Background: Cancer is relatively rare in childhood compared with later in life. In high-income countries, hematologic malignancies are the most common, then brain tumors and solid tumors. World age-standardized incidence rates in Ireland averaged 142 cases per million children per year, higher than European average and lower than US average. In Africa, distribution of childhood cancers is quite similar, commonest being Kaposi sarcoma (KS), Burkitt's lymphoma, retinoblastoma, leukemia and Hodgkin lymphomas (HL). Among adolescent in Zimbabwe, leukemia has highest incidence rates then osteosarcoma, non-Hodgkin lymphoma (NHL) and KS. Aim: To describe the incidence of cancer among children and adolescents in Kyadondo County, Uganda from 2009 to 2014 which is necessary for planning of cancer control programs. Methods: Descriptive cross-sectional study which involved review of data from Kampala Cancer Registry that gathers information on cancers diagnosed within Kyadondo County (formed by Kampala and Wakiso districts) and analyzed using STATA 13. From 2014 Uganda population census, Kyadondo County had a population of 3,523,910 (32.2% children and 10% adolescents). Study population was children (0-14 years) and adolescents (15-19 years) diagnosed with cancer from January 2009 to December 2014. Results: The spectrum of cancers in adolescents reflects a transition. Carcinomas which are so prevalent in adults occur but at lower frequencies in adolescents. Study results are comparable to others studies indicating that nephroblastoma and retinoblastoma were common among children and not adolescents. Leukaemia and lymphomas cut across both children and adolescents. Conclusion: The spectrum of cancers in adolescents reflects a transition. Carcinomas which are so prevalent in adults occur but at lower frequencies in adolescents. Study results indicate that nephroblastoma and retinoblastoma were common among children and not adolescents. New prospective studies should be done on children and adolescent cancers covering a wide population size. Leukaemia and lymphomas cut across both children and adolescents. National cancer registries should be set up.
