title: Adenocarcinoma of the endometrium. Analysis of 256 cases with disease limited to the uterine corpus: treatment comparisons.
abstract: Between 1959 and 1975, 256 patients with pathologic Stage I uterine adenocarcinoma were treated at Stanford University Hospital, Stanford, California. One hundred ninety-three patients were initially treated with surgery, and 63 received preoperative radium, reflecting different treatment philosophies of physicians operating at Stanford. Relapse rates for the two treatment groups were 9% (17 of 193) and 14% (9 of 63), respectively (P = 0.24). In both groups of patients, relapse rates were correlated with grade, although for those treated with initial surgery myometrial invasion was a much better predictor of relapse. Only one of the 127 patients without demonstrable myometrial invasion suffered a possible relapse. Sixteen of 66 patients with myometrial invasion (24%) relapsed after treatment. A review of the histologic material revealed 26 of 256 cases with a special histologic variant termed uterine papillary serous carcinoma, which was associated with a high relapse rate (50%) and a marked tendency for upper abdominal spread. It was found that the use of preoperative intracavitary radium was not demonstrated to be of value. Histologic information obtained from the hysterectomy specimen can be used to determine patients at high risk for relapse who may benefit from adjuvant treatment based on our understanding of the natural history of endometrial carcinoma.
