M. C. Cummings, B. A. Waters and P. K. O’Rourke Breast fine needle aspiration cytology: a review of current practice in AustralasiaAims: To investigate breast fine needle aspiration (FNA) cytology in Australasia, in terms of laboratory demographics, specimens received and quality control (QC). Methods: A questionnaire was sent to all laboratories enrolled in the FNA module of the Royal College of Pathologists of Australasia Cytopathology Quality Assurance Program (QAP), requesting information about specimens received in a 3‐month period in 2001 and in 2008. Results: Responses were received from 81/180 laboratories in 2001 and from 94/200 in 2008. The mean number of cases per 3 months was 137 in 2001 and 141 in 2008 and for the 42 laboratories responding on both occasions, the mean number of cases declined from 191 to 149 ( P = 0.001). The mean percentage of malignant cases was 11.7% in 2001 and 10.5% in 2008 and the mean percentages of unsatisfactory rates were 21.7% and 25.2%, respectively; 43.2% of laboratories in 2001 and 40.4% in 2008 reported fewer than 50 cases for the 3‐month period. The unsatisfactory rate was inversely proportional to the number of cases received. Most QC (69.1% in 2001, 71.3% in 2008) was carried out by correlation with any later histology. With no histology available, 35.8% of laboratories in 2001 and 48.9% in 2008 did no further follow‐up. Follow‐up of all diagnostic categories increased from 30.9% in 2001 to 44% in 2008. Conclusions: Breast FNA cytology is still actively undertaken in Australasia, but numbers have declined. Unsatisfactory rates have reached the Australian recommended upper limit and are inversely proportional to the total number of cases received. Overall QC measures are unchanged and consideration of a review of breast FNA guidelines is suggested.
