Funding represents a decisive barrier to the nationwide implementation of genetic testing for a key lung cancer mutation in Canada, a recent study finds. Patients with non-small cell lung cancer (NSCLC) who have a mutation in the EGFR gene frequently benefit from treatment with EGFR inhibitors. AstraZeneca, makers of the EGFR inhibitor gefinitinb (Iressa), reimbursed Canadian laboratories for offering EGFR mutation testing to patients with advanced non-squamous NSCLC for 12 months. EGFR mutation testing was rapidly adopted into routine clinical practice in Canada. However, testing rates dropped sharply once the reimbursement program ended. Researchers conclude that a national strategy is needed to provide resources for continued EGFR testing.
