多层螺旋CT在结直肠癌术前TNM分期诊断中的应用

Application value of multi-slice spiral CT in the preoperative TNM stage in colorectal cancer

目的:探讨多层螺旋CT(MSCT)在结直肠癌术前TNM分期诊断中的应用价值。方法:选取2013年1月至2016年5月广西大新县人民医院收治的经病理检查证实为结直肠癌的97例患者,术前1周均行MSCT检查,比较MSCT检查与术后病理检查结果的一致性。结果:MSCT诊断结直肠癌浸润深度(T分期)、淋巴结转移(N分期)、远处转移(M分期)的总体准确率分别为91.8%(89/97)、86.6%(84/97)和97.9%(95/97),Kappa值分别为0.841、0.768和0.921,与病理结果的一致性较好。结论:MSCT在结直肠癌诊断中具有较高的准确率,有助于结直肠癌的早期发现和早期治疗,值得临床推广应用。

Objective. To evaluate multi-slice spiral CT （MSCT） in the diagnosis of colorectal cancer. Methods： From January 2013 to May 2016, 97 colorectal cancer patients who were diagnosed by histological examination in our hospital were recruited in this study. All patients underwent MSCT examination at 1 week pre-operation, and the results were compared with postoperative pathology findings. Results. The overall accuracy of MSCT in the assessment of intestinal wall invasion（T stage）, lymph node metastasis（N stage）and distal metastasis （ M stage） were 91.8% （89/97）, 86.6% （84/97） and 97.9% （95/97）,respectively. The Kappa value were 0. 841, 0. 768 and 0. 921, respectively. Conclusion： MSCT detection had a high accuracy in preoperative staging of colorectal cancer. It could enable the early diagnosis and treatment of colorectal cancer that was worthy of clinical application.
