Filter by:This is a follow up study which aims to evaluate the correlation between several methylated genes (potential biomarkers) and oral cancers. A prospective case control trial is designed with sample size of at least 300 cases with estimated 200 subjects with precancerous lesion or oral cancer, and 100 subjects with normal oral mucosa. This study is approved by the National Taiwan University Hospital Research Ethics Committee. After signing the informed consent, all subjects will receive an intraoral examination and followed by epithelial cells collection with oral swab. The gDNA will be extracted from the oral swab collected cells and followed by bisulfite conversion procedures. Subsequently, bisulfite converted DNA will be subjected to methylated gene detection by Real-Time PCR. The methylation index (clinical sensitivity and specificity) of oral cancer related genes will be evaluated. For diagnosis confirmation, photos and biopsy specimens will be taken upon observation of abnormal lesion.
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.
The goal of this clinical research study is to find the highest tolerable dose of the combination of alisertib and TAK-228 that can be given to participants with advanced solid tumors that are associated with HPV. Researchers also want to learn if the study drug combination can help to control advanced solid tumors.
This phase II trial studies how well radiation therapy with or without cisplatin works in treating patients with stage III-IVA squamous cell carcinoma of the head and neck who have undergone surgery. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known if radiation therapy is more effective with or without cisplatin in treating patients with squamous cell carcinoma of the head and neck.
The purpose of this study is to investigate the correlation between DNA methylation and the treatment and recurrence of oral cancer.
The aim of the study is to investigate post-surgery sensory impairment and life quality changes in oral cancer patients who underwent free flap (Free Flap) on post-operative 6 months, 12 months, and 24 months, respectively
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 aim of this study is to evaluate the association between several methylated genes and oral cancers. A prospective case control trial is designed with sample size estimated at least 160 cases. It is expected to enroll at least 100 subjects with precancerous lesion or oral cancer, and ~60 subjects with normal oral mucosa. This study is approved by the National Taiwan University Hospital Research Ethics Committee. After signing the informed consent, all of the subjects will receive an intraoral examination and the oral epithelial cells will be collected. If abnormal oral lesion is observed, it will be photographed, and the biopsy will be performed to confirm the diagnosis. For methylated gene detections, the gDNA will be extracted from the collected cells and standardized assay will be performed. Clinical sensitivity and specificity for these methylated genes will be evaluated.
