Description |
| 1 |
Localized only (localized, NOS)
- Confined to brain, NOS
- Confined to ventricles
+ Tumor invades or encroaches upon ventricular system
- Infratentorial tumor confined to
+ Brain stem or meninges of brain stem (one side)
* Medulla oblongata
* Midbrain (mesencephalon)
* Pons
+ Cerebellum or meninges of cerebellum (one side or midline)
* Lateral lobes
* Median lobe of cerebellum
* Vermis
+ Hypothalamus
+ Thalamus
- Infratentorial tumor
+ Both cerebellum and brain stem involved with tumor on one side
- Supratentorial tumor confined to
+ Cerebral hemisphere (cerebrum) or meninges of cerebral hemisphere (one side):
* Frontal lobe
* Occipital lobe
* Parietal lobe
* Temporal lobe |
| 2 |
Regional, NOS
- Bone (skull)
- Contralateral hemisphere
- Corpus callosum (including splenium)
- Major blood vessel(s)
- Meninges (e.g., dura)
- Nerves (cranial, NOS)
- Spinal cord/canal
- Supratentorial tumor extends infratentorially to involve
+ Brain stem
+ Cerebellum
+ Hypothalamus
+ Pallium
+ Posterior cranial fossa
+ Thalamus
- Infratentorial tumor extends supratentorially to involve
+ Anterior cranial fossa
+ Cerebrum (cerebral hemisphere) (excluding hypothalamus, pallium, thalamus)
+ Corpus callosum
+ Middle cranial fossa
+ Suprasellar brain
+ Tapetum
- Tumor crosses the midline |
| 7 |
Distant site(s)/lymph node(s) involved
- Distant site(s) (including further contiguous extension)
+ Circulating cells in cerebral spinal fluid (CSF)
+ Nasal cavity
+ Nasopharynx
+ Other direct extension outside CNS
+ Posterior pharynx
- Distant lymph node(s), NOS
- Distant metastasis, NOS
+ Carcinomatosis
+ Distant metastasis WITH or WITHOUT distant lymph node(s)
+ Metastasis within CNS and CSF pathways
*"Drop" metastasis
* Extra-neural metastasis
* Metastasis outside the CNS |
