Abstract
Objectives : Despite its importance, no clear diagnostic standard exists for differentiating diagnostic breast cytology categories. To remedy this, we propose ABCD scoring—atypia , bipolarity loss, cellularity , and discohesion .
Study Design : Subjects were 942 of 2192 breast cytology diagnoses we conducted that were adequate for cytological diagnosis and enabled histological confirmation by biopsy or surgery. Of thease , 210 were benign and 732 malignant.
Results : Under ABCD scoring , 319 cases were 4 (+) and all were malignant (100%), 201 were 3 (+) and 198 malignant (99%), 96 were 2 (+) and 86 malignant (90%), 102 were 1 (+) and 55 malignant (54%), and 224 were 0 (+) and 74 malignant (33%). ABCD scoring of (+) as 2, (±) as 1 , and (−) as 0, 319 cases were 8 point and all were malignant (100%), 195 were 7 point and 191 malignant (98%), 86 were 6 point and 79 malignant (92%), 77 were 5 point and 57 malignant (74%), 49 were 4 point and 24 malignant (49%), 43 were 3 point and 18 malignant (21%), 39 were 2 point and 11 malignant (28%), 63 were 1 point and 13 malignant (21%), and 71 were 0 point and 20 malignant (28%).
Conclusion : Cases of 4 (+) or 8 under ABCD scoring were all malignant, indicationg a considerable correlation between ACBD score and frequency of malignancy, making ABCD scoring useful in evaluating diagnostic categories and conducting breast cytology safety diagnosis.
