摘要
目的 探讨CD44 V6 在乳腺癌中的表达及其意义。方法 应用免疫组织化学SP 法检测54 例乳腺癌组织中CD44 V6 基因蛋白表达变化。结果 乳腺癌CD44 V6 阳性率为59 .3 % (32/54) ,良性肿瘤的阳性率为27 .3 % (3/11) ,P< 0 .05 。有淋巴结转移者CD44 V6 高表达者的阳性率为69 .2 % (18/26) ,低表达者的阳性率为7 .7 % (2/26) 。在无淋巴结转移者中,浸润性癌高表达阳性率为54 .5 % (12/22) ,低表达阳性率为13 .6 % (3/22) ;非浸润性癌高表达阳性率为33 .3 % (2/6) ,低表达阳性率为16 .7 % (1/6) ,P< 0 .05 。结论 CD44 V6 在乳腺癌中的异常表达可能是乳腺癌发生、发展、转移的1 个重要分子学改变。
Objective To investigate the significance and expression of CD44V6 in breast cancer.Methods The expression levels of CD44V6 gene protein in breast cancer tissues were detected by immunohistochemistry.Results The CD44V6 over expression,in 32 of 54 breast cancer tissues,in 3 of 11 benign breast tissues,was detectable, P <0.05.The positive rate of high expression in lymph node metastaiss(69.2%,18/26) was markly higher than that in non lymph nodes metastasis(54.5%,12/22), P <0.05.On the other hand,CD44V6 levels in invasion cancer showed higher expression than in non invasion, P <0.05.Conclusion The present data suggest that the anomalous expression levels of CD44V6 can be an important molecular biological change in breast cancer invasion and metastasis.
