Treatment patterns and outcomes in patients with non-squamous advanced non-small cell lung cancer receiving second-line treatment in a community-based oncology network

This retrospective observational study provides new insights into treatment patterns, biomarker testing, and outcomes in advanced NSCLC within the context of a large community oncology network. Outcomes of these community practice patients, although poor, were similar to those reported in 2nd-line clinical trials for relevant regimens. EGFR testing in community practice rose rapidly after 2010.
