Active clinical trials for "Mouth Neoplasms"

The purpose of this study is to get images (pictures) of oral lesions, which occur inside the mouth, before the patient's surgery using a special camera. These pictures will be used in our research to evaluate a new technology that uses a laser and takes pictures of the microscopic structure of tissue. The technology is called "reflectance confocal microscopy." We would like to compare what the camera sees to biopsies (pathology) of the same area. We will evaluate the pictures obtained from the patient to determine whether this technology may be useful in the future. We hope this technology can be used as a tool for early diagnosis of oral cancers and for guiding surgery.

The purpose of this observational study is to evaluate the utility of the S100A7 immunohistochemistry signature-based assessment - STRATICYTE - in determining the risk of progression to cancer of clinically suspicious oral lesions.

The aim of this prospective non-interventional multi-center trial is to study the prognostic value of intratumoral and systemic immune biomarkers in newly diagnosed non-metastatic head and neck cancer. Furthermore, the local immunological processes in the tumor will be correlated with the systemic immune status determined in the peripheral blood to identify prognostic immune signatures. In addition, tumor organoids will be generated ex vivo for functional biological analyses. The main objective is to create a prognostic score determined by clusters based on tumor immunologic criteria.

This clinical trial studies widefield fluorescence and reflectance imaging, fluorescence spectroscopy, and tissue samples in regularly examining (monitoring) participants at risk for developing oral cancer. All tissue and cells are made of tiny particles. Some of these particles give off small amounts of light. This light is called fluorescence. Fluorescent imaging use instruments that shine different wavelengths (colors) of light in the mouth taking fluorescence pictures through a portable head light or by taking fluorescent and reflectance pictures through a dental microscope using a digital camera. Fluorescent spectroscopy uses a small probe placed gently against the lining of the mouth and the tissue is exposed to small amounts of fluorescent light that is then collected with a special camera and a computer to be analyzed. Checking mouth tissue samples under a microscope may also help detect abnormal cells. Diagnostic procedures, such as fluorescence and reflectance imaging, fluorescence spectroscopy imaging, and tissue samples, may help doctors detect pre-cancer or early cancer when it may be easier to treat.

The goal of this clinical trial is to compare the effectiveness of a navigation-based multilevel intervention (ENDURE) with treatment as usual at decreasing delays starting guideline-adherent postoperative radiation therapy among patients with head and neck cancer. The main questions the trial aims to answer are: Does ENDURE decrease delays starting PORT relative to treatment as usual? What are the mechanisms through which ENDURE reduces treatment delays? What are the barriers and facilitators to implementing ENDURE across diverse clinical settings?

The purpose is to determine the extent of genetic damage in oral mucosal lesions ascertained in the study, whether specific genotypes are associated with genetic damage observed in the oral mucosal lesions, whether the extent of genetic damage changes over time, and what factors (e.g. smoking) contribute to those changes. Genetic damage indicators will include among others DNA adduct formation, particularly related to tobacco smoke carcinogens such as polycyclic aromatic hydocarbons. The genotypes of interest will be focused on these affecting carcinogen metabolism, (e.g., (CYP family), but may also include those related to growth factors, cell cycle control, and DNA repair. Microsatellite instability is another key indicator of damage that we plan to examine. This study was undertaken due to the paucity of data on the types of oral lesions seen in general dental practice and the limited knowledge of the natural history of these lesions. Persons were enrolled who had red and/or white oral lesions identified at 6 Dental Clinics at VA Medical Centers. The VA Centers involved were: Washington, DC; Atlanta, GA; Durham, NC; San Francisco, CA; Danville, IL; and San Antonio, TX. When a dentist found a red or white lesions in the course of routine outpatient examinations and care, obvious causes such as denture frictional lesions could be ruled out, and the normal standard of care for the lesion was biopsy, the patient was considered for enrollment into the study. The study was described to the patient, the consent for was signed, the patient received an intraoral examination to identify and characterize the oral lesions, the lesions were photographed, an oral epithelial cell sample was taken from the site and from the rest of the oral mucosa, and the patient was interviewed using a standard questionnaire that requested information about sociodemograhic, medical, and lifestyle factors, particularly tobacco and alcohol use all as part of the study protocol, and the patient received a biopsy as part of normal care. The biopsy report was obtained as was a small piece of the biopsy material that was not needed for patient diagnostic purposes. The subjects returned every 4-6 months for reassessment of the lesion or to determine that the lesion had not returned. The patients completed a questionnaire at each of these visits so that lifestyle factors such as tobacco and alcohol use could be reassessed. Also oral epithelial cell scrapings were obtained at each of these visits. This study is particularly valuable because longitudinal data was collected and because the data were collected over time using standard procedures.

Objectives: To study the effect of anti-angiogenesis therapy on reducing the recurrence of high-risk oral cavity cancer patients after curative local treatment. To study the toxicity and compliance of post-operative anti-angiogenesis therapy Study design: This is a multi-center randomized controlled phase II/III two-stage study. Study endpoints: The primary endpoint is the tumor-free survival (primary and second primary malignancies) and the primary analysis is to compare the tumor-free survival between groups.

Primary Objectives: To determine the maximum tolerated dose and transduction efficiency of adenoviral mediated wild type p53 gene transfer in premalignancies of the upper aerodigestive tract. To determine the efficacy of single agent adenoviral mediated wild type p53 gene transfer in reversing oral premalignancies.

This is a Phase II study designed to test the efficacy of chemotherapy with docetaxel, cisplatinum (cisplatin) and 5-fluorouracil in patients with squamous cell carcinoma of the oral cavity to determine what effects these agents may have on cancer cells.

The purpose of this study is to determine the safety, effectiveness, and recommended dose of Proxinium in North American patients with Squamous Cell Head and Neck Cancer
