[Quality assurance of fine-needle aspiration cytology of the organized mammography screening].
The National Public Health Program has established the organized mammography screening in Hungary.


OBJECTIVE
The aim of our study was to determine the quality assurance of breast aspiration cytology.


METHODS
Cytology results were rated to 5 categories (C1, C2, C3, C4 and C5). All cytology reports were compared with the final histology diagnosis.


RESULTS
1361 women had aspiration cytology diagnosis performed from a total of 47718 mammography non-negative lesions. There were 805 (59.1%) benign and 187 (13.7%) malignant alterations. Sensitivity was 91%, specificity 88%, positive predictive value 96.6% and negative predictive value turned to be 71% (p<0.001).


CONCLUSIONS
The auditing values of fine needle aspiration cytology in our laboratory meet, or in certain aspects exceed the proposed minimum threshold values.
