About this trial
Pancreatic ductal adenocarcinoma (PDAC) accounts for 85-95% of pancreatic cancer and is one of the deadliest tumors in the world, with a survival rate of less than 8%, and identifying key prognostic or predictive factors facilitates risk stratification and prospective assessment in clinical trials. The extracellular matrix (ECM) surrounding PDAC often exhibits a large number of interstitial fibrosis, which is closely related to the formation, development and metastasis of PDAC. High order three-dimensional MR elastography (3D-MRE) allows non-invasive measurements of sheer stiffness in normal pancreas and pancreatic lesions. However, there are no reports about the application of MRE imaging biomarkers to predict the prognosis of PDAC at home and abroad.
