Glioblastoma in the elderly: Current and future trends

Data from a prospective trial large enough to provide a reliable analysis of outcome and prognostic factors in elderly patients with glioblastoma (GBM) are not yet available in the literature. Extensive tumor removal appears to offer patients the best possible chance of a speedy neurological recovery. Adequate radiotherapy (RT) should always be given to elderly patients if they have undergone gross total debulking and have maintained a good performance status. It is, however important to bear in mind that the risk of long-term cognitive impairment may be higher in patients on high-dose RT and that a short course of accelerated RT can achieve the same survival. Rather than being ruled out on principle, chemotherapy should be considered on the basis of an accurate assessment of the factors that might compromise the individual patient's tolerance to drugs administered. Temozolomide appears to be the best available chemotherapy in this population of patients. (c) 2006 Elsevier Ireland Ltd. All rights reserved.
