Importance of branched-chain amino acids in patients with liver cirrhosis and advanced hepatocellular carcinoma receiving hepatic arterial infusion chemotherapy.

Abstract

The aim of this retrospective cohort study was to clarify the effect of a branched-chain amino acids (BCAA) on the liver function and the prognosis of Child-Pugh class (C-P) A and B liver cirrhosis (LC) patients with advanced hepatocellular carcinoma (aHCC) undergoing hepatic arterial infusion chemotherapy (HAIC). Ninety-two adult Japanese patients with LC and aHCC underwent HAIC. They were in C-P A or B, and they showed multiple partial responses or stable disease. We excluded 11 patients classified as C-P C and 47 patients who showed no response. The patients were divided into an HAIC group receiving HAIC alone (n = 43) and a BCAA group treated with HAIC plus BCAA (n = 49). HAIC was delivered via the proper hepatic artery. The BCAA group also received oral administration of BCAA. In the BCAA group, serum albumin increased significantly after HAIC, while there were no significant changes in serum total bilirubin, serum aminotransferases, prothrombin time, ascites, and hepatic encephalopathy. The C-P score decreased significantly after HAIC compared with before HAIC in C-P B patients, although there was no significant change in C-P A patients. Survival of the BCAA group was significantly longer than that of the HAIC group, with the median survival time being 426 versus 272 days for C-P B patients, although there was no significant difference for C-P A patients. Branched-chain amino acids might improve the survival and C-P score by increasing serum albumin in C-P B patients with aHCC receiving HAIC.
