目的对进展期胃癌患者的CT表 现和患者组织分化程度进行相关性研究。 方法 选取我院2012年1月-2014年6月收入 的82例进展期胃癌患者，所有患者经活 检显示为进展期胃癌，对患者进行CT检 查，分析进展期胃癌患者的CT表现和患者 组织分化程度进行相关性。结果 82例进 展期胃癌患者中息肉型9(10.98%)，溃疡 型10(12.20%)，浸润型63(76.83%)，总 体准确率98.78%(Χ2 =13.12，P=0.002)， 具有统计学意义。CT显示82例进展期胃 癌患者中高分化32(39.02%)，中分化 26(31.71%)，浸润型24(29.27%)，总体 准确率84.15%(Χ2 =11.29，P=0.003)， 具有统计学意义。将CT表现与组织分化 关系进行统计，并进行Pearson分析表明 进展期胃癌患者肿瘤厚度(Χ2 =12.35， P=0.003)、淋巴结转移(Χ2 =9.64， P=0.004)、强化差值(Χ2 =13.26， P=0.002)与组织分化程度有关(rs =0.46， P=0.003)，具有统计学意义。结论 进展 期胃癌患者的CT表现和患者组织分化程度 密切相关，多层螺旋CT能够准确的评价进 展期胃癌的组织分化程度。

Objective To study the correlation between the CT expression and the degree of tissue differentiation in patients with advanced gastric cancer. Methods 82 cases with advanced gastric cancer were selected from January, 2012 to June, 2014 who were admitted in our hospital, all the patients revealed advanced gastric cancer by biopsy, CT was performed on these patients, to analyze the correlation between the CT expression and tissue differentiation degree. Results 82 cases of advanced gastric cancer patients which are 9 (10.98%)of polyp type, 10 (12.20%) of ulcerative type, 63 (76.83%) of infiltration type, the overall accuracy of 98.78% (X2 =13.12, P=0.002), with statistical significance. CT revealed 82 patients with advanced gastric cancer in high differentiation of 32 (39.02%), 26 (31.71%) in medial differentiation, 24 (29.27%) of infiltration type, the overall accuracy of 84.15% (X2 =11.29, P=0.003), with statistical significance. Pearson analysis showed that the thickness of disease progression in patients with gastric cancer (X2 =12.35, P=0.003), lymph node metastasis (X2 =9.64, P=0.004), the difference value of enhancement(X2 =13.26, P=0.002) related to the degree of differentiation (rs =0.46, P=0.003), with statistical significance. Conclusion CT expression is closely related to tissue differentiation in patients with advanced gastric cancer. Multi slice spiral CT can accurately evaluate its degree of histological differentiation.
