Filter by:To assess the safety of preoperative combination therapy with KW-0761 (anti-CCR4) and ONO-4538 (anti-PD-1). To assess the behavior of immune cells in peripheral blood and tumor.
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 purpose of this study is to investigate the correlation between DNA methylation and the treatment and recurrence of oral cancer.
The purpose of this study is to determine the effects of a novel oral care protocol on the severity and pain of oral mucositis in patients receiving radiation and/or chemotherapy for head and neck cancers. The secondary objectives are to characterize the microbiome associated with oral mucositis, measure salivary proinflammatory cytokines, and evaluate other clinical indicators of the intervention. Participants will be enrolled prior to beginning radiation and/or chemotherapy, and will be randomized to receive either the oral health protocol or standard of care oral hygiene.
This study will fill a scientific gap in the current knowledge providing data for evaluation of the palatal augmentation prosthesis (PAP) 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 issues of oral cancer therapy, namely speech and swallowing functions. Patients will have been diagnosed with a cancer lesion on their tongue requiring surgery and removal of part of the tongue. Smaller cancers of the tongue are sized as T1 or T2. For patients with smaller lesions, a PAP, which can aid in speaking and swallowing is not routinely provided with the device.
45 individuals were subdivided into 3 groups, 15 patients with oral premalignant lesions, 15 patients with oral malignant lesions and 15 control individuals. Levels of chemerin and MMP-9 were evaluated in serum and saliva of these subjects utilizing the ELISA technique.
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 Role of microRNA-29b in the Oral Squamous Cell Carcinoma
The mortality rate of oral cancer in Taiwan is still high with no decrease. One of the reasons result in these situations is the patent visits hospital for treatment in late stage of oral cancer. Recently, the government makes effort in oral cancer screening to find oral potentially malignant disorders (OPMD) early. However, there is no conscience in treatment strategies of OPMD up to now. In this study, we will set a OPMD data bank, and use the cases to find out the potential biomarker, which is able to predict the oral cancer malignant transformation. Sixty OPMD with oral cancer transformation will be recruited, and 60 OPMD with no oral cancer malignant transformation will also be enrolled as the disease control group. Besides, 20 normal cases and 60 oral cancer cases resulting from previous OPMD will be collected. All those groups will detect the expression of p62/SQSTM1 to investigate the possibility that p62/SQSTM1 as a biomarker to predict the malignant transformation of OPMM, and a guideline to treat or not to treat OPMD.
