Abstract

Purpose. We aimed to investigate whether systematic pelvic and paraaortic lymph node dissection delivers any survival advantage in a subgroup of patients with type II endometrial carcinoma and carcinosarcoma. Methods. We evaluated 135 patients with clinically early-stage (Stage I-II) type II endometrial carcinoma and carcinosarcoma who underwent systematic pelvic and paraaortic lymph node dissection or who did not undergo any lymph node dissection. Results. Overall survival (OS) and recurrence-free survivals (RFS) were significantly longer in the systematic lymph node dissection group (hazard ratio 0.28, 95% CI 0.13-0.62 p=0.002 for OS and hazard ratio 0.31, 95% CI 0.14-0.69 p=0.004 for RFS). Multivariate analysis showed that lymph node dissection, age, lymph node metastasis, and adjuvant therapy were independent prognostic variables of OS and RFS. Conclusions. Systematic pelvic and paraaortic lymph node dissection independently and significantly prolongs the survival of patients with early-stage type II endometrial carcinoma and carcinosarcoma.
