Automated Whole Breast Ultrasound

Mary W Yamashita, MD

The SoftVue™ is a whole breast ultrasound system with an automated scanning curvilinear ring-array transducer that employs UST. It is currently cleared under FDA 510(k) K123209 and K142517 for use as both a B-mode ultrasonic breast imaging system and color imaging of transmission data (sound speed and attenuation). SoftVue™ is not intended to be used as a replacement for screening mammography.

SoftVue uses non-ionizing ultrasound energy to generate tomographic image volumes of the whole breast. While the patient lays prone on a padded table with one breast comfortably submerged in a bath of warm water, a ring-shaped transducer, 22 cm in diameter, encircles the breast and pulses low-frequency sound waves through the water and into the breast tissue. More than 2000 elements in the curvilinear transducer's 360 degree array emit and receive ultrasound signals to analyze echoes from the breast anatomy in all directions, from the chest wall to the nipple. Not only does SoftVue capture data from the reflection of the sound waves off of tissue boundaries and structures within the breast, but because the transducer surrounds the whole breast, SoftVue also captures signals that are transmitted through the breast. This additional transmission data enhances the visualization of the anatomic structure of the breast tissue and is not currently available in any other commercially marketed breast ultrasound device.

This prospective, multicenter, multi-arm, clinical case collection program is IRB-approved and will be conducted in compliance with Good Clinical Practice, the Declaration of Helsinki and all applicable regulatory requirements. Arm 1 aims to collectively enroll up to 17,500 women at a total of up to 8 clinical sites. The design of this protocol is strictly limited to case collection; all investigational and statistical plans for future analyses will be prepared and registered separately, if they are applicable to the requirements of FDAAA 801.

Arm 1 is limited to the cohort of asymptomatic women, with heterogeneously or extremely dense breast parenchyma (BI-RADS breast composition category c or d). Matched triads of 2D digital mammography (FFDM), 3D digital mammography (DBT), and SoftVue automated whole breast ultrasound (SV)exams, from the same patient, with demographic information and clinical outcome data, will be collected during the same screening imaging episode. Ultrasound characteristics for all types of lesions, whether they are benign or malignant, will be collected, as well as objective and subjective breast density composition data.

The exams and clinical data accumulated in this prospective case collection (PCC) protocol will populate a database from which future investigations may be designed for peer reviewed publication, development of user training curriculums, building teaching case, and creating new marketing materials for SoftVue.A subset of exams will be sampled from Arm 1 for use in ROC Reader Study (protocol DMT-2015.002), which will be separately registered and is designed to evaluate the safety and efficacy of a new screening indication for use of SoftVue™ as an adjunct to screening mammography. The results of this ROC Reader Study will be submitted to the FDA for their consideration of a PMA application for SoftVue.

Conventional digital mammography.

Alfonso Frigerio, Dr

Preliminary results from prospective screening trials show that Digital Breast Tomosynthesis (DBT) is more sensitive and more specific than conventional digital mammography (DM). However, large randomised controlled trials (RCTs) are needed to confirm these promising results. Furthermore, potential side effects of DBT in the screening setting have to be properly evaluated. In particular, the major concern is about overdiagnosis and its consequences; overdiagnosis refers to the detection of cancers at screening, which would not have become clinically apparent in the woman's lifetime.

This RCT was designed to compare benefits and harms of DBT in a population-based screening program with conventional DM. The primary outcome parameter will be the difference between the two tests in rates of advanced cancers detected at the subsequent round and interval cancers (within the first two years after the study screening round). Secondary outcomes measures will be diagnostic performance indicators for organised breast screening (i.e, cancer detection rate, recall rate, false positive rate, positive predictive value), parameters used in cost-effectiveness analysis, pathologic and biological characteristics of screen-detected cancers.

Design of the study This trial will involve several hospital centres within the organised breast screening in the Italian region of Piedmont.

An invitation letter to participate in a randomised screening trial comparing DBT versus DM will be mailed to all women, 46-68 years old, living in the Piedmont Region, and eligible for invitation to the regional mammography screening program. Women who attend the centres for screening and consent to the study will be randomly allocated either to DBT or DM arm.

Women in the DM arm will be screened with bilateral, two-views digital mammography examination. Women in the DBT arm will be screened with the bilateral two-views combo mode (DM and DBT images acquired in a single compression). In both screening arms, examinations will be independently read by two expert screening radiologists. In the DBT arm, each reading will be randomly allocated (on a per-case basis) to one of these three modes: DM plus DBT (DBT is read only after initial DM interpretation), DBT plus DM (DM is read only after DBT interpretation) and "concurrent mode" (both DBT and DM are read simultaneously).

In both screening arms, participants will be recalled for further examination if indicated by at least one radiologist (without consensus or arbitration). At the subsequent round all participants will be invited to DM only. Interval cancers and advanced cancers screen-detected at the next round will be recorded. Pathological and biological parameters of screen-detected cancers (e.g, stage, grading, hormone receptors, HER2) in both screening arms will be measured to investigate overdiagnosis.

With a sample size of 23,000 and 69,000 women in the DBT and DM arm respectively, the investigators will be able to observe a significant decrease in interval cancers and advanced cancers rate of at least 50% (power 80%, two tails). The collected data will be also used to perform analyses on radiological work-flow and workload, and cost-outcome and cost-effectiveness.

The aim of this recruitment plan (ADAPT-SCR) is to collect image and other data on both digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM) from asymptomatic women undergoing screening mammography.

ADAPT program consists of 2 recruitment plans (ADAPT-SCR and ADAPT-BX) followed by an off-line read of the images and data collected (ADAPT-BIE). This study involves the comparison of two devices that can identify abnormalities in routine breast screening and diagnostic mammography. Mammography is usually done with full-field digital mammography (FFDM), which takes flat, two-dimensional X-ray images of the breast. Doctors use the two-dimensional images to look for cancers and other abnormal tissue. The purpose of this study is to learn more about the accuracy of full-field digital mammography devices and a new mammography device called digital breast tomosynthesis (DBT). DBT is similar to full-field digital mammography, but can also move around the breast to get X-ray images from different angles, which provides a three-dimensional view that doctors can use to look for cancers and abnormal tissue. Subjects will undergo routine imaging with FFDM and will also have a DBT performed. They will continue with their standard of care treatment as would occur outside of the study. Based on the results of the FFDM and DBT, the subject's status will be followed-up with routing imaging at approximately 1 year (10-16 months). If the doctor recommends biopsy based on the FFDM or DBT, information about the biopsy and cancer determination results will be collected. Being in this study does not require subjects to have a biopsy that was not recommended by the doctor for normal medical care.
