Herein we identified a KRAS Q22K mutation and frameshift mutations in the genes encoding serine/threonine kinase 11 (STK11) and ataxia telangiectasia mutated serine/threonine kinase (ATM) by next-generation sequencing in a patient with ALK rearrangement-positive oligo-metastatic NSCLC, whose disease progressed while on two ALK-targeted therapies.
