317P - Endoscopic Assisted Mastectomy with Immediate Reconstruction in Treatment of Early Breast Cancer-Experience from Taiwan

Abstract

ABSTRACT Aim: Endoscopic assisted breast surgery (EABS), performed through minimal axillary and/or peri-areolar incisions, could be another option for the management breast cancer. In this study, we report our preliminary results of EABS in the National Cheng-Kung University Hospital (NCKUH), Taipei Medical University Hospital (TMUH) and Changhua Christian Hospital (CCH), Taiwan. Methods: Patients with breast cancer managed by EABS were search from 3 medical centers database. The patients' clinicopathologic characteristics, type of surgery, method of breast reconstruction, complication and recurrence were recorded. (IRB Nr 121229) Results: A total of 220 patients with breast cancer undergone EABS from the above three endoscopic breast surgery centers in Taiwan. All of them were female, and the mean age at diagnosis was 49.5 ± 10.1 years old (range 26 to 80 year). Among these 220 patients, 36(16.4%) underwent endoscopic assisted partial mastectomy (EAPM), and 184 received endoscopic assisted total mastectomy (EATM). In the 184 EATM patients, 46 (25%) received endoscopic assisted skin sparing mastectomy (E-SSM), and 138 (75%) underwent endoscopic assisted nipple sparing mastectomy (E-NSM). The mean pathologic tumor size of these 220 patients was 2.1 ± 1.6 cm (0.1 to 8.5 cm). Lymph node metastasis was found in 33 (15%) patients, 17 patients with lymph node 1-3 positive, and 16 patient with 4-9 lymph nodes metastasis. The post operative stage distribution were 70 (31.8%) ductal carcinoma in situ (DCIS), 75 (34.1%) stage 1, 36(16.4%) stage 2a, 26(11.8%) stage 2b, and 13 (5.9%) stage 3a.Among the 184 EATM patients, 147 (79.9%) received immediate breast reconstruction. Most (57.3%) of them received Gel implant reconstruction, and 42.7% received breast reconstruction with autologous pedicled transverse abdominal myocutaneous (TRAM) flap. Complications (9.6%) follow EABS were all minor, and most of them were wound related. The cosmetic result was scored by surgeons and patients. Conclusions: Endoscopic assisted breast surgery is a safe and highly acceptable operation for the management of Taiwanese women with early stage breast cancer.
