Gu J, Polley EC, Boughey JC, et al. - This study was carried out to compare a new shear-wave elastography (SWE) parameter, mass characteristic frequency, and other elasticity measures with the prognostic histological factors and immunohistochemical biomarkers for the evaluation of heterogeneous breast carcinomas. Researchers enrolled 264 biopsy-proven breast cancerous masses. It was shown that poor prognostic factors were correlated with high shear wave elasticity values and low mass characteristic frequency values. The results demonstrate that SWE provides valuable information that may help with the prediction of breast cancer invasiveness.
