Accuracy of cytotechnologist evaluation of specimen adequacy and screening interpretation of malignancy in fine-needle aspiration of the liver.

Objective: To evaluate the performance of cytotechnologists in assessing the adequacy and accuracy of the preliminary diagnosis for fine-needle aspirates of the liver.

Study Design: We retrospectively analyzed 10 years of data and found 589 cases of ultrasound-guided fine-needle aspiration (FNA) of the liver with on-site evaluation of adequacy (OSEA). All the OSEA were performed by the cytopathologist because OSEA of liver FNA is not performed by cytotechnologists at our institution at present.
