Use of angio computed tomography to evaluate extent of endometrial carcinoma.
Patients with endometrial carcinoma underwent angio computed tomography (CT) prior to surgery to evaluate the extent of the carcinoma. The subjects of the study were 87 patients operated on at the Cancer Institute Hospital during the period 1983 to 1986. After preoperative bilateral internal iliac angiography, angio CT was performed using the already inserted catheters. Although the intact uterine wall was enhanced by the angio CT, the cancerous lesion was not, which permitted easy recognition of the cancerous lesion as a low-density area. To evaluate the degree of myometrial invasion, the minimal thickness of intact uterine wall was measured in the CT image, and was compared later with findings from the operative materials. The comparison showed that for all the patients, the minimal thickness of the intact uterine wall as shown in the CT image was comparable to the actual minimal thickness of the operative materials. Because depth of myometrial invasion is known as an important prognostic factor, measurement of the minimal thickness of the intact uterine wall as shown in the CT image is useful as an objective prognostic factor. Angio CT facilitates recognition of myometrial invasion preoperatively.
