N2 - PURPOSE: The aim of our study is to evaluate local tumour control rates, radiation side-effects, visual preservation and disease-free survival (DFS) of uveal melanoma (UM) patients treated with fractionated stereotactic radiotherapy (fSRT).METHODS: A retrospective study of UM patients, who were treated with fSRT (N = 189), was performed by the Rotterdam Ocular Melanoma Study group (ROMS), the Netherlands, between 1999 and 2014 with a follow-up of at least 5 years.RESULTS: The 1-, 3-, 5-, 10- and 15-year local tumour control rates were as follows: 99.4%, 92.8%, 92.2%, 89.3% and 89.3%, respectively. Cataract (67.8%) was the most common side-effect of fSRT followed by retinopathy (35.1%), maculopathy (23.8%), vitreous haemorrhage (20.1%), neovascular glaucoma (NVG) (20.0%) and optic neuropathy (12.4%). Patients with anterior located UMs developed cataract more frequently (p = 0.047, multivariable analysis). By multivariable analysis, significant factors for secondary enucleation were tumour recurrence (p < 0.001) and NVG (p < 0.001). In multivariable analysis, risk factors for a worse DFS were larger UM (p = 0.024) and tumours with subretinal fluid (SRF) at baseline (p = 0.038). The 5-year DFS was 77.0% and the best corrected visual acuity decreased significantly after treatment. After 5 years, 22.0% of patients and after 10 years 17.6% of patients had a visual acuity of ≤0.3 logMAR.CONCLUSION: Fractionated stereotactic radiotherapy is a good treatment option for small-, medium- and large-sized tumours with 5-year local tumour control of 92.2%. After 5 years, 22.0% of the patients had a good vision. Independently of tumour location, the visual acuity decreased significantly after treatment. Overall, the 5-year DFS was 77.0%.
