Abstract

PURPOSE
The oncologic safety of immediate breast reconstruction (IBR) has been demonstrated. However, the outcome of IBR for locally advanced breast cancer (LABC) is still under debate. We compared the survival outcome of LABC patients who underwent IBR vs. mastectomy alone.
METHODS
We retrospectively analyzed a total of 248 patients with stage III breast cancer who were treated with mastectomy between 2004 and 2015. The study subjects were divided into 2 groups: patients who received IBR (n=77) or mastectomy alone (MA) (n=171). We compared disease-free survival (DFS) of both groups.
RESULTS
Median follow-up duration was 49 months and the mean age of patients was 49 years. Patients in the IBR group were significantly younger and had lower body mass index (BMI) than those in the MA group. In a univariate analysis, IBR group showed better DFS than the MA group (DFS 81.3 months vs. 49.8 months, p<0.001). There was no delay in adjuvant treatment in the IBR group. In a multivariate analysis, IBR was associated with better DFS (hazard ratio (HR) for recurrence: 0.37, 95% CI 0.20-0.69, p=0.002) when adjusted for potential prognostic factors. In a subgroup analysis performed according to disease stage (IIIA and IIIB/IIIC), DFS was significantly better in IBR than MA group in both stage subgroups (p<0.001).
CONCLUSION
We demonstrated that patients who underwent IBR showed better DFS outcome compared with patients who underwent mastectomy alone. Our results can help surgeons to determine if IBR is an option in patients with LABC.
