Background Liver cirrhosis is a state of protein calorie malnutrition
which may induce various complications. This study aimed to elucidate
if long-term nutritional support with branched chain amino acids (BCAA
s) is effective after hepatic resection for hepatocellular carcinoma (
HCC). Methods Between 2 and 3 weeks after operation, 75 patients were
randomized to receive oral BCAAs (Aminoleban EN) 100 g per day for 1 y
ear, and another 75 patients were assigned to a control group. Mean fo
llow-up times were 35.8 months and 36.0 months respectively. Results F
lapping tremor was less common, body-weight was greater and performanc
e status was better in the BCAA-treated group throughout the 1-year pe
riod. BCAA treatment significantly increased red blood cell and serum
albumin level in patients with Child grade B and C disease. Substantia
lly similar effects were observed in those with major hepatic resectio
n. Higher Fischer molar ratios were maintained in the treated group. H
owever, there were no differences in cumulative tumour recurrence and
survival rates. Conclusion Long-term oral nutritional support with BCA
As after resection of HCC is beneficial in improving clinical features
and laboratory data without increasing the rate of tumour recurrence,
particularly in patients with advanced cirrhosis or after major hepat
ic resection.
