Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective observational registry for patients with invasive lobular carcinoma (ILC) of the breast. After the first 1cohort is enrolled, the collected data will be utilized to develop an ILC specific response assessment tool.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Aims:

1. To evaluate the feasibility of developing a histologic based registry for participants living with metastatic lobular breast cancer.
2. To understand the natural history, treatment patterns, and overall survival in patients with metastatic ILC using modern, real-world data.

Secondary Aims:

1. To evaluate the correlation between imaging findings and disease progression.
2. To evaluate the correlation between ctDNA and disease progression.
3. To develop an ongoing platform for evaluating new imaging tools, tumor markers, and participant recruitment for clinical trials.

Outline:

Participants will be recruited to participate in the registry during a regularly scheduled clinic visit with their treating oncologist, and consented to participate at this time. At each evaluation time point, participants will have a blood draw performed. Participants will be followed until loss to follow up, death, or withdrawal from the registry.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Initial Cohort

Up to 12 participants at each evaluation timepoint (approximately every 3-6 months to follow standard of care visits) will have up to 40 mL of blood drawn and distributed into 8 cell-free DNA Streck tubes, for plasma isolation, cell free DNA extraction, and ctDNA analysis. Blood for ctDNA analysis will be collected within +/- 14 days of whole body imaging studies which will occur when patients are scheduled for standard of care whole body imaging.
