Non–Small Cell Lung Cancer: Recommendations for Biomarker Testing and Treatment

Abstract

Updates to the NCCN Guidelines for Non–Small Cell Lung Cancer (NSCLC) for 2021 include recommendations for biomarker testing in all appropriate patients with newly diagnosed advanced lung cancer, including squamous cell lung cancer. When a targetable genetic alteration is detected, the NCCN Guidelines recommend treatment with a first-line therapy targeted to that alteration. The guidelines contain new information on use of adjuvant treatment with osimertinib for resected early-stage EGFR-mutated NSCLC. New targeted agents are now recommended for the treatment of ALK rearrangements, RET alterations, MET exon 14 skipping mutations in patients with advanced NSCLC; and new immunotherapy agents are recommended for advanced NSCLC without a driver oncogene.
