Clinical outcome in acute myeloid leukemia (AML) is unsatisfactory. One strategy to augment cytotoxicity is TST. All-trans retinoic acid (ATRA) down-regulates bcl-2 expression and heightens AML sensitivity to cytosine arabinoside (ara-C)-induced apoptosis in vitro. We designed a trial of ATRA plus ara-C-based TST in an attempt to enhance drug-induced apoptosis and clinical outcome. Between January 1998 and February 2000, 63 patients received induction TST (oral ATRA days 1-6, ara-C and idarubicin days 2-4, VP-16 days 9-11) followed by consolidation TST (ATRA, ara-C and idarubicin followed by a second ara-C infusion days 11-13). Complete remission (CR) was 60%, with higher rates for patients of <60 years (79%), de novo AML (70%), and non-adverse cytogenetics (81%). Median disease-free survival (DFS) for CR patients was 11.2 months (32% at 3+ years). For patients <60 years with de novo AML and non-adverse cytogenetics who underwent two-cycle TST, DFS was 67% at 3+ years. However, patients of age equal to 60 years and those with poor-risk disease features still have poor CR and DFS, despite the addition of ATRA. (C) 2002 Elsevier Science Ltd. All rights reserved.
