OBJECTIVE: The purpose of this study was to evaluate the association between the @entity0 strain ratio and @entity1600 in @entity1 with @entity0 . MATERIALS AND METHODS: The records of 284 @entity1 with @entity0 who underwent ultrasound elastography before surgery between March 2013 and May 2014 were reviewed retrospectively. For @entity1 with @entity5 , the largest @entity5 was included. An experienced radiologist performed ultrasound elastography and measured the strain ratio, which is defined as the fat-to-lesion ratio and is indicative of the relative stiffness of the @entity1558 , using dedicated software within the ultrasound equipment. The associations between @entity1600 with the @entity5 strain ratio and clinical and biologic variables were evaluated using univariate and multivariate logistic regression analyses. RESULTS: Among 284 @entity5 , 85 (29.9%) showed @entity1600 by surgical histopathologic analysis. The strain ratio was statistically significantly higher in @entity5 with @entity1600 than in those without @entity1600 (mean    SD, 5.19    1.28 vs 4.17    1.30, respectively; p < 0.001). On univariate analysis, a higher strain ratio (> 3.89), larger @entity5 size (> 2 cm), higher histologic grade (grade 3), presence of @entity3 , palpability, and higher expression of Ki-67 (>=  14%) were statistically significantly associated with @entity1600 . On multivariate analysis, a higher strain ratio (> 3.89) (odds ratio [OR], 14.208; p < 0.001), presence of @entity3 (OR, 17.437; p < 0.001), and higher expression of Ki-67 (>=  14%) (OR, 3.744; p = 0.002) maintained independent significance for predicting @entity1600 . CONCLUSION: The @entity0 strain ratio on ultrasound elastography is associated independently with @entity1600 in @entity1 with @entity0 .

The @entity0 Strain Ratio Is a Predictive Parameter for Axillary Lymph Node XXXX in @entity1 With @entity0 .
