Propensity score analysis of overall survival between first- and second-generation EGFR-TKIs using real-world data.

ABSTRACT: We constructed a data set of EGFR-mutant non-small-cell lung carcinoma (NSCLC) patients, and compared the overall survival of first-generation (1G), and second-generation (2G) EGFR-tyrosine kinase inhibitors (TKIs) in clinical practice using a propensity score. We reviewed the clinical data of consecutive EGFR-mutated NSCLC patients who received EGFR-TKI therapy between January 2008 and August 2017 at 11 institutions in Japan. The primary endpoint was overall survival (OS). When comparing OS between 1G and 2G EGFR-TKIs, propensity score analyses were performed using 2 methods: matching and inverse probability of treatment weighting (IPTW). (Clinical Trial information: UMIN000030121) In total, 1400 patients from 11 institutions were enrolled in this study, and the data from the 1366 patient
