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...

Familial adenomatous polyposis (FAP) is the most common inherited polyposis syndrome. Almost all patients with FAP will develop colorectal cancer if their FAP is not identified and treated at an early stage. Although there are many reports about polypoid lesions and colorectal cancers in FAP patients, little information is available concerning depressed lesions in FAP patients. Several reports ...

Staging provides essential prognostic information relevant for choosing adequate therapy and should also identify patients with resectable distant metastases. Preoperative staging consists of clinical examination, blood counts, liver and renal function tests, carcino-embryonic antigen (CEA), chest X-ray or CT scan, CT scan of the abdomen, and colonoscopy of the entire large bowel, i.e. with pos...

Familial adenomatous polyposis ia an autosomal dominant disorder that is responsible for 0.5% of all colorectal cancer. Patients will develop hundreds to thousands of colonic polyp in their second decades of life. The life time risk of developing colorectal cancer is 100% at the median age of 39 years. Extra intestinal manifestations are rare and mostly are benign. Family history of colorectal ...

Background Hereditary non-polyposis colorectal cancer (HNPCC) is a hereditary cancer syndrome in which confirmed carriers of a gene mutation are at high risk for colorectal (CRC) and extracolonic cancers. The purpose of the current study was to develop a greater understanding of the factors influencing the decision-making of confirmed HNPCC carriers post-genetic testing about screening and dise...

There are several molecular pathways of colorectal cancer. At least four separate pathways of colorectal cancer exist: (A) adenomatous polyposis coli pathway in which B cateni-T cell factor-MYC factors are implicated (APC-B catenin-Tcf-MYC) in adenoma carcinoma sequence, (B) hereditary non-polyposis colorectal cancer pathway (HNPCC) characterized by loss of DNA mismatch repair by inherited or a...

Familial adenomatous polyposis (FAP) is an inherited disorder that represents the most common gastrointestinal polyposis syndrome. Germline mutations in the APC gene were initially identified as responsible for FAP, and later, several studies have also implicated the MUTYH gene as responsible for this disease, usually referred to as MUTYH-associated polyposis (MAP). FAP and MAP are characterize...

BACKGROUND AND AIMS Although diet and lifestyle are associated with the development of colorectal malignancies, the only clearly identified aetiological factors in colorectal cancer are inheritance (hereditary non-polyposis colorectal cancer (HNPCC) and familial polyposis), inflammatory bowel diseases, papillomavirus, and acquired immunodeficiency syndrome (AIDS). Our aim was to determine what ...

The majority of colorectal cancer (CRC) cases are sporadic, with hereditary factors contributing to approximately 35% of CRC cases. Less than 5% of CRC is associated with a known genetic syndrome. Although adenomatous polyposis syndromes, hamartomatous polyposis syndromes, and those previously classified as non-polyposis CRC syndromes are quite rare, it is important for clinicians to know the c...
