Prognostic analysis of clinicopathological factors for overall survival in PDCRC. a Kaplan-Meier survival analysis of N0 and N1 + N2 patients. The patients with N stage(+) tended to have a poor prognosis (P < 0.001). b Kaplan-Meier survival analysis of TNM stage I, II, and III patients. The patients with advanced TNM stage tended to have a poor prognosis (P < 0.001). c Kaplan-Meier survival analysis of NED(−) and NED(+) patients. The patients with NED(+) tended to have a poor prognosis (P = 0.003)
