Radiological tumor density and lymph node size correlate with survival in resectable adenocarcinoma of the pancreatic head: A retrospective cohort study.

Introduction: Tumors within the pancreatic head show a variable density and enhancement on computerized tomography (CT). The relationship between the radiological appearance of pancreatic adenocarcinoma on CT and survival remains unclear. The aim of this study was to evaluate the relationship between the tumor density on CT and survival.
