The problem of pediatric malignancies in the developing world.

In industralized countries, 70 to 80% of children with cancer can be cured by expensive interdisciplinary teamwork and by cooperation on the national or international level. As a result of poor socio-economic conditions, worldwide, less than 20% of the approximately 185,000 children developing cancer each year get adequate treatment. This is also true for 14 to 15 million children dying each year of diarrhea and infections, but while this number is decreasing, the number of children with cancer is increasing. In "middle income" developing countries, cancer is now a leading cause of death for children between 5 and 15 years of age. The "geography" of pediatric cancer reveals complex interactions between environment, lifestyle, and carcinogenesis. The "mapping" of pediatric cancer is far from complete, and the investigation of carcinogenetic interactions has barely started. A great challenge is the planning of pediatric oncology in developing countries. The goals are to improve the access to treatment and treatment results. Even if pediatric oncology has a low priority, the institution, in each country or large province, of at least one pediatric cancer unit may improve not only cancer treatment but medical care in general. By promoting education, organizing meetings, and setting minimum standards for training and care, international organizations can contribute to the development of pediatric oncology worldwide.
