• Retinoblastoma is curable in industrialized countries. However, it is associated with mortality in resource-poor nations due to disparities and poor access to eye care. Aim was to determine the relationships between patient-related factors and clinical outcomes of Retinoblastoma management in a tertiary hospital in Nigeria. This was a retrospective study of all children who were diagnosed and treated for Retinoblastoma from January 2017 through December 2022. Information obtained from their records included biosocioeconomic data, symptoms, lag time from initial symptoms, staging, treatment and outcome (dead or alive). Fifty-three patients, aged 6 to 88 months on first hospital presentation were recruited. There were 29(54.7%) females and 20(37.7%) patients died. Parental low socioeconomic class, rural residence and poor nutrition occurred more in those that survived, though not significantly (p>0.05). Median(interquartile) age at diagnosis [24(18-36) months, p=0.005] and lag time [13(6-20) months, p=0.274] were low in the survived group. Bilateral Retinoblastoma (20.8%,p=0.002), brain metastasis (22.6%,p<0.001), IRSS IV (18.9%,p=0.01) and relapse (34%,p<0.001) occurred more among the patients that died. The overall survival (OS) was 22(11.77-32.23) months with 1-year OS of 63%. Treatment with only chemotherapy [HR 4.76(95%CI:1.726-13.128)], incomplete chemotherapy [HR 5.61(95%CI:1.271-24.741)], relapse [HR 5.98(95%CI:1.376-25.983)] and eye surgery after 3 chemotherapy cycles [HR 8.22(95%CI:1.087-62.239)] were predictors of mortality. Early presentation of retinoblastoma especially of advanced and bilateral disease may lead to improved survival if chemotherapy and eye surgery are appropriately performed. Routine screening and immediate referral of retinoblastoma particularly in rural areas are recommended.
