Active clinical trials for "Head and Neck Neoplasms"

RATIONALE: Diagnostic procedures, such as analysis of tumor tissue and lymph nodes that have been surgically removed, may improve the treatment of patients with cancers of the head and neck. PURPOSE: Diagnostic trial to determine if analyzing tumor tissue and lymph nodes surgically removed from patients with cancers of the head and neck can predict recurrence of the cancer.

The purpose of this study is to evaluate this new technology available at the University of Wisconsin Carbone Cancer Center in the setting of head and neck cancer radiation treatment planning. This study will also provide preliminary data critical to the development of multi-parametric, multi-modality quantitative imaging biomarkers and data analysis models for prediction of outcome in both tumors and normal tissue, which are essential for patient-specific adaptive therapy. All participants will undergo a diagnostic PET/CT and a Radiation Treatment Planning CT per SOC procedures. In addition, all participants will undergo an additional imaging set consisting of a PET/MRI. It is anticipated that most patients will undergo the PET/MRI on the same day as their PET/CT negating the need for a second injection of the FDG radioisotope used for SOC PET imaging. All patients will receive gadolinium contrast per SOC dosing guidelines for the MRI portion of the PET/MRI. Both SOC MMRI pulse sequences and investigational sequences will be utilized in this study.

The goal of this data review research study is to create a registry database using information (data) collected from patients who have had Endoscopic Head and Neck Surgery (eHNS). Researchers want to use the registry database to learn more about short-term and long-term outcomes for patients who have eHNS. 1.1 Primary Objective: To develop a registry database of patients who have had eHNS. 1.2 Secondary Objective: To evaluate short-term oncologic parameters and functional outcomes, operative for patients undergoing eHNS performed at M.D. Anderson Cancer Center (MDACC). 1.3 Tertiary Objective: To collect data on long-term oncologic outcomes including local and distant failure and survival following eHNS.

This study is a prospective collection of data utilizing the Imaging Beta Probe (IBP) in patients with positron emission tomography (PET) positive disease. A pilot clinical study involving 5 patients will be conducted using the IBP. The sterilized IBP will be used intraoperatively in surgical wounds for localization of tumor sites and detecting completeness of excision vs. positive margins. The outcome of each of these studies will be documented and used to demonstrate clinical benefits of the new probe. The investigators will correlate the images from the probe of the Fludeoxyglucose (18FDG) positive tissue, both in-vivo and ex-vivo after dissection, with the previously performed PET scan and with the routine pathology results obtained on the surgical specimens.The experimental imaging modality studied in this protocol will be compared to clinically utilized modalities of ultrasound and PET/ CT. Localization between imaging modalities will be compared with respect to: detection and side of localization.

This study will look at the genetic profile of cells taken from the oral cavity of healthy college students who smoke and who do not smoke cigarettes. This will be done using a small brush similar to that used in Pap tests for cervical cancer detection. Our aim is to determine if smoking causes early genetic changes in the DNA of these cells such as have been seen in the cells of cancerous tumors of the head and neck area and nearby healthy tissues. This will be correlated with data from subject questionnaires to assess tobacco use, and other behavior and demographic information.

The purpose of this study is to assess a relatively new PET (Positron emission tomography) radiotracer called FACBC in the assessment of head and neck cancer. FDG (Flourine Deoxyglucose) is currently used for PET imaging, but has limitations in head and neck cancer. These limitations include problems with specificity, high background uptake from normal structures, difficulty delineating intracranial invasion, and the need to wait several weeks after chemotherapy and radiation before imaging. As an amino acid radiotracer, rather than a glucose radiotracer, FACBC overcomes some of these limitations. FACBC does not yet have FDA (Food and Drug Administration) approval, but does show promise in initial work in patients with prostate cancer and brain tumors. Dosimetry work on FACBC has been performed at Emory. Our study is a pilot study looking at 10 patients with a new diagnosis of biopsy proven squamous cell carcinoma of the oral cavity who will be able to go on to definitive surgical resection (ie, surgery without preceding chemotherapy or radiation). Patients must have pre-surgical imaging, either with a contrast enhanced CT, FDG PET, or MRI. Patients who consent to participate will receive one FACBC PET/CT of the neck, which will require a low dose "transmission" CT of the neck, an intravenous injection of the radiotracer, and imaging of the neck that will last up to 1 hour. Patients will have to lie still during the imaging time. Total participation time including set up should be less than 90 minutes. Imaging results will be analyzed and compared with conventional imaging as well as the surgical pathology results

The purpose of this study is to improve the quality of care provided for head and neck cancer patients. By better understanding the end of life experiences of dying patients and their families, the investigators hope to better anticipate and improve upon the experiences of future patients and their families.

Hypoxia and tumor cell proliferation are important mechanisms contributing to resistance to radiotherapy in human head and neck tumor cells. Currently, assessment of these two tumor characteristics is performed in biopsies using immunohistochemical staining and subsequent analysis. A promising non-invasive method of characterizing a tumor is the use of positron-emission tomography (PET). Specific tracers can be used to detect hypoxia and proliferative activity. 18F-misonidazole is a tracer for hypoxia and 18F-thymidine is a tracer for proliferation. Patients suffering from head and neck cancer and who will undergo surgery will be included in this study. One week before the surgery the patients will undergo a CT-scan and a PET-scan with either of the tracers. Shortly before the surgery they will be given immunohistochemically detectable marker substances enabling the characterization of the tumor samples gathered from the resection specimen. These markers are pimonidazole for detection of hypoxia and iododeoxyuridine for detection of tumor cell proliferation. The data collected by PET-scan will be analysed and compared to the results acquired by immunohistochemistry.

66% of HNC patients present with advanced-stage disease at initial diagnosis. The 5-year survival rates for stages IVa, IVb, and IVc are 32%, 25%, and <4% respectively. Accurate pre-treatment staging is vital in determining the optimum procedure for the management of HNC. Early identification of non-responders may allow modification of their treatment through the introduction of more intensive therapies. Identifying prognostic factors that predict patient outcome will ultimately lead to new treatment regimens. Tumor hypoxia and proliferation are two key characteristics of cancer that were shown to correlate with poor response to treatment in HNC. In this proposal, the investigators assess the prognostic values of these two markers. Combining information from these two biological markers shall result in prognostic information superior to those of any of the two separately. Imaging those vital tumor characteristics simultaneously shall provide more coherent assessment of tumor microenvironment than does registration of corresponding images acquired in different imaging session, thus subject to uncertainties resulting from transient biologic changes and image registration process. The investigators propose to use a method that the investigators previously developed to simultaneously and non-invasively image tumor hypoxia (FMISO-PET) and proliferation (FLT-PET) within a single PET/CT study. CT Perfusion scan will be performed 1st, followed by PET imaging with staggered FMISO and FLT injections. FMISO and FLT signals will be separated retrospectively using kinetic modeling. The investigators believe imaging tumor hypoxia and cell proliferation simultaneously yield information underpinning for image-guided and radiobiological based dose painting, adaptive therapy, and patient medical management. If successful, this pilot study will constitute the basis for a NIH grant proposal that aims to improve treatment outcome assessment in HNC.

Head and Neck Squamous Cell Carcinoma (HNSCC) is the 6th most common cancer. Most cases are diagnosed in locally advanced stages, with treatment involving multimodal approach with combinations of radiotherapy, surgery and chemotherapy. The aggressive nature of HNSCCs and treatment modalities are associated with important acute and late toxicities that often promote temporary or definitive treatment interruption and may compromised the capability to tolerate subsequent treatments. Thus, the aim of this study is to analyze the acute and long-term impact of cancer treatment on quality of life, physical and cognitive function of HNSCC patients diagnosed with a locally advanced disease.
