Popis: There is now much data that suggest a relationship between angiogenesis and breast cancer prognosis. Angiogenesis is a multistep process resulting from an ordered set of events and regulated by positive and negative modulators of microvessels growth and by the expression of various proteolytic enzymes.We prospectively evaluated VEGF and microvessels density on tumor specimen and cytosolic levels of uPA and PAI-1.We enrolled 81 primary breast cancer patients. The median follow-up was 38 months. Using the median value as cutoff for the statistical analysis, we found significant correlation between cytosolic levels of uPA and PAI-1 (r = 0.61; p.0001), between VEGF and steroid hormone receptor status (p = .01), between PAI-1 and tumor grading (p = .009), and between uPA and tumor size greater than 1 cm (p = .04). With respect to the prognosis, we observed a significant correlation between low uPA levels and RFS and an unforeseen, direct correlation between high VEGF values and better RFS.Our preliminary results indicate that the cytosolic level of uPA at diagnosis may be predictive of early relapse in primary breast cancer.
