Brief Summary:
This is a Danish national multicenter prospective cohort study to evaluate if fluorescence-guided surgery (FGS) using indocyanine green (ICG) can reduce the rate of positive margins following sarcoma resection.
Detailed Description:
This is a Danish national multicenter prospective cohort study to evaluate if fluorescence-guided surgery (FGS) using indocyanine green (ICG) can reduce the rate of positive margins following sarcoma resection.
Biopsy verified intermediate-to-high grade sarcoma of the extremity or trunk wall are eligible for inclusion. To be included there must be curative intent at time of surgery.
The primary endpoint will be re-resection within 30 days due to positive margins on the initial resection. Tumor characteristics and margin status from pathology reports will be recorded. Data on reoperations due to other factors, positive margins without planned reoperation, or death will also be collected. Participants will undergo surgery with ICG administered and guided using the SPY-PHI.
The prospective cohort will be compared to a historic cohort having received standard of care treatment. The historic cohort is included to act as a control group to compare with the new procedure. The data is derived from the Danish Sarcoma Database and permissions for this is in process. This data does not involve access to patient EMRs.
Patients will receive an intravenous bolus of 1 mg/kg fluorescent ICG dye 16-24 hours before surgery. During surgery, consecutive measurements will be recorded using the SPY-PHI. Surgical resection will be guided by the fluorescent signal. The wound bed will be inspected, areas with fluorescent signal will be excised and obtained separately for histopathology. Patients will receive the current post-operative standard of care for sarcoma patients.
Approximately 20 minutes of additional surgical time is expected.
