进展期胃癌CT表现与其组织分化程度的相关性研究

Correlation Analysis of Advanced Gastric Carcinoma CT Expression and Its Histological Differentiation Degree

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=0.0 0 4)、强化差值(Χ2=1 3.2 6,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 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. Conclusionlusion 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.
