Right temporal Glioblastoma now with subtotal resection what does that mean

Understanding Your Subtotal Resection for Glioblastoma

I'm glad you're seeking to understand your diagnosis and treatment. Let me break down what this means for you.

What is a Glioblastoma?

A glioblastoma is a grade 4 glioma—the most aggressive type of brain tumor. According to the NCCN Guidelines for Patients: Brain Gliomas, glioblastomas are "aggressive, life-threatening gliomas" that can grow rapidly. The fact that yours is in the right temporal lobe (the side part of your brain) is important information your care team is using to plan your treatment.

What Does "Subtotal Resection" Mean?

Subtotal resection means your neurosurgeon removed most—but not all—of your tumor during surgery. Here's what the NCCN Guidelines explain about this:

• Full resection (also called "gross total resection") removes all the tumor that can be seen on imaging
• Partial or subtotal resection removes part of the tumor

Your surgeon likely couldn't safely remove 100% of the tumor because:

• The remaining tumor may be in a critical area of your brain
• Removing more tissue could damage important brain functions
• The tumor may be in a difficult location to reach safely

Why This Matters

According to the NCCN Guidelines, "For most gliomas, there are microscopic tumor cells that can't be seen, even with imaging systems like MRI, in the tissue outside of the tumor. So some tumor cells are almost always left behind after the tumor is removed."

This is why additional treatment is typically needed after surgery.

What Comes Next?

The NCCN Guidelines indicate that after surgery recovery, you'll likely receive:

• Radiation therapy to target remaining tumor cells
• Possibly chemotherapy (your care team will discuss this)
• Regular MRI scans to monitor your tumor

Important Next Steps

1. Ask your neurosurgeon exactly how much tumor was removed and why complete removal wasn't possible
2. Meet with your multidisciplinary team (neurosurgeon, radiation oncologist, neuro-oncologist) to discuss your complete treatment plan
3. Get clear information about your specific tumor characteristics, as these guide treatment decisions

This is a serious diagnosis, but many people with glioblastoma are now living longer than statistics suggest. Your care team will work with you to create a personalized treatment plan.
