Circulating metabolome landscape in Lynch syndrome
This study aims to characterize the circulating metabolome of Lynch syndrome carriers, shedding light on the energy metabolism status in this cancer predisposition syndrome.This study consists of a three-group cross-sectional analysis to compare the circulating metabolome of cancer-free Lynch syndrome carriers, sporadic colorectal cancer (CRC) patients, and healthy non-carrier controls. We detected elevated levels of circulating cholesterol, lipids, and lipoproteins in LS carriers. Furthermore, we unveiled that Lynch syndrome carriers and CRC patients displayed similar alterations compared to healthy non-carriers in circul...

Loss of symbiotic and increase of virulent bacteria through microbial networks in Lynch syndrome colon carcinogenesis
ConclusionEnhanced fecal virulent/symbiotic bacteria ratios influence bacterial network structures. As an early event in colon carcinogenesis, these ratios can be used to identify asymptomatic LS individual with a higher risk of CRC. (Source: Frontiers in Oncology)

Cancers, Vol. 16, Pages 671: Real-World Data on Institutional Implementation of Screening for Mismatch Repair Deficiency and Lynch Syndrome in Endometrial Cancer Patients
Franziska Siegenthaler Lynch syndrome is an inherited tumor syndrome caused by a pathogenic germline variant in DNA mismatch repair genes. As the leading cause of hereditary endometrial cancer, international guidelines recommend universal screening in women with endometrial cancer. However, testing for Lynch syndrome is not yet well established in clinical practice. The aim of this study was to evaluate adherence to our Lynch syndrome screening algorithm. A retrospective, single-center cohort study was conducted of all endometrial cancer patients undergoing surgical treatment at the Bern University Hospital, Switzerlan...

Sporadic Prostate Cancer in a Patient With Lynch Syndrome
A man in his 60s with Lynch syndrome and a history of colorectal adenocarcinoma and cholangiocarcinoma was found to have a prostatic lesion in the left posterior lateral peripheral zone on magnetic resonance imaging. His serum prostate-specific antigen level was 3.1 ng/mL. (Source: Mayo Clinic Proceedings)

Low prevalence of gastric intestinal metaplasia and Helicobacter pylori on surveillance upper endoscopy in Lynch syndrome
AbstractLynch syndrome (LS) increases the risk of numerous different cancers including gastric cancer. While some current guidelines recommend empiric gastric biopsies be performed during upper gastrointestinal cancer surveillance in Lynch syndrome (LS), the yield of these biopsies and the prevalence of gastric intestinal metaplasia (GIM) andHelicobacter pylori (HP) in LS remains unknown. Herein we analyze 165 consecutive individuals with LS who underwent upper endoscopic surveillance with biopsies of the gastric antrum and body being performed universally in all individuals. Of the study cohort, 6.7% of universally biopsi...

High amount of fertility reducing tumors and procedures, but no evidence for premature ovarian failure in female Lynch syndrome patients
AbstractLynch syndrome (LS; HNPCC) patients carry heterozygous pathogenic germline variants in mismatch repair (MMR) genes, which have also been shown to play an important role in meiosis. Therefore, it was hypothesized, that LS might be associated with a higher risk for premature ovarian failure (POF) or earlier menopause. Data on medical gynaecological history, cancer diagnoses and therapy were collected from 167 female LS patients and compared to a population-based control cohort. There was no difference between the age of menopause in patients compared to controls and no evidence for a higher risk of POF in LS patients...

Mismatch repair deficiency in multifocal gastric epithelial neoplasia and non-dysplastic glands: Harbinger of Lynch syndrome in an autoimmune gastritis patient
A 66-year-old woman, with a first-degree family history of gastric cancer (GC), a personal history of endometrial intraepithelial neoplasia, and a recent diagnosis of GC, associated with a previously undiagnosed autoimmune gastritis (AIG), was referred to our Clinic. AIG diagnosis was made according the internationally-recognised Sydney-Houston criteria (i.e., atrophy of the corpus/fundus mucosa which spares the antrum in the absence of active Helicobacter pylori infection). Parietal cell antibodies were positive. (Source: Digestive and Liver Disease)
