Angiogenesis is an early event in tumorigenesis and facilitates tumor progression and metastasis. This study was performed to evaluate the expression of vascular endothelial growth factor (VEGF), phospholipase C-gamma1 (PLC-gamma1) and Ki-67, and to assess the relationship between them in cervical squamous cell neoplasia. The materials were fifty cervical squamous cell lesions, consisted of thirty HSIL (6 moderate dysplasia, 11 severe dysplasia, 13 carcinoma in situ), and twenty invasive squamous cell carcinoma (ISCC) cases. Immunohistochemical stain for VEGF, PLC-gamma1 and Ki-67 were done. Expression rate of VEGF was significantly higher in ISCC than in HSIL (p=0.012). PLC-gamma1 expression was significantly higher in ISCC than in HSIL (p=0.004). Ki-67 labelling index was significantly higher in ISCC than in HSIL (p=0.001) and higher in VEGF-positive tumors than in VEGF-negative tumors (p=0.018), but there were no significant differences between PLC-gamma1 expression and Ki-67 labelling index (p>0.05), and between PLC-gamma1 and VEGF (p>0.05). This study suggests that PLC-gamma1 and VEGF may play an important role in tumor cell proliferation and invasion, and these may be a useful marker to predict the possibility of invasion in cervical cancer.
