    AIDS-Related Lymphoma Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of AIDS-Related Lymphoma

    continued...

    There are three ways that cancer spreads in the body.

    Cancer can spread through tissue, the lymph system, and the blood:

    • Tissue. The cancer spreads from where it began by growing into nearby areas.
    • Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
    • Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

    Stages of AIDS-related lymphoma may include E and S.

    AIDS-related lymphoma may be described as follows:

    • E: "E" stands for extranodal and means the cancer is found in an area or organ other than the lymph nodes or has spread to tissues beyond, but near, the major lymphatic areas.
    • S: "S" stands for spleen and means the cancer is found in the spleen.

    The following stages are used for AIDS-related lymphoma:

    Stage I

    Stage I AIDS-related lymphoma. Cancer is found in one lymphatic area (lymph nodes, tonsils, thymus, or spleen). In stage IE (not shown), cancer is found in one organ or area outside the lymph nodes.

    Stage I AIDS-related lymphoma is divided into stage I and stage IE.

    Stage I: Cancer is found in one lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen).
    Stage IE: Cancer is found in one organ or area outside the lymph nodes.

    Stage II

    Stage II AIDS-related lymphoma is divided into stage II and stage IIE.

    • Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen).

      Stage II AIDS-related lymphoma. Cancer is found in two or more lymph node groups, and both are either above (a) or below (b) the diaphragm.
    • Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm. Cancer is also found outside the lymph nodes in one organ or area on the same side of the diaphragm as the affected lymph nodes.

      Stage IIE AIDS-related lymphoma. Cancer is found in one or more lymph node groups either above or below the diaphragm and outside the lymph nodes in an organ or area on the same side of the diaphragm as the lymph nodes with cancer (a).
