Abstract
BACKGROUND & AIMS: Chronic liver diseases, including hepatocellular carcinoma (HCC), lead to an imbalance in energy metabolism. The non-protein respiratory quotient (npRQ), which estimates energy malnutrition, can be evaluated using an indirect calorimeter; however, npRQ measurement is limited in routine work. This study aimed to investigate the relationship between the albumin-bilirubin (ALBI) score and npRQ in patients with HCC. METHODS: We conducted a retrospective cohort study in 109 patients with HCC who underwent indirect calorimetry and then compared the npRQ with various clinical parameters, including liver function and tumor factors. RESULTS: The median npRQ was 0.82. A significant negative correlation was found between the npRQ and the ALBI score (r = -0.35, p < 0.001). The median npRQ in modified ALBI (mALBI) grades 1, 2a, 2b, and 3 were 0.84, 0.86, 0.81, and 0.79, respectively (grade 2a vs. 2b, p = 0.002). Factors associated with npRQ <0.85, which is reported to be the best cutoff value for energy malnutrition, were analyzed. On multivariate analysis, the ALBI score (cutoff value, -2.18) was the only significant independent factor (odds ratio, 7.65; p < 0.001). The proportion of HCC patients with npRQ <0.85 significantly increased among patients with an ALBI score ≥-2.18 (45/51, 88.2%) compared with those with an ALBI score <-2.18 (29/58, 50%) (p < 0.001). CONCLUSIONS: The ALBI score might be a useful predictor for energy malnutrition in patients with HCC. In addition, most HCC patients with mALBI grade 2b or 3 can be considered to have energy malnutrition.
