Abstract
OBJECTIVE: To evaluate the smear adequacy of both thyroid and breast fine needle aspiration (FNA) by reviewing FNA slides at one medical center in Taiwan.
STUDY DESIGN: A total of 503 thyroid and 316 breast FNA smears from April 1 to June 30, 2004 were selected and reviewed. A pathologist performed the FNA slide review to determine the smear adequacy according to the criteria of Kini and Layfield. Among the cases studied, those who were operated on before June 30, 2005 were further investigated to analyze the pathology results after operations compared with prior FNA diagnoses. The sensitivity and specificity of FNA examination were then calculated.
RESULTS: A high percentage of inadequate smears were observed for both thyroid (82.8%) and breast (69.5%) FNAs, all presenting a false negative diagnosis in the inadequacy group. The smear adequacy rates were significantly different between different specialties. We also found that the higher the frequency of aspirations performed, the higher was the adequacy rate of aspirated smears. Moreover, the greater the number of slides prepared by aspirators, the higher was the smear adequacy rate.
CONCLUSION: Many specialties and doctors are involved in thyroid FNA aspiration. A low number of slides prepared and passes taken during FNA aspiration, as well as infrequent and unskilled aspirators, are important factors for the low smear adequacy. Formal training for all aspirators and guidelines for FNA procedures are recommended in the hospital studied.
