Purpose: To compare the clinical outcomes of children with unilateral retinoblastoma (Rb) and high-risk histopathology features (HRHF) following upfront enucleation with/without adjuvant chemotherapy, and investigate cases locally considered non-HRHF but converted to a standardized HRHF definition. Design: Retrospective multinational clinical cohort study. Methods: Children with Rb who presented to 21 centers from 12 countries between 2011-2020, and underwent primary enucleation were recruited. Centers retrieved clinical data and were asked to report detailed histopathology findings, as well as indicate cases defined locally as high-risk. For analysis, only unilateral cases with standardized HRHF, defined as retrolaminar optic nerve invasion, massive choroidal invasion, scleral invasion, anterior-segment involvement, and/or combined nonmassive choroidal and prelaminar/laminar optic nerve...

Purpose: To assess histopathology and outcomes following primary enucleation of eyes with retinoblastoma presenting with neovascular glaucoma (NVG). Methods: This was an international multi-centre case series study across five continents. Retrospective review of patient charts was performed for all patients undergoing primary enucleation for retinoblastoma (n=1420) using a standardised data-collection spreadsheet. Clinical features, pathological grade, and outcomes were compared between NVG patients and those with an American Joint Commission on Cancer (AJCC) 8th edition clinical stage of cT2. High-risk histopathology was defined as AJCC 8th edition pathological stage ≥pT2b. Results: NVG was seen in 224/1420 (16%) patients. Mean age at presentation of those with NVG was 30 months (median 25, range 0-120 months) and 131(58%) patients had high-risk histopathology. The univariate logistic...
