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
