Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with benign or malignant bone or soft tissue masses scheduled for surgery at Massachusetts General Hospital.

Probably not a fit

Patients who are pregnant, nursing, or have known allergies to IV contrast or iodine 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 study investigates the effectiveness of indocyanine green (ICG) dye in identifying tumor margins during the surgical resection of benign and malignant bone or soft tissue masses. Patients will receive ICG via injection before surgery, and its fluorescence will be monitored during the procedure to ensure complete tumor removal. The study aims to determine if ICG-guided resection leads to better oncologic outcomes, including local recurrence and overall survival rates.

Why it matters

Potential benefit: If successful, this approach could lead to more effective tumor resections and improved patient outcomes.

How similar studies have gone: Other studies using ICG for tumor margin identification have shown promising results, indicating potential for success in this approach.
