Abstract
Objective
To investigate the correlation among MRI morphologic features, pathology, and molecular biology of breast cancer.
Methords
MRI was used to analyze the morphologic features of breast cancers of 78 patients before operation. The mastectomy specimens of the breast neoplasms were immunohistochemically stained, and the expression of the estrogen (ER), progesterone receptor (PR), C—erbB—2, P53, and the distribution of microvessel density (MVD) measured. The pathologic results were compared with the MRI features.
Results
Among the 80 breast cancers, ER positive expression was positively correlated with the spicular contour of breast cancers (P<0.01 ), while showing a significant inverse correlation with the T—stage (P<0.05). C—erbB —2 and P53 positive expression were positively correlated with the necrotic center of the cancers (P<0.05). The expression of. PR was not significantly correlated with the spicular contour, obscure margin, necrotic center, and T—stage of these cancers (P>0.05). Among 41 breast cancers examined with dynamic contrast enhanced MR, there was a positive correlation between the spatial distribution of the contrast agent and MVD (P<0.01).
Conclusion
To a certain extent there is some correlation among the MRI morphologic features, pathology, and molecular biological factors in breast cancer. The biological behavior and prognosis of breast cancer can be assessed based on MRI features.
