PURPOSE With limitations in early detection and poor treatment response, ovarian cancer is associated with significant morbidity and mortality. Up to 25% of epithelial ovarian cancer (EOC) is related to a hereditary predisposition. Current National Comprehensive Cancer Network guidelines recommend that all individuals diagnosed with EOC be offered germline genetic testing. Although this would ideally be performed by genetics professionals, a shortage of genetic counselors can affect timely access to these services. This study sought to investigate the current genetic testing practices of oncology providers to determine the feasibility of oncologist-led genetic testing for patients with EOC. METHODS A survey was distributed to members of the Society of Gynecologic Oncologists with questions regarding timing, frequency, and type of cancer genetic testing, referrals to genetics professionals, confidence with aspects of genetic testing, and any barriers to these processes. RESULTS We received 170 evaluable responses. Eighty-five percent of providers always ordered genetic testing for patients with EOC. Most providers ordered germline multigene panel testing (95.8%), generally at diagnosis (64.5%). Provider confidence with the genetic testing process was generally high and significantly differed by providers' testing practices, namely, respondents who reported always ordering genetic testing tended to be more confident in ordering testing ( P = .008), interpreting results ( P = .005), and counseling a patient ( P = .002). Patient disinterest and concerns for insurance coverage were commonly cited as barriers to testing and referrals. CONCLUSION The findings from this study suggest that oncologist-led genetic testing for patients with EOC, with referrals to genetics professionals when appropriate, has the potential to be a viable alternative service delivery model to increase access to genetic testing for patients diagnosed with EOC.
