Power of Liquid Biopsy Tracking in Immunotherapy Treated Stage IV Melanoma

Sponsor: Royal Marsden NHS Foundation Trust

Summary

The advent of immune ICI has remarkably improved survival in advanced melanoma patients in the last decade. Long term responders following 2 years of treatment with immunotherapy go on to surveillance with frequent radiological imaging every 3-6 months up to 5-10 years. This not only exposes patients with a relatively low risk of recurrence to significant amounts of ionising radiation, but also increases the burden and cost on already stretched radiology departments. Therefore, this study aims to assess the feasibility and patient experience of using ctDNA with minimally invasive liquid biopsy assays as a biomarker for detecting disease relapse or progression at the point of radiological progression. Data from this pilot study will help to design a future validation study for establishing optimal liquid biopsy for surveillance in advanced melanoma patients.
