Active clinical trials for "Mouth Neoplasms"

To determine the prognostic implication of plasma Epstein-Bar Virus (EBV) DNA concentrations, as measured by quantitative polymerase chain reaction (PCR) in patients with nasopharyngeal carcinoma (NPC). To relate pretreatment plasma EBV DNA concentration to WHO classification of these tumors both in endemic and non-endemic areas. To determine whether pretreatment plasma EBV DNA can serve as a prognostic factor for both endemic and non-endemic patient populations.

These are ethnomedicine studies of plants used by rural and indigenous peoples for pain and oral inflammation relief.

This study aims to identify the accuracy of DNA integrity index in differentiating between oral premalignant lesions and oral cancer.

Employees are to be all screened for oral cancer in work place.

Aim: The current study targets linking serum and salivary dipeptidyl peptidase-4 with oral squamous cell carcinoma and comparing it with potentially malignant lesions and control to validate dipeptidyl peptidase-4 as a diagnostic marker for early detection of oral cancer and to reveal its possible role in carcinogenesis. Methodology: A total of 45 patients were recruited and subdivided into 2 groups: Group I: 15 patients having oral squamous cell carcinoma. Group II: 15 patients with potentially malignant lesions (leukoplakia and oral lichen planus) compared to 15 systemically healthy participants having no oral mucosal lesions acting as a control group (Group III). Serum and whole unstimulated salivary samples were collected from all participants to evaluate dipeptidyl peptidase level in different groups using enzyme linked immune-sorbent assay (ELISA) kit. ROC analysis was done to reveal area under the curve, sensitivity, specificity and diagnostic accuracy of DPP-4 among different groups.

Context: the oral cancer is the 5th cancer in order of frequency for human in France. It is the country where the mortality by oral cancer is the most raised in Europe. The most frequent location concerns the oral cavity prevalency of which is one of higher in the world. The main risk factors are the tobacco and the alcohol. The oral cancer is treated in the great majority of the cases by radiotherapy which is going to pull xerostomy, responsible for the degradation of the oral state. Furthermore, it will increase the risk of appearance of osteoradionecrosis (ORN) when the patient is carrier of buccal lesions and\or when he will have to undergo surgical acts. Consequently, the initial oral state of the patients is to be estimated so as to eliminate any source of the infection. An unfavourable initial state will increase the risk of degradation of this one and appearance of ORN. However, at present few epidemiological data are available concerning the oral state of the patients presenting an oral cancer. Objective: the main objective of this study is to describe, before radiotherapy, the oral state of the patients presenting an oral cancer and to follow the evolution of this oral state for three years and to register the patients quality of life. The secondary objectives are to describe the distribution of risk factors of the degradation of the oral state (oral hygiene, food habits, xerostomy, consumption of tobacco and alcohol) in this population and to register the impact of the dental restorations on the radiological assessment. Methods: this prospective epidemiological study of observation will be realized in the service of odontology of the Timone hospital (Marseille, France) in association with the services of ORL and maxillofacial surgery of Timone as well as the services of radiotherapy and medical oncology of Timone and Paoli Calmettes institute (IPC). All the toothed patients affected by an oral cancer untreated will be included, or treated surgically only, of more than 18 years old and for whom an initial dental assessment will be realized. The main assessment criteria will be the CAD index and the parodontal state. Expected results and perspectives: This study will allow to have epidemiological data concerning patients' oral state affected by an oral cancer before and after radiotherapy. It will allow to set up a consensus of good practice.

To obtain data to evaluate whether multispectral digital imaging can assist clinicians to screen for premalignant lesions in the oral cavity. Our system will illuminate tissue with monochromatic light to excite fluorescence, and polarized white light to generate reflectance, exposing abnormalities for real time, clinical diagnosis. Primary Objectives: To compare fluorescence images of oral mucosa lesions, obtained at 350 nm, 380 nm, 400 nm, and 450 nm excitation, to standard white light images and pathologic analysis of biopsied tissue. To compare reflectance images of oral mucosa lesion, obtained using broadband polarized light, to standard white light images and pathologic analysis of biopsied tissue. To develop algorithms to discriminate between normal and abnormal tissue To analyze images to determine which type of optical information (or combination thereof) yields the most diagnostically useful data

The purpose of this study is to investigate the correlation between DNA methylation and the treatment and recurrence of oral cancer.

JaW PrinT is a prospective observational cohort study evaluating the effectiveness of two different techniques of mandibular reconstruction.

Investigate the role of SDF-1/CXCR4 in the metastasis of oral squamous cell carcinoma
