BACKGROUND: Human papillomavirus (HPV), has been recognized as an vital preliminary event in the oncogenesis of cervical cancer. But the prognostic value is not well defined, because of past studies showing conflicting results. So we conducted this meta-analysis to evaluate whether HPV DNA status was associated with prognosis in cervical cancer. MATERIALS AND METHODS: A total of 17 previously published eligible studies including 2,838 cases were identified and included in this meta-analysis...

BACKGROUND: The majority of anal cancers (84-95%) are driven by infection with human papillomavirus (HPV). HPV-positive tumours show significantly better responses to chemo-radiotherapy when compared with HPV-negative tumours. HPV infection is linked to alterations in DNA damage response proteins, including MRE11. MRE11 is a potential predictive biomarker for response to radiotherapy in muscle-invasive bladder cancer and may hold predictive power in other cancers. METHODS: Using a previously reported cohort, we evaluated the levels of MRE11 in anal cancer and assessed its predictive value in this disease...

The role of different types of human papillomavirus (HPV) in the development of oral and oropharyngeal papillomas remains unclear. High-risk HPV (HR-HPV) was shown to be involved in the pathogenesis of significant proportion of squamous cell carcinomas of the oropharynx. In this study, we hypothesized that in some oropharyngeal papillomas, low-risk HPV (LR-HPV) and HR-HPV infection could co-exist, similar to what is observed in genital warts, and thus contribute to the elevated risk of malignancy. To test this hypothesis, we used real-time PCR to assess the presence of HPV DNA of 16 types (2 LR-HPV and 14 HR-HPV), in 75 formalin-fixed and paraffin-embedded histopathological samples of oral and oropharyngeal papillomas and in 57 squamous cell carcinomas from the same regions...

BACKGROUND: It is unclear why human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) has improved clinical behavior compared to HPV-negative HNSCC. We sought to better characterize the immune microenvironment of tongue cancers by examining the CD3 and CD8 TIL pattern in HPV-positive and -negative tumors. METHODS: Histologic sections from 40 oral tongue and oropharyngeal cases were analyzed (n= 21 HPV DNA-positive, n= 19 HPV DNA-negative)...

Human papillomavirus (HPV) infection distinctly alters methylation patterns in HPV-associated cancer. We have recently reported that HPV E7-dependent promoter hypermethylation leads to downregulation of the chemokine CXCL14 and suppression of antitumor immune responses. To investigate the extent of gene expression dysregulated by HPV E7-induced DNA methylation, we analyzed parallel global gene expression and DNA methylation using normal immortalized keratinocyte lines, NIKS, NIKS-16, NIKS-18, and NIKS-16∆E7...

BACKGROUND: New cases of oropharyngeal squamous cell carcinoma (OPSCC) are routinely tested for HPV. HPV in saliva can be detected with PCR, but its clinical applicability in the context of OPSCC remains unknown. METHODS: Forty-six consecutive patients diagnosed with OPSCC had pre-treatment saliva specimens collected. PCR for HPV on saliva was compared to p16 IHC and HPV DNA in-situ hybridisation (ISH) on surgical biopsies. RESULTS: The sensitivity and specificity of saliva testing when compared to the reference test of p16 IHC and HPV DNA ISH was 72...

Positively-charged nylon membrane (NM) is a general solid-phase support for nucleic acid detection due to its convenient immobilization of nucleic acid materials by direct electrostatic adherence and simple UV crosslinking. Rolling circle amplification (RCA) is a widely used isothermal DNA amplification technique for nucleic acid detection. Near-infrared fluorescence (NIRF) is a new fluorescence technique with high sensitivity due to low background. This study developed a simple method for detecting nucleic acid molecules by combining the advantages of NM, RCA and NIRF, named NIRF-based solid phase RCA on nylon membrane (NM-NIRF-sRCA)...
