3D Mammography finds more invasive cancers and reduces unnecessary recalls

25.06.2014

Donna Plecha, M.D., of University Hospitals Case Medical Center co-authored largest 3D study to date of nearly half a million women, published in JAMA

3D Mammography finds significantly more invasive cancers and reduces unnecessary recalls, according to a large, retrospective study published in June 25 issue of the Journal of the American Medical Association (JAMA). The study features data from University Hospitals Case Medical Center Seidman Cancer Center.

The study, the largest of its kind, focused on the impact of 3D mammography at a diverse range of sites across the U.S, looking at nearly half a million mammograms at 13 sites.

Key Findings:

  • 41% increase in invasive cancer detected with 3D mammography
  • 15% decrease in unnecessary recalls for false alarms
  • A 29% increase in the detection of all breast cancers

"This study confirms what we already know: 3D mammography finds more of the invasive, harmful cancers we want found and saves women the anxiety and cost of having additional exams for what turns out to be a false alarm," said the study's co-author Donna Plecha, MD, Director of Breast Imaging at UH Case Medical Center. "We already knew that breast screening saves lives and this study provides us with firm data that 3D mammography is a better test for detecting breast cancer early when it is treatable."

Hologic 3D mammography (breast tomosynthesis) was used exclusively in the study, as they are the only FDA-approved 3D mammography manufacturer. University Hospitals Case Medical Center was involved in the initial research on tomosynthesis and has offered 3D mammography since 2011.

The system combines advanced digital mammography and tomosynthesis-generated images to provide a more detailed, highly focused picture of the breast. These images are then used to produce a series of one-millimeter thick slices that can be viewed as a 3D reconstruction of the breast. Women see little difference between a conventional 2D mammogram and a 3D mammogram. The exam takes just a few seconds longer and the positioning is the same. The real difference is in the information available to the doctor.

The technology gives radiologists the ability to identify and characterize individual breast structures and clearly see features which might be obscured in a traditional 2D mammogram by overlapping normal breast anatomy that may mimic or mask a tumor. Dense tissue and overlapping tissue structures may lead to false positive or false negative results with standard mammography.

Breast cancer is a significant health problem and statistics indicate that one in eight women will develop the disease in her lifetime. The stage at which the cancer is discovered influences a woman's chance of survival and annual mammography after the age of 40 enables physicians to identify the smallest abnormalities. In fact, when breast cancer is detected early and confined to the breast, the five-year survival rate is 97 percent.

"Breast cancers caught in the initial stages by mammography are more likely to be cured and are less likely to require chemotherapy or as extensive surgery," said Dr. Plecha, who is also Assistant Professor at Case Western Reserve University School of Medicine. "This study shows that 3D mammography is a more effective screening tool, and we must make it accessible to all women."

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
