Filter by:Prospective clinical study that analyzes the efficacy of colonoscopy assisted by an artificial intelligence system (DiscoveryTM) compared to virtual chromoendoscopy with iSCAN in the detection of colon dysplasia in patients with long-standing Ulcerative Colitis.
The purpose of this research study is to study a method to detect pancreatic precancer and cancer (ductal adenocarcinoma) using ultrasound technology in those who are at significantly increased risk for developing pancreatic cancer. The LINFU™ Technique is done by analysis of pancreatic fluid collected with the help of ultrasound. This is an investigational way to detect pancreatic precancers and ductal adenocarcinoma.
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.
This study aims to compare the expression of matrix metalloproteinases and their tissue inhibitors between 4 groups of patients defined according to the severity of the cervical lesion.
To determine if random biopsies can be safely eliminated from screening of average risk persons with IBD, the investigators propose to carry out a pilot randomized control trial in which targeted biopsies in combination with random biopsies will be compared to targeted biopsies alone in terms of pre-cancerous lesion capture rate, side-effects and CRC risk. The pilot study will aim to capture 20% of the overall study population in order to evaluate the feasibility of recruiting the needed number of participants in the specified time frame, while maintaining high quality of data collection.
Avmacol is an over-the-counter dietary supplement containing broccoli seed and sprout extracts in tablet form, hypothesized to activate protective cellular pathways including detoxication. In this study, participants who have been curatively treatment for head and neck cancer, will take Avmacol twice a day for 3 months.
This study is being done to see whether Avmacol®, a dietary supplement made from broccoli sprout and seed extract powder, induces changes in inner cheek cells that may be protective against environmental toxins such as tobacco. There are three main goals of the study: 1. To learn whether the dietary supplement, Avmacol®, can stimulate cheek cells to repair damage from environmental toxins; 2. to learn how the body metabolizes Avmacol®, by measuring its byproducts in the participant's urine and blood; 3. to learn whether the immune system can be stimulated by Avmacol®, by studying the natural killer cells and T cells in the participant's blood.
This pilot clinical trial studies how well a swallowable sponge cell sampling device and next generation sequencing work in detecting esophageal cancer in patients with low or high grade dysplasia, Barrett esophagus, or gastroesophageal reflux disease. Checking biomarkers in abnormal esophageal cells using a swallowable sponge cell sampling device and next generation sequencing may improve diagnosis and treatment of esophageal cancer.
This is a phase II randomized, double-blind placebo-controlled, crossover trial. The primary outcome of this trial is achieving durable eradication persistent high risk HPV infection determined by HPV negative test results achieved while on active treatment with AHCC and maintained for 6 month post supplementation and 12 months post completion of AHCC treatment compared to placebo.
To improve detection of esophageal (pre)malignant lesions during surveillance endoscopy of patients at risk of developing malignancies, for example in Barrett's Esophagus (BE), there is a need for better endoscopic visualization and the ability for targeted biopsies. Optical molecular imaging of neoplasia associated biomarkers could form a promising technique to accommodate this need. It is known that the biomarker Vascular Endothelial Growth Factor (VEGF) is overexpressed in dysplastic and neoplastic areas in BE segments versus normal tissue and has proven to be a valid target for molecular imaging. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labeling the VEGF-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye IRDye800CW. We hypothesize that when bevacizumab-IRDye800CW is administered, it accumulates in VEGF expressing high grade dysplasia (HGD) and esophageal adenocarcinoma (EAC), enabling early cancer visualization using a newly developed fluorescent NIR fiber-bundle. This hypothesis will be tested in this pilot intervention study.
