METHODS: Polymerase chain reaction (PCR) was used to detect FLT3 gen e expression, and FLT3/ITD gene mutation in 53 CML patients of chronic phase, an d 34 CML patients of accelerated phase or blast crisis.

• 方法:采用聚合酶链反应(polymerasechainreaction,PCR)检测53例CML慢性期和34例CML加速期或急变期患者DNA水平FLT3基因及FLT3/ITD基因突变。
