摘要
目的 :研究nm2 3基因两个亚型表达与乳腺癌发生转移因素之间的关系。方法 :用半定量RT PCR方法 ,检测 30例乳腺癌组织nm2 3 H1 和nm2 3 H2 mRNA的表达 ,分析其与乳腺癌转移的关系。结果 :淋巴结阳性的原发灶组织nm2 3 H1 mRNA表达明显低于淋巴结阴性的原发灶组织 ,Ⅲ期乳腺癌组织nm2 3 H1 mRNA水平较Ⅰ、Ⅱ期的明显低 ,多因素分析发现淋巴结转移与nm2 3 H1 mRNA的表达有显著性相关。nm2 3 H2 mRNA表达与乳腺癌患者肿瘤大小、淋巴结状况、绝经状况、激素受体状况、TNM分期之间无显著性相关。结论 : nm2 3 H1 mRNA的表达强度与乳腺癌淋巴结转移呈负相关。nm2 3 H1 mRNA较nm2 3 H2 mRNA在乳腺癌转移过程中起更重要的作用。nm2 3 H1
Purpose:To investigate the expression and clinical significance of nm23 H 1 and nm23 H 2 in human breast cancer. Methods:A semi quantitative reverse transcription polymerase chain reaction was performed to detect the expression of nm23 H 1 and nm23 H 2 mRNA in thirty human breast cancer specimens. To evaluate the relationship between nm23 gene and breast cancer metastasis t test, F test and multivariate analysis were used.Results:The nm23 H 1 mRNA level in primary breast cancer tissue with lymph node positive was lower than that with lymph node negative. The nm23 H 1 mRNA level in breast cancer with Ⅰ,Ⅱstage was higher than that with Ⅲ stage. Lymph node metastasis was the only parameter that was significantly correlated with the nm23 H 1 expression. There was no significant relation between nm23 H 2 and tumor size, lymph node status, TNM stage, hormone receptor and menopausal status.Conclusions:nm23 H 1 mRNA show a significant inverse correlation with lymph node metastasis. nm23 H 1 appears to play a more important role than nm23 H 2 in breast cancer. nm23 H 1 mRNA expression may be a predictor of lymph node metastasis.
