Breast-Conserving Surgery or Mastectomy? : Impact on Survival

ABSTRACT: Introduction: The early randomized controlled trials revealed no differences in survival between breast-conserving surgery (BCS) and mastectomy. However, breast cancer treatment has undergone changes, and the results of recent population-based registry studies suggest superior long-term survival after BCS. To explore the current evidence, a systematic review and meta-ana lysis of population-based observational studies from 2010 and onward was conducted.

Methods:

A literature search was conducted in the PubMed, Embase, and Cochrane databases to identify relevant literature. Keywords included “mastectomy,” “breast conserving surgery,” and “survival.” The identified studies were narratively reviewed and effect sizes (hazard ratios [HRs]) for overall (OS) and breast cancer-specific su
