Description
Objetivo Avaliação da dose concomitante cumulativa no tratamento de RT com a técnica de IGRT e as possíveis estratégias a adotar de modo a minimizá-la. Materiais e Métodos Revisão sistemática por método PRISMA. Para a pesquisa de artigos científicos utilizaram-se as bases de dados PubMed e Science Direct. Foram definidos como critérios de inclusão artigos com estudo em fantomas pediátricos, artigos redigidos no idioma inglês e publicados entre janeiro de 2009 e junho de 2019. Resultados Principais Selecionaram-se sete artigos para elaborar o presente estudo, tendo em conta os critérios de elegibilidade. Vários estudos reportam que, devido à maior radiossensibilidade por parte dos doentes pediátricos, devem ser adotadas estratégias de
diminuição dos valores de mAs e kVp, quando se realiza o tratamento de RT com a técnica de IGRT,
para que não comprometa a correta visualização dos volumes de interesse. Conclusão A IGRT é fundamental na verificação da precisão do tratamento de Radioterapia nos doentes pediátricos. O recurso a imagens planares em vez de CBCT e protocolos de aquisição de imagem com valores de kVp otimizados, poderá diminuir a dose concomitante cumulativa para o doente, dado que esta não pode ser negligenciada devidos aos efeitos secundários que poderão originar.
Abstract: Objective To assess the cumulative concomitant dose in RT treatment with the IGRT technique and the possible strategies to adopt to minimize it. Materials and Methods Systematic review by PRISMA method. The PubMed and Science Direct databases were used to search for scientific articles. The inclusion criteria were defined as articles with studies in pediatric phantoms, articles written in English and published between January 2009 and June 2019. Main Results Seven articles were selected to prepare the present study, taking into account the eligibility criteria. Several studies report that, due to the greater radiosensitivity on the part of pediatric patients, strategies to decrease the values of mAs and kVp should be adopted when performing RT treatment with the IGRT technique, but not to compromise the correct visualization of the volumes of interest. ConclusionIGRT is fundamental in verifying the accuracy of radiotherapy treatment in pediatric patients. The use of planar images instead of CBCT and image acquisition protocols with optimized kVp values may reduce the cumulative concomitant dose to the patient since this cannot be neglected due to the side effects that may originate.
