摘 要:目的比较伴t(8;21)和正常核型的急性髓系白血病(AML)M:患者在诱导缓解后,应用含大剂量阿糖胞苷(HD-Ara-C)方案进行强化巩固治疗的疗效。方法伴t(8;21)(q22;q22)AML.M:患者2l例,正常核型AML—M:患者23例,在诱导缓解后,给予4个疗程HD—Ara-C方案强化治疗:Ara-C3.0g/m^2,每12h1次,静脉滴注持续3h,第1—3天,同时交替联合使用其他药物(米托蒽醌7mg·m^-2·d^-1第1—3天或阿克拉霉素30mg·m^-2·d^-1第1—3天或依托泊甙70mg·m^-2·d^-1第1~3天等)。结果伴t(8;21)患者组复发率29%,3年总体生存(OS)率76%,3年无病生存(DFS)率71%;正常核型组复发率57%,3年OS率65%,3年DFS率43%。两组患者复发率及3年DFS率差异有统计学意义(P〈0.05),3年OS率差异无统计学意义(P〉0.05)。结论伴t(8;21)AML-M2患者诱导缓解后,应用4个疗程含HD-Ara-C方案进行强化巩固治疗,复发率低,可以提高DFS率。Objective To compare the efficacy of high-dose cytarabine (HD-Ara-C) based chemotherapy for post-remission treatment in patients with t (8;21) (q22 ;q22 ) AML-M2 and those with normal karyotype AML-M2. Methods AML-M2 patients were grouped into with (21 cases) or without (23 cases) t(8; 21 ) ( q22 ; q22 ) karyotype groups. After achieved remission by induction therapy, all patients received four cy- cles of HD-Ara-C (3 mg/m2 per 12 hours by three-hour infusion day 1 to day 3)with either mitoxantrone (7·m^-2·d^-1)or aclarubicin (30 mg·m^-2·d^-1 ) or etoposide(70 mg·m^-2·d^-1)for 3d as post-remission treatment. Results Relapse rate in the t (8;21) and the normal karyotype groups was 29% and 57% respectively ( P 〈 0.05 ) ; 3 year disease-free survival (DFS) rate was 71% and 43% respectively ( P 〈 0.05 ). and 3 year over-all survival (OS) rate was 76% and 65% respectively ( P 〉 0.05 ). Conclusion Four cycles of high-dose eytarabine based combination chemotherapy as post-remission treatment improves long-term disease-free survival in patients with t( 8 ;21 )( q22 ;q22) AML-M2.
