Aunt Minnie (8/10, Casey) reports that “synthetic 2D mammograms received the thumbs up for breast cancer screening from researchers at the Hospital of the University of Pennsylvania...in” an “article published in Radiology.” The researchers “say the exams are good enough to replace conventional digital mammography studies as a complement to digital breast tomosynthesis (DBT).”
HealthDay (8/8, Reinberg) reports that research suggests “overweight and obese women who eat a Western-style diet may develop more dense breast tissue.” Researchers looked at data on approximately 3,500 women. The researchers “also rated the density of the women’s breast tissue as seen on a mammogram.” The investigators found that “the women were about 41 percent more likely to have denser breast tissue than women who ate a Mediterranean-type diet.” The findings were published Obstetrics and Gynecology.
Aunt Minnie (8/5) reports that research suggests “shear-wave elastography measurements of tumor stiffness can predict early on if breast cancer patients won’t respond to neoadjuvant chemotherapy, enabling clinicians to quickly switch to a different treatment strategy.” Investigators “found that those who ultimately responded to neoadjuvant chemotherapy had much greater reduction in tumor stiffness measurements after two cycles of treatment than nonresponders.” Aunt Minnie adds, “Using a defined tissue stiffness threshold cutoff value, shear-wave elastography would have yielded 72.9% sensitivity and 85.7% specificity for predicting treatment response, according to the” researchers. The findings were published in the Journal of Ultrasound in Medicine.
Aunt Minnie (8/1) reports a study published in the August issue of the American Journal of Roentgenology found that molecular breast imaging (MBI) can be an “effective option” for scanning women with dense breast tissue. Lead author Dr. Robin Shermis from ProMedica Breast Care in Toledo, Ohio, told AuntMinnie.com that MBI is “a very effective adjunct screening modality to mammography,” noting it is “easy to use, it’s inexpensive, and it’s safe.” 1,696 women with dense breasts and negative mammography results participated in the study. After undergoing screening with molecular breast imaging, “MBI detected 13 cancers that mammography didn’t identify; seven were in heterogeneously dense tissue and six were in extremely dense tissue. Eleven of the 13 cancers were invasive.” The authors also concluded “MBI also beat ultrasound when it came to incremental cancer detection and PPV for biopsy.”
