Functional Imaging of Tumor and Normal Tissue
Dynamic contrast-enhanced (DCE) - magnetic resonance imaging (MRI), diffusion-weighted (DW)-MRI, and fludeoxyglucose - positron emission tomography - computed tomography (FDG-PET-CT) are three modalities that generate non-invasive, functional images of tumors and normal tissues based on physiologic properties including perfusion, vascular permeability and glucose metabolism. Demonstrating that these parameters are associated with clinical outcome, either efficacy or toxicity, could enhance the ability to select patients for different treatment strategies and improve the therapeutic ratio.
Patients will undergo functional imaging studies, DCE-MRI pre-treatment (twice) and after 1 week of Radiation Therapy (RT) and PET scans - pre-treatment and after 1 week of RT. Parotid gland saliva production will also be measured at baseline and at 3, 6, and 12 months of follow-up.

Head And Neck Neoplasms
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
We have developed a prototype PET insert device that can be integrated into a clinical PET/computed tomography (CT) scanner to improve its image resolution to approximately 2.5 mm in all 3...
Through this study, we hope to learn more about the mechanisms, which may contribute to development and progression of head and neck cancer. The long-term goal of this study will be to de...
The primary objective of this study is to describe, in detail, patterns of care for head and neck carcinoma patient
The purpose of this study is to investigate the clinical value of serial quantitative [F-18] FLT as a PET imaging tool in head and neck cancer patients clinically scheduled with radiation...
Patients with head and neck cancer frequently develop synchronous or metachronous esophageal malignancies. Previous studies have demonstrated the efficacy of endoscopic screening for esoph...
Scientific innovation has enabled whole exome capture and massively parallel sequencing of cancer genomes. In head and neck cancer, next-generation sequencing has granted us further understanding of t...
BACKGROUND: The purpose of this study was to evaluate combined autofluorescence (AF) and narrow band imaging (NBI) for detection of mucosal lesions additional to known primary head and neck cancers an...
BACKGROUND: Head and neck cancer is a common second cancer in patients with a history of hematological malignancies. The purpose of this study was present the clinical characteristics and treatment ou...
BACKGROUND: Estimation of attributable fractions for tobacco and alcohol, and investigation of the association between body mass index (BMI) and head and neck cancer risk have largely been in case-con...
