EGFRm tumors may also overexpress PD-L18

 

For EGFRm NSCLC, PD-L1 expression ranges from 30% to 37%
For EGFRm NSCLC, PD-L1 expression ranges from 30% to 37%

 

~40% of patients with EGFR WT NSCLC may also express PD-L1.8

In newly diagnosed patients with mNSCLC, NCCN Guidelines® recommend PD-1/PD-L1 inhibitor monotherapy or combined with chemotherapy for patients with positive PD-L1 expression (≥50%) and negative or unknown EGFR or ALK mutation status.9,‡

Refer to the NCCN Guidelines for specific treatment recommendations for each setting. Not all agents in a drug class are recommended for all settings.
