We studied 19 patients who had undergone operation for differentiated carcinoma of isthmus of the thyroid in Shinshu University Hospital from 1967 to 1986. Regarding the operations, total thyroidectomy was performed in 6 cases, subtotal thyroidectomy in 8 cases, lobectomy in one case and isthmectomy in 4 cases. In 12 cases, lymph node dissection was carried out. Among these 12 cases, 6 cases (50%) had evidence of metastasis. Intraglandular metastasis was fotind in 3 cases. There were no relationship between tumor size and nodal metastasis.
From these results, we do not think that total thyroidectomy is indicated in the case of differentiated carcinoma of isthmus of the thyroid. In conclusion, subtotal thyroidectomy with bilateral modified radical neck dissection is sufficient as the operative procedure for differentiated carcinoma of isthmus of the thyroid.
