ABSTRACT
Objective:To analyze the clinical characteristics of Hashimoto's disease complicated with papillary thyroid carcinoma and research surgical treatment and Hashimoto's disease's effect to papillary thyroid carcinoma. Method:Three hundred and twelve cases of papillary thyroid carcinoma were retrospectively reviewed. Among 70 cases of papillary thyroid carcinoma associated Hashimoto's disease (the observation group), 242 cases of single papillary thyroid carcinoma (the control group). Result:The observation group compared with the control group, there was a significant difference in gender, tumor size, thyroid antibody level and the lymph node metastasis, with statistical significance (P<0.05). Conclusion:Hashimoto's disease is a kind of protective factors of thyroid papillary carcinoma, Hashimoto's disease with coexistent papillary thyroid carcinoma is smaller in tumor diameter and have lower lymph node metastasis. Surgery takes the original operation primary radical and central lymph node dissection, try to avoid the preventive side neck lymph node dissection.
