Both professionals and associations are welcome to join the SIOPE community. Individual membership still remains under the administration of the SIOP office in Eindhoven, the Netherlands. Associations which are interested in associate membership can apply directly via the SIOPE office in Brussels.

Over 700 professionals across Europe are members of SIOP Europe (SIOPE). Individual membership is interdisciplinary and incorporates oncologists, radiotherapists, surgeons, nurses and scientists. SIOPE is currently expanding its associate membership, in particular targeting national clinical trials groups, nurses and parent organisations.

SIOPE has also developed a new category of subscribership for stakeholders to access all online benefits exclusive to subscribers such as our community databases, online subscription to EJC at an especially reduced rate for SIOPE subscribers, as well as significant savings on fees to attend the joint  ECCO and ESMO Multidisciplinary Congresses, the first of which will take place in Berlin, 21-24 September 2009.
