When is radiotherapy recommended for glioma?

Glioma is a broad group of brain tumours, so treatment is not identical for every person. The team reviews the tissue diagnosis, grade, molecular features, MRI findings, tumour location, how much could be removed safely, and whether disease remains. A lower-grade tumour may be observed or treated with another approach in some situations, while a higher-grade or progressing tumour may prompt radiotherapy. Radiation is shaped around the target to limit exposure to nearby brain tissue. It can be combined with medicines or used after a period of monitoring. The plan should reflect both tumour biology and the person’s priorities.

Ask the neuro-oncology team to explain the pathology and molecular report in plain language, including what it means for timing. Bring MRI reports, medicine lists, and details of seizures, headaches, movement, speech, concentration, or vision. Ask whether a planning scan is needed, how the treatment position will be made comfortable, and what support is available for fatigue, nausea, or scalp irritation. If fertility, work, driving, or caregiving is a concern, raise it before the schedule is finalised. Keep written instructions for steroid and anti-seizure medicines.

Call the treating service promptly for a first seizure, a seizure that is different from usual, worsening headache with vomiting, increasing sleepiness, confusion, new weakness, difficulty speaking, or a sudden change in vision or balance. Emergency assessment is needed for prolonged seizure activity, collapse, or rapidly reduced responsiveness. These warning signs can have several causes, including swelling or treatment effects, and require clinical assessment rather than an assumption about the tumour.

Ask: What grade and molecular features guide my radiation decision? Is the aim to treat visible disease, the surgical area, or both? Could monitoring or another treatment be reasonable? How will radiotherapy fit with medicines? Which new neurological symptoms need urgent review?
