Study Design

Observational model cohort
Time perspective prospective
Arm
This is a single-arm observational study. Subjects with a history of breast cancer who have undergone BRCA1/2 testing and have received uninformative findings will enroll in this study, and then receive pre-test counseling for multiplex testing.
pre-test assessment
Subjects who consent to the study will complete a pre-test instrument that elucidates their baseline response to genetic testing (BRCA1/2) as measured by the Multidimensional Impact of Cancer Risk Assessment (MICRA), and their current cancer surveillance and prevention behaviors, as well asintentions to undergo surveillance and prevention in the next 6 months. The instrument will either be completed at the time of the counseling for multiplex testing, or by phone within approximately 7 days of sample donation.
pre test counseling
Subjects will receive appropriate pre-test counseling that will describe the range of outcomes that may results from the multiplex testing. The subject will be asked for permission to audiotape the session for later qualitative review. An outline of the pretest counseling that will be provided. In addition to a description of the genes and syndromes being tested, subjects will receive specific education regarding the following categories and subcategories of possible results a. Definitive (informative) results, b. Variants of uncertain clinical significance (VUCS), c. Uninformative negative test results, d. d. Incidental results. Then Post-counseling selection of desired information After counseling, subjects will complete an instrument indicating which genetic test results they wish to receive. They will complete this instrument in the presence of a genetic counselor, so that the subject may ask questions in order to make the choice most consistent with their preferences.
blood draw
After choosing the information they wish to receive, subjects will provide a blood sample (2 x 7 cc EDTA tubes, which will be sent to Myriad Genetics Laboratory for analysis.
post-test counseling, and post-test assessment
When results are available, subjects will be asked to return for in-person communication of the results. Results will be disclosed after confirmation of information preferences in a standard genetic counseling session.
follow-up assessments (6 and 12 months)
At 6 and 12 months post-results transmission (+/- 4 weeks), subjects will be contacted by telephone by the study RSA to complete follow-up instruments (Assessments 3 and 4; They will complete, by phone, the MICRA. They will also describe the surveillance and prevention behaviors of the preceding 6 months, and their intentions for the next 6 months. Subjects who express a high degree of distress will be offered referral to the Counseling Service, facilitated by Dr. Hay.
