[Experience with a high-dose therapy concept in metastatic differentiated thyroid cancer]

Abstract

Three patients with pulmonary metastases from differentiated thyroid carcinoma were treated with radioiodine. As a first treatment either 1.85 GBq (50 mCi) or 3.7 GBq (100 mCi) were given followed by doses of 11.1 GBq (300 mCi) 131I. In one patient the pulmonary metastases disappeared completely, the two other patients showed a significant regression. In one patient possibly radiation-induced pancytopenic changes appeared after the third and fourth radioiodine treatment, in the other two patients side-effects were not seen.
