5-Aza-2′-deoxycytidine combined with either amsacrine or idarubicin has been applied in a treatment protocol for patients with a relapse of acute myeloid or lymphocytic leukemia. Sixty-three patients received 5-Aza-2′-deoxycytidine 125 mg/m² as a 6 h infusion every 12 h for 6 days in combination with either amsacrine 120 mg/m² as a 1 h infusion on days 6 and 7 (n = 30) or idarubicin 12 mg/m² as a 15 mm infusion on days 5, 6 and 7 (n = 33). Twenty-three patients (36.5%) obtained a complete remission (CR); eight of 30 patients treated with amsacrine and 15 of 33 treated with idarubicin. Patients with an interval of more than 1 year between initial diagnosis and start of the protocol achieved CR in 51.4%, compared to 15.4% for patients with an interval of less than 1 year. Patients with normal cytogenetics had a higher CR rate (61%) than those with abnormal cytogenetic findings (15.8%). Digestive tract and hematologic toxicity was prolonged, compared to standard induction schedules. Median disease-free survival was approximately 8 months, with only 20% of patients staying in remission for more than 1 year. 5-Aza-2′-deoxycytidine is a good antileukernic agent with considerable toxicity. Current results merit further investigations in previously untreated leukemia. [ABSTRACT FROM AUTHOR]
