难治性复发成人急性淋巴细胞白血病的治疗

日的:回顾性分析氟达拉滨(Flu)为主的方案与替尼泊苷 米托蒽醌(MIT)的方案对难治性复发成人急性淋巴细胞白血病(ALL)的疗效及毒副作用.方法:应用替尼泊苷(100 mg/d,5～7 d) MIT(10 mg/d,2 d)的方案和Flu为主的方案Flu 30 mg/(m2·d),3～5 d,阿糖胞苷(Ara-c)1～2g/(m2·d),5 d;及Flu(50 mg/d,5 d),Ara-c(200 mg/d,5 d),MIT(4 mg/d,4 d)]治疗42例难治复发成人ALL.WBC＜1.0×109/L时使用粒细胞集落刺激因子(G-CSF)5μg/(kg·d)直至WBC＞1.0×109/L.结果:以Flu为主的方案与替尼泊苷 MIT方案(VM)相比:完全缓解(cR)率分别为45%和31.8%,P＞0.05;中性粒细胞最低的中位时间均为第6天,WBC＜1.0×109中位持续时间分别为10 d和7.5 d,P＞0.05;血小板最低的中位时间分别为第10天和第6.5天,P＜0.05;PLT＜20.0×109中位持续时间分别为第6天和第10天,P＞0.05.Flu组非血液学毒副作用显著少于VM组.结论:两组方案对难治复发ALL均有效,Flu方案毒副作用小,骨髓抑制略轻,缓解率较高,尤其对Ph ALL疗效显著.

Treatment of refractory and relapsed acute lymphocytic leukemia in adults

OBJECTIVE: To analyze on the efficacy and toxicity of fludarabine and teniposide + mitoxantrone (MIT) regimens on treating refractory and relapsed acute lymphocytic leukemia in adult patients. METHODS: Teniposide 100 mg/d, 5-7 d, MIT 10 mg/d, 2 d and fludarabine regimens Flu 30 mg/(m(2) . d), 3- 5 d, Cytarabine (Ara-c )1-2 g/(m(2) . d), 5 d; Flu 50 mg/d, 5 d, Ara-c 200 mg/d, 5 d, MIT 4 mg/d, 4 d] were used to treat 42 cases of adults with refractory and relapsed acute lymphocytic leukemia(ALL). G-CSF 5 microg/(kg . d) were used when WBC<1.0 x 10(9)/L. RESULTS: In both the regimens fludarabine and VM (teniposide + MIT), the complete remission (CR) rate was 45% versus 31.8% (P>0.05); the median neutropenia began 6 days after the regimens arresting and lasting 10 versus 7.5 days, P>0.05; thrombocytopenia begin at time of 10 versus 6.5 days (P<0.05) after the regimens arresting and lasting 6 versus 10 days (P>0.05). Fludarabine regimen had less non-haematological toxic effect than that of VM. CONCLUSION: Compared with VM, Fludarabine regimen was a very effective alternative treatment for CR induction in adult patients with refractory and relapsed ALL and low toxicity.
