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
Deep tumor

Lymph Nodes (N)
NX Lymph nodes cannot be assessed.
N0 No regional lymph node involvement.
N1 Regional lymph node involvement.

Metastasis (M)
M0 No distant metastasis
M1 Distant metastasis
