Parametrial spread in patients with endometrial carcinoma undergoing radical hysterectomy

The objective of this paper is to study parametrial involvement in patients with endometrial carcinoma undergoing radical hysterectomy. We reviewed indications for surgery, pathology findings, and outcome of a series of 24 patients with endometrial carcinoma who underwent radical hysterectomy. The uterus, cervix and parametrial tissue were processed as step-serial sections. Histologically, 16 patients (67%) had carcinoma involving the cervix. Two of these patients (8%) had frank histologic parametrial involvement and four (17%) had disease extending to the transitional zone of the cervix. Parametrial involvement was continuous and seen only in patients with involvement of the cervical stroma. Six patients (25%) had pelvic node metastases. With a median follow-up of 53 months (range 2-140), four patients (17%) developed recurrences (all within 24 months). Twelve patients (50%), including one of the two with parametrial invasion, were free of disease for 5 years or longer. We conclude that direct parametrial extension can occur in locally advanced endometrial cancer. Radical hysterectomy with lymphadenectomy can be an adequate operation for such patients.
