Abstract

Patients with non-mucinous epithelial tubo-ovarian cancers should be referred for genetic testing because approximately 15% will carry an inherited mutation in the BRCA1 or BRCA2 cancer susceptibility genes. However, referral rates for genetic testing remain low. For patients who carry a BRCA mutation, failure to refer for genetic testing results in missed opportunities for therapy and prevention of future cancers in the patient and at-risk relatives. In Western Australia between July 2013 and June 2015, 40.6% of patients with non-mucinous epithelial tubo-ovarian cancers discussed at a statewide gynecologic oncology tumor board were referred for genetic testing. Our objective was to investigate the proportion of patients with non-mucinous epithelial tubo-ovarian cancers in Western Australia referred for BRCA1/2 testing from July 2015 to December 2017, following the introduction of mainstreaming and tele-counseling. A secondary aim was to compare the uptake of genetic testing between different genetic counseling modalities.
