RESUMO
Objective To investigate the ultrasonic features of triple-negative breast cancer (TN-BC).Methods Ultrasonographic findings of 299 patients with pathologically confirmed breast cancer were analyzed retrospectively.Patients were divided into TNBC group (46 cases) and non-triple-negative breast cancer(NTNBC) group (253 cases) according to the expression of estrogen receptor (ER),progesterone receptor (PR),and human epidermal growth factor receptor 2 (HER2) that were determined with immunohistochemical staining.Each patient was ultrasonically analyzed.Results The ultrasonic images showed that TNBC group had a greater proportion in the mass with regular shape,clear boundary,or microlobulated relative to NTNBC group (P ＜ 0.01).Calcification was significantly less in TNBC than NTNBC (P ＜0.01).Eight (17.3％)of 46 Cases of TNBC had BI-RADS sonographic features that favored the diagnosis of a benign condition.Conclusions Some of sonographic criteria for TNBC are more likely to be associated with benign lesions,ultrasound-guided biopsy should be recommended for such lesions.
RESUMO
Objective To explore the value of elastography score and strain rate ratio in the diagnosis of small breast malignant focus. Methods We retrospectively analyzed 22 patients with breast small malignant foci less than 10 mm. Ultrasound characteristics were summed up in breast small cancer. Results On elastogram, 2 patients scored 3, 14 scored 4 and 6 scored 5.The average strain rate ratio of all foci was 4.76, and there was correlation between it and elastography scores. Conclusion Ultrasonic elastography has important value in the diagnosis of breast small cancer.
