Mortalin protein expression in breast cancers

Diagnosis	No. of cases	Positive cases	Positive cases rates	Strongly positive rates
		- + ++ +++
Invasive ductal carcinoma of breast	155	34 22 53 46	78.1 %**	63.9 %**
DCIS	52	24 10 12 6	53.8 %*	34.6 %*
Adjacent non-tumor	45	32 6 7 0	28.9 %	15.6 %

DCIS; ductal carcinoma in situ

Positive rate: percentage of positive cases with +, ++, and +++ staining score. Strongly positive rate: (high-level expression) percentage of positive cases with ++ and +++ staining score

* p < 0.05 and ** p < 0.01 compared with non-tumor tissues
