What are the stages of Kaposi sarcoma?

Unlike many other types of cancer, Kaposi sarcoma doesn't really have an official system of staging. This is because in Kaposi sarcoma, tumors don't necessarily grow and spread throughout the body the same way they do in other types of cancer. Also, since it's so closely related to other immune problems like AIDS, many other factors can come into play when determining the extent of the cancer. For this reason, many people use the AIDS Clinical Trials Group system to determine the stage, or extent, of Kaposi sarcoma. This system considers three factors that are each broken down into subgroups of either 0 (good risk) or 1 (poor risk). These factors are the tumor, the immune system, and systemic, or whole body, involvement. After analyzing those factors, doctors may be able to give a more accurate prognosis for each case of Kaposi sarcoma.
