Overview
The American Joint Committee on Cancer (AJCC) stages basal cell carcinoma based on the TNM system. T, M, and N are combined into stages, called stage grouping.
Basal Cell Carcinoma Staging
The American Joint Committee on Cancer (AJCC) stages basal cell carcinoma based on the TNM system:[1]
T - tumor
N - lymph nodes
M - metastasis
The following table summarizes the T categories:
T Categories | Description |
TX | Primary tumor cannot be identified |
Tis | Carcinoma in situ |
T1 | Tumor ≤2 cm in greatest dimension |
T2 | Tumor >2 cm, but ≤4 cm in greatest dimension |
T3 | Tumor >4 cm in maximum dimension or minor bone erosion or perineural invasion or deep invasion |
T4 | Tumor with gross cortical bone/marrow, skull base invasion and/or skull base foramen invasion |
T4a | Tumor with gross cortical bone/marrow invasion |
T4b | Tumor with skull base invasion and/or skull base foramen involvement |
The following table summarizes the N categories:
N categories | Description |
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 and ENE negative |
N2 | Metastasis in a single ipsilateral lymph node, ≤3 cm in greatest dimension and ENE positive; or >3 cm but ≤6 cm in greatest dimension and ENE negative; or metastases in multiple ipsilateral lymph nodes, none >6 cm in greatest dimension and ENE negative; or in bilateral or contralateral lymph node(s), none >6 cm in greatest dimension, ENE negative. |
N2a | Metastasis in single ipsilateral node ≤3 cm in greatest dimension and ENE positive; or a single ipsilateral node >3 cm but ≤6 cm in greatest dimension and ENE negative. |
N2b | Metastasis in multiple ipsilateral nodes, none >6 cm in greatest dimension and ENE negative. |
N2c | Metastasis in bilateral or contralateral lymph node(s), none >6 cm in greatest dimension and ENE negative. |
N3 | Metastasis in a lymph node >6 cm in greatest dimension and ENE negative; or in a single ipsilateral node >3 cm in greatest dimension and ENE positive; or multiple ipsilateral, contralateral, or bilateral nodes, any with ENE-positive status; or a single contralateral node of any size and ENE positive. |
N3a | Metastasis in a lymph node >6 cm in greatest dimension and ENE negative. |
N3b | Metastasis in a single ipsilateral node >3 cm in greatest dimension and ENE positive; or multiple ipsilateral, contralateral, or bilateral nodes, any with ENE-positive status; or a single contralateral node of any size and ENE positive. |
The following table summarizes the M categories:
M categories | Description |
M0 | No distant metastasis |
M1 | Distant metastasis |
The T, N, and M categories are combined into stages. The following table summarizes the stage grouping.
Stage | TNM Grouping |
0 | Tis, N0, M0 |
I | T1, N0, M0 |
II | T2, N0, M0 |
III | T3, N0, M0; T1-T3, N1, M0 |
IV | T1-T3, N2, M0; Any T, N3, M0; T4, any N, M0; Any T, any N, M1 |
