The use of a single broad-spectrum human papillomavirus (HPV) DNA-based PCR test may fail to detect lower concentrations of HPV DNA due to competition between different genotypes in mixed infections. To improve HPV detection by PCR, broad-spectrum and type-specific (TS) PCRs were combined, with a focus on HPV-16 and HPV-18. Cervical and cervicovaginal cell samples were obtained from 1,113 healt...
BACKGROUND Oropharyngeal squamous cell carcinomas (OSCCs) are associated with high-grade human papillomavirus (HPV) infection in 20% to 30% of cases. HPV-16 DNA has been detected in cervical lymph node metastases of HPV-16(+) OSCC. However, the meaning of HPV-16 DNA detection in lymph nodes remains controversial. Does the presence of HPV-16 DNA in lymph nodes correlate with their metastatic inv...
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...
BACKGROUND The control arm of PATRICIA (PApilloma TRIal against Cancer In young Adults, NCT00122681) was used to investigate the risk of progression from cervical HPV infection to cervical intraepithelial neoplasia (CIN) or clearance of infection, and associated determinants. METHODS AND FINDINGS Women aged 15-25 years were enrolled. A 6-month persistent HPV infection (6MPI) was defined as de...
Human papillomavirus (HPV) L1 gene methylation deeply involved in the progression and heterogeneity of cervical cell epithelial lesions. The DNA ploidy also represented the early lesions of cervical cell, and it was associated with different HPV infection status in different ethnic women. So, the research was to explore whether it was possible that HPV L1 gene methylation and HPV infection stat...
Women remain at risk of human papillomavirus (HPV) infection for most of their lives. The duration of protection against HPV-16/18 from prophylactic vaccination remains unknown. We investigated the 10-year immune response and long-term safety profile of the HPV-16/18 AS04-adjuvanted vaccine (AS04-HPV-16/18 vaccine) in females aged between 15 and 55 years at first vaccination. Females who receiv...
Numerous studies have evaluated human papillomavirus (HPV) DNA load in women, especially HPV-16 viral load, and its role in cervical carcinogenicity. Few studies have examined HPV viral load in men, none among asymptomatic men. The aim of the current study is to quantify HPV-16 viral load in male anogenital specimens and to explore its correlates with anatomic sites. Two-hundred and ninety-four...
Background. A significant number of non-small-cell lung cancers (NSCLC) have human papillomavirus (HPV) DNA integrated in their genome. This study sought to further establish HPV's possible etiologic link to NSCLC by evaluating an immune response to HPV's oncogene, E7, in patients with NSCLC. Patients and Methods. Antibodies (IgG) in serum against E7 for HPV 16 and 18 in 100 patients with NSCLC...
Our earlier study demonstrated high prevalence of multiple human papillomavirus (HPV) infection in patients with invasive uterine cervical cancer, including squamous cell carcinoma (SCC). HPV 16 is the most predominant genotype related to SCC of the uterine cervix. The aim of this study was to reveal the biological significance of multiple HPV infection concerning the tumor progression of invas...
