Overview
Surgery is not the first-line treatment option for patients with intracerebral metastases. Surgical resection is usually reserved for patients with either a solitary brain metastasis or no extracranial spread of the primary tumor.[1]
Surgery
Stereotactic Radiosurgery
- Stereotactic radiosurgery is a type of external beam radiation therapy that allows radiation beams to be given to a specific area in the brain.
- This therapy aims many small beams of radiation from different directions at the tissue to be treated.
- It can direct the beams with precision to lessen the radiation to surrounding tissues, hence it causes less damage to healthy tissue than whole brain radiation therapy.
- A single large dose of radiation is given.
- Indications for stereotactic radiation therapy include:[2]
- One or a few metastatic brain tumors
- Stereotactic radiosurgery is usually used to treat people with upto 3 metastatic brain tumors, although this depends on the size and location of the tumors. Occasionally, selected cases with more than 3 tumors may be treated if the tumors aren’t too big. Stereotactic radiosurgery may not be suitable for people with large metastatic brain tumors.
- Alone or in combination with whole brain radiation therapy (WBRT)
- Progressive or recurrent brain metastases
- Stereotactic radiotherapy may be given after the person has had whole brain radiation therapy
Surgical Resection
Surgery is not the first-line treatment option for patients with intracerebral metastases. Surgical resection is usually reserved for patients with either:[1]
- Solitary brain metastasis
- No extracranial spread of the primary
The role of surgery in treatment of intracerebral metastases include:[1]
- Reduction of the size of the tumor as much as possible (debulking), if the metastasis is deep or is growing into the brain tissue and causing problems
- Reduction of the intracranial pressure
- Relief from the symptoms, if a brain metastasis cannot be completely resected
