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...

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 evaluate the outcomes of retinoblastoma (RB) based on the 8th edition of the American Joint Committee on Cancer (AJCC) pathological classification in a global cohort of patients. Design: Retrospective, multicenter, intercontinental, collaborative study. Participants: A total of 1411 patients. Intervention: Primary enucleation with or without adjuvant chemotherapy or radiotherapy. Main Outcome Measures: Orbital tumor recurrence, tumor-related metastasis, and tumor-related death. Results: According to the 8th edition AJCC pathological classification, 645 eyes (46%) belonged to pathological T (pT)1, 164 (11%) to pT2, 493 (35%) to pT3, and 109 (8%) to pT4 categories. At a mean follow-up of 38 months (median, 35 months; < 1–149 months), orbital tumor recurrence was seen in 8 (1%), 5 (3%), 22 (4%), and 25 (23%) of pT1, pT2, pT3, and pT4 (P < 0.001) categories, respectively;...

Purpose: To evaluate high-risk histopathological features following primary enucleation of eyes with retinoblastoma and assess the patient outcomes across continents. Methods: A retrospective study of 1,426 primarily enucleated retinoblastoma eyes from five continents. Results: Of all, 923 (65%) were from Asia (AS), 27 (2%) from Australia (AUS), 120 (8%) from Europe (EUR), 162 (11%) from North America (NA), and 194 (14%) from South America (SA). Based on the continent (AS vs. AUS vs. EUR vs. NA vs. SA), the histopathological features included massive choroidal invasion (31% vs. 7% vs. 13% vs. 19% vs. 27%, P = 0.001), postlaminar optic nerve invasion (27% vs. 0% vs. 16% vs. 21% vs. 19%, P = 0.0006), scleral infiltration (5% vs. 0% vs. 4% vs. 2% vs. 7%, P = 0.13), and microscopic extrascleral infiltration (4% vs. 0% vs. <1% vs. <1% vs. 4%, P = 0.68). Adjuvant chemotherapy with/withou...
