摘  要:目的观察甲磺酸伊马替尼(IM)治疗慢性髓系白血病(CML)的疗效,外分析血浆药物谷浓度水平与临床疗效及不良反应的关系。方法观察101例CML患者接受IM治疗的疗效,并采用液相色谱-串联质谱法检测其中30例CML-慢性期(CP)患告IM血浆药物谷浓度结果(1)89例CML-CP患者总的完全血液学缓解率(CHR)、主要细胞遗传学缓解率(MCyR)、完全细胞遗传学缓解率(CCyR)和BCR—ABL融合基因转阴率分别为96.6%、86.5%、77.5%和47.2%;12例CML,进展期(加速期和急变期)患者的CHR、MCyR、CCyR、BCR—ABL转阴率分别为58.3%、25.0%、25.0%、8.3%②服用IM1年时获得CCyR患者的平均血浆药物谷浓度[(1472±482)μg/L]明显高于未获得CCyR者[(1067±373)μg/L],两者间差异有统计学意义(P〈0.05)。服用IM1午时扶得主要分子学缓解(MMR)患者的平均血浆药物谷浓度[(1624±468)μg/L]也明显高于未获得MMR的患者(1137±404)μg/L,P〈0.05]。结论IM明显提高CML患者细胞遗传中和分子学疗效。CML-CP期患者的疗效(1年时CCyR与MMR)与IM血浆药物谷浓度之间存住相关性.Objective To analyze the clinical efficacy of imatinib mesylate( IM ) for Ph-posiliw. or BCR-ABL positive chronic myeloid leukemia(CML) to couple the trough plasma eoncentrations (Cmins) of IM with clinical responses and adverse events(AEs). Methods One hundred and one CMI, patients mceived IM therapy, and Cmins of IM were determmined in 30 patients. Results (1)Cumulative complete hematological response( CHR), major eytogenetic response ( MCyR ), complete eytogenetie response ( CCyR ) and negative BCR/ABL fusion gene rates were 96.6% , 86.5% ,77.5% and 47.2% , respectively, in CML- CP patients. In accelerated and blastic phases( AP and BC) patients, CHR, MCyR, CCyR and negative BCR-ABL fusion gene rates were 58.3% , 25.0% , 25.0% , 8.3% , respectively. (2)Mean Cmins of IM was significantly higher in the CCyR at 1 year [ (1472 ± 482) μg/Ll group than in the non-CCyR at 1 years group [ ( 1067 ±373)Ixg/L] (P 〈 0.05), and higher in the MMR at 1 year group than in the non-MMR at I years group [(1624±468) μg/L vs (1137 ±404) μg/L, P〈0.051. Conclusion IM significantly improves eytogenetic and molecular response, envent-fi'ee survival, and overall survival for patients with Ph-positive CML. The Cmins of IM exerts a significant impact on clinical response ( CCyR and MMR at 1 year).
