Background: Management of elderly patients with glioblastoma (GBM) is a controversial scenario and needs careful assessment and selection for aggressive radical treatment and chemotherapy protocols vs short-course radiotherapy without chemotherapy. Methods: We evaluated treatment patterns and outcome among elderly GBM patients treated in KFMC, Riyadh. The primary endpoint is overall survival (OS) and the secondary endpoint is progression-free survival (PFS); patients were reviewed regarding radiotherapy (Rth) fractionation modalities, surgery, and chemotherapy (CTR) given in correlation to PFS, OS. Results: Fifty-nine patients were recruited in our study with median age 66 (range: 60–81) years, and 47 (80%) were males. Thirtyseven patients (62.7%) had ECOG performance status (PS) ≥2, and 22 patients (37.3%) had PS <2. Gross total resection (GTR) and subtotal resection (STR) were done in 49 (82.9%) patients, and the median follow-up was 12 months. Thirty-eight (64%) patients received conventional Rth 60 Gray (Gy)/30 fractions or equal doses and 21 (36%) patients received hypofractionation Rth (40 Gy/15, 25 Gy/5 or 30 Gy/10 fractions). The median OS was 12 months (95%CI: 9.52–14.48). Receiving conventional Rth and completion of six months adjuvant CTR were significant factors for O.S (P=0.043 and 0.026), respectively. The median PFS was nine months (95% CI: 6.13–11.87). For univariate analysis, PS, time to start adjuvant treatment, and completion of six months CTR were significant factors for PFS. Conclusion: Conventional Rth and completion of adjuvant CTR lead to better OS, while earlier start of adjuvant treatment and the completion of adjuvant CTR were associated with a better PFS.
