The aggressive triple-negative phenotype of breast cancer (negative for estrogen and progesterone receptors and v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2 [ERBB2] [formerly human epidermal growth factor receptor 2 (HER2)]) is considered by some investigators to be a relative contraindication to breast-conserving therapy.To compare outcomes of breast-conserving therapy for patients with triple-negative breast cancer (TNBC) with those of patients with the luminal A, luminal B, and ERBB2 subtypes.Prospective database review at an academic tertiary medical center with a designated breast cancer center. We included 1851 consecutive patients ages 29 to 85 years with stages I to III invasive breast cancer who underwent breast-conserving therapy at a single institution from January 1, 2000, through May 30, 2012. Of these patients, 234 (12.6%) had TNBC; 1341 (72.4%), luminal A subtype; 212 (11.5%), luminal B subtype; and 64 (3.5%), ERBB2-enriched subtype.Breast-conserving therapy.The primary outcome measure was local recurrence (LR). Secondary outcome measures included regional recurrence, distant recurrence, and overall survival. RESULTS Triple-negative breast cancer was associated with younger age at diagnosis (56 vs 60 years; P =?.001), larger tumors (2.1 vs 1.8 cm; P
