Resumo
Objetivo: Comparara eficácia da citologia por imprint e da biópsia por congelamento na detecção de metástases em linfonodos satélites de mama durante o transoperatório. Métodos: Trata-se de uma revisão integrativa, com busca de estudos observacionais nas bases de dados MEDLINE, LILACS e SciElo, utilizando os descritores “Câncer de mama”, “Linfonodos Sentinelas” e “Métodos Diagnósticos Intraoperatórios”, bem como suas variantes em inglês e espanhol, abrangendo um período entre 2000 e 2024. Resultados: Após análise, 17 estudos foram elegíveis para a revisão, a maioria de caráter quantitativo. A biópsia por congelamento apresentou melhor sensibilidade (até 100%) na detecção de macro metástases, enquanto a citologia por imprint mostrou uma sensibilidade variada, de 52% a 90%. A especificidade foi elevada para ambos os métodos, com valores próximos de 100%. Contudo, ambos enfrentaram desafios na detecção de micro metástases, com frequentes relatos de falsos negativos. Considerações finais: A biópsia por congelamento é mais vantajosa em termos de sensibilidade, especialmente para macro metástases. No entanto, a citologia por imprint permanece uma opção viável, particularmente em cenários com recursos limitados. A combinação de ambas as técnicas pode aumentar a precisão diagnóstica e evitar cirurgias adicionais, o que sugere a necessidade de abordagens integradas para melhorar os resultados clínicos.
