Medical care of patients with brain tumors

Patients with brain tumors require close attention to medical issues resulting from their disease or its therapy. Effective medical management results in decreased morbidity and mortality and improved quality of life. The most frequent neurology-related issues that arise in these patients include seizures, peritumoral edema, venous thromboembolism, fatigue, and cognitive dysfunction. This article focuses on the most recent findings for the management of the most relevant medical complications among patients with brain tumors.

Increasing evidence suggests that anticoagulation in patients with thromboembolic complications is safe even when they are receiving antiangiogenic therapy. There are also increasing data to support the use of newer, non-enzyme-inducing antiepileptic drugs, which have the advantage of lacking interactions with antineoplastic agents and are as effective as their older counterparts at preventing seizures. Relatively few studies have addressed the management of fatigue and depression, and definitive recommendations cannot be made.

Corticosteroids to treat vasogenic edema should be used at the minimum amount required to control symptoms and should be tapered as quickly as possible. Anticonvulsants should be used only if patients have had seizures. Non-enzyme-inducing antiepileptic drugs are preferred to minimize interactions with concurrently administered chemotherapy. Thromboembolic complications are common and are preferably treated with low-molecular-weight heparins. Only patients with hemorrhagic complications require an inferior vena cava filter. Cognitive deficits are frequent in patients with brain tumors and include problems such as poor short-term memory, distractibility, personality change, emotional lability, loss of executive function, and decreased psychomotor speed. Stimulants can help to improve these symptoms.
