PERFIL EPIDEMIOLÓGICO E HISTOPATOLÓGICO DOS PACIENTES SUBMETIDOS À TIREOIDECTOMIA EM UM HOSPITAL UNIVERSITÁRIO: ESTUDO RETROSPECTIVO DE 11 ANOS

Abstract

Introduction: American data show that about 30% of thyroidectomies are performed due to a diagnosis of cancer. With regard to the Brazilian scenario, information regarding the profile of thyroidectomized patients is scarce.

Objectives: To carry out an epidemiological survey and catalog the histopathological diagnosis of patients submitted to thyroidectomy in 11 years.

Methods: Retrospective observational study with collections through the medical records system with the variables sex, age, surgical approach, characteristics of the lesions and anatomopathological report.

Results: During the 11 years, 298 thyroidectomies were performed, 52.34% in patients aged over 60 years and 86.91% female. When classifying the diseases into papillary carcinoma, follicular carcinoma, goiter, colloid nodule, lymphocytic thyroiditis, adenoma and others, it was found that of these, 22.27% were classified as malignant, mostly papillary carcinoma. Surgical intervention in 82% of cases was total thyroidectomy. Papillary carcinomas were the most common histological type present in 89.77%.

Conclusion: The main epidemiological data found in this population were: predominance of women; general average age above 60 years in 53.34%; incidence of malignant lesions in 22.27%, highly predominant papillary type with metastases in 9.56%; total thyroidectomy in 82.88%; and nodules in different sizes, but larger than 2 cm in 64.52%.
