Prognostic value of intercellular adhesion molecule (ICAM)-1 expression in breast cancer

Purpose The intercellular adhesion molecule (ICAM)-1 is expressed on many cell types including endothelial cells and different cancer cell entities. Experimental data strongly indicate that ICAM-1 can activate intracellular signalling pathways in cancer cells leading to enhanced cell motility, invasion and metastasis. Yet, little is known about the role of ICAM-1 expression during malignant progression in breast cancer patients.
