Overview
The staging of thymic carcinoma is based on the Masoka and GETT staging system.
Masaoka TNM Staging (1999)
 |
Original Masaoka Staging (1991)
- Stage I - Macroscopically and microscopically completely encapsulated
- Stage II - Macroscopic invasion into surrounding fatty tissues or mediastinal pleura or microscopic invasion into the capsule
- Stage III - Macroscopic invasion into adjacent organs or intrathoracic metastases
- Stage IVA - Pleural or pericardial implants/dissemination
- Stage IVB - Nodal or hematogenous metastases
GETT Staging
- Stage IA - Encapsulated, completely resected
- Stage IB - Macroscopically completely resected but suspicion of mediastinal adhesions or potential capsular invasion at surgery
- Stage II - Invasive tumor, completely resected
- Stage IIIA - Invasive tumor, subtotal resection
- Stage IIIB - Invasive tumor, biopsy alone
- Stage IVa - Supraclav or pleural met
- Stage IVb - Distant metastases[1]
