Tumor and nodal staging of colon cancer: accuracy of preoperative computed tomography at a Swedish high-volume center.

ABSTRACT:

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 histopathological stage (pTN). Another aim was to validate the tumor and nodal stage data in the Swedish Colorectal Cancer Registry (SCRCR).

Material and methods

The SCRCR was used to identify patients with colon cancer, treated at a Swedish high-volume center during 2013-2016 (n = 974). Data were gathered from medical records regarding cTN and pTN stage, and predefined patient and tumor var
