Sentinel Lymph Node Detection in Patients With Stage Ib-III Melanoma Using MSOT and ICG

Study Purpose

In this study the investigators try to identify the sentinel lymph node in patients with stage Ib-III melanoma in a non-invasive manner without the use of a radioactive tracer by using the new MSOT technology.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

Exclusion Criteria:
- Apparent hyperthyroidism or autonomous thyroid adenoma of the thyroid gland.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05467137
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 4

Additional Details

Over the past few decades, melanoma has been one of the fastest-growing cancers and the incidence rate of melanoma is still increasing. Standard treatment for melanoma is wide (re)excision. Sentinel lymph node (SLN) biopsy (SLNB) is recommended for patients with melanoma of AJCC stage pT1b or higher according to Dutch guidelines. SLNB provides essential staging information that impacts on the clinical management of patients with melanoma, and the presence of SLN metastasis indicates a significantly worse prognosis. However, the overall complication rate of SLNB is high. Currently, lymphoscintigraphy using 99mTc-nanocolloid Technetium-99m-nanocolloïd (Tc99m) is the gold standard to identify the sentinel lymph node. However, there are various disadvantages of using 99mTc-nanocolloidTc99m: the involvement of radioisotopes represents a radioactive burden for patients and caregivers, the lymphoscintigraphic imaging has poor spatial resolution, and the involvement of radioisotopes is expensive and creates logistic challenges. Therefore, in this study the goal is to identify the sentinel lymph node in a non-invasive manner without the use of a radioactive tracer. The investigators try to reach this goal by using the fluorophore dye IndoCyanine Green (ICG) and multispectral optoacoustic imaging (MSOT). MSOT is a new, but increasingly used, imaging modality that has emerged the field of optical imaging. MSOT is based on a highly powerful pulsed laser in different wavelengths. Photo absorbing molecules absorb laser light in a specific wavelength, undergo thermal expansion and create soundwaves which can be detected by special transducers. The MSOT combines conventional ultrasonography with optoacoustic imaging which gives both anatomical and biological information and is currently available in the University Medical Centre Groningen (UMCG).
