Feline Fibrosarcoma Study



Injection-site sarcomas are devastating tumors in cats, which occur at sites of a previous injection or vaccination. Vaccines were first suspected as an underlying cause of these sarcomas, but other types of injections also appear to cause the tumors. The laboratory of Dr. Marlene Hauck is evaluating the genetic changes that are seen in these tumors along with genetic changes seen in spontaneously arising sarcomas and injection site reactions. Our goal is to identify potential targets for treatment and prevention to improve the outcome for cats with sarcomas.

Testing Requirement:

A biopsy sample is obtained from the sarcoma for the genetic analysis. This can occur at NCSU or at the primary veterinarian.


Any cat diagnosed with an injection-site sarcoma or spontaneously arising sarcoma. The biopsy must be placed immediately in a RNA preserving solution.

Financial Incentive:

There is no financial incentive to take part in this study. We are happy to ship the RNA preservative solution to any veterinarian performing a biopsy on a cat suspected of one of the above conditions.
