Methods and materials

Sixty patients with PNETs undergoing radical surgery from 2009 to 2018 were recruited into this retrospective study. MR imaging features(pancreatic atrophy, tumor shape, tumor size and lymph node metastasis), tumor grading of WHO 2017, and intravascular tumor embolus on samples were assessed by Cox proportional hazard ratio regression to confirm predictors of progression-free survival (PFS). The cumulative recurrence rate was calculated by the Kaplan-Meier method and the log-rank test was performed to compare the different PFS.
