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.
