Introduction Leukemia is the most common hematological neoplasm, their incidence was increased in different regions of the world. Bolivia is experiencing the phenomenon of "epidemiological transition", from a high incidence of infectious diseases to an increasing prevalence of oncological diseases. This paper describes the epidemiological features of leukemia in Bolivia. Methods Patients were grouped into two groups: The pediatric patients under 18 years and adult patients over 18 years and one day. We studied the diagnostic results and epidemiological data of 1473 samples of leukemia patients from different centers for oncohematologic disease of Bolivia, in dates between January 1999 to May 2012. All the samples were tested with morphologic and immunophenotypical studies. The diagnoses of Chronic Myeloid Leukemia and Acute Promyelocitic Leukemia (AML-M3) were confirmed with biomolecular studies. Results Of 1473 patients with leukemia, 896 (61%) were pediatric patients and 577 (39%) were adults patients. In pediatric patients were 47% girls and 53% were children. The distribution according to the diagnosis was the following: acute lymphoblastic leukemia 706 (79%), acute myeloblastic leukemia 172 (19%) and chronic myeloid leukemia 18 (2%). In adult patients 43% were women and 57% were male. The Distribution according to the diagnosis was the following: acute lymphoblastic leukemia 188 (33%), acute myeloblastic leukemia 176 (30%), chronic lymphocytic leukemia 31 (5%) and chronic myeloid leukemia 182 (32%). Conclusion The results obtained showed different epidemiological characteristics, probably due to the structure multiethnic, multicultural and lower life expectancy in relation to other countries.
