Meningiomas atípicos e anaplásicos em um hospital público de São Paulo, Brasil

Autoria SCIMAGO INSTITUTIONS RANKINGS

Meningiomas atipicos/anaplásticos (graus II e III da World Health Organization (WHO)) são menos comuns e tem prognóstico pior que os benignos. Este estudo visa analisar o prognóstico de pacientes com estes tumores.

Método

Sobrevida/sobrevida livre de doença (SLD) e índice de Karnofsky de 52 pacientes com meningiomas graus II (42) e III (9) tratados cirurgicamente foram avaliados (análises uni/multivariada).

Resultados

Pacientes <60 anos e com tumores grau II tiveram sobrevida mais longa. Tumores grau II , ressecção total e meningioma de novotiveram melhor SLD (análise univariada). Pacientes >60 anos, meningiomade novo e radioterapia tiveram sobrevida mais longa e, pacientes <60 anos e com tumores grau II tiveram SLD mais longa (análise multivariada). Recidiva ocorreu em 51% (39.2% Graus II e 66,7% Graus III). A mortalidade operatória foi 1,9%.

Conclusão

Idade <60 anos, meningiomas grau II e de novo foram preditores de melhor prognóstico entre pacientes com meningiomas graus II/ III.
