All trans retinoic acid has shown a remarkable effectiveness in acute promyelocytic leukemia. These results have encouraged studies of treatment with ATRA in other acute myeloid leukemia subtypes. In order to evaluate toxicity and antileukemic efficacy of all ATRA in patients with relapsed or refractory non promyelocytic AML, 95 patients (median age, 58 years; range, 20 to 80 years), with unclassified AML according to the FAB classification or secondary AML at diagnosis, or refractory or relapsing AML, received induction therapy with Idarubicin, 10 mg/m(2)/day, for 3 days and cytarabine, 1000 mg/m(2)/12 h, for 6 days, alone or combined, on a randomized basis, with ATRA, 45 mg/m(2)/day, from day 1 to complete remission. Patients in CR received maintenance therapy with 6 monthly courses combining Ida, 10 mg/m(2)/day, intravenously, on day 1 with Ara-C100 mg/m(2)/day, subcutaneously, from day 1 to day 5. Results were evaluated after one induction course. Overall 54 patients (57%, 26 wi...

The purpose of our study was (i) to evaluate the impact of all-trans retinoic acid (ATRA) given as adjunct to chemotherapy and (ii) to compare second consolidation vs maintenance therapy in elderly patients with acute myeloid leukemia (AML). A total of 242 patients aged >or=61 years (median, 66.6 years) with AML were randomly assigned to ATRA beginning on day +3 after the initiation of chemotherapy (ATRA-arm, n=122) or no ATRA (standard-arm, n=120) in combination with induction and first consolidation therapy. A total of 61 patients in complete remission (CR) were randomly assigned to second intense consolidation (n=31) or 1-year oral maintenance therapy (n=30). After induction therapy the intention-to-treat analysis revealed a significant difference in CR rates between the ATRA- and the standard-arm (52 vs 39%; P=0.05). Event-free (EFS) and overall survival (OS) were significantly better in the ATRA-compared to the standard-arm (P=0.03 and 0.01, respectively). OS after second ra...

The aim of this clinical trial was to evaluate the impact of all-trans retinoic acid (ATRA) in combination with chemotherapy and to assess the NPM1 status as biomarker for ATRA therapy in younger adult patients (18-60 years) with acute myeloid leukemia (AML). Patients were randomized for intensive chemotherapy with or without open-label ATRA (45 mg/m(2), days 6-8; 15 mg/m(2), days 9-21). Two cycles of induction therapy were followed by risk-adapted consolidation with high-dose cytarabine or allogeneic hematopoietic cell transplantation. Due to the open label character of the study, analysis was performed on an intention-to-treat (ITT) and a per-protocol (PP) basis. One thousand one hundred patients were randomized (556, STANDARD; 544, ATRA) with 38 patients treated vice versa. Median follow-up for survival was 5.2 years. ITT analyses revealed no difference between ATRA and STANDARD for the total cohort and for the subset of NPM1-mutated AML with respect to event-free (EFS; p = 0.93,...
