Tissue expression of VEGF as a prognostic factor in early cervical squamous cell carcinoma.
The purpose of this retrospective study was to determine whether the intensity of tumor angiogenesis, expressed as microvessel density (MD), is indeed an important parameter predicting lymph node metastasis and survival rate in 73 women operated on for early invasive squamous cell carcinoma of the uterine cervix in stages Ib and IIa (FIGO). Angiogenesis was quantified by light microscope (LM) using an assay for vascular endothelial growth factor (VEGF). In the study, differences were revealed by comparing the MD between both groups. The patient survival with high MD was significantly worse than for those with low MD (p<0.01). A correlation was found between MD and the incidence of lymph node metastases. Hence, quantitative analysis of MD used as the expression of VEGF in the each cervical squamous cell carcinomas could be useful as a significant prognostic indicator.
