Ann Arbor classification

A method of deciding on the stage to which any case of HODGKIN'S DISEASE has progressed. Staging is important in deciding the best treatment and in determining the outlook (prognosis). In Stage I only one lymph node or one extra-lymphatic site is involved. In Stage IV, tissues such as bone marrow and liver are affected.
