Central nervous system tumours are the 10th most frequent cause of mortality due to cancer. Immunohistochemistry has become an important tool in the diagnosis of brain tumours. Brain tissue and meninges tumours comprise a heterogeneous group with diverse biological behaviour, treatment management, and different prognoses. Although conventional haematoxylin-eosin staining is crucial for diagnosis, diagnostic neuropathology has benefited from the inclusion of immunohistochemistry and recent advances in the field over the past 20 years.

The study showed that the median Ki67 value was significantly higher in high-grade neuroglial tumours and metastatic tumours.</p><p><strong>Conclusions: </strong>Intracranial tumours cause significant morbidity and mortality in patients. Diagnostic, prognostic and predictive biomarkers evaluated in patient biopsy specimens and/or body fluids are important in neuropathological oncology.
