Prevalence of benign and malignant tumors in thyroidectomy specimens

Introduction: The most common type of endocrine malignancy is thyroid cancer (TC). TC is the 7th, 14th, and 11th most common cancer in women, men, and both sexes, respectively. Objectives: The aim of this research was to establish the frequency of benign and malignant tumors in thyroid surgery specimens performed in Al-Zahra hospital in Isfahan from 2011 to 2017. Patients and Methods: This is a retrospective descriptive cross-sectional study. 1345 patients who underwent thyroid surgery were enrolled using census sampling. Data were analyzed using SPSS software (IBM statistics for windows, version 16) using descriptive statistics, mean, standard deviation, frequency, chi-square, and ANOVA. A significance level of less than 0.05 was analyzed. Results: Of 1345 participants, 237 (17.6%) were males, and 1108 (82.4%) were females. The mean age of benign patients was 46.48, malignant 39.31, and healthy patients for 37.50 years. Since the level of significance is less than 0.05, there is a significant relationship between the mean age of patients and the frequency of thyroid surgery specimens. The most prevalent benign and malignant thyroid tumors were goiter (76.8%) and papillary carcinoma (92.6%), respectively. Conclusion: The results showed that there was a significant relationship between age, gender, and benign and malignant type. Also, the most prevalent benign and malignant thyroid tumors were goiter and papillary, respectively
