There is also an increased awareness that the clinical phenotype and cancer risk varies by specific mismatch repair mutation, which in turn has implications on surveillance strategies for patients. As Lynch syndrome is an inherited condition there is a 50:50 chance of passing on the condition through generations, so whole families can be devastated by cancer. Results: For MSH6 mutation carriers, the estimated cumulative risks to ages 70 and 80 years, respectively, were as follows: for colorectal cancer, 22% (95% confidence interval [CI] = 14% to 32%) and 44% (95% CI = 28% to 62%) for men and 10% (95% CI = 5% to 17%) and 20% (95% CI = 11% to 35%) for women; for endometrial cancer, 26% (95% CI = However, " HBOC " can be misleading because mutations in these two genes can also increase the risk for Any medical information published on this website is not intended as a substitute for informed medical advice and you should not take any action before consulting with a healthcare professional.

ASCO recommends that tumor testing for Lynch syndrome be performed in all people diagnosed with colorectal cancer and recent guidelines recommend tumor testing for all endometrial cancers as well. There is not always clear evidence about how much lifestyle factors affect cancer risk in people with LS. MicroRNA is a type of RNA that plays a role in regulating the expression of genes in DNA. Results: Questionnaires were sent to 192 patients with Lynch syndrome who underwent surgery for colorectal cancer. The researchers believe that chronic low grade inflammation due to obesity and insulin resistance may be responsible for the microRNA changes.
