Abstract
INTRODUCTION
Breast reconstruction (BR) using a prosthesis implant (PI) associated with an acellular dermal matrix (ADM) is a known method that has been the subject of discussion in recent years. The objective of this study was to quantify the rate of PI removal after BR using prosthesis combined with ADM, and to identify the risk factors in the event of removal.
METHODS
This was a retrospective study conducted between 2010 and 2015. Inclusion criteria were patients who had undergone immediate (IBR) or delayed (DBR) breast reconstruction with placement of a PI associated with porcine ADM. The primary endpoint was the postoperative removal of the PI.
RESULTS
In all, 84 reconstructions were performed. The mean age of the population was 57.5 years. 25.9% of the patients were active smokers at the time of surgery. 89.5% of patients had previously benefited from ipsilateral breast radiation therapy (IBRT) in DBR, 10.5% in IBR. The PI deposition rate, all BR combined, was 21.4%. It was 52.17% in smokers and 9.84% in non-smokers (P<0.0001), making smoking an independent risk factor for reconstruction failure (hazard ratio (HR)=7.4, 95%CI [2.64-20.9]). IBRT was also a risk factor for PI removal, especially when performed after IBR (HR=8.1, 95%CI [1.1-62.1]).
CONCLUSION
Smoking and adjuvant IBRT are risk factors for failure of reconstruction by PI associated with ADM. This type of reconstruction should be selected for non-smokers who have not undergone IBRT and therefore could be a therapeutic alternative in the BR panel.
