Real-World Concordance Of Clinical Practice With Asco And Nccn Guidelines For Egfr/Alk Testing In Ansclc.

212Background: Timely and appropriate biomarker testing guides evidence-based treatment decision-making in advanced non-small cell lung cancer (aNSCLC). American Society of Clinical Oncology (ASCO) and National Comprehensive Cancer Network (NCCN) guidelines recommend that all treatment-eligible patients with non-squamous, or squamous histology in non-smokers undergo EGFR and ALK biomarker testing prior to initiating first line therapy. Genentech’s Learning and Clinical Integration team and Flatiron Health explored the frequency of EGFR/ALK testing and overall time between advanced disease diagnosis, results receipt and treatment initiation in clinical oncology practices. Methods: Structured and unstructured data were obtained from Flatiron’s electronic health record database. 6,991 patients from 166 clinics diagnosed after 1/1/14 with at least 2 visits before 8/31/15 were randomly selected from the Flatiron aNSCLC national cohort of u003e 25,000 patients. Dates of specimen collection, results receipt and trea...
