Active clinical trials for "Mouth Neoplasms"

The current project is based on the assumption that a diagnosis of human papillomavirus associated Infiltrating Carcinomas can be made from a blood sample for patient with Cervical Cancer, Vulvar Cancer, Anal Cancer, Oropharynx Cancer, Oral Cavity Cancer or Penis Cancer at any stage of the disease and including surgical treatment for the small tumors.

The purpose of the proposed research project is to evaluate and enhance the feasibility and acceptability of integrating a tele-mentoring component into the identification of oral lesions at the 6 dental clinics of Family Health Centers at NYU Langone (FHC), a Federally Qualified Health Center (FQHC) in Brooklyn, NY.

The goal of this clinical research study is to learn how a new method for performing oral (mouth) exams can help doctors check for suspicious lesions (called premalignant and malignant oral lesions [PMOL]) in the mouth of HIV-infected smokers.

There is no consensus on the indication of postoperative radiotherapy for early stages oral and oropharyngeal squamous cell carcinoma with complete pathological resection and no neck node metastasis, but most of the institutions do not give any post-operative treatment. Loco-regional control rates range between 80-85% at five years. Surgical margins molecular analysis for microsatellite instability (MSI) marker could help to select the high-risk patients who should receive postoperative radiotherapy. We expect to include 120 patients in five years and have 60 informative tumors for MSI marker. Patients with positive molecular margins will receive postoperative radiotherapy (50 Gy). Patients with negative molecular margins will not receive radiotherapy.

Prospective study of diagnosis validation of a cytological technique. 200 patients with oral cavity cancerous and precancerous lesions will be enrolled. A cytological sample of the lesion will be performed by transepithelial brushing ( Orcellex® Rovers brush) in cytology liquid-based technology (methode ThinPrep 2000 (Hologic®)). A microscopic double blind reading will be performed. A biopsy sampling will be carried out in accordance with current strategy of screening. The brushing diagnosis quality will be compared to the biopsy which is the gold standard.

In this study the investigators are conducting research to determine whether a new optical device using polarization reflectance spectroscopy can help doctors or dentists identify abnormalities in the mouth that require follow-up. To establish this, measurements are needed from a large number of individuals with different abnormalities in their mouth. The investigators believe the proposed approach has potential to improve and enable mass screening for precancerous and early cancers of the oral cavity by improving the predictive value of oral cavity exams, particularly for less experienced practitioners. The information from this study will be compared to results from the pathology report of the tissue taken from your mouth. Hypothesis: Polarized reflectance spectroscopy can distinguish high-risk oral lesion from normal and reactive oral lesions. Polarized reflectance spectroscopy can capture low-grade oral lesions that have characteristics associated with a high risk of progression to cancer.

uPAR PET/CT for Staging Advanced and Localised oral and oropharyngeal cancer

Evaluation of the metformin drug effect as a drug that found to improve the quality of tissues, decrease signs & symptoms of cancer, and decrease histo-pathological criteria of dysplasia. This will be done by the aid of measuring salivary Micro RNA 31 & 210 in saliva in addition to measure cyclin A2 as an immuno-histochemical analysis.

investigating the level of malondialdehyde (MDA) & nitric oxide (NO) in saliva in oral premalignant and malignant lesions in order to determine their diagnostic value for the malignant and potentially malignant lesions.

This research may help dentists or surgeons to better detect areas in the mouth that are either prone to cancer or are early cancers. The earlier the detection on cancer in the mouth, the better the chance that treatment or prevention can be more effective.
