Systemic effects of treatment with mTOR inhibitors in tuberous sclerosis complex: a comprehensive review.

Tuberous sclerosis complex (TSC) is a genetic multisystem disorder associated with constitutive overactivation of the mammalian target of rapamycin (mTOR) pathway and characterized by development of benign tumours in various organs. mTOR inhibitors have proven to be effective in the targeted therapy of certain TSC-associated pathologies such as subependymal giant cell astrocytomas (SEGAs) and renal angiomyolipomas (AMLs). Accumulating experimental and clinical data suggest that mTOR inhibitors might have a systemic, disease-modifying influence on affected individuals. This systematic review provides an analysis of available clinical data concerning systemic effect of mTOR inhibitors and the influence of mTOR inhibition on different manifestations of TSC in individual patients.
