Fluorescent dye used during lumpectomy to highlight tumor edges

Fluorescence-guided resection of breast tumors using a topically-applied molecular probe

NIH-funded research Case Western Reserve University · NIH-11404102

This project uses a special fluorescent probe applied to the breast during lumpectomy to help surgeons see cancer at the tissue edge more clearly for women having breast-conserving surgery.

What this research studies

During breast-conserving surgery a clinician will apply a topical molecular probe to the removed tissue and/or surgical cavity and use a fluorescence camera to visualize any remaining cancer at the margins. The team combines imaging with pathology to determine whether the probe lights up areas that standard inspection or routine pathology might miss. The goal is to guide surgeons in the operating room so fewer patients need a second operation for positive margins. Work likely includes laboratory testing of the probe and clinical testing at the surgical site to compare fluorescence with final pathology.

Who could benefit from this research

Good fit: Ideal candidates are people with early-stage breast cancer who are scheduled for breast-conserving surgery (lumpectomy).

Not a fit: People who require mastectomy, have widespread metastatic disease, or cannot undergo surgery would not be candidates and are unlikely to benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could reduce re-operations, improve cosmetic results, and lower the chance of local recurrence after lumpectomy.

How similar studies have performed: Fluorescence-guided surgery has shown benefit in other cancers and surgical settings, but topical fluorescent probes for lumpectomy margins remain relatively new with limited clinical data.
