胃癌中缺氧诱导因子-1α与Survivin表达的相互关系及临床病理意义

目的 研究缺氧诱导因子.1d(HIF-lα与Survivin在胃癌及正常胃组织中表达的相互关系,探讨其在胃癌的发生、浸润和转移中的作用. 方法 应用免疫组化SP法检测54例胃癌中HIF-lα、Survivin的表达情况,分析HIF-1α、Survivin与胃癌,临床病理因素的关系. 结果 HIF-lα在胃癌中的表达率74.1%,明显高于正常胃组织(0)(P

Expression of HIF-1α and survivin in gastric cancer

Objective To study the expression of HIF-1α and survivin in gastric cancer,and to study their role in tumor angiogenesis,invasion and metastasis.Methods Immunohistochemieal technique was used to detect the expression of HIF-1α and survivin in 54 cases of gastric cancer.Results The expression rate of HIF-lα in gastric cancer (74.1%) was higher than that in normal gastric tissue (O),The expression of HIF-1α in gastric cancer was associated with TNM staging,invasive depth and lymph-node metastasis (P<0.05),The expression of survivin in gastric cancers was high (72.2%),and increased with invasive depth (P<0.01),clinical stages (P<0.01) and lymphatic metastasis (P<0.05).There was a positive correlation between expression of HIF-1α and Survivin (r:0.31,P<0.05).Conclusion HIF-1α and Survivin could be factors in the judgement of the degree of malignancy of gastric cancer and prediction of its prognosis.
