Abstract

PURPOSE: Membrane type 1 matrix metalloproteinase is a membrane-associated matrix metalloproteinase central to the degradation of basement membrane components via the activation of matrix metalloproteinase-2. Although membrane type 1 matrix metalloproteinase is overexpressed in invasive colon cancer, its expression in colonic polyps and carcinoma in situ has not been defined. In addition, the association of membrane type 1 matrix metalloproteinase expression by a primary tumor and recurrence of colon cancers has not been examined. METHODS: Immunoperoxidase staining was performed on randomly selected specimens containing adenoma (n = 17), carcinoma in situ (n = 9), or metastatic colon carcinoma (n = 8) with mouse monoclonal antibody to human membrane type 1 matrix metalloproteinase. Similar staining was also performed on randomly selected node-negative colon cancers that recurred within five years of resection (n = 17), matched for age, gender, stage, grade, and vascular, lymphatic, and perineural invasion, and node-negative colon cancers that did not recur within five years of resection (n = 17). Staining for membrane type 1 matrix metalloproteinase was graded. Mean scores for the groups were compared by Wilcoxon test. RESULTS: We found a progressive and significant increase in the mean score of membrane type 1 matrix metalloproteinase from normal mucosa to adenoma (P < 0.001), carcinoma in situ (P < 0.006), and invasive cancer (P < 0.009). However, there was no difference in membrane type 1 matrix metalloproteinase expression between the recurrent and nonrecurrent groups of node-negative colon cancer (P = not significant). CONCLUSIONS: These data suggest that membrane type 1 matrix metalloproteinase expression increases with progression from normal mucosa to invasive adenocarcinoma; however, it cannot be used as a prognostic indicator on which adjuvant therapy is based in node-negative colon cancer because of its failure to predict recurrence in this patient group.
