Survival comparison of breast conserving therapy and mastectomy with breast reconstruction for breast cancer using propensity score matched cohort.

ABSTRACT: Cohort studies have suggested that breast-conserving therapy (BCT) offers better survival outcomes compared to mastectomy in patients with early breast cancer (BC). However, survival comparisons between BCT and mastectomy with breast reconstruction (Mastectomy + BR) are lacking. To investigate this, we conducted a cohort study using data from the SEER database. Patients with first-diagnosed locoregional BC between 2010 and 2016 were included and categorized into BCT and Mastectomy + BR groups. Propensity score matching (PSM) was performed to reduce selection bias. Breast cancer-specific survival (BCSS) and overall survival (OS) were compared between the groups. After PSM, 56,420 patients were matched (1:1) into the BCT and Mastectomy + BR groups. No significant differences in BCSS or OS we
