[Evaluation of 58 patients with acute leukemia]

We made a retrospective study of 44 patients with acute non-lymphocytic leukemia (ANLL) and 14 patients with acute lymphocytic leukemia (ALL) admitted to our hospital from September 1984 to May 1991. The complete remission (CR) rate of ANLL was 90.9%, against 85.7% for ALL. The 5-year survival of ANLL was 50.7%, and that of ANLL under age 60 years was 70.3%. The 2-year median survival of ALL was 35.1%. These results were obtained with response-oriented individualized therapy, and intensive chemotherapy with a view to eradication of residual leukemic cells. Eight elderly patients with ANLL were treated with cytosine arabinoside in low doses. Complete remission was achieved in 6 patients, but these cases relapsed. These treatments should be reconsidered for long CR duration. Our schedules of response-oriented individualized therapy were too flexible to apply at another institute so they should be arranged for general application.
