[Show abstract][Hide abstract] ABSTRACT: Recent studies indicate that high-risk breast cancer patients (ie, women who carry mutations in BRCA1/2 genes) who opt for contralateral prophylactic mastectomy (CPM) have a substantially reduced risk of developing contralateral breast cancer. However, the immediate and long-term impact of this decision on women's quality of life and psychosocial functioning is largely unknown. In this study, we compared the impact of BRCA1/2 genetic test result and CPM on these outcomes among newly diagnosed breast cancer patients who opted for CPM at the time of their definitive surgical treatment versus patients who did not.
Participants were 149 high-risk women who underwent genetic counseling and testing for alterations in the BRCA1/2 genes. We measured self-reported quality of life, cancer-specific distress, and genetic testing-specific distress using standardized instruments before receipt of genetic test results and again 1 and 12 months later.
Compared with patients who chose breast conservation or unilateral mastectomy, those who chose mastectomy of the affected breast and CPM of the unaffected breast did not report diminished quality of life or elevated distress.
With respect to quality of life and distress, patients who choose CPM fare as well as those who do not in the first year after surgery.

[Show abstract][Hide abstract] ABSTRACT: Women who receive uninformative BRCA1/2 genetic test results face ongoing uncertainty about their future cancer risks. This article prospectively examined the influence of intolerance for uncertainty and perceived breast cancer risk on psychological distress following the receipt of uninformative BRCA1/2 test results. Sixty-four women who received uninformative BRCA1/2 mutation test results completed measures of Intolerance for Uncertainty, perceived breast cancer risk, and measures of cancer-related, genetic testing, and general distress. Cancer-related (DeltaR(2) = 0.18, P < or = 0.001), general (DeltaR(2) = 0.04, P < or = 0.05), and genetic testing distress (DeltaR(2) = 0.12, P < or = 0.01) were associated with intolerance for uncertainty at 1 month post-disclosure. The interaction of intolerance for uncertainty and breast cancer perceived risk predicted cancer-related (DeltaR(2) = 0.10, P < or = 0.001) and genetic testing distress (DeltaR(2) = 0.09, P < or = 0.01) at 6 months post-disclosure. Distress was highest among patients with highest perceived risk and intolerance for uncertainty, suggesting that those who have difficulty coping with their ambiguous risk are at risk for long-term distress. The clinical and research implications of these results are discussed.
