Plasma KRAS mutations and clinical progression of patients surgically treated for PDAC

(a) Kaplan Meier curve of patients with plasma KRAS mutations showed early recurrence (p < .01).(b) Disease-free survival time classified with the frequency of plasma KRAS mutations; No plasma KRAS mutation, once KRAS mutation positive or twice KRAS mutation positive in two tests.(c) Kaplan Meier curve of patients with plasma KRAS mutations showed significantly poor overall survival time after surgical resection (p = .01).
