Purpose: To investigate the frequency, localization, and survival of second primary tumors (SPT) oropharyngeal squamous cell carcinoma (OPSCC) depending on human papillomavirus (HPV) status. Methods: We performed a retrospective chart analysis 107 OPSCC patients treated at Zurich University Hospital from 2001 to 2010. Rate localization SPT after an index were stratified according smoking HPV in...

Introduction. Human papillomavirus 13 (HPV-13) belonging to Alphapapillomavirus-10 species, is an oral mucosotropic virus phylogenetically related others human (6, 11, 44, 55 and 74). It causes Multifocal Epithelial Hyperplasia, uncommon benign disease reported mainly amongst ethnic groups from America. Objective. To describe the genetic variability of HPV-13 L1 gene. Material Methods. A retros...

Objective: Cervical cancer is caused by human papilloma virus (HPV) infection, and cervical intraepithelial neoplasia (CIN) a precancerous lesion. Common treatments for CIN are conization laser vaporization. HPV testing useful predicting residual or recurrent disease after surgical treatment. We performed high-risk (HR-HPV) genotyping postoperatively to examine the positivity rate determine whe...

Human papillomavirus (HPV) infection has been implicated as a causative of cervical cancer. In the present study, a total of 578 samples from females attending the gynecological outpatient clinic in Henan province, China, were collected and the HPV genotypes were detected by gene chip and flow-through hybridization. Overall, 44.5% (257/578) females were found to be HPV DNA positive, and the hig...

results hpv-16 e6 and e7 proteins reduced e-cadherin expression 3.7 and 2.2 times when compared with control cells (p = 0.0221 and p = 0.0461, respectively). this reduction was greater in hpv-16 e6-expressing cells than in hpv-16 e7-expressing cells. although hpv-16 e6 and e7 increased dna methyltransferase 1 expression 2.6 and 3.4 times, respectively (p = 0.0133 and p = 0.0113) when compared w...

Sinonasal cancers represent a highly heterogeneous group of head and neck cancers, for which etiological prognostic significance high-risk human papillomavirus (HPV) infections has not yet been conclusively established. We investigated the presence transcriptionally-active HPV in series 34 sinonasal squamous cell cancer (SNSCC) cases evaluated effect on overall survival. In addition, we perform...

Zusammenfassung Ursprünglich als Impfung gegen Gebärmutterhalskrebs geplant, haben HPV(humane Papillomviren)-Impfungen unsere Erwartungen weit übertroffen. Sie das Potenzial, bei Frauen und Männern mindestens 6 Karzinomtypen, deren Vorstufen sowie Genitalwarzen zu verhindern sogar eliminieren. Nach 14 Jahren Anwendung wissen wir, dass HPV-Impfprogramme hocheffektiv sind, frühe eine gute Durchim...
