Methods: A total of 76 patients with primary breast cancer who were diagnosed and underwent radical mastectomy in our hospital between May 2016 and January 2018 were selected as the breast cancer group, and 89 patients with breast adenoma who underwent breast nodule resection in our hospital during the same period were selected as the breast adenoma group. The differences in lesion SWE parameter as well as the expression of proliferation, apoptosis and invasion genes in the lesions were compared between the two groups of patients, and correlation analysis was used to judge the correlation between Emax level and gene expression in breast cancer tissue. Results: The Emax level in the lesions of breast cancer group was higher than that of breast adenoma group;proliferation-related genes Ghrelin, Jab1, galectin-3, TRIM11, RRS1 and MTDH mRNA expression in the lesions were higher than those of breast adenoma group;apoptosis-related gene SFRP2 mRNA expression in the lesions was lower than that of breast adenoma group whereas Smo and TPX2 mRNA expression were higher than those of breast adenoma group;invasion-related genes AEG-1 and HERC4 mRNA expression in the lesions were higher than those of breast adenoma group whereas HSPC238 and TET1 mRNA expression were lower than those of breast adenoma group;correlation analysis showed that the SWE parameter Emax level in breast cancer lesions was directly correlated with the proliferation, apoptosis and invasion activity of cancer cells. Conclusion: SWE parameter level in breast cancer tissue is significantly different from that in benign lesions, and the specific level can be used to determine the malignant degree of cancer cells.展开更多
