I'm sorry you're facing a recurrence. This is a serious situation that requires personalized medical guidance from your oncology team.

What I can tell you about recurrent glioblastoma:

According to the Musella Foundation's Brain Tumor Guide, recurrent glioblastoma typically involves re-evaluation of your tumor's characteristics and consideration of several approaches:

  • Surgery may be considered if the tumor is resectable (can be safely removed)
  • GammaTiles (biodegradable wafers that release radiation) are FDA-approved for recurrent GBM and showed median survival of 18 months in published data—compared to the typical 5-7 months expected for recurrent disease
  • Genomic testing of the recurrent tumor to identify any new mutations that might respond to targeted therapies
  • Immunotherapy options like checkpoint inhibitors (Keytruda) or other immunotherapies
  • Chemotherapy (temozolomide) if your tumor is MGMT methylated
  • Clinical trials may offer access to newer treatments

What you need to do now:

  1. Meet with your oncology team to discuss your specific recurrence—location, size, and molecular characteristics matter enormously
  2. Ask about genomic testing of the recurrent tumor tissue
  3. Discuss all available options including surgery, radiation approaches, and clinical trials
  4. Consider a second opinion from a GBM specialist, ideally at an NCI-designated cancer center

The Musella Foundation (virtualtrials.org) and Cancer Commons both offer free resources to help patients navigate recurrent brain cancer options.
