JAMA study finds mixed results for screening mammography: Who's affected?

April 2, 2013

Shaun Lillard, Imaging Performance Partnership

A new study provides supporting evidence for the United States Preventive Services Task Force’s (USPSTF) somewhat controversial 2009 recommendations for screening mammography in women over 50, but does not reinforce task force guidelines for women ages 40-49.  

Published in the latest issue of Journal of the American Medical Association (JAMA), the article features new results from a study of screening mammography outcomes based on frequency, breast density, and postmenopausal hormone therapy.

Study shows lingering harms of breast cancer false positives

March 25, 2013

Stephanie Krent, Imaging Performance Partnership

The debate over mammography is well-known to imaging leaders. Some critics believe our country over-screens for breast cancer, which may cause physical, psychological, and financial harms to patients with false positive findings. Yet many others argue that those harms are significantly outweighed by the tool’s proven ability to save lives and initiate cancer earlier when it can be less invasive and expensive.

A new study released this month from the Annals of Family Medicine suggests that women with false positive findings suffer harm more seriously, and for longer periods of time, than initially thought.

In case you missed it: DBT shows improvement in screening setting

February 6, 2013

Shaun Lillard, Imaging Performance Partnership

My colleagues at Technology Insights recently posted a blog on Digital Breast Tomosynthesis (DBT) and I wanted to share it with you. The post highlights results from a large-scale screening trial with further clinical evidence of DBT’s ability to detect cancers over standard digital mammography when used for screening.

Digital breast tomosynthesis significantly outperforms diagnostic mammography in study

January 28, 2013

Shaun Lillard, Imaging Performance Partnership

A study published in the January issue of Radiology provides clinical evidence that digital breast tomosynthesis (DBT) enables greater diagnostic accuracy than standard diagnostic mammography. Led by Dr. Margarita Zuley, researchers from the University of Pittsburgh compared the findings of eight breast imaging radiologists who had retroactively reviewed 217 lesions in 182 patients.

The study found that “tomosynthesis significantly improved diagnostic accuracy for noncalcified lesions compared with supplemental mammographic views.” There is hope that evidence such as this will reduce unnecessary biopsies and lower downstream costs as more sites implement DBT.

Initial results for screening ultrasonography in Connecticut breast density act

October 22, 2012

Shaun Lillard, Imaging Performance Partnership

A study in the October issue of Radiology has published some of the earliest findings on the effects of breast density legislation for a state’s patient population.

Aiming to “determine performance and utilization of screening breast ultrasonography (US) in women with dense breast tissue who underwent additional screening breast US in the 1st year since implementation of Connecticut Public Act 09-41,” the study was undertaken by six physicians at the Yale University School of Medicine.

A breast density bill passed in California; is your state next?

October 2, 2012

Stephanie Krent, Imaging Performance Partnership

Second time’s a charm for California senator Joe Simitian; just one year after his breast density legislation was vetoed, Governor Brown has signed an updated version, S.B. 1538 into law.

The senator (D-Palo Alto) released a statement praising Governor Brown’s "willingness to listen and work with us on this issue over the past year" and describing his own feelings as “tremendously thankful.”

In case you missed it: A full breast scan in one exposure

September 24, 2012

Robin Brand, Imaging Performance Partnership

Our colleagues at Technology Insights recently blogged on single-shot spectral mammography, a tool that may hold the potential to disrupt traditional breast imaging. The Partnership continues to monitor the latest on this technology and breast imaging more broadly.

Our most recent research in the terrain will be released in October, providing members with an overview of the current market for breast imaging, including the latest in technologies and in operational trends.

European breast cancer study finds substantial screening benefits

September 17, 2012

Shaun Lillard, Imaging Performance Partnership

In a sharp rebuke of skeptical studies and reports published over the past few months, the Journal of Medical Screening released a review of European studies on service screening for breast cancer and found a significant mortality benefit.

Researchers concluded that the primary benefit was breast cancer mortality reduction and the principal drawback was over-diagnosis of breast cancer and false-positive screening tests that often result in unnecessary biopsies.
