Mechanism of Response to IMFINZI Neoadjuvant Therapy in Non-small Cell Lung Cancer Patients Based on Multiple-omics Models

To explore the safety and immunobiological effects of 2 cycles of duvalumab combined with albumin paclitaxel + cisplatin/carboplatin for patients with stage IB-IIIA non-small cell lung cancer; use whole exome sequencing , GEP gene expression profile detection based on NanoString platform and other methods to predict the efficacy of IMFINZI neoadjuvant therapy, looking for potential biomarkers; study the impact of neoadjuvant therapy of I drug on the tumor microenvironment at multiple levels such as genome, transcriptome, PD-1/PD-L1 protein transcription and expression, T cell TCR immune groupthe library and T cell subsets, and provide comprehensive exploratory research evidence for finding the biomarker for the neoadjuvant anti-PD-L1 therapy of lung cancer .
