Histopathological distribution of thyroid cancers: A retrospective analysis of 570 patients

Thyroid Cancer and Subtypes

Abstract

Aim: Thyroid cancers are the most commonly encountered endocrine system malignancies.  The incidence continues to rise worldwide. Our aim in this study is to investigate the frequency and histopathological subtypes of thyroid cancer in our clinic.

Methods: The present study was conducted with 3614 patients who were followed up in our endocrinology and general surgery clinic and operated with the diagnosis of multinodular and/or nodular goiter between 2015 and 2021. The histopathological types and information of patients diagnosed with thyroid cancer were obtained retrospectively from the pathology reports. Among the patients included in the study, a total of 570 people who were reported to have thyroid cancer due to histopathology were included in the study.

Results: The data of a total of 3614 biopsy reports were examined for the study. Among these patients, 570 (421 females, 149 males) were operated and whose pathology reports were accessed were included in the study. The mean age of the patients was 49.12±10.4 years. As a result of the operations, malign postoperative tissue histopathology was 98.9% (n=564), and uncertain malignancy potential was reported to be 1.0% (n=6). In our study, the histopathological distribution of thyroid cancers was as follows; thyroid papillary cancer 89.4% (n=510), follicular cancer 7.3% (n=42), medullary cancer 2.1% (n=12), and malignancy potential uncertain 1.0% (n=6).

Conclusion: The results of our study suggest that thyroid cancers are more common in women in our country, in parallel with the similar rates reported in the literature, with the increase worldwide.
