The use of acellular dermal matrix (ADM) in implant-based breast reconstructions (IBBRs) is established practice. Existing evidence validating ADMs proposed advantages, including improved cosmetics and more single-stage IBBRs, is lacking.

This was an open-label, multicenter, randomized clinical trial of women with primary breast cancer who planned for mastectomy and immediate IBBR, with a 2-year follow-up for all participants. Participants were enrolled at 5 breast cancer units in Sweden and the United Kingdom between 2014 and May 2017. Exclusion criteria included previous radiotherapy and neo-adjuvant chemotherapy. Data were analyzed until August 2017.

Immediate IBBR with ADM did not yield fewer reoperations compared with conventional IBBR without ADM, nor was IBBR with ADM superior in terms of HRQoL or patient-reported cosmetic outcomes. Patients treated for breast cancer contemplating ADM-supported IBBR should be informed about the lack of evidence validating ADM's suggested benefits.
