WSN is a cooperative group gathering the main reference centres for sarcomas around the World dedicated to the development and the support of innovative and collaborative clinical trials and to the drug development in Sarcomas.

The WSN has been created to stimulate rapid clinical drug development for sarcomas and enable performant clinical studies that could not be completed by the cooperative groups at a National level.

Sarcomas are rare tumors representing more than 150 diseases for which clinical studies on targeted therapies are not possible at the national level, what makes an international collaboration mandatory.

The WSN intends to:

•  Serve as a communication and facilitation platform between cooperative sarcoma clinical research groups worldwide
•  Stimulate discussions between designated representatives of the participating cooperative groups, with a focus on collaborations in trial execution
