What should you know about the PCV protocol for glioma?

A protocol is a structured treatment plan, not a promise that every person will receive the same doses or dates. PCV combines medicines that work through different effects on tumour cells. Glioma type, grade, molecular results, earlier treatment, blood counts, organ function, and neurological symptoms can all change the plan.

The schedule may include medicine days, planned breaks, blood tests, and reviews. It may be coordinated with [Radiotherapy](/treatments/radiation-oncology/radiotherapy/) or [Brain Tumour Surgery](/treatments/surgical-oncology/brain-tumour-surgery/), depending on your diagnosis and treatment stage.

Keep the protocol and medication list together. Confirm which capsules are taken at home, which medicine is given in clinic, what to do if you vomit, and when blood tests are due. Procarbazine has important interaction advice involving some medicines, foods, and alcohol; ask for the instructions that apply to you.

Tell the team about numbness, difficulty walking, constipation, nausea, mouth changes, reduced appetite, bruising, or unusual tiredness. These symptoms can affect dose timing or supportive medicines. Do not take a missed dose or add a supplement until the oncology team has advised you.

Use the urgent contact number for fever, chills, new infection symptoms, persistent vomiting, inability to keep fluids down, unexpected bleeding, or rapidly worsening weakness. Go to emergency care for a seizure that continues, sudden new speech or movement difficulty, severe breathing problems, or a major change in alertness.

Which version of the protocol applies to me, and what could change it? What are the medicine and rest days? Which results must be checked before the next treatment? How will scans and neurological assessments be used? Who should I contact overnight or during a holiday?
