To estimate parameters associated with treatment patterns and related clinical outcomes.Including physician reported PFS and OS.
The objectives of this study are to assess molecular testing, treatment patterns, and associated clinical outcomes among patients with epidermal growth factor receptor (EGFR) mutation-positive locally advanced or metastatic non-small cell lung cancer (NSCLC) who have progressed from first-line EGFR-TKI (tyrosine kinase inhibitor) therapy. This study is descriptive in nature and does not attempt to test any specific a priori hypotheses
