TABLE 3.

Histological assessment of carcinoma and benign breast tissue at the skin-sparing mastectomy (SSM) superficial specimen margin does not predict involvement of additional superficial margin (ASM)

	ASMs with carcinoma (N = 13)	ASMs without carcinoma (N = 51)	P-value
Carcinoma transected at the mastectomy superficial margin	6	19	0.7520
Carcinoma less than 1 mm of the Superficial specimen margin	7	32
Extent of involvement by carcinoma at the Superficial specimen margin (mm) (range)	12.5 ± 15.8 (2–58.5)	11.0 ± 17.4 (0.5–85)	0.7927
Benign breast tissue transected at the Superficial specimen margin	9	25	0.2219
