OBJECTIVE Multiple human papillomavirus (HPV) infection of the uterine cervix has been suggested as a risk factor for persistent HPV infection, resulting in the development of invasive cervical cancer. The aim of this study was to reveal the actual state of multiple HPV infection in Japanese patients with invasive cervical cancer. METHODS Sixty fresh-frozen invasive cervical cancer tissues we...

BACKGROUND Little is known regarding the human papillomaviruses (HPV) genotypes prevalent in women in South Africa, a country with a high incidence of cervical cancer. OBJECTIVE To determine the prevalence and HPV genotypes in women with squamous abnormalities and normal cervixes participating in a community-based microbicide study. STUDY DESIGN A total of 159 cervical specimens, including ...

Human papillomavirus (HPV) can induce a wide spectrum of squamous intraepithelial lesions (SIL) of varying severity. The aim of the present study was to establish the frequency of HPV infection and identify the genotypes circulating in women from Córdoba, Argentina, in relation to age and cytology. A total of 186 women, between 18 and 65 years old, with antecedents of SIL, underwent a pelvic ex...

Aim: Head and Neck Squamous Cell Carcinoma (HNSCC) is a global health problem whose incidence varies by geographic region race according to risk factors. Human papillomavirus (HPV) infection significant factor for HNSCC. HPV-16 HPV-18 are two forms of HPV that carcinogenic. HNSCCs positive have better prognosis rather than negative. The purpose this research was characterize HPV-16, -18 variati...

A comparison of two PCR-based human papillomavirus (HPV) DNA detection and genotyping systems (PGMY LBA and SPF(10) LiPA) was conducted in two laboratories. Both systems are based on broad-spectrum PCR for the detection of HPV DNA, followed by reverse hybridization with type-specific probes. A total of 400 selected cervical scrape specimens in PreservCyt solution (55% normal cytology, 18% atypi...

BACKGROUND The New Mexico HPV Pap Registry was established to measure the impact of cervical cancer prevention strategies in the United States. Before widespread human papillomavirus (HPV) vaccine implementation, we established the baseline prevalence for a broad spectrum of HPV genotypes across the continuum of cervical intraepithelial neoplasia (CIN) and cancer. METHODS A population-based s...

BACKGROUND We studied anal specimens to determine the distribution of human papillomavirus (HPV) genotypes and co-infection occurrence. This information will contribute to the knowledge of HPV genotype distributions and provide an estimate of the prevalence of different oncogenic HPV genotypes found in patients in Madrid (Spain). METHODS We studied a total of 82 anal biopsies from the Hospita...

BACKGROUND Cervical cancer prevention using cervical cytology is insufficiently sensitive, a significant proportion of HPV-infected women having normal cytology. The objective of the present study was to try to identify factors associated with abnormal cytology in HPV-infected women living in remote areas of French Guiana. METHODS A study was conducted in women aged 20-65 years having HPV inf...

Multiple human papillomavirus (HPV) genotypes often coexist within the cervical epithelia and are frequently detected together in various grades of the cervical neoplasia. To date, only a few reports exist on multiple HPV infections of HPV in Xinjiang Uygur Autonomous Region (XUAR). In the present study, we investigated the prevalence of High-Risk HPV (HR-HPV) genotypes and multiple infections....

A group of 208 human immunodeficiency virus (HIV)-infected women in Brazil were studied for the presence of human papillomavirus with the general SPF(10) PCR primer set. Virtually all (98%) women were found positive for human papillomavirus (HPV) DNA. Genotyping by the reverse hybridization line probe assay (HPV-LiPA) revealed a high prevalence of multiple genotypes (78.9% of the cases), with a...
