Long-Term Survival and Low Effective Cumulative Radioiodine Doses to Achieve Remission in Patients With 131Iodine-Avid Lung Metastasis From Differentiated Thyroid Cancer

Abstract

Lung metastasis showed a slow progression with a high long-term overall survival. The presence of synchronous lung metastasis, the absence of nodules larger than 1 cm, and the lack of uptake of FDG were predictive factors for an early response to treatment with RAI cumulative doses lower than 600 mCi 131I.
