Increased access to genetic counseling services is of prime importance in minority and underserved populations where genetic testing is currently underutilized. Our study tested a point of care screening tool to identify high-risk low-income patients for genetic counseling in a busy county hospital oncology clinic. Eligible breast patients treated at a "safety-net" hospital, were scored into 'high-risk' (> or = 6) or 'low-risk' (< 6) groups using a screening tool on personal and family history of cancer. Genetic counseling and testing were provided at the Vanderbilt Hereditary Cancer Program (VHCP) to all 'high-risk' and some 'low-risk' participants considered to need genetic counseling by their oncologist. Ninety-nine women with a history of breast cancer were enrolled onto the study over a period of 26 months. 53.5% (53/99) had a 'high-risk' score and ethnic predominance of African-American (60.4%). Of these, 67.9% (36/53) were counseled, and 91.6% (33/36) tested with a 9% (3/33) mutation positive rate. In the 'low-risk' group, 28.2% (13/46) still met current NCCN guidelines and were referred by their oncologist. 69.2% (9/13) were counseled and tested. The 'low-risk' group of predominantly Caucasian (41.3%) participants carried a 20% (2/10) mutation positive rate; which was later adjusted to 10% to exclude a mutation not conferring a strong breast cancer risk. The screening tool was well accepted by patients; and increased access to genetic counseling. There was a subset of breast cancer affected women under 45 with no reported family history that failed to be identified. Minor alterations to the tool would enhance concordance with current NCCN guidelines.
