The aim of this study was to analyze a possible correlation between DNA cytometry and Sendai criteria for the differentiation between low-grade intraductal papillary mucinous neoplasms (IPMN-A) and medium-grade dysplasia (IPMN-B). Materials and Methods: Histopathological analysis, DNA index and preoperative Sendai criteria were determined in 16 patients who underwent pancreatic resection for IPMN. Results: All patients with IPMN-B showed aneuploid histograms with DNA indices ≥1.3, whereas three out of four patients with IPMN-A had diploid DNA indices ≤1.3. All 11 patients with one or more high-risk stigmata and aneuploid histograms had IPMN-Bs, whereas both patients who were Sendai-negative and diploid in the DNA analysis had an IPMN-A. Conclusion: DNA index may be an important diagnostic tool for the differentiation of different IPMN types beyond the traditional Sendai criteria. %U https://ar.iiarjournals.org/content/anticanres/37/2/735.full.pdf
