What should you know about RCC brain metastases?

Renal cell carcinoma can spread beyond the kidney. When tumour cells form a deposit in brain tissue, symptoms may include headache, seizures, weakness on one side, changes in speech, balance problems, vision changes, or altered thinking. Some people have no symptoms and the finding is made on imaging.

The care team considers the number, size, and position of brain deposits, swelling around them, symptoms, disease elsewhere in the body, and general health. A brain scan with contrast may help define the problem and guide treatment. The plan is individual and may involve oncology, neurosurgery, radiation specialists, and supportive-care clinicians.

Attend the recommended scan and specialist appointments, and tell the team about headaches, seizures, falls, weakness, or changes in behaviour. Bring a list of medicines, including steroids or anti-seizure treatment, because some medicines need careful adjustment.

Treatment may include focused radiation such as stereotactic radiosurgery, surgery for a suitable accessible deposit, whole-brain radiotherapy in selected situations, medicines for renal cell carcinoma, or a combination. The team will explain the purpose and likely effects of each option.

Call emergency services for a first seizure, a seizure that does not stop, sudden weakness, new difficulty speaking, severe confusion, loss of consciousness, or a sudden severe headache. Do not drive yourself after a seizure or when neurological symptoms are active.

Where are the brain deposits and is there swelling? What treatment is being recommended and what is its goal? Should I take a steroid or anti-seizure medicine? How might treatment affect thinking, movement, or daily activities? Which symptoms should trigger an emergency call?
