Endothelial cell adhesion molecules (CAMs) are important in tumorigenesis and host defense mechanism. Their status in breast cancer with regard to nodal invasion is not yet known. Hence we looked at the expression of three important CAMs: VCAM, ICAM and E-selectin. A downregulation of all these CAMs was noted in node positive breast cancer in comparison to node negative cases. This suggests shedding of these molecules in cases with nodal metastasis which might help the tumor cells to escape the host defense mechanism. On multivariate analysis, VCAM alone emerged as an independent predictor of nodal metastasis.
