Table 6. Comparison of ER/PR/HER2 status with Oncotype DX assay and conventional methodology (Immunohistochemistry and fluorescence in situ hybridization ‘FISH’ testing).

n = 33			Oncotype DX testing
Conventional metholodogy			positive	negative	equivocal
ER	positive	33 (100%)	33 (100%)	–	–
	negative	–	–	–	–
PR	positive	30 (91%)	26 (79%)	4 (12%)	–
	negative	3 (9%)	1 (3%)	2 (6%)	–
HER2	positive	1 (3%)	0	1 (3%)	–
	negative	32 (97%)	–	31 (94%)	1 (3%)

In one case results of Oncotype DX for ER/PR/HER2 status were not available.
