Impact of moderate vs stringent TSH suppression on survival in advanced differentiated thyroid carcinoma

Abstract
To assess (i) the influence of Thyrotropin (TSH) suppression at a level of 0·1 mU/l, are associated with an impaired prognosis. There is, however, no prognostic benefit from suppressing TSH to levels lower than 0·1 mU/l. On the contrary, an improvement in prognosis might be achieved by keeping FT3 levels as low as possible.
