Radiation Therapy Planning by Multi-parametric PET/MRI Imaging in Patients With Cervical Cancer...
Cervical CancerThe main goal of this project is to evaluate the potential and feasibility of hybrid PET/MRI functional imaging to non-invasively measure tumor characteristics for radiation therapy planning (RT) for cervical cancer. It will be assessed how the complementary information of tumor characteristics can contributed to better understanding of tumor delineation. Another endpoint of this study is to evaluate a new PET-tracer (68Ga-NODAGA- E[c(RGDyK)]2) enabling imaging of tumor-angiogenesis.
Cervical Cancer Screening in HIV Positive and Negative Women in Cambodia
Cervical NeoplasiaCervical CancerThe prevalence of cervical neoplasia in Cambodia is not known. There are no screening programs in place. The investigators plan on introducing a screening program based on WHO criteria and utilizing visualization with acetic acid. Patients who are positive will be offered same-day cryotherapy if indicated or will be referred for biopsy, LEEP and hysterectomy as indicated. The planned patient pool for this study is 1000 women, half of whom will be HIV positive (and thus have a presumed higher incidence of cervical neoplasia).
MR Metabolic Biomarkers for Cervical Cancer
Uterine Cervical NeoplasmsThe purposes of this study are: (1) to develop magnetic resonance (MR) imaging and spectroscopy as surrogate biomarkers for altered cancer metabolism in cervical cancer; (2) to understand the function of human papillomavirus (HPV) infection and autophagy (a cellular catabolic degradation response to stress) in the metabolic alterations in cervical cancer.
Prediction of Clinical Response and Outcome in Uterine Cervix Cancer
Cervix CancerObservational study based on the routine clinical treatment and diagnostic course, to correlate imaging features with outcome objectives. Outcome will evaluated as clinical response to the standard treatment and as recurrence and survival in the follow up. The study hypothesis is that data extracted form FDG-PETCT used in the routine clinical practice can predict outcomes following standard treatment.
SElf-SAMpling in Cervical Cancer Screening; SESAM Study
Cervical CancerStudy aims to support development of evidence based health care in Norway through evaluating recently proposed technological improvements in cervical cancer control before their routine use. SESAM II study evaluates the accuracy of vaginal self-sampling for high risk human papillomavirus (hrHPV) testing compared with a physician-taken sample.
Acceptability and Validity of Self Sampling for High Risk HPV Detection Among Women in Maharashtra...
Cervical CancerThe study goals are, To determine the test characteristics (sensitivity, specificity, positive predictive value, negative predictive value, false positivity rates, false negativity rates) of health personnel collected and self collected HPV samples for Hybrid capture explained by two different methods (pamphlets/ health education programme). To evaluate the agreement between self collected HPV samples and health personnel collected HPV samples for Hybrid capture with two different methods of education (pamphlets/ health education programme). To study the attitudes, acceptability and barriers of self-collection of specimens for HPV DNA testing in three sub groups of population in Maharashtra with two different methods of education (pamphlets/ health education programme). To determine the predictors of self-sampling preference. To determine the Knowledge, Attitudes and Practices (KAP) regarding cervical cancer and HPV infection among these women in pre-intervention and post-intervention period.
Cervix Image Sharing Protocol (CISP)
Cervical CancerCervical AbnormalitiesThe Clinical Epidemiology Unit in the Clinical Genetics Branch of the Division of Cancer Epidemiology, NCI has a strong interest in fostering cervical cancer prevention solutions for all kinds of settings, including lowresource ones that rely on development of robust, low-cost screening and triage tools. Therefore, to support development of algorithms for cervical image recognition software, NCI seeks to share digital cervical images and accompanying clinical data from our large epidemiological studies on HPV and cervical cancer screening with interested and qualified image analysis researchers. To accommodate the many researchers that are interested, we have created this standard protocol to describe a unified process for sharing deidentified cervical images and accompanying de-identified clinical data from the following NCI studies: Costa Rican Natural History Study of HPV and Cervical Neoplasia , ASCUS LSIL Triage Study-- ALTS , SUCCEED and Costa Rica Vaccine Trial .
Acceptability of HPV-self Sampling
Cervical CancerThis trial aimed at evaluating the acceptability of HPV self-sampling among french women eligible for cervical cancer screening (25 - 65 years old) in the region of Occitanie, in the south of France. Acceptability will be evaluated using an anonymous questionnaire and the main outcome of the study will be the response acceptability " yes " or " no " for HPV self-sampling. Secondary outcome will be analysis of socioeconomic determinants for the acceptability of HPV self-sampling. These data will help to propose new strategies for cervical cancer screening in France, particularly to taget non-attenting populations
Human Papillomavirus Infection and Virus Genotyping in Uterine Cervix Cancer in Venezuela
Cervical CancerHypothesis: If high risk genotypes of human papillomavirus (HPV) is the cause of cervical cancer worldwide, the genotypes associated with cervical cancer in Venezuela would be the same types found in other countries. Objectives: Primary objective: The objective of this investigation is to determine the presence and genotypes of HVP infection in cervical intraepithelial neoplasia grade 2/3 (CIN 2/3), and Stage I cervical epidermoid carcinoma and cervical adenocarcinoma. Specific objectives: To establish the presence of HPV in cervical cancer patients in Venezuela by geographic distribution. To establish which HPV types are linked with cervical cancer in Venezuela by geographic distribution.
Molecular Imaging for Detection of Cervical Intraepithelial Neoplasia
Cervical CancerThe hypothesis of this research project is that topical application of the anti-EGFR or anti-E6/E7 contrast agents followed by optical imaging will yield images that reflect spatial variations in expression that correlate with the presence of cervical precancer. To gather feasibility data the investigators will: Obtain cervical specimens from women with high grade squamous intraepithelial lesions (HGSILs) being treated with the loop electrosurgical excision procedure (LEEP). After Loop Electrosurgical Excision Procedure (LEEP) is performed, obtain low and high resolution optical images before and after applying contrast agents topically to the epithelial surface of the tissue for 30 minutes before rinsing. Submit the specimen for histology, and have it sectioned and stained using both H&E and immunohistochemical staining for EGFR or E6/E7. The images will be reconstructed into a two dimensional map delineating areas of Cervical Intraepithelial Neoplasia (CIN) and of EGFR or E6/E7 overexpression. Maps of the pathology will be compared to those obtained from the intact cervix exposed to the contrast agent.
