Kaposi’s sarcoma is a rare cancer that grows on the skin as well as in the lymph nodes, lungs, and other regions of the body, and patients with the illness have limited treatment options. If the disease is associated with HIV infection, antiretroviral therapy is the first-line treatment, augmented with traditional chemotherapy.

What is Kaposi's sarcoma in HIV?
Kaposi's sarcoma is one of the main types of cancer to affect people with HIV. It can progress very quickly if it is not treated. It can usually be treated very effectively by taking HIV medicine known as combination antiretroviral therapy (cART). This prevents HIV multiplying and allows the immune system to recover.
Does chemotherapy cure Kaposi sarcoma?
More than half of KS patients treated with chemo will improve, but KS generally doesn't go away completely. Sometimes chemo can be stopped as long as lesions are not causing problems or increasing in size and number. If the KS starts to get worse, treatment may be restarted.
How do you treat KS lesions?
Topical treatment This type of treatment puts medicine directly on the lesion. For example, alitretinoin, a retinoid drug related to vitamin A, is available as a gel that can be used to treat KS skin lesions. When it is placed on a KS lesion 2 to 4 times a day, it makes it get smaller or go away in 1 to 3 months.
Is Kaposi sarcoma curable?
This is a very real concern for those who have KS, since treatments often do not cure the disease. For many people with KS, the cancer never goes away completely. Some people may get regular treatments with chemotherapy, radiation therapy, or other therapies to try to help keep the cancer in check.
Where does Kaposi sarcoma first appear?
Kaposi sarcoma generally develops in tissue located below the skin's surface or in the lining of the mouth, nose, or anus. Areas where tissues have abnormal changes are known as Kaposi sarcoma lesions. These lesions usually appear on the skin as raised blotches or nodules.

How can Kaposi's sarcoma be prevented?
Although there is no proven way to completely prevent Kaposi sarcoma, you can significantly lower your risk by avoiding the known risk factors for HIV/AIDS, especially by avoiding risky practices, such as having unprotected sex and using intravenous (IV) needles that have been used by someone else.
What is vinblastine made of?
Vinblastine belongs to a class of chemotherapy drugs called alkaloids. Plant alkaloids are made from plants. The vinca alkaloids are made from the periwinkle plant (catharanthus rosea). The plant alkaloids are cell-cycle specific.
Do Kaposi sarcoma lesions go away?

Is cryosurgery considered surgery?
Cryosurgery is a type of surgery that involves the use of extreme cold to destroy abnormal tissues, such as tumors. The surgery most often involves the use of liquid nitrogen, although carbon dioxide and argon may also be used.
How to evaluate Kaposi sarcoma?
The staging evaluation of patients with classic Kaposi sarcoma (KS) should be individualized. The advanced age of most of the patients, localized nature of the tumor, rarity of visceral involvement, and usually indolent course of the disease should temper the extent of the evaluation. A careful examination of the skin and lymph nodes is sufficient in most cases. For the rare patient with rapidly progressive tumor or signs or symptoms of visceral involvement, appropriate evaluation is indicated. No universally accepted classification is available for epidemic KS. Staging schemes that incorporate laboratory parameters as well as clinical features have been proposed. Since most patients with epidemic KS do not die from the disease, factors besides tumor burden are apparently involved in survival.
What is the AIDS Clinical Trials Group?
The AIDS Clinical Trials Group (ACTG) Oncology Committee has published criteria for the evaluation of epidemic KS. [ 1] The staging system incorporates measures of extent of disease, severity of immunodeficiency, and presence of systemic symptoms. As shown in Table 1 below, the ACTG criteria categorizes the extent of the tumor as localized or disseminated, the CD4 cell number as high or low, and a systemic illness as absent or present.

Although the histopathology of the different types of the Kaposi tumor is essentially identical in all of these groups, the clinical manifestations and course of the disease differ dramatically. [ 2] Human herpes virus type 8 , also known as Kaposi sarcoma herpes virus, was identified in KS tissue biopsies from virtually all patients with classic, transplant-related, and AIDS-associated KS but was absent from noninvolved tissue. [ 2]
Is a KS a primary malignancy?
Classic Kaposi sarcoma (KS) usually is limited to the skin and has an indolent course. Patients with this tumor are predisposed to the development of a second primary malignancy, and the treating physician should consider this factor when arranging a schedule of follow-up treatment for the patient.
Where do systemic lesions develop?
In long-standing cases, systemic lesions can develop along the gastrointestinal tract, in lymph nodes, and in other organs. The visceral lesions are generally asymptomatic and are most often discovered only at autopsy, though clinically, gastrointestinal bleeding can occur.
Does HAART reduce HIV?
The introduction of highly active antiretroviral therapy (HAART) has delayed or prevented the emergence of drug-resistant HIV strains, profoundly decreased viral load, led to increased survival, and lessened the risk of opportunistic infections. [ 4] The use of HAART has been associated with a sustained and substantial decline in KS incidence in multiple large cohorts. [ 5 - 7] KS can still appear during HAART with complete suppression of HIV; most cases in the United States occur in patients with high CD4 counts and ongoing HAART. [ 8]

The British HIV Association recommends that people with cancer and HIV should be treated at hospitals with a lot of experience of treating cancer in people with HIV. You have the best chance of a good outcome if you go to a hospital with this experience.
Why does KS flare up after HIV treatment?
This may be due to a condition called immune reconstitution inflammatory syndrome (IRIS).
How often do you give liposomal doxorubicin?
They are usually given through a drip into a vein every two to three weeks for a few months. They have fewer side-effects than some older chemotherapy drugs, but can still cause reductions in the number of white blood cells, making you more vulnerable to infections. If these drugs are not suitable for you, BHIVA recommends paclitaxel as an alternative.
Why does KS cause low CD4?
In fact, the illness is thought to be caused by an improvement in the immune system’s ability to detect or mount a response to HHV-8 or KS.

How to diagnose Kaposi's sarcoma?
Your doctor may diagnose Kaposi’s sarcoma just by looking at your skin. To confirm it, they may take a sample of tissue from a spot and look at it under a microscope, which is called a biopsy.

If you’re having stomach trouble or belly pain, your doctor might want to look in your stomach with a lighted tube called an endoscope or in your intestines with a colonoscope. 3 Bronchoscopy. If you have trouble breathing, they might look into your airways with a thin tube called a bronchoscope. 4 Imaging tests. A CT scan or an X-ray can tell whether the cancer has spread to your lungs, your lymph nodes, or other parts of your body.
