| Outline of Final Research Achievements |
Intraductal papillary mucinous neoplasm (IPMN) is an important type of tumor in pancreatic cancers which has one of the most poor prognosis, because it shows comparatively slow malignant progression from adenoma to carcinoma and patients could expect rather a good prognosis in early stage. However, it remains difficult to determine the surgical indication of a IPMN because the current pre-operative examination which relies on mainly imaging technology is not perfect. In the course of the microRNA array-based approaches to compare plasma microRNA levels of patients having pancreatic tumor, we identified novel plasma microRNAs for cancer detection and monitoring tumor dynamics.
Using large-scale cohort, we validated that levels of miR-223 was significantly higher in pancreatic cancer patients than age-macthed healthy volunteers. Interestingly high expression of miR-223 in plasma significantly related early stage pancreatic tumor including IPMNs.
