Absence of colorectal cancer metastasis to the cirrhotic liver.

Hepatic metastasis of colorectal cancer was found in 40 (16%) of 250 patients with colorectal cancer treated in our department during the past 5 years. Liver cirrhosis was not found among the 40 patients with metastases (16%) but was present in 46 (21.9%) of the 210 nonmetastatic patients, with a significant difference between the two groups (p less than 0.001). The rate of patients who were positive for hepatitis B surface antibody was 10% in the metastatic group and 34.3% in the nonmetastatic group, with a significant difference (p less than 0.01). These findings suggest that colorectal cancer does not metastasize to the injured liver, especially the cirrhotic liver.
