9526 Background: Despite dramatic advances in curing childhood cancer in developed countries, most children with cancer live in low-income countries, where misdiagnosis, late diagnosis, lack of access to treatment and abandonment of treatment hinder progress. Methods: In 2004 the International Union against Cancer and sanofi-aventis initiated a campaign to improve childhood cancer care in developing countries through grants for local projects (up to 50,000 euros/year each), a survey of childhood cancer care (conducted by the public health consulting firm Sanisphere), and lobbying to increase political support. The projects focus on professional education, improved access to care, pain management, and psychosocial/educational support. Results: During 2006, 14 pilot projects in Bangladesh, Egypt, Honduras, Morocco, Philippines, Senegal, Tanzania, Ukraine, Venezuela, and Vietnam were selected on the basis of feasibility, expected benefit, sustainability, and potential to serve as models. Only eight countries had pediatric hematology/oncology units, ranging from 20 (Tanzania) to 350 (Egypt) beds. These units manage 100 (Senegal) to 1,000 (Bangladesh) children with cancer per year (a small fraction of actual cases in these countries). One-year outcome analysis showed that various short-term objectives were met, including improved patient care infrastructure, public and professional education, earlier detection, improved access to care, the introduction of psychosocial support, decreased abandonment and better follow up. On the basis of these results, 12 additional projects have been funded in Bolivia, Indonesia, Kenya, Mali, Peru and Romania. Conclusions: Relatively small investments, accompanied by external mentoring, can help build sustainable capacity for the diagnosis and care of children with cancer in selected institutions in developing countries.
