From Physics to Medicine: Hadron Therapy CERN – Bulgarian Industry 28 - 29 November 2012 Manjit Dosanjh, KT-LS
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
CERN Technologies and innovation accelerators, detectors and IT to fight cancer Detecting particles Accelerating particle beams Large-scale computing (Grid) CANCER Manjit Dosanjh First Bern Cyclotron Symposium - June 5-6, 2011 3
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 Life.Sciences@cern.ch KT-LS 26 May 2011 4
Cancer incidence increases with age
Contribution from CERN is timely 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
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. ULICE Kick-off in 2009 ENVISION approval in 2009 Enlight meeting leading to subm. Of ENTERVISION PARTNER: 21 researchers recruited last year.
4 Pillars: 3 are the key technologies 4th pillar: catalysing and facilitating collaboration 4 Pillars: 3 are the key technologies Particle Therapy Tumour Target Accelerating particle beams Detecting particles Medical imaging Large scale computing (Grid) Grid computing for medical data management and analysis

Positron Emission Tomography Idea of PET Photon detection used for calorimetry PET today CMS
PET (Positron Emission Tomography) Detects pairs of photons emitted by an injected positron- emitting radionuclide Images tracer concentration within the body Reflects physiological activity Reconstructed by software LHC detector systems used in PET Systems 12
PET/CT (David Townsend)
In-beam-PET for Quality Assurance: real time MC simulated measured On-line determination of the dose delivered Modelling of beta+ emitters: Cross section Fragmentation cross section Prompt photon imaging Advance Monte Carlo codes In-beam-PET GSI- Darmstadt
Computing Technologies GRID – data storage, distributed, safe and secure computing MammoGrid: European-wide database of mammograms and support collaboration Health-e-Child: combining various types (clinical, imaging…) of data and share in distributed, clinical arena. HISP: Hadrontherapy Information Sharing Platform
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) 16

Two opposite photon beams 110 100
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 19
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 Depth in the body (mm) Conventional: X-Rays Ion Radiation 20
