Glioblastoma multiforme (GBM) is the most common and fatal brain tumor in adults. Prognosis remains dismal and median overall survival rarely exceeds 12 months. In this study, we evaluated the demographic and clinical features of Turkish glioblastoma patients from single institute to identify the important prognostic factors which might be related with patient outcomes in this population, retrospectively. Demographic data, clinicopathological data and treatment parameters (i.e. extent of surgical resection, radiotherapy and use of chemotherapy) were obtained from medical records. SPSS version 22 was used for all statistical analyses. The median progression-free survival and overall survival was 9,9 and 13,7 months; respectively. The group of patients with the highest mean overall survival had a tumor at the fronto-temporal region, followed by frontal localization. In univariate analysis, age, concurrent chemoradiotherapy and adjuvant temozolomide use were all predictors for both PFS and OS. However, in multivariate analysis, age and concurrent radiotherapy were significant predictors of survival. Patients receiving cyberknife after recurrence had longer OS. We retrospectively evaluated glioblastoma patients from single institute, the results supported previously reported factors that influence survival time in glioblastoma.
