Brief summary
The purpose of this project is to conduct an observational study on the efficacy and safety of entrectinib in real-world patients with ROS1-positive NSCLC who have received entrectinib treatment, while exploring the mechanism of entrectinib's brain protection and resistance mechanism. Because this study is a non-interventional study, it will not interfere with your usual treatment. However, your medical data will be analyzed, and the results will help improve future treatment options for ROS1 positive NSCLC patients and improve their quality of life.This study was divided into three cohorts. Cohort 1: For patients with advanced ROS1-positive NSCLC who met the inclusion criteria and had not received TKI treatment, they were treated with entrectinib until disease progression or intolerance (N=15); Cohort 2: For patients with advanced ROS1-positive NSCLC who met the inclusion criteria and had received first-generation ROS1 TKI treatment with disease progression on crizotinib, they were treated with entrectinib until disease progression or intolerance (N=15); Cohort 3: For patients with ROS1-positive NSCLC who had failed multiple lines of treatment, they were treated with entrectinib until disease progression or intolerance (N=10). Regular follow-up was conducted and relevant clinical data were recorded, followed by Cox regression analysis and survival analysis. The information that needs to be recorded includes baseline and treatment genetic testing, demographic information, anti-cancer history, and concomitant medication use, as well as the use of study drugs and adverse events during treatment visits, survival and subsequent drug use after discharge, and the follow-up frequency consistent with clinical practice. Subjects are eligible for a complimentary NGS test upon the development of entrectinib resistance.
