Filter by:This study will determine systemic vitamin A status and lesion histopathology of participants with vocal fold hyperkeratosis resulting in clinical leukoplakia.
The study was designed as a prospective, multicenter, randomized, open-label, parallel-controlled clinical trial. The study population was patients with vulvar leukoplakia, and compared the efficacy and safety of AI temperature-controlled radio frequency technology and electrical stimulation in the treatment of vulvar leukoplakia. According to the research purpose, the sample size was calculated and determined to be 120 cases, and they were randomly assigned to the observation group and the control group according to the ratio of 1:1, namely 60 cases in the radio frequency observation group and 60 cases in the electric stimulation control group.
This phase IIb trial tests whether metformin works in preventing oral cancer in patients with oral leukoplakia (white patches) or erythroplakia (red patches). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount of glucose (sugar) in the blood. It decreases the amount of glucose patients absorb from food and the amount of glucose made by the liver. Metformin also increases the body's response to insulin, a natural substance that controls the amount of glucose in the blood. This trial may help researchers determine if metformin can stop changes in the mouth that are related to pre-cancer growths in the mouth.
This research protocol is comparing the effectiveness of surgical excision to the "wait and see" approach for the management of oral leukoplakia and erythroleukoplakia in prevention of oral squamous cell carcinoma onset.
Synucleins are a family of small, highly conserved proteins found in vertebrates and are specially abundant in neurons particularly in presynaptic terminals (Surguchov et al., 2001). Gamma-synuclein is the third member of the synuclein family, and is predominantly found in the cytosol of tumor cells and functions both intra- and extra-cellularly. It is involved in the pathogenesis of different types of cancer and some neurodegenerative diseases (Liu et al., 2018). Smoking - a major risk factor for oral cancer and its progression - and nicotine-containing products were found to time-dependently up-regulate the Gamma-synuclein expression in cancer cells (Hsu et al., 2020a). Gamma-synuclein is released from tumor cells and was found to be elevated in tumors such as urinary bladder cancer (Liu et al., 2016), colorectal cancer, gastric adenocarcinomas and esophageal cancer (Liu et al., 2012). It is present in blood, serum, cerebrospinal fluid and saliva. The detection of extracellular synucleins in body fluids can reveal the first steps of the disease thus it can be used as a potential tool for early cancer detection (Surguchov, 2016). This study aims to identify the diagnostic accuracy of Gamma-synuclein in differentiating between oral malignant lesions and oral premalignant lesions.
This study aims to determine the correlation between candida and pro- inflammatory cytokines response in Oral Leukoplakia(OL) with antifungal therapy. Ethical clearance from the Institutes ethical committee and Informed written consent from the patient will be obtained. The study group would comprise of clinically and histopathologically confirmed cases of OL (60 patients). The control group would be 30 dental patients ( age & sex matched) who do not any malignancy, OL or any other potentially malignant disorder of oral mucosa. Patients who have any predisposing factor for oral candidiasis will be excluded from the study. Swabs will be taken from the oral lesion and cultured for candida to determine phenotypes, virulence attributes and antifungal sensitivity. Sterile PVA opthalmic sponges will be used to collect sample from the surface of oral epithelium and then processed to determine levels of pro- inflammatory cytokines (IL-6, IL-8. IL-17, TNFα). This procedure will be repeated in study group 2 weeks after a course of antifungal therapy. The results will be tested statistically at a confidence level of 95%.
This study will be conducted to obtain data on oral cancer risk factors to generate machine learning models with good predictive accuracy for stratifying individuals with high-oral cancer risk and delineating high-risk and low-risk oral lesions. Likewise, this study will seek to provide oral cancer-related health education and training on oral-self-examination for beneficiaries
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.
Oral leukoplakia is the most commonly occurring oral premalignant disorder. It has an overall prevalence rate of 1-4% with highest prevalence rate of 10.54% in Asian countries. The management of leukoplakia includes conventional as well as surgical modalities. The conventional approaches include Beta Carotene, Lycopene, ascorbic acid, alpha tocopherol, retinoids. But, no significant results are documented on regression rate and prevention of recurrence of the lesions. Melatonin chemically N-acetyl-5-methoxytryptamine is a hormone produced in the pineal gland. It is synthesized from the amino acid, tryptophan. The basic physiological function of melatonin is to control day night cycle and hence is commonly used in insomnia, jet lag and some other psychological disorders. Melatonin has a potent antioxidant effect and other actions such as modulation of cell cycle and induction of apoptosis, inhibition of telomerase activity, inhibition of metastasis, prevention of circadian disruption, anti-angiogenesis and stimulation of cell differentiation To date, no treatment modality has demonstrated its clear superiority for leukoplakia. There are many pathways by which melatonin can be used beneficially for management oral leukoplakia.
Background: Oral epithelial dysplasia (OED) is a condition with an increased risk of oral cancer. Due to the current changes in the factors associated with these diseases (because of human papillomavirus), it is expected that those who have no history of smoking or alcohol, young (<50 years old), and white male would be commonly affected. Those individuals require a higher need for information, preferred a more active role in decision-making, and have a longer lifespan than older individuals. There remain no detailed studies of whether the informational needs delivered to patients with OED met their needs or indeed what information such patient may wish. A few tools are available to evaluate the IN of patients with head and neck disorders. However, the items of these instruments were dedicated to a particular disease (e.g. cancer) and hence are not applicable to be used for OED. Project aims: To evaluate the psychometric properties of the Oral Epithelial Dysplasia Informational Needs Questionnaire (ODIN-Q), developed and revised in the preliminary work for the proposed study, in a cohort of patients with OED. Timescale: 19 months. Clinical significance: This questionnaire can be useful in clinical practice. It could help to meet the patient's information needs and plan educational interventions for those showing unmet needs.
