This meta-analysis investigates the oncological safety of breast-conserving therapy BCT in BRCA-mutation carriers and the risk for contralateral breast cancer (CBC) compared with non-carriers, potential risk factors for ipsilateral breast recurrence (IBR) or CBC and grades these factors based on the level of evidence. A PubMed search was conducted through April 2013 to identify studies that described the risk for IBR and CBC after BCT in BRCA-mutation carriers versus non-carriers as well as studies that investigated risk factors for IBR and CBC in BRCA-mutation carriers. Results were summarized using meta-analysis when sufficient studies were available. Ten studies investigated the oncological safety of BCT in BRCA-mutation carriers versus non-carriers. There was no significant difference in IBR between carriers and controls (RR 1.45, 95 % CI 0.98-2.14). However, a significant higher risk for IBR in BRCA-mutation carriers was observed in studies with a median follow-up a parts per thousand yen7 years (RR 1.51, 95 % CI 1.15-1.98). CBCs were significantly greater in carriers versus controls (RR 3.56, 95 % CI 2.50-5.08). Use of adjuvant chemotherapy and oophorectomy were associated with a significantly lower risk for IBR in BRCA-mutation carriers. Three factors were associated with a lower risk for CBC in BRCA-mutation carriers: oophorectomy, use of tamoxifen, and age at first breast cancer. Based on current evidence, the use of BCT in BRCA-mutation carriers can be considered a reasonable option since it does not seem to increase the risk for IBR. However, several aspects should be taken into account before the final decision-making.
