Abstract

Introduction: Thyroid cancer is the most common malignant endocrine system. It accounts for less than 1% of malignant neoplasms in humans and accounts for the highest number of deaths caused by endocrine gland cancer. The objective of this research was to evaluate the demographic characteristics and paraclinical results of patients with differentiated thyroid cancer in several hospitals in Urmia. Methodology: In this cross-sectional descriptive study, all patients with differentiated thyroid cancers confirmed by pathological findings were included in a 13-year period of study (2000-2013). Demographic characteristics (age, gender, clinical complaints of patients, type of cancer and stage of disease were derived from medical records of patients) and analyzed by SPSS20 software. Results: Out of 112 patients studied, 87 cases (77.7%) were papillary, 20 (17.85%) were follicular, 3 cases (2.7%) were modular and 2 cases (78. 1%) were anaplastic in terms of tumor type. The pathological results indicated that 50 cases (44.65%) were Stage I, 28 cases (25%) were Stage II, 11 cases (9.82%) were Stage II, and 23 cases (20.5%) were Stage IV. In addition, negative autoantibody was reported in 91 cases (81.25%), and positive autoantibody was reported in 21 cases (18.75%). Conclusion: In our research, papillary thyroid cancer, as most of other similar studies, had the highest prevalence and it was more common in females. Given its lymphatic dissemination, its metastasis can be prevented with timely admission to physician and the survival rate of the patients can be increased by early treatment.
