Methods: The expression of VEGF-C in pancreatic cancer tissue of 42 cases and normal pancreatic tissue of 10 cases was detected by using immunohistochemical S-P method. The microlymphatic vessel density (MLVD) of both tissues was measured by enzyme-histochemical method at the same time. Results: The VEGF-C positive expression rate was significantly higher in pancreatic cancer tissue (64.3%) than in normal pancreatic tissue (20%, P〈0.05). The MLVD was significantly higher in pancreatic cancer tissue (21.93±6.39) than that in normal pancreatic tissue (4.40±2.07, P〈0.001). The VEGF-C positive expression rate, MLVD and lymph node metastasis had a positive correlation. Conclusion: The VEGF-C may play an important role in the lymphangiogenesis and lymph node metastasis of pancreatic cancer.展开更多
