Filter by:This phase II trial studies the side effects of erlotinib hydrochloride and how well it works in reducing duodenal polyp burden in patients with familial adenomatous polyposis at risk of developing colon cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
The primary objective of this chart review study is to evaluate the outcomes of subjects with Attenuated Familial Adenomatous Polyposis (AFAP) and Deleterious Familial Adenomatous Polyposis (FAP) who have not undergone surgical resection of the colon. A secondary objective of this study is to compare 1) the colonoscopic and pathology histories including history of ampullary adenoma in the duodenum over family generations, 2) the use of chemopreventive medications, and 3) clinical features of subjects who pursued prophylactic surgical resection of the colon with those that have elected to continue routine colonoscopic surveillance in an effort to better characterize factors (e.g. polyp burden, ampullary adenoma and level of dysplasia, etc) which may influence management decisions.
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.
There is a need for better visualization of polyps during surveillance endoscopy in patients with hereditary colon cancer syndromes like Familial Adenomatous Polyposis (FAP) and Lynch Syndrome (LS), to improve the adenoma detection rate. Optical molecular imaging of adenoma associated biomarkers is a promising technique to accommodate this need. The biomarker Vascular Endothelial Growth Factor (VEGF) is overexpressed in adenomatous colon tissue versus normal tissue and has proven to be a valid target for molecular imaging. The University Medical Center Groningen (UMCG) developed a fluorescent tracer by labeling the VEGF-targeting humanized monoclonal antibody bevacizumab, currently used in anti-cancer therapy, with the fluorescent dye IRDye800CW. The investigators hypothesize that when bevacizumab-IRDye800CW is administered to patients, it accumulates in VEGF expressing adenomas, enabling adenoma visualization using a newly developed near-infrared (NIR) fluorescence endoscopy platform (NL43407.042.13). This hypothesis will be tested in this feasibility study, next to the determination of the optimal tracer dose.
Familial adenomatous polyposis (FAP) leads to adenomas and eventual adenocarcinomas in colon and less frequently, duodenum. Chemopreventive strategies have been studied in FAP patients to delay the development of adenomas and cancers. The non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitor have shown the regression of colorectal and duodenal adenomas in FAP patients. However, these drugs showed gastrointestinal damage and cardiovascular risks, and new preventive strategies are needed. Metformin, a biguanide, which is widely used for treating diabetes mellitus, has recently been suggested to have a suppressive effect on tumorigenesis via mTOR-inhibiting pathway, and have no significant safety issues in long term use. The investigators devised a double-blind randomized controlled trial to evaluate the effect of metformin on polyps of colorectum and duodenum in non-diabetic FAP patients.
This study is being done to evaluate single incision laparoscopic surgery (SILS) for colorectal diseases, compared to multi-port laparoscopic surgery. This study is also intended to standardize the SILS technique for colorectal diseases
The purpose of this registry is to collect information about patients in which a pouch has been created to improve in the future the quality of the surgery of the pouch.
The purpose of this randomized, double-blind, Phase III trial is to determine if the combination of eflornithine plus sulindac is superior to sulindac or eflornithine as single agents in delaying time to the first occurrence of any FAP-related event. This includes: 1) FAP related disease progression indicating the need for excisional intervention involving the colon, rectum, pouch, duodenum and/or 2) clinically important events which includes progression to more advanced duodenal polyposis, cancer or death.
The purpose of this study is to assess the long-term outcome in a cohort of Gardner-Syndrome patients receiving prophylaxis and treatment for intestinal and non-intestinal tumors.
Total proctocolectomy with ileal pouch anal anastomosis is the first choice surgical operation for management of ulcerative colitis and familial adenomatous polyposis. The addition of diverting ileostomy may reduce septic complications. In this randomized study the investigators compare two groups of patients with stapled ileoanal pouch one of them had diverting ileostomy and in the other this step is omitted.
