Cell adhesion molecules (CAMs) are cell surface glycoproteins that are important in cell-cell and cell-matrix interactions and play an important role in cell growth and differentiation. We examined immunohistochemically CD44s, CD44v6 and E-cadherin expression in 86 formalin-fixed, paraffin-embedded primary tumours and 5 metastases. Lower levels of CD44s, CD44v6 and membranous E-cadherin expression were significantly associated with higher tumour grade (p=0.022, p=0.016 and p= 0.041, respectively). Moreover, CD44v6 and membranous E-cadherin expression were correlated with the depth of primary tumour invasion (p=0.030 and p=0.020, respectively), and increased expression of CD44v6 and decreased membranous E-cadherin expression were associated with increased primary tumour invasion. The results suggest that these CAMs are associated with tumour differentiation and invasion in locally advanced and metastatic colorectal carcinoma.
