Measurement of high molecular weight forms of enzymes in serum in the detection of hepatic metastases of colorectal cancer.
Total gamma-glutamyl transferase and alkaline phosphatase, liver-specific alkaline phosphatase and high molecular weight forms of the two enzymes were measured in the sera of 42 patients with colorectal cancer, of whom 26 were apparently metastases-free and 16 had palpable liver metastases. The aver...
