| Popis: | Background The survival of retinoblastoma in less-developed countries (LDCs) and the impact of socioeconomic variables on survival are not widely available in the literature. Methods A systematic review of publications from LDCs was performed. Articles were from multiple databases and written in seven languages. Results were correlated with socioeconomic indicators. Lower-income countries (LICs) and middle-income countries (MICs) were included in our analyses. Results An analysis of 164 publications including 14 800 patients from 48 LDCs was performed. Twenty-six per cent of the papers were written in languages other than English. Estimated survival in LICs was 40% (range, 23–70%); in lower MICs, 77% (range, 60–92%) and in upper MICs, 79% (range, 54–93%; p=0.001).Significant differences were also found in the occurrence of metastasis: in LICs, 32% (range, 12–45); in lower MICs, 12% (range, 3–31) and in upper MICs, 9.5% (range, 3–24; p=0.04). On multivariate analysis, physician density and human development index were significantly associated with survival and metastasis. Maternal mortality rate and per capita health expenditure were significantly associated with treatment refusal. Conclusions Important information from LDCs is not always available in English or in major databases. Indicators of socioeconomic development and maternal and infant health were related with outcome. |
