Introduction: Sensitivity and specificity of thyroid cytology in our series of thyroidectomies were evaluated.
Material and methods: A retrospective, multicentre study of 1567 thyroidectomies performed in the eight hospitals of Castilla La Mancha (Spain) during the years 20102013.
Results: The cytological results were benign in 37.6% of cases, malignant or suspicious of malignancy in 17.3% (10 and 7.3% respectively). In 4.1% of cases the cytology was atypical or indeterminate and in 12.5% follicular proliferation/follicular lesion. There were 8% non-diagnostic cytologies. In patients whose prequirúgical FNA was nondiagnostic, 20.6% had a carcinoma. Overall, 25.6% of patients had thyroid carcinoma. The sensitivity and specificity of suspicion of malignancy or malignant thyroid cytology for the diagnosis of malignancy was 75.8 and 90.3% respectively. There were 3.5% false positive and 4.5% false negative results.
Conclusions: Thyroid cytology is the diagnostic technique of choice for the study of thyroid nodule. The results in terms of sensitivity, specificity and nondiagnostic cytology in our series are acceptable.
