Prospect of immunotherapy alone in patients with advanced NSCLC with high btmb: a review and a meta-analysis

Lung cancer is the most prevalent cancer in the world, and the main treatment for advanced non-small cell lung cancer is immunotherapy combined with chemotherapy. In recent years, bTMB has received increasing attention as an emerging metric for monitoring the efficacy of tumour immunotherapy in terms of its operability, accessibility and real-time nature. We envisaged whether immunotherapy alone could be used to reduce the side effects of chemotherapy in patients with high bTMB lung cancer. We thus did a meta-analysis in order to show that immunotherapy alone is feasible in patients with high bTMB NSCLC.
