RECIST progression patterns during EGFR tyrosine kinase inhibitor treatment of advanced non-small cell lung cancer patients harboring an EGFR mutation

摘要

Background: Progression patterns at the response evaluation criteria in solid tumors-progressive disease (RECIST-PD) during treatment with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) for advanced non-small cell lung cancer (NSCLC) in patients harboring an EGFR mutation are clinically heterogeneous. We evaluated the association between progression patterns during EGFR-TKI treatment and prognosis after treatment in such patients.
