Aim The goals of this study were to assess the activity and safety profile of bevacizumab in Taiwan Chinese patients with recurrent glioblastoma, to determine whether their response differed from that reported in other clinical trials, and to examine potential prognostic factors for survival. Methods We retrospectively assessed patients who received bevacizumab for recurrent glioblastoma between 2012 and 2015. Twelve predefined variables and the outcomes of our cohort were analyzed. Results In total, 76 patients with recurrent glioblastoma were analyzed. The overall response rate was 59.2%, including 19 patients (25.0%) with complete response and 26 patients (34.2%) with partial response. The median progression‐free survival and overall survival were 5.2 months (95% confidence interval [CI], 4.6–5.8 months) and 7.8 months (95% CI, 5.8–9.8 months), respectively. Multivariate analysis identified sex and grade 3 posttreatment hypertension (systolic ≥ 160 mmHg or diastolic ≥ 100 mmHg) as the only independent predictive factors for progression‐free survival and overall survival. Eastern Cooperative Oncology Group performance status was also found to be independently predictive of improved overall survival. Conclusion We showed good responses using bevacizumab and the progression‐free survival and overall survival were comparable with those previously reported. The adverse events of bevacizumab in our study were generally acceptable and manageable. Female sex, good performance status, and grade 3 posttreatment hypertension were suggested to be associated with survival benefits.
