Table 3.
Device detection rate for tumor at the margin by histological subtypes
| Cancer histopathology | Number of samples (n) | Detected samples (n) | Detection rate (%) | |||
|---|---|---|---|---|---|---|
| Invasive cancer | ≤1 mm | On‐ink | ≤1 mm | On‐ink | ≤1 mm | On‐ink |
| IDC | 13 | 6 | 11 | 6 | 85 | 100 |
| ILC | 6 | 1 | 5 | 0 | 83 | 0 |
| IDC + DCIS | 2 | 0 | 2 | NA | 100 | NA |
| All | 21 | 7 | 18 | 6 | 86 | 86 |
| Noninvasive cancer | ||||||
| DCIS, ADH | 33 | 17 | 52 | |||
Note: The table presents a number of histology positive margins per subtypes and the corresponding margins detected by the ClearSight™ system.
Abbreviations: ADH, atypical ductal hyperplasia; DCIS, ductal carcinoma in situ; IDC, invasive ductal carcinoma; ILC, invasive lobular carcinoma.
