常规全腹部增强 CT 结直肠癌术前评估的初步研究
Preoperative evaluation of colorectal cancer with whole abdominal enhanced CT scan
摘要
Abstract
Objective To evaluate the accuracy of enhanced CT scan in clinical staging of colorectal cance by detecting the general sit-uation and T and N staging through plain scan combined with enhanced CT scan.Methods Totally 49 cases of colorectal cancer patients were enrolled in this study from May 2015 to October 2015,and it showed no distant metastasis of colorectal cancer in clinical examination. Evaluated the general situation (location,size,and pathologic type)and T and N staging of colorectal cancer through plain scan and enhanced CT scan and multiplanar restructuring.Compared the imaging staging with pathological staging,and respectively calculated the sensitivity,spe-cific degree and accuracy of T and N staging.Evaluated the accuracy of T and N staging with the consistency test,and the differences were statistically significant with P <0.05.Results The location and pathological type of tumor detected by CT scan were compared with the re-sults of operation,and the coincidence rate was 100%.The maximum diameter of the tumor was (2.26 ±1.40)cm from CT image and (2.37 ±1.38)cm from operation measure,and the data were highly correlated (r =0.906,P =0.000).The coincidence rate of T staging was 65.3%,and the consistency was good (k =0.467,P =0.000).The coincidence rate of N staging was 63.3%,and the consistency was good (k =0.440,P =0.000).Conclusion Enhanced CT scan can provide sufficient information for the preoperative evaluation of colorectal cancer,and it has important clinical application value.关键词
