Breast cancer (BC) stands out as the most diagnosed cancers in women. Therefore, it is important to diagnose BC patients at the early stages. Human Mammaglobin (MAM-A) is recently shown to specifically express in BC and its increased expression were found in primary breast cancer comparing with undetectable or low levels in non-breast tumors or normal breast tissue. Our aim was to investigate the level of expression for MAM-A as prognostic marker, and its correlation with the clinicopathological characteristics of BC patients. A set of 746 cases of BC, including 371 cases of lymph node (LN) positive, were employed. The immunohistochemistry staining of MAM-A was scored manually under a light microscope based on the intensity of the patterns measured stained slides by Automated Immunohistochemistry (IHC) slide staining system. The results showed significant increase in expression of cytoplasmic MAM-A, associated with triple negative, HER2 expressions and hormone receptor phenotypes, and p-values were (p<0.001), (p<0.01), (p=0.021) respectively. However, nuclear MAM-A expression showed no significant correlation with any clinicopathological features in this study. Moreover, Kaplan-Meier analysis showed no significant difference in survival behaviour with positive expression of cytoplasmic or nuclear MAM-A and no association with tumor recurrence were observed. Therefore, our results showed that MAM-A may act as prognosis marker for some type of BC that may involve triple negative, hormone receptor and HER2 phenotype.
