Overview
The staging of Merkel cell cancer is based on the TNM staging system.
Staging
- According to the TNM staging system, merkel cell cancer is classified into 4 stages based on the following:
- Tumor size
- Involvement of lymph nodes, and
- Metastasis
- The stages of Merkel cell carcinoma are shown in the table below:[1]
| Stage | Primary Tumor (T) | Lymph Node (N) | Metastasis (M) |
| 0 | In situ |
|
|
| IA | ≤2 cm |
|
|
| IB | ≤2 cm |
|
|
| IIA | >2 cm |
|
|
| IIB | >2 cm |
|
|
| IIC | Invades bone, muscle and cartilage |
|
|
| IIIA | Any size tumor (includes invading tumors) |
|
|
| IIIB | Any size tumor (includes invading tumors) | Postive for:
|
|
| IV | Any size tumor (includes invading tumors) |
|
