- I: Completely encapsulated
- IIA: Microscopic invasion through the capsule into surrounding fatty tissue
- IIB: Macroscopic invasion into capsule
- III: Macroscopic invasion into adjacent organs
- IVA: Pleural or pericardial implants
- IVB: Lymphogenous or hematogenous metastasis to distant (extrathoracic) sites
