## Abstract Freshβfrozen biopsies were obtained from 61 patients at diagnosis of squamous cell carcinoma of the head and neck (HNSCC) for study of the prevalence and physical status of human papillomavirus (HPV) DNA. The frequency of HPV DNA and genotypes were determined by SPF10 PCR screening with

Abstract
Background.
Human papillomavirus (HPV) is a basic risk factor for head and neck squamous cell carcinoma (HNSCC). Little knowledge exists about the impact of HPV on clinical diagnostic and therapy of patients with HNSCC.
Methods.
We evaluated the evidence of HPV16 in 131 retrospectively collected HNSCC and associated cervical lymph node metastases by HPV16 realβtime polymerase chain reaction (PCR) and __p__16 immunohistochemistry and its impact on clinicopathological characteristics.
Results.
HPV16βDNA and __p__16 overexpression were present in 27% of HNSCCs. All cervical lymph node metastases of HPV16βpositive HNSCC showed HPV16βDNA. HPV16 was strongly associated with tumors arising from the oropharyngeal site (p < .000001), favorable outcome after standard therapy in univariate (p = .001) and multivariate (p = .0004) analysis, and cervical lymph node metastases before primary detection.
Conclusion.
HPV16βdiagnostic in cervical lymph node metastases can predict the site of tumor origin in case of carcinoma of unknown primary (CUP) and favorable outcome and should, therefore, be included in routine diagnostic workup. Β© 2010 Wiley Periodicals, Inc. Head Neck, 2011

## Abstract ## Background. We investigated the incremental diagnostic value of short tau inversion recovery (STIR) MRI to detect cervical nodal metastases in head and neck squamous cell carcinoma. ## Methods. Thirtyβsix patients with cervical nodal metastases underwent MRI preceding neck dissect
## Abstract ## Background. Because of the impact of nodal status on treatment and survival in squamous cell carcinoma of the head and neck, accurate staging of cervical lymph nodes is critical. This article explores the value of molecular analyses in the detection of cervical lymph node metastasis
Background. Prognosis of head and neck squamous cell carcinoma (HNSCC) is strongly associated with cervical lymph node metastasis. Cathepsin-D is a lysosomal protease expressed in all cells. Its role in extracellular matrix degradation is postulated to promote tumor invasion and metastasis. Increase
## Abstract An etiologic role for human papillomavirus (HPV) infections in either head and neck (HNC) or esophageal carcinogenesis remains debatable. Patients with head and neck cancer are at high risk for developing a second esophageal squamous cell cancer (ESCC). The aim of our study was to deter
## We have previously reported that immune anti-tumor effector cells, both cytotoxic T lymphocytes (CTLs ) and IL-2-activated natural killer (A-NK) cells, are effective at eliminating human head-and-neck cancer (HNC) targets in vitro and in vivo in xenograft models. In this study, these 2 types of
