Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with histologically confirmed invasive lobular carcinoma.

Probably not a fit

Patients with early-stage breast cancer (Stage I-III) or those without lobular histology on tumor biopsy may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational registry aims to collect data from patients with invasive lobular carcinoma (ILC) of the breast to develop a specific response assessment tool. The study will evaluate the feasibility of a histologic-based registry and analyze treatment patterns, natural history, and overall survival using real-world data. Participants will be recruited during clinic visits and will provide blood samples at various evaluation points, with follow-up until loss to follow-up, death, or withdrawal from the registry.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment strategies for patients with metastatic lobular breast cancer.

How similar studies have gone: While this approach is observational and builds on existing knowledge, similar studies have shown promise in understanding metastatic breast cancer dynamics.
