Treatment of stage I adenocarcinoma of the endometrium by hysterectomy and adjuvant irradiation: a retrospective analysis of 304 patients.

Stokes S, Bedwinek J, Kao MS, et al.

Abstract:

Three hundred and four evaluable patients with FIGO Stage I adenocarcinoma of the endometrium were treated with hysterectomy and irradiation. Irradiation was preoperative in 250 and postoperative in 44 patients. Ten patients had a preoperative implant and postoperative external irradiation. The 5 year actuarial survival was 94%, 80% and 76% for grades 1, 2 and 3, respectively. Within each grade and for all patients there was no difference in survival for Stage IA versus IB. The initial failure rate was 26/304 (9%) with 2% of patients having only a pelvic failure, 2% pelvic and distal failure and 4% a distal failure only. There were four distal vaginal failures and no isolated cuff recurrences. The upper abdomen was the most frequent site of extra-pelvic failure for grade 3, while the periaortic nodes and lung constituted the most common sites of distal failure for grades 1 and 2 tumors. Timing of the hysterectomy following the irradiation was of importance when evaluating the prognostic significance of residual disease or depth of myometrial invasion. The presence of residual disease or greater than 1/3 myometrial invasion had a significantly worse prognosis only among patients who received no preoperative irradiation or who underwent their hysterectomy immediately following a preoperative implant. There was no difference in survival among patients with an initial local failure only as compared to those with an initial distal metastases, as the majority of patients with an initial local failure subsequently developed distant metastases.
