- Abstract
- BACKGROUND: It is widely accepted that both autologous and alloplastic reconstruction are safe. A recent publication reported a significant association between textured implants and metastatic recurrence of breast cancer. This study aims to assess if the published results are reproducible in our cohort and to review the safety of breast reconstruction. METHODS: This is a retrospective cohort study of adult patients undergoing mastectomy and either alloplastic or autologous breast reconstruction at a single quaternary hospital. Outcomes include disease free survival (DFS), local and recurrence free survival (LRRFS) and BIA-ALCL. For time to event endpoints, unadjusted and multivariate adjusted hazard ratios (HRs) were estimated using Cox regression, and penalized Cox regression respectively. RESULTS: Four hundred and twenty-six patients of whom 187 underwent autologous reconstruction and 239 underwent alloplastic. There were 43 cancer recurrences (24 alloplastic and 19 autologous) and 14 local regional recurrences (8 alloplastic and 4 autologous). There were 26 deaths and no instances of BIA-ALCL. Median follow-up time was 4.7 years. No evidence of association was found between breast reconstruction method and DFS (HR 0.87 CI: 0.47-1.58). It is uncertain whether implant texture grade was associated with increased breast cancer recurrence (HR 2.17 CI: 0.65-7.52). CONCLUSION: Both autologous and alloplastic breast reconstruction have been carried out in our cohort and reconstructive modality was not associated with either reduced DFS or LRRFS. The results in this cohort show there is uncertainty between the use of textured breast implants and either local or distant breast cancer recurrence.
