Among patients diagnosed with early-stage breast cancer in a large statewide cancer registry, breast-conserving therapy was associated with improved disease-specific survival compared to mastectomy; this benefit was greater among women age ≥ 50 with hormone receptor (HR)-positive disease (hazard ratio =–0.86, 95% confidence interval =–0.82-0.91) than among women age < 50 with HR-negative disease (hazard ratio =–0.88, 95% confidence interval =–0.79-0.98). These data provide confidence that breast-conserving therapy remains an effective alternative to mastectomy for early-stage disease, regardless of age or HR status.
