What You Need to Know Before You Apply

What is the purpose of this trial?

This trial uses a special dye called ICG to help surgeons see and remove bone or soft tissue tumors more effectively. The dye lights up the tumor under a special camera, making it easier to ensure all of it is removed. This approach aims to improve surgical outcomes for patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is indocyanine green (ICG) dye safe for use in humans?

Indocyanine green (ICG) dye is generally considered safe for use in humans, but rare adverse effects like severe hemodynamic instability (serious blood flow issues) and anaphylactoid reactions (severe allergic reactions) have been reported. ^{1 2 3 4 5}

How is the drug Indocyanine green (ICG) unique for cancer surgery?

Indocyanine green (ICG) is unique for cancer surgery because it is a dye that helps surgeons see tumors and important structures during surgery using fluorescence (a special light that makes the dye glow). This makes it easier to locate tumors and ensure proper blood flow to tissues, which is different from traditional methods that don't use this glowing effect. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Indocyanine Green (ICG) for cancer surgery?

Research shows that Indocyanine Green (ICG) is effective in helping surgeons see and remove tumors more safely by highlighting important structures and improving surgical outcomes. It is used in various surgeries, including colorectal and breast cancer, to identify lymph nodes and assess blood flow, making surgeries more precise and reducing complications. ^{4 11 12 13 14}
