Terminal Brain Cancer: Symptoms, Stages & What to Expect

Glioblastoma (GBM) and other high-grade gliomas are aggressive brain tumors. "Terminal" implies progression despite maximal treatment. Symptoms reflect tumor location, mass effect, and increased intracranial pressure (ICP).

Common Symptoms

• Headaches: Worse in morning, with Valsalva; often refractory to analgesics.
• Nausea/vomiting: From elevated ICP.
• Seizures: Focal or generalized; may be presenting symptom.
• Focal deficits: Weakness, aphasia, visual field cuts, sensory loss.
• Cognitive/behavioral: Confusion, memory loss, personality change, apathy.
• Late signs: Papilledema, Cushing's triad (hypertension, bradycardia, irregular breathing), obtundation, coma.

Progression & End-of-Life

• Median survival: GBM ~15 months with standard therapy (surgery, radiation, temozolomide).
• Recurrence is near-universal; second-line options limited.
• Terminal phase: increasing drowsiness, loss of communication, swallowing difficulty, seizures.

Supportive Care Priorities

• Dexamethasone for edema/ICP (taper to lowest effective dose).
• Antiepileptics for seizure control.
• Pain management, antiemetics, bowel regimen.
• Hospice/palliative care early integration improves quality of life.
• Advance directives, goals-of-care discussions.

Each patient's trajectory is unique. Multidisciplinary neuro-oncology and palliative teams optimize comfort and dignity.
