摘要 探讨 K19m RNA表达与乳腺癌病人淋巴结微转移的关系。应用 RT- PCR方法检测 2 0例乳腺癌组织及其 6 8枚腋下淋巴结和 4份正常乳腺组织、4枚正常淋巴结、5枚良性肿瘤患者腋下淋巴结中 K19m RNA,并与传统病理学检查淋巴结癌转移对照。结果显示 :正常乳腺组织及乳腺癌细胞 K19m RNA检测均为阳性 ,对照正常淋巴结、良性肿瘤患者淋巴结 RT- PCR结果阴性 ;组织病理学检查存在转移的 8枚淋巴结其 K19m RNA检测亦阳性 ,组织病理学检测无转移的 6 0枚淋巴结中有 7枚 K19m RNA RT- PCR检测阳性。因此 ,RT- PCR检测 K19m RNA可更敏感地检出淋巴结中的微转移灶 ,对乳腺癌转移的诊断有一定的实用价值。
