Evaluating the Effectiveness of a Telehealth Cancer Genetics Program: A BRCA Pilot Study.

Introduction: Ashkenazi Jewish (AJ) individuals face a 1 in 40 (2.5%) risk of having a BRCA mutation, which is 10 times the general population risk. JScreen launched the PEACH BRCA Study, a telehealth-based platform for BRCA education and testing, with the goal of creating an effective model for BRCA testing in low-risk AJ individuals who do not meet national testing criteria. Other goals were to determine the rate of BRCA mutations in this group, to assess the adequacy of screening for the 3 common AJ founder mutations only, and to assess satisfaction with the telehealth model to help inform a national launch of a broader cancer genetic testing program.

Methods: Criteria for participation included those who were AJ, resided in the metro-Atlanta area, were aged 25 and older, and had no personal or close family history of BRCA-related cancers. Pre-test education was provided through a video and written summary, followed by complimentary BRCA1/2 sequencing and post-test genetic counseling. Participants responded to pre- and post-test surveys, which assessed knowledge and satisfaction. Those who were not eligible to participate were sent genetic counseling resources and later surveyed.

Results: Five hundred one participants were tested and the results included 4 positives (0.8% positivity rate), 494 negatives, and 3 variants of uncertain significance. Overall satisfaction with the study process was high (96.9/100), knowledge about BRCA was high (97.5% of participants passed a pre-test knowledge quiz), and satisfaction with pre- and post-test education was high (97.9% of participants were satisfied with the pre-test video and written summary, and 99.5% felt that their post-test genetic counseling session was valuable). Many participants expressed interest in receiving broader cancer testing.

Conclusions: The BRCA founder mutation rate in a low-risk AJ population was significantly lower than the previously established AJ rate of 1 in 40. It was also determined that a telehealth model for a cancer genetics program is effective and acceptable to the population tested. This study established interest in broader cancer genetic testing through a telehealth platform and suggested that testing may be successful in the Jewish community at a national level and potentially in other populations, provided that patient education and genetic counseling are adequately incorporated.
