Study Description

Brief Summary: 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.

Detailed Description: 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).
