Abstract
Objective The purpose of this study is to discuss the diagnostic value of different ADC values on ductal carcinoma in situ (DCIS) so as to evaluate the preoperative prediction invasive component. Methods A total of 69 DCIS female patients with 70 lesions confirmed by pathology during June 2014 and October 2016 were included in this study; all of them underwent preoperative MRI. We selected the highest and lowest ADC value from the region of interest, and calculated the difference value between them. The differences between the DCIS and DCIS invasive component were compared. Results The minimum ADC value in DCIS invasive component was much lower than that of DCIS (P=0.0037). The difference value between maximum ADC and minimum ADC in DCIS invasive component was much higher than that of DCIS (P=0.0007). There was negative correlation between minimum ADC value and difference value (r=0.65). ROC showed that the effective threshold-value of ADC maximum value less than 1.1×10-3mm2/s was contributed to identification of DCIS invasive component and DCIS, with sensibility and specificity of 72% and 77%. Similarly, the effective threshold-value of difference value of ADC higher than 0.23×10-3mm2/s was also contributed to identification of DCIS invasive component and DCIS, with sensibility and specificity of 68% and 76%. Conclusion Both the minimum ADC value and the difference value between the minimum and maximum are helpful for identifying of DCIS invasive component and DCIS, which can help to determine if the sentinel lymph node and axillary lymph node could be swept.关键词
