Title: [Microvessel density, epithelial-stromal vascular cuffing and expression of vascular endothelial growth factor in human cervical carcinoma].
Abstract: To observe microvessel density(MVD), epithelial stromal vascular cuffing(VC) and expression of vascular endothelial growth factor(VEGF) in human cervical carcinomas and to clarify their significance in the invasion and metastasis of cervical carcinoma.VEGF and CD34 were stained immunohistochemically (SP) in 57 cases of cervical carcinoma (30 cases of squamous cell carcinoma, 20 of adenocarcinoma 7 of glandular and squamous cell carcinoma), 29 cases of cervical intraepithelial neoplasia (CIN) and 16 cases of normal cervices, meanwhile, MVD and VC were also assayed.There were significant differences among the above 5 groups for MVD P<0.01 . The VC pattern showed a significant difference between cervical carcinoma and CIN or control group P<0.01). The positive rates of VEGF in normal cervical epithelium, CIN, squamous cell carcinoma, adenocarcinoma, glandular and squamous cell carcinoma were 18.8% 3/16, 82.8% 24/29), 93.3% 28/30), 100% 20/20 and 7/7(100%), respectively. There were significant differences between these cervical lesion groups and the control group(P<0.001). The MVD showed significant differences between the positive pelvic node metastasis and negative pelvic node metastasis P<0.05). There was no significant correlation between the expression of VEGF and the tumor diameter, clinical stage, pathologic grade and pelvic node metastasis.The expression of VEGF may play an important role in the angiogenesis of cervical carcinoma. Degree of malignancy of cervical carcinoma has a close association with microvessel density.
