Institutional membership is designed for hospitals, clinics or other institutions seeking to gain visibility in the ESTRO community and support their oncology teams in their professional development.

Institutes from all over the world have the possibility to purchase individual memberships (as of 5) for their radiotherapy and oncology team with gradual discounts (from 5% up to 25%) depending on the size of the group.

This year ESTRO is proposing a global and more cost-effective model that fosters interdisciplinarity and multidisciplinarity, ensuring professional growth for the entire team.


Joint membership is based on special agreements between ESTRO and other societies:

  • Non-European National Society
  • European Young National society (or by extension, the young members of a RO European National Society)
  • Oncology societies outside the RT field

Individual members of the partnering societies are eligible for full ESTRO membership at a reduced price.  The membership fee is either covered by the annual fee paid by the partnering Society or through online individual registration.

Joint membership fosters the collaboration between societies. It facilitates the international exchange of practices and enhances the importance of multidisciplinary care.

This membership type is based on agreements signed between ESTRO and a National Society representing RTTs (Radiation TherapisTs). It applies to all international societies.

Thanks to such agreements, individual members of RTT national societies can join ESTRO at a reduced fee, which is covered by the annual fee paid by the partnering Society. RTTs have a dedicated platform aimed at supporting their career development and RTT representation. Additionally, it also allows for a united voice of RTTs with common interests and more visibility for the societies within the Alliance.

The RTT Alliance membership encourages RTTs to become involved in ESTRO activities. It is an opportunity to guarantee better representation of RTTs, for improved recognition of the profession in the treatment of cancer patients.

Additionally, the benefits of the RTT Alliance go beyond individual membership:  RTT national groups and societies are united – under the umbrella of the RTT committee – to realise these common goals, while retaining the autonomy of the independent entities.
