Hepatectomy for metastatic liver tumor.
Hepatectomy for liver metastasis from the colo-rectum and other organs was performed in 77 cases at the National Cancer Center Hospital. The operative procedures included every variety of hepatectomy from extended resection as trisegmentectomy to small resection as partial resection. The operative mortality rate was 3.9% (3/77). The overall cumulative 5-year survival rate was 26.7 +/- 13.9% (survival rate +/- Greenwood's 5% standard error). The long-term survival of the patients with unilobular metastasis (H1) was better than that of bilobular (H2) and disseminated (H3 metastasis). When H1 was divided into solitary unilobular metastasis (H1 solitary) and multiple unilobular metastasis (H1 multiple), the prognosis for the former was better than for the latter after hepatectomy. The long-term survival of patients with H1 multiple was the same as that of patients with H2 and H3; that means that one of the factors affecting prognosis after hepatectomy is whether the tumor is solitary or multiple.
