Breast Carcinoma
Conditions
Brief summary
This clinical trial studies the use of contrast-enhanced ultrasound (CEUS) in estimating tissue pressure in patients with breast cancer. Diagnostic procedures, such as CEUS, may help estimate tissue pressure noninvasively.
Detailed description
PRIMARY OBJECTIVE: I. To determine if the 3-dimensional (3D) subharmonic aided pressure estimation (SHAPE) results can be used to estimate interstitial fluid pressures (IFPs) in breast tumor and its surrounding tissue. SECONDARY OBJECTIVE: I. To determine if the malignancy of breast tumor can be predicted by the 3D SHAPE results. OUTLINE: Patients undergo ultrasound without contrast. Patients then receive perflutren lipid microspheres (Definity) intravenously (IV) over 15 minutes and undergo CEUS.

Eligibility
Inclusion criteria
* Provide signed and dated informed consent form * Be conscious, willing and able to comply with all study procedures and be available for the duration of the study * At least 21 years old * Be scheduled for a breast biopsy (Breast Imaging Reporting and Data System \[BIRAD\] 4, 4A, 4B, 4C or 5) * Patient with an at least 1 cm mass located at \< 3 cm depth, approachable by 2.5 inch needle * Be medically stable as determined by the investigator * If a female of child-bearing potential, must have a negative urine pregnancy test within 24 hours prior to administration of Definity
Exclusion criteria
* Females who are pregnant or nursing * Patients who are medically unstable, patients who are seriously or terminally ill, and patients whose clinical course is unpredictable. For example: * Patients on life support or in a critical care unit * Patients with unstable occlusive disease (e.g., crescendo angina) * Patients with clinically unstable cardiac arrhythmias, such as recurrent ventricular tachycardia * Patients with uncontrolled congestive heart failure (New York Heart Association \[NYHA\] class IV) * Patients with recent cerebral hemorrhage * Patients who have undergone surgery within 24 hours prior to the study sonographic examination * Patients with known hypersensitivity or allergy to any component of Definity * Patients with unstable cardiopulmonary conditions or respiratory distress syndrome * Patients with uncontrollable emphysema, pulmonary vasculitis, pulmonary hypertension or a history of pulmonary emboli
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation Between Subharmonic Aided Pressure Estimation (SHAPE) Results and Direct Measurements of Interstitial Fluid Pressure (IFP) | during the procedure (approximately 90 minutes) | Pearson's correlation coefficients will be computed between SHAPE results and direct IFP measurements by Stryker compartment pressure monitoring system. A Pearson's correlation coefficient above 0.5 will be considered a successful outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| SHAPE Gradient Values by Malignancy Status | during the procedure (approximately 90 minutes) | The secondary objective of the study is to determine if the malignancy of breast tumor can be predicted by the 3D SHAPE results. We will use the results from the biopsy as the reference standard. The significance level of Generalized linear mixed logistic or GEE logistic modeling as well as the Mann-Whitney or Student's t-test will be 0.05. |
| Invasive IFP by Malignancy Status | during the procedure (approximately 90 minutes) | The secondary objective of the study is to determine if the malignancy of breast tumor can be predicted by invasive Interstitial Fluid Pressure (IFP). We will use the results from the biopsy as the reference standard. The significance level of Generalized linear mixed logistic or GEE logistic modeling as well as the Mann-Whitney or Student's t-test will be 0.05. |
