Table 2 Comparison of Intraoperative Inking Regimen with Standard Inking Regimen

From: The effect of intraoperative specimen inking on lumpectomy re-excision rates

  Specimen inking regimen
Measurement Intraoperative
(n = 26)
Standard
(n = 39)
P-value
1a. No. patients with positive/close margins at original surgery 6 (23%) 18 (46%) 0.06
*Positive margins 4 (15%) 7 (18%)  
*Close margins 4 (15%) 15 (38%)  
1b. No. patients who underwent re-excision 5 (19%) 15 (38%) 0.16
†Re-excision lumpectomy 3 (12%) 11 (28%)  
†Mastectomy 3 (12%) 6 (15%)  
2. No. patients with residual disease identified on re-excision lumpectomy 2 of 3 (67%) 3 of 11 (27%) 0.5
3. Residual disease identified in the specific margins at re-excision lumpectomy 4 of 5 (80%) 4 of 20 (20%) 0.02
4a. No. patients with positive/close margins on original lumpectomy specimen alone 9 (35%) 22 (56%) 0.08
4b. No. patients with positive/close margins on original lumpectomy specimen who had extra margins taken at original surgery 5 of 9 (55%) 11 of 22 (50%) 0.78
4c. No. patients with positive/close margins on original lumpectomy specimen whose margins were cleared by extra margins taken at original surgery 3 of 9 (33%) 4 of 22 (18%) 0.36
5. No. extra margins taken at original surgery that corresponded to positive/close margins on original lumpectomy 6 of 7 (86%) 15 of 19 (79%) 0.70
  1. * Some patients had positive as well as close margins
  2. † Some patients first underwent re-excision lumpectomy prior to ultimately converting to mastectomy
