To investigate the efficacy and safety of IA regimen which contains idarubicin (IDA) 8 mg/m(2), 10 mg/m(2) or 12 mg/m(2) as induction chemotherapy for adult patients with de-novo acute myeloid leukemia (AML) . A total of 1 215 newly diagnosed adult AML patients, ranging from May 2011 to March 2015 in the First Affiliated Hospital of Soochow University and other 36 clinical blood centers in China were enrolled in the multicenter, single-blind, non-randomized, clinical controlled study. To compare the response rate of complete remission (CR) , adverse events between different dose idarubicin combined with cytarabine (100 mg/m(2)) as induction chemotherapy in newly diagnosed patients of adult AML. Of 1 207 evaluable AML patients were assigned to this analysis of CR rate. The CR rates of IDA 8 mg/m(2) group, IDA 10 mg/m(2) group and IDA 12 mg/m(2) group were 73.6% (215/292) , 84.1% (662/787) and 86.7% (111/128) , respectively (<0.001) . After adjusted for age, blast ratio of bone marrow, FAB classification and risk stratification, the odds ratios (95% ) of IDA 10 mg/m(2) group and IDA 12 mg/m(2) group were 0.49 (0.34-0.70) and 0.36 (0.18-0.71) , as compared with the IDA 8 mg/m(2) group (<0.001, =0.003) . In the intermediate and favorable groups, CR rates was 76.5% (163/213) , 86.9% (506/582) and 86.1% (68/79) in different doses of IDA (=0.007) . Interestingly, IA regimen with IDA 10 mg/m(2) was the only beneficial factor affecting CR in this group after adjusted for age, blast ratio of bone marrow and FAB classification[=0.47 (95% 0.31-0.71) , <0.001]. CR rates in adverse group was 50.0% (18/36) , 60.6% (43/71) and 81.8% (18/22) respectively (=0.089) . However, the odds ratios (95% ) of IDA 12 mg/m(2) when compared with the IDA 8 mg/m(2) was 0.22 (0.06-0.80) , after adjusted for age, blast ratio of bone marrow and FAB classification. The median time (days) of neutrophil count less than 0.5×10(9)/L in IDA 8 mg/m(2) group, IDA 10 mg/m(2) group and IDA 12 mg/m(2) group were 14 (11-18) , 15 (11-20) and 18 (14-22) , respectively (=0.012) and of platelet count lower than 20×10(9)/L were 14 (7-17) , 15 (11-20) and 17 (15-21) , respectively (=0.001) . The incidences of lung infection in the three groups were 9.8%, 13.5% and 25.2%, respectively (<0.001) . For young adult patients (aged 18-60 years) with AML in China, intensifying induction therapy with idarubicin 10 mg/m(2) is clinically superior to IDA 8 mg/m(2) and IDA 12 mg/m(2) in favorable intermediate AML subgroup. However, idarubicin 12 mg/m(2) is more suitable to adverse AML subgroup.

We report a randomized prospective phase 3 study, designed to evaluate the efficacy and tolerability of idarubicin plus busulfan and cyclophosphamide (IDA-BuCy) versus BuCy in autologous hematopoietic stem-cell transplantation (auto-HSCT) for intermediate-risk acute myeloid leukemia (IR-AML) patients in first complete remission (CR1). One hundred and fifty-four patients were enrolled and randomized to receive IDA-BuCy (IDA 15 mg/m2/day on days -12 to -10, Bu 3.2 mg/kg/day on days -7 to -4, and Cy 60 mg/kg/day on days -3 to -2) or BuCy.

Objectives: The aims of this study were to evaluate a novel induction regimen composed of idarubicin (IDA), cytarabine (Ara-C) and cladribine (IAC regimen) for acute myeloid leukemia (AML) patients, and to identify the prognostic factors affecting treatment outcomes.
Methods: The clinical data of 27 untreated AML patients who received the IAC regimen as primary induction therapy in our hospital between April and November 2014 were analyzed retrospectively. The treatment outcomes of the IAC regimen were compared with two IA (IDA + Ara-C) regimens (IDA 10 mg/m² and IDA 12 mg/m²) in a pair-matched analysis.

Objective: To compare the efficacy and toxicity of 10 mg/m² or 8 mg/m² idarubicin (Ida) combined with cytarabine (IA"3+7"regimen) as induction chemotherapy for adult patients with newly diagnosed acute myeloid leukemia (AML).
Methods: From June 2004 to October 2013, 335 adult AML (non acute promyelocytic leukemia) patients receiving the IA regimen as induction chemotherapy were enrolled, including 198 cases with 10 mg/m² Ida and 137 cases with 8 mg/m² Ida for 3 days. We compared the hematologic response, hematologic side effects and prognosis between the two regimens.

Relapse remains the leading cause of death in patients with acute myeloid leukaemia (AML). Relatively few new chemotherapy agents have been proven to be effective in this population. We report on a Phase 2 clinical trial using the novel combination of 2-chlorodeoxyadenosine (2-CDA) (8 mg/m² per d x 5 d) plus idarubicin (Ida) (10 mg/m² per d x 3 d).

Aim: To analyze the results of idarubicin (IDA)- versus etoposide (VP16)-intensified myeloablative conditioning regimen in allogeneic hematopoietic stem cell transplantation (allo-SCT) for high-risk acute leukemia.
Methods: From January 2005 to June 2008, 48 consecutive patients (male: n=29; median age: 30 years, range 14-51 years) with high-risk acute leukemia underwent allo-SCT following an IDA- or VP16-intensified conditioning regimen. The conditioning regimens were modified BUCY2 (busulfan+cyclophosphamide) consisting of IDA (15 mg/m2 per day, days -12 to -10) or VP16 (25 mg/kg per day, days -3 to -2) and CY/TBI (cyclophosphamide/total body irradiation) intensified with IDA (15 mg/m2 per day, days -6 to -5) or VP16 (25 mg/kg per day, days -3 to -2) for acute myeloid leukemia and acute lymphoblastic leukemia, respectively.
