Predictive value of antithyroglobulin antibody on recurrence or metastasis following ablation in differentiated thyroid carcinoma

Objective To investigate the value of serum thyroglobulin(Tg)and antithyroglobulin antibody(Tg Ab)in differentiated thyroid carcinoma complicated with Hashimoto’s thyroiditis after thyroid ablation.Methods Serum Tg and Tg Ab levels and the status of illness in 154differentiated thyroid carcinoma patients with coexistent Hashimoto’s thyroiditis and confirmed pathology after surgery followed by remnant ablation were performed during three years follow up.Tg and Tg Ab levels were assessed
