Ann Arbor Staging for Lymphoma

Staging system for Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) based on the number and location of involved lymph node regions and extranodal sites. Guides treatment planning.

Score interpretation

Stage I — Localised Disease 1

Stage I: Single nodal region or extralymphatic site. Excellent prognosis in HL.

→ HL: ABVD × 2–4 cycles + radiotherapy (involved-field). NHL: RCHOP × 3–4 cycles ± radiotherapy. PET-CT for response assessment. Haematology/lymphoma MDT.

Stage II — Regional Disease 2

Stage II: Multiple nodal regions same side of diaphragm. Good prognosis overall.

→ HL: ABVD × 4 cycles ± radiotherapy depending on response. NHL: R-CHOP × 6 cycles standard. PET-CT interim and end-of-treatment. Lymphoma MDT.

Stage III — Disseminated Nodal Disease 3

Stage III: Both sides of diaphragm involved. Advanced disease.

→ HL: ABVD or BEACOPP × 6 cycles depending on risk. NHL: R-CHOP × 6 cycles. CNS prophylaxis if indicated. ASCT in relapse setting. Clinical trial.

Stage IV — Disseminated / Extralymphatic Disease 4

Stage IV: Disseminated involvement of extralymphatic organs. Advanced stage.

→ HL: Escalated BEACOPP or ABVD depending on fitness. NHL: R-CHOP × 6–8 cycles. ASCT if eligible. Palliative care if not fit for intensive therapy. Clinical trial enrolment encouraged.
