Active clinical trials for "Mouth Neoplasms"

The objective of this study is to evaluate the relationship between serum nicotine levels and tumor response of squamous cell cancers of the head and neck (SCCHN) to radiotherapy alone or in combination with chemotherapy. Correlation of RECIST response, volumatic response, pathologic response (in patients receiving post-treatment neck dissection), and hemodynamic response (tumor oxygenation and blood flow) will be performed.

This is a non-randomized, phase II, open-label study. The goal of this clinical research study is to investigate how well sintilimab works in preventing high-risk oral premalignant lesions cancerization.

The presence of lymph node metastasis is an important factor in determining the appropriate treatment plan in patients with OSCC. However, detection of lymph node metastases by means of current imaging modalities is limited. 20-30% of patients with a clinically negative neck (cN0) harbour lymph node metastasis that were not detected during clinical diagnostic workup, which are referred to as occult lymph node metastasis. Therefore, patients with a risk of lymph node metastasis higher than 20% undergo a sentinel node procedure (SNP) or elective neck dissection (END), which means that a substantial part of patients is overtreated. There is need for an additional non-invasive diagnostic tool that can identify lymph node metastasis and thereby support the decision making for treatment of the neck. The main objective of this study is to evaluate if EGFR-positive cervical lymph node metastasis can be detected non-invasively with multispectral optoacoustic imaging using cetuximab-800CW as contrast agent in patients with oral squamous cell carcinoma.

PATH is a research study for cancer survivors to help participants to become more active. Studies suggested an association between inactivity and cancer. The investigators created new novel ways and technologies that may help participants to become more active. The three methods the investigators are studying are: 1) participant become active on her/his own; educational material will be provided; 2) working with a programmed health coach over the phone via text messages; and 3) using digital voice assist to help participant become more active. The digital voice assist will be delivered via Amazon Alexa on Echo speaker (it is the famous intelligent voice that you see in superball commercial by Alec Baldwin). This study is funded by the State of Maryland.

Background: - Normal bacteria and other tiny organisms (the microbiota) live in the mouth and nose. They contribute to human health in many ways, including digesting food and balancing hormones. Testing samples from the mouth can show how microbiotas are related to health and disease. However, the microbiota in a person's mouth differs depending on the methods of collection and the part of the mouth that is tested. Understanding what can change the microbiota (including mouth sites, and what a person eats or smokes) will give more information on how to study oral microbiota and smoking-related cancers and other diseases. Objectives: To see how smoking affects the microbiotas in mouth and nose. To determine which collection method for mouth specimens should be used for studying microbiota. Eligibility: Individuals at least 18 years of age who have been using tobacco products regularly for at least 5 years. Individuals at least 18 years of age who have never smoked. Design: Participants will be screened with a physical exam and medical history. Participants will have a dental exam. They will provide a saliva sample. The dentist will take swabs from the inside of the mouth, including the tongue, tonsils, gums, and teeth. The inside of the nose will also be swabbed. Participants will also fill out a questionnaire. It will ask about their history of smoking and consumption of alcohol, tea, and coffee. It will also ask about current medications, including antibiotics.

A feasibility study to compare the test characteristics of three different oral cancer screening techniques performed by trained primary health care workers:1)Unaided Visual Inspection, 2)VelScope Assisted Examination, and 3) Examination after application of Toluidine Blue dye.

The goal of this clinical research study is to evaluate an imaging technology that may help clinicians see how far an area of pre-cancerous or cancerous tissue extends in the mouth.

Recent studies have shown that dysregulation of ANXA1 expression are associated with tumorigenesis. Overexpression of ANXA1 protein is found in a wide variety of human tumors, such as breast 10, liver 11, pancreatic cancer14 and glial tumors15. In contrast, reduced levels of ANXA1 protein expression have been reported in ESCC4, 5, gastric6, breast7, head and neck SCC8 and prostate cancer9. No previous study on ANXA1 protein expression has been reported in the cancer of oral cavity. Furthermore, although alterations in annexin expression in different types of tumors have been described, no correlation has been established between ANXA1 and overall patient survival yet. ANXA1 is a major cellular substrate of the oncogenic tyrosine kinases such as EGF receptor and hepatocyte growth factor (HGF) receptor, c-met. Previously, we have shown that expression of HGF and c-met is significantly associated with the progression of OSCC in Taiwan. Kermorgant et al. recently showed that PKC controls HGF-dependent c-met traffic, signaling and cell migration. Prior study indicate that the mitogen phorbol-12-myristate 13-acetate (PMA) induced ANXA1 nuclear translocation in a PKCdelta-dependent manner and ANXA1 nuclear translocation may participate in the regulation of cellular proliferation and the differentiation. However, it is not known whether HGF can induce ANXA1 nuclear translocation or not and how this relates to the pathogenesis of oral SCC. In this study we aimed to investigate whether HGF induced the translocation of ANXA1 protein to the nucleus in OSCC cells and the role(s) of ANXA1 nuclear localization in the carcinogenesis of OSCC using an immunohistochemical technique. The data suggest a novel mechanism for HGF-induced ANXA1 protein nuclear translocation that may play an important role in the pathogenesis and prognosis in oral SCCs.

The purpose of this study is to correlate the results from a standard of care biopsy with CytID™ and hpvID™ swab tests for potentially premalignant and malignant oral lesions. The biopsy is considered standard of care and will be performed regardless of the patient's enrollment in the study. The study-related data gathering will not influence the treatment decisions of the clinician.

This purpose of this protocol is to evaluate and identify patients who may be eligible for actively enrolling NIH clinical research protocols for head and neck cancer; or provide standard evaluations and treatment necessary for patients with head and neck cancers enrolled in other NIH clinical protocols that do not include such treatment. Participants screened under this protocol will not be required to join a research study; the decision will be voluntary. Patients with head and neck cancer may enroll in this study. Participants may undergo various tests, described below, to determine their eligibility for participation in a specific clinical trial. Other tests may also be required, depending on the protocol or treatment for which the patient is being considered: Blood tests About 3 to 5 tablespoons of blood will be drawn for routine tests, HLA typing and hepatitis and HIV screening. Magnetic resonance imaging (MRI) This imaging procedure uses a powerful magnetic field to produce pictures of parts of the body in small section views. The test does not use radiation and may be done with or without a contrast dye material. Computerized tomography (CT) This procedure uses x-rays to produces three-dimensional images of body organs in small section views. A contrast dye may or may not be used. Positron emission tomography (PET) PET scans allow the doctor to see the activity of cells in specific body tissues. It requires injection of a radioactive material that attaches to a sugar fluid. The fluid goes to very active cells, such as cancer cells, revealing tumors. Pulmonary function tests These tests use a machine the patient breathes into to measure the volume of air the patient can move in and out of the lungs. Arteriogram, or angiogram The anatomy of the blood vessels can be seen using this procedure, which involves placing a small catheter (plastic tube) into an artery and injecting a contrast solution. Special X-rays are then taken to show the blood vessels. Endoscopy This procedure is done to evaluate the mouth and throat. A tube with a light on the end and special fibers is inserted down the throat to allow the surgeon to examine the throat and, if needed, biopsy a piece of tissue for microscopic study. The test is usually done under general anesthesia in the operating room. Biopsy A piece of tissue or tumor is removed for examination under the microscope. When a biopsy is done in the neck area, a small amount of anesthetic is injected into the area of the biopsy. The biopsy may be done with 1) a small needle to pull out some tissue, 2) a cookie-cutter-like instrument to punch out a small piece of tissue, or 3) a small knife to cut out a piece of tissue. A knife biopsy may be done in the operating room or the clinic depending on the location of the biopsy and precautions required. When the tests are done, the physician will discuss the results with the patient. Patients eligible for a research study will be offered participation. For those not eligible for a study, other therapies will be discussed and the patient will return to the care of his or her primary physician. In special circumstances, patients may be offered standard non-experimental treatment at NIH.
