[Surgical treatment of hepatocellular carcinoma]

The surgical treatment for hepatocellular carcinoma must be chosen by considering some factors such as liver function, position and involved area of the tumor. This article reports our guide line for surgical treatment based on liver function and long term survival. In severe cirrhotic patient with ICG retention rate ranging 30 to 40%, hepatectomy can be indicated only when they mach several conditions as follows; KICG from 0.06 to 0.08, superficially located tumor removal by resection of small area with curability. In patients with ICG retention rate lower then 30%, resection range is determined by the multiple regression equation indicating safety limit of hepatectomy. The predictability of the equation has been as high as 93%, the long term survival depends on following factor, i.e.; tumor size, VP factor, and IM factor. Hepatectomy should be first option when the tumor is less than 5 cm in size, VPO, IMO, and can be safely removable with segmentectomy or larger resection.
