Objective To explore the relationship between ultrasonographic characteristics and promoting angiogenesis related genes in breast invasive ductal carcinoma.Methods A search was conducted in the PubMed database to identify genes related to promoting an-giogenesis in breast cancer.Protein-protein interaction networks(PPI)were constructed using the STRING database and Cytoscape soft-ware,and screen for key genes.A total of 38 female patients diagnosed with breast invasive ductal carcinoma from January 2022 to August 2023 were included in the study.The relationship between clinical and ultrasonographic characteristics of these patients and key genes was analyzed.Results A total of 10 key genes were screened.The expression levels of TGF-β1 and CXCL12 in patients aged＞50 years were higher than those in patients aged ≤50 years(P＜0.05).The expression level of IL-6 in patients with lymph node metastasis was higher than that in patients without lymph node metastasis(P＜0.05).The expression level of CCL2 in patients with color pixel percent-age(CPP)of ultra micro angiography(UMA)＞10％was higher than that in patients with CPP of UMA ≤10％(P＜0.05).The ex-pression level of Akt1 in patients with predominantly peripheral vascular distribution were higher than that in patients with central distribu-tion(P＜0.05).The expression levels of IL-6,TGF-β1,PEC AM1,CXCL8 and CXCL12 in patients with uneven contrast perfusion were higher than those in patients with even contrast perfusion(P＜0.05).The expression levels of TGF-β1,PEC AM1,FN1 and CX-CL12 in patients with contrast perfusion defect area＞1/2 were higher than those in patients with contrast perfusion defect area≤1/2(P＜0.05).There was a correlation among genes involved in regulating contrast perfusion uniformity and perfusion defect area,particu-larly the intersecting genes TGF-β1,PECAM1 and CXCL12(P＜0.05).Conclusion There is a correlation between the ultrasono-graphic characteristics of breast invasive ductal carcinoma and key genes related to promoting angiogenesis,which may provide a reference for individualized treatment of breast cancer.
