ROS1 rearrangement has been identified in 1.7% of non small-cell lung cancer (NSCLC) by using a FISH assay. Treatment with ALK/MET tyrosine kinase inhibitors such as crizotinib (Xalkori(R)) has shown early evidence of therapeutic efficacy in ROS1-rearranged NSCLC (Bergethon, et al. J Clin Oncol. 2012;30:863-870).
