[Indication of extended hepatectomy for liver cancer]

From the results of 95 cases of hepatectomy for liver cancer, including 67 cases of primary liver cancer, during the past 7 years in our department, the indication of extended hepatectomy for liver cancer was reviewed retrospectively, based on the pathological findings and functional reserve of the liver. 1. For curative resection, it is necessary to perform resection of larger segments than tumor existing area. 2. Morphologically, the extent of hepatectomy must be evaluated by the pathological findings such as the existence of tumor emboli in the portal vein, tumor capsule and daughter nodules, etc. 3. Functionally, resectability of the liver could be estimated preoperatively by total risk calculated from various liver function tests through multivariate analysis and the functional reserve (ICGmax) of the remnant liver. Furthermore, ICGRmax of unit liver volume is a good parameter of hepatic regeneration and long prognosis after hepatectomy.
