Title in Portuguese
Protocolos de implementação e avaliação dos tratamentos de braquiterapia oftálmica com rutênio-106 em um hospital geral
Keywords in Portuguese
Braquiterapia Oftálmica
Melanoma Uveal
Radioterapia
Rutênio-106
Abstract in Portuguese
A Braquiterapia oftálmica utiliza radionuclídeos, como o Rutênio-106 no tratamento de melanomas uveais e outras neoplasias oculares. Para realização desse procedimento é necessária uma interação da equipe multidisciplinar principalmente entre a Oftalmologia, Oncologia, Radioterapia, Física Médica e Enfermagem, envolvendo estrutura física e profissionais qualificados para garantir os processos e resultados do procedimento. Este estudo tem o objetivo de avaliar os primeiros tratamentos de braquiterapia oftálmica com Rutênio-106 e também estabelecer protocolos e processos para implementação da técnica em um Hospital Geral. Os resultados obtidos para os primeiros 11 casos tratados entre 2015 e 2017, sendo 10 melanomas e 1 hemangioma, evidenciaram baixa toxicidade aguda. Foram analisados 5 pacientes com seguimento de 5 a 13 meses. Houve regressão da lesão em todos os pacientes, com média de 28% no ápice e 12% na base no período de até 12 meses, sendo observado uma regressão progressiva durante o período de avaliação. Os protocolos foram utilizados e validados durante todas as etapas do tratamento. O uso do Ru-106 mostra-se alternativa viável no tratamento de lesões oculares, sendo primordial a capacitação e integração da equipe e seguimento de protocolos para o êxito do tratamento.

Implementation protocols and treatments evaluation of 106-rutenium ophthalmic brachytherapy in a general hospital

Abstract in English
Ophthalmic Brachytherapy uses radionuclides, such as Ruthenium-106 in the treatment of uveal melanomas and other ocular tumors. For this procedure is necessary a multidisciplinary interaction between Ophthalmology, Oncology, Radiotherapy, Medical Physics and Nursing, involving physical structure and qualified professionals to guarantee the processes and results of the procedure. This study aims to evaluate the first ophthalmic brachytherapy treatments with ruthenium- 106 and also to establish protocols and processes for the implementation of this service in a General Hospital. The results obtained for the first 11 cases treated between 2015 and 2017, being 10 melanomas and 1 hemangioma, showed low acute toxicity. Five patients were followed up for 5 to 13 months. There was regression of the lesion in all of these patients, with a mean of 28% at the apex and 12% at the base in the period close to 1 year, with a progressive regression during the evaluation period. The protocols were used and validated during all stages of treatment. The use of 106-Ru is a viable alternative in the treatment of ocular tumors, being the team qualification and the correct follow-up of the protocols crucial for the treatment success.
