【摘要】：目的探讨T2期胃癌原发病灶的CT特征及临床病理特征。方法回顾性分析93例经病理证实为T2期胃癌患者的胃壁黏膜厚度及其增强各期ΔCT值的变化,并行单因素分析浅肌层癌(T2a)和深肌层癌(T2b)患者的临床病理特征。结果浅肌层癌(T2a)和深肌层癌(T2b)两组患者在临床病理特征上无统计学意义上的差异(P0.05)。93例T2期胃癌均显示胃壁有不同程度的增厚。胃癌病变处粘膜厚度(5.44±1.58)mm较正常组粘膜厚度(2.27±0.50)mm明显增厚(t=10.812,P0.0001)。T2期胃癌与正常对照组间动脉期、门脉期及平衡期ΔCT值比较差异均有统计学意义(t=2.336,P=0.021;t=4.661,P0.0001;t=3.480,P=0.0001)。结论螺旋CT增强扫描对T2期胃癌诊断具有重要的临床价值。浅肌层癌(T2a)和深肌层癌(T2b)患者临床病理特征上无明显差异。
[Abstract]:Objective to investigate the CT features and clinicopathological features of primary gastric cancer in T 2 stage. Methods the changes of gastric wall mucosal thickness and its enhanced 螖 CT values in 93 patients with pathologically proved T2 gastric cancer were analyzed retrospectively. The clinicopathological features of superficial muscular carcinoma (T2a) and deep muscular carcinoma (T2b) were analyzed by univariate analysis. Results there was no significant difference in clinicopathological features between superficial muscular carcinoma (T2a) and deep muscular carcinoma (T2b) (P0.05). The mucosal thickness of gastric cancer (5.44 卤1.58) mm was significantly thicker than that of normal group (2.27 卤0.50) mm (t _ (10.812) P _ (0.0001). The 螖 CT values of arterial phase, portal vein phase and equilibrium phase of gastric cancer in T2 stage were significantly different from those in normal control group (t _ (2.336P0.021) ~ (4.661) P _ (0.0001) P _ (0.480) P _ (0.0001). Conclusion Spiral CT enhanced scan has important clinical value in the diagnosis of T 2 gastric cancer. There was no significant difference in clinicopathological features between superficial muscular carcinoma (T 2a) and deep muscular carcinoma (T 2 b).
