Total laparoscopic hysterectomy versus abdominal hysterectomy with lymphadenectomy for early-stage endometrial cancer: A prospective randomized study

Objective. The aim of this study was to compare, in a series of 159 women the feasibility, safety and morbidity of total laparoscopic hysterectomy (LPS) and abdominal hysterectomy with lymphadenectomy (LPT) for early-stage endometrial cancer and to assess disease-free survival and recurrence rate. Methods. 159 patients with clinical stage I endometrial cancer were enrolled in a prospective randomized trial and treated with LPS or LPT approach. The para-aortic lymphadenectomy was performed in all cases with positive pelvic lymph nodes discovered at frozen section evaluation, in patients with poorly differentiated tumors with myometrial invasion greater than 50% (ICG3), and non-endometrioid carcinomas. Results. The mean operative time was 136 min +/- 31 (95% CI 118-181) in the LPS group and 123 min +/- 29 (95% CI 111-198) in the LPT group (P < 0.01). The mean blood loss was 50 ml +/- 12 in the LPS Group (95% CI 20-90) and 145 ml +/- 35 in the LPT group (95% CI 60-255) (P < 0.01). The mean length of hospital stay was 5.1 +/- 1.2 in the LPT group (95% CI 1-7) and 2.1 +/- 0.5 in the LPS group (95% CI 1-5) (P < 0.01). Conclusions. Laparoscopy is a suitable procedure for the treatment of patients with early endometrial cancer and may offer the potential benefits of decreased discomfort with decreased convalescence time without compromising the degree of oncological radicality required; however, it does not seem to modify the disease-free survival and the overall survival, although multicenter randomized trials and long-term follow-up are required to evaluate the overall oncologic outcomes of this procedure.
