[Tumoral vascular density in breast tumors and their effect on recurrence-free survival].

Angiogenesis quantitation of 106 patients with primary breast cancer and 35 patients with adenofibroma of the breast was compared and examined to its prognostic relevance for five-years disease-free survival in breast cancer patients. Immunocytochemical staining for Factor VIII-related antigen was performed to outline vascular endothelium. We found a significant higher vessel density in breast cancer patients who experienced recurrence (17.4) than in those with no recurrence (9.4) or with adenofibroma (8.7) [p < 0.0001]. The probability of five-years recurrence-free survival for patients with a primary tumor of high vessel density was at 52.3% and 86.4% for tumors of low microvessel density (p < 0.0011). Microvessel density proved to be an independent prognostic factor for breast cancer recurrence in the Cox-Model (relative risk 2.047, p = 0.0002).
