Abstract: The purpose of this study was to explore the relationship between dynamic enhancement of magnetic resonance, miR-27, miR-155 expression and breast cancer. One hundred breast cancer patients were selected as the observation group, and another 60 patients with benign breast lesions were selected as the control group. This study compared the two groups’ DCE-MRI quantitative parameters [transport constant (Ktrans), rate constant (Kep), extravascular intercellular space fraction (Ve)] and the expression of miR-27 and miR-155, and then performed correlation analysis to evaluate its diagnostic power. The expression levels of Ktrans, Kep, miR-27 and miR-155 in the observation group were higher than those in the control group (P<0.05). The expression levels of Ktrans and Kep in breast cancer patients were significantly positively correlated with the expression levels of miR-27 and miR-155 (P<0.05). Ktrans, Kep, miR-27 and miR-155 were independent influencing factors of breast cancer (P<0.05). The expression of Ktrans, Kep, miR-27, miR-155 is related to histological grade, clinical stage, lymph node metastasis, progesterone and estrogen receptor expression (P<0.05). The AUC of the combined diagnosis of breast cancer by DCE-MRI quantitative parameters, miR-27, miR-155 expression is 0.905. DCE-MRI quantitative parameters (Ktrans, Kep) and the expression levels of miR-27 and miR-155 were up-regulated in breast cancer, and were related to pathological features.
