Tumor and nodal staging of colon cancer : accuracy of preoperative computed tomography at a Swedish high-volume center
Background: When deciding treatment options for patients with colon cancer, accurate staging is required. In Sweden, the main preoperative evaluation modality to determine tumor and nodal stage is computed tomography (CT).Purpose: The aim of this study was to investigate how well the preoperative (CT-determined) clinical tumor and nodal stage (cTN) correlated with the postoperative histopathologic
