Filter by:Lynch syndrome (LS) is an inherited cancer predisposition syndrome caused by pathogenic germline variants in DNA mismatch repair (MMR) genes. New cancer screening and diagnostic tools are urgently needed to identify LS-related cancers early enough for curative treatment. Urothelial cancers (comprising bladder and upper tract urothelial tumors) are the third most common cancer after colorectal and endometrial cancers in individuals with LS. Up to one in four LS individuals will develop urothelial cancer during their lifetime, with the risk varying based on the defective MMR gene. In this clinical trial, we will employ urine tumor DNA (utDNA) to identify asymptomatic urothelial cancers in Lynch syndrome patients, and to investigate the potential benefits of urine tumor DNA based screening in this high-risk population.
ICED is a prospective sample collection research study, aiming to develop or validate a blood/urine biomarker which could potentially detect cancers early in individuals at high risk of developing cancers, due to certain germline alterations.
Lynch Syndrome, an inherited condition, increases bowel cancer risk. People with Lynch Syndrome are recommended to have regular colonoscopies where a camera in a tube is used to look inside the bowel for cancer and for polyps (growths that sometimes can become cancerous). UK guidelines recommend that people with Lynch Syndrome have colonoscopy check-up every 2 years after reaching a certain age; however, they face many challenges which make it difficult to have the recommended check-up. Among a subset of people with Lynch Syndrome in England, this study will investigate the: - percentage who are having colonoscopy check-up as recommended by UK guidelines - factors influencing whether a person is more/less likely to have the recommended colonoscopy check-up - views, experiences, and challenges of living with Lynch Syndrome and colonoscopy check-up This study will collect information from people in the 'Lynch Syndrome registry pilot' using a questionnaire. The Cancer Screening and Prevention Research Group (CSPRG) at Imperial College London are conducting the Lynch Syndrome registry pilot, which is recruiting people with Lynch Syndrome who are aged >18 years and in the Cancer Prevention Programme 3 (CaPP3) trial, from Nov 2022-Nov 2023. This study will include people in the Lynch Syndrome registry pilot who provided consent on the registry pilot consent form to be contacted about future research and are aged ≥25 years. People who have had previous surgery to remove their rectum will be excluded. The investigators will use the 'Views, experiences, and challenges of colonoscopy check-up' questionnaire, together with a few pieces of additional information previously collected as part of the Lynch Syndrome registry pilot. Participation involves completing the questionnaire only. The study will take approximately one year from administering the questionnaire to sharing results with participants.
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.
Background Lynch syndrome is caused by a pathogenic variant in one of the four Mismatch Repair genes (MMR): MLH1, MSH2/Epcam, MSH6, or PMS2. These pathogenic variants confer a higher risk of developing colorectal and other cancers, including small bowel cancer. The risk of developing a small bowel adenocarcinoma is about 100 times higher compared to individuals without Lynch syndrome, and the lifetime risk of small bowel cancer is estimated at 4,2%. The diagnosis of a small bowel cancer depends on videocapsule endoscopy (VCE). This device is swalled so that it can record images of the small bowel, which are then stored on a wearable device for about 8 hours. The capsule is then expelled in the feces while the images are transferred to a computer to be analysed. To date, there is conflicting evidence on the efficacy of small bowel cancer screening with VCE Rationale: this registry study will collect prospective data from patients with LS undergoing VCE Aim: evaluate the incidence of neoplastic and pre-neoplastic lesions in patients with LS during a VCE-based small bowel cancer screening study Design: this is a multicentric, observational study that analyzes data from diagnostic techniques already approved. Patients will not undergo diagnostic procedures beyond what would be recommended by clinical practice.
The long-term goal of our PIC is to develop effective strategies that can be applied clinically at the point-of-care to prevent, intercept, or detect PDAC at an early stage, thereby reducing PDAC burden and saving lives.
This is a community-based study requiring participant-self-enrollment, that can help to increase the rates of genetic testing among the family members of people who have been diagnosed with a hereditary cancer syndrome. The two main factors in this study are the IGNITE-TX intervention (website and navigator) and the free genetic counseling and testing. The IGNITE-TX Intervention is an innovative multi-modal intervention, with two components: a) interactive web "IGNITE-TX Hub" and b) genetic family navigators.
Prospective multicenter registry study to assess the frequency of Lynch syndrome among patients with colorectal cancer in Russia
This phase IIb trial tests whether Tri-Ad5 in combination with N-803 works to prevent colon and other cancers in participants with Lynch syndrome. Each of the three injections in Tri-Ad5 vaccine contain a different substance that is in precancer and cancer cells. Injecting these substances may cause the immune system to develop a defense against cancer that recognizes and destroys any precancer and cancer cells that produce these proteins in the future. N-803 may increase immune responses to other vaccines. Giving Tri-Ad5 in combination with immune enhancing N-803 may lower the chance of developing colon and other cancers in participants with Lynch syndrome.
