SIGNIFICANCE OF MAJOR HEPATECTOMY FOR METASTATIC LIVER MALIGNANCY

Major hepatectomies for 24 metastatic liver tumors including 13 of colo-rectum origin were performed. The cumulative survival rate in 23 cases excluding one case of operative death is 67.4%, 44.3% and 29.1% for 1, 3 and 5 year, respectively. The significant difference was observed in survival rate between H₁ (n=16) and H_2～3 (n =7). In colo-rectum origin group the survival rate of solitary H₁ was better than that of multiple H₁ significantly.
The Japanese Colon Cancer Research Meeting reported the relative survival rate of 33 cases of H₁ colorectum origin including 2 of hepatectomized cases. The survival rate of the present 11 hepatectomized cases in th same category is significantly better than that in the report of Colon Cancer Research Meeting, which shows utility of hepatectomy for H₁ metastatic tumor. Although in H_2～3 group 5 of 7 cases died within one year after hepatectomy, 2 particular cases survived 22 months and 57 months. The primary lesions of these two were leiomyosarcoma of the jujunum and carcinoid tumor of the lung. The indication for major hepatectomy for metastatic liver malignancy is the tumor of H₁, especially solitary and the slow growing or some kind of functioning tumor.
