title: [Results of induction therapy in newly diagnosed acute myeloid leukemias in study 911 at the Institute of Hematology and Blood Transfusion].
abstract: Thirty-seven patients with de novo acute myeloid leukemias were admitted to the Institute of Hematology and Blood Transfusion in Prague in February 1991-December 1993. Their age was 18-85 years with a median of 46 years. Two patients died on the day of admission, chemotherapy was initiated in 35 patients. Altogether 27 patients (77%) achieved complete remission (CR), i.e. 18 (81%) of 22 patients younger than 55 years and 9 (70%) of 13 patients older than 55 years. Only 7 (35%) of 20 patients achieved CR after a single therapy course 3/7 consisting of 3 doses of daunorubicin 45 mg/m2 on days 1, 3, 5 and cytosine arabinoside 150-200 mg/m2 every 12 hours for 7 days. However, 8 (61%) of 13 patients achieved CR after a single treatment course 4/7 with 4 doses of daunorubicin 45 mg/m2 on days 1, 3, 5, 7 and identical doses of cytosine arabinoside as in the 3/7 treatment. We used the course with 10 high-doses of cytosine arabinoside 2000 mg/m2 every 12 hours and daunorubicin 45 mg/m2 on days 4 and 5 (treatment HDAC/DNR) as the 1st, 2nd or 3rd induction therapy in 12 patients and 9 (75%) of them achieved CR. The treatment was associated with a high toxicity. An intensified therapy 3/7h similar to the 3/7 one but with the doubled dose of cytosine arabinoside 300-400 mg/m2 on days 5-7 was given to 5 patients as the 2nd induction but it did not improve the CR rate and it was associated with a high toxicity similar to the HDAC/DNR therapy.(ABSTRACT TRUNCATED AT 250 WORDS)
