VEGF and CD105 immunoexpression in squamous cervical carcinomas and associated precancerous lesions

In this study, we analyzed the VEGF and CD105 immunoexpression in 24 cervical squamous cell carcinomas and CIN associated lesions with different degrees. For both lesions, MVD values were higher in patients who had associated risk factors. VEGF and MVD expression increased in both categories for high-grade lesions, respectively CIN III lesions compared with CIN I/II and poorly differentiated carcinomas compared with well-differentiated ones. Also, there was a statistically significant association between VEGF and MVD in poorly differentiated carcinoma and CIN III. The study indicated that analyzed markers were specific for both early and advanced stages of cervical angiogenesis. Maximum values of VEGF and MVD in CIN III designate this lesion as critical to the progression of neoplasia.
