摘要
目的 探讨CD15mRNA及其蛋白、CD44v6mRNA和nm2 3H1mRNA在乳腺癌组织中的表达及与乳腺癌患者预后的关系。方法 应用催化信号放大 (CSA)原位杂交和免疫组织化学方法 ,对94例乳腺癌患者的癌组织进行了CD15mRNA及其蛋白、CD44v6mRNA和nm2 3H1mRNA表达的检测。结果 CD15mRNA及其蛋白、CD44v6mRNA高表达及nm2 3H1mRNA低表达均与乳腺癌患者的组织学分级、临床分期、淋巴结转移、复发和预后密切相关。CD15mRNA和CD44v6mRNA高表达及nm2 3H1mRNA低表达患者淋巴结转移率高、生存率低。结论 CD15mRNA表达与CD44v6mRNA和nm2 3H1mRNA表达具有正、负调节的协同作用。联合检测 3个基因 ,能更准确地判断乳腺癌的转移和预后状态。
Objective To study the relationship of the expression of CD15 mRNA and its protein, CD44v6 mRNA and nm23H1 mRNA with the clinical pathology parameter and prognosis of breast cancer, and to investigate the correlation of the expression of CD15 mRNA with CD44v6 mRNA and nm23H1 mRNA. Methods Catalyzed signal amplification (CSA) method of in situ hybridization and immunohistochemistry were used to detect the expression of CD15 mRNA and its protein, CD44v6 mRNA and nm23H1 mRNA in 94 cases of breast cancer. Results The overexpression of CD15 mRNA and its protein and CD44v6 mRNA and the low expression nm23H1 mRNA were correlated with the grading, clinical stage, lymph node metastasis, recurrence and prognosis of breast cancer. Patients who had overexpression of CD15 mRNA and CD44v6 mRNA and low expression of nm23H1 mRNA had a higher lymph node metastatic rate and a lower survival rate. Conclusion The expression of CD15 mRNA has a synergistic action in positive and negative regulation with that of CD44v6 mRNA and nm23H1 mRNA. Combining detection of the expression of these three mRNA is a reliable index to evaluate the matastasis, recurrence and prognosis of breast cancer.
