What is the prognosis for kaposi sarcoma?

http://www.nlm.nih.gov/medlineplus/kapos...

Kaposi's sarcoma (which is not a true sarcoma) is a cancer of the lymphatic endothelium. It is caused by the human herpes virus 8 (HHV-8, also known as Kaposi's sarcoma associated virus). HHV-8 is most likely to cause aggressive KS if there are significant suppression of cell-mediated immunity. Other factors such as age, genetics, and possibly sex hormones are also factors in the tumour's development.

There are four different forms of the disease, each of which has a different prognosis:

1. Classic KS - this occurs mainly in elderly males of Eastern European Jewish heritage. The course of the disease is relatively indolent, and most sufferers end up dying from something else.

2. Endemic KS - this occurs mainly in subsaharan Africa, and is sometimes relatively benign and sometimes more aggressive. It most commonly affects boys and men. It is NOT related to HIV infection, although HIV-related KS also occurs in that region.

3. Transplant related KS - this is related to the T-cell suppression by anti-rejection drugs, particularly cyclosporin, and is a serious if uncommon complication of the use of these drugs.

4. Epidemic or AIDS related KS - related to severe T-cell suppression caused by HIV infection. This is frequently a very aggressive form of the tumour.

it is treatable although it means you have cancer and have reached the stage of AIDS.
