Germline BRCA1/2 mutations account for approximately 15% of invasive ovarian carcinomas. Referral of all women with non‐mucinous epithelial tubo‐ovarian and peritoneal cancer, especially high‐grade serous carcinoma (HGSC) to genetic services for genetic counselling and subsequent BRCA testing, has become standard of care in many countries. Publicly funded BRCA testing was restricted to women ≤70 years old with HGSC in New Zealand for most of our study period. Referral rates of women with HGSC for BRCA mutation testing in New Zealand have not previously been reported.

To determine the proportion of eligible patients with tubo‐ovarian or peritoneal HGSC referred to Auckland Gynaecologic Oncology Centre who were referred for genetic counselling. To determine the number of patients who underwent BRCA1/2 genetic testing and the rate of germline BRCA mutations.

Eligible cases were identified from Auckland Gynaecologic Oncology multidisciplinary meetings database from 1 January 2012 to 31 December 2014. Genetic referrals sent were checked against the genetic services database to ensure that referrals were received. Genetic counselling clinic attendance, uptake and results of genetic testing were also collected.

One hundred and four eligible patients were identified with 58 patients referred. Referral rates increased from 37.5% in 2012 to 64.3% in 2014. Of the 58 patients referred, 53 attended genetic counselling, and 49 underwent BRCA mutation testing, of whom 10 (20.4%) tested positive for a germline BRCA mutation.

Overall, 55.8% of eligible patients were referred for genetic testing; however, referral rates increased with time. This BRCA mutation‐positive rate is comparable with current international data.
