Association of HER2 mutation with immunotherapy outcomes in the pooled immunotherapy cohort. (A) Objective response rate (ORR) and disease control rate (DCR) according to HER2 mutation status and stratified by immune checkpoint inhibitors. Differences between subgroups were compared using the Chi-square or Fisher’s exact tests. (B) Overall survival (OS) according to HER2 mutation status. (C) Hazard ratios of genes with mutations that were significantly associated with OS in univariate Cox models in HER2-mutated tumors. (D) OS according to co-mutations (Co-Mut). Mut: mutation; WT: wild-type. The Cox proportional hazards model was used to evaluate the effects of HER2 mutations or co-mutations on survival.
