View clinical trials related to Lynch Syndrome.
Filter by:Lynch syndrome (LS) is the most common genetic predisposition syndrome for colorectal cancer (CRC), responsible for around 2-4% of cancers. It is characterized by a pathogenic germline mutation in one of the DNA mismatch repair genes (path_MMR) MLH1, MSH2, MSH6, PMS2 or a deletion in the 3' region of the Epcam gene. Patients followed up for LS are at high risk of developing CRC at an early age, and have a high cumulative CRC risk. In this context, CRC screening by colonoscopy is of major importance, as it is associated with a reduction in both CRC incidence and mortality. In France, the Institut National du Cancer (INCa) recommends colonoscopy with indigo carmine chromoendoscopy (CE), as it is associated with a significant increase in the adenoma detection rate (ADR) compared with white light. However, EC is not routinely performed in clinical practice, as it is a time-consuming technique requiring a dedicated slot with a trained operator. Recent years have seen the emergence of artificial intelligence techniques for real-time polyp detection aids or CADe devices. These easy-to-use systems have shown very promising results compared with high-definition (HD) white light. Indeed, data from the first meta-analysis of 5 randomized controlled trials (4354 patients) confirmed a significantly higher ADD in the CADe group than in the HD group (36.6% vs. 25.2%; 95% CI], 1.27-1.62; P < 0.01; I2 Z 42%) 10. The CAD EYE system (Fujifilm) is a CADe device supporting both detection (sensitivity > 95%) and characterization of colonic polyps in real time. To date, artificial intelligence has never been evaluated for CRC screening in patients followed up for LS. The aim of this work is to evaluate the effectiveness of the CAD EYE system in this specific population. To this end, we intend to conduct a randomized, controlled, non-inferiority trial comparing CAD EYE with CE in patients with LS.
Combined hormonal contraceptives (CHCs), according to the opinion by The Manchester International Consensus Group, should be considered for women wishing contraception because also positively impact endometrial cancer and ovarian cancer risk. The awareness of the effects of hormonal therapies in women at high risk of developing endometrial cancer, colorectal, breast, or ovarian cancer, such as those affected by Lynch syndrome (LS), is currently limited, with few published studies addressing these populations. Making informed decisions about CHC use in this context necessitates careful consideration of individual cancer risk and the potential benefits and risks associated with CHC use. Accurate information regarding the oncological risks associated with CHC use is essential for facilitating shared decision-making between women and their healthcare providers in this patient population. This prospective study aims to evaluate the knowledge, attitudes, and beliefs of women with LS concerning CHCs and their potential effects on specific disease development and cancer risk, comparing them to the general population. By considering psychosocial factors and individual perceptions of cancer risk, this study seeks to contribute to informed decision-making, personalized counseling, and improved strategies for gynecologic cancer risk management in women with LS.
This research study is studying biomarkers in samples from patients with endometrial cancer. Studying samples from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
