lüll Advances in the management of acute promyelocytic leukemia and other hematologic malignancies with arsenic trioxide Slack JL; Waxman S; Tricot G; Tallman MS; Bloomfield CDOncologist 2002[]; 7 Suppl 1 (ä): 1-13Acute promyelocytic leukemia (APL), once considered the most devastating subtype of acute myeloid leukemia, is now the most treatable of all subtypes as a result of intensive research into its molecular pathogenesis. This research has led to a rational approach to treatment in which the use of the differentiating agent all-trans-retinoic acid (ATRA) has proven to be effective first-line treatment for inducing complete remission. Arsenic trioxide (ATO) is currently used to treat relapsed disease, further enhancing survival rates in a patient population for which limited salvage options exist. This review discusses the molecular mechanisms responsible for development of APL and the evolution of treatment options over the last three decades, including the major advances using ATRA and ATO in the last 12 years. The mechanism of action of ATO is also described in view of this agent's potential for broader therapeutic application in a variety of hematologic malignancies.|Antineoplastic Agents/*therapeutic use[MESH]|Arsenic Trioxide[MESH]|Arsenicals/administration & dosage/*therapeutic use[MESH]|Clinical Trials as Topic[MESH]|Hematologic Neoplasms/*drug therapy[MESH]|Humans[MESH]|Leukemia, Promyelocytic, Acute/*drug therapy[MESH]|Multiple Myeloma/drug therapy[MESH]|Myelodysplastic Syndromes/drug therapy[MESH]|Oxides/administration & dosage/*therapeutic use[MESH]|Recurrence[MESH]|Remission Induction[MESH]|Survival Analysis[MESH]|Treatment Outcome[MESH]|Tretinoin/therapeutic use[MESH] |
