Background To assess management patterns and outcome in patients with glioblastoma multiforme (GBM) treated during 2008–2010 in Spain.
Methods Retrospective analysis of clinical, therapeutic, and survival data collected through filled questionnaires from patients with histologically confirmed GBM diagnosed in 19 Spanish hospitals.
Results We identified 834 patients (23% aged >70 years). Surgical resection was achieved in 66% of patients, although the extent of surgery was confirmed by postoperative MRI in only 41%. There were major postoperative complications in 14% of patients, and age was the only independent predictor (Odds ratio [OR], 1.03; 95% confidence interval [CI],1.01–1.05; P = .006). After surgery, 57% received radiotherapy (RT) with concomitant and adjuvant temozolomide, 21% received other regimens, and 22% were not further treated. In patients treated with surgical resection, RT, and chemotherapy (n = 396), initiation of RT ≤42 days was associated with longer progression-free survival (hazard ratio [HR], 0.8; 95% CI, 0.64–0.99; P = .042) but not with overall survival (HR, 0.79; 95% CI, 0.62–1.00; P = .055). Only 32% of patients older than 70 years received RT with concomitant and adjuvant temozolomide. The median survival in this group was 10.8 months (95% CI, 6.8–14.9 months), compared with 17.0 months (95% CI, 15.5–18.4 months; P = .034) among younger patients with GBM treated with the same regimen.
Conclusions In a community setting, 57% of all patients with GBM and only 32% of older patients received RT with concomitant and adjuvant temozolomide. In patients with surgical resection who were eligible for chemoradiation, initiation of RT ≤42 days was associated with better progression-free survival.
