AIDS-Related Lymphoma Treatment

Stages of AIDS-Related Lymphoma

After AIDS-related 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 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 in order to plan treatment, but AIDS-related lymphoma is usually advanced when it is diagnosed. The following tests and procedures may be used in the staging process:

There are three ways that cancer spreads in the body.

The three ways that cancer spreads in the body are:

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.

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

AIDS-related lymphoma may be described as follows:

The following stages are used for AIDS-related lymphoma:

Stage I

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

Stage II

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

Stage III

Stage III AIDS-related lymphoma is divided into stage III, stage IIIE, stage IIIS, and stage IIIS+E.

Stage IV

In stage IV AIDS-related lymphoma, the cancer either:

Patients who are infected with the Epstein-Barr virus or whose AIDS-related lymphoma affects the bone marrow have an increased risk of the cancer spreading to the central nervous system (CNS).

For treatment, AIDS-related lymphomas are grouped based on where they started in the body, as follows:

Peripheral/systemic lymphoma

Lymphoma that starts in lymph nodes or other organs of the lymph system is called peripheral/systemic lymphoma. The lymphoma may spread throughout the body, including to the brain or bone marrow.

Primary CNS lymphoma

Primary CNS lymphoma starts in the central nervous system (brain and spinal cord). Lymphoma that starts somewhere else in the body and spreads to the central nervous system is not primary CNS lymphoma.
