Clinical Trial Summary

The goal of this observational study is to explore whether ctDNA dynamic monitoring plus AI-based pathology can more effectively predict the therapeutic effect of neoadjuvant chemoimmunotherapy for resectable lung squamous cell carcinoma, so as to accurately guide clinical diagnosis and treatment.

Description:

This study is a single-center, observational, non-interventional, prospective study. 50 patients diagnosed with lung squamous cell carcinoma receiving neoadjuvant chemoimmunotherapy (ranging 2 to 4 cycles) will be planned to be enrolled in the study. Pre-treatment biopsy tissues of enrolled patients will be collected for whole exon sequencing (WES) testing, and personalized detection panel will be customized based on WES testing results. Peripheral blood will be collected 1 day before each cycle of neoadjuvant therapy, 1 day before surgery, 3 days after surgery, and 3 weeks after surgery for ctDNA testing. In addition, the prediction model of AI-based pathology will be constructed by AI deep learning based on pathological sections of pre-treatment biopsy tissues. All inclued patients will be regularly followed up for at least 5 years.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pathologic completet response (pCR) rate	pCR rate is defined as the percentage of participants having an absence of residual tumor cells in resected lung specimens and lymph nodes following completion of neoadjuvant therapy.	Up to 1 year
Primary	ctDNA resolution	ctDNA resolution is defined as the change or resolution in tumor-derived DNA found in the bloodstream from diagnosis to after neoadjuvant therapy and after surgery, correlated with pathologic complete response (pCR)	Up to 2 years
Primary	Development of computer algorithm to identify pCR features	Development of computer algorithm to identify pCR features	From retrospective data collection to algorithm development (6 month)
Primary	Validation of computer algorithm to identify pCR features	Validation of computer algorithm to identify pCR features	From prospective data collection to algorithm validation (6 months)
Secondary	Major pathological response (MPR) rate	MPR rate is defined as the percentage of participants having =10% viable tumor cells in the resected primary tumor and resected lymph nodes following completion of neoadjuvant therapy.	Up to 1 year
