Table 2 Positive proximal margin rates for specimens with 0.5 cm and 1 cm resection margins
No. of specimens | Negative Margin | Positive Margin | + Margin Rate | |
|---|---|---|---|---|
0.5 cm resection margin | 10 (specimens with FP = 0) | 5 | 5 | 50.0% |
1 cm resection margin | 14–3(specimens with FP) = 11 | 10 | 1 | 9.0% |
