Survival analysis of robotic versus traditional laparoscopic surgical staging for endometrial cancer

Abstract

Objective The purpose of this study was to compare the survival of women with endometrial cancer managed by robotic- and laparoscopic-assisted surgery. Study Design This was a retrospective study conducted at 2 academic centers. Primary outcomes were overall survival, disease-free survival (DFS), and disease recurrence. Results From 2003 through 2010, 415 women met the study criteria. A total of 183 women had robotic and 232 women had laparoscopic-assisted surgery. Both groups were comparable in age, body mass index, comorbid conditions, histology, surgical stage, tumor grade, total nodes retrieved, and adjuvant therapy. With a median follow-up of 38 months (range, 4-61 months) for the robotic and 58 months (range, 4-118 months) for the traditional laparoscopic group, there were no significant differences in survival (3-year survival 93.3% and 93.6%), DFS (3-year DFS 83.3% and 88.4%), and tumor recurrence (14.8% and 12.1%) for robotic and laparoscopic groups, respectively. Univariate and multivariate analysis showed that surgery is not an independent prognostic factor of survival. Conclusion Robotic-assisted surgery yields equivalent oncologic outcomes when compared to traditional laparoscopic surgery for endometrial adenocarcinoma. © 2014 Mosby, Inc. All rights reserved.
