What are different stages of Adult Hodgkin Lymphoma?

After adult Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body.

The process used to find out if cancer has spread within the lymph system or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage to plan treatment. The results of the tests and procedures done to diagnose and stage Hodgkin lymphoma are used to help make decisions about treatment.

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.

The following stages are used for adult Hodgkin lymphoma:

Stage I

Stage I adult Hodgkin lymphoma is divided into stages I and IE.

• In stage I, cancer is found in one of the following places in the lymph system:
  • One or more lymph nodes in a group of lymph nodes.
  • Waldeyer's ring.
  • Thymus.
  • Spleen.
• In stage IE, cancer is found in one area outside the lymph system.

Stage II

Stage II adult Hodgkin lymphoma is divided into stages II and IIE.

• In stage II, cancer is found in two or more groups of lymph nodes that are either above the diaphragm or below the diaphragm.
• In stage IIE, cancer has spread from a group of lymph nodes to a nearby area that is outside the lymph system. Cancer may have spread to other lymph node groups on the same side of the diaphragm.

In stage II, the term bulky disease refers to a larger tumor mass. The size of the tumor mass that is referred to as bulky disease varies based on the type of lymphoma.

Stage III

In stage III adult Hodgkin lymphoma, cancer is found:

• in groups of lymph nodes both above and below the diaphragm; or
• in lymph nodes above the diaphragm and in the spleen.

Stage IV

In stage IV adult Hodgkin lymphoma, cancer:

• has spread throughout one or more organs outside the lymph system; or
• is found in two or more groups of lymph nodes that are either above the diaphragm or below the diaphragm and in one organ that is outside the lymph system and not near the affected lymph nodes; or
• is found in groups of lymph nodes both above and below the diaphragm and in any organ that is outside the lymph system; or
• is found in the liver, bone marrow, more than one place in the lung, or cerebrospinal fluid (CSF). The cancer has not spread directly into the liver, bone marrow, lung, or CSF from nearby lymph nodes.
