Resumo: Cervix cancer is a tumor of high incidence in Brazil specially in the areas of low social and economic status. Since one of the most important treatment modalities for this disease is radiation therapy, a survey of the present situation in the country was devised by using the 117 oncology radiation centers as the basis for collecting the information. A special form was send to collect information on the number of patients per stage, the treatment technique used, type of sources and the interest to participate in a national protocol. Eighty percent of the centers returned the form and the results showed that 89% of the tumors were located in the cervix and 11% in the endometrium; 60% are still using manual after loading technique; 70% received combined tele + brachy, 7% are centers still using Ra-226. In addition, it was found that only 49% of the expected new cases a year of cervix cancer had been treated by radiation therapy, when the expected number would have been around 80%. This is reasonable, if one considers that the majority of the patients have advanced disease, as radiation therapy is the ideal treatment for these cases. Finally the response regarding the participation in a national clinicai trial was positively answered by the great majority of the centers.

Os objetivos deste estudo são levantar o número e a forma como os tumores de colo uterino vêm sendo tratados no Brasil e, através desta análise, estudar a possibilidade de um protocolo nacional de tratamento. Foi elaborado um formulário com dados cadastrais e detalhes sobre o número, a maneira e o equipamento usado no tratamento dos tumores ginecológicos, que foi enviado a 117 instituições para serem respondidos, espontaneamente. Foram obtidos 80% de retorno, e a análise mostrou que 89% eram tumores do colo e 1 1 % do corpo do útero. Setenta e cinco por cento das instituições são privadas e apenas 5% são em hospitais-escola. Cinqüenta e oito por cento dos serviços ainda utilizam cálculo manual na braquiterapia e 70% das pacientes receberam tratamento combina do de tele-braquiterapia. Dos 22.750 casos de tumor do colo do útero estimados pelo Instituto Nacional de Câncer (INCA), para o ano de 1995, apenas 49% receberam radioterapia a despeito de se esperar uma taxa de 80%. Os autores fazem um ensaio sobre as possíveis causas que levam a discrepância entre estes dados e sugerem um protocolo nacional multi-institucional, coordenado pelo INCA e pelo Colégio Brasileiro de Radioloia (CBR), para o tratamento dos tumores de colo do útero, levando em consideração a realidade nacional.INCA2022-09-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigos, Avaliado pelos paresapplication/pdfhttps://rbc.inca.gov.br/index.php/revista/article/view/280210.32635/2176-9745.RBC.1998v44n2.2802Revista Brasileira de Cancerologia; Vol. 44 No. 2 (1998): Apr./May/June; 101-107Revista Brasileira de Cancerologia; Vol. 44 Núm. 2 (1998): abr./mayo/jun.; 101-107Revista Brasileira de Cancerologia; v. 44 n. 2 (1998): abr./maio/jun.; 101-1072176-9745reponame:Revista Brasileira de Cancerologia (Online)instname:Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)instacron:INCAporhttps://rbc.inca.gov.br/index.php/revista/article/view/2802/1681https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCanary , Paulo Cesar Almeida, Carlos Eduardo de 2023-01-18T15:09:55Zoai:rbc.inca.gov.br:article/2802Revistahttps://rbc.inca.gov.br/index.php/revistaPUBhttps://rbc.inca.gov.br/index.php/revista/oairbc@inca.gov.br0034-71162176-9745opendoar:2023-01-18T15:09:55Revista Brasileira de Cancerologia (Online) - Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)false
