Kaplan-Meier survival analysis and log-rank analysis of patients with or without ALK rearrangements. Patients with ALK rearrangement had a better prognosis than did those without ALK rearrangement, though no statistically significant difference in survival (log-rank test, P = 0.110) was observed due to the small cohort. One patient who did not undergo targeted therapy for ALK rearrangement died. To some extent, ALK inhibitors are effective for these patients
