Significance of intratumoral microvessel density quantification based on immunohistochemical detection of PECAM-1 and vWF in colorectal carcinoma from Iraqi patients

Abstract
Context: Counting of newly formed microvessel may prove to be a useful tool in the early detection
of metastatic potential and selection of patients for whom antiangiogenesis drugs might be
beneficial. Aims: We designed this study to assess the significance of microvessel quantification in
colorectal cancer with respect to different clinicopathological variables.
