Glioblastoma metastasis

Glioblastoma most often affects the brain and can extend through nearby tissue. Spread may also involve the spinal coverings or fluid, causing symptoms away from the original site. New weakness, numbness, balance difficulty, vision or speech change, headaches, seizures or bladder symptoms need assessment; none of these symptoms alone confirms metastasis.

Doctors combine the history and neurological examination with MRI or other tests chosen for the suspected location. General information is available on the glioblastoma condition page.

Write down new symptoms, their timing and how they affect walking, speech, sleep and self-care. Ask whether imaging should include the spine, whether tissue or fluid testing is useful, and whether medicines can reduce swelling or seizures.

Depending on the location and previous treatment, the team may discuss radiotherapy, chemotherapy, brain tumour surgery or a clinical trial. The purpose may be to control tumour activity, relieve symptoms or preserve function.

Seek urgent medical advice for a new or worsening seizure, sudden weakness, new trouble speaking or seeing, severe headache with vomiting, rapidly increasing confusion, severe back pain or new loss of bladder control. If the person is difficult to wake, has breathing difficulty or sustains a serious injury, contact local emergency services.

Where is spread suspected, and which test can clarify it? What symptoms should trigger an immediate call? What are the goals and burdens of the available treatments?
