Patient satisfaction of BRCA1/2 genetic testing by women at high risk for breast cancer participating in a prevention trial

Abstract

With the increasing availability of cancer risk counseling and genetic testing, we need to determine the most effective way to provide complex and sensitive information to patients. This study was designed to determine the satisfaction of results delivery in women who participated in a breast cancer prevention trial and chose to undergo free and confidential BRCA1/2 genetic testing. Self-selected women at high-risk for breast cancer who were eligible to participate in a phase II chemoprevention trial, were offered free and confidential pre-test counseling and BRCA1/2 full sequencing. Subjects were not randomized but rather had the option of in person or telephone results disclosure. Those subjects with an identified germline alteration were required to follow-up with an in person consultation; this was optional for those with a negative result. A satisfaction survey was mailed to subjects after receiving their results. Ninety-seven percent (116/119) of the eligible subjects underwent genetic testing. Ninety-one percent (105/116) of those women tested responded to the follow-up survey. Twenty-four of the 26 women with an identified germline alteration responded. Nearly all of the responders were satisfied with the counseling and testing process. All of the respondents felt they made a wise decision in having the testing and would recommend that other women in a similar situation undergo genetic testing. We found that the majority of women at high risk for breast cancer participating in a prevention trial will choose to undergo anonymous and free BRCA1/2 genetic testing, be informed of the results, and are accepting of receiving results initially by phone.
