Long-term incidence of cervical cancer in women with human immunodeficiency virus

Abstract

BACKGROUND: The objective of this study was to estimate the incidence of invasive cervical cancer (ICC) in women with human immunodeficiency virus (HIV) and compare it with the incidence in HIV-uninfected women. METHODS: In a cohort study of HIV-infected and uninfected women who had Papanicolaou tests obtained every 6 months, pathology reports were retrieved for women who had biopsy results or a self- report of ICC. Histology was reviewed when reports confirmed ICC. Incidence rates were calculated and compared with those in HIV-negative women. RESULTS: After a median follow-up of 10.3 years, 3 ICCs were confirmed in HIV-seropositive women, and none were confirmed in HIV-seronegative women. The ICC incidence rate was not found to be associated significantly with HIV status (HIV-negative women [0 of 100,000 person-years] vs HIV-positive women [21.4 of 100,000 person-years]; P = .59). A calculated incidence rate ratio standardized to expected results from the Surveillance Epidemiology and End Results database that was restricted to HIV-infected Women's Interagency HIV Study participants was 1.32 (95% confidence interval, 0.27-3.85; P = 0.80). CONCLUSIONS: Among women with HIV in a prospective study that incorporated cervical cancer prevention measures, the incidence of ICC was not significantly higher than that in a comparison group of HIV-negative women.
