background : angiogenesis is essential for the growth, invasion and metastasis of solid tumors. research on related factors such as microvessel density can be helpful in predicting a tumor's behavior. cd105 has been introduced as a marker of angiogenesis which stains vessels that are in the proliferating stage. there are some controversies about the relation of microvessel density and clinicopa...

Introdution: Angiogenesis is important for tumor growth and metastasis. It is determined by microvessel density (MVD). The goal of this study was to evaluate microvessel density in the salivary glands mucoepidermoid carcinoma (MEC) and its association with histological grading. Methods: In this cross-sectional study, 17 mucoepidermoid carcinoma paraffin blocks were extracted. CD34 immunohistoc...

OBJECTIVE To evaluate the prognostic significance of microvessel density and p53 expression in pancreatic cancer. METHODS Between 2008 and 2012, 49 patients with pancreatic adenocarcinoma underwent resection with curative intention. The resected specimens were immunohistochemically stained with anti-p53 and anti-CD34 antibodies. Microvessel density was assessed by counting vessels within ten ...

AIM To compare endoglin (CD105) and the pan-endothelial marker CD31 in the assessment of angiogenesis in glioblastoma and to evaluate their values in the prognosis of this malignancy. METHODS Forty-six cases of glioblastoma were included in this retrospective study. All cases were immunohistochemically stained for endoglin (CD105), CD31, vascular endothelial growth factor (VEGF), and MIB-1 (K...

To determine whether vascular endothelial growth factor (VEGF) expression and microvessel density are predictive of prognosis in cases of invasive cervical cancer, correlations among VEGF expression, microvessel density, and clinicopathological parameters were identified. VEGF expression was evaluated in 50 cervical cancer samples by immunohistochemical staining. Microvessel density was assesse...

UNLABELLED Angiogenesis is new blood vessel formation, a process that can lead to tumor development. Microvessel count has been correlated to metastasis in some neoplasias. PURPOSE To determine if measurement of microvessel density is useful in predicting metastasis to the cervical lymph node and prognosis in patients with papillary thyroid carcinoma. METHODS A retrospective analysis was pe...
