ROMERO-ROJAS, Alfredo  y  MELO-URIBE, Mario Alexander. Implementation of the Bethesda system for cytology reporting of thyroid fine needle aspirates with histological follow-up: experience in a cancer treatment center. rev.colomb.cancerol. [online]. 2014, vol.18, n.1, pp.3-7. ISSN 0123-9015.

Objective: To determine the frequency of the final histological diagnosis in the follow-up of cytology results of thyroid fine needle aspirates implemented using the Bethesda system (BS). Methods: A cross-sectional study was conducted comparing the cytology results of thyroid fine needle aspirates implemented with the BS, and the final histopathology result in patients with thyroid gland lesions, who were seen in the Colombia National Cancerology Institute during the years 2010 to 2012. Results: A review was made of the cytopathology and histopathology reports of 104 patients with thyroid nodules. The mean age of the patients was 51.9 years. The results of the cytopathology by BS categories were: 37.5% category V, 30.8% category VI, 15.4% category IV, 6.7% categories I and II, and 2.9% category III. Papillary carcinoma was the most frequent histopathology diagnosis of all the cases, with 76%, followed by goiter with 6.7%. In the comparative analysis, the cytology categories IV, V and VI, 89.8% of the cases had a malignant lesion in the final histology report, and 77% of those of category II (benign) had the same result in the final histopathology diagnosis. Conclusions: The cytology of thyroid fine needle aspirates interpreted using the BS in the National Institute of Cancerology is of high diagnostic quality in the detection of thyroid malignancy when compared with the final histopathology diagnosis.
