People need to be aware of this when symptoms present. You mentioned that many people are living years longer than was initially expected with HIV infection. We're not sure. The incidence of KS has fallen dramatically. A study done a year ago showed how rapidly the incidence of KS had declined since 1990, particularly since 1995.
Lymphoma is a little bit different.
In many parts of the country, lymphoma rates have increased or stayed the same. In King County, lymphoma rates decreased between 1995 and 1997, but that has not been the norm. And although it hasn't been reported well yet, New York is seeing a resurgence of lymphomas, at least in clinics with a large number of HIV patients. The dividing of cells with mitogenic stimulation is never really taken away. It is conceivable that lymphoma rates can take a swing up.
