Ann Arbor staging
Ann Arbor staging 은 림프종의 병기를 위해 주로 사용되고, AJCC Manual for Staging of Cancer에서 정의된 체계이다. 처음에는 Hodgkin’s 질병을 위해 개발된 이 병기 체계는 나중에 Non-Hodgkin’s 질병을 포함하도록 확장되었다.
Hodgkin’s disease에서 extranodal 은 드물고 전신증상은 흔하며 예후에 중요한 영향을 미친다. 이 체계는 Hodgkin’s disease에는 유용하지만, Non-Hodgkin’s lymphoma에는 덜 유용하다
| Stage | Definition |
|---|---|
| I | Involvement of a single lymph node region or lymphoid structure(e,g., spleen, thymus, Waldeyer’s ring) |
| II | Involvement of two or more lymph node regions on the same side of the diaphragm(the mediastinum is a single site; hilar lymph nodes should be considered “ lateralized” and, when involved on both sides, constitute stage ll disease) |
| III | Involvement of lymph node regions of lymphoid structures on both sides of the diaphragm |
| III1 | Subdiaphragmatic involvement limited to spleen, splenic hilar nodes, celiac nodes, or portal nodes |
| III2 | Subdiaphragmatic involvement includes paraaotic, iliac, or mesenteric nodes plus structures in III1 |
| IV | Involvement of extranodal site(s) beyond that designated as “E” More than one extranodal deposit at any location Any involvement of liver or bone marrow |
| A | No symptoms |
| B | Unexplained weight loss of >10% of the body weight during the 6 months before staging investigation Unexplained, persistent, of recurrent fever with temperatures > 38℃ during the previous month Recurrent drenching night sweats during the previous month |
| E | Localized, solitary involvement of extralymphatic tissue, excluding liver and bone marrow |
