Conclusions: Brain, liver and bone metastases are lower in ALKþpatients with Ple-I/E. Presentation with Ple-I/E in patients with ALKþ NSCLC is associated with longer overall and progression-free survival. Background: ALK mutation occurs in approximately 3-5% of patients with NSCLC. At the baseline, Ple-I/E are more frequent in ALKþ patients with NSCLC. In the study, we aimed to evaluate characteristics of ALKþpatients who have Ple-I/E. Methods: In this multicenter study, patients with ALKþ NSCLC who have Ple-I/E were retrospectively analyzed. Clinical and demographic characteristics of the disease, response rates, median PFS and OS were evaluated in 362 ALKþpatients with NSCLC. Results: Of the patients, 198 (54.7%) were male. The median age at the time of diagnosis was 54 (21-85) years. The median age was higher in male (57 vs 52 years; p¼0.011). The most common histology was adenocarcinoma (100%). At the baseline, 57 (15.7%) patients had Ple-I/E. The median age of patients with Ple-I/..... READ ARTICLE
