Introduction
Steroids are commonly used for managing brain edema in patients with glioblastoma multiforme (GBM), treated with surgery and concomitant temozolomide-based chemoradiotherapy (CTRT). The adverse effects of glucocorticoids include lymphopenia, hyperglycemia, and risk of infection. We report the results of a meta-analysis evaluating the effects of steroids on outcome when associated with the treatment of GBM.
Methods
PubMed, the Cochrane Library, and Embase were searched from inception until September 2019 for observational or prospective studies reporting prognosis of adult patients with GBM and treated or not treated with steroids. Overall survival (OS) was the primary endpoint, and progression-free survival (PFS) was the secondary endpoint. The effect size was reported as hazard ratios (HRs) with a 95% confidence interval (CI), and an HR > 1 associated with the worst outcome in steroid users compared to non-users.
Results
Twenty-two publications were retrieved from studies selected for a total of 8,752 patients. In the primary analysis (n = 22 studies reporting data), OS was reduced in GBM patients taking steroids during treatment (HR = 1.54, 95% CI 1.37–1.75; p < 0.01). Similarly, PFS was inferior in steroid users in n = 9 studies with data available (HR = 1.28, 95% CI 1.1–1.49; p < 0.01).
Conclusions
In patients with GBM and treated with RT and/or CT, association with steroids significantly reduces survival and PFS. Use of the lowest dose of glucocorticoids for the shortest period needed to achieve the treatment goals and prevention of steroid-associated complications are essential aims of treatment of this disease.
