Ileoanal pouch anastomosis is the procedure of choice for patients with drug refractory ulcerative colitis, indeterminate colitis and familial adenomatous polyposis (FAP). In selected patient groups this procedure is a treatment option for patients with Crohn's disease, hereditary nonpolyposis colorectal cancer (HNPCC), synchronous colorectal cancer and for severe colorectal constipation refractory to conservative drug treatment. The pouch procedure provides the opportunity to avoid a permanent ileostomy. The majority of surgeons prefer the ileal J‑pouch as the construction is the easiest to perform and complications and dysfunction rates are low...

BACKGROUND: Muir-Torre syndrome (MTS) is characterized by sebaceous neoplasms with internal malignancies and regarded as a variant of hereditary nonpolyposis colorectal cancer (HNPCC). Pathogenic variations of MTS have been identified in the MSH2, MLH1, and MSH6 genes, with the majority of variations located in MSH2. OBJECTIVES: To present an MTS patient who was the only individual with skin malignancies within a cancer-prone pedigree and to show the usefulness of RNA-based genetic analysis in the investigation of MTS...

BACKGROUND: Individuals with hereditary non-polyposis colorectal cancer (HNPCC) have a high risk of colorectal cancer (CRC). The benefits of colonic surveillance in Lynch syndrome and Amsterdam-positive (familial CRC type X familial colorectal cancer type X (FCCTX)) families are clear; only the interval between colonoscopies is debated. The potential benefits for families not fulfilling the Amsterdam criteria are uncertain. The aim of this study was to compare the outcome of colonic surveillance in different hereditary subgroups and to evaluate the surveillance programmes...

Carcinomas are rare tumors of the adolescent-young adult (AYA) with a different spectrum from those of adults. The most common sites outside of the thyroid is the nasopharynx, salivary gland, colon-rectum and ovaries. If nasopharyngeal carcinoma or salivary gland tumors are good prognosis, others are more reserved prognosis, such as digestive carcinomas, gynecological or midline. The revelation modes are non-specific and depend on the location: mass, tumor syndrome, pain, impaired general condition. The unusual of pediatric carcinomas led to propose a systematic oncogenetic exploration...

OBJECTIVES: Roughly half of hereditary nonpolyposis colorectal cancer (HNPCC) cases are Lynch syndrome and exhibit germ-line mutations in DNA mismatch repair (MMR) genes; the other half are familial colorectal cancer (CRC) type X (FCCTX) and are MMR proficient. About 70% of Lynch syndrome tumors have germ-line MLH1 or MSH2 mutations. The clinical presentation, histopathological features, and carcinogenesis of FCCTX resemble those of sporadic MMR-proficient colorectal tumors. It is of interest to obtain biomarkers that distinguish FCCTX from sporadic microsatellite stable (MSS) CRC, to develop preventive strategies...

BACKGROUND: Colorectal cancer (CRC) remains a major health burden with an incidence of 1.3 million new cases worldwide and a mortality of almost 8.5%. It is the 2nd most common cancer in women (1st breast carcinoma) and 3rd most common in men (1st lung carcinoma, 2nd prostate carcinoma). CRC alongside breast, lung, prostate and stomach cancer is in the top five most common cancers in men and women worldwide. There are still more than 50% of CRC patients diagnosed with advanced disease (stage III and IV) in the Czech Republic...

About half of hereditary non-polyposis colorectal cancers (HNPCCs) fulfilling the Amsterdam criteria (AC) do not display evidence of mismatch repair defects, and the difference between microsatellite-stable (MSS) and microsatellite-unstable HNPCC remains poorly understood. The study was to compare overall copy number variation (CNV) and loss of heterozygosity (LOH) of the entire genome in HNPCCs with MSS and microsatellite-instability (MSI) using the Cytoscan HD Array. This was a study carried out in samples from 20 patients with MSS HNPCC and four patients with MSI HNPCC from the Fudan University Shanghai Cancer Center (China)...

Muir-Torre syndrome (MTS) is a rare autosomal dominant inherited genodermatosis that is considered to be a phenotypic subtype of hereditary nonpolyposis colorectal cancer (HNPCC), commonly referred to as Lynch syndrome. We describe the clinical course of a 57-year-old female patient with MTS. She has a confirmed HMSH2 mutation. Recently she presented with two nodular lesions. Histologic examination confirmed these lesions to be sebaceous neoplasms. The patient has a history of endometrial and colorectal adenocarcinoma as well as several nonspecific sebaceous lesions throughout her life...

Lynch syndrome or hereditary nonpolyposis colorectal cancer (HNPCC) is the most common form of hereditary colorectal cancers. It increases cancer susceptibility, the risk of colorectal cancer in first-degree, endometrial cancer in women, and to a lesser extent, other cancers (ovarian, small bowel, stomach, urinary tract and hepatobiliary). Thus, the cumulative risk of developing colorectal cancer or endometrial cancer at the age of 80 years rises to 20 and 40% respectively. These cancers are characterized by a positive family history, their occurrence at an early age, and by the development of metachronous cancers in the same individual...

In the past two decades, significant advances have been made in our understanding of colorectal (CRC) tumors with DNA mismatch (MMR) repair deficiency. The knowledge from molecular and genetic alterations in a variety of clinical conditions has refined the disease terminology and classification. Hereditary non-polyposis colorectal cancer (HNPCC) encompasses a spectrum of conditions that have significant phenotypic overlapping that makes clinical diagnosis a challenging task. Distinguishing among the HNPCC disorders is clinically important, as the approach to surveillance for patients and their at-risk family members differs according to risks for colonic and extracolonic cancer associated with each syndrome...

There is a number of drugs demonstrating specific activity towards hereditary cancers. For example, tumors in BRCA1/2 mutation carriers usually arise via somatic inactivation of the remaining BRCA allele, which makes them particularly sensitive to platinum-based drugs, PARP inhibitors (PARPi), mitomycin C, liposomal doxorubicin, etc. There are several molecular assays for BRCA-ness, which permit to reveal BRCA-like phenocopies among sporadic tumors and thus extend clinical indications for the use of BRCA-specific therapies...

INTRODUCTION: Lynch syndrome is known by healthcare providers mainly for patients with colorectal cancer. Awareness of other associated tumors, such as endometrial or ovarian cancer, is low. This study aimed to analyze the prevalence of Lynch syndrome in unselected patients with endometrial or ovarian cancer. In addition, the willingness of patients and family members to undergo germline mutation testing was investigated. METHODS: The medical records of all patients diagnosed with endometrial or ovarian cancer at the Department of Gynecology and Obsterics, University Hospital Dresden, between 1998 and 2012, were screened for a family history of HNPCC-associated cancer...

Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant disorder characterized by the early onset of colorectal cancer (CRC) linked to germline defects in Mismatch Repair (MMR) genes. We present here, the first molecular study of the correlation between CRC and mutations occurring in these genes performed in twenty-one unrelated Algerian families. The presence of germline mutations in MMR genes, MLH1, MSH2 and MSH6 genes was tested by sequencing all exons plus adjacent intronic sequences and Multiplex ligand-dependent probe amplification (MLPA) for testing large genomic rearrangements...

Lynch syndrome, previously called hereditary non-polyposis colorectal cancer (HNPCC), is a major mortality threat. It is an autosomal dominant disease which is caused by a germline mutation in the DNA mismatch repair (MMR), especially in patients aged up to 50 years. Such mutation more frequently occurs in the hMSH2 gene (38-40%) and less frequently in the hMSH6 gene (14-16%). These mutations, when associated with the patient's lifestyle, may reveal a considerable variability in the disease manifestations, such as the degrees of penetrance and clinical aggressiveness...

BACKGROUND: Prostate cancer (PC) is a major health concern for men worldwide, with an estimated lifetime risk of ~14 %. A recent comprehensive analysis of mutational processes revealed ageing and mismatch repair as the only altered processes in PC. We wish to test if a cohort of men with inherited risk of mismatch repair defect through BRCA1/2 or Lynch Syndrome mutations represents a target population for prostate cancer testing. METHODS: Fifty-eight men (aged 40-69 years) from families with a history of BRCA1/2 or HNPCC/Lynch mutations were invited to take part...

Lynch syndrome (formerly known as hereditary non-polyposis colorectal cancer) is the most com-mon hereditary colorectal cancer syndrome. The syndrome is caused by a germline mutation of one of the mismatch repair (MMR) genes responsible for DNA replication error repair. Impaired function of the proteins encoded by these genes leads to microsatellite instability (MSI), which is associated with increased incidence of neoplasms: mainly colorectal cancer. According to recent estimates, up to 5% of all colorectal cancers are associated with Lynch syndrome...

Hereditary nonpolyposis colorectal cancer (HNPCC) is caused by functional defects in mismatch repair (MMR) genes, including mutL homolog 1 (MLH1) and mutS homolog 2 (MSH2). This study aimed to assess whether the mRNA expression of MLH1 in peripheral blood could be used as a biomarkers for the diagnosis of HNPCC. The mRNA level of MLH1 was determined in 19 HNPCC families (46 members) using real-time quantitative polymerase chain reaction (qPCR). The mRNA levels of MLH1 in HNPCC were significantly lower than controls (P < 0...
