The termination of the study was patients finishing 8 weeks treatment or disease progress.Results 28 patients were evaluable in one-week schedule group: CR 1, PR 7, SD 11, PD 9, RR was 28.6 %,DCR was 67.9 %. 26 patients were evaluable in two-week schedule: none of CR, PR 8, SD 9, PD 9, RR was 30.8 %, DCR was 65.4 %, and no significant difference was found(P >0.05). Grade Ⅲ-Ⅳ toxicity were rash,nausea, vomiting, neutropenia and reduction of leukemia, no significant difference was found in the two groups (P >0.05).
