Virtual Tumours bring Insights to Drug Delivery
Oct 20 2018 Read 341 Times
University College London (UCL) scientists have designed a virtual modelling technique to create highly detailed 3D models of individual cancerous tumours which can be used for simulation of drug delivery and prediction of their effectiveness.
In the study*, researchers used the technique, named REANIMATE (REAlistic Numerical Image-based Modelling of biologicAl Tissue substrates) to run detailed computational experiments on high-resolution images of surgically-resected tumours, which allowed them to study the transport of blood, biological fluids and drugs, also their complex interactions with tissue.
Joint lead academic Dr Simon Walker-Samuel (UCL Centre for Advanced Biomedical Imaging) said: “These advances are a truly interdisciplinary effort and would not be possible without the combined input of physicists, mathematicians, cancer biologists, clinicians, imaging specialists and engineers.
“The new framework has a vast potential impact in helping to develop new cancer drugs and potentially providing a cost-effective way to test their efficacy before going to human trials. It advances the move towards truly personalised medicine, with the potential aim that one day clinicians might be able to predetermine the most effective therapeutic plan for each patient’s unique tumour makeup.”
Joint lead academic Dr Rebecca Shipley (Director, UCL Institute of Healthcare Engineering) said: “REANIMATE uses optical imaging of surgically extracted tumour samples to generate virtual models of tumour structure at a microscopic scale. This is the basis for us to perform mathematical modelling, which also integrates quantitative MRI images taken before the tumour was extracted. This is a novel approach that provides an entirely new framework for therapy prediction in tumours and we are now developing ways of applying it to images taken from patient biopsies.”
The research was led by Dr Simon Walker-Samuel and Dr Rebecca Shipley, with UCL Division of Medicine, UCL Mechanical Engineering and UCL Institute for Healthcare Engineering, in close collaboration with colleagues and with the support of the Rosetrees Trust and the Wellcome Trust.
