| Outcome | Patients with cancer n = 242 | Patients undergoing CPM n = 69 | Patients undergoing BPM n = 26 | p value |
|---|---|---|---|---|
| Nipple margin assessment performed | 222/242 | 57/69 | 17/26 | < 0.001 |
| Positive margin | 10/222 | — | — | 0.18 |
| Surgery based on nipple margin result | 7/10 | — | — | — |
