Abstract
Background and purposeIntra-arterial chemotherapy for retinoblastoma has been adopted as a first-line treatment option by numerous tertiary centers. The effect of intra-arterial chemotherapy on future rates of metastatic disease as well as on globe salvage in advanced eyes remains relatively unknown.MethodsA search of PubMED, MEDLINE, EMBASE, and Web of Science electronic databases was conducted from inception until January 2019 for studies with a minimum of 10 patients reporting outcomes and complications following intra-arterial chemotherapy for retinoblastoma.ResultsA total of 20 studies met the inclusion criteria for analysis, comprising 873 patients and 1467 eyes. Only one study was comparative; there was substantial heterogeneity in reported outcomes and several overlapping patient cohorts that were published. Across all studies, 174 of 1467 eyes were enucleated (11.8%). Metastatic disease occurred in 8 of 513 patients (1.6%). Globe salvage was achieved in 318 of 906 (35.6%) cases of advanced retinoblastoma. The most common ocular complication was retinal detachment, occurring in 23% of eyes, and the most common systemic complications were transient fever and nausea/vomiting.ConclusionsThere is a paucity of higher-level evidence with adequate follow-up surrounding the long-term safety of intra-arterial chemotherapy and effect on metastasis in retinoblastoma. Studies to date have been limited by short-term follow-up. Longitudinal prospective studies could provide greater insight into the ability of intra-arterial chemotherapy to reduce the risk of retinoblastoma metastasis.
