ReviewTargeted therapies in non-small cell lung cancer: a focus on ALK/ROS1 tyrosine kinase inhibitors.
Anaplastic lymphoma kinase (ALK) and ROS1 rearrangements define important molecular subgroups of advanced non-small cell lung cancer (NSCLC). The identification of these genetic driver alterations created new potential for highly active therapeutic interventions. After discovery of ALK rearrangements in NSCLC, it was recognized that these confer sensitivity to ALK inhibition. ⋯ Regarding ROS1 rearrangement, to date crizotinib is the only ALK-tyrosine kinase inhibitor receiving indication as treatment of ROS1 positive advanced NSCLC. Expert commentary: Although novel ALK-inhibitors are under clinical investigation compared to crizotinib as front-line treatment for ALK-positive NSCLC, nowadays the current standard first-line therapy for these patients is crizotinib. Further research will clarify the best management of ALK-positive NSCLC, above all who progress on first-line crizotinib.
