title: On using a cancer center cancer registry to identify newly affected women eligible for hereditary breast cancer syndrome testing: practical considerations.
abstract: The goals of this research were to describe the process of identifying and recruiting individuals registered with a cancer center's cancer registry who were eligible to participate in cancer genetic research. This study specifically focused on younger women with personal and family cancer histories strongly suggestive of hereditary breast cancer syndromes, as determined by genetic counselor review. Of special interest was to determine the proportion of women from minority backgrounds who were (a) identifiable in this manner and (b) interested in genetic testing for hereditary breast cancer through a family cancer clinical research program. An initial query of the 292 cases of women newly affected with breast cancer and contained within the registry indicated that 124 met demographic eligibility criteria. The personal and family cancer histories of each of these women were then reviewed by a genetic counselor and the remaining, eligible patients (n = 31) were subsequently contacted by mail and telephone: approximately three-fifths (18/31) of these patients were White and two-fifths (13/31) were Black or of another racial background. Of the women who were sent one or more study-related mailings, 10% (3/31) were unreachable by telephone due to incorrect contact information, 32% (10/31) were reachable by telephone but unresponsive to messages left, 26% (8/31) had already participated in the family cancer program (i.e., were positive controls), 6% (2/31) were interested in participating in the program, 23% (7/31) were uninterested in participating in the program, and 3% (1/31) were later determined to be ineligible. Comparing the racial backgrounds of women who were either positive controls or interested in participating (i.e., "tester" category) to women who were either unreachable, nonresponsive, uninterested, or ineligible (i.e., "nontester" category), there was a nonsignificant trend for more non-White women to fall into the nontester than tester category, Fisher's Exact Test = .09. This work underscores practical steps in planning and carrying-out cancer genetic testing research among women newly affected with breast cancer and members of special populations. It also underscores the role that genetic counseling professionals play in this process.
