Added value for cancer patients

Human Health Medical Science Proton Therapy

At the Paul Scherrer Institute PSI, cancer patients receive a treatment that is unique in Switzerland: proton therapy. This state-of-the-art form of radiation therapy against cancer has major advantages, compared to conventional irradiation, in terms of effectiveness and side-effects. The PSI has its own Center for Proton Therapy dedicated to this special treatment. Its pioneering work has not only helped several thousand patients, but also has fundamentally changed proton therapy worldwide.

Getting a Handle on Safety

Medical Science Human Health Proton Therapy

Proton beams don’t just cure cancer. They can also damage healthy tissue. To make sure that this doesn’t happen, PSI’s Centre for Proton Therapy carries out over 350 safety tests a year. The results speak for themselves: several thousand patients have undergone proton irradiation treatment here in Villigen. There’s never been an accident.

Rays of hope for patients

Medical Science Human Health Proton Therapy

For over 30 years, patients with a particular form of ocular tumour have been treated at PSI by means of proton irradiation. The tiny particles hit their target with millimetre precision, without endangering other structures of the eye. The irradiation facility OPTIS, developed at the PSI Center for Proton Therapy of the PSI, is a success story, considering that for more than 90 percent of the patients treated to date, the eye could be saved.

Back to life

Medical Science Human Health Proton Therapy

Doctors had discovered, behind Gabi Meier’s right eye, a tumour that surrounded the optic nerve. Only at the PSI was there still one possibility to treat the tumour in such a way as to preserve neighbouring structures and the eye. A few months after the proton treatment was over, I realised that I could see more and more, she said in an interview. “Just dimly, it’s true, but I could see! That was sensational!”

20 years of high-precision combat against cancer

Medical Science Human Health Proton Therapy

On 25.11.1996, at the Paul Scherrer Institute PSI, the world’s first cancer patient was treated with a new irradiation method: the so-called spot-scanning technique for proton beams. What’s special about it: The beam has its effect only at the depth where the tumour is located; healthy tissue above and below it is preserved. The method, developed by PSI researchers, was a breakthrough at the time and quickly became a successful product.
