Immediate breast volume replacement using a free dermal fat graft after breast cancer surgery: multi-institutional joint research of short-term outcomes in 262 Japanese patients
Abstract
Background: Immediate volume replacement using a free dermal fat graft (FDFG) has been proven safe with early postoperative benefits. The aims of the present study were to clarify adequate indications and risk factors associated with operative morbidity.
Patients and methods: A multi-institutional analysis of partial mastectomy with immediate volume replacement with FDFG was undertaken in 14 hospitals specializing in breast cancer treatment. Clinical and oncological variables were analyzed to identify factors associated with postoperative complications.
Results: A total of 262 cases were analyzed. Considering the observation period and overlap of patients, 13 (5.4%) out of 242 patients had complications within 1 month of surgery while 7 (4.6%) out of 151 patients developed complications 1-12 months after surgery. Two hundred and eleven out of 242 patients were statistically examined using a multivariate analysis, which revealed that the weight of resected breast tissue, size of implanted FDFG (cranio-caudal length), and weight of implanted FDFG were associated with a higher likelihood of postoperative complications.
Conclusions: Immediate breast volume replacement using a FDFG after breast cancer surgery should be done for selected patients with breast cancer to avoid postoperative complications. The prospective and larger investigations are warranted for the establishment of appropriate guidelines.
