Analysis of Deoxyribonucleic Acid and Ribonucleic Acid Next-Generation Sequencing in Non-Small Cell Lung Cancer Patients Without Pathological Complete Response Following Neoadjuvant Immunotherapy

Sponsor: Tianjin Medical University Cancer Institute and Hospital

Summary

This multicenter, retrospective cohort study plans to enroll patients with lung adenocarcinoma who received neoadjuvant immunotherapy prior to surgery and did not achieve pathological complete response (non-pCR) upon postoperative pathological evaluation. Using Deoxyribonucleic Acid(DNA) and Ribonucleic Acid(RNA) next-generation sequencing (NGS), the investigators aim to detect driver genetic alterations to investigate the real-world frequency of driver gene positivity in postoperative samples from patients with lung adenocarcinoma-whose EGFR and ALK status had been previously excluded via pathological complete response(pCR) or DNA-based next-generation sequencing-yet still did not attain pathological complete response(pCR) after neoadjuvant immunotherapy. Additionally, the study will characterize the driver-positive patient subgroup and compare the efficacy of postoperative adjuvant immunotherapy between driver-positive and driver-negative populations.
