Kaposi Sarcoma Treatment (PDQ®): Treatment - Patient Information [NCI] - General Information About Kaposi Sarcoma

continued...

After Kaposi sarcoma has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body.

The following tests and procedures may be used to find out if cancer has spread to other parts of the body:

  • 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, liver, and spleen, 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. This imaging test checks for signs of cancer in the lung, liver, and spleen.
  • CD34lymphocyte count: A procedure in which a blood sample is checked to measure the amount of CD34 cells (a type of white blood cell). A lower than normal amount of CD34 cells can be a sign the immune system is not working well.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

  • The type of Kaposi sarcoma.
  • The general health of the patient, especially the patient's immune system.
  • Whether the cancer has just been diagnosed or has recurred (come back).
