Background: Genetic counseling is recommended for all women diagnosed with epithelial ovarian cancer, independent of family history. Despite the potential benefits to the patient and her family, referral rates remain low. We sought to assess referral rates at our institution and implement two strategies to improve both the rate of referral and the completion of counseling and testing – (1) discussion of referral for all patients reviewed at multidisciplinary treatment planning conference and (2) option of telephone counseling. Methods: Patients with a diagnosis of epithelial ovarian, fallopian tube or primary peritoneal cancer since 10/1/14 were identified through pathology reports and chart review was performed to obtain demographic data and cancer details including histology, grade and stage. Personal and family history of cancer, date of genetic counseling referral, method of genetic counseling (in-person vs. telephone), date of genetic testing and the result of genetic testing were also abstracted. Results: The rate of genetic counseling referral was 63.5% (214/337 patients). Of those referred, 61% (131/214) underwent counseling, with 77% (165/214) in person and the 23% (49/214) via telephone after initiation of the telephone counseling program in September 2017. Overall, 90% of patients who received genetic counseling underwent testing, including 92.7% of the in-person counseling cohort and 67.9% of the telephone counseling cohort to date. In total, 24.1% of patients harbored a pathogenic gene mutation, with BRCA1 mutations most common (16.5% of patients). Variants of undetermined significance were identified in 11.3% of patients. Conclusions: Telephone genetic counseling and mandatory discussion of referral at the time of treatment planning conference both appear to facilitate genetic counseling and ascertainment of actionable germline mutations. Overall, referral rates are high at our institution. The implementation of telephone-based genetic counseling programs has the potential to improve both counseling and testing rates, particularly when in-person counseling is not available or is delayed.
