[Childhood cancer: a comparative analysis of incidence, mortality, and survival in Goiania (Brazil) and other countries]. 
Analysis of cancer incidence, mortality, and survival rates can yield geographic and temporal trends that are useful for planning and evaluating health interventions.  This article reviews cancer incidence and mortality rates and respective trends around the world in children under 15 years old, as well as their 5-year survival rates in developed and developing countries.  We conclude that even though increasing or stable childhood cancer incidence rates and decreasing mortality rates have been observed in developed countries, the trends remain unknown in developing countries.  Data from the city of Goiania, Brazil, show stable childhood cancer incidence and mortality rates.  Five-year survival rates (48%) in Goiania are similar to those seen in underdeveloped regions and lower than those reported in developed countries (64-70%).
