HIV and cancer of the cervix

Abstract

Cancer of the cervix is the second most common cause of cancer-related death in women worldwide, and in some low resource countries accounts for the highest cancer mortality in women. The highest burden of the HIV/AIDS epidemic is currently in sub-Saharan Africa, where more than half of the people infected are women who have no access to cervical cancer screening. The association between HIV and invasive cervical cancer is complex, with several studies now clearly demonstrating an increased risk of pre-invasive cervical lesions among HIV-infected women. However, there have not been significantly higher incidence rates of invasive cervical cancer associated with the HIV epidemic. The highest numbers of HIV-infected women are in poorly-resourced countries, where the natural progression of HIV disease in the absence of highly active antiretroviral treatment sometimes results in deaths from opportunistic infections before the onset of invasive cervical cancer. This chapter will discuss the association of HIV and cervical intraepithelial neoplasia, the treatment of pre-invasive lesions, and invasive cervical cancer in HIV-infected women. The role of screening and the impact of antiretroviral treatment on the progression of pre-invasive and invasive cancer will also be discussed.
