Among 187 patients with liver metastasis, 137 patients (12.6%) had liver metastases identified at the time of resection of the primary tumors, and another 50 patients developed hepatic metastases after curative resection. According to the extent of liver metastasis at the time of primary tumors, the difference of survival of the three categories (namely H1, H2, H3) was significant (p<0.01, long-rank test). Survival of 27 patients with H1 metastasis which were resected at the time of the initial surgery, was better than 23 pateints with H1 metastasis which were non-resected. There were 36 patients with resected liver metastases in this series, who consist of 27 patients with synchronous liver metastasis and 9 patients with recurrent liver metastases. Among these patients, survival in 26 patients with solitary lesion was better than 10 patients with mul-tiple metastatic lesions. We revealed the usefulness of surgical treatment and discussed operative indicatis for liver metastasis from colo-rectal carcinoma.
