CITOLOGÍA POR PUNCIÓN ASPIRACIÓN CON AGUJA FINA TIROIDEA Y SU CORRELACIÓN DIAGNÓSTICA CON EL RESULTADO HISTOPATOLÓGICO DEFINITIVO EN LOS PACIENTES SOMETIDOS A TIROIDECTOMÍA UNIDAD DE CIRUGÍA GENERAL HOSPITAL DR. TEODORO MALDONADO CARBO - GUAYAQUIL, 2015 - 2016

Abstract

Background: Thyroid conditions are common in Ecuador, and goiter was an endemic disease in the last century. Diagnosis has been improved with diagnostic techniques, but identification of malignant thyroid nodules remains a challenge for pathologists, endocrinologists, and surgeons. Objective: To establish the diagnostic relationship between fine needle aspiration cytology and the definitive histopathological outcome of patients undergoing thyroidectomy at Teodoro Maldonado Carbo Hospital. Methods: A descriptive, retrospective study of 101 patients with nodular thyroid disease who underwent surgery, who underwent a cytological study by PAAF and 15 BIO were performed. Results: 85% were female and 14.85% male. The PAAF report was negative for malignancy in 65 patients (64.35%) and positive 36 (35.64%); False negatives 25 (24.76%) The effectiveness indicators identified were: sensitivity (30.60%), specificity (100%), accuracy (72.20%), VVP and NPV (100.00 and 72.20 %, respectively). In patients undergoing BIO the sensitivity 77,80%, specificity 83.8%, PPV 94.9% accuracy 80.0%. It is concluded that thyroid PAAF is a low sensitivity and high specificity method for the diagnosis of thyroid cancer and BIO has a higher sensitivity than PAFF.
