5. Staging System


The American Joint Committee on Cancer (AJCC)/International Union against Cancer (UICC) stage classification system stresses the importance of the malignancy grade in sarcoma. In general, in addition to grading, other prognostic factors are tumor size and tumor depth for limb sarcomas. Tumor site, resectability and presence of metastases are also important.

American Joint Committee on Cancer (AJCC)/International Union against Cancer (UICC) TNM staging system:

Primary tumour (T)
TX

T0
No evidence of primary tumour 
T1
Tumour 5 cm or less in greatest dimensiona
T1a

T1b
Deep tumour
T2
Tumour >5 cm in greatest dimensiona
T2a
Superficial tumour
T2b
Deep tumour 

Regional lymph nodes (N) 
NX
Regional lymph nodes cannot be assessed
N0
No regional lymph node metastasis 
N1b
Regional lymph node metastasis

Distant metastasis (M) 
M0
No distant metastasis
M1
Distant metastasis
