摘要 目的 探讨乳腺癌患者外周血中 CK- 19m RNA的表达 ,建立检测外周血早期诊断乳腺癌微转移的方法。方法 采取 6 5例乳腺癌和 37例乳腺良性疾病患者的外周血 ,分离其有核细胞后进行细胞总 RNA的抽提 ,运用巢式 RT- PCR技术进行 CK- 19m RNA的检测。结果 以巢式 RT- PCR终产物出现 4 6 0 bp带定为阳性。 6 5例乳腺癌患者 CK- 19m RNA有 2 4例表达 ,总阳性率为 36 .92 %。37例乳腺良性疾病者 CK- 19m RNA无一例表达。两组有统计学意义 (χ2 =7.4 1,P<0 .0 0 1)。结论  RT- PCR可以用于临床检测乳腺癌患者外周血中微转移 。
