To provide neurosurgeons with a summary of the diagnostic work-up, treatment options, and prognostic factors for primary central nervous system lymphoma (PCNSL).
Key Findings:
PCNSL comprises less than 1% of lymphomas and 4% of brain tumors.
The median age at presentation is 65 years, with increased incidence in immunocompromised patients.
Untreated PCNSL has a dismal overall survival of 1.5 months.
5-year overall survival rates are 35% in the total population and only 6% in patients over 70 years old.
Interpretation:
PCNSL is a challenging condition with significant diagnostic and treatment delays, necessitating awareness among neurosurgeons for timely intervention.
Limitations:
Lack of international consensus on treatment protocols.
Prognostic models have not been externally validated.
Conclusion:
Early diagnosis and appropriate treatment are crucial for improving outcomes in patients with PCNSL, highlighting the need for neurosurgeons to be well-informed about this condition.
