Triple-negative breast cancers show marked clinical features
By Kate Madden Yee
CHICAGO - Women diagnosed with triple negative (TN) breast cancer -- in which the tumor is estrogen receptor-negative, progesterone receptor-negative, and HER2-negative -- tend to have fewer treatment options and worse prognoses than women with non-TN tumors. But certain characteristics and imaging features may help clinicians diagnose these tumors earlier, according to a presentation at the RSNA 2007 meeting.

US-based minimally invasive treatments prove feasible for uterine fibroids
By Shalmali Pal
When it comes to the ultrasound-based treatment of uterine fibroids, clinicians should target patients whose benign tumors are not too big or not too small, according to two new studies. Researchers from Italy found that that percutaneous sonography-guided radiofrequency thermal ablation (RFA) was particularly adept at shrinking medium-sized fibroids, while a Japanese team found that MR-guided focused ultrasound (MRgFUS) surgery was an optimal therapy option for fibroids with specific characteristics on preoperative imaging.
