Identification of new candidate biomarkers to support doxorubicin treatments in canine cancer patients.

Background: Both human and veterinary cancer chemotherapy are undergoing a paradigm shift from a "one size fits all" approach to more personalized, patient-oriented treatment strategies. Personalized chemotherapy is dependent on the identification and validation of biomarkers that can predict treatment outcome and/or risk of toxicity. Many cytotoxic chemotherapy agents, including doxorubicin, base their mechanism of action by interaction with DNA and disruption of normal cellular processes.
