TG and metastatic malignant neoplasm in the lymph nodes: In our population, the main predictors for short-term DTC recurrence were extrathyroidal extension, tumoral infiltration of surgical margins, the presence of lymph node metastases at diagnosis, and high stimulated Tg levels in the context of RAI, while medium- and long-term DTC recurrence were independently predicted by one-year tumor relapse.
