title: Hysterectomy and adjuvant irradiation for pathologic stage III adenocarcinoma of the endometrium.
abstract: Three hundred and four evaluable patients with FIGO clinical Stage I adenocarcinoma of the endometrium were treated with hysterectomy and adjuvant irradiation. At surgery, 15 patients (5%) were found to have disease outside the uterus, but within the pelvis Pathologic Stage III (PSIII). A higher grade of tumor was not associated with an increase in the frequency of PSIII, being 7/158 (4%), 5/89 (6%), and 3/57 (5%) for Grades 1, 2, and 3 respectively. Depth of myometrial invasion correlated with PSIII disease in 5/69 (7%) for less than 1/3 myometrial invasion versus 7/33 (21%) for greater than 1/3 invasion (p = .05). One patient died of intercurrent disease at 4 months with 6/14 (43%) of the remaining patients developing recurrent disease. The site of initial failure was pelvis 1/15 (7%), pelvis and distant metastasis 3/15 (20%), and distant metastasis alone 2/15 (13%). Of seven patients who received external pelvic irradiation, there was one local failure (14%), which is not statistically significant from the 3/8 (38%) local failure rate among patients not receiving external pelvic irradiation (p = .569). None of the seven patients experienced a treatment related complication as a result of adjuvant irradiation.
