Primary lymphoma of the brain is cancer of white blood cells that starts in the brain.
Brain lymphoma; Cerebral lymphoma; Primary lymphoma of the central nervous system; Lymphoma - brain
Causes, incidence, and risk factors
The cause of primary brain lymphoma is not known.
Patients who have a weakened immune system are at high risk of primary lymphoma of the brain. Common causes of a weakened immune system include HIV and organ transplants (especially heart transplants).
Primary lymphoma of the brain may be linked to Epstein-Barr Virus (EBV). This is the virus that causes mononucleosis, especially in people with HIV infection.
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.
Boosting the immune system, such as in those with HIV, may also be tried.
Without treatment, patients with primary brain lymphoma survive for less than 2 months. Patients who are treated with chemotherapy often survive 3 to 4 years or more, depending on whether the tumor stays in remission. Survival may improve with autologous stem cell transplant.
Possible complications include:
Chemotherapy side effects, including low blood counts
Radiation side effects, including confusion, headaches, nervous system (neurologic) problems, and tissue death
Return (recurrence) of the lymphoma
