Abstract

Purpose

The goal of this study was to compare the efficacy of intraarterial chemotherapy (IAC) for retinoblastoma delivered via the ophthalmic artery (OA) division of the internal carotid artery (ICA) versus alternative branches of the external carotid artery (ECA).

Methods

We performed a retrospective chart review of patients receiving IAC for retinoblastoma at a single institution. Subjects were divided into three groups: those that received IAC solely through the OA branch of the ICA, those that initially received IAC through the OA branch of the ICA but were later switched to the ECA, and those that only received IAC through the ECA. The main outcomes compared included globe salvage rate and reduction in tumor thickness and size.

Results

A total of 30 eyes from 26 patients were included. A total of 91 (58%) sessions of IAC were performed through the OA division of the ICA and 65 (42%) were performed through branches of the ECA. Eleven eyes (37%) solely received IAC through the OA branch of the ICA, 16 eyes (53%) were converted to ECA treatment, and 3 eyes solely received IAC through branches of the ECA. Statistical analysis did not show any significant difference in globe salvage rate or reduction in tumor thickness and size.

Conclusion

The use of alternative approaches for IAC when the OA branch of the ICA catheterization is not feasible allows for safe continued delivery of highly effective IAC, leading to similar outcomes in terms of globe salvage and reduction in tumor size.
