Background and objective: The growing use of antineoplastic treatments has led to an increase in the incidence of therapy-related leukemias (TRL). The objective was to describe the characteristics of TRL. Patients and methods: Twenty-three cases of TRL were registered. Chemotherapeutic agents used for the first tumor, time interval, clinical and biological characteristics, treatment and prognosis of the TRL were analyzed. Results: Median age was 61 years. Cytotoxic agents used in previous neoplasm consisted of alkylating agents (17 patients), inhibitors of DNA topoisomerase II (14), antitubulin agents (12), radiotherapy (9, in 6 with radiotherapy) and antimetabolites (6). Median time from diagnosis of the first neoplasm to TRL was 3 years (range 1.2-15.8). Thirteen patients received intensive chemotherapy [with stem cell transplantation (SCT) in 3] and the other 10 received symptomatic treatment (median survival 3 years versus 0.079 years, P = 0.004). Conclusions: In this study, TRL were associated with exposure to alkylating agents, antitubulin agents and topoisomerase II inhibitors. Response to treatment and prognosis were poor, although chemotherapy and SCT may prolong survival. © 2010 Elsevier Españ a, S.L. Todos los derechos reservados.
