Abstract | PURPOSE: METHODS: RESULTS: We enrolled 335 IBTR patients with a median follow-up of 126.6 months. No significant differences were observed in the 5-year overall survival (OS), breast cancer-specific survival (BCSS), OS after IBTR, and BCSS after IBTR and 10-year survival probability between the two groups in a multivariate analysis. After PSM, patients who had undergone repeat lumpectomy and total mastectomy (n = 90 in both groups) were included. No significant differences were observed in the 10-year OS (hazard ratio [HR] 1.08, 95% confidence interval [CI] 0.49-2.39), BCSS (HR 0.83, 95% CI 0.35-1.95), OS after IBTR (HR 0.83, 95% CI 0.38-1.83), and BCSS after IBTR (HR 0.64, 95% CI 0.28-1.47) between the two groups. CONCLUSIONS: No significant differences were observed in survival outcomes between patients with IBTR who underwent repeat lumpectomy or total mastectomy. Our results can be helpful in selecting the appropriate surgical method for IBTR.
