Aim: Osimertinib is a key drug for EGFR mutation-positive non-small-cell lung cancer (NSCLC). As the hazards ratio of overall survival in comparison with first-generation EGFR-tyrosine kinase inhibitors was almost similar between FLAURA and ARCHER 1050, salvage use of osimertinib is still a treatment option. Patients & methods: We retrospectively analyzed the clinical courses of EGFR mutation-positive NSCLC patients who were potential candidates for salvage osimertinib. Results: Among 524 patients enrolled from five hospitals, 302 patients underwent biopsy, with 52.6% detection rate of T790M. Osimertinib was administered in 93.6% of the T790M-positive patients. The overall response rate and median progression-free survival time of osimertinib were calculated with 147 patients, to be 55.6% and 17.2 months, respectively. Conclusion: Osimertinib is active for T790M-driven acquired resistance in EGFR-mutant NSCLC, but the detection of T790M was unsatisfactory.
