Özet

Purpose To evaluate clinical outcomes and enucleation rates after intravitreal melphalan (IVM) alone and after IVM combined with intravitreal topotecan (IVT) for the treatment of vitreous disease, and to a lesser extent subretinal and retrohyaloid seeds, in patients with retinoblastoma. Study design A retrospective analysis of 77 eyes of 72 consecutive patients. Methods Demographic data, classification of tumors, seed type (dust, sphere or cloud) before injection and at the end of follow-up, injection type (IVM or IVM+IVT), doses of IVM and IVT, number of injections, follow-up time, enucleation status and side effects were recorded. Cox regression analysis and log-rank test for Kaplan-Meier curves were performed. Results Of 77 eyes, 40 received IVM alone (group 1) and 37 received IVM+IVT (group 2). Enucleation rates were 62.5% (n=25) in group 1 and 10.8% (n=4) in group 2 (p=0.001). Median eye survival was 23.6 months in group 1 and 25.6 months in group 2. Mantel-Cox test revealed statistically significant differences between Kaplan-Meier curves of group 1 and 2 (p=0.022). Multiple Cox regression analysis showed a significantly elevated enucleation rate associated with: IVM only treatment group (p=0.019) and pre-injection cloud type of seeding (p=0.014). Conclusion The combined use of intravitreal melphalan and topotecan provides significantly better results in terms of avoiding enucleation and vitreal and subretinal seed control.
