Germline mutations of the LKB1 gene are associated with Peutz-Jeghers syndrome, which is characterized by mucocutaneous pigmentation and gastrointestinal hamartoma with an increased risk of cancer development. To investigate the role of LKB1 in vivo, we have recently constructed Lkb1 gene knockout mice. Because of Lkb1 gene haploinsufficiency, the heterozygous Lkb1 mice develop gastrointestinal...
AIM To evaluate the utility of double-balloon enteroscopy for small-bowel disease. DESIGN A prospective study of 50 consecutive enteroscopies performed from December 2004 to July 2005 to analyze diagnoses and treatments. PATIENTS 44 patients (33 had undergone a previous capsule endoscopy) with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspe...
Gastrointestinal (GI) tract cancers that arise due to genetic mutations affect a large number of individuals worldwide. Even though many of the GI tract cancers arise sporadically, few of these GI tract cancers harboring a hereditary predisposition are now recognized and well characterized. These include Cowden syndrome, MUTYH-associated polyposis, hereditary pancreatic cancer, Lynch syndrome, ...
Intestinal polyposis syndromes, such as familial adenomatous polyposis (FAP) and Cowden's syndrome, are often associated with extraintestinal manifestations, and while many of these manifestations are benign, malignant extraintestinal manifestations, such as differentiated thyroid cancers, do occur. Although differentiated thyroid cancers (ie, papillary and follicular thyroid carcinomas) are as...
