Abstract
Objective To investigate the role of cathepsin D in facilitating tumor cells invasion and metastases by comparing cathepsin D expression with clinical and biological indicators in breast cancer. Methods By immunohistochemical SP method. Results The positive rate of cathepsin D expression in all breast cancer patients was 68.8%(110/160). Cathepsin D expression was positive correlated with that of VEGF, c-erbB-2 as well as tumor size, clinical stage and histological grade (P< 0.01), but was negati...
