Polygenic Risk Scores and Multi-cancer Early Detection for Ovarian Cancer — PROMISE  

Ovarian Cancer Clinical Trial

Official title: Polygenic Risk Scores and Multi-cancer Early Detection for Ovarian Cancer

Status Enrolling by invitation

Clinical Trial Summary

The overall goal of the Polygenic Risk Scores and Multi-cancer Early Detection for Ovarian Cancer (PROMISE) study is to better understand how women may incorporate both polygenic risk score (PRS) and novel early detection strategies in their decisions regarding cancer screening and risk reducing surgery. This study will conduct qualitative interviews to better understand women's attitudes regarding polygenic risk score (PRS) and early detection assays.

Clinical Trial Description

First, the investigators will conduct qualitative interviews to better understand women's attitudes regarding polygenic risk score (PRS) and early detection assays. Participants will include English-speaking adult women with BRCA1 or BRCA2 pathogenic variants (PV) who have not previously undergone risk-reducing salpingo-oophorectomy (RRSO) (n=24). Interviews will be led by a trained member of the study team using a semi-structured interview guide in order to review definitions of test characteristics (e.g., sensitivity, specificity) and discuss participants' understanding and perceived importance of such test characteristics, and the potential impact of polygenic risk score (PRS) and early detection assay results in informing their cancer prevention decisions. Interviews will be audio-recorded utilizing Zoom audio recording and transcribed using 3Play Media transcription service (Health Insurance Portability and Accountability Act/HIPAA compliant). The investigators will lead analysis of the de-identified transcripts through a process of independent and collaborative thematic content analysis, an established method in qualitative research in order to establish key themes related to clarifying participants' willingness and concerns (e.g., discomfort with test characteristics, perceived ambiguity) for adopting these emerging tests. Findings from these qualitative interviews will also inform development of hypothetical scenarios that will then be evaluated in a subsequent questionnaire administered to 175-200 English-speaking adult women with BRCA1 or BRCA2 Pathogenic Variants who have not previously undergone risk-reducing oophorectomy or risk-reducing mastectomy. The objective of this survey will be to further evaluate women's decision-making responses to hypothetical polygenic risk score (PRS) and early detection assays, and to determine if there are test characteristics and result thresholds that appear meaningful. Details of this questionnaire and its administration will be included in a future amendment to this current protocol. Results from year 1 will be used to develop patient materials to use in providing individualized polygenic risk score (PRS) and early detection assay results back to patients in years 2-3. Taken together, investigators hope that this project will provide an estimate on the absolute magnitude of risk which would result in risk reducing surgery within a year, and how a negative early detection assay might modulate such action. ;
