Designed for researchers and medical professionals, the annual DTRF International Desmoid Tumor Research Workshop is a critically important, collaborative event bringing together some of the brightest minds in the field of desmoid tumors from a variety of disciplines. It presents the latest information on desmoid treatments and research, and facilitates new collaborations to move the science forward. The Workshop also helps us identify research priorities for the coming years. We are sincerely grateful to our attendees who play a key role in advancing the field.
The DTRF International Research Workshop features:
- Scientific talks on current research and treatment
- A forum to share research findings, develop new collaborations, bring new scientists into the desmoid tumor research field, and discuss innovations that will lead to new treatments
- Live questions/answers and discussions related to the scientific talks
- Group discussions focusing on gaps in desmoid tumor science and how best to address them through high impact collaborative research
The DTRF International Research Workshop is part of the DTRF Together We Will Weekend. In order to attend the Workshop, you need to register for the Weekend.
