(T) Primary Tumor |
||||
|
TX |
Primary tumor cannot be assessed |
|||
|
T0 |
No evidence of primary tumor |
|||
|
T1 |
Tumor ≤ 2 cm in greatest dimension without extraparenchymal extension* |
|||
|
T2 |
Tumor > 2 cm but ≤ 4 cm in greatest dimension without extraparenchymal extension* |
|||
|
T3 |
Tumor > 4 cm &/or tumor having extraparenchymal extension* |
|||
|
T4a |
Moderately advanced disease: Tumor invades skin, mandible, ear canal, &/or facial nerve |
|||
|
T4b |
Very advanced disease: Tumor invades skull base &/or pterygoid plates &/or encases carotid artery |
|||
|
*Extraparenchymal extension is clinical or macroscopic evidence of invasion of soft tissues. Microscopic evidence alone does not constitute extraparenchymal extension for classification purposes. |
||||
|
(N) Regional Lymph Nodes |
||||
|
NX |
Regional lymph nodes cannot be assessed |
|||
|
N0 |
No regional lymph node metastasis |
|||
|
N1 |
Metastasis in a single ipsilateral lymph node, ≤ 3 cm in greatest dimension |
|||
|
N2 |
Metastasis in a single ipsilateral lymph node, > 3 cm but ≤ 6 cm in greatest dimension, or in multiple ipsilateral lymph nodes, none > 6 cm in greatest dimension, or in bilateral or contralateral lymph nodes, none > 6 cm in greatest dimension |
|||
|
N2a |
Metastasis in a single ipsilateral lymph node, > 3 cm but ≤ 6 cm in greatest dimension |
|||
|
N2b |
Metastasis in multiple ipsilateral lymph nodes, none > 6 cm in greatest dimension |
|||
|
N2c |
Metastasis in bilateral or contralateral lymph nodes, none > 6 cm in greatest dimension |
|||
|
N3 |
Metastasis in a lymph node, > 6 cm in greatest dimension |
|||
|
(M) Distant Metastasis |
||||
|
M0 |
No distant metastasis |
|||
|
M1 |
Distant metastasis |
|||
|
Χαρακτηριστικά Επέκτασης |
||||
|
Regional nodal spread from salivary gland carcinoma is relatively rare compared to other mucosal squamous cell carcinomas of head and neck Lymphatic spread varies according to histology and size of primary tumor
Regional nodal spread is orderly
|
Most nodal metastases will be apparent on initial physical examination, but bilateral spread is rare Distant metastasis is most commonly to
Adenoid cystic carcinoma
Mucoepidermoid carcinoma
