Elderly or frail patients with high-grade gliomas (HGG) can be effectively treated with an abbreviated course of radiation therapy (RT) consisting of 40 Gy in 15 fractions. Concurrent temozolomide (TMZ) improves survival in non-elderly patients with glioblastoma treated with standard schedule of 60 Gy in 30 fractions. We describe our institutional experience of combining abbreviated RT with concurrent TMZ for treatment of HGG. Between 1/1/2004 and 2/5/2010 31 patients were treated. Survival was estimated with the Kaplan–Meier method. Toxicity was scored according to CTCAE 3.0. Median age was 66 years (range 32–90), and 17 patients had Karnofsky performance score <70. At the time of analysis, 30 patients (98 %) had died, with a followup of 14 months in the surviving patient. Median survival was 11 months (range 1–20), and 41 % of patients were alive at 12 months. Thirty patients (97 %) had a decreased corticosteroid requirement after completion of therapy. Only one new hospitalization for worsening neurologic status was required during therapy. Grade 3–4 hematologic toxicity occurred in 11 patients. Abbreviated RT with concurrent TMZ provides a clinical benefit, is safe and tolerable in patients of advanced age or poor functional status.
