Table 4. SCCA expression correlates to advanced stage breast carcinomas.

	# SCCA Positive/Total Breast Carcinoma Specimen
Normal/Non-Neoplastic	0/55
Stage I	14/573 (2.4%)
Stage II	12/391 (3.1%)
Stage III	15/174 (8.6%)
	p = 0.0005

The Stage I, Stage II, and Stage III prognostic TMAs were obtained from CDP. IHC was against SCCA. The tissue was scored and the SCCA-positive cases are shown in parentheses against the number of cases for each stage. Note that all of the normal tissue were SCCA-negative, whereas 14 out of 573 (2.4%) Stage I, 12 out of the 391 (3.1%) Stage II, and 15 out of 174 (8.6%) Stage III cases were SCCA-positive.
