Primary HPV-based Cervical Cancer Screening Algorithms in Botswana
Cervical CancerPreventionPrimary high-risk human papillomavirus (HPV) testing has become first line screening for cervical cancer in high-income countries. The feasibility of this approach in low- and middle-income countries (LMICs) is less clear, as is the role of HPV testing among women living with human immunodeficiency virus (HIV). The proposed study seeks to evaluate the accuracy of cervical cancer screening algorithms using primary HPV testing followed by various forms of visual evaluation, including visual inspection with acetic acid (VIA), colposcopy and automated visual evaluation (AVE) for the detection of high-grade cervical dysplasia, using histology as the gold standard. We will validate the AmpFire Assay for HPV self-sampling in our setting. We will determine safe screening intervals in women living with HIV (WLHIV) in an HPV-based cervical cancer screening program and compare triage strategies for positive HPV results at WHO recommended screening intervals for WLHIV. We also seek to understand in-depth the attitudes, acceptability and preferences regarding cervical cancer screening, HPV testing, and self-sampling, for women in Botswana through interviews of a sub-set of women recruited for the cervical cancer screening study. Finally, we will analyze the cost of two-stage cervical cancer screening algorithms using high-risk HPV testing in Botswana.
Early Warning Model of Susceptibility and High-risk Population of Cervical Cancer Related to HPV...
Uterine Cervical NeoplasmUterine Cervical Cancer1 moreMost uterine cervical high-risk human papillomavirus (HPV) infections are transient, with only a small fraction developing into cervical cancer. Family aggregation studies and heritability estimates suggest a significant inherited genetic component. Candidate gene studies and previous genome-wide association studies (GWASs) report associations between the HLA region and cervical cancer. Adopting a genome-wide approach, we aimed to establish an early warning model for a high-risk population of cervical cancer.
Cervical Cancer Screening With NGS-HPV Technology Based on Menstrual Blood
Cervical CancerOur study is conducted to recruit cervical cancer screening patients to evaluate the application value of using high-throughput sequencing technology to detect HPV in menstrual blood for cervical cancer screening.
Infertility Survey Among Reproductive Age Women With Gynecological and Breast Cancer
Anatomic Stage I Breast Cancer AJCC v8Anatomic Stage IA Breast Cancer AJCC v828 moreThis study develops infertility survey among reproductive age women with gynecological and breast cancer. This study aims to learn how women consider whether or not to try to have a baby after surviving cancer. The advice gathered from this survey may be shared with patients and survivors in the future, so that they have information to inform their decisions about cancer treatment and family planning.
PET/MRI Scan for the Evaluation of Resectable Stage IA1-IB3 Cervical Cancer
Stage IA Cervical CancerStage IA1 Cervical Cancer5 moreThis trial studies how well positron emission tomography/magnetic resonance imaging (PET/MRI) scan works in checking patients with stage IA1-IB3 cervical cancer that can be removed by surgery (resectable). PET/MRI scan may help doctors learn more about the spread of the disease.
Finding Barriers and Designing Solutions to Promote Women s Cancer Screening in South Africa
Cervical CancerThe primary aim of the study explore drivers of cervical cancer screening and barriers contributing to low screening coverage among women in South Africa. Secondary aims are determining preferences for cervical cancer prevention services using a discrete choice experiment and developing a multi-level package of interventions that will address barriers to cervical cancer screening and improve engagement in care among women.

Brain TumorCervical CancerPrimary Objectives To investigate the relationship between dynamic MRI, brain tumor perfusion (DSC) and permeability (DCE), and dynamic 18F-FAZA PET uptake. Secondary Objectives To investigate the relationship between tumors with greater hypoxia defined by qBOLD and 18F-FAZA PET and pathological features including proportionate necrosis, Ki-67 and IDH mutation status To investigate the correlation between the hypoxic tumor region delineated using 18F-FAZA PET and qBOLD
Testing an Implementation Science Tool to Increase Cervical Cancer Screening in Mombasa, Kenya
Cervical CancerCervical cancer is the most common cancer in women in sub-Saharan Africa, and the majority of cervical cancer mortality occur in low and middle income countries (LMICs). Many of the disparities between high and LMICs are attributed to differences in screening. Kenyan guidelines recommend screening with visual inspection methods followed by treatment of pre-cancerous lesions with cryotherapy and loop electrosurgical excision procedure (LEEP). Implementation of these are poor with only 14% of Kenyan women ever having been screened for cervical cancer as of 2014. To address this implementation gap, this application proposes three aims. In Aim 1, the investigators will describe the cervical cancer screening care cascade, from identification of female clients age 21-65 years old, through referral for follow-up of clients with positive or suspicious screens, in family planning (FP) clinics in Mombasa County. Following characterization of this cascade, an analysis will be conducted of correlates of failure to screen for cervical cancer in FP clients seen over a one-year period in Mombasa County. Aim 2 will test whether SAIA increases cervical cancer screening compared to usual procedures in a cluster randomized trial in 20 FP clinics in Mombasa County. Finally, in Aim 3, the investigators will determine the cost and budget impact of using SAIA to increase cervical cancer screening in FP clinics in Mombasa County. The results of this study have the potential to improve cervical cancer screening, and inform policy in the Mombasa DOH for a fiscally responsible evidenced-based approach for cervical cancer screening. The long-term goal is to decrease cervical cancer mortality and improve women's health.
Low-Cost Imaging for Cervical Cancer Prevention in the Texas Lower Rio Grande Valley
Malignant Neoplasms of Female Genital OrgansThe purpose of this study is to evaluate a different type of medical equipment called "High-Resolution Microendoscope" (HRME) for the diagnosis of cervical pre-cancerous lesions and cervical cancer. The investigators want to compare patients' clinical findings using the current equipment used in clinic with the clinical findings using new equipment we are testing on this research project. If the new equipment is proven to give comparable findings with current equipment being used, doctors might be able to offer a diagnosis and treat cervical lesions in one visit. It might not be necessary to wait for cervical biopsies to come back before women would receive the indicated treatment. Study subjects are being asked to participate because they have been diagnosed with an abnormal Papanicolaou (Pap) PAP smear, positive human papillomavirus (HPV) test or history of cervical dysplasia and need to have a colposcopic examination to determine the reason for abnormal results and receive treatment.
