PIMSH13 – Oncology: Mutation Testing for Stage IV Lung Cancer Completed Prior to the Start of Targeted Therapy


Measure Title: Oncology: Mutation Testing for Stage IV Lung Cancer Completed Prior to the Start of Targeted Therapy

Measure Description Proportion of stage IV nsNSCLC patients tested for actionable biomarkers and received targeted therapy or chemotherapy based on biomarker results

Denominator: Patients with stage IV non-squamous, NSCLC receiving initial treatment during the measurement period AND patient encounter during the performance period

Clinical Recommendation Statement: This measure is endorsed by The US Oncology Network Steering Committee. Recent discovery of some of the driver mutations for NSCLC have advanced more individualized and targeted treatment options. It is now a standard recommendation that patients with advanced NSCLC undergo routine molecular testing to identify certain abnormalities which influence treatment selection to improve efficacy. Guidelines:
NCCN Practice Guidelines in Oncology. Non-Small Cell Lung Cancer. Published July 14, 2017.
2017 CAP/IASLC/AMP guideline recommendations for biomarker testing in NSCLC. Lindeman NI, Cagle PT, Beasley MB, et al. Molecular testing guideline for selection of lung cancer patients for EGFR and ALK tyrosine kinase inhibitors: guideline from the College of American Pathologists, International Association for the Study of Lung Cancer, and Association for Molecular Pathology. J Mol Diagn. 2013;15(4):415-453. ‘NCCN Clinical Practice Guidelines in Oncology. Non-small cell lung cancer (2015).
ASCO provisional clinical opinion: Epidermal growth factor receptor (EGFR) mutation testing for patients with advanced non-small-cell lung cancer considering first-line EGFR tyrosine kinase inhibitor therapy. (2011)

Measure Rationale: Clinicians still face considerable challenges when establishing and implementing biomarker testing standards, including interpreting large-scale genomic data from multiple tumor types, making it difficult to stay current with practice standards. A recent study of oncologists assessed the degree to which a patient with NSCLC’s genetic makeup impacted first-line treatment decisions. 60% of oncologists in the US did not base their treatment decisions on a patient’s genetic mutation subtype. Despite ordering mutation tests, 21% determined the treatment regimen for their patients before the mutation test results were available. Overall, 23% of clinicians did not consider EGFR mutation subtypes in making treatment decisions. (Spicer, 2015) Monitoring of appropriate biomarker testing through quality measurement and providing that feedback to physicians is a first step to understanding clinical practice guideline compliance to optimize diagnosis and management of NSCLC.
