Hodgkin lymphoma staging
A commonly adopted staging system for Hodgkin lymphoma is the Cotswold's modification of the original Ann arbor staging system.
Accurate CT staging has been shown to have a significant impact on treatment and eventual clinical outcome.
stage I: one nodal group:
- stage IE: one extra nodal site
stage II: two or more nodal groups, same side of diaphragm
- stage IIE: one nodal group and one extranodal site, both on the same side of the diaphragm
stage III: nodal groups on both sides of the diaphragm
- stage IIIS(1): nodal groups above diaphragm and splenic involvement
- stage IIIE(2): nodal groups above diaphragm and extra nodal site below diaphragm
- stage IV: one or more extra lymphatic organ (e.g. lung, bone) +/- any nodal involvement
Additional staging variables
- X: bulky nodal disease: nodal mass >1/3 of intra thoracic diameter or 10 cm in dimension
- A: asymptomatic
- B: presence of B symptoms (fever, night sweats and weight loss)
