[Computed tomography in the diagnosis of metastases of colon cancer]

The authors present the results of preoperative diagnosis of metastases to the liver and retroperitoneal lymph nodes in colon cancer patients using computerized tomography (CT). Comparing CT and liver scanning the first method proved to be four times more effective. False positive and false negative results in CT were obtained in 11%, in liver scanning in 25.7%. CT made it possible to specify not only the dissemination of a tumor process but also to detect some concomitant diseases. CT can be used for a dynamic control over the efficacy of the treatment of cancer patients.
