Impact of robotics on the outcome of elderly patients with endometrial cancer

Abstract

Objective: To evaluate the impact of introducing a robotics program on clinical outcome of elderly patients with endometrial cancer.

Methods: Evaluation and comparison of peri-operative morbidity and disease-free interval in 163 consecutive elderly patients (≥70years) with endometrial cancer undergoing staging procedure with traditional open surgery compared to robotic surgery.

Results: All consecutive patients ≥70years of age with endometrial cancer who underwent robotic surgery (n=113) were compared with all consecutive patients ≥70years of age (n=50) before the introduction of a robotic program in December 2007. Baseline patient characteristics were similar in both eras. Patients undergoing robotic surgery had longer mean operating times (244 compared with 217minutes, p=0.009) but fewer minor adverse events (17% compared with 60%, p<0.001). The robotics cohort had less estimated mean blood loss (75 vs 334mL, p<0.0001) and shorter mean hospital stay (3 vs 6days, p<0.0001). There was no difference in disease-free survival (p=0.61) during the mean follow-up time of 2years.

Conclusion: Transitioning from open surgery to a robotics program for the treatment of endometrial cancer in the elderly has significant benefits, including lower minor complication rate, less operative blood loss and shorter hospitalization without compromising 2-year disease-free survival.
