Ten patients with ALK-rearranged NSCLC were included: five who developed rapid resistance to crizotinib (progression-free survival (PFS) ≤ 3 months) and five who exhibited a good response to crizotinib (PFS ≥ 36 months)....Patients with a poor response to crizotinib harbored a greater burden of somatic mutations than those with a good response...Compared with the patients carrying wild-type TP53 or TP53 exon 3 deletion, 29 patients with TP53 G245S mutation showed a shorter survival time (P < 0.05)...
