ON THIS PAGE: You will find information about the number of people who are diagnosed with this type of sarcoma each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.
Before HIV/AIDS was widespread, Kaposi sarcoma was extremely rare in the United States, with about 2 people diagnosed for every 1 million people. By the early 1990s, that rate had increased to about 47 cases per 1 million people, most of which involved people with HIV/AIDS.
This number has significantly decreased in recent years to about 6 cases per 1 million people because of more effective treatments for HIV/AIDS. Men are nearly 10 times more likely than women to be diagnosed with the disease. Incidence rates are highest in black people and Hispanic people.
About 1 in 200 transplant recipients in the United States develops Kaposi sarcoma.
The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. When HIV and AIDS first became widespread, the 5-year survival rate of people with Kaposi sarcoma was less than 10%. Now the 5-year survival rate for people with both HIV and Kaposi sarcoma is 73%, but even this is probably an underestimate.
More effective treatments for HIV/AIDS are improving the survival rate both by treating the infections associated with HIV/AIDS and the Kaposi sarcoma. Other factors also affect survival, including the risk grouping of Kaposi sarcoma.
It is important to remember that statistics on the survival rates for people with Kaposi sarcoma are an estimate. The estimate comes from annual data based on the number of people with this cancer in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. People should talk with their doctor if they have questions about this information.
