AIDS-Related Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for AIDS-Related Lymphoma
Although stage is important in selecting the treatment of patients with non-Hodgkin lymphoma (NHL) who do not have AIDS, the majority of patients with AIDS-related lymphomas have far-advanced disease.

|I||Involvement of a single lymphatic site (i.e., nodal region, Waldeyer ring, thymus or spleen) (I).|
|Localized involvement of a single extralymphatic organ or site in the absence of any lymph node involvement (IE) (rare in Hodgkin lymphoma).|
|II||Involvement of two or more lymph node regions on the same side of the diaphragm (II).|
|Localized involvement of a single extralymphatic organ or site in association with regional lymph node involvement with or without involvement of other lymph node regions on the same side of the diaphragm (IIE). The number of regions involved may be indicated by a subscript Arabic numeral, for example, II3|
|III||Involvement of lymph node regions on both sides of the diaphragm (III), which also may be accompanied by extralymphatic extension in association with adjacent lymph node involvement (IIIE) or by involvement of the spleen (IIIS) or both (IIIE, IIIS). Splenic involvement is designated by the letter S.|
|IV||Diffuse or disseminated involvement of one or more extralymphatic organs, with or without associated lymph node involvement.|
|Isolated extralymphatic organ involvement in the absence of adjacent regional lymph node involvement, but in conjunction with disease in distant site(s). Stage IV includes any involvement of the liver or bone marrow, lungs (other than by direct extension from another site), or cerebrospinal fluid.|
The Ann Arbor staging system is commonly used for patients with NHL.[1,2] In this system, stage I, II, III, and IV NHL can be subclassified into A and B categories: B for those with well-defined generalized symptoms and A for those without. The B designation is given to patients with any of the following symptoms:
- Unexplained loss of more than 10% of body weight in the 6 months before diagnosis.
- Unexplained fever with temperatures higher than 38° C.
- Drenching night sweats. (Refer to the PDQ summary on Hot Flashes and Night Sweats for more information.)
