18. Change in the risk stratification of prostate cancer after Slide Review by a uropathologist: the experience of a reference center for the treatment of prostate cancer
Introduction Brachytherapy is an option for treating low-risk prostate cancer (PC). Biochemical control of low-risk disease can reach 95%. The practice advocated is that a review of prostate biopsies should be mandatory before choosing the best treatment for patients with PC. Our objective was to evaluate the change in PC risk after review of a prostate bi

20. Comparação entre métodos de fixação de iodo radioativo em substrato de prata para confecção de fontes utilizadas em Braquiterapia / Comparison between methods for fixing radioactive iodine in silver substrate for manufacturing brachytherapy sources
Dentre as diversas formas de se tratar o câncer de próstata, a braquiterapia com sementes de iodo-125 é uma opção que apresenta ótimos resultados e menor ocorrência de efeito colateral. No presente trabalho diferentes métodos de deposição de iodo radioativo em substrato de prata foram comparados com o propósito de eleger a alternativa mais adequad

24. Evaluation of hela cell lineage response to β radiation from Holmium-166 embedded in ceramic seeds
This work studied the effects of β radiation of Ho-166 embedded in ceramic seeds on HeLa cells. Methodology consisted in the production of ceramic seeds with holmium-165 by sol-gel route. Chemical and physical characterizations of the seeds were performed. Subsequently, nuclear characterization was performed by gamma spectrometry. Experimental and theoretic
