Abstract

Objective. The purpose of this study was to assess the value of computed tomography (CT) scans in predicting preoperatively the depth of invasion and extrauterine spread in patients with endometrial cancer. Methods. The records of 54 patients with endometrial cancer who underwent a preoperative CT scan and surgical treatment (36 of whom had complete surgical staging) were reviewed. Final pathological findings were compared with those of the CT scan. The ability of the CT scan to detect the depth of invasion of the tumor into the myometrium and extrauterine spread was assessed. Results. The sensitivity of CT scans at predicting the depth of myometrial invasion (none, inner half, outer half) and cervical and parametrial spread was 10, 9, and 17%, respectively, and sensitivity in predicting any degree of myometrial invasion, lymph node metastasis, adnexal involvement, and the presence of malignant cells in peritoneal cytology was 61, 50, 60 and 57%, respectively. Conclusion. CT scan has limited usefulness in determining the depth of myometrial invasion or extent of tumor spread in patients with endometrial cancer. Its routine preoperative use is difficult to justify. (C) 2000 Academic Press.
