Genetic testing for polyposis: practical and ethical aspects: The three autosomal dominant inherited polyposis syndromes, familial adenomatous polyposis, juvenile polyposis, and Peutz-Jeghers polyposis predispose to colorectal cancer as does hereditary non-polyposis colorectal cancer syndrome. Uncovering the genetic background of these four cancer traits provides the possibility for genetic testing of the family members of an affected patient. Before testing identification of the underlying family specific pathogenic mutation is mandatory. This is possible in about 60% to 95% of families. Endoscopic surveillance can be safely discontinued in mutation negative family members and surveillance or prophylactic surgery can be targeted to mutation positive members alone - http://gut.bmjjournals.com/cgi/content/full/52/suppl_2/ii19

IGF2 loss of imprinting: a potential heritable risk factor for colorectal cancer: This study provides support for the novel concept that abnormal insulin-like growth factor 2 (IGF2) imprinting in peripheral blood leukocytes (PBL) may provide the basis for an epigenetic blood test to screen individuals early in life to identify those who are highly susceptible to developing colorectal cancer (CRC) - http://www.gastrojournal.org/article/PIIS0016508504002987/fulltext

Hereditary Colorectal Cancer: Review: Patients with a familial risk — those who have two or more first- or second-degree relatives (or both) with colorectal cancer — make up approximately 20 percent of all patients with colorectal cancer, whereas approximately 5 to 10 percent of the total annual burden of colorectal cancer is mendelian in nature — that is, it is inherited in an autosomal dominant manner. In this review the authors have focused on the two major forms of hereditary colorectal cancer, familial adenomatous polyposis and hereditary nonpolyposis colorectal cancer - http://content.nejm.org/cgi/content/full/348/10/919

Current and evolving strategies for colorectal cancer screening: In this study the literature and clinical practice guidelines are reviewed, with an emphasis on advances of the last 10 years and evolving screening methods. The authors note that colonoscopy has come to be used for screening in persons at average risk for colorectal cancer because of the comparative ineffectiveness of other methods, although these methods continue to be recommended. Virtual colonoscopy and fecal DNA testing are emerging technologies with promise to be more effective than fecal occult blood testing or sigmoidoscopy in selecting those persons who should undergo colonoscopy - http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=12794617

Molecular stool screening for colorectal cancer: Mass screening for colorectal cancer reduces mortality. Recent recognition of the adenoma-carcinoma sequence and pathophysiological studies of colonic epithelium have enabled tumour markers to be used in the screening setting. Non-invasive molecular stool testing has now been shown to have a high sensitivity and specificity, but larger clinical trials are required - http://www3.interscience.wiley.com/cgi-bin/fulltext/109083289/HTMLSTART
