Omega-3 fatty acid improves the clinical outcome of hepatectomized patients with hepatitis B virus (HBV)-associated hepatocellular carcinoma

摘要

Omega-3 fatty acid supplemented total parenteral nutrition improves the clinical outcome of patients undergoing certain operations;however,its benefits for patients with hepatitis type B virus(HBV)-associated hepatocellular carcinoma(HCC) who have undergone hepatectomy are still not clear.The aim of this study was to evaluate the effect of omega-3 fatty acid supplemented total parenteral nutrition on the clinical outcome of patients with HBV-associated HCC who underwent hepatectomy at our institution.A total of 63 patients with HBV-associated HCC who underwent hepatectomy were included in this study.These patients were randomly assigned to receive stand-ard total parenteral nutrition(the control group,n = 31) or omega-3 fatty acid supplemented total parenteral nutri-tion(the omega-3 fatty acid group,n = 32) for at least 5 d.The study endpoints were the occurrence of infection-related complications,recovery of liver function and length of hospital stay.The results showed that the omega-3 fatty acid group had a lower infection rate(omega-3 fatty acid,19.4% vs control,43.8%,P < 0.05),a better liver function after hepatectomy:alanine transaminase(omega-3 fatty acid,48.23±18.48 U/L vs control,73.34±40.60 U/L,P < 0.01),aspartate transaminase(omega-3 fatty acid,35.77±14.56 U/L vs control,50.53±24.62 U/L,P < 0.01),total bilirubin(omega-3 fatty acid,24.29±7.40 mmol/L vs control,28.37±8.06 mmol/L,P < 0.05) and a shorter length of hospital stay(omega-3 fatty acid,12.71±2.58 d vs control,15.91±3.23 d,P < 0.01).The serum contents of IL-6(omega-3 fatty acid,23.98±5.63 pg/mL vs control,35.55±7.5 pg/mL,P < 0.01) and TNF-α(ome-ga-3 fatty acid,4.43±1.22 pg/mL vs control,5.96±1.58 pg/mL,P < 0.01) after hepatectomy were significantly lower in the omega-3 fatty acid group than those of the control group.In conclusion,administration of omega-3 fatty acid may reduce infection rate and improve liver function recovery in HBV-associated HCC patients after hepatectomy.This improvement is associated with suppressed production of proinflammatory cytokines in these patients.
