Abstract
The clinical relevance of the receptor for advanced glycation end products (RAGE) and amphoterin expression was examined in 119 non-diabetic patients with colorectal carcinoma. Expression of RAGE was examined by immunohistochemistry and that of amphoterin by in situ hybridization. RAGE expression was observed in 55% (64/119) of the cases. RAGE positivity in Dukes' B, C and D cases was 19, 81 and 100%, respectively (p<0.0001). Amphoterin was expressed in most cases regardless of tumor stage. Survival analysis of Dukes' B and C cases showed a significantly poorer prognosis for patients with co-expression of RAGE and amphoterin than for patients without co-expression. The results suggest that co-expression of RAGE and amphoterin is closely associated with invasion and metastasis of colorectal cancer.
