Journal of Breast Cancer Contralateral Breast Cancer and Ipsilateral Breast Tumor Recurrence in BRCA1/2 Carriers and Non-Carriers at High-Risk of Hereditary Breast Cancer 2019.09.30.J Breast Cancer. 2019 Sep 30;22(4):587-598 논문 보기PurposeWe evaluated the risk of contralateral breast cancer (CBC) and ipsilateral breast tumor recurrence (IBTR) and investigated the predictive factors for CBC and IBTR in breast cancer patients with BRCA mutations and non-carriers at high-risk of hereditary breast and ovarian cancer (HBOC).MethodsWe analyzed prospectively collected clinical data of patients with unilateral breast cancer who were at high-risk for HBOC and were tested for the BRCA mutation between 2003 and 2013.ResultsThe cohort comprised 540 patients with 45 BRCA1 carriers, 50 BRCA2 carriers, and 445 non-carriers. The median follow-up was 84.5 months. Overall, 61 patients (11.3%) developed CBC (24.4% for BRCA1 carriers, 20% for BRCA2 carriers, and 9% for non-carriers). The 10-year cumulative risk for CBC was 23.8% for BRCA1 carriers, 19.1% for BRCA2 carriers, and 9.8% for non-carriers (p = 0.174). Among the 277 patients who underwent breast-conserving surgery, 29 (10.5%) developed IBTR (9.1% for BRCA1 carriers, 16.7% for BRCA2 carriers, and 10.2% for non-carriers). The 10-year cumulative risk for IBTR for BRCA1 carriers, BRCA2 carriers, and non-carriers was 8.7%, 14.1%, and 20%, respectively (p = 0.577). BRCA1 (hazard ratio [HR], 2.94; 95% confidence interval [CI], 1.20-7.20; p = 0.019) and BRCA2 (HR, 2.88; 95% CI, 1.13-7.35; p = 0.027) mutations and negative estrogen receptor status (HR, 4.02; 95% CI, 1.60-10.08; p = 0.003) were the significant predictive factors for CBC, while tumor size ≥ 2 cm was predictive of IBTR (HR, 6.11; 95% CI, 2.03-18.33; p = 0.001).
