Abstract

Chronic myeloid leukemia is increasingly viewed as a chronic illness; most patients have a life expectancy close to that of the general population. Despite progress made using BCR-ABL1 tyrosine kinase inhibitors (TKIs), drug resistance via BCR-ABL1-dependent and BCR-ABL1-independent mechanisms continues to be an issue. BCR-ABL1-dependent resistance is primarily mediated through oncoprotein kinase domain mutations and usually results in overt resistance to TKIs. However, BCR-ABL1-independent resistance in the setting of effective BCR-ABL1 inhibition is recognized as a major contributor to minimal residual disease. Efforts to eradicate persistent leukemic stem cells have focused on combination therapy.

摘要

慢性髓性白血病越来越被视为一种慢性疾病;大多数患者的预期寿命接近普通人群。尽管使用BCR-ABL1酪氨酸激酶抑制剂(TKIs)取得了进展,但通过BCR-ABL1依赖性和BCR-ABL1非依赖性机制产生的耐药性仍然是一个问题。BCR-ABL1依赖性耐药主要通过癌蛋白激酶结构域突变介导,通常导致对TKIs的明显耐药。然而,在有效的BCR-ABL1抑制情况下,BCR-ABL1非依赖性耐药被认为是微小残留病的主要促成因素。根除持续存在的白血病干细胞的努力集中在联合治疗上。
