Abstract

Purpose : To assess the efficacy of intravitreal melphalan for treatment of vitreoretinal lymphoma (VRL).

Methods : Retrospective review of medical records of VRL patients treated with monthly intravitreal melphalan from September 2015 to November 2018.

Results : There were 12 eyes of 6 patients (3 male and 3 female) diagnosed with VRL at mean age of 70 years. At presentation, no patients were immunosuppressed, 1 patient had central nervous system (CNS) lymphoma, and 2 had systemic lymphoma in remission without treatment. Six eyes had had previous vitrectomy and 2 eyes had been treated with topical and oral steroids before referral. Eyes were treated with melphalan 10µg/0.05ml for a mean of 5 injections (median 6, range 1-14) as initial treatment. Mean number of injections to VRL regression was 3 (median 3, range 1-8). At mean follow-up of 12 months there was complete regression in 6 eyes (50%), partial regression in 3 eyes (25%), disease progression requiring change in treatment to intravitreal methotrexate with good tumor control in 2 eyes (17%), and 1 eye (8%) had recurrent disease after 2 months of complete regression without treatment requiring additional intravitreal melphalan injections. There was no difference in likelihood of achieving complete regression in eyes with sub-retinal pigment epithelial lymphoma (n=8, 67%) compared to eyes with vitreous lymphoma alone (n=4, 33%), (4 vs 2, p=0.3). At final follow-up, 1 eye (8%) was not receiving any form of treatment and 3 eyes (25%) were receiving ongoing monthly intravitreal melphalan without any other systemic treatment. Two patients (4 eyes, 33%) developed CNS lymphoma during the course of follow- up and were receiving ongoing monthly intravitreal melphalan and systemic methotrexate or combined methotrexate/rituximab for CNS lymphoma respectively. One patient (2 eyes, 17%) was not receiving any intravitreal treatment but systemic obinutuzumab (n=2, 17%) for treatment of skin lymphoma. There were no ocular complications from intraocular injection and a 2-line loss of Snellen visual acuity only occurred in 1 eye (8%) secondary to epiretinal membrane. All patients were alive at the last visit.

Conclusions : Monthly intravitreal injections of melphalan at a dose of 10µg/0.05 ml resulted in complete or partial control of VRL in 9 (75%) of the 12 treated eyes. Further studies are needed to determine the optimal dosage and interval between injections.
