    Abstract:
    AIM: The aim of this study is to describe treatment outcomes and complications of selective intra-arterial chemotherapy (IAC) for intraocular retinoblastoma (RB). MATERIALS AND METHODS: A retrospective, interventional series of 10 eyes with RB which underwent IAC using melphalan (5 mg/7.5 mg) and topotecan (1 mg), or melphalan (5 mg/7.5 mg) alone. Treatment outcomes were evaluated in terms of tumor control, vitreous seeds (VS) and subretinal seeds (SRS) control, and globe salvage rates. RESULTS: Ten eyes of 10 patients underwent 38 IAC sessions (mean = 3.8; median = 4; range = 3-5 sessions). Following IAC, complete regression of main tumor was seen in 9 eyes (90%) and partial regression in 1 (10%). All four eyes with SRS showed complete regression (100%). Of 5 eyes with VS, 3 eyes (60%) showed complete regression, 1 eye (20%) showed relapse, while 1 eye (20%) showed no response. Globe salvage was achieved in 8 of 10 eyes (80%). Complications included transient ophthalmic artery narrowing (n = 2), branched retinal vein occlusion (n = 1), forehead skin pigmentation (n = 1), and vitreous hemorrhage (n = 2). There was no case of stroke, hemiplegia, metastasis, or death. Transient hematological changes included relative pancytopenia (n = 4), relative leukopenia (n = 5), and relative thrombocytopenia (n = 4). Mean follow-up was 26 months (median = 28, range = 13-36) from the initiation of first IAC. CONCLUSIONS: IAC is an effective therapy for globe preservation in eyes with intraocular RB, in the setting of a developing country like India. Larger studies with longer follow-up are required to validate these results.
