Impact of Systemic Chemotherapy and Delayed Enucleation on Survival of Children with Advanced Intraocular Retinoblastoma

Abstract

We observed that pre-enucleation chemotherapy offered no survival benefit and timely enucleation minimized risk of metastatic death. Postenucleation chemotherapy improved survival of children with high-risk histopathology but was not useful for those with low-risk histopathology. These findings facilitate informed discussion on the risks and benefits of delayed enucleation, the use of systemic chemotherapy for trial salvage of eyes with advanced intraocular retinoblastoma, and the specific children who benefit from postenucleation chemotherapy.
