| ABSTRACT |
|
Purpose : Triple-negative breast cancer is characterized as a cancer with a high malignancy potential and a poor
prognosis. Therefore, early detection of this subtype of breast cancer is vital. In this paper, we describe ultrasound
findings of triple-negative breast cancer in our hospital cases and investigate the specific features of this subtype.
Methods : From June 2010 to December 2010, ultrasound findings of 74 patients with breast cancer were
retrospectively reviewed. Ultrasound findings were reviewed according to the BI-RADs. Ultrasound findings were
classified as masses, low echoic area, distortions, and calcifications. Noted features included shapes, patterns of
internal echoes, posterior echoes, vascularity. Chi-squared tests were used for statistical analysis.
Results : Round shape was found in 20 patients (54.1%) in TNBC. And microlobulated margin was found in 16
patients (43.2%) in TNBC. Also echogenic halo and posterior acoustic enhancement was found in 34 patients
(91.9%), 12 patients (32.4%) respectively. Round shape was more associated with TNBC than other tumor types
(p=0.018). Also posterior acoustic enhancement was associated with TNBC than other tumor type (p=0.022).
Conclusion : Ultrasound imaging together revealed that the ultrasound features of triple negative breast cancer
include a round mass, with posterior echogenic enhancement. |
