BACKGROUND : Cystic lymph node metastases have been associated with tonsil cancer. A subset of oropharyngeal cancers contain human papillomavirus (HPV) DNA. The clinical and virologic associations of cystic nodal metastasis in head and neck cancer (HNSCC) were investigated. METHODS : A retrospective review of patients undergoing neck dissection between(More)
CONTEXT Medullary thyroid cancer (MTC) is a rare thyroid cancer that can occur sporadically or as part of a hereditary syndrome. OBJECTIVE To explore the genetic origin of MTC, we sequenced the protein coding exons of approximately 21,000 genes in 17 sporadic MTCs. PATIENTS AND DESIGN We sequenced the exomes of 17 sporadic MTCs and validated the(More)
In stargazer mutant mice, a mutation in the gene encoding stargazin results in absence epilepsy, cerebellar ataxia, and a characteristic abnormal motor syndrome. The main goal of the current studies was to characterize the nature and source of the abnormal motor behavior. Because the stargazer motor syndrome resembles that of other rodents with vestibular(More)
Head and Neck Squamous Cell Carcinoma (HNSCC) is the fifth most common cancer, annually affecting over half a million people worldwide. Presently, there are no accepted biomarkers for clinical detection and surveillance of HNSCC. In this work, a comprehensive genome-wide analysis of epigenetic alterations in primary HNSCC tumors was employed in conjunction(More)
Silencing of tumor suppressor genes plays a vital role in head and neck carcinogenesis. In this study, we aimed to evaluate to the utility of aberrant promoter hypermethylation for detection in a panel of 10 genes (KIF1A, EDNRB, CDH4, TERT, CD44, NISCH, PAK3, VGF, MAL and FKBP4) in head and neck squamous cell carcinoma (HNSCC) via a candidate gene approach.(More)
PURPOSE Hypermethylation of tumor suppressor gene promoters has been found in head and neck squamous carcinoma (HNSCC) and other solid tumors. We evaluated these alterations in pretreatment salivary rinses from HNSCC patients by using real-time quantitative methylation-specific PCR (Q-MSP). EXPERIMENTAL DESIGN Pretreatment saliva DNA samples from HNSCC(More)
OBJECTIVE To examine the role of MAGEA2 in the tumorigenesis of head and neck squamous cell carcinoma (HNSCC). DESIGN Primary tissue microarray data and quantitative reverse transcription-polymerase chain reaction (RT-PCR) showed that MAGEA2 is differentially overexpressed in HNSCC. Functional analyses were then performed using MAGEA2 transfections and(More)
BACKGROUND Cancer/testis antigens (CTAs) were first discovered as immunogenic targets normally expressed in germline cells, but differentially expressed in a variety of human cancers. In this study, we used an integrative epigenetic screening approach to identify coordinately expressed genes in human non-small cell lung cancer (NSCLC) whose transcription is(More)
PURPOSE To validate a panel of methylation-based salivary rinse biomarkers (P16, CCNA1, DCC, TIMP3, MGMT, DAPK, and MINT31) previously shown to be independently associated with poor overall survival and local recurrence in a larger, separate cohort of patients with head and neck squamous cell carcinoma (HNSCC). EXPERIMENTAL DESIGN One hundred ninety-seven(More)
INTRODUCTION Lymphoscintigraphy in melanoma provides important information on the dynamic drainage of the primary tumour and the location of the sentinel lymph node (SLN). Unfortunately these images lack anatomical detail. Single positron emission computed tomography/computed tomography (SPECT/CT) provides extremely detailed information on the location of(More)
