Methods: Fifty patients with breast cancer underwent initial diagnosis with molybdenum target radiography and confirmed pathologically in our hospital. Immunohistostaining was performed on the postoperative specimens to detect the expression of the cancer gene and immunologic factors. The mass, malignant calcification, veining and axillary lymph node metastases exposed on the mammographic images were compared with the expression of VEGF and CerbB2, and the data were summed up. Results: Of the 50 breast cancer cases, mammography revealed the mass in 37 ( 74% ) , malignant calcification in 23 ( 46% ) , veining in 19 ( 38% ) and axillary metastatic lymph nodes in 14 ( 28% ) . VEGF and CerbB2 were positively expressed in 24 and 14 , respectively, of the 50 cases. The positive rate of VEGF expression complied with the mammographical imaging signs of mass, veining and axillary metastatic lymph node was higher than that of failure of exposure of those elements( P < 0. 05 ) , and the positive expression rate of CerbB2 was also higher on the mammographs exposed malignant calcification, veining and axillary metastatic lymph node as compared with those of absence ( P < 0. 05 ) . Conclusion: The findings of molybdenum target Xray may, to a certain extent, reveal the tumor differentiation and be used to make an estimation of the prognosis, program the therapeutic regime and evaluation of the treatment effects. 【Key words】breast cancer; molybdenum target radiography; VEGF; CerbB2
