Abstract

Background: To analyze oncologic outcomes and reconstruction quality in locally advanced stage breast cancer after performing immediate autologous breast reconstruction (IABR).
Methods: From 2007 to 2014, data of patients aged ≤70 years old with stage II–III breast cancer who received total mastectomy (TM) were extracted from medical records. Exclusion criteria were: previous contralateral breast cancer, follow-up loss before adjuvant therapy completion, and artificial reconstruction. Patients were divided into two groups: (I) TM alone, and (II) TM + IABR. Overall survival (OS) and loco-regional recurrence free survival (LRRFS) were calculated. Times of minor revision, abnormal image findings in breast, and change of breast height were observed.
Results: Sixty-one of 188 patients received IABR after TM. Stage IIIB–C was the most important prognostic factor for OS (P<0.001) and LRRFS (P<0.001). For stage II, five-year TM and TM + IABR OS rates were 96.8% and 100% (P=0.324), respectively. For stage IIIB–C, five-year TM and TM + IABR OS rates were 57.6% and 62.5% (P=0.544), respectively. For stage II, five-year TM and TM + IABR LRRFS were 98.1% and 95.7% (P=0.998), respectively. For stage IIIB–C, five-year TM and TM + IABR LRRFS were 70.8% and 62.5% (P=0.378), respectively. Two major complications were observed after IABR. Minor revisions, abnormal image findings, and change of breast height were common without showing significant relation with adjuvant radiotherapy or tumor stage.
Conclusions: IABR showed feasible oncologic outcomes in 5-year follow-up. Adjuvant radiotherapy had little effect on quality of reconstruction. However, IABR in advanced stage should be cautiously applied considering expected survival and minor problems after IABR.
