Filter by:The purpose of the Ohio Colorectal Cancer Prevention Initiative (OCCPI) is to reduce morbidity and mortality due to colorectal cancer (CRC) in the state of Ohio. By identifying individuals at high-risk for CRC (genetically predisposed) and providing screening recommendations for cancer risk reduction, the OCCPI will understand how to increase length of life and quality of life for those diagnosed with CRC in Ohio, as well as to better prevent CRC in others in Ohio. Participants will have free tumor screening for Lynch syndrome, and may be eligible for free genetic testing and free genetic counseling as part of this study.
A clinically applicably strategy for molecular screening for Lynch Syndrome is being implemented in Denmark. Based on sequential analysis with immunohistochemistry and methylation analysis, patients with possible hereditary colorectal cancer are identified. These patients are offered genetic risk assessment and counselling. The study hypothesis is that molecular screening will identify more patients with Lynch Syndrome than the family history alone. Prospective data collection is performed using established clinical databases.
Hereditary non-polyposis colon carcinoma (HNPCC or Lynch-Syndrome) is a rare cause of colorectal cancer caused by a gene defect in the so -called mismatch repair genes. Patients can present at young age with colorectal cancer and polyps can develop faster to malignant lesions in comparison to classical sporadic adenomas. New advanced imaging modalities with high definition images and virtual chromoendoscopy have a theoretical advantage to improve detection and to increase polyp detection. In patients with HNPCC polyp detection has been shown to be increased by classical chromo-endoscopy and by high definition endoscopy with narrow band imaging (NBI) (a virtual chromo-endoscopy modality activated by a button on the endoscope), in comparison to white light endoscopy. However, in these back-to-back studies there was no randomization for the order of imaging modality. It is therefore not clear whether really the image enhancement adds to increased polyp detection or if this is achieved by a second inspection of the mucosa. In this trial the investigators want to assess the real additional value of virtual chromo-endoscopy for polyp detection in patients with the Lynch syndrome. The investigators will use the high definition pentax system and will compare white light endoscopy to i-scan, the incorporated virtual chromo-endoscopy mode in this system.
The investigators research mobilizes the resources of an integrated health-delivery system with extensive electronic clinical data to implement and evaluate a new strategy to maximize screening of Colorectal Cancer (CRC) patients for Lynch Syndrome.
A clinically applicably strategy for molecular screening for Lynch Syndrome has been implemented in the Region of Southern Denmark. Based on sequential analysis with immunohistochemistry and methylation analysis, patients with possible hereditary colorectal cancer are identified. These patients are offered genetic risk assessment and counselling. The study hypothesis is that molecular screening will identify more patients with Lynch Syndrome than the family history alone. Prospective data collection is performed using established clinical databases.
Lynch syndrome (LS), or hereditary nonpolyposis colorectal cancer (HNPCC), is a hereditary disorder predisposing for colorectal cancer. To reduce the risk of colorectal cancer, patients undergo colonoscopy every 1-2 years. Chromoendoscopy is relatively new technique which improves the detection of adenomas, the precursor lesions of colorectal cancer. The aim of this study is to determine whether chromoendoscopy, including polypectomy of all detected lesions, reduces the development of colorectal neoplasia and the need for colectomy in LS patients.
Lynch syndrome (LS), or hereditary nonpolyposis colorectal cancer (HNPCC), is a hereditary disorder characterized by a very high risk of early-onset colorectal and endometrial cancer and an increased risk of other cancers, including cancers of the stomach, ovary, urinary tract, hepatobiliary tract, pancreas and small bowel. This is a national multi-centre study evaluating the yield of small bowel screening using capsule endoscopy (CE) and double balloon enteroscopy (DBE) in Lynch syndrome subjects. The intervention consists of performing a capsule endoscopy procedure at baseline and at 2-year follow-up. In patients with polyps or malignant appearing abnormalities on capsule endoscopy, double balloon enteroscopy will be performed with subsequent endoscopic or surgical removal of neoplastic lesions. The aim of the study is to determine the prevalence and incidence of small bowel neoplasia in Lynch syndrome patients using small bowel CE and DBE.
After informed consent, participants will be asked to complete a medical/family history questionnaire and provide a blood sample. Participants will also be asked for their permission for study investigators to access medical records and/or recontact them for updates to their medical and family histories. Data and biospecimens will be stored for potential future research projects.
Cancer genetic counseling (CGC) has been found to have "substantial" benefits for individuals with breast cancer and their family members; it has been deemed by multiple organizations as "standard of care" for women with breast cancer and their relatives. Unfortunately, there is a disparity in access to CGC, especially among women who live in rural and underserved areas. In North Carolina, only two cancer genetic counselors practice in rural clinics - each only for a few days per month. Therefore, in an effort to make CGC more widely available in a timely manner, we propose to test provision of counseling through telemedicine (TM), in which a patient and health care provider communicate with each other using videoconferencing. In 4 rural oncology clinics, we will implement low-cost TM and compare satisfaction and cost-effectiveness between groups of women designated to have their CGC session by TM or FTF. We'll use a validated measure to assess satisfaction by a phone survey one week after the CGC appointment; cost-effectiveness will be measured at project's end by calculating length of wait time for appointment and costs of equipment, labor, and mileage. Study hypothesis: TM is as satisfactory as FTF counseling and is a more cost-effective way to provide this beneficial service.
