Table 1.

Demonstrates the sensitivity of fine-needle aspiration cytology (FNAC) and core biopsy in the diagnosis of benign, borderline and malignant phyllodes tumours (PTs)

Classification	FNAC sensitivity	Core biopsy sensitivity	Imaging sensitivity	Labelled as PT
Benign	2 of 6 (33%)	20 of 28 (71%)	34 of 34 (100%)	3 of 31 (10%)
Borderline	1 of 1 (100%)	14 of 15 (93%)	16 of 16 (100%)	8 of 15 (53%)
Malignant	1 of 1 (100%)	3 of 3 (100%)	3 of 4 (75%)	1 of 4 (25%)
Overall	4 of 8 (50%)	37 of 46 (80%)	53 of 54 (98%)	12 of 50 (24%)

The table also demonstrates the imaging sensitivity for lesions called U3 and above; however, the final column shows the percentage of PT correctly identified by the reporting radiologist indicative of a much lower true sensitivity in predicting a PT over fibroadenomas in the advance of biopsy.
