Unique human papillomavirus-type distribution in South African women with invasive cervical cancer and the effect of human immunodeficiency virus infection.

Objectives Cervical cancer is the most common cause of cancer-related deaths among South African women. Viral types associated with cervical cancer may differ not only between countries and regions, but possibly also between human immunodeficiency virus (HIV)–infected and noninfected women. Methods In a population with high HIV prevalence, human papillomavirus (HPV)–type infections detected with DNA analyses were reported in a cohort of 299 women diagnosed with invasive cervical cancer. Results One hundred fifty-four women tested HIV negative, 77 tested HIV positive, and HIV status was unknown for 68 women. The mean age for HIV-positive women was 41.3 years, and that for HIV-negative women was 55.8 years (P Conclusions A high number of women in South Africa with cervical cancer are HIV positive. Without viral cross-protection, HPV vaccines should prevent around 65% of cervical cancers in this population. Human papillomavirus type 45 infection is significantly linked to HIV and important for future vaccine developments.
