Study framework
This study was conducted in three cities in the DRC (Lubumbashi, Bukavu, and Kinshasa) and one city in the Ivory Coast (Abidjan). These cities were chosen due to the participation of their pediatric oncology units as well as the ophthalmological center of Bukavu in a research collaboration within the framework of a program for early diagnosis and access to treatment of retinoblastoma in sub-Saharan Africa. The program was initiated by the Global Alliance Against Cancer (AMCC) in collaboration with the Franco-African Pediatric Oncology Group (GFAOP) and the Institut Curie, supported by the SANOFI ESPOIR foundation as part of its My Child Matters program14.
