Combining ctDNA KRAS mutations with protein biomarkers increases sensitivity for early detection of PDAC. (A) Sensitivities of ctDNA KRAS mutations alone, ctDNA KRAS mutations plus CA19-9, and ctDNA KRAS mutations with CA19-9 and other proteins (combination assay) with respect to AJCC stage. (B) Sensitivities of ctDNA KRAS mutations alone, ctDNA KRAS mutations plus CA19-9, and ctDNA KRAS mutations with CA19-9 and other proteins (combination assay) with respect to tumor size. Error bars represent 95% CIs.
