ABSTRACT

Atypical/anaplastic (World Health Organization (WHO) grades II and III) are less common and have poorer outcomes than benign meningiomas. This study aimed to analyze the outcome of patients with these tumors.Method Overall/recurrence-free survivals (RFS) and the Karnofsky Performance Scale of 52 patients with grades II (42) and III (9) meningiomas surgically treated were analyzed (uni/multivariate analysis).Results Total/subtotal resections were 60.8%/35.3%. Patients <60 years-old and grade II tumors had longer survival. Grade II tumors, total resection andde novo meningioma had better RFS (univariate analysis). Patients >60 years-old, de novo meningioma and radiotherapy had longer survival and patients <60 years-old and with grade II tumors had longer RFS (multivariate analysis). Recurrence rate was 51% (39.2% Grade II and 66.7% Grade III). Operative mortality was 1.9%.Conclusion Age <60 years-old, grade II tumors and de novomeningiomas were the main predictors for better prognosis among patients with grades II and III meningiomas.


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.

ABSTRACT

Objective: To analyze the clinical outcome of patients with foramen magnum (FM) meningiomas. Method: Thirteen patients (11 Feminine / 2 Masculine with FM meningiomas operated on through lateral suboccipital approach were studied. Clinical outcome were analyzed using survival (SC) and recurrence-free survival curves (RFSC). Results: All tumors were World Health Organization grade I. Total, subtotal and partial resections were acchieved in 69.2%, 23.1% and 7.7%, respectively, and SC was better for males and RFSC for females. Tumor location, extent of resection and involvement of vertebral artery/lower cranial nerves did not influence SC and RFSC. Recurrence rate was 7.7%. Operative mortality was 0. Main complications were transient (38.5%) and permanent (7.7%) lower cranial nerve deficits, cerebrospinal fluid fistula (30.8%), and transient and permanent respiratory difficulties in 7.7% each. Conclusions: FM meningiomas can be adequately treated in public hospitals in developing countries if a multidisciplinary team is available for managing postoperative lower cranial nerve deficits. .


Objetivo: Analisar as evoluções clínicas de 13 pacientes com meningiomas do forame magno (FM). Método: Foram estudados 13 pacientes com meningiomas do FM (11 Feminino / 2 Masculino) operados por abordagem suboccipital lateral. As evoluções clínicas foram analisadas usando curvas de sobrevida (SC) e de sobrevida livre de doença (RFSC). Resultados: Os 13 tumores eram Grau I da Organização Mundial de Saúde. Ressecções total, subtotal and parcial foram obtidas em 69,2%, 23,1 e 7,7%, respectivamente. A SC foi melhor para homens e a RFSC foi melhor para mulheres. Localização/ extensão da ressecção/envolvimento da artéria vertebral/nervos cranianos baixos não influenciaram a SC/RFSC. A taxa de recorrência foi 7,7%. A mortalidade operatória foi zero. As principais complicações foram déficits de nervos cranianos baixos transitórios (38,5%) e permanentes (7,7%); fístula de líquido cefalorraquidiano (30,8%) e dificuldades respiratórias transitórias e permanentes em 7,7% cada. Conclusões: Meningiomas do FM podem ser adequadamente tratados em hospitais públicos em países em desenvolvimento se houver uma equipe multidisciplinar para cuidar de déficits de nervos cranianos baixos pós-operatórios. .
