This study addresses the association of matrix metalloproteinase-1 (MMP-1) and vascular endothelial growth factor-C (VEGF-C) expression in esophageal squamous cell carcinoma (SCC) with clinicopathologic characteristics in the patients.


We profiled the expression of MMP-1 and VEGF-C by cDNA microarray in 4 cases and by reverse transcription-polymerase chain reaction (RT-PCR) in 14 cases of esophageal SCC. Another 90 cases were reviewed by immunohistochemical examination of paraffin-embedded sections.


Expression of MMP-1 and VEGF-C mRNA in normal esophageal tissue and tumor tissue was compared. Data were fully consistent with the results of RT-PCR. Immunohistochemistry showed that compared to the normal mucosa MMP-1 and VEGF-C protein expression was upregulated in both esophageal atypical hyperplasia (n = 16) and esophageal SCC. Depth of tumor invasion, lymph node metastasis, and clinical stage were directly associated with prognosis in all cases. Furthermore, median overall survival and disease-free survival were significantly shorter in patients with a higher expression of MMP-1 and VEGF-C than in patients with lower expression levels.


We demonstrated that the expression of both MMP-1 and VEGF-C mRNA and protein was upregulated in esophageal SCC tissues. Protein expression was associated with progressive tumor stage and poor prognosis in patients with esophageal SCC.
