Quality-adjusted survival after tumor resection and/or radiation therapy for elderly patients with glioblastoma multiforme.
Prognostic factors are poorly defined for the elderly subpopulation with glioblastoma multiforme and have been exclusively related to conventional survival analysis. In this study an additional quality adjusted survival analysis (QAS) was performed. The prognostic evaluation of both survival- and QAS data after standard treatment were checked for concordant/discordant findings. Their usefulness for estimation of treatment effects and treatment strategies was then evaluated. ⋯ The dramatic decrease of QAS as compared with survival indicates extremely limited posttreatment improvement and/or rapid deterioration of the neurological score after standard treatment for the older subpopulation with glioblastoma multiforme. Supportive treatment should be considered for patients with a pretreatment KPS < 70.
