title: [The risk of the occurrence of acute nonlymphoblastic leukemia in patients with malignant neoplasms undergoing radio- and chemotherapy].
abstract: The paper discusses the results of an epidemiologic case-control study dealing with the risk of development of acute nonlymphoblastic leukemia in patients treated with radio- or chemotherapy. Out of 165 patients with primary multiple metachronous tumors, primary Hodgkin's disease, lymphosarcoma and breast, ovarian and testicular cancer, 18 developed secondary acute nonlymphoblastic leukemia; in 13, the primary tumor had been Hodgkin's disease, in 4--breast cancer and in one--testicular cancer. Relative risk (RR) of acute nonlymphoblastic leukemia proved higher in patients who had undergone radiation (RR = 6.4) or chemotherapy (RR = 1.9). Combination of those two procedures carried a higher risk, too (RR = 5.9). Relative risk of acute nonlymphoblastic leukemia proved the highest in patients treated with adriamycin (11.3) and nitrogen mustard (9.9) and much lower for cyclophosphamide (RR = 1.5).
