[Oral TRH stimulation in patients with thyroid carcinoma]
Abstract:
In patients with differentiated thyroid carcinoma high serum TSH-levels enhance 131 J-uptake in thyroid remnant and/or metastases. An effective increase of TSH could be achieved by oral administration of thyrotropin releasing hormone (TRH) even after a short T4/T3-withdrawal period so that we recommend a TRH-stimulation in all patients before a diagnostic or therapeutic 131 J-application. Adverse reactions to TRH are infrequent and usually short timed so that in contrast to TSH-stimulation--TRH can be given to outpatients without any risk.
