Hashimoto's thyroiditis accompanying with thyroid cancer:98 cases / 中华内分泌外科杂志

ABSTRACT

Objective To discuss the clinical characteristics of Hashimoto's thyroiditis accompanying with thyroid cancer. Methods Clinical data of 98 cases Hashimoto's thyroiditis accompanying with thyroid cancer were retrospectively reviewed. Results 2 cases underwent lateral thyroid lobectomy and isthmus resection. 58 cases underwent bilateral thyroid lobectomy. 35 cases underwent central lymph node dissection, with 15 cases of lymph node positive. 3 cases underwent modified radical dissection of cervical lymph nodes and all of them were proved to be lymph node positive. Metastasis rate is 25.0% and 52. 2% respectively for tumors whose diameter was less than 1 cm and greater than 1 cm. The difference has no statistic significance. Conclusions Hashimoto's thyroiditis usually accompany with thyroid papillary carcinoma and cervical lymph node metastasis can occur even if it's microcarcinoma. Lymph node metastasis rate increases with increasement of the tumor's diameter. Total thyroidectomy should be performed for Hashimoto's thyroiditis concomitant with thyroid cancer. And if necessary,lymph node dissection should be extended to the central region and lateral neck area.
