HIV infection as a risk factor for cervical cancer and cervical intraepithelial neoplasia in Senegal.
Cervical cancer is the second leading cause of cancer mortality in women worldwide, and the leading cause in Africa. There is uncertainty in the role of HIV infection as a risk factor for invasive and preinvasive cervical lesions, particularly in African populations. In a case-control study in Dakar, Senegal, we studied 150 women with invasive cervical cancer (ICC), 92 with cervical intraepithelial neoplasia (CIN) 2 or 3, 70 with CIN 1, and 515 control women. We used logistic regression analysis to estimate associations between HIV-1 and HIV-2 infection and the risk of cervical neoplasia. We found large increases in the risk of ICC and CIN 2-3, but not of CIN 1, associated with the presence of either HIV-1 or HIV-2 infection (odds ratios of 6.5 and 10.4 for ICC and CIN 2-3). Our analysis thus shows increases in the risk of both advanced and early cervical pathology associated with HIV infection in an African population.
