Resumo

Purpose: The objective of this study was to compare outcomes after intravenous chemotherapy (IVC) versus intra-arterial chemotherapy (IAC) for unilateral retinoblastoma. Design: A retrospective comparative interventional case series. Methods: Patients with unilateral retinoblastoma managed with either IVC using vincristine, etoposide, and carboplatin or IAC using melphalan with or without topotecan with a minimum of 1-year follow-up were compared. The primary outcome measure was globe salvage. Results: Of 91 patients with unilateral retinoblastoma, IVC was employed in 42 (46%) cases and IAC in 49 (54%). By comparison (IVC vs IAC), patients in the IAC group had greater mean tumor diameter (14 vs 18 mm, P < 0.001) and thickness (7 vs 10 mm, P = 0.001), greater percentage-with active vitreous seeds (29% vs 55%, P = 0.01), and greater total retinal detachment (10% vs 43%, P < 0.001). There were no cases of group A in either treatment arm. Globe salvage was not significantly different in groups B, C, or E, but there was significantly improved globe salvage with IAC for groupD (48% vs 91%, P = 0.004). Control was significantly better with IAC for solid tumor (62% vs 92%, P = 0.002), subretinal seeds (31% vs 86%, P = 0.006), and vitreous seeds (25% vs 74%, P = 0.006). There were no patients with pinealoblastoma, second cancer, metastasis, or death in either group. Conclusions: For unilateral retinoblastoma, IAC provided significantly superior globe salvage compared with IVC for group D eyes. In addition, IAC provided significantly superior control for solid tumor, subretinal seeds, and vitreous seeds. (AU)
