Topics in Veterinary Oncology is
an on-site & on-line congress
on Small Animal Clinical Oncology
Topics in Veterinary Oncology (a.k.a. ONCOlogisch Treffen or the Dutch International
Veterinary Oncology Conference) has been organized for the past 21 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 body part (head & neck),
a species (feline) or a presentation (emergency oncology).
The subject is always discussed in-depth by:
a medical oncologist, a surgeon/surgical oncologist, a radiotherapist, a diagnostic imager, a pathologist (depending on the subject) and/or
a specialist on a specific subject (e.g. ophthalmologist, neurologist...).
We always invite a key-note lecture on the subject.
congress language is English
The congress can be attended live on-site, streamed live on-line, or viewed on-demand afterwards,
or any combination of the above; price is the same.
