Filter by:This is a prospective single arm single center Phase III study evaluating the ability of 18F-fluorocholine to detect the location of parathyroid adenomas.
Epidemiologic studies have revealed a tremendous increase in the prevalence of adrenal associated disease and related mortality worldwide. In order to meet all the therapeutic challenges in adrenal disease in China, CASE was founded in 2020. The objective of CASE is to launch an adrenal disease management model based on the Internet health information platform which allows the application and evaluation of adrenal disease treatment strategies at multiple centers. The proprietary electronic medical database will help the dynamic big-data analysis in epidemiology of adrenal disease, diagnosis, and treatment.
Most of the sporadic colorectal cancer (CRC )develop from colorectal adenoma (CRA), patients with CRA have a high risk of recurrence and development of metachronous CRA or CRC after removal, therefore, the investigators conducted this clinical trial to explore the chemoprevetion effect of metformin for CRA recurrence after removal.
We retrospectively analysed all TEM and TEM-ESD procedures that took place in Surgical Clinic of the Municipal Hospital of Karlsruhe and the Surgery Department of the University Hospital of Mannheim from 2007 to 2021. We evaluated the periopüerative and long-term outcomes of both procedures for adenomas, adenocarcinomas and other tumours seperately and we compared the results between the two techniques.
Early detecting and removing of colorectal advanced adenomas can reduce the incidence of colorectal cancer. Because of the less bleeding of advanced adenomas, sensitivities of the common used quantitative fecal immunochemical tests (qFITs) are unsatisfying. Ultra-sensitivity qFIT(us-qFIT) can determine extremely low fecal hemoglobin concentration compared with the common used qFIT. This study will prove the diagnostic accuracy of us-qFIT in detecting colorectal advanced adenomas.
This is an observational, prospective study using fecal DNA methylation test to define the risk of suffering from advanced adenoma or colorectal cancer (CRC) compared to colonoscopy and fecal immunochemical test (FIT). This study recruits at least 80 participants, including 40 people of healthy controls, 20 people with adenoma, and 20 people with CRC, which were confirmed by colonoscopy. All fecal specimens from participants will be examined by FIT and multi-methylated target gene detection through real-time quantitative methylation-specific PCR (qMSP). The objective of this study is to evaluate the sensitivity and specificity of multi-methylated target PCR compared with the FIT and confirm the examination results through colonoscopy.
A prospective multi-center observational study. The study will enroll eligible subjects from the United States to optimize the biomarker panel and evaluate the performance of a cfDNA marker panel selected by the Sponsor for CRC and advanced adenoma detection.
Comparison between a 1L of polyethylene glycol+ascorbic acid as a split dose and oral sulfate solution bowel preparation for colonoscopy study design: prospective, randomized, parallel, multi-center trial in 3 hospitals in Korea ( Seoul National University hospital, Seoul National University Bundang hospital, Seoul Metropolitan Government-Seoul National University ) patient inclusion criteria - aged 20-75 adults (out-clinic patients) scheduled for colonoscopy for any indication within the normal process of care
Patients scheduled for an endoscopic submucosal dissection(ESD) in the colorectum will be randomized to the use of a traction device(consisting of an endoscopic clip with a loop of dental floss secured in the lesion to be removed, another clip will anchor the loop to adjacent bowel wall) or a standard ESD.
The purpose of this study is to assess whether the use of large screen during colonoscopy will increase adenoma detection rate.
