The use of recombinant human TSH in a patient with metastatic follicular carcinoma and insufficient endogenous TSH production.
We present a case of a patient suffering from metastatic differentiated thyroid carcinoma (DTC) and insufficient endogenous TSH production suspicious of secondary hypothyroidism. The use of recombinant human TSH (rhTSH) enabled us to administer a therapeutic activity of radioactive iodine (RAI) under maximal TSH-stimulation, achieving a marked decrease in thyroglobulin accompanied by a clinical improvement.
