Abstract
To clarify the role of the expression of adhesive molecules [CD44 (standard form) and sialyl Lewis A (sialyl Lea)] on hepatic metastasis, 108 advanced gastric carcinomas and 94 advanced colorectal carcinomas were investigated immunohistochemically. Multivariate analysis demonstrated that CD44 expression and lymph node metastasis in gastric cancer and CD44 and sialyl Lea expression in colorectal cancer were significantly related to hepatic metastasis. The incidence of hepatic metastasis was highest in patients with the expression of both CD44 and sialyl Lea. The expression of CD44 standard form as well as sialyl Lea may have a major role as adhesion molecules in the process of hepatic metastasis.
