Compreendendo a origem dos paragangliomas
Conteúdo do artigo principal
Resumo
Introdução: Os paragangliomas são tumores neuroendócrinos raros e de crescimento lento, frequentemente agrupados com os feocromocitomas devido às suas semelhanças celulares. Eles surgem a partir de células da crista neural e podem ser encontrados dentro dos sistemas nervosos simpático ou parassimpático, com apresentações clínicas variadas, dependendo da sua localização e funcionalidade.
Objetivo: Elaborar ampla revisão sobre paragangliomas no contexto da neurocirurgia.
Método: A revisão utilizou as bases PubMed, Scopus e Web of Science. Foram incluídos estudos sobre epidemiologia, fisiopatologia, características genéticas e manifestações clínicas. Os critérios de inclusão abrangeram estudos clínicos, revisões sistemáticas e estudos de caso publicados entre 2000 e 2023. A análise foi focada nos aspectos neurocirúrgicos do tratamento, riscos associados e os avanços no diagnóstico e manejo dessas neoplasias.
Resultado: Foram incluídos 68 artigos que focaram o tema referido nesta revisão.
Conclusão: Apesar de serem predominantemente benignos, aproximadamente 10% apresentam comportamento maligno. Sua natureza altamente vascularizada e a proximidade com estruturas neurovasculares críticas apresentam desafios cirúrgicos. O teste genético, especialmente para mutações no gene SDH, desempenha papel importante para o direcionamento do manejo e na avaliação do risco de malignidade.
