Results of resection and transplantation for hepatocellular carcinoma in cirrhosis and noncirrhosis

Abstract

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Both liver resection (LR) and orthotopic liver transplantation (OLT) are surgical treatment options depending on the size of the tumor and the presence of cirrhosis. Liver cirrhosis is the main reason for the high early postoperative mortality after resection. Even in the Child A stage, extensive resections are not recommended. This study presented the results of surgical treatment (LR or OLT) for HCC in cirrhotic and noncirrhotic livers. We analyzed the data of 76 patients who underwent LR or OLT for HCC from January 2001 to December 2006. In noncirrhotic livers the following resections were performed: 30 right and extended right hemihepatectomies (54.5%); 11 left hemihepatectomies (20%); and 14 mono- or bisegmentectomies (25.5%). In cirrhotic livers the following procedures were performed: in Child A stage 1 right hemihepatectomy, 1 extended right hemihepatectomy, 1 extended left hemihepatectomy, and 4 mono- or bisegmentectomies; and in Child B stage, 3 mono- or bisegmentectomies. Among 11 patients who underwent transplantation, tumors in 2 patients exceeded the Milan criteria. Five patients in the LR group were treated with transarterial chemoembolization before transplantation. LR for HCC in cirrhosis should be performed with caution; there were no long-term survivors in our data. Our study confirmed that OLT shows good long-term survival in early HCC stages. However, this may also be true for stages above the Milan criteria. For HCC in noncirrhotic livers, LR remains the treatment of choice, justifying an extensive surgical approach. Such an approach achieved favorable long term survivals.
