How effective is chemotherapy for glioblastoma?

Glioblastoma is a fast-growing brain tumour, so treatment usually combines surgery, radiotherapy and medicine when a person is fit enough. Chemotherapy may be given during and after radiotherapy, or later if the tumour grows again. Its benefit is assessed through brain scans, neurological symptoms, steroid needs and day-to-day function. Some medicines reach the brain better than others, and tumour features can influence how useful a particular drug is. Treatment aims to control the tumour and preserve function, not simply to change a scan.

Ask the neuro-oncology team how the medicine fits with surgery, radiotherapy, rehabilitation and seizure treatment. Bring a full list of medicines, including steroids and anti-seizure drugs, because interactions can matter. Report changes in speech, strength, balance, memory or alertness. Take anti-sickness medicines as prescribed and attend blood tests so the team can watch blood counts and organ function. Support with mobility, communication and home care can be arranged early.

Seek urgent medical advice for a new or worsening seizure, severe headache with vomiting, increasing weakness, confusion, fever, unusual bleeding or sudden vision or speech change. Call emergency services for a prolonged seizure, loss of consciousness, severe breathing difficulty or sudden one-sided weakness.

What is the goal of chemotherapy for me? Which scan or symptom changes will guide decisions? Do my tumour tests suggest a medicine is more suitable? How will treatment affect seizures, steroids, work and daily activities?
