The Predictive Biomarkers in Patients With Locally Advanced Non-small Cell Lung Cancer

Summary

This study is a prospective cohort study to evaluate the peripheral blood lymphocyte subsets as predicative biomarkers reflecting the efficacy and toxicity in patients with locally advanced non-small cell lung cancer (NSCLC) received chemoradiotherapy (CRT) with or without immune checkpoint inhibitors (ICIs).
