MSCT对食管癌术前TNM分期的诊断及临床指导价值分析

Analysis on Value of MSCT in the Diagnosis and Clinical Guidance of Preoperative TNM Staging of Esophageal Cancer

目的MSCT对食管癌术前TNM分期的诊断及临床指导价值分析。方法回顾性分析本院2017年8月至2018年8月收治的104例食管癌患者临床资料,以病理检查结果为“金标准”,计算MSCT对食管癌术前TNM分期的诊断准确率。结果经整理104例患者的临床资料得知,MSCT扫描食管癌患者T分期中,MSCT扫描对T_(1)、T_(2)、T_(3)、T_(4)分期诊断准确率为96.55%、85.71%、85.70%。与病理学分期相比,MSCT扫描对食管癌患者T分期诊断准确率比较无明显差异(P>0.05);MSCT扫描对食管癌患者N分期中,MSCT扫描对N_(0)、N_(1)、N_(2)、N_(3)分期诊断准确率分别为83.33%、86.36%、88.88%、82.14%,与病理学分期相比,MSCT扫描对食管癌患者N分期诊断准确率比较无明显差异(P>0.05)。术前MSCT检查中诊断有远处转移的患者准确率100%,无远处转移的患者准确率100%。结论MSCT对食管癌患者术前TNM分期与术后病理分期的结果有较好的一致性,对临床治疗方案的制定、预后评估均有重要指导作用,具有重要的临床价值。

Objective To analyze the diagnosis and clinical guidance value of MSCT for preoperative TNM staging of esophageal cancer.Methods The clinical data of 104 patients with esophageal cancer admitted to our hospital from August 2016 to August 2018 were retrospectively analyzed.The results of pathological examination were used as the"gold standard"to calculate the diagnostic accuracy of MSCT for preoperative TNM staging of esophageal cancer.Results According to the clinical data of 104 patients,in the T-staging of esophageal cancer in patients by MSCT scan,the accuracy of MSCT scan for T_(1),T_(2),T_(3),T_(4) staging was 96.55%,85.71%,85.70%.Compared with pathological staging,MSCT scan had no significant difference in the accuracy of T-staging of esophageal cancer in patients(P>0.05).In the T-staging of esophageal cancer in patients by MSCT scan,the accuracy of MSCT scan for N_(0),N_(1),N_(2),N_(3) staging was 83.33%,86.36%,88.88%,and 82.14%,respectively.There was no significant difference in the accuracy of N-staging of esophageal cancer in patients between pathological staging and MSCT staging(P>0.05).The accuracy of patients with distant metastases diagnosed by preoperative MSCT was 100%,and the accuracy of patients without distant metastasis was 100%.Conclusion MSCT has a good consistency with postoperative pathological staging for preoperative TNM stagingof esophageal cancer in patients.It plays important guiding role in the development of clinical treatment plan and prognosis evaluation,and has important clinical value.
