OBJECTIVE: Genetic predisposition is responsible for 5-10% of breast cancer, 10% of ovarian cancer and 2-5% of uterine cancer. The study objective was to compare genetic counseling and testing referral rates among women with breast cancer that met NCCN referral guidelines to the referral rates among women with gynecologic cancers and determine predictors of referral.
METHODS: Utilizing an institutional tumor registry database, patients from an academic women's oncology program were identified who met a subset of NCCN guidelines for genetic referral between 2004 and 2010. Patients diagnosed with ovarian cancer, breast cancer≤50years of age, or uterine cancer<50years of age were included. A retrospective electronic chart review was conducted to evaluate for a genetic referral and uptake of genetic testing.
RESULTS: 820 women were included (216 uterine, 314 breast, and 290 ovarian cancer). The overall genetic referral rate was 21.7%. 34% of eligible breast cancer patients were referred compared to 13.4% of uterine cancer and 14.5% of ovarian cancer patients (p<0.0001). Younger age, breast cancer diagnosis, family history and earlier stage were all significant referral predictors. The odds of being referred increased with the number of affected family members. 70.8% of referred patients, consulted with genetics. Among those who consulted with genetics, 95.2% underwent testing.
CONCLUSIONS: Although increasing, genetic counseling remains underutilized across cancer diagnosis. Women with breast cancer are more likely to be referred than women with gynecologic cancers. Younger age, earlier stage and positive family history appear to be predictive of referral for genetic evaluation.
