Search for: [Abstract = "correlation between the degree of tumour height regression and the applied treatment revealed that the tumours treated with Ru\-106 isotope showed lower regression range \(47.5% lower after 3 years\) and were stable at greater initial height \(52.5%\) than the tumours treated with I\-125 isotope. In the latter group the height reduction was more considerable \(67.3%\) and \; stabilization occurred at lower initial height \(32.7%\).Positive local results, which were defined as tumour growth inhibition with or without tumour size reduction, were observed in 130 patients \(76.0%\) treated with Ru\-106 brachytherapy and in 195 patients \(95.1%\) treated with I\-125 brachytherapy. Cox regression analysis revealed that the tumour regression type \(model II and III\), the apical height radiation dose \( 100 Gy\) and the patient’s age \( 40\) were the factors which significantly determined a positive result of the treatment.Local treatment failure, understood as a relapse or tumour growth in spite of the treatment, occurred in 40 patients \(23.4%\) treated with Ru\-106 isotope and in 9 patients \(4.4%\) treated with I\-125 isotope. Cox regression analysis showed that the radiation dose below 100 Gy applied to the top of the tumour and the epithelioid histopathological type of melanoma were the factors which significantly increased the risk of tumour relapse. The study of factors affecting the primary lack of res"]
