Dear Michelle:
The response to chemotherapy of lymphomas in ferrets is less than
10%, and probably a significant percentage of those cases were
misdiagnosed.
I don't want to be pessimistic, but the odds don't bear out waiting
for chemotherapy drugs. The odds of a response to traditional
chemotherapy (cyclophosphamide, vincristine, and prednisone, with or
without asparaginase) are little better than prednisone alone.
My general counsel is that everyone has to make the decision for
themselves, but prednisone usually gives 2-4 months of quality time,
as the tumors usually shrink noticeably, and the animal returns to
normal at least for a while. When it comes back, it comes back with
a vengeance, and nothing stops it. However, prednisone can be given
orally with minimal problems.
Chemotherapeutic agents must be given via IV catheter, and require
trips to the vet at least weekly. They can be asociated with
significant side effects, and the stress of administration often
results in a decreased quality of life. Factor this against the
minimal extra time gained by most protocols over simple pred
administration, and you can tell why I generally take the prednisone
only route for my own ferrets.
With kindest regards,
Bruce H. Williams, DVM
