AB AIDS is associated with a high risk of certain malignancies, notably
Kaposi's sarcoma (KS) and B-cell non-Hodgkin's lymphoma (NHL). The
pathogenesis of these malignancies is not fully understood. One
mechanism of malignant transformation recently described in colon
tumorigenesis results from defects in DNA mismatch repair, manifest as
widespread microsatellite instability. We demonstrate a high rate of
microsatellite instability in KS and aggressive lymphomas obtained from
HIV-infected patients, whereas there is no evidence of instability in
similar lesions from HIV-negative patients. Further elucidation of the
underlying mechanisms responsible for HIV-associated instability in
primary tumours may provide insight into the pathogenesis of these
AIDS-related neoplasms.
