Ferran Guedea<\/strong><\/a>, professor of the University of Barcelona<\/strong><\/a>, \u200b\u200bdirector of Radiation Oncology of the Catalan Institute of Oncology<\/strong><\/a> (ICO) and full academician of the Royal European Academy of Doctors-Barcelona 1914<\/strong> (RAED), has participated in the symposium “Nuevas tecnolog\u00edas de radioterapia: radiocirug\u00eda intracraneal”<\/strong> (New technologies of radiotherapy: intracranial radiosurgery), organized jointly by the ICO and the Autonomous University of Nuevo Leon<\/strong><\/a> (Mexico) and held in Monterrey on October 26 for the first 25 years of application of intracranial radiosurgery techniques at the Catalan Institute of Oncology.<\/p>\n The event has been developed within the framework of the collaboration agreements that RAED has signed with different Mexican institutions and has had more than half a thousand registered. Guedea and the ICO presented the works\u00a0“Calidad del proceso de radioterapia”<\/strong> (Quality of the radiotherapy process), “Initial results of high doses of RT and immunology response”<\/strong> and “The role of Brachytherapy in Prostate Cancer”<\/strong>.<\/p>\n Radiosurgery is a frequent therapy in the treatment of small malignant tumours at brain level and that can be used for the treatment of other non-tumour, vascular and functional neurological pathologies. In 1993, intracranial radiosurgery was started at the Catalan Institute of Oncology and since then more than 2,500 patients have been treated with this technique. During the symposium, the next implantation of functional intracranial radiosurgery to treat various benign pathologies in the field of neurosurgery was presented. This is the case of neuralgia of the trigeminal nerve and tremor of different origins, such as Parkinson’s or epilepsy, among others.<\/p>\n The symposium culminated with the signing of a new collaboration agreement between the University Centre Against Cancer<\/strong> of the Autonomous University of Nuevo Leon and the ICO. In this centre, the technologies in oncology have been incorporated under the direction of Rafael Pi\u00f1eiro<\/strong>, who was trained precisely in the Radiation Oncology Service of the Catalan Institute of Oncology.<\/p>\n <\/p>\n\n\t\t
