- Primary Tumour (T)
- TX, Primary tumour cannot be assessed
- T0, No evidence of primary tumour
- T1, Tumour 5 cm or less in greatest dimension*
- -T1a, Superficial tumour
- -T1b, Deep tumour
- T2, Tumour larger than 5 cm in greatest dimension*
- -T2a, Superficial tumour
- -T2b, Deep tumour
- *Note: Superficial tumour is located exclusively above the superficial fascia without invasion of the fascia; deep tumour is located either exclusively beneath the superficial fascia, superficial to the fascia with invasion of or through the fascia, or both superficial to and beneath the fascia
- Regional Lymph Nodes (N)
- NX, Regional lymph nodes cannot be assessed
- N0, No regional lymph node metastasis
- N1**, Regional lymph node metastasis
- **Note: Presence of positive nodes (N1) in M0 tumours is considered Stage III
- Distant Metastasis (M)
- M0, No distant metastasis
- M1, Distant metastasis
