Targeting CNS Metastases in Non–Small Cell Lung Cancer With Evolving Approaches Using Molecular Markers

With multiple generations of targeted therapies now available, the treatment for CNS metastases should be tailored to the patients with consideration given to molecular testing results, CNS penetrance of systemic therapy, patient characteristics, and multidisciplinary review. More research is needed in understanding the clonal evolution of CNS metastases, and the development of novel therapeutics with CNS efficacy.
