BACKGROUND: Canine lymphoma is one of the most frequently occurring malignant neoplasms in dogs. Anthracycline-based chemotherapy for the treatment of canine lymphoma is very effective; however, there is not enough evidence for the development of cardiac toxicity using several anthracyclines as chemotherapeutic agents.
CASE DESCRIPTION: An 8-year-old, castrated, mixed-breed dog was diagnosed with multicentric lymphoma and received multi-agent chemotherapy. Complete remission was achieved, but the patient had a relapse of lymphoma. After third-line chemotherapy with epirubicin, the patient was diagnosed with dilated cardiomyopathy. The total cumulative doses of doxorubicin, mitoxantrone, and epirubicin were 125, 8, and 125 mg/m2, respectively. Although the patient was treated with cardiac drugs and clinically stabilized, the patient had a relapse of lymphoma and died shortly after the diagnosis of cardiomyopathy.
CONCLUSION: The patient was suspected to have anthracycline-induced cardiomyopathy. Further studies are required to establish prevention and management strategies for dogs receiving potentially cardiotoxic therapies, such as anthracyclines.
