Here we evaluated the prevalence of Human Papillomavirus (HPV) in two groups of Chilean women. The first group consisted of 3,235 women aged 18-64 years attended in six primary care centres of Santiago. The second group consisted of 456 women 18-85 aged who consulted the Gynaecology Department of the Reference Hospital of Santiago. Samples were collected from October 2012 to February 2016. Cervical swabs were analyzed both HPV genotyping by PCR and Reverse Line Blot, and cervical cytology by Pap testing. Results showed a prevalence of 12...

BACKGROUND: Human papillomavirus (HPV) is the carcinogen of almost all invasive cervical cancer and a major cause of oral and other anogenital malignancies. HPV genotyping by dideoxy (Sanger) sequencing is currently the reference method of choice for clinical diagnostics. However, for samples with multiple HPV infections, genotype identification is singular and occasionally imprecise or indeterminable due to overlapping chromatograms. Our aim was to explore and compare HPV metagenomes in abnormal cervical cytology by deep sequencing for correlation with disease states...

Despite a reduction in smoking and alcohol consumption, the incidence of oropharyngeal squamous cell carcinoma (OPSCC) is rising. This is attributed to human papilloma virus (HPV) infection and screening for HPV is now recommended in all cases of OPSCC. Despite a variety of clinically available tests and new non-invasive test strategies there is no consensus on which technique is best. This review reports on current techniques for HPV detection in OPSCC and the clinical applicability of emerging techniques...

Testing negative for human papillomavirus (HPV) predicts long-term reassurance against invasive cervical cancer (ICC). To provide realistic estimates of effectiveness for new screening programs, we studied ICC risk after a 7-year repeated multimethod screening effort. In 1993-1994, 10,049 women aged 18-97 years were enrolled into a population-based cohort study of cervical HPV in Guanacaste, Costa Rica. Women were screened at different intervals according to enrollment results. Each visit (mean 3.2, 90% attendance) included split-sample conventional, automated, and liquid-based cytology, visual inspection, cervicography, and PCR-based HPV testing...

BACKGROUND: Human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (SCC) has a better outcome than most head neck squamous cell carcinomas (HNSCCs) and an HPV-positive lymph node metastasis likely has an HPV-positive oropharyngeal SCC origin. Determining HPV-status in cervical lymph nodes by fine-needle aspiration cytology (FNAC) may be useful for diagnosis. METHODS: FNACs from 66 patients with neck masses were prospectively examined for HPV DNA and HPV16 mRNA by a polymerase chain reaction (PCR)-based assay, and the data correlated to diagnosis and HPV-status obtained from histopathological specimens...

Cervical cancer (CC) is one of the most common cancers among women worldwide. The relation of the human papillomavirus (HPV) with CC and its precursor lesions was first suspected for over 40 years. The indoleamine 2,3 dioxygenase (IDO) is an immune modulator enzyme responsible for the immune system tissue protection mechanism, which may be the key to the tumoural persistence. HPV oncoprotein E7 promotes the increase in cyclin-dependent kinase inhibitor p16 (CDKN2A/p16). The isolated and combined analysis of CDKN2A/p16 mRNA to CC diagnosis was done with promising results...
