HERRERA, Francisco et al. Utility of the fine needle aspiration cytology in the diagnosis of follicular neoplasms of the thyroid gland at Hospital Universitario del Caribe, Cartagena, Colombia. rev. colomb. cir. [online]. 2015, vol.30, n.1, pp.12-17. ISSN 2011-7582.

Introduction: This study evaluates retrospectively the performance of cytology obtained by fine needle aspiration in the diagnosis of follicular neoplasms of the thyroid gland. Methods: A review of medical records of patients with diagnostic impression of thyroid nodule over a period of seven years from 2007 to 2013 was completed, in those patients in which a fine needle aspiration cytology prior to a surgical approach was performed. The cytological diagnosis was compared with pathologic study to determine the performance parameters. Results:The study population included 149 patients. The following performance parameters of the fine needle aspiration cytology were determined in the diagnosis of follicular neoplasms: sensitivity, 54.5%; specificity, 92.9%; positive predictive value, 57.1%; negative predictive value, 92.2%; accurately diagnosed, 87.2%; false negatives and false positives 6.9%, 6.1% Conclusion: Fine needle aspiration cytology has a low sensitivity in the diagnosis of follicular neoplasms of the thyroid gland due to the cytologically similarity presented by this group of lesions with goiters with adenomatous changes.

Keywords : thyroid nodule; carcinoma; papillary; follicularr; biopsy; fine-needle; cytology; diagnosis; sensitivity and specificity.
