Rare Neuronal, Glial and Glioneuronal Tumours in Adults.
Level 5 - mechanism / opinion, no new human data
Narrative review summarizing diagnostic classifications without systematic search or original data
PubMed 36831464 · doi:10.3390/cancers15041120
What was done
The authors reviewed the diagnostic criteria, classification frameworks, and management challenges of rare adult central nervous system tumours with glial, neuronal, or glioneuronal features following the 2021 World Health Organization (WHO) classification update.
What was found
The abstract reports no quantitative data, odds ratios, or patient counts. It states that the 2021 WHO classification integrates multimodal diagnostic criteria—combining histological, immunohistochemical, genetic, and methylomic parameters—to refine definitions of known tumor entities and identify novel tumor types.
Why it matters
It outlines how advanced molecular diagnostics and methylomics are now necessary alongside traditional histology to accurately classify rare adult brain tumors.
Limits
The abstract provides no empirical data, sample sizes, search methodology, or quantitative evaluation of diagnostic accuracy or treatment outcomes.
