glioma
Let an agent explain gliomas and their classification in general terms, relay diagnosis and treatment information from oncology guidelines and patient organisations, and route personal symptoms, scans and treatment questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain gliomas and their classification in general terms, relay diagnosis and treatment information from oncology guidelines and patient organisations, and route personal symptoms, scans and treatment questions to clinicians.
A tumour arising from glial cells of the brain or spinal cord, including astrocytomas, oligodendrogliomas and ependymomas, graded from slow-growing to highly malignant such as glioblastoma, and classified by histology and molecular markers; gliomas are the most common primary brain tumours and are treated by surgery, radiotherapy and chemotherapy according to type and grade.
What it is for: Not applicable; a disease.
It can be explain types, grades and classification; relay treatment approaches from guidelines; relay support resources; route personal questions to clinicians.
Distinguishing features
Arises from glial cells
Graded 1 to 4 with molecular classification
Infiltrative growth in the brain
Treatment by surgery, radiotherapy and chemotherapy
What it looks like
Not visible externally; seen on brain imaging as a mass, and under the microscope as glial tumour cells.
Physical character
share of primary brain tumours: about a third proportion - and most malignant primary brain tumours
WHO grades: 1-4 grades - by type
How it is recognised
Tumour of glial cells in the central nervous system
Classified by cell type, grade and molecular markers such as IDH mutation
Meningiomas and metastases are other brain tumours

- How should guideline versions be linked?
- The registry entry has merged aliases for rare and paediatric tumour types; should they be split off?
