Serum kynurenine levels are a novel biomarker to predict the prognosis of patients with hepatocellular carcinoma

Cumulative survival rates of HCC according to the kynurenine level, stratified by BCLC stage.
Cumulative survival rates of HCC according to the kynurenine level were analyzed using Kaplan-Meier’s method. Black solid, gray solid, and dotted lines indicate stratified kynurenine levels of <600, 600–899, and ≧900 ng/mL, respectively. In BCLC stage 0 and A, survival rates differed significantly among the three groups by the log-rank test, increasing along with the kynurenine level.
