NICE recommends wider use of tests to detect cancer-causing genetic condition

NICE has published diagnostics guidance recommending that everyone who is diagnosed with colorectal cancer should be tested for an inherited genetic condition called Lynch syndrome (LS).

CONCLUSIONS: Universal tumour testing strategies for guiding germline genetic testing of people with incident CRC for LS in Australia are likely to be cost-effective compared with no testing. Universal germline gene panel testing would not currently be cost-effective. PMID: 31595523 [PubMed - as supplied by publisher]

ConclusionsResults of the Idylla ™ MSI Assay were highly concordant with results of routine tests and lower failure rates were observed. Further advantages are the lack of need for matched normal tissue, the low dependence on pre-analytical conditions, the simplified workflow, the short turnaround times, the automated result inte rpretation, and the very limited hands-on work.Editorial acknowledgementTeams involved in the MSI, Idylla MSI Assay, Colon Rectal Cancer, Multicenter Study.Legal entity responsible for the studyIrblleida.FundingBiocartis.DisclosureX.

Abstract About 5% of colorectal cancer (CRC) cases occurred in the context of an underlying hereditary predisposition syndrome. Lynch syndrome is the main causes of hereditary CRC but is also associated with a higher risk of other cancers (such as endometrial cancer and ovarian cancer). It is the consequence of constitutional mutation in a MisMatch Repair (MMR) gene, involved in DNA repair: MLH1, MSH2, MSH6 or PMS2; or of the EPCAM gene (MSH2 promotor). If a mutation predisposing to Lynch Syndrome is identified in an individual, special monitoring should be initiated, adapted to estimated cancer risk. Clinical cri...

ConclusionFurther studies should be conducted to provide new insights about survival of colorectal carcinoma in Lynch syndrome, as well as the therapeutic alternatives for this neoplasia.ResumoIntroduçãoO carcinoma colorretal é a terceira neoplasia mais prevalente no mundo, bem como a segunda causa de morte por câncer. A maioria destas neoplasias são esporádicas, devidas a mutações somáticas, mas cerca de 15% são hereditárias como a síndrome de Lynch ou Hereditary Nonpolyposis Colorectal Cancer (HNPCC). Apesar de ser a mesma neoplasia, esta ...

Dye-based pancolonic chromoendoscopy is recommended for colorectal cancer surveillance in patients with Lynch syndrome. However, there is scarce evidence to support its superiority to high-definition white-light endoscopy. We performed a prospective study assess whether in the hands of high detecting colonoscopists, high-definition, white-light endoscopy is non-inferior to pancolonic chromoendoscopy for detection of adenomas in patients with Lynch syndrome.

Establishing criteria for assessment allows for the identification of individuals who are carriers of pathogenic genetic variants. The NCC...

This study aimed to investigate the spectrum of germ-line mutations in Russian LS patients. LS-related mismatch repair (MMR) genes were analyzed in 16 patients, who were forwarded to genetic testing due to strong clinical features of LS and had high-level microsatellite instability (MSI-H) in the tumor (n = 14) or unknown MSI status (n = 2). In addition, 672 consecutive colorectal cancer (CRC) cases were screened for family history; 15 patients were younger than 50 years and reported 2 or more instances of LS-related cancers in 1st- or 2nd-degree relatives. Seven of these cases demonstrated MSI-H and th...
