The shortest distance from CHA to the edge of the tumor (A: under 20.55 mm, B: over 20.55 mm). The shortest distance from SMA to the edge of the tumor (C: under 10.9 mm, D: over 10.9 mm). Scale bars: Centimeters are shown in each image.

(A) ROC curve of distance from CHA or SMA in relation to the local recurrence after pancreatic resection. The optimal cut-off level for the distance from CHA was 20.55 mm, with an AUC of 0.617 (95%CI=0.519-0.715, p=0.025). On the other hand, the distance from SMA was 10.9 mm, with the AUC of 0.670 (95%CI=0.578-0.761, p=0.001). Relationship between distance from CHA (B) or SMA (C) and the type of recurrence.

Kaplan-Meier curves of local recurrence-free survival (A and C, respectively) and overall survival (B and D, respectively) in relation to CHA score and SMA score, respectively. Patients in this analysis were classified as recurrence-free and local recurrence group. Both CHA and SMA scores were negatively associated with local recurrence-free survival (p=0.004, p<0.001) and overall survival (p=0.002, p<0.001), respectively.
