Clinicopathological profile of ependymomas with special reference to survival data – Experiences of a tertiary care center’

Ependymomas exhibit heterogeneity across age, location, histology, molecular nature and survival suggestive of an epigenetic component in its pathogenesis. The CNS WHO classification (2021) classifies ependymomas based on DNA methylation profiles. Studies suggest that molecular sub-types remain stable throughout the course of disease. Immunohistochemical expression of L1CAM, has been identified as a surrogate marker for ZFTA/c11orf95-RELA fusion in supratentorial ependymomas. This study aims at realising its utility specially in resource-poor setups.
