Treatment of Medullary Ca of thyroid with lymph node metastasis: (A) Sub total thyroidectomy + Radioiodine + TSH supression, (B) Subtotal thyroidectomy + Radiotherapy, (C) Total thyroidectomy + Radioiodine, (D) Total thyroidectomy + Radiotherapy
Answer is D. .In medullary carcinoma thyroid , total thyroidectomy is treatment of choice. Radiotherapy can be considered in unresectable cases or after complete surgical resection in few cases.
