Localized only
Nodal Lymphomas
- Single lymph node region involved
- Involvement of multiple nodal chains in the SAME lymph node region
Extranodal Lymphomas
- Single extralymphatic site
+ WITHOUT nodal involvement (see code 2 for WITH nodal involvement)
- Multifocal involvement of one extralymphatic organ/site (EXCEPT multifocal lung involvement or any liver involvement, see code 7)
+ WITHOUT nodal involvement (see code 7 for WITH nodal involvement) |

Bulky disease present
Nodal Lymphomas
- Two or more lymph node regions involved SAME side of diaphragm
- Contiguous extension between extralymphatic sites and regional nodes
+ WITH or WITHOUT involvement of other nodal regions on SAME side of diaphragm
Extranodal Lymphomas

- Distant involvement
+ Diffuse or disseminated involvement of ONE OR MORE extralymphatic organ(s)/site(s) WITH or WITHOUT nodal involvement
