目的:探讨CXCR4、血管内皮生长因子- C(VEGF - C) 及受体VEGFR- 3 在原位灶及淋巴结组织
中的表达与宫颈癌转移之间的关系。并探讨这几个因子之间的关系。方法:采用实时荧光定量聚合酶链反应技
术(Real Time PCR),对40 例宫颈癌病人的原位灶组织中的CXCR4 基因和10 例正常宫颈组织中的CXCR4 基
因进行定量检测。用免疫组化方法(SP 法)检测40 例宫颈癌病人的原位灶组织中及淋巴结组织中的VEGF - C
及受体VEGFR- 3 的表达。结果:CXCR4 基因的表达与分化程度、病理类型、年龄无关,与临床分期、淋巴结转
移有关。VEGF - C 阳性表达率与宫颈癌分期、分化程度、病理类型、年龄无相关。与淋巴结转移有相关,VEGF
- C 和VEGFR- 3 表达有显著相关性(P = 0. 022)。但VEGFR- 3 阳性表达率与淋巴结转移无相关。结论:CXCR
4 基因和VEGF - C、VEGFR- 3 两种蛋白表达均与宫颈癌的发生发展相关,VEGF - C 和VEGFR- 3 表达有
显著相关性。

[Abstract]
Objective:To investigate the expression of the chemokine receptor(CXCR4),the vascular
endothelial growth factor - C(VEGF - C) and the vascular endothelial growth factor receptor - 3
(VEGFR- 3)in cervical carcinoma and lymph node. Methods: CXCR4 gene expression in 30 cases
of cervical carcinoma and lymph node tissues,and 10 cases of normal cervical tissues by real time polymerase
chain reaction( real time PCR). Immunohistochemical techniques were used to detect the expression
of VEGF - C and VEGFR- 3 in 30 cases of cervical carcinoma and lymph node tissues. Result:
CXCR4 gene expression and degree of differentiation,histological type,age has nothing to do with
the clinical stage and lymph node metastasis. The rate of positive expression of VEGF - C and cervical
cancer stage,tumor differentiation,histological type,age no correlation. With lymph node metastasis,
VEGF - C and VEGFR- 3 expression was significantly correlated ( P = 0. 022). But no correlation
VEGFR- 3 positive expression rate of lymph node metastasis. Conclusion:CXCR4 gene and VEGF -
C,VEGFR- 3 both protein are associated with the development of cervical cancer,VEGF - C and
VEGFR- 3 expression have a significant correlation.
