摘要: 目的 研究缺氧诱导因子-2α(HIF-2α)在子宫颈鳞癌组织中的表达情况及与肿瘤生物学特征的关系。方法 免疫组织化学染色方法检测子宫颈鳞癌组织中HIF-2α的表达。结果 40例子宫颈鳞癌组织中HIF-2α阳性表达得分为4.51±1.04,明显高于15例正常子宫颈组织的得分(2.28±1.60,P<0.001);子宫颈鳞癌患者中,有淋巴结转移的组织得分为5.00±0.89,也明显高于无淋巴结转移组织的得分(4.00±0.83,P<0.01);HIF-2α的阳性表达与子宫颈鳞癌患者的年龄无关,与子宫颈癌组织的FIGO2009分期、肿瘤大小有关。结论 HIF-2α的表达与子宫颈鳞癌的生长、侵袭有密切关系。

Abstract: Objective To investigate the relationship between hypoxia inducible factor-2 alpha (HIF-2α) expression and tumor biological characteristics in cervical cancer tissues.   Methods The expression of HIF-2α in cervical cancer tissues was detected by immunohistochemistry staining method.   Results The score of HIF-2α positive expression in 40 samples of cervical cancer tissues was 4.51±1.04. Compared with the score of 2.28±1.60 for 15 samples of normal cervical tissues, there was statistical significance between them (P<0.001). In 40 samples of cervical cancer tissues, the score of HIF-2α positive expression in the samples with lymph node metastasis (5.00±0.89) was higher than that without lymph node metastasis (4.00±0.83, P<0.01).  Although there was no relationship between the age of the patients and HIF-2α positive expression, the relationship of FIGO2009 staging and size of the tumor with HIF-2α positive expression was found.   Conclusions The expression of HIF-2α correlates closely with the growth and invasion of cervical cancer.
