Overview
Basal Cell Carcinoma Staging
The American Joint Committee on Cancer (AJCC) stages basal cell carcinoma based on the TNM system: T - tumor N - lymph nodes M - metastasis
The following table summarizes the T categories:
| T Categories | Description |
| Tis | Carcinoma in situ |
| T1 | The tumor is blank 2 cm across AND has 0-1 high-risk features |
| T2 | The tumor is > 2 cm across AND has > 2 high-risk features |
| T3 | The tumor has grown into facial bones |
| T4 | The tumor has grown into other bones in the body or into the base of the skull |
The following table summarizes the N categories:
| N categories | Description |
| N0 | The tumor has not spread to the lymph nodes |
| N1 | The tumor has spread to 1 lymph node on the same side of the body as the main tumor AND is ≤ 3 cm across |
| N2a | The tumor has spread to 1 lymph node on the same side of the body as the main tumor AND is > 3 cm and ≤ 6 cm across |
| N2b | The tumor has spread to > 1 lymph node on the same side of the body as the main tumor AND is ≤ 6 cm across |
| N2c | The tumor has spread to > 1 lymph node on the other side of the body as the main tumor AND is ≤ 6 cm across |
| N3 | The tumor has spread to any nearby lymph node AND is > 6 cm across |
The following table summarizes the M categories:
| M categories | Description |
| M0 | The tumor has not spread to distant organs |
| M1 | The tumor has spread to distant organs |
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 |
