Abstract BACKGROUND AND PURPOSE: Optimal treatment for elderly patients with glioblastoma multiforme is not well defined. We evaluated the efficacy of post-operative radiotherapy with or without concomitant and/or adjuvant temozolomide in patient, aged > or = 60 years to assess survival and identify prognostic factors of survival. METHODS: A retrospective analysis of overall survival and progression-free survival in patients with newly diagnosed glioblastoma multiforme aged > or = 60 years treated with post-operative radiotherapy with or without temozolomide chemotherapy was conducted at our institutions. Prognostic factors were determined by univariate and multivariate analyses. RESULTS: Of 75 study participants (54.7\% male; median age at first diagnosis, 65.1 years), 29 (38.7\%) underwent gross total resection, whereas others underwent partial resection or biopsy only. All but 1 patient received radiotherapy. Twenty patients received concomitant temozolomic e only. Adjuvant temozolomide (1-50 cycles) was administered in 42 patients; 16 received > or = 6 cycles. Median overall survival was 10.3 months. One- and 2-year overall survival rates were 42.6\% and 6.7\%, respectively. Median progression-free survival was 4.1 months. Radiochemotherapy was generally well tolerated. Median overall survival was 15.3 and 29.6 months for patients who received 6-12 cycles and >12 cycles of adjuvant temozolomide, respectively. There were no significant differences in overall survival between age groups (60-64, 65-69, and > or = 70 years). Adjuvant temozolomide, Karnofsky performance status > or = 70, and additional surgery after progression were significant prognostic factors of longer overall survival (p<0.05). CONCLUSIONS: Radiochemotherapy, including > or = 6 cycles of adjuvant temozolomide, was safe and prolonged survival of glioblastoma patients aged > or = 60 years. Aggressive therapy should not be withheld from patients aged > or = 60 years with good performance status because of age.
