HealthImaging (4/6, Hocter) reports that research indicated that “follow-up visits from trained community health workers known as ‘promotoras’ have been shown to improve breast cancer screening rates among Latino women.” Investigators found that “promotora visits improved the rate of screening mammography by more than 8 percent when compared to normal care strategies.” The findings were published in Cancer Epidemiology.
Aunt Minnie (4/6) reports an analysis of studies showed that adding digital breast tomosynthesis to full-field digital mammography yields a “higher overall cancer detection rate that was statistically significant.” One author of the analysis, Julie Glanville from the University of York in the UK, said the review was novel in examining DBT versus FFDM for screening, rather than diagnosis. Glanville also said the amount of data was significant, adding, “Very often we are analyzing one or two small studies and it is difficult to draw conclusions, but that was not the case with this review. As far as we are aware, this is the first systematic review of tomosynthesis to be published.”
Aunt Minnie (4/6) reports a study conducted since 2008 by the Ain Shams University in Cairo has found that risk for breast cancer among Egyptian women studied increased as breast density classification increased. Researchers split “136,833 women ranging in age from 40 to 65” into four groups according to ACR mammographic density guidelines: “class A, almost entirely fatty; class B, scattered fibroglandular tissue; class C, heterogeneously dense; and class D, extremely dense.” According to lead researcher Dr. Nivine Chalabi, there was a “statistically highly significant” rise in risk between class A and class B, as well as between any two ascending groups.
According to Diagnostic Imaging (4/4), a new study published in Radiology found that “MRI may help predict recurrence-free survival (RFS) in women with breast cancer, even in the presence of pathologic complete response (PCR) and residual cancer burden (RCB) class.”
Aunt Minnie (3/31, Yee) reports, “Overdiagnosis has emerged as a major flash point in the debate over breast screening.” Nevertheless, “breast imagers can defuse the overdiagnosis argument with five steps that use the power of advanced imaging to make screening more precise and less invasive,” research published online March 23 in Academic Radiology suggests. In the study, researchers “offered ideas that range from adjusting biopsy protocols and exploring new screening technologies to tapping into the power of radiomics, or assessing quantitative features in images.” Other ideas “include using imaging biomarkers to track malignancy and tailoring treatment to individual patients.”
