This study focused on the potential of extracellular volume (ECV) fraction measured by Gd-EOB-DTPA-enhanced MRI as a prognostic factor in patients with metastatic pancreatic adenocarcinomas. The effect on survival of variables including age, sex, tumor location, tumor size, TNM factors, serum carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (CEA) levels and tumor ECV fraction was assessed in patients with metastatic adenocarcinoma. Our results showed that pancreatic adenocarcinoma with higher ECV fraction had better prognosis. Therefore, ECV fraction measured by MRI before and 5 min after Gd-EOB-DTPA administration may be a useful semiquantitative marker of patient prognosis in metastatic pancreatic adenocarcinoma.
