When to Seek Emergency Care for Glioblastoma

I appreciate this important question. While I can provide educational information about warning signs, emergency decisions should always involve your patient's oncology team and primary care doctor, who know their specific situation best.

Common Glioblastoma-Related Emergencies

Glioblastoma is an aggressive brain tumor that can cause serious symptoms requiring immediate medical attention. Here are situations that typically warrant emergency care:

Neurological Emergencies (Seek ER immediately)

  • Severe headache - especially if sudden, different from usual, or accompanied by other symptoms
  • Seizures - new onset or uncontrolled seizures despite medication
  • Loss of consciousness or difficulty staying awake
  • Sudden weakness or paralysis on one side of the body
  • Vision changes - sudden loss of vision or double vision
  • Speech difficulties - sudden inability to speak or understand speech
  • Loss of balance/coordination - severe dizziness or inability to walk
  • Confusion or personality changes - acute mental status changes

Other Urgent Situations

  • Severe nausea/vomiting - especially if unable to keep down medications or fluids
  • High fever (over 101°F) - could indicate infection
  • Difficulty breathing or chest pain
  • Signs of stroke - facial drooping, arm weakness, speech difficulty (FAST test)

Important Context

According to NCCN Guidelines for Central Nervous System Cancers, glioblastoma patients are at risk for increased intracranial pressure (pressure inside the skull), which can cause rapid deterioration. Brain swelling, bleeding, or tumor progression can develop quickly.

Questions to Ask Your Care Team NOW

Rather than waiting for an emergency, I'd recommend asking your oncologist:

  1. "What specific symptoms should prompt us to go to the ER versus calling you first?"
  2. "Should we have a 24/7 contact number for urgent questions?"
  3. "Are there any medications we should have on hand for emergencies?" (like seizure rescue medications)
  4. "What hospital should we go to if we need emergency care?" (ideally one familiar with brain tumors)
  5. "How quickly should symptoms develop before we seek emergency care?"

When in Doubt

If you're unsure whether something is an emergency, it's better to err on the side of caution. You can:

  • Call your oncology team's emergency line first
  • Call 911 if you can't reach them
  • Go to the nearest ER if symptoms are severe

Brain tumors can change rapidly, and your medical team would rather evaluate a concern that turns out to be minor than have a serious situation go untreated.
