Purpose:Germ-line mutations in the exonuclease domains of POLE and POLD1 have been recently associated with polyposis and colorectal cancer (CRC) predisposition. Here, we aimed to gain a better understanding of the phenotypic characteristics of this syndrome to establish specific criteria for POLE and POLD1 mutation screening and to help define the clinical(More)
Germline mutations in DNA polymerase ɛ (POLE) and δ (POLD1) have been recently identified in families with multiple colorectal adenomas and colorectal cancer (CRC). All reported cases carried POLE c.1270C>G (p.Leu424Val) or POLD1 c.1433G>A (p.Ser478Asn) mutations. Due to the scarcity of cases reported so far, an accurate clinical phenotype has not been(More)
UNLABELLED Upper gastrointestinal variceal bleeding is one of the most serious complications in patients with chronic liver disease. The aim of this trial is to identify in hospital mortality predictors in this illness. MATERIAL AND METHODS 106 hospitalizations due to this disease from October 2001 to April 2006 in cohort design. In hospital mortality was(More)
Aberrant telomere length measured in blood has been associated with increased risk of several cancer types. In the field of hereditary non-polyposis colorectal cancer (CRC), and more particularly in Lynch syndrome, caused by germline mutations in the mismatch repair (MMR) genes, we recently found that cancer-affected MMR gene mutation carriers had shorter(More)
BACKGROUND The knowledge of mortality predictors and evolutive variables linked with in-hospital death can help us to optimize corrective procedures. OBJECTIVES To identify independent predictors of in-hospital mortality and survival, and independent evolutive links with death in patients with generalized secondary peritonitis (GSP). METHODS Two hundred(More)
Ma et al comprehensively assessed the association of previously reported genetic variants with colorectal cancer (CRC) risk. The meta-analyses revealed strong evidence for association with rare MUTYH variants, even when excluding cases with MUTYH-associated polyposis. An article by Nieuwenhuis et al accurately defined the phenotypical features of(More)
Identification of genes associated with hereditary cancers facilitates management of patients with family histories of cancer. We performed exome sequencing of DNA from 3 individuals from a family with colorectal cancer who met the Amsterdam criteria for risk of hereditary nonpolyposis colorectal cancer. These individuals had mismatch repair-proficient(More)
BACKGROUND & AIMS Although there is a genetic predisposition to colorectal cancer (CRC), few of the genes that affect risk have been identified. We performed whole-exome sequence analysis of individuals in a high-risk family without mutations in genes previously associated with CRC risk to identify variants associated with inherited CRC. METHODS We(More)
BACKGROUND Hereditary non-polyposis colorectal cancer (CRC) without mismatch repair (MMR) defects occurs in almost half of high-risk CRC families, but its genetic cause(s) is(are) still unknown. We aimed to identify unique molecular features that differentiate hereditary from sporadic MMR-proficient colorectal tumours. METHODS Genomic alterations in 16(More)
