    Abstract:
    AIMS: Non-small cell lung cancer (NSCLC) patients with EGFR mutations do not respond well to checkpoint inhibitors. However, little is known about the activity of immunotherapy in NSCLC with other driver mutations. The increasing use of next-generation sequencing (NGS) leads to molecular findings that face the clinician with problems while choosing the best treatment. This study aims at analyzing response of NSCLC with driver mutations to immunotherapy. PATIENTS AND METHODS: We retrospectively included 84 NSCLC patients diagnosed and treated at 2 German tertiary-care lung cancer centers using NGS and treatment with immunotherapy. Response to immunotherapy was analyzed in correlation to molecular findings. RESULTS: 51 patients harbored at least 1 driver mutation. PIK3CA, EGFR, and STK11 mutations did not respond to immunotherapy. KRAS, TP53, and MET exon 14 skipping mutations responded well. One patient with NF-1 mutation showed durable response. CONCLUSIONS: Molecular testing may be of use in guiding treatment decision making in NSCLC.
