Stages of Adult Non-Hodgkin Lymphoma
Key Points for This Section
- After adult non-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.
- There are three ways that cancer spreads in the body.
- Stages of adult non-Hodgkin lymphoma may include E and S.
- The following stages are used for adult non-Hodgkin lymphoma:
- Adult non-Hodgkin lymphomas are also described based on how fast they grow and where the affected lymph nodes are in the body.
- There is no standard staging system for Waldenström macroglobulinemia.
The process used to find out the type of cancer and if cancer cells have 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 of the disease in order to plan treatment. The following tests and procedures may be used in the staging process:
- Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following:
- The number of red blood cells and platelets.
- The number and type of white blood cells.
- The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
- The portion of the blood sample made up of red blood cells.
- Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that makes it.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the lung, lymph nodes, and liver, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
- MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for signs of cancer.
For pregnant women with non-Hodgkin lymphoma, staging tests that protect the fetus from the harms of radiation are used. These include MRI, bone marrow aspiration and biopsy, lumbar puncture, and ultrasound, which do not use radiation. An ultrasound exam is a procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
- 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.
Adult non-Hodgkin 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.
- 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: 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 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 III: Cancer is found in lymph node groups above and below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen).
- Stage IIIE: Cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area.
- Stage IIIS: Cancer is found in lymph node groups above and below the diaphragm, and in the spleen.
- Stage IIIE+S: Cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area, and in the spleen.
- is found throughout one or more organs that are not part of a lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen), and may be in lymph nodes near those organs; or
- is found in one organ that is not part of a lymphatic area and has spread to organs or lymph nodes far away from that organ; or
- is found in the liver, bone marrow, cerebrospinal fluid (CSF), or lungs (other than cancer that has spread to the lungs from nearby areas).
- Indolent lymphomas: These tend to grow and spread slowly and have few symptoms.
- Aggressive lymphomas: These grow and spread quickly and have severe symptoms. Lymphoblastic lymphoma, diffuse small noncleaved cell lymphoma /Burkitt lymphoma, and mantle cell lymphoma are three types of aggressive adult non-Hodgkin lymphoma. Aggressive lymphomas are seen more often in patients who are HIV -positive (AIDS -related lymphoma).
- Contiguous lymphomas: Lymphomas in which the lymph nodes with cancer are next to each other.
- Noncontiguous lymphomas: Lymphomas in which the lymph nodes with cancer are not next to each other, but are on the same side of the diaphragm.
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with Waldenström macroglobulinemia. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI Web site.
