Fig. 4From: Anti-PD-1 antibody in combination with radiotherapy as first-line therapy for unresectable intrahepatic cholangiocarcinomaPatient survival in relation to TMB, PD-L1, or microsatellite status and genetic alterations. Kaplan-Meier plots of median (A) PFS and (B) OS of TMB high versus TMB low patients. Median (C) PFS and (D) OS of PD-L1 positive versus PD-L1 negative patients. Median (E) PFS and (F) OS of MSI versus MSS patients. MSI, microsatellite instability; MSS, microsatellite stability; PD-L1, programmed death-ligand 1; TMB, tumor mutational burdenBack to article page
