Study Description

Brief Summary: A prospective feasibility trial initially including 10 patients to investigate if Neurofilament light protein can be detected in peripheral blood in patients undergoing Isolated Limb Perfusion with chemotherapeutic agents. This biomarker could act as predictive biomarker for neurotoxicity after isolated limb perfusion.

Detailed Description: In isolated limb perfusion (ILP) neurotoxicity is a known side effect, this is in spite of the fact that a relatively mild hyperthermic temperature is used which should be well tolerated by the nerves and other normal tissues in the limbs. It seems probable that the neurotoxicity observed after ILP results from both a thermal enhancement of drug toxicity combined with a local effect of a high tourniquet pressure that is used to isolate the blood flow. Prevention of regional and systemic toxicity is essential for improving the outcome after the procedure. It is known that both higher doses of melphalan, higher temperatures and longer perfusion time correlates to a higher toxicity. The Wieberdink method is a grading system for the reaction of the normal tissues after ILP and the grading is used as a routine in ILP today. Neurofilament light protein (NfL) is released into the cerebrospinal fluid (CSF) during axonal damage and has been shown to be elevated in different forms of dementia. An NfL assay sensitive enough to measure NfL in blood was recently developed. Its concentration reflects axonal injury in both central and peripheral nervous system disorders.The primary aim of this study is to investigate the possibility to measure neurofilament as a biomarker for peripheral nerve toxicity after isolated limb perfusion.
