ALK and non-small cell lung carcinoma: Four studies with 293 patients investigated the impact of TP53 mutational status on outcome of patients with activating ALK rearrangements (mainly EML4-ALK fusions) receiving ALK-TKIs therapy (first generation ALK-TKIs----crizotinib; next generation ALK-TKIs---ceritinib, alectinib, brigatinib, ect), percent of TP53 concurrent mutations in ALK-rearranged advanced NSCLC in these four studies ranged from 23.44–60%.
