Human papillomavirus prevalence and type distribution in invasive cervical cancer in sub-Saharan Africa.
In sub-Saharan Africa, invasive cervical cancer (ICC) incidence and mortality are among the highest in the world. This cross-sectional epidemiological study assessed human papillomavirus (HPV) prevalence and type distribution in women with ICC in Ghana, Nigeria, and South Africa. Cervical biopsy specimens were obtained from women aged ≥ 21 years with lesions clinically suggestive of ICC. ⋯ In ICC cases with single HPV infection (447/515 [86.8%]), the most commonly detected HPV types were HPV16 (51.2%), HPV18 (17.2%), HPV35 (8.7%), HPV45 (7.4%), HPV33 (4.0%) and HPV52 (2.2%). The prevalence of single and multiple HPV infections seemed higher among HIV-positive women and HPV type distribution appeared to differ according to tumor type and HIV status. In conclusion, HPV16, 18, 45 and 35 were the most common HPV types in sub-Saharan African women with ICC and HPV infections were more common in HIV-positive women.
