Background: Gliomas are associated with significant healthcare burden, yet reports of costs are scarce. While many costs are unavoidable there may be treatable symptoms contributing to higher costs. We describe healthcare and societal costs in glioma patients at high risk for depression and their family caregivers, and explore relationships between costs and treatable symptoms. Methods: Data from a multicenter randomized trial on effects of internet-based therapy for depressive symptoms were used (NTR3223).
