  • Correlaiton Between Dynamic Contrast Enhanced Magnetic Resonance Imaging and WHO Histological Grade in Patients with Invasive Ductal Breast Cancer

    ObjectiveTo investigate the relationship of dynamic contrast enhanced(DCE) MRI scan of the mass type of invasive ductal breast cancer to histological grade. MethodThe imagings of DCEMRI of 92 patients confirmed with operation or biopsy pathology and its correlation with WHO histological grade were analyzed. ResultsThere were 29(31.52%) patients with the tumor long diameter≤2 cm, 53(57.61%) 2-5 cm, 10(10.87%)≥5 cm. There were 3(3.26%) patients with round of the morphological lesions, 7(7.61%) oval, 33(35.87%) lobulated shape, 49(53.26%) irregular shape. There were 11 (11.96%) patients with smooth margin of the periphery of the lesions, 47 (51.09%) irregular shape, 34(36.96%) spiculate margin. There were 15(16.30%) patients with homogeneous enhancement, 40(43.48%) heterogeneous enhancement, 37(40.22%) ring-like enhancement. WHO pathological grade:grade 1 was in 5 cases(5.43%), grade 2 in 30 cases(32.61%), grade 3 in 57 cases(61.96%). The statistical results showed that MRI dynamic enhancement characteristics of lesions in size, shape, and enhanced features were correlated with WHO pathological grade (P < 0.05), there was no correlation between the edge features of the tumor and WHO histological grade(P > 0.05). ConclusionThere is a certain correlation between the breast cancer enhanced MRI features and WHO histological grade, which can be evaluated biological behavior and prognosis according to MRI signs of lesions.
