64排螺旋CT增强扫描对胃癌术前TNM分期的临床诊断

摘要

Objective:Analysis of 64 row spiral CT enhanced scan for clinical diagnosis of preoperative TNM staging of gastric cancer.Method:In 60 patients with gastric cancer from March 2012 to March 2013 in our hospital,the patients underwent 64 slice spiral CT scan, according to the results of patients with TNM staging diagnosis and staging,diagnosis and pathological results were compared to determine TNM,64 slice spiral CT enhanced scanning in clinical diagnosis value of TNM in staging gastric cancer before operation.Result:The accuracy rate of T1 was 62.5%,the accuracy rate of T2 was 63.6%,the accuracy rate of T3 was 83.3%,the accuracy rate of T4 was 82.3%,the groups was statistically significant difference(P<0.05).The accuracy rate of N0 was 70.8%,the accuracy rate of N1 was 65.0%,the accuracy rate of N2 was 75.0%,the groups was statistically significant difference(P<0.05).The accuracy rate of M0 stage was 88.5%, the accuracy rate of M1 stage was 75.0%,statistically significant differences between the two groups(P<0.05).Toverall accuracy rate was 76.7%, N overall accuracy rate was 70.0%,M overall accuracy rate was 86.7%.Conclusion:64 row spiral CT enhanced scan in the diagnosis of preoperative TNM staging of gastric cancer with high accuracy,can be clearly detected in the early gastric cancer tumor and surrounding tissue,but also can accurately grasp the lymphatic metastasis, and worthy of clinical promotion.%目的：分析64排螺旋CT增强扫描对胃癌术前TNM分期的临床诊断。方法：选取2012年3月-2013年3月笔者所在医院收治的60例胃癌患者，上述患者均接受了64排螺旋CT增强扫描，根据扫描结果对患者进行TNM分期诊断，并与病理TNM分期诊断结果进行对比，判断64排螺旋CT增强扫描对胃癌术前TNM分期的临床诊断价值。结果：T1期准确率为62.5%，T2期准确率为63.6%，T3期准确率为83.3%，T4期准确率为82.3%，各期比较差异有统计学意义(P<0.05)。N0期准确率为70.8%，N1期准确率为65.0%，N2期准确率为75.0%，各期比较差异有统计学意义(P<0.05)。M0期的准确率为88.5%，M1期的准确率为75.0%，两期比较差异具有统计学意义(P<0.05)。T期整体准确率为76.7%，N期整体准确率为70.0%，M期整体准确率为86.7%。结论：64排螺旋CT增强扫描对胃癌术前TNM分期具有较高的诊断准确率，可以在胃癌早期清晰地探测到肿瘤以及周围组织情况，同时也能够对淋巴转移情况进行准确的把握，值得临床推广。
