Abstract
Objective To discuss the value of conventional ultrasonography and elastography in diagnosis of axillary lymph nodes in breast cancer patients. Methods Conventional ultrasonography and elastography were applied to examine 80 axillary lymph nodes of 79 patients with breast cancer, the results were compared with histopathological outcomes. Results There were 60 malignant and 20 benign lymph nodes in the 79 breast cancer patients. In the malignant lymph nodes, the morphology was mainly type Ⅱ and Ⅲ, the blood flow was mainly type Ⅲ, the elasticity score was primarily 3 and 4, the cut-off of ratio of elastic strain rate was 2.42. The sensitivity, specificity and accuracy of conventional ultrasonography for diagnosis of lymph node metastasis were 53.3%, 95.0% and 63.4% respectively, those of elastic score were 93.3%, 90.0% and 92.5%, those of elastic strain rate ratio were 91.7%, 95.0% and 91.2% respectively. There were significant differences in the accuracy of the diagnostic results among the three methods (χ2 = 32.121, < 0.05). Conclusions Elastography can be used as an effective method to assess lymph node status. It is complementary to the conventional ultrasonography for the differential diagnosis of axillary lymph nodes in patients with breast cancer.关键词
