It is often challenging to diagnose PCNSL due to its clinical and radiological overlap with various central nervous system (CNS) inflammatory conditions and other brain tumors. Cytokines and chemokines in cerebrospinal fluid (CSF) have shown potential as biomarkers for PCNSL, but the conclusion on their diagnostic utility is unavailable. This study intended to assess the role of CSF cytokines and chemokines in differentiating PCNSL from other CNS disorders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We searched electronic databases extensively to find studies that examined the sensitivity and specificity of CSF cytokine or chemokine levels in PCNSL\u2014synthesizing results involved standardizing the units of measurement where necessary and verifying data accuracy.

The increased levels of CSF interleukin (IL)-10 and C-X-C motif Chemokine Ligant 13 (CXCL 13) were significantly associated with a positive diagnosis of PCNSL. Diagnostic accuracy measures demonstrated the promising discriminatory power of CSF IL-10 and IL-10:IL-6 ratio.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our findings revealed considerable diversity in the diagnostic accuracy of individual biomarkers.
