Multicentric Risk Evaluation of Autologous Fat Grafting Procedure

Multicentic Retrospective Evaluation of Risks in Mammary Carcinoma Relapse in Patients With Mammary Reconstruction and Autologous Fat Grafting

Autologous fat grafting, also known as lipofilling, is a surgical technique consisting in the processing and transfer of adipose tissue from one area in our organism (hips, thighs) to region which in need of reconstructive and aesthetic correction. The technique is frequently used after radical or conservative mammary surgery, aiming to achieve better aesthetic results, reduce pain induced by both surgery and radiotherapy. The scientific community was widely involved in the debate regarding the use of mesenchymal/stem cells in a patient with high risk of tumor progression due to their elevated proliferative profile. This study aims to retrospectively evaluate the oncological safety in the use of lipofilling in patients who underwent oncological and reconstructive treatment in our Institute.

Exclusion Criteria:
