Description
KRAS G12/G13 status was evaluated in cell-free DNA (cfDNA) of patients with untreated metastatic adenocarcinoma of the pancreas that were randomised (1:1) to receive gemcitabine plus trametinib or placebo. KRAS mutations were identified in 103 patients using cfDNA. There was no difference betweeen overall survival of KRAS Mutation-positive and -negative patients. Of note, evaluation of KRAS mutations from archival tissue from 71/143 patients identified 8 patients with mutant KRAS (wildtype by cfDNA) and 3 patients with wildtype KRAS (mutant by cfDNA).
