Topics in Veterinary Oncology is an onsite & online congress on Small Animal Clinical Oncology
Topics in Veterinary Oncology (formerly ONCOlogisch Treffen or the Dutch International
Veterinary Oncology Conference) has been organized for the past 19 years.
The congress' subject is always centered around 1 topic. This can be:
an organ system (GI, respiratory, skin...),
a tumor type (neuro-endocrine, soft tissue sarcomas...),
a species (feline) or a presentation (emergency oncology)
The subject is always discussed in-depth by:
a medical oncologist, a surgical oncologist,
a radiotherapist, a diagnostic imager and/or a pathologist (depending on the subject)
congress language is English
