Active clinical trials for "Mouth Neoplasms"

Introduction: There are several manifestations in the oral mucosa resulting from antineoplastic treatments by chemo (QT) or radiotherapy (RT). In this study we will collect the variables referring to oral mucositis (OM), radiodermatitis, osteonecrosis of the jaws (ONJ), hyposalivation and xerostomia, dysgeusia, pain, oral candidiasis (opportunistic infection), trismus, quality of life, oral hygiene. MO and hyposalivation, which are related to damage to the salivary glands, are the most common manifestations, and ONJ is the most difficult to treat. The dentist can play an important role in prevention and treatment these oral lesions, directly influencing the patient's quality of life and adherence to antineoplastic treatment. Objectives: The main objective is to evaluate the efficacy of the intervention, using LLL phototherapy and topical Vit E, in the OM. And the intervention through LLL phototherapy and LPRP in the ONJ. These interventions will be performed by dentists during antineoplastic medical treatment. Material and methods: clinical trial, randomized, with balanced randomization, single-blind (for the evaluator of the results) with 2 experimental arms and a control group, carried out in a single center. Group 1, intervention with LLL phototherapy, Group 2, intervention with application of topical Vit E and Group 3, mouthwash with 0.12% chlorhexidine (usual clinical information). 360 patients will participate in this study from the Units of Oncology Medicine, Radiotetaphic Medicine and Oral Medicine, Oral Surgery and Implantology at the University of Santiago de Compostela. The segment of the patients will be given, an initial visit and returns every day that hears the application of antineoplastic treatment for the group of LLL phototherapy, returns of 15 days, one month, three months, six months, nine months and one year. In these return visits, evaluations and questionnaires will be carried out regarding all the variables that we will collect. Predictable results: If the application of laser phototherapy or topical Vit E contributes to the cessation, reduction or improvement of the clinical evolution of the manifestation of oral lesions, these treatments could be immediately implemented in our Oral Medicine unit and could lay the foundations for its implementation in different public centers and private.

An evaluation and validation study on oral cancer screening methods will be carried out, and two different methods will be used for oral cancer screening among the population. The two different methods are: (1) clinical observation (including inspection and palpation) combined with pathological biopsy. (2) Clinical observation (including inspection and palpation), in vivo staining (toluidine blue) combined with pathological biopsy. By evaluating and comparing the sensitivity and specificity of the two screening methods, the more effective oral cancer screening method will be selected.

This phase II trial studies the good and bad effects of the combination of drugs called cabozantinib and nivolumab in treating patients with melanoma or squamous cell head and neck cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help doctors determine how quickly patients can be divided into groups based on biomarkers in their tumors. A biomarker is a biological molecule found in the blood, other body fluids, or in tissues that is a sign of a normal or abnormal process or a sign of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. The two biomarkers that this trial is studying are "tumor mutational burden" and "tumor inflammation signature." Another purpose of this trial is to help doctors learn if cabozantinib and nivolumab shrink or stabilize the cancer, and whether patients respond differently to the combination depending on the status of the biomarkers.

The study will include patients with oral cancer and healthy controls of both sexes. Subjects having any systemic diseases or other types of cancer will be excluded. All subjects will be selected from Oral Medicine Department, Faculty of Dentistry, Al Ahram Canadian University and Fayoum University. Informed consent will be obtained from all subjects enrolled in this study after explanation of the whole procedure.

This case-control study aims to investigate if oral microbioma is associated with developing oral (pre)malignant disease.

The goal of this longitudinal study is to learn more about the articulatory consequences of surgical oral cancer treatment. The main aims are to study the coordination and development of speech articulation of patients who will undergo surgical treatment for oral cancer longitudinally and whether individual differences in the reliance on auditory or tactile information can predict the success of speech compensatory strategies. Participants will perform multiple speech tasks while motion tracking sensors track the articulatory gestures.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

The purpose of this study is to investigate post-operative and post-radiation upper esophageal sphincter opening measures in oral cancer patients, compare measures to age- and gender-matched healthy adults, and determine relationships with patient swallowing outcomes and quality of life.

Based on the recently identified mutations in HNSCCs, the major pathologic pathways implicated in the tumorigenesis of HNSCC include dysregulation of four processes: cellular survival and proliferation (e.g., TP53, EGFR, MET, and PIK3CA); cell-cycle control (e.g., CDKN2A and CCND1); cellular differentiation (e.g., NOTCH1); and Adhesion and invasion signaling (e.g., FAT1).7 TP53, EGFR, PIK3CA, CDKN2A, CCND1, and MET participate in several common signaling pathways. Alterations of these genes are most frequently seen in alcohol and tobacco-related HNSCC. However their role in prognostication and selection of therapeutics is not known

Micronuclei have been used since 1937 as an indicator of genetic toxic exposure due to their association with chromosomal alterations. They can be detected in exfoliated cells and used as an indicator of recent DNA injury within oral mucosa. The buccal epithelial cells are first to be interacted with the cancer compounds such as tobacco (nicotine), which in turn induces the frequency of micronuclei under the influence of saliva. The exfoliated cell micronuclei assay involves microscopic analysis of oral smears to determine the prevalence of micro-nucleation. The assay is reliable and technically easy to perform, noninvasive and sensitive with limited cost.
