Regional blood perfusion and biological characteristic of breast cancer / 中国普通外科杂志

ABSTRACT

Objective To evaluate the correlation between regional blood perfusion and biological features of breast cancer. Methods Spiral CT technique was applied to quantitatively detect the central and marginal blood perfusion, including blood flow ( BF ) , blood volume ( BV) and permeability of surface (PS). Results The central and marginal blood perfusion of breast cancer were significantly higher than that of normal breast tissues. The marginal blood perfusion was higher than central blood perfusion. The regional blood perfusion of breast cancer varied with tumor size, clinical stage and histological grading. Conclusion The regional blood perfusion correlates with biological markers in breast cancer and can be used to evaluate the biological characteristics as a noninvasive marker before neoadjuvant chemotherapy.
