About this study

This study investigates whether adding the optical imaging to magnetic resonance imaging can improve the diagnostic specificity of breast cancer.

Read the detailed description

This proposal will investigate the performance of a combined optical-MRI imaging system in diagnosis of breast cancer. A diffuse optical tomography (DOT) imaging system will be integrated with a 3.0 T MRI scanner. It is hypothesized that the additional information measured by the combined MRI/DOT system will improve the specificity of DCE-MRI (dynamic contrast enhanced MRI) in diagnosis of breast cancer.

High resolution anatomic MRI and DCE-MRI has evolved into a standard clinical tool for detection and diagnosis of breast lesions. Due to its high sensitivity MRI is fast becoming the most popular imaging modality for screening young women who are susceptible to early development of breast cancer. Pre-operative MRI has also become a common procedure for detecting multifocal or multicentric diseases to facilitate surgical planning. However, despite its high sensitivity, MRI also detects many benign lesions. The low specificity may lead to a great anxiety to patients, and many unnecessary biopsies or over-treatment. Other adjunct imaging modality to improve specificity is greatly needed. MR spectroscopy (MRS) and DOT are two techniques that have great potential to provide complementary information.

After the study is completed, we will be able to test the hypothesis that "additional information provided by MRS and optical imaging can be used in conjunction with morphological and kinetics parameters measured by DCE-MRI to improve diagnostic accuracy of breast cancer". Furthermore, we will be able to determine among these additionally collected information, which parameter(s) are the most essential in improving diagnostic accuracy.

Although the current breast imaging modalities have achieved a high success, further improvements for the subpopulation in whom conventional imaging does not work well are in great need. Our goal is to develop an imaging technology with optimized acquisition protocol to improve diagnosis of breast cancer, particularly for young women with dense breasts who need a breast MRI examination, so that they would not be subjected to false positive findings.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity, Specificity, and Overall Accuracy in Differentiating Between Benign and Malignant Lesions

    ROC curves obtained using the regression statistical approach and the artificial neural network will be used to assess the sensitivity, specificity, and overall accuracy in differentiating between benign and malignant lesions. The ROC curves using the optimized morphological and kinetic parameters measured by DCE-MRI will be obtained first, then compared to ROC curves analyzed using the optimized DCE-MRI parameters with the addition of (1) Choline measured by MRS, (2) hemoglobin concentration and oxygen saturation measured by steady state DOT, and (3) transport rates in ICG kinetics measured by dynamic DOT

    Measured: After we meet the enrollment target

Questions about this trial

What is this clinical trial studying?

A study testing Disease Group in people with Breast Cancer, run by University of California, Irvine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Apr 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity, Specificity, and Overall Accuracy in Differentiating Between Benign and Malignant Lesions (time frame: After we meet the enrollment target). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2020.
