BACKGROUND Data on the prevalence of cervical HPV genotypes in Australia by age and by grade of cytological abnormality are sparse. OBJECTIVE Measure prevalence of HPV genotypes among 2620 Australian women by age and cytology status. STUDY DESIGN Women presenting for routine Pap smear screening were recruited from diverse regions, including a significant sample of Indigenous women. DNA extr...

BACKGROUND Little is known about the association between oral and anogenital human papillomavirus (HPV) infections. METHODS Oral and anal samples from 66 men who have sex with men with a history of HPV-related anogenital squamous intraepithelial lesions were analyzed using polymerase chain reaction (PCR), and typed for 38 HPV types. RESULTS Prevalence of oral HPV infection was 30%, versus 8...

OBJECTIVES To describe prevalence and estimated attribution of human papillomavirus (HPV) types in U.S. cervical, vaginal, and vulvar precancers and cancers. METHODS U.S. studies reporting HPV typing for cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), and vaginal intraepithelial neoplasia (VaIN) and/or invasive cancers of those sites were gathered from the Pu...

Clinical, subclinical, and latent human papillomavirus (HPV) infections are distinguished from HPV-associated neoplasia. Besides HPV additional cofactors are necessary to transform HPV infected tissue to intraepithelial or invasive neoplasia. Risk factors for the presence of HPV are high number of sexual partners, early cohabitarche, young age at first delivery, suppression and alteration of im...

BACKGROUND Human papillomaviruses (HPVs) are sexually transmitted human carcinogens that may play a role in the oncogenesis of penile cancer. OBJECTIVES To investigate the role of HPV infection and expression of the tumour suppressor protein p16INK4A in the pathogenesis of penile cancer. METHODS By means of polymerase chain reaction amplification and reverse hybridization line probe assay t...

Objective: Human papillomavirus (HPV) is the primary cause of cervical cancer. The purpose of this study was to investigate the prevalence and type distribution of HPV DNA positive in women undergoing routine physical examination. Methods: 2,452 women were enrolled between March and November 2013. Participants were tested for 23 HPV types using polymerase chain reaction (PCR) and reverse dot bl...

The role of Human Papillomavirus (HPV) in colorectal carcinogenesis remains elusive. Based on the high incidence of HPV-associated malignancies among Puerto Rican Hispanics, this study aimed to assess the prevalence of HPV infection and viral integration in colorectal tissues in order to evaluate its putative role in colorectal cancer (CRC). In this case-control study, the prevalence of HPV inf...

BACKGROUND In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana. METHODS Before the study, the study team communicated in the remote villages on the importance of screening. All women from the targ...

BACKGROUND It is well established that the prevalence of human papillomavirus (HPV) infection is increased among human immunodeficiency virus (HIV)-positive individuals, but the temporal relationships between these infections are unclear. METHODS During a South African cervical cancer screening trial, 5595 women 35-65 years of age were followed up for 36 months; 577 women were HIV positive at...

BACKGROUND There is conclusive evidence that human papillomavirus (HPV) infections of the cervix are a necessary cause of cervical cancer. In Italy there are consistent data of HPV prevalence in women aged 25 - 64 years, but there is limited data for younger women. The objective of this on-going 3-year prospective cohort study is to investigate the prevalence, acquisition, clearance and persist...
