Abstract

Introduction: Depression and neurocognitive function, particularly executive functioning (EF), have been associated with overall survival (OS) in patients with glioblastoma (GBM). However, the combined effect of depressive symptoms and impaired EF upon OS has not been reported. Methods: Patients with GBM (N = 102) completed neuropsychological assessment postoperatively, including the Beck Depression Inventory-Second Edition (BDI-II) and the Trail Making Test Part B (TMTB). Median splits were used to determine cut-points denoting elevated depressive symptoms on the BDI-II and impaired EF on TMTB. Patients were stratified into four groups: low depressive symptoms/low EF impairment (− Dep/− Imp; N = 23), high depressive symptoms/low EF impairment (+ Dep/− Imp; N = 28), low depressive symptoms/high EF impairment (− Dep/+Imp; N = 28), and high depressive symptoms/high EF impairment (+ Dep/+Imp; N = 23). The Kaplan–Meier method, log-rank test, and Cox regression were used to examine differences in survival between groups. Results: Relative to − Dep/− Imp patients (median OS = 22.8 months), median OS in all other patient groups was shorter (+ Dep/− Imp OS = 16.6; − Dep/+Imp OS = 14.8; +Dep/+Imp OS = 10.8; all p <.05). With the exception of KPS and age, groups did not differ in distribution of clinical and demographic characteristics. Neither KPS nor age modified the independent effect of BDI-II and TMTB on OS in Cox regression models. Conclusions: The presence of depressive symptoms and impaired EF are independently associated with shorter OS in patients with GBM. These results suggest that routine neuropsychological assessment of mood and cognition may help refine prognosis and facilitate initiation of psychological and cognitive interventions, which can improve patient quality of life, and warrants further investigation.
