PURPOSE: To examine the outcome of salvage intra-arterial chemotherapy (IAC) for patients with recurrent retinoblastoma after the initial course of IAC and determine the factors influencing clinical outcome.
METHODS: A total of 73 eyes of 71 patients with recurrent retinoblastoma undergoing salvage IAC after initial successfully IAC between May 2014 and May 2019 were retrospectively reviewed for clinical outcomes. Ocular survival and progression-free survival were used to examine the efficacy of salvage IAC. The factors influencing clinical outcomes were determined using univariate and multivariate analyses.
RESULTS: The salvage IAC was delivered at mean 9.4 months (median 7, range 2.1-38.3 months) following the last cycle of initial IAC. 86.5% (64/73) eyes relapsed 16 months after the initial IAC. After the salvage IAC, 57 eyes (78.1%) were salvaged, and no further-line therapies were required for 36 eyes (49.3%). The 2-year Kaplan-Meier ocular survival and progression-free survival estimates after salvage IAC were 66.4% (95% CI, 31.5-42.1%) and 38.2% (95% CI, 17.8-28.8%), respectively. Univariate and multivariate analyses showed that the ocular survival and progression-free survival after salvage IAC were significantly associated with the history of vitreous seeds (p = 0.02 and p = 0.03, respectively).
CONCLUSION: Salvage IAC is effective for the management of recurrent retinoblastoma after the initial successful IAC. Eyes with a history of vitreous seeds in the course of the disease are more likely to relapse and with worse ocular survival. A close follow-up strategy is imperative to treat the recurrent tumour after salvage IAC.
