[Clinical research on 2228 cases of thyroid gland tumors]

To discuss outcome of thyroid tumor patients treated with surgery.

Total number of patients was 2228. These patients of thyroid tumors from 1992-2004 (2072 cases of benign thyroid diseases and 156 cases of thyroid carcinoma) were recruited. The clinical and follow-up datum were retrospective analyzed.

(1) Benign thyroid tumors with near-total thyroidectomy including 1761 thyroid adenoma, 207 nodular goiter and 104 Hashimoto thyroiditis, the incidence of recurrent laryngeal nerve paralysis was 0.2%, 55 cases (2.6%) received secondary surgery. All the patients have no hypocalcemia or hemorrhage after operation. (2) Eighty-one cases of papillary carcinoma of the thyroid ( > 1 cm) and 60 cases of microcarcinoma. Unilateral thyroidectomy, contralateral near-total thyroidectomy and ipsilateral modified neck dissection were performed in unilateral papillary carcinoma of thyroid. Among the 9 cases of follicular carcinoma of thyroid, 7 were performed of near-total thyroidectomy without neck dissection, others were the same as papillary carcinoma. Bilateral total thyroidectomy and bilateral modified neck dissection were performed in 2 cases of the medullary thyroid cancer and 1 case of the undifferentiated thyroid cancer. By direct method the 5-year survival was 95.5% (64/67), and by Kaplan-Meier method, it was 98.0%. The treatment of microcarcinoma are multiple. There is no relapse or metastases in 60 cases of papillary thyroid microcarcinoma. The 5-year survival was 100.0%, 1 cases occurred recurrent laryngeal nerve paralysis in thyroid cancer. No hypocalcemia or hemorrhage. Eight case relapsed in 156 cases of thyroid carcinoma,3 cases died.

The correct surgical management for the patients with thyroid tumor should benefit for the prognosis and reduce the complications and the recurrence of the operation.
