Evaluation of a Streamlined Oncologist-Led BRCA Mutation Testing and Counseling Model for Patients With Ovarian Cancer.

ABSTRACT: Purpose There is a growing demand for BRCA1/ 2 mutation ( BRCAm) testing in patients with ovarian cancer; however, the limited number of genetic counselors presents a potential barrier. To facilitate more widespread BRCAm testing in ovarian cancer, pretest counseling by the oncology team could shorten testing turnaround times and ease the pressure on genetic counselors. Patients and Methods The prospective, observational Evaluating a Streamlined Onco-genetic BRCA Testing and Counseling Model Among Patients With Ovarian Cancer (ENGAGE) study evaluated a streamlined, oncologist-led BRCAm testing pathway. The analysis population comprised 700 patients with ovarian cancer at 26 sites in the United States, Italy, and Spain. The primary objectives were to assess turnaround time and, using questionnaires, to evaluate stakeholder satisfaction (patients, oncologists, and geneticists or genetic counselors) with the oncologist-led BRCAm testing pathway. Results The median overall turnaround time was 9.1 weeks (range, 0.9 to 37.1 weeks), with median turnaround times in the United States, Italy, and Spain of 4.1 weeks (range, 0.9 to 37.1 weeks), 20.4 weeks (range, 2.9 to 35.4 weeks), and 12.0 weeks (range, 2.0 to 36.7 weeks), respectively. Patient satisfaction with the oncologist-led BRCAm testing pathway was high, with > 99% of patients expressing satisfaction with pre- and post- BRCAm test counseling. Oncologist satisfaction with the BRCAm testing pathway was also high, with > 80% agreeing that the process for performing BRCAm testing worked well and that counseling patients on BRCAm testing was an efficient use of their time. Oncologists expressed higher levels of satisfaction with the BRCAm testing pathway than did geneticists or genetic counselors. Conclusion The results of the ENGAGE study demonstrate that an oncologist-led BRCAm testing process is feasible in ovarian cancer. Development of local BRCAm testing guidelines similar to the one used in this study could allow faster treatment decisions and better use of resources in the management of patients with ovarian cancer.

Project description:Background. Inherited BRCA gene mutations convey a high risk for breast and ovarian cancer, but current guidelines limit BRCA mutation testing to women with early-onset cancer and relatives of mutation-positive cases. Benefits and risks of providing this information directly to consumers are unknown. Methods. To assess and quantify emotional and behavioral reactions of consumers to their 23andMe Personal Genome Service(®) report of three BRCA mutations that are common in Ashkenazi Jews, we invited all 136 BRCA1 and BRCA2 mutation-positive individuals in the 23andMe customer database who had chosen to view their BRCA reports to participate in this IRB-approved study. We also invited 160 mutation-negative customers who were matched for age, sex and ancestry. Semi-structured phone interviews were completed for 32 mutation carriers, 16 women and 16 men, and 31 non-carriers. Questions addressed personal and family history of cancer, decision and timing of viewing the BRCA report, recollection of the result, emotional responses, perception of personal cancer risk, information sharing, and actions taken or planned. Results. Eleven women and 14 men had received the unexpected result that they are carriers of a BRCA1 185delAG or 5382insC, or BRCA2 6174delT mutation. None of them reported extreme anxiety and four experienced moderate anxiety that was transitory. Remarkably, five women and six men described their response as neutral. Most carrier women sought medical advice and four underwent risk-reducing procedures after confirmatory mutation testing. Male carriers realized that their test results implied genetic risk for female relatives, and several of them felt considerably burdened by this fact. Sharing mutation information with family members led to screening of at least 30 relatives and identification of 13 additional carriers. Non-carriers did not report inappropriate actions, such as foregoing cancer screening. All but one of the 32 mutation-positive participants appreciated learning their BRCA mutation status. Conclusions. Direct access to BRCA mutation tests, considered a model for high-risk actionable genetic tests of proven clinical utility, provided clear benefits to participants. The unexpected information demonstrated a cascade effect as relatives of newly identified carriers also sought testing and more mutation carriers were identified. Given the absence of evidence for serious emotional distress or inappropriate actions in this subset of mutation-positive customers who agreed to be interviewed for this study, broader screening of Ashkenazi Jewish women for these three BRCA mutations should be considered.
