To investigate the value of 640 slice CT in the staging of colon cancer.
Methods:
The data of sixty-seven patients with colon cancer confirmed by postoperative histopathology were retrospectively analyzed. The results of preoperative T staging by CT were compared with the gold standard.
Results:
The overall diagnostic accuracy of T staging was 88.1% by 640 slice CT. The diagnostic accuracies of T2
T3
T4a and T4b stages were 97.0% (65/67)
88.1% (59/67)
94.0% (63/67) and 97.0% (65/67)
respectively. The agreement between two observers was good (Kappa=0.707).
Conclusion:
640 slice CT may provide accurate preoperative T staging of colon cancer
which is an important reference for the clinical management of patie
