Abstract B31: Single-agent pemetrexed in patients with ALK-positive NSCLC: A retrospective analysis of investigator-reported outcomes

Experience in Integrating <i>ALK</i> Testing and Crizotinib into the Routine Treatment of Patients with Non-Small Cell Lung Cancer

<b><i>Background: </i></b>Crizotinib, an inhibitor of the anaplastic lymphoma kinase (ALK), is approved since 2012 in Switzerland for use in <i>ALK</i>-rearranged advanced pretreated non-small cell lung cancer (NSCLC). <b><i>Patients and Methods: </i></b>Here we describe our own experience with crizotinib and <i>ALK </i>testing via fluorescence in-situ hybridization (FISH) in the first 10 <i>ALK</i>-positive patients who were treated in central Switzerland in 2011 on a compassionate use basis. <b><i>Results: </i></b>We have demonstrated that FISH testing for <i>ALK </i>can be performed simultaneously with other diagnostic procedures, providing oncologists with results in a timely manner to make informed decisions about patient treatment. The majority of our patients treated with crizotinib had a clinical benefit, and the drug was tolerated well. <b><i>Conclusion: </i></b>The clinical development of crizotinib has been extremely rapid. Nonetheless, by the time crizotinib was approved, many centers including our own had local testing in place and clinical experience with the drug. This emphasizes the importance of broad clinical studies and compassionate use programs in oncology.
