Clinical Value of MRI in Predicting Luminal Staging of Nonspecific Invasive Ductal Carcinoma of the Breast
Objective:To investigate the MRI manifestations of Luminal staging of non-specific invasive ductal carcinoma of the breast,and to provide better options for the management of non-specific invasive ductal carcinoma of the breast.Methods:Clinical and imaging data of 119 female patients with surgical pathologically confirmed non-specific invasive ductal carcinoma of the breast from October 8,2018 to December 1,2021 were retrospectively analyzed.Clinical features and MRI imaging features of Luminal and non-Luminal types were compared.ROC curves were plotted and the area under the ROC curve and cut-off points were calculated.Results:Of the 119 cases of non-specific invasive ductal carcinoma of the breast,72 were of the Luminal type and 47 of the non-Luminal type.The difference between patients with or without lymph node metastasis,tumor maximum diameter,morphology,TIC curve,minimum apparent diffusion coefficient(ADC)value and average ADC value were statistically significant(P<0.05).When the minimum and mean ADC values were 0.851×10-3 mm2/s and 0.849×10-3 mm2/s,respectively.Their specificities and sensitivities were 0.553,0.806,0.681,0.750.The areas under the ROC curves were 0.745 and 0.761,respectively.Conclusion:MRI can improve the diagnostic efficacy of non-specific invasive ductal carcinoma of the breast,and its ADC value can be used as an important indicator of its clinical and prognostic value,which is more conducive to more accurate clinical treatment.
