Immune checkpoint inhibitor (ICI) combined with chemotherapy is one of the standards of care for advanced non–small cell lung cancer (NSCLC) without driver mutations. However, the biomarker of combination therapy is still unknown. Although previous studies have confirmed that low allele frequency adjusted blood‐based tumor mutational burden (LAF‐bTMB) is associated with the efficacy of ICI monotherapy, there has been no report on the correlation between the efficacy of LAF‐bTMB and ICI combined chemotherapy. This study aimed to explore whether LAF‐bTMB can be used as a predictive biomarker for the efficacy of immunotherapy combined with chemotherapy in advanced NSCLC.
