Overview
Brief Summary
The goal of this observational study is to explore whether ctDNA-MRD dynamic monitoring can more effectively predict the therapeutic effect of induction chemoimmunotherapy followed by surgery or non-surgical treatment for stage IIIB-C driver-negative NSCLC in the MDT model, so as to accurately guide clinical diagnosis and treatment.
Detailed Description
This study is a single-center, observational, non-interventional, prospective study. 50 patients diagnosed with stage IIIB-C driver-negative NSCLC receiving induction chemoimmunotherapy will be planned to be enrolled in the study. Pre-treatment biopsy tissues of enrolled patients will be collected for next-generation sequencing (NGS) of institutionally-developed 1021-gene panel, and personalized detection panel will be customized based on NGS testing results. Patients will be received induction chemoimmunotherapy followed by surgery or non-surgical treatment in the MDT model and ctDNA-MRD testing will be performed at prespecified time points. For patients who received surgery following induction therapy, peripheral blood will be collected in baseline, 1 day before the third cycle of neoadjuvant therapy, 1 day before surgery, 3 days after surgery and landmark time and pulmonary venous blood will be collected intraoperatively. For patients who received non-surgical treatment following induction therapy, peripheral blood will be collected in baseline, 1 day before the third cycle of neoadjuvant therapy, 1 day before non-surgical therapy and landmark time. All included patients will be regularly followed up for at least 5 years.
