    Résumé

    Treatment combining ATRA and chemotherapy (CT) has improved the outcome of APL patients, by comparison with CT alone. ATRA syndrome is a life-threatening complication of ATRA treatment whose prophylaxis remains somewhat controversial. In APL93 trial, newly diagnosed APL patients ≤65 years and with initial WBC counts below 5000/mm3 were randomized between ATRA until CR achievement followed by CT (ATRA → CT) and-ATRA with early addition of CT, on day 3 of ATRA treatment (ATRA + CT). The incidence of ATRA syndrome in the ATRA → CT arm was 18% (22/122) as compared to 9.2% (17/184) in the ATRA + CT arm (P = 0.035). In the ATRA → CT arm, three (2.5%) patients died from ATRA syndrome, as compared to one (0.5%) in the ATRA + CT group. Early addition of chemotherapy to ATRA in newly diagnosed APL with low WBC counts significantly reduced the incidence of ATRA syndrome.
