Recent studies have focused on understanding the mechanisms of resistance to immunotherapy in non-small cell lung cancer (NSCLC). One study utilized multi-omic profiling to analyze the tumor microenvironment (TME) of NSCLC patients, revealing that interactions between tumor cells and macrophages promote collagen deposition, which obstructs T cell infiltration and correlates with poor prognosis (ref: Yan doi.org/10.1038/s41588-024-01998-y/). Another significant finding was the identification of the miR-23a/27a/24-2 cluster, which was shown to drive immune evasion and resistance to PD-1/PD-L1 blockade, highlighting the role of Wnt/β-catenin signaling in maintaining its expression (ref: Luo doi.org/10.1186/s12943-024-02201-w/). Furthermore, a study on CXCR1 revealed its enrichment in resistant samples from patients treated with third-generation EGFR-TKIs, suggesting its potential as a predictive biomarker for resistance (ref: Wang doi.org/10.1038/s41392-024-02045-2/). In clinical trials, the combination of toripalimab with chemotherapy demonstrated improved overall survival (OS) compared to chemotherapy alone, with a median OS of 23.8 months versus 17.0 months (ref: Zhong doi.org/10.1038/s41392-024-02087-6/). Additionally, a deep learning model was developed to predict immunotherapy responses in advanced NSCLC, achieving an overall response rate (ORR) of 26% in the developmental cohort (ref: Rakaee doi.org/10.1001/jamaoncol.2024.5356/). These findings underscore the complexity of resistance mechanisms and the need for personalized approaches in immunotherapy for NSCLC.
