Abstract:
The functional loss of the mismatch repair system is related to the occurrence of colorectal cancer. Some colorectal cancers have mismatch repair defects, however, the methylation of the MLH1 promoter cannot be detected, and germline mutations of the mismatch repair genes are not detected. Because this part of the group is very similar to Lynch syndrome, it is named Lynch-like syndrome. Lynch-like syndrome has certain genetic characteristics, but the pathogenesis has not been fully understood; and it cannot be simply classified as sporadic colorectal cancer or Lynch syndrome, and there is a lack of genetic knowledge and monitoring standards of these patients. This article introduces the progress of Lynch-like syndrome.
