• To determine the efficacy of secondary salvage intravenous chemotherapy (IVC) for refractory/recurrent retinoblastoma. Retrospective, nonrandomized interventional case series of 41 eyes of 33 patients with recurrent retinoblastoma. Of the 33 patients, mean age at the time of commencement of salvage IVC was 5 years (median, 5 years; range, 2-8 years). At presentation, recurrent retinoblastoma in 41 eyes of 33 patients was classified by the International Classification of Retinoblastoma as Group B (n = 7; 17%), Group C (n = 3; 7%), Group D (n = 16; 39%), and Group E (n = 15; 37%). All patients received 6 cycles of IVC as primary treatment. The indication for secondary salvage IVC with focal treatment included recurrent solid tumor (n = 36; 88%), subretinal seeds (n = 22; 54%), or persistent solid tumor (n = 2; 5%). Mean number of cycles of salvage IVC were 8 (median, 6; range, 6-18). Over a mean follow-up period of 43 months (median, 43 months; range, 12-96 months) after completion of salvage IVC, globe salvage was achieved in 22 (54%) eyes, 1 (3%) patient had histopathology-proven bone metastasis, and 1 (3%) patient died because of presumed metastasis. Secondary salvage IVC with appropriate focal treatment allows globe salvage in 54% eyes with refractory/recurrent retinoblastoma and thus serves as an alternative to intraarterial chemotherapy or enucleation.
