BRAF Mutant Lung Cancer: Programmed Death Ligand 1 Expression, Tumor Mutational Burden, Microsatellite Instability Status, and Response to Immune Check-Point Inhibitors

BRAF mutant NSCLC is associated with high level of PD-L1 expression, low/intermediate TMB and microsatellite-stable status. ICPi have favorable activity both in BRAF V600E and BRAF non-V600E mutant NSCLC.
