Abstract: |
BACKGROUND- Primary central nervous system lymphoma (PCNSL) is an uncommon primary brain tumor that is being diagnosed with increased frequency in both the immunocompetent population and the population infected with human immunodeficiency virus (HIV). REVlEW SUMMARY- PCNSL is an important diagnostic consideration in any patient with an enhancing lesion on neuroimaging, particularly in older adults and patients infected with HIV. Because this tumor has a propensity for widespread dissemination throughout the central nervous system, initial evaluation should include cerebrospinal fluid cytology and a slit lamp ophthalmologic examination. The addition of methotrexate-based chemotherapy to whole brain radiotherapy has improved disease control and long-term survival for patients diagnosed with PCNSL but may have significant associated neurologic toxicity for patients older than 60 years of age. CONCLUSIONS- The present challenge is to additionally improve the outcome of PCNSL patients, both in regards to disease control and treatment-related toxicity. To this end, several ongoing and planned studies are examining new therapeutic strategies for the treatment of PCNSL. |
