PDFAbstract
Objective To investigate the clinical value of CT on preoperative diagnosis of colon cancer and diagnosis of postoperative recurrence. Methods Thirty patients with colon cancer admitted by the inpatient department of the hospital from June, 2013 to June, 2014 were selected as research subjects, who were subject to preoperative condition assessment by stages and monitoring of postoperative recurrence through CT, and simultaneously CT diagnosis were evaluated with pathological diagnosis as the standard. Results The comparison between preoperative staging accuracies of CT in the diagnosis of colon cancer at Period I and Period Ⅱ and diagnosis results of histopathologic tissue satisfied χ2 =14.97 and 16.13 respectively, the comparison between postoperative staging accuracies at Stage Ⅰ and Stage Ⅱ and diagnosis results of histopathologic tissue satisfiedχ2 =66.33 and 39.32 (average P<0.05), and the differences were statistically significant. Both diagnostic accuracies in StageⅢ and Stage Ⅳbefore operations were 100.00%. Conclusions CT could be used for the assessment of preoperative staging of colon cancer, evaluate the recurrence and metastasis, demonstrate the tumor infiltrating of the adjacent tissue, and prompt the metastasis of lymph nodes and distant organs. The diagnostic accuracy of CT is high and deserve widely used in clinical.
