Overview
The staging of liposarcoma is based on the TNM classification, which includes primary tumor spread, lymph node involvement, and presence of metastasis.
Staging
|
|
| Primary Tumor (T)
|
|---|
| Tx
|
Tumor cannot be assessed.
|
| T0
|
No evidence of primary tumor.
|
| T1
|
Tumor ≤ 5 cm
|
- T1a
|
Superficial tumor (not invading the fascia)
|
- T1b
|
Deep tumor
|
| T2
|
Tumor > 5 cm
|
- T2a
|
Superficial tumor (not invading the fascia)
|
- T2b
