A Scoping Review of Exercise Oncology in the Primary Brain Tumor Patient–Caregiver Dyad

Background: Primary malignant brain tumors (PBT) impose substantial burdens on patients and caregivers. Caregivers are essential in the delivery of outpatient care for patients with PBT but experience high levels of fatigue, distress, and health decline. Although exercise is known to improve outcomes in cancer patients, interventions tailored specifically to the PBT patient–caregiver dyad remain limited. Dyadic intervention, as well as exercise oncology, are emerging areas of active research in neuro-oncology. This scoping review incorporates both principles to evaluate the existing literature on exercise interventions on primary brain tumor patient–caregiver dyads. Methods: We conducted a comprehensive search of MEDLINE (PubMed), Embase, CINAHL (EBSCO), Rehabilitation & Sports Medicine (EBSCO), and Cochrane Central (Ovid) in December 2025 for studies involving exercise interventions that included adult PBT patients and caregivers. Results: Of the 1126 records screened, eight studies were included: four yoga-based interventions (three feasibility trials and one ongoing multicenter RCT), one pilot ski-based intervention, and three aerobic and resistance training-based interventi
