HealthDay (3/21, Preidt) reports a new study suggests “women with breast symptoms at a regular cancer screening are more likely to develop breast cancer before their next screening.” Specifically, “compared to women with no symptoms, those with a lump had more than triple the risk for a breast cancer diagnosis before their next scheduled screening.” The findings were presented at the European Breast Cancer Conference in Barcelona, Spain.
Aunt Minnie (3/20, Yee) reports study published online March 19 in JAMA Internal Medicine found “women older than 75 received breast screening less often after they enrolled in an accountable care organization (ACO).” The change “was part of a general trend in which ACOs shifted cancer screening to conform with existing clinical guidelines,” and in addition to declining participation in breast screening for older women, “members of ACOs saw lower levels of prostate cancer screening, while colorectal cancer screening tended to shift toward those at highest risk of the disease,” the article says.
The Radiology Business Journal (3/16, Slachta) reported clinicians have found that “false positive rates are lower and cancer-detection rates higher when using digital breast tomosynthesis (DBT) for breast cancer detection and diagnosis,” according to a study to be presented at the American Roentgen Ray Society’s annual meeting from April 22-27. According to an ARRS release, “Rates of false positive breast cancer screening exams fell after complete integration of DBT into oncology practices.”
The Diagnostic Imaging (3/16) reported researchers from the Netherlands found that “screening performance in breast screening is dependent on risk category,” according to a study in the journal Radiology. The researchers “evaluated screening MR imaging and mammography for women who had an increased risk of breast cancer,” taking account of “risk category, age, recall for workup of screening-detected abnormalities, biopsy, and histopathologic diagnosis.” They “concluded that screening performance was dependent on risk category, with sensitivity lowest in carriers of the BRCA1 mutation.”
Aunt Minnie (3/14) reports that a study being presented at the upcoming American Roentgen Ray Society meeting shows that compared with mammography screening in women 50 and older, adding screening in women ages 40 to 49 finds 19.3 percent additional cancers. By adding the women ages 40 to 49 to the screening population of those 50 and older, “the overall callback rate increased 1.5%, the biopsy rate increased 0.1%, and 19.3% more cancers were detected,” according to researchers.
