Clinical Trial Summary

This is a single centre, correlative, longitudinal, biomarker study that aims to describe the metabolic features of human melanoma using mass spectrometry.


Clinical Trial Description

This is a single-centre, correlative study designed to investigate metabolic phenotypes in a longitudinal cohort of patients with melanoma. This study will involve the collection of tissue at the time of surgical excision or biopsy. The key intervention, in a subset of patients, will be to perform peri-operative infusions of a stable isotope, [U13C]Glucose. Patients will be intravenously administered sterile, pyrogen-free 13C-glucose, delivered as an 8g bolus followed by infusion of 4g/hour for 2-3 hours. Blood samples will be obtained to monitor glucose and to analyse enrichment of labelled nutrients by gas-chromatography mass spectrometry (GC-MS). At the time of resection or biopsy, tumour samples will be divided and either immediately frozen in liquid nitrogen or processed to form patient-derived xenografts. Frozen tumour samples will be subsequently processed for: isotope enrichment by GC-MS; global metabolomics by liquid-chromatography mass spectrometry (LC-MS); and genomic analyses. Relevant clinical, histologic and genomic features will also be correlated with metabolic findings. ;
