When the MMR genes were identified as the underlying genetic etiology of Lynch syndrome in the early 1990s, little was known about the optimal means of diagnosis of families with Lynch syndrome or prevention of Lynch-associated cancers, and the malignancies that developed were treated in exactly the same way as their sporadic counterparts. The efficacy of immune-checkpoint inhibitors in LS-associated tumors has been shown to be similar to that in sporadic dMMR tumors. INTRODUCTION.
