Popis: Background: Childhood acute lymphoblastic leukemia (ALL) represents the largest group of pediatric malignancies with long-term survival rates of more than 80% achieved in developed countries. Epidemiological data and survival rates of childhood ALL in Lithuania were lacking. Therefore, the aim of this study was to analyze the population-based long-term treatment results of childhood ALL in Lithuania during 1992–2012. Materials and methods: Data of all 459 children with T-lineage and B-cell precursor ALL treated in Lithuania from 1992 to 2012 were collected and analyzed. Results were compared among four time-periods: 1992–1996 (N = 132), 1997–2002 (N = 136), 2003–2008 (N = 109) and 2009–2012 (N = 82). Results: The incidence of childhood ALL in Lithuania was 3.2–3.6 cases per 100 000 children per year during the study period. Five-year probability of event-free survival increased from 50% ± 4% in 1992–1996 to 71% ± 4% in 2003–2008 (P
