Filter by: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.
The purpose of this study is to examine how people with a family history of colon cancer and other related cancers respond to recommendations for cancer screening after genetic counseling. The purpose of your participation would be to help us learn more about whether people with a personal and/or family history of colorectal cancer and other cancers follow cancer screening recommendations.
The goal of this study is to create a registry of information about women who have or are at risk for Lynch syndrome, in order to study gynecologic cancer risks. This is an investigational study. Up to 1000 patients will take part in this study. All patients will be enrolled at MD Anderson.
This randomized phase III trial studies oxaliplatin, leucovorin calcium, fluorouracil, and bevacizumab to see how well they work compared to oxaliplatin, leucovorin calcium, and fluorouracil in treating patients who have undergone surgery for stage II colon cancer. Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving combination chemotherapy together with bevacizumab is more effective than combination chemotherapy alone in treating colon cancer.
