Malignancies, particularly Kaposi's sarcoma and non-Hodgkin's lymphoma
(NHL), are associated with human immunodeficiency virus (HIV) infecti
on, Cancer incidence among 1,073 asymptomatic HIV-infected individuals
from the Pulmonary Complications of HIV infection Study cohort, perso
ns from six states followed from 1988 to 1994, was examined, Total can
cer incidence was 3.99/100 person-years; for Kaposi's sarcoma, inciden
ce was 2.64 cases/100 person-years, and for NHL, it was 1.18 cases/100
person-years. Total cancer (n = 156 cases) was higher among nonblacks
than among blacks (rate ratio = 2.8, 95% confidence interval 1.3-6.1)
, with similar results far Kaposi's sarcoma and NHL. The rate of lung
cancer (n = 5) among white, homosexual/bisexual males was 0.18 per 100
person-years, suggesting a high risk of lung cancer.
