Abstract (original English)
Background Lipofilling is performed in breast cancer patients to optimize the aesthetic outcome following breast reconstruction after mastectomy. Despite its common usage worldwide, little is known about the interaction of the lipoaspirate and dormant cancer cells. Up to date, no risk factors that increase the risk for cancer recurrence have been established. This study aims to identify risk factors for lipofilling candidates after breast cancer and questions the oncological safety of lipofilling in lymph node positive disease. Methods Matched retrospective cohort study: the disease-free survival (DFS) between 100 breast cancer patients undergoing a lipofilling after their DIEP-flap reconstruction and 100 matched control patients with no subsequent lipofilling was analyzed. Further, patients were subdivided according to risk factors, which were categorized as patient-dependent factors (PDFs) and tumor-dependent factors (TDFs). DFS and hazard ratios (HR) were compared to identify potential risk factors that may increase cancer recurrence. Results Median follow-up was 76.5 months from the mastectomy, and 31 months from the startpoint to the end of follow-up. Seven and eleven patients had recurrence in the lipofilling and control group, respectively, presenting with comparable DFS rates and an insignificant HR =0.57, 95% confidence interval (CI): 0.22-1.47, P=0.24. According to su
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • Without an adequate control group, treatment effects cannot be separated from other factors.
