Background:
Esophageal carcinoma is a common kind of malignant tumor and about 90% of which is esophageal squamous cell carcinoma (ESCC), and it has a high incidence in China. In recent years it has been argued that angiogenesis plays a key role in tumor growth and metastasis and it is a complex process influenced by many factors. This study was aimed to investigate the expression of PC cell-derived growth factor (PCDGF or progranulin) and vascular endothelial growth factor (VEGF) in ESCC tissue and their relationship with clinical pathological parameters of ESCC, clarify the role of PCDGF and VEGF in the angiogenesis of ESCC.
Methods:
The expression of PCDGF and VEGF in 50 surgical specimens from patients with ESCC and 20 with normal esophageal mucosa were detected by immunohistochemistry. The vascular endothelial cells in tumor tissues were labeled by antibody to CD105 for counting microvessel density (MVD).
Results:
The expression of PCDGF and VEGF in ESCC was significantly higher than that in normal mucosa. Expression correlated with the depth of tumor invasion, lymph node metastasis, and TNM (classification tumor, nodes, metastasis). In ESCC, both the expression level of PCDGF and VEGF had a positive correlation with MVD and the expression of PCDGF had a significant correlation with the expression of VEGF.
Conclusions:
These results show that both of PCDGF and VEGE have higher expression in ESCC, which indicate that they have a close relationship with angiogenesis. They may be involved in tumor growth, infiltration and metastasis through promoting tumor angiogenesis and may be an important index reflecting biological behavior and prognosis of ESCC.
