Summary

The aim of this study is to assess feasibility of a new imaging technology in the management of breast cancer - Tumor Microenvironment of Metastasis - Magnetic Resonance imaging (TMEM-MRI).

Detailed description

The primary objective of this study is to develop a magnetic resonance imaging (MRI) based method for assessing TMEM-mediated permeability associated with cancer cell dissemination in breast cancer patients. TMEM-MRI has the ability to detect tumor areas with more leakiness (perfusion), where cancer cells enter blood vessels to travel to other sites. This novel TMEM-MRI has potential to be used in clinical practice to identify tumors with high leakiness that might have higher chances to recur after breast cancer treatment. In addition, TMEM-MRI can potentially be used to assess response to preoperative treatments (chemotherapy, hormonal therapy) over time. In a prior study, it was found that patients with high TMEM doorway score, compared to patients with mid/low TMEM doorway score, in their residual disease after neoadjuvant therapy, had worse distant relapse-free survival (p = 0.008). These results demonstrated that TMEM doorway density after neoadjuvant therapy is a prognostic biomarker of breast cancer outcomes. In the initial development of the proposed TMEM MRI in humans, the tumor microenvironment is naïve to treatment. However, neoadjuvant therapy may affect the tumor microenvironment which could affect vascular anatomy - a key component of the TMEM MRI algorithm. Therefore, the study team aims to assess the correlation between TMEM doorway density and TMEM MRI activity after neoadjuvant therapy (Pilot Cohort C).

• Breast Cancer

Interventions

Type	Name	Description
DEVICE	TMEM-MRI	TMEM MRI INFORMATION: Unilateral breast MRI will be obtained on a 3.0T whole body MRI scanner with a dedicated breast radiofrequency coil. The patient will be scanned in the prone position with an in-dwelling IV catheter for a single dose contrast agent injection.
PROCEDURE	FNA	FNA: The patients who are recruited prior to biopsy (Cohort A) will have had TMEM-MRI performed prior to biopsy. They will then present to radiology for ultrasound-guided core biopsy of the breast mass. FNA will be performed during this procedure. The FNA will be performed after local anesthetic is administered but prior to insertion of the core biopsy needle. FNA will be performed by the radiologist under direct sonographic visualization of the mass. Five passes will be obtained with a 25-gauge needle. The FNA material will be expelled into 1.5 ml Eppendorf tube containing phosphate buffered saline with Ethylenediaminetetraacetic acid (EDTA).
