title: Angiogenesis and p53 protein expression in breast cancer: prognostic roles and interrelationships.
abstract: The authors have analyzed, on the one hand, the prognostic impact of microvessel density (MVD) and p53 protein expression in patients with breast cancer, and on the other hand, the correlation between the microvascular pattern and the p53 protein expression. Tumors from 120 patients whose paraffin-embedded tissue blocks were available were analyzed using the immunohistochemical method. MVD and p53 protein expression were correlated with histologic grade and tumor size, respectively. The patients with highly vascularized tumor (high MVD) had decreased overall survival (p = 0.04), whereas overexpressed p53 patients did not. In multivariate analysis, axillary lymph node status (p = 0.007), tumor size (p = 0.01), and MVD (p = 0.02) showed important prognostic influence on overall survival. When the simultaneous influence of MVD and p53 protein expression on survival were analyzed, no interrelationship was detected. The results demonstrate the prognostic impact of MVD on overall survival in breast cancer and no association between MVD and p53 protein expression.
