Familial adenomatous polyposis is characterized by over 100 colorectal adenomas in the colorectum. The disease equally affects both sexes, with an incidence estimated at 1.14025-1.8300. The disease is premature in people with familial adenomatous polyposis. Patients suffering from familial adenomatous polyposis have a range of extra-intestinal diseases such as papillae, gastric, small intestine...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 colorectal cancer is classified in to three forms: sporadic (70-75%), familial (20-25%) and hereditary (5-10%). hereditary colorectal cancer syndromes classified into two different subtypes: polyposis and non polyposis. familial adenomatous polyposis (fap; omim #175100) is the most common polyposis syndrome, account for <1...

desmoids tumors, characterized by monoclonal proliferation of myofibroblasts, could occur in 5-10% of patients with familial adenomatous polyposis (fap) as an extra-colonic manifestation of the disease. fap can develop when there is a germ-line mutation in the adenomatous polyposis coli gene. although mild or attenuated fap may follow mutations in 5΄ extreme of the gene, it is more likely that ...

Genetic Analysis of D-Loop Region Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study

introduction: due to the whole network of polyposis registers worldwide and early prophylactic treatment, survival of familial adenomatosis (fap) patients is improved. extracolonic manifestations are remarkable feature of fap. two extracolonic manifestations (duodenal adenomatosis, leading duodenal cancer and desmoid tumours) play a very important role in the reasons of death in polyposis popul...

Familial adenomatous polyposis is an archetypal disease illustrating the genetic basis of human cancer. The adenomatous polyposis coli gene functions as a tumor suppressor with hundreds of known mutations that result in a defective adenomatous polyposis coli protein. In addition to the certain fate of colon cancer without colectomy, patients with familial adenomatous polyposis are also at incre...

     Familial adenomatous polyposis (FAP) is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the Adenomatous Polyposis Coli (APC) gene on chromosome 5q21. Patients with FAP suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. FAP has also...

Fundic gland polyps (FGPs) are the most common type of gastric polyps (up to 50%). They are found in up to 0.8-1.9 % of the general population, and in 40-84 % of the patients suffering from familial polyposis syndromes. They might be sporadic or associated to polyposis syndromes. When the former, they should be considered exclusively benign lesions, and possibly related to the chronic use of pr...

Desmoid tumors are one of the most common extracolonic manifestations of the familial adenomatous polyposis. However, other soft tissue tumors are seen rarely in patients with familial adenomatous polyposis, including gastrointestinal stromal tumor. There is only one case reported in the literature. We describe a 29-year-old female who developed ileal malignant gastrointestinal stromal tumor 15...

PURPOSE Restorative proctocolectomy is the procedure of choice for patients undergoing proctocolectomy for familial adenomatous polyposis or ulcerative colitis. This meta-analysis was designed to identify differences in adverse events and functional outcomes between these two groups. METHODS Studies published between 1986 and 2003 that compared outcomes between patients with familial adenomat...
