Recurrence scoring system predicting early recurrence for patients with pancreatic ductal adenocarcinoma undergoing pancreatectomy and portomesenteric vein resection

Figure 5 Survival analysis of recurrence nomogram score and clinicopathological variables in the training cohort. A and B: Kaplan-Meier survival plots for patients in the high-risk [recurrence nomogram score (RNS) > 4.23] and low-risk (RNS ≤ 4.23) groups. The high-risk group showed significantly poorer recurrence free survival (RFS) and overall survival (OS) compared with the low-risk group; C-F: Patients with portomesenteric vein invasion showed poorer RFS and OS than those without (C and E), and patients with pain showed poorer RFS and OS than those without (D and F). RNS: Recurrence nomogram score; RFS: Recurrence free survival; OS: Overall survival.
