Clinical trials and collaborative research in surgical oncology are actively encouraged by the VSSO. Prospective clinical trials are preferred, but multi-institutional retrospective case series will also be strongly considered. Research projects can include, but are not limited to, the study of new surgical techniques, multimodality treatment protocols, novel adjuvant agents, and treatment outcomes for different tumor types.

VCS Clinical Trials

The Veterinary Cancer Society has established a webpage dedicated to Clinical Trials. This page addresses many questions concerning clinical trials and is an excellent source for those searching for treatment for their pet. Additionally, active clinical trials can be found at that site.
