Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are on anticoagulant medication (blood thinners), you must be willing to stop using them before the procedure.

What data supports the effectiveness of the treatment Molecular Breast Imaging (MBI) for breast cancer?

Molecular Breast Imaging (MBI) is effective in detecting additional hidden breast cancers in 9% of women with newly diagnosed breast cancer and has a high sensitivity for detecting high-risk lesions, identifying 98% of invasive breast cancer and 91% of ductal carcinoma in situ. It is also useful for women with dense breasts, detecting hidden cancer in up to 16.5 per 1000 women, and influences surgical management in nearly a quarter of women with newly diagnosed breast cancer.12345

Is Molecular Breast Imaging (MBI) safe for humans?

Molecular Breast Imaging (MBI) is considered safe for humans, with minimal radiation risk similar to that of mammography. It is well tolerated and has been integrated into clinical practice for over a decade.12356

How is the treatment Molecular Breast Imaging (MBI) different from other breast cancer treatments?

Molecular Breast Imaging (MBI) is unique because it uses a special type of camera to detect breast cancer based on how the tissue functions, rather than just its structure, which is how traditional mammograms and ultrasounds work. This allows MBI to find cancers that might be hidden in dense breast tissue and can guide biopsies of suspicious areas that other methods might miss.12378

What is the purpose of this trial?

This clinical trial tests how well molecular breast imaging (MBI) works to guide the collection of a breast biopsy in patients with a breast abnormality. Currently, a biopsy is often guided by either ultrasound or mammography in order to ensure that a sample of the correct part of the breast is taken. Sometimes a lesion or part of the lesion cannot be seen on ultrasound or mammography, and, therefore, a biopsy guided with ultrasound or mammography may not be always be accurate. Studies have shown that high resolution MBI may have potential to improve the detection of some breast tumors. This trial uses a new high-resolution MBI system that may help perform a biopsy using MBI.

Eligibility Criteria

This trial is for women aged 18 or older who have had a benign breast abnormality detected by MBI in the past 3 years. They must not be pregnant, breastfeeding within the last 2 months, or have had recent breast surgery. Participants need a negative pregnancy test before biopsy if they can become pregnant and must consent to join.

Inclusion Criteria

You had a breast imaging test in the last 3 years that found something in your breast, but it turned out not to be harmful after more tests or check-ups.
I need a biopsy for a breast abnormality found on an imaging test.
You had a breast imaging test in the past 3 years that found something in your breast, but further tests showed it was not cancer.

Exclusion Criteria

I had breast surgery within the last year.
I am under 18 years old.
I have a breast implant in the breast with the cancer.

Treatment Details

Interventions

  • Molecular Breast Imaging
Trial Overview The study evaluates high-resolution molecular breast imaging (MBI) as a guide for biopsy in patients with breast abnormalities. It aims to see if MBI is more accurate than ultrasound or mammography when these methods don't show clear images of lesions.

Findings from Research

Molecular breast imaging (MBI) detects additional hidden breast cancers in 9% of women with newly diagnosed breast cancer and has a high sensitivity of 98% for invasive cancers and 91% for ductal carcinoma in situ.
MBI is increasingly used for monitoring treatment response in women undergoing chemotherapy and can influence surgical decisions in nearly 25% of newly diagnosed breast cancer patients, highlighting its importance in clinical practice.
Molecular Breast Imaging: A Comprehensive Review.Huppe, AI., Mehta, AK., Brem, RF.[2018]
Molecular breast imaging (MBI) is an effective nuclear medicine technique for detecting breast lesions that may be cancerous, with advancements allowing for tissue sampling from these lesions using specialized camera systems.
The article provides guidance on integrating MBI and MBI-guided biopsy into breast imaging workflows, emphasizing the importance of selecting appropriate biopsy equipment and ensuring radiation safety during the process.
Molecular Breast Imaging-guided Percutaneous Biopsy of Breast Lesions: A New Frontier on Breast Intervention.Adrada, BE., Moseley, T., Kappadath, SC., et al.[2021]
Molecular breast imaging (MBI) is an effective and cost-efficient method for detecting breast cancers that may be hidden in dense breast tissue, which is often a limitation of traditional mammography.
Recent studies suggest that the uptake levels of the imaging agent in benign dense tissue could provide valuable information regarding breast cancer risk, highlighting the potential for MBI to not only detect cancer but also assess risk factors.
