Objective  To summarize the diagnosis and treatment of Hashimoto thyroiditis (HT) coexistence with
thyroid cancer (TC).
Methods  One hundred and eighty-four patients with HT treated in The Affiliated Hospital of Guiyang Medical College from Jan. 2008 to Dec. 2011 were collected, and clinical data of 32 patients with TC of them were analyzed retrospectively.
Results  Thirty two patients combined with TC of the 184 patients with HT, and the incidence rate was 17.4%. All of the 32 patients were treated surgically according to the principle of surgery treatment for TC. Of the 32 cases of HT coexistence with TC, 15 patients were diagnosed by preoperative fine needle aspiration cytology (FNAC), and the sensitivity of FNAC was 46.9% (15/32). Twenty seven patients were diagnosed by intraop-erative frozen section pathological examination, and the sensitivity of it was 84.4% (27/32), which was significantly higher than those of FNAC (χ2=7.563,P=0.004). Thirty patients were diagnosed as papillary thyroid carcinoma (PTC), and 2 patients were diagnosed as follicular thyroid carcinoma (FTC) by postoperative paraffin section pathological exam-ination and (or) immunohistochemistry, respectively. All patients were treated with levothyroxine (L-T4) after operation,and 5 patients were treatment with 131I therapy in addition. One patient suffered convulsion, and 2 patients suffered mild hoarsenessthere after operation. Only 29 patients were followed up for 3-49 months (average 35 months), and during the followed up, there were no tumor recurrence, metastasis, and death.
Conclusions  The rate of preoperative diagnosis of HT coexistence with TC is low, and auxiliary examinations play an important role in diagnosis and guiding treatment. Surgery is the preferred treatment, but auxiliary therapies after surgery are indispensable too.
