Abstract:
OBJECTIVE:To explore the discrepancy of HGF and Hpa expressed in laryngeal squamous cell carcinoma of different pathology grades (differentiation of high, moderate or poor), which can provide the new thought and theory evidence for clinical treatment and control metastasis or palindromic.
METHOD:Forty paraffin-embedded samples of laryngeal squamous cell carcinoma, forty paraffin-embedded samples of laryngeal papilloma and twelve paraffin-embedded samples of normal tissue adjacent to cancerous location of our department between May 2004 and April 2005, which were analyzed with SP immunohistochemistry staining.
RESULT:The positive rate of HGF were 77.5% and that of Hpa were 72.5% in laryngeal squamous cell carcinoma, which have positive correlation and were higher than that in laryngeal papilloma and normal tissue adjacent to cancerous location with significant statistical difference (P<0.01). The expression of HGF and Hpa had no relationship with primary locations (P>0.05), that have positive correlation with clinical stages and have negative correlation with the level of cellular differentiation. The expression of HGF and Hpa in lymph node metastasis group was significantly higher than the non-metastasis group (P<0.05).
CONCLUSION:The expression of HGF and Hpa in laryngeal squamous cell carcinoma are higher than that in nonmalignant ones. They correlates with lymph node metastasis, clinical stages and pathological grading, but they has no relationship with the primary locations. The positive correlation relationship of expression between HGF and Hpa might be worthiness to determine the prognosis of laryngeal squamous cell carcinoma.
