A Clinical Study to Evaluate Somo•v and Digital Mammography Together as a Breast Cancer Screening Method, Compared to Digital Mammography Alone, in Women With Dense Breasts.
A Clinical Study to Evaluate Somo•v and Digital Mammography Together as a Breast Cancer Screening Method, Compared to Digital Mammography Alone, in Women With Dense Breasts.
Hypothesis: A higher sensitivity to breast cancer detection can be achieved in women with
 dense breast tissue by performing and reviewing results of Automated Breast Ultrasound (ABUS)
 and Digital X-Ray Mammography (XRM) together as part of routine screening compared to
 performing and reviewing results of XRM alone.

 Primary Objective: For the cohort of asymptomatic women who have dense breast tissue,
 calculate the sensitivity of Digital X-Ray Mammography (XRM) and ABUS together as a breast
 cancer screening modality and compare it to that of XRM alone.

 Secondary Objective: For the cohort of asymptomatic women who have dense breast tissue,
 evaluate the specificity of XRM and ABUS together compared to that of XRM alone; Calculate
 the negative predictive value (NPV) and positive predictive value (PPV) for XRM and ABUS.

 Endpoint: Breast cancers detected by radiologists in the clinical screening setting and
 confirmed by pathology.

 Study Design: This is a prospective matched-pair clinical study enrolling more than 20,000
 women with parenchymal density > 50% on digital x-ray mammography (XRM). Participants will
 receive ABUS as an adjunct to XRM. Any abnormal findings, from either XRM or ABUS, will
 receive appropriate management action consistent with accepted medical standards of care. All
 evaluation results, diagnosis and treatment outcomes will be recorded. Participants will be
 followed for one year and those who are not diagnosed with breast cancer at enrollment or
 during the follow-up interval must undergo an annual mammogram at study completion, the
 outcome of which will be recorded.
This is a study to determine if having somo٠v™ (U-Systems, Inc.) Automated Breast Ultrasound
 (ABUS) done together with a routine screening mammogram, is more sensitive to detecting
 breast cancer in women with dense breast tissue than getting a routine screening mammogram
 without ABUS. Potential study volunteers will be recruited at participating breast centers
 from the cohort of asymptomatic women who are scheduled to undergo routine screening
 mammography.

 Breast cancer is one of the most commonly diagnosed cancers in American women with an
 estimated 210,000 new cases diagnosed in 2007. Death rates in women with breast cancer are
 much lower when the cancer is detected at an early stage, and less intense forms of treatment
 can be used at early stages when cancerous lesions are the smallest. It is for this reason
 that annual routine mammograms are recommended by the American Cancer Society for women 40
 years of age and older and are the current standard of care for breast cancer screening.

 One thing that is known to interfere with the early detection of breast cancer with
 mammograms is a woman's breast density. Women under age 50 tend to have more density in their
 breasts than women who are older, but density may be present in women of all ages and is
 estimated to exist in 40% to 60% of all women who have mammograms. Women who have more
 fibrous connective and glandular tissue than fatty tissue in their breasts have more breast
 density.

 Breast density can make breast cancer difficult for a radiologist to see on a mammogram.
 Also, research has shown that women who have dense breast tissue are more likely to develop
 breast cancer in their lifetime than women who do not have dense breast tissue. Automated
 Breast Ultrasound (ABUS) is a breast imaging technology which is less affected by a woman's
 breast density, and is currently FDA approved for use by doctors and sonographers as an
 adjunct to mammography. ABUS is most commonly used in the diagnostic setting, when a woman
 has a known breast abnormality or symptom.

 This study will try to determine if ABUS can be a clinically beneficial element of routine
 breast screening in women who do not have any known abnormalities or symptoms, but do have
 dense breast tissue which could impact the accuracy of their yearly mammograms. Unlike
 mammography, ABUS does not use radiation. ABUS uses sound waves at a safe frequency to create
 pictures of the internal breast tissue. Ultrasound has been shown to find cancer not visible
 with mammography in women with dense breasts. The ABUS used in this study automatically scans
 the breast and may help detect cancers in dense tissue.

 All women who volunteer to participate in this study and who also meet the study requirements
 will receive ABUS in addition to their routine screening mammogram. The outcome of this
 screening will be recorded and followed for up to one year. Study participation will be
 finished at the completion of the next annual routine mammogram, or the diagnosis of breast
 cancer, whichever comes first.

 More than 50,000 women will be invited nationwide to provide informed consent and be screened
 for eligibility to participate. More than 20,000 women will meet the primary inclusion
 requirement of having > 50% dense breast tissue and will be enrolled in this study.

 Volunteers who decide to participate in this study must agree to the following:

 1. To have all routine standard care that is recommended by the study doctor, which may
 include diagnostic procedures like additional imaging or a biopsy, OR, if the results of
 screening (ABUS and XRM) are negative (normal or benign), agree to complete an annual
 routine screening mammogram one year from now and notify the study doctor if any breast
 changes or symptoms develop during this year.

 2. To be contacted by the study doctor, or one of the study staff members, if the
 recommended follow-up procedures are incomplete or if the volunteer does not return to
 the clinic in one year for an annual routine screening mammogram.

 3. To have an Automated Breast Ultrasound (ABUS), if the screening mammogram indicates
 dense breast tissue. ABUS will require the patient to lay comfortably on her back for
 approximately 10 minutes while the ultrasound is being performed. The study includes as
 many as three ultrasound scans of each breast, each scan lasting one minute. Unlike a
 mammogram, ABUS does not involve any mammography-like compression. Instead, the breast
 will be lightly pressed against the patient's body during the scan. If the mammogram
 shows that the breast tissue is not dense, the volunteer will not be eligible for
 further participation in the study and will not undergo an ABUS. The participant will
 still receive the same standard care and treatment she would normally receive.

 4. To complete a Study Participant Questionnaire and allow the study doctor to collect the
 following information from the medical records: breast health history, cancer treatment
 history, mammogram results, ABUS results, results of biopsy or aspiration, diagnosis and
 the outcome of follow-up mammogram one year later. Information, like name, date of birth
 and medical record number will be removed by the study doctor and/or clinic staff before
 these data are reported and analyzed.

 Participating in this study will take approximately 30 minutes in addition to the time a
 participant would normally spend in the office. This time will be spent learning about the
 study, providing informed consent and receiving ABUS. In order for the study doctors to
 gather data on the accuracy of mammography and ABUS, they will need to collect the
 mammography and ABUS results, as well as results from any other breast evaluations,
 procedures or testing performed for the next year, until the completion of an annual routine
 mammogram, the results of which will also be recorded.

 There are no known, harmful effects of breast ultrasound, although the procedure itself may
 be uncomfortable for women with breasts which are tender or sensitive to gentle pressure. If
 an abnormality is seen on the ABUS examination or on the mammogram, the study doctor may
 recommend additional tests, which are the standard of care and might include a biopsy. If any
 potential abnormalities are observed from the ABUS that are not seen on the standard
 mammogram, the participant and the study doctor will be informed and any testing that may be
 ordered as a result of the abnormal ABUS will be the same standard tests that would be
 ordered for an abnormal mammogram.Other risks of participating in the study include:

 1. Unknown risks. There may be risks or side effects which are unknown at this time and
 participation in the study may involve additional risks that are currently unknown.

 2. Loss of confidentiality. Just as with other medical information from routine medical
 care, all study related information will be kept as confidential as possible. Study
 information will be kept in locked files and in databases with password protected
 access. Participant names and any other identifying information will not be released
 from the clinic and it will not be used in any published reports about this study. There
 is a need to share protected health information with the study staff at the clinic and
 because of this, absolute confidentiality cannot be guaranteed.

 Women who are pregnant or nursing a child may not take part in this study. Women who become
 pregnant during the duration of the study will be withdrawn.

 There is no guarantee that participants will receive any direct benefit from being in this
 study. There is a possibility that ABUS may be better in detecting early breast cancer than
 mammogram or physical examination alone. Early detection of breast cancer may lead to more
 effective treatments in the future.

 This study presents subjects with the opportunity to receive ABUS at no additional cost to
 them or their insurance when they would otherwise not be entitled to this benefit. Currently,
 ABUS is FDA approved as an adjunct to mammography and is most commonly used in women who have
 known breast abnormalities; those women are not eligible for the study. Women who choose not
 to participate in the study, and women who are not eligible for the study, will not receive a
 screening ABUS exam at no cost to them or their insurance.

 All study participants will be helping us evaluate a specific use for the FDA approved ABUS
 system: screening women with dense breasts. If ABUS is proven to improve early breast cancer
 detection rates in women with dense breast tissue, the standard of care for breast screening
 may change so that all women with dense breast tissue may receive ABUS as part of standard
 care in addition to screening mammography, and will reduce the number of women who die from
 breast cancer every year. If no improvement in breast cancer is proven, the standard of care
 will not change and future patients and doctors will benefit from the knowledge that routine
 screening mammography is the most effective program for early breast cancer detection.

 Participants will not be reimbursed for their time in participating in this study and they
 will not receive any payment for participating in the study.

 The sponsor, U-Systems, Inc., will pay for this research study and provide funding to the
 study doctor for study related procedures and management of the study records.
