AB Background/Aim: Prediction of local recurrence and distant metastasis is important for patients with pancreatic cancer following pancreatic resection. The aims of this study were to identify a novel prognostic score which combines distance from common hepatic artery (CHA) or superior mesenteric artery (SMA) and examine serum CA19-9 for predicting local recurrence in patients with pancreatic cancer following resection. Patients and Methods: This retrospective study comprised 149 patients who went through elective pancreatic resection for pancreatic cancer between June 2007 and December, 2017. We established new scores (CHA score and SMA score) using the distance between CHA or SMA and the tumor measured by preoperative CT scan in combination with preoperative serum CA19-9 values. We evaluated the relationship between the scores and local recurrence of pancreatic cancer. Finally, we investigated the relationship between the scores and local recurrence-free survival as well as the overall survival. Results: The optimal cut-off levels of the distance between CHA or SMA and the tumor, as determined by ROC analysis, were 20.55 and 10.9 mm, respectively. In a logistic progression model, demonstrated by multivariate analysis, lymphatic invasion (p=0.002), preoperative serum CA19-9 (p=0.007) and SMA score (p=0.004) were identified to be independent predictors of local recurrence in patients with pancreatic cancer following resection. In a Cox progression model, demonstrated by multivariate analysis, intraoperative blood loss (p=0.022), lymphatic invasion (p=0.001) and SMA score (p<0.001) were identified as independent factors of local recurrence. The independent predictors of poor overall survival by multivariate analysis consisted of intraoperative blood loss (p=0.045), intraoperative transfusion (p=0.026) and SMA score (p<0.001). Conclusion: The SMA score may be an independent preoperative predictor of local recurrence and prognosis in patients with pancreatic cancer.
