Aunt Minnie (3/16, Ridley) reports, “Image analytics software can be used to determine which women with breast cancers that are positive for the estrogen receptor (ER) need chemotherapy and which ones have nonaggressive cancers that only require hormonal treatment,” research suggests. In a study published online Feb. 18 in Scientific Reports, researchers “used an image analytics algorithm to analyze dynamic contrast-enhanced MRI (DCE-MRI) breast studies.” The study authors discovered that “it had an 85% correlation rate with an assay test that is typically used to categorize risk in these cancers.”
MedPage Today (3/11, Bankhead) reported that research indicated “women with early breast cancer had similar, low recurrence rates with adjuvant radiotherapy limited to the tumor bed or irradiation of the entire breast.” Investigators found that “the 5-year local recurrence rates ranged from 0.5% to 1.1% and did not differ significantly in women who received partial or whole-breast irradiation (WBI), including a hybrid protocol that included a reduced radiation dose to the breast.” Additionally, “cosmesis, physician-reported adverse events, and patient-reported outcomes...did not differ across treatment groups in the 2,000-patient trial.” The findings were presented at the European Breast Cancer Conference.
Aunt Minnie (3/10, Yee) reports, “Ultrasound has an edge in sensitivity over digital breast tomosynthesis (DBT) as an accompaniment to standard 2D mammography in women with dense breast tissue,” research presented at the European Breast Conference and published online March 9 in the Journal of Clinical Oncology suggests. However, “tomosynthesis may still be the more promising modality for breast cancer screening even though ultrasound detects more cancers,” primarily “because tomosynthesis can be easily incorporated into standard 2D mammography protocols, while finding 50% of mammographically occult breast cancers.”
HealthImaging (3/10) reports that “an alternative digital full-field mammography quality assurance program has been cleared for use nationwide, according to an announcement from the FDA.” The “alternative standard” is “based on the American College of Radiology Digital Mammography Quality Control Manual.”
