Lynch syndrome is one of the most common hereditary cancer predisposition syndromes, which is caused by germline pathogenic variants in mismatch repair genes. It is associated with increased risks of colorectal cancer, endometrial cancer and various other types of cancer. With the rapid development in economy, medicine and genetic tests technology in recent decades, China had achieved significant advancements in the screening, diagnosis and treatment of Lynch syndrome. However, there are still a lot of challenges remaining unresolved. The major challenges include inconsistent access to genetic tests and counseling, regional disparities in healthcare quality, and limited implementation of clinical guidelines. This review will focus on the Chinese current status in the screening of Lynch syndrome, cancer surveillance, preventive measures, patients' willingness to take genetic tests and share genetic information, insurance coverage of medical cost, and national collaboration. At the end, we also summarize the major current research themes in Lynch syndrome in China.
