Near-infrared Fluorescence With Indocyanine Green for Identification of

Status Recruiting

Clinical Trial Summary

Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.

Clinical Trial Description

Incidence of thyroid cancer has doubled between 1980 and 2020, and it is now the fifth most common malignant tumor among women. The majority are papillary thyroid cancer (PTC), and TT is the procedure of choice. Since the micrometastasis rate of the central lymph nodes (CLNs) is about 30% to 90% in PTC, CLN dissection can improve the prognosis and reduce tumor recurrence as well as provide accurate information for the evaluation of tumor staging. However, TT procedure has some important complications such as vocal cord paralysis (VCP) and hypocalcemia (due to accicental parathyroidectomy or damage to the parathyroid gland-PG- vasculature). Use of intraoperative nerve monitoring (IONM) has reduced the rate of VCP. However, the incidence of postoperative hypocalcemia is still high (15-70%), and it is now the most common complication of TT. Intraoperative identification of SLNs and PGs can help surgeon to overcome these problems. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
