancer Screening Study (ACCSS) uniquely addressed this Indigenous health inequity through a mixed methods approach. Our goal was to offer an alternative test which the women could do themselves: human papillomavirus (HPV) testing based on self-sampling. We investigated whether First Nations women preferred HPV self-sampling over healthcare provider (HCP)-administered Pap screening. Participatory action researchinformed by the ethical space concept has guided all stages of the ACCSS. We conducted qualitative interviews with 16 HCPs and 8 focus group discussions with 69 female community members followed by a cluster-randomised controlled trial (RCT). Here, we draw on the qualitative field data and an end-of-study community update gathering to disseminate and contextualise research findings. Informant data were evaluated using thematic analysis. We discuss factors influencing participants' strong preference for HPV self-sampling over physician-conducted Pap screening. Key arguments included enhanced accessibility and more personal control, less physical and emotional discomfort and fewer concerns regarding privacy of test results. For future implementation of HPV self-sampling, study participants emphasised the need for more culturally sensitive education addressed to community members of all genders, starting at school, clarifying that HPV causes cervical cancer. Further, HPV infection should be de-stigmatised by accentuating that it affects men and women alike. Here we show that self-sampling in conjunction with community engagement and culturally sensitive

    Objective: The objective of the study was to determine what women being treated for HIV and AIDS at a specific healthcare centre in Johannesburg knew about cervical cancer and cervical screening. Method: A survey design was used, with data gathered by means of a self-administered questionnaire. Convenience sampling selected 315 women to participate (n = 315. Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.

  16. Preventive vaccines for cervical cancer

    Full Text Available The potential use of vaccines for the human papillomavirus (HPV in the prevention and treatment of cervical cancer is a possibility in the near future. Close to 20 genotypes of HPV, of the 75 that have been identified, infect the femine genital tract, but four subtypes (16, 18, 31 and 45 have been associated in close to 80% of cervical cancers. this article proposes that in order to design an effective prophylactic vaccine against HPV infection, an adequate immune response should be guaranteed through four goals; a activation of antigens present in the cell; b overcoming the host response and viral genetic variability in the T cell response; c generation of high levels of T and B memory cells; and d persistence of antigens.

    Molecular, clinical and epidemiological studies have established beyond doubt that human papiloma viruses (HPV) cause cervical cancer. The virus is also associated with genital warts and other less common cancers in oropharynx, vulva, vagina and penis. Worldwide, VPH genotypes 16 and 18 are the most common high risk genotypes, detected in near 70% of women with cervical cancer. The discovery of a cause-effect relationship between several carcinogenic microorganisms and cancer open avenues for new diagnostic, treatment and prevention strategies. In this issue of Revista Médica de Chile, two papers on HPV are presented. Guzman and colleagues demonstrate that HPV can be detected in 66% to 77% of healthy male adolescents bypolymerase chain reaction and that positivity depends on the site of the penis that is sampled. These results support the role of male to female transmission of high risk HPVs in Chile and should lead to even more active educational campaigns. The second paper provides recommendations for HPV vaccine use in Chile, generated by the Immunization Advisory Committee of the Chilean Infectious Disease Society. To issue these recommendations, the Committee analyzes the epidemiological information available on HPV infection and cervical cancer in Chile, vaccine safety and effectiveness data, and describes cost-effectiveness studies. Taking into account that universal vaccination is controversial, the Committee favors vaccine use in Chile and it's incorporation into a national program. However, there is an indication that the country requires the implementation of an integrated surveillance approach including cross matching of data obtained from HPV genotype surveillance, monitoring of vaccination coverage, and surveillance of cervical cancer. The final decision of universal vaccine use in Chile should be based on a through analysis of information.ev Mid Chile

    Earlier diagnosis of cancer has become a policy priority. There is evidence that minority ethnic groups are more likely to delay help-seeking for cancer symptoms, but few studies have explored reasons for delay in these groups. The present study explored facilitators and barriers to help-seeking for breast and cervical cancer in an ethnically diverse sample of women. Semi-structured interviews were carried out with 54 healthy women from a range of ethnic backgrounds; Indian, Pakistani, Bangladeshi, Caribbean, African, Black British, Black other, White British and White other. Framework analysis was used to identify themes. Appraising a symptom as possibly due to cancer was an important facilitator of help-seeking, although for some the prospect of a cancer diagnosis was a deterrent. Women believed that earlier diagnosis improved the chance of survival, and this facilitated prompt help-seeking. A sympathetic GP facilitated help-seeking, and an unsympathetic GP was a deterrent. Some ethnic minority women described the use of alternative medicine and prayer as a first-line strategy that might delay help-seeking. Language barriers, racism and a tendency to 'soldier on' were also mentioned by these women. Models of delay in presentation for early cancer symptoms are likely to transfer across different ethnic groups. Encouraging open discussion about cancer among minority communities could help raise awareness about the importance of early detection and promote help-seeking as a priority response to a possible cancer symptom. © 2013 The Authors.

    Cervical cancer is a major disease with high mortality. All cervical cancers are caused by infection with human papillomaviruses (HPV). Although preventive vaccines for cervical cancer are successful, treatment of cervical cancer is far less satisfactory because of multidrug resistance and side effects. In this review, we summarize the recent application of nanotechnology to the diagnosis and treatment of cervical cancer as well as the development of HPV vaccines. Early detection of cervical cancer enables tumours to be efficiently removed by surgical procedures, leading to increased survival rate. The current method of detecting cervical cancer by Pap smear can only achieve 50% sensitivity, whereas nanotechnology has been used to detect HPVs with greatly improved sensitivity. In cervical cancer treatment, nanotechnology has been used for the delivery of anticancer drugs to increase treatment efficacy and decrease side effects. Nanodelivery of HPV preventive and therapeutic vaccines has also been investigated to increase vaccine efficacy. Overall, these developments suggest that nanoparticle-based vaccine may become the most effective way to prevent and treat cervical cancer, assisted or combined with some other nanotechnology-based therapy.

    In the current study, the fluorescence emission spectra (FES) and Stokes shift spectra (SSS) of blood and urine samples of cervical cancer patients were obtained and compared to those of normal controls. Both spectra showed that the relative intensity of biomolecules such as porphyrin, collagen, Nicotinamide adenine dinucleotide, and flavin were quite out of proportion in cervical cancer patients. The biochemical mechanism for the elevation of these fluorophores is not yet definitive; nevertheless, these biomolecules could serve as tumor markers for diagnosis, screening, and follow-up of cervical cancers. To the best of our knowledge, this is the first report on FES and SSS of blood and urine of cervical cancer patients to give a sensitivity of 80% and specificity of 78%.

    The incidence of cervical cancer has declined dramatically due to Papanicolaou smear testing. However, some minority populations continue to suffer with high incidences and/or death rates of cervical cancer, due to lack of screening. This article updates on cervical cancer screening and prevention and discusses cultural impacts on screening. Knowledge deficits disproportionately affect ethnic minority groups and contribute to cancer incidence, whereas lack of healthcare coverage and low socioeconomic status contribute to screening disparities. Although minority women have cultural beliefs and practices that influence screening, recommendation and/or education from a provider often lead to screening.

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

    Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines. Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766). Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells. Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression

    Full Text Available In the UK, women are requested to attend a cervical cancer test every 3 years as part of the NHS Cervical Screening Programme. This analysis compares the determinants of a cervical cancer screening examination with the determinants of a GP visit in the same year and investigates if cervical cancer screening participation is more likely for women who visit their GP.A recursive probit model was used to analyse the determinants of GP visits and cervical cancer screening examinations. GP visits were considered to be endogenous in the cervical cancer screening examination. The analysed sample consisted of 52,551 observations from 8,386 women of the British Household Panel Survey.The analysis showed that a higher education level and a worsening self-perceived health status increased the probability of a GP visit, whereas smoking decreased the probability of a GP visit. GP visits enhanced the uptake of a cervical cancer screening examination in the same period. The only variables which had the same positive effect on both dependent variables were higher education and living with a partner. The probability of a cervical cancer screening examination increased also with previous cervical cancer screening examinations and being in the recommended age groups. All other variables had different results for the uptake of a GP visit or a cervical cancer screening examination.Most of the determinants of visiting a GP and cervical cancer screening examination differ from each other and a GP visit enhances the uptake of a smear test.

    2006-05-01

    Full Text Available Abstract Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin or cisplatin-based chemotherapy to radiation for treatment of locally advanced cervical cancer is strongly supported by randomized studies and meta-analyses. Nevertheless, despite these significant achievements, therapeutic results are far from optimal; thus, novel therapies need to be assayed. A strategy currently being investigated is the use of newer radiosensitizers alone or in combination with platinum compounds. In the present work, we present preclinical information on known and newer cytotoxic agents as radiosensitizers on cervical cancer models, as well as the clinical information emanating from early phase trials that incorporate them to the cervical cancer management. In addition, we present the perspectives on the combined approach of radiation therapy and molecular target-based drugs with proven radiosensitizing capacity.

    Objective Cervical cancer remains a leading cause of death in many developing countries due to limited screening by Papanicolaou (Pap) smear. We sought to better understand women’s beliefs about cervical cancer and screening in Botswana, a middle income African country with high rates of cervical cancer. Methods We interviewed 289 women attending general medicine or human immunodeficiency virus (HIV) clinics, where Pap testing was available, in Gaborone, Botswana in January 2009. Results About three-quarters (72%) of respondents reported having ever had a Pap smear. HIV-positive women were more likely to have had a Pap smear than HIV-negative women (80% vs. 64%, OR=1.97, 95% CI: 1.10, 3.55). Screening was also more common among women who were older, had higher incomes, or had heard of cervical cancer. Almost all participants reported a desire to have a Pap smear. Reasons included to determine cervical health (56%), to improve overall health (33%), and to obtain early treatment (34%). About half (54%) of respondents said they did not know what causes cervical cancer, and almost none attributed the disease to HPV infection. Conclusion Study findings can inform interventions that seek to increase cervical cancer awareness and uptake of screening as it becomes more widely available. PMID:22367370

    The incidence rate of cervical cancer in Korea is still higher than in other developed countries, notwithstanding the national mass-screening program. Furthermore, a new method has been introduced in cervical cancer screening. Therefore, the committee for cervical cancer screening in Korea updated the recommendation statement established in 2002. The new version of the guideline was developed by the committee using evidence-based methods. The committee reviewed the evidence for the benefits and harms of the Papanicolaou test, liquid-based cytology, and human papillomavirus (HPV) testing, and reached conclusions after deliberation. The committee recommends screening for cervical cancer with cytology (Papanicolaou test or liquid-based cytology) every three years in women older than 20 years of age (recommendation A). The cervical cytology combined with HPV test is optionally recommended after taking into consideration individual risk or preference (recommendation C). The current evidence for primary HPV screening is insufficient to assess the benefits and harms of cervical cancer screening (recommendation I). Cervical cancer screening can be terminated at the age of 74 years if more than three consecutive negative cytology reports have been confirmed within 10 years (recommendation D). PMID:26197860

Although surgery and chemoradiotherapy can cure 80%–95% of women with early stage cancer, the recurrent and metastatic disease remains a major cause of cancer death. Many efforts have been made to design new drugs and develop gene therapies to treat cervical cancer. In recent decades, research on treatment strategies has proposed several options, including the role of HPV E6 and E7 oncogenes, which are retained and expressed in most cervical cancers and whose respective oncoproteins are critical to the induction and maintenance of the malignant phenotype. Other efforts have been focused on antitumor immunotherapy strategies. It is known that during the development of cervical cancer, a cascade of abnormal events is induced, including disruption of cellular cycle control, perturbation of antitumor immune response, alteration of gene expression, and deregulation of microRNA expression. Thus, in this review article we discuss potential targets for the treatment of cervical cancer associated with HPV infection, with special attention to immunotherapy approaches, clinical trials, siRNA molecules, and their implications as gene therapy strategies against cervical cancer development.Keywords: Cervical cancer, clinical trials, gene therapy, HPV E6 and E7 oncogenes, siRNAs

    Full Text Available Objective. To describe the incidence, mortality, time trends and prognostic factors for cervical cancer in Cali, Colombia, and to review the molecular epidemiological evidence showing that HPV is the major and necessary cause of cervical cancer and the implications of this discovery for primary and secondary prevention. Materials and methods. Incidence rates of cervical cancer during a 45-year period (1962-2007 were estimated based on the population-based cancer registry of Cali and the mortality statistics from the Municipal Health Secretariat of Cali. Prognostic factors were estimated based on relative survival. Review of the molecular epidemiological evidence linking HPV to cervical cancer was focused on the studies carried out in Cali and in other countries. Results. Incidence rates of squamous cell carcinoma (SCC declined from 120.4 per 100 000 in 1962-1966 to 25.7 in 2003-2007 while those of adenocarcinoma increased from 4.2 to 5.8. Mortality rates for cervical cancer declined from 18.5 in 1984-1988 to 7.0 per 100 000 in 2009-2011. Survival was lower in women over 65 years of age and in clinical stages 3-4. Review of the molecular epidemiological evidence showed that certain types of HPV are the central and necessary cause of cervical cancer. Conclusions. A decline in the incidence and mortality of SCC and an increase in the incidence of adenocarcinoma during a 45-year period was documented in Cali, Colombia

    Full Text Available We investigated the significance of high- mobility group box1 (HMGB1 and T-cell-mediated immunity and prognostic value in cervical cancer. HMGB1, forkhead/winged helix transcription factor p3 (Foxp3, IL-2, and IL-10 protein expression was analyzed in 100 cervical tissue samples including cervical cancer, cervical intraepithelial neoplasia (CIN, and healthy control samples using immunohistochemistry. Serum squamous cell carcinoma antigen (SCC-Ag was immunoradiometrically measured in 32 serum samples from 37 cases of squamous cervical cancer. HMGB1 and SCC-Ag were then correlated to clinicopathological characteristics. HMGB1 expression tends to increase as cervical cancer progresses and it was found to be significantly correlated to FIGO stage and lymph node metastasis. These findings suggest that HMGB1 may be a useful prognostic indicator of cervical carcinoma. In addition, there were significant positive relationships between HMGB1 and FOXP3 or IL-10 expression (both p < 0.05. In contrast, HMGB1 and IL-2 expression was negatively correlated (p < 0.05. HMGB1 expression may activate Tregs or facilitate Th2 polarization to promote immune evasion of cervical cancer. Elevated HMGB1 protein in cervical carcinoma samples was associated with a high recurrence of HPV infection in univariate analysis (p < 0.05. HMGB1 expression and levels of SCC-Ag were directly correlated in SCC (p < 0.05. Thus, HMGB1 may be a useful biomarker for patient prognosis and cervical cancer prediction and treatment.

    Full Text Available Abstract Background We introduce Approximate Entropy as a mathematical method of analysis for microarray data. Approximate entropy is applied here as a method to classify the complex gene expression patterns resultant of a clinical sample set. Since Entropy is a measure of disorder in a system, we believe that by choosing genes which display minimum entropy in normal controls and maximum entropy in the cancerous sample set we will be able to distinguish those genes which display the greatest variability in the cancerous set. Here we describe a method of utilizing Approximate Sample Entropy (ApSE analysis to identify genes of interest with the highest probability of producing an accurate, predictive, classification model from our data set. Results In the development of a diagnostic gene-expression profile for cervical intraepithelial neoplasia (CIN and squamous cell carcinoma of the cervix, we identified 208 genes which are unchanging in all normal tissue samples, yet exhibit a random pattern indicative of the genetic instability and heterogeneity of malignant cells. This may be measured in terms of the ApSE when compared to normal tissue. We have validated 10 of these genes on 10 Normal and 20 cancer and CIN3 samples. We report that the predictive value of the sample entropy calculation for these 10 genes of interest is promising (75% sensitivity, 80% specificity for prediction of cervical cancer over CIN3. Conclusion The success of the Approximate Sample Entropy approach in discerning alterations in complexity from biological system with such relatively small sample set, and extracting biologically relevant genes of interest hold great promise.

    Balancing needs for contraception and cervical cancer screening is challenging for clinicians. We assessed US obstetrician/gynecologists' practices regarding requirement of Pap testing before prescribing oral contraceptive or emergency contraceptive pills. Questionnaires structured as clinical vignettes describing women desiring contraception with different risks of cervical dysplasia were mailed to a national sample of 355 obstetrician/gynecologists. A minority (3%) of the 185 obstetrician/gynecologists who responded would refill 12 months of oral contraceptives without requiring Pap testing. However, most would provide a limited supply of oral contraceptives until Pap testing could be performed. A substantial proportion (11-16%) would refuse to prescribe emergency contraception to women who they felt required Pap testing. Younger physicians, those practicing in academic settings and those who follow American Cancer Society guidelines were more willing to prescribe contraceptives without Pap testing. Cervical cancer screening continues to limit prescription of routine and emergency contraception by many US obstetrician/gynecologists.

    Some reports have indicated that bladder cancer is induced by radiation therapy for cervical cancer. We encountered 6 cases of urothelial cancer (5 cases of bladder cancer and 1 case of ureter cancer) following radiation therapy for cervical cancer. Age at the time of diagnosis of cervical cancer ranged from 38 to 66 years, and the average was 51.2±11.0 (S.D.) years old. Age at the time of diagnosis of urothelial cancer ranged from 53 to 83 years, and the average was 67.5±10.3 years old. The interval between the diagnosis of cervical cancer and urothelial cancer ranged from 3 to 25 years, averaging 16.3 years. It is impossible to evaluate the risk of development of urothelial cancer after radiation therapy based on our data. However, it is important to make an effort to diagnose urothelial cancer at an early stage by educating patients (e.g., advising regular urine tests) after the follow-up period to cervical cancer.

    Full Text Available CONTEXT AND OBJECTIVE: Pap smears are the most common and inexpensive screening method for cervical cancer. We analyzed micronucleus prevalence in exfoliated cervical mucosa cells, to investigate associations between increased numbers of micronuclei and risk factors for cervical cancer. DESIGN AND SETTING: Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON. METHODS: Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners, age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. RESULTS: Comparisons between groups with active (7.9 ± 7.8 and passive (7.2 ± 10.6 smoking versus no smoking (3.7 ± 5.1; with/without alcoholism (7.8 ± 1.4 and 6.9 ± 10.1; with/without inflammatory cytology (10.7 ± 10.5 and 1.3 ± 1.7; and with CIN I, II and III and no CIN (respectively 4.3 ± 4.3, 10.6 ± 5.3, 22.7 ± 11.9 and 1.3 ± 1.4 found elevated micronucleus prevalence (P < 0.05. CONCLUSIONS: We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

    Full Text Available Background: Treatment effectiveness and clinical outcome of patients with cervical carcinoma FIGO stage IA1 and IA2 are analyzed in three different time period at the Department of Obstetrics and Gynecology Rijeka, Croatia. Method: Retrospective analysis of the hospital chart of all cervical cancer patients between 1991 and 2005 was conducted with five-year follow up. Results: Data on cervical cancer distribution by stage and five-year survival are presented. Separately analyzed age, histology type and treatment modalities in stage FIGO IA1 and IA2 during three consecutive five-year periods are presented. Conclusions: Conservative surgical approach – conization alone in stage IA1 of the squamous cell car- cinoma is reasonable and safe treatment option for reproductive active women. During observed periods conization became the most used surgical technique applied in almost two third of FIGO IA1 cervical cancer patients. Lymph vascular space invasion in stage IA1 lead to adjunct pelvic lymphadenectomy with unclear clinical benefit. In cervical cancer patients stage IA2 simple hysterectomy and pelvic lymphadenectomy could be accepted as a standard treatment. In these patients further studies are recommended to evaluate other less radical surgical techniques – simple and radical trachelectomy with or without pelvic lymphadenectomy. Radical hysterectomy in both stages IA1 and IA2, based on personal experience and literature data represents a surgical overtreatment and should be abandoned.

    2011-10-01

    This study aimed to evaluate reasons behind nonuptake of cervical cancer screening by women who are aware of cervical cancer screening in southeast Nigeria. Women attending gynecologic clinics of 3 health institutions in Enugu, Nigeria, were interviewed by means of a questionnaire to determine those who were aware of cervical cancer screening. The biodemographic characteristics and level of knowledge of cervical cancer screening of women who underwent a previous screen were compared with those of women who did not undergo a previous screen. Reasons for nonuptake of cervical cancer screening as well as potential reasons for undertaking cervical cancer screening were also extracted. A total of 3712 women were interviewed. Of these respondents, 2048 (55.2%) were aware of cervical cancer screening.Only 19.0% of those who were aware of cervical cancer screening underwent a previous screen. Level of knowledge of cervical cancer prevention, university education, and age had a significant impact on the uptake of cervical cancer screening. Poor health-seeking behavior and fear of violation of privacy are the major reasons for nonuptake of cervical cancer screening. Potential reasons for uptake of cervical cancer screening include development of symptoms, adequate educative information, and physician's recommendation. Women in southern Nigeria do not go for cervical cancer screening because of poor understanding of cervical cancer prevention, feeling of violation of the privacy of their genitals, and poor health-seeking behavior. There is a need to modify current policy approaches to cervical cancer prevention in Nigeria. Policies that will address the privacy violation fears and poor health-seeking behavior of the Nigerian woman as well improve the level of educative information on cervical cancer prevention need to be evolved.

    It has been shown that IAPs, in particular XIAP, survivin and c-IAP1, are overexpressed in several malignancies. In the present study we investigate the expression of c-IAP1, c-IAP2, XIAP and survivin and its isoforms in cervical cancer. We used semiquantitative RT-PCR assays to analyze 41 cancer and 6 normal tissues. The study included 8 stage I cases; 16 stage II; 17 stageIII; and a control group of 6 samples of normal cervical squamous epithelial tissue. c-IAP2 and XIAP mRNA levels were similar among the samples, cervical tumors had lower c-IAP1 mRNA levels. Unexpectedly, a clear positive association was found between low levels of XIAP and disease relapse. A log-rank test showed a significant inverse association (p = 0.02) between XIAP expression and tumor aggressiveness, as indicated by disease relapse rates. There were no statistically significant differences in the presence or expression levels of c-IAP1 and c-IAP2 among any of the clinical variables studied. Survivin and its isoforms were undetectable in normal cervical tissues, in contrast with the clear upregulation observed in cancer samples. We found no association between survivin expression and age, clinical stage, histology or menopausal state. Nevertheless, we found that adenocarcinoma tumors expressed higher levels of survivin 2B and DeltaEx3 (p = 0.001 and p = 0.04 respectively, by Kruskal-Wallis). A multivariate Cox's partial likelihood-based analysis showed that only FIGO stage was an independent predictor of outcome. There are no differences in the expression of c-IAP2 and XIAP between normal vs. cancer samples, but XIAP expression correlate in cervical cancer with relapse of this disease in the patients. Otherwise, c-IAP1 was downregulated in the cervical cancer samples. The expression of survivin was upregulated in the patients with cervical cancer. We have found that adenocarcinoma presented higher levels of survivin isoforms 2B and DeltaEx3

    Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

    Cervical Cancer is the second leading cause of cancer-related deaths in women worldwide and is associated with Human Papillomavirus (HPV) infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    INTRODUCTION: Denmark has had an organized screening programme for cervical cancer since the 1960s. In spite of this, almost 150 Danish women die from the disease each year. There are currently two different methods for preparation of cervical samples: conventional Papanicolaou smear and liquid......-based cytology. MATERIALS AND METHODS: In 2002, the Department of Pathology, Hvidovre Hospital changed over from the conventional Papanicolaou smear screening method to SurePath liquid-based cytology. This article is based on a retrospective comparison on data from the population screening programme for cervical...... cancer in the Municipality of Copenhagen. RESULTS: The number of tests with the diagnosis of "normal cells" decreased 1% after the conversion to liquid-based cytology, whilst the number of tests with "atypical cells" and "cells suspicious for malignancy" increased by 64.3% and 41.2% respectively...

    In order to spot common chromosomal imbalances in early and late lesions of cervical cancer that might be used as progression biomarkers, we made a search of literature in PubMed from 1996 to 2011. The medical subject headings employed were chromosomal alterations, loss of heterozygosis, cervical cancer, cervical tumorigenesis, chromosomal aberrations, cervical intraepithelial neoplasm and low-grade squamous intraepithelial lesion. The common chromosomal imbalances were gains in 8q24 (77.7 %), 20q13 (66.9 %), 3q26 (47.1 %), Xp22 (43.8 %), and 5p15 (60 %), principally. On the other hand, integration of the high-risk human papillomavirus genome into the host chromosome has been associated with the development of neoplasia, but the chromosomal imbalances seem to precede and promote such integration. Chromosomal imbalances in 8q24, 20q13, 3q21-26 and 5p15-Xp22, determined by fluorescent in situ hybridization assay or comparative genomic hybridization assay for early detection of the presence of high-risk human papillomavirus, are promising markers of cervical cancer progression.

    Infection, coinfection and type-specific human papillomavirus (HPV) distribution was evaluated in human immunodeficiency virus (HIV)-positive women from paired cervical and urine samples. Paired cervical and urine samples (n = 204) were taken from HIV-positive women for identifying HPV-DNA presence by using polymerase chain reaction (PCR) with three generic primer sets (GP5+/6+, MY09/11 and pU1M/2R). HPV-positive samples were typed for six high-risk HPV (HR-HPV) (HPV-16, -18, -31, -33, -45 and -58) and two low-risk (LR-HPV) (HPV-6/11) types. Agreement between paired sample results and diagnostic performance was evaluated. HPV infection prevalence was 70.6% in cervical and 63.2% in urine samples. HPV-16 was the most prevalent HPV type in both types of sample (66.7% in cervical samples and 62.0% in urine) followed by HPV-31(47.2%) in cervical samples and HPV-58 (35.7%) in urine samples. There was 55.4% coinfection (infection by more than one type of HPV) in cervical samples and 40.2% in urine samples. Abnormal Papanicolau smears were observed in 25.3% of the women, presenting significant association with HPV-DNA being identified in urine samples. There was poor agreement of cervical and urine sample results in generic and type-specific detection of HPV. Urine samples provided the best diagnosis when taking cytological findings as reference. In conclusion including urine samples could be a good strategy for ensuring adherence to screening programs aimed at reducing the impact of cervical cancer, since this sample is easy to obtain and showed good diagnostic performance.

    2002-01-01

    Background: The human papiloma virus (HPV), which is sexually transmitted, and most commonly causes genital warts, has been linked to cervical intraepithelial neoplasia and invasive carcinoma. Of ninety plus types of HPV, HPV-16 is the most prevalent in cervical cancer, followed by HPV-18, and HPV-33. As HPV's implication has not been assessed in the Middle East the main focus of this retrospective study was to determine the prevalence of HPV -16,18, and 33 in cases of cervical cancer from Iran. Material and Methods: This retrospective study covered 100 patients with uterine cervical carcinomas who were referred to two referral centers for cancer in Tehran-Iran. Pathological blocks were collected for these cases and initial review of the blocks showed poor specimens in 18 cases, which left 82 cases for the study. These samples were histologically examined to verify the presence and the type of carcinoma. The next step was in situ hybridzation for the detection of HPV common DNA. In Situ hybridization was preformed on all samples. Finally, Polymerase Chain Reaction (PCR) was preformed for the HPV types 16, 18, and 33. PCR amplification of exon 5 of the p53 gene was used as an internal control for the integrity of DNA. Takara PCR Human papilloma Detection method was used which includes primer for HPV 16, 18, and 33. Three primers were used alone, or in combination, in order to increase the sensitivity of the detection. Results: The majority of tumors were squamous cell carcinomas (87%). The rest were adenosquamous carcinoma and adenocarcinomas. None of the 82 different cervical carcinoma tissue samples were found to be positive by in situ hybridization. In the PCR samples, amplification of DNA was observed for 69 tumor specimens. In the remainning13 cases, the DNA in fixed tissue was degraded, as verified by the absence of an internal control band (p53). Out of the total 69 tumors (85.5%) with adequate DNA contained HPV band on PCR. The majority (73.9%) of HPV

    In order to increase coverage in the organized cervical screening program, self-sampling with HPV analyses has been suggested. The aim was to compare human papillomavirus (HPV) mRNA detection in vaginal and urine self-collected samples with clinician-taken cervical samples and the corresponding clinician-taken histological specimens. Self-collected vaginal, urine and clinician-taken cervical samples were analyzed from 209 women with the Aptima mRNA assay (Hologic Inc, MA, USA). Cervical cytology, colposcopy, biopsy and/or the loop electrosurgical excision procedure (LEEP) were performed in every examination. The sensitivity of the HPV mRNA test in detecting high-grade squamous intraepithelial lesions (HSIL)/adenocarcinoma in situ (AIS)/cancer cases was as follows: for the vaginal self-samples 85.5% (95% CI; 75.0-92.8), the urinary samples 44.8% (95% CI; 32.6-57.4), and for routine cytology 81.7% (95% CI; 70.7-89.9). For the clinician-taken cervical HPV samples the sensitivity of the HPV mRNA test in detecting HSIL/AIS/cancer was 100.0% (95% CI; 94.9-100.0). The specificity of the HPV mRNA was similar for the clinician-taken cervical HPV samples and the self-samples: 49.0% vs. 48.1%. The urinary HPV samples had a specificity of 61.9% and cytology had a specificity of 93.3%. The sensitivity of the Aptima HPV mRNA test in detecting HSIL/AIS/cancer from vaginal self-samples was similar to that of routine cytology. The Aptima HPV mRNA vaginal self-sampling analysis may serve as a complement in screening programs. Copyright © 2018 Elsevier B.V. All rights reserved.

    High attendance is essential to cervical cancer screening results. Attendance in the Finnish program is currently at 70%, but extensive opportunistic screening occurs beside the organized. A shift from opportunistic to organized screening is imperative to optimize the costs and impact of screening and minimize potential harms. We evaluated the effect of reminder letters (1st reminder) and self-sampling test (2nd reminder) on program attendance. The study population consisted of 31,053 screening invitees in 31 Finnish municipalities. 8,284 non-attendees after one invitation received a reminder letter and 4,536 further non-attendees were offered a self-sampling option. Socioeconomic factors related to participation were clarified by combining screening data to data from Statistics Finland. Reminder letters increased participation from 72.6% (95% CI 72.1, 73.1) to 79.2% (95% CI 78.8, 79.7) and self-sampling further to 82.2% (95% CI 81.8, 82.7). Reminder letters with scheduled appointments resulted in higher increase than open invitations (10 vs. 6%). Screening of original non-attendees increased the yield of CIN3+ lesions by 24%. Non-attendance was associated with young age, immigrant background, lower education level and having never been married. We showed that a total attendance of well over 80% can be achieved within an organized program when the invitational protocol is carefully arranged. © 2014 UICC.

    Full Text Available Background: There is an abnormal expression of nuclear receptor subfamily 2 group F member 6 (NR2F6 in human cancers such as breast cancer, colon cancer, and acute myelogenous leukemia. However, its clinical significance in cervical cancer has not been established. We explored NR2F6 expression and its clinicopathological significance in early-stage cervical cancer. Methods: NR2F6 expression in cervical cancer cell lines and cervical cancer tissues was determined by Western blotting, real-time PCR, and immunochemistry (IHC. NR2F6 expression in 189 human early-stage cervical cancer tissue samples was evaluated using IHC. The relevance between NR2F6 expression and early-stage cervical cancer prognosis and clinicopathological features was determined. Results: There was marked NR2F6 mRNA and protein overexpression in the cervical cancer cells and clinical tissues compared with an immortalized squamous cell line and adjacent noncancerous cervical tissues, respectively. In the 189 cervical cancer samples, NR2F6 expression was positively related to International Federation of Gynecology and Obstetrics (FIGO stage (p = 0.006, squamous cell carcinoma antigen (p = 0.006, vital status (p < 0.001, tumor recurrence (p = 0.001, chemotherapy (p = 0.039, and lymph node metastasis (p < 0.001. Overall and disease-free survival was shorter in patients with early-stage cervical cancer and higher NR2F6 levels than in patients with lower levels of NR2F6. Univariate and multivariate analysis determined that NR2F6 was an independent prognostic factor of survival in early-stage cervical cancer. Conclusions: Taken together, our findings suggest that high NR2F6 expression predicts pelvic lymph node metastasis, tumor recurrence and poor prognosis in early-stage cervical cancer. NR2F6 might be a novel prognostic biomarker and potential therapeutic target of cervical cancer.

    Full Text Available ABSTRACT: Introduction: Human papillomavirus (HPV is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r HPV Genotyping test (Roche. Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%. Of these samples, 604 (38.20% were positive for a single HPV genotype, while another 85 (5.37% samples were positive for multiple HPV types. Genotype 16 (5.50% resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55% and HPV 11 (3.80% occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

    Previous studies indicate that cervical cancer is the second most frequent cancer and most common cause of cancer mortality among women in Fiji. There is little published data on the epidemiology of cervical cancer in Pacific countries. To determine the incidence 2003-2009 of, and mortality 2003-2008 from, cervical cancer by ethnicity and period in Fiji, identify evidence of secular change and relate these data to other Pacific countries, Australia and New Zealand. Counts of incident cervical cancer cases (2003-2009) and unit record mortality data (2003-2008) from the Fiji Ministry of Health were used to calculate age-standardised (to the WHO World Population) cervical cancer incidence and mortality rates, and cervical or uterine cancer mortality rates, by ethnicity, with 95% confidence intervals. On the basis of comparison of cervical cancer mortality with cervical or uterine cancer mortality in Fiji with similar populations, misclassification of cervical cancer deaths is unlikely. There is no evidence of secular change in cervical cancer incidence and mortality rates for the study period. For women of all ages and ethnicities, the age-standardised incidence rate of cervical cancer (2003-2009) was 27.6 per 100,000 (95% CI 25.4-29.8) and the age-standardised mortality rate (2003-2008) was 23.9 per 100,000 (95% CI 21.5-26.4). The mortality/incidence ratio was 87%. Fijians had statistically significant higher age-standardised incidence and mortality rates than Indians. Fiji has one of the highest estimated rates of cervical cancer incidence and mortality in the Pacific region. Cervical cancer screening in Fiji needs to be expanded and strengthened. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Haitian immigrant women, the largest growing Black ethnic group in Miami, experience the highest rates of cervical cancer and account for one of the largest populations diagnosed with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in South Florida. Using community-based participatory research methods, we conducted a pilot study to examine human papilloma virus (HPV)/cervical cancer knowledge and identify intervention preferences among HIV positive Haitian women. Community health workers conducted three focus groups with 21 HIV-positive Haitian women. All sessions were conducted in Haitian Kreyol, digitally recorded, and subsequently interpreted and transcribed into English. The first focus group assessed HPV/cervical cancer knowledge, the second session explored HPV/cervical cancer considerations specific to HIV-positive women, and the third focus group discussed HPV/cervical cancer screening and intervention preferences. Data analysis was guided by a grounded theory approach. Our sample had limited HPV/cervical cancer knowledge. Misconceptions about screening, transmission, and treatment were common. Participants felt that stigma by providers impacted negatively the care they received and that stigma by the community diminished social support. Strong support for culturally tailored interventions to improve HPV/cervical cancer knowledge was expressed. Although no participants had participated in research previously, all were willing to participate in future trials. There is critical need for culturally relevant interventions to improve HPV/cervical cancer knowledge among HIV-positive Haitian women. Copyright © 2015 Jacobs Institute of Women's Health.

    The oncogenic human papilloma viruses (HPVs) are associated with precancerous cervical lesions and development of cervical cancer. The DNA methylation signatures of the host genome in normal, precancerous and cervical cancer tissue may indicate tissue-specific perturbation in carcinogenesis. The aim of this study was to identify new candidate genes that are differentially methylated in squamous cell carcinoma compared with DNA samples from cervical intraepithelial neoplasia grade 3 (CIN3) and normal cervical scrapes. The Illumina Infinium HumanMethylation450 BeadChip method identifies genome-wide DNA methylation changes in CpG islands, CpG shores and shelves. Our findings showed an extensive differential methylation signature in cervical cancer compared with the CIN3 or normal cervical tissues. The identified candidate biomarker genes for cervical cancer represent several types of mechanisms in the cellular machinery that are epigenetically deregulated by hypermethylation, such as membrane receptors, intracellular signaling and gene transcription. The results also confirm extensive hypomethylation of genes in the immune system in cancer tissues. These insights into the functional role of DNA methylome alterations in cervical cancer could be clinically applicable in diagnostics and prognostics, and may guide the development of new epigenetic therapies.

In the absence of large, prospective clinical trials investigating the optimal management strategies for cervical dysplasia in pregnant women, consensus guidelines established by the American Society for Colposcopy and Cervical Pathology is available with considerations to this special patient population. Modalities for evaluation and management algorithms are reviewed and summarized from largely case series of pregnant women with cervical dysplasia and cervical cancer.

    It is widely accepted that cervical screening has significantly reduced the incidence of cervical cancer worldwide. The primary screening test for cervical cancer is the Papanicolaou (Pap) test, which has extremely variable specificity and sensitivity. There is an unmet clinical need for methods to aid clinicians in the early detection of cervical precancer. Raman spectroscopy is a label-free objective method that can provide a biochemical fingerprint of a given sample. Compared with studies on infrared spectroscopy, relatively few Raman spectroscopy studies have been carried out to date on cervical cytology. The aim of this study was to define the Raman spectral signatures of cervical exfoliated cells present in liquid-based cytology Pap test specimens and to compare the signature of high-grade dysplastic cells to each of the normal cell types. Raman spectra were recorded from single exfoliated cells and subjected to multivariate statistical analysis. The study demonstrated that Raman spectroscopy can identify biochemical signatures associated with the most common cell types seen in liquid-based cytology samples; superficial, intermediate, and parabasal cells. In addition, biochemical changes associated with high-grade dysplasia could be identified suggesting that Raman spectroscopy could be used to aid current cervical screening tests.

    Cervical cancer remains one of the most significant problem in oncogynecology. It tends towards treatment approaches that provide termination of pathological processes along with preservation of the patient's life quality. There is a need in earlier and more accurate diagnosis of pathological states, objective assessment of physiological processes, and adequate monitoring of the course of treatment. In our previous publications we have reported unique capabilities of the Optical Coherence Tomography (OCT) to image in vivo the mucosa structure of the cervix and to monitor various physiological and pathological alterations. In this report, we present results of OCT application to diagnose different stages of cervical cancer and to control its treatment at early stages. We have performed OCT-colposcopy in 11 female patients with cervical cancer to derive OCT criteria of this disease, to provide exact demarcation of a pathological area, and to determine a real size of a tumor. We have found that, in general, borders of a tumor, defined visually and detected with OCT by violation of the basement membrane in exocervix, do not coincide. The mismatch depends on a stage of cancer and can be as much as several millimeters. This information is especially important for evaluation of linear dimension of tumors with 3 - 5 mm invasion and also for differential diagnosis between the T1 and T2 stages with cancer extension onto vagina.

    To examine the expressions of HLA class I antigen and CD8 in various cervical diseases and investigate their association with cervical cancer. The expressions of HLA class I antigen and CD8 in cervical tissues sampled from patients with cervical cancer, cervical intraepithelial neoplasia (CIN), and chronic cervicitis were detected using SP immunohistochemistry. The association of the expressions of HLA class I antigen and CD8 with the clinicopathologic indices of the patients was analyzed. The positive expression rates of HLA class I antigen in cervical cancer, CIN, and chronic cervicitis were 22.6%, 100.0%, and 100.0%, and the positive expression rates of CD8 were 22.6%, 95.5%, and 100.0%, respectively. The positive rates of HLA class I antigen and CD8 were significantly lower in patients with cervical cancer (Pcancer had significantly higher positive rates of HLA class I antigen and CD8 than those with stage II cervical cancer (46.7% vs 0.0%, 46.7% vs 0.0%, both PHLA class I antigen and CD8 decreased with the progression of the clinicopathological stages, and may even become undetectable. The expressions of HLA class I antigen and CD8 were not related to the differentiation degree of the tumor or lymph node metastasis (P>0.05). A positive correlation was found between HLA class I antigen expression and CD8 expression. The expressions of HLA class I antigen and CD8 are down-regulated or deleted in CIN and cervical cancer, and they may play important roles in the development and progression of CIN and cervical cancer.

    To investigate the infection status and predominant genotype distribution of human papillomavirus (HPV) infection among Chinese patients with mucopurulent cervicitis (MPC) or cervical cancer (CC) in Hangzhou. Initially, 217 cases of healthy cervix controls (n=50), acute MPC (n=89), and CC (n=78) were included; samples were collected between January 1, 2010, and January 30, 2013. Cervical specimens were screened for HPV using a nested polymerase chain reaction assay and DNA sequencing. Overall prevalence of HPV infection was 16.7% in the control group, 51.9% in the MPC group, and 84.4% in the CC group. The predominant genotype detected in all 3 groups was the oncogenic variant HPV 16 (55.8%, 17.3%, and 6.3% in the CC, MPC and control specimens, respectively), HPV58 was the second most predominant HPV type in CC (9.1%), MPC (8.6%), and control group (4.2%). Most or all of the genotypes were oncogenic in the three groups. Infection with HPV was found to be prevalent among Chinese women with MPC or CC and oncogenic variants were in the majority. Therefore, peoples who suffered MPC with HPV DNA positive should be regularly followed-up, for prevention and early treatment of cervical cancer.

    Full Text Available Background and Objectives: Cervical cancer is a leading cause of cancer mortality among women in India. Hence, the objectives of this study were to find out the perception of women towards cervical cancer and assess their health-seeking behavior for screening. Methodology: A cross-sectional study was conducted from November to December 2009 among married women above 15 years of age by systematic random sampling of households in Field Ganj, Ludhiana, India. Information was gathered by a questionnaire assessing the knowledge, attitude, and practices regarding cervical cancer. Results: Of the 304 women interviewed, 28.9% (88 had heard of cervical cancer and 12.2% (37 knew it could be preventable. Only 4.3% (13 of the women had heard about Pap smear. Interpretation and Conclusions: Inadequate knowledge about cervical cancer and Pap smear is the greatest obstacle to effective screening. Identifying individual and community-level barriers is important in increasing cervical cancer screening.

    Full Text Available Abstract Background Women with cervical cancer now have relatively good 5-year survival rates. Better survival rates have driven the paradigm in cancer care from a medical illness model to a wellness model, which is concerned with the quality of women's lives as well as the length of survival. Thus, the assessment of quality of life among cervical cancer survivors is increasingly paramount for healthcare professionals. The purposes of this review were to describe existing validated quality of life instruments used in cervical cancer survivors, and to reveal the implications of quality of life measurement for Chinese cervical cancer survivors. Methods A literature search of five electronic databases was conducted using the terms cervical/cervix cancer, quality of life, survivors, survivorship, measurement, and instruments. Articles published in either English or Chinese from January 2000 to June 2009 were searched. Only those adopting an established quality of life instrument for use in cervical cancer survivors were included. Results A total of 11 validated multidimensional quality of life instruments were identified from 41 articles. These instruments could be classified into four categories: generic, cancer-specific, cancer site-specific and cancer survivor-specific instruments. With internal consistency varying from 0.68-0.99, the test-retest reliability ranged from 0.60-0.95 based on the test of the Pearson coefficient. One or more types of validity supported the construct validity. Although all these instruments met the minimum requirements of reliability and validity, the original versions of these instruments were mainly in English. Conclusion Selection of an instrument should consider the purpose of investigation, take its psychometric properties into account, and consider the instrument's origin and comprehensiveness. As quality of life can be affected by culture, studies assessing the quality of life of cervical cancer survivors in

    We already know what causes cervical cancer, how to prevent it, and how to treat it, even in resource-constrained settings. Inequitable access to human papillomavirus vaccine for girls and screening and precancer treatment for women in low- and middle-income countries is unacceptable on ethical, social, and financial grounds. The burden of cervical cancer falls on the poor and extends beyond the narrow bounds of the family, affecting national economic development and community life, as family resources are drained and poverty tightens its grip. Proven solutions are available and the priorities for the next few years are clear, as shown by the papers in this Supplement. Sustained political commitment and strategic investments in cervical cancer prevention can not only save millions of lives over the next 10 years, but can also pave the way for the broader fight against all cancers. © 2017 The Authors.

    Full Text Available Experimental, clinical, and epidemiological evidence strongly suggests that genital Human Papillomaviruses (HPVs are predominantly sexually transmitted. Epidemiological studies in virginal and HPV-negative women clearly indicate that sexual intercourse is virtually a necessary step for acquiring HPV. As with any other sexually transmitted disease (STD men are implicated in the epidemiological chain of the infection. Penile HPVs are predominantly acquired through sexual contacts. Sexual contacts with women who are prostitutes play an important role in HPV transmission and in some populations sex workers may become an important reservoir of high-risk HPVs. Acting both as "carriers" and "vectors" of oncogenic HPVs male partners may markedly contribute to the risk of developing cervical cancer in their female partners. Thus, in the absence of screening programs, a woman's risk of cervical cancer may depend less on her own sexual behavior than on that of her husband or other male partners. Although more rarely than women, men may also become the "victims" of their own HPV infections as a fraction of infected men are at an increased risk of developing penile and anal cancers. Male circumcision status has been shown to reduce the risk not only of acquiring and transmitting genital HPVs but also of cervical cancer in their female partners. More research is needed to better understand the natural history and epidemiology of HPV infections in men.

    Cervical cancer is the second most frequent cancer among women in Busan. The Pap smear test could have a significant effect on detecting cervical cancer, and enhancing their rate of use is an important strategy for reducing the incidence and mortality of cervical cancer. This study aimed to evaluate the factors associated with the past use of the Pap smear test in Korean women. A population-based survey was carried out in Busan between November 1999 and March 2000. 1, 673 participants were randomly selected from 2, 684 women in Busan, using a 2-stage cluster sampling method, and interviewed in their homes. Their socio-demographic characteristics, smoking, drinking, familial cancer history, Pap smear screening history, reproductive and menstrual factors, sexual habits and use of contraceptive methods data were collected by a trained interviewer using a questionnaire. The use of the screening test was defined by a self-report from the participants on how many times they had had a Pap smear test in their lifetime, and when they had received their latest examination. Of the 1, 673 respondents (62.3% response rate), 57.6% had had a Pap smear test during her life (mean number, 2.3). Among the health examination participants (1, 064), 961 (90.3%) reported having sexual experience and 70.9% of these had had a Pap smear test. In a multiple logistic regression analysis, statistically significant relationships were observed for age groups and the Pap smear test rate (odds ratio, OR for 35-44 years=2.45; OR for 45-54 years=3.41; OR for 55 years=2.60; reference, under 34 years). The married or cohabiting women were more likely to have used the Pap smear test than those separated or widowed (OR=1.73). Among the reproductive behavioral measures, the number of births (OR for 3 births=4.22; OR for 2 births=3.95; OR for 1 births=3.38; reference, 0 births) and husband's extra-marital affairs (OR=1.50) were associated with the rates of use of Pap smear tests. It appears that the most

    The primary objective of this study was to assess the knowledge of medical students and determine variation between different cultural groups. A secondary aim was to find out the willingness to pay for cervical cancer vaccination and the relationships between knowledge and attitudes towards Human Papillomavirus vaccination. A cross-sectional survey was conducted in a private medical university between June 2014 and November 2014 using a convenient sampling method. A total of 305 respondents were recruited and interviewed with standard questionnaires for assessment of knowledge, attitudes and practice towards human papilloma virus and their willingness to pay for HPV vaccination. Knowledge regarding human papilloma virus, human papilloma virus vaccination, cervical cancer screening and cervical cancer risk factors was good. Across the sample, a majority (90%) of the pupils demonstrated a high degree of knowledge about cervical cancer and its vaccination. There were no significant differences between ethnicity and the participants' overall knowledge of HPV infection, Pap smear and cervical cancer vaccination. Some 88% of participants answered that HPV vaccine can prevent cervical cancer, while 81.5% of medical students said they would recommend HPV vaccination to the public although fewer expressed an intention to receive vaccination for themselves.

    The incidence of cervical cancer is high among Southeast Asian American women, but their participation in preventive cervical cancer screening is alarmingly low. This paper reviews the literature on factors associated with participation in cervical cancer screening among women of Vietnamese, Cambodian and Hmong descent in the United States. These factors include acculturation, age, marital status, knowledge about cervical cancer, apprehension about cervical cancer screening, financial concerns, access to health care, and physician characteristics and recommendation. Suggestions for future research include the need to investigate the role of physicians treating Southeast Asian American women, the need for more extensive up-to-date studies on the current generation of young Southeast Asian American women, and the use of more advanced assessments of acculturation. Overall, much more work is needed in order to deepen our understanding of the various ways to improve the rate of cervical cancer screening among Southeast Asian American women.

    Conventional analysis of a cervical histology image, such a pap smear or a biopsy sample, is performed by an expert pathologist manually. This involves inspecting the sample for cellular level abnormalities and determining the spread of the abnormalities. Cancer is graded based on the spread of the abnormal cells. This is a tedious, subjective and time-consuming process with considerable variations in diagnosis between the experts. This paper presents a computer aided decision support system (CADSS) tool to help the pathologists in their examination of the cervical cancer biopsies. The main aim of the proposed CADSS system is to identify abnormalities and quantify cancer grading in a systematic and repeatable manner. The paper proposes three different methods which presents and compares the results using 475 images of cervical biopsies which include normal, three stages of pre cancer, and malignant cases. This paper will explore various components of an effective CADSS; image acquisition, pre-processing, segmentation, feature extraction, classification, grading and disease identification. Cervical histological images are captured using a digital microscope. The images are captured in sufficient resolution to retain enough information for effective classification. Histology images of cervical biopsies consist of three major sections; background, stroma and squamous epithelium. Most diagnostic information are contained within the epithelium region. This paper will present two levels of segmentations; global (macro) and local (micro). At the global level the squamous epithelium is separated from the background and stroma. At the local or cellular level, the nuclei and cytoplasm are segmented for further analysis. Image features that influence the pathologists' decision during the analysis and classification of a cervical biopsy are the nuclei's shape and spread; the ratio of the areas of nuclei and cytoplasm as well as the texture and spread of the abnormalities

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

    Full Text Available Mariah Ngutu, Isaac K Nyamongo Institute of Anthropology, Gender and African Studies (IAGAS, University of Nairobi, Nairobi, Kenya Abstract: Cervical cancer is the most frequent cancer among women aged between 15 years and 44 years in Kenya, resulting in an estimated 4,802 women being diagnosed with cervical cancer and 2,451 dying from the disease annually. It is often detected at its advanced invasive stages, resulting in a protracted illness upon diagnosis. This qualitative study looked at the illness trajectories of women living with cervical cancer enrolled for follow-up care at Kenyatta National Hospital cancer treatment center and the Nairobi Hospice, both in Nairobi county, Kenya. Using the qualitative phenomenological approach, data were collected through 18 in-depth interviews with women living with cervical cancer between April and July 2011. In-depth interviews with their caregivers, key informant interviews with health care workers, and participant observation field notes were used to provide additional qualitative data. These data were analyzed based on grounded theory’s inductive approach. Two key themes on which the data analysis was then anchored were identified, namely, psychosocial challenges of cervical cancer and structural barriers to quality health care. Findings indicated a prolonged illness trajectory with psychosocial challenges, fueled by structural barriers that women were faced with after a cervical cancer diagnosis. To address issues relevant to the increasing numbers of women with cervical cancer, research studies need to include larger samples of these women. Also important are studies that allow in-depth understanding of the experiences of women living with cervical cancer. Keywords: qualitative, illness trajectories, women, cervical cancer

    Patients with advanced or recurrent cervical cancer have poor prognosis, and their 1-year survival is only 10%–20%. Chemotherapy is considered as the standard treatment for patients with advanced or recurrent cervical cancer, and cisplatin appears to treat the disease effectively. However, resistance to cisplatin may develop, thus substantially compromising the efficacy of cisplatin to treat advanced or recurrent cervical cancer. In this article, we systematically review the recent literature and summarize the recent advances in our understanding of the molecular mechanisms underlying cisplatin resistance in cervical cancer.

    Purpose: The aim of this study was to evaluate efficacy of gynecologic examination under general anesthesia with cervical biopsies after (chemo) radiation for cervical cancer to identify patients with residual disease who may benefit from salvage surgery. Methods and Materials: In a retrospective cohort study data of all cervical cancer patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IB1 to IVA treated with (chemo) radiation between 1994 and 2001 were analyzed. Patients underwent gynecologic examination under anesthesia 8 to 10 weeks after completion of treatment. Cervical biopsy samples were taken from patients judged to be operable. In case of residual cancer, salvage surgery was performed. Results: Between 1994 and 2001, 169 consecutive cervical cancer patients received primary (chemo) radiation, of whom 4 were lost to follow-up. Median age was 56 years (interquartile range [IQR], 44-71) and median follow-up was 3.5 years (IQR, 1.5-5.9). In each of 111 patients a biopsy sample was taken, of which 90 (81%) showed no residual tumor. Vital tumor cells were found in 21 of 111 patients (19%). Salvage surgery was performed in 13 of 21 (62%) patients; of these patients, 5 (38%) achieved long-term, complete remission after salvage surgery (median follow-up, 5.2 years; range, 3.9-8.8 years). All patients with residual disease who did not undergo operation (8/21) died of progressive disease. Locoregional control was more often obtained in patients who underwent operation (7 of 13) than in patients who were not selected for salvage surgery (0 of 8 patients) (p < 0.05). Conclusions: Gynecologic examination under anesthesia 8 to 10 weeks after (chemo) radiation with cervical biopsies allows identification of those cervical cancer patients who have residual local disease, of whom a small but significant proportion may be salvaged by surgery

    Full Text Available OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women’s health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2. Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5. A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease. Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.

    Full Text Available BACKGROUND: While HPV infection is the main cause of cervical cancer, genetic susceptibility to HPV infection is not well understood. Tumor necrosis factor alpha (TNF-alpha, involved in the defense against HPV infection, plays an important role in cervical cancer progression and regression. The aim of this study was to investigate the relationship between the TNF-alpha rs1800629 polymorphism and risk of HPV infection or cervical cancer. METHODS: Three groups were involved in this study of Chinese women. Group 1 consisted of 285 high risk HPV positive cervical cancer patients, Group 2, 225 high risk HPV positive patients without cervical cancer, and Group 3, 318 HPV negative women with no cervical cancer. Blood samples were obtained from all patients and genotyped by PCR-RLFP. Fifty randomly selected samples were further sequenced. RESULTS: The allele and genotype distributions of the TNF-alpha rs1800629 polymorphism were not significantly different between each of the groups (P>0.05. There are no significant relationship between rs1800629 polymorphism and high risk HPV infection (OR = 0.649, 95% CI: 0.253-1.670, P = 0.371, cervical cancer (OR = 0.993, 95% CI: 0.376-2.618, P = 0.988, or cervical cancer with HPV infection (OR = 0.663, 95% CI: 0.250-1.758, P = 0.409. CONCLUSIONS: We demonstrated that there is no association between TNF rs1800629 polymorphism and the HPV infection, or cervical cancer with HPV infection.

    Full Text Available ABSTRACT Objective To assess cervical cancer prevalence and associated mortality in Grenada, West Indies during 2000–2010. Methods Records of visits to hospital and clinical facilities were obtained from the histopathology laboratory of the Grenada General Hospital. Records were de-identified and electronically compiled. Cervical cancer prevalence was assessed via cross-sectional analysis of this secondary data. Of a total 12 012 records, 2 527 were selected for analysis using sampling without replacement. Cases were matched to corresponding patient data from death registries, where possible, and used to calculate associated mortality rates. Results The observed prevalence of cervical cancer was 52.4 per 100 000 women (ages 15 and above. The highest rates of cervical cancer occurred in the 35–44 age group, with the second highest among 45–64-year-olds. A total of 65 deaths were attributable to cervical cancer during 2000–2010, more than 50% of which were among women > 65 years old. The observed mortality rate was 16.7 per 100 000, almost twice the rate estimated by WHO for the region. Conclusions This study demonstrates the need for a comprehensive cervical cancer-screening program in Grenada. Results should contribute to informing future studies on how to appropriately generate and execute public health policy for education, screening, prevention, and control of cervical cancer in Grenada.

    Full Text Available Abstract Background Smac/Diablo is a recently identified protein that is released from mitochondria after apoptotic stimuli. It binds IAPs, allowing caspase activation and cell death. In view of its activity it might participate in carcinogenesis. In the present study, we analyzed Smac expression in a panel of cervical cancer patients. Methods We performed semi quantitative RT-PCR on 41 cervical tumor and 6 normal tissue samples. The study included 8 stage I cases; 16 stage II; 17 stage III; and a control group of 6 samples of normal cervical squamous epithelial tissue. Results Smac mRNA expression was below the detection limit in the normal cervical tissue samples. In contrast, 13 (31.7% of the 41 cervical cancer biopsies showed detectable levels of this transcript. The samples expressing Smac were distributed equally among the stages (5 in stage I, 4 in stage II and 4 in stage III with similar expression levels. We found no correlation between the presence of Smac mRNA and histology, menopause, WHO stage or disease status. Conclusions Smac is expressed de novo in a subset of cervical cancer patients, reflecting a possible heterogeneity in the pathways leading to cervical cancer. There was no correlation with any clinical variable.

  11. Human Papillomavirus Testing in the Prevention of Cervical Cancer

    Strong evidence now supports the adoption of cervical cancer prevention strategies that explicitly focus on persistent infection with the causal agent, human papillomavirus (HPV). To inform an evidence-based transition to a new public health approach for cervical cancer screening, we summarize the natural history and cervical carcinogenicity of HPV and discuss the promise and uncertainties of currently available screening methods. New HPV infections acquired at any age are virtually always benign, but persistent infections with one of approximately 12 carcinogenic HPV types explain virtually all cases of cervical cancer. In the absence of an overtly persistent HPV infection, the risk of cervical cancer is extremely low. Thus, HPV test results predict the risk of cervical cancer and its precursors (cervical intraepithelial neoplasia grade 3) better and longer than cytological or colposcopic abnormalities, which are signs of HPV infection. The logical and inevitable move to HPV-based cervical cancer prevention strategies will require longer screening intervals that will disrupt current gynecologic and cytology laboratory practices built on frequent screening. A major challenge will be implementing programs that do not overtreat HPV-positive women who do not have obvious long-term persistence of HPV or treatable lesions at the time of initial evaluation. The greatest potential for reduction in cervical cancer rates from HPV screening is in low-resource regions that can implement infrequent rounds of low-cost HPV testing and treatment. PMID:21282563

    Cervical cancer is the third most common cancer among women worldwide. Several factors lead to cervical cancer, among which human papilloma virus (HPV) infection has a prominent role. Methylenetetrahydrofolate reductase (MTHFR) is crucial in folate metabolic pathway and plays an important role in DNA synthesis and DNA methylation. MTHFR gene polymorphisms, including C677T and A1298C, lead to reduced enzyme activity. This case-control study aims to illustrate the association between MTHFR gene polymorphisms and the risk of cervical cancer. This study was conducted on 196 samples, which included 96 cervical biopsy samples compared to 100 Pap smear samples of normal healthy women without HPV infection. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for the MTHFR polymorphism detection, followed by fluorescent amplification-based specific hybridization PCR method to detect HPV16 and HPV18. The results show that the MTHFR 677TT genotype plays a protective role in cervical cancer (P=0.0030) (OR=0.21, 95% confidence interval [CI]: 0.07-0.59). Furthermore, there was a strong significant association between MTHFR 1298CC genotype and the risk of cervical cancer (OR=10.69; 95% CI: 4.28-26.71, P=0.0001). It can be concluded that A1298C polymorphism is a genetic risk factor for cervical cancer in the assessed Iranian population group. It seems that MTHFR 1298CC genotype is more susceptible to HPV 16 infection. Combination analysis of MTHFR C677T and A1298C polymorphisms revealed that combined MTHFR 677CC and 1298CC are strongly associated with a risk of cervical cancer. Copyright © 2016 Elsevier B.V.

    The aim of this study was to estimate the effect of cervical screening in the prevention of invasive cervical cancer among age groups, using a population-based case-control study in the province of Ontario, Canada. Exposure was defined as cervical cytology history greater than 3 months before the diagnosis date of cervical cancer (index date). Cases were women who were diagnosed with cervical cancer between January 1, 1998, and December 31, 2008. Controls were women without a diagnosis of cervical cancer on, or before, December 31, 2008. Two controls were matched to each case on year of birth and income quintile, as of the index date. Conditional logistic regression was used to estimate the odds ratio for having been screened among those with cervical cancer. Cervical cancer screening performed between 3 and 36 months before the index date was protective against invasive cervical cancer in women aged 40 through 69 years. In women younger than 40 years, cervical cancer screening performed 3 to 36 months before the index date was not protective. Cervical screening is associated with a reduced risk for invasive cervical cancer among women older than 40 years. Cervical cancer resources should be focused on maximizing the risk reduction.

    There is currently limited information about human papillomavirus (HPV) genotype distribution in women in the South Pacific region. This study's objective was to determine HPV genotypes present in cervical cancer (CC) and precancers (cervical intraepithelial lesion (CIN) 3) in Fiji. Cross-sectional analysis evaluated archival CC and CIN3 biopsy samples from 296 women of Melanesian Fijian ethnicity (n=182, 61.5%) and Indo-Fijian ethnicity (n=114, 38.5%). HPV genotypes were evaluated using the INNO-LiPA assay in archival samples from CC (n=174) and CIN3 (n=122) among women in Fiji over a 5-year period from 2003 to 2007. Overall, 99% of the specimens tested were HPV DNA-positive for high-risk genotypes, with detection rates of 100%, 97.4% and 100% in CIN3, squamous cell carcinoma (SCC) and adenosquamous carcinoma biopsies, respectively. Genotypes 16 and 18 were the most common (77%), followed by HPV 31 (4.3%). Genotype HPV 16 was the most common identified (59%) in CIN3 specimens, followed by HPV 31 (9%) and HPV 52 (6.6%). Multiple genotypes were detected in 12.5-33.3% of specimens, depending on the pathology. These results indicated that the two most prevalent CC-associated HPV genotypes in Fiji parallel those described in other regions worldwide, with genotype variations thereafter. These data suggest that the currently available bivalent and quadrivalent HPV vaccines could potentially reduce cervical cancers in Fiji by over 80% and reduce precancers by at least 60%.

    Circulating HPV DNA has been previously described in women with advanced stages of cervical cancer and has been suggested to be a prognostic marker of disease recurrences and metastases. Only a few studies have reported the presence of HPV DNA in bloodstream of patients with low grade or precancerous cervical lesions. This study aimed to define if HPV DNA could be detected in plasma samples of 120 women referred for a recent history of cervical dysplasia who presented with lesions ranging from High Squamous Intraepithelial Lesion (H-SIL) to regressed normal cytology. HPV DNA detection was carried out in both plasma and cervical samples using type-specific real-time quantitative PCR assays identifying oncogenic HPV 16, 18, 31, 33, 45, 51 and 52. Overall, 34.2% (41/120) of plasma samples were shown to be positive for HPV DNA detection; HPV 45 (46.3%), HPV-51 (29.6%), and HPV 16 (18.5%) were the most frequently identified genotypes. The rate of HPV detection in paired cervical and plasma samples increased with advancing disease stage, ranging from 15.4% in women with regressed lesions to 38.9% in women with HSIL; HPV 16 resulted the most common genotype identified in women found to be HPV DNA positive in both cervical and plasma samples. Moreover, HPV 16 showed the highest median viral load value in both cervical and plasma samples, with 48,313 copies/104 cells and 1,099 copies/ml, respectively. Results obtained in this study confirm that HPV DNA can be detected and quantified in plasma samples of women with asymptomatic cervical infection. Further knowledge on HPV dissemination through the blood stream of women with cervical lesions would be very important in better understanding the natural history of HPV infection as well as its potential role in other distant tumors.

This study aimed to define if HPV DNA could be detected in plasma samples of 120 women referred for a recent history of cervical dysplasia who presented with lesions ranging from High Squamous Intraepithelial Lesion (H-SIL to regressed normal cytology. HPV DNA detection was carried out in both plasma and cervical samples using type-specific real-time quantitative PCR assays identifying oncogenic HPV 16, 18, 31, 33, 45, 51 and 52. Overall, 34.2% (41/120 of plasma samples were shown to be positive for HPV DNA detection; HPV 45 (46.3%, HPV-51 (29.6%, and HPV 16 (18.5% were the most frequently identified genotypes. The rate of HPV detection in paired cervical and plasma samples increased with advancing disease stage, ranging from 15.4% in women with regressed lesions to 38.9% in women with HSIL; HPV 16 resulted the most common genotype identified in women found to be HPV DNA positive in both cervical and plasma samples. Moreover, HPV 16 showed the highest median viral load value in both cervical and plasma samples, with 48,313 copies/104 cells and 1,099 copies/ml, respectively. Results obtained in this study confirm that HPV DNA can be detected and quantified in plasma samples of women with asymptomatic cervical infection. Further knowledge on HPV dissemination through the blood stream of women with cervical lesions would be very important in better understanding the natural history of HPV infection as well as its potential role in other distant tumors.

    Incidence of second primary cancers was evaluated in 7,127 women with invasive cancer of the cervix uteri, diagnosed between 1935 and 1978, and followed up to 38 years (average, 8.9 yr) in Connecticut. Among 5,997 women treated with radiation, 449 developed second primary cancers compared with 313 expected (relative risk . 1.4) on the basis of rates from the Connecticut Tumor Registry. Excess incidence was noticeable 15 years or more after radiotherapy and attributed mostly to cancers of sites in or near the radiation field, especially the bladder, kidneys, rectum, corpus uteri, and ovaries. No excess was found for these sites among the 1,130 nonirradiated women. The ratio of observed to expected cancers for these sites did not vary appreciably by age at irradiation. The data suggested that high-dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but, apparently, not leukemia, Hodgkin's disease, breast cancer, or colon cancer

    Arsenic in drinking water is causally linked with cancer of the skin, lung, and urinary bladder, but there is very little data on a possible role for arsenic in the etiology of cervical cancer, a disease in which human papilloma virus is held to be a necessary but not sufficient cause. All histopathology results from cervical specimens from the National Institute of Cancer Research and Hospital (NICRH), Dhaka (1997-2015), and the Anowara Medical Services (2003-2015), both serving the whole of Bangladesh, were classified by cell type. Arsenic concentrations in well water in the thana of residence were estimated from systematic sampling carried out by the British Geological Survey. In a case-referent analysis arsenic estimates for cases of cervical cancer were compared with those found to have benign lesions. In this study, 3464 NICRH (CH) cervical specimens and 30,050 community medical service (CMS) specimens were available: 3329 (CH) and 899 (CMS) were recorded as malignant. Most were squamous cell carcinoma, of which 4.9% were poorly differentiated. Overall, there was no increase in cervical cancer with increasing arsenic concentration. Among those with squamous cell histology, a strong dose response was seen for poorly differentiated cancer with increasing arsenic exposure. The odds ratio increased monotonically, compared with exposure 200 μg/L (p 50 μg/L of arsenic, the evidence that arsenic is implicated in cancer grade suggests a need for further investigation and the introduction of cervical screening in high arsenic areas.

    Full Text Available Cervical cancer affects millions of Americans, but the rate for cervical cancer in the Mexican American is approximately twice that for non-Mexican Americans. The etiologies of cervical cancer are still not fully understood. A number of somatic mutations, including several copy number alterations (CNAs, have been identified in the pathogenesis of cervical carcinomas in non-Mexican Americans. Thus, the purpose of this study was to investigate CNAs in association with cervical cancer in the Mexican American population. We conducted a pilot study of genome-wide CNA analysis using 2.5 million markers in four diagnostic groups: reference (n = 125, low grade dysplasia (cervical intraepithelial neoplasia (CIN-I, n = 4, high grade dysplasia (CIN-II and -III, n = 5 and invasive carcinoma (squamous cell carcinoma (SCC, n = 5 followed by data analyses using Partek. We observed a statistically-significant difference of CNA burden between case and reference groups of different sizes (>100 kb, 10–100 kb and 1–10 kb of CNAs that included deletions and amplifications, e.g., a statistically-significant difference of >100 kb deletions was observed between the reference (6.6% and pre-cancer and cancer (91.3% groups. Recurrent aberrations of 98 CNA regions were also identified in cases only. However, none of the CNAs have an impact on cancer progression. A total of 32 CNA regions identified contained tumor suppressor genes and oncogenes. Moreover, the pathway analysis revealed endometrial cancer and estrogen signaling pathways associated with this cancer (p < 0.05 using Kyoto Encyclopedia of Genes and Genomes (KEGG. This is the first report of CNAs identified for cervical cancer in the U.S. Latino population using high density markers. We are aware of the small sample size in the study. Thus, additional studies with a larger sample are needed to confirm the current findings.

    The annexins (ANXs) have diverse roles in tumor development and progression, however, their clinical significance in cervical cancer has not been elucidated. The present study was to investigate the clinical significance of annexin A2 (ANXA2) and annexin A4 (ANXA4) expression in cervical cancer. ANXA2 and ANXA4 immunohistochemical staining were performed on a cervical cancer tissue microarray consisting of 46 normal cervical epithelium samples and 336 cervical cancer cases and compared the data with clinicopathological variables, including the survival of cervical cancer patients. ANXA2 expression was lower in cancer tissue (p = 0.002), whereas ANXA4 staining increased significantly in cancer tissues (p < 0.001). ANXA2 expression was more prominent in squamous cell carcinoma (p < 0.001), whereas ANXA4 was more highly expressed in adeno/adenosquamous carcinoma (p < 0.001). ANXA2 overexpression was positively correlated with advanced cancer phenotypes, whereas ANXA4 expression was associated with resistance to radiation with or without chemotherapy (p = 0.029). Notably, high ANXA2 and ANXA4 expression was significantly associated with shorter disease-free survival (p = 0.004 and p = 0.033, respectively). Multivariate analysis indicated that ANXA2+ (HR = 2.72, p = 0.003) and ANXA2+/ANXA4+ (HR = 2.69, p = 0.039) are independent prognostic factors of disease-free survival in cervical cancer. Furthermore, a random survival forest model using combined ANXA2, ANXA4, and clinical variables resulted in improved predictive power (mean C-index, 0.76) compared to that of clinical-variable-only models (mean C-index, 0.70) (p = 0.006). These findings indicate that detecting ANXA2 and ANXA4 expression may aid the evaluation of cervical carcinoma prognosis.

    Metastasis of malignant tumors to the kidney is clinically rare and often discovered by autopsy. Primary lymphoma and lung cancer are known that can metastasize to the kidney. Other malignant tumor metastasis to the kidney is very unusual. Primary cervical cancer metastasis to adjacent pelvic organs and lymph nodes are well known followed by abdominal solid organs such as the liver and adrenal glands. However, reported primary cervical cancer metastasis to the kidney is extremely rare and mostly appeared as bilateral multiple renal masses. We report here on a rare case of unilateral single renal metastasis from primary cervical cancer after concur- rent chemoradiotherapy.

    To determine the prevalence and genotype distribution of human papillomavirus (HPV) infection among Chinese patients with mucopurulent cervicitis (MPC) or cervical cancer (CC). In total, 191 cases of CC (n=66), acute MPC (n=84), and healthy cervix controls (n=41) were initially included; samples were collected between May 21, 2008, and October 9, 2011. Cervical specimens were screened for HPV using a nested polymerase chain reaction assay and DNA sequencing. Overall prevalence of HPV infection was 20.0% in the control group, 53.3% in the MPC group, and 93.8% in the CC group. The predominant genotype detected in all 3 groups was the oncogenic variant HPV 16 (87.7%, 18.7%, and 10.0% in the CC, MPC and control specimens, respectively). The second most frequent genotype among patients with MPC was HPV 58. This variant is also oncogenic and was detected at a higher rate in the MPC group (9.3%) than in the control (2.5%) and CC (1.5%) groups. Infection with HPV was prevalent among Chinese women with MPC or CC. Furthermore, the high prevalence of oncogenic genotypes observed among HPV-positive patients with MPC suggests that this group is at increased risk of developing CC. Copyright © 2012.

    Full Text Available Abstract Background The proven benefit of integrating cervical cancer screening programme into HIV care has led to its adoption as a standard of care. However this is not operational in most HIV clinics in Nigeria. Of the various reasons given for non-implementation, none is backed by scientific evidence. This study was conducted to assess the willingness and acceptability of cervical cancer screening among HIV positive Nigerian women. Methods A cross sectional study of HIV positive women attending a large HIV treatment centre in Lagos, Nigeria. Respondents were identified using stratified sampling method. A pretested questionnaire was used to obtain information by trained research assistants. Obtained information were coded and managed using SPSS for windows version 19. Multivariate logistic regression model was used to determine independent predictor for acceptance of cervical cancer screening. Results Of the 1517 respondents that returned completed questionnaires, 853 (56.2% were aware of cervical cancer. Though previous cervical cancer screening was low at 9.4%, 79.8% (1210 accepted to take the test. Cost of the test (35.2% and religious denial (14.0% were the most common reasons given for refusal to take the test. After controlling for confounding variables in a multivariate logistic regression model, having a tertiary education (OR = 1.4; 95% CI: 1.03-1.84, no living child (OR: 1.5; 95% CI: 1.1-2.0, recent HIV diagnosis (OR: 1.5; 95% CI: 1.1-2.0 and being aware of cervical cancer (OR: 1.5; 95% CI: 1.2-2.0 retained independent association with acceptance to screen for cervical cancer. Conclusions The study shows that HIV positive women in our environment are willing to screen for cervical cancer and that the integration of reproductive health service into existing HIV programmes will strengthen rather than disrupt the services.

    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 goal of cervical screening is to detect and treat precancers before some become cancer. We wanted to understand why, despite state-of-the-art methods, cervical cancers occured in relationship to programmatic performance at Kaiser Permanente Northern California (KPNC), where >1,000,000 women aged ≥30years have undergone cervical cancer screening by triennial HPV and cytology cotesting since 2003. We reviewed clinical histories preceding cervical cancer diagnoses to assign "causes" of cancer. We calculated surrogate measures of programmatic effectiveness (precancers/(precancers and cancers)) and diagnostic yield (precancers and cancers per 1000 cotests), overall and by age at cotest (30-39, 40-49, and ≥50years). Cancer was rare and found mainly in a localized (treatable) stage. Of 623 cervical cancers with at least one preceding or concurrent cotest, 360 (57.8%) were judged to be prevalent (diagnosed at a localized stage within one year or regional/distant stage within two years of the first cotest). Non-compliance with recommended screening and management preceded 9.0% of all cancers. False-negative cotests/sampling errors (HPV and cytology negative), false-negative histologic diagnoses, and treatment failures preceded 11.2%, 9.0%, and 4.3%, respectively, of all cancers. There was significant heterogeneity in the causes of cancer by histologic category (pstate-of-the-art intensive screening program results in very few cervical cancers, most of which are detected early by screening. Screening may become less efficient at older ages. Copyright © 2017 Elsevier Inc. All rights reserved.

    Cervical cancer is the second most common cancer in women in developing countries, including India. Recently, microRNAs (miRNAs) are gaining importance in cancer biology because of their involvement in various cellular processes. The present study aimed to profile miRNA expression pattern in cervical cancer, identify their target genes, and understand their role in carcinogenesis. Human papillomavirus (HPV) infection statuses in samples were assessed by heminested polymerase chain reaction followed by direct DNA sequencing. Next-generation sequencing and miRNA microarray were used for miRNA profiling in cervical cancer cell lines and tissue samples, respectively. MicroRNA signature was validated by quantitative real-time PCR, and biological significance was elucidated using various in silico analyses. Cervical cancer tissues samples were mostly infected by HPV type 16 (93%). MicroRNA profiling showed that the pattern of miRNA expression differed with respect to HPV positivity in cervical cancer cell lines. However, target and pathway analyses indicated identical involvement of these significantly deregulated miRNAs in HPV-positive cervical cancer cell lines irrespective of type of HPV infected. Microarray profiling identified a set of miRNAs that are differentially deregulated in cervical cancer tissue samples which were validated using quantitative real-time PCR. In silico analyses revealed that the signature miRNAs are mainly involved in PI3K-Akt and mTOR pathways. The study identified that high-risk HPV induces similar carcinogenic mechanism irrespective of HPV type. The miRNA signature of cervical cancer and their target genes were also elucidated, thereby providing a better insight into the molecular mechanism underlying cervical cancer development.

    It has a good application prospect to predict effects of radiotherapy by examining radiosensitivity of patients with cervical cancers before their radiotherapy. Prediction of tumor cell radiosensitivity according to their level of gene expression and gene therapy to reverse radio-resistance prior to radiation on cervical cancers are heated researches on tumor therapy. The expression of some proliferation-related genes, apoptosis-related genes and hypoxia-related genes can inerease the radiosensitivity of cervical cancer. Microarray technology may have more direct applications to the study of biological pathway contributing to radiation resistance and may lead to development of alternative treatment modalities.

    Brushes (Cytobrush, Medscand) are superior to swabs for the collection of endocervical cells for cytologic examination. In the present randomized study, Cytobrush was compared with ENT-swabs and with white, cotton-tipped swabs to obtain samples for the diagnosis of chlamydial cervicitis. The women were examined for the presence of mucopurulent cervicitis (MPC). The subjects comprised 126 women, most of whom had been referred because of asymptomatic chlamydial infection. Specimens obtained with brushes were culture-positive in 83 women and positive in a direct fluorescent antibody test (FA-test) in 78 women. The corresponding figures for samples obtained with swabs were 80 and 74, respectively. The mean number of inclusions was significantly higher in samples obtained with brushes (4,999), compared with swabs (3,155), as was the mean number of elementary bodies (3,000 vs 2,481). MPC was detected in 65% of the women with asymptomatic chlamydial cervicitis, and in 93% of those with symptomatic infection. The corresponding figures for a pathologic wet smear were 62% and 80%, respectively. The specificity and predictive values of a positive and negative MPC-test was 21%, 39%, and 86%, respectively, and for a pathologic wet smear 53%, 44%, and 85%, respectively. We conclude that brushes are superior to swabs for sampling material, both for culture and for direct FA-tests. The MPC and the wet smear tests could be of value in the diagnosis of chlamydial cervicitis, providing confirmatory laboratory tests are used.

    Cervical cancer is the second most common cancer in women worldwide, with about 500,000 new cases and 270,000 deaths each year. Globally, it is estimated that over one million women currently have cervical cancer, most of whom have not been diagnosed, or have no access to treatment that could cure them or prolong their lives. In the United Arab Emirates (UAE) cervical cancer is the third most common cancer in women. A population-based cross-sectional retrospective survey of cervical smear abnormalities was conducted in the Emirate of Abu Dhabi, UAE, from January 2013 to December 2013 by collecting consecutive liquid-based cytology samples from the Department of Pathology at the SKMC Hospital in Abu Dhabi city. The total number of women screened for cervical cancer for the year 2013 at SKMC was 4,593, with 225 (4.89%) abnormal smears. The majority of the abnormal smear results were atypical squamous cells of undetermined significance (ASCUS) 114 (2.48%). This study showed 60% increase in the rate of abnormal cervical smears in the UAE over the last 10 years. In this study the highest incidence of high grade abnormalities were seen in women above the age of 61 years (1.73%), this might be due to the fact that this group of women missed the chance of screening of cervical cancer earlier in their lives or could be explained by the well-known second peak of HPV infection seen in many prevalence studies. We conclude that the rate of abnormal cervical smear in the screened Abu Dhabi women is not different from the rate in developed countries. A notable increase in both low and high grade abnormalities has occurred within the last decade.

    Full Text Available Abstract Background Cervical cancer is the commonest cancer of women in Uganda. Over 80% of women diagnosed in Mulago national referral and teaching hospital, the biggest hospital in Uganda, have advanced disease. Pap smear screening, on opportunistic rather than systematic basis, is offered free in the gynaecological outpatients clinic and the postnatal/family planning clinics. Medical students in the third and final clerkships are expected to learn the techniques of screening. Objectives of this study were to describe knowledge on cervical cancer, attitudes and practices towards cervical cancer screening among the medical workers of Mulago hospital. Methods In a descriptive cross-sectional study, a weighted sample of 310 medical workers including nurses, doctors and final year medical students were interviewed using a self-administered questionnaire. We measured knowledge about cervical cancer: (risk factors, eligibility for screening and screening techniques, attitudes towards cervical cancer screening and practices regarding screening. Results Response rate was 92% (285. Of these, 93% considered cancer of the cervix a public health problem and knowledge about Pap smear was 83% among respondents. Less than 40% knew risk factors for cervical cancer, eligibility for and screening interval. Of the female respondents, 65% didn't feel susceptible to cervical cancer and 81% had never been screened. Of the male respondents, only 26% had partners who had ever been screened. Only 14% of the final year medical students felt skilled enough to use a vaginal speculum and 87% had never performed a pap smear. Conclusion Despite knowledge of the gravity of cervical cancer and prevention by screening using a Pap smear, attitudes and practices towards screening were negative. The medical workers who should be responsible for opportunistic screening of women they care for are not keen on getting screened themselves. There is need to explain/understand the cause

    The purpose was to investigate the potential value of apparent diffusion coefficient (ADC) measurement with MRI in the assessment of cervix cancer. Diffusion-weighted MRI was performed in 47 patients with cervical carcinoma undergoing chemoradiation therapy and 26 normal controls on a 1.5-T system with a b-value of 600 s/mm 2 . FIGO stage, tumor volume, nodal status, interstitial fluid pressure (IFP) and oxygen measurements were recorded. Response was defined as no visible tumor 3-6 months following completion of therapy. The average median ADC (mADC) of cervical carcinomas (1.09±0.20 x 10 -3 mm 2 /s) was significantly lower than normal cervix (2.09±0.46 x 10 -3 mm 2 /s) (P -3 mm 2 /s) compared to T2b (1.21 x 10 -3 mm 2 /s) and T3/T4 (1.10 x 10 -3 mm 2 /s) (P<0.001). In patients with squamous carcinomas the 90th percentile of ADC values was lower in responders than non-responders (P<0.05). Median ADC in cervix carcinoma is significantly lower compared to normal cervix. ADC may have predictive value in squamous tumors, but further long-term study will determine the ultimate clinical utility. (orig.)

    Our previous study reported that MEG3 is an important tumor suppressor gene that is inactivated in cervical cancer. However, the diagnostic and prognostic values of MEG3, as well as the molecular mechanism of MEG3 inactivation in cervical cancer, remain unclear. In this study, we aimed to further elucidate the role and potential inactivation mechanism of MEG3 in cervical cancer. ROC curve and Cox regression analyses were used to assess the diagnostic and prognostic value of MEG3 in patients with cervical cancer. The methylation status of the MEG3 promoter in cervical cancer tissue samples was tested using methylation-specific PCR. Furthermore, we altered the methylation status of the MEG3 promoter in two cervical cancer cell lines (HeLa and CaSki) using a DNA methylation transfer enzyme inhibitor (5-Aza-CdR), to investigate whether promoter hypermethylation is a potential cause of MEG3 inactivation. Finally, we used CCK-8 and colony formation assays to evaluate the cell proliferation ability of HeLa and CaSki cells that had been treated with 5-aza-CdR, to investigate whether downregulation of MEG3 caused by promoter hypermethylation had biological effects. ROC curve analysis indicated that MEG3 status showed sufficient sensitivity and specificity for prediction of tumor size and lymph node metastasis in patients with cervical cancer. In addition, our follow-up data showed that low MEG3 expression was correlated with recurrence and short overall survival. Moreover, hypermethylation of the MEG3 promoter was observed in most cervical cancer tissue samples, and demethylation of the MEG3 promoter led to re-expression of MEG3 and inhibited proliferation of HeLa and CaSki cells. MEG3 is a powerful tool for diagnosis and prognosis of patients with cervical cancer, and low expression of MEG3 is likely to be related to promoter hypermethylation in cervical cancer.

    The characteristics of two prophylactic Human Papilloma Virus HPV vaccines and ethical issues related to HPV vaccination are reviewed in this paper. These vaccines have the potential of substantially reducing HPV-related morbidity and mortality, and in particular cervical cancer. The vaccines cannot treat women with current HPV infection or HPV related disease. They should be administered before the commencement of sexual activity. The ideal age group is adolescent girls between the ages 9-13. Both vaccines are highly efficacious and immunogenic and induce high levels of serum antibodies after three doses for all vaccine-related HPV types. School-based vaccination is considered as a costeffective method for its delivery. Adequate education of both clinicians and patients is an essential to ensure effective implementation when considering a national vaccination program. (author)

    The acquisition of human papillomavirus (HPV), the most important etiological agent of cervical cancer, does not cause clinical complaints. Although HPV spreads together with agents causing pelvic inflammatory disease (PID) with complaints forcing the patient to seek medical advice, PID has not yet been evaluated as a predictor of cervical cancer. The present study aimed to determine the relationship between PID and HPV in order to evaluate the possible risk factor role of PID for cervical cancer. Two groups of patients were studied: (i) 2,215 women with PID; (ii) 4,217 women participating in a cervical cancer screening programme who were found to have cytological atypia, mucopurulent cervicitis or other colposcopically detected disorders but were free of symptoms of PID. The presence of HPV and other STD agents in cervical smears was detected with polymerase-chain reaction. HPV prevalence was 33.74% in patients with PID and 26.40% in the group of women without PID (p cervical cancer.

    Conventional treatment of cervical cancer, such as radical hysterectomy with lymphadenectomy or pelvic exenteration, is limited to the pelvis. Standard radio-therapeutic treatment is a combination of external-beam radiotherapy to the pelvis and intracavitary applications. However, there is a group of patients for whom external radiotherapy alone has limitations. This group consists primarily of patients with large pelvic lymph nodes containing metastatic cancer, metastatically involved paraaortic lymph nodes outside the usual pelvic radiation field, or large central tumors with parametrial involvement. In patients with cancer of the cervix, the incidence of metastasis to paraaortic lymph nodes is high. Attempts to treat paraaortic nodes with external radiotherapy have resulted in high complication rates because the treatment field includes the highly sensitive gastrointestinal tract. External radiation therapy after retroperitoneal exploration of lymph nodes does not seem to improve survival. In an attempt to circumvent the morbidity and mortality associated with conventional external-beam irradiation, the authors initiated a pilot study of intraoperative electron-beam irradiation of the paraaortic nodes and of the large metastatic lymph nodes in the pelvis. The intraoperative boost was followed by conventional fractionated external-beam irradiation. The theoretical advantages of this procedure include a higher radiation tumor dose without a concomitant increase in treatment morbidity and mortality

    Many refugees in the United States emigrated from countries where the incidence of cervical cancer is high. Refugee women are unlikely to have been screened for cervical cancer prior to resettlement in the U.S. National organizations recommend cervical cancer screening for refugee women soon after resettlement. We sought to identify health and social service providers' perspectives on promoting cervical cancer screening in order to inform the development of effective programs to increase screening among recently resettled refugees. This study consisted of 21 in-depth key informant interviews with staff from voluntary refugee resettlement agencies, community based organizations, and healthcare clinics serving refugees in King County, Washington. Interview transcripts were analyzed to identify themes. We identified the following themes: (1) refugee women are unfamiliar with preventive care and cancer screening; (2) providers have concerns about the timing of cervical cancer education and screening; (3) linguistic and cultural barriers impact screening uptake; (4) provider factors and clinic systems facilitate promotion of screening; and (5) strategies for educating refugee women about screening. Our findings suggest that refugee women are in need of health education on cervical cancer screening during early resettlement. Frequent messaging about screening could help ensure that women receive screening within the early resettlement period. Health education videos may be effective for providing simple, low literacy messages in women's native languages. Appointments with female clinicians and interpreters, as well as clinic systems that remind clinicians to offer screening at each appointment could increase screening among refugee women.

    Cervical cancer usually presents in advanced stages and is treated with chemoradiation. About 15-20 % patients present with local recurrence after chemoradiation. Radical surgical resection is the only treatment modality offering long term survival benefit in recurrent cervical cancer. The most common surgical option for these patients is pelvic exenteration. Radical hysterectomy may be done for patients with a small centrally located recurrence in the cervix with no infiltration of adjacent structures. The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy and pelvic exenteration for recurrent cancer cervix. We retrospectively reviewed the medical records of our patients who underwent surgery for cancer cervix recurrence from January 2010 to December 2014. The postoperative morbidity was considered early if it happened in the initial 30 days of surgery and late if it occurred after 30 days. All patients were followed up till February 2015. Survival analysis was done using Kaplan- Meir method. Between January 2010 and December 2014, 20 patients with recurrent cervical cancer underwent radical surgical resection. The median age of the study group was 43 years (range 28-63 years). Seventeen patients had squamous cell carcinoma and 3 had adenocarcinoma. 13 underwent pelvic exenteration and 7 patients underwent radical type 2 hysterectomy with bilateral pelvic lymphnode dissection. In the exenteration group, 8 patients had anterior exenteration, 4 had total exenteration and one had posterior exenteration. Urinary diversion was done by ileal conduit in 8 patients, double barrel colostomy in two and wet colostomy in two patients. There were no immediate postoperative deaths. Operating time, blood transfusions needed and hospital stay was more in the exenteration group compared to radical hysterectomy patients. After pelvic exenteration post-operative complications were seen in 76.9 % of which the most common was of

    In Uyghur women, mortality rates from cervical cancer are amongst the highest in the nation, and genetic susceptibility probably plays a role in the pathogenesis of the disease. We investigated the correlation between polymorphisms of the HLA-DQB1 allele and cervical cancer in Xinjiang Uyghur women. Cervix tissue samples from 80 cases of cervical cancer and 80 cases of cervicitis were genotyped using polymerase chain reaction-sequence-based typing (PCR-SBT) for HLA-DQB1. Two hundred and ninety-six alleles were identified among the 160 cases. One hundred and thirty-six alleles were heterozygous and 24 were homozygous. Using frequency calculations and statistical analysis, we found that HLA-DQB1*0325 (OR: 10.60, 1.341-83.81) and HLA-DQB1*0332 (OR: 12.59, 2.909-54.526) were more frequently identified in the cervical cancer group compared with the cervicitis group (P HLA-DQB1*0317 (OR: 0.49, 0.304-0.798) and HLA-DQB1*040302 (OR: 0.40, 0.243-0.658) were present less frequently in the cervical cancer group (P HLA-DQB1 genotype in Uyghur was different from that reported previously in other areas. HLA-DQB1*0325 and HLA-DQB1*0332 probably act as cervical cancer susceptibility genes in Uyghur women from Xinjiang. In contrast, HLA-DQB1*0317 and HLA-DQB1*040302 may be protective genes.

    In this study, we investigated the consensus gene modules in head and neck cancer (HNC) and cervical cancer (CC). We used a publicly available gene expression dataset, GSE6791, which included 42 HNC, 14 normal head and neck, 20 CC and 8 normal cervical tissue samples. To exclude bias because of different human papilloma virus (HPV) types, we analyzed HPV16-positive samples only. We identified 3824 genes common to HNC and CC samples. Among these, 977 genes showed high connectivity and were used to construct consensus modules. We demonstrated eight consensus gene modules for HNC and CC using the dissimilarity measure and average linkage hierarchical clustering methods. These consensus modules included genes with significant biological functions, including ATP binding and extracellular exosome. Eigengen network analysis revealed the consensus modules were highly preserved with high connectivity. These findings demonstrate that HPV16-positive head and neck and cervical cancers share highly preserved consensus gene modules with common potentially therapeutic targets.

    Most female-to-male (FTM) transgender men retain their cervixes and need comprehensive sexual health care, including cervical cancer screening. According to the literature, FTM individuals obtain cervical cancer screening less frequently and are less likely to be up to date on their Pap tests compared with cisgender women. Misinformation related to human papillomavirus and cervical cancer risk was noted for health care providers and FTM individuals. Absence of transgender-specific guidelines or trained health care providers presents barriers to cervical cancer screening for FTM individuals, and further research is indicated to develop comprehensive guidelines unique to the needs and experiences of this population. © 2018 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    Full Text Available Cervical cancer is a common cancer inflicting women worldwide. Even though, persistent infection with oncogenic Human Papillomavirus (HPV types is considered the most important risk factor for cervical cancer development, less than 5% of women with HPV will eventually develop cervical cancer supporting that other molecular events, like methylation-dependent inactivation of tumor suppressor genes, may cocontribute in cervical carcinogenesis. We analyzed promoter methylation of three candidate genes (p16, MGMT, and hMLH1 in 403 liquid-based cytology samples. Methylation was commonly identified in both benign and pathologic samples and correlated with higher lesion grade determined by cytological, colposcopical, or histological findings, with HPV DNA and mRNA positivity of specific HPV types and p16INK4A protein expression. Overall accuracy of methylation is much lower than traditional diagnostic tests ranking it as an ancillary technique with more data needed to identify the exact value of methylation status in cervical carcinogenesis.

    Full Text Available Abstract Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively. Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

    Tumor cells may develop multidrug resistance (MDR) to various chemotherapy regimens. Such resistance reduces the sensitivity of cells to chemotherapy drugs, leading to the failure of cervical cancer (CC) treatment and disease progression. The present study aimed to investigate the role of MDR1, lung resistance protein (LRP) and placental glutathione S‑transferase π 1 (GSTP1) in CC and MDR, and the prognostic value of these genes. The mRNA expression levels of these resistance‑associated genes were determined in 47 CC and 20 healthy cervical tissue samples. Subsequently, the data was analyzed alongside clinicopathological parameters. The mRNA expression levels of MDR1, LRP and GSTP1 in CC were 0.57±0.32, 0.58±0.29 and 0.44±0.24, respectively, whereas those in healthy cervical tissues were 0.19±0.10, 0.17±0.14 and 0.18±0.10, respectively. Therefore, the expression levels of these genes were significantly greater in CC compared with healthy cervical tissue (PMRD1 were increased in the well differentiated group (0.68±0.27) compared with the poorly differentiated group (0.38±0.33; P0.05). Multivariate logistic regression indicated that the degree of differentiation and the MDR1 gene expression levels were predictors of CC prognosis (P<0.05). The survival rate of patients in the MDR1‑negative group was significantly greater compared with the MDR1‑positive group (P<0.05). The results of the present study therefore suggested that MDR1 gene expression is a predictor of poor survival in CC.

    Although the relationship between human papilloma virus (HPV) and cervical cancer is well established, the prognostic value of HPV status has not been determined, largely because previous studies have yielded conflicting results. This study aimed to investigate the prognostic value of pre-treatment HPV DNA for predicting tumor recurrence in cervical cancer. The study included 248 eligible patients who provided cervical cell specimens for HPV genotyping before surgery or concurrent chemoradiotherapy (CCRT). Of these 248 patients, 108 were treated with radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage IB1-IIA cervical cancer, and 140 were treated with CCRT for FIGO stage IB2-IV cervical cancer. HPV 16 and 18 were the two most common HPV types detected, with prevalence rates of 52.4% and 12.5%, respectively. The pre-treatment HPV DNA test showed that 18.5% of cervical cancers were HPV negative. Multivariate analysis showed that HPV negativity was associated with poorer disease-free survival (DFS) than HPV-positive status (hazard ratio [HR], 3.97; 95% confidence interval [CI], 1.84-8.58; p=0.0005), and patients with HPV 16-positive cancers had better DFS (HR, 0.41; 95% CI, 0.23-0.72; p=0.0019). In the surgery group, only HPV 16 positivity was significantly correlated with DFS (HR, 0.34; 95% CI, 0.12-0.96; p=0.0416). In the CCRT group, only HPV negativity was significantly correlated with DFS (HR, 3.75; 95% CI, 1.78-7.90; p=0.0005). Pre-treatment HPV DNA status may be a useful prognostic biomarker in cervical cancer. The presence of HPV 16 DNA was associated with better DFS, and HPV negativity was associated with worse DFS. However, larger sample sizes and more comprehensive studies are required to verify our findings. Copyright © 2017 Elsevier Inc. All rights reserved.

Patients and methods: One hundred fifteen outpatients with cervical cancer in the First Affiliated Hospital of Xinxiang Medical University from May 2013 to July 2013 were included in this study. All participants self-administered the EORTC QLQ-CX24 and the core questionnaire (EORTC QLQ-C30, and the Karnofsky Performance Scale was performed to evaluate scores. Data were analyzed with Cronbach’s α coefficient, Pearson correlation test, multitrait scaling analysis, and Mann–Whitney U test. Results: Scale reliability was confirmed by Cronbach’s α coefficients for internal consistency, which ranged from 0.71 to 0.82. Convergent and discriminant validity were confirmed by multitrait scaling analysis, which revealed three (3.4% scaling errors for symptom experience scales and zero (0% for body image as well as sexual/vaginal functioning scales. Higher missing value rate occurred in sexuality-related items. The clinical validity of the Chinese version of the EORTC QLQ-CX24 was demonstrated by the ability to discriminate among patients in different International Federation of Gynecology and Obstetrics stages. Conclusion: The EORTC QLQ-CX24 was proved to be a reliable and valid instrument with which to measure the quality of life in cervical cancer patients in the People’s Republic of China.

Two cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40-69 at first cytology, and 14,668 women aged ≥70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ≥66 with and without cytology in the year prior to diagnosis. There were 259 cancers diagnosed in women aged 40-69 at first cytology, and 78 in women aged ≥70. The sensitivity of cytology ≥ HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355-462) and 226 (95% CI: 177-292) respectively. Women aged ≥66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17-22% reduction in case fatality. Cervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality. © The Author(s) 2015.

    Full Text Available Background: The profiles of lipids in normal and cancerous tissues may differ revealing information about cancer development and progression. Lipids being surface active, changes in lipid profiles can manifest as altered surface activity profiles. Langmuir monolayers offer a convenient model for evaluating surface activity of biological membranes. Aims: The aims of this study were to quantify phospholipids and their effects on surface activity of normal and cancerous human cervical tissues as well as to evaluate the role of phosphatidylcholine (PC and sphingomyelin (SM in cervical cancer using Langmuir monolayers. Methods and Materials: Lipid quantification was done using thin layer chromatography and phosphorus assay. Surface activity was evaluated using Langmuir monolayers. Monolayers were formed on the surface of deionized water by spreading tissue organic phase corresponding to 1 mg of tissue and studying their surface pressure-area isotherms at body temperature. The PC and SM contents of cancerous human cervical tissues were higher than those of the normal human cervical tissues. Role of PC and SM were evaluated by adding varying amounts of these lipids to normal cervical pooled organic phase. Statistical analysis: Student′s t-test (p < 0.05 and one-way analysis of variance (ANOVA was used. Results: Our results reveals that the phosphatidylglycerol level in cancerous cervical tissue was nearly five folds higher than that in normal cervical tissue. Also PC and sphingomyelin SM were found to be the major phospholipid components in cancerous and normal cervical tissues respectively. The addition of either 1.5 µg DPPC or 0.5 µg SM /mg of tissue to the normal organic phase changed its surface activity profile to that of the cancerous tissues. Statistically significant surface activity parameters showed that PC and SM have remarkable roles in shifting the normal cervical lipophilic surface activity towards that of cancerous lipophilic

    BACKGROUND: Small cell carcinoma of the cervix is a rare cancer, comprising less than 3% of all cervical neoplasms. It uniformly has a poor prognosis, and has a high mortality even with early stage disease. It can metastasise rapidly and metastatic sites include lung, liver, brain, bone, pancreas and lymph nodes. CASE: Here, we report the case of a 60-year-old woman with no symptoms of cervical pathology who developed post-renal failure following a laparoscopic cholecystectomy. The cause was bilateral ureteric obstruction from metastatic small cell cervical cancer and metastases were subsequently found on her gallbladder specimen. CONCLUSION: This is an unusual presentation of small cell cervical cancer and demonstrates the aggressive nature of this disease.

    Cervical cancer screening is an effective method for reducing the incidence and mortality of cervical cancer, but the screening attendance rate in developing countries is far from satisfactory, especially in rural areas. Wufeng is a region of high cervical cancer incidence in China. This study aimed to investigate the issues that concern cervical cancer and screening and the factors that affect women's willingness to undergo cervical cancer screening in the Wufeng area. A cross-sectional survey of women was conducted to determine their knowledge about cervical cancer and screening, demographic characteristics and the barriers to screening. Women who were willing to undergo screenings had higher knowledge levels. "Anxious feeling once the disease was diagnosed" (47.6%), "No symptoms/discomfort" (34.1%) and "Do not know the benefits of cervical cancer screening" (13.4%) were the top three reasons for refusing cervical cancer screening. Women who were younger than 45 years old or who had lower incomes, positive family histories of cancer, secondary or higher levels of education, higher levels of knowledge and fewer barriers to screening were more willing to participate in cervical cancer screenings than women without these characteristics. Efforts are needed to increase women's knowledge about cervical cancer, especially the screening methods, and to improve their perceptions of the screening process for early detection to reduce cervical cancer incidence and mortality rates.

    Background and purpose: We investigated the effects of socio-demographic, treatment- and tumor-specific determinants on the risk of developing a second malignancy among patients treated for cervical cancer. Material and methods: We included patients with a first cervical cancer (N = 12,048) from the Netherlands Cancer Registry (NCR), 1989–2008. Standardized incidence ratios (SIR) and absolute excess risks (AER) per 10,000 person-years were calculated to estimate the burden of second cancers in cervical cancer survivors. Incidence rate ratios (IRR) were computed to identify predictors for second cancers among cervical cancer survivors. Results: During the study period, 676 (5.6%) patients were diagnosed with a second cancer. Smoking-related cancers contributed the most to the overall burden of second cancers (AER = 21) and risks remained elevated after 10 years of follow-up (SIR = 1.8, 95% CI: 1.4–2.2), yet it decreased markedly in the younger birth cohorts. Cervical cancer survivors who underwent radiotherapy were at higher risk for a second tumor when compared to those without radiotherapy, especially at smoking-related sites (IRR = 1.6 (1.2–2.3)). Conclusion: Patients with cervical cancer had a significantly increased risk for a second cancer compared to the general population, especially for smoking- and irradiation-related tumors. Long-term follow-up suggested the importance of smoking cessation and the benefits of counseling cervical cancer patients accordingly, particularly those who received radiotherapy

    Full Text Available The HPV types that cause cervical cancer are sexually transmitted, but there is little evidence that infection can be avoided by behavioural changes, such as condom use. In contrast, prophylactic vaccines against HPV infection are likely to have high efficacy. In principle, the effectiveness of HPV vaccination as a strategy for cervical cancer control can be measured either by monitoring secular trends in cervical cancer incidence or by conducting randomized trials. The former approach is unlikely to provide convincing evidence of effectiveness, since cervical cancer rates are subject to strong secular trends that are independent of intervention measures. A few phase III trials of HPV prophylactic vaccines are now being started. Such trials are very expensive studies involving frequent and complicated investigations. It is important, however, to start as soon as possible simpler trials designed to demonstrate the effectiveness of HPV vaccine in field conditions, i.e. in developing or intermediate countries which suffer the major burden of mortality from cervical cancer. Such trials may capture a difference in the most severe, and rarest, preinvasive cervical lesions (i.e., the real target of any HPV vaccine over a prolonged follow-up (20 years at least. The design of such studies is briefly considered for two areas: Southern India and South Korea.

    Purpose: To present a novel brachytherapy technique, called multihelix rotating shield brachytherapy (H-RSBT), for the precise angular and linear positioning of a partial shield in a curved applicator. H-RSBT mechanically enables the dose delivery using only linear translational motion of the radiation source/shield combination. The previously proposed approach of serial rotating shield brachytherapy (S-RSBT), in which the partial shield is rotated to several angular positions at each source dwell position [W. Yang et al., “Rotating-shield brachytherapy for cervical cancer,” Phys. Med. Biol. 58, 3931–3941 (2013)], is mechanically challenging to implement in a curved applicator, and H-RSBT is proposed as a feasible solution. Methods: A Henschke-type applicator, designed for an electronic brachytherapy source (Xoft Axxent™) and a 0.5 mm thick tungsten partial shield with 180° or 45° azimuthal emission angles and 116° asymmetric zenith angle, is proposed. The interior wall of the applicator contains six evenly spaced helical keyways that rigidly define the emission direction of the partial radiation shield as a function of depth in the applicator. The shield contains three uniformly distributed protruding keys on its exterior wall and is attached to the source such that it rotates freely, thus longitudinal translational motion of the source is transferred to rotational motion of the shield. S-RSBT and H-RSBT treatment plans with 180° and 45° azimuthal emission angles were generated for five cervical cancer patients with a diverse range of high-risk target volume (HR-CTV) shapes and applicator positions. For each patient, the total number of emission angles was held nearly constant for S-RSBT and H-RSBT by using dwell positions separated by 5 and 1.7 mm, respectively, and emission directions separated by 22.5° and 60°, respectively. Treatment delivery time and tumor coverage (D{sub 90} of HR-CTV) were the two metrics used as the basis for evaluation and

  10. Somatic LKB1 mutations promote cervical cancer progression.

    Full Text Available Human Papilloma Virus (HPV is the etiologic agent for cervical cancer. Yet, infection with HPV is not sufficient to cause cervical cancer, because most infected women develop transient epithelial dysplasias that spontaneously regress. Progression to invasive cancer has been attributed to diverse host factors such as immune or hormonal status, as no recurrent genetic alterations have been identified in cervical cancers. Thus, the pressing question as to the biological basis of cervical cancer progression has remained unresolved, hampering the development of novel therapies and prognostic tests. Here we show that at least 20% of cervical cancers harbor somatically-acquired mutations in the LKB1 tumor suppressor. Approximately one-half of tumors with mutations harbored single nucleotide substitutions or microdeletions identifiable by exon sequencing, while the other half harbored larger monoallelic or biallelic deletions detectable by multiplex ligation probe amplification (MLPA. Biallelic mutations were identified in most cervical cancer cell lines; HeLa, the first human cell line, harbors a homozygous 25 kb deletion that occurred in vivo. LKB1 inactivation in primary tumors was associated with accelerated disease progression. Median survival was only 13 months for patients with LKB1-deficient tumors, but >100 months for patients with LKB1-wild type tumors (P = 0.015, log rank test; hazard ratio = 0.25, 95% CI = 0.083 to 0.77. LKB1 is thus a major cervical tumor suppressor, demonstrating that acquired genetic alterations drive progression of HPV-induced dysplasias to invasive, lethal cancers. Furthermore, LKB1 status can be exploited clinically to predict disease recurrence.

    OBJECTIVE To analyze cervical and breast cancer mortality in Brazil according to socioeconomic and welfare indicators. METHODS Data on breast and cervical cancer mortality covering a 30-year period (1980-2010) were analyzed. The data were obtained from the National Mortality Database, population data from the Brazilian Institute of Geography and Statistics database, and socioeconomic and welfare information from the Institute of Applied Economic Research. Moving averages were calculated, disaggregated by capital city and municipality. The annual percent change in mortality rates was estimated by segmented linear regression using the joinpoint method. Pearson’s correlation coefficients were conducted between average mortality rate at the end of the three-year period and selected indicators in the state capital and each Brazilian state. RESULTS There was a decline in cervical cancer mortality rates throughout the period studied, except in municipalities outside of the capitals in the North and Northeast. There was a decrease in breast cancer mortality in the capitals from the end of the 1990s onwards. Favorable socioeconomic indicators were inversely correlated with cervical cancer mortality. A strong direct correlation was found with favorable indicators and an inverse correlation with fertility rate and breast cancer mortality in inner cities. CONCLUSIONS There is an ongoing dynamic process of increased risk of cervical and breast cancer and attenuation of mortality because of increased, albeit unequal, access to and provision of screening, diagnosis and treatment.  PMID:25119941

    Full Text Available Purpose: To analyze the optimum organ filling point for organs at risk (OARs dose in cervical cancer high-dose-rate (HDR brachytherapy. Material and methods : In a retrospective study, 32 locally advanced cervical cancer patients (97 insertions who were treated with 3D conformal external beam radiation therapy (EBRT and concurrent chemotherapy during 2010-2013 were included. Rotterdam HDR tandem-ovoid applicators were used and computed tomography (CT scanning was performed after each insertion. The OARs delineation and GEC-ESTRO-based clinical target volumes (CTVs contouring was followed by 3D forward planning. Then, dose volume histogram (DVH parameters of organs were recorded and patients were classified based on their OARs volumes, as well as their inserted tandem length. Results : The absorbed dose to point A ranged between 6.5-7.5 Gy. D 0.1cm ³ and D 2cm ³ of the bladder significantly increased with the bladder volume enlargement (p value < 0.05. By increasing the bladder volume up to about 140 cm3, the rectum dose was also increased. For the cases with bladder volumes higher than 140 cm3, the rectum dose decreased. For bladder volumes lower than 75 cm3, the sigmoid dose decreased; however, for bladder volumes higher than 75 cm3, the sigmoid dose increased. The D 2cm ³ of the bladder and rectum were higher for longer tandems than for shorter ones, respectively. The divergence of the obtained results for different tandem lengths became wider by the extension of the bladder volume. The rectum and sigmoid volume had a direct impact on increasing their D 0.1cm ³ and D 2cm ³, as well as decreasing their D 10 , D 30 , and D 50 . Conclusions : There is a relationship between the volumes of OARs and their received doses. Selecting a bladder with a volume of about 70 cm3 or less proved to be better with regards to the dose to the bladder, rectum, and sigmoid.

    Invasive cervical cancer is the second most common malignant tumor affecting Brazilian women. Knowledge on Human Papillomavirus (HPV) genotypes in invasive cervical cancer cases is crucial to guide the introduction and further evaluate the impact of new preventive strategies based on HPV. We aimed to provide updated comprehensive data about the HPV types’ distribution in patients with invasive cervical cancer. Fresh tumor tissue samples of histologically confirmed invasive cervical cancer were collected from 175 women attending two cancer reference hospitals from São Paulo State: ICESP and Hospital de Câncer de Barretos. HPV detection and genotyping were performed by the Linear Array HPV Genotyping Test (Roche Molecular Diagnostics, Pleasanton,USA). 170 out of 172 valid samples (99%) were HPV DNA positive. The most frequent types were HPV16 (77.6%), HPV18 (12.3%), HPV31 (8.8%), HPV33 (7.1%) and HPV35 (5.9%). Most infections (75%) were caused by individual HPV types. Women with adenocarcinoma were not younger than those with squamous cell carcinoma, as well, as women infected with HPV33 were older than those infected by other HPV types. Some differences between results obtained in the two hospitals were observed: higher overall prevalence of HPV16, absence of single infection by HPV31 and HPV45 was verified in HC-Barretos in comparison to ICESP patients. To our knowledge, this is one of the largest studies made with fresh tumor tissues of invasive cervical cancer cases in Brazil. This study depicted a distinct HPV genotype distribution between two centers that may reflect the local epidemiology of HPV transmission among these populations. Due to the impact of these findings on cervical cancer preventive strategies, extension of this investigation to routine screening populations is warranted

    Cervical cancer prevention knowledge deficits persist among women living with HIV/AIDS (WLHA) despite increased risk of developing cervical dysplasia/cancer. We examined associations between WLHA's cervical cancer prevention knowledge and abnormal Pap test history. We recruited 145 urban and rural WLHA from Ryan White-funded clinics and AIDS service organizations located in the southeastern USA between March 2011 and April 2012. For this analysis, women who reported a history of cervical cancer (n = 3) or had a complete hysterectomy (n = 14) and observations with missing data (n = 22) were excluded. Stata/IC 13 was used to perform cross-tabulations and chi-squared tests. Our sample included 106 predominantly non-Hispanic Black (92%) WLHA. Mean age was 46.3 ± 10.9 years. Half (50%) had ≤ high school education. One third (37%) had low health literacy. The majority (83 %) had a Pap test Pap test every year, once two tests are normal. Many (68%) have had an abnormal Pap test. Abnormal Pap test follow-up care knowledge varied. While 86% knew follow-up care could include a repeat Pap test, only 56% knew this could also include an HPV test. Significantly, more women who had an abnormal Pap test knew follow-up care could include a biopsy (p = 0.001). For WLHA to make informed/shared decisions about their cervical health, they need to be knowledgeable about cervical cancer care options across the cancer control continuum. Providing WLHA with prevention knowledge beyond screening recommendations seems warranted given their increased risk of developing cervical dysplasia/neoplasia.

    Though LIM-domain protein AJUBA was identified as a putative oncogene, the function and underlying mechanisms of AJUBA in cervical cancer remain largely unknown. Firstly, AJUBA expression was detected via real-time quantitative PCR in patients' samples. Furthermore, Hela and Siha cells were transfected with AJUBA-overexpressing plasmids, and then exposed to cisplatin, the apoptosis was measured by cytometry assay. In addition, the expression of YAP and TAZ was disclosed through western blot assay. Our results revealed that AJUBA expression was significantly higher in the cervical cancer patients resistant to cisplatin treatment compared with cervical cancer patients sensitive to cisplatin treatment. In addition, overall survival time was significantly shorter in the cervical cancer patients with high AJUBA expression compare with those with low AJUBA expression using kaplan-meier analysis. Hela and Siha cells transfected with AJUBA-expressing plasmids exposed to cisplatin treatment had higher survival rate compared with the cells transfected with empty vector control. Mechanistic studies revealed the AJUBA upregulated the downstream targets YAP and TAZ. These results suggest that high AJUBA level enhances cervical cancer cells drug resistance to cisplatin, also associates with decreased patient survival times. Copyright © 2017 Elsevier B.V.

    Cervical cancer is a major cause of cancer-related mortality in women in the developing world. Cancer Stem cells (CSC) have been implicated in treatment resistance and metastases development; hence understanding their significance is important. Primary culture from tissue biopsies of invasive cervical cancer and serial passaging was performed for establishing cell lines. Variable Number Tandem Repeat (VNTR) assay was performed for comparison of cell lines with their parental tissue. Tumorsphere and Aldefluor assays enabled isolation of cancer stem cells (CSC); immunofluorescence and flow cytometry were performed for their surface phenotypic expression in cell lines and in 28 tissue samples. Quantitative real-time PCR for stemness and epithelial-mesenchymal transition (EMT) markers, MTT cytotoxicity assay, cell cycle analysis and cell kinetic studies were performed. Four low-passage novel cell lines designated RSBS-9, - 14 and - 23 from squamous cell carcinoma and RSBS-43 from adenocarcinoma of the uterine cervix were established. All were HPV16+. VNTR assay confirmed their uniqueness and derivation from respective parental tissue. CSC isolated from these cell lines showed CD133 + phenotype. In tissue samples of untreated invasive cervical cancer, CD133 + CSCs ranged from 1.3-23% of the total population which increased 2.8-fold in radiation-resistant cases. Comparison of CD133 + with CD133 - bulk population cells revealed increased tumorsphere formation and upregulation of stemness and epithelial-mesenchymal transition (EMT) markers with no significant difference in cisplatin sensitivity. Low-passage cell lines developed would serve as models for studying tumor biology. Cancer Stem Cells in cervical cancer display CD133 + phenotype and are increased in relapsed cases and hence should be targeted for achieving remission.

    Identification of high-risk HPV genotypes in patients is essential for vaccination and prevention programs while the geographic distribution of cervical cancer varies widely. HPV 16 is the major cause of cervical cancer followed by HPV 18, HPV 31, HPV 52, or HPV 58 depending on geographic area. In this study, the distribution of HPV genotypes in cervical specimens from women living in Thailand was analyzed by HPV testing with electrochemical DNA chip and PCR direct sequencing. The 716 specimens were grouped according to their cytological grades; 100 normal, 100 low-grade squamous intraepithelial lesions, 100 high grade squamous intraepithelial lesions, and 416 specimens of cervical cancer. The results showed that HPV 16, HPV 18, HPV 52, and HPV 58 are the most common HPV genotypes in Thailand, respectively. With respect to age, women below the age of 26 years were almost negative for high-risk HPV DNA exclusively. Conversely, high prevalence of high-risk HPV DNA and abnormal cytology were usually found in women between 26 and 45 years while cervical cancer was detected mainly in women above the age of 45 years. To increase protection efficiency, a vaccine including HPV 52 and HPV 58 should be offered to Asian women, and primary HPV screening should start at 26-30 years of age. © 2013 Wiley Periodicals, Inc.

    The incidence of squamous cell cervical cancer was studied in Jewish Israeli women between 1961 and 1981. The 1052 cases and the 27,832,272 women-years of observation were divided according to continent-of-origin, year-of-birth, and immigration-wave cohorts. Age-adjusted odds ratios were calculated for each cohort and compared. The incidence of cervical cancer was shown to have changed according to cohort year of birth, most significantly in women born in Europe and America. The highest risk in this group was seen in women born in 1891-1895 and 1941-1945 and the lowest in women born between 1926 and 1935. A high risk was also observed in all cohorts of North African women. There was a sharp rise in risk for women of all origins born after 1940. Immigration to Israel at a younger age was correlated with reduced risk for cervical cancer. It has been shown that epidemics of sexually transmitted diseases (STDs) are followed in time by epidemics of cervical cancer. Since there was an epidemic of STDs in Israel between 1967 and 1970, our results also suggest that there is a rise in the risk for cervical cancer in women who were sexually active during the epidemic of STDs. Because of the low rates for cervical cancer traditionally observed in Israeli women, routine screening was not done in Israel in the past. Should the relative risk for cervical cancer in women exposed during the 1967-1970 epidemic continue to be high, screening may prove worthwhile.

    Full Text Available Introduction: modern knowledge could protect against cancer for individuals in community with early stage and premalignat state. Screening of cancer is best instrument for early detection of malignancy. Between women’s cancers breast and cervical cancer have more incidence and mortality than other cancers . But could be prevented by simple and cheep screening programs. Despite specific statistics in Iran evidence shows that women’s participation in screening program is poor , so cancers are diagnosed in advanced stage. The purpose of this study was to identify major barriers and motivators for breast and cervical screening . Methods: This survey was a descriptive study in which 400 women participated in health and treatment centers in Yazd. Sampling method was done in two simple and random stages. Data was collected by inventory and questionnaire . Then data were analyzed by SPSS soft ware . Results: Findings showed that 80% of them never refereed to a health provider for clinical breast exam (C B E and only 3% of them did regularly C B E . 46% of them had never done pap smear and only 14.5 % of them did regularly pap smear. The findings showed that major motivators were as follow: advice of health’s personnel , using of contraceptive methods , and awareness of media. Also the major barriers were as follow : Not having knowledge of these exams , not having knowledge of the existence of these centers of education and practice , not having precious health problems , fear of examination , Embarrassment of examination and health providers not to teach them . to consider the most important barriers were propounded which showed that health education role to eliminate barriers for referring women for screening . Discussion: Based on the results of this sample , screening was the least expected . considering barriers and motivators observed it was revealed that health education was required for prevention of common women’s cancers.

    Cervical cancer is one of the most common cancers in women worldwide. The outcome of patients with metastatic cervical cancer is poor. We reviewed the relevant literature concerning the treatment and diagnosis of metastatic cervical cancer. There are two types of metastasis related to different treatments and survival rates: hematogenous metastasis and lymphatic metastasis. Patients with hematogenous metastasis have a higher risk of death than those with lymphatic metastasis. In terms of diagnosis, fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and PET-computed tomography are effective tools for the evaluation of distant metastasis. Concurrent chemoradiotherapy and subsequent chemotherapy are well-tolerated and efficient for lymphatic metastasis. As for lung metastasis, chemotherapy and/or surgery are valuable treatments for resistant, recurrent metastatic cervical cancer and chemoradiotherapy may be the optimal choice for stage IVB cervical cancer. Chemotherapy and bone irradiation are promising for bone metastasis. A better survival is achieved with multimodal therapy. Craniotomy or stereotactic radiosurgery is an optimal choice combined with radiotherapy for solitary brain metastases. Chemotherapy and palliative brain radiation may be considered for multiple brain metastases and other organ metastases. PMID:27171673

    Cervical cancer is the second most common cancer of the female genital tract. There are 2200 newly registered cases of cervical cancer each year in Serbia, out of which 650 women die. The incidence of invasive, advanced cervical cancer has been on decrease, whereas the incidence of "in situ" stage carcinoma increases by 2% per year with tendency of increase in the younger age groups. The first radical abdominal hysterectomy was performed by Ernst Wertheim from Wienna in 1898, whereas Schauta performed the first vaginal hysterectomy in 1902. It was in 1995 when Daniel Dargent introduced radical vaginal trachelectomy combined with laparoscopic lymphadenectomy in order to preserve fertility in cases of initial-invasive stages of cervical cancer (FIGO I A2, I B1). Before choosing the surgical procedure, it is necessary to make a correct preoperative estimation of the stage of disease according to FIGO classification. Apart from gynecologic and rectovaginal examinations, in some cases it is necessary to perform additional examinations such as: cystoscopy, rectoscopy, CT or MRI examination of the pelvis, IVU, chest X-ray etc. The decision can be made only by an experienced gynecologist-surgeon who is able to solve all complications of treatment by himself. There are different surgical procedures for cervical cancer: abdominal, vaginal and combined. Introduction of laparoscopic lymphadenectomy combined with vaginal radical operations, to decrease surgical trauma and preserve fertility, has been of great significance.

    Full Text Available Accurate classification of Pap smear images becomes the challenging task in medical image processing. This can be improved in two ways. One way is by selecting suitable well defined specific features and the other is by selecting the best classifier. This paper presents a nominated texture based cervical cancer (NTCC classification system which classifies the Pap smear images into any one of the seven classes. This can be achieved by extracting well defined texture features and selecting best classifier. Seven sets of texture features (24 features are extracted which include relative size of nucleus and cytoplasm, dynamic range and first four moments of intensities of nucleus and cytoplasm, relative displacement of nucleus within the cytoplasm, gray level cooccurrence matrix, local binary pattern histogram, tamura features, and edge orientation histogram. Few types of support vector machine (SVM and neural network (NN classifiers are used for the classification. The performance of the NTCC algorithm is tested and compared to other algorithms on public image database of Herlev University Hospital, Denmark, with 917 Pap smear images. The output of SVM is found to be best for the most of the classes and better results for the remaining classes.

    New commercially available Human Papillomavirus (HPV) assays need to be evaluated in a variety of cervical screening settings. Cobas HPV Test (cobas) is a real-time PCR-based assay allowing for separate detection of HPV genotypes 16 and 18 and a bulk of 12 other high-risk genotypes. The aim...... years, an extra 11% of women would based on historical data be expected to have a positive cobas test without an underlying cervical intraepithelial lesion grade 3 or worse. Countries with a high prevalence of HPV infections should therefore proceed to primary HPV-based cervical screening with caution....... of the present study, Horizon, was to assess the prevalence of high-risk HPV infections in an area with a high background risk of cervical cancer, where women aged 23-65 years are targeted for cervical screening. We collected 6,258 consecutive cervical samples from the largest cervical screening laboratory...

    Between 1969 and 1985, a total of 298 patients with cervical cancer were treated by radiation therapy at the Department of Radiology, Gunma University Hospital. Another 111 patients were treated with irradiation as a follow up to surgery; 69 for prophylactic reasons and 42 to treat residual tumors. Patients treated with irradiation alone were given a combination of external irradiation to the pelvis and low dose rate intracavitary irradiation. Patients treated post-operatively were given intracavitary electron beam irradiation of the resected end of the vagina, and external irradiation of the entire pelvis. The following results were obtained: In patients treated by radiation therapy alone, the relative 5-year survival rates according to clinical stage were: 108% for patients with stage I cancer, 90% for stage II, 62% for stage III, and 31% for stage IV. Stage IV patients with no evidence of hematogenous metastasis could be candidates for radical therapy. Local recurrence was observed in 13% of stage II and III patients, attributed to inadequate intracavitary treatment and the histological diagnosis of adenocarcinoma. Severe complications occurred in only 12 (4%) of the 298 patients treated with irradiation alone. The relative 5-year survival rates for patients treated with post-operative irradiation were 91% for patients treated prophylactically and 49% for patients treated for residual tumor. Patients treated with post-operative irradiation for residual tumor at the resected end of the vagina showed a high cumulative survival rate of 77%. Since urinary sequelae developed in only 4 patients, it would seem that electron beam irradiation of the resected end of the vagina is a safe and effective method of therapy. (author)

    Only 8 cases of spontaneous uterine rupture in untreated cervical cancer have been reported in the literature. We present the case of a 52-year-old female, who was admitted to the emergency room due to hypovolemic shock and signs of peritonitis. A 6x4x4 cm cervical tumor was detected at physical exam. At laparotomy 2000 mL of purulent material were found and a 1-cm perforation in the posterior portion of the uterine segment was identified. A subtotal hysterectomy was performed. The patient received antibiotic and support at Intensive Care Unit. Finally, the patient presented ascendant flaccid paralysis and died due to bronchoaspiration. Spontaneous pyometra rupture in untreated cervical cancer is a rare condition and must be considered in postmenopausal women with cervical tumors and peritonitis signs.

    Full Text Available Robyn Banerjee,1 Mitchell Kamrava21Department of Radiation Oncology, Tom Baker Cancer Centre, Calgary, Alberta, Canada; 2Department of Radiation Oncology, University of California Los Angeles, Los Angeles, CA, USAAbstract: Dramatic advances have been made in brachytherapy for cervical cancer. Radiation treatment planning has evolved from two-dimensional to three-dimensional, incorporating magnetic resonance imaging and/or computed tomography into the treatment paradigm. This allows for better delineation and coverage of the tumor, as well as improved avoidance of surrounding organs. Consequently, advanced brachytherapy can achieve very high rates of local control with a reduction in morbidity, compared with historic approaches. This review provides an overview of state-of-the-art gynecologic brachytherapy, with a focus on recent advances and their implications for women with cervical cancer.Keywords: cervical cancer, brachytherapy, image-guided brachytherapy

    Expansive extirpation of the uterus was performed in 726 cases of stage TIbNXMO cervical cancer. 19.3% of 600 cases of pTIb cancer showed metastatic involvement of lymph nodes. Metastases into regional lymph nodes were found to be resistant to preoperative large-fraction irradiation. The long-term results of treatment of 484 patients with pTIbNOMO cervical cancer receiving 3 different treatment modalities (operation alone, surgery+preoperative irradiation and surgery+postoperative distant irradiation) did not show any significant difference. Complications and relapse were rarer in patients who received surgery only. Therefore, expansive extirpation of the uterus unaccompanied by distant radiotherapy should be a Method of choice in treatment of stage I cervical cancer (pTIbNOMO)

    Cancer is one of the contagious diseases that become a public health issue, both in the world and in Indonesia. In the world, 12% of all deaths caused by cancer and is the second killer after cardiovascular disease. Early detection using the IVA is a practical and inexpensive (only requiring acetic acid). However, the accuracy of the method is quite low, as it can not detect the stage of the cancer. While other methods have a better sensitivity than the IVA method, is a method of PAP smear. However, this method is relatively expensive, and requires an experienced pathologist-cytologist. According to the case above, Considered important to make the cancer cervics detector that is used to detect the abnormality and cervical cancer stage and consists of a digital microscope, as well as a computer application based on artificial neural network.

    Full Text Available Arsenic in drinking water is causally linked with cancer of the skin, lung, and urinary bladder, but there is very little data on a possible role for arsenic in the etiology of cervical cancer, a disease in which human papilloma virus is held to be a necessary but not sufficient cause. All histopathology results from cervical specimens from the National Institute of Cancer Research and Hospital (NICRH, Dhaka (1997–2015, and the Anowara Medical Services (2003–2015, both serving the whole of Bangladesh, were classified by cell type. Arsenic concentrations in well water in the thana of residence were estimated from systematic sampling carried out by the British Geological Survey. In a case-referent analysis arsenic estimates for cases of cervical cancer were compared with those found to have benign lesions. In this study, 3464 NICRH (CH cervical specimens and 30,050 community medical service (CMS specimens were available: 3329 (CH and 899 (CMS were recorded as malignant. Most were squamous cell carcinoma, of which 4.9% were poorly differentiated. Overall, there was no increase in cervical cancer with increasing arsenic concentration. Among those with squamous cell histology, a strong dose response was seen for poorly differentiated cancer with increasing arsenic exposure. The odds ratio increased monotonically, compared with exposure <10 μg/L, from 1.58 at 10 < 50 μg/L to 8.11 at >200 μg/L (p < 0.001. Given the high proportion of Bangladeshis using drinking water containing >50 μg/L of arsenic, the evidence that arsenic is implicated in cancer grade suggests a need for further investigation and the introduction of cervical screening in high arsenic areas.

    In the present pilot study, the feasibility of a site-of-care cervicovaginal self-sampling methodology for HPV-based screening was tested in 346 women residing in underserved rural areas of Northern Greece. These women provided self-collected cervicovaginal sample along with a study questionnaire. Following molecular testing, using the cobas ® HPV Test, Roche ® , HPV positive women, were referred to colposcopy and upon abnormal findings, to biopsy and treatment. Participation rate was 100%. Regular pap-test examination was reported for 17.1%. Among hrHPV testing, 11.9% were positive and colposcopy/biopsy revealed 2 CIN3 cases. Non-compliance was the most prevalent reason for no previous attendance. Most women reported non-difficulty and non-discomfort in self-sampling (77.6% and 82.4%, respectively). They would choose self-sampling over clinician-sampling (86.2%), and should self-sampling being available, they would test themselves more regularly (92.3%). In conclusion, self-sampling is feasible and well-accepted for HPV-based screening, and could increase population coverage in underserved areas, helping towards successful prevention.

  8. Epigenetic Silencing of CXCR4 Promotes Loss of Cell Adhesion in Cervical Cancer

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available In the network of chemokine signaling pathways, recent reports have described the SDF-1α/CXCR4 axis and its role in cancer progression and metastasis. Interestingly, we found downregulation of CXCR4 at both transcript and protein level in cervical cancer cell lines and primary tumors. We also found CXCR4 promoter hypermethylation in cervical cancer cell lines and primary biopsy samples. DNA hypomethylating drug 5-AZA-2′-deoxycytidine and histone deacetylase inhibitor Trichostatin A treatments in cell lines reactivate both CXCR4 transcription and protein expression. Cell adhesion assay demonstrated that autocrine SDF-1α promotes the loss of cell adhesion while paracrine SDF-1α predominantly protects the normal cervical cells from loss of cell adhesion. Cervical cancer cell line C-33A having increased expression of CXCR4 after TSA treatment showed increased cell adhesion by paracrine source of SDF-1α in comparison to untreated C-33A. These findings demonstrate the first evidence that epigenetic silencing of CXCR4 makes the cells inefficient to respond to the paracrine source of SDF-1α leading to loss of cell adhesion, one of the key events in metastases and progression of the disease. Our results provide novel insight of SDF-1α/CXCR4 signaling in tumor microenvironment which may be promising to further delineate molecular mechanism of cervical carcinogenesis.

    Cervical cancer is a malignancy originating in the transformation zone of the cervix, most commonly in the squamous cells. It is the fourth most common cancer in women worldwide, and the third most common cause of female cancer death. Genital human papilloma viruses (HPV) are sexually transmitted and approximately 630 milion people worldwide are infected. More than 200 genotypes, subtypes and variants have been reported, 13-15 being oncogenic type, which could be responsible for cervical intraepithelial lesions (CIN) or cancer. Aim of this study was to evaluate the prevalence of this infection and to identify specific types of human papiloma virus in cervical intraepithelial lesions and cervical cancer in Macedonian women. The study was conducted at the University Clinic for Obstetrics and Gynecology, Skopje, Macedonia, in a period of four years. The study was performed on a cohort of 1895, 18 - 73 year old patients who during primary examination had already abnormal PAP smear test. Cervical cells were collected in the lithotomy gynecological position of the patient, using endocervical cytobrush and cotton-tipped swab, and both were placed in sterile test tube with phosphate buffered saline. Samples were stored at temperature of 2 - 8 °C and Human Pappiloma Virus (HPV) genotyping was analyzed within 7 days by multiple Polymerase Chain Reaction (PCR) methods. The mean age of enrolled women was 40,8 years±10.36 SD(minimum of 18 and maximum 73 years. Among the patients, the presence of HPV by using PCR was detected in 40,68 % (769 patients) and was highly associated with cervical abnormalities. The prevalence of HPV was highest (82,1%) in women aged 20-years or less and it decreased with age and was lowest (19,9%) among patients older than 50 years. The prevalence of oncogenic types of the virus was higher if the cytologic diagnosis is CIN 3/Carcinoma in situ (CIS). In these patients detection of high risk HPV was in 79,1% females with CIN 3 and 97,5 % in females

    Full Text Available Abstract Background In a recent pilot report, we showed that Smac/DIABLO mRNA is expressed de novo in a subset of cervical cancer patients. We have now expanded this study and analyzed Smac/DIABLO expression in the primary lesions in 109 cervical cancer patients. Methods We used immunohistochemistry of formalin-fixed, paraffin-embedded tissue sections to analyze Smac/DIABLO expression in the 109 primary lesions. Seventy-eight samples corresponded to epidermoid cervical cancer and 31 to cervical adenocarcinoma. The median follow up was 46.86 months (range 10–186. Results Smac/DIABLO was expressed in more adenocarcinoma samples than squamous tumours (71% vs 50%; p = 0.037. Among the pathological variables, a positive correlation was found between Smac/DIABLO immunoreactivity and microvascular density, a marker for angiogenesis (p = 0.04. Most importantly, Smac/DIABLO immunoreactivity was associated with a higher rate of local recurrence in squamous cell carcinoma (p = 0.002, log rank test. No association was found between Smac/DIABLO and survival rates. Conclusion Smac/DIABLO expression is a potential marker for local recurrence in cervical squamous cell carcinoma patients.

We have now expanded this study and analyzed Smac/DIABLO expression in the primary lesions in 109 cervical cancer patients. We used immunohistochemistry of formalin-fixed, paraffin-embedded tissue sections to analyze Smac/DIABLO expression in the 109 primary lesions. Seventy-eight samples corresponded to epidermoid cervical cancer and 31 to cervical adenocarcinoma. The median follow up was 46.86 months (range 10–186). Smac/DIABLO was expressed in more adenocarcinoma samples than squamous tumours (71% vs 50%; p = 0.037). Among the pathological variables, a positive correlation was found between Smac/DIABLO immunoreactivity and microvascular density, a marker for angiogenesis (p = 0.04). Most importantly, Smac/DIABLO immunoreactivity was associated with a higher rate of local recurrence in squamous cell carcinoma (p = 0.002, log rank test). No association was found between Smac/DIABLO and survival rates. Smac/DIABLO expression is a potential marker for local recurrence in cervical squamous cell carcinoma patients

    Chromatin in cervical cancer (CC) undergoes chemical and structural changes that alter the expression pattern of genes. Recently, a potential mechanism, which regulates gene expression at transcriptional levels is the proteolytic clipping of histone H3. However, until now this process in CC has not been reported. Using HeLa cells as a model of CC and human samples from patients with CC, we identify that the H3 cleavage was lower in CC compared with control tissue. Additionally, the histone H3 clipping was performed by serine and aspartyl proteases in HeLa cells. These results suggest that histone H3 clipping operates as part of post-translational modification system in CC. PMID:27698925

    Full Text Available Aberrant DNA methylation has been observed in cervical cancer; however, most studies have used non-quantitative approaches to measure DNA methylation. The objective of this study was to quantify methylation within a select panel of genes previously identified as targets for epigenetic silencing in cervical cancer and to identify genes with elevated methylation that can distinguish cancer from normal cervical tissues. We identified 49 women with invasive squamous cell cancer of the cervix and 22 women with normal cytology specimens. Bisulfite-modified genomic DNA was amplified and quantitative pyrosequencing completed for 10 genes (APC, CCNA, CDH1, CDH13, WIF1, TIMP3, DAPK1, RARB, FHIT, and SLIT2. A Methylation Index was calculated as the mean percent methylation across all CpG sites analyzed per gene (~4-9 CpG site per sequence. A binary cut-point was defined at >15% methylation. Sensitivity, specificity and area under ROC curve (AUC of methylation in individual genes or a panel was examined. The median methylation index was significantly higher in cases compared to controls in 8 genes, whereas there was no difference in median methylation for 2 genes. Compared to HPV and age, the combination of DNA methylation level of DAPK1, SLIT2, WIF1 and RARB with HPV and age significantly improved the AUC from 0.79 to 0.99 (95% CI: 0.97-1.00, p-value = 0.003. Pyrosequencing analysis confirmed that several genes are common targets for aberrant methylation in cervical cancer and DNA methylation level of four genes appears to increase specificity to identify cancer compared to HPV detection alone. Alterations in DNA methylation of specific genes in cervical cancers, such as DAPK1, RARB, WIF1, and SLIT2, may also occur early in cervical carcinogenesis and should be evaluated.

    Human papillomavirus (HPV) infection has been firmly established as a central and necessary cause of invasive cervical cancer and it has been etiologically linked to other anogenital (vulva, vagina, anus and penis) and head and neck cancers, particularly oropharyngeal. Although being rare, the incidence of some of these cancers in some countries has increased in the last decades. HPV-related anogenital tumors share many risk factors with cervical cancer. The HPV aetiological contribution differs in each anatomical location reflecting differences in the natural history and viral tissue tropism. The highest prevalence of HPV DNA in cancers other than cervix has been described for anal, followed by vagina, penile and vulvar cancers. HPV16 has been described as the most common type detected in all cancer sites with different contributions being the highest in anal carcinoma (around 80% of HPV DNA positive anal cancers) and the lowest in vaginal cancers with a contribution similar to that found in cervical cancers (around 60%). Current HPV vaccines have already demonstrated their efficacy in preventing anogenital pre-neoplastic lesions caused by vaccine HPV types. HPV-based prevention tools like HPV vaccination and to a lesser extend screening (e.g. for anal cancer) can be useful measures for reducing the burden of these anogenital cancers.

    Objectives Cervical cancer is the leading cause of cancer deaths among women in Haiti. Given this high disease burden, we sought to better understand women’s knowledge of its causes and the socio-demographic and health correlates of cervical cancer screening. Methods Participants were 410 adult women presenting at clinics in Léogâne and Port-au-Prince, Haiti. We used bivariate and multivariate logic regression to identify correlates of Pap smear receipt. Results Only 29% of respondents had heard of human papillomavirus (HPV), while 98% were aware of cervical cancer. Of those aware of cervical cancer, 12% believed sexually transmitted infections (STIs) cause it, and only 4% identified HPV infection as the cause. Women with a previous STI were more likely to have had Pap smear (34% vs. 71%, OR=3.45; 95% CI: 1.57–7.59). Screening was also more likely among women who were older than age 39, better educated and employed (all p<.05). Almost all women (97%) were willing to undergo cervical cancer screening. Conclusions This sample of Haitian women had limited awareness of HPV and cervical cancer causes; but when provided with health information, they saw the benefits of cancer screening. Future initiatives should provide health education messages, with efforts targeting young and at-risk women. PMID:27906806

    Full Text Available AIM: Cervical cancer is the most frequently seen genital system cancer in women after endometrium adenocarcinoma. Because cervical is an easy reach organ, early diagnosis can be done due to Papanicolau (Pap smear in the cancer cases of this organ and prognosis ameliorates considerably. In this ailment there are two peaks. The first one is around the ages 35-39, the second one is around the ages 60-64. The aim of the study is to scan cervical cancer among the women between the ages of 35-40 in the district of Kisecik health office. METHOD: This study is a definitional, society based sectional study performed among the women between the ages of 35- 40 in the district of Kisecik in Hatay. 187 women between the ages of 35- 40 were enrolled to the study; 10 out of 187 women who were single were not included to the study. The study was completed after enrolling 150 women out of 177. Cervical smear samples were taken from the participants; and these samples were evaluated in a pathology laboratory according to the Bethesda 2001 scale. RESULTS: The avarage age of the participants was 37.55±1.77. After the evaluation of the cervical smears in the pathology laboratory, the results were normal for 73 participants (%48.7. 36 participants (%24.0 had non specific inflamation, 20 participants (%13.3 had bacterial vaginosis, 19 participants (%12.7 had seconder reactive changes to the inflamation and 2 participants (%1.3 was reported to be ASC-US. CONCLUSION: By the help of cheap and easily applied Pap smear test, society based scanning programmes can be performed frequently and thus; servical lesions may be detected in early phases. Furthermore through education, the level of information about cervical cancer should be raised and consciousness should be created. [TAF Prev Med Bull 2010; 9(5.000: 471-474

    Cervical cancer is a predominantly human papillomavirus (HPV)-driven disease worldwide. However, its incidence is unexplainably low in western Asia, including Saudi Arabia. Using this paradigm, we investigated the role of HPV infection rate and host genetic predisposition in TP53 G72C single nucleotide polymorphism (SNP) presumed to affect cancer incidence. Patients treated between 1990 and 2012 were reviewed, and a series of 232 invasive cervical cancer cases were studied and compared with 313 matched controls without cancer. SNP was genotyped by way of direct sequencing. HPV linear array analysis was used to detect and genotype HPV in tumor samples. The incidence of cervical cancer revealed bimodal peaks at 42.5 years, with a slighter rebound at 60.8 years. Among all cases, 77% were HPV-positive and 16 HPV genotypes were detected-mostly genotypes 16 (75%) and 18 (9%)-with no difference by age, histology, or geographical region. Although the TP53 G72C genotype was not associated with overall cervical cancer risk, it was significantly associated with HPV positivity (odds ratio, 0.57; 95% confidence interval, 0.36-0.90; P = .016). Furthermore, the variant C allele was significantly overtransmitted in the population (P Cervical cancer incidence displays bimodal curve peaking at a young age with secondary rebound at older age. The combination of relative low HPV infection and variant TP53 72C allele overtransmission provide a plausible explanation for the low incidence of cervical cancer in our population. Therefore, HPV screening and host SNP genotyping may provide more relevant biomarkers to gauge the risk of developing cervical cancer.

    Full Text Available The study aimed to investigate the state of human papillomavirus (HPV infection in patients with cervical cancer in the Uyghur population in China and to identify miRNA as biomarker for cervical cancer and HPV infection. We also performed genotyping to determine the variation in the types of HPV. Using microRNA (miRNA microarray technology, differential miRNA expression between HPV-infected cervical cancer and uninfected normal cervical tissues was determined; the microarray results were verified by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR using 20 samples of both the tissues. The infection rate of HPV in patients with cervical cancer was 96.7% (29 of 30, and the main subtype identified was HPV16 (29 of 29. HPV16 integration assay demonstrated that the majority of infectious cases were of the integrated form (26 of 29. Analysis of 140 miRNAs demonstrated greater than two-fold change in miRNA expression in HPV-infected cervical cancer tissue as compared to that in uninfected cervical tissue. The qRT-PCR analysis verified that the expression of miR-15a-5p, miR-17-5p, miR-20a-5p, miR-21-5p, miR-96, miR-106b-5p, and miR-3653 was higher, while the expression of miR-497-5p was lower in cancer tissues than in normal tissues. The results demonstrate significant changes in miRNA expression in cervical cancer tissues associated with HPV infection as compared to that in normal tissues. These molecular markers may be useful for an early diagnosis and prognosis of cervical cancer in specific human populations.

    Human papillomavirus (HPV), especially HPV 16, is associated with the development of both cervical and oral cancer. We show the case of a woman affected by HPV-related cervical disease and oropharyngeal squamous cell carcinoma (OPSCC). A 41-year-old woman arrived at our Colposcopy Center following an abnormal Pap smear result (ASC-H) and a diagnosis of moderate cervical dysplasia obtained by a cervical biopsy. She underwent a colposcopy that showed a cervical abnormal transformation zone grade 2. A laser conization was performed in November 2010. Histology reported a moderate/severe dysplasia. The cone resection margins were free. Follow-up colposcopy and cytology were negative. The HPV testing showed an infection by HPV 16. In October 2012, the patient presented to the Head-Neck ER after episodes of hemoptysis; a lesion was found in the left tonsillar lodge. A biopsy was performed with a result of squamous cell carcinoma with low-grade differentiation. The HPV testing detected a high-risk HPV and the immunohistochemical analysis was positive for p16. She was treated by chemotherapy and brachytherapy. She was followed at the head-neck center with monthly visits with oral visual inspection that showed complete absence of mucosal abnormalities. HPV-related OPSCC and cervical precancerous/cancerous lesions have significant similarities in terms of pathogenesis. They are both caused largely by HPV 16, as in the present case. In conclusion, because of this association found in literature and in our case, we think that women with HPV cervical lesions should have regular surveillance for oropharyngeal cancer, whereas women with OPSCC should be encouraged to have diligent cervical screening.

Early screening for cervical cancer is a key intervention in reduction of maternal deaths. Health care workers have a significant contribution to improve cervical cancer screening practice among women. Hence, this study aimed to assess the knowledge and practice of cervical cancer screening among female health care workers in southern Ethiopia.Methods: Institution-based cross-sectional study was conducted during March and April, 2015. All hospitals in Hawassa city administration and Sidama zone were purposively selected. A simple random sampling technique was used to draw the health centers. After proportional allocations to their respective health facilities, a total of 367 female health workers were selected by simple random sampling technique. A structured and pretested questionnaire was used to collect the data. Data were entered to SPSS version 20.0 for further analysis. Logistic regression analyses were used to see the association of different variables.Results: Out of the total respondents, 319 (86.9% had a good level of knowledge on cervical cancer. Similarly, a majority of them, 329 (89.6%, 321 (87.5%, and 295 (80.4%, knew about the risk factors, symptoms, and outcomes of cervical cancer, respectively. More than two thirds of the respondents, 283 (77.1%, knew that there is a procedure used to detect premalignant cervical lesions and 138 (37.6% of them mentioned visual inspection with acetic acid as a screening method.

    To assess the knowledge of young female Singaporeans regarding cervical cancer and pap smear, the intention to participate in pap smear and whether there is any relationship between knowledge and intention to participate in pap smear screening. While cervical cancer has poor prognosis in the later stages, pap smear is effective in identifying precancerous lesions, which are more treatable. Pap smear screening is available to women in Singapore, but its uptake is opportunistic. Research has shown that knowledge about pap smear and cervical cancer is important determinant of screening behaviour in Singaporean women. Cross-sectional descriptive correlational design was used. Three hundred and ninety-three young Singaporean undergraduates, aged 18-25 years, were recruited via convenience sampling from a local university over a four-month period. Data were collected through self-administered questionnaires. Majority of the participants knew the term 'pap smear' and its function. However, knowledge of the risk factors for cervical cancer was lacking among the young women. Knowledge of pap smear and cervical cancer had a weak correlation with the intention to go for the future uptake of pap smear. Educational efforts among younger Singaporean women on the knowledge of pap smear and risk factors for cervical cancer are needed. Improving knowledge will enable them to understand the importance of reducing exposure to risk factors and regular pap smear screening. All health professionals working with young Asian women should be prepared to educate and counsel young women to participate in pap smear screening according to current guidelines. In particular, knowledge of the age to attend the first pap smear and the recommended frequency for screening need to be targeted for health education. © 2013 John Wiley & Sons Ltd.

    Full Text Available The central phenomenon of interest to the authors was the experiences of Batswana women who have been diagnosed with both HIV/AIDS and cervical cancer. They wanted to know how these women and their families coped with the burden of the two ‘fatal’ diseases. This interest was brought about by the current surge in cervical cancer cases in the country, and the relationship between the two diseases. There is scant literature on the experiences of women with the dual diagnosis of HIV/AIDS and cervical cancer. The purpose of the study was to explore the experiences of Batswana women who are diagnosed with both HIV/AIDS and cervical cancer. The research question was ‘What are the experiences of Batswana women diagnosed with both HIV/AIDS and cervical cancer?’ A phenomenological descriptive qualitative research design was therefore appropriate to answer the research question. Semi-structured interviews and field notes were used to collect data. One-to-one interviews were conducted with six women diagnosed with the two diseases. Both convenience and purposive sampling techniques were used in selection of participants. The seven procedural steps proposed by Collaizi (1978 were utilized in data analysis as the study was based on the phenomenology approach. The findings revealed that HIV/AIDS and cervical cancer are chronic illnesses that can instill chronic emotional pain. Reactions to diagnosis with these diseases include pain, fear or intense sadness. Coping with these conditions can be facilitated by different strategies such as acceptance, having hope, support from others and positive thinking. Support can come from children, family members, informal or formal groups and health service providers.

    Cervical cancer is recognized as tobacco-related malignancy. HPV vaccination and introducing screening protocols were found as the best way to decrease cervical cancer related mortality. Besides the cytological screening programs of the uterine cervix smear, nowadays co-factors of carcinogenesis are taken into consideration, also. The aim of our study was to analyse data included in questionnaire of 310 women who underwent cytological examination wi thin cervical cancer screening program in our Department in 2011. There were no differences found between studied groups on rate of oral contraceptive or hormonal therapy use, as well as age and tobacco smoking. However, taking into account education and smoking, there was a significant correlation observed. Patients with higher education level smoked less often. The special attention should be paid to promote smoking cessation in the group of women who finished education on elementary level.

    Recently, attempts have made to use radiotherapy in combination with chemotherapy in various solid tumors including cervical cancer. Twenty-four patients with locally advanced cervical cancer were treated with concurrent Carboplatin (16-24 mg/m 2 /day) or Nedaplatin (20 mg/m 2 /week) and conventional radiotherapy. Of 13 evaluable patients, there were nine complete responders and four partial responders. There was no renal damage or grade 4 hematological toxicity. Gastrointestinal adverse reactions were mild. One patient had grade 3 dermatologic toxicity after delayed radiation therapy. This pilot study suggests that daily Carboplatin or weekly Nedaplatin administered with standard radiation therapy is safe, well-tolerated, and thus may be useful as a radiation sensitizer in the treatment of locally advanced cervical cancer.

    Every year, cervical cancer affects ∼500,000 women worldwide, and ∼275,000 patients die of this disease. The addition of platin-based chemotherapy to primary radiotherapy has increased 5-year survival of advanced-stage cervical cancer patients, which is, however, still only 66%. One of the factors thought to contribute to treatment failure is the ability of tumor cells to repair chemoradiotherapy-induced DNA damage. Therefore, sensitization of tumor cells for chemoradiotherapy via inhibition of the DNA damage response (DDR) as a novel strategy to improve therapy effect, is currently studied pre-clinically as well as in the clinic. Almost invariably, cervical carcinogenesis involves infection with the human papillomavirus (HPV), which inactivates part of the DNA damage response. This HPV-mediated partial inactivation of the DDR presents therapeutic targeting of the residual DDR as an interesting approach to achieve chemoradio-sensitization for cervical cancer. How the DDR can be most efficiently targeted, however, remains unclear. The fact that cisplatin and radiotherapy activate multiple signaling axes within the DDR further complicates a rational choice of therapeutic targets within the DDR. In this review, we provide an overview of the current preclinical and clinical knowledge about targeting the DDR in cervical cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

  19. The Epidemiology of Human Papillomavirus Infection and Cervical Cancer

    Full Text Available Cervical cancer has been recognized as a rare outcome of a common Sexually Transmitted Infection (STI. The etiologic association is restricted to a limited number of viral types of the family of the Human Papillomaviruses (HPVs. The association is causal in nature and under optimal testing systems, HPV DNA can be identified in all specimens of invasive cervical cancer. As a consequence, it has been claimed that HPV infection is a necessary cause of cervical cancer. The evidence is consistent worldwide and implies both the Squamous Cell Carcinomas (SCC, the adenocarcinomas and the vast majority (i.e. > 95% of the immediate precursors, namely High Grade Squamous Intraepithelial Lesions (HSIL/Cervical Intraepithelial Neoplasia 3 (CIN3/Carcinoma in situ. Co-factors that modify the risk among HPV DNA positive women include the use of oral contraceptives (OC for five or more years, smoking, high parity (five or more full term pregnancies and previous exposure to other sexually transmitted diseases such as Chlamydia Trachomatis (CT and Herpes Simplex Virus type 2 (HSV-2. Women exposed to the Human Immunodeficiency Virus (HIV are at high risk for HPV infection, HPV DNA persistency and progression of HPV lesions to cervical cancer.

    Full Text Available Abstract Background To provide quantitative insight into current U.S. policy choices for cervical cancer prevention, we developed a model of human papillomavirus (HPV and cervical cancer, explicitly incorporating uncertainty about the natural history of disease. Methods We developed a stochastic microsimulation of cervical cancer that distinguishes different HPV types by their incidence, clearance, persistence, and progression. Input parameter sets were sampled randomly from uniform distributions, and simulations undertaken with each set. Through systematic reviews and formal data synthesis, we established multiple epidemiologic targets for model calibration, including age-specific prevalence of HPV by type, age-specific prevalence of cervical intraepithelial neoplasia (CIN, HPV type distribution within CIN and cancer, and age-specific cancer incidence. For each set of sampled input parameters, likelihood-based goodness-of-fit (GOF scores were computed based on comparisons between model-predicted outcomes and calibration targets. Using 50 randomly resampled, good-fitting parameter sets, we assessed the external consistency and face validity of the model, comparing predicted screening outcomes to independent data. To illustrate the advantage of this approach in reflecting parameter uncertainty, we used the 50 sets to project the distribution of health outcomes in U.S. women under different cervical cancer prevention strategies. Results Approximately 200 good-fitting parameter sets were identified from 1,000,000 simulated sets. Modeled screening outcomes were externally consistent with results from multiple independent data sources. Based on 50 good-fitting parameter sets, the expected reductions in lifetime risk of cancer with annual or biennial screening were 76% (range across 50 sets: 69–82% and 69% (60–77%, respectively. The reduction from vaccination alone was 75%, although it ranged from 60% to 88%, reflecting considerable parameter

    The aim of this narrative review is to update the current knowledge on the treatment of recurrent cervical cancer based on a literature review. A web based search in Medline and CancerLit databases has been carried out on recurrent cervical cancer management and treatment. All relevant information has been collected and analyzed, prioritizing randomized clinical trials. Cervical cancer still represents a significant problem for public health with an annual incidence of about half a million new cases worldwide. Percentages of pelvic recurrences fluctuate from 10% to 74% depending on different risk factors. Accordingly to the literature, it is suggested that chemoradiation treatment (containing cisplatin and/or taxanes) could represent the treatment of choice for locoregional recurrences of cervical cancer after radical surgery. Pelvic exenteration is usually indicated for selected cases of central recurrence of cervical cancer after primary or adjuvant radiation and chemotherapy with bladder and/or rectum infiltration neither extended to the pelvic side walls nor showing any signs of extrapelvic spread of disease. Laterally extended endopelvic resection (LEER) for the treatment of those patients with a locally advanced disease or with a recurrence affecting the pelvic wall has been described. The treatment of recurrences of cervical carcinoma consists of surgery, and of radiation and chemotherapy, or the combination of different modalities taking into consideration the type of primary therapy, the site of recurrence, the disease-free interval, the patient symptoms, performance status, and the degree to which any given treatment might be beneficial.

    Context and objective Incarcerated women are more vulnerable to developing cervical cancer than women in general; therefore, screening and intervention programs must be included in their healthcare provision. We therefore aimed to investigate the state of cervical cancer screening for imprisoned women in Mato Grosso do Sul, and to analyze the interventions geared toward the control of cervical cancer. Materials and methods This was a cross-sectional study with analysis of primary and secondary data. Interviews were held with 510 women in seven prisons in the Brazilian state of Mato Grosso do Sul. The data for 352 medical records were analyzed statistically with the significance level set at 5%. Associations were assessed by the chi-squared test, adjusted by the Bonferroni correction. Results Most female prisoners had limited education, used tobacco, and had key risk factors for the development of cervical cancer. Half of the women interviewed (n = 255) stated that they had received a Papanicolaou (Pap) test in prison, but 134 (52.5%) of these did not know the result. Of those who had not received a Pap test, 149 (58.4%) stated that this was because of a lack of opportunity. There was no information regarding the provision of Pap tests or subsequent treatment in the medical records of 211 (59.9%) women. No protocols were in place for the provision of Pap tests in prison. There were statistical differences between prisons in terms of test frequency, the information provided to women, and how information was recorded in medical records. Conclusion The screening of cervical cancer in prisons is neither systematic nor regular, and the results are not communicated to women in a significant number of cases. It is necessary to organize health services within the prison environment, ensuring that tests are done and that there is investigation for human papillomavirus. This could increase the diagnosis of cervical cancer at less advanced stages of the disease. PMID:29252994

    Telomeres are transcribed into long non-coding RNA, referred to as telomeric repeat-containing RNA (TERRA), which plays important roles in maintaining telomere integrity and heterochromatin formation. TERRA has been well characterized in HeLa cells, a type of cervical cancer cell. However, TERRA abundance and stability have not been examined in other cervical cancer cells, at least to the best of our knowledge. Thus, in this study, we measured TERRA levels and stability, as well as telomere length in 6 cervical cancer cell lines, HeLa, SiHa, CaSki, HeLa S3, C-33A and SNU-17. We also examined the association between the TERRA level and its stability and telomere length. We found that the TERRA level was several fold greater in the SiHa, CaSki, HeLa S3, C-33A and SNU-17 cells, than in the HeLa cells. An RNA stability assay of actinomycin D-treated cells revealed that TERRA had a short half-life of ~4 h in HeLa cells, which was consistent with previous studies, but was more stable with a longer half-life (>8 h) in the other 5 cell lines. Telomere length varied from 4 to 9 kb in the cells and did not correlate significantly with the TERRA level. On the whole, our data indicate that TERRA abundance and stability vary between different types of cervical cancer cells. TERRA degrades rapidly in HeLa cells, but is maintained stably in other cervical cancer cells that accumulate higher levels of TERRA. TERRA abundance is associated with the stability of RNA in cervical cancer cells, but is unlikely associated with telomere length.

    The aim of the present study was to determine the preliminary mechanism of action of B7 homolog 1 (B7-H1) and investigate the association between B7-H1 and cervical cancer. The expression of B7 family proteins was measured in cervical cancer cells. Cervical cancer cells were co-cultured with T lymphocytes. An ELISA assay was subsequently conducted to analyze cytokine concentrations in the supernatants of the cultured T cells in cervical cancer cells and B7-H1 downregulated cells. Levels of interleukin (IL)-1β, IL-6 and tumor necrosis factor-α mRNA in mice injected with cervical cancer cells or B7-H1 downregulated cells were measured by reverse transcription-quantitative polymerase chain reaction. It was determined that cervical cancer cells express high levels of B7-H1, whereas the normal cervical epithelium does not express B7-H1. When co-cultured with T lymphocytes, cervical cancer cells were involved in the inhibition of lymphocyte activation. When B7-H1 was downregulated using a lentivirus, the proliferation ability did not change compared with cervical cancer cells, whereas the soluble factors secreted by T cells differed between cervical cancer cells and B7-H1 downregulated cells. In an animal model, injected B7-H1 downregulated cervical cancer cells elicited a more intense immune response, whereas cervical cancer cells had the wild immune response. Therefore, the results of the present study demonstrate that B7-H1 mediates the low immunogenicity of cervical cancer and is not attacked by the immune system.

    Circulating tumor cells (CTC) are newly discovered biomarkers of cancers. Although many systems detect CTC, a gold standard has not yet been established. We analyzed CTC in uterine cervical cancer patients using an advanced version of conditionally replicative adenovirus targeting telomerase-positive cells, which was enabled to infect coxsackievirus-adenovirus receptor-negative cells and to reduce false-positive signals in myeloid cells. Blood samples from cervical cancer patients were hemolyzed and infected with the virus and then labeled with fluorescent anti-CD45 and anti-pan cytokeratin antibodies. GFP (+)/CD45 (-) cells were isolated and subjected to whole-genome amplification followed by polymerase chain reaction analysis of human papillomavirus (HPV) DNA. CTC were detected in 6 of 23 patients with cervical cancers (26.0%). Expression of CTC did not correlate with the stage of cancer or other clinicopathological factors. In 5 of the 6 CTC-positive cases, the same subtype of HPV DNA as that of the corresponding primary lesion was detected, indicating that the CTC originated from HPV-infected cancer cells. These CTC were all negative for cytokeratins. The CTC detected by our system were genetically confirmed. CTC derived from uterine cervical cancers had lost epithelial characteristics, indicating that epithelial marker-dependent systems do not have the capacity to detect these cells in cervical cancer patients. © 2017 The Authors.

    2014-01-01

    Dramatic advances have been made in brachytherapy for cervical cancer. Radiation treatment planning has evolved from two-dimensional to three-dimensional, incorporating magnetic resonance imaging and/or computed tomography into the treatment paradigm. This allows for better delineation and coverage of the tumor, as well as improved avoidance of surrounding organs. Consequently, advanced brachytherapy can achieve very high rates of local control with a reduction in morbidity, compared with historic approaches. This review provides an overview of state-of-the-art gynecologic brachytherapy, with a focus on recent advances and their implications for women with cervical cancer.

    Full Text Available A new technique of extensive surgical intervention, namely nerve sparing radical hysterectomy (NSRH, was introduced as one of the treatment options for early stage cervical cancer patients because cervical cancer patients suffer from postoperative complications following radical hysterectomy procedure. The step of nerve preservation can reduce postoperative complications, such as bladder or sexual dysfunction problems that occur after a traditional radical hysterectomy procedure. The surgical outcomes seem to be favorable and no serious morbidity was noted. However, further study of the nerve sparing technique is necessary to improve this surgical advantage in the future.

    HPV is the most common sexually transmitted infection in the world. While most strains are relatively harmless, some increase a woman's risk of developing cervical cancer. This article explores the intimate, contested relationships among etiologies of cervical cancer, development and use of the new HPV vaccine, and contested notions of sexuality. We particularly focus on shifts in US health care and sexual politics, where the vaccine has animated longstanding concerns about vaccination (e.g. parental rights, cost, specialisation) and young women's bodies and behaviour. We conclude that vaccines are a distinctive kind of pharmaceutical, invoking notions of contagion and containment, and that politics shape every aspect of the pharmaceutical life course.

    Full Text Available The high incidence of cervical cancer amongst South African black women is complicated by late presentation for treatment as well as by misconceptions and ignorance which adversely affect the quality of their lives. The aim of the research was to determine the disease-related needs of patients suffering from cervical cancer which would serve as a basis for planning on providing for these needs. Needs for the following were identified: • Education on early detection in the community. • Education on nutrition and hygiene. • Information on and assistance in obtaining financial relief by means of subsidised transport and disability pensions.

    RIP140 (Receptor Interacting Protein) is involved in the regulation of oncogenic signaling pathways and in the development of breast and colon cancers. The aim of the study was to analyze the expression of RIP140 and its partner LCoR in cervical cancers, to decipher their relationship with histone protein modifications and to identify a potential link with patient survival. Immunohistochemical analyses were carried out to quantify RIP140 and LCoR expression in formalin-fixed paraffin-embedded tissue sections cervical cancer samples. Correlations of RIP140 and LCoR expression with histopathological variables were determined by correlation analyses. Survival rates of patients expressing low or high levels of RIP140 and LCoR were compared by Kaplan-Meier curves. RIP140 overexpression was associated with a significantly shorter overall survival of cervical cancer patients. This effect was significant in the squamous cell carcinoma subtype but not in adenocarcinomas. RIP140 is no longer a significant negative prognosticator for cervical cancer when LCoR expression is low. RIP140 is an independent predictor of poor survival of patients with cervical cancer. Patients with tumors expressing low levels of both RIP140 and LCoR showed a better survival compared to patients expressing high levels of RIP140. Modulation of RIP140 and LCoR may represent a novel targeting strategy for cervical cancer prevention and therapy.

    Cervical cancer is the commonest cancer and the leading cause of cancer mortality in women in Gabon. The age-standardized incidence of cervical cancer is 19.9 per 100 000 women and the mortality rate is 8.4 per 100 000. Various international studies have identified the lack of awareness and knowledge about cervical cancer as barriers to use preventive methods. This article assesses the awareness and knowledge about cervical cancer, Pap smear testing and its use and HPV among women living in Libreville, Gabon. This study was conducted in October 2014 in Libreville. A total of 452 women aged 16 years and above were recruited from different town locations. Logistic regression analysis was used to identify the effect of demographic characteristics on the level of knowledge about cervical cancer, Pap smear testing and HPV. Odds ratio and 95% confidence intervals were used to identify the strength of association. Associations were considered statistically significant at p cervical cancer and only 27.9% (126/452) had heard of Pap smear test. Of these 126 women, only 65.1% (82/126) had done cervical cancer screening and 68.3% (56/82) on the suggestion of a doctor. The most common reason for not undergoing Pap smear testing was neglect (50%, 22/44) followed by lack of financial resources (13.6%, 6/44), fear of discovering a serious disease (13.6%, 6/44) and deeming it unimportant (13.6%, 6/44). Only 8% (40/452) of the participants had heard about HPV and their knowledge of HPV was fair. There is a very poor level of knowledge about cervical cancer among Gabonese women. This study demonstrates a very low level of knowledge about cervical cancer, Pap smear testing and HPV in a sample of Gabonese women. There is a critical need for Gabonese women to be informed about cervical cancer and the Pap smear test to improve the use of this preventive method. The implication of health staff and Gabonese media should be included as a centerpiece in the effort to inform the population in

    To investigate the expression of La protein in cervical cancer tissues and explore its role in the occurrence and progression of cervical cancer. The expression of La protein in cervical cancer and normal cervical tissues was detected by immunohistochemical staining. RNA interference technology was used to silence La protein expression in HeLa cells and the changes in cell proliferation, tumor sphere formation and cell cycles were investigated. The expression of La protein was significantly higher in cervical cancer tissues than in normal cervical tissues (61% vs 9%, PLa protein expression in HeLa cells caused significantly reduced the cell proliferation and lowered the tumor sphere formation rate from the control level of (17.1=1.92)% to (6.3=0.45)% (PLa can promote the development of cervical cancer and may play a critical role in the carcinogenesis and progression of cervical cancer.

    Recent policy revisions allow greater inclusion of military women in operational and/or deployable positions (ie, shipboard, overseas, and war zone duty assignments), but these positions can create unique health care challenges. Military members are often transient due to deployments and change of duty stations, impacting timely follow-up care for treatable health conditions. There has been minimal research on challenges or strategies in preventive health screening and follow-up for US military women. The purpose of this qualitative research study was to describe US Navy women's experiences with abnormal cervical cancer screenings requiring colposcopic follow-up care. Ship- and shored-based women receiving care at a military colposcopy clinic completed interviews about their experience. Two forms of narrative analysis, Labov's sociolinguistic structural analysis and Braun and Clarke's thematic analysis, were employed to gain a more robust understanding of the women's experiences. The sample was comprised of 26 women (16 ship-based, 10 shore-based). Five themes were identified: 1) It's like this bombshell (initial abnormal results notification); 2) I didn't understand (self-discovery process); 3) Freaked (emotional toll); 4) It's kind of like this back and forth (scheduling and navigating care); and 5) It really opened my eyes (lessons learned). The women's stories highlighted some issues unique to military health care, such as operational demands and follow-up care; other issues are likely common for most women learning about an abnormal cervical cancer screening result. Areas important for practice and future research include improving notification practices, providing information, understanding women's fear, and continuity of care. Research exploring educational initiatives and self-management practices are critical within military populations. © 2016 by the American College of Nurse-Midwives.

    Norway has a low incidence and mortality rate of cervical cancer, which is mainly due to the high participation rate of women in cervical cancer screening. However, the attendance of cervical cancer screening was reported to be low among immigrant women. For this reason, we conducted a qualitative study to obtain better insight into perceived barriers and challenges to cervical cancer screening among Somali and Pakistani women in the Oslo region. A convenient sample of 35 (18 Pakistani, 17 Somali) women were recruited for the study in collaboration with Somali and Pakistani community partners. Focus group discussions were used to explore barriers and facilitators to cervical cancer screening, whereas the Ecological Model was used as the framework for the study. The study found three levels of barriers to cervical cancer screening. The individual level included a lack of understanding of the benefits of the screening. The sociocultural level included the stigma attached to the disease and the belief that women who are unmarried are sexually inactive. The system-related level included a lack of trust toward the health care system. Based on the study results, and using a common denominator approach for the immigrant groups included, the study recommends three communication strategies with the potential to improve women's participation in cervical cancer screening: 1) in-person communication and information material at health centers; 2) verbal communication with women through seminars and workshops to educate them about their risk of cancer and the importance of screening and 3) the initiation of better recall through SMS and letters written in native languages. Finally, an intervention study that compares the aforementioned strategies and proves their effectiveness in increasing immigrant women's participation in cervical cancer screening is recommended.

    Full Text Available Prevention plays a central role in early detection of cervical cancer. Common Sense Model proposes that the nature and organization of illness representations can guide actions related to health and how self-care is exercised. The aim of this study was to describe and compare illness perception, knowledge and self-care in women with and without cancer precursor lesions. Participants were 92 women (aged 18-59 from primary care unity divided into two groups: women with and without premalignant lesion. Measures for illness perception, knowledge and self-care were used. There was no statistically significant difference (t test e chi-square test between groups in the variables analyzed. Despite the risk for cervical cancer, women with precursor lesions do not adjust their illness perceptions, knowledge and self-care to the situation. These data show the need to warn women against the cervical cancer risks, because their distorted perceptions and lack of knowledge about the disease may hamper the screening and control of cervical cancer.

    Cervical cancer is one of the most common female malignancies, and cisplatin-based chemotherapy is routinely utilized in locally advanced cervical cancer patients. However, resistance has been the major limitation. In this study, we found that Na+/H+ Exchanger Regulatory Factor 1 (NHERF1) was downregulated in cisplatin-resistant cells. Analysis based on a cervical cancer dataset from The Cancer Genome Atlas (TCGA) showed association of NHERF1 expression with disease-free survival of patients received cisplatin treatment. NHERF1 overexpression inhibited proliferation and enhanced apoptosis in cisplatin-resistant HeLa cells, whereas NHERF1 knockdown had inverse effects. While parental HeLa cells were more resistant to cisplatin after NHERF1 knockdown, NHERF1 overexpression in CaSki cells promoted cisplatin sensitivity. Overexpression and knockdown studies also showed that NHERF1 significantly inhibited AKT and extracellular signal–regulated kinase (ERK) signaling pathways in cisplatin-resistant cells. Taken together, our results provide the first evidence that NHERF1 can sensitize cisplatin-refractory cervical cancer cells. This study may help to increase understanding of the molecular mechanisms underlying cisplatin resistance in tumors. PMID:28085111

    Cervical cancer survivors treated with radiotherapy report vaginal inelasticity and decreased lubrication that may affect their sexual health, but it is unknown which normal tissue reactions mediate these symptoms. The aim of this study was to investigate the morphology of the connective tissue of the vaginal wall in cervical cancer survivors treated with radiotherapy. We recruited 34 cervical cancer survivors treated with radiotherapy and 37 age-matched controls. Via clinical examination the degree of vaginal atrophy and pelvic fibrosis were estimated. We collected vaginal biopsies, which underwent morphometric analysis focused on elastin and collagen. Additionally, radiation dose at biopsy site were calculated and correlated to the clinical and morphological findings. The survivors had marked morphological vaginal changes, most prominent in the survivors that had received the highest radiation dose at the biopsy site. Mucosal atrophy was observed in 91% and pelvic fibrosis in 97%. A shorter vagina was measured; 7.0 cm versus 10.3 cm in controls (p cancer survivors that had received external radiation. We found drastic differences in the vaginal wall between the irradiated cervical cancer survivors and the controls, indicating that radiotherapy-induced vaginal symptoms are mediated by connective tissue fibrosis and elastosis. Our results also support that patients treated with external radiation have the highest risk of developing vaginal fibrosis with impairment of their sexual health.

    Cervical cancer is one of the most common female malignancies, and cisplatin-based chemotherapy is routinely utilized in locally advanced cervical cancer patients. However, resistance has been the major limitation. In this study, we found that Na⁺/H⁺ Exchanger Regulatory Factor 1 (NHERF1) was downregulated in cisplatin-resistant cells. Analysis based on a cervical cancer dataset from The Cancer Genome Atlas (TCGA) showed association of NHERF1 expression with disease-free survival of patients received cisplatin treatment. NHERF1 overexpression inhibited proliferation and enhanced apoptosis in cisplatin-resistant HeLa cells, whereas NHERF1 knockdown had inverse effects. While parental HeLa cells were more resistant to cisplatin after NHERF1 knockdown, NHERF1 overexpression in CaSki cells promoted cisplatin sensitivity. Overexpression and knockdown studies also showed that NHERF1 significantly inhibited AKT and extracellular signal-regulated kinase (ERK) signaling pathways in cisplatin-resistant cells. Taken together, our results provide the first evidence that NHERF1 can sensitize cisplatin-refractory cervical cancer cells. This study may help to increase understanding of the molecular mechanisms underlying cisplatin resistance in tumors.

    Full Text Available Background: Malawi provides cervical cancer screening services free of charge at some public health facilities. Few women make use of these cancer screening services in Malawi and many women continue to be diagnosed with cervical cancer only during the late inoperable stages of the condition. Objectives: The purpose of this study was to discover whether the perceived susceptibility to cervical cancer, amongst Malawian women aged 42 and older, influenced their intentions to utilise the available free cervical cancer screening services. Method: A quantitative, cross-sectional descriptive study design was adopted. Structured interviews were conducted with 381 women who visited 3 health centres in the Blantyre District of Malawi. Results: A statistically-significant association existed between women’s intentions to be screened for cervical cancer and their knowledge about cervical cancer (X² = 8.9; df = 1; p = 0.003 and with having heard about HPV infection (X² = 4.2; df = 1; p = 0.041 at the 5% significance level. Cervical cancer screening services are provided free of charge in government health institutions in Malawi. Nevertheless, low perceived susceptibility to cervical cancer amongst women, aged 42 and older, might contribute to limited utilisation of cervical screening services, explaining why 80% of cervical cancer patients in Malawi were diagnosed during the late inoperable stages. Conclusion: Malawian women lacked awareness regarding their susceptibility to cervical cancer and required information about the available cervical cancer screening services. Malawi’s women, aged 42 and older, must be informed about the advantages of cervical cancer screening and about the importance of effective treatment if an early diagnosis has been made. Women aged 42 and older rarely attend antenatal, post-natal, well baby or family-planning clinics, where health education about cervical cancer screening is often provided. Consequently, these women

    Cervical cancer is the most common cancer in Laos women and a screening programme, even with the PAP smear test (PAP test), has yet to be established for routine use. The Pap test is accepted as the most appropriate for cervical cancer screening in some settings but it is not commonly available in Laos hospitals, because there are few cytopathologists and gynecologists have little experience. As a pilot program, seminars for the PAP test were given in 2007 and 2008, and then PAP tests were carried out using self-sampling instrument (Kato's device) with 200 healthy volunteers in Setthathirath hospital, Laos, in 2008. The actual examination number was 196, divided into class I 104 (53.1%), class II 85 (43.3%), class IIIa 4 (2.0%), class IIIb 1 (0.5%), and class V 1 (0.5%) by modified Papanicolau classification. Four cases had menstruation. There were 6 cases with epithelial cell abnormalities including malignancy. There were 7 cases with fungus and 2 cases with trichomonas in Class II. More than 70% volunteers felt comfortable with the Kato's device and wanted to use it next time, because of the avoidance of the embarrassment and a low cost as compared with pelvic examination by gynecologists. This first trial for PAP test for healthy Laos women related to a hospital found three percent to have abnormal cervical epithelial cells. Therefore, this appraoch using a self-sampling device suggests that it should be planned for cervical cancer prevention in Laos.

    Reffering to an increase in cervical cancer in the recent years, rapid, sensitive and economical detection of human papillomaviruses (HPVs) as causative agents of cervical cancer is important. The traditional methods for the detection of HPVs in cervical cancer, such as pap smear, suffer from limitation and PCR has a potential to overcome the limitaitons. The purpose of present research work was to identify the five important strains of HPV (16, 18, 31, 33 and 45) simultaneously by Multiplex PCR application. Study was done on 100 cervical lesions of women. DNA was extracted from specimens by a genomic DNA purification kit. A 5-plex PCR was developed for the simultaneous detection of major HPV. Five pair of new primers was designed for detection of HPV 16, 18, 31, 33 and 45 by Multiplex PCR. Among the 100 evaluated samples, 82 were found positive to HPVs. In the meantime the highest rate of infection was for HPV 16. Also 30 of HPV positive samples had infections with two or more HPV types. Multiplex PCR assay used in present study can provide a rapid, sensitive and economical method for detection of viral infections and is applicable to small volumes of vaginal samples.

    Oral contraceptives may influence the risk of certain cancers. As part of the AHRQ Evidence Report, Oral Contraceptive Use for the Primary Prevention of Ovarian Cancer, we conducted a systematic review to estimate associations between oral contraceptive use and breast, cervical, colorectal, and endometrial cancer incidence. We searched PubMed, Embase, and Cochrane Database of Systematic Reviews. Study inclusion criteria were women taking oral contraceptives for contraception or ovarian cancer prevention; includes comparison group with no oral contraceptive use; study reports quantitative associations between oral contraceptive exposure and relevant cancers; controlled study or pooled patient-level meta-analyses; sample size for nonrandomized studies ≥100; peer-reviewed, English-language; published from January 1, 2000 forward. Random-effects meta-analyses were conducted by estimating pooled ORs with 95% confidence intervals (CIs). We included 44 breast, 12 cervical, 11 colorectal, and 9 endometrial cancers studies. Breast cancer incidence was slightly but significantly increased in users (OR, 1.08; CI, 1.00-1.17); results show a higher risk associated with more recent use of oral contraceptives. Risk of cervical cancer was increased with duration of oral contraceptive use in women with human papillomavirus infection; heterogeneity prevented meta-analysis. Colorectal cancer (OR, 0.86; CI, 0.79-0.95) and endometrial cancer incidences (OR, 0.57; CI, 0.43-0.77) were significantly reduced by oral contraceptive use. Compared with never use, ever use of oral contraceptives is significantly associated with decreases in colorectal and endometrial cancers and increases in breast cancers. Although elevated breast cancer risk was small, relatively high incidence of breast cancers means that oral contraceptives may contribute to a substantial number of cases. ©2013 AACR.

    Cervical cancer is the second most common cancer among females across the world. It is a preventable cancer and early detection is very feasible. This study aimed to identify which women characteristics are potentially associated with and may have an important influence on the uptake of cervical cancer screening in Kurdish women living in the west of Iran.. A cross sectional study was conducted in late 2014. A random sample of women aged 40 years and above without history of cervical cancer and identi ed as Kurdish background were selected and interviewed by two trained interviewers. Information about sociodemographic and reproductive factors, history of diseases, and cervical screening was collected using a questionnaire and women who had undergone a hysterectomy were excluded. Univariate analyses were used to describe the general characteristics of the study population. Multivariable logistic regression models with self-reported screening history were used to estimate odds ratios (ORs) with 95% con dence intervals (CI). Significance was considered at the 5% level. A total of 561 women were included in this study (mean age 43.6±5.17 years) participation in cervical screening at least once was about 32%. Cervical screening uptake percentage was significantly lower among people over 60 years of age (adjusted OR= 0.26, 95% CI: 0.11-0.64), and those who were illiterate (OR=0.41 95% CI: 0.23-0.73) and post-menopausal (OR= 0.56, 95% CI: 0.35- 0.91). Women with ≤1 child were less likely to report a Pap test (adjusted OR=.43 95%CI: 0.13-1.37) Cervical screening uptake was higher among women with health insurance (OR= 2.31, 95% CI: 1.50- 3.56). Cervical screening participation in this study was low compared to other studies in developed countries. The screening uptake was different based on age, education, parity, insurance coverage and menopausal status. It is recommended to target these groups of women in a cervical screening program.

    Human papillomavirus (HPV) causes greater than 5% of cancers worldwide, including all cervical cancers and an alarmingly increasing proportion of oropharyngeal cancers (OPCs). Despite markedly reduced cervical cancer incidence in industrialized nations with organized screening programs, cervical cancer remains the second most common cause of death from cancer in women worldwide, as developing countries lack resources for universal, high-quality screening. In the United States, HPV-related OPC is only 1 of 5 cancers with a rising incidence since 1975 and now has taken over the cervix as the most common site of HPV-related cancer. Similar trends follow throughout North America and Europe. The need for early detection and prevention is paramount. Despite the common etiologic role of HPV in the development of cervical cancer and HPV-associated OPC, great disparity exists between incidence, screening modalities (or lack thereof), treatment, and prevention in these 2 very distinct cohorts. These differences in cervical cancer and HPV-associated OPC and their impact are discussed here. Cancer 2017;123:2219-2229. © 2017 American Cancer Society. Published 2017.

It has been reported that there are CSCs in cervical cancer cells. Pluripotency-associated (PA transcription factors such as Oct4, Sox2, Nanog and CD44 have been used to isolate CSCs subpopulations. In this study, we showed that autophagy plays an important role in the biological behavior of cervical cancer cells. The expression of the autophagy protein Beclin 1 and LC3B was higher in tumorspheres established from human cervical cancers cell lines (and CaSki than in the parental adherent cells. It was also observed that the basal and starvation-induced autophagy flux was higher in tumorspheres than in the bulk population. Autophagy could regulate the expression level of PA proteins in cervical CSCs. In addition, CRISPR/Cas 9-mediated Beclin 1 knockout enhanced the malignancy of HeLa cells, leading to accumulation of PA proteins and promoted tumorsphere formation. Our findings suggest that autophagy modulates homeostasis of PA proteins, and Beclin 1 is critical for CSC maintenance and tumor development in nude mice. This demonstrates that a prosurvival autophagic pathway is critical for CSC maintenance. Keywords: cervical cancer, autophagy, cancer stem cell, LC3, Oct4

    Full Text Available Abstract Background To discover cancer specific DNA methylation markers, large-scale screening methods are widely used. The pharmacological unmasking expression microarray approach is an elegant method to enrich for genes that are silenced and re-expressed during functional reversal of DNA methylation upon treatment with demethylation agents. However, such experiments are performed in in vitro (cancer cell lines, mostly with poor relevance when extrapolating to primary cancers. To overcome this problem, we incorporated data from primary cancer samples in the experimental design. A strategy to combine and rank data from these different data sources is essential to minimize the experimental work in the validation steps. Aim To apply a new relaxation ranking algorithm to enrich DNA methylation markers in cervical cancer. Results The application of a new sorting methodology allowed us to sort high-throughput microarray data from both cervical cancer cell lines and primary cervical cancer samples. The performance of the sorting was analyzed in silico. Pathway and gene ontology analysis was performed on the top-selection and gives a strong indication that the ranking methodology is able to enrich towards genes that might be methylated. Terms like regulation of progression through cell cycle, positive regulation of programmed cell death as well as organ development and embryonic development are overrepresented. Combined with the highly enriched number of imprinted and X-chromosome located genes, and increased prevalence of known methylation markers selected from cervical (the highest-ranking known gene is CCNA1 as well as from other cancer types, the use of the ranking algorithm seems to be powerful in enriching towards methylated genes. Verification of the DNA methylation state of the 10 highest-ranking genes revealed that 7/9 (78% gene promoters showed DNA methylation in cervical carcinomas. Of these 7 genes, 3 (SST, HTRA3 and NPTX1 are not

    Cervical cancer is the second most common cancer among women worldwide, with developing countries accounting for >80% of the disease burden. Although in the West, active screening has been instrumental in reducing the incidence of cervical cancer, disease management is hampered due to lack of biomarkers for disease progression and defined therapeutic targets. Here we carried out gene expression profiling of 29 cervical cancer tissues from Indian women, spanning International Federation of Gynaecology and Obstetrics (FIGO) stages of the disease from early lesion (IA and IIA) to progressive stages (IIB and IIIA–B), and identified distinct gene expression signatures. Overall, metabolic pathways, pathways in cancer and signaling pathways were found to be significantly upregulated, while focal adhesion, cytokine–cytokine receptor interaction and WNT signaling were downregulated. Additionally, we identified candidate biomarkers of disease progression such as SPP1, proliferating cell nuclear antigen (PCNA), STK17A, and DUSP1 among others that were validated by quantitative real-time polymerase chain reaction (qRT-PCR) in the samples used for microarray studies as well in an independent set of 34 additional samples. Integrative analysis of our results with other cervical cancer profiling studies could facilitate the development of multiplex diagnostic markers of cervical cancer progression

    Women living with HIV (WLWH) are reportedly at increased risk of invasive cervical cancer (ICC). A recent publication found that WLWH in Denmark attend the national ICC screening programme less often than women in the general population. We aimed to estimate the incidence of cervical dysplasia and ICC in WLWH in Denmark compared with that in women in the general population. We studied a nationwide cohort of WLWH and a cohort of 15 age-matched women per WLWH from the general population for the period 1999-2010. Pathology samples were obtained from The Danish Pathology Data Bank, which contains nationwide records of all pathology specimens. The cumulative incidence and hazard ratios (HRs) for time from inclusion to first cervical intraepithelial neoplasia (CIN)/ICC and time from first normal cervical cytology result to first CIN/ICC were estimated. Sensitivity analyses were performed to include prior screening outcome, screening intensity and treatment of CIN/ICC in the interpretation of results. We followed 1140 WLWH and 17 046 controls with no prior history of ICC or hysterectomy for 9491 and 156 865 person-years, respectively. Compared with controls, the overall incidences of CIN1 or worse (CIN1+), CIN2+ and CIN3+, but not ICC, were higher in WLWH and predicted by young age and a CD4 count < 200 cells/μL. In women with normal baseline cytology, incidences of CIN1+ and CIN2+ were higher in WLWH. However, when we compared subgroups of WLWH and controls where women in both groups were adherent to the national ICC screening programme and had a normal baseline cytology, incidences of CIN and ICC were comparable. Overall, WLWH developed more cervical disease than controls. Yet, in WLWH and controls adherent to the national ICC screening programme and with normal baseline cytology, incidences of CIN and ICC were comparable. © 2015 British HIV Association.

    It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients. Caudal epidural anesthesia for 34 cervical cancer patients was performed during HDR intracavitary brachytherapy between October 2011 and August 2013. We used the patients' self-reported Numeric Rating Scale (NRS) score at the first session of HDR intracavitary brachytherapy as a subjective evaluation of pain. We compared NRS scores of the patients with anesthesia with those of 30 patients who underwent HDR intracavitary brachytherapy without sacral epidural anesthesia at our hospital between May 2010 and August 2011. Caudal epidural anesthesia succeeded in 33 patients (97%), and the NRS score was recorded in 30 patients. The mean NRS score of the anesthesia group was 5.17 ± 2.97, significantly lower than that of the control group's 6.80 ± 2.59 (P = 0.035). The caudal epidural block resulted in no side-effects. Caudal epidural anesthesia is an effective and safe anesthesia option during HDR intracavitary brachytherapy for cervical cancer. (author)

    Early detection of cervical cancer substantially increases the probability of cure. The aim of this study was to determine the prevalence and factors associated with non-participation in cervical cancer screening among women 15 to 49 years of age in Rio Grande, Southern Brazil. A representative survey was carried out using a systematic sample based on a census tract. Trained interviewers used standard, individualized, household questionnaires to interview the women. Data analysis used logistic regression according to a previously determined hierarchical framework. Among 1,302 women interviewed, 57% had never had a Pap smear. The risk factors most closely associated with non-participation in screening were black or brown skin color, young age, low family income, low schooling, living alone, and first childbirth after 25 years of age. Coverage for early detection of cervical cancer was very low. In addition, women at high risk of developing cervical cancer were shown to have a significantly higher risk of non-participation in this type of screening.

    The objective of this study was to determine the impact of Pap test compliance and cervical cancer screening intervals on human papillomavirus (HPV) vaccination acceptance. A convenience sample of 499 women 21 to 65 years old completed a 37-question survey in Augusta and Savannah, GA. The survey assessed their knowledge about HPV, cervical cancer, and the HPV vaccine. The questionnaire also determined their Pap test compliance and how longer Pap test intervals would influence their willingness to receive the HPV vaccine. Differences between categorical variables and knowledge scores were examined using χ test and unequal-variance t tests, respectively. Pap test-noncompliant women were more likely to get the HPV vaccine if they only needed a Pap test every 10 years compared with Pap test-compliant women (27.6% vs 14.6%, p = .02). A greater number (83.5%) of Pap test-noncompliant women preferred the HPV vaccine plus every 10-year Pap test option compared with Pap test-compliant women (31.3%, p Pap testing. Women are receptive to getting the HPV vaccine in exchange for longer cervical cancer screening intervals. Moreover, Pap test-noncompliant women are more likely to get the HPV vaccine if Pap testing was needed less frequently. Increasing the Pap testing interval may be an excellent method to improving HPV vaccine acceptance in women at highest risk for cervical cancer.

    Cervical cancer and cervical intraepithelial neoplasia (CIN) are well-known outcomes of a human papillomavirus (HPV) infection. Viral oncogenes expressions like E6, E7, and, recently recognized E5, lead to HPV-related malignant progression. Although HPV prevention by powerful vaccines against most frequent and oncogenic genotypes is feasible, current treatment against cervical neoplasia is distant from an ideal one. In addition, late diagnosis is commonly associated with a poor prognosis. On top of that, radiotherapy, chemotherapy, or surgery are less effective in high-grade lesions. Areas covered: Due to their peculiarities, HPV oncogenes represent an excellent target for cancer immunotherapy. Safety, efficacy, and potential immunogenicity are features achieved by DNA vaccines targeting HPV. The literature search has indicated that genetic immunotherapy is becoming a pharmacological tool and therapeutic option against cervical disease, as more and more DNA vaccines are reaching clinical trial phases. Expert commentary: Among some of the promising results, a phase II randomized trial showed a clinical activity of a nucleic acid-based vaccine in HPV16 or HPV18 positive CIN patients. The concept of a synergic combination of anti-HPV DNA vaccines with radiotherapy, chemotherapy, sophisticated delivery methods, immunomodulators or immune adjuvants opens a new and interesting perspective in cervical malignancy treatment.

    Cancer screening programs have been successful in reducing the incidence and mortality due to cervical cancer. For more than a decade, the human papillomavirus test has been recommended as part of these programs, however, Pap tests is not currently recommended for women 65 years of age who participated adequately in screening programs, continuing with these screening programs is not needed. Screening programs will be different in special populations at greatest risk where tests are frequently needed or use of alternative methods.

    Prior research has noted disparities between women with and without disabilities in receipt of timely screening for breast and cervical cancer. Some studies suggest greater disparities for women with more severe disabilities, but the research to date has yielded inconsistent findings. Our purpose was to further examine differences in receipt of breast and cervical cancer screening in relation to severity of disability. We analyzed Medical Expenditure Panel Survey annual data files from 2002 to 2008. Logistic regression analyses examined whether Pap smears and mammograms had been received within the recommended timeframe according to U.S. Preventive Services Task Force Guidelines. We compared four groups of women aged 18 to 64 years, categorized by presence and complexity of disability: 1) No limitations, 2) basic action difficulties only, 3) complex activity limitations only, and 4) both basic and complex activity limitations. Women both with and without disabilities fell short of Healthy People 2020 goals for breast and cervical cancer screening. Overall, women with disabilities were less likely to be up to date with both mammograms and Pap tests. The magnitude of disparities was greater for women with complex limitations. Disparities in Pap testing, but not mammography, remained significant when controlling for demographic, geographic, and socioeconomic factors. Women with more complex or severe disability were less likely to be up to date with breast and cervical cancer screenings. Targeted efforts are needed to reduce barriers to breast and cervical cancer screening for women with significant disabilities, especially those who also experience other socioecological disadvantages.

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

    Cisplatin resistance is still one of the main reasons for failure of clinical therapy for cervical cancer. But the underlying molecular mechanisms involved in cisplatin resistance of cervical cancer have still remained unclear. Recent studies reported that long noncoding RNAs (lncRNAs) are novel nonprotein-coding transcripts, which might play a key role in cancer biogenesis and prognosis. One of the lncRNAs, urothelial cancer associated 1 (UCA1), has been shown to promote different types of cancer cell proliferation, migration, and invasion. This study showed that overexpression of UCA1 confers cisplatin resistance by promoting cancer cell proliferation and inhibiting apoptosis. In addition, knockdown of UCA1 remarkably decreased cisplatin resistance in cervical cancer cells. Moreover, results also indicated that UCA1 was involved in signaling pathways modulating cell apoptosis and proliferation. UCA1 suppressed apoptosis by downregulating caspase 3 and upregulating CDK2, whereas enhanced cell proliferation by increased level of survivin and decreased level of p21. This study reports for the first time that UCA1 might play an important role in the cisplatin resistance in cervical cancer, and also explain partially how UCA1 promotes cisplatin resistance in cancer cells. These results provide evidence to support that UCA1 can be used as a potential target for a novel therapeutic strategy for cervical cancer.

    To assess cancers diagnosed and the stage of cancer at the time of diagnosis among low-income, under-insured, or uninsured women who received services through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Using the NBCCEDP database, we examined the number and percent of women diagnosed during 2009-2011 with in situ breast cancer, invasive breast cancer, and invasive cervical cancer by demographic and clinical characteristics, including age, race and ethnicity, test indication (screening or diagnostic), symptoms (for breast cancer), and screening history (for cervical cancer). We examined these characteristics by stage at diagnosis, a new variable included in the database obtained by linking with state-based central cancer registries. There were 11,569 women diagnosed with invasive breast cancer, 1,988 with in situ breast cancer, and 583 with invasive cervical cancer through the NBCCEDP. Women who reported breast symptoms or who had diagnostic mammography were more likely to be diagnosed with breast cancer, and at a later stage, than those who did not have symptoms or who had screening mammography. Women who had been rarely or never screened for cervical cancer were more likely to be diagnosed with cervical cancer, and at a later stage, than women who received regular screenings. Women served through the NBCCEDP who have not had prior screening or who have symptoms were more often diagnosed with late-stage disease.

    Non-attendance at gynecological clinics is a major limitation of cervical cancer screening and self-collection of samples may improve this situation. Although HPV testing of self-collected vaginal samples is acceptable, the specificity is inadequate. The current focus is increasing self-collection of vaginal samples to minimize clinic visits. In this study, we analyzed the concordance and clinical performance of DNA methylation biomarker (PAX1, SOX1, and ZNF582) detection in self-collected vaginal samples and physician-collected cervical samples for the identification of cervical neoplasm. We enrolled 136 cases with paired methylation data identified from abnormal Pap smears (n = 126) and normal controls (n = 10) regardless of HPV status at gynecological clinics. The study group comprised 37 cervical intraepithelial neoplasm I (CIN1), 23 cervical intraepithelial neoplasm II (CIN2), 16 cervical intraepithelial neoplasm III (CIN3), 30 carcinoma in situ (CIS), 13 squamous cell carcinomas (SCCs) and seven adenocarcinomas (ACs)/adenosquamous carcinomas (ASCs). PAX1, SOX1 and ZNF582 methylation in study samples was assessed by real-time quantitative methylation-specific polymerase chain reaction analysis. We generated methylation index cutoff values for the detection of CIN3+ in physician-collected cervical samples for analysis of the self-collected group. Concordance between the physician-collected and self-collected groups was evaluated by Cohen’s Kappa. Sensitivity, specificity and area under curve (AUC) were calculated for detection of CIN3+ lesions. Finally, we produced an optimal cutoff value with the best sensitivity from the self-collected groups. We generated a methylation index cutoff value from physician-collected samples for detection of CIN3+. There were no significant differences in sensitivity, specificity of PAX1, SOX1 and ZNF582 between the self-collected and physician-collected groups. The methylation status of all three genes in the normal control

    Based on blood plasma surface-enhanced Raman spectroscopy (SERS) analysis, a simple and label-free blood test for non-invasive cervical cancer detection is presented in this paper. SERS measurements were performed on blood plasma samples from 60 cervical cancer patients and 50 healthy volunteers. Both the empirical approach and multivariate statistical techniques, including principal component analysis (PCA) and linear discriminant analysis (LDA), were employed to analyze and differentiate the obtained blood plasma SERS spectra. The empirical diagnostic algorithm based on the integration area of the SERS spectral bands (1310-1430 and 1560-1700 cm(-1)) achieved a diagnostic sensitivity of 70% and 83.3%, and a specificity of 76% and 78%, respectively, whereas the diagnostic algorithms based on PCA-LDA yielded a better diagnostic sensitivity of 96.7% and a specificity of 92% for separating cancerous samples from normal samples. This exploratory work demonstrates that a silver nanoparticle based SERS plasma analysis technique in conjunction with PCA-LDA has potential for improving cervical cancer detection and screening.

    Treatment results of neck dissection with the preservation of cervical nerves for hypopharyngeal cancer were analyzed retrospectively by comparing neck dissection with the preservation of cervical nerves and that with the resection of cervical nerves. Pharyngolaryngectomy or pharyngolaryngoesophagectomy with bilateral neck dissection was performed in 76 hypopharyngeal cancer cases between January 1992 and November 2001. Neck dissection with the resection of cervical nerves was performed on 42 sides of the neck in 21 cases (the cervical nerve-resected group). In 55 cases we attempted to employ neck dissection with the preservation of cervical nerves, but in 9 cases the cervical nerves were resected because of their nodal adhesion or involvement Neck dissection with the preservation of cervical nerves was performed on 92 sides of the neck in 46 cases (the cervical nerve-preserved group). There were significant differences between background factors of two groups about age, sex, induction chemotherapy, preservation of accessory nerve, and pN classification. The 5-year cumulative control rates of cervical lymph nodes were 81.3% for the cervical nerve-resected group and 79.7% for the cervical nerve-preserved group. There was no significant difference between the two groups. It was suggested that neck dissection with the preservation of cervical nerves for cases whose cervical nerves were able to be preserved from metastatic lymph nodes under induction chemotherapy and post-operative irradiation was as effective to control cervical lymph nodes as neck dissection with the resection of cervical nerves.

    The malignancy of the cervix is one of the few locations avoidable cancers, if detected before it progresses to the infiltration. The most efficient way of early detection is through a screening program to provide women undertaking a regular and quality Pap smear. If this test results abnormal, the program offers easier access to specialized care, effective treatment, and follow-up. The objective of this article is to present usefulness of methods for quality control used in screening programs for cervical cancer to detect their inadequacies. Here are some factors and conditions that must be considered in each of the steps to take, for a cervical cancer screening program to be successful and to meet the objectives proposed in reducing mortality due to this cause.

    Cervical cancer takes the lives of more than 250,000 women each year globally, particularly in under-resourced areas of low-, middle-, and high-income countries. Options for cancer control and treatment have reached a point that there are interventions for control that could be adopted for virtually every resource and demographic situation. Women die despite the availability of attractive control options, which means that educating policy makers, women's health professionals, as well as women themselves, must become a major focus for ongoing control of this disease. The human right to life, to prevention of suffering, and to education are all key rights linked to improving the control of cervical cancer and saving the lives of women, particularly in resource-poor parts of the world.

    To determine the diagnostic performance of hematuria as a screening test for urinary bladder infiltration in cervical cancer patients with a prospective study design. Newly diagnosed cervical cancer patients at Srinagarind hospital from 14 June 2011 to 30 April 2012 were enrolled in this study. We collected midstream urine samples for urinalysis from every patient before routine cystoscopic exam for clinical staging. The presence of 3 or more red blood cells (RBCs) per high power field was defined as positive for hematuria. A two-by-two table was used to determine the diagnostic performance of hematuria to detect urinary bladder mucosal infiltration using cystoscopy and biopsy as the gold standard. A total of 130 were patients included, 54 of which (41.5%) had hematuria. Of these, four patients (3.08%) had pathological report from cystoscopic biopsy confirmed metastatic squamous cell carcinoma. The sensitivity, specificity, PPV, NPV, and accuracy of hematuria as a screening test to detect urinary bladder mucosal infiltration of cervical cancer were 100%, 60.3%, 7.4%, 100%, and 61.5%, respectively. There was no single case of urinary bladder mucosal infiltration in patients initially staged less than stage III. Hematuria can be used as a screening test to detect urinary bladder mucosal infiltration of cervical cancer. This can reduce the number of cervical cancer patients who really need to undergo cystoscopy as a staging procedure to less than half and to less than 20% if stage III or more were included without missing a single case of urinary bladder mucosal infiltration.

    Background The β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3) encodes a member of the B3GNT family that functions as the backbone structure of dimeric sialyl-Lewis A and is involved in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. B3GNT3 has been implicated as an important element in the development of certain cancers. However, the characteristics of B3GNT3 in the development and progression of cancer remain largely unknown. Thus, our study aimed to investigate the expression pattern and the prognostic value of B3GNT3 in patients with early-stage cervical cancer. Methods The mRNA and protein levels of B3GNT3 expression were examined in eight cervical cancer cell lines and ten paired cervical cancer tumors, using real-time PCR and western blotting, respectively. Immunohistochemistry (IHC) was used to analyze B3GNT3 protein expression in paraffin-embedded tissues from 196 early-stage cervical cancer patients. Statistical analyses were applied to evaluate the association between B3GNT3 expression scores and clinical parameters, as well as patient survival. Results B3GNT3 expression was significantly upregulated in cervical cancer cell lines and lesions compared with normal cells and adjacent noncancerous cervical tissues. In the 196 cases of tested early-stage cervical cancer samples, the B3GNT3 protein level was positively correlated with high risk TYPES of human papillomavirus (HPV) infection (P = 0.026), FIGO stage (P cervical cancer patients. Conclusions Our study demonstrated that elevated B3GNT3 expression is associated with pelvic lymph node metastasis and poor outcome in early-stage cervical cancer patients. B3GNT3 may be a novel prognostic marker and therapeutic target for the treatment of cervical cancer. PMID:26709519

    Cervical cancer is one of the most common carcinomas in the female reproductive system. Treatment of cervical cancer involves surgical removal and chemotherapy. Resistance to platinum-based chemotherapy drugs including cisplatin has increasingly become an important problem in the treatment of cervical cancer patients. We found in this study that stanniocalcin 2 (STC2) expression was upregulated in both cervical cancer tissues and cell lines. The levels of STC2 expression in cervical cancer cell lines were positively correlated with the rate of cell proliferation. Furthermore, in cisplatin resistant cervical cancer cells, the levels of STC2 expression were significantly elevated. Modulation of STC2 expression by siRNA or overexpression in cisplatin resistant cells resulted in altered cell survival, apoptosis, and cisplatin resistance. Finally, we found that there was significant difference in the activity of the MAPK signaling pathway between cisplatin sensitive and resistant cervical cancer cells, and that STC2 could regulate the activity of the MAPK signaling pathway. - Highlights: • STC2 was upregulated in cervical cancer and promoted cervical cancer cell proliferation. • Cisplatin resistant cells had elevated STC2 levels and enhanced proliferation. • STC2 regulated cisplatin chemosensitivity in cervical cancer cells. • STC2 regulated the activity of the MAPK signaling pathway.

    Full Text Available Background: This study evaluated sexual function in cervical cancer survivors after concurrent chemoradiotherapy. Methods: Study participants comprised survivors of locally advanced cervical cancer (stages IIB-IVA who completed concurrent chemoradiotherapy along with intracavitary brachytherapy at least two years prior at Dr S.N.Medical College, Jodhpur, Rajasthan, India. We used the Female Sexual Function Index questionnaire to assess sexual function. The cut-off score of the Female Sexual Function Index that identified female sexual arousal disorder was 26.55. A score less than 26.55 indicated the presence of female sexual arousal disorder. Results:A total of 48 locally advanced cervical cancer survivors enrolled in the study. Survivors had a mean age of 46.5 years. All received chemoradiotherapy along with intracavitary brachytherapy. The average time for treatment was 53.5 days. Patients had an average score for sexual desire of 2, 2.3 for arousal, 2.3 for sexual satisfaction, and 2.1 for pain during intercourse. The overall average score was 11.84 (range: 3.2-19.5 with a cut-off of 26.55. All survivors suffered from female sexual arousal disorder. Conclusion: Cervical cancer survivors had decreased sexual function which indicated female sexual arousal disorder. Patient education and active treatment of complications related to cancer treatments is a must for improvement of sexual function among survivors. Long-term complications should be considered in terms of treatment planning and follow-up treatment to improve the quality of life of cancer survivors.

    Cervical cancer outcomes remain poor among disadvantaged populations, including ethnic minorities, low-income, and underinsured women. The aim of this study was to evaluate the mechanisms that underlie the observed association between race/ethnicity and cervical cancer survival. We identified 13,698 women, ages 21 to 64 years, diagnosed with stages I-III primary cervical cancer between 2007-2013 in Surveillance, Epidemiology, and End Results (SEER). Multivariable Cox proportional hazards regression models evaluated associations between race/ethnicity (Non-Hispanic White, Non-Hispanic Black, Hispanic, Other) and cervical cancer-specific mortality. We conducted mediation analysis to calculate the mediation proportion and its 95% confidence interval. Non-Hispanic black women had an increased risk of cervical cancer-specific mortality (HR: 1.23, 95% CI: 1.08-1.39), and Hispanic women a decreased risk of dying from their disease (HR: 0.82, 95% CI: 0.72-0.93), compared with non-Hispanic white. The estimated proportion of excess cervical cancer mortality for non-Hispanic black women relative to non-Hispanic white women that was mediated by insurance was 18.6% and by treatment was 47.2%. Furthermore, non-Hispanic black women were more likely to receive radiation and less likely to receive surgery for early-stage disease. In this population-based study we found that some of the excess cervical cancer-specific mortality for non-Hispanic black women is mediated by factors such as insurance status and treatment. These findings suggest that enhancing existing insurance coverage and ensuring equal and adequate treatment in all women may be a key strategy for improving cervical cancer outcomes.

    To determine which groups of women would be most likely to take part in self-sampling for cervical screening, and what they perceive as the key barriers and benefits to self-sampling. A random sample of 3000 women aged 18-69 in Victoria, Australia, were asked questions about "taking their own Pap test" in a telephone survey about cervical screening; 2526 answered the questions about self-sampling. The terminology "Pap test" was used in questions, due to the very low understanding of HPV and its link to cervical cancer. One-third of women (34.0%) indicated they would prefer to self-sample, 57.2% would not and 8.7% were unsure. Preference for self-sampling was significantly stronger among women who had not had a Pap test for more than three years (64.8%, p Pap test, and could potentially reach some women who are not participating appropriately in cervical screening. Key barriers to participation could be addressed by providing information about the test being for HPV, and being easier to do properly than a Pap test. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available A carcinogênese é um processo de múltiplas etapas. Alterações no equilíbrio citogenético ocorrem na transformação do epitélio normal a câncer cervical. Numerosos estudos apoiam a hipótese de que a infecção por HPV está associada com o desenvolvimento de alterações malignas e pré-malignas do trato genital inferior. Neste trabalho são apresentadas as bases para a compreensão da oncogênese cervical. O ciclo celular é controlado por proto-oncogenes e genes supressores. Quando ocorrem mutações, proto-oncogenes tornam-se oncogenes, que são carcinogênicos e causam multiplicação celular excessiva. A perda da ação de genes supressores funcionais pode levar a célula ao crescimento inadequado. O ciclo celular também pode ser alterado pela ação de vírus, entre eles o HPV (Human Papiloma Virus, de especial interesse na oncogênese cervical. Os tipos de HPV 16 e 18 são os de maior interesse, freqüentemente associados a câncer cervical e anal. O conhecimento das bases moleculares que estão envolvidas na oncogênese cervical tem sido possível devido a utilização de técnicas avançadas de biologia molecular. A associação destas técnicas aos métodos diagnósticos clássicos, poderão levar a uma melhor avaliação das neoplasias cervicais e auxiliar no desenvolvimento de novas terapias, talvez menos invasivas e mais efetivas.Carcinogenesis involves several steps. Disorders of the cytogenetic balance occur during the evolution from normal epithelium to cervical cancer. Several studies support the hypothesis that the Human Papiloma Virus (HPV infection is associated to development of premalignant and malignant lesions of cervical cancer. In this review we show the basis to understand cervical oncogenesis. The cell cycle is controlled by protooncogenes and supressive genes. This orchestrated cell cycle can be affected by virus such as HPV. Of special interest in the cervical carcinogenesis are the HPV subtypes 16 and 18

    To characterize the age and pattern of Pap smear abnormalities in a major teaching hospital in Southwestern Nigeria. This is a review of medical records of patients that came for cervical cancer screening. The Pap smear results of women between May 2013 and April 2015 were retrieved. A total of 2048 Pap smear results were retrieved during the study period and analyzed with Statistical Package for Social Sciences (SPSS) version 20. A total of 252 (12.3%) samples were excluded from the analysis. The mean age of the women was 45.77 ± 9.9 years and the mode was 50 years. Normal Pap smear result was reported in 728 (40.6%) women. Only 20 women has had more than one more than one Pap smear done. The most common abnormality was inflammatory smear result as this was reported in 613 (29.9%) women. Atypical squamous cell of undetermined significance, low-grade squamous intraepithelial lesion (LGSIL), and high-grade squamous intraepithelial lesion (HGSIL) were reported in 117 (5.7%), 209 (10.2%), and 111 (5.4%) women, respectively. Atypical glandular cell and squamous cell carcinoma were reported in 12 (6.0%) and 3 (1.0%), respectively. There is a high incidence of abnormal Pap smear in this environment and women start cervical cancer screening late in their reproductive life, past the age at which cervical premalignant lesions peak. This may be a contributing factor to the high burden of cervical cancer in developing countries.

    The newly gained knowledge of the viral etiology in cervical carcinogenesis has prompted industrial interests in developing virology-based tools for cervical cancer prevention. Due to the long incubation period from viral infection to developing an invasive cancer, a process whose outcome is influenced by numerous life-style and genetic factors, the true efficacy of the genotype-specific human papillomavirus (HPV) vaccines in cervical cancer prevention cannot be determined for another 30 years. Most HPV DNA test kits designed to replace the traditional Papanicolaou (Pap) smears for precancer detection lack the analytical sensitivity and specificity to comprehensively detect all potentially carcinogenic HPVs and to perform reliable genotyping. The authors implemented the classic nested PCR and Sanger DNA-sequencing technology for routine HPV testing. The results showed a true negative HPV PCR invariably indicates the absence of precancerous cells in the cytology samples. However, 80.5% of single positive HPV-16 tests and 97.3% of single positive HPV-18 tests were associated with a negative or a largely self-reversible Pap cytology. Routine sensitive and reliable HPV type-specific or perhaps even variant-specific methods are needed to address the issues of persistence of HPV infection if a virology-based primary cervical screen is used to replace the Pap cytology screening paradigm

    Cervical cancer continues to be the commonest cause of death among women in developing countries, largely due to the failure to the inability to sustain effective cytology-based screening programs. While this burden may come down following implementation of the human papillomavirus (HPV) vaccine, screening will still be required. HPV DNA testing is a promising new technology for cervical cancer prevention and is the most reproducible of all cervical cancer screening tests. Presently, the two assays most widely used for the detection of genital types are the polymerase chain reaction (PCR) and Hybrid Capture 2 assays (hc2). Rapid, affordable tests are expected to be available soon. HPV DNA testing can be used in a variety of clinical scenarios that include primary screening in women older than 30 yr; as an adjunctive test to cytology; in the triage of women with an equivocal cytologic report, e.g., ASC-US; or for follow-up post-treatment for cervical intraepithelial neoplasia (CIN). HPV DNA testing can also be performed on self-collected samples, which allows screening in remote areas and also in women who refuse gynecologic examination.

    Cervical cancer is a major cause of mortality in Uighur women compared with Han women in the Xinjiang region of China. Although a reduction in the class i major histocompatibility complex (mhc-i) antigen processing machinery (apm) is associated with the development of cervical cancer, the mhc-i apm has not been studied in this particular group of women, who have the highest incidence rate of cervical cancer in China. We used immunohistochemical staining and polymerase chain reaction amplification of viral dna from infection with the human papilloma virus (hpv) to study the expression of members of the mhc-i apm in cervical cancer sections collected from Uighur and Han women and in cervicitis samples from age-matched counterparts. Expression of the molecules of interest was compared between two ethnic groups, and expression of transporter associated with antigen processing 1 and 2, heat shock protein 90, and calnexin were found to be reduced even more significantly in Han women with cervical cancer than in Uighur women with same disease. However, compared with Han women, Uighur women had a higher rate of infection with hpv 16. The mhc-i apm were reduced in cervical cancer, with heterogeneity in the two ethnic groups. The reduction was more pronounced in Han women, who less frequently had hpv 16 infection, suggesting possible differences in the roles of members of the mhc-i apm and in the mechanisms of cervical cancer development in these two ethnic groups despite residence in the same region of China.

    Oral contraceptives (OCs) remain among the most effective reversible methods of birth control available today, providing almost 100% effectiveness with an impressively high margin of safety and other important health benefits. However, concerns have been raised about the role that the hormones in OCs might play in the pathogenesis of cervical cancer. Evidence shows that long-term use of OCs (five or more years) may be associated with an increased risk of cancer of the cervix. The mechanism of increased risk of cervical cancer in OCs users has long been debated, and remains uncertain. Our hypothesis is that scanty, thick, and highly viscous cervical mucus obtained in OCs users intimately involved in the pathogenesis of cervical cancer. Possibly, this architecture of cervical mucus may modulate and prolong the effect of carcinogenic agents, which have been carried by coitus and stored in posterior vaginal fornix, on squamocolumnar junction of cervix by not permitting them to be removed because of its highly viscous pattern. The role of cervical mucus changes by means of specific mucin protein changes on the pathophysiology of cervical cancer in OCs users should be investigated.

    Testing for human papillomavirus (HPV) is being incorporated into the cervical screening programme, with the probable future introduction of HPV as a primary test and a possibility of HPV self-sampling. In anticipation of this development, we sought to inform future policy and practice by identifying potential barriers to HPV self-sampling. A cross-sectional survey of 194 women aged 20-64 years was conducted. Logistic regression analysis was used to identify determinants of self-sampling intentions. A purposive subsample of 19 women who reported low self-sampling intentions were interviewed. Interviews were framework-analysed. Most survey participants (N=133, 69.3%) intended to HPV self-sample. Lower intention was associated with lower self-efficacy (OR=24.96, P≤.001), lower education (OR=6.06, P≤.05) and lower perceived importance of HPV as a cause of cervical cancer (OR=2.33, P≤.05). Interviews revealed personal and system-related barriers. Personal barriers included a lack of knowledge about HPV self-sampling, women's low confidence in their ability to self-sample correctly and low confidence in the subsequent results. System-related factors included a lack of confidence in the rationale for modifying the current cervical screening programme, and concerns about sample contamination and identity theft. Insights gained from this research can be used to guide further enquiry into the possibility of HPV self-sampling and to help inform future policy and practice. Personal and system-related barriers including low confidence in the reasons for changing current cervical screening provision need to be addressed, should HPV self-sampling be incorporated into the cervical screening programme. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    Early detection of cervical cancer improves the chances of successful treatment. The aim of this study was to determine the effect of education about cervical cancer and human papillomavirus on the healthy lifestyle, behavior, and beliefs of Turkish women who were without cancer, using the PRECEDE education model. This qualitative and quantitative study was conducted as a prospective, randomized, 2-group (intervention and control) trial at a community training center in north Turkey. A total of 156 Turkish women who were without cancer participated in this study. The semistructured interview form, the SF-36 Health Status Questionnaire, the Health Belief Model Scale for Cervical Cancer and Pap Smear Test, and the Healthy Lifestyle Behavior Scale II were used. The subdimension scores of the Health Belief Model Scale for Cervical Cancer and Pap Smear Test were found to be higher among women in the study group (cervical cancer seriousness, P = .001; health motivation, P = .001) as compared with the control group after the education program. The SF-36 Health Status Questionnaire domain scores for physical role limitations, mental role limitations, and general health perceptions increased in the study group after the intervention. The posteducation health motivation of women in the study group was improved, the women's perceptions of obstacles to Papanicolaou testing decreased, and through increased knowledge and awareness, the rate of Papanicolaou testing increased. Educational programs aimed at motivating women to increase their awareness of cervical cancer, preventing cervical cancer, and having Papanicolaou testing are necessary and beneficial in this sample.

    The non-participation to cervical screening is the major determinant in the risk of mortality due to cervical cancer. In France, around 40% of women do not participate to regular screening. The cultural or economic barriers for performing screening by Pap test are numerous; one of the most frequent is the refusal of gynaecological examination. A persistent HPV(HR) infection is a necessary factor for developing cervical cancer. The HPV(HR) testing has a high sensibility to detect high grade cervical intra-epithelial neoplasia (CIN 2-3) and a satisfactory specificity after 30-35 years old. The principal objective of this study was to compare the participation rates in women 35-69 years old who did not perform a Pap test after a first individual invitation, either when an HPV(HR) auto-test was offered to be performed at home or a second invitation to Pap test was sent. We also evaluated the quality of the two tests, the positive results obtained by age groups and the following histological type of lesions diagnosed in the women with positive results. The study included 9,334 women, 35-69 years old, who did not realized a Pap-test during the 2 previous years and who did not respond at a first individual invitation. These non-responders were randomized into two groups: one group (n=4,934) received a second individual invitation and the other (n=4,400) an offer of receiving and performing an HPV auto-test at home. In women 35-69 years the participation to the second invitation to Pap test was significantly lower (7.2%) than the participation to auto-test (26.4%) with Plaw rate is a consequence of an inversion of the ratio HPV 16 versus other types in women 60 years old and over. In this group, the follow-up of 36 women diagnosed five cases of CIN1, one of CIN2 and four of CIN3; 22 patients are lost of follow up at 6 months. Globally, in the studied population, an individual recall for pap test allowed to diagnose and treat 3 high grade lesions (7‰) and the dispatching

    According to the definition by the International Agency for Research on Cancer (IARC), primary multiple neoplasms are two or more neoplasms of different histopathological build in one organ, or two or more tumors occurring in one patient, regardless of the time of their occurrence (synchronic - up to 6 months, metachronous - after 6 months), coming from an organ or a tissue and not being an infiltration from another neoplasm, a relapse or a metastasis. It was the aim of the study to analyze the frequency of the occurrence of multiple neoplasms among patients suffering from uterine cervix cancer, with a special interest in coexistent neoplasms, the time of their occurrence and total 5-year survivals. The data from the Lower Silesian Cancer Registry concerning the years 1984-2009 formed the material of the present study. 5.3% of all cervix neoplasms occurred as multiple cancers. Cervix neoplasms were 13.4% of multiple neoplasms. On average, cervical cancer occurred as a subsequent cancer in 6 patients yearly (60.7% of the occurrences of cervical cancer were in the period of 5 years following treatment for the first neoplasm). 5-year survival in patients suffering from primarily multiple cervix neoplasms constituted 57% and was convergent with the results for all patients suffering from cervical cancer. Cervical cancer as the first neoplasm occurred in 287 patients, on average in 11 patients annually. In the period of the first 5 years after the treatment of cervical cancer, there were 42.8% occurrences of other cancers. Cervical neoplasms most frequently coexisted with cancers of the breast, lung and large intestine. The frequency of the occurrence of multiple neoplasm among cervical cancer patients is increasing. Most frequently they coexist with other tobacco-related neoplasms, those related to HPV infections and with secondary post-radiation neoplasms. These facts should be taken into consideration during post-treatment observation and when directing diagnostic

    Full Text Available Abstract Background Cervical cancer is an important public health problem worldwide, which comprises approximately 12% of all cancers in women. In Tanzania, the estimated incidence rate is 30 to 40 per 100,000 women, indicating a high disease burden. Cervical cancer screening is acknowledged as currently the most effective approach for cervical cancer control, and it is associated with reduced incidence and mortality from the disease. The aim of the study was to identify the most important factors related to the uptake of cervical cancer screening among women in a rural district of Tanzania. Methods A cross sectional study was conducted with a sample of 354 women aged 18 to 69 years residing in Moshi Rural District. A multistage sampling technique was used to randomly select eligible women. A one-hour interview was conducted with each woman in her home. The 17 questions were modified from similar questions used in previous research. Results Less than one quarter (22.6% of the participants had obtained cervical cancer screening. The following characteristics, when examined separately in relation to the uptake of cervical cancer screening service, were significant: husband approval of cervical cancer screening, women's level of education, women's knowledge of cervical cancer and its prevention, women's concerns about embarrassment and pain of screening, women's preference for the sex of health provider, and women's awareness of and distance to cervical cancer screening services. When examined simultaneously in a logistic regression, we found that only knowledge of cervical cancer and its prevention (OR = 8.90, 95%CI = 2.14-16.03 and distance to the facility which provides cervical cancer screening (OR = 3.98, 95%CI = 0.18-5.10 were significantly associated with screening uptake. Conclusions Based on the study findings, three recommendations are made. First, information about cervical cancer must be presented to women. Second, public education of

    Cervical cancer is the second most common cancer in women around the world, and the human papillomavirus (HPV) is universally known as the necessary agent for developing this disease. Through early detection of abnormal cells and HPV virus types, cervical cancer incidents can be reduced and disease progression prevented. We propose a finite-horizon Markov decision process model to determine the optimal screening policies for cervical cancer prevention. The optimal decision is given in terms of when and what type of screening test to be performed on a patient based on her current diagnosis, age, HPV contraction risk, and screening test results. The cost function considers the tradeoff between the cost of prevention and treatment procedures and the risk of taking no action while taking into account a cost assigned to loss of life quality in each state. We apply the model to data collected from a representative sample of 1141 affiliates at a health care provider located in Bogotá, Colombia. To track the disease incidence more effectively and avoid higher cancer rates and future costs, the optimal policies recommend more frequent colposcopies and Pap tests for women with riskier profiles.

    To present a systematic review of papers published on the relationship between violence against women and cervical cancer screening. Violence against women is a serious public health problem. This phenomenon can have negative effects on victims' health and affect the frequency at which they receive cervical cancer screening. A systematic literature review. This study was carried out in October 2015 with searches of the Lilacs, PubMed and Web of Science databases using the following keywords: violence, domestic violence, battered women, spouse abuse, Papanicolaou test, vaginal smears, early detection of cancer and cervix uteri. Eight papers published between 2002-2013 were included in this review, most of which were cross-sectional studies. Three studies found no association between victimisation and receiving Pap testing, and five studies reported an association. These contradictory results were due to higher or lower examination frequencies among the women who had experienced violence. The results of this study indicate that the association between violence against women and cervical cancer screening remains inconclusive, and they demonstrate the need for more detailed studies to help clarify this relationship. Professionals who aid women should be knowledgeable regarding the perception and detection of violence so that they can interrupt the cycle of aggression, which has harmful impacts on victims' health. © 2016 John Wiley & Sons Ltd.

    Locally advanced cervical cancer has a poor prognosis, poor survival rate, and high local failure rate. A number of questions regarding the optimal agents and schedule of concurrent chemoradiation remain unanswered. To improve the cure rate for advanced or recurrent cervix cancer, we studied intra-arterial infusion chemotherapy (IAIC) with or without radiotherapy. We analyzed 52 cases of advanced or recurrent cervical cancer treated by IAIC with or without radiotherapy. IAIC regimen was separated into two groups: group I consisted of 5-FU+MMC{+-}ADM (30 cases) and group II of CDDP+MMC{+-}5-FU (22 cases). The tip of the catheter was placed in the bifurcation of abdominal aorta or the bilateral internal iliac arteries (7 cases). The overall response rate (CR+PR) was 71%, 87% in patients receiving radiotherapy, 50% in those without radiotherapy, and 100% in primary cases. The five-year survival rate was 20% in primary cases, 14% in recurrent cases, 3% in group I and 38% in group II by chemotherapy regimen. Severe (more than grade III) hematological acute side effects were found in 48% of all cases, but recovered by interruption of drugs. In 7 cases in which the tip of the catheter was placed in internal iliac arteries, there were severe skin ulcers in 2 cases and severe pain of leg or gluteal region which need narcotics in 2 cases. These data suggest that IAIC mainly with cisplatin with or without radiotherapy is one of the effective treatments for advanced or recurrent cervical cancer. But we should check blood flow distribution periodically, and control the concentration of drugs. To improve the survival rate for advanced or recurrent cervical cancer, we should discuss neoadjuvant chemotherapy followed by chemoradiotherapy and maintenance systemic chemotherapy. (author)

    Full Text Available Introduction: Cytological examination is a simple and inexpensive method used in the prevention of cervical cancer. In Poland, too low proportions of women still have the test. Aim of the research : To analyse the attitudes towards cervical cancer prevention. Material and methods : Two hundred and ten hospitalized women were invited to take part in the investigation. The research used the diagnostic poll method, using the author’s original questionnaire form. The research was carried out in four gynaecological wards. Results : Of the women who participated in the research, 16.2% by the time of diagnosis had never received a Pap test. In the analysed group, 88.2% of women were not referred to a specialist for a Pap test. Among all respondents, only 35.7% underwent cervix cytology regularly, i.e. once a year or once every 2 years. Conclusions : The effort made by the women towards the attitudes of cervical cancer prevention was insufficient; still too many women had not reported to the specialist for taking material from the cervix, or did not do so regularly. A significant relation in the behaviour of women was found depending on their level of education and place of residence. Greater activity of nurses, midwives and family physicians in stimulating Polish women to participate in prevention programmes for cervical cancer is advisable. To increase the health awareness of girls and women, it is important to include in the curriculum, especially in secondary schools, the issues of prevention of female reproductive system cancer.

    Knowledge of differences in human papillomavirus (HPV)-type prevalence between high-grade cervical intraepithelial neoplasia (HG-CIN) and invasive cervical cancer (ICC) is crucial for understanding the natural history of HPV-infected cervical lesions and the potential impact of HPV vaccination...... on cervical cancer prevention. More than 6,000 women diagnosed with HG-CIN or ICC from 17 European countries were enrolled in two parallel cross-sectional studies (108288/108290). Centralised histopathology review and standardised HPV-DNA typing were applied to formalin-fixed paraffin-embedded cervical...... specimens dated 2001-2008. The pooled prevalence of individual HPV types was estimated using meta-analytic methods. A total of 3,103 women were diagnosed with HG-CIN and a total of 3,162 with ICC (median ages: 34 and 49 years, respectively), of which 98.5 and 91.8% were HPV-positive, respectively. The most...

    Puerto Rico (PR), is the fifth highest jurisdiction of the United States of America (US) with respect to HIV prevalence and the leading in cervical cancer incidence. This cross-sectional study describes the prevalence and correlates of cervical HPV infection among a clinic-based sample of 302 women living with HIV/AIDS in PR. Data collection included questionnaires, blood and cervical samples. Multivariable logistic regression models were used to estimate the magnitude of association (adjusted Prevalence odds ratio [aPOR]) between HPV cervical infection and other covariates. Mean age of participants was 40.3 years (± 10.3SD). The prevalence of HPV infection was 50.3%; 41.1% for low-risk types and 29.5% for high-risk types. Having ≥ 10 lifetime sexual partners (aPOR = 2.10, 95% CI:1.02-4.29), an abnormal Pap (aPOR = 3.58, 95% CI:1.93-6.62), active genital warts (aPOR = 3.45, 95% CI:1.60-7.42), and CD4 counts ≤ 200 (aPOR = 4.24, 95% CI: 1.67-10.78) were positively associated with any cervical HPV infection. Similar results were observed for HR HPV infection. A high burden of HPV co-infection exists among women living with HIV/AIDS in this population. Given the high incidence of HIV in PR and the higher risk of cervical cancer among women living with HIV/AIDS, HPV vaccination should be promoted in this population. Copyright © 2017 The Authors.

    Significantly elevated rates of cervical cancer and low rates of Papanicolaou (Pap) smear screening have been documented among HIV-infected women. However, little is known about women’s perceptions of cervical cancer screening utilization. Hence, this study describes barriers and facilitators related to cervical cancer screening in a sample of HIV-infected women seeking care at an integrated HIV clinic in Houston, Texas. Using an inductive qualitative methodological approach, data were obtained from five focus group discussions with a total of 33, HIV-infected women. The majority of the study sample consisted of women who self-identified as Black (69.7%), and reported heterosexual contact as the mode of HIV acquisition (75.8%). Barriers to cervical cancer screening were described as pain and discomfort associated with receiving Pap smears and subsequent procedures; lack of awareness of cervical cancer as a preventable disease; limited transportation access; and systemic issues as it relates to scheduling gynecological appointments. Facilitators were described as awareness of HIV-infected women’s increased risk of cervical cancer and strong provider-patient relationships. To address disparities in cervical cancer screening among low-income HIV-infected women, programs should capitalize on the identified facilitators and alleviate modifiable barriers using multi-level strategies.

    Cervical cancer is a major health disparity among Asian Americans, with cervical cancer rates of Vietnamese women being significantly higher than for the general US female population and low screening rates reported for Asian American females. Focus groups and interviews were conducted with young Vietnamese, Filipino, and Korean adults (ages 18-29) to collect information on knowledge, perceptions and sources of information regarding cervical cancer, Pap tests and the human papillomavirus. 16 Korean, 18 Vietnamese, and 18 Filipino (50% female) adults participated in the study. Many participants had never heard of HPV, cervical cancer and Pap testing. Cervical cancer screening rates were low for Korean and Vietnamese females and were influenced by moral beliefs and lack of awareness. Culturally relevant education materials that consider specific Asian ethnicity and language are needed to increase awareness of cervical cancer, Pap testing, and HPV among Asian American young adults.

    Screening services for cervical pre-cancerous lesions is currently available for all women aged 30-49 years at public hospitals in Ethiopia. Though women's knowledge and their attitude are determinants for the uptake the screening service, there is limited information on these regards. Therefore, this study aimed to assess comprehensive knowledge on cervical cancer, attitudes towards the screening, and associated factors among women aged 30-49 years at Finote Selam town, northwest Ethiopia. A community based cross-sectional study was conducted from March 30, to April 15, 2017. The sample size calculated for this study was 1224 and a cluster sampling technique was used to select the participants from three randomly selected kebeles. Epi-Info version 7 and Statistical Package for Social Sciences version 20 were used for data entry and analysis respectively. A binary logistic regression model was used. In multivariable logistic analysis, adjusted odds ratio with a 95% confidence interval was used to determine the presence and strength of associations between covariate and outcome variable. A total of 1137 women participated in this study. Nearly one third, 30.3% (95%CI: 27.7, 32.9) of the women had knowledge of cervical cancer, and 58.1% (95% CI: 55, 62.2) had a favorable attitude towards cervical cancer screening. In the multivariable analysis, having college and above education (AOR = 7.21, 95%CI: 3.41, 15.29), knowing someone with cervical cancer (AOR =5.38, 95%CI: 2.38, 12.15), and having a history of sexually transmitted diseases (AOR = 2.75, 95%CI: 1.24, 6.04) were significantly associated with knowledge on cervical cancer. Meanwhile, college and above educational status (AOR = 2.56, 95%CI: 1.14, 5.69), knowing someone with cervical cancer (AOR = 3.24, 95%CI: 1.14, 9.15), and having knowledge of cervical cancer (AOR = 3, 95%CI: 1.97, 4.29) were positively associated with favorable attitudes towards cervical cancer screening.

    To examine the risk factors associated with never being screened for cervical cancer (CC) in Brazil. Using the National Household Sample Survey 2008 (PNAD), we analyzed data from 102,108 Brazilian women ages 25-64years. The patients were analyzed as having been or never having been screened with a Pap smear (Yes/No). Age-adjusted prevalence of never-screening was analyzed using a Chi-squared test. Crude and adjusted models using Poisson regression were performed. The prevalence of never-screened women for CC was 12.9%, 11.5% and 22.2% in Brazil in general, urban and rural areas, respectively. The Brazilian region with the highest prevalence of never-screening was the North (17.4%, 14.7% and 27.3% in general, urban and rural areas, respectively). The factors associated with a higher risk for never being screened were the following: poverty, younger age, lower educational level, non-white skin color, a greater number of children, no supplemental health insurance and not having visited a doctor in the past 12months. Socioeconomic and demographic conditions lead to inequalities in access to Pap smear screening in Brazil. Public health policy addressing these risk groups is necessary. © 2013.
