Architectural Distortion May Be Less Likely To Signal Malignancy When Detected On Screening Mammography

Friday, December 18, 2015

HealthImaging (12/18, Pearson) reports that “architectural distortion, the non-mass but potentially ominous clinical feature observed in many breast imaging procedures, is less likely to signal malignancy when it’s detected on screening mammography rather than diagnostic mammography or when it doesn’t correlate with a subsequent targeted ultrasound exam.” The study, which was published in the December issue of the American Journal of Roentgenology, “placed the positive predictive value of architectural distortion for malignancy at 74.5 percent.” 

Multiple Breast Lesions Should Be Separately Assessed During Supplemental Screening Breast Ultrasound, Researchers Say

Thursday, December 17, 2015

According to Diagnostic Imaging (12/18), a study published in the journal Radiology suggests that “multiple breast lesions should be separately assessed during supplemental screening breast ultrasound (US), to reduce the number of missed cancers.” In the 230-patient study, investigators “concluded that when radiologists are viewing supplemental screening breast ultrasounds, ‘close attention should be paid to the presence of a margin that is not circumscribed, and multiple lesions should be separately assessed to reduce the number of missed breast cancers.’” 

MBI May Find Occult Breast Cancers That Could Have Been Missed After Years Of Screening

Thursday, December 17, 2015

Aunt Minnie (12/18, Yee) reports that molecular breast imaging (MBI) appears to be the “unsung hero in breast cancer detection for women with dense tissue.” In a study presented at the RSNA 2015 meeting, researchers pointed out that MBI “finds occult cancers that could have been missed after years of screening.” 

Early Detection of Breast Cancer Improves as Screening Tests Evolve

Tuesday, December 15, 2015
New approaches that safely screen women for breast cancer are being investigated in clinical trials and put into practice around the country. No matter what your level of risk for this cancer, it’s worth knowing about your options and promising new technologies. SBI President, Elizabeth Morris, MD, FSBI, discusses the enhancements to digital mammograms that are under way for women at average, increased, or high risk for breast cancer, and explains how Memorial Sloan Kettering in New York, NY, is implementing the new developments. 

Smoking May Increase Late Effects Of Radiation For Breast Cancer

Tuesday, December 15, 2015

Medscape (12/15, Osterweil) reports that “the risks for late lung cancer and ischemic heart disease among women who undergo irradiation for breast cancer are both reassuringly low, unless the patient is a smoker who just can’t kick the habit, said investigators from the Early Breast Cancer Trialists’ Collaborative Group.” The findings were presented at the San Antonio Breast Cancer Symposium. Carolyn Taylor, MD, said, “In our data, the main risks of breast cancer radiotherapy were cardiac mortality and lung cancer, and in nonsmokers, even taking those two risks together, the overall absolute risk was well under 1%, and that’s good news for many women.” However, Dr. Taylor said, “for one specific group of women – that is, long-term smokers who continue to smoke after their radiotherapy – the [absolute] risk of lung cancer may be a few percent, and that’s because the risk of lung cancer is 20 times greater in a smoker than in a nonsmoker.”
