摘要
目的评价国产甲磺酸伊马替尼治疗初诊慢性粒细胞白血病慢性期(CML-CP)患者1年内不同阶段的细胞遗传学、分子生物学反应及安全性。方法回顾性分析2014年1月至11月初诊的50例CML-CP患者资料,患者均121服国产甲磺酸伊马替尼400mg/d,于服药后第3、6、9、12个月分别行细胞遗传学、bcr-abl转录水平及安全性检测。结果50例患者中46例坚持口服国产甲磺酸伊马替尼并随访达1年。治疗3个月时,52.0%(26/50)的患者达到完全血液学反应(CHR),至少达到次要细胞遗传学反应(mCyR)和bcr-abl^IS≤10%的患者比例分别为84.0%(42/50)和42.0%(21/50)。治疗6个月时,至少达到部分细胞遗传学反应(PCyR)和bcr-abl^IS≤10%的患者比例分别为73.5%(36/49)和59.2%(29/49)。治疗12个月时,达到完全细胞遗传学反应(CCyR)、bcr-abl^IS≤1%和bcr-abl^IS≤0.1%患者的比例分别为60.9%(28/46)、63.1%(29/46)和45.7%(21/46)。3级中性粒细胞减少、血小板减少及贫血的发生率分别为34%(17/50)、40%(20/50)和30%(15/50),无4级血液学不良反应发生。常见的非血液学不良反应依次为水肿[84%(42/50)]、恶心[46%(40/50)]、肌肉酸痛[20%(10/50)]、皮疹[16%(8/50)]、肝损害[8%(4/50)]。结论国产甲磺酸伊马替尼治疗初诊CML-CP患者具有一定的疗效,安全性好,是CML-CP患者新的治疗选择。
Objective To evaluate the cytogenetic, molecular responses and safety of generic imatinib in newly diagnosed patients with chronic myelogenous leukemia in chronic phase (CML-CP) in 1-year at different stages. Methods From January 2014 to November 2014, 50 CML-CP patients received oral generic imatinib 400 mg/d. The cytogenetic examinations, bcr-abl transcript levels and safety were monitored after 3, 6, 9 and 12 months respectively. Results 46 of 50 patients insisted on oral generic imatinib and followed up 1 year. At 3-month, 52.0 % (26/50) patients reached the complete hematologic responses (CHR) rate, and patients at least achieved minor cytogenetie response (mCyR) and bcr-abl^IS≤10 % were 84.0 % (42/50) and 42.0 % (21/50). At 6-month, patients at least achieved part eytogenetic response (PCyR) and bcr-abl^IS≤ 10 % were 73.5 % (36/49) and 59.2 % (29/49). At 12-month, patients achieved complete cytogenetic response (CCyR), bcr-abl^IS≤1% and bcr-abl^IS≤0.1% were 60.9 % (28/46), 63.1% (29/46) and 45.7 % (21/46). The grade 3 leukopenia, thrombocytopenia and anemia rates were 34 % (17/50), 40 % (20/50) and 30 % (15/50), respectively. No grade 4 hematologic toxicity occurred. The common non-hematologic toxicities included edema [84 % (42/50)], nausea [46 % (40/50)], muscle pain [20 % (10/50)], rash [16 % (8/50)], and impaired liver function [8 % (4/50)]. Conclusion Generic imatinib has a favorable effect in treatment of patients with CML-CP, and without serious adverse reactions.
