It was previously reported about the surgical outcome and effectiveness of UAS based on a randomized controlled trial of 256 patients with gastric cancer. We aimed to clarify the long-term oncological safety of the use of UAS in the aspect of overall survival and recurrence.Methods： Gastric cancer patients who underwent gastrectomy with D2 lymph node dissection were enrolled and randomly assigned to either the conventional surgery group （n=125） or the UAS group （n=128）. Survival, recurrence and long-term postoperative complications were compared between the two groups. The median follow-up period was 56 months.Results： Gastric cancer-related death was higher in patients of the UAS group compared with the conventional group （P=0.019）. Overall survival rates stratified by stage were not significantly different between the two groups （P=0.170）. Disease-free survival rates stratified by stage and recurrence-free survival rates of gastric cancer were similar between the conventional group and the UAS group （P=0.313 and 0.199, respectively）. The postoperative complication rate was not significantly different between the groups （P=1.000）. Conclusions： It is suggested that the use of UAS in gastrectomy for gastric cancer showed oncologically acceptable safety compared with conventional electric instruments even in long-term period.展开更多

Objective: We evaluate the oncological safety of oncoplastic breast surgery (OS) in LABC showing partial response to NCT. Methods: We prospectively analyzed the data of 32 out of 58 patients with LABC who showed partial response to NCT and could have conservative surgery with advanced oncoplastic techniques rather than total mastectomy. Results: Out of 58 patients with LABC, received neoadjuvant chemotherapy, complete response was observed in 8 patients (13%), partial response reported in 32 (55.1%) cases, 12 patients (20%) had stable disease and 6 patients (10%) showed progressive disease. Data of 32 cases were studied (mean age 44.84 ± 9.10 years;range 26 - 59 years). Inferior pedicle was performed in 9 cases, mini LD flap in 3 patients, 5 had Grissotti technique, 6 with superomedial pedicle, 4 had V mammoplasty and 3 with J mammoplasty and 2 had vertical mammoplasty. Margins were positive in 5 cases (15.6%) with mean margin width 9.63 ± 5.72 (range 0 - 22 mm), and the local recurrence was reported in 2 cases (6.2%). Complications were reported in 3 cases (9.3%). The follow up was 1.67 ± 1.03 (range 0 - 3.3 years). Conclusions: Integration of neoadjuvant chemotherapy together with advanced oncoplastic techniques opens a new way for management of LABC especially those showing partial response with avoidance of total mastectomy, and comparable oncological safety in addition to better aesthetic and psychological outcome.展开更多
