Summary

The purpose of this research study is to use two different drugs to find where melanoma might spread and to remove these tissues. We believe that tumor cells from the melanoma first move through the lymphatic system (a system of clear fluid that moves around the body and carries white blood cells, much like the blood system) to a lymph node in an orderly way. If we can identify the first lymph nodes to receive a tumor cell, this can be removed and examined. We currently use one drug, called "technetium-99m sulfur colloid" which can detect about 90% of the first lymph nodes that the tumor cells would move to. Technetium-99m is a radioactive compound and can be detected through the skin by a special instrument that reads radioactivity. As part of this research, we would like to use a second drug called "fluorescein" (Fluorescite®) to see if it will identify the same lymph nodes or additional ones and examine these. This drug is fluorescent and can be detected even through the skin using a blue light. This drug is approved by the Federal Drug Administration (FDA) to for injection in the vein as a diagnostic aid and has been safely used in people for many years. In this study, we will be injecting it under the skin, which is a different use from how it is currently approved by the FDA. In the past another drug has been used, called "isosulfan blue" (Lymphazurin®), but availability of this drug is currently limited, and it has higher risks associated with it.

This study is being conducted by Dr. Robert Andtbacka, Dr. Dirk Noyes, Dr. James McGreevy and at University of Utah. This study is a Phase I/II and is done to find out if the drug can be used safely when given under the skin and if it will work for this purpose.

DRUG

Fluorescein

Fluorescein is an orange-red powdered compound, designated by the formula C20H12O5, which exhibits intense greenish-yellow fluorescence in alkaline solution. It has been used extensively in surgery and medicine for decades for diagnostic purposes. Topical fluorescein is routinely used in ophthalmology to assess corneal lesions. Intravenous fluorescein is used in vascular surgery to measure vascular perfusion and in skin and melanoma surgery to assess the viability of skin flaps.
