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 .
A single-center prospective exploratory single-arm neoadjuvant therapy study, based on a prospective cohort study, according to patients' blood and tumor samples before and after neoadjuvant treatment, WES, GEP gene expression profiling, TCR sequencing and ctDNA dynamic monitoring were used to explore the intratumoral immune consequences of PD-1 monoclonal antibody administration and identify potential Response biomarker.
