About

Exogenous injection of recombinant human thyroid stimulating hormone (rhTSH) can elevate TSH in the short term (2 days) to meet the requirements of diagnostic 131I SPECT/CT whole-body scans. Antiangiogenic tyrosine kinase inhibitors (TKI) couuld alter the uptake of radioactive 131I in locally advanced or metastatic differentiated thyroid cancer. rhTSH can help to perform the diagnostic 131I SPECT/CT whole-body scans before and after the TKI usage. rhTSH can reduce the risk of tumor progression caused by thyroid hormone withdrawal period and the side effects of hypothyroidism also caused by thyroid hormone withdrawal, and clarify the 131I uptake change after TKI treatment.

Researchers believe that the presence of any condition may harm the subjects or prevent them from meeting or fulfilling the study requirements.
