结肠癌组织HIF-1α和VEGF-C的表达及临床意义

Expressions of HIF-1α and VEGF-C in Colon Carcinoma and Their Clinical Implication

  • 摘要: 目的 探讨结肠癌中缺氧诱导因子1α(HIF-1α)和血管内皮生长因子C(VEGF-C)的表达及其临床意义。 方法 应用SP免疫组织化学技术检测45例结肠癌中HIF-1α和VEGF-C的表达,并分析其与临床病理特征的关系。 结果 HIF-1α在结肠癌中的阳性表达率为66.7%,其中淋巴结转移阳性组的阳性表达率为84.2%,淋巴结转移阴性组的阳性表达率为53.8%,两者比较差异有统计学意义(P<0.05)。VEGF-C在结肠癌中的阳性表达率为53.3%,其中淋巴结转移阳性组的阳性表达率为73.7%,淋巴结转移阴性组的阳性表达率为38.5%,两者比较差异有统计学意义(P<0.05)。结肠癌中HIF-1α和VEGF-C的表达与肿瘤淋巴结转移和浸润深度有关,而与肿瘤大小、患者性别、年龄无关。HIF-1α与VEGF-C的表达呈正相关。 结论 结肠癌中HIF-1α和VEGF-C的表达与淋巴结转移相关。

     

    Abstract: Objective To investigate the expression of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor C (VEGF-C) in colon carcinoma, and to evaluate its clinical implication. Methods Immunohistochemistry (SP) was used to detect the expression of HIF-1α and VEGF-C in 45 tissues of colon carcinoma. The relationship between the expression of HIF-1α and VEGF-C and the clinicopathological parameters was analyzed. Results In 45 cases,the positive rate of HIF-1α was 66.7%. And the positive rate of HIF-1α in colon cancer tissue expression with lymph node metastasis was higher than that without lymph node metastasis (84.2% vs. 53.8%). The positive rate of VEGF-C was 53.3% in colon carcinoma. The positive rate of VEGF-C expression with lymph node metastasis and that without lymph node metastasis was 73.7% and 38.5%respectively. The expression of HIF-1α and VEGF-C was closely correlated with lymph node metastasis and the depth of tumor invasion,but no relationship with tumor size, sex and age. The positive expression of HIF-1α was consistent with the positive expression of VEGF-C. Conclusion The expression of HIF-1α and VEGF-C is correlated with lymph node metastasis in colon carcinoma.
