Performance of adjuvant treatment correlates with survival in reoperated glioblastomas

ABSTRACT

Objective To analyze cases of recurrent glioblastoma subjected to reoperation at a Brazilian public healthcare service.

Methods A total of 39 patients subjected to reoperation for recurrent glioblastoma at the Department of Neurosurgery, São Paulo Hospital, Federal University of São Paulo, from January 2000 to December 2013 were retrospectively analyzed.

Results The median overall survival was 20 months (95% confidence interval – CI = 14.9–25.2), and the median survival after reoperation was 9.1 months (95%CI: 2.8–15.4). The performance of adjuvant treatment after the first operation was the single factor associated with overall survival on multivariate analysis (relative risk – RR = 0.3; 95%CI = 0.2–0.7); p = 0.005).

Conclusion The length of survival of patients subjected to reoperation for glioblastoma at a Brazilian public healthcare service was similar to the length reported in the literature. Reoperation should be considered as a therapeutic option for selected patients.

RESUMO

Objetivo Analisar o papel da reoperação em pacientes com glioblastoma recidivado em um serviço público no Brasil.

Métodos Foram analisados retrospectivamente 39 pacientes submetidos à reoperação por recorrência de glioblastoma no Departamento de Neurocirurgia da Universidade Federal de São Paulo, no período de janeiro de 2000 até dezembro de 2013.

Resultados A sobrevida global mediana foi de 20 meses (IC 95% = 14.9–25.2), e a sobrevida mediana após a reoperação foi de 9.1 meses (IC 95% = 2.8–15.4). A realização de tratamento adjuvante após a primeira cirurgia foi o único fator associado com a sobrevida global numa análise multivariada (RR = 0.3; IC 95% = 0.2–0.7; p = 0.005).

Conclusão A sobrevida dos pacientes submetidos à reoperação em um serviço público no Brasil é semelhante à reportada pela literatura. A reoperação deve ser considerada como uma opção terapêutica em pacientes selecionados.
