Autologous fat grafting (AFG) has emerged as a useful technique in breast reconstruction. Utilizing a patient's own fat from areas like the abdomen or thighs, AFG serves various reconstruction needs. Nevertheless, the oncological safety of AFG in breast cancer patients has become a contentious issue. Concerns about its influence on cancer recurrence and detention have led to significant clinical debate and the need for thorough investigation. To determine the impact of autologous fat grafting (AFG) on loco-regional recurrence (LRR) in breast cancer survivors undergoing reconstruction, a comprehensive search of databases including PubMed, Medline, Web of Science, and Cochrane libraries was conducted from November 2023 through March 2024. This search adhered to the PRISMA guidelines and aimed to identify all the relevant studies on AFG in the context of breast reconstruction post cancer treatment. A meta-analysis was performed. Out of the studies reviewed, 40 met the inclusion criteria, with a total patient cohort of 14,078. The analysis revealed that AFG had no significant association with increased rates of LRR. According to the available literature, AFG is a safe reconstructive option for breast cancer patients and does not increase the risk of loco-regional recurrence. Nevertheless, further well-structured long-term prospective studies are required, since heterogeneity of available studies is high and requires standardization.
