Objective:

to evaluate the precision of the different cut-off points of the BAAF Bethesda score in comparison with the histopathological study for the diagnosis of thyroid pathology.

Methods:

quantitative, observational, cross-sectional, analytical study for the evaluation of diagnostic tests. It included 293 patients with thyroid disease suggestive of cancer, who attended the General Surgery Service of Hospital Obrero No. 2 of the National Health Fund, during the period 2019-2022. Non-randomized convenience sampling was performed that included all available patients.

Results:

the correlation between the two variables studied was confirmed, that is, between the Bethesda score and the histopathological study report, with a confidence interval (CI) of 95%.

Conclusions:

it is demonstrated that the BAAF has high specificity in the diagnosis of thyroid cancer with Bethesda reports V and VI, on the contrary, minor Bethesda reports II, III, and IV, rule out the diagnosis.
