Mammaglobin-A expression and correlation with breast cancer prognostic factors.

Prognostic Factor	Mammaglobin-A Expression
Tumor Subtype and Stage	Variable expression with positivity rates ranging from 59% to 100% for lobular breast carcinomas and 25% to 94% for invasive breast carcinomas
Hormone Receptor Status	Elevated levels correlate with estrogen receptor (ER) and progesterone receptor (PR) status
Tumor Grade	High tumor grade associated with overexpression of human mammaglobin (hMAM)
Cell Proliferation	Higher Ki-67 proliferation index observed in hMAM-positive invasive breast cancer
Peritumoral Expression	Presence detected, suggesting a possible link with local invasion, metastasis, and aggressive disease phenotypes
