Diagnostic value of Doppler ultrasound parameters combined with MMP-11 in early breast cancer and benign breast diseases

Diagnostic value of Doppler ultrasound parameters combined with matrix metalloproteinase-11 (MMP-11) in early breast cancer and benign breast diseases were investigated. A total of 72 patients who underwent color Doppler ultrasound examination in Liaocheng Third People's Hospital from March 2015 to August 2018 were collected as research subjects, and the blood of 60 healthy subjects who underwent physical examinations was collected. The expression level of MMP-11 in serum of breast cancer patients was evaluated, and the diagnostic value of color Doppler ultrasound combined with MMP-11 in breast cancer was assessed. The diagnostic results of color Doppler ultrasound and the imaging characteristics of breast cancer patients were recorded. The results of biopsy and ultrasound were compared. The expression level of MMP-11 in serum of breast cancer patients was significantly higher than that of healthy subjects (P<0.05). The AUC of MMP-11 was 0.735, the sensitivity was 66.67%, and the specificity was 86.11%. Among the 72 patients, there were 41 patients diagnosed with breast cancer by serum MMP-11 examination, 38 patients diagnosed by ultrasound examination, 33 patients diagnosed by combined diagnosis, and 30 patients diagnosed by pathology biopsy. The pathological biopsy was used as the gold standard. The diagnostic efficacy of ultrasound combined with mammography examination was significantly better than the other two single examinations (P<0.050). In conclusion, Doppler ultrasound parameters combined with MMP-11 has a high diagnostic accordance rate in the diagnosis of breast cancer. At the same time, different diagnostic methods combined with the clinical manifestations of patients can improve the diagnostic accuracy, which is worthy of providing reference and advice for future clinical practice.
