European Study Results Published in Lancet Oncology Conclude that Low Dose 3D MAMMOGRAPHY™ Exams Detect More Invasive Cancers than 2D Mammography Alone

--Tomosynthesis Screening Combined with Either Traditional 2D or Hologic’s C-View™ 2D Provides Comparable Results--
MARLBOROUGH, Mass., August 9, 2016 -- Hologic Inc. (Nasdaq: HOLX) announced today that study results published online in advance of print by Lancet Oncology conclude that Low Dose 3D MAMMOGRAPHY™ exams with C-View™ software are comparable to traditional breast tomosynthesis screening exams in detecting more invasive breast cancers than 2D mammography alone.[i]

While there have been a multitude of studies that have shown that generated 2D images provide equivalent performance to conventional 2D images as part of the tomosynthesis exam, this is the first prospective study publishing final results confirming the benefit each screening modality has on invasive cancer detection rates versus 2D mammography alone.

Hologic’s Low Dose 3D MAMMOGRAPHY™ exam with C-View™ software was created for physicians and patients seeking a low-dose screening option with the same benefits of 3D MAMMOGRAPHY™ exams. With C-View™ software, a 2D image is generated using the tomosynthesis data acquired during the mammography exam, eliminating the need for additional 2D exposures and as a result, decreasing the radiation dose and compression time.

"C-View™ software allows us to lower the patient radiation does of the market-leading Genius™ 3D MAMMOGRAPHY™ exam even further below the established mammography dose guidelines,” said Pete Valenti, Hologic's Division President, Breast and Skeletal Health Solutions. “We’ve received very positive feedback from customers who have embraced the technology, and this prospective study further confirms that Genius™ 3D MAMMOGRAPHY™ exams maintain the same outstanding performance when coupled with C-View™ software. Beyond that, it's another proof point that tomosynthesis, specifically the Genius™ exam, is the best choice for breast cancer screening."

The population-based screening study, led by Daniela Bernardi, MD, Director of the Mammography Screening Program at the Trentino Health Authority in Trento, Italy, analyzed the results of mammography exams for 9,677 women, all of whom were asymptomatic and over the age of 49. Breast tomosynthesis screening exams with conventional 2D detected 35 percent more cancers and 76 percent more invasive cancers when compared to 2D mammography alone. Furthermore, the combination of breast tomosynthesis with C-View™ 2D images detected 40 percent more cancers overall and 83 percent more invasive cancers than 2D mammography alone.1 Recall positive predictive value (PPV), the probability that patients with positive screening results truly have cancer, was higher for both cohorts compared to 2D mammography alone.1

“We’re very pleased that this prospective study was consistent with previous analyses of the impact of tomosynthesis with synthesized [generated] 2D images on invasive cancer detection rates,” said Dr. Bernardi. “The body of literature as a whole strongly suggests that C-View™ 2D images provide an equivalent contribution as standard 2D mammography, and are an acceptable replacement for traditional 2D exposures as part of a tomosynthesis exam. While some physicians may choose to reduce the number of views to achieve low dose, my colleagues and I view the current lower-dose approach of synthesized 2D images with tomosynthesis more appropriate for breast cancer screening.”

This study was conducted on Hologic’s Selenia® Dimensions® mammography system using the Company’s C-View™ software and as such, the results are not applicable to other manufacturers’ technology.2

Hologic’s Low Dose 3D MAMMOGRAPHY™ exam with C-View™ software is CE marked, FDA approved and is commercially available in the U.S. and Europe. Genius™ 3D MAMMOGRAPHY™ exams are only available on the Hologic Selenia® Dimensions® system.
