“Retinoblastoma survival disparity”: The expanding horizon in developing countries

The patients' survival for the most common intraocular tumor in children, retinoblastoma, has a wide spectrum among the world countries. This study was conducted to provide an overview of the retinoblastoma survival disparity worldwide by discussing the trends of patients' survival, as well as recent advances in the management of retinoblastoma. The design of this study was literature review and commentary. Selected articles from PubMed (except one) including both developing and developed countries regarding the patients' survival in retinoblastoma were considered and reviewed critically. An analysis of 47 articles was performed. In conclusion, in spite of an obvious contrast of retinoblastoma survival disparity in the world, the expanding horizons in developing countries are promising and continuing on all fronts and results are hope-inspiring.
