Glioblastoma Treatment Pathway

See where clinical trials fit into your treatment journey

Initial Diagnosis: Maximal Safe Resection

Surgery to remove as much tumour as safely possible, often guided by brain mapping

Standard: Awake craniotomy with intraoperative MRI and fluorescence guidance (5-ALA) where available

Stupp Protocol: Radiotherapy + Temozolomide

The gold standard first-line treatment since 2005 — concurrent and adjuvant chemotherapy with radiotherapy

Standard: 60 Gy radiotherapy over 6 weeks with daily temozolomide, then 6-12 cycles adjuvant temozolomide

Maintenance: Tumour-Treating Fields (TTF)

Wearable device delivering alternating electric fields to disrupt cancer cell division

Standard: Optune device worn ≥18 hours/day alongside temozolomide — approved but not yet widely available on NHS

Recurrent Disease: Novel Immunotherapy & Targeted Approaches

At recurrence, trials explore dendritic cell vaccines, CAR-T, oncolytic viruses, and targeted agents

Emerging: Dendritic cell vaccines (ICT-107), oncolytic viruses (G207), CAR-T targeting EGFRvIII, and IDH-targeted therapy for secondary GBM

About Glioblastoma

What is Glioblastoma?

Glioblastoma (GBM) is the most common and aggressive primary brain tumour in adults, with about 3,200 new cases per year in the UK. Symptoms include headaches, seizures, cognitive changes, and weakness. It grows rapidly and diffusely infiltrates brain tissue, making complete surgical removal impossible.

Why Trials Matter

Median survival for GBM is only 15-18 months with standard treatment. Fewer than 10% of patients survive 5 years. Trials are critical — every major advance in GBM treatment came from clinical research. The blood-brain barrier makes drug delivery challenging, making novel approaches (viral therapy, immunotherapy, convection-enhanced delivery) especially important.

MGMT & Biomarkers

MGMT promoter methylation status is the most important biomarker in GBM. Patients with methylated MGMT respond better to temozolomide (median survival 24+ months vs 14 months). IDH mutation, if present, indicates secondary GBM with a somewhat better prognosis. Ask your neuro-oncologist about molecular testing.
