What Primary CNS Lymphoma?

Primary central nervous system lymphoma (PCNSL) is a rare type of non-Hodgkin lymphoma that occurs in the brain, spinal cord, and/or eyes. It is the most common type of primary brain tumor in adults.

Risk Factors

The risk factors for PCNSL include:

* Immunodeficiency: People with weakened immune systems, such as those with HIV/AIDS or those who have undergone organ transplantation, are at an increased risk of PCNSL.

* Age: PCNSL is most common in adults over the age of 50.

* Gender: Men are more likely to develop PCNSL than women.

Symptoms

The symptoms of PCNSL can vary depending on the location of the tumor. Common symptoms include:

* Headaches

* Seizures

* Vision problems

* Speech problems

* Weakness or numbness in the arms or legs

* Confusion

* Memory loss

* Nausea and vomiting

Diagnosis

PCNSL is diagnosed with a combination of imaging tests, such as MRI or CT scans, and a biopsy of the tumor.

Treatment

The treatment of PCNSL typically involves a combination of surgery, radiation therapy, and chemotherapy. The goal of treatment is to remove the tumor and prevent it from coming back.

Prognosis

The prognosis of PCNSL depends on a number of factors, including the location of the tumor, the patient's age and overall health, and the stage of the disease. The 5-year survival rate for PCNSL is about 60%.
