Summary

The Department of Plastic Surgery at Middlemore Hospital has found that the complication rate of patients having implant-based breast reconstruction after radiotherapy for breast cancer treatment have a high complication rate. We now encourage patients to use their own tissue (for example, from their abdomen) to reconstruct their breast(s) if they have had radiotherapy. We have shown a lower complication rate in women who use their own tissue rather than implants for reconstruction following radiotherapy.

Abstract

Aim

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.

Method

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%).

Conclusion

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.
