Limiting complication rates in implant-based breast reconstruction.

BACKGROUND: External beam radiotherapy (XRT) to the breast has been shown to increase complication rates in women undergoing implant-based breast reconstruction (IBBR). Owing to concerns about high complication and failure rates, our department began to favour autologous reconstructive in patients requiring XRT in 2013. This study assesses the outcomes of IBBR prior to and following this policy change.

METHODS: The records of all patients who underwent first-stage IBBR in 2012 and 2013 in our department were reviewed. Patients undergoing peri-operative XRT were identified. Complications and failure rates were analysed.

RESULTS: Over two years, 77 IBBRs were performed in 53 patients. In 2012, 11 patients underwent peri-operative XTR compared with five in 2013. Radiotherapy was significantly associated with higher reconstructive failure rates while pre-operative XRT was associated with more complications overall (p=0.0099). Over the two years, the number of IBBRs with any complication fell from 16 (43.2%) to 11 (27.5%) while reconstructive failure fell from six (16.2%) to four (10%).

CONCLUSIONS: Peri-operative XRT increases complication rates and reconstructive failure with IBBR. Our current policy of recommending autologous reconstruction if they have had pre-operative XRT seems to be resulting in decreased complication rates and increased reconstructive success.
