Abstract
- Abstract Background and Aim Programmed death 1 (PD‐1) and programmed death ligand 1 (PD‐L1) inhibitors have transformed the treatment landscape of advanced hepatocellular carcinoma (HCC), but consistent responses are not observed in all patients, and prognostic biomarkers to guide treatment decisions are lacking. We aimed to evaluate the predictive value of PD‐L1 expression in advanced HCC patients treated with PD‐1/PD‐L1 inhibitors. Methods A comprehensive search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted. Studies comparing the objective response rate (ORR) and/or disease control rate (DCR) based on the tumor PD‐L1 status of HCC were included. Results Eleven studies with 1,330 HCC patients treated with PD‐1/PD‐L1 inhibitors were included. Pooled odds ratio (OR) analysis demonstrated a significantly improved ORR in PD‐L1‐positive patients compared with PD‐L1‐negative patients (OR, 1.86, 95% CI, 1.35–2.55). Similar results were observed in the anti‐PD‐1 treatment (p
