Stage II Carcinoma of the Endometrium

Abstract

Abstract A retrospective analysis is reported of 116 patients with Stage Il carcinoma of the endometrium treated definitively with combined radiation and total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) or irradiation alone from January 1960 through December 1981. At 5 and 10 years, the overall survival for all patients was 71 and 52% and the disease-free survival was 73 and 69%, respectively. Of 90 patients in the combined therapy group, most received a preoperative intracavitary insertion (3500 mgh to the uterus and 2000 mgh to the upper vagina) and preoperative external beam pelvic irradiation (2000 cGy whole pelvis, additional 3000 cGy to parametria, with midline shield) followed in 4 to 6 weeks by a TAH-BSO. The 5 and 10 year disease-free survival for this group was 78 and 75%, respectively. The incidence of major complications was 7% for the combined therapy group. Twenty-six patients were treated with irradiation alone; most of them received two intracavitary insertions (5000 mgh to the uterus and 3000 mgh to the upper vagina) and external beam pelvic irradiation (2000 cGy whole pelvis, additional 3000 cGy to parametria). The 5 and 10 year disease-free survival was 53 and 45%, respectively. The incidence of major complications was 19%. Factors found to influence the prognosis were histologic grade of tumor, clinical and histologic degree of tumor involvement of the ectocervix, presence of residual tumor in the hysterectomy specimen and the depth of myometrial invasion.
