摘要
目的:探讨趋化因子受体4(CXCR4)和血管内皮生长因子C(VEGF-C)在人胃癌组织中的表达及其与淋巴结转移的关系。方法:选择86例胃癌标本,应用免疫组织化学染色方法,检测CXCR4和VEGF-C在人胃癌组织中的表达,同时对其与临床病理参数的关系进行统计学分析。结果:CXCR4在胃癌组织中的阳性表达率为66.28%,其中淋巴结转移组表达率为83.33%,无淋巴结转移组表达率为23.26%,差异非常显著(P〈0.01)。VEGF-C在胃癌组织中的阳性表达率为73.26%,其中淋巴结转移组织表达率为91.67%,无淋巴结转移组织表达率为5.81%,差异非常显著(P〈0.01)。而且,CXCR4阳性表达与VEGF-C阳性表达呈显著正相关(γ=0.498,P〈0.05)。胃癌CXCR4和VEGF-C的表达水平与肿瘤细胞淋巴结转移密切相关,而与病人的组织学类型、分化程度、肿瘤浸润深度和淋巴结转移等有相关性(P〈0.01-0.05)。结论:CXCR4和VEGF-C的表达可作为评估胃癌病人淋巴道转移的一个观测指标。
Objective:To investigate the relationship of the expressions of chemokine CXC receptor 4(CXCR4) and vascular endothelial growth factor C (VEGF- C) with lymph node metastasis in gastric cancer. Methods: Immuohistochemistry was used to detect the expressions of CXCR4 and VEGF - C in 86 samples of human gastric cancer. The relationship between CXCR4 and VEGF - C expressions and the clinical pathological diameters was statistically analyzed. Results: The total positive rate of CXCR4 expression in these samples was 66. 28%, and it was higher in the cases with lymph node metastasis than that without lymph node metastasis(S3.33% vs 23. 26%, P〈0. 01). Meanwhile, the total positive rate of VEGF - C expression was 73. 26%, and was higher in the cases with lymph node metastasis than that without lymph node metastasis (91.67% vs 5. 81%, P〈0. 01). The positive expression of CXCR4 was consistent with the positive expression of VEGF - C(y= 0. 498, P〈0. 05), and the expression levels of CXCR4 and VEGF - C were closely correlated with histological type, cellular differentiation, invasion depth and lymph node metastasis (P〈 0. 01 - 0. 05 ). Conclusion: CXCR4 and VEGF-C expressions may become predictors for the lymphatic metastasis of gastric cancer.
