Clinical Trials for Histiocytic Sarcoma
Histiocytic sarcoma is an aggressive cancer arising from histiocytic cells that can affect dogs and cats in localized or disseminated forms. It is particularly prevalent in Bernese Mountain Dogs, Flat-Coated Retrievers, and Rottweilers. University research programs are studying new combination chemotherapy and immunotherapy protocols through funded clinical trials to improve the currently poor prognosis.

Understanding Histiocytic Sarcoma in Pets
Histiocytic sarcoma arises from immune cells called histiocytes and can appear in a single location or spread throughout the body. It tends to move quickly and can be difficult to treat.
Who it tends to affect
- Typical size: Affects both dogs and cats; in dogs, certain large breeds are particularly affected
- Typical age: Most commonly diagnosed in middle-aged to older dogs; somewhat less common in cats
Breeds it's seen in more often
Bernese Mountain Dogs, Flat-Coated Retrievers, Rottweilers.
This is which breeds tend to develop histiocytic sarcoma — not a list of who can join a trial. See eligibility below.
Can my pet join — does breed matter?
Trials typically enroll based on whether the disease is localized or disseminated, prior treatment, and overall health. Dogs and cats of all breeds may participate. The listed breeds have the strongest documented predisposition in dogs.
Most trials are open to all breeds and set requirements by size, weight, age, and diagnosis instead. Our matching service checks your pet's specific details against each study's actual requirements.
