Association of HPV35 with cervical carcinogenesis among women of African ancestry: Evidence of viral‐host interaction with implications for disease intervention

HPV35 has been found in only ∼2% of invasive cervical cancers (ICC) worldwide but up to 10% in Sub‐Saharan Africa, warranting further investigation and consideration of impact on preventive strategies. We studied HPV35 and ethnicity, in relation to the known steps in cervical carcinogenesis, using multiple large epidemiologic studies in the U.S. and internationally. Combining five U.S. studies, we measured HPV35 positivity and, in Northern California, observed HPV35 type‐specific population prevalence and estimated 5‐year risk of developing precancer when HPV35‐positive. HPV35 genetic variation was examined for differences in carcinogenicity in 1053 HPV35+ cervical specimens from a U.S. cohort and an international collection. African‐American women had more HPV35 (12.1% vs 5.1%, P
