title: Therapy related acute non-lymphocytic leukemia: report of 4 cases.
abstract: Four cases of acute myelodysplastic-non-lymphocytic leukemia secondary to cytotoxic agents were reported. Primary diseases were breast cancer (1 patient), ovarian cancer (2 patients) and multiple myeloma (1 patient). All except one (with multiple myeloma) were in clinical remission of their primary diseases. Common cytotoxic agent used was melphalan. Median total drug dose and median latent period from diagnosis of primary diseases were 1299 mg and 63 months respectively. None with the exception of one received specific treatment. All died except one who is in a very poor condition. Survival from the diagnosis of hematologic diseases ranged from 3-9 months. Clinical features, cytogenetic findings, pathogenetic mechanism and risk of the disease were briefly discussed.
