Abstract

Background: Immediate autologous tissue breast reconstruction after skin- and nipple-sparing mastectomy, is becoming increasingly popular, while the benefits are evident, the concern is in leaving breast tissue under the skin envelope, which could potentially lead to a higher chance of recurrence. We aim to determine the incidence and study the management of loco-regional recurrence (LR) of breast cancer following immediate autologous free flap reconstruction (AFFR) from a 10-year database at a single tertiary breast unit.

Methods: This is a retrospective analysis of a prospectively maintained database of consecutive patients who underwent AFFR between July 2008 and December 2018. All patients undergoing delayed reconstruction and risk-reducing surgery were excluded, leaving a total of 216 patients. Statistical analysis was performed to determine significance in the prediction of LR. Management and outcome of the LR was also studied.

Results: LR was found in 7/216 cases (3.25%). The median age at surgery for patients with LR, was 45 (range 31-54). Median time to recurrence was 54 months (7-79 months). Three patients presented with self-detected lesions. In all, 6/7 patients were ER/PR positive, 2/7 were HER2 + at recurrence, and 1/7 was triple negative. All patients underwent surgical excision for the LR followed by radiotherapy, either chemotherapy (n-5) and/or hormone therapy (n-2). No patients have developed further LR. Because of low numbers of recurrences, no statistical significance was observed for factors causing recurrence.

Conclusion: The low LR we report demonstrates that immediate AFFR is oncologically safe. Timely recognition through post-reconstruction patient education and appropriate management results in good outcomes.
