Key clinical point: Postmastectomy breast reconstruction (PMbR) showed breast cancer-specific survival (BCSS) outcomes comparable with those of conventional mastectomy and may be recommended in patients with stage T0-3N2-3M0 non-triple-negative breast cancer (BC).
Major finding: Compared with conventional mastectomy, PMbR did not have any significant detrimental effect on BCSS outcomes (hazard ratio [HR] 0.85; P = .197); however, histopathological grade levels III-IV (HR 3.28; P = .010), T4 stage (HR 3.08; P = .013), and triple-negative BC (HR 4.84; P < .001) were associated with worsened BCSS outcomes in the PMbR group.
Study details: This retrospective study retrieved data from the Surveillance, Epidemiology, and End Results (SEER) database and included 2545 women with N2-3M0 stage BC who underwent either PMbR (n = 761) or conventional mastectomy (n = 1784).
Disclosures: This study was supported by the Clinical Research Program of the first affiliated Hospital of Xi'an Jiaotong University, China, and other sources. The authors declared no conflicts of interest.
