The cause of primary brain lymphoma is not known.

People with a weakened immune system are at high risk for primary lymphoma of the brain. Common causes of a weakened immune system include HIV/AIDS and having had an organ transplant (especially heart transplant).

Primary lymphoma of the brain may be linked to Epstein-Barr Virus (EBV), especially in people with HIV/AIDS. EBV is the virus that causes mononucleosis.

Primary brain lymphoma is more common in people ages 45 to 70. The rate of primary brain lymphoma is rising. But this cancer is still very rare.

Treatment

Primary lymphoma of the brain is usually first treated with corticosteroids. These medicines are used to control swelling and improve symptoms. The main treatment is with chemotherapy.

Younger people may receive high-dose chemotherapy, possibly followed by an autologous stem cell transplant.

Radiation therapy of the whole brain may be done after chemotherapy.

Boosting the immune system, such as in those with HIV, may also be tried.

You and your health care provider may need to manage other concerns during your treatment, including:

Outlook (Prognosis)

Without treatment, people with primary brain lymphoma survive for less than 2 months. Those treated with chemotherapy often survive 3 to 4 years or more. This depends on whether the tumor stays in remission. Survival may improve with autologous stem cell transplant.
