Treatment for brain metastases is primarily palliative, with the goals of therapy being reduction of symptoms and prolongation of life. However, brain metastases harboring a mutation in the BRAF kinase at position V600 are effectively druggable with small molecule inhibitors such as dabrafenib.
Whole brain radiotherapy (WBRT) is a treatment option for patients with brain metastases. In WBRT, radiation therapy is administered broadly, to the whole brain, over multiple treatments. In WBRT, radiation therapy is administered broadly, to the whole brain, over multiple treatments.
Clinically, CNS metastasis is known to cause haemorrhage or obstruction in the cranial portion of the CNS leading to hydrocephalus. [9] Additionally, metastatic lesions are usually discrete within the brain and appear as spherical masses that displace the brain parenchyma rather than invading the tissues. [10]
A theory was developed that the brain was likely a pharmacologic sanctuary where sub-clinical metastases were protected from cytotoxic drugs by the blood–brain barrier. Oncologists hypothesized that treatment of this sub-clinical disease with radiation therapy may stamp out the malignant process before it could advance to cause symptoms.
This is a concern during treatment of brain tumors and brain metastases, especially where there is pre-existing raised intracranial pressure or where the tumor is causing near-total obstruction of a lumen (e.g., trachea or main bronchus). Surgical intervention may be considered prior to treatment with radiation.
For brain metastases, these treatment options include whole brain radiation therapy (WBRT), surgery, and systemic therapies. However, a recent systematic review found no difference in the affects on overall survival or deaths due to brain metastases when comparing SRS treatment alone to SRS plus WBRT treatment or WBRT alone.
