140例结肠癌术前CT TNM分期与术后病理分期的相关性

目的:探讨结肠癌CT TNM分期与病理分期的相关性。方法:行CT检查结肠癌140例,其中平扫104例,平扫加增强36例,将其结果进行TNM分期,并与术后临床病理分期进行对照。结果:104例平扫CT患者术前的T、N、M及TNM分期诊断准确率与术后病理相比分别为84.62%(88/104)、71.15%(74/104)、85.58%(89/104)、81.73%(85/104),均具有中度一致性(均P0.001)。36例平扫加增强CT患者的诊断准确率分别为91.67%(33/36)、75%(27/36)、100%(36/36)、83.33%(30/36),均具有中度、完全、中度一致性(均P0.001)。结论:CT与病理无论T、N、M分期还是TNM综合分期,都具有中度以上的一致性,可作为结肠癌术前分期的有效的评估方法。

Correlative Analysis of Colon Cancer TNM Staging between Computed Tomography and Post-operative Pathologic Staging

Objective To evaluate correlations of the TNM staging of colon cancer between computed tomography （CT） and surgical pathologic staging. Methods In 140 patients with colon cancer, 104 of them were examined by plain CT scan and 36 examined by plain CT scan and enhanced CT before operation, then the findings of TNM staging of CT were compared with post-operative pathologic TNM staging. Results The diagnostic accuracy of plain CT scan about T-stage, N-stage and M-stage and TNM stage in 104 patients with colon cancer was 84.62% （88/104）, 71.15 （74/104）, 85.56% （89/104）, 81.73% （85/104） respectively, all were medium consistent with post-operative pathologic staging （P0.001）. The diagnostic accuracy of 36 cases was 91.6% （33/36）, 75% （27/36）, 100% （36/35）, 83.33 （30/36） respectively. T-staging and N-staging were more mediumer consistent than with post-operative pathologic staging （P0.001）. M staging was strongly consistent with post-operative pathologic staging （P0.001）. Conclusion T, N, M staging and TNM staging of CT were all medium consistent with post-operative pathologic staging. CT can serve as an effective method to evaluate preoperative patients with colon cancer.
