Pelvic and para-aortic lymphadenectomy for surgical staging of endometrial cancer: morbidity and mortality.

Abstract

This analysis compared retrospectively the morbidity and mortality of patients with endometrial cancer who had total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH/BSO) alone or with pelvic and para-aortic lymphadenectomy performed by the same surgeon at one private institution. Between August 1987 and March 1991, 77 women with endometrial cancer were staged surgically by a standard protocol without preoperative radiotherapy. Thirty-five patients (45%) had TAH/BSO alone and 42 (55%) had TAH/BSO with pelvic and para-aortic lymphadenectomy. The median number of lymph nodes removed was 18. Patients having lymphadenectomy had an increased mean (+/- standard deviation) operative time (129 +/- 29 versus 87 +/- 26 minutes; P less than .0001), increased mean estimated blood loss (391 +/- 192 versus 272 +/- 219 mL; P = .013), and a longer postoperative hospital stay (P = .017) compared with patients having TAH/BSO alone. However, there was no difference in transfusion rate, febrile morbidity, postoperative complications, or mortality. We conclude that pelvic and para-aortic lymphadenectomy can be added to TAH/BSO in patients with endometrial cancer without a clinically significant increase in morbidity or mortality.
