Purpose: The purpose of this study was to correlate power Doppler sonographic findings with histologic grade in patients with invasive breast cancer.
Materials and Methods: One hundred and ninety-one women (age range, 26-75 years; median age, 52 years) with breast masses evaluated with sonography and subsequently proven to be invasive ductal carcinoma not otherwise specified, composed our study population. Two radiologists quantified the lesion vascularity at power Doppler sonography and results obtained were correlated with histologic tumor grades.
Results: Of the 191 invasive ductal carcinomas, vascularity was seen in 97% (74 of 76) of high-grade tumors, 71% (65 of 92) of intermediate-grade tumors, and 26% (6 of 23) of low-grade tumors. Hypervascularity was seen in 63% (48 of 76) of high-grade tumors but in only 17% (16 of 92) of intermediate-grade tumors and not al all in low-grade tumors. Tumor vascularity at power Doppler sonography was significantly associated with a mass margin (p < .001) and acoustic transmission (p < .001) at gray scale sonography, and was found to be correlated with histologic grade (r = 0.598, p < .001).
Conclusion: Tumor vascularity at power Doppler sonography was correlated with histologic grade.
