Minimal Residual Disease Guiding Adjuvant Therapy in Stage I NSCLC

Официальное название

Minimal Residual Disease (MRD)-Guided Adjuvant Therapy in Stage I Non-Small Cell Lung Cancer: A Prospective, Multicenter, Randomized Controlled Study

Обзор

This investigator-initiated study aims to evaluate the effectiveness of minimal residual disease (MRD) as a biomarker for guiding adjuvant therapy decisions in patients with Stage I non-small-cell lung cancer (NSCLC). The study will compare outcomes between an MRD-guided management group and a standard-of-care group, focusing on whether the use of MRD information can improve the 3-year disease-free survival rate compared to existing treatment protocols. Participants in the MRD-guided management group will receive targeted therapy, immunotherapy, or observation based on their postoperative MRD status, while those in the standard-of-care group will receive treatments or observation according to current clinical guidelines.

• Significant allergies to any targeted drugs, immunotherapies, or chemotherapy agents used in the study.
• Previous use of any traditional Chinese medicine with anti-tumor properties, or use of such medicine within 2 weeks prior to surgery.
