About

This study was designed to explore the efficacy and safety of Crizotinib as a first-line treatment for advanced NSCLC with ROS1 rearrangement positive mutation in the real world, explore the new drug resistance mechanism of ROS1 under Crizotinib treatment and the consistency of plasma and tissue detection driving genes, and finally evaluate the mutation spectrum of plasma dynamic detection driving genes. In predicting the risk of disease progression.

Full description

This is a research project involving patients in Medical Oncology Department of Affiliated Cancer Hospital of Xiangya School of Medicine Central South University. Retrospective study of 40 patients with advanced non-squamous non-small cell lung cancer (NSCLC) using Crizotinib ROS1 rearrangement positive mutation was conducted to observe the efficacy and safety of Crizotinib regimen in the real world.Exploratory research contents are as follows: 1. Consistency between tissue gene test (NGS) and plasma gene test (NGS) at the initial diagnosis; 2. Consistency between NGS and plasma gene test (NGS) at the progression of clozotinib treatment; 3. Drug resistance mechanism of clozotinib in ROS1 rearrangement positive NSCLC; 4. Plasma drug resistance. Large panel dynamic driven gene mutation analysis was used to construct disease progression risk model.
