Survival score scales of patients operated with spinal metastases: retrospective application in a Brazilian population
Escalas de prognóstico em pacientes operados com metástases vertebrais: aplicação retrospectiva em população brasileira
ABSTRACT
Spinal cord epidural metastasis (SEM) is a common complication of systemic cancer. Predicting these patient’s survival is a key factor to select the proper treatment modality, but the three most used score scales to predict their survival (Tokuhashi revised score, Tomita score and Bauer modified score) were designed in single institutions and their reliability to predict correctly the patient’s survival were first tested only in those specific populations. This prognostication issue is addressed in this article, evaluating retrospectively the survival of 17 patients with SEM from a Brazilian general hospital with these score scales. Our results show that the actual survival of those patients were worse than the predicted of all three score scales, suggesting that differences between the different populations might have affected their reliability and alert that their usage as a major factor to select the most appropriate treatment have to be done with caution.
RESUMO
Metástases vertebrais são uma complicação comum em pacientes com câncer sistêmico. Avaliar o prognóstico e a sobrevida desses pacientes é um fator de grande importância para escolher o tratamento mais adequado, porém as três escalas mais usadas atualmente para prever a sobrevida deles (Tokuhashi revisada, Tomita e Bauer modificada) foram desenhadas em instituições isoladas, e sua habilidade em estimar corretamente a sobrevida desses pacientes foram testadas primeiramente apenas nessas populações específicas. Essa questão de estimar o prognóstico é abordada nesse artigo, analisando retrospectivamente a sobrevida de 17 pacientes com metástase vertebral provenientes de um hospital geral no Brasil com essas escalas. Nossos resultados apontam que a sobrevida real desses pacientes foi menor que a prevista pelas três escalas, sugerindo que as diferenças entres as diferentes populações podem ter afetado a aplicabilidade delas. Assim, alertamos que o uso dessas escalas em populações diferentes das estudadas originalmente deve ser feito com cuidado.
