dc.description.abstractObjetivo Evaluar el rendimiento diagnóstico del ACAF de tiroides al comparar con el Gold Standard, la patología de la tiroidectomía y describir en ella la frecuencia de tiroiditis de Hashimoto en los especímenes de patología. Métodos Se realizó un estudio descriptivo retrospectivo de una muestra de tiroidectomías realizadas por el equipo de cirugía de cabeza y cuello del Hospital Universitario Nacional de Colombia desde 2016 a 2021. Se obtuvo el ACAF de nódulo tiroideo prequirúrgico y la última ecografía prequirúrgica de los pacientes llevados a estos procedimientos en quienes se sospechaba malignidad, para realizar una descripción demográfica y búsqueda de prevalencia de cáncer de tiroides y de tiroiditis de Hashimoto. Finalmente se realizó un estudio de rendimiento diagnóstico del ACAF prequirúrgico al compararlo con el espécimen quirúrgico. Resultados De 465 especímenes de tiroidectomía se encontraron 322 casos de cáncer (ca) papilar, 5 foliculares, 3 medulares, 2 oncocíticos y 4 malignidades diferentes a cáncer de tiroides (paraganglioma, en clasificación y metástasis de ca escamocelular). Entre los hallazgos ecográficos prequirúrgicos más predominantes se encontraron los nódulos hipoecoicos (n=191), con calcificaciones (n=230), vascularizados (n=155), con márgenes irregulares (n=128), TIRADS 4 (n=124), mayores de 1 cm (n=186). Se encontró asociación estadística con malignidad en las primeras 4 características. No se encontró una asociación significativa entre Tiroiditis de Hashimoto y cáncer de tiroides y las dos patologías coexistieron en 16% (n=75) de las tiroidectomías. El rendimiento diagnóstico del ACAF para la detección del cáncer de tiroides tuvo una sensibilidad del 83%, una especificidad del 27%, VPP 75%, VPN 37% combinando Beth V y VI y en solitario se encontró la sensibilidad más alta en el Bethesda V (73%). Conclusión Se encontraron frecuencias de malignidad más altas y un rendimiento diagnóstico inferior al esperado del ACAF, lo que probablemente se atribuye a los criterios de inclusión y a la alta sospecha de malignidad para llevar a cabo las tiroidectomías. Existen dificultades en la selección del nódulo y en la interpretación de la citología prequirúrgica, lo que puede explicar el alto número de especímenes quirúrgicos que resultaron en malignidad.

dc.description.abstractObjective: To evaluate the diagnostic performance of the thyroid nodule FNAB compared to the Gold Standard, the thyroidectomy, and describe the frequency of Hashimoto Thyroiditis in the surgical specimens. Methods This is a retrospective descriptive study of a sample of thyroidectomies performed by the head and neck surgery team of the National University Hospital of Colombia since 2016 to 2021. The pre-surgical thyroid nodule FNAB was obtained, and the last thyroid ultrasonography of patients taken to thyroidectomy by suspicion of underlying malignancy, to make a demographic description and search for the prevalence of thyroid cancer and Hashimoto thyroiditis. Finally, a diagnostic performance study was conducted comparing the pre-surgical FNAB to the surgical specimen. Results From 465 surgical specimens, 322 cases of papillary thyroid cancer were found, as well as 5 follicular, 3 medullary, 2 oncocytic and 4 malignancies different from thyroid cancer (paraganglioma, non-classified neoplasia and squamous carcinoma metastases). Within the most predominant ultrasonographic findings of the nodules: hypoechoic (n=191), with calcifications (n=230), vascularized (n=155), irregular margins (n=128), TIRADS 4 (n=124), bigger than 1 cm (n=186). Statistically significant association with malignancy was found in the first 4 characteristics. There was no significant association found between Hashimoto thyroiditis and thyroid cancer and the two pathologies coexisted in 16% (n=75) of the thyroidectomies. The diagnostic performance of the FNAB for the detection of thyroid cancer had a sensitivity of 83%, a specificity of 27%, PPV 75%, NPV 37% by combining Bethesda V and VI and in solitary the highest sensitivity was found on Bethesda V (73%). Conclusion Higher malignancy frequencies and an inferior-than-expected diagnostic performance of the FNAB were found, which is probably attributed to the inclusion criteria and the high malignancy suspicion that led to thyroidectomy. There are also difficulties in the selection of the nodule and in the interpretation of the pre-surgical cytology, which can explain the high number of surgical specimens that resulted in malignancy.eng
