Knowledge and Technology Transfer • KT is an integral part of CERN’s mission • PP technologies relevant to key societal issues e.g. Health • CERN involved in the last 10-15 years in health applications few CERN resources attracted significant external funding (EC, MS…) raises impact and profile beyond the particle physics arena large number of collaborating institutes including medical institutes & hospitals
• Collaborators appreciate facilitation by CERN

Why Cancer ? •
Every year >3 millions new cases in Europe
•
About one third of us will have cancer
•
Number of patients needing treatment is increasing as people are living longer
•
Main cause of death between the ages of 45 and 65 in Europe
•
Second most common cause of death in Europe, Canada, USA after heart-disease Knowledge Transfer | Accelerating Innovation

Cancer incidence increases with age
Knowledge Transfer | Accelerating Innovation
Cancer is a large and growing challenge Need: Earlier diagnosis, better control, fewer side-effects
How? • new technologies •
• •
•
Imaging, dosimetry, accelerator & detector technology Better understanding – genetics, radiobiology… Advanced healthcare informatics …
international collaboration •
If progress is to be maintained
Although cancer is a common condition, each tumour is individual personalised approach Large patients data to understand the key drivers of the disease
Contribution from CERN is timely Knowledge Transfer | Accelerating Innovation
Catalysing collaboration in health field Challenges: • Bring together physicists, biologists, medical physicists, doctors • Cross-cultural at European and global level
Why is CERN well placed to do this? • It is widely acknowledged as a provider of technologies and as a catalyst for collaboration. • It is international, non-commercial, not a health facility.

Conventional Radiotherapy in 21st Century 3 "Cs" of Radiation Cure (~ 45% cancer cases are cured) Conservative (non-invasive, few side effects) Cheap (~ 5% of total cost of cancer on radiation) (J.P.Gérard) There is no substitute for RT in the near future The rate of patients treated with RT is increasing
Present Limitation of RT: ~30% of patients treatment fails locally (Acta Oncol, Suppl:6-7, 1996) Knowledge Transfer | Accelerating Innovation

How to decrease failure rate? • Physics technologies to improve treatment: higher dose • Imaging: accuracy, multimodality, real-time, organ motion • Data: storage, analysis and sharing (confidentiality, access) • Biology: fractionation, radio-resistance, radio-sensitization • Working together: multidisciplinary Raymond Miralbell, HUG

Hadrontherapy: all started in 1946 In 1946 Robert Wilson: – Protons can be used clinically – Accelerators are available – Maximum radiation dose can be placed into the tumour – Proton therapy provides sparing of normal tissues
Conventional: X-Rays
