Population and sampling
The study involved children with retinoblastoma aged 0 to 17 who were
consecutively admitted with retinoblastoma in the selected centers
during the period from January 1, 2013, to December 31, 2015. Children
whose records did not contain essential information (sex, age,
laterality, acceptance of treatment, date of the last news or death or
end of treatment) were excluded from the analysis.
The children were included in the study after obtaining written or oral
informed consent from their parents (caregivers), in accordance with the
local recommendations and the guidelines of the
GFAOP15. This study received approval from the ethics
committees of the University of Lubumbashi and the Felix Houphouët
Boigny University of the Ivory Coast.
