Corticosteroid use in patients with glioblastoma at first or second relapse treated with bevacizumab in the BRAIN study.

Journal Article (Journal Article;Multicenter Study)

BACKGROUND: Vascular endothelial growth factor inhibitors have corticosteroid-sparing effects in patients with high-grade gliomas. We assessed corticosteroid use in patients with recurrent glioblastoma treated with bevacizumab (BEV) in the BRAIN study (J Clin Oncol 2009;27:4733-4740). METHODS: BRAIN was a phase II, multicenter, randomized, noncomparative trial of BEV alone (n = 85) or in combination with irinotecan (CPT-11) (n = 82) in adults with recurrent glioblastoma. Median corticosteroid dose for patients who used corticosteroids at baseline was summarized by treatment arm; the percentage of patients who had sustained (≥50% corticosteroid dose reduction for ≥50% of time on study drug) or complete (discontinuation of corticosteroid for ≥25% of time on study drug) reduction in corticosteroid dose overall and by objective response and progression-free survival was calculated. The incidence of corticosteroid-related adverse events was summarized. RESULTS: In each treatment group, 50% of patients were using systemic corticosteroids at baseline. The majority of those experienced a reduction in dose while receiving BEV-based therapy. Thirteen (30.2%) BEV and 20 (46.5%) BEV + CPT-11 patients had a sustained reduction of corticosteroid dose; 7 (16.3%) BEV and 9 (20.9%) BEV + CPT-11 patients had a complete reduction of corticosteroid dose. The majority of patients who had an objective response or progression-free survival >6 months experienced corticosteroid dose reduction. Approximately 64% of patients who used corticosteroids while receiving BEV-based therapy experienced infection. CONCLUSION: BEV may have corticosteroid-sparing effects in patients with recurrent glioblastoma. Corticosteroid reduction may positively affect patient health-related quality of life. Given the exploratory nature of the analyses in a noncomparative study, these results should be interpreted cautiously.
