多排螺旋CT在术前胃癌T分期中的应用价值

Value of Multi-detector Row Computed Tomography on Preoperative T Staging of Gastric Cancer

    摘要
  • 摘要: 目的：探讨多排螺旋CT（MDCT）在术前胃癌T分期中的应用价值。方法：收集胃癌616例患者，行MDCT术前T分期，与术后病理T分期（pT）对照，用卡方检验分析MDCT T分期准确性与临床-病理学因素相关性。结果：MDCT胃癌T分期总准确度为91%（560/616），其中pT195%（377/396），pT2-3 78%（80/103），pT4a 89%（97/109），pT4b 75%（6/8）。BorrmannⅠ型（P=0.0001）与位于胃窦（P=0.045）或影响MDCT T分期准确性，年龄、性别、肿瘤位于大弯或小弯、肿瘤分化不影响其准确性。结果：MDCT在胃癌术前T分期方面有较高的应用价值。

     

    Abstract: Objective: To study the value of multi-detector row computed tomography (MDCT) before operation in the diagnosis of T-staging of gastric cancer. Methods: 616 patients with gastric cancer underwent MDCT before operation. The results were compared with operative and pathologic T (pT) staging. Especially, we evaluated the correlations among the diagnostic accuracy of T staging and various clinicopathologic parameters by focusing on 276 patients who had detectable lesions by MDCT. Results: The overall diagnostic accuracy of preoperative T staging by MDCT was 91% (560/616). For each pathologic T stage, the accuracy was 95% for pT1, 78% for pT2-3, 89% for pT4a, and 75% for pT4b, respectively. Antral tumors (P=0.045), and Borrmann type1 tumors (P=0.0001) were incorrectly T staged by MDCT. Conclusion: Preoperative T staging of gastric cancer by MDCT have higher clinical value.
