 AB    A decline in the proportion of Kaposi's sarcoma among AIDS cases since
       the 1980s has been attributed to changes in sexual behavior among
       homosexual men and a decreasing exposure to a hypothesized Kaposi's
       sarcoma cofactor. Recent studies have shown that the incidence rate of
       Kaposi's sarcoma has remained relatively stable, which seems to argue
       against the hypothesis of a declining exposure to the putative cofactor.
       To examine this paradox, we evaluated the incidence of Kaposi's sarcoma,
       using Cox proportional hazard analyses, and performed a simulation to
       compare incidences of different AIDS outcomes among 407 homosexual men
       with documented dates of seroconversion. Our data show that men who
       seroconverted early in the epidemic did not progress faster to Kaposi's
       sarcoma than men who seroconverted more recently. A lower incidence rate
       of Kaposi's sarcoma would be expected among the latter group if exposure
       to the hypothesized cofactor is decreasing over time. The percentage of
       Kaposi's sarcoma among incident AIDS cases decreased over the years
       following seroconversion, but not over calendar time. This study
       demonstrates that the decline in the proportion of Kaposi's sarcoma
       among AIDS cases should not be interpreted as a decline in the incidence
       of Kaposi's sarcoma and that there is no evidence that a hypothesized
       Kaposi's sarcoma cofactor is declining over calendar time.
