N2 - Retinoblastoma (RB) is the most common intraocular pediatric malignancy. Advancements in intra-arterial chemotherapy (IAC) for treatment of RB have resulted in dramatic improvement in eye salvage rates. Data regarding IAC outcomes and associated hematologic toxicities are limited. The objective of this retrospective study was to analyze baseline characteristics, efficacy, and hematologic complications associated with IAC treatment in children with RB at a single international referral institution. Ninety-five sessions of IAC were performed in 28 patients. Mean age at RB diagnosis was 12.5 months (SD, 9.2 mo). Fourteen patients had bilateral RB. IAC agents included melphalan, carboplatin, and topotecan. The most common regimens were triple-agent IAC and single-agent melphalan (66.3% and 15.8%, respectively). Median number of IAC sessions was 3 (mean: 3.39, range: 1 to 9). Eye salvage rate was 83.7% with an overall survival rate of 100% at a median follow-up of 29 months (mean: 29.8 mo, range: 1 to 63 mo). A total of 26 patients (92.9%) experienced at least 1 hematologic toxicity during their treatment course Prevalence of neutropenia, anemia, and thrombocytopenia were 89.3%, 85.7%, and 25%, respectively. While IAC is effective in salvaging most eyes with advanced intraocular RB, over half of patients experienced clinically significant neutropenia and anemia. Clinicians should be vigilant in monitoring patients for IAC-related complications.
