Abstract Background & Aims Sorafenib is the standard treatment for advanced hepatocellular carcinoma ( HCC ) but is challenging after treatment failure. Appropriate criteria for enrolling patients into second‐line trials are still limited. In this study, we aimed to establish more objective criteria based on Albumin‐Bilirubin ( ALBI ) grade to select patients with better post‐progression survival ( PPS ) for second‐line treatment. Methods Consecutive 404 advanced HCC patients receiving sorafenib were retrospectively enrolled. All patients were in Child‐Pugh class A and BCLC stage C with either portal vein invasion or extrahepatic metastasis at the beginning of sorafenib treatment. Radiological evaluation based on mRECIST criteria and clinical assessments with compliance were performed on schedule. Results During the median follow‐up period of 5.8 months, 310 patients developed progressive disease ( PD ) and 350 deaths occurred. The PD patients were randomized into derivation and validation cohorts by a 1:1 ratio. The independent predictors of poor PPS in derivation cohort were ALBI grade 3 at PD (hazard ratio [ HR ]=3.24, P = .002), new extrahepatic lesions ( NEH ) ( HR =1.75, P = .011), and early PD within 4 months ( HR =1.88, P = .037). ALBI ‐ PD criteria were proposed by incorporating these three risk factors. In the validation cohort, PPS could be independently predicted by presence of early PD , NEH as well as ALBI grade 3 at PD . Patients within ALBI ‐ PD criteria had significant longer median PPS than those beyond it even in Child‐Pugh A (9.7 vs 4.9 months, P = .005) subpopulations. Conclusions The ALBI ‐ PD criteria can differentiate PPS and stratify the patients with advanced HCC for the second‐line trials or salvage therapy.
