From our Members
  • CTOS is a one of the few organizations where scientists, clinicians, and other people interested in sarcomas can gather to hear about the latest work in a number of specialties, be it pediatric oncology, translational research, radiology, surgery, radiation oncology, medical oncology, and more. The program offers a primer or refresher on this rare group of diseases, and provides opportunities for fellows and faculty alike to discuss the latest research and to stimulate new projects for the subsequent year. I am a strong believer in interdisciplinary research, and CTOS provides a forum for this work that is unique in oncology.

  • CTOS has been growing to become the forum where leading professionals devoted to the diagnosis, treatment and research in the field of mesenchymal tumors meet; share experience, information and ideas; and plan studies. Its friendly environment has contributed significantly to advance the management of these challenging neoplasms as CTOS has facilitated the sharing of experiences and knowledge from around the globe, and has advanced our understanding of the biological background for looking for new therapies. I have always felt the Society as a family of people I am part of and consider the annual meeting the most important academic meeting of the year.
