Overview
According to the TNM staging system, there are [number] stages of medulloblastoma based on the tumor size and the extent of metastasis. Each stage is assigned [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].[1][2][3]
TNM Classification of Medulloblastoma
T: Primary Tumor
| T | Description |
| TX | Primary tumor cannot be assessed |
| T0 | There is no evidence of primary tumor |
| T1 | Tumor size <3 cm in diameter |
| T2 | Tumor size ≥3 cm in diameter with no evidence of extension |
| T3a | Tumor size >3 cm in diameter with extension into aqueduct of Sylvius or foramen of Luschka |
| T3b | Tumor size >3 cm in diameter with definite spread into the brain stem |
| T4 | Tumor size >3 cm in diameter with extension past aqueduct of Sylvius or down past foramen magnum |
N:Regional Lymph Nodes
- An N classification cannot be applied to medulloblastoma.
M: Distant Metastasis
Classification of Medulloblastoma by Staging
