ObjectivesLaparoscopic hysterectomy is currently offered to a large number of patients, and assessing the noninferiority to abdominal hysterectomy with respect to clinical outcomes is key. We examine rates of recurrence, disease-free survival (DFS), and overall survival, and surgical complications of laparoscopic compared with abdominal hysterectomy for the treatment of early-stage endometrial cancer.MethodsElectronic databases were systematically searched to identify relevant studies, and patient characteristics and clinical outcomes extracted. The primary outcome was 3-year DFS, and estimates were pooled using an inverse-variance weighted meta-analysis.ResultsNine studies (4405 patients) were identified in which DFS was reported in 5 studies. The difference in 3-year DFS was 1.44% (95% confidence interval [CI], −0.65% to 3.53%) in favor of total abdominal hysterectomy, consistent with a noninferiority margin of 5%. Differences in DFS (hazard ratio, 1.10; 95% CI, 0.92–1.32), overall survival (hazard ratio, 1.16; 95% CI, 0.81–1.66), and local recurrence (difference, 0.42%; 95% CI, −0.41% to 1.25%) were not significant. Rates of intraoperative complications showed no difference (0.5%; 95% CI, −1.1% to 2.0%) based on 7 studies. There was a significant reduction in postoperative complications with the laparoscopic procedure (−6.83%; 95% CI, −9.19% to −4.47%).ConclusionsNoninferiority of laparoscopy was demonstrated on clinical outcomes and was associated with a reduction in postoperative complications. These results support continued treatment by laparoscopic hysterectomy for early-stage endometrial cancer.
