Patient survival
Death occurred in 29 cases (16.6%). The probability of survival was
56% at 36 months. The median survival time was 3.7 months
(interquartile range [IQR]: 2.1-7.3). The critical period
corresponds to the first six months with a death rate of 36.6%. The
main predictors of mortality were the progressive form of retinoblastoma
and the refusal of chemotherapy (Table 5).
