Neuroblastoma in Africa: A Survey by the Franco-African Pediatric Oncology Group.
Journal of Global Oncology 2016 August
PURPOSE: Neuroblastoma is a sympathoadrenal lineage neural crest-derived tumor. It is the third most common childhood malignancy in the Western world. Studies from the United States show that black patients with neuroblastoma have a greater proportion of high-risk neuroblastoma with poorer prognosis compared with white patients. In Africa, there are few published data on the epidemiology and management of neuroblastoma. The primary aim of this study was to assess the diagnostic and therapeutic resources available for the management of neuroblastoma within the Franco-African Pediatric Oncology Group (GFAOP).
METHODS: A survey was conducted in the pediatric oncology centers of the GFAOP. Participating GFAOP centers were Abidjan, Algiers, Bamako, Dakar, Lubumbashi, Lomé, Ouagadougou, Rabat, Tananarive Antananarivo, and Tunis. Questionnaires were sent out by e-mail to the principal investigators at each participating GFAOP center in December 2013.
RESULTS: Ten (62%) of 16 GFAOP centers responded to the questionnaire. Neuroblastoma represented only 3% to 5% of childhood cancers in the sub-Saharan African centers, with the exception of Antananarivo, where it represented 7.5%. In contrast, in the northern African centers of Tunis, Rabat, and Algiers, neuroblastoma accounted for 30%,10%, and 7% of childhood cancer, respectively. At initial diagnosis, 50% to 80% of patients had metastatic neuroblastoma in eight of 10 centers.
CONCLUSION: Based on this survey, neuroblastoma seems to be less common in sub-Saharan Africa. The proportion of patients with metastatic neuroblastoma seems to be higher than reported in Western countries.
