Diagnostic Imaging Aid for Management of Cervical Lesions
Cervical CancerCervical Intraepithelial Neoplasias2 moreA handheld digital colposcope which utilizes flurorescent light is being tested for the rapid detection and management of cervical lesions. The handheld research device captures cervical images which with the fluorescent light show the regions of cervical tissue that autofluoresce. The investigators will study the relationship between the level of fluorescence and the samples of tissue (biopsies) obtained from the patient as part of her routine care. The investigators will also compare the efficacy of the hand held device with the data being collected from the other research devices being tested by the team, i.e. the multispectral digital colposcopes.
Effectiveness of HPV Vaccine in Thai Adult Women
Uterine Cervical DysplasiaPapillomavirus VaccinesBackground: The majority of the burden of HPV-related cervical cancer is in developing countries while most of the effectiveness reports of HPV vaccination are currently coming from developed countries. Also, currently many adult women are left without either HPV vaccination or cervical cancer screening. Effectiveness data of currently available HPV vaccines among adult women in developing countries are needed for women and healthcare workers and policy makers to best protect women from cervical cancer. Primary Study Objective: - To determine the effectiveness bivalent and quadrivalent HPV vaccines in reduction of cervical dysplasia (Low-grade Squamous Intraepithelial Lesion or worse; LSIL+) attributable to HPV types 16 or 18 after at least 5 years of vaccination among Thai women vaccinated at their ages 20-45 years with at least one dose of the HPV vaccine Secondary Study Objectives: To measure the effectiveness of currently available bivalent and quadrivalent HPV vaccines in reducing the prevalence of HPV 16 or 18 To measure the effectiveness of HPV vaccines in reducing any abnormal Pap smear result (ASC-US+) To compare the effectiveness of HPV vaccines according to the number of doses immunized To find out risk factor(s) for HPV 16 or 18-related cervical dysplasia in this cohort To assess the prevalence of other high-risk HPV types in vaccinated and non-vaccinated group To determine direct and/or indirect cost of HPV vaccination The hypothesis to be tested: At least one dose of vaccination with bi- or quadri-valent HPV vaccine will reduce the prevalence of LSIL+ attributable to HPV 16/18 by 80% after at least 5 years of vaccination. Materials and Methods: This study will be a retrospective matched cohort study. Data is to be collected either by from samples for Pap and HPV test and/or HPV 16/18 genotyping of the recruited participants, or from existing medical records. HPV vaccinated women at their ages 20-45 years (vaccinated group) and women received Pap smear at their ages 20-45 years without vaccination (control group) will be included in the study. Pap smear and HPV test and/or HPV 16/18 typing result of 2 groups will be compared after ≥ 5 years of vaccination or baseline Pap smear. Those who don't have Pap smear results ≥ 5 years after vaccination or ≥ 5 years after the baseline Pap smear will be offered for a Pap smear and HPV 16/18 typing
DNA Methylation Testing for the Screening of Uterine Cervical Lesion
Cervical CancerCervical Intraepithelial Neoplasia3 moreIn our published work, host DNA methylation testing has been proved to be sensitive and specific to cervical intraepithelial neoplasia (CIN) 2 or more severe lesions (CIN2+). Its screening effects are independent of high-risk human papillomavirus (hrHPV) status. Based on the results of training and validation sets of our previous work, we perform this multicenter, prospective cohort study in unselected participants asking for cervical cancer screening in a hospital-based community. All eligible participants accept DNA methylation testing, with cytology and/or hrHPV assay. The primary endpoint is the diagnostic accuracy of DNA methylation compared with cytology and/or hrHPV status based on histology results. The accuracy analysis includes sensitivity, specificity, negative predictive value and positive predictive value.
A Comparison Study of Two Community Outreach-Based Approaches to Increase Participation of Women...
Cervical Intraepithelial NeoplasiaHuman PapillomavirusBackground: The Mississippi Delta (which includes the counties along the Mississippi River) is one of the poorest areas in the United States. Women living in the Mississippi Delta have disproportionately high rates of cervical cancer, but they are unlikely to come to clinics except perhaps for giving birth, years before they are diagnosed with cancer. To improve rates of screening, researchers are attempting an outreach study to see whether under-screened women, if approached by door-to-door recruitment, would get screened by one of two methods (home-based self-collection and testing, or a clinic exam) and which method they would prefer. Objectives: - To assess/measure increased participation of under-screened women living in the Mississippi Delta in cervical cancer screening by offering women the opportunity to get screened by one of two possible community outreach-based cervical cancer screening modalities, self-collection and HPV testing or clinic-based cytology screening, the current standard of care. Eligibility: - Women between 26 and 65 years of age, who are not pregnant currently or in the past 8 weeks, have an intact cervix, have no history of cancer, and have not been screened for cervical cancer in the past 3 years. Design: Researchers will recruit participants on a door-to-door basis. Researchers will recruit all eligible women within a household. Recruitment will be done only during daylight hours but at the end of the working day to maximize the chances of finding women at home. Eligible women willing to participate will complete a questionnaire with demographic and medical information. Participants will be asked to choose the screening method of their preference. If they choose self-collection with HPV testing, they will be given a self-collection kit and asked to perform the self-collection and return the kit within 1 month. Participants who choose to have cytology screening will be provided with the phone number and location of the local health department clinic and will be encouraged to schedule their screening within the following month. Women who do not complete their participation within 1 month will be considered noncompliant with their chosen intervention. Researchers will re-contact noncompliant women to offer them participation in the study, including permitting them to refuse to participate or to choose the alternative intervention....

Improving Cervical Cancer Screening Among HIV-Infected Women in India
Cervical CancerHIV/AIDS3 moreBackground: Cervical cancer is a major cause of cancer deaths among women. Most cases of cervical cancer are caused by the human papillomavirus (HPV). HPV is more common in women who have the human immunodeficiency virus (HIV). India has one of the highest rates of women who have both cervical cancer and HIV infection. Cervical cancer can be discovered in early stages by screening for HPV infection. Researchers want to compare new cervical cancer screening tests for HIV-infected women. They also want to know more about how HPV can lead to cervical cancer in HIV-infected women. To do so, they will hold a study to screen HIV-infected women in India. Objectives: - To improve cervical cancer screening methods in HIV-infected women in India. Eligibility: Women at least 18 years of age who have HIV infection. Participants will be recruited from HIV-focused health care clinics in Pune and Chennai, India. Design: Participants will have a physical exam and medical history. They will provide a urine sample and proof of HIV infection. Participants will have a gynecological exam. This will involve a pelvic exam and Pap smear to collect cells for study. It will also involve a cervical exam to look for precancerous cells. Cervical tissue may be collected. Participants will also provide a blood sample for testing. Participants will return in 2 weeks for the test results. If there are signs of precancerous or cancer cells, participants will be referred to a doctor for treatment.
Use of Human Papillomavirus Persistence for Determination of Treatment Efficacy Among Women With...
Human Papillomavirus InfectionCervical Intraepithelial NeoplasiaThe objectives are to evaluate the effectiveness of treatment of cervical intraepithelial neoplasia (CIN) by loop electrosurgical excision procedure using persistence of human papillomavirus (HPV) as outcome, and to perform a long-term follow-up on the ability of HPV testing, as compared to cytology, to predict recurrence of high-grade CIN.
Acceptability and Efficacy of Self-sampling for Cervical Cancer Screening: A Pilot Study
Cervical CancerCervical Dysplasia1 moreIn Singapore, the current cervical cancer screening uptake among women in Singapore has remained at low 50% since its introduction in 2004. It has been widely reported that under-screened women have the highest risk of cervical cancer. Self-sampling HPV DNA screening may be a solution to the low uptake rates of local women, particularly among the under-screened population in Singapore. Self-sampling comprises women using a swab to obtain samples from their vagina. In this study, we are comparing the sensitivity of detecting HPV positive women using HPV DNA test with self-sampling using flocked swab with the current physician sampling method. We also aim to determine acceptability of self-sampling HPV DNA test using flocked swab in cervical cancer screening. Designed as a feasibility study, it will comprise a prospective study of 300 women attending clinics in National University Hospital (NUH) and National Cancer Institute Singapore (NCIS).
HRME in the Screening of Cervical Cancer Precursor Lesions in Brazil (UH3 - Brazil)
Intraepithelial NeoplasiaIntraepithelial Neoplasm3 moreSTUDY PURPOSES: This study aims to evaluate a high resolution microendoscope (HRME): 1) To assess the sensitivity and specificity of the HRME device in the detection of cervical intraepithelial neoplasia grade 2 (CIN2) or histologically more severe lesion (NIC2+) and cervical intraepithelial neoplasia grade 3 (CIN3) or histologically more severe lesion (NIC3+) in a comprehensive case-by-case basis; 2) Compare the accuracy of the HRME device with acetic acid visualization (VIA) and colposcopy. METHODOLOGY: 1,780 women with abnormal Pap Smears (ASCUS+) or positive high-risk human papillomavirus (HPV) test in the cervix performed in the Barretos Cancer Hospital (HCB, Barretos, Brazil) screening program will be recruited, either at Mobile Prevention Units or Fixed Units, who have been referred for diagnostic investigation with colposcopy. The invitation for women to participate in the study will be made immediately before the medical consultation for colposcopy, in the Prevention Department of Barretos Cancer Hospital. Women who decide to participate in this study will sign an Informed Consent Form after invitation and relevant explanations, which will be provided by the researcher in charge or by a representative with previous training appointed by him for the application of the Form in question. During the colposcopy examination, the HRME device will be used to check the presence of precursor lesions in the cervix. HRME will capture images from all areas considered abnormal by VIA and/or colposcopy. Any abnormal areas detected by VIA and/or colposcopy will undergo a biopsy. If no abnormal area is observed, a cervical microbiopsy will be obtained from an apparently normal area examined using HRME. If during the study a precursor disease or cervical cancer is detected in any woman, an appropriate treatment will be offered by Barretos Cancer Hospital according to an institutional protocol.
