Brain metastases can occur months or even years after the original or primary cancer is treated. Brain metastases have a poor prognosis for cure, but modern treatments allow patients to live months and sometimes years after the diagnosis. [5]
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]
The average five-year survival rate for all (malignant) brain cancers in the United States is 33%. [4] Secondary, or metastatic, brain tumors are about four times as common as primary brain tumors, [2] [10] with about half of metastases coming from lung cancer. [2]
Brain metastasis can be single or multiple and involve any portion of the brain. Metastasis to dural structures generally occurs by hematogenous spread or direct invasion from a contiguous bone. Dural metastases can invade the underlying brain and cause focal edema and associated neurologic symptoms. These processes tend to cause seizures early ...
Metastatic brain cancer is over six times more common than primary brain cancer, as it occurs in about 10–30% of all people with cancer. [1] This is a list of notable people who have had a primary or metastatic brain tumor (either benign or malignant) at some time in their lives, as confirmed by public information. Tumor type and survival ...
Meningiomas, which develop in the meninges, are common primary brain tumors, representing approximately 37% of all brain tumors [15]. The incidence rate for meningiomas is 9.51 per 100,000 people [9]. Unlike gliomas, more than 98% of meningiomas are nonmalignant [15]. The 5-year survival rate for nonmalignant meningiomas is approximately 91% [9].
Nine years ago, Jimmy Carter held a news conference at the Carter Center in Atlanta to talk about his cancer diagnosis and treatment. Then age 91, Carter explained that a bad cold the previous May ...
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.
