Immunotherapy for metastatic non–small cell lung cancer: Is it really a no‐brainer?

Abstract

There is still much progress to be made in understanding the underlying mechanisms of brain metastasis development and its optimal therapy in non–small cell lung cancer (NSCLC); it is very important to expand research in this area because brain metastasis strongly affects patients' quality of life and overall survival. This editorial reviews the available data in the context of a recent meta‐analysis of the pivotal IMpower130, IMpower131, and IMpower150 studies, which explores metastatic epidermal growth factor receptor and anaplastic lymphoma kinase wild‐type NSCLC to determine potential preventative factors and risk factors for the development of brain metastasis, specifically the question of whether immunotherapy (the anti–programmed death ligand 1 antibody, atezolizumab in particular) plays a role in preventing brain metastasis.
