Thyroid cancer is the most common endocrine malignancy. Lymph node metastasis is common in patients with papillary thyroid carcinoma, especially in children and young adults and can be sued during admission. Aim of this study is to evaluate the incidence of thyroid cancer metastases to cervical lymph nodes in patients referred to an ear, nose and throat specialist Imam Khomeini in Iran in 2013 to 2014. All patients who were hospitalized and undergoing thyroid surgery at a medical center of Imam Khomeini Hospital (RA) in Ahvaz from early in April 2013 to end of March 2016 and the thyroid cancer diagnosis was confirmed according to the pathology samples for them. Pathology samples were collected through existing records in the archives of Imam Khomeini Hospital (RA) of Ahvaz Jundishapur University. The information contained in the records includes age, gender, types of thyroid cancer, history of thyroidectomy keeping with the nodules, presence of metastasis and its sites on the basis of information contained in the records. analysis was performed by using SPSS 16 software. the frequency related to papillary cancer with 23 patients (59%) and medullary cancer with 6 patients (15.4%) and follicular and anaplastic cancers each one with 3 patients (7.7%). 20 patients (51.3%) were diagnosed with metastatic thyroid cancer. Most metastasis was related to lymph metastasis in 11 patients (28.2%) and the lowest metastasis was lung metastasis in 2 patients (5.1%) and 19 patients (48.7%) had no metastasis and 7 patients had metastasis to several organs. 24 patients (61.4 %) had thyroid nodules. 9 patients (23.1%) cold nodules with calcification and 10 patients (25.6%) cold nodules without calcification and 1 patient (2.6%) with hot nodules have been reported. From the present study, it is concluded that papillary cancer had the highest frequency and it is suggested to conduct specific study in this field and also carry out a study on pathologic assessment of lymph nodes isolated for checking the hidden metastases.
