Abstract

Recurrent endometrial carcinoma, even when clinically confined to the vagina or pelvis, is associated with poor survival. Pelvic radiotherapy for patients with localized recurrences who have not been previously irradiated has not been highly effective. Our hypothesis was that local salvage therapy fails because a significant number of patients have occult, subclinical distant metastases at the time of relapse. In order to accurately assess disease status at the time of the recurrence, we prospectively evaluated eight patients with recurrent disease limited to the vagina/pelvis by physical examination, routine laboratory tests, and radiologic imaging. All patients underwent a "staging" procedure which included laparotomy, selective pelvic/periaortic lymphadenectomy, peritoneal biopsies, and washings. Three (37.5%) of eight patients had upper abdominal disease found at laparotomy (95% confidence interval 0.11 to 0.71). Presence of subclinical metastases was associated with larger tumor size (> or = 2 cm) and elevated serum CA 125 antigen levels. Treatment was modified in three patients according to the results of surgical staging. One patient was treated with chemotherapy while two patients received whole-abdominal radiation in addition to pelvic fields. Seven of eight patients are alive 21 to 61 months following salvage therapy. Three (43%) of seven patients treated with radiotherapy suffered nonneoplastic bowel obstruction requiring laparotomy at 3, 6, and 15 weeks following completion of radiation therapy. Since 37.5% of patients with recurrent endometrial carcinoma clinically confined to the pelvis had occult upper abdominal disease, surgical reassessment may be warranted, especially in those with elevated serum CA 125 levels or large tumors. Our limited sample size precludes any definitive conclusions regarding our data. Further research will determine the frequency of subclinical metastases and the value of serum CA 125 levels in assessing disease status.
