Efficacy and Safety of ALK Tyrosine Kinase Inhibitors in Elderly Patients with Advanced ALK-Positive Non-Small Cell Lung Cancer: Findings from the Real-Life Cohort.

Background: Little is known regarding the anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) efficacy and safety in the elderly.

Objectives And Methods: Consecutive patients (n = 53) with ALK-positive advanced non-small cell lung cancer treated with an ALK TKI were identified through internal databases of three cancer centers and divided into groups A (< 65 years old; n = 34) and B (≥65 years old; n = 19). Progression-free survival (PFS), ALK TKI safety and overall survival (OS) were assessed.
