Prognostic Significance of Microvessel Density Determining by Endoglin in Stage II Rectal Carcinoma: A Retrospective Analysis

Figure 5

Receiver operating characteristic (ROC) curve analysis for optimal cut-off point of CD105-MVD. According to the ROC curve analysis the hypervascularized tumours were discriminated from the hypovascularized tumours. ROC analysis indicated an optimal cut-off of 179.7 microvessel/mm² in prognostic survival in stage II rectal cancer (Figure 6). Area under the ROC curve (AUC): 0.587, .
