The goal of this retrospective observational trial is to compare two different devices, used in implant-based breast reconstruction, called acellular dermal matrices, which are a sort of collagen patch that integrates with the tissues of the patient and helps in contrasting the collateral effects of radiotherapy (capsular contracture, implant loss) The main questions the study aims to answer are: * is one of the two matrices better than the other? (better results with fewer complications) * is there a group of patients who benefit more than another from the use of this type of devices? * is there an adm which works better in one specific subgroup of patients? Participants have undergone mastectomy, radiotherapy and implant reconstruction with the aid of two different kinds of acellular dermal matrices. Researchers will compare patients who receive the porcine-derived adm and the patients who receive bovine-derived adm to see if there is a difference in terms of capsular contracture reduction, aestethic result and complications.
