About the GPTC


The University Medical Centre Groningen (UMCG) is working on the construction of a proton facility, the UMC Groningen Proton Therapy Centre (GPTC for short).

On 2 December 2013, the Dutch minister for Health, Welfare, and Sports granted the UMCG the authorisation to construct the GPTC.

The first patients are expected to be able to receive treatment at the GPTC as of the end of 2017.

The GPTC will be constructed on UMCG grounds. This will allow patient care for this facility to be fully integrated within the multidisciplinary care programmes of the UMC Groningen Comprehensive Cancer Centre.


The GPTC will consist of the following components:

  • Cyclotron: the part of the facility where protons will be generated.
  • Transportbundle: the part that connects the cyclotron to the treatment rooms.
  • Two treatment rooms: the part where patients undergo the radiation treatment sessions.

The treatment rooms are equipped with gantries that will allow protons to be directed at a tumour from all directions.

It will be possible to treat 600 patients at the GPTC every year.
