    Molecular resistance mechanisms of ALK inhibitors and implications for therapeutic management of ALK-rearranged lung cancer patients

    Excerpt:
    In this study crizotinib resistance mutations were confirmed in 11 (20%, N=51) specimens from biopsy sites that included pleural fluid (31%), liver (22%), and nodal tissue (18%) from 10 patients….Other mutations (frequency) detected were C1156Y (2%), G1202R (2%), I1171T (2%), S1206Y (2%), and E1210K (2%).
