Hologic : Peer-Reviewed Study Concludes Hologic’s C-View™ Software Maintains Clinical Performance of Genius™ 3D MAMMOGRAPHY™ Exam at a Lower Patient Radiation Dose

MARLBOROUGH, Mass., August 17, 2016 -- Hologic Inc. (Nasdaq: HOLX) announced today that a study by University of Pennsylvania researchers, published online in advance of print by Radiology, shows that Low Dose 3D MAMMOGRAPHY™ exams with C-View™ software are comparable to traditional Genius™ 3D MAMMOGRAPHY™ exams, with similar overall and invasive breast cancer detection, as well as recall rates.[i]

Hologic's C-View™ software was created for physicians and patients seeking a low-dose screening option with the same clinical benefits as the Genius™ exam. 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. As a result, the radiation dose is lowered to one similar to conventional mammography alone, and the exam's compression time is reduced.

This is the first major U.S. study that compares the performance of Low Dose 3D MAMMOGRAPHY™ exams to traditional Genius™ exams. Lancet Oncology previously published findings of a European study with similar conclusions.[ii]

'We are pleased to see this Radiology paper confirm that Low Dose 3D MAMMOGRAPHY™ exams offer comparable clinical performance to our top-rated Genius™ 3D MAMMOGRAPHY™ exams, but at a dose even further below the established dose guidelines and with a faster exam time that makes it more comfortable for patients,' said Pete Valenti, Hologic's Division President, Breast and Skeletal Health Solutions. 'This study reaffirms the efficacy of C-View™ software, and further underscores the value of 3D MAMMOGRAPHY™ exams for breast cancer screening.'

The study, led by Dr. Emily Conant, MD, from the Breast Imaging Division, Department of Radiology, Hospital of the University of Pennsylvania, compared recall rates, biopsy rates, cancer detection rates and radiation dose for 15,571 women who received a traditional Genius™ exam (digital mammography/DBT) and 5,366 women who were screened with Hologic's Low Dose 3D MAMMOGRAPHY™ exam (synthesized 2D/DBT). Both screening methods had comparable performance, but the associated dose was significantly reduced by 39 percent with the adoption of C-View™ software. Furthermore, the low-dose screening option demonstrated an increase in the probability of a patient's biopsy finding cancer, in comparison to traditional Genius™ exams.

'In our study, the replacement of standard 2D mammography with C-View™ 2D images in combination with a tomosynthesis exam resulted in equivalent cancer detection,' said Dr. Conant, senior author of the study. 'Additionally, using synthetic 2D images resulted in a significant reduction in radiation dose while maintaining the reduction in recalls from 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.

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. The Genius™ 3D MAMMOGRAPHY™ exam is only available on the Hologic Selenia Dimensions system.
