Differentiated Thyroid Carcinoma Presenting With Distant Metastasis at Initial Diagnosis

Abstract

Our study showed that DTC patients presenting with initial DM appear to have relatively favorable outcomes compared with DTC patients who developed DM after initial treatment. Complete local control may be the most important prognostic indicator in all DM patients. Metastatic lesion iodine avidity had a significant impact on both OS and DSS in patients developing DM after initial treatment, but significantly influenced only DSS in patients presenting with initial DM.
