Primary central nervous system lymphoma (PCNSL) is a rare brain cancer. Current treatments improve survival but cause neurotoxicity, especially in the elderly. Newer therapies aim to reduce side effects while maintaining efficacy.

Area of Science:

  • Oncology
  • Neurology
  • Hematology

Background:

  • Primary central nervous system lymphoma (PCNSL) is a rare non-Hodgkin lymphoma (NHL) confined to the brain and spinal cord.
  • It often presents with focal neurological deficits due to diffuse brain infiltration.
  • Corticosteroids aid symptom management but hinder diagnosis; radiotherapy and high-dose methotrexate improve outcomes.

Purpose of the Study:

  • To review the characteristics, treatment, and challenges of PCNSL.
  • To highlight the efficacy of methotrexate-based regimens and whole-brain radiotherapy.
  • To discuss the development of newer treatment strategies mitigating neurotoxicity.

Main Methods:

  • Literature review of PCNSL studies.
  • Analysis of treatment response rates and survival data.

Related Experiment Videos

  • Examination of neurotoxicity profiles in elderly patients.

    • Main Results:

    • High-dose methotrexate-based regimens combined with radiotherapy significantly improve PCNSL response rates and survival.
    • Whole-brain radiotherapy is a key component in PCNSL management.
    • Long-term survival is frequently complicated by severe neurotoxicity, particularly in older individuals.

    Conclusions:

    • PCNSL treatment has advanced, improving survival through combined modality approaches.
    • Neurotoxicity remains a significant challenge, especially for elderly patients.
    • Ongoing research focuses on developing less toxic regimens to preserve quality of life in PCNSL survivors.
