Improved Implant for Reconstruction Purposes After Mandibular Resection
Head and Neck CancerOral CancerStudy design: A single center non-randomized, prospective clinical feasibility study. Study population: Study population is composed of 10 patients ineligible for a free-flap bone reconstruction. Intervention: The selected patients will receive the newly developed, patient-specific RIfRaM mandibular implant. Objective: The aim is to provide enough evidence through model analysis, physical tests and clinical study of 10 patients that our new type of personalized mandibular implant is safe to use, resulting in significantly fewer complications and can be practically placed during the surgery, without any complications. Main study parameters/endpoints: The study endpoint is to use the RifRaM without any implant related complications and a perfect mandibular fit.
Prosthesis Guided Speech Rehabilitation of T1/T2 Cancers of the Tongue
Tongue NeoplasmsTongue Cancer1 moreThis study will fill a scientific gap in the current knowledge providing data for evaluation of the palatal augmentation prosthesis as a therapeutic modality in a robust scientific randomized prospective clinical trial. Positive outcomes from this study have the potential to dramatically alter the most common morbidity of oral cancer therapy, namely speech and swallowing function in a population of patients with T1/T2 tumors of the tongue who are not currently routinely recommended for a palatal augmentation prosthesis.
Submandibular Gland Preservation in Neck Dissection
Neck DislocationOral CancerTrial design: a randomized controlled trial. Eligibility criteria for participants: patients with primary early stage oral squamous cell carcinoma. Exclusion criteria: cancer of the floor of the mouth. Interventions: submandibular gland is preserved during neck dissection for patients of the experimental group; submandibular gland is removed during neck dissection for patients of the control group. Primary Parameters: survival rate, mortality rate
Identification of Oral Lesions Through an Autofluorescence System
Oral LeukoplakiaAutofluorescence5 moreThe aim of the study will be to evaluate the efficacy of a tissue autofluorescence detection system as an aid to clinical screening in identifying lesions of the oral mucosa. The screening process will be performed by 3 clinicians with a different level of experience. Sensitivity and specificity tests will be conducted.
Serial Magnetic Resonance Imaging for the Prediction of Radiation-Induced Changes in Normal Tissue...
Malignant Oral Cavity NeoplasmMalignant Skull Base Neoplasm1 moreThis phase IV trial studies how well serial magnetic resonance imaging (MRI) after radiation therapy works in predicting radiation-induced changes in the normal tissue of patients with oral cavity or skull base tumors. Performing MRIs after radiation therapy for patients with oral cavity or skull base tumors may help to predict osteoradionecrosis (a change in non-cancerous tissue).
Predictive Value of GOCCLES® Device for Early Diagnosis of Oral Potentially Malignant Disorders...
Oral Potentially Malignant DisordersOral CancerOral potentially malignant disorders (OPMDs) are chronic pathologies which can suffer dysplastic alterations and evolve into oral cancer. The diagnosis of those pathologies is commonly done by visual inspection, which is not capable of determining the presence or not of dysplasia. Furthermore, this type of diagnosis depends greatly on the expertise and training of the professional. In recent years, new methods that can help early oral cancer diagnosis have been developed. A new device has been commercialized, named GOCCLES® (Glasses for Oral Cancer Curing Light Exposed Screening), based on the autofluorescence principle. The hypothesis of this study is that GOCCLES® device could be an effective tool to help in early detection of oral cancer.
Safety and Tolerability of the Use of Copaiba in Patients With Oral Cancer Submitted to Radiotherapy...
Head and Neck NeoplasmsMucositis Oral1 moreThis study aims to propose an alternative and auxiliary methodology for the prevention and treatment of Oral Mucositis (OM) in patients undergoing radiotherapy or radio and chemotherapy for head and neck neoplasms through the use of copaiba-based mouthwash, since the treatment that currently has proven efficacy for the prevention of OM(Low Power Laser Therapy) cannot be applied in tumor regions due to the risk of stimulating the tissue proliferation of malignant cells.
Prevention of Oral DNA Damage by Black Raspberries
Oral CancerSmoking2 moreThe purpose of this voluntary research study is to learn about the potential effects that black raspberry (BRB) lozenges may have on reducing the damage caused from cigarette smoke in mouth cells in adult smokers, which may be useful in reducing health risks associated with smoking.
Metformin for the Prevention of Oral Cancer in Patients With Oral Leukoplakia or Erythroplakia
ErythroplakiaOral LeukoplakiaThis phase IIb trial tests whether metformin works in preventing oral cancer in patients with oral leukoplakia (white patches) or erythroplakia (red patches). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount of glucose (sugar) in the blood. It decreases the amount of glucose patients absorb from food and the amount of glucose made by the liver. Metformin also increases the body's response to insulin, a natural substance that controls the amount of glucose in the blood. This trial may help researchers determine if metformin can stop changes in the mouth that are related to pre-cancer growths in the mouth.
A Fluorescent Tumor Marking Agent, Tozuleristide, for Imaging Oral Cavity Squamous Cell Cancer and...
Oral Cavity Squamous Cell CarcinomaStage I Lip and Oral Cavity Cancer AJCC v83 moreThis phase I/II trial studies the side effects of tozuleristide in imaging oral cavity squamous cell cancer and high-grade oral cavity dysplasia during surgery. Tozuleristide is an imaging agent that specifically binds to tumor cells. When exposed to near-infrared light, tozuleristide causes tumor cells to fluoresce (light up), so that surgeons may better distinguish tumor cells from healthy cells during surgery.
