Easy Clinical Predictor For Low Bcaa To Tyrosine Ratio In Chronic Liver Disease Patients With Hepatocellular Carcinoma: Usefulness Of Albi Score As Nutritional Prognostic Marker

Background/Aim Low branched-chain amino acid (BCAA) to tyrosine ratio (BTR) is known as an indicator of amino acid imbalance. We elucidated usefulness of newly developed albumin-bilirubin (ALBI) score as alternative methods of BTR in patients with naive hepatocellular carcinoma (HCC) retrospectively.Materials/Methods In 842 patients with HCC and without BCAA supplementation (71 years, male 614, Child-Pugh A:B:C = 689:116:37), relationships among BTR and clinical features were evaluated. Of those, 438 patients, with Milan criteria HCC, treated curatively were divided into the high-BTR (>4.4) (n = 293) and low-BTR (<= 4.4) (n = 145) groups. The prognostic value of BTR was evaluated using inverse probability weighting (IPW) with propensity score.Results The low-BTR group showed worse prognosis than the other (3-, 5-, 10-year overall survival rates: 88.9% vs. 86.3%/70.5% vs. 78.1%/38.1% vs. 52.3%, respectively; p < 0.001). Multivariate Cox-hazard analysis adjusted for IPW showed elderly (>= 65 years) HR 2.314, p = 0.001), female gender (HR 0.422, p < 0.001), ECOG PS >= 2 (HR 3.032, p = 0.002), low platelet count (HR 1.757, p = 0.010), and low BTR (<= 4.4) (HR 1.852, p = 0.005) to be significant prognostic factors. Both serum albumin level (r = 0.370, p < 0.001) and ALBI score (r = -0.389, p < 0.001) showed a significant relationship with BTR. Child-Pugh class B, modified ALBI grade (mALBI) 2a, and mALBI 2b predictive values for BTR were 3.589, 4.509, and 4.155 (AUC range: 0.735-0.770), respectively, while the predictive value of ALBI score for low-BTR (<= 4.4) was -2.588 (AUC 0.790).Conclusion ALBI score -2.588 was a predictor for low-BTR (<= 4.4), which was prognostic factors for early HCC patients, and at least patients with mALBI 2b might have an amino acid imbalance.
