Microsatellite instability in endometrial cancer 30

Justine Varinot.
Abstract
The microsatellite instability reflects genetic instability that can be sought in tumors, using two methods, immunohistochemistry and molecular biology. Currently in France, a systematic evaluation of microsatellites is recommended in any endometrial cancer from diagnosis. The interest of this evaluation is threefold: diagnostic, prognostic and therapeutic. The presence of microsatellite instability in endometrial cancer allows to detect Lynch syndrome, a hereditary cancer predisposition syndrome, in some patients. The microsatellite status is essential for establishing the molecular classification of endometrial cancers, a classification which has a well-established prognostic value, and finally it determines the eligibility for immunotherapy.
