[Role of X-ray CT in the evaluation of extension of ovarian cancer].
To evaluate the utility of X-ray computed tomography (CT) in the management of malignant ovarian tumor, preoperative CT of 89 patients with ovarian cancer were analyzed on the basis of their surgically confirmed findings. Relationships between CT findings and clinical factors such as actual tumor spread, stage, and accomplished surgery were studied. The results obtained were as follows. 1. The rates of correct diagnosis in tumor spread were 79.8% for tumor growth on the external surface of the ovary, 77.6% for involvement of both ovaries, 79.8% for ascites, 78.2% for metastasis to the uterus, 68.2% for peritoneal metastasis, 77.0% for metastasis to the intestine, and 79.3% for the metastasis to the omentum. 2. Comparing the stage suggested by CT (CT stage) and the stage revealed by surgery (surgical stage), the stages coincided in 57 patients (64.0%). CT stages were overestimated in 9 cases and underestimated in 23 cases. 3. As for the practicability of surgery, either complete or standard operation was performed in 31 of 33 cases (93.9%) of CT stage I, 21 of 28 (75.0%) of CT stage II, and 11 of 28 (39.3%) of CT stage III. The possibility of accomplishing surgery was very low when CT indicated stage III disease.
