This study aims to explore the efficacy and safety of Erlotinib/Gefitinib combined with bevacizumab in the real world for advanced non-squamous cell lung cancer with EGFR mutation, explore new drug resistance mechanisms under the A+T regimen and consistency between plasma and tissue detection driving genes, and finally assess the predictive value of plasma dynamic detection driving gene mutation profiles in predicting disease. The role of disease progression risk.


A retrospective study of 30 cases of advanced non-squamous non-small cell lung cancer (NSCLC) with EGFR mutation positive treated with A+T was conducted to observe the efficacy and safety of A+T 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 tissue gene test (NGS) and plasma gene test (NGS) at the progression of A + T treatment; 3. New drug resistance mechanism of A + T treatment; 4. Plasma dynamics during A + T treatment. Detection (the first efficacy evaluation and a blood sampling before imaging PD) exploration and imaging progress sequence; 5. Plasma large panel dynamic drive gene mutation spectrum analysis to build disease progression risk model.
