Filter by:Lynch Syndrome increases Endometrial Cancer Occurrence in women due to failure in MisMatch Repair System. Lifetime Cumulative risk of developing endometrial Cancer is approximatively 40% in women with Lynch Syndrome. Endometrial cancer is the third women cancer in France. Many risk factors are known in general population. Lots of factors are related to over exposure to estrogen. Data about influence of general risk factors in Women with Lynch Syndrome are poor. Recently, a cohort study appears to have shown a significant decrease in the risk of endometrial cancer with multiparity, the use of hormonal contraception and late menopause in Lynch women. The impact of weight and certain metabolic parameters on the occurrence of endometrial cancers remains poorly known to this day.
The goal of this trial is to determine whether the Sage eConsent framework (presented using an electronic application) is non-inferior to traditional, paper-based, human-mediated consent-and therefore could be part of an acceptable population screening approach to identifying patients and others with actionable hereditary syndromes-and to increase basic knowledge about patients' informational needs about different aspects of genetic/omic screening. After receiving either 1) the traditional consenting approach, or 2) a consenting approach presented on an electronic tablet, the investigators will test for differences between these two arms in a variety of outcome measures including objective and perceived comprehension, time spent and informational needs, and enrollment decision, among others.
The aim of the present study is to compare polyp detection rates of LCI with high-definition white light endoscopy (HD-WLE) in patients with Lynch syndrome in a parallel, international, multicenter, randomized controlled colonoscopy trial
The purpose of this study is to determine the proportion of patients diagnosed with Lynch syndrome in colorectal cancer patients with the loss of staining by immunohistochemistry (IHC) of any of the mismatch repair (MMR) proteins. Besides, this study aims to test the specificity and the sensitivity of detecting microsatellite instability (MSI) by next-generation sequencing, and to find out the consistency between IHC and MSI in colorectal cancer patients in China. In addition, researchers want to analyze the clinical characteristics and germline mutation of Lynch syndrome in Chinese population.
The purpose of this study is to find out the proportion of patients diagnosed with Lynch syndrome in colorectal cacner patients meeting Chinese Lynch syndrome criteria. Besides, this study is aimed to analyze the clinical characteristics and germline mutation of Lynch syndrome in Chinese population.
Adenomas in Lynch syndrome have an accelerated progression to colorectal cancer (CRC) which might occur despite a regular follow-up. Despite low evidence, high-definition technology (HD) and indigo-carmine chromoendoscopy (CE) are recommended for surveillance in Lynch syndrome.The investigators will conduct a prospective multicenter randomized non-inferiority study. The principal aim is to compare the adenoma detection rate with WLE vs CE. Our hypothesis is that HD-white-light endoscopy (WLE) is not inferior to CE. Therefore - under expert hands - HD-CE does not add any significant advantage over HD-WLE on adenoma detection rate in patients with Lynch syndrome.
In this trial the investigators will evaluate the effectiveness of the implementation of a digital familial risk questionnaire in the detection of CRC patients with hereditary or familial CRC. This will be done using a stepped wedge design with 5 participating hospitals for a duration of 1.5 years. A comparison is made between an intervention phase (offering the online risk assessment questionnaire) and a control phase (hospital-based standard practice for the detection of CRC patients with hereditary or familial CRC, informed by the referral criteria that are being used in the intervention group). All patients with a diagnosis of CRC who have a first appointment at the CRC outpatient clinic will be included. The primary outcome is the percentage of all included patients who receive a recommendation for regular surveillance colonoscopies for himself/herself and/or relatives, provided by a clinical geneticist. Data from clinical geneticists is being used to answer this question.
This study compares two colonoscopy techniques (with Narrow Band Imaging versus with indigo carmine chromoendoscopy) in patients having Lynch Syndrome
This is an observational, case-control study evaluating the quantitative level of Septin9 in plasma pre- and post-colectomy in hereditary colorectal cancer (CRC) syndrome patients (Familial Adenomatous Polyposis (FAP), Lynch syndrome (also known as HNPCC), and Multiple Adenomatous Polyposis (MAP, also known as MYK/MYH) cases) and genetically related FAP-family members as controls and references.
This randomized phase Ib trial studies the side effects and best dose of naproxen in preventing deoxyribonucleic acid (DNA) mismatch repair deficient colorectal cancer in patients with Lynch syndrome. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of naproxen may keep cancer from forming in patients with Lynch syndrome.
