Fusing physics with medicine to fight cancer

May 2 2005

Everyone’s lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.

This was the key message to come from an event (28th April) which brought together 130 leading healthcare professionals and physicists. Speaking at The Future of Medical Imaging and Radiotherapy at the Institute of Physics in London, keynote speaker, Professor Alan Horwich, Director of Clinical Research and Development at the Institute of Cancer Research, Royal Marsden Hospital stated,

"I don’t think there is any discipline that has gained so much from technology developed for applied physics as cancer diagnosis and therapy. There is considerable potential for improving cancer cure rates over the next 10-15 years by the application of emerging imaging technologies to radiotherapy.

The event, organised by the Particle Physics and Astronomy Research Council (PPARC), showcased a number of technologies originally developed for particle physics experiments that have been successfully applied to the medical industry - particularly in relation to the diagnosis and treatment of cancer. These technologies include Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI), Computed X-Ray Tomography (CT) molecular imaging.

Nathan Hill, PPARC’s Industry Coordinator and UK Technology Transfer Coordinator for CERN said, Technology transfer from particle physics to the healthcare industry has already happened. By holding events such as this we are trying to stimulate the development of the next generation of technologies that will lead to earlier diagnosis and more effective therapy.

He adds, Several of the industrial/academic collaborations to date have resulted in the development of successful spin out companies - bringing the physics technology to the medical market place. There is no better demonstration of how particle physics impacts on the lives of ordinary people than when the technologies employed result in improved diagnostic treatments for patients.

PPARC has been instrumental in setting up collaborations between its scientists and industrialists. Fourteen of its collaborative projects are in the field of healthcare. Examples of those featured at today’s event include:-

• a camera for medical imaging developed by the Rutherford Appleton Laboratory, Institute of Cancer Research and the Royal Marsden Hospital. The novel positron camera (PETTRA) is based on a gas filled ionisation chamber as developed for particle physics at CERN by nobel prize winner, George Charpak.

• a sensitive camera for monitoring cancer treatment based on technology from X-Ray astronomy developed by a collaboration between scientists at the university of Leicester and the Queen’s Medical Centre, University of Birmingham.

• the development of a compact imager for the detection of breast cancer by a team from scientists from different departments at University College, London. This project is based on technologies used in detecting high energy particles (e.g. Opal experiment at the LEP detector, CERN and the Minos experiment).

One example of a successful healthcare spinout company resulting from an industrial/academic collaboration is Mirada Solutions. The origins of the company lie in a spin out from the University of Oxford, which was initially funded by Oxford University and private angel investment from Lady and Sir Martin Wood, with subsequent VC investment.

Mirada Solutions produces clinical software for Positron Emission Tomography (PET) and molecular imaging for clinical and pharmaceutical R&D use. Mirada’s products focus on the early detection of neurological diseases and cancer, and in the development of new applications in pharmaceutical research, disease monitoring and therapy. Mirada is now part of the CTI Molecular Imaging group of companies (NASDAQ: CTMI) following acquisition in late 2003.

Dr Chris Behrenbruch, President of CTI Mirada Solutions said, the UK is becoming an increasingly rich environment for academic-industry collaboration and the creation of new, highly innovative healthcare businesses. Creating a climate for innovation not only requires access to the best minds and clinical practitioners, but a mutual understanding of the intellectual property, regulatory and commercialisation issues associated with commercialising university and institutional R&D.

He adds, Medicine is no longer just about doctors. It is about partnerships between engineers, physicists, biologists and chemists - all with a strong desire to collaborate.
