In our institution, 103 glioblastoma multiforme (GBM) patients aged from 55 to 83 years were treated since November 1994 as follows. All patients underwent surgical intervention (gross total resection, n = 35; subtotal resection, n = 38; stereotactic biopsy, n = 30). Subsequently all patients were offered radiotherapy and chemotherapy with CCNU. Results were as follows: 101 patients started radiotherapy, 93 patients completed it (96% of the patients aged < 65 years and 85% of the patients > or =65 years). All patients received at least 1 cycle of chemotherapy (median 3 cycles). Chemotherapy-associated toxicity was generally mild, more pronounced in females and did not increase with age. Median time to progression was 10.5+/-3.2 months for the patients < 65 years and 5.1+/-1 months for patients > or =65 years. median overall survival was 17.5+/-3.8 months in patients < 65 years and 8.6+/-1 months in patients > or =65 years (p < 0.0001). In multivariate analysis, age and female sex remained independent prognostic factors. Our data indicate that a treatment concept including concomitant radio- and chemotherapy is feasible even in elderly patients with GBM.
