    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.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

    Curative-intent radical radiotherapy of cervical cancer consists of external-beam radiotherapy, brachytherapy, and concomitant chemotherapy with cisplatin. For each element, new developments aim to improve tumor control rates or treatment tolerance. Intensity-modulated radiotherapy (IMRT) has been shown to reduce gastrointestinal toxicity and can be used to selectively increase the radiotherapy dose. Individualized, image-guided brachytherapy enables better adaptation of high-dose volumes to the tumor extension. Intensification of concomitant or sequential systemic therapy is under evaluation.

    Lynge, Elsebeth; Rygaard, Carsten; Baillet, Miguel Vazquez-Prada;

    2014-01-01

    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...

    2016-06-01

    Despite the development of screening and of a vaccine, cervix cancer is a major cause of cancer death in young women worldwide. A third of women treated for the disease will recur, almost inevitably leading to death. Functional imaging has the potential to stratify patients at higher risk of poor response or relapse by improved delineation of disease extent and tumor characteristics. A number of molecular imaging biomarkers have been shown to predict outcome at baseline and/or early during therapy in cervical cancer. In future this could help tailor the treatment plan which could include selection of patients for close follow up, adjuvant therapy or trial entry for novel agents or adaptive clinical trials. The use of molecular imaging techniques, FDG PET/CT and functional MRI, in staging and response assessment of cervical cancer is reviewed. PMID:26859085

  17. Human papillomavirus testing in cervical cancer screening.

    Castle, Philip E; Cremer, Miriam

    2013-06-01

    Human papillomavirus (HPV) testing is more reliable and sensitive but less specific than Papanicolaou (Pap) testing/cervical cytology for the detection of cervical precancer and cancer. HPV-negative women are at lower risk of cervical cancer than Pap-negative women. In high-resource settings, HPV testing can be used to make cervical cancer prevention programs more efficient by focusing clinical attention on women who have HPV. In lower-resource settings, where Pap testing has not been sustained or widespread, new, lower-cost HPV tests may make cervical cancer screening feasible. PMID:23732037

    2013-01-01

    Full Text Available In case of invasive cervical carcinoma several molecular events were reported and these molecular events resulting in multiple genetic abnormalities. In order to control these tumors multiple molecular therapeutic targets are needed with different molecular mechanisms. Unfortunately, these molecular targets were in early stages of development. Because of less degree of success of conventional therapeutics for late stages of cervical cancer and lowering of prognosis of patients there is an increase in interest for the development of potential therapeutic targets for cervical cancer. This review article emphasizes the current molecular targeted agents; with special attention to estrogen receptors for human papilloma virus infected cervical cancer.

  4. [Cervical cancer screening: past--present--future].

    Breitenecker, G

    2009-12-01

    Despite the undisputed and impressive success which has been achieved since the 1960s by cervical cytology in the fight against cervical cancer and its precursor stages, during which the mortality rate in industrialized countries over the last 40 years has been reduced by two-thirds to three-quarters, a perfect and error-free screening procedure is still a long way off and will probably never be reached. There are two main reasons for this, the lack of adequate coverage and suboptimal quality and assessment of smears. Two screening procedures are in use Europe, an opportunistic and an organized system. Both systems have many advantages but also disadvantages. In organized programs the coverage is higher (up to 80%), although similar numbers are also achieved by non-organized programs over a 3-year cycle, even if they cannot be so exactly documented. The decision on which system is used depends on the health system of the country, public or non-public, and many other national circumstances. However, in both systems prerequisites for a satisfactory result is a high quality in the sampling technique, the processing and the assessment. Therefore, several guidelines have been introduced by state and medical societies for internal and external quality assurance. New technologies, such as thin-layer cytology or automation for replacement or support of conventional cytology liquid-based cytology proved not to be superior enough to justify the high costs of these systems. The recognition of the strong causal relationship between persistent infection with high-risk human papillomavirus (HPV) types and cervical cancer and its precursors has resulted in the development of comparably simple tests. Primary screening using HPV typing alone is not recommended in opportunistic screening due to the low specificity but high sensitivity because it leads to many clinically irrelevant results which place women under stress. In organized screening HPV testing is always and only possible

    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

  8. Immunosuppression and risk of cervical cancer

    Peralta-Zaragoza, Oscar; Bermúdez-Morales, Víctor Hugo; Pérez-Plasencia, Carlos; Salazar-León, Jonathan; Gómez-Cerón, Claudia; Madrid-Marina, Vicente

    2012-01-01

    Cervical cancer is the second most common cause of cancer death in women worldwide and the development of new diagnosis, prognostic, and treatment strategies merits special attention. 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.

    2015-01-01

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

  17. Radiosensitizers in cervical cancer. Cisplatin and beyond

    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

    BACKGROUND: Due to its extraordinarily fast economic and social transition, virtually closed borders before 1940 and, moreover, that 85% of the population has the distinctive genetics of the Inuit, Greenland is a very interesting country to study cervical cancer from a historical perspective....... Nevertheless, little has been reported about long-term cancer trends in Greenland. Our aim was to describe and interpret the incidence of cervical cancer from 1950 to 2009. MATERIAL AND METHODS: We systematically searched PubMed for articles reporting the incidence of cervical cancer in Greenland. We...... supplemented this with data for 1980-2009 obtained from the Chief Medical Officer of Greenland. RESULTS: Incidence of cervical cancer was around 10 per 100 000 women (age-standardised, world population, ASW) in the 1950s, 30 per 100 000 in the 1960s, and in the 1980s around 60 per 100 000.

    Full Text Available Fertility can be preserved after conservative cervical surgery. We report on a 29-year-old woman who was obese, para 0, and diagnosed with cervical insufficiency at the first trimester of current pregnancy due to a previous trachelectomy. She underwent laparoscopic transabdominal cervical cerclage (LTCC for cervical cancer. The surgery was successful and she was discharged two days later. The patient underwent a caesarean section at 38 weeks of gestation. Laparoscopic surgery is a minimally invasive approach associated with less pain and faster recovery, feasible even in obese women.

  2. Epidemiology of cervical cancer in Colombia

    Muñoz, Nubia

    2012-12-01

    Full Text Available Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence of screening programs during the last 3 decades. Bucaramanga, Manizales and Cali reported rates around 20 per 100,000 and Pasto 27 per 100,000. The Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline in incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs.Human papilloma Virus is the main cause of cervical cancer, HPV natural history studies have now revealed that HPVs are the commonest of the sexually transmitted infec¬tions in most populations. Most HPV exposures result in sponta¬neous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancerous and cancer. HPV 16 and 18 account for 70% of cervical cancer and the 8 most common types. (HPV 16, 18, 45, 33, 31, 52, 58 and 35 account for about 90% of cervical cancer. Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. The demonstration that infection with certain types of human papillomavirus (HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two fronts: (i Primary prevention by the use of

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

  4. Epidemiology and Early Detection of Cervical Cancer.

    2016-01-01

    The new German S3 guideline 'Prevention of Cervical Cancer' published in 2016 is based on the latest available evidence about cervical cancer screening and treatment of cervical precancer. Large randomized controlled trials indicate that human papillomavirus (HPV)-based screening may provide better protection against cervical cancer than cytology alone through improved detection of premalignant disease in the first screening round prior to progression. Therefore, women aged 30 years and older should preferably be screened with HPV testing every 3-5 years (cytology alone every 2 years is an acceptable alternative). Co-testing is not recommended. Screening should start at 25 years using cytology alone every 2 years. The preferred triage test after a positive HPV screening test is cytology. Women positive for HPV 16 and HPV 18 should receive immediate colposcopy. Another alternative triage method is p16/Ki-67 dual stain cytology. The mean yearly participation rate in Germany is between 45 and 50%. Offering devices for HPV self-sampling has the potential to increase participation rates in those women who are at higher risk of developing cervical cancer. Regarding primary prevention, the 9-valent vaccine may provide protection against up to 85% of cervical intraepithelial neoplasia (CIN) 3 and 90% of cervical cancer, and is available in Europe as a 2-dose schedule from May 2016.

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

Major advances but still insufficient achievements in the treatment of locally advanced and high-risk early stage patients have occurred in the last decade with the incorporation of concurrent cisplatin with radiation and, lately, gemcitabine added to cisplatin chemoradiation. Despite a number of clinical studies incorporating molecular-targeted therapy as radiosensitizers being in progress, so far, only antiangiogenic therapy with bevacizumab added to cisplatin chemoradiation has demonstrated safety and shown encouraging results in a Phase II study. In advanced disease, cisplatin doublets do not have a great impact on the natural history of the disease with median survival rates not exceeding 13 months. The first Phase III study of bevacizumab, added to cisplatin or a non-cisplatin-containing doublet, showed significant increase in both overall survival and progression-free survival. Further studies are needed before bevacizumab plus chemotherapy can be considered the standard of care for advanced disease. Characterization of the mutational landscape of cervical cancer has already been initiated, indicating that, for now, few of these targetable alterations match with available agents. Progress in both the mutational landscape knowledge and developments of novel targeted therapies may result in more effective and individualized treatments for cervical cancer.

  8. Effects of irradiation for cervical cancer on subsequent breast cancer

    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

  12. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Joeli A. Brinkman

    2007-01-01

    Full Text Available 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.

  13. Epidemiology and biology of cervical cancer.

    Schoell, W M; Janicek, M F; Mirhashemi, R

    1999-01-01

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    Full Text Available Background: Although preventable, cervical cancer, an AIDS-related disease, is the second most common cancer amongst South African women and the most common cancer amongst black women. 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. Cervical cancer: Can it be prevented?

    Aggarwal, Pakhee

    2014-10-10

    Cervical cancer prevention requires a multipronged approach involving primary, secondary and tertiary prevention. The key element under primary prevention is human papilloma virus (HPV) vaccination. So far, only prophylactic HPV vaccines which prevent HPV infection by one or more subtypes are commercially available. Therapeutic HPV vaccines which aid in clearing established infection are still under trial. Secondary prevention entails early detection of precancerous lesions and its success is determined by the population coverage and the efficacy of the screening technique. A number of techniques are in use, including cytology, visual inspection (using the naked eye, magnivisualizer, acetic acid and Lugol's iodine), HPV testing and a combination of these methods. Updated screening guidelines have been advocated by the American Cancer Society in light of the role of HPV on cervical carcinogenesis. Recent research has also focussed on novel biomarkers that can predict progression to cancer in screen positive women and help to differentiate those who need treatment from those who can be left for follow-up. Last but not the least, effective treatment of precancerous lesions can help to reduce the incidence of invasive cervical cancer and this constitutes tertiary prevention. A combination of these approaches can help to prevent the burden of cervical cancer and its antecedent morbidity and mortality, but all of these are not feasible in all settings due to resource and allocation constraints. Thus, all countries, especially low and middle income ones, have to determine their own cocktail of approaches that work before we can say with certainty that yes, cervical cancer can be prevented.

    Full Text Available Invasive cervical carcinoma usually reaches its highest frequency between 35-50 years of age. The Cuban prevention program screens the female population aged 25 to 60 years using the Pap smear and reexamines them every three years. Despite this effort, advanced cancer is diagnosed in young women as well as in those 40 to 60 years of age.

    Cancer has the potential to provoke worries which should be assessed in order to adequately respond to patients' problems. We highlight in this paper the problems that concerned 30 women with cervical cancer (mean age 51.2) and 76 with breast cancer (mean age 44.9), how these concerns affected their emotional lives, and the factors associated with these worries. They were interviewed with the 33-item modified version of a German questionnaire rating psychosocial concerns (FBS) by Sullwold, and Goldberg's General Health Questionnaire (GHQ-12) for psychopathological symptoms. Cervical cancer patients had significantly higher FBS and GHQ-12 scores than breast cancer. Breast cancer cases had FBS scores similar to those of women with sickle cell disease and insulin-dependent diabetes mellitus. The commonest recurrent worries in both groups were depression about their condition (45%), thoughts of death (37%), insomnia (33.3%), bodily odour (30%), impairment of work efficiency (30%) terrifying dreams (27%) and fear of illness being life-long (25%). Over 90% denied experience of worries indicating social stigma. FBS scores were significantly correlated with GHQ scores and both were negatively associated with adequacy of social contacts. These data suggest the need for psychosocial intervention in such cases in Nigeria. PMID:9885090

    Full Text Available Sharron SK Leung1, Ivy Leung21School of Nursing, Li Ka Shing Faculty of Medicine, The University of Hong Kong; 2Quality Healthcare Medical Services, Hong KongPurpose: Cervical cancer screening has been consistently shown to be effective in reducing the incidence rate and mortality from cervical cancer. However, cervical screening attendance rates are still far from satisfactory in many countries. Strategies, health promotion and education programs need to be developed with clear evidence of the causes and factors relating to the low attendance rate. The study aims to assess the prediction of cervical screening attendance rate by Chinese women’s knowledge about cervical cancer and cervical screening as well as their perception of health.Patients and methods: A survey with self-reported questionnaires was conducted on 385 Chinese women recruited from a community clinic in Hong Kong. Participants were Chinese women, Hong Kong residents, aged 18–65 years, able to read Chinese or English, and were not pregnant.Results: Women aged 37 years or less, with at least tertiary education, who perceived having control over their own health and had better knowledge on risk factors, were more likely to attend cervical cancer screening. Many participants had adequate general knowledge but were unable to identify correct answers on the risk factors.Conclusion: Health promotion efforts need to focus on increasing women’s knowledge on risk factors and enhancing their perceived health control by providing more information on the link between screening and early detection with lower incidence rates and mortality from cervical cancer.Keywords: cervical screening attendance, cervical cancer, health perception and knowledge, perceived health control, Chinese

    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 ...

    1997-07-01

    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.El potencial uso de vacunas de virus del papiloma humano (VPH en la prevención y tratamiento del cáncer cervical posiblemente será implementado durante los próximos años. Cerca de los 20 genotipos de VPH de los 75 que se encuentran identificados infectan el tracto genital femenino, pero son cuatro subtipos: 16, 18, 31 y 45 los que se han asociado en cerca de 80% a cáncer cervical. En este ensayo se plantea que para poder diseñar una vacuna profiláctica contra la infección de VPH, efectiva, se debe garantizar una adecuada respuesta inmune a través de cuatro metas: a activación de antígenos presentes en la célula; b superar la respuesta del huésped y la variabilidad genética viral en la respuesta de células T; c generación de altos niveles de células T y B de memoria, y d persistencia de antígenos.

    Objective:To measure the expression pattern ofSTAT2 in cervical cancer initiation and progression in tissue sections from patients with cervicitis, dysplasia, and cervical cancer. Methods:Antibody against humanSTAT2 was confirmed by plasmids transient transfection andWestern blot.Immunohistochemistry was used to detectSTAT2 expression in the cervical biopsies by using the confirmed antibody againstSTAT2 as the primary antibody.Results:It was found that the overall rate of positiveSTAT2 expression in the cervicitis, dysplasia and cervical cancer groups were38.5%,69.4% and76.9%, respectively.TheSTAT2 levels are significantly increased in premalignant dysplasia and cervical cancer, as compared to cervicitis(P<0.05). Noticeably,STAT2 signals were mainly found in the cytoplasm, implying thatSTAT2 was not biologically active.Conclusions:These findings reveal an association between cervical cancer progression and augmentedSTAT2 expression.In conclusion,STAT2 increase appears to be an early detectable cellular event in cervical cancer development.

  7. The male role in cervical cancer

    Castellsagué Xavier

    2003-01-01

    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.

  8. Cervical cancer: evaluation of our results

    Introduction: Cervical cancer in women occupies 3rd place in incidence and 5th as a cause of cancer death in our country. The evolution is mainly determined by the stage, nodal status and histological type. The treatment of these tumors is surgical, radiant and / or systemic, depending on your choice mainly Stadium. Objective: To analyze the characteristics, evolution, treatment and survival of patients carriers of cervical cancer. Patients and Methods: The medical records were retrospectively analyzed for patients with cervical cancer treated at the Department of Oncology the Clinical Hospital in the period 1994-2004. Curves were constructed survival (sv) of total and free enfemedad sv sv by stage and after relapse by the method of Kaplan-Meier. Results: n = 75 patients, median age 45 years (24-90 years). Histological type: Epidermoid carcinomas 93% 5% 2% adenocarcinomas and adenosquamous. stadium (E) Initial: 31% IE, 38% EII, EIII 25%, 6% EIVA. Treatment was according to the stadium, considering that until 1999 was not standard concurrent chemoradiation. The median sv considering all stages was 124 months. The sv to 5 years for EI was 90% (median 188 sv months), for the ISI 65% (95 months) and the median sv CIRTs was 24 months. Followed for 13 months, 12 patients relapsed and the median after sv relapse was 8 months (95% CI 4-13 months) Conclusions: Although cervical cancer is a preventable disease, remains an important cause of morbidity and mortality. Our results are consistent with those reported in the literature, however far from the optimal, so it is necessary to continue clinical trials in this regard

  9. Cervical cancer awareness and risk factors among female university students.

    Buga, G A

    1998-07-01

    Population cervical screening programmes are necessary for meaningfully reducing cervical cancer morbidity and mortality. Because of the high incidence of cervical cancer in South Africa, the need for a national screening programme has become evident. The success of such a programme will depend on, among others, the level of cervical cancer awareness among the target population, and their willingness to utilise cytological services and to comply with treatment and follow up protocols. We conducted a survey among female university students, as an elite group of women, to determine their level of cervical cancer awareness and the prevalence of the major risk factors for cervical cancer among them, their rate of utilisation of existing Pap smear services, and their attitudes to Pap smears in general. The majority of respondents were young, single (93.0%) and sexually active (86.9%,) having initiated sexual activity at a mean age of 17.27 +/- 2.18 years. There was a high prevalence of the major risk factors for cervical cancer among the respondents, and these included initiation of coitus before 18 years (53.3%), multiple sexual partners (73.6%), male partner with other partners (37.7%), and previous history of sexually transmitted diseases (42.2%) and vulval warts (4.7%). Their overall knowledge of cervical cancer was poor, although the majority of respondents were able to identify the major risk factors from a given list. This level of awareness of cervical cancer risk factors, however, did not translate into appreciation of personal risk of cervical cancer, safer sex practices or utilisation of Pap smear services. In conclusion, this elite group of women is at a high risk of cervical cancer and would benefit from cervical screening programmes. This would have to be coupled with measures to increase the level of awareness and knowledge of cervical cancer and its prevention. PMID:9803633

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

    Full Text Available Objective. Vietnamese American women are at the greatest risk for cervical cancer but have the lowest cervical cancer screening rates. This study was to determine whether demographic and acculturation, healthcare access, and knowledge and beliefs are associated with a prior history of cervical cancer screening among Vietnamese women. Methods. Vietnamese women (n=1450 from 30 Vietnamese community-based organizations located in Pennsylvania and New Jersey participated in the study and completed baseline assessments. Logistic regression analyses were performed. Results. Overall levels of knowledge about cervical cancer screening and human papillomavirus (HPV are low. Factors in knowledge, attitude, and beliefs domains were significantly associated with Pap test behavior. In multivariate analyses, physician recommendation for screening and having health insurance were positively associated with prior screening. Conclusion. Understanding the factors that are associated with cervical cancer screening will inform the development of culturally appropriate intervention strategies that would potentially lead to increasing cervical cancer screening rates among Vietnamese women.

  16. New paradigms in cervical cancer prevention: opportunities and risks

    Giorgi Rossi Paolo

    2008-12-01

    Full Text Available Testing for the DNA of high-risk types of papilloma virus (HPV is more sensitive than cytology in detecting pre-cancerous lesions. One of the main advantages will be the possibility of applying prolonged screening intervals. However adequate screening protocols (age of start and stop, screening intervals, management of HPV positive women need to be applied in order to avoid over-referral to colposcopy and over-treatment and to maintain sustainable costs. Further follow-up of running trials and research on molecular markers will better define these parameters. The new situation will require organised screening programmes with rigorous protocols and monitoring. This will be even more needed when women vaccinated for HPV 16 and 18 will be screened. Research on how to best screen vaccinated women is a priority. This paper proposes an overview of the plausible impact of new technologies in cervical cancer screening in the near future and in the vaccinated cohorts.

The study was performed on a number of 1249 patients who were suspected of having cervical neoplasia, and who were monitored between 2006-2010 in „Elena-Doamna” Clinical Hospital of Obstetrics and Gynecology in Ia�i, the Military Hospital Gala�i, the County Hospital Gala�i and the Emergency Hospital Buzau. Results and discussions. The study proved the effectiveness of the conservative treatment for the patients who were diagnosed using cytology, colposcopy, biopsy and histopathology, with or without HPV viral infection. Conclusions. The patients with an early diagnose have a 15% higher surviving probability. The patients who responded to the conservative preoperative treatment well are more likely to survive than the patients who did not respond favourably to the conservative preoperative treatment.

  1. Dosimetrically Triggered Adaptive Intensity Modulated Radiation Therapy for Cervical Cancer

    Purpose: The widespread use of intensity modulated radiation therapy (IMRT) for cervical cancer has been limited by internal target and normal tissue motion. Such motion increases the risk of underdosing the target, especially as planning margins are reduced in an effort to reduce toxicity. This study explored 2 adaptive strategies to mitigate this risk and proposes a new, automated method that minimizes replanning workload. Methods and Materials: Thirty patients with cervical cancer participated in a prospective clinical study and underwent pretreatment and weekly magnetic resonance (MR) scans over a 5-week course of daily external beam radiation therapy. Target volumes and organs at risk (OARs) were contoured on each of the scans. Deformable image registration was used to model the accumulated dose (the real dose delivered to the target and OARs) for 2 adaptive replanning scenarios that assumed a very small PTV margin of only 3 mm to account for setup and internal interfractional motion: (1) a preprogrammed, anatomy-driven midtreatment replan (A-IMRT); and (2) a dosimetry-triggered replan driven by target dose accumulation over time (D-IMRT). Results: Across all 30 patients, clinically relevant target dose thresholds failed for 8 patients (27%) if 3-mm margins were used without replanning. A-IMRT failed in only 3 patients and also yielded an additional small reduction in OAR doses at the cost of 30 replans. D-IMRT assured adequate target coverage in all patients, with only 23 replans in 16 patients. Conclusions: A novel, dosimetry-triggered adaptive IMRT strategy for patients with cervical cancer can minimize the risk of target underdosing in the setting of very small margins and substantial interfractional motion while minimizing programmatic workload and cost

  3. Understanding cervical cancer in the context of developing countries

    2012-01-01

    Full Text Available Cancer is one of the leading causes of deaths worldwide. Among the women, gynecological cancers are most common. Cervical cancer is a main gynecological cancer of the women. The global burden of cervical cancer is disproportionately high among the developing countries where 85 per cent of the estimated 493, 000 new cases and 273, 000 deaths occur worldwide. There are several dimensions of the problem. Cervical cancer is a problem where people are poor, where the socio-economic status of the women is low and sometimes specific ethnicity also posses additional risk to the women to develop cervical cancer. Human papillomavirus infection is a main risk factor for the cervical cancer however there are some other factors which increase the risk. Among them some are number of sexual partners, age of first sexual intercourse, infection of sexually transmitted diseases, use of hormonal contraceptives, parity, age, smoking, food and diet. Apart from these factors, some other issues, such as policy on cancer, capacity of health system, socio-economic and cultural factors and awareness among the women are also associated with the cervical cancer related morbidity and mortality across the developing countries. There some interventions which give promising results in terms of reducing cervical cancer related morbidity and mortality. Among them visual inspection of cervix with acetic acid followed by treatment is one such effective method.

  4. Cancer risk following radiotherapy of cervical cancer: A preliminary report

    Women treated for cervical cancer were selected for study because (a) doses to body organs following radiotherapy can be accurately determined and vary sufficiently to permit dose-response evaluations, (b) organs remote from the cervix receive low-dose exposures in the range of current scientific interest, (c) treatment is relatively successful and many patients survive long enough to be at risk of late complications of radiotherapy, and (d) several nonexposed groups of women with cervical cancer are also available for comparison. In addition, population-based cancer registries provide an opportunity to inexpensively study large numbers of individuals over many decades. The careful procedures normally used by cancer registries to record second primary cancers facilitate the study of cancer incidence for which a wider view of radiation risk is expected than can be seen in investigations of mortality. Other special features of studies of cervical cancer patients include the ability to assess the effects of very large partial-body exposures, differences in organ sensitivities to radiation, interactions of radiation with biological factors such as age, and the duration of carcinogenic response

    2010-01-01

    In the absence of any nationwide cervical screening program, cancer of cervix remains a major public health problem for India. We here assessed knowledge levels of female college students about cervical cancer, its risk factors, the human papillomavirus (HPV) etiologic agent and Pap (Papanicolaou) smear testing for screening. We conducted a questionnaire survey of the students (N=630), aged 17 to 24 years, in Kolkata, India. Only 20% correctly identified cervix cancer as the most prevalent female cancer in India, while 43% were aware of the ages of occurrence. Though 41% thought sexual activity to be associated with cervical cancer, its risk factors, like, smoking, having multiple sex partners, cervical infections, early onset of sexual intercourse, multiple parity were recognized by 29%, 3%, 4%, 13% and 15%, respectively. The terms Pap test and HPV had been heard by 11% and 15 % of the students, respectively, and 75% of the students desired to have protective vaccination. Bivariate analysis revealed that educational stream, standard of the college and family size were significantly associated with knowledge levels. Additionally, multivariate regression analysis indicated city students were more knowledgeable than those from outside the city. It is imperative that women gather adequate knowledge on cervical cancer for the success of any program to control the disease. Wide and effective spreading of awareness about the disease among women must form an integral part of public health policy of government. PMID:21133629

    OBJECTIVE To investigate the putative role of the Notch1 receptor in cervical cancer carcinogenesis and progression.METHODS The expression of the Notch1 protein was analyzed by a Western-blotting approach in 40 cervical cancer and 30 normal cervical tissues.Some tissues were examined using RT-PCR To determine Mrna levels.Celluar localization of the Notch1 protein in the paraffin-embedded cervical tissues was also analyzed by immunohistochemistry.RESULTS The Notch1 protein was detected in all 30 normal cervical tissues.In contrast.only 6 samples of 40 cervical cancer tissues showed Notch1 expression.The level of the Notch1 protein expression was significantly lower in cervical cancer tissues than that in normal tissue samples.In agreement with these observations.levels of Notch1 Mrna were found to be substantially down-regulated in cervical cancer tissues.In the immunohistochemistry staining assay,the Notch1 protein was shown to localize predominantly in the cytoplasm and nucleoli of the normal cervical squamous epithelium of the cervix,but no staining was observed in the cervical cancer cells.Notch1 expression was observed to correlate with the clinical disease stage.but there were no correlations with age,tumor size,grade or lymph node metastasis (P>0.05).The levels of Notchl protein expression were significantly higher in early stages(I~lla,66.7%) compared to those in the advanced stages (Iib~IV,12.6%)(P=0.001).CONCLUSION Notch1 may play a role as a tumor suppressor in cervical tumorigenesis.Determination of Notch1 expression may be helpful for preoperative diagnosis and accuracy of staging.But its clinical use for cervical cancer requires further investigation.

  11. [Gene therapy with cytokines against cervical cancer].

    Bermúdez-Morales, Victor Hugo; Peralta-Zaragoza, Oscar; Madrid-Marina, Vicente

    2005-01-01

    Gene therapy is an excellent alternative for treatment of many diseases. Capacity to manipulate the DNA has allowed direct the gene therapy to correct the function of an altered gene, to increase the expression of a gene and to favour the activation of the immune response. This way, it can intend the use of the DNA like medication able to control, to correct or to cure many diseases. Gene therapy against cancer has an enormous potential, and actually the use of the DNA has increased to control diverse cancer in animal models, with very encouraging results that have allowed its applications in experimental protocols in human. This work concentrates a review of the foundations of the gene therapy and its application on cervical cancer, from the point of view of the alterations of the immune system focused on the tumour micro-environment, and the use of the cytokines as immunomodulators.

  12. Common filaggrin gene mutations and risk of cervical cancer

    Bager, Peter; Wohlfahrt, Jan; Sørensen, Erik;

    2015-01-01

    BACKGROUND: As carriers of filaggrin gene (FLG) mutations may have a compromised cervical mucosal barrier against human papillomavirus infection, our primary objective was to study their risk of cervical cancer. METHODS: We genotyped 586 cervical cancer patients for the two most common FLG...... mutations, R501X and 2282del4, using blood from the Copenhagen Hospital Biobank, Denmark. Controls (n = 8050) were genotyped in previous population-based studies. Information on cervical cancer, mortality and emigration were obtained from national registers. Odds ratios (OR) were estimated by logistic...... and stratification by cancer stage. RESULTS: The primary results showed that FLG mutations were not associated with the risk of cervical cancer (6.3% of cases and 7.7% of controls were carriers; OR adjusted 0.81, 95% CI 0.57-1.14; OR adjusted+ weighted 0.96, 95% CI 0.58-1.57).

    2014-05-01

    This study was undertaken to investigate the mitochondrial DNA (mtDNA) variation in non-malignant and malignant cervical tissue samples. We have identified 229 and 739 variations non-malignant and malignant tissues respectively distributed over 321 locations in the D-loop (50 in non-malignant and 166 in malignant; 216 variations), coding region (139 in non-malignant and 455 in malignant; 594 variations) tRNA and rRNA genes (39 in non-malignant and 119 in malignant; 158 variations). Besides, 77 novel and 34 various other disease associated variations were identified in non-malignant and malignant samples. A total of 236 tumor specific variations in 201 locations representing 30.1% in D-loop, 59.3% in coding regions and 10.6% in RNA genes were also identified. Our study shows that D loop (in 67 locations) is highly altered followed by ND5 (35 locations) region. Moreover, mtDNA alterations were significantly higher in malignant samples by two tailed Fisher's exact test (P≤0.05) with decreased mtDNA copy numbers. Bioinformatic analysis of 59 non-synonymous changes predicted several variations as damaging leading to decreased stability of the proteins. Taken together, mtDNA is highly altered in cervical cancer and functional studies are needed to be investigated to understand the consequence of these variations in cervical carcinogenesis and their potential application as biomarkers.

  20. Neoadjuvant chemotherapy in cervical cancer in pregnancy.

    Ilancheran, Arunachalam

    2016-05-01

    Cervical cancer is the most common gynecological cancer encountered in pregnancy. The standard treatment of early cervical cancer is usually surgical removal of the cervix (in selected cases) or, more commonly, the uterus. However, when cervical cancer develops during pregnancy, definitive surgical treatment often needs to be postponed until the fetus reaches maturity. Neoadjuvant chemotherapy (NACT) is an innovative approach in the management of these patients. It helps in controlling the disease and delaying delivery. The paper presents a literature review of the history of NACT, as well as practice points and agenda for further research. PMID:26536815

    2013-11-01

    Full Text Available Poland is one of the countries with high cervical cancer morbidity and mortality. The main means to change this situation is to manage an active and modern programme of cervical cancer prophylaxis and diagnostics. To a large extent, the effectiveness of a cervical cancer prophylaxis programme is decided by the availability of modern diagnostic research. The conventional Papanicolaou test and modern LBC cytology techniques were discussed in the article, taking into consideration HPV diagnostics in the procedures for carefully selected cytological diagnosis, in the so called in-depth stage of preventive screening tests and the role of the p16 biomarker in predicting the development of a higher degree of epithelial-cell pathologies of the cervix. Colposcopy as a diagnostic method for the verification of cytological and virological abnormalities. The modern LEEP/LLETZ procedure used in diagnosis and treatment of cervical changes is used to realise the in-depth stage of cervical cancer prophylaxis programmes.

    2016-01-01

    Abstract As whether Chlamydia trachomatis infection increases the risk of cervical cancer is controversial in the literature, we performed a meta-analysis. Based on a comprehensive search of publications in the Medline, Cochrane, and EMBASE databases, we identified and extracted data from all relevant articles examining C. trachomatis infection and the risk of cervical cancer. The quality of each included study was assessed according to the 9-star Newcastle–Ottawa scale. The strength of association between the C. trachomatis and risk of cervical cancer was estimated by odds ratio (OR) and 95% confidence intervals (CIs). This review was registered at PROSPERO with registration No. CRD42014015672. A total of 22 studies with 4291 cervical cancer cases and 7628 controls were identified. Overall, C. trachomatis was significantly linked to increased cervical cancer risk in prospective studies (OR = 2.21, 95% CI: 1.88–2.61, P papilloma virus and C. trachomatis has a higher risk of cervical cancer (OR = 4.03, 95% CI: 3.15–5.16, P papilloma virus infections. This approach will not only protect against pelvic inflammatory disease and infertility, but may also prevent cervical cancer. PMID:27043670

    2016-01-01

    Full Text Available Background: Cervical cancer is the third most common cancer worldwide. Accurate information about cervical cancer to general public can lower the burden of the disease including its mortality. Aims: We aimed to look at the quality of information available in YouTube for cervical cancer. Materials and Methods: We searched YouTube (http://www.youtube.com for videos using the keyword "Cervical cancer" on November 12, 2015. Videos were then analyzed for their source and content of information. Results: We studied 172 videos using the keyword "Cervical cancer" on November 12, 2015. We found that there were videos describing the personal stories, risk factors, and the importance of screening. However, videos discussing all the aspects of cancers were lacking. Likewise, videos from the reputed organization were also lacking. Conclusion: Although there were numerous videos available in cervical cancer, videos from reputed organizations including Center for Disease Control and Prevention, American Cancer Society, and World Health Organization were lacking. We strongly believe that quality videos from such organizations via YouTube can help lower the burden of disease.

    2013-07-01

    The aim of this study was to determine the frequency of abnormal cervical cytology in preoperative cervical cytology of patients diagnosed with uterine papillary serous carcinoma (UPSC) and endometrioid endometrial carcinoma (EEC). In addition, associations between abnormal cervical cytology and clinicopathologic factors were evaluated. In this multicentre study, EEC patients diagnosed at two hospitals from 1999 to 2009 and UPSC patients diagnosed at five hospitals from 1992 to 2009, were included. Revision of the histologic slides was performed systematically and independently by 3 gynecopathologists. Cervical cytology within six months before histopathologic diagnosis of endometrial carcinoma was available for 267 EEC and 80 UPSC patients. Cervical cytology with atypical, malignant, or normal endometrial cells in postmenopausal women was considered as abnormal cytology, specific for endometrial pathology. Abnormal cervical cytology was found in 87.5% of UPSC patients, compared with 37.8% in EEC patients. In UPSC, abnormal cytology was associated with extrauterine spread of disease (P=0.043). In EEC, abnormal cytology was associated with cervical involvement (P=0.034). In both EEC and UPSC patients, abnormal cervical cytology was not associated with survival. In conclusion, abnormal cervical cytology was more frequently found in UPSC patients. It was associated with extrauterine disease in UPSC patients, and with cervical involvement in EEC patients. More prospective research should be performed to assess the true clinical value of preoperative cervical cytology in endometrial cancer patients. PMID:23722512

  15. Chromosomal instability as a prognostic marker in cervical cancer

    Cervical cancer is the third most common cancer in women globally, and despite treatment, distant metastasis and nodal recurrence will still develop in approximately 30% of patients. The ability to predict which patients are likely to experience distant relapse would allow clinicians to better tailor treatment. Previous studies have investigated the role of chromosomal instability (CIN) in cancer, which can promote tumour initiation and growth; a hallmark of human malignancies. In this study, we sought to examine the published CIN70 gene signature in a cohort of cervical cancer patients treated at the Princess Margaret (PM) Cancer Centre and an independent cohort of The Cancer Genome Atlas (TCGA) cervical cancer patients, to determine if this CIN signature associated with patient outcome. Cervical cancer samples were collected from 79 patients, treated between 2000–2007 at the PM, prior to undergoing curative chemo-radiation. Total RNA was extracted from each patient sample and analyzed using the GeneChip Human Genome U133 Plus 2.0 array (Affymetrix). High CIN70 scores were significantly related to increased chromosomal alterations in TCGA cervical cancer patients, including a higher percentage of genome altered and a higher number of copy number alterations. In addition, this same CIN70 signature was shown to be predictive of para-aortic nodal relapse in the PM Cancer Centre cohort. These findings demonstrate that chromosomal instability plays an important role in cervical cancer, and is significantly associated with patient outcome. For the first time, this CIN70 gene signature provided prognostic value for patients with cervical cancer

  16. Cervical cancer in Indigenous women: The case of Australia.

    Shannon, Geordan D; Franco, Oscar H; Powles, John; Leng, Yue; Pashayan, Nora

    2011-11-01

    Globally, health inequities between Indigenous and non-Indigenous populations exist. The disparity in health outcomes between Indigenous and non-Indigenous Australians is exemplified by cervical cancer. Current evidence suggests that Indigenous women have higher age standardised incidence and mortality than non-Indigenous women when adjusted for stage at diagnosis and co-morbidities; however, there is little information pertaining to national estimates of cervical cancer in Indigenous women. In this paper we review available evidence on the difference in occurrence and case fatality of cervical cancer among Indigenous and non-Indigenous Australian women. The Australian Bureau of Statistics, Australian Institute of Health and Welfare, and State- or Territory-based Cancer Registries were utilised to collect surveillance data. To corroborate existing data, further available journal literature was identified through Medline and Embase. All papers selected for review were cross-referenced to identify further relevant studies. The most recent national estimate of age-standardised cervical cancer incidence rate was 16.9 and 7.1 per 100,000 women-years in Indigenous and non-Indigenous women respectively (incidence ratio 2.4). The Indigenous age-standardised mortality rate was 9.9 per 100,000 women years (95% CI 7.1-13.3), over 5 times the non-Indigenous rate. Cervical cancer incidence, in both Indigenous and non-Indigenous women, has decreased since 1991. Despite the decline, age-standardised incidence among Indigenous women is still higher than non-Indigenous women. The pattern of cervical cancer incidence and survival corroborates the health inequities that exist in Australia. Indigenous women are more likely than non-Indigenous women to develop cervical cancer and are less likely to survive it. Similar patterns exist in Indigenous populations worldwide, such as New Zealander Maoris and Canadian Aboriginals, suggesting that high rates of cervical cancer incidence and

  17. Cervical cancer: The preventive role of HPV vaccine (review article

    2007-05-01

    Full Text Available Cervical cancer is the second most common gynecologic cancer. A steady 70% annual decline in mortality from cervical cancers has been observed since the mid 20th century after the introduction of widespread papanicolaou cytological screening. But also cervical cancer continues to be an important world health problem for women. Cervical cancer is one of the best- understood neoplasm given its well known viral cause of persistent infection with high risk human papillomavirus (HPV. To date, two manufacturers have developed HPV vaccines composed of noninfectious, recombinant HPV viral-like particles (VLPs. This article presents current advances and perspectives on HPV vaccines.The vaccine is administered by intramuscular injection, and the recommended schedule is a 3-dose series with the second and third doses administered 2 and 6 months after the first dose. The recommended age for vaccination of females is 11-12 years. Vaccine can be administered as young as age 9 years. Catch-up vaccination is recommended for females aged 13--26 years who have not been previously vaccinated. Vaccination is not a substitute for routine cervical cancer screening, and vaccinated females should have cervical cancer screening as recommended.

  18. A review of cervical cancer research in malaysia.

    Zaridah, S

    2014-08-01

    Despite cervical cancer being potentially preventable, it is the second most common cancer among women in Malaysia. One hundred and five articles related to Cervical Cancer were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. Fifty seven articles were selected and reviewed for the articles' clinical relevance and future research implications. This article reviews the various aspects of cervical cancer in Malaysia, mainly persistent infection of high risk human papillomavirus (HPV), primary prevention (HPV vaccination), screening method (Pap smear issues), and the attitude and knowledge of various groups of Malaysian women that contributed to the failure to reduce the incidence and mortality of cervical cancer. Most of the studies focused on prevention, Pap smear issues, HPV DNA testing, HPV vaccination and various recommendations for prevention of cervical cancer. Secondary prevention by screening is still an important aspect because even with HPV vaccination, screening still plays an important role as vaccination does not cover all high risk HPVs. There is a need to seriously consider a properly organised screening programme, taking into consideration what we already know about the attitude and knowledge of Malaysian women, economic factors and psychosocial issues of the screening method. There is also a large gap in clinical studies on the outcome, management and survival of cervical cancer patients in Malaysia. PMID:25417949

    Purnami, S. W.; Inayati, K. D.; Sari, N. W. Wulan; Chosuvivatwong, V.; Sriplung, H.

    2016-04-01

    Cervical cancer is one of the mostly widely cancer cause of the women death in the world including Indonesia. Most cervical cancer patients come to the hospital already in an advanced stadium. As a result, the treatment of cervical cancer becomes more difficult and even can increase the death's risk. One of parameter that can be used to assess successfully of treatment is the probability of survival. This study raises the issue of cervical cancer survival patients at Dr. Soetomo Hospital using stratified Cox regression based on six factors such as age, stadium, treatment initiation, companion disease, complication, and anemia. Stratified Cox model is used because there is one independent variable that does not satisfy the proportional hazards assumption that is stadium. The results of the stratified Cox model show that the complication variable is significant factor which influent survival probability of cervical cancer patient. The obtained hazard ratio is 7.35. It means that cervical cancer patient who has complication is at risk of dying 7.35 times greater than patient who did not has complication. While the adjusted survival curves showed that stadium IV had the lowest probability of survival.

    1992-01-01

    High rates of cervical cancer were reported in New Mexico in the early 1970s, with especially high rates for minority women. We examined data collected from 1970 to 1987 for invasive cervical cancer and cervical carcinoma in situ for New Mexico's Hispanic, American Indian, and non-Hispanic white women to determine whether changes had occurred in cervical cancer rates since earlier reports. To further characterize the epidemiology of cervical cancer in New Mexico, we reviewed state vital stati...

  3. Intestinal obstructions following the cervical cancer treatment

    Sixty-six intestinal obstructions occured among 2149 patients of cervical cancer treated during period 1961 - 1975. They are divided into four groups, that is, 1.29 cases living with no signs of recurrence after the treatment for obstructions, 2.7 cases that died of obstructions or of complications from its treatment, 3.6 cases that once cured from the obstructions but died from the cancer more than one year after the treatment, 4.24 cases that died from the cancer within one year after the treatment for obstructions. With significantly high incidence, intestinal obstructions are observed with the post-operatory irradiation over 5,000 rads to the whole pelvis or post operatory irradiation using combined telecobalt and small sources. The common sites of obstructions are small intestine to the operated group and sigmoid colon or rectum to the radiotherapy group. Twenty-nine of the patients were treated conservatively and of them 15 are living, intestinal resections and end to end anastomoses were performed to 8 patients, 5 of them are living, but 7 of them suffered from wound disruptions, so the indication for this operation should be carefully decided.

  4. Virus and Cervical Cancer: Role and implication: A Review

    Kalyani Raju

    2015-03-01

    Full Text Available Cervical cancer is one of the leading cancers in women worldwide especially in developing countries. Various etiological factors are described, of which Human papiloma virus (HPV is proved by various molecular epidemiological studies to play a major role. However many co-factors are required and thought to facilitate the action of HPV in cervical carcinogenesis. Here the role of various viruses in cervical cancer and its implication in screening and diagnosis of cervical cancer is highlighted. In-depth knowledge of role of different viruses helps in better screening methods and probably in target therapy / development of an appropriate vaccine. [Biomed Res Ther 2015; 2(3.000: 220-30

    Full Text Available Conventional radiotherapy for cervical cancer relies on clinical examination, 3-dimensional conformal radiotherapy (3D-CRT, and 2-dimensional intracavitary brachytherapy.Excellent local control and survival have been obtained for small early stage cervical cancer with definitive radiotherapy. For bulky and locally advanced disease, the addition of chemotherapy has improved the prognosis but toxicity remains significant. New imaging technology such as positron emission tomography (PET and magnetic resonance imaging (MRI has improved tumor delineation for radiotherapy planning. Image-guided radiotherapy (IGRT may decrease treatment toxicity of whole pelvic radiation because of its potential for bone marrow, bowel, and bladder sparring. Tumor shrinkage during whole pelvic IGRT may optimize image-guided brachytherapy (IGBT, allowing for better local control and reduced toxicity for patients with cervical cancer. IGRT and IGBT should be integrated in future prospective studies for cervical cancer.

    2009-02-01

    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.

  3. Nuclear expression of Rac1 in cervical premalignant lesions and cervical cancer cells

    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

  4. Socioecological perspectives on cervical cancer and cervical cancer screening among Asian American women.

    Lee, Jongwon; Carvallo, Mauricio

    2014-10-01

    Although cervical cancer is one of the most commonly diagnosed cancers among Vietnamese American women (VAW) and Korean American women (KAW), both groups consistently report much lower rates of cervical cancer screening compared with other Asian ethnic subgroups and non-Hispanic Whites. This study aimed to explore multilevel factors that may underlie low screening rates among VAW and KAW living in a city where their ethnic communities are relatively small. The socioecological model was used as a conceptual framework. Thirty participants were conveniently recruited from ethnic beauty salons run by VA and KA cosmetologists in Albuquerque, New Mexico. The participants' average age was 44.6 years (SD = .50; range = 21-60). Most participants were married (80 %) and employed (73.3 %), and had health insurance (83.3 %). A qualitative interview was conducted in Vietnamese or Korean and transcribed verbatim. A thematic content analysis was used to identify major codes, categories, and patterns across the transcripts. The study identified several factors at the individual (e.g., pregnancy, poverty, personality), interpersonal (e.g., family responsibility, mother as influential referent), and community (e.g., lack of availability, community size) levels. The study sheds light on four major areas that must be taken into consideration in the development of culturally appropriate, community-based interventions aimed to reduce disparities in cervical cancer screening among ethnic minority women in the United States: (1) ethnic community size and geographic location; (2) cross-cultural similarities and dissimilarities; (3) targeting of not only unmarried young women, but also close referents; and (4) utilization of trusted resources within social networks.

The initial step involved use of confirmatory factor analysis, that included the following variables: access to and satisfaction with health care, and enabling and predisposing cultural and health beliefs. Structural equation model analyses were conducted on factors related to cervical cancer screening.Results: Age, marital status, employment, household income, and having health insurance, but not educational level, were significantly related to cervical screening status. Predisposing and enabling factors were positively associated with cervical cancer screening. The cultural factor was significantly related to the enabling factor or the satisfaction with health care factor.Conclusion: This model highlights the significance of sociocultural factors in relation to cervical cancer screening. These factors were significant, with cultural, predisposing, enabling, and health belief factors and access to and satisfaction with health care reinforcing the need to assist Chinese American women with poor English fluency in translation and awareness of the importance of cervical

  6. Surface activity, lipid profiles and their implications in cervical cancer.

    2005-01-01

    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

    Full Text Available Cervical cancer incidence and mortality rates in Serbia are among the highest in Europe and data on Human papilloma virus (HPV type distribution are scarce. The aim of this study was to determine the prevalence of HPV types in archival specimens of cervical cancer tissues of women in the Serbian population. A total of 45 paraffin-embedded tissue samples of cervical carcinoma were used in this study. The procedure included deparaffinization of tissue samples, DNA extraction, PCR, gel electrophoresis and HPV genotyping by direct sequencing. HPV was detected in 32 samples (71%. Genotyping revealed the presence of 6 high-risk HPV types 16, 18, 33, 45, 53 and 58, where HPV type 16 was the most prevalent type (73.7%. The results of this study and further studies will provide more detailed information about HPV genotype distribution and may contribute to the formulation of national guidelines for the prevention of cervical cancer.

  8. Small cell cervical cancer: an unusual finding at cholecystectomy.

    Boyle, Emily

    2012-02-01

    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.

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

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

    2001-01-01

    Full Text Available Cytological screening using the Pap-smear led to a remarkable reduction of the mortality of cervical cancer. However, due to subjective test criteria it is hampered by poor inter- and intra-observer agreement. More reproducible assays are expected to improve the current screening and avoid unnecessary medical intervention and psychological distress for the affected women. Cervical cancer arises as consequence of persistent high risk papillomavirus (HR-HPV infections. Expression of two viral oncogenes, E6 and E7, in epithelial stem cells is required to initiate and maintain cervical carcinogenesis and results in significant overexpression of the cellular p16INK4a protein. Since this protein is not expressed in normal cervical squamous epithelia, screening for p16INK4a over-expressing cells allows to specifically identify dysplastic lesions, and significantly reduces the inter-observer disagreement of the conventional cytological or histological tests. Progression of preneoplastic lesions to invasive cancers is associated with extensive recombination of viral and cellular genomes which can be monitored by detection of papillomavirus oncogene transcripts (APOT assay derived from integrated viral genome copies. Detection of integrated type oncogene transcripts points to far advanced dysplasia or invasive cancers and thus represents a progression marker for cervical lesions. These new assays discussed here will help to improve current limitations in cervical cancer screening, diagnosis, and therapy control.

  11. Second primary cancers in survivors of cervical cancer in the Netherlands: Implications for prevention and surveillance

    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

    2012-01-01

    Cervical cancer is third in incidence and fourth in mortality among cancers of women worldwide. Epidemiological studies have shown that human papillomavirus (HPV) is necessary, if not sufficient, to cause nearly 100% of cervical cancers. HPV testing is useful in primary screening for cervical neoplasms. The value of HPV detection or genotyping is potentially useful in triage of borderline or low-grade abnormal cervical cytology, follow-up after treatment of cervical intraepithelial neoplasia,...

  13. Multihelix rotating shield brachytherapy for cervical cancer

    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 (D90 of HR-CTV) were the two metrics used as the basis for evaluation and

    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.

    Full Text Available 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.

    Background: Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV) have been successful interventions for prevention of invasive cervical cancer (ICC). Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical screening in these countries. Therefore, ICC is usually diagnosed in advanced stages with poor prognosis in these countries. We performed a priority setting exercise and suggested priorities for prevention of ICC in this setting. Methods: We invited experts and researchers to a workshop and asked them to list important suggestions for ICC prevention in Iran. After merging similar items and removing the duplicates, we asked the experts to rank the list of suggested items. We used a strategy grid and Go-zone analysis to determine final list of priorities for ICC prevention in Iran. Results: From 26 final items suggested as priorities for prevention of ICC, the most important priorities were developing national guidelines for cervical screening and quality control protocol for patient follow-up and management of precancerous lesions. In addition, we emphasized considering insurance coverage for cervical screening, public awareness, and research priorities, and establishment of a cervical screening registry. Conclusion: A comprehensive approach and implementation of organized cervical screening program is necessary for prevention of ICC in Iran and other low incidence Muslim countries. Because of high cost for vaccination and low incidence of cervical cancer, we do not recommend HPV vaccination for the time being in Iran.

    Full Text Available Background: Cervical cancer is the second most common cancer among Iranian women and among the few cancers that could be easily diagnosed in the pre-malignant stage. We aimed to assess the status of cervical cancer screening in women referred to health care centres in Tabriz, northwest Iran. Materials and Methods: This descriptive-analytical study was done on 441 women referred to health care centres of Tabriz, northwest Iran. The centres were selected using the multi-stage cluster sampling method. The participants were selected from the active records of those centres. A questionnaire regarding the socio-demographic characteristics and cervical cancer screening and reasons for referring or not referring for screening was completed by the participants A P < 0.05 was considered as significant. Results: Out of the participants 49.4% of women had done the Pap smear test while 50.6% had never done this test. The main reason why women had not performed cervical cancer screening was being unaware of the importance of it (46.1%. Logistic regression analysis with adjustment showed a significant relationship between screening and awareness scores (OR = 1.17, CI = 95%:1.12-1.23, when the effect of other confounding factors [total awareness scores, risk factors (marriage or having sexual intercourse at a young age, history of obvious cervical infection, cautery, cryotherapy or repeated curettage, age and type of family planning] in screening was controlled. Conclusion: Suitable and continuous educational programmes especially for high risk women should be implemented through the health care services. Preparing educational brochures and pamphlets and providing adequate training on the necessity of early referral and marriage counseling could also be effective in improving woman′s awareness and performance.

  1. Determining Adequate Margins in Head and Neck Cancers: Practice and Continued Challenges.

    Williams, Michelle D

    2016-09-01

    Margin assessment remains a critical component of oncologic care for head and neck cancer patients. As an integrated team, both surgeons and pathologists work together to assess margins in these complex patients. Differences in method of margin sampling can impact obtainable information and effect outcomes. Additionally, what distance is an "adequate or clear" margin for patient care continues to be debated. Ultimately, future studies and potentially secondary modalities to augment pathologic assessment of margin assessment (i.e., in situ imaging or molecular assessment) may enhance local control in head and neck cancer patients.

    Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

  3. Cervical cancer screening in Belgium and overscreening of adolescents.

    Van Kerrebroeck, Helena; Makar, Amin

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

  4. Advances in diagnosis and treatment of metastatic cervical cancer.

    Li, Haoran; Wu, Xiaohua; Cheng, Xi

    2016-07-01

    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

    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.

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

  17. Quantitative DNA methylation analysis of candidate genes in cervical cancer.

    Erin M Siegel

    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.

  19. Holistic care of the patient with cervical cancer.

    McMullin, M

    1992-12-01

    Participation by women in screening programs for cervical cancer is far from optimal, and many lives are lost because of this. Cervical cancer is common, and is easily detected and treated. It has a good prognosis for cure if detected early in its course. Effective screening has been shown to have a major role in decreasing the morbidity and mortality associated with cervical cancer. Therefore, there is a need for increased public health education and availability of screening programs for women. It is particularly important that public health efforts reach women in the lower socioeconomic groups who are less apt to exhibit health promotive behaviors. Women of Latin American heritage are at particularly high risk because of cultural barriers to the discussion of sexual practices. Until public health interventions are more successful, cervical cancer will continue to pose a major threat to women who are either too embarrassed or too misinformed to understand that prevention is an integral part of women's health care. Nurses view patients in a holistic way. It is this philosophy of care that offers women who are diagnosed with cervical cancer a means to adapt successfully to the psychologic and physiologic stresses associated with the diagnosis. Nurses need to recognize this strength and to offer holistic approaches to women in crisis. No two patients deal with a diagnosis of cancer in the same manner. A major challenge to nurses across a hospital community continuum is to provide comprehensive psychologic and physiologic assessment of a women's response to a diagnosis of cervical cancer and to provide effective and holistic intervention when necessary.

    2015-01-01

    Background:Occult invasive cervical cancer discovered after simple hysterectomy is not common, radical parame‑trectomy (RP) is a preferred option for young women. However, the morbidity of RP was high. The aim of our study is to assess the incidence of parametrial involvement in patients who underwent radical parametrectomy for occult cervical cancer or radical hysterectomy for early‑stage cervical cancer and to suggest an algorithm for the triage of patients with occult cervical cancer to avoid RP. Methods:A total of 13 patients with occult cervical cancer who had undergone RP with an upper vaginectomy and pelvic lymphadenectomy were included in this retrospective study. Data on the clinicopathologic characteristics of the cases were collected. The published literature was also reviewed, and low risk factors for parametrial involvement in early‑stage cervical cancer were analyzed. Results:Of the 13 patients, 9 had a stage IB1 lesion, and 4 had a stage IA2 lesion. There were four patients with grade 1 disease, seven with grade 2 disease, and two with grade 3 disease. The median age of the entire patients was 41years. The most common indication for extrafascial hysterectomy was cervical intraepithelial neoplasia 3. Three patients had visible lesions measuring 10–30mm, in diameter and ten patients had cervical stromal invasions with depths ranging from 4 to 9mm; only one patient had more than 50% stromal invasion, and four patients had lymph‑vascular space invasion (LVSI). Perioperative complications included intraoperative bowel injury, blood transfusion, vesico‑vaginal ifstula, and ileus (1 case for each). Postoperative pathologic examination results did not show residual disease or parametrial involvement. One patient with positive lymph nodes received concurrent radiation therapy. Only one patient experienced recurrence. Conclusions:Perioperative complications following RP were common, whereas the incidence of parametrial involve‑ment was very low

    Walentowicz-Sadłecka, Małgorzata; Sadłecki, Paweł; Marszałek, Andrzej; Grabiec, Marek

    2012-01-01

    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. PMID:23421059

    Objective: To assess the value of sentinel lymph node (SLN) localization by lymphoscintigraphy and gamma probe detection in early cervical cancer. Methods: A total of 27 patients with operable invasive early cervical cancer and clinically proved negative pelvic lymph nodes were included in this study. The 99Tcm-dextran of 74 MBq (2 mCi) was injected around the cervix at 2( and 10(. Lymphoscintigraphy and gamma probe detection were used to find the SLN. Results: The SLN was identified in 27 patients. The sensitivity and specificity of the SLN detection to predict the metastasis of the pelvic lymph node were 100% and 100% respectively. Conclusion: Identification of the SLN using radionuclide is feasible and possible in women with early cervical cancer.

  8. Preprocessing for Automating Early Detection of Cervical Cancer

    Das, Abhishek; Bhattacharyya, Debasis

    2011-01-01

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

  11. The epidemiology of hypopharynx and cervical esophagus cancer.

    Popescu, C R; Bertesteanu, S V G; Mirea, D; Grigore, Raluca; lonescu, Diana; Popescu, B

    2010-01-01

    At the beginning of the 21st century the hypopharynx and the cervical esophagus cancer represents a major issue for all countries of the world. The epidemiology of the hypopharynx and cervical esophagus cancer deals with the spread of the disease in the human population with regard to sex, age, profession, time and space, as well as risk factors that contribute to these phenomena. The main goal is to investigate the causes and the factors involved in the development of the tumors at the pharyngoesophageal junction, knowledge that contributes to the latest therapeutic assessment through interdisciplinary collaboration (E.N.T. surgeon, general surgeon, radiation oncologist, chemotherapist, and nutritionist). The epidemiology of the hypopharynx and cervical esophagus cancer includes three major areas of interest: descriptive (the study of the spread in mass population), analytical (the study of causal risk factors on the disease) and experimental (that verifies by experiments on animals the prior identified hypothesis).

  12. The Epidemiology of Human Papillomavirus Infection and Cervical Cancer

    F. Xavier Bosch

    2007-01-01

    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.

  13. Roles of plant extracts and constituents in cervical cancer therapy.

    Kma, Lakhan

    2013-01-01

    Cervical cancer is a major health problem worldwide and is the most frequent cause of cancer in women in India. Early detection and affordable drugs with clinical efficacy have to go hand-in-hand in order to comprehensibly address this serious health challenge. Plant-based drugs with potent anticancer effects should add to the efforts to find a cheap drug with limited clinical side effects. Keeping this very purpose in mind, an attempt has been made in this review to explore the potential of plant extracts or constituents known to exhibit antitumorigenic activity or exert cytotoxic effect in human cervical carcinoma cells. Alkaloids such as those isolated from C. vincetoxicum and T. Tanakae, naucleaorals A and B, isolated from the roots of N. orientalis, (6aR)-normecambroline, isolated from the bark of N. dealbata appear promising in different human cervical carcinoma cells with the IC50 of 4.0-8 μg/mL. However, other compounds such as rhinacanthone and neolignans isolated from different plants are not far behind and kill cervical cancer cells at a very low concentrations. Among plant extracts or its constituents that enhance the effect of known anticancer drugs, noni, derived from the plant M. citrifolia perhaps is the best candidate. The cytotoxic potency and apoptotic index of cisplatin was found to significantly enhanced in combination with noni in different human cervical carcinoma cells and it therefore holds significance as promising herbal-based anticancer agent. However, efficacy needs to be further investigated in various cervical cell lines and more importantly, in in vivo cervical cancer models for possible use as an alternative and safe anticancer drug.

  14. Twist and YB-1 gene expression in cervical cancer and cervical intraepithelial neoplasia tissue as well as its correlation with epithelial-mesenchymal transition

    Qin Liu; Hong Li; Yu Zhang

    2016-01-01

    Objective:To study the Twist and YB-1 gene expression in cervical cancer and cervical intraepithelial neoplasia tissue as well as its correlation with epithelial-mesenchymal transition. Methods:Normal cervical tissue, cervical intraepithelial neoplasia tissue and cervical cancer tissue were collected for study. ELISA kits were used to detect Twist, YB-1, E-cadherin,β-catenin, N-cadherin and Vimentin contents in cervical tissue, and immunohistochemistry was used to detect Twist and YB-1 expression levels in cervical tissue.Results:Twist and YB-1 contents, cell positive rate and immunohistochemical scores as well as N-cadherin and Vimentin contents in cervical cancer tissue and cervical intraepithelial neoplasia tissue were significantly higher than those in normal cervical tissue while E-cadherin andβ-catenin contents were lower than those in normal cervical tissue; Twist and YB-1 contents, cell positive rate and immunohistochemical scores as well as N-cadherin and Vimentin contents in cervical cancer tissue were significantly higher than those in cervical intraepithelial neoplasia tissue while E-cadherin andβ-catenin contents were lower than those in cervical intraepithelial neoplasia tissue; the higher the Twist and YB-1 expression levels in cervical cancer tissue, the lower the E-cadherin andβ-catenin contents, and the higher the N-cadherin and Vimentin contents.Conclusions: Twist and YB-1 gene overexpression can promote epithelial-mesenchymal transition to be involved in the occurrence of cervical cancer and cervical intraepithelial neoplasia.

    Feng Sun; Xiao-qin Ha; Tong-de Lv; Chuan-ping Xing; Bin Liu; Xiao-zhe Cao

    2009-01-01

    Objective: Cervical cancer (CC) is the second most common type of cancer in women worldwide, after breast cancer. High-risk human papillomaviruses (HR-HPVs) are considered to be the major causes of cervical cancer. HPV16 is the most common type of HR-HPVs and HPV16 E6 gene is one of the major oncogenes. Specific mutations are considered as dangerous factors causing CC. This study was designed to find mutations of HPV16 E6 and the relationship between the mutations and the happening of CC.Methods: The tissue DNA was extracted from 15 biopsies of CC. Part of HPV16 E6 gene (nucleotide 201-523) was amplified by polymerase chain reaction (PCR) from the CC tissue DNA. The PCR fragments were sequenced and analyzed.Results: The result of PCR showed that the positive rate of HPV16 E6 was 93.33% (14/15). After sequencing and analyzing, in the 13 out of 14 PCR fragments, 4 maintained prototype (30.77%), 8 had a same 350G mutation (61.54%), and 1 had a 249G mutation (7.69%).Conclusion: This study suggest that there is a high infection rate of HPV in cervical cancer and most of the HPV16 E6 gene has mutations. Those mutations may have an association with the development of cervical cancer.

  17. Gompertzian stochastic model with delay effect to cervical cancer growth

    In this paper, a Gompertzian stochastic model with time delay is introduced to describe the cervical cancer growth. The parameters values of the mathematical model are estimated via Levenberg-Marquardt optimization method of non-linear least squares. We apply Milstein scheme for solving the stochastic model numerically. The efficiency of mathematical model is measured by comparing the simulated result and the clinical data of cervical cancer growth. Low values of Mean-Square Error (MSE) of Gompertzian stochastic model with delay effect indicate good fits

  19. Surgical Treatment of Early-Stage Cervical Cancer.

    Brucker, Sara Y; Ulrich, Uwe A

    2016-01-01

    Surgical treatment of cervical cancer has been a cornerstone in the management of this malignancy for more than 100 years. Today, for early-stage and low-risk cervical cancer, surgery is still considered the gold standard. If the preoperative assessment of the tumor reveals a situation prompting postoperative adjuvant radiochemotherapy, the latter should be planned as the primary treatment option, being preceded by staging laparoscopy including pelvic and paraaortic lymph node dissection. As an alternative to the open approach, the definitive surgical treatment should be either performed laparoscopically, or be laparoscopic-assisted, or laparoscopically robotic-assisted.

    In this paper, a Gompertzian model with random effects is introduced to describe the cervical cancer growth. The parameters values of the mathematical model are estimated via maximum likehood estimation. We apply 4-stage Runge-Kutta (SRK4) for solving the stochastic model numerically. The efficiency of mathematical model is measured by comparing the simulated result and the clinical data of the cervical cancer growth. Low values of root mean-square error (RMSE) of Gompertzian model with random effect indicate good fits.

  5. Women’s perceived susceptibility to and utilisation of cervical cancer screening services in Malawi

    Melanie Y. Hami

    2014-10-01

    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

  6. Two cytological methods for screening for cervical cancer

    Kirschner, B.; Simonsen, K.; Junge, J.

    2008-01-01

    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...

    Ran Yan; Feng Li

    2016-01-01

    Objective:To detect the expression of both FR-α protein and ki-67 in cervical cancer tissues, and discuss the relationship between them and clinical significance.Methods:Using immunohistochemical method test normal cervical tissue and cervical cancer tissue before FR-α protein expression and the expression of Ki-67.Results:FR- protein expression in normal cervical tissues was positive for 7.0% while in cervical cancer tissue the positive rate was 82.1%. The difference was statistically significant. Ki-67 protein expression in normal cervical tissues was 0% while in cervical cancer tissue the positive rate was 80.2%. The difference was statistically significant. The two protein expression in cervical cancer stageⅠ,Ⅱ and stageⅢ were different, but the difference was not statistically significant. In cervical cancer tissues, both the two protein were positively correlated. There are correlations between them. Difference was statistically significant.Conclusion:FR-α elevated protein expression is involved in the pathogenesis of cervical cancer. FR-α protein expression in cervical cancer and precancerous tissue has correlation with Ki-67, FR-α protein maybe participate in the occurrence and development of the cell proliferation in cervical cancer.

  8. Cervical Cancer Knowledge, Perceptions and Screening Behaviour Among Female University Students in Ghana.

    Binka, Charity; Nyarko, Samuel H; Doku, David T

    2016-06-01

    Cervical cancer is becoming a leading cause of death among women in developing countries. Nevertheless, little is known regarding knowledge and perception of cervical cancer and screening behaviour particularly among female tertiary students in Ghana. This study sought to examine the knowledge and perceptions of cervical cancer and screening behaviour among female students in the University of Cape Coast and Ghana Institute of Management and Public Administration in Ghana. A cross-sectional survey design was adopted for the study. Systematic and stratified random sampling techniques were used to select 410 participants for the study. The study found that the participants lacked knowledge on specific risk factors and symptoms of cervical cancer. Also, even though the participants had a fair perception of cervical cancer, they had a poor cervical cancer screening behaviour. Awareness of cervical cancer was significantly influenced by religious affiliation while cervical cancer screening was significantly determined by the working status of the participants. Specific knowledge on cervical cancer and its risk factors as well as regular screening behaviour is paramount to the prevention of cervical cancer. Consequently, the University Health Services should focus on promoting regular cervical cancer awareness campaigns and screening among the students particularly, females. PMID:25957285

  10. Caudal epidural anesthesia during intracavitary brachytherapy for cervical cancer

    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)

  11. Should helical tomotherapy replace brachytherapy for cervical cancer? Case report

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

    The optoelectronic method is one of the most promising concepts of biophysical program of the diagnostics of CIN and cervical cancer. Objectives of the work are evaluation of sensitivity and specificity of the optoelectronic method in the detection of CIN and cervical cancer. The paper shows correlation between the pNOR number and sensitivity/specificity of the optoelectronic method. The study included 293 patients with abnormal cervical cytology result and the following examinations: examination with the use of the optoelectronic method — Truscreen, colposcopic examination, and histopathologic biopsy. Specificity of the optoelectronic method for LGSIL was estimated at 65.70%, for HGSIL and squamous cell carcinoma of cervix amounted to 90.38%. Specificity of the optoelectronic method used to confirm lack of cervical pathology was estimated at 78.89%. The field under the ROC curve for the optoelectronic method was estimated at 0.88 (95% CI, 0.84-0.92) which shows high diagnostic value of the test in the detection of HGSIL and squamous cell carcinoma. The optoelectronic method is characterised by high usefulness in the detection of CIN, present in the squamous epithelium and squamous cell carcinoma of cervix.

  20. HPV genotyping and site of viral integration in cervical cancers in Indian women.

    Poulami Das

    Full Text Available Persistent HPV infection plays a major role in cervical cancer. This study was undertaken to identify HPV types in a cohort of Indian women with locally advanced cervical cancer as well as to determine the physical state and/or site of viral integration in the host genome. Pretreatment biopsies (n = 270 from patients were screened for HPV infection by a high throughput HPV genotyping assay based on luminex xMAP technology as well as MY09/11 PCR and SPF1/2 PCR. Overall HPV positivity was observed to be 95%, with HPV16 being most common (63% followed by infection with HPV18. Integration status of the virus was identified using Amplification of Papillomavirus Oncogene Transcripts (APOT assay in a subset of samples positive for HPV16 and/or HPV18 (n = 86 and with an adequate follow-up. The data was correlated with clinical outcome of the patients. Integration of the viral genome was observed in 79% of the cases and a preference for integration into the chromosomal loci 1p, 3q, 6q, 11q, 13q and 20q was seen. Clinical data revealed that the physical state of the virus (integrated or episomal could be an important prognostic marker for cervical cancer.

  1. Inhibitors of apoptosis proteins in human cervical cancer

    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

We conducted a retrospective analysis in patients treated for advanced cervical cancer in order to investigate patient characteristics and prognosis of older patients.Methods: Medical records were collected of 159 patients with cervical cancer who had been treated with radiotherapy or combined radiotherapy and chemotherapy from January 2007 to January 2009. The patients were divided into two age groups: (1 patients ≥65 years old, and (2 patients 0.05. Seventy-six patients had human papillomavirus (HPV at diagnosis (twelve women ≥65 years, 64 women ≤65 years; P = 0.000. Forty-two women tested positive for HPV 16, while 32 women tested positive for HPV 18 respectively. Pelvic and/or paraaortic lymph-node metastasis was found in 25 patients (eight in group 1, 17 in group 2; P = 0.960 on computed tomography scan. Of the 159 patients analyzed, sixteen patients (16/52 in group 1 received concurrent chemotherapy, while 96 (96/107 in group 2 completed that treatment.Conclusions: Cervical cancer has the same prognosis in old and young women. Age may not be an independent increased risk of death in women with cervical cancer, and the age-group is at lower risk for virulent HPV strands (HPV 16/18 compared to younger patients. Treatment recommendations were implemented less often for older patients. Radiotherapy remained the most common treatment chosen for elderly patients. This confirms that there is a stronger need to pay attention to the elderly patient.Keywords: cervical cancer, older

  3. Challenges in Prevention and Care Delivery for Women with Cervical Cancer in Sub-Saharan Africa

    Randall, Thomas C.; Ghebre, Rahel

    2016-01-01

    Virtually all cases of invasive cervical cancer are associated with infection by high-risk strains of human papilloma virus. Effective primary and secondary prevention programs, as well as effective treatment for early-stage invasive cancer have dramatically reduced the burden of cervical cancer in high-income countries; 85% of the mortality from cervical cancer now occurs in low- and middle-income countries. This article provides an overview of challenges to cervical cancer care in sub-Saharan Africa (SSA) and identifies areas for programmatic development to meet the global development goal to reduce cancer-related mortality. Advanced stage at presentation and gaps in prevention, screening, diagnostic, and treatment capacities contribute to reduced cervical cancer survival. Cost-effective cervical cancer screening strategies implemented in low resource settings can reduce cervical cancer mortality. Patient- and system-based barriers need to be addressed as part of any cervical cancer control program. Limited human capacity and infrastructure in SSA are major barriers to comprehensive cervical cancer care. Management of early-stage, locally advanced or metastatic cervical cancer involves multispecialty care, including gynecology oncology, medical oncology, radiology, pathology, radiation oncology, and palliative care. Investment in cervical cancer care programs in low- and middle-income countries will need to include effective recruitment programs to engage women in the community to access cancer screening and diagnosis services. Though cervical cancer is a preventable and treatable cancer, the challenges to cervical control in SSA are great and will require a broadly integrated and sustained effort by multiple stakeholders before meaningful progress can be achieved.

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

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

    Full Text Available Background: Cervical cancer is the second leading cause of morbidity and mortality among the females worldwide. India has the highest burden of cervical cancer patients, accounting for approximately one-fifth of the cases in world. Nurses being an important link between the doctors and female patients in OPD or wards, it is imperative that they should be aware of the facts about cervical cancer and especially of screening techniques which can be utilized in low-resource settings. Methods: A cross-sectional interview based study was done among 200 nurses of a tertiary care teaching institute from June 2013 to July 2013, to assess the knowledge and awareness of nursing staff regarding causes of cervical cancer and its prevention and early detection. Results: Among all participated nurses, 85% (n=170 were aware of the term cancer cervix and 45% reported that it is the most frequent gynaecological cancer in India. Only 30.6% reported that it is the leading cause of death among women due to cancer. Young age at first intercourse, multiple sex partners, cigarette smoking, high parity and lower socio-economic status were correctly responded by 13%, 48%, 16%, 9% and 13% of participants respectively, as risk factors for cervical cancer. None of the participants knew about the VIA method of screening for cervical cancer. Among 119 of those participants who knew that cervical cancer can be detected by Pap smear, only 5 (4% had ever undergone Pap smear examination. Conclusions: Nurses identify certain aspects of cervical cancer correctly but their knowledge is not adequate, hence necessary changes should be made in their curriculum.

  9. Treatment results of neck dissection with the preservation of cervical nerves for hypopharyngeal cancer

    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.

  10. Tc17 cells in patients with uterine cervical cancer.

    Yan Zhang

    Full Text Available BACKGROUND: The existence of Tc17 cells was recently shown in several types of infectious and autoimmune diseases, but their distribution and functions in uterine cervical cancer (UCC have not been fully elucidated. METHODS: The frequency of Tc17 cells in peripheral blood samples obtained from UCC patients, cervical intraepithelial neoplasia (CIN patients and healthy controls was determined by flow cytometry. Besides, the prevalence of Tc17 cells and their relationships to Th17 cells and Foxp3-expressing T cells as well as microvessels in tissue samples of the patients were assessed by immunohistochemistry staining. RESULTS: Compared to controls, patients with UCC or CIN had a higher proportion of Tc17 cells in both peripheral blood and cervical tissues, but the level of Tc17 cells in UCC tissues was significantly higher than that in CIN tissues. Besides, the increased level of Tc17 in UCC patients was associated with the status of pelvic lymph node metastases and increased microvessel density. Finally, significant correlations of infiltration between Tc17 cells and Th17 cells or Foxp3-expressing T cells were observed in UCC and CIN tissues. CONCLUSIONS: This study indicates that Tc17 cell infiltration in cervical cancers is associated with cancer progression accompanied by increased infiltrations of Th17 cells and regulatory T cells as well as promoted tumor vasculogenesis.

  12. Quality control in screening programs for cervical cancer

    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. This document contains some useful indexes calculated to ensure quality throughout the process. There should be the measurement of quality throughout the screening process that allows collecting of reliable data as well as correcting deficiencies

    Lopamudra Das

    2015-01-01

    Full Text Available Cervical cancer is the second most common female cancer worldwide and a disease of concern due to its high rate of incidence of about 500,000 women annually and is responsible for about 280,000 deaths in a year. The mortality and morbidity of cervical cancer are reduced through mass screening via Pap smear, but this technique suffers from very high false negativity of around 30% to 40% and hence the sensitivity of this technique is not more than 60%. Electrical bioimpedance study employing cytosensors over a frequency range offers instantaneous and quantitative means to monitor cellular events and is an upcoming technique in real time to classify cells as normal and abnormal ones. This technology is exploited for label-free detection of diseases by identifying and measuring nonbiological parameters of the cell which may carry the disease signature.

    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

    2012-10-01

    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

We retrospectively analysed the clinical data of 241 patients undergoing oesophagogastric cervical anastomosis using disposable circular staplings after oesophagectomy in the People's Hospital of Henan Province, from August 2009 to July 2012. A total of 240 patients were anastomosed successfully. One patient had a partially torn oesophagus and underwent repair because the wrong stapler size was used. No operative death occurred. Seven patients (2.9 %) had postoperative cervical anastomotic leakage but recovered after short-term conservative treatment, and three patients had obvious gastro-oesophageal reflux after eating. No intrathoracic anastomotic leakage or other anastomotic instrument-related complications occurred. During a median follow-up period of 13.8 months, no anastomotic stricture was found in each patient. The application of oesophagogastric cervical anastomosis using circular anastomat after oesophagectomy for cancer was safe and feasible. PMID:27011487

    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.

    Narayanswamy, Ramkumar; Sharpe, John P.; Johnson, Kristina M.

    1994-05-01

    Automation of the Pap-smear cervical screening method is highly desirable as it relieves tedium for the human operators, reduces cost and should increase accuracy and provide repeatability. We present here the design for a high-throughput optoelectronic system which forms the first stage of a two stage system to automate pap-smear screening. We use a mathematical morphological technique called the hit-or-miss transform to identify the suspicious areas on a pap-smear slide. This algorithm is implemented using a VanderLugt architecture and a time-sequential ANDing smart pixel array.

    2015-01-01

    BACKGROUND: The incidence rates of cervical cancer and the coverage in cervical cancer screening are usually reported by including in the denominator all women from the general population. However, after hysterectomy women are not at risk anymore of developing cervical cancer. Therefore, it makes...... sense to determine the indicators also for the true at-risk populations. We described the frequency of total hysterectomy in Denmark and its impact on the calculated incidence of cervical cancer and the screening coverage. MATERIAL AND METHODS: With data from five Danish population-based registries......, the incidence rate of cervical cancer and the screening coverage for women aged 23-64 years on 31 December 2010 were calculated with and without adjustments for hysterectomies undertaken for reasons other than cervical cancer. They were calculated as the number of cases divided by 1) the total number of woman...

    Full Text Available Background & Objective: Cervical cancer is the second prevalent women cancer in the world. This cancer is found preventable because of having the prolong time before the appearance, its complications and the available proper screening program and possibility of the primary lesion treatment. Since the Health Belief Model is one of the applicable praxeology model in health education to prevent and control of diseases. Therefore, this study was aimed to determine the Health Belief Model components in adopting preventive behaviors in cervical cancer in women. Materials & Methods: This descriptive-analytical study was carried out on 213 married 20-65 year-old women selected by a two-stage sampling method. The data was collected by a valid and reliable questionnaire and interview. This questionnaire based on health belief model correlation (components Perceived Susceptibility and Severity, Perceived Barriers and Benefits, Self-efficacy with behavior survey. The data were analyzed by using descriptive statistics and Mann-Whhitney test, Kruskal-wallis test, and Regression by SPSS software. Results: The mean age of the study group was 40.6 ± 12.1. The results show that 32.5% of them had at least one time examined for Pap smear test out of which only 7.9% of them had this test on a regular interval. Only 12% of them had an adequate knowledge about the cervical cancer and its preventive measure. 90% of them had inappropriate behavior. The average score of knowledge was 6.73± 2.97 which considered as moderate. Regression analysis showed the knowledge (P=0.009, job (P=0.005, perceived barriers (P<0.001 and perceived severity (P=0.036 determine as predictors in the final behavior. Conclusion: Perceived barriers and knowledge behind the strongest predictor of behavior. Educational programs are recommended based on the health belief model with emphasis on reducing barriers and increasing awareness to improve behavior.

  4. Image-Based Brachytherapy for the Treatment of Cervical Cancer

    Cervical cancer is a disease that requires considerable multidisciplinary coordination of care and labor in order to maximize tumor control and survival while minimizing treatment-related toxicity. As with external beam radiation therapy, the use of advanced imaging and 3-dimensional treatment planning has generated a paradigm shift in the delivery of brachytherapy for the treatment of cervical cancer. The use of image-based brachytherapy, most commonly with magnetic resonance imaging (MRI), requires additional attention and effort by the treating physician to prescribe dose to the proper volume and account for adjacent organs at risk. This represents a dramatic change from the classic Manchester approach of orthogonal radiographic images and prescribing dose to point A. We reviewed the history and currently evolving data and recommendations for the clinical use of image-based brachytherapy with an emphasis on MRI-based brachytherapy

    2016-06-01

    When a cervical cancer diagnosis is made during a terminal stage, a woman is faced with many challenges. Although a terminal illness has many negative effects, such as physical pain, scarring, fear, and sexual dysfunction, women may experience a positive impact on their life, such as improved well-being and a greater appreciation of daily life. The individual experience can lead to personal revelations. Sometimes, the diagnosis can even be seen as a blessing. Understanding a personal experience in a real-life context of the terminal stages of disease is important. This story shares the day-to-day journey of a woman living with a terminal illness of cervical cancer. PMID:27206304

  12. Overcoming Barriers to Cervical Cancer Screening Among Asian American Women

    Fang, Carolyn Y.; Ma, Grace X.; Tan, Yin

    2011-01-01

    Significant disparities in cervical cancer incidence and mortality exist among ethnic minority women, and in particular, among Asian American women. These disparities have been attributed primarily to differences in screening rates across ethnic/racial groups. Asian American women have one of the lowest rates of screening compared to other ethnic/racial groups. Yet Asian Americans, who comprise one of the fastest growing populations in the United States, have received the least attention in c...

  13. Tailored radiotherapeutic strategies for disseminated uterine cervical cancer patients

    To investigate the role of radiotherapy (RT) in and to suggest radiotherapeutic strategies for patients presenting with disseminated cervical cancer. We retrospectively analyzed 50 patients diagnosed as the disseminated cervical cancer with distant lymph nodal or visceral organ metastasis between September 1980 and August 2012. Patients were divided into two subgroups according to visceral organ metastasis: 35 patients diagnosed with distant lymph node metastasis only (group A) and 15 patients with visceral organ metastasis (group B). All patients received external beam RT to the pelvis (median dose 45 Gy) and high-dose rate intracavitary RT (median dose 30 Gy). Thirty-nine patients (78%) received chemotherapy. Median follow-up time was 74 months. The 5-year pelvic control rate (PCR) was 85.8%, and the progression-free survival (PFS), and overall survival (OS) rates were 28.7%, and 36.2%, respectively. The major treatment failure was systemic progression (32 patients, 64%). The 5-year PCRs in groups A and B were 87.4% and 74.7%, respectively (p > 0.05). Meanwhile, PFS and OS rates for group A were significantly better than those for group B (35.3% vs. 13.3%, p = 0.010; and 46.3% vs. 13.3%, p = 0.009, respectively). Our data revealed considerable prognostic heterogeneity in disseminated cervical cancer. Even though a high PCR was achieved in patients treated with definitive RT, survival outcomes were dependent on progression of visceral organ metastasis. Therefore, personalized RT and chemotherapy treatment strategies according to the presence of visceral organ metastasis in disseminated cervical cancer patients may help improve clinical outcomes

    2015-01-01

    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.

  19. Preoperative transarterial chemoembolization for cervical cancer: analysis of efficacy

    Objective: To evaluate preoperative transarterial chemoembolization in treating locally advanced cervical cancer and to observe the pathological changes. Methods: Forty-three patients with pathologically proved cervical cancer were enrolled in this study. All patients were treated with transarterial chemoembolization before radical hysterectomy. Bleomycin and cisplantin were infused via bilateral uterine arteries, followed by arterial embolization with gelfoam particles as embolic agent. Radical hysterectomy was performed 20-87 days (mean 38.3 days) after chemoembolization, and the specimen was taken for pathologic examination. Results: (1) complete response (CR) was seen in 4 cases and partial response (PR) in 29 cases, with a total effective rate of 76.7%. (2) The interval between chemoembolization and hysterectomy was a risk factor related to the effect of chemoembolization, i.e. the longer the interval was, the poorer the effect of chemoembolization would be. (3) Pathologically, the tumoral parauterine infiltration was not so severe as estimated before surgery. Conclusion: Preoperative chemoembolization is a safe and effective adjunctive means for the treatment of cervical cancer, which is very helpful for the subsequent radical hysterectomy. (authors)

  20. Therapeutic vaccines against human papillomavirus and cervical cancer.

    Cid-Arregui, Angel

    2009-01-01

    Cervical cancer and its precursor intra-epithelial lesions are linked to infection by a subset of so-called "highrisk" human papillomavirus types, which are estimated to infect nearly four hundred million women worldwide. Two prophylactic vaccines have been commercialized recently targeting HPV16 and 18, the most prevalent viral types found in cervical cancer, which operate through induction of capsid-specific neutralizing antibodies. However, in patients with persistent infection these vaccines have not been found to protect against progression to neoplasia. Attempts are being made to develop therapeutic vaccines targeting nonstructural early viral proteins. Among these, E6 and E7 are the preferred targets, since they are essential for induction and maintenance of the malignant phenotype and are constitutively expressed by the transformed epithelial cells. Here are reviewed the most relevant potential vaccines based on HPV early antigens that have shown efficacy in preclinical models and that are being tested in clinical studies, which should determine their therapeutic capacity for eradicating HPV-induced premalignant and malignant lesions and cure cervical cancer.

    Radiotherapy has been standard therapy for locally advanced squamous cell cervical cancer. Neoadjuvant chemotherapy is being studied to improve responses and survival. We report a phase II study in locally advanced squamous cell cervical cancer (FIGO stages III and IV A) using chemotherapy with bleomycin, methotrexate and cisplatin (BMP) followed by radical radiotherapy. Of the 35 patients, 31 in stage III and 4 in stage IV A, 3 complete responses (CR) and 22 partial responses (PR) were achieved after chemotherapy treatment. Thirty-one patients completed radiotherapy; 19 achieved CR and 4 PR. Five-year actuarial survival for the entire group was 45% (95% confidence interval, 37-53%) with a median survival of 56 months. Patients with CR had a significantly better survival: The 5-year actuarial survival was 74% (95% CI, 59-89%). Recurrence developed at 4 to 19 patients. The most frequent side-effects were nausea and vomiting. Myelosuppression and impaired renal function also occurred. There was no evidence of radiotherapy toxicity enhancement. The stage and Karnofsky index were significant prognostic factors. It is concluded that MBP chemotherapy in advanced cervical cancer is effective and, followed by radiotherapy, allows a good control of this tumor. The group of patients with complete response have a low rate of recurrences and a long survival chance. (orig.).

    Yang Qiuan; Qian Shao; Yang Xingsheng

    2009-01-01

    Objective:To evaluate the current approaches for multimodality therapy for stage ⅠB cervical cancer. Methods:The relevant literature has served as a source for identified high or intermediate risks and management of stage ⅠB cervical cancer. Result:The high risks include pelvic lymph node metastasis (PLNM), positive resection margin (PRM), and the in-volvement of parametrium (IPM). The intermediate risks include deep stromal invasion (DSI), bulky tumor size ( BTS), lymphovascular space invasion (LVSI). Adeno-carcinomatous histo-type is the new risk feature relevant to poor prognoses. Both radical hysterectomy plus bilateral pelvic lymph node dissection(PLND) and radical radiotherapy have proven to be equally effec-tive. Surgery is more performed for stage ⅠB1 disease;radiotherapy or chemoradiotherapy is preferable for stage ⅠB2 disease. For patients with one high risk or two of intermediate risks, radical hysterectomy plus PLND followed by concurrent chemoradiotherapy can improve overall survival(OS) and disease-free survival (DFS). Conclusion:The management should be indi-vidualized for stage ⅠB cervical cancer. The optimized multidisciplinary therapy can benefit pa-tients with the best cure and minimum morbidity and complications.

    Full Text Available Objective: To investigate the expression of peroxisome proliferation-activated receptor γ (PPARγ, p27 and Ki67 in cervical cancer and its clinical significance. Methods: The expression of PPARγ, p27 and Ki67 in the tissues of 42 patients with cervical cancer, 28 with cervical intraepithelial neoplasia (CIN and 12 with normal cervix was detected using immunohistochemistry. Results:The positive rate of PPARγ protein in cervical cancer tissue (76.2% was significantly higher than in CIN (53.6% and normal cervical tissue (8.3% (P<0.05 orP<0.01, which was also evidently higher in CIN than in normal cervical tissue (P<0.05. The positive rate of p27 protein in cervical cancer tissue (31.0% was significantly lower than in CIN (57.1% and normal cervical tissue (83.3% (P<0.05 or P<0.01, and that in CIN had a markedly lower tendency compared with normal cervical tissue (P<0.05. The positive rate of Ki67 protein in cervical cancer tissue (100.0% was apparently higher than in CIN (85.7% and normal cervical tissue (33.3% (P<0.05 or P<0.01, which was also markedly higher in CIN than in normal cervical tissue (P<0.01. The expression of PPARγ, p27 and Ki67 proteins was not associated with the clinicopathological features of patients, including the age, histological types, pathological grading and clinical staging (P>0.05.Conclusion: Abnormal expression of PPARγ, p27 and Ki67 may play important roles in occurrence and progression of cervical cancer, and hence, joint detection of PPARγ, p27 and Ki67 can be used to diagnose early CIN and cervical cancer.

  5. The roles and clinical significance of microRNAs in cervical cancer.

    Wang, Fenfen; Li, Baohua; Xie, Xing

    2016-02-01

    Cervical carcinogenesis induced by persistent human papillomavirus (HPV) infection represents a stepwise progression from precursors to invasive cervical cancer. Accumulated evidence has shown aberrant expression of microRNAs (miRNAs) in cervical cancer tissues and cells. Further studies reveal that miRNAs play key roles in the initiation and progression of cervical cancer, via specific signaling pathways, including E6-p53, E7-pRb, phosphoinositide-3 kinase (PI3K)-Akt, Notch, Wnt/β-catenin, and Hedgehog pathways. Some studies demonstrate that miRNAs might serve as biomarkers or therapeutic targets, presenting a potential prospect in clinical practice. All results provide new insights into the function of miRNAs and the pathogenesis of cervical cancer induced by viral oncoproteins. New approaches for miRNA-based prevention and management for cervical cancer will be developed in the future. PMID:26356641

    Abstract: In 2012, the International Agency for Research on Cancer concluded that there was consistent and sufficient epidemiological, experimental and mechanistic evidence of carcinogenicity to humans for 12 HPV types (HPV16, HPV18, HPV31, HPV33, HPV35, HPV39, HPV45, HPV51, HPV52, HPV56, HPV58 and HPV59) for cervical cancer. Therefore, these types were considered as 1A carcinogens. They all belong to the family of the -Papillomaviridae, in particular to the species 5 (HPV51), 6 (HPV56), 7 (H...

  9. Radiation-sparing managements for cervical cancer: a developing countries perspective

    de la Garza Jaime

    2006-11-01

    Full Text Available Abstract Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1 that these are not inferior to the "standard" in terms of either survival or quality of life; 2 that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3 that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

  10. Human papillomavirus research on the prevention, diagnosis, and prognosis of cervical cancer in Taiwan.

    Chao, Angel; Huang, Huei-Jean; Lai, Chyong-Huey

    2012-01-01

    Cervical cancer is third in incidence and fourth in mortality among cancers of women worldwide. Epidemiological studies have shown that human papillomavirus (HPV) is necessary, if not sufficient, to cause nearly 100% of cervical cancers. HPV testing is useful in primary screening for cervical neoplasms. The value of HPV detection or genotyping is potentially useful in triage of borderline or low-grade abnormal cervical cytology, follow-up after treatment of cervical intraepithelial neoplasia, assessment of prognosis and treatment planning for invasive cervical cancer. Studies from Chang Gung Memorial Hospital have defined the genotype distribution of cervical cancer in Taiwan and confirmed the independent prognostic value of the HPV genotype in cervical cancer. The cost-effectiveness of using HPV testing in prevention and management of cervical neoplasms depends on the medical and public health infrastructure of the individual country. The population-based HPV prevalence and genotype distribution as well as longitudinal follow-up studies have established strong support for incorporating HPV testing with cervical cytology and for future comparisons of HPV epidemiology before and after implementation of HPV prophylactic vaccines in Taiwan. Future directions in HPV research are discussed. PMID:22913856

    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.

  12. MicroRNA-373 functions as an oncogene and targets YOD1 gene in cervical cancer

    miR-373 was reported to be elevated in several tumors; however, the role of miR-373 in cervical cancer has not been investigated. In this study we aimed to investigate the role of miR-373 in tumorigenicity of cervical cancer cells in vivo and in vitro. The expression of miR-373 was investigated using real-time reverse transcription-polymerase chain reaction assay in 45 cervical specimens and cervical cancer cell lines. The role of miR-373 in tumorigenicity of cervical cancer cells was assessed by cell proliferation, colony formation in vitro as well as tumor growth assays in vivo with the overexpression of miR-373 or gene silencing. The functional target gene of miR-373 in cervical cancer cells was identified using integrated bioinformatics analysis, gene expression arrays, and luciferase assay. We founded that the expression of miR-373 is upregulated in human cervical cancer tissues and cervical carcinoma cell lines when compared to the corresponding noncancerous tissues. Ectopic overexpression of miR-373 in human cervical cancer cells promoted cell growth in vitro and tumorigenicity in vivo, whereas silencing the expression of miR-373 decreased the rate of cell growth. YOD1 was identified as a direct and functional target of miR-373 in cervical cancer cells. Expression levels of miR-373 were inversely correlated with YOD1 levels in human cervical cancer tissues. RNAi-mediated knockdown of YOD1 phenocopied the proliferation-promoting effect of miR-373. Moreover, overexpression of YOD1 abrogated miR-373-induced proliferation of cervical cancer cells. These results demonstrate that miR-373 increases proliferation by directly targeting YOD1, a new potential therapeutic target in cervical cancer. - Highlights: • The expression of miR-373 is upregulated in human cervical cancer tissues. • miR-373 effects as oncogenic miRNA in cervical cancer in vitro and in vivo. • miR-373 increases proliferation of cervical cancer cells by directly targeting YOD1

    One of the most preventable cancers in women is cervical cancer. Pap smear test is an effective screening program; however, it is not conducted very frequently. The aim of this study is explaining the determinants affecting women’s participation in the Pap smear test based on precaution adoption process model with a qualitative approach. This study was a qualitative approach using a Directed Content Analysis methodology which was conducted in 2014. Participants were 30 rural women who participated in this study voluntarily in sarvabad, Iran. Purposive sampling was initiated and continued until data saturation. Semi-structured interviews were the primary method of data collection. Data were analyzed using qualitative content analysis and continuous comparisons. Women`s information and awareness about cervical cancer and Pap smear is insufficient and most of them believed that they were not at risk; however, they perceived the severity of the disease. Some of them had no adequate understanding of the test benefits. They pointed to the lack of time, financial difficulties, fear of test result and lack of awareness as the main barriers against the Pap smear test; however, they did not say that they were not willing to do the test. Findings could help health policy makers to find the right area and purpose to facilitate the participation of women in the Pap smear test. PMID:26755465

  17. Comprehensive knowledge about cervical cancer is low among women in Northwest Ethiopia

    Getahun Frehiwot

    2013-01-01

    Full Text Available Abstract Background Cervical cancer is the first most common cancer in women in sub-Saharan Africa followed by breast cancer. In Ethiopia, the incidence of cervical cancer is high i.e. 35.9 per 100,000 women. Low level of awareness, lack of effective screening programs, overshadowed by other health priorities (such as acquired immune deficiency syndrome, tuberculosis and malaria and insufficient attention to women’s health are the possible factors for the observed higher incidence rate of cervical cancers in the country. Data on knowledge of Ethiopian women regarding cervical cancer is lacking. The aim of this study was to assess the knowledge of women about cervical cancer and associated factors. Methods A community based cross-sectional survey was conducted from April 4-16, 2010 in Gondar town, Northwest Ethiopia. A total of 633 women aged 15 years and above were interviewed using semi-structured questionnaire by 8 trained data collectors and 2 supervisors. SPSS Windows version 15.0 was employed for data entry and analysis. Result Of all the respondents, 495 (78.7% of them had heard about cervical cancer and only 195 (31% of them were knowledgeable about the disease. Conclusion The knowledge of women on cervical cancer was found to be poor. Education about the disease must include information on risk factors, sign and symptoms of cervical cancer.

    Most invasive cervical cancers in industrialized countries are due to the lack of Pap test coverage, very few are due to screening failures. This study aimed at quantifying the proportion of invasive cancers occurring in nonscreened or underscreened women and that in women with a previous negative screening, that is, screening failure, during the first two screening rounds (1996-2002) and in the following rounds (2003-2008) in the Emilia-Romagna region. All cases of invasive cancers registered in the regional cancer registry between 1996 and 2008 were classified according to screening history through a record linkage with the screening programme registry. The incidence significantly decreased from 11.6/100 000 to 8.7/100 000; this decrease is due to a reduction in squamous cell cancers (annual percentage change -6.2; confidence interval: -7.8, -4.6) and advanced cancers (annual percentage change -6.6; confidence interval: -8.8, -4.3), whereas adenocarcinomas and microinvasive cancers were essentially stable. The proportion of cancers among women not yet invited and among nonresponders decreased over the two periods, from 45.5 to 33.3%. In contrast, the proportion of women with a previous negative Pap test less than 5 years and 5 years or more before cancer incidence increased from 5.7 to 13.3% and from 0.3 to 5.5%, respectively. Although nonattendance of the screening programme remains the main barrier to cervical cancer control, the introduction of a more sensitive test, such as the human papillomavirus DNA test, could significantly reduce the burden of disease.

  20. Epigenetics of cervical cancer. An overview and therapeutic perspectives

    Cetina Lucely

    2005-10-01

    Full Text Available Abstract Cervical cancer remains one of the greatest killers of women worldwide. It is difficult to foresee a dramatic increase in cure rate even with the most optimal combination of cytotoxic drugs, surgery, and radiation; therefore, testing of molecular targeted therapies against this malignancy is highly desirable. A number of epigenetic alterations occur during all stages of cervical carcinogenesis in both human papillomavirus and host cellular genomes, which include global DNA hypomethylation, hypermetylation of key tumor suppressor genes, and histone modifications. The reversible nature of epigenetic changes constitutes a target for transcriptional therapies, namely DNA methylation and histone deacetylase inhibitors. To date, studies in patients with cervical cancer have demonstrated the feasibility of reactivating the expression of hypermethylated and silenced tumor suppressor genes as well as the hyperacetylating and inhibitory effect upon histone deacetylase activity in tumor tissues after treatment with demethylating and histone deacetylase inhibitors. In addition, detection of epigenetic changes in cytological smears, serum DNA, and peripheral blood are of potential interest for development of novel biomolecular markers for early detection, prediction of response, and prognosis.

    Objective The aim of this study was to investigate the ability of intravoxel incoherent motion (IVIM) dif usion-weighted magnetic resonance imaging (MRI) to diagnose cervical cancer and to evaluate the response of uterine cervical cancer to radiochemotherapy (CRT). Methods This prospective study was approved by the institutional review board, and informed consent was obtained from al patients. A total of 23 patients with primary cervical cancer who were undergoing CRT and 16 age-matched healthy subjects were prospectively recruited for IVIM (b = 0–800 s/mm2) and stan-dard pelvic MRI. Bi-exponential analysis was performed to derive f (perfusion fraction), D* (pseudo-dif usion coef icient), and D (true molecular dif usion coef icient) in cervical cancer (n = 23) and the normal cervix (n= 16). The apparent dif usion coef icient (standard ADC) was calculated. The independent-samples t-test and paired-samples t-test were used for comparisons. Results Pre-treatment cervical cancer had the lowest standard ADC (1.15 ± 0.13 × 10-3 mm2/s) and D (0.89 ± 0.10 × 10-3 mm2/s) values, and these were significantly dif erent from the normal cervix and post-treatment cervical cancer (P = 0.00). The f (16.67 ± 5.85%) was lowest in pre-treatment cervical cancer and was significantly dif erent from the normal cervix and post-treatment cervical cancer (p = 0.012 and 0.00, respectively). No dif erence was observed in D*. Conclusion IVIM is potential y promising for dif erentiating between the normal cervix and cervical can-cer because pre-treated cervical cancer has low perfusion and dif usion IVIM characteristics. Further, the standard ADC, D, and f of cervical cancer showed a tendency to normalize after CRT; thus, IVIM may be useful for monitoring the response to CRT in cervical cancer.

  4. The expression andprognostic value ofprotein tyrosine kinase 6 inearly-stage cervical squamous cell cancer

    XiaoJingWang; YingXiong; ZeBiaoMa; JianChuanXia; YanFangLi

    2016-01-01

    Background:Protein tyrosine kinase 6 (PTK6) is overexpressed in many epithelial tumors and predicts poor progno‑sis. However, PTK6 expression status and its role in cervical squamous cell cancer are unknown. This study aimed to investigate the expression level and clinical signiifcance of PTK6 in early‑stage cervical squamous cell cancer. Methods:Quantitative reverse transcription‑polymerase chain reaction (qRT‑PCR) and western blotting analysis were performed to detect PTK6 mRNA and protein expression levels in 10 freshly frozen, early‑stage cervical squamous cell cancer specimens and adjacent non‑tumorous cervical tissues. The expression of PTK6 was detected using immuno‑histochemical staining in 150 formalin‑ifxed, paraffn‑embedded, early‑stage cervical squamous cell cancer sections and 10 normal cervical tissue sections. Results:The mRNA and protein levels of PTK6 in cancer tissues were higher than those in adjacent non‑tumorous cervical tissues. Immunohistochemical analysis showed that PTK6 was not expressed in normal cervical tissues but was overexpressed in the cytoplasm of cervical squamous cell cancer cells. The level of PTK6 expression was signiif‑cantly associated with tumor grade (P=0.020). The 5‑year overall survival rate of patients with high PTK6 expression was lower than that of patients with low PTK6 expression (81.3% vs. 96.2%,P=0.008). Multivariate Cox regression analysis showed that the expression level of PTK6 in cervical squamous cell cancer was an independent prognostic factor for patient survival (hazard ratio=5.999, 95% conifdence interval 1.622–22.191,P Conclusions:PTK6 is overexpressed in cervical squamous cell cancer. Increased PTK6 expression is associated with reduced 5‑year overall survival. PTK6 expression is an independent prognostic predictor for cervical cancer.

  6. Accessibility of breast and cervical cancer services in Malaysia.

    1997-12-01

    Despite the fact that Malaysia has good treatment centers for reproductive cancer, mortality rates from breast and cervical cancer are high because of a lack of early detection. Breast cancer mortality rates have risen since 1985, while cervical cancer mortality rates declined from 1985 to 1993 and then increased in 1997. There is no standardized cancer registry, so incidence and mortality rates are likely to be higher than reported. In 1995, the government launched its first nationwide cancer prevention campaign and stressed breast self-examination and yearly examination by a medical professional for woman aged 20 years and above. The same year, eligibility for pap smears was extended to all women who have been or are sexually active and are aged 20-65 years. Between 1993 and 1996, 35% of the breast cancer cases presented at stage 3 or 4, and 93% of these women had a lump of a mean size of 5.3 cm. Cultural taboos prevent women from examining their own bodies, and women fear their husbands will leave them if they have a mastectomy. Malay women also deny themselves preventive care, and sometimes physicians and nurses deny Pap smears to unmarried women. Women are not empowered with the knowledge they need to seek preventive screenings, and older women are difficult to reach with information because they are unlikely to visit maternal-child health or family planning clinics. Malaysia needs to institute a standardized cancer registry and to conduct research that will address the barriers faced by women. PMID:12294552

    The chemokine CXCL12 is highly expressed in gynecologic tumors and is widely known to play a biologically relevant role in tumor growth and spread.Recent evidence suggests that CXCL16,a novel chemokine,is overexpressed in inflammation-associated tumors and mediates pro-tumorigenic effects of inflammation in prostate cancer.We therefore analyzed the expression of CXCL12 and CXCL16 and their respective receptors CXCR4 and CXCR6 in cervical intraepithelial neoplasia (CIN) and cervical cancer and further assessed their association with clinicopathologic features and outcomes.Tissue chip technology and immunohistochemistry were used to analyze the expression of CXCL12,CXCR4,CXCL16,and CXCR6 in healthy cervical tissue (21 cases),CIN (65 cases),and cervical carcinoma (60 cases).The association of protein expression with clinicopathologic features and overall survival was analyzed.These four proteins were clearly detected in membrane and cytoplasm of neoplastic epithelial cells,and their distribution and intensity of expression increased as neoplastic lesions progressed through CIN1,CIN2,and CIN3 to invasive cancer.Furthermore,the expression of CXCR4 was associated significantly with the histologic grade of cervical carcinoma,whereas the expression of CXCR6 was associated significantly with lymph node metastasis.In Kaplan-Meier analysis,patients with high CXCR6 expression had significantly shorter overall survival than did those with low CXCR6 expression.The elevated co-expression levels of CXCL12/CXCR4 and CXCL16/CXCR6 in CIN and cervical carcinoma suggest a durative process in cervical carcinoma development.Moreover,CXCR6 may be useful as a biomarker and a valuable prognostic factor for cervical cancer.

    2011-01-01

    Cervical cancer is the third most common cancer in women in peninsular Malaysia and very prevalent worldwide. HPV vaccination and routine Pap smear testing are the best preventive measures. The objective of this study was to determine the knowledge level of secondary school students from Sarawak, East Malaysia regarding cervical cancer and its prevention. Multistage random sampling with various methods in each step was employed to select the sample of 76 students. Results showed that 61.8% had poor knowledge level of cervical cancer and its prevention. There were 60.5% of students who were aware of cervical cancer with Chinese and form four students showing significantly the highest awareness (pstudents was 22.3% and an association was found between knowledge of cervical cancer with race and HPV vaccination acceptance (pstudents had poor knowledge level of cervical cancer, its prevention and HPV vaccination acceptance. More efforts should be made to improve cervical cancer knowledge and awareness of the public especially secondary school students in Sarawak. This in turn will enhance the practice of prevention against cervical cancer among students. PMID:22126576

    Few studies have assessed the burden of human papillomavirus (HPV) infection in Pakistan. We aim to provide specific information on HPV-type distribution in invasive cervical cancer (ICC) in the country. A total of 280 formalin-fixed paraffin-embedded tissue blocks were consecutively selected from Shaukat Khanum Memorial Cancer Hospital and Research Centre (Lahore, Pakistan). HPV-DNA was detected by SPF10 broad-spectrum PCR followed by DNA enzyme immunoassay and genotyping by LiPA25. HPV-DNA prevalence was 87.5% (95%CI: 83.0-91.1), with 96.1% of cases histologically classified as squamous cell carcinoma. Most of the HPV-DNA positive cases presented single infections (95.9%). HPV16 was the most common type followed by HPV18 and 45. Among HPV-DNA positive, a significantly higher contribution of HPV16/18 was detected in Pakistan (78.4%; 72.7-83.3), compared to Asia (71.6%; 69.9-73.4) and worldwide (70.8%; 69.9-71.8) and a lower contribution of HPVs31/33/45/52/58 (11.1%; 7.9-15.7 vs. 19.8%; 18.3-21.3 and 18.5%; 17.7-19.3). HPV18 or HPV45 positive ICC cases were significantly younger than cases infected by HPV16 (mean age: 43.3, 44.4, 50.5 years, respectively). A routine cervical cancer screening and HPV vaccination program does not yet exist in Pakistan; however, the country could benefit from national integrated efforts for cervical cancer prevention and control. Calculated estimations based on our results show that current HPV vaccine could potentially prevent new ICC cases. PMID:27483322

  12. Ubiquitin B in cervical cancer: critical for the maintenance of cancer stem-like cell characters.

    Yuan Tian

    Full Text Available Cervical cancer cells exhibit an increased requirement for ubiquitin-dependent protein degradation associated with an elevated metabolic turnover rate. Ubiquitin, which is a small, highly conserved protein expressed in all eukaryotic cells, can be covalently linked to certain target proteins to mark them for degradation by the ubiquitin-proteasome system. Previous studies highlight the essential role of Ubiquitin B (UbB and UbB-dependent proteasomal protein degradation in histone deacetylase inhibitor (HDACi -induced tumor selectivity. We hypothesized that UbB plays a critical role in the function of cervical cancer stem cells. We measured endogenous UbB levels in mammospheres in vitro by real-time PCR and Western blotting. The function of UbB in cancer stem-like cells was assessed after knockdown of UbB expression in prolonged Trichostatin A-selected HeLa cells (HeLa/TSA by measuring in vitro cell proliferation, cell apoptosis, invasion, and chemotherapy resistance as well as by measuring in vivo growth in an orthotopic model of cervical cancer. We also assessed the cancer stem cell frequency, tumorsphere formation, and in vivo growth of human cervical cancer xenografts after UbB silencing. We found that HeLa/TSA were resistant to chemotherapy, highly expressed the UbB gene and the stem cell markers Sox2, Oct4 and Nanog. These cells also displayed induced differentiation abilities, including enhanced migration/invasion/malignancy capabilities in vitro and in vivo. Furthermore, an elevated expression of UbB was shown in the tumor samples of chemotherapy patients. Silencing of UbB inhibited tumorsphere formation, lowered the expression of stem cell markers and decreased cervical xenograft growth. Our results demonstrate that UbB was significantly increased in prolonged Trichostatin A-selected HeLa cells and it played a key role in the maintenance of cervical cancer stem-like cells.

    Full Text Available Ahmed Ibrahim1, Vibeke Rasch2, Eero Pukkala3, Arja R Aro1 1Unit for Health Promotion Research, University of Southern Denmark, Esbjerg, Denmark; 2Department of Obstetrics and Gynaecology, Odense University Hospital, Odense, Denmark; 3Finnish Cancer Registry, Institute for Statistical and Epidemiological Cancer Research, Helsinki, Finland Background: Cervical cancer is the second most common cancer among women in Sudan, with more than two-thirds of all women with invasive cervical cancer being diagnosed at an advanced stage (stages III and IV. The lack of a screening program for cervical cancer in Sudan may contribute to the late presentation of this cancer, but other factors potentially associated with advanced stages of cervical cancer at diagnosis are unknown. The purpose of this research was to investigate the relationship between age, marital status, ethnicity, health insurance coverage, residence in an urban vs a rural setting, and stage (at diagnosis of cervical cancer in Sudan. Methods: This was a cross sectional study of 197 women diagnosed with different stages of cervical cancer. Data was obtained from the cancer registry unit at the Radiation and Isotopes Centre in Khartoum for all women diagnosed with cervical cancer in 2007. Results: There was an association between older age and advanced stage (at diagnosis of cervical cancer (odds ratio [OR]: 1.03, 95% confidence interval [CI]: 1.01–1.05. Being of African ethnicity was associated with 76% increased odds (OR: 1.76, 95% CI: 1.01–3.05, living in a rural area was associated with 13% increased odds (OR: 1.13, 95% CI: 1.78–5.50, and being uninsured was associated with an almost eight-fold increase in odds (OR: 7.7, 95% CI: 3.76–15.38. Marital status and education level were not associated with an advanced stage of cervical cancer at diagnosis. Conclusion: Women with cervical cancer who are elderly, not covered by health insurance, of African ethnicity, and living in a rural area

  14. Radio-guided surgery in cervical cancer - first experiences

    Aim: Lymphatic mapping is known to be useful in melanoma and breast cancer. The aim of our study is to evaluate the feasibility of the Sentinel Lymph Node (SLN) biopsy in patients with cervical cancer. Material and Methods: We performed dynamic lymphoscintigraphy in 17 patients with evidence of early stage cervical cancer one day before surgery. We injected subepithelially 99mTc-labelled human colloides, Albu-Res, (on average 88 MBq, 0,2 ml NaCl each) in the cervix at 3, 6, 9 and 12 o'clock. The colloid was filtered before to obtain the small particle fraction between 200-450nm. The dynamic scintigraphy was performed immediately after injection (anterior view, 28 images, 1 minute per frame); static images were required 30 minutes and 2 hours p.i. (anterior and lateral views, 5 minutes per images). Additional the SLN were marked on the skin. After SLN identification by using a hand-held gamma probe a standard lymphadenectomy was done. The harvested lymph nodes were also measured after excision and referred to pathologist (for HE-staining and immunohistochemistry). Results: In 15/17 cases SLN were visualized (7/15 with lymph channels) on scintigraphy and in 13/17 cases the SLN (on average 2) detection by gamma probe was successful. Among these 13 patients we didn't found any false-negatives but in the 2 cases with no visualization of SLN (which should always result in a complete lymphadenectomy) we found lymph node metastasis. Conclusion: Lymphatic mapping in patients with cervical cancer by using scintigraphy and gamma probe seems to be feasible to reduce the morbidity due to radical lymphadenectomy. 15/17 patients underwent a radical lymphadenectomy without benefit for survival. However in 2/17 cases this method failed. Larger studies are needed, we have to evaluate the accuracy of the selective SLN-biopsy in cervical cancer. So we have to discuss questions: is the lymph drainage of injection site equal to lymph drainage of tumor site

  16. Cervical Cancer Screening after Perimenopause: How Is Human Papillomavirus Test Performed?

    2016-01-01

    Cervical cancer is the third most prevalent cancer in women around the world. Recently in Korea, the incidence of cervical cancer has decreased, but in all stages of cervical intraepithelial neoplasia (CIN), CIN has shown a 91% increase from 1999 to 2008. Persistent human papillomavirus (HPV) infection has been found to be the main cause of cervical cancer. HPV types 16 and 18 have been found in 70% of cervical cancer patients around the world. Cervical cancer screening such as cytology has limitations in terms of sensitivity and specificity. A discussion about the need for the HPV test is becoming active in order to compensate for the limitation of cytology. After the role of HPV in cervical cancer was identified, the importance of HPV detection test as a screening was emphasized. Several tests have been developed and each test has its own advantages and disadvantages, and new test method to overcome the disadvantages is still being developed. Today's guidelines and tests are those you would choose from among the large number of cervical cancer screening guidelines and tests, based on the consideration that the selected guidelines and the test are effective.

  4. Expression of Pin1 and Ki67 in Cervical Cancer and Their Significance

    2006-01-01

    In order to investigate the expression levels of Pin1 mRNA and protein in cervical cancer and its association with Ki67 and their clinical significance, amplification of Pin1 gene was examined by RT-PCR, and the expression of both Pin1 and Ki67 protein was detected by immunohistochemistry in cervical cancer tissues. It was shown that the expression levels of Pin1 were higher in cervical cancer than in normal cervical tissues (P<0.05). The expression of Pin1 protein was increased progressively along with the disease process from normal cervix to CIN and to cervical cancer (P<0. 05). No significant difference in the Pin1 expression was found between disease stages (FIGO),pathological grades or pelvic lymph node metastasis status (P>0.05). The expression of Pin1 was significantly higher in adenocarcinoma than insquamous carcinoma of the uterine cervix (P<0.05).In cervical cancer, the overexpression of Pin1 was positively correlated with that of Ki67 (P<0.05). These results suggested that the overexpression of Pin1 was closely related with cancer cell proliferation or progression of cervical cancer and contributed to oncogenesis. Pin1 may serve as a potential marker for cervical cancer diagnosis.

The subjects studied were women with a mean age of 48.18 years, who attended the hospital for cervical biopsy due to the suspected diagnosis of cervical dysplasia or an invasive disease, based on previous suspicious Pap smear. HPV DNA hybridization by HC2 was performed on the cervical biopsies of these patients, to detect HPV infection.Results: During the period of this study, 45 patients had cervical biopsies taken for HPV testing. Seven patients had a negative HC2 result and were found to have no cervical dysplasia on the final pathology review. Seventeen cases with cervical dysplasia and 21 patients with invasive disease were presented; the mean age was 48 years. HC2 testing for HPV were found to be positive in patients with cervical dysplasia, invasive carcinoma, and all in 5 (29.4%, 13 (61.9% and 18 (47.4%, respectively. The sensitivity of the test is 47% and specificity is 100%.Conclusion: The use of molecular detection of HPV DNA by HC2 in biopsy is feasible and effective. These results confirm the finding that HPV contributes to the etiology of cervical cancer in Muslim society.Keywords: HPV, subtyping, cervical neoplasia

  9. Cyclin A1 promoter hypermethylation in human papillomavirus-associated cervical cancer

    The aim of this study was to evaluate epigenetic status of cyclin A1 in human papillomavirus-associated cervical cancer. Y. Tokumaru et al., Cancer Res 64, 5982-7 (Sep 1, 2004)demonstrated in head and neck squamous-cell cancer an inverse correlation between cyclin A1 promoter hypermethylation and TP53 mutation. Human papillomavirus-associated cervical cancer, however, is deprived of TP53 function by a different mechanism. Therefore, it was of interest to investigate the epigenetic alterations during multistep cervical cancer development. In this study, we performed duplex methylation-specific PCR and reverse transcriptase PCR on several cervical cancer cell lines and microdissected cervical cancers. Furthermore, the incidence of cyclin A1 methylation was studied in 43 samples of white blood cells, 25 normal cervices, and 24, 5 and 30 human papillomavirus-associated premalignant, microinvasive and invasive cervical lesions, respectively. We demonstrated cyclin A1 methylation to be commonly found in cervical cancer, both in vitro and in vivo, with its physiological role being to decrease gene expression. More important, this study demonstrated that not only is cyclin A1 promoter hypermethylation strikingly common in cervical cancer, but is also specific to the invasive phenotype in comparison with other histopathological stages during multistep carcinogenesis. None of the normal cells and low-grade squamous intraepithelial lesions exhibited methylation. In contrast, 36.6%, 60% and 93.3% of high-grade squamous intraepithelial lesions, microinvasive and invasive cancers, respectively, showed methylation. This methylation study indicated that cyclin A1 is a potential tumor marker for early diagnosis of invasive cervical cancer

    2014-01-01

    Cervical cancer is one of the leading causes of cancer in women worldwide. One way by which the incidence of this malignant disease can be minimized is by imparting knowledge through health education. This study aimed at developing an educational package on cervical cancer (EPCC) and determining its effectiveness in terms of significant increase in knowledge of rural women regarding cervical cancer. A one group pre-test, post-test design was adopted. Thirty rural women were selected using a convenient sampling method. Data were collected using a demographic questionnaire and a structured knowledge questionnaire developed by the researchers. The EPCC was designed for a duration of one hour and 10 minutes. The structured knowledge questionnaire was first administered as the pre-test, following which knowledge on cervical cancer was imparted using the EPCC. On the 8th day, the post-test was administered. Data were analyzed using descriptive and inferential statistics. The mean post-test knowledge score of the women regarding cervical cancer was significantly higher than that of their mean pre-test score, indicating that the EPCC was effective in improving the knowledge of rural women on cervical cancer. The association between pre-test knowledge scores and selected demo-graphic variables were computed using chi-square test showed that pre-test knowledge score of the women regarding cervical cancer was independent of all the socio-demographic variables. It was concluded that the EPCC is effective in improving the knowledge of women, regarding cervical cancer. Since the prevalence of cervical cancer is high, there is an immediate need to educate women on prevention of cervical cancer. PMID:25169495

  11. Robotic thyroidectomy and cervical neck dissection for thyroid cancer

    Paek, Se Hyun

    2016-01-01

    A robotic approach for thyroid surgery was developed to overcome the limitations of endoscopic thyroidectomy and provide many technical advantages. This approach facilitates the surgeon’s control through a magnified three-dimensional view, decreased tremor, and freedom of motion with articulated instruments. Robotic thyroidectomy is safe and technically feasible in patients with well-differentiated, low-risk thyroid cancer. Furthermore, robotic thyroidectomy may become a good surgical alternative option for patients with more advanced thyroid cancer. Our modified bilateral axillo-breast approach (BABA) for central and lateral cervical neck lymph node (LN) dissection has yielded excellent surgical outcomes as an open procedure. The incorporation of robotics in thyroid cancer surgery will continue to evolve, and the surgical indications for robotic thyroidectomy will continue to expand. Further analyses that include long-term outcomes and randomized comparative trials remain important. PMID:27294043

    Cervical cancer is the second most common cause of cancer mortality among women with the vast majority of patients in developing countries. Bhutanese refugees in the United States are from South Central Asia, the 4th leading region of the world for cervical cancer incidence. Over the past few years, Bhutanese refugees have increased significantly in Nebraska. This study evaluates current knowledge of cervical cancer and screening practices among the Bhutanese refugee women in Omaha, Nebraska. The study aimed to investigate cervical cancer and screening knowledge and perceptions about the susceptibility and severity of cervical cancer and perceived benefits and barriers to screening. Self-administered questionnaires and focus groups based on the Health Belief Model were conducted among 42 healthy women from the Bhutanese refugee community in Omaha. The study revealed a significant lack of knowledge in this community regarding cervical cancer and screening practices, with only 22.2 % reporting ever hearing of a Pap test and 13.9 % reporting ever having one. Only 33.3 % of women were in agreement with their own perceived susceptibility to cervical cancer. Women who reported ever hearing about the Pap test tended to believe more strongly about curability of the disease if discovered early than women who never heard about the test (71.4 vs. 45.0 %, for the two groups. respectively). Refugee populations in the United States are in need for tailored cancer education programs especially when being resettled from countries with high risk for cancer. PMID:25060231

  14. [Radical trachelectomy -- surgery for preserving woman's fertility in patients with invasive cervical cancer].

    Kostov, I; Vasilev, N; Nacheva, A; Lazarov, I

    2013-01-01

    For the past 15 years gynecological oncologists have been seeking ways to preserve woman's fertility when treating invasive cervical cancer. Many cases of cervical cancer are diagnosed in young woman who wish to preserve their fertility. As more women are delaying childbearing, fertility preservation has become an important consideration. The standard surgical treatment for stage IA2-IB1 cervical cancer is a radical hysterectomy and bilateral pelvic lymphadenectomy. This surgery includes removal of the uterus and cervix, radical resection of the parametrial tissue and upper vagina, and complete pelvic lymphadenectomy. Obviously, the standard treatment does not allow future childbearing. For some women with small localized invasive cervical cancers, there is hope for pregnancy after treatment. Radical trachelectomy is a fertility-sparing surgical approach developed in France in 1994 by Dr. Daniel Dargent for the treatment of early invasive cervical cancer. The radical trachelectomy operation has been described and performed abdominally, assisted vaginally by laparoscopy and robotically. PMID:24505637

    Hammer, Anne; Mejlgaard, Else; Gravitt, Patti;

    2015-01-01

    INTRODUCTION: The prevalence of human papillomavirus (HPV)16/18 in cervical cancer may decrease with age. This study aimed to describe the HPV genotype distribution in Danish women aged 55 years or older with cervical cancer. MATERIAL AND METHODS: In this cross-sectional study we identified 153...... cases of cervical cancer diagnosed at Aarhus University Hospital, Denmark (1990-2012) and Copenhagen University Hospital Herlev, Denmark (2007-2012). All women had surgery to treat the disease. HPV genotyping was performed on cervical cancer tissue using the INNO LiPA HPV genotyping extra (Fujirebio......, Belgium) at the Department of Pathology, Aarhus University Hospital, Denmark. The main outcome was to estimate the age-specific prevalence of high-risk HPV genotypes included in the bivalent, the quadrivalent, and the nonavalent vaccine. RESULTS: Of 121 cases of cervical cancer included in this study, 113...

  16. cDNA Microarray Analysis of Serially Sampled Cervical Cancer Specimens From Patients Treated With Thermochemoradiotherapy

    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.

    2013-12-15

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

    Full Text Available Dermatomyositis (DM is a rare syndrome which belongs to the group of idiopathic inflammatory myopathies (IIM. The diagnosis of DM in adults is an indication for diagnostic evaluation towards malignancy. The exacerbation of clinical symptoms or laboratory markers of DM may indicate the relapse of neoplasm, therefore close follow-up visits of patients are obligatory. We present the case of a woman with a two-month history of progressive muscle weakness, dysphagia and oedemo-erythematous skin lesions limited to the face and trunk.

    A descriptive and cross-sectional study of 50 women with some kind of alteration in their Pap smear results in the last triennium, and who belong to the health area of 'Jose Marti Perez' University Polyclinic from Santiago de Cuba, was carried out during the first semester of 2008 in order to determine the gynecobstetric risk factors in the cervical cancer course. Multiparity and the intergenesic period over a year, as well as the beginning of sexual intercourse in adolescence, the use of hormonal contraceptives, and history of sexually transmitted infections were predominant among them.

    Luckett, Rebecca; Feldman, Sarah

    2016-06-01

    Cervical cancer causes significant morbidity and mortality worldwide. Most cervical cancers are associated with oncogenic human papillomavirus (HPV), and vaccination with any of 3 available HPV vaccines is anticipated to greatly reduce the burden of cervical cancer. This review provides an overview of the burden of HPV, the efficacy and clinical effectiveness of the bivalent (HPV 16, 18), quadrivalent (HPV 6, 11, 16, 18) and 9vHPV (HPV 6, 11, 16, 1831, 33, 45, 52, 58) vaccines in order to assess the anticipated impact on cervical cancer. All three vaccines show high efficacy in prevention of vaccine-specific HPV-type infection and associated high-grade cervical dysplasia in HPV-naïve women. Early clinical effectiveness data for the bivalent and quadrivalent vaccine demonstrate reduced rates of HPV 16 and 18 prevalence in vaccinated cohorts; data evaluating cervical dysplasia and cervical procedures as outcomes will shed further light on the clinical effectiveness of both vaccines. The bivalent vaccine has demonstrated cross-protection to non-vaccine HPV types, including the types in the 9vHPV vaccine. No clinical effectiveness data is yet available for the 9vHPV vaccine.  While HPV vaccination has great promise to reduce cervical cancer morbidity and mortality, estimated benefits are largely theoretical at present. Large population-based clinical effectiveness studies will provide long-term immunogenicity and effectiveness, as well as assessment of cervical cancer as an endpoint, particularly as young vaccinated women enter the appropriate age range to initiate screening for cervical cancer. Strengthening screening and treatment programs will likely have the greatest impact in the short-term on cervical cancer morbidity and mortality. PMID:26588179

    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 main purpose of this study was to assess the knowledge of cervical cancer among women in rural Nepal and explore the feasibility and impact of a community-based awareness program on cervical cancer. Community-based educational meetings on cervical cancer and its prevention were conducted among women's groups in rural Nepal. Through a questionnaire, the women's baseline knowledge of risk factors, symptoms, and perceived risk of cervical cancer were identified. The willingness to participate in cervical cancer screening was compared before and after the educational meeting. The meetings were followed by a cervical cancer screening program. Among the 122 participants at the educational meeting, only 6 % had heard of cervical cancer. Their baseline knowledge of risk factors and symptoms was poor. The proportion of women willing to participate in cervical screening increased from 15.6 to 100 % after attending the educational meeting. All the study subjects participated in the screening program. Additionally, the study participants recruited a further 222 of their peers for screening. Poor knowledge of cervical cancer among women in rural Nepal highlights the urgency of public awareness programs for cervical cancer at a national level. A community-based awareness program can change women's attitude to cervical screening, and women's groups can play a major role in promoting participation in cervical cancer screening programs.

    Full Text Available Background: Cervical cancer is a largely preventable disease. In western countries, the incidence of and mortality associated with cervical cancer has reduced substantially following the introduction of effective cervical screening programmes. This is in contrast to what is obtained in Africa including Nigeria where cervical screening is rudimentary or non- existent. Aim: This study seeks to assess the knowledge, level of perception and the attitude of female staff and students of Niger Delta University, Nigeria, towards cervical cancer screening. Methods: A questionnaire was used for data collection. The questions were made to capture the objectives of the study. Results: Most of the respondents 278 (72% were aware of cervical cancer, while only 182 (50.6% were aware of cervical cancer screening. Pap smear was the most popular screening test mentioned by respondents 100 (41.2%, while some respondents (8.5% of staff and 16.3% of students wrongly believed that blood test is used for cervical cancer screening. There is a significant association between awareness and practice of cervical cancer screening amongst staff and students (X2 = 29.4, P=0.00. Conclusion: The study shows that awareness of cervical cancer screening was higher amongst students than staff of Niger Delta University. Uptake was low in both staff and students. There was an association between awareness and practice of cervical cancer screening amongst respondents. Overall, a greater proportion of the staff respondents had little or no knowledge of cervical cancer screening.

  8. Hedgehog pathway regulators influence cervical cancer cell proliferation, survival and migration

    Highlights: ► Unknown cellular mutations complement papillomavirus-induced carcinogenesis. ► Hedgehog pathway components are expressed by cervical cancer cells. ► Hedgehog pathway activators and inhibitors regulate cervical cancer cell biology. ► Cell immortalization by papillomavirus and activation of Hedgehog are independent. -- Abstract: Human papillomavirus (HPV) infection is considered to be a primary hit that causes cervical cancer. However, infection with this agent, although needed, is not sufficient for a cancer to develop. Additional cellular changes are required to complement the action of HPV, but the precise nature of these changes is not clear. Here, we studied the function of the Hedgehog (Hh) signaling pathway in cervical cancer. The Hh pathway can have a role in a number of cancers, including those of liver, lung and digestive tract. We found that components of the Hh pathway are expressed in several cervical cancer cell lines, indicating that there could exists an autocrine Hh signaling loop in these cells. Inhibition of Hh signaling reduces proliferation and survival of the cervical cancer cells and induces their apoptosis as seen by the up-regulation of the pro-apoptotic protein cleaved caspase 3. Our results indicate that Hh signaling is not induced directly by HPV-encoded proteins but rather that Hh-activating mutations are selected in cells initially immortalized by HPV. Sonic Hedgehog (Shh) ligand induces proliferation and promotes migration of the cervical cancer cells studied. Together, these results indicate pro-survival and protective roles of an activated Hh signaling pathway in cervical cancer-derived cells, and suggest that inhibition of this pathway may be a therapeutic option in fighting cervical cancer.

  10. Arsenic trioxide inhibits cell proliferation and human papillomavirus oncogene expression in cervical cancer cells

    Highlights: • As2O3 inhibits growth of cervical cancer cells and expression of HPV oncogenes in these cells. • HPV-negative cervical cancer cells are more sensitive to As2O3 than HPV-positive cervical cancer cells. • HPV-18 positive cervical cancer cells are more sensitive to As2O3 than HPV-16 positive cancer cells. • Down-regulation of HPV oncogenes by As2O3 is partially due to the diminished AP-1 binding. - Abstract: Arsenic trioxide (As2O3) has shown therapeutic effects in some leukemias and solid cancers. However, the molecular mechanisms of its anticancer efficacy have not been clearly elucidated, particularly in solid cancers. Our previous data showed that As2O3 induced apoptosis of human papillomavirus (HPV) 16 DNA-immortalized human cervical epithelial cells and cervical cancer cells and inhibited the expression of HPV oncogenes in these cells. In the present study, we systemically examined the effects of As2O3 on five human cervical cancer cell lines and explored the possible molecular mechanisms. MTT assay showed that HPV-negative C33A cells were more sensitive to growth inhibition induced by As2O3 than HPV-positive cervical cancer cells, and HPV 18-positive HeLa and C4-I cells were more sensitive to As2O3 than HPV 16-positive CaSki and SiHa cells. After As2O3 treatment, both mRNA and protein levels of HPV E6 and E7 obviously decreased in all HPV positive cell lines. In contrast, p53 and Rb protein levels increased in all tested cell lines. Transcription factor AP-1 protein expression decreased significantly in HeLa, CaSki and C33A cells with ELISA method. These results suggest that As2O3 is a potential anticancer drug for cervical cancer

    2015-08-01

    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

  12. Poly(ADP-Ribose) Polymerase in Cervical Cancer Pathogenesis: Mechanism and Potential Role for PARP Inhibitors.

    Kotsopoulos, Ioannis C; Kucukmetin, Ali; Mukhopadhyay, Asima; Lunec, John; Curtin, Nicola J

    2016-05-01

    Treatment options for disease recurrence of women treated for locally advanced and advanced cervical cancer are very limited-largely palliative chemotherapy. The low efficacy of the currently available drugs raises the need for new targeted agents. Poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitors (PARPi) have emerged as a promising class of chemotherapeutic agents in cancers associated with defects in DNA repair. Their therapeutic potential in cervical cancer is currently being evaluated in 3 ongoing clinical trials. Here we review the available information regarding all the aspects of PARP in cervical intraepithelial neoplasia and invasive cervical cancer, from expression and the mechanism of action to the role of the polymorphisms in the pathogenesis of the disease, as well as the potential of the inhibitors. We finally propose a new unifying theory regarding the role of PARPs in the development of cervical carcinomas. PMID:26905326

    Bhat, Samatha; Kabekkodu, Shama Prasada; Noronha, Ashish; Satyamoorthy, Kapaettu

    2016-02-01

    Cervical cancer is the second most common cancer among women worldwide. About 528,000 women are diagnosed with cervical cancer contributing to around 266,000 deaths, across the globe every year. Out of these, the burden of 226,000 (85%) deaths occurs in the developing countries, who are less resource intensive to manage the disease. This is despite the fact that cervical cancer is amenable for early detection due to its long and relatively well-known natural history prior to its culmination as invasive disease. Infection with high risk human papillomavirus (hrHPVs) is essential but not sufficient to cause cervical cancer. Although it was thought that genetic mutations alone was sufficient to cause cervical cancer, the current epidemiological and molecular studies have shown that HPV infection along with genetic and epigenetic changes are frequently associated and essential for initiation, development and progression of the disease. Moreover, aberrant DNA methylation in host and HPV genome can be utilized not only as biomarkers for early detection, disease progression, diagnosis and prognosis of cervical cancer but also to design effective therapeutic strategies. In this review, we focus on recent studies on DNA methylation changes in cervical cancer and their potential role as biomarkers for early diagnosis, prognosis and targeted therapy. PMID:26743075

    2014-08-01

    Mortality rates for cervical cancer (CC) in Chile are higher than those of developed countries and it has an unequal socioeconomic distribution. The recognition of human papilloma virus (HPV) as the causal agent of cervical cancer in the early 80's changed the prevention paradigms. Current goals are to prevent HPV infection by vaccination before the onset of sexual activity and to detect HPV infection in women older than 30 years. This article reviews CC prevention and early detection methods, discusses relevant evidence to support a change in Chile and presents an innovation proposal. A strategy of primary screening based on HPV detection followed by triage of HPV-positive women by colposcopy in primary care or by cytological or molecular reflex testing is proposed. Due to the existence in Chile of a well-organized nationwide CC prevention program, the replacement of a low-sensitivity screening test such as the Papanicolau test with a highly sensitive one such as HPV detection, could quickly improve the effectiveness of the program. The program also has a network of personnel qualified to conduct naked-eye inspections of the cervix, who could easily be trained to perform triage colposcopy. The incorporation of new prevention strategies could reduce the deaths of Chilean women and correct inequities. PMID:25424677

  15. Radiation induced enterocolitis in uterine cervical cancer after radiotherapy

    Objective: To approach the cause of radiation induced enterocolitis and its relationship with retropostion of the uterus in uterine cervical cancer after radiotherapy. Methods: Twenty-two patients with radiation induced enterocolitis, from 212 patients with uterine cervical cancer who had received radio-therapy during 2002-2005, were retrospectively analyzed. The incidence between patients with anteposition and patients with retroposition of uterus was compared. The distance between uterine central axis and the rectum of 15 patients with anteposition and 15 patients with retroposition of the uterus was measured, as well as the uterus retroversional flexion angle of the retropositioned uterus. Results: The incidence of radiation enterocolitis in patients with retroposition of uterus was obviously higher than that in patients with anteposition (χ2=21.10, P<0.01). The distance between point C and the rectum in patients with retroposition of uterus was shorter(t=7.33, P<0.05). The retroversional flexion angle of retropostitioned uterus were between 9-22 degree with a median angle of 17 degree. Conclusion: The incidence of radiation induced enterocolitis is higher in patients with retropostition of uterus after radiotherapy, because the distance between the uterine central axis and the rectum is shorter. The y axis and z axis often form an acute angle in the rectal direction during after-loading therapy, which would had led to an excessive dose to the rectum. (authors)

  16. Extrafascial hysterectomy in IB2 cervical cancer after radio chemotherapy

    Aim: To evaluate overall and disease free survival in cervical cancer IB2 patients with concomitant chemoradiotherapy and posterior extrafascial hysterectomy treatment. Methods: Between July 2005 to December 2009, a total of 31 eligible patients with IB2 cervical cancer were treated with chemoradiotherapy and posterior hysterectomy in the Carlos Van Buren Hospital Oncology Unit. Radiotherapy consisted in external pelvic radiation and a utero-vaginal brachytherapy with low rate doses to get preoperatory doses between 70 and 75 Gy to the A point and a concomitant Cisplatin based chemotherapy. After this treatment, the patients received extrafascial hysterectomy 4 to 6 weeks completed chemoradiotherapy. Results: The mean age was 41 ± 8 years. 81% of the patients had an spinocelular carcinoma. The extrafascial hysterectomy was made between 4 to 6 weeks post-radiation in 85% of the patients. 79% and 13% of the patients received 5 and 4 chemotherapy cycles respectively. The median follow up was 38 months. The 5 years overall survival and disease free survival estimates were 86% and 79% respectively. There was a significant difference between subgroups of patients with and without macroscopic residual disease in the operatory specimen (p<0.001). Conclusion: Our survival is similar to published results with the same treatment. The presence of macroscopic residual disease in the hysterectomy specimen could be a factor of prognostic value

  17. Current status and perspectives of brachytherapy for cervical cancer.

    Toita, Takafumi

    2009-02-01

    Standard definitive radiotherapy for cervical cancer consists of whole pelvic external beam radiotherapy (EBRT) and intracavitary brachytherapy (ICBT). In Japan, high-dose-rate ICBT (HDR-ICBT) has been utilized in clinical practice for more than 40 years. Several randomized clinical trials demonstrated that HDR-ICBT achieved comparative outcomes, both for pelvic control and incidences of late complications, to low-dose-rate (LDR) ICBT. In addition, HDR-ICBT has some potential advantages over LDR-ICBT, leading to further improvement in treatment results. Prior to the current computer planning systems, some excellent treatment planning concepts were established. At present, systems modified from these concepts, or novel approaches, such as image-guided brachytherapy (IGBT) are under investigation. One serious problem to be solved in HDR-ICBT for cervical cancer is that of the discrepancy in standard treatment schedules for combination HDR-ICBT and EBRT between the United States and Japan. Prospective studies are ongoing to assess the efficacy and toxicity of the Japanese schedule. PMID:19225920

  18. Cervical necrosis after chemoradiation for cervical cancer: case series and literature review

    The aim of this study was to assess the management of cervical necrosis (CN) following radiotherapy (RT) and the impact of smoking status. This rare complication mimics a neoplastic recurrence, and causes concern among attending physicians. Between July 2008 and March 2013, 5 women on 285 with localized cervical cancer had a CN following RT. Patients were treated with concomitant chemoradiation. The medical records were reviewed to abstract demographic and clinical information until March 2013. 1.75% (95% confidence interval: 0.23 to 3.28%) developed CN. All patients were smokers with a mean of 19.5 pack-years (range: 7.5-45 pack-years). All patients were treated with weekly Cisplatin chemotherapy and external beam radiation to the pelvis, 45 Gy in 25 fractions. Four patients received an extra boost with a median dose of 7.2 Gy (range: 5.4-10 Gy). All patients had intracavitary brachytherapy (range: 27.9 to 30 Gy). Clinical presentation was similar for all the cases: vaginal discharge associated with pain. Mean time for time post-radiation therapy to necrosis was 9.3 months (range: 2.2-20.5 months). Standard workup was done to exclude cancer recurrence: biopsies and radiologic imaging. Conservative treatment was performed with excellent results. Resolution of the necrosis was complete after a few months (range: 1 to 4 months). Median follow-up until March 2013 was 19 months. All the patients were alive with no clinical evidence of disease. This study, the largest to date, shows that conservative management of CN after RT is effective, and should be attempted. This complication is more common in smokers, and counseling intervention should result in fewer complications of CN

    2011-11-01

    Full Text Available Abstract Background Infection with human papillomavirus (HPV is associated with uterine cervical intraepithelial neoplasia (CIN and invasive cancers (ICC. Approximately 80% of ICC cases are diagnosed in under-developed countries. Vaccine development relies on knowledge of HPV genotypes characteristic of LSIL, HSIL and cancer; however, these genotypes remain poorly characterized in many African countries. To contribute to the characterization of HPV genotypes in Northeastern Tanzania, we recruited 215 women from the Reproductive Health Clinic at Kilimanjaro Christian Medical Centre. Cervical scrapes and biopsies were obtained for cytology and HPV DNA detection. Results 79 out of 215 (36.7% enrolled participants tested positive for HPV DNA, with a large proportion being multiple infections (74%. The prevalence of HPV infection increased with lesion grade (14% in controls, 67% in CIN1 cases and 88% in CIN2-3. Among ICC cases, 89% had detectable HPV. Overall, 31 HPV genotypes were detected; the three most common HPV genotypes among ICC were HPV16, 35 and 45. In addition to these genotypes, co-infection with HPV18, 31, 33, 52, 58, 68 and 82 was found in 91% of ICC. Among women with CIN2-3, HPV53, 58 and 84/83 were the most common. HPV35, 45, 53/58/59 were the most common among CIN1 cases. Conclusions In women with no evidence of cytological abnormalities, the most prevalent genotypes were HPV58 with HPV16, 35, 52, 66 and 73 occurring equally. Although numerical constraints limit inference, findings that 91% of ICC harbor only a small number of HPV genotypes suggests that prevention efforts including vaccine development or adjuvant screening should focus on these genotypes.

    Objective:To investigate the relationship between p53 protein overexpression in esophageal and cervical squamous cell cancer and their clinical radiosensitivity. Methods: The immuno-histochemical assays were done for 52 cases with esophageal and cervical squamous cell cancer. The relationship between the assay results and short-term radiotherapy was investigated. Results: p53 overer-pression was 52.38% and 35. 48% respectively, in esophageal cancer and cervical cancer;p53 over-expression in high differentiated squamous cell cancer was knver than these in moderate and poor differentiated cases(P0. 05). In the cases of cervical cancer, p53 overexpression had the less short-term effect(P0. 05).Conclusion:This study suggests that p53 gene has the certain relationship with tumor radiosensitivity.

The Mulanje Mission Hospital has offered free cervical cancer screening for eight years; however, patients primarily seek medical help for gynecologic complaints after the disease is inoperable.Methods: We investigated how women in rural Malawi make health-seeking decisions regarding cervical cancer screening using qualitative research methods. The study was conducted between May and August of 2009 in Mulanje, Malawi.Results: This study found that the primary cue to action for cervical cancer screening was symptoms of cervical cancer. Major barriers to seeking preventative screening included low knowledge levels, low perceived susceptibility and low perceived benefits from the service. Study participants did not view cervical cancer screening as critical health care. Interviews suggested that use of the service could increase if women are recruited while visiting the hospital for a different service.Conclusion: This study recommends that health care providers and health educators target aspects of perceived susceptibility among their patients, including knowledge levels and personal risk assessment. We believe that continued support and advertisement of cervical cancer screening programs along with innovative recruitment strategies will increase usage density and decrease unnecessary deaths from cervical cancer in Malawi.Keywords: cervical cancer, interviews, health care, Mulanje Mission Hospital

  2. Human Papillomavirus Induced Transformation in Cervical and Head and Neck Cancers

    Human papillomavirus (HPV) is one of the most widely publicized and researched pathogenic DNA viruses. For decades, HPV research has focused on transforming viral activities in cervical cancer. During the past 15 years, however, HPV has also emerged as a major etiological agent in cancers of the head and neck, in particular squamous cell carcinoma. Even with significant strides achieved towards the screening and treatment of cervical cancer, and preventive vaccines, cervical cancer remains the leading cause of cancer-associated deaths for women in developing countries. Furthermore, routine screens are not available for those at risk of head and neck cancer. The current expectation is that HPV vaccination will prevent not only cervical, but also head and neck cancers. In order to determine if previous cervical cancer models for HPV infection and transformation are directly applicable to head and neck cancer, clinical and molecular disease aspects must be carefully compared. In this review, we briefly discuss the cervical and head and neck cancer literature to highlight clinical and genomic commonalities. Differences in prognosis, staging and treatment, as well as comparisons of mutational profiles, viral integration patterns, and alterations in gene expression will be addressed

    MicroRNA (miRNA) expression is altered in cancer cells and is associated with the development and progression of various types of cancer. Accordingly, miRNAs may serve as diagnostic or prognostic biomarkers in cancer patients. In this study, we attempted to analyze circulating exosomal miRNA in patients with cervical cancer. Total RNA was extracted from the serum of healthy subjects, subjects with cervical intraepithelial neoplasia (CIN) and patients with cervical cancer. We first investigated miRNA expression profiles in 6 serum samples from healthy subjects and patients with cervical cancer using the miRCURY LNA microRNA array. miRNAs with significant differences in expression were validated in a larger sample set by quantitative reverse transcription-polymerase chain reaction, using TaqMan gene expression assays. The results of the miRCURY LNA microRNA array indicated that 6 of 1,223 miRNAs found in serum samples from cervical cancer patients and normal controls exhibited a >3.0-fold change in expression level in subjects with cervical cancer, with a P-value of <0.01. In a validation set (n=131) that investigated the expression of 4 of the 6 miRNAs (miR-483-5p, miR-1246, miR-1275 and miR-1290), miR-1290 was found to have significantly higher expression levels in cervical cancer samples (n=45) compared with control samples (n=31). We also found that the median levels of these miRNAs were significantly higher in subjects with cervical cancer (n=45) compared with those in subjects with CIN (n=55). Circulating miRNAs were not correlated with clinicopathological parameters. However, receiver operating characteristic curve analysis suggested that these serum miRNAs may be useful diagnostic markers in cervical cancer. The expression of circulating miR-1290 was significantly higher in the blood of cervical cancer patients compared with that in controls and may thus serve as a useful biomarker in cervical cancer diagnosis. However, larger studies are required to fully

    To our knowledge, no prior population-based study has been published wherein the primary aim was to evaluate whether an association between psychotropic drug prescription and cervical cancer exists. Herein we have conducted the first study that primarily aimed to determine the association between antidepressants use and risk of invasive cervical cancer in the general population.This is a population-based study utilizing Taiwan's National Health Insurance Research Database. We identified 26,262 cases with invasive cervical cancer and 129,490 controls. We adopted the conditional logistic regression model as the statistical method and adjusted for potential confounding factors.The prescription of selective serotonin reuptake inhibitors (SSRIs) (adjusted OR = 0.93, 95% CI = 0.84-1.04), tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), serotonin norepinephrine reuptake inhibitors (SNRIs), mirtazapine and bupropion, adjusting for cumulative dose, was not associated with an increased, or decreased, risk for invasive cervical cancer. An association between trazodone prescription and invasive cervical cancer was observed (adjusted OR = 1.22, 95% CI = 1.03-1.43).An association between the major classes of antidepressants and invasive cervical cancer was not observed herein. Our preliminary finding regarding a possible association between trazodone and cervical cancer requires replication. PMID:26496343

    Cervical cancer is one of the most frequent cancers in women worldwide. Persistent infection with a human papillomavirus (HPV) is the main cause for cervical cancer. Vaccination and Pap smear screening are the best methods for prevention of the disease. The objective of this cross-sectional study was to assess the knowledge and views of upper secondary school female students in Kuala Lumpur, Malaysia, toward prevention of cervical cancer. This study was conducted from April 2009 to September 2009 in 8 schools in Kuala Lumpur area using pre-tested and validated questionnaires. Results indicated that the respondents had low knowledge of cervical cancer and its prevention although the majority of students (80.4%) had heard about the disease. The level of knowledge of cervical cancr and its prevention was significantly higher among students from the science stream (pstudents from the art stream. Most students (69.3%) agreed to take the vaccination if the service was available in schools. A high percentage of students (82.2%) agreed that the vaccination should be compulsory to the students. In conclusion, most students had low knowledge of cervical cancer and its prevention but they had positive attitude toward vaccination and agreed that vaccination should be compulsory. Therefore, suitable educational programmes should be developed to improve the knowledge of secondary school students on the prevention of cervical cancer. PMID:23725172

    2014-04-01

    Conclusion: Cervical cancer survivors treated with radiotherapy had worse sexual functioning than did those treated with radical hysterectomy and lymph node dissection. Appropriate measures like Pelvic exercises, Yoga, vaginal dilators, vaginal cream should be used to decrease radiotherapy related side effects on sexual functioning. Cervical cancer survivors treated with surgery alone can expect overall quality of life and sexual function not unlike that of peers without a history of cancer.

  12. Medium-dose-rate intracavitary brachytherapy for cervical cancer

    The purpose of this study was to evaluate the results of medium-dose-rate (MDR) intracavitary brachytherapy (ICRT) for cervical cancer. Between May 1991 and March 2001, 80 patients with cervical cancer were treated with external radiotherapy combined with MDR-ICRT. Two patients were excluded from this study. The median age of patients was 61 years (range: 30-87 years). Seventy-five patients had pathologically proved squamous cell carcinoma, and 3 had adenocarcinoma. The patients were staged by Union Internationale Contre le Cancer (UICC) classification as follows: Stage IA (2), Stage IB (4), Stage IIA (5), Stage IIB (22), Stage IIIA (1), Stage IIIB (32), Stage IVA (5), Stage IVB (7). Median follow-up for survivor was 68 months (range: 12-131 months). The radiation therapy was based on a combination of ICRT and external pelvic irradiation. Patients with stages II, III and IVA were treated with whole-pelvic irradiation with respective total doses of 20, 30, and 40 Gy. Doses of 40, 30, 20, and 20 Gy parametrial irradiation were added with central shield pelvic irradiation for stages IB, II, III and IVA lesions respectively. For MDR-ICRT, from May 1991 to December 1995, point A dose were 40 Gy/4 fractions for stages I and II, 38 Gy/4 fractions for stage III, and 28.5 Gy/3 fractions for stage IVA. And from January 1996 to March 2001, point A dose of 36 Gy/4 fractions for stages I and II, 34 Gy/4 fractions for stage III, and 25.5 Gy/3 fractions for stage IVA. The median dose rate at point A was 1.7 Gy/hour (range: 1.3-2.2 Gy/hour). The 5-year cause-specific survival rates were 100%, 76%, 51% and 40% for stages I, II, III and IVA respectively. All patients with stage IVB died from the tumor with a median survival time of 12 months. The 5-year pelvic control rates were 100%, 88%, 69% and 40% for stages I, II, III and IVA respectively. Major late complications occurred in 2 patients (3%). One patient developed vesico- and recto-vaginal fistulae, and died of pelvic infection

The vast majority of cervical cancer-related deaths are among women that have never been screened. Prior to implementation of a screening program in Addis Ababa University-affiliated hospitals in Ethiopia, a survey was conducted to assess knowledge of cervical cancer etiology, risk factors, and screening, as well as attitudes and practices regarding cervical cancer screening among women’s health care providers.Methods: Between February and March 2012 an anonymous, self-administered survey to assess knowledge, attitudes, and practices related to cervical cancer and its prevention was distributed to 334 health care providers at three government hospitals in Addis Ababa, Ethiopia and three Family Guidance Association clinics in Awassa, Adama, and Bahir Dar. Data were analyzed using SPSS software and chi-square test was used to test differences in knowledge, attitudes, and practices across provider type.Results: Overall knowledge surrounding cervical cancer was high, although awareness of etiology and risk factors was low among nurses and midwives. Providers had no experience performing cervical cancer screening on a routine basis with <40% having performed any type of cervical cancer screening. Reported barriers to performing screening were lack of

    2011-01-01

    The purpose of this study was to evaluate women's knowledge about cervical cancer, Pap smears, and human papilloma virus in relation to their cervical cancer screening behavior. This hospital-based study was conducted with a sample of 200 women: 100 women screened in the last three years and 100 non-screened women who attended a hospital located in the metropolitan area of Buenos Aires, between September 2008 and February 2009. Women at the hospital were surveyed using a structured questionnaire. Multiple logistic regression models were used to evaluate the relation of women's knowledge about Pap smears to screening behavior, controlling for socio-demographic characteristics. Of the women who had been screened, 49% compared to 73% of those not screened had inadequate knowledge about Pap smears (P = 0.001), and 47% of screened and 30% of non-screened women reported that they had ever heard about human papilloma virus (P = 0.013). In multivariate analysis, having adequate knowledge about Pap smears (odds ratio: 2.6 or 95%, confidence interval: 1.4-4.8) having health insurance (odds ratio: 2.6 or 95%, confidence interval: 1.1-6.4) and being married (odds ratio: 1.8 or 95%, confidence interval: 1.1-3.4) were the factors related to being screened in the previous three years. Knowledge was related to screening. Comprehensive educational approaches may enhance screening for cervical cancer prevention. PMID:21391162

    Full Text Available Comprehensive study for optimization of parameters of photodynamic action with fotoditazin in patients with tumor and pre-tumor cervical diseases was conducted. The study included 52 female patients: pre-invasive cervical diseases were diagnosed in 34 (CIN I – in 9, CIN II – in 13, CIN III – in 12, cervical cancer – in 11 (8 had squamous cell cancer, 3 – adenocarcinoma of cervical canal, chronic cervicitis – in 7. The study agent in the form of 0,5% gel was applied on cervix in dose of 1 ml. To detect optimal interval between gel application and conduction of photodynamic therapy dynamics of accumulation and elimination of photosensitizer by means of its fl uorescence was studied. Fotoditazin was shown to have good accumulation in pathological tissues. The maximal agent accumulation was noticed in 30 min, continued about 15 min, and then gradually decreased. Maximal fl uorescence of photosensitizer was observed in foci of malignant tumor and severe intraepithelial neoplasia. To detect optimal light dose for irradiation cytological study of cell smear from specimen after light exposure with different light doses was performed. The minimal light dose necessary for activation of photochemical reaction pathway was 100 J/cm2, and optimal – 250 J/cm2. This dose allowed to destroy all atypical cells in the area of light exposure after application of gel fotoditazin. According to obtain data we suppose that the most effi cient regimen of photodynamic therapy with local application of fotoditazin-gel for treating dysplasia and pre-invasive cervical cancer was a dose of laser irradiation of 250 J/cm2 with duration of application of 30–45 min.

    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.

    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...... common HPV types in women with HG-CIN were HPV16/33/31 (59.9/10.5/9.0%) and in ICC were HPV16/18/45 (63.3/15.2/5.3%). In squamous cell carcinomas, HPV16/18/33 were most frequent (66.2/10.8/5.3%), and in adenocarcinomas, HPV16/18/45 (54.2/40.4/8.3%). The prevalence of HPV16/18/45 was 1.1/3.5/2.5 times...

  18. Long-Term Survival and Risk of Second Cancers After Radiotherapy for Cervical Cancer

    Purpose: To evaluate the risk of second cancers after cervical cancer treated with radiotherapy for Asian populations. Methods and Materials: We reviewed 2,167 patients with cervical cancer undergoing radiotherapy between 1961 and 1986. Intracavitary brachytherapy was performed with high-dose rate source (82%) or low-dose rate source (12%). Relative risk (RR), absolute excess risk (AR), and cumulative risk of second cancer were calculated using the Japanese disease expectancy table. For 1,031 patients, the impact of smoking habit on the increasing risk of second cancer was also evaluated. Results: The total number of person-years of follow-up was 25,771, with 60 patients being lost to follow-up. Among the 2,167 patients, 1,063 (49%) survived more than 10 years. Second cancers were observed in 210 patients, representing a significant 1.2-fold risk (95% confidence interval [CI], 1.1-1.4) of developing second cancer compared with the general population, 1.6% excess risk per person per decade of follow-up, and elevating cumulative risk up to 23.8% (95% CI, 20.3-27.3) at 30 years after radiotherapy. The RR of second cancer was 1.6-fold for patients with the smoking habit and 1.4-fold for those without. Conclusions: Small but significant increased risk of second cancer was observed among Japanese women with cervical cancer mainly treated with high-dose rate brachytherapy. Considering the fact that about half of the patients survived more than 10 years, the benefit of radiotherapy outweighs the risk of developing second cancer

  19. Radiation Dose and Subsequent Risk for Stomach Cancer in Long-term Survivors of Cervical Cancer

    Purpose: To assess the dose–response relationship for stomach cancer after radiation therapy for cervical cancer. Methods and Materials: We conducted a nested, matched case–control study of 201 cases and 378 controls among 53,547 5-year survivors of cervical cancer diagnosed from 1943 to 1995, from 5 international, population-based cancer registries. We estimated individual radiation doses to the site of the stomach cancer for all cases and to corresponding sites for the matched controls (overall mean stomach tumor dose, 2.56 Gy, range 0.03-46.1 and after parallel opposed pelvic fields, 1.63 Gy, range 0.12-6.3). Results: More than 90% of women received radiation therapy, mostly with external beam therapy in combination with brachytherapy. Stomach cancer risk was nonsignificantly increased (odds ratio 1.27-2.28) for women receiving between 0.5 and 4.9 Gy to the stomach cancer site and significantly increased at doses ≥5 Gy (odds ratio 4.20, 95% confidence interval 1.41-13.4, Ptrend=.047) compared with nonirradiated women. A highly significant radiation dose–response relationship was evident when analyses were restricted to the 131 cases (251 controls) whose stomach cancer was located in the middle and lower portions of the stomach (Ptrend=.003), whereas there was no indication of increasing risk with increasing dose for 30 cases (57 controls) whose cancer was located in the upper stomach (Ptrend=.23). Conclusions: Our findings show for the first time a significant linear dose–response relationship for risk of stomach cancer in long-term survivors of cervical cancer

  20. Sperm protein 17 is highly expressed in endometrial and cervical cancers

    Sperm protein 17 (Sp17) is a highly conserved mammalian protein in the testis and spermatozoa and has been characterized as a tumor-associated antigen in a variety of human malignancies. Many studies have examined the role of Sp17 in tumorigenesis and the migration of malignant cells. It has been proposed as a useful target for tumor-vaccine strategies and a novel marker to define tumor subsets and predict drug response. This study aimed to investigate the expression of Sp17 in endometrial and cervical cancer specimens, its possible correlation with the pathological characteristics, and its value in the diagnosis and immunotherapy of the related cancers. The monoclonal antibodies against human Sp17 were produced as reagents for the analysis and immunohistochemistry was used to study two major kinds of paraffin-embedded gynecological cancer specimens, including 50 cases of endometrial cancer (44 adenous and 6 adenosquamous) and 31 cases of cervical cancer (15 adenous and 16 squamous). Normal peripheral endometrial and cervical tissues were used as controls. Sp17 was found in 66% (33/50) of the patients with endometrial cancer and 61% (19/31) of those with cervical cancer. Its expression was found in a heterogeneous pattern in the cancer tissues. The expression was not correlated with the histological subtype and grade of malignancy, but the staining patterns were different in endometrial and cervical cancers. The hyperplastic glands were positive for Sp17 in the normal peripheral endometrial and cervical tissues in 10% (8/81) of the patients. Sp17 is highly expressed in human endometrial and cervical cancers in a heterogeneous pattern. Although the expression frequency of Sp17 is not correlated with the histological subtype, the staining pattern may help to define endometrial and cervical cancers. Sp17 targeted immunotherapy of tumors needs more accurate validation

    Full Text Available Background: Cervical cancer being a major cause of morbidity and mortality in women in developing countries, its awareness is essential. Aim: The aim of this study is to assess the knowledge, attitude and practices of women regarding the basic screening test for detection of cancer cervix. Settings and Design: Population based cross-sectional study. Materials and Methods: Cross-sectional prospective study was conducted. Information from consenting participants (450 was collected using structured questionnaire. Answers were described in terms of knowledge, attitude and practice and their respective adequacy with respect to Papanicolaou (Pap test, the most common test used for early detection of cervical cancer. Adequacy was compared between the categories of socio demographic and clinical variables. Statistical Analysis: The data collected was analyzed using statistical package (SPSS version 18.0. Adequacy was compared between the categories of the control variables by χ2 test with a 5% significance level. Results: Knowledge, attitude and practices regarding Pap test were adequate in 32.7%, 18.2% and 7.3% of women respectively. Major impediment to adequate practice was lack of request by physician. Knowledge, attitudes and practices were found to increase significantly with increasing age and education. Conclusion: Effective information, education and communication strategies are required to improve the level of awareness of public. Health-care professional should be proactive in imparting knowledge at every opportunity.

    Full Text Available With improved overall survival of cervical cancer patients, the importance of the quality of life (QOL is increasingly recognized. This study was conducted to compare the QOL of women with different stage cervical cancer before and after treatment to facilitate improved cervical cancer prevention and treatment. We used the generic Medical Outcomes Study Short Form-36 (MOS SF-36 to collect QOL information. Based on SF-36, we interviewed cervical cancer patients at West China Second Affiliated Hospital and Sichuan Cancer Hospital between May 2010 and January 2011. A total of 92 patients with precancerous lesions, 93 with early cancer, and 35 with advanced cancer responded to our survey. Average physical component summary (PCS scores were significantly different between the three groups at every time point (P < 0.05. Average mental component summary (MCS scores were significantly different between the three groups after treatment (P < 0.05. Average PCS and MCS scores increased gradually from the pretreatment to posttreatment period for patients with precancerous lesions. However, they reached the lowest at 1 month after treatment for patients with early and advanced cancers and rebounded between 1 and 6 months after treatment. Our results indicate that patients with precancerous lesions and early cervical cancer show better overall QOL than do those with advanced cervical cancer. Additionally, patients with early cancer recover more quickly than do those with advanced cancer in terms of both physical and mental functions. Thus, early detection and treatment initiatives may improve the QOL for patients with precancerous lesions and cervical cancer.

To determine whether ovarian radiation affects serum hormone levels differently from surgical removal of the ovaries, serum estradiol, estrone, testosterone and androstenedione were evaluated by radioimmunoassay in 320 women (203 irradiated and 117 nonirradiated) from six US clinics participating in a large international cohort study of women treated for cervical cancer since the 1960's. Overall, estradiol levels were similar for both treatment groups, while estrone, testosterone and androstenedione levels were somewhat lower in irradiated women than in nonirradiated women after adjustment for year of birth. Notably, among women in both groups whose treatment included bilateral oophorectomy, irradiated women consistently had lower levels of androstenedione, testosterone and estrone but similar levels of estradiol

  8. Adjuvanticity of vitamin A in advanced irradiated cervical cancer

    For treatment of patients with inoperable cervical cancer (FIGO III) a randomized trial has been initiated. Patients were randomized to receive either conventional irradiation therapy together with vitamin A palmitate (1.5 mill. I.U./day; total dose: 30 mill. I.U.), applied orally, or irradiation alone. When lymphocyte reactivity to PHA (maximum response during therapy) was compared within the groups, it was found, that 66% of the patients who received irradiation combined with vitamin A palmitate, showed an increase in their blastogenic response, while in irradiated patients without vitamin A palmitate a response was seen only in 33%. This difference being statistically significant in comparison to pretreatment values. From immunological data it can be concluded, that vitamin A has an effect on functional response on T-cells. Concerning the clinical outcome, after an observation period of 12 months relapse rates were lower in the vitamin A group, but not significantly reduced. Therefore further follow up is warranted.

    Valente, Kari; Montgomery, Kathleen; Schultenover, Stephen; Desouki, Mohamed Mokhtar

    2016-04-01

    Vulvar lymphangioma circumscriptum (LC) is a rare entity which may present as a painful, warty lesion. In contrast to the congenital form, which occurs in children, the acquired form arises in older adults and may be associated with infection, Crohn's disease, or prior pelvic/regional surgery. We present a case of acquired LC of the vulva in a 55-year-old woman who presented with a 3-4 year history of vulvar pain following chemotherapy, radiation, and brachytherapy for cervical cancer. Vulvar shave biopsies followed by excision revealed a thickened dermis with epidermal hyperkeratosis, parakeratosis, elongated rete ridges and dilated lymphatic channels containing eosinophilic material and scattered thrombi. The differential diagnosis for this unusual lesion includes more common conditions such as condyloma acuminatum, fungating squamous cell carcinoma and molluscum contagiosum. It is important to recognize the clinical presentation as well as the distinct histological appearance of this rare benign entity. PMID:27331134

  10. Genital HPV: links to cervical cancer, treatment, and prevention.

    Perez, L A

    2001-01-01

    Human papillomavirus is one of the most prevalent sexually transmitted viruses. It consists of over 230 different subtypes and infects the squamous epithelial cells in humans producing cutaneous, mucosal, and epidermodysplasia verruciformis type infections. There are several risk factors for human papillomavirus infections. These include a sexually active life-style beginning at a young age, having multiple lifetime sex partners, having sex with a partner with genital warts, and long term oral contraceptive use. Approximately 80% of sexually active individuals acquire the virus in their lifetime. Clinical and laboratory detection of the virus consists of macroscopic, serologic, and molecular techniques. Although removal of the lesions is preferable, treatment of human papillomavirus infections may include cryotherapy, loop electrosurgical excision procedure, laser surgery, and drug therapy. Certain human papillomavirus subtypes, particularly human papillomavirus 16, have been linked to cervical cancer, therefore, prophylactic and therapeutic vaccines are currently being developed to prevent or fight the virus.

    Full Text Available Aswathy Sreedevi, Reshma Javed, Avani Dinesh Community Medicine, AIMS, Kochi, Amrita Vishwa Vidyapeetham, Kerala, India Abstract: Cervical cancer is on the declining trend in India according to the population-based registries; yet it continues to be a major public health problem for women in India. Multifactorial causation, potential for prevention, and the sheer threat it poses make cervical cancer an important disease for in-depth studies, as has been attempted by this paper. This paper attempts to review the available knowledge regarding the epidemiology and pattern of cervical cancer; types of HPV (human papilloma virus prevalent among cervical cancer patients and among women in general, high-risk groups such as commercial sex workers, and HIV (human immunodeficiency virus-positive women; and the role of the national program on cancer in control efforts. The peak age of incidence of cervical cancer is 55–59 years, and a considerable proportion of women report in the late stages of disease. Specific types of oncogenic HPV-16, 18 have been identified in patients with cervical cancer. Other epidemiological risk factors are early age at marriage, multiple sexual partners, multiple pregnancies, poor genital hygiene, malnutrition, use of oral contraceptives, and lack of awareness. A multipronged approach is necessary which can target areas of high prevalence identified by registries with a combination of behavior change communication exercises and routine early screening with VIA. Sensitizing the people of the area, including menfolk, is necessary to increase uptake levels. Vaccination against types 16 and 18 can also be undertaken after taking into confidence all stakeholders, including the parents of adolescent girls. Preventing and treating cervical cancer and reducing the burden are possible by targeting resources to the areas with high prevalence.

    2015-01-01

    Full Text Available Background: Cervical cancer is the second most common cancer among women worldwide and is the leading cause of deaths in developing countries. Despite the strong evidence that cervical cancer screening results in decreased mortality from this disease, the uptake for cervical screening among Jamaican women remains low. Aims : This study was carried out to identify factors associated with Jamaican women′s decisions to screen for cervical cancer. Materials and Methods: Cross-sectional descriptive study of 403 women aged 19 years and older from Portland, Jamaica. An interviewer-administered questionnaire assessed the women′s cervical cancer screening history, as well as their knowledge, attitudes, and practices regarding the disease and screening. Results: Of the 403 women interviewed, 66% had a Papanicolaou (Pap smear and only 16% had a Pap test within the past year. Significant predicators of uptake of screening were being married, age, parity, discussing cancer with health provider, perception of consequences of not having a Pap smear, and knowing a person with cervical cancer. Women who did not know where to go for a Pap smear were 85% less likely to have been screened (prevalence odds ratio (POR: 0.15, 95% confidence interval (CI: 0.04, 0.52. Conclusions: This study showed suboptimal uptake of cervical cancer screening among Jamaican women. Multipronged approaches are needed to address barriers to screening, as well as identify and support conditions that encourage women′s use of reproductive health services, thereby reducing incidence and mortality rates from cervical cancer.

    Full Text Available Abstract Background Secreted protein acidic and rich in cysteine (SPARC, a calcium-binding matricellular glycoprotein, is implicated in the progressions of some cancers. However, no information has been available to date regarding the function of SPARC in cervical cancer cell growth and metastasis. Methods In this study, we isolated and established high invasive subclones and low invasive subclones from human cervical cancer cell lines HeLa and SiHa by the limited dilution method. Real-time q-RT-PCR, Western Blot and ICC were performed to investigate SPARC mRNA and protein expressions in high invasive subclones and low invasive subclones. Then lentivirus vector with SPARC shRNA was constructed and infected the highly invasive subclones. Real-time q-RT-PCR, Western Blot and ICC were also performed to investigate the changes of SPARC expression after viral infection. In functional assays, effects of SPARC knockdown on the biological behaviors of cervical cancer cells were investigated. The mechanisms of SPARC in cervical cancer proliferation, apoptosis and invasion were also researched. Results SPARC was over-expressed in the highly invasive subclones compared with the low invasive subclones. Knockdown of SPARC significantly suppressed cervical cancer cell proliferation, and induced cell cycle arrest at the G1/G0 phase through the p53/p21 pathway, also caused cell apoptosis accompanied by the decreased ratio of Bcl-2/Bax, and inhibited cell invasion and metastasis accompanied by down-regulated MMP2 and MMP9 expressions and up-regulated E-cadherin expression. Conclusion SPARC is related to the invasive phenotype of cervical cancer cells. Knockdown of SPARC significantly suppresses cervical cancer cell proliferation, induces cell apoptosis and inhibits cell invasion and metastasis. SPARC as a promoter improves cervical cancer cell growth and metastasis.

  15. Is 0.6T Magnetic Resonance Mammography Adequate in the Detection of Breast Cancer?

    Purpose: To evaluate whether relevant diagnostic information can be achieved when using magnetic resonance mammography (MRM) on mid-field as a supplement to conventional imaging and clinical examination in women with primary breast cancer. Material and Methods: 30 women (55 breasts containing 49 malignant tumors) planned for uni- or bilateral mastectomy were examined with dynamic MRM on mid-field, 0.6T. The women were examined with mammography (M) and ultrasonography (US) prior to MRM. The descriptions of the conventional examinations were evaluated retrospectively, whereas the MRM was evaluated prospectively, with knowledge of the M+US findings. Imaging findings suggesting malignancy were registered and correlated with pathology after mastectomy. A home-made rating system for evaluation of the detected lesions was tested. Results: MRM detected seven additional malignant tumors, failed to detect three lesions and characterized four as gray-zone lesions according to the rating system. Sensitivity of finding the tumors with M+US was 79.0%, with a PPV for malignant tumors of 84.4%. One breast in which MRM found a malignant tumor had not initially been examined with US. Sensitivity with MRM was 91.6%, with a positive predictive value of malignant tumors of 97.7%. Conclusion: MRM on mid-field seems to improve the detection of cancers when used as a supplement to M+US in women with primary breast cancer. We believe that the results are fair compared to MRM on high-field, although further research and refinement are needed

    2015-01-01

    Severely immunosuppressed individuals have a strongly increased risk of cervical cancer. In patients with autoimmune diseases (AID), who have defects in their immune system and receive immunosuppressants, the risk of cervical cancer is less clear. We conducted a cohort study, using Danish...... nationwide population-based registers including information on AID diagnoses, immunosuppressant intake, cervical screening participation, and cervical cancer incidence. Standardized incidence ratios (SIR) were computed to compare the risk of cervical cancer in AID patients to that of the general population....... Hazard ratios (HR) from time-dependent Cox models stratified by AID were used to explore the effect of the most frequently used immunosuppressants, taking into account potential dose-response relationships and lag times between drug exposure and cervical cancer development.

  17. A comprehensive review on host genetic susceptibility to human papillomavirus infection and progression to cervical cancer

    Koushik Chattopadhyay

    2011-01-01

    Full Text Available Cervical cancer is the second most common cancer in women worldwide. This is caused by oncogenic types of human papillomavirus (HPV infection. Although large numbers of young sexually active women get HPV-infected, only a small fraction develop cervical cancer. This points to different co-factors for regression of HPV infection or progression to cervical cancer. Host genetic factors play an important role in the outcome of such complex or multifactor diseases such as cervical cancer and are also known to regulate the rate of disease progression. The aim of this review is to compile the advances in the field of host genetics of cervical cancer. MEDLINE database was searched using the terms, ′HPV′, ′cervical′, ′CIN′, ′polymorphism(s′, ′cervical′ + FNx01the name of the geneFNx01 and ′HPV′ + FNx01the name of the geneFNx01. This review focuses on the major host genes reported to affect the progression to cervical cancer in HPV infected individuals.

  18. Increased risk of ischemic stroke in cervical cancer patients: a nationwide population-based study

    Increased risk of ischemic stroke has been validated for several cancers, but limited study evaluated this risk in cervical cancer patients. Our study aimed to evaluate the risk of ischemic stroke in cervical cancer patients. The study analyzed data from the 2003 to 2008 National Health Insurance Research Database (NHIRD) provided by the National Health Research Institutes in Taiwan. Totally, 893 cervical cancer patients after radiotherapy and 1786 appendectomy patients were eligible. The Kaplan-Meier method and the Cox proportional hazards model were used to assess the risk of ischemic stroke. The 5-year cumulative risk of ischemic stroke was significantly higher for the cervical cancer group than for the control group (7.8% vs 5.1%; p <0.005). The risk of stroke was higher in younger (age <51 years) than in older (age ≥51 years) cervical cancer patients (HR = 2.73, p = 0.04; HR = 1.37, p = 0.07) and in patients with more than two comorbid risk factors (5 years cumulative stroke rate of two comorbidities: 15% compared to no comorbidities: 4%). These study demonstrated cervical cancer patients had a higher risk of ischemic stroke than the general population, especially in younger patients. Strategies to reduce this risk should be assessed

  19. Knowledge and acceptability of human papillomavirus vaccination and cervical cancer screening among women in Karnataka, India.

    Montgomery, Martha P; Dune, Tanaka; Shetty, Prasanna K; Shetty, Avinash K

    2015-03-01

    Cervical cancer is the leading cause of cancer-related mortality among women in India; however, participation in prevention and screening is low and the reasons for this are not well understood. In a cross-sectional survey in August 2008, 202 healthy women in Karnataka, India completed a questionnaire regarding knowledge, attitudes, and practices related to human papillomavirus (HPV) and cervical cancer. Factors associated with vaccination and Papanicolau (Pap) smear screening acceptance were explored. Thirty-six percent of women had heard of HPV while 15% had heard of cervical cancer. Five percent of women reported ever having a Pap smear, and 4% of women felt at risk of HPV infection. Forty-six percent of women were accepting of vaccination, but fewer (21%) were willing to have a Pap smear. Overall, knowledge related to HPV and cervical cancer topics was low. Women with negative attitudes toward HPV infection were 5.3 (95% confidence interval (CI) 2.8-10) times more likely to accept vaccination but were not significantly more likely to accept Pap smear (odds ratio 1.5, 95% CI 0.7-3.0). Cost and a low level of perceived risk were the most frequent factors cited as potential barriers. Improving awareness of HPV and cervical cancer through health care providers in addition to increasing access to vaccination and screening through government-sponsored programs may be feasible and effective methods to reduce cervical cancer burden in India.

  20. Predictors of cervical cancer screening adherence in the United States: a systematic review.

    Limmer, Karen; LoBiondo-Wood, Geri; Dains, Joyce

    2014-01-01

    Cervical cancer incidence rates have decreased dramatically since the implementation of the Papanicolaou (Pap) smear. Nevertheless, the American Cancer Society (ACS) estimates for 2013 predicted more than 12,000 new cases of cervical cancer in the United States. Given that some subpopulations in the United States are at a higher risk for cervical cancer than others, efforts to increase screening adherence are warranted. Many studies have explored the demographics of underscreened women, but no systematic reviews of screening demographics in adult US women were identified in the past 10 years, after release of the 2002 ACS cervical cancer screening guidelines. Knowledge of adherence to these guidelines becomes important as new guidelines were developed and released in 2012. The purpose of this systematic review of relevant studies was to identify factors that predict the use of cervical cancer screening in US women. Variables found to be significantly associated with adherence to screening included education, financial status, acculturation, psychosocial issues, and marital status. Using this information, nurse practitioners and other providers can target specific at-risk populations to increase screening by educating women about the need for cervical cancer screening and ensuring access to methods for prevention and early detection of the disease.

  1. Accelerating the reduction in cervical cancer: what can we learn from the Safe Motherhood movement?

    Tsu, Vivien D; Jeronimo, Jose

    2013-10-01

    As we move toward the post-2015 development agenda, we should reflect on the accomplishments of the Safe Motherhood movement and derive potential lessons to strengthen programs to reduce the burden of cervical cancer. Five key areas have been the focus of attention over the years: definition of the magnitude and distribution of maternal mortality; identification of effective and feasible clinical solutions; advocacy to increase attention, resources, and commitment; leadership through international coalitions; and development of a framework for accountability, with targets and indicators. While efforts have been made in each of these areas for cervical cancer prevention, progress has been constrained by inadequate resources. Data are of variable quality, with few cancer registries in the countries where cervical cancer is most prevalent. There has been substantial progress in identifying feasible and effective clinical and programmatic interventions, and a growing consensus around meaningful indicators. Advocacy on behalf of cervical cancer prevention has been gaining momentum but leadership is still fragmented. With so many of the basic elements for cervical cancer prevention in place, we must use the lessons learned from the Safe Motherhood movement to accelerate the pace of scaling-up cervical cancer prevention activities, saving millions of women's lives in the next decade.

    Biomechanical properties are key to many cellular functions such as cell division and cell motility and thus are crucial in the development and understanding of several diseases, for instance cancer. The mechanics of the cellular cytoskeleton have been extensively characterized in cells and artificial systems. The rigidity of the plasma membrane, with the exception of red blood cells, is unknown and membrane rigidity measurements only exist for vesicles composed of a few synthetic lipids. In this study, thermal fluctuations of giant plasma membrane vesicles (GPMVs) directly derived from the plasma membranes of primary breast and cervical cells, as well as breast cell lines, are analyzed. Cell blebs or GPMVs were studied via thermal membrane fluctuations and mass spectrometry. It will be shown that cancer cell membranes are significantly softer than their non-malignant counterparts. This can be attributed to a loss of fluid raft forming lipids in malignant cells. These results indicate that the reduction of membrane rigidity promotes aggressive blebbing motion in invasive cancer cells.

  5. Cervical cancer survival prediction using hybrid of SMOTE, CART and smooth support vector machine

    Purnami, S. W.; Khasanah, P. M.; Sumartini, S. H.; Chosuvivatwong, V.; Sriplung, H.

    2016-04-01

    According to the WHO, every two minutes there is one patient who died from cervical cancer. The high mortality rate is due to the lack of awareness of women for early detection. There are several factors that supposedly influence the survival of cervical cancer patients, including age, anemia status, stage, type of treatment, complications and secondary disease. This study wants to classify/predict cervical cancer survival based on those factors. Various classifications methods: classification and regression tree (CART), smooth support vector machine (SSVM), three order spline SSVM (TSSVM) were used. Since the data of cervical cancer are imbalanced, synthetic minority oversampling technique (SMOTE) is used for handling imbalanced dataset. Performances of these methods are evaluated using accuracy, sensitivity and specificity. Results of this study show that balancing data using SMOTE as preprocessing can improve performance of classification. The SMOTE-SSVM method provided better result than SMOTE-TSSVM and SMOTE-CART.

After the training, the participants felt confident about their ability to counsel and screen women for cervical cancer.

  8. Perception of cervical cancer screening among Japanese university students who have never had a pap smear: a qualitative study.

    Oshima, Sumiko; Maezawa, Masaji

    2013-01-01

    This study aimed to explore attitudes towards cervical cancer screening among Japanese university students who had never had a Pap smear. Four focus-group discussions, each with 15 female university students, took place in November and December 2009. Discussions were recorded and transcripts were analyzed to extract attitudes of young women towards cervical cancer screening. The four themes that emerged were: i) a low sense of reality about cervical cancer; ii) a lack of knowledge about both cervical cancer and Pap smears; iii) a lack of motivation to get screened, and iv) a reluctance to visit the gynecologist. Participants who were interested in undergoing screening for cervical cancer cited the influence of conversations with friends and family, a diagnosis of cancer within their family, and relevant information from the media. The results indicate the importance of getting young women more interested in cervical cancer screening and overcoming their tendency to avoid visiting a gynecologist. PMID:23991995

    Despite low breast and cervical cancer screening levels among Hmong women in the U.S. reported in the literature, understanding of the barriers to screening for Hmong women is limited. Health literacy issues may influence screening behavior for this population. This qualitative study explored sources of information about breast and cervical cancer including screening and identified barriers to seeking such information for Hmong women and men. We conducted semi-structured, in-depth interviews ...

    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.

    2016-01-01

    This research investigates the interrelationships between cancer risk perceptions (absolute and comparative risk perceptions), cancer worry, and cervical cancer screening. Using a nationally representative survey data set (N = 2,304) from the 2012 Health Information National Trends Survey Circle 1, we found that although neither absolute risk perceptions nor comparative risk perceptions exerted a direct impact on women's compliance with the cervical cancer screening recommendation (i.e., that women ages 21 to 65 obtain Pap smear every 3 years; U.S. Preventive Services Task Force, 2012 ), both types of risk perceptions had an indirect effect on cervical cancer screening through the mediation of cancer worry. These results suggest a primal role of affect in health decision making. Implications of the findings for cancer risk communication are discussed. PMID:26312444

  6. Cervical cancer and human papillomavirus: Epidemiological evidence and perspectives for prevention

    MUÑOZ NUBIA

    1997-01-01

    Full Text Available Cervical cancer is a major public health problem, as it is the second most common cancer in women world-wide after breast cancer. About 80% of the half a million cases estimated to occur annually in the world, occur in developing countries. The epidemiological evidence linking human papillomavirus (HPV to cervical cancer is reviewed. It is concluded that over 90% of cervical cancers can be attributed to certain HPV types. HPV 16 accounts for the highest proportion (50% followed by HPV 18 (12%, HPV 45 (8% and HPV 31 (5%. The associations with these HPV types are very b and consistent with odds ratios over 15 in all case-control studies in high- and low-risk countries for cervical cancer. However, HPV is not a sufficient cause of this malignancy; certain cofactors are necessary for a proportion of HPV persistent infections to eventually progress to cancer. These include host factors such as histocompatibilidad types and immunological response, hormonal influences and infections with other sexually transmitted agents such as Chlamydia trachomatis. In addition, results from our studies carried out in Spain and Colombia support the hypothesis that male carriers of HPV play an important role in the development of cervical cancer in their wives. The recognition of the central role of HPV in cervical cancer has far-reaching implications for the primary and secondary prevention of this malignancy. Prophylactic and therapeutic HPV vaccines are now under development and HPV typing is being integrated into screening programmes in pilot studies in a few developed countries. In developing countries, well conducted conventional screening programmes remain the best approach for the control of cervical cancer until a safe and efficient HPV vaccine can be used in the general population.

    Background Image-guided adaptive proton therapy (IGAPT) can potentially be applied to take into account interfraction motion while limiting organ at risk (OAR) dose in cervical cancer radiation therapy (RT). In this study, the potential dosimetric advantages of IGAPT compared with photon-based image-guided adaptive RT (IGART) were investigated. Material and methods For 13 cervical cancer patients, full and empty bladder planning computed tomography (CT) images and weekly CTs were acquired. Based on both primary clinical target volumes (pCTVs) [i.e. gross tumor volume (GTV), cervix, corpus-uterus and upper part of the vagina] on planning CTs, the pretreatment observed full range primary internal target volume (pITV) was interpolated to derive pITV subranges. Given corresponding ITVs (i.e. pITVs including lymph nodes), patient-specific photon and proton plan libraries were generated. Using all weekly CTs, IGART and IGAPT treatments were simulated by selecting library plans and recalculating the dose. For each recalculated IGART and IGAPT fraction, CTV (i.e. pCTV including lymph nodes) coverage was assessed and differences in fractionated substitutes of dose-volume histogram (DVH) parameters (V15Gy, V30Gy, V45Gy, Dmean, D2cc) for bladder, bowel and rectum were tested for significance (Wilcoxon signed-rank test). Also, differences in toxicity-related DVH parameters (rectum V30Gy, bowel V45Gy) were approximated based on accumulated dose distributions. Results In 92% (96%) of all recalculated IGAPT (IGART) fractions adequate CTV coverage (V95% >98%) was obtained. All dose parameters for bladder, bowel and rectum, except the fractionated substitute for rectum V45Gy, were improved using IGAPT. Also, IGAPT reduced the mean dose to bowel, bladder and rectum significantly (p photon-based IGART, IGAPT maintains target coverage while significant dose reductions for the bladder, bowel and rectum can be achieved.

    2011-06-01

    Full Text Available Abstract Human Papillomavirus (HPV is the most common cause of cervical cancer. Cervical cancer being the second most common cancer after lung cancer, affecting women of different age groups; has a prevalence of about 20% in young sexually active women. Among different types of HPV, HPV16 the major strain causing this cancer and is sexually transmitted had been unnoticed for decades. Keeping in mind the multiple risk factors related with cervical cancer such as early age sexual activities, teenage pregnancies, smoking, use of oral contraceptives, having multiple sex partners, hormone replacement therapies and various other unknown factors lead to the onset of the disease. Awareness for various diagnostic procedures such as Pap smears screening prove to be an effective way in eradicating the oncogenic potential of HPV.

    Cervical cancer cells exhibit an increased requirement for ubiquitin-dependent protein degradation associated with an elevated metabolic turnover rate. Ubiquitin, which is a small, highly conserved protein expressed in all eukaryotic cells, can be covalently linked to certain target proteins to mark them for degradation by the ubiquitin-proteasome system. Previous studies highlight the essential role of Ubiquitin B (UbB) and UbB-dependent proteasomal protein degradation in histone deacetylase...

    Lee, Sung Jong; Yang, Andrew; Wu, T C; Hung, Chien Fu

    2016-09-01

    Cervical cancer is the fourth most lethal women's cancer worldwide. Current treatments against cervical cancer include surgery, radiotherapy, chemotherapy, and anti-angiogenic agents. However, despite the various treatments utilized for the treatment of cervical cancer, its disease burden remains a global issue. Persistent infection of human papillomavirus (HPV) has been identified as an essential step of pathogenesis of cervical cancer and many other cancers, and nation-wide HPV screening as well as preventative HPV vaccination program have been introduced globally. However, even though the commercially available prophylactic HPV vaccines, Gardasil (Merck) and Cervarix (GlaxoSmithKline), are effective in blocking the entry of HPV into the epithelium of cervix through generation of HPV-specific neutralizing antibodies, they cannot eliminate the pre-existing HPV infection. For these reason, other immunotherapeutic options against HPV-associated diseases, including therapeutic vaccines, have been continuously explored. Therapeutic HPV vaccines enhance cell-mediated immunity targeting HPV E6 and E7 antigens by modulating primarily dendritic cells and cytotoxic T lymphocyte. Our review will cover various therapeutic vaccines in development for the treatment of HPV-associated lesions and cancers. Furthermore, we will discuss the potential of immune checkpoint inhibitors that have recently been adopted and tested for their treatment efficacy against HPV-induced cervical cancer. PMID:27329199

  12. Postoperative radiation for cervical cancer with pathologic risk factors

    Purpose: To examine the efficacy of postoperative radiation therapy for early-stage cervical cancer with pathologic risk factors. Methods and Materials: We reviewed the charts of 83 patients who received postoperative radiation therapy at our facility from March 1980 to November 1993 for early stage cervix cancer with positive surgical margins, positive pelvic or periaortic lymph nodes, lymphovascular space invasion, deep invasion, or for disease discovered incidentally at simple hysterectomy. Twenty-eight patients received low dose rate (LDR) intracavitary radiation with or without external beam pelvic irradiation and 55 patients received external beam pelvic irradiation with high dose rate (HDR) intracavitary implants. Of these 83 patients, 66 were evaluable--20 LDR and 46 HDR patients. All patients received 45-50 Gy external beam irradiation and 20 Gy LDR equivalent intracavitary irradiation prescribed to 0.5 cm below the mucosa. Ninety percent of the LDR group and 92% of the HDR group completed treatment within < 56 days. Treatment-related toxicities were scored according to the GOG toxicity scale. Mean and median follow-up times were 101 months and 111 months (3-172 months) for the LDR group and 42 and 40 months (3-98 months) for the HDR group. Results: The 5-year disease-free survival was 89% for the LDR group and 72% for the HDR group. Local control was observed in 90% (18 out of 20) of the LDR patients and 89% (41 out of 46) of the HDR patients for an overall local control rate of 89.5%. Two of 20 LDR patients (10%) experienced recurrence (two pelvic with distant metastasis). Nine of 46 HDR patients (22%) had recurrence of disease (three pelvic, four distant metastasis, and two pelvic with distant metastasis). In the HDR group, 6 out of 16 (38%) with positive lymph nodes died of disease whereas, 27 out of 30 (90%) of the patients with negative lymph nodes remain free of disease. Three of 20 (15%) LDR patients and 4 out of 46 (9%) HDR patients experienced

    2011-10-01

    Full Text Available Abstract Background Cervical cancer, although largely preventable, remains the most common cause of cancer mortality among women in low-resource countries. The objective of this study was to assess knowledge and awareness of cervical cancer prevention among Cameroonian healthcare workers. Methods A cross-sectional self-administered questionnaire in 5 parts with 46 items regarding cervical cancer etiology and prevention was addressed to healthcare workers in six hospitals of Yaoundé, Cameroon. The investigators enlisted heads of nursing and midwifery to distribute questionnaires to their staff, recruited doctors individually, in hospitals and during conferences and distributed questionnaires to students in Yaoundé University Hospital and Medical School. Eight hundred and fifty questionnaires were distributed, 401 collected. Data were analyzed with SPSS version 16.0. Chi-square tests were used and P-values Results Mean age of respondents was 38 years (range 20-71 years. Most participants were aware that cervical cancer is a major public health concern (86%, were able to identify the most important etiological factors (58% and believed that screening may prevent cervical cancer (90% and may be performed by Pap test (84%. However, less than half considered VIA or HPV tests screening tests (38 and 47%, respectively. Knowledge about cancer etiology and screening was lowest among nurse/midwives. Conclusion Knowledge of cervical cancer and prevention by screening showed several gaps and important misconceptions regarding screening methods. Creating awareness among healthcare workers on risk factors and current methods for cervical cancer screening is a necessary step towards implementing effective prevention programs.

    Full Text Available Background: The sentinel lymph node (SLN is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. If the SLN is negative for metastatic disease, then other nodes are expected to be disease-free. SLN techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. This study aims to evaluate our technique in SLN mapping in early stage endometrial and cervical cancers. Materials and Methods: We scheduled a cross-sectional pilot study for patients undergoing staging surgery for endometrial and cervical cancer from November 2012 to February 2014 in Beheshti and Sadoughi Hospitals. Our SLN mapping technique included 1 h preoperative or intraoperative injection of 4 ml of 1% methylene blue dye in the tumor site. At the time of surgery, blue lymph nodes were removed and labeled as SLNs. Then systematic lymph node dissection was completed, and all of the nodes were sent for pathologic examination concerning metastatic involvement. All of the sentinel nodes were first stained with hematoxylin and eosin and examined. Those negative in this study were then stained with immunohistochemistry using anti-keratin antibody. Descriptive statistics, sensitivity, negative predictive values (NPV, false negative (FN and detection rates were calculated. Results: Twenty-three patients including 62% endometrial and 38% cervical cancers enrolled in the study. Median of SLN count in the endometrial and cervical cancers was 3 and 2, respectively. Among endometrial and cervical cancers, detection rate of metastatic disease was 80% and 87.5%, respectively. The FN rate for this technique was 0 and the sensitivity and NPV are 100% for both endometrial and cervical cancers. Conclusion: Considering the lower risk of metastases in early stage of both endometrial and cervical cancers, SLN technique allows for confident and accurate staging of cancer.

  15. EXPRESSION OF INTRON 9 IN CD44 GENE IN CERVICAL CANCER AND CIN AND ITS CLINICAL SIGNIFICANCE

    2006-01-01

    Objective: To detect the retention of intron 9 in CD44 mRNA in cervical cancer tissue, CIN, cervicitis and their exfoliated cells, and to study their clinical significance in diagnosis and treatment of early-stage, non-invasive cervical cancer. Methods: RT-PCR methods were used to detect the retention of intron 9 in CD44 mRNA in 30 cases of cervical cancer tissue, 11 cases of CIN tissue, 30 cases of cervicitis tissue and their exfoliated cells. Results: The retention rate of intron 9 in CD44 gene transcripts were 76.7% in cervical cancer tissue, 89.8% in corresponding exfoliated cells, 70.8% in CIN tissue, and 60.0% in CIN exfoliated cells, but undetected in neither cervicitis tissue nor exfoliated cells. The relative quantity of intron 9 in CD44 gene transcripts was 1.10 ( 0.12 in cervical cancer tissue, 1.21 ( 0.11 in CIN tissue, 1.11 ( 0.19 in cervical cancer exfoliated cells, 1.17 ( 0.12 in CIN exfoliated cells respectively, but undetected in neither cervicitis tissue nor exfoliated cells. The retention rate and relative content of intron 9 in CD44 gene transcripts in cervical cancer and CIN tissue and their exfoliated cells were statistically higher than that in cervicitis and their exfoliated cells (P0.05). Conclusion: Detecting the retention of intron 9 in CD44 mRNA in cervical exfoliated cells was more sensitivity than traditional cytology exam for diagnosing cervical cancer, and the techniques was worth clinical application.

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

    Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma. PMID:26550522

    Ying Liu; Liang-Zhi Xu

    2012-01-01

    Objective:To investigate association between glutathione S-transferases (GSTs) and cervical cancer.Methods:Published literature from PubMed, EMBASE, and other databases were retrieved. All studies evaluating the association betweenGSTM1/GSTT1 polymorphisms and cervical were included. Pooled odds ratio (OR) and95% confidence interval (CI) were calculated using fixed- or random-effects model.Results:A total of15 case-control studies were included in the meta-analysis of GSTM1 genotypes (1 825 cases and2 104 controls). The overall result showed that the association betweenGSTM1 null genotype and risk for cervical cancer was statistically significant (OR=1.53, 95%CI=1.18-2.00). Great heterogeneity was found between studies. Subgroup analysises were performed based on smoking and ethnicity. Our results showed that smokers with nullGSTM1 genotype had higher risk of cervical cancer (OR=1.56,95%CI=1.01-2.41). For the ethnicity stratification, significant increased risk of nullGSTM1 genotype was found in Chinese and Indian population, but no increased risk in other population.Conclusions:This meta-analysis provides strong evidence that theGSTM1 null genotype is associated with the development of cervical cancer, and especially in Chinese and Indian population, and smoking shows a modification on the association between GSTM1 null genotype and cervical cancer.

  1. Cervical cancer screening: on the way to a shift from cytology to full molecular screening.

    Dijkstra, M G; Snijders, P J F; Arbyn, M; Rijkaart, D C; Berkhof, J; Meijer, C J L M

    2014-05-01

    Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed by cytology. Consequently, there is a need for a better screening test. The insight that infection with high-risk human papillomavirus (hrHPV) is the causal agent of cervical cancer and its precursors has led to the development of molecular tests for the detection of hrHPV. Strong evidence now supports the use of hrHPV testing in the prevention of cervical cancer. In this review, we will discuss the arguments in favor of, and concerns on aspects of implementation of hrHPV testing in primary cervical cancer screening, such as the age to start hrHPV-based screening, ways to increase screening attendance, requirements for candidate hrHPV tests to be used, and triage algorithms for screen-positive women.

  2. Assessment of Absorbed Dose in Persons close to the Patients during 192Ir brachytherapy for Cervical Cancer

    According to the 2007 Annual Report of the National Cancer Registry, cervical cancer showed an occurring frequency of 7th in female cancers and 4rd in females with an age of 35-64 years. Both radiotherapy and chemotherapy are mainly used for the treatment of cervical cancer. In case of radiotherapy, brachytherapy using radioisotopes in conjunction with external-beam radiation therapy (EBRT) using a linear accelerator is used in most cases to improve the outcome of cancer treatment. Brachytherapy, one of the cervical cancer radiotherapies, is a method that can minimize the damage of normal tissues restricting absorbed dose to uterus. It is, however, necessary to conduct a quantitative assessment on brachytherapy because it may cause radiation exposure to medical care providers during the radiotherapy. Therefore, the study provides the basic research data regarding brachytherapy for cervical cancer, estimating the absorbed dose in persons close to the patients using a mathematical phantom during 192Ir brachytherapy for cervical cancer

  3. Screening for cervical cancer: new alternatives and research

    Lörincz Attila T

    2003-01-01

    Full Text Available Evidence for the clinical utility of human papillomavirus (HPV DNA testing has increased over the years and has now become very convincing. Some specific uses of HPV detection are a triage of women with cytological determinations of atypical squamous cells of undetermined significance (ASC-US and related management strategies, b as a marker for test of cure post-treatment, and c most importantly, as an adjunct to cytology in routine cervical disease screening programs. There are many studies that support each of these applications and include 8 studies on ASC-US triage, 10 on test of cure and 13 on adjunctive or stand-alone HPV screening. The most notable investigation of ASC-US triage was ALTS, a randomized controlled trial of 3 488 women. With respect to routine HPV screening the combined studies included 77 000 women, providing as a histological endpoint more than 1 000 cases of high-grade cervical intraepithelial neoplasia (CIN or cancer. Testing methods were either the Hybrid Capture 2 (HC2 test or the polymerase chain reaction (PCR test. HPV testing of women with ASC-US cytology had on average a higher sensitivity (90% and specificity (70% than repeating the cytological test (sensitivity 75%, specificity 60% and was also more sensitive than colposcopy for follow-up. As an adjunct to the Papanicolaou (Pap cytology test in routine screening, HPV DNA testing was a more sensitive indicator for prevalent high-grade CIN than either conventional or liquid cytology. A combination of HPV DNA and Papanicolaou testing had almost 100% sensitivity and negative predictive value. The specificity of the combined tests was slightly lower than the specificity of the Papanicolaou test. One "double-negative" HPV DNA and Papanicolaou test indicated a higher prognostic assurance against risk of future CIN 3 than three subsequent negative conventional Papanicolaou tests and may safely allow three-year or longer screening intervals for such low- risk women.

  4. Tumor hypoxia, p53, and prognosis in cervical cancers

    Background: The p53 protein is involved in the regulation of initiation of apoptosis. In vitro, p53-deficient cells do not respond to hypoxia with apoptosis as do p53-normal cells, and this may lead to a relative growth advantage of cells without a functioning p53 under hypoxia. On the basis of this hypothesis, a selection of cells with a functionally inactive p53 may occur in hypoxic tumors. The development of uterine cervical carcinomas is closely associated with infections of human papilloma viruses, which may cause a degradation of the tumor suppressor gene p53, resulting in a restriction of apoptosis. Thus, cervical cancers have often a functionally inactive p53. The purpose of our clinical study was therefore to investigate the association between p53, hypoxia, and prognosis in cervical cancers in which the oxygenation status can be determined by clinical methods. Material and Methods: Seventy patients with locally advanced squamous cell cervical cancer Stages IIB (n=14), IIIB (n=49), and IVA (n=7) were investigated in the period from 1996 through 1999. All were treated with definitive radiotherapy with curative intent by a combination of external radiotherapy plus high-dose-rate afterloading. Before therapy, tumor oxygenation was measured with a needle probe polarographically using the Eppendorf histograph. Hypoxic tumors were defined as those with pO2 measurements below 5 mm Hg (HF5). Pretreatment biopsies were taken and analyzed immunohistologically for p53 protein expression with the DO-7 antibody. The DNA index was measured by flow cytometry. The statistical data analysis was done with SPSS 9.0 for Windows. Results: The 3-year overall survival was 55% for the whole group of patients. Clinical prognostic factors in a multivariate analysis were pretreatment hemoglobin level (3-year survival 62% for patients with a pretreatment hemoglobin ≥11 g/dl vs. 27% for hemoglobin <11 g/dl, p=0.006) and FIGO stage (Stage IIB: 65%; Stage IIIB: 60%; Stage IVA: 29%, p

    Full Text Available Abstract Background Mitochondrial DNA (mtDNA is known for high mutation rates caused by lack of protective histones, inefficient DNA repair systems, and continuous exposure to mutagenic effects of oxygen radicals. Alterations in the non-coding displacement (D loop of mitochondrial DNA are present in many cancers. It has been suggested that the extent of mitochondrial DNA mutations might be useful in the prognosis of cancer outcome and/or the response to certain therapies. In order to investigate whether a high incidence of mutations exist in mitochondrial DNA of cervical cancer patients, we examined the frequency of mutations in the D-loop region in 19 patients of cervical cancer. Results Mutations, often multiple, were detected in 18 of 19 (95% patients. The presence of mutations correlated with Human Papilloma Virus (HPV infection in these patients. Mutations were also detected in normal samples and lymphocytes obtained from cervical cancer patients, but their frequency of occurrence was much lower as compared to the cervical cancer tissues. Conclusion Our findings indicate that D-loop alterations are frequent in cervical cancers and are possibly caused by HPV infection. There was no association of mtDNA D-loop mutations with the histopathological grade and tumor staging.

    Long noncoding RNA PVT1 has been reported to be dysregulated and play vital roles in a variety of cancers. However, the functions and molecular mechanisms of PVT1 in cervical cancer remain unclear. The objective of this study was to investigate the expression, clinical significance, biological roles, and underlying functional mechanisms of PVT1 in cervical cancer. Our results revealed that PVT1 is upregulated in cervical cancer tissues. Enhanced expression of PVT1 is associated with larger tumor size, advanced International Federation of Gynecology and Obstetrics stage, and poor prognosis of cervical cancer patients. Using gain-of-function and loss-of-function approaches, we demonstrated that overexpression of PVT1 promotes cervical cancer cells proliferation, cell cycle progression and migration, and depletion of PVT1 inhibits cervical cancer cell proliferation, cell cycle progression, and migration. Mechanistically, we verified that PVT1 binds to EZH2, recruits EZH2 to the miR-200b promoter, increases histone H3K27 trimethylation level on the miR-200b promoter, and inhibits miR-200b expression. Furthermore, the effects of PVT1 on cervical cell proliferation and migration depend upon silencing of miR-200b. Taken together, our findings confirmed that PVT1 functions as an oncogene in cervical cancer and indicated that PVT1 is not only an important prognostic marker, but also a potential therapy target for cervical cancer.

    Full Text Available HPV is closely associated with cervical cancer that the incidence of this tumor is regarded as a surrogate marker for HPV infection in countries lacking epidemiological studies. HPV is also implicated in subsets of anogenital and oro-pharyngeal cancers. Although cervical cancer is the third most common cancer in women worldwide, its reported incidence is low in Saudi Arabia, ranking number 12 between all cancers in females and accounts only for 2.4% of all new cases, despite the lack of national screening programs. However, the limited available studies from Saudi Arabia indicate that HPV prevalence and genotypes’ distribution in invasive cervical cancer show similar pattern as in the world. Cytology screening (Pap Smear and HPV vaccinations are the two preventive measures against cervical cancer. The two available vaccines are effective against the two most common HPV genotypes (HPV-16 and 18. Since 92% of cervical tumors in the Kingdom are infected with HPV of which 78% are HPV-16 and 18 genotypes, vaccination is expected to protect against more than two-third of cervical cancers in Saudi Arabia. Nevertheless, due to its low incidence (2.1/100,000 women, a proper cost-effectiveness analysis is required to justify the implementation of a costly vaccine bearing in mind that HPV could potentially be associated with about 3% of all cancers. However, further studies are needed to ascertain the real prevalence of HPV at the population level at large, its association with various types of cancers and also the impact of local tradition and emerging behavioral trends that could affect HPV transmission and consequently the effectiveness of applying national vaccination program.

    Highlights: • As{sub 2}O{sub 3} inhibits growth of cervical cancer cells and expression of HPV oncogenes in these cells. • HPV-negative cervical cancer cells are more sensitive to As{sub 2}O{sub 3} than HPV-positive cervical cancer cells. • HPV-18 positive cervical cancer cells are more sensitive to As{sub 2}O{sub 3} than HPV-16 positive cancer cells. • Down-regulation of HPV oncogenes by As{sub 2}O{sub 3} is partially due to the diminished AP-1 binding. - Abstract: Arsenic trioxide (As{sub 2}O{sub 3}) has shown therapeutic effects in some leukemias and solid cancers. However, the molecular mechanisms of its anticancer efficacy have not been clearly elucidated, particularly in solid cancers. Our previous data showed that As{sub 2}O{sub 3} induced apoptosis of human papillomavirus (HPV) 16 DNA-immortalized human cervical epithelial cells and cervical cancer cells and inhibited the expression of HPV oncogenes in these cells. In the present study, we systemically examined the effects of As{sub 2}O{sub 3} on five human cervical cancer cell lines and explored the possible molecular mechanisms. MTT assay showed that HPV-negative C33A cells were more sensitive to growth inhibition induced by As{sub 2}O{sub 3} than HPV-positive cervical cancer cells, and HPV 18-positive HeLa and C4-I cells were more sensitive to As{sub 2}O{sub 3} than HPV 16-positive CaSki and SiHa cells. After As{sub 2}O{sub 3} treatment, both mRNA and protein levels of HPV E6 and E7 obviously decreased in all HPV positive cell lines. In contrast, p53 and Rb protein levels increased in all tested cell lines. Transcription factor AP-1 protein expression decreased significantly in HeLa, CaSki and C33A cells with ELISA method. These results suggest that As{sub 2}O{sub 3} is a potential anticancer drug for cervical cancer.

  12. Association of p21 SNPs and risk of cervical cancer among Chinese women

    The p21 codon 31 single nucleotide polymorphism (SNP), rs1801270, has been linked to cervical cancer but with controversial results. The aims of this study were to investigate the role of p21 SNP-rs1801270 and other untested p21 SNPs in the risk of cervical cancer in a Chinese population. We genotyped five p21 SNPs (rs762623, rs2395655, rs1801270, rs3176352, and rs1059234) using peripheral blood DNA from 393 cervical cancer patients and 434 controls. The frequency of the rs1801270 A allele in patients (0.421) was significantly lower than that in controls (0.494, p = 0.003). The frequency of the rs3176352 C allele in cases (0.319) was significantly lower than that in controls (0.417, p < 0.001).The allele frequency of other three p21 SNPs showed not statistically significantly different between patients and controls. The rs1801270 AA genotype was associated with a decreased risk for the development of cervical cancer (OR = 0.583, 95%CI: 0.399 - 0.853, P = 0.005). We observed that the three p21 SNPs (rs1801270, rs3176352, and rs1059234) was in linkage disequilibrium (LD) and thus haplotype analysis was performed. The AGT haplotype (which includes the rs1801270A allele) was the most frequent haplotype among all subjects, and both homozygosity and heterozygosity for the AGT haplotype provided a protective effect from development of cervical cancer. We show an association between the p21 SNP rs1801270A allele and a decreased risk for cervical cancer in a population of Chinese women. The AGT haplotype formed by three p21 SNPs in LD (rs1801270, rs3176352 and rs1059234) also provided a protective effect in development of cervical cancer in this population

  13. Identification of biomarkers for cervical cancer in peripheral blood lymphocytes using oligonucleotide microarrays

    SHENG Jie; ZHANG Wei-yuan

    2010-01-01

    Background Oligonucleotide microarrays are increasingly being used to identify gene expression profiles that associated with complex genetic diseases. Peripheral lymphocytes communicate with cells and extracellular matrixes in almost all tissues and organs in human body, suggesting that the gene expression profiles in peripheral lymphocytes may reflect the presence of disease in the body. This study aimed to identify molecular biomarkers for cervical cancer in peripheral blood lymphocytes by using oligonucleotide microarrays.Methods Total RNA was extracted from peripheral blood lymphocytes of 24 early stage cervical cancer patients and 18 healthy controls. We used 22K Human Genome microarrays to profile peripheral blood lymphocytes from 4 early stage cervical cancer patients and compared their gene expression profiles with those from 3 healthy controls. Differentially expressed genes would be identified if they had adjusted P values of less than 0.05 and a groupwise average fold change greater than 1.5 or less than 0.67. Then the selected 5 genes were validated in the remaining 20 early stage cervical cancer patients and the 15 healthy controls by using real-time reverse-transcription polymerase chain reaction (RT-PCR).Results Genes identified by the gene selection program expressed differently between the blood samples of the early stage cervical cancer patients and those of the healthy controls. To validate the gene expression data, 5 genes were analyzed by real-time RT-PCR. In three of the 5 identified genes, tenasin-c (TNC), nuceolin (NCL), and enolase 2 (ENO2) showed a significant up-regulation in the blood samples of the early stage cervical cancer patients versus that of the healthy controls.Conclusions The up-regulation of TNC, NCL, and ENO2 in peripheral blood may be used to identify novel blood biomarkers for detecting cervical cancer in a clinically accessible surrogate tissue, and thus to provide a possibility to develop a noninvasive and predictive

  14. New strategies in advanced cervical cancer: from angiogenesis blockade to immunotherapy.

    Tewari, Krishnansu S; Monk, Bradley J

    2014-11-01

    Cervical cancer remains unique among solid tumor malignancies. Persistent infection with oncogenic subtypes of the human papillomavirus (HPV) results in carcinogenesis, predominantly occurring at the cervical transformation zone where endocervical columnar cells undergo metaplasia to a stratified squamous epithelium. The molecular cascade involving viral oncoproteins, E6 and E7 and their degradative interactions with cellular tumor suppressor gene products, p53 and pRb, respectively, has been precisely delineated. The precursor state of cervical neoplasia may last for years allowing for ready detection through successful screening programs in developed countries using cervical cytology and/or high-risk HPV DNA testing. Prophylactic HPV L1 capsid protein vaccines using virus-like-particle technology have been developed to prevent primary infection by the most common high-risk HPVs (16 and 18). Women who lack access to health care and those who undergo sporadic screening remain at risk. Although radical surgery (including fertility-sparing surgery) is available for patients with early-stage cancers, and chemoradiation plus high-dose-rate brachytherapy can cure the majority of those with locally advanced disease, patients with metastatic and nonoperable recurrent cervical cancer constitute a high-risk population with an unmet clinical need. On August 14, 2014, the FDA approved the antiangiogenesis drug bevacizumab for women with advanced cervical cancer. This review will highlight advances in translational science, antiangiogenesis therapy and immunotherapy for advanced disease. PMID:25104084

    2016-01-01

    Objective:To study the expression of FoxM1 and downstream related target molecules in cervical cancer tissue.Methods:Cervical cancer tissue and normal cervical tissue were collected to detect the expression of FoxM1, proliferation-related genes (CDK6 and CDK8) and angiogenesis-related genes (VEGFA, VEGFB and VEGFC); Hela cells were cultured and transfected with FoxM1 siRNA, and then expression of CDK6, CDK8, VEGFA, VEGFB and VEGFC were detected.Results:mRNA contents of FoxM1, CDK6, CDK8, VEGFA, VEGFB and VEGFC in cervical cancer tissue were significantly higher than those in normal cervical tissue; mRNA content of FoxM1 was positively correlated with mRNA contents of CDK6, CDK8, VEGFA, VEGFB and VEGFC; mRNA contents of CDK6, CDK8, VEGFA, VEGFB and VEGFC of FoxM1-siRNA group were significantly lower than those of negative control-siRNA group.Conclusion:FoxM1 expression abnormally increases in cervical cancer tissue, and its downstream target genes include CDK6, CDK8, VEGFA, VEGFB and VEGFC.

  16. Breast and cervical cancer screening in Great Britain: Dynamic interrelated processes.

    Labeit, Alexander; Peinemann, Frank

    2015-12-01

    No previous analysis has investigated the determinants of screening uptake for breast and cervical cancer screening for possible spillover effects from one type of screening examination to the other type of screening examination with a dynamic bivariate panel probit model. For our analysis, we used a dynamic random effects bivariate panel probit model with initial conditions (Wooldridge-type estimator) and dependent variables were the participation of breast and cervical cancer screening in the recent year. The balanced panel sample consisted of 844 women from the British Household Panel Survey (BHPS) from the time period 1992 to 2008. Our analysis showed the high relevance of past screening behaviour and the importance of state dependency for the same and the other type of cancer screening examinations even after controlling for covariates and unobserved heterogeneity. The uptake for breast and cervical cancer screening was higher when the same screening examination was done one or three years earlier. This result is in accordance with the medical screening programmes in Great Britain. With regard to breast and cervical cancer screening positive spillover effects existed between screening examinations in the third order lags. Women with a previous visit to a general practitioner and individuals in the recommended age groups had a higher uptake for breast and cervical cancer screening. Other socioeconomic and health related variables had non-uniform results in both screening examinations. Promoting the uptake of one female prevention activity could also enhance the uptake of the other prevention activity. PMID:26487452

    Full Text Available Cervical cancer is a major public health problem in Latin America, and in much of the underdeveloped world. This issue has not historically been addressed as a health priority, but in recent years is receiving increased attention and funding. This ethnographic study on the experience of cervical cancer was conducted in Iquitos, Peru, between August 1998 and May 1999. Research methodologies included: (1 observation and household interviews to obtain background knowledge about the region, medical systems, and local cultural understanding of illness; (2 cancer experience interviews; and (3 case studies of women in various stages of cervical cancer or diagnosis. Findings are presented related to local knowledge and experience of Pap smears and cervical cancer and the ineffectiveness of a recently initiated cervical cancer screening program. The findings guide recommendations for interventions in the region in relation to: (1 needed changes in health education, (2 screening frequency and age, (3 sites for screening and treatment, (4 type and availability of treatment, (5 payment issues, (6 documentation of care, and (7 the potential of herbal remedies.

  18. Are radon gas measurements adequate for epidemiological studies and case control studies of radon-induced lung cancer?

    The lung dose derived from radon is not attributed to the radon gas itself, but instead to its short-lived progeny. However, in many epidemiological studies as well as in case control studies of the radon risk, the excess number of cancers are related to the radon gas exposure, and not to the radon progeny exposure. A justification for such an approach has resorted to the assumption that there is self-compensation between the radiation doses from the unattached and attached fractions. In the present study, we used the Jacobi model to calculate the radon progeny concentrations in a room by varying the attachment rate and then calculated the resulting lung dose. It was found that self-compensation was not fully realised, and the effective dose can vary by a factor up to ∼2 for the same radon gas concentration. In conclusion, the radon gas concentration alone does not provide adequate information on the effective dose. (authors)

  19. Sociodemographic gradients in breast and cervical cancer screening in Korea: the Korean National Cancer Screening Survey (KNCSS 2005-2009

    2011-06-01

    Full Text Available Abstract Background Cancer screening rates in Korea for five cancer types have increased steadily since 2002. With regard to the life-time cancer screening rates in 2009 according to cancer sites, the second highest was breast cancer (78.1% and the third highest was cervical cancer (76.1%. Despite overall increases in the screening rate, disparities in breast and cervical cancer screening, based on sociodemographic characteristics, still exist. Methods Data from 4,139 women aged 40 to74 years from the 2005 to 2009 Korea National Cancer Screening Survey were used to analyze the relationship between sociodemographic characteristics and receiving mammograms and Pap smears. The main outcome measures were ever having had a mammogram and ever having had a Pap smear. Using these items of information, we classified women into those who had had both types of screening, only one screening type, and neither screening type. We used logistic regression to investigate relationships between screening history and sociodemographic characteristics of the women. Results Being married, having a higher education, a rural residence, and private health insurance were significantly associated with higher rates of breast and cervical cancer screening after adjusting for age and sociodemographic factors. Household income was not significantly associated with mammograms or Pap smears after adjusting for age and sociodemographic factors. Conclusions Disparities in breast and cervical cancer screening associated with low sociodemographic status persist in Korea.

  2. Efficacy of concurrent chemoradiotherapy in cases with cervical lymph node metastasis from oropharyngeal or hypopharyngeal cancer

    We reported the efficacy of concurrent chemoradiotherapy(CCRT) for cervical lymph node metastasis in patients with oropharyngeal or hypopharyngeal squamous cell carcinoma. The subjects were 17 patients with oropharyngeal or hypopharyngeal cancer with cervical lymph node metastasis, who underwent CCRT treatment between January 2005 and December 2009. The proportion of patients showing a complete response (CR) was 64.7%; however, if patients without any residual viable cancer cells in the specimens obtained by neck dissection were also defined as CR, then, 82.4% achieved CR. Thus, CCRT showed good efficacy without the need for planned neck dissection (PND). The limited recurrence cases and absence of serious complications associated with neck dissection after CCRT suggested that PND is not necessarily required. However, since assessment of cervical lymph nodes after CCRT is difficult, it would be desirable to develop a reliable examination and to study the most suitable examination for detecting the presence/absence of cervical lymph node metastasis.

    Full Text Available It is estimated that Haiti has the highest incidence of cervical cancer in the Western Hemisphere. There are currently no sustainable and affordable cervical cancer screening programs in Haiti. The current status of screening services and knowledge of health care professionals was assessed through a Knowledge, Attitudes, and Practices survey on cervical cancer screening and prevention. It was distributed to Project Medishare for Haiti health care workers (n = 27 in the Central Plateau. The majority (22/27 of participants stated pre-cancerous cells could be detected through screening, however, only four had ever performed a pap smear. All of the participants felt a screening program should be started in their area. Our data establishes that knowledge is fairly lacking among healthcare workers and there is an opportunity to train them in simple, cost effective “screen-and-treat” programs that could have a great impact on the overall health of the population.

  6. Can We Be Less Radical with Surgery for Early Cervical Cancer?

    Macdonald, Madeleine C; Tidy, John A

    2016-03-01

    Although a rare cancer in the developed world due to the success of cervical screening programmes, cervical cancer remains one of the most common cancers diagnosed in women under the age of 35 years old. Radical hysterectomy and more recently radical trachelectomy have been highly effective in curing the majority of women with early stage disease. Many, however, are left with long-term 'survivorship' issues including bowel, bladder and sexual dysfunction. In view of these chronic co-morbidities, many clinicians now consider whether a less radical approach to surgery may be an option for some women. This review focuses on the current evidence for the safety of conservative surgery for early stage cervical cancer with regard to cure rates in comparison to standard management, as well as any improvement in short and long-term morbidity associated with a more conservative approach.

    2009-02-01

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

  9. Diffusion Weighted MRI as a predictive tool for effect of radiotherapy in locally advanced cervical cancer

    Haack, Søren; Tanderup, Kari; Fokdal, Lars;

    Diffusion weighted MRI has shown great potential in diagnostic cancer imaging and may also have value for monitoring tumor response during radiotherapy. Patients with advanced cervical cancer are treated with external beam radiotherapy followed by brachytherapy. This study evaluates the value of DW......-MRI for predicting outcome of patients with advanced cervical cancer at time of brachytherapy. Volume of hyper-intensity on highly diffusion sensitive images and resulting ADC value for treatment responders and non-responders is compared. The change of ADC and volume of hyper-intensity over time of BT is also...

    Young age at first sexual intercourse (AFI) is an important risk factor for cervical cancer, but no simple statistical model of its influence has been established. We investigated the relationship between risk of cervical carcinoma and time since first intercourse using data on monogamous women (5...... proportional to the square of time since first intercourse (exponent 1.95, 95% CI: 1.76-2.15) up to age 45. First cervical infection with human papillomavirus (HPV) often occurs soon after first sexual intercourse, so early AFI is a reasonable proxy for early age at first exposure to HPV. In addition, age...

    ABSTRACT Metastasis to the uterine cervix is a complication of breast cancer that is not commonly known. Detection of cervical metastasis before the diagnosis of the primary tumor is even rarer. The present report describes a case of a 52-year-old woman who had a large cervical tumor appearing as a leiomyoma. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. Histopathological examination of the cervical tumor showed patterns characteristic of invasive lobular carcinoma of the breast, leading to the discovery of the primary in the left breast. She subsequently underwent mastectomy, hormone therapy and chemotherapy, and is alive at 7-year follow-up. PMID:23092107

    Treatment of advanced and relapsed cervical cancer is frequently ineffective, due in large part to chemoresistance. To examine the pathways responsible, we employed the cervical carcinoma-derived SiHa and CaSki cells as cellular models of resistance and sensitivity, respectively, to treatment with chemotherapeutic agents, doxorubicin, and cisplatin. We compared the proteomic profiles of SiHa and CaSki cells and identified pathways with the potential to contribute to the differential response....

    Pentraxin 3 (PTX3) as an inflammatory molecule has been shown to be involved in immune response, inflammation, and cancer. However, the effects of PTX3 on the biological features of cervical cancer cells in vitro and in vivo have not been delineated. Immunohistochemical staining showed that increased PTX3 expression was significantly associated with tumor grade (P

    Full Text Available Abstract Background Screening tests for cervical cancer are effective in reducing the disease burden. In Thailand, a Pap smear program has been implemented throughout the country for 40 years. In 2008 the Ministry of Public Health (MoPH unexpectedly decided to scale up the coverage of free cervical cancer screening services, to meet an ambitious target. This study analyzes the processes and factors that drove this policy innovation in the area of cervical cancer control in Thailand. Methods In-depth interviews with key policy actors and review of relevant documents were conducted in 2009. Data analysis was guided by a framework, developed on public policy models and existing literature on scaling-up health care interventions. Results Between 2006 and 2008 international organizations and the vaccine industry advocated the introduction of Human Papillomavirus (HPV vaccine for the primary prevention of cervical cancer. Meanwhile, a local study suggested that the vaccine was considerably less cost-effective than cervical cancer screening in the Thai context. Then, from August to December 2008, the MoPH carried out a campaign to expand the coverage of its cervical cancer screening program, targeting one million women. The study reveals that several factors were influential in focusing the attention of policymakers on strengthening the screening services. These included the high burden of cervical cancer in Thailand, the launch of the HPV vaccine onto the global and domestic markets, the country’s political instability, and the dissemination of scientific evidence regarding the appropriateness of different options for cervical cancer prevention. Influenced by the country’s political crisis, the MoPH’s campaign was devised in a very short time. In the view of the responsible health officials, the campaign was not successful and indeed, did not achieve its ambitious target. Conclusion The Thai case study suggests that the political crisis was a

    Human papilloma virus (HPV) expressing E6 and E7 oncoproteins, is known to inactivate the tumor suppressor p53 through proteasomal degradation in cervical cancers. Therefore, use of small molecules for inhibition of proteasome function and induction of p53 reactivation is a promising strategy for induction of apoptosis in cervical cancer cells. The polyphenolic alkanone, 6-Gingerol (6G), present in the pungent extracts of ginger (Zingiber officinale Roscoe) has shown potent anti-tumorigenic and pro-apoptotic activities against a variety of cancers. In this study we explored the molecular mechanism of action of 6G in human cervical cancer cells in vitro and in vivo. 6G potently inhibited proliferation of the HPV positive cervical cancer cells. 6G was found to: (i) inhibit the chymotrypsin activity of proteasomes, (ii) induce reactivation of p53, (iii) increase levels of p21, (iv) induce DNA damage and G2/M cell cycle arrest, (v) alter expression levels of p53-associated apoptotic markers like, cleaved caspase-3 and PARP, and (vi) potentiate the cytotoxicity of cisplatin. 6G treatment induced significant reduction of tumor volume, tumor weight, proteasome inhibition and p53 accumulation in HeLa xenograft tumor cells in vivo. The 6G treatment was devoid of toxic effects as it did not affect body weights, hematological and osteogenic parameters. Taken together, our data underscores the therapeutic and chemosensitizing effects of 6G in the management and treatment of cervical cancer. PMID:26621832

    Little qualitative research has been conducted with cervical cancer survivors. We sought to understand the experiences of survivors in rural Eastern North Carolina and identify any barriers which may have kept women from receiving preventive Papanicolaou screenings or follow-up care. We conducted semi-structured in-depth interviews with 15 low-income and underserved cervical cancer survivors living in Eastern North Carolina. Participants included English-speaking women who attended a large cancer center for care between March 2012 and March 2013. Participants ranged from being recently diagnosed with cervical cancer to being 15 years post-diagnosis. Interviews lasted approximately 1 h and were audio-tape-recorded. On average, women were 55 years old (range 35-85) and were diagnosed with cervical cancer 3 years prior to the interview (range 0.2 to 180 months). A good proportion was uninsured or Medicaid-insured (60 %). Half reported an annual household income of less than $20,000, and 13 % reported having a college degree. The majority of survivors had limited understanding of cervical cancer, experienced persistent symptoms related to their cancer before seeking care, and were nonadherent to Papanicolaou screening recommendations. The main barriers to care reported by participants was lack of money and health insurance, followed by the perception of overall health (which equated to the belief that medical care was not needed), transportation issues, and discomfort with provider. Health professionals should focus educational efforts on the benefits of Papanicolaou screenings, the symptoms sometimes associated with cervical cancer, and the free or low-cost services available to low-income women.
