Table 1. Lugano Classification for Hodgkin and Non-Hodgkin Lymphomaa

Stage Stage DescriptionIllustration
Limited stage
IInvolvement of a single lymphatic site (i.e., nodal region, Waldeyer’s ring, thymus, or spleen).
Stage I adult lymphoma; drawing shows cancer in one lymph node group and in the spleen. Also shown are the Waldeyer’s ring and the thymus. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.
IESingle extralymphatic site in the absence of nodal involvement (rare in Hodgkin lymphoma).
IIInvolvement of two or more lymph node regions on the same side of the diaphragm.
Stage II adult lymphoma; drawing shows cancer in two lymph node groups above the diaphragm and below the diaphragm. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.
IIEContiguous extralymphatic extension from a nodal site with or without involvement of other lymph node regions on the same side of the diaphragm.
Stage IIE adult lymphoma; drawing shows cancer that has spread from a group of lymph nodes to a nearby area. Also shown is a lung and the diaphragm. An inset shows a lymph node with a lymph vessel, an artery, and a vein. Cancer cells are shown in the lymph node.
II bulkybStage II with disease bulk.c
Advanced stage
IIIInvolvement of lymph node regions on both sides of the diaphragm; nodes above the diaphragm with spleen involvement.
Stage III adult lymphoma; drawing shows the right and left sides of the body. The right side of the body shows cancer in a group of lymph nodes above the diaphragm and below the diaphragm. The left side of the body shows cancer in a group of lymph nodes above the diaphragm and cancer in the spleen.
IVDiffuse or disseminated involvement of one or more extralymphatic organs, with or without associated lymph node involvement; or noncontiguous extralymphatic organ involvement in conjunction with nodal stage II disease; or any extralymphatic organ involvement in nodal stage III disease. Stage IV includes any involvement of the CSF, bone marrow, liver, or multiple lung lesions (other than by direct extension in stage IIE disease).
Stage IV adult lymphoma; drawing shows four panels: (a) the top left panel shows cancer in the liver; (b) the top right panel shows cancer in the left lung and in two groups of lymph nodes below the diaphragm; (c) the bottom left panel shows cancer in the left lung and in a group of lymph nodes above the diaphragm and below the diaphragm; and (d) the bottom right panel shows cancer in both lungs, the liver, and the bone marrow (pullout). Also shown is primary cancer in the lymph nodes and a pullout of the brain with cerebrospinal fluid (in blue).
Note: Hodgkin lymphoma uses A or B designation with stage group. A/B is no longer used in NHL.

CSF = cerebrospinal fluid; CT = computed tomography; DLBCL = diffuse large B-cell lymphoma; NHL = non-Hodgkin lymphoma.

bStage II bulky may be considered either early or advanced stage based on lymphoma histology and prognostic factors.

cThe definition of disease bulk varies according to lymphoma histology. In the Lugano classification, bulk ln Hodgkin lymphoma is defined as a mass greater than one-third of the thoracic diameter on CT of the chest or a mass >10 cm. For NHL, the recommended definitions of bulk vary by lymphoma histology. In follicular lymphoma, 6 cm has been suggested based on the Follicular Lymphoma International Prognostic Index-2 and its validation. In DLBCL, cutoffs ranging from 5 cm to 10 cm have been used, although 10 cm is recommended.
