Breast Cancer Clinical Trial
Extent of Breast Cancer and the Role of Pre-Operative Sonography and MRI
Summary
This clinical trial studies mammography and targeted ultrasound with or without whole-breast ultrasound or contrast-enhanced magnetic resonance imaging (MRI) in finding out the extent of disease before surgery in patients with newly diagnosed breast cancer. New diagnostic imaging procedures, such as whole-breast ultrasound or contrast-enhanced MRI, may help find out how far breast cancer has spread. It is not yet known whether mammography and targeted ultrasound are more effective with or without whole-breast ultrasound or contrast-enhanced MRI in finding out how far breast cancer has spread.
Full Description
PRIMARY OBJECTIVES:
I. To determine how surgical treatment is influenced by the three imaging arms.
II. To compare three imaging arms in terms of accurately measuring the size of the index lesion and the number and location of tumor foci (using surgical pathology as gold standard).
SECONDARY OBJECTIVES:
I. In women with dense breasts: To retrospectively compare the accuracy of three imaging arms in measuring the size of the index lesion and the number and location of tumor foci (using surgical pathology as the gold standard).
II. To report the incidence of synchronous contralateral breast cancers detected by the three imaging arms.
OUTLINE: Patients are assigned to 1 of 3 treatment groups.
GROUP 1: Patients undergo standard of care diagnostic imaging comprising bilateral mammography and targeted breast ultrasound.
GROUP 2: Patients undergo standard of care diagnostic imaging as in Group 1. Patients also undergo bilateral whole-breast ultrasound.
GROUP 3: Patients undergo standard of care diagnostic imaging as in Group 1. Patients also undergo bilateral breast contrast-enhanced MRI.
All patients undergo standard of care breast conserving surgery, or mastectomy if the tests indicate a change in the surgical plan.
Eligibility Criteria
Inclusion Criteria:
Competent to provide informed consent
Pathologically proven invasive breast cancer or ductal carcinoma in situ (DCIS) originally identified clinically or mammographically and diagnosed by percutaneous core biopsy
Eligible for breast conserving surgery followed by radiation therapy
Exclusion Criteria:
Women with surgical excisional biopsy that diagnosed the breast cancer
Women with clinical or mammographic findings where breast conserving surgery is not an option
Women that clinically or mammographically have breast cancers that are fixed to skin
Women receiving neoadjuvant chemotherapy prior to surgery
Women having contraindications to contrast-enhanced (CE)-MRI examination (e.g., claustrophobia and allergy to gadolinium)
