Abstract

Objective To study the expression of PINCH and vascular endothelial growth factor C (VEGF-C) in cervical squamous cell carcinoma.Methods We detected the expression of PINCH and VEGF-C by immunohistochemistry SP in 58 cervical squamous cell carcinoma cases and 30 normal cervical epithelial tissue and analyzed their relationship to the clinical pathological features.Results The expression of PINCH and VEGF-C in 58 cervical squamous cell carcinoma(62.1％,36/58 ;67.2％,39/58 ) were higher than that in normal cervical epithelial tissue(0,0/30).The difference was significant( x2 =31.512,12.534,P ＜ 0.001 ).The expression of PINCH protein was not significantly associated with the age,tumor size and tumor differentiation grade ( P ＞ 0.05 ),but was associated with the lymph node metastasis and clinical stage ( x2 =9.090,8.236,P ＜ 0.001 ).The expression of VEGF-C had no significant correlationship with the age and tumor size( P ＞ 0.05 ) but had a correlationship with the lymph node metastasis,tumor differentiation grade and clinical stage( x2 =10.775,13.496,5.001,P ＜ 0.05 ).The expression of VEGF-C was correlated with the expression of PINCH protein( C =0.341,P ＜ 0.01 ).Conclusion It is possible that VEGF-C and PINCH take part in the development and progress of cervical squamous cell carcinoma and play an important role in the invasion and metastasis mechanism altogether. Key words: PINCH protein; Vascular endothelial growth factor C protein; Cervical squamous cell carcinoma; Clinical pathology; Immunohistochemistry
