Abstract

Matrix metallopeptidase 10 (MMP10) is frequently expressed and correlates closely with metastasis and poor prognosis in various human cancers. However, the significance of MMP10 expression in esophageal squamous cell carcinoma (ESCC) and its role in ESCC progression remains unclear. In this report, upregulation of MMP10 mRNA was detected in 39/60 (65.0%) of primary ESCC tissues compared with their paired nontumor esophageal tissues. Tissue microarray (TMA) study found protein overexpression of MMP10 in 188/239 (78.7%) of primary ESCC tissues but not in their corresponding nontumor esophageal tissues, suggesting that overexpression of MMP10 may play important roles in ESCC development and progression. Although the overexpression of MMP10 was not significantly associated with disease-specific survival rate (P= 0.182) for all tested ESCCs, it was significantly associated with poorer disease-specific survival (P= 0.001) in early stage of ESCCs (I-IIA). In addition, multivariate analysis found that MMP10 expression in tumor tissues was evaluated as a potential independent prognostic factor for early stage ESCC patients. These findings suggest that MMP10 plays an important role in ESCC progression in the early stage, and overexpression of MMP10 in tumor tissues could be used as a potential prognostic marker for patients with early clinical stage of ESCC.
