[Treatment of acute myeloid leukemia in a special hematology unit].

Since 1984, 47 patients with untreated acute myeloid leukemia (AML) were hospitalized in a special hematology unit for aggressive chemotherapy. Complete remission was obtained in 68%, 15% died of complications of treatment (infections and bleeding) and 15% had refractory leukemia. The actuarial survival after 3 years for patients in remission was 43%. No patients with refractory leukemia lived more than 1 year. The actuarial remission at 3 years of 21 patients who received additional courses of aggressive chemotherapy (consolidation treatment) was 42%, as opposed to 11% in 11 patients who received maintenance treatment. The 47 patients received 108 courses of aggressive chemotherapy including 47 for induction of remission. During 86 courses (80%) the patients developed fever and in 33 blood cultures were positive; during 16 courses a fungal infection developed. The most common bacterial infection was by E. coli. During the first induction treatment 5 patients died of sepsis and 1 of cerebral hemorrhage. None died during consolidation therapy. During the year preceding the opening of the unit, 12 AML patients were treated on regular medical wards, and five (42%) achieved a complete remission, while 6 died of complications during the first course of induction chemotherapy. Our findings are in line with those of similar units, which indicates the importance of special nursing units for the treatment of acute leukemia.
