Patterns of Biomarker Testing Rates and Appropriate Use of Targeted Therapy in the First-Line, Metastatic Non-Small Cell Lung Cancer Treatment Setting.

Despite clear clinical benefit and guideline recommendations for predictive biomarker testing and subsequent first-line targeted therapy treatment in patients with non-small cell lung cancer (NSCLC), there is evidence that testing has not been widely embraced in the clinical setting. This study uses clinical pathways to understand biomarker testing patterns and ensuing first-line treatment decisions. Data of patients with metastatic NSCLC were analyzed for testing rates and treatment selection at 7 cancer programs using data input by providers into the pathways software. Findings were analyzed by type of provider (community or academic). Among providers using clinical pathways, biomarker testing rates were high and appropriate selection of targeted therapy was observed. Clinical pathways can act as a tool to assist oncology practices to promote testing of key biomarkers and subsequent selection of appropriate therapy.
