Clinical and radiological features and excision diagnosis in patients with no core biopsy (166 cases) or normal core biopsy diagnosis (four cases)
| Radiological or clinical feature | Excision specimen diagnosis | χ2 with Yates’ correctiona | |
|---|---|---|---|
| Fibroadenoma, tubular adenoma, hamartoma | Phyllodes tumour | ||
| Size up to 30mm | 71 | 3 | χ2=0.0002 |
| >30mm | 91 | 5 | p=0.99 |
| Size up to 40mm | 129 | 5 | χ2=0.5 |
| >40mm | 33 | 3 | p=0.47 |
| Age up to 25 years | 128 | 7 | χ2=0.02 |
| >25 years | 34 | 1 | p=0.90 |
| Radiological growth | 40 | 3 | χ2=0.2 |
| No growth | 122 | 5 | p=0.69 |
| Growth >15%/month | 15 | 3 | χ2=3.8 |
| <15%/month | 147 | 5 | p=0.05 |
| Growth >10%/month | 20 | 3 | χ2=2.3 |
| <10%/month | 142 | 5 | p=0.13 |
| Radiological suspicion | 0 | 0 | |
| No suspicion | 162 | 8 | |
aStatistical comparison of the frequency of these features in phyllodes tumours compared with other fibroepithelial lesions was made with chi squared with Yates’ correction.
