Article
Background Glioma patients often experience cognitive problems, which are associated with decreased functional independence and health-related quality of life. However, the prevalence and nature of cognitive impairment in these patients is relatively underreported, particularly during stable disease. In this study we determine the prevalence of cog...
Article
Background Protocols for assessment of (neuro)psychological outcomes in lower-grade glioma patients vary between hospitals. This potentially complicates generalization of these outcomes. We compared standardized scores on tests of two frequently impaired cognitive domains (attention and executive functioning (EF)), and two relevant patient-reported...

Background Even though fatigue is one of the most prevalent and burdensome symptoms in patients with glioma, its etiology and determinants are still poorly understood. We aimed to identify which demographic, tumor- and treatment-related characteristics and patient-reported outcome measures (PROMs) are associated with or are predictors of fatigue in...

Background: Cannabinoids have been suggested to alleviate frequently experienced symptoms of reduced mental well-being such as anxiety and depression. Mental well-being is an important subdomain of health-related quality of life (HRQoL). Reducing symptoms and maintaining HRQoL are particularly important in malignant primary brain tumor patients, as...
Preprint
Background: Glioma patients experience a multitude of symptoms, impacting health-related quality of life. We aimed to assess frequency and burden of patient-reported symptoms in glioma patients with stable disease and whether patients would consider treatment. We also explored how symptoms co-occur and interact within a network.Methods: Patients ra...
Article
BACKGROUND Glioma patients experience a high symptom burden contributing to poorer quality of life. Symptoms include depression, cognitive impairment, and fatigue and vary throughout the disease. These symptoms are rarely studied from a comprehensive perspective, while their interdependence may be relevant for their development, perpetuation, and u...
Article
BACKGROUND Patients with diffuse glioma experience many tumor- and treatment-related symptoms, including fatigue, cognitive deficits, and anxiety. It remains unclear how the frequency and burden of these symptoms change over time and specifically which symptoms patients experience during the stable phase of the disease. We assessed the frequency an...
Article
BACKGROUND Gliomas are primary brain tumors with a dismal prognosis. Reducing symptoms and maintaining quality of life (QoL) are main treatment aims in glioma patients. Mental well-being is an important subdomain of QoL. Cannabinoids have been suggested to alleviate frequently experienced symptoms of reduced mental well-being such as anxiety or dep...

IntroductionProgression-free survival (PFS) in glioma patients varies widely, even when stratifying for known predictors (i.e. age, molecular tumor subtype, presence of epilepsy, tumor grade and Karnofsky performance status). Neuronal activity has been shown to accelerate tumor growth in an animal model, suggesting that brain activity may be valuab...

... Therefore, as expected, cEEG data was available in only a minority of this cohort. Post-operative brain oscillatory activity measured by magnetoencephalography (MEG) has been associated with glioma survival outcomes [16,17], although conflicting reports exist [18], which may be attributable to different glioma populations or methodologies studied. In contrast to using a quantitative oscillatory power metric of functional connectivity, hyperexcitability in this study reflected standardized EEG patterns on the ictal-interictal continuum and presumably corresponded to neuronal hyperactivity at the extreme of the spectrum [19]. ...
