چکیده

There is growing evidence that cancer-associated fibroblasts (CAFs) interact with tumor cells and play important roles in tumor progression and invasion. Podoplanin is a type-1 transmembrane glycoprotein expressed in a variety of normal human tissues, including lymphatic endothelium. Tumor cell expression of podoplanin correlates with nodal metastasis and poor prognosis in squamous cell carcinoma (SCC) of oral cavity and esophagus. Recently, podoplanin-positive CAFs have been shown to exert adverse or beneficial prognostic effect on different cancer types. However, the significance of podoplanin-positive CAFs in esophageal SCC has not been investigated. This is the first study to investigate podoplanin expression in CAFs and tumor cells by immunohistochemistry in 59 cases of surgically resected esophageal SCC. We found significant association of podoplanin expression between CAFs and tumor cells (P = 0.031). Although the abundance of podoplanin-positive CAFs per se had no prognostic effect, concordant podoplanin expression in CAFs and tumor cells (both high or both low) was strongly associated with short survival (P = 0.00088). Multivariate analysis showed that concordant podoplanin expression was the strongest independent adverse prognostic factor (hazard ratio: 3.62; 95% confidence interval: 1.69-7.77; P = 0.00094). Our data suggest that interaction between podoplanin-positive CAFs and tumor cells is important in tumor biology of esophageal SCC.
