Primary CNS lymphoma management differs for immunocompetent patients. Methotrexate-based chemotherapy offers similar outcomes to radiation therapy with lower neurotoxicity risks.

Area of Science:

  • Neuro-oncology
  • Hematology
  • Immunology

Background:

  • Primary CNS lymphoma (PCNSL) is a rare non-Hodgkin's lymphoma affecting the brain.
  • Its incidence is rising in both immunocompromised and immunocompetent individuals.
  • PCNSL in immunocompetent patients presents unique diagnostic and therapeutic challenges.

Purpose of the Study:

  • To outline diagnostic and management strategies for primary CNS lymphoma in immunocompetent patients.
  • To compare the efficacy and toxicity of different treatment modalities.
  • To discuss the impact of treatment on neurotoxicity and quality of life.

Main Methods:

  • Review of characteristic imaging features for diagnosis.
  • Emphasis on stereotactic biopsy and avoiding corticosteroids.

  • Assessment of systemic disease, CNS, and ocular involvement.
  • Evaluation of treatment outcomes for surgery, radiation, and chemotherapy.

    • Main Results:

    • Surgical resection is not therapeutically beneficial, reserved for herniation.
    • Whole-brain radiation therapy (WBRT) alone has limited efficacy and high neurotoxicity risk in older adults.
    • Combined chemotherapy and WBRT improve response and survival versus WBRT alone.
    • Methotrexate-based chemotherapy without WBRT shows comparable outcomes with reduced neurotoxicity.

    Conclusions:

    • Early diagnosis via imaging and biopsy is crucial.
    • Methotrexate-based chemotherapy is a viable alternative to WBRT, potentially reducing neurotoxicity.
    • Management strategies must consider patient age and potential for cognitive impairment.
