摘要
Abstract
Our objectives were to measure the relationships between conventional ultrasound features, strain elastography in breast cancer and Ki-67 index and to identify parameters that predict Ki-67 index. We included 181 lesions of 178 patients who underwent surgery for breast cancer at Xianyang Central Hospital. In multivariate logistic regression analysis, strain elastography and axillary-node metastasis showed significant Ki-67 index values; the overall theoretical prediction percentage correct was 75.7%. Strain elastography showed that the median Ki-67 index in the hard group was higher than that in the soft group, and the Ki-67 index increased with increasing elasticity score. This finding may guide ultrasound-guided breast tumor biopsy for selection of puncture regions. The combined use of the Ki-67 index for strain-elastography prediction and puncture-biopsy pathology reports may increase the accuracy of clinical treatment.
