Mecanismos de atuação dos derivados da vitamina E no combate ao câncer de mama: uma revisão integrativa
##plugins.themes.bootstrap3.article.main##
Resumo
Objetivo: realizar uma busca na literatura para compreender melhor o papel de tocoferóis e tocotrienóis no auxílio do combate ao câncer. Métodos: Trata-se de uma revisão integrativa utilizando os termos “vitamin E” AND “breast cancer” AND “estrogen” AND “oxidative stress” considerando artigos publicados nos últimos 10 anos; para a elaboração do artigo foi usado o método de fluxograma PRISMA. Resultados: Foram encontrados 11 estudos abordando aspectos in vitro, onde os pesquisadores utilizaram vários tipos e linhagens celulares; in vivo, cujo animais selecionados variaram de raça, idade e sexo; e clínicos, onde o objeto de estudo foi mulheres adultas de diferentes faixas etárias. Considerações finais: Existe um otimismo cauteloso quanto ao uso dos derivados de vitamina E. Os TTs demonstraram maior eficácia no controle dos mecanismos no tratamento do câncer de mama. Os estudos também relatam uma diminuição de complicações associadas, como o aumento da imunidade, impedindo a instalação de outras patologias.
