Abstract Objective: To explore the value of real-time tissue ultrasound elastography (RTE) in the diagnosis of breast cancer. Methods: From July 2019 to July 2022,105 patients with breast masses in our hospital with 170 lesions were examined by RTE to compare the differences of RTE parameters between benign and malignant lesions,and RTE parameters of malignant lesions with different clinicopathological characteristics,the values of elasticity score,entirety strain rate ratio (ESR),local strain rate ratio (LSR) and blue area ratio (AREA%) in diagnosing benign and malignant lesions were also analyzed. Results: 170 lesions were diagnosed by pathology,including 70 benign lesions and 100malignant lesions.Compared with benign lesions,the ESR,LSR and AREA% of malignant lesions were (3.05 ± 0.88),(46.69 ± 20.28) and (74.30 ± 28.31)%,which were significantly higher(P<0.05); compared with benign lesions,the proportion of elasticity score ≥ 3 in malignant lesions was 67.86%,which was higher than that in benign lesions (P<0.05); there was no significant difference in elastic score,ESR,LSR and AREA% between breast fibroma and other benign lesions (P>0.05); there was no significant difference in elastic score,ESR,LSR and AREA% among patients with different age,lesion size and pathological type (P>0.05); ESR,LSR and AREA% in TNM stage Ⅲ~Ⅳ were significantly higher than those in stage Ⅰ~Ⅱ (P<0.05); the area under the ROC curve of elasticity score,ESR,LSR,and AREA%to judge benign and malignant lesions were 0.676(95%CI:0.593~0.759),0.746 (95%CI:0.652~0.804),0.905 (95%CI:0.753~0.901) and 0.794 (95%CI:0.705~0.883),P<0.05. Conclusion: RTE parameters have a certain application value in the diagnosis of breast cancer,which can provide objective diagnostic indicators and is worth clinical application.
