摘    要:为探讨髓细胞性白血病(m yeloid leukem ia)患者P-170 蛋白过度表达与预后的关系,用免疫组化LSAB法(labelled streptavidin biotin assay)检测66 例急性髓细胞性白血病(acute m yeloid leukem ia,AML)及20 例慢性髓细胞性白血病(chronic m yeloid leukem ia, CML)患者外周血单个核细胞的P-170 蛋白表达。结果表明,初治组AML患者P-170 表达率为26.5% (9/34);难治/复发组为68.4% (13/19),比初治组明显增高(P< 0.005);完全缓解组为23.1% (3/13),与初治组差异无显著性。诱导化疗P-170+ 者完全缓解(CR)率为22.2% (7/9),P-170- 者为80% (20/25),二者差异有显著性(P= 0.0036)。CML慢性或加速期8 例患者无1 例P-170 表达,急变期患者P-170 表达率为50% (6/12),二者差异有显著性(P= 0.042)。提示P-170 蛋白过度表达是髓细胞性白血病化疗耐药和不良预后的标志

Abstract:Labelled streptavidin biotin immunohistochemical staining technique(LSAB) was used to detect the mdrl associated P glycoprotein (P gp) expression in 66 patients with AML and 20 with CML. In AML patients, 9/34 at diagnosis, 13/19 in relapses or refractory diseases, and 3/13 in CR showed P gp overexpression. The CR rates of induction therapy were 20/25(80%) in P gp - and 2/9(22.2%) in P gp cases(P= 0.0036 ). P gp was also detected in 8/16 CML cases in blast crisis, while none in eight chronic or accelarative cases, P=0.042. P gp overexpression may contribute to drug resistance and poor prognosis in myeloid leukemias.
Keywords:Leukemia   myeloid  Multidrug resistance  P glycoprotein
