Table 5 Variables influencing whether a residual ultrasound lesion is seen on interval follow-up ultrasound imaging for cases in which an attempt was originally made to completely excise the breast lesion and in which interval follow-up ultrasound imaging was obtained (n = 170)
All cases (n = 170) | No residual ultrasound lesion seen (n = 151) | Residual ultrasound lesion seen (n = 19) | P-value | |
|---|---|---|---|---|
Was the original breast lesion palpable | 0.242 | |||
Yes | 77 (45%) | 66 (44%) | 11 (58%) | |
No | 93 (55%) | 85 (56%) | 8 (42%) | |
