There are different types of treatment for patients with Kaposi sarcoma.
Different types of treatments are available for patients with Kaposi sarcoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Purpose of This Summary
This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about endometrial cancer screening. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.

Treatment of epidemic Kaposi sarcoma combines treatment for Kaposi sarcoma with treatment for AIDS.
For the treatment of epidemic Kaposi sarcoma, highly active antiretroviral therapy (HAART) is used to slow the progression of AIDS. HAART may be combined with anticancer drugs and medicines that prevent and treat infections.
Four types of standard treatment are used to treat Kaposi sarcoma:
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer being treated.
Certain types of external radiation therapy are used to treat Kaposi sarcoma lesions. Photon radiation therapy treats lesions with high-energy light. Electron beam radiation therapy uses tiny negatively charged particles called electrons.
The following surgical procedures may be used for Kaposi sarcoma to treat small, surface lesions:
Local excision: The cancer is cut from the skin along with a small amount of normal tissue around it.
Electrodesiccation and curettage: The tumor is cut from the skin with a curette (a sharp, spoon-shaped tool). A needle-shaped electrode is then used to treat the area with an electric current that stops the bleeding and destroys cancer cells that remain around the edge of the wound. The process may be repeated one to three times during the surgery to remove all of the cancer.
Cryosurgery: A treatment that uses an instrument to freeze and destroy abnormal tissue. This type of treatment is also called cryotherapy.
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). To treat local Kaposi sarcoma lesions, such as in the mouth, anticancer drugs may be injected directly into the lesion (intralesional chemotherapy). Sometimes the chemotherapy is given as a topical agent (applied to the skin as a gel.) The way the chemotherapy is given depends on the type of cancer being treated.
