What is the outlook for Primary CNS Lymphoma ?
Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis (chance of recovery) depends on the following:         - The patient's age and general health.     - The level of certain substances in the blood and cerebrospinal fluid (CSF).    - Where the tumor is in the central nervous system, eye, or both.    - Whether the patient has AIDS.         Treatment options depend on the following:          - The stage of the cancer.    - Where the tumor is in the central nervous system.    - The patient's age and general health.    - Whether the cancer has just been diagnosed or has recurred (come back).        Treatment of primary CNS lymphoma works best when the tumor has not spread outside the cerebrum (the largest part of the brain) and the patient is younger than 60 years, able to carry out most daily activities, and does not have AIDS or other diseases that weaken the immune system.
