About primary central nervous system lymphoma
The most common site for primary central nervous system (CNS) lymphoma is the brain. There may be more than one tumour present, although 60- 70% of cases have a single tumour. Primary CNS lymphoma may also start in the layers that form the outer covering of the brain (meninges) or in the eyes (ocular lymphoma).
Who does primary CNS lymphoma commonly affect?
It is most common in people aged in their 50s and 60s, but can occur at any age.
Causes of primary central nervous system lymphoma
Whilst the exact causes of primary CNS lymphoma are unknown, a weakened immune system such as in people who have HIV/AIDS, or have had an organ transplant are at increased risk of developing this form of lymphoma, however the incidence in people with a normal immune system is rising significantly.
Treatment of primary central nervous system lymphoma
Treatment for primary CNS lymphoma includes chemotherapy and often radiation therapy. Steroid therapy is often given before chemotherapy, as this helps reduce the swelling around the tumour, and may even shrink the tumour, reducing the raised intracranial pressure. Chemotherapy is given into a vein, and often also into the fluid surrounding the brain (intrathecally). The chemotherapy drug is most commonly given this way, and is also given in high doses intravenously – either on its own or in combination with other chemotherapy drugs and/or steroids. Radiotherapy uses high-energy rays to destroy the cancerous cells and can be an effective treatment for primary CNS lymphoma in younger people. It is used in combination with chemotherapy and steroid treatment. Surgery is only used to provide diagnostic tissue, and is never curative alone. Anticonvulsants may be given if seizures occur as a result of a tumour.
If treatment is insufficient or if the disease recurs, some people are given a stem cell transplant using either their own stem cells (autologous) or those from a donor (allogeneic). New treatments are being researched all the time and people may be invited by their doctor to take part in a clinical trial to compare a new treatment or strategy with the best available standard treatment.
