title: [Epidemiology and prognosis of childhood cancers in Dakar, Senegal].
abstract: Childhood cancer has often been considered as a problem mainly affecting industrialized countries. In reality more than half of cases occur in developing countries where management and diagnosis are major issues. This retrospective study includes 130 children (0.3% of admissions) between the ages of 0 and 15 years hospitalized for malignant disease at the Principal Hospital in Dakar, Senegal between January 1, 1990 and December 31, 2000. Mean age was 97 months and M/F sex ratio was 1.2. Mean delay for admission was 3 months. The five most frequent cancers, accounting for 75% of cases, were leukemia (n = 28), lymphoma (n = 21), nephroblastoma (n = 21), retinoblastoma (n = 16) and osteochondrosarcoma (n = 10). Treatment was completed in 18% of cases. Half of patient were lost from follow-up. The cure rate was 10% overall and 50% for patients receiving complete treatment. The highest cure rate was achieved for nephroblastoma, i.e., 58% of cases treated. Management of childhood cancer in Africa is confronted with numerous problems, namely, paucity of specialized staff, absence of expert centers, shortage of anticancer drugs, lack of financial resources, and delay in treatment. These factors associated with frequent malnutrition and recurrent infectious diseases, greatly lower cure rates in comparison with industrialized countries.
