Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０和Ｆａｓ在乳腺癌中的表达及其意义

目的　探讨人乳腺癌组织、癌旁正常乳腺组织中Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０和Ｆａｓ的表达及其临床意义。方法　应用免疫组化法检测３６例患者的乳腺癌组织及癌旁正常乳腺组织标本中Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０和Ｆａｓ蛋白的表达情况。结果　Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０和Ｆａｓ在乳腺癌组织中的阳性表达率分别为８３.３％、８６.１％和５２.８％，在癌旁组织中表达率分别为４１.７％、６３.９％和９７.２％。Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０在乳腺癌组织中的阳性表达率明显高于癌旁正常乳腺组织，而Ｆａｓ在乳腺癌组织中的阳性表达率明显低于癌旁正常乳腺组织。Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０和Ｆａｓ的表达与年龄、病理类型、肿瘤直径、ＨＥＲ-２无显著性差异（Ｐ＞０.０５）；Ｓｕｒｖｉｖｉｎ和ＨＳＰ７０的表达率在有淋巴结转移组明显高于无淋巴结转移组（Ｐ＜０.０５），而Ｆａｓ的表达率在有淋巴结转移组明显低于无淋巴结转移组（Ｐ＜０.０５）；且Ｓｕｒｖｉｖｉｎ在ＥＲ（－）／ＰＲ（－）组表达率高（Ｐ＜０.０５）。Ｓｕｒｖｉｖｉｎ与Ｆａｓ表达呈负相关（ｒ＝－０.４２３，Ｐ＜０.０５）；Ｓｕｒｖｉｖｉｎ与ＨＳＰ７０表达无明显相关性（ｒ＝０.２５１，Ｐ＞０.０５）。结论　Ｓｕｒｖｉｖｉｎ、ＨＳＰ７０上调及Ｆａｓ下调可能在乳腺癌发生发展中起着一定的作用。

Expression and significance of survivin,HSP70 and Fas proteins in breast cancer

Objective To investigate the expression levels and clinical significance of survivin,HSP70 and Fas proteins in the breast carcinoma tissue and paracancerous tissue.Methods The expression of survivin,HSP70 and Fas proteins was detected by immunohistochemistry(IHC) in 36 breast cancer and paired paracancerous tissues.Results The positive expression of survivin,HSP70 and Fas proteins in breast cancer tissues and paracancerous tissues was 83.3%,86.1%,52.8% and 41.7%,63.9%,97.2%,respectively.The rates of express...
