The preoperative diagnosis of hepatic metastases in cases of colorectal carcinoma

Abstract
Nged from 74 to 84 per cent. The false-negative rates were acceptably low (9-13 per cent) for all but the CPK determination. The false-positive rates were unacceptably high for all four tests (38 to 60 per cent). A “metastatic score” for reducing the high false-positive rate is described. In view of the high false-positive rates of preoperative screening tests, laparotomy is presently the most accurate method of diagnosing hepatic metastases.
