[Growth rate of hepatocellular carcinoma and nutritional state].
To clarify the relationship between the growth rate of hepatocellular carcinoma (HCC) and nutritional state or liver function 32 HCC patients with a tumor volume less than 100 ml at the beginning of the study were investigated. These patients all had been treated by serial transcatheter arterial embolization (TAE). Tumor volume was measured by integrating the CT images of the liver before each TAE. The tumor at the TAE just before significant enlargement occurred was defined as the stage I tumor and it was designated stage II at the next TAE. The growth rate of the HCC was then calculated from the tumor volume at stage II minus that at stage I. Caloric intake, protein intake, liver function, and serum amino acid were determined in the patients at each stage. The results were as follows: 1) The tumor growth rate was greater in patients whose caloric intake and protein intake were more than 35 kcal/kg/day and 1.5 g/kg/day, respectively. 2) In patients with the greater tumor growth rate, the plasma BCAA/AAA ratio was the lower. However, after tumor growth, the ratio became higher, indicating that the growth of HCC decreased the requirement of BCAA. 3) The tumor growth rate correlated to the change of plasma arginine level (r = -0.76, p less than 0.05).
