Surveillance in Lynch syndrome.

Review article
Mecklin JP, et al. Fam Cancer. 2005.


The major aim of surveillance in Lynch syndrome is to diagnose malignant or premalignant lesions at the asymptomatic stage by regular checkups, particularly in the large bowel. Therefore, screening for colorectal adenomas and carcinomas by regular colonoscopies is the main topic of the present review. However, it should be remembered, that primary prevention - whether through the use of chemoprevention or the promotion of a healthy life-style may form a significant part of such surveillance in the future. Observational studies indicate that the adenoma carcinoma sequence is the main pathway in the development of colorectal cancer in Lynch syndrome. A colonoscopy every 1-3 years starting at age 20 to 25 years and the removal of observed adenomas is recommended for individuals known to have Lynch syndrome associated mutations. The incidence of colorectal cancer in family branches screened this way is lower than that in past unscreened generations. The screening of other malignancies associated with Lynch syndrome is more complex. Screening for endometrial cancer has recommended previously, but no benefits have been shown in recent studies. The value of screening for other extracolonic cancers remains also uncertain.
