Relative expression of E-cadherin and type IV collagenase genes predicts disease outcome in patients with resectable pancreatic carcinoma

Clin Cancer Res. 1999 Jan;5(1):25-33.

Abstract

We examined the expression level of several genes that regulate distinct steps of metastasis in formalin-fixed, paraffin-embedded, archival specimens of primary human pancreatic carcinomas from patients undergoing curative surgery. The expression of epidermal growth factor receptor, E-cadherin, type IV collagenase [matrix metalloproteinase (MMP) 2 and MMP-9), basic fibroblast growth factor, vascular endothelial growth factor/vascular permeability factor, and interleukin 8 was examined by a colorimetric in situ mRNA hybridization technique. Down-regulation of E-cadherin and up-regulation of type IV collagenase (MMP-9 and MMP-2) at the periphery of the neoplasms (P = 0.0167, 0.0102, and 0.0349, respectively) had significant prognostic value. The ratio of type IV collagenase expression (mean of the expression of MMP-2 and MMP-9) to E-cadherin expression (MMP:E-cadherin ratio) at the periphery of the tumors was significantly higher in patients with recurrent disease (4.7 +/- 2.1) than in patients who were disease free (2.3 +/- 1.7; P = 0.0008). Death from pancreatic cancer was significantly associated with a high MMP:E-cadherin ratio (>3.0) by overall survival analysis (P < 0.0002), whereas a low MMP:E-cadherin ratio (<3.0) was found in seven of eight patients alive 28-64 months after surgery. Multivariate analysis of overall survival showed that the MMP:E-cadherin ratio was a significant independent prognostic factor, whereas stage, nodal metastasis, and histological type were not. These data show that multiparametric analysis for several metastasis-related genes may allow physicians to assess the metastatic potential and hence predict the clinical outcome of individual patients with resectable pancreatic carcinoma.
