background &objective: breast cancer is the most common female malignancy. detection of dna of human papillomaviruses (hpvs) in breast carcinomas suggests that the virus may play a role in the pathogenesis of this disease. the aim of this study was to evaluate the frequency of hpvs genotypes 6, 11, 16, 18 and 31 in paraffin-embedded tissue samples of invasive breast carcinomas. methods: thr...
The present study was undertaken to evaluate the prevalence of HPV in formalin-fixed, paraffin-embedded cervical carcinoma tissues using PCR followed by non-radioactive Southern hybridization with type-specific oligonucleotides for HPV 16 and 18. In addition, the tissue sections were immunohistochemically screened with two monoclonal antibodies, for expression of HPV 16 L1 and HPV 18 E6 protein...
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...
We examined United States Surveillance, Epidemiology, and End Results incidence data and conducted a population-based case-control study to examine the role of human papillomavirus (HPV) and oral contraceptive (OC) use in the etiology of adenocarcinoma in situ of the cervix (ACIS). One hundred and fifty women diagnosed with ACIS and 651 randomly selected control women completed in-person interv...
Epidemiological evidence is accumulating that sexual history may be associated with prostate cancer, and some studies have suggested a relation between human papilloma virus (HPV) infections and prostate cancer. We measured the presence of antibodies to the major oncogenic HPV types 16, 18, and 33 among 238 subjects with untreated prostate cancer and 210 population-based control subjects. Odds ...
Our understanding of humoral response to human papillomavirus (HPV) infection has been mainly derived from studies in women. The role of serum antibodies in the natural history of HPV in men has yet to be investigated. Data from 285 male participants of a natural history study were used to determine the epidemiologic factors associated with HPV 16/18 seropositivity and explore the role of HPV 1...
OBJECTIVE This study evaluates the effect of the specific human papillomavirus (HPV) genotype as a prognostic factor in stage I-IIA cervical cancer patients following primary surgical treatment. METHODS The medical records of 116 cervical cancer patients treated with primary surgical treatment were reviewed. The HPV genotypes were categorized into following groups: negative and unclassified, ...
This phase II/III, double-blind, randomized trial assessed the efficacy, immunogenicity and safety of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine in young Chinese women (ClinicalTrials.gov registration NCT00779766). Women aged 18-25 years from Jiangsu province were randomized (1:1) to receive HPV vaccine (n = 3,026) or Al(OH)3 control (n = 3,025) at months 0, 1 and 6. The prima...
The aim of this study was to determine human papillomavirus (HPV) type distribution in women with and without cervical neoplasia from Asia and to estimate the potential future impact of an HPV 16/18 prophylactic vaccine in this region. A meta-analysis was conducted including 79 studies using polymerase chain reaction to detect HPV types. A total of 5954, 1653, 958, and 16,803 women with invasiv...
BACKGROUND Not all women infected with HPV-16/18 have detectable levels of HPV-16/18 antibodies, those who seroconvert develop low antibody levels, and seroconversion occurs typically several months post-infection. We evaluated determinants of seropositivity among 646 women infected with HPV-16 and/or HPV-18. METHODS Data are from the enrollment visit of the NCI-sponsored Costa Rica HPV Vacci...
