- Abstract
Background and Purpose: Glioblastoma, WHO grade IV is the most frequent primary malignant brain tumor in adults. There are few articles and result about the efficacy of bevacizumab monotherapy. The aim of our paper is to examine the effect of bevacizumab therapy on progression free and overall survival in an extended database of recurrent glioblastoma patients., Methods: In our retrospective study, patients with recurrent glioblastoma treated with bevacizumab had been collected. All of our patients received first line chemo-irradiation according the Stupp protocol treatment. The histological diagnosis was primary or secondary glioblastoma in every patient. The prognostic features of primary and secondary glioblastomas were statistically analyzed., Results: Eighty-six patients were selected into the retrospective analysis. The histological diagnosis was primary glioblastoma in 65 patients (75.6%) and secondary glioblastoma in 21 patients (24.4%). The mean follow up period was 36.5 months. The mean second progression free survival beside bevacizumab therapy was 6.59 months and the mean overall survival was 24.55 months. In secunder glioblastoma cases, the mean second progression free survival was 6.16 months and the mean overall survival was 91.94 months., Conclusion: The bevacizumab therapy is a safe option in recurrent glioblastoma patients. Bevacizumab therapy has a positive effect both on progression free and overall survival and our results confirm the findings in the literature. There is no statistically significant difference in the second progression free survival between glioblastoma subtypes.
