Testing Strategies to Treat Drug-Resistant Hemangiosarcomas

Canine hemangiosarcoma is a common and highly metastatic cancer that affects all breeds of dogs. These tumors are particularly drug resistant, which makes them difficult to treat. The investigators recently identified a more drug-resistant cell population in hemangiosarcoma. These cells appear to be extremely efficient in isolating cancer drugs and preventing them from reaching their targets. The investigators will use several strategies to try to disrupt this process and they will determine whether any of these approaches improves drug responses and diminishes drug resistance. This could lead to more effective treatment of this difficult cancer.
