The occurrence of radiation-induced results was analyzed by estimating the risk by applying the Kaplan-Meier method, i.e., the 'time to event' analysis. The Cox model test was used for the univariate and multivariate risk factor analyses. The median follow-up was 51 months after primary treatment.Tumor recurrence was found in 21 patients $(3.5\%)$ and repeated treatment due to insufficient effect after the initial ruthenium-106 brachytherapy was performed in 40 patients $(6.6\%).$ The 5-year cumulative risk of recurrence was $4.0\%$ and that of insufficient effect was $7.3\%.$ Thirteen patients $(2.1\%)$ underwent a secondary enucleation; 8 because of a local recurrence and 5 because of severe post-brachytherapy complications. The cumulative enucleation risk was $2.3\%$ after 5 years and $2.9\%$ after 10 years, corresponding to eye preservation of 97.7 and $97.1\%,$ respectively. In forty-two patients $(7.2\%),$ metastatic disease was diagnosed during the follow-up. The metastatic rate as calculated by the Kaplan-Meier method was 9.0, and $13.1\%$ at 5 and 10 years, respectively.Our study demonstrated that ruthenium-106 brachytherapy is an excellent treatment option for achieving local tumor control and eye preservation in well-selected patients. The metastatic rate is in agreement with that of previous studies analyzing small to medium size uveal melanomas.}, keywords = {Humans / Uveal Neoplasms: radiotherapy / Brachytherapy: methods / Brachytherapy: adverse effects / Melanoma: radiotherapy / Ruthenium Radioisotopes: therapeutic use / Male / Female / Middle Aged / Aged / Retrospective Studies / Adult / Radiation Injuries: etiology / Aged, 80 and over / Treatment Outcome / Risk Factors / Neoplasm Recurrence, Local: prevention $\&$ control / Neoplasm Recurrence, Local: radiotherapy / Young Adult / Eye Enucleation / Prevalence / Adolescent / Ruthenium Radioisotopes (NLM Chemicals) / Ruthenium-106 (NLM Chemicals)}, cin = {ED01}, cid = {I:(DE-He78)ED01-20160331}, pnm = {899 - ohne Topic (POF4-899)}, pid = {G:(DE-HGF)POF4-899}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:38354842}, doi = {10.1055/a-2268-0985}, url = {https://inrepo02.dkfz.de/record/298918}, }
