[Advances of the Correlation between Driver Gene Status and Immunotherapy ?in Non-small Cell Lung Cancer].

ABSTRACT: In recent years, the checkpoint inhibitors targeted programmed cell death 1 (PD-1) and its ligand 1 (PD-1 ligand, PD-L1) achieved landmark significance in treating a variety of cancers including non-small cell lung cancer (NSCLC). However, current immunotherapy is not precise enough, only 15%-20% of the unselected patients can benefit from the therapy, and there is a possibility of hyperprogression (HP). Therefore, how to select the dominant population is crucial. Although many studies have emphasized the importance of PD-L1 and tumor mutation burden (TMB) and other indicators to guide immunotherapy, current PD-L1 expression level and mutation load cannot be used as a decisive and excluded predictive marker based on various obstacles. With the deepening of research, we found that there is a close relationship between lung cancer-driver gene mutation and aberrant activation of PD-1/PD-L1 signal pathways, and the correlation between gene mutation and immunotherapy efficacy has broad research value. This article will revolve around the above issues.?.

Project description:BackgroundMolecular testing for alterations in oncogenic driver genes and targeted therapies have become standard procedures for non-small cell lung cancer (NSCLC) patients. However, little evidence has shed light on the pattern of co-existence of driver genes in NSCLC, and whether they may have different tumor features affecting immunotherapy is still unclarified.MethodsGenomic alterations in 14 lung cancer-related genes were conducted in 3440 Chinese NSCLC patients using next-generation sequencing. Meanwhile, tumor mutational burden and immunotherapy dataset from the Memorial sloan kettering cancer center (MSKCC) and lung adenocarcinoma dataset from The Cancer Genome Atlas (TCGA) were utilized for analyzing the impact of the co-occurring alterations on patients' survival following immunotherapy.ResultsIn this cohort, 90.17% of patients had at least one somatic alteration in the 14 genes, including 51% of co-occurring alterations. TP53 and epidermal growth factor receptor (EGFR) were the most prevalent genes (54.74% and 53.55%, respectively), followed by KRAS, ERBB2, ALK, PIK3CA, ROS1, RET, MET, BRAF, KIT, FGFR1, PDGFRA, and NRAS. The prevalence of TP53, EGFR, and ERBB2 in our cohort were significantly higher than that from the TCGA database, whereas KRAS, BRAF, and PDGFRA were significantly lower than the latter. Furthermore, the patients who harbored multiple alterations (8.86%, 31/350) in eight driver genes survived longer and have a higher tumor mutation burden compared to the patients with a single alteration. Similar result was found between the patients with co-occurring alteration of EGFR and other driver genes and the patients with single EGFR alteration. Meanwhile, we found a distinct immune cell infiltration feature between patients with single and multiple driver gene alterations, as well as between patients with only EGFR alteration and co-occurring groups.ConclusionThis study identified a unique driver gene feature and found patients harboring co-occurring alterations of EGFR and other driver genes may benefit from immunotherapy, which may provide more therapeutic selections for EGFR-mutated NSCLC patients and merit additional investigation.
