Clinical application of immediate prepectoral implant-based breast reconstruction with TiLoop Bra after skin-sparing or nipple-areola-complex-sparing mastectomy for breast cancer patients / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective To explore the surgical technique and preliminary safety and aesthetics results of immediate prepectoral implant-based breast reconstruction (BR) with titanium-coated polypropylene mesh (TiLoop Bra) after skin-sparing mastectomy (SSM) or nipple-areola-complex-sparing mastectomy (NSM) for breast cancer patients. Methods The clinical data of consecutive patients who underwent immediate prepectoral implant-based BR with TiLoop Bra after SSM or NSM in West China Hospital from January to July 2022 were retrospectively analyzed. The operation time, intraoperative blood loss, early complication were collected. The preliminary aesthetics results were assessed with the Ueda score and Harris score. Results All the patients were female with a mean age of 39.0±6.8 years. One patient had bilateral breast malignant tumors, and the others had unilateral malignant tumors. Six patients received neoadjuvant chemotherapy before surgery. The mean diameter of the tumors was 24.4±11.9 mm under the color ultrasound before the neoadjuvant chemotherapy. The mean operation time was 153.9±49.4 min. The mean intraoperative blood loss was 29.2±18.3 mL. There were 3 patients with tumor stage 0, 10 patients with stage Ⅰ, 6 patients with stage Ⅱ, 3 patients with stage Ⅲ and 1 patient was found no residual cancer after neoadjuvant chemotherapy. All the patients were successfully followed up with a median follow-up time of 4.8 (3.0-9.2) months. There were 2 (8.3%) patients with major complications, including 1 wound dehiscence and 1 hematoma, and 4 (16.7%) minor complications, including 2 wound dehiscence and 2 infection. The patients with excellent and good Ueda score and Harris score accounted for 82.6% and 87.0%, respectively. None of the patients had animation deformity, capsular contracture, nipple-areola or skin flaps necrosis, or implant loss. During the follow-up period, no local/regional recurrence or distant metastasis was found. Conclusion For selected reliable patients, immediate prepectoral implant-based BR with TiLoop Bra after SSM or NSM for breast cancer patients is safe and has good aesthetics results in the early postoperative period. It has broad application space in patients with suitable indications, and can be promoted as a routine operation.
