BACKGROUND:: Patients with hepatocellular carcinoma (HCC) and with a single tumor <2 cm in size are classified as having Barcelona Clinic Liver Cancer (BCLC) stage 0 HCC. We aimed to investigate the role of the albumin–bilirubin (ALBI) grade in predicting outcomes in patients with BCLC stage 0 HCC. METHODS:: We retrospectively enrolled patients with BCLC stage 0 HCC in Taipei Veterans General Hospital from 2007 to 2015. Prognostic factors were analyzed using a Cox proportional hazards model and propensity score matching (PSM) analysis. RESULTS:: There were 420 patients enrolled, including 207 with ALBI grade 1, and 213 with ALBI grade 2 or 3. After a median follow-up of 60.0 months (interquartile range, 37.2–84.6 months), 179 patients died. The cumulative 5-year overall survival (OS) rates were 80.6% in patients with ALBI grade 1 and 53.7% in those with ALBI grade 2 or 3, respectively (p <0.001). Multivariate analysis showed that age >65 years, negative hepatitis B surface in serum, creatinine >1.0 mg/dL, platelet count ≤10/mm, tumor size >1.5 cm, non-surgical resection (SR) therapy, and higher ALBI grade were independent risk factors related to poor OS. Patients who underwent SR had a better OS and recurrence-free survival than those who received radiofrequency ablation, which was confirmed by a multivariate analysis and PSM analysis. CONCLUSION:: The ALBI grade can determine OS for patients with BCLC stage 0 HCC. SR can also provide a better outcome than non-surgical treatment.
