Potential Use of Indocyanine Green as a Fluorescent Agent for Definition of Surgical Margins in Cancer

Phase 1
Completed
Conditions
Malignant Neoplasm
Interventions
Drug: Indocyanine green (ICG)
Registration Number
NCT01884584
Lead Sponsor
Emory University
Brief Summary

The surgeon may remove a very small amount of additional tissue compared to what would be removed if you were not enrolled in the study. This tissue may prove to contain tumor or it may contain normal tissue. The surgical cavity will be examined by a special laser pen after the tumor is removed, and if areas of fluorescence are seen, that may indicate tumor cells where the ICG dye collected are still remaining and the surgeon would then remove those. After the tumor and the tissue around it are removed and sent to the laboratory, the tissue may be examined using that same laser pen to see where the cancer cells are and compare that to what the laboratory sees when it looks at the tumor and tissue with a microscope. It is hoped that what the dye shows and what is seen with the microscope will be alike.

Detailed Description

PRIMARY OBJECTIVES:

I. To validate the use of intraoperative indocyanine green (ICG) for better definition of tumor margins therefore, minimizing the necessity of a second surgical procedure to obtain negative margins.

OUTLINE:

Patients receive indocyanine green solution intravenously (IV) between 2-8 hours before surgery. Fluorescence measurements are taken from all specimens removed during surgery.

After completion of study, patients are followed up at 48 hours.

Primary Outcome Measures
NameTimeMethod
The contrast ratio (CR, defined as the integrated fluorescence intensity measured in a known tumor area divided by the integrated fluorescence intensity of a known "not tumor" area)1-2 weeks

Examine the resected tissue to determine whether ICG is sensitive to tumor detection (i.e., whether ICG accumulates in tumor) and whether ICG is specific for tumor (i.e., whether ICG accumulates in normal tissue).
