Overview
Medical Therapy
The treatment options for intracerebral metastases include the following:[1]
Treatment for brain metatases | |||||||||||||||||||||||||||||||||||||||||||||||||
Symptomatic treatment | Definitive treatment | ||||||||||||||||||||||||||||||||||||||||||||||||
Corticosteroids | Anticonvulsants | Whole brain radiotherapy | Surgery | Stereotactic radiosurgery | Chemotherapy | ||||||||||||||||||||||||||||||||||||||||||||
Symptomatic Treatment
- Corticosteroid therapy is essential for all patients with brain metastases, as it prevents the development of cerebral edema, as well as treating other neurological symptoms such as headaches, cognitive dysfunction, and emesis. Dexamethasone is the corticosteroid of choice.[2][3]
- Anticonvulsants should be used in patients with brain metastases who experience seizures, as there is a risk of status epilepticus and death. Phenytoin is the most commonly used drug, but valproic acid and other anticonvulsants can also be used. Newer anticonvulsants have the advantage of fewer toxic side effects.[3][4]
- Hyperosmolar agents (i.e., mannitol) can be given to reduce intracranial pressure.[4]
- Recently, methylphenidate and donepezil have been used to improve cognition, mood, and quality of life.
Therapeutic Treatment
Radiation Therapy
- The most widely used treatment for patients with multiple brain metastases is whole brain external beam radiotherapy (WBRT).[2]
- The role of radiation therapy in treatment of intracerebral metastases include:[5]
- Whole brain radiation therapy (WBRT) is a type of external beam radiation therapy. Indications for WBRT include:[5]
- Multiple brain metastases
- More than 3 metastatic brain tumors or in people with poor performance status
- Single brain metastasis that cannot be removed by surgery
- Brain tumors are in an inaccesible area or if the affected area would be damaged by surgery
- Post surgical removal of a single brain metastasis
- To destroy remnant cancer cells post surgery and reduce the chance of recurrence
