Purpose of the review—Given the recent availability of antiretroviral therapy (ART) in
resource-limited settings and the significant burden exacted by Kaposi’s sarcoma (KS) in these
areas, we reviewed data regarding the impact of ART on KS incidence. We summarized the
sizeable literature in resource-rich settings as well emerging data from resource-limited regions.
Importantly, we delineated ways impact can be defined, including a) individual patient-level
effectiveness; b) population-level effectiveness; c) change in population-level incidence; and d)
residual risk of KS.
Recent findings—In resource-rich settings, there are now ample data demonstrating beneficial
individual patient-level and population-level effects of ART on KS incidence. There is, however,
considerable variability between studies and important methodologic shortcomings. Data from
resource-limited settings are much more limited; while they preliminarily indicate individual
patient-level effectiveness, they do not yet provide insight on population-level effects.
Summary—ART has had a substantial impact on KS incidence in resource-rich settings, but
more attention is needed on validly quantifying this effect in order to determine whether additional
interventions are needed. Emerging data from resource-limited regions also suggests beneficial
impact of ART on KS incidence, but — given the scope of KS in these settings — more data are
needed to understand the breadth and magnitude of the effect. |
