Overview
The staging of nasopharyngeal carcinoma is based on the TNM staging system.
Staging
The staging of nasopharyngeal carcinoma is based on the TNM staging system.
TNM staging
Primary tumor
- Tx: primary tumor cannot be assessed
- T0: no evidence of primary tumor
- Tis: carcinoma in situ
- T1: tumor is confined to the nasopharynx
- T2: tumor extends to soft tissues of the oropharynx and/or nasal fossa
- T2a: without extension to the parapharyngeal region
- T2b: with extension to the parapharyngeal region
- T3: invasion of adjacent bony structures and/or paranasal sinuses
- T4: invasion of any one or more of the following
- intracranial content
- cranial nerves
- infratemporal fossa/masticator space
- hypopharynx
- orbit
Nodal status
- Nx: nodes cannot be assessed
- N0: no evidence of nodal involvement
- N1: unilateral nodal involvement <6cm maximal diameter above supraclavicular fossa
- N2: bilateral nodal involvement <6cm maximal diameter above supraclavicular fossa
- N3
- N3a: >6 cm maximal diameter (unilateral or bilateral)
- N3b: involvement of the supraclavicular fossa
Metastases
- Mx: presence of metastases cannot be assessed
- M0: no evidence of metastases
- M1: distant metastases present
