Correlación ecográfica – citológica de pacientes con diagnóstico de nódulo tiroideo del Hospital Isidro Ayora Loja durante el periodo 2015 - 2019

The TIRADS (Thyroid Image Reporting and Data System) classification proposed by the American College of Radiology shows 6 ecographic categories, as the score is higher it carries a greater risk of malignancy, verifying with the Bethesda cytological diagnosis, which is stratified into 6 diagnostic categories and each one of them contain a risk of malignancy from 0-3% to 99%. A proportionally positive correlation is described; however, the existing correlation in patients in our environment is not known. A retrospective correlational study was performed between ecographic and cytological results of patients with thyroid nodule at the Isidro Ayora Loja hospital during the period 2015 - 2019, with the purpose of characterize the patients and establish the level of correlation of both variables. From 487 patients (19 men and 468 women), the 46% were benign nodules, the 28.1% were thyroid neoplasia (Bethesda IV, V VI) and the 25.9% Bethesda I and III; with higher prevalence in the age group from 40 to 64 years. The risk of malignancy found in TIRADS 2, 3, 4ª, 4b, 4c and 5 was 13.3%, 11%, 29.7%, 52.9%, 72.2% and 76.6% respectively, the level of correlation was positive, weak to moderate (Rho index 0.419; reference range: -1.0 negative correlation and +1 positive correlation),with a sensitivity of 78.8%, also specificity of 71.40%, PPV of 63, 3% and especially NPV of 84.7%. Conclusion: there is a good correlation between TIRADS and Bethesda, allowing the reduction of unnecessary biopsies and an adequate management of the patient with a thyroid nodule.
