Características clínicas, ultrasonográficas y anatomopatológicas de pacientes operados por sospecha de malignidad tiroidea

摘要

Introduction: thyroid carcinoma is characterized by slow progression and high recovery percentage. Objective: to describe the clinical, ultrasonographic and anatomopathological characteristics of patients operated on for thyroid malignancy. Methods: retrospective and descriptive study for which the primary data were collected from the medical histories of patients who met the inclusion criteria. These criteria comprised surgery for suspected thyroid malignancy, age over 18 years, and complete demographic, clinical, ultrasonographic and anatomopathological data and registration at the hospital. Frequency distribution tables were drawn up. The ratio comparison test was applied to describe the statistical significance of the studied variables with respect to the thyroid malignancy. Results: in the group of patients with thyroid malignancy, 81.8 % were females, 39.4 % aged 41 to 50 years. The ultrasonographic test showed that 75.8 % of them had a thyroid nodule area greater than 10 mm, 53.3 % presented solitary nodule morphology whereas the result of the fine needle aspiration cytology was thyroid carcinoma. The histological classification yielded papillary carcinoma in 91 % of patients. Conclusions: the papillary carcinoma was the most common, particularly in females aged 41 to 50 years who had over 1 cm nodules.
