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

Figure 3 Construction of the recurrence nomogram. A-C: Correlations between serum recurrence score (SRS) and tumor site, tumor differentiation, and tumor stage. Higher SRS was observed in the head/neck group, the poor differentiation group, and the advanced stage group; D: Univariate Cox regression analysis and Forest plot of SRS and 18 clinicopathological variables; E: Multivariate Cox regression analysis and Forest plot of the independent risk factors of recurrence. SRS: Serum recurrence score.
