Association of anaplastic lymphoma kinase variants and alterations with ensartinib response duration in non-small cell lung cancer

Here, we aimed to assess the association of ALK variants and alterations with ensartinib response duration in NSCLC, and explore the potential value of computed tomography (CT) radiomic features in predicting progression-free survival (PFS). We enrolled 88 patients with identified ALK variant NSCLC in a multicenter phase 2 trial, and assessed the impact of ALK variants and secondary ALK alterations on the clinical outcome (response duration) of patients receiving ensartinib. Our study showed that secondary ALK alterations were adversely associated with ensartinib efficacy, and that ALK variants might not correlate with PFS. The quantitative radiomic signature provided added prognostic prediction value to the clinicopathological features. READ ARTICLE

Development of complex renal cysts: A complication associated with Crizotinib therapy

Crizotinib is a tyrosine kinase inhibitor that has been found to be effective in the treatment of anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer. This targeted cancer therapy agent has been shown to have superior efficacy over standard chemotherapy in this small subset of lung cancer patients. An adverse effect of this drug therapy is the development of complex renal cysts. Here, we present a case of a 68-year-old patient with non-small cell lung cancer on Crizotinib therapy who developed complex bilateral renal cysts. It is important to recognize this drug-related complication in order to avoid mistaking it for disease progression, primary renal malignancy, or renal infection. READ ARTICLE
