Additional Information
Here you find, in chronological order, further information on the topic of proton therapy at the CPT of the PSI.
A more efficient degrader for proton therapy
At PSI’s Center for Proton Therapy (CPT), protons are used to treat cancerous tumours in a highly targeted way that spares healthy tissue as much as possible. This is the result of the characteristic way in which charged particles interact with matter, so that a beam of protons deposits most of its energy at a certain depth in a material depending on the energy and the composition of the material. The dedicated medical cyclotron COMET accelerates protons to an energy of 250 MeV, which then have to be "slowed down" so that the energy matches the depth of the tumour to be treated.
A Swiss premiere Proton radiotherapy to treat oesophageal cancer
On 15 August 2023 a patient suffering from oesophageal cancer was treated with proton beam therapy at PSI – for the very first time in Switzerland.
Proton therapy: a success story that started 25 years ago
25 November 1996: a world first for PSI’s Center for Proton Therapy in treating a cancer patient using the spot-scanning technique.
A first for Switzerland: proton therapy to treat lung cancer
On 9 November 2021 a lung cancer patient was given proton therapy at the Paul Scherrer Institute PSI for the first time in Switzerland.
"Ultimately, we aim to understand how diseases start in single cells"
Imaging and sequencing techniques combined with machine learning offer researchers countless opportunities to look inside cells with greater precision than ever before. G.V. Shivashankar, lab head at PSI, describes how such information can be used to find answers to pressing questions.
New technique for ultrafast tumour therapy
For the first time, researchers at the Centre for Proton Therapy at PSI have tested ultrafast, high-dose irradiation with protons. The new, experimental FLASH technique could revolutionise radiation therapy for cancer.
Open fire on tumours
At the treatment stations of the Centre for Proton Therapy at PSI, tumours can be precisely irradiated from any direction. An interactive graphic explains how the protons get from the source to the body in order to trigger the elimination of tumour tissue.
"It's important to keep doing research"
Proton therapy is time-consuming and more costly than conventional radiation therapy, but its accuracy in targeting tumours is unsurpassed. An interview with Damien Weber, head of the Centre for Proton Therapy at PSI.
Cancer cells under attack
At PSI, cancer patients receive a therapy that is unique in Switzerland. Bombardment with protons wipes out cancer cells – and does so more precisely than with any other form of irradiation.
Children are her passion
At PSI, Beate Timmermann built up a programme providing proton therapy for children with cancer at the same time she was raising her own son. Today she is head of the Clinic for Particle Therapy at the West German Proton Therapy Centre in Essen (WPE) and is considered one of the most accomplished experts in this field.
