| Abstract: | From 1969 to 1979, 300 patients with the diagnosis of endometrial cancer operated elsewhere were referred for treatment to the Department of Radiation Oncology at Memorial Sloan-Kettering Cancer Center. All the patients were staged according to FIGO classification. One hundred and seventy-three patients were Stage IA, 105 patients were Stage IB, and 22 patients were Stage II. Within Stage IA, 141 patients had well differentiated tumor (G1), 20 had moderately well differentiated tumor (G2) and 12 patients had poorly differentiated (G3). One hundred and thirty-three :patients had superficial myometrial invasion and 40 patients had deep myometrial invasion. Within Stage IB, 69 patients had G1 tumor, 23 had G2, and 13 had G3 tumors. Seventy-four patients in this group had superficial myometrial invasion and 31 patients had deep myometrial invasion. Two hundred and eighty-three patients had adenocarcinoma, 13 patients had adenoacanthoma, 4 patients had adenosquamous and other histological types. All of the patients received combined surgery (total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH/BSO) and radiation. The radiation treatments consisted of external pelvic radiation and intravaginal vault radiation. External pelvic radiation was delivered with a megavoltage apparatus for a total dose of 4,000 cGy in 4 weeks preoperatively (47 patients) or postoperatively (105 patients) in patients presenting with high grade (G2, G3), more than 1 3 myometrial invasion, Stage II and extrauterine extension of disease at surgery. All patients received in addition, postoperative intravaginal vault irradiation consisting of 2100 cGy in 3 fractions over 4 weeks with a high dose rate remote afterloading technique. The follow-up in these patients ranged from 5-14 years. Survival data was calculated according to Kaplan-Meier Method and Cox regression multivariate analysis to identify the prognostic factors. The 10-year survival rate in Stage IA was 91%; in Stage IB 75%; and in Stage II it was 71%. Eleven patients (4%) developed recurrent disease with either local and/or distant metastasis. Nine-percent of the patients developed mild to moderate complications which resolved with conservative conservative treatment. Patients with gross extra-uterine pelvic extension of disease had a poor survival compared with those presenting with microscopic involvement (40% vs. 80% at 5-years). No statistically significant difference in survival was observed between patients who received either preoperative or postoperative external pelvic irradiation. Multivariate analysis demonstrated that grade, stage, age, and extra-uterine extension of the disease at the time of hysterectomy are the most important prognostic factors. © 1997. |
