Metabolic Phenotyping and Systems Biology in Surgery
In Brief
An observational study for Colon Cancer and 4 related conditions. Completed, enrolled 50 participants across 1 site.
Detailed Summary
This work will use a new approach to measure how surgery effects human biochemistry and metabolism. It will create a metabolic signature or 'phenotype' for surgical injury that will help clinicians choose the right surgical treatments for an individual. This is because metabolism is based on an individual's genes, disease burden and environmental influences such as gut microbiota. This study will use a scientific method based on computational analysis of spectra taken from techniques known as Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) spectroscopy. This science is called 'metabonomics' and it has many advantages. Firstly, it provides a measure of thousands of metabolites at a single moment in time that are unique to the individual and it therefore gives a 'systems' overview of a persons metabolism. Secondly it is able to process many hundreds of samples quickly. The investigators are aiming to integrate the investigators metabolic data with genetic information about patients or bacteria wherever possible. This will be the first time that a 'systems biology' approach has been used in surgery, with potentially significant gains to me made in pre operative risk stratification and optimisation. By performing this analysis at all stages of the surgical journey (preoperatively, during the operation and after the surgery) it will ensure the right treatments are given to the right patient at the right time. By creating longitudinal models of the biochemical responses to surgery, predict at a much earlier stage those patients at risk of developing complications. This will improve outcome after surgery. This work will use a metabonomic approach to create new tools for surgeons to use during operations based on tissue biology. For example the investigators will be able to measure the metabolic content of tumours in real time by measuring the biological content of diathermy smoke. This has the potential to change intra-operative decision making and further improve outcome.
