CONCLUSIONS: This study confirms the effectiveness of tumor testing to identify LS among patients with CRC. Although IHC and MSI analysis were similarly effective, IHC could be a better strategy for LS identification as it is less expensive and more feasible.

Guidelines recommend that all colorectal tumors be assessed for mismatch repair deficiency, which could increase identification of patients with Lynch syndrome. This is of particular importance for minority populations, in whom hereditary syndromes are under diagnosed. We compared rates and outcomes of testing all tumor samples (universal testing) collected from a racially and ethnically diverse population for features of Lynch syndrome.

DiscussionThe aim of this systematic review is to provide a robust estimate of the prevalence of Lynch syndrome in women with endometrial cancer. This will enable resource allocation and decision-making regarding the appropriateness of screening all women, or certain women, with endometrial cancer for Lynch syndrome. Such a policy could enable the earlier diagnosis of Lynch syndrome in women and, through the application of colorectal cancer surveillance, improve their survival outcomes.Systematic review registrationThis systematic review has been registered on PROSPERO (refCRD42017081707).

Abstract Adrenocortical carcinoma (ACC), particularly when occurring during childhood, has been a traditional component of the tumor spectrum of Li-Fraumeni syndrome. Recent research has defined a significant risk increase of ACC with other familial cancer syndromes, such as Lynch syndrome and multiple endocrine neoplasia. ACC patients can serve as index patients for a new family diagnosis of a hereditary syndrome, allowing for further family cascade genetic testing, impacting the care and surveillance for patients and at risk family members. Individuals carrying pathogenic genetic variants can embark on a regular...

In this study, we employed the combination of germline testing and tumor mutational assessment to help discern the clinical relevance of VUS and guide immunotherapeutic decisions. KEY POINTS: A clinical dilemma arises when genomic testing yields variants of uncertain significance (VUS).Germline VUS were identified in two patients with gastrointestinal malignancies, but only one patient had a second-hit mutation in a mismatch repair gene leading to mismatch repair deficiency that conferred response to immunotherapy.The combination of germline testing along with tumor mutational assessment can help discern the clinical ...

CONCLUSION: We describe the Nottingham Lynch Syndrome Test (N_LyST). This is a quick, simple and cheap method for screening for Lynch syndrome. PMID: 29472252 [PubMed - indexed for MEDLINE]

Patients with Lynch syndrome are at high risk for developing colorectal cancer (CRC). Regular colonoscopic surveillance is recommended, but there is no international consensus on the appropriate interval. We investigated whether shorter intervals are associated with lower CRC incidence and detection at earlier stages by comparing the surveillance policies in Germany, which evaluates patients by colonoscopy annually, in the Netherlands (patients evaluated at 1 –2-year intervals), and Finland (patients evaluated at 2–3-year intervals).

It is important to identify individuals with Lynch syndrome because surveillance programs can reduce their morbidity and mortality from colorectal cancer (CRC). We assessed the diagnostic yield of immunohistochemistry to detect Lynch syndrome in patients with advanced and multiple adenomas within our national CRC screening program.
