Analysis on the diagnostic value of ABUS combined with DBT in dense type of intra-mammary breast cancer / 中国医学装备

ABSTRACT

Objective:To explore the diagnostic value of automatic breast ultrasound imaging system(ABUS)combined with digital breast tomosynthesis(DBT)for dense type of intra-mammary breast cancer.Methods:A total of 96 patients with dense type of intra-mammary breast cancer who admitted to hospital were selected,and all patients completed ABUS and DBT examinations within 1 week before they underwent the invasive operations such as puncture and surgery.Taking pathological results as the gold standard,the diagnostic values of ABUS and DBT for dense type of intra-mammary breast cancer were analyzed.Results:A total of 96 lesions were detected out from 96 patients by pathological examination.Based on the pathological results as the gold standard,the sensitivity,specificity and area under curve(AUC)value of ROC of ABUS were respectively 77.32%,82.53%and 0.711(95%CI:0.635～0.792)in diagnosing dense type of intra-mammary breast cancer.The sensitivity,specificity and AUC value of DBT were respectively 81.59%,80.23%and 0.734(95%CI:0.612～0.776)in diagnosing that.The sensitivity,specificity and AUC of ABUS combined with DBT were respectively 89.38%,92.46%and 0.787(95%CI:0.659～0.824)in diagnosing that.Conclusion:ABUS combined with DBT is beneficial to improve the clinical detection rate of dense type of intra-mammary breast cancer,and reduce the missed diagnosis of tumor without company of calcification lesion.
