Coherence Imaging of the Cervical Epithelium With Scanning a/LCI
Cervical DysplasiaThe purpose of this study is to develop a low coherence interferometry (LCI) endoscopic probe that can examine the cervix for evidence of cervical dysplasia. The device will make optical measurements of the cervix to determine: the difference between two different types of cervical cells: ectocervical cells and endocervical cells. Cervical dysplasia is most likely to occur at the junction between these two types of cells. features of individual cervical cells that indicate whether the cell is normal or abnormal (cervical dysplasia).
Study of the Diagnostic Efficacy of "Real Time" Niris 1300e Optical Coherence Tomography (OCT) Imaging...
Cervical Intraepithelial NeoplasiaCervix Cancer3 moreOptical Coherence Tomography (OCT) is a technology using harmless near infra-red light scatter to produce an image. Prior studies with OCT have demonstrated that OCT of the uterine cervix can differentiate between grades of pre-invasive and invasive cervical disease and cancer. This study will evaluate the ability of the NIRIS 1300e imaging (OCT) system to detect pre-invasive cervical disease and cervical cancer.
Physical Cold Atmospheric Plasma for the Treatment of Cervical Intraepithelial Neoplasia
Cervical Intraepithelial NeoplasiaCervical intraepithelial neoplasia will be treated with physical low temperature plasma in the plasma cohort compared to watchful waiting in the control cohort. Primary endpoint after 3-6 months: Pathological remission. Secondary endpoint: HPV remission.

Randomized Clinical Trial on Clinical Management of ASCUS and LSIL (ALTS)
Cervical Intraepithelial NeoplasiaApproximately 65 million Pap smears are performed each year in the United States. The vast majority of results are negative (no abnormality identified) but about 5 percent to 8 percent are reported as abnormal. Most low-grade changes regress spontaneously; only a minority of such lesions would progress to a cancer precursor without treatment. However, there is no way to determine morphologically which patients are at risk or progression. Therefore, both high- and low-grade lesions were often managed with colposcopy and directed biopsy. Epidemiologic, virologic and molecular studies have clearly demonstrated that human papillomavirus (HPV) is the central cause of cervical cancer. The motivation for the Atypical squamous cells of undetermined significance (ASCUS)- Low grade squamous intraepithelial lesion (LSIL) Triage Study (ALTS) trial was to use the information we have gained about the role of HPV to design better treatment and prevention strategies to reduce the burden of cervical cancer and its precursors. ALTS consisted of three management strategies: (1) immediate colposcopy of all women; (2) repeat cytology with colposcopy only if the results show a high grade lesion; and (3) HPV testing and repeat cytology in combination, with referral to colposcopy if either the HPV test is positive or the cytology shows a high grade lesion. Four Clinical Centers University of Alabama, Birmingham Alabama (AL); Magee-Womens Hospital, Pittsburgh Pennsylvania (PA); University of Oklahoma, Oklahoma City OK; and University of Washington, Seattle Washington (WA) enrolled approximately 5,000 women with recent diagnosis of ASCUS or LSIL. Participants were followed at six month intervals for a total of 2 years. The ALTS database and ALTS specimens continue to be a valuable research resource in studies of cervical cancer precursors, screening tests, visual assessment of the cervix and investigation of biomarkers.
Human Papillomavirus Epidemiology in Nigeria
Human Papillomavirus 18Cervical Intraepithelial Neoplasia2 moreBackground: Cervical cancer is caused by persistent infection of the lining of the cervix with some kinds of human papillomaviruses (HPV). These HPV infections are distantly related to the viruses that cause warts on the skin. Like common wart viruses, most women who have cervical infections with HPV resolve the infections within 2 years without any need for treatment. Cervical infections that do not go away may cause disease that can turn into cancer after many years. Only one study has been done in Nigeria to learn how many women have HPV infection. The results of the study differed from most other studies in the world because older women were much more likely to be infected. This study with learn whether the results found in the previous study are true in Irun also, the site of the current study. Objectives: To examine the age distribution of HPV infection and relationship to cancer of the cervix among Nigerian women. To understand how different screening methods, including HPV testing, could best reduce the risk of cervical cancer in Nigerian women. Eligibility: - Women residing in Irun, Nigeria, who are 15 years of age or older. Design: Participants complete a brief questionnaire related to demographics, household and living conditions and a longer survey with questions related to reproductive history, family history, illnesses, stressful life events and sexual history (U. of Michigan collaboration). Participants have a cervical examination, HPV test, Pap test and blood test. Women whose tests show they are infected with HPV or have cervical disease will do the following: see a doctor and have cervical biopsies of all white abnormal areas (removal of a small tissue sample from the cervix) have photographs of the cervix taken have a cervical scraping for a new kind of HPV test. Some women with normal test results are also asked to see a doctor to check the validity of the testing Women with cervical disease receive treatment by a specialist and remain in the program until treatment is successfully completed or a final diagnosis is reached. Participants may be contacted for followup up to 5 years after the final diagnosis is made.
Cervix Cytological Screening - Comparison of Tampon Self-Test and the Routine Smear.
Uterine Cervical DysplasiaUterine Cervical NeoplasmsThe purpose of this study is to compare suitability, specificity and sensitivity of the routine smear and the tampon self-test women perform at home. Study hypothesis: The tampon self-test correspond to the routine cervical smear.
Educational Video's Impact on Knowledge Regarding Cervical Cancer Screening
Human Papilloma VirusCervical DysplasiaThe researchers will be conducting a prospective randomized trial where the researchers will be introducing an educational video to see whether there is an increase in knowledge scores surrounding cervical cancer, cervical cancer screening, and prevention with HPV vaccinations.
Pilot Study In Vivo Confocal Microscopy Probe for Cervical Precancer
Precancerous ConditionCervical CancerThe goal of this proposal is to determine whether a hand-held confocal microscopy probe may perform better than standard methods in detecting cancer or pre-cancerous abnormalities of the cervix. The confocal probe will provide invivo histopathology-like images of cell morphology and three-dimensional tissue architecture non-invasively in real time.
