Brief Summary

Immunotherapy for PD-L1 positive patients is still ineffective in some patients,which may be related to the complex immune microenvironment.In view of this bottleneck, further refinement of immunotyping and in-depth study of drug resistance mechanism are the most important tasks. In this observational study, we evaluated the difference of gene mutation and immune microenvironment and therapeutic effect in primary NSCLC.
