Table 2A. E-cadherin expression in primary ovarian cancer and corresponding metastases.

		Primary tumours (n=48)a		Metastases (n=50)a
E-cadherin	Score	(n)	(%)	(n)	(%)
Reduced		12	25.0	11	22.0
	0	1	2.1	1	2.0
	1+	2	4.2	1	2.0
	2+	9	18.7	9	18.0
Preserved	3+	36	75.0	39	78.0

^aFor n=47 cases, matched pairs of primary tumours and their corresponding metastases were available for analysis.

Reduced, reduced E-cadherin expression defined by scores of 0, 1+, and 2+.

Preserved, preserved E-cadherin expression defined by a score of 3+.

n, number of patients.

The main categories of ‘reduced’ and ‘preserved’ (as compared to the subcategories of reduced expression) are shown in bold.
