NCIt definition : The Ann Arbor system classifies lymphoma into four stages based on anatomic lymph
nodal group involvement. Disease confined to one nodal group or location defines stage
I. Disease limited to one side of the diaphragm, (the muscle separating the chest
from the abdomen), defines stage II. Stage III patients have disease on both sides
of the diaphragm and stage IV patients once again have disseminated disease. Consideration
of involvement of the liver, spleen, and bone marrow are also considered in this system.
Finally, the stage is subdivided into categories of A and B depending on the presence
of symptoms of itching, weight loss, fever, and night sweats. Those having symptoms
receive the designation B and have a worse prognosis.;
