VEGF-C表达与子宫颈癌侵袭转移的关系探讨

    Expression of VEGF-C and its relationship to invasion and metastasis of cervical carcinoma

    • 摘要: 目的: 探讨血管内皮生长因子-C (VEGF-C)在早期子宫颈癌组织中的表达及与子宫颈癌侵袭、转移的关系。方法: 应用免疫组化S-P法检测63例子宫颈癌及20例正常子宫颈组织VEGF-C表达,以CD34检测子宫颈癌组织中微血管密度,分析VEGF-C的表达与子宫颈癌的组织学类型、临床分期、细胞分化程度、淋巴结转移及肿瘤微血管密度的关系。结果: VEGF-C在正常子宫颈组织中不表达,在子宫颈癌中的阳性表达率为61。2%。VEGF-C表达与子宫颈癌盆腔淋巴结转移呈正相关,VEGF-C阳性表达患者腹膜后淋巴结转移率48。8%。阴性表达患者淋巴结转移率15。0%(P=0。01)。VEGF-C表达水平与肿瘤大小、临床分期、年龄、组织学类型及分级无关(P>0。05)。VEGF-C表达与子宫颈癌微血管密度无明显关系(P>0。05)。结论: VEGF-C表达与肿瘤盆腔淋巴结转移有关,而与肿瘤微血管密度无明显关系。VEGF-C表达增强预示子宫颈癌盆腔淋巴结转移。

       

      Abstract: Objective: To study the expression of vascular endothelial growth factor-C(VEGF-C) in the early stage of cervical carcinoma and its relationship with the lymphnode metastasis in cervical carcinomas.Methods: Immunohistochemistry S-P method was used to detect the expression of VEGF-C in 20 cases of normal cervical tissues and 63 cases of cervical cavcinoma.The microvessel density was detected with CD34 in VEGF-C positve and negative groups respectively.The correlation between VEGF-C and histological types,cell differentiation,clinical stages,lymph nodes metastasis and the microvessel density was analyzed stastistically.Results: VEGF-C was expressed in cervical carcinomas but not in normal cervical tissues.The positive rate of VEGF-C was 61.2% in cervical carcinomas.There was positive correlation between the expression of VECF-C and lymph node metastasis in cervical carcinomas.The lymph node metastasis rate was 48.8% in patients with VEGF-C positive and 15.0% in patients with VEGF-C negative(P=0.01).The expression level of VEGF-C was not related to the tumor size,histological types or cell differentiation(P>0.05).The expression of VEGF-C was not related to tumor microvessel dentisty in cervical carcinomas(P>0.05).Conclusions: Expression of VEGF-C in cervical carcinomas was significantly associated with lymph node metastasis in cervical carcinoma,but the expression has no relation with the tumor microvessel dentisty.The increase of VEGF-C suggests lymphnode metastasis.VEGF-C plays an important role in promoting pelvic lymph node metastasis in cervical carcinomas.
