Aim: In this study, it was aimed to investigate the prognostic importance of Tumor budding (TB) in Pancreatic ductal adenocarcinomas(PDAC) and its correlation with histopathological findings according to the International Tumor Budding Consensus Conference(ITBCC) grading. Material and Methods: A total of 75 patients diagnosed with PDAC were included in this study. The demographic features of the cases (age, sex) and the macroscopic features of the tumors (localization,size) were obtained from the electronic archive system. All Hematoxylin-Eosin-stained sections were re-evaluated in terms of differentiation, presence of lymphovascular (LVI) and perineural invasion(PNI), surgical margin positivity, primary tumor(pT), lymph node metastasis(LNM) and tumor budding. Statistically, Chi-square test, cox-regression and Kaplan-Meier test were performed. Results:Thirty four of the cases were female and 41 were male. The mean age was 64.21±9.71years. The degree of TB was TB-few in 17 cases, TB-moderate in 25cases, and TB-high in 33cases. LVI, PNI, LNM and TB-high were poor prognostic factors. Moreover, TB-high was related with poor differantiation,LVI,PNI,LNM and short survival time. Tumor budding was independent negative prognostic factor in multivariable model analyzes. Conclusion: ITBCC scoring can also be used in PDACs. In addition, high tumor budding was a poor prognostic feature and might be a target for tumor-specific treatments as it could be a predictive finding for the locally invasive character of the tumor. Evaluation and grading of TB thought to represent EMT may be a histological feature that can be used in tumor selection for advanced molecular methods to identify subtypes that may be associated with poor prognosis and drug resistance.
