Abstract
BackgroundThis meta-analysis aimed to assess the performance of the CRAFITY (CRP and AFP in immunotherapy) score as a prognostic factor in hepatocellular carcinoma (HCC) treated with immunotherapy.MethodsThe PubMed, Cochrane Library, and Web of Science databases were searched for published studies. Hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS) and progression-free survival (PFS) outcomes were pooled using fixed- and random-effects models. Odds ratios (ORs) with 95% CI were used to measure the association of individual CRAFITY scores with the disease control rate (DCR).ResultsFour eligible studies comprising 786 patients were included. The results indicate that a lower CRAFITY score is a significant predictor of better OS (HR = 0.22, 95% CI: 0.10–0.50) and PFS (HR = 0.36, 95% CI: 0.23–0.55) outcomes. In addition, the DCR was significantly higher in patients with lower CRAFITY scores (OR = 3.16, 95% CI: 2.00–4.99). A significant positive association between low CRAFITY scores and favorable prognoses was also observed in Barcelona Clinic Liver Cancer stage B/C/D patients.ConclusionIn this study, a low CRAFITY score was associated with better overall outcomes in HCC patients treated with immunotherapy. However, this finding requires further investigation.
