    Abstract:
    We evaluated the effect of treatment by all-trans retinoic acid (ATRA) in 9 patients with acute promyelocytic leukemia (APL). Of 6 patients who had circulating leukemic blasts before treatment, 3 initially received ATRA alone but died of respiratory failure due to retinoic acid syndrome (RAS). High dose steroid therapy did not rescue RAS in these patients. Another 3 who were given intensive chemotherapy followed by ATRA and/or granulocyte colony-stimulating factor (G-CSF) achieved complete remission (CR). Of 3 patients without peripheral leukemic blasts before treatment, 1 received intensive chemotherapy followed by G-CSF and reached CR, 1 who had been previously given ATRA did not respond to ATRA, and 1 did not initially respond sufficiently to ATRA alone but responded dramatically to ATRA plus G-CSF. In the treatment of APL, appropriate combination of ATRA, G-CSF and chemotherapy should always be taken into consideration. In addition, RAS have to be carefully avoided when applying ATRA therapy in patients who have circulating leukemic blasts before treatment.
