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. .
Insights
Checkpoint inhibitors targeting programmed cell death 1 (PD-1) and PD-1 ligand (PD-L1) show promise for cancer treatment. Research indicates a link between lung cancer-driver gene mutations and PD-1/PD-L1 pathway activation, suggesting potential for improved immunotherapy selection.
Area of Science:
- Oncology
- Immunotherapy
- Genetics
Background:
- Programmed cell death 1 (PD-1) and its ligand (PD-L1) checkpoint inhibitors have advanced cancer treatment, including non-small cell lung cancer (NSCLC).
- Current immunotherapies lack precision, benefiting only 15-20% of patients and risking hyperprogression (HP).
- Predictive markers like PD-L1 expression and tumor mutation burden (TMB) have limitations for guiding treatment decisions.
Purpose of the Study:
- To explore the relationship between lung cancer-driver gene mutations and the PD-1/PD-L1 signaling pathway.
- To investigate the potential of gene mutations as predictive markers for immunotherapy efficacy in NSCLC.
- To address the need for more precise patient selection for cancer immunotherapy.
Main Methods:
- Literature review focusing on studies investigating PD-1/PD-L1 pathway, TMB, and gene mutations in NSCLC.
- Analysis of existing data correlating specific lung cancer-driver gene mutations with immunotherapy response.
- Exploration of the mechanistic links between gene mutations and aberrant PD-1/PD-L1 activation.
Main Results:
- Evidence suggests a significant correlation between specific lung cancer-driver gene mutations and the aberrant activation of the PD-1/PD-L1 signaling pathway.
- Gene mutations may play a crucial role in modulating the tumor microenvironment and response to immunotherapy.
- The limitations of current predictive markers highlight the need for novel biomarkers.
Conclusions:
- Lung cancer-driver gene mutations represent a promising area for identifying patients who will benefit from PD-1/PD-L1 targeted immunotherapy.
- Further research into the correlation between gene mutations and immunotherapy efficacy is warranted for improved patient stratification.
- Understanding these genetic links could lead to more personalized and effective cancer treatment strategies.
