超声内镜、多层螺旋C T对胃癌患者术前TNM分期诊断及与临床病理特征的相关性分析

Correlation Between Preoperative TNM Staging Diagnosed by Endoscopic Ultrasonography and Multi-Slice Spiral CT and Clinicopathological Features of Gastric Cancer

目的探讨超声内镜(EUS),、多层螺旋计算机断层扫描(MSCT)对胃癌患者术前TNM分期的诊断价值,并对其与临床病理特征的相关性进行分析。方法选取2017年4月至2020年2月本院收治的胃癌患者112例,患者均接受EUS、MSCT检查,以病理学诊断结果为标准,比较EUS、MSCT对胃癌TNM分期的准确性,并对影响两种检测方法准确性的临床病理特征进行相关性分析。结果EUS对胃癌T分期的诊断准确率为85.71%,高于MSCT的74.10%(P﹤0.05);EUS对胃癌M分期的诊断准确率为91.07%,低于MSCT的97.32%(P﹤0.05);Logistic回归分析结果显示,EUS、MSCT的诊断准确率与临床分期相关(P﹤0.05)。结论EUS与MSCT对胃癌术前TNM分期诊断均有一定的应用价值,EUS评估胃壁浅层能力较佳,MSCT对于远处转移的判断更为准确,临床分期是影响EUS、MSCT术前分期诊断准确率的独立因素。

Objective To explore the diagnostic value of endoscopic ultrasonography(EUS)and multi-slice spiral computer tomography(MSCT)for preoperative TNM staging of gastric cancer,and its correlation with clinicopathological features.Methods A total of 112 patients with gastric cancer who were admitted and treated in the hospital from April 2017 to February 2020 were enrolled in the study,all of whom had completed EUS and MSCT examinations.Based on the pathological diagnosis,the accuracy rates of EUS and MSCT for TNM staging of gastric cancer were compared.Correlation analysis between accuracy rates of the two detection methods and clinicopathological features was analyzed.Results The diagnostic accuracy of EUS for T staging of gastric cancer(85.71%)was higher than that of MSCT(74.10%)(P﹤0.05),but the diagnostic accuracy for M staging(91.07%)was lower than that of MSCT(97.32%)(P﹤0.05).Logistic regression analysis showed that the diagnostic accuracy rates of EUS and MSCT were related to clinical staging(P﹤0.05).Conclusion Both EUS and MSCT have certain application value in preoperative TNM staging of gastric cancer.EUS is better for evaluating superficial layer of gastric wall and MSCT is more accurate in judgment of distant metastasis.Clinical staging is an independent factor influencing accuracy rates of EUS and MSCT in preoperative staging diagnosis.
