JAMA NetworkSurvival After Breast Conservation vs Mastectomy Adjusted for Comorbidity and Socioeconomic Status

In this JAMA Surgery Original Investigation, the researchers fielded a Swedish cohort study of 48,986 women to discover whether breast conservation offers a survival benefit compared with mastectomy when results are adjusted for main confounders such as comorbidity and socioeconomic status. The main outcomes and measures were overall survival (OS) and breast cancer–specific survival (BCSS).
