Screening breast ultrasound detects cancers missed on mammography in women with dense breasts

Screening breast ultrasound performed after mammography on women with greater than 50% breast density detects an additional 3.4 cancers or high risk lesions per one thousand woman screened, a detection rate just under that of screening mammography alone for women with less dense breasts, a new study shows. Screening mammography detects 4-5 cancers per thousand women screened.

The study, conducted in conjunction with seven Connecticut radiology practices, included 19,745 women who had dense breasts and "normal" mammograms. Sixty-seven cancers were found, said Dr. Sarah Steenbergen, lead author of the study, who is now at Yale University in New Haven, CT.

"Out of the available surgical reports, only one case had nodal involvement at the time of diagnosis. This suggests that the cancers are detected early and therefore we anticipate a survival benefit," Dr. Steenbergen said.

The study has been conducted over two years, "and we've seen an improvement in the sensitivity of screening breast ultrasound from 96.6% to 100% and in specificity from 94.0% to 96% from the first to the second year," she said.
This illustrates a learning curve, and "we anticipate that as the number of screening breast ultrasounds increase, physicians will be even better able to differentiate benign from malignant lesions," she said.

Recent legislation in Connecticut mandates reporting of breast density on mammograms and recommending follow up screening ultrasound for women with greater than 50% breast density, said Dr. Steenbergen.
The study was conducted, in part, to measure the outcome of this legislation and what we can hope to achieve with screening breast ultrasound, she said.

Dr. Steenbergen will present her study at the ARRS annual meeting on April 18 in Washington, DC.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
